Medicare exacts a penalty whenever it deems that hospitals have too many patients with chronic obstructive pulmonary disease who have been re-admitted within 30 days of discharge for care related to the disease. For acute-care hospitals the solution to reducing chronic obstructive pulmonary disease (COPD) re-admissions has been elusive, but members of a COPD chronic care management collaborative think they have found at least a partial solution.

Among 33 centers participating in the performance improvement program, the aggregated cost avoidance for emergency department (ED) visits was estimated at $351,000, and the savings for hospital re-visits avoided was an estimated $2.6 million, reported Valerie Press, MD, MPH, from the University of Chicago, and co-authors from the health care performance-improvement company Vizient.

The investigators described their chronic care management collaborative in a thematic poster presented during the American Thoracic Society’s virtual international conference (Abstract A1688).

“I’ve been working in the space of COPD re-admissions pretty much since Medicare started its penalty program,” Dr. Press said in an interview.

“At both my own institution and nationally, we’ve been trying to understand the policy that went into place to reduce what was considered to be excessive readmissions after a COPD admission, but there really wasn’t a lot of evidence to suggest how to do this at the time the policy went into place,” she said.

The Centers for Medicare & Medicaid Services (CMS) initiated its Hospital Readmission Reduction Program for COPD in 2014.

“The challenge with COPD is that we have not found really successful interventions to decrease readmissions,” commented Laura C. Myers, MD, MPH, in an interview. Dr. Myers, who studies optimal care delivery models for patients with COPD at Kaiser Permanente Northern California in Oakland, was not involved in the study.

She said that although the aggregate cost savings in the study by Dr. Press and colleagues are relatively modest, “if you extrapolate across the country, then those numbers could potentially be impressive.”
 

Collaboration details

Dr. Press was a subject matter expert for the collaborative, which included 47 Vizient member sites in the Southeast, Southwest, Midwest, and Northeast and Northwest coasts. Of these centers, 33 completed both parts of the collaboration.

The program included bi-monthly didactic sessions and site report and discussion sessions with peer-to-peer networking for a total of 6 months. During the sessions, meeting participants discussed best practices, received expert coaching, and provided progress updates on performance improvement projects.

“The goal was for them to identify the gaps or needs they had at their hospitals or practices, and then to try to put in place one or more interventions,” Dr. Press said. “This wasn’t a research program. It wasn’t standardized, and not all hospitals had to do the same program.”

The participants submitted reports for baseline and post-collaboration periods on both an intervention’s “reach,” defined as the percentage of patients who received a specified intervention, and on two outcome measures.

The interventions measured included spirometry, follow-up visits scheduled within 7 to 14 days of discharge, patients receiving COPD education, pulmonary referrals, and adherence to the COPD clinical pathway.

The outcome measures were the rate of COPD-related ED visits and hospital readmissions.
 

Revisits reduced

At the end of the program, 83% of participating sites had reductions in either ED visits or readmissions, and of this group, five sites had decreases in both measures.

Among all sites with improved metrics, the average rate of COPD-related ED revisits declined from 12.7% to 9%, and average inpatient readmissions declined from 20.1% to 15.6%.

As noted, the estimated cost savings in ED revisits avoided was $351,00, and the estimated savings in hospital readmission costs was $2.6 million.

“Although the centers didn’t have to participate in both parts, we did see in our results that the programs that participated fully had better results,” Dr. Press said.

“Historically, we’ve had such difficulty in decreasing COPD readmissions, and it’s nice to see something that actually works, both for patients and for conserving health resources,” Dr. Myers commented.

The study was supported by Vizient. Dr. Press disclosed honoraria from the company in her role as subject matter expert. Dr. Myers reported no conflicts of interest.

The inflammatory cytokine interleukin 6 may be a biomarker for distant recurrence of breast cancer among patients treated for stage II-III HER2-negative disease, investigators have found.

In a case-control study of 498 women with breast cancer treated with surgery and adjuvant chemotherapy, as well as endocrine therapy for women with estrogen receptor (ER)–positive tumors, those with higher serum levels of IL-6 at diagnosis had a significantly greater risk for disease recurrence than women with lower levels of the cytokine, Joseph A. Sparano, MD, from the Albert Einstein College of Medicine and Montefiore Medical Center, New York, and colleagues reported.

“This analysis provides level 1B evidence indicating that higher levels of the cytokine IL-6 at diagnosis are associated with a significantly higher distant recurrence risk in high-risk stage II-III breast cancer despite optimal adjuvant systemic therapy,” they wrote in a study presented in a poster discussion session at the American Society of Clinical Oncology Annual Meeting.(Abstract 520)

In an interview, Dr. Sparano said that their findings first need to be validated in a larger study.

“When validated, I think the other key issue is to try to understand what the best cut point for identifying high risk is, “ he said.

If further studies confirm that higher IL-6 levels are prognostic for worse outcomes, it might be possible to use levels of the cytokine as a biomarker to predict for therapies targeting the IL-6/Janus kinase/STAT3 pathway.

“There are trials ongoing testing IL-6 antibodies in combination chemotherapy, and this could be a rational biomarker to identify which patients would be more likely to benefit from that approach,” he said.
 

Systemic inflammation

Systemic inflammation is suspected as a contributing factor to cancer progression and disease recurrence, Dr. Sparano and colleagues noted.

To test their hypothesis that inflammatory cytokines and/or chemokines could be associated with distant recurrence, they conducted a case-control study with 249 matched pairs of patients enrolled in a phase 3 trial of adjuvant chemotherapy for lymph-node positive and high-risk lymph-node negative breast cancer (NCT00433511).

The patients all had surgery and adjuvant chemotherapy with doxorubicin, cyclophosphamide, and paclitaxel with or without bevacizumab, and endocrine therapy for patients whose tumors were ER positive.

They used propensity score matching to pair each patient with distant recurrence to one without, with covariates including post versus premenopausal or perimenopausal status, estrogen and/or progesterone receptor positivity, tumor size (less than 2 cm, greater than 2-5 cm, or greater than 5 cm) nodal status, and grade.

The only biomarker that met the prespecified boundary for statistical significance (P < .0014) was IL-6, with a hazard ratio for distant recurrence of 1.37 (P = .0006).

The median and mean values for IL-6 were 0.95 and 7.5 pg/mL, respectively

Other substances associated with distant recurrence (with a two-sided P value < .05) were macrophage-derived chemokine/CCL22 (HR, 1.90; P = .0098), IL-17A, a T-helper cell inflammatory cytokine (HR, 1.36; P = .0052), and the cytokine vascular endothelial growth factor A (VEGF-A, HR, 1.13; P = 0.037).

There was no statistical interaction between VEGF-A levels and the benefit of bevacizumab.
 

Prognostic value, not clinical utility

“This is a nice abstract. It looks at inflammatory cytokines and provides evidence that inflammatory cytokines, particularly IL-6, could have a prognostic role in predicting risk of recurrence in HER2-negative disease, and the team did a very nice job in multivariate analysis looking at different factors,” said Aditya Bardia, MD, MPH, from the Mass General Cancer Center in Boston, the invited discussant for the study.*

In an interview, Dr. Bardia said that the finding “provides prognostic value, but does not provide clinical utility. It’s unclear if we used this assay and it identified that a patient was at high risk of recurrence whether we could change that. Is there any intervention that could be done to potentially alter the course of disease, alter the natural history? That’s unknown.”

He agreed with Dr. Sparano and colleagues that validation of the finding was still needed, ideally in a prospective or retrospective cohort study.

The study was supported by grants from the National Cancer Institute, Komen Foundation, and Breast Cancer Research Foundation. Dr. Sparano disclosed relationships with multiple companies. Dr. Bardia disclosed a consulting or advisory role and research funding to his institution from multiple companies.

Data from a small retrospective study suggest that venetoclax-based regimens may have activity against relapsed or refractory T-lineage acute lymphoblastic leukemia (T-ALL) in children and young adults.

Among seven patients with T-ALL treated with venetoclax (Venclexta) in combination with chemotherapy, four had complete remissions and one had a CR with incomplete recovery of blood counts (CRi), and all four patients had undetectable minimal residual disease (MRD), reported pediatric hematology/oncology fellow Amber Gibson, MD, and colleagues from the University of Texas MD Anderson Cancer Center Children’s Cancer Hospital in Houston.

“This single-institution retrospective review found that venetoclax was safe and well tolerated in combination chemotherapy regimens, thrombocytopenia and neutropenia were the most common toxicities identified, [and] venetoclax should be considered for patients with refractory T-cell ALL and investigated as up-front therapy for this patient population,” they wrote in the abstract accompanying a poster presentation at the annual meeting of the American Society of Pediatric Hematology/Oncology.

Children with relapsed T-ALL and T-lymphoblastic lymphoma (T-LL) have a dismal prognosis, with a 3-year event-free survival rate less than 10%, according to the researchers.

To see whether venetoclax, an inhibitor of the antiapoptotic protein B-cell lymphoma-2 (BCL-2), could improve outcomes for children with ALL, the investigators conducted a retrospective chart review of the safety and efficacy of venetoclax in young patients with relapsed/refractory ALL/LL who received the drug at their center.

They identified 10 patients aged 6-21 years (median, 18), 5 of whom had T-ALL (1 with early T-cell precursor ALL), 2 with T-LL, and 3 with B-lineage ALL (B-ALL).

The median number of prior lines of therapy was 3.5. Three of the 10 patients had received hematopoietic stem cell transplants, and the 3 patients with B-ALL had all received prior CD19-directed chimeric antigen receptor T-cell (CAR T) therapy. One of these patients received a dual CD19/CD22 CAR T product, one received CD19-directed blinotumumab.

There were no new safety signals with venetoclax, no treatment-related deaths, and no deaths within 30 days of starting venetoclax.

All 10 patients had grade 4 thrombocytopenias, 6 had grade 4 neutropenia, 3 had grade 4 febrile neutropenia, 2 had grade 4 anemia, and 1 each had grade 4 sepsis, pneumonia, or coagulopathy.

As noted, there were three CRs and one CRi, all in patients with T-ALL. All four of these patients were MRD negative by flow cytometry at a median of 22 days. The median duration of response was 17.4 months (range, 2-18 months).

At the most recent follow-up five patients were still alive, three without disease, one was still undergoing treatment, and one was alive following an allogeneic HSCT.
 

Early studies

Shilpa Shahani, MD, a pediatric oncologist and assistant clinical professor of pediatrics at City of Hope in Duarte, Calif., who was not involved in the study, said that there are early studies exploring the use of venetoclax in infants with ALL.

“Venetoclax is a BCL-2 inhibitor that is pretty well tolerated, but you can also have cytopenias with it,” she said.

She noted that it is not typically used in the frontline setting in pediatric populations, but may be considered for patients with difficult-to-treat disease or for whom the relatively good toxicity profile might be appropriate.

The MD Anderson investigators did not report a funding source. The authors and Dr. Shahani reported no relevant conflicts of interest.

To see whether venetoclax, an inhibitor of the antiapoptotic protein B-cell lymphoma-2 (BCL-2), could improve outcomes for children with ALL, the investigators conducted a retrospective chart review of the safety and efficacy of venetoclax in young patients with relapsed/refractory ALL/LL who received the drug at their center.

They identified 10 patients aged 6-21 years (median, 18), 5 of whom had T-ALL (1 with early T-cell precursor ALL), 2 with T-LL, and 3 with B-lineage ALL (B-ALL).

The median number of prior lines of therapy was 3.5. Three of the 10 patients had received hematopoietic stem cell transplants, and the 3 patients with B-ALL had all received prior CD19-directed chimeric antigen receptor T-cell (CAR T) therapy. One of these patients received a dual CD19/CD22 CAR T product, one received CD19-directed blinotumumab.

There were no new safety signals with venetoclax, no treatment-related deaths, and no deaths within 30 days of starting venetoclax.

All 10 patients had grade 4 thrombocytopenias, 6 had grade 4 neutropenia, 3 had grade 4 febrile neutropenia, 2 had grade 4 anemia, and 1 each had grade 4 sepsis, pneumonia, or coagulopathy.

As noted, there were three CRs and one CRi, all in patients with T-ALL. All four of these patients were MRD negative by flow cytometry at a median of 22 days. The median duration of response was 17.4 months (range, 2-18 months).

At the most recent follow-up five patients were still alive, three without disease, one was still undergoing treatment, and one was alive following an allogeneic HSCT.
 

Early studies

Shilpa Shahani, MD, a pediatric oncologist and assistant clinical professor of pediatrics at City of Hope in Duarte, Calif., who was not involved in the study, said that there are early studies exploring the use of venetoclax in infants with ALL.

“Venetoclax is a BCL-2 inhibitor that is pretty well tolerated, but you can also have cytopenias with it,” she said.

She noted that it is not typically used in the frontline setting in pediatric populations, but may be considered for patients with difficult-to-treat disease or for whom the relatively good toxicity profile might be appropriate.

The MD Anderson investigators did not report a funding source. The authors and Dr. Shahani reported no relevant conflicts of interest.

Adults in their 30s, 40s and 50s with chronic obstructive pulmonary disease (COPD) experience significant morbidity and excess mortality from the disease, results of a population-based study show.

Among adults aged 35-55 years with COPD in Ontario in a longitudinal population cohort study, the overall mortality rate was fivefold higher, compared with other adults in the same age range without COPD.

In contrast, the mortality rate among adults 65 years and older with COPD was 2.5-fold higher than that of their peers without COPD, reported Alina J. Blazer, MSc, MD, a clinical and research fellow at the University of Toronto.

“Overall, our study has shown that younger adults with COPD experience significant morbidity, as evidence by their elevated rates of health care use and excess mortality from their disease. This study provides further evidence that so-called ‘early’ COPD is not a benign disease, and suggests that we should focus clinical efforts on identifying COPD in younger patients, in the hopes that earlier intervention may improve their current health, reduce resource utilization, and prevent further disease progression,” she said during a minisymposium at the American Thoracic Society’s virtual international conference (Abstract A1131).

COPD is widely regarded as a disease affecting only older adults, but it can also occur in those younger than 65, and although it is commonly assumed that COPD diagnosed earlier in life will be milder in severity, this assumption has not been fully explored in real-world settings, Dr. Blazer said.

She and her colleagues conducted a study to examine disease burden as measured by health services utilization and mortality among younger adults with COPD, and compared the rates with those of older adults with COPD.

The sample for this study included 194,759 adults with COPD aged 35-55 years in Ontario in 2016. COPD was identified from health administrative data for three or more outpatient claims or one or more hospitalization claims for COPD over a 2-year period.

For context, the data were compared with those for 496,2113 COPD patients aged 65 years and older.

They found that, compared with their peers without the disease, younger adults had a 3.1-fold higher rate of hospitalization for any cause, a 2.2-fold higher rate of all-cause ED visits, and a 1.7-fold higher rate of outpatient visits for any cause.

In contrast, the comparative rates for seniors with versus without COPD were 2.1-fold, 1.8-fold, and 1.4-fold, respectively.

As noted before, the mortality rate for younger adults with COPD was 5-fold higher than for those without COPD, compared with 2.5-fold among older adults with COPD versus those without.
 

Earlier diagnosis, follow-up

“A very important talk,” commented session comoderator Valerie Press, MD, MPH, from the University of Chicago. “I know that there’s a lot of work to be done in earlier diagnosis in general, and I think starting with the younger population is a really important area.”

She asked Dr. Blazer about the possibility of asthma codiagnosis or misdiagnosis in the younger patients.

“We use a very specific, validated case definition in the study that our group has used before, and the specificity is over 96% for physician-diagnosed COPD, at the expense of sensitivity, so if anything we probably underestimated the rate of COPD in our study,” Dr. Blazer said.

Audience member Sherry Rogers, MD, an allergist and immunologist in private practice in Syracuse, N.Y., asked whether the investigators could determine what proportion of the excess mortality they saw was attributable to COPD.

“This was looking at all-cause mortality, so we don’t know that it’s necessarily all attributable to COPD per se but perhaps also to COPD-attributable comorbidities,” Dr. Blazer said. “It would be important to piece out the actual causes of mortality that are contributing to that elevated [morality] in that population.”

She added that the next step could include examining rates of specialty referrals and pharmacotherapy to see whether younger patients with COPD are receiving appropriate care, and to ascertain how they are being followed.

The study was supported by the University of Toronto and Sunnybrook Research Institute. Dr. Blazer reported no conflicts of interest to disclose.

The benefits of a triple fixed-dose inhaled corticosteroid, long-acting muscarinic antagonist, and long-acting beta₂ agonist combination extend to patients with moderate as well as severe chronic obstructive pulmonary disease (COPD).

That’s according to investigators in the ETHOS (Efficacy and Safety of Triple Therapy in Obstructive Lung Disease) trial (NCT02465567).

In a subanalysis of data on patients with moderate COPD who were enrolled in the comparison trial, the single-inhaler combination of the inhaled corticosteroid (ICS) budesonide, the long-acting muscarinic antagonist (LAMA) glycopyrrolate, and the long-acting beta₂ agonist (LABA) formoterol fumarate (BGF) showed benefits in terms of COPD exacerbations, lung function, symptoms, and quality-of-life compared with either of two dual therapy combinations (glycopyrrolate or budesonide with formoterol [GFF/BFF]).

“A moderate benefit:risk ratio was demonstrated in patients with moderate COPD, consistent with the results of the overall ETHOS population, indicating the results of the ETHOS study were not driven by patients with severe or very severe COPD,” wrote Gary T. Ferguson, MD, from the Pulmonary Research Institute of Southeast Michigan in Farmington Hills, and colleagues. Their poster was presented during the American Thoracic Society’s virtual international conference. (Abstract A2244).

As reported at ATS 2020, in the overall ETHOS population of 8,509 patients with moderate to very severe COPD the annual rate of moderate or severe COPD exacerbations was 1.08 and 1.07 for the triple combinations with 320-mcg and 160-mcg doses of budesonide, respectively, compared with 1.42 for glycopyrrolate-formoterol, and 1.24 for budesonide-formoterol.

Both triple combinations were significantly superior to the dual therapies for controlling exacerbations, Klaus F. Rabe, MD, PhD, of LungenClinic Grosshansdorf and Christian-Albrechts University Kiel (Germany), and colleagues found.
 

Subanalysis details

At the 2021 iteration of ATS, ETHOS investigator Dr. Ferguson and colleagues reported results for 613 patients with moderate COPD assigned to BGF 320 mcg, 604 assigned to BGF 160 mcg, 596 assigned to GFF, and 614 randomized to BFF.

Baseline demographic and clinical characteristics were similar among the groups, including age, sex, smoking status, mean COPD Assessment Test (CAT) score, mean blood eosinophil count, ICS use at screening, exacerbations in the previous year, mean postbronchodilator forced expiratory volume in 1 second (FEV₁) percentage of predicted, and mean postbronchodilator percentage reversibility.

A modified intention-to-treat (ITT) analysis showed that the rate of moderate or severe exacerbations over 52 weeks with BGF 320 mcg was 21% lower than with GFF (P = .0123), but only 4% lower than with BFF, a difference that was not statistically significant.

The BGF 160-mg dose was associated with a 30% reduction in exacerbations vs. GFF (P = .0002), and with a nonsignificant reduction of 15% compared with BFF.

­There was a numerical but not statistically significant improvement from baseline at week 24 in morning pre-dose trough FEV₁ between the BGF 320-mcg dose and GFF (difference 47 mL), and a significant improvement (90 mL) with BGF compared with BFF (P = .0006). The BGF 160-mcg dose was associated with a larger improvement (89 mL) compared with BFF (P = .0004) but not with GFF.

The FEV₁ area under the curve (AUC) of receiver operating characteristics from 0 to 4 hours was superior with BGF at both doses compared with both GFF and BFF.

Patients who used BGF 320 mcg also used significantly less rescue medication over 24 weeks compared with patients who used GFF (P < .0001) or BFF (P = .0001). There were no significant differences in rescue medication use between the BGF 160-mg dose and either of the dual therapy combinations.

Time to clinically important deterioration – defined as a greater than ­100 mL decrease in trough FEV₁, or a ­4 units increase in St. George’s Respiratory Questionnaire total score, or a treatment-emergent moderate/severe COPD exacerbation occurring up to week 52 – was significantly longer with the 320-mcg but not 160-mcg BGF dose compared with GFF (P = .0295) or BFF (P = .0172).
 

Safety

Treatment-emergent adverse events (TEAEs) occurred in about two-thirds of patients in each trial arm, although TEAEs related to study treatment were more common with the two triple-therapy combinations and with BFF than with GFF.

TEAEs leading to study discontinuation occurred in 5.5% of patients on BGF 320 mcg, 4% on BGF 160 mcg, 4.5% on GFF, and 3.2% on BFF.

Confirmed major adverse cardiovascular events occurred in 0.8% and 1.5% in the BGF 320- and 160-mcg groups, respectively, in 1.8% of patients in the GFF arm, and 1.5% in the BFF arm.

Confirmed pneumonia was seen in 2.6% of patients in each BGF arm, 2.2% in the GFF arm, and 3.6% in the BFF arm.
 

Selected population

In a comment, David Mannino, MD, medical director of the COPD Foundation, who was not involved in the study, noted that the enrollment criteria for ETHOS tended to skew the population toward patients with severe disease.

In the trial, all patients were receiving at least two inhaled maintenance therapies at the time of screening, and had a postbronchodilator ratio of FEV₁ to forced vital capacity of less than 0.7, with a postbronchodilator FEV₁ of 25%-65% of the predicted normal value. The patients all had a smoking history of at least 10 pack-years and a documented history of at least one moderate or severe COPD exacerbation in the year before screening.

“The question was whether they would see the same results in people with more moderate impairment, and the answer in this subanalysis is ‘yes.’ The findings weren’t identical between patients with severe and moderate disease, but there were similarities with what was seen in the overall ETHOS study,” he said.

The ETHOS Trial was supported by Pearl Therapeutics. Dr. Ferguson reported grants, personal fees, and nonfinancial support from AstraZeneca during the conduct of the study; and grants, fees, and nonfinancial support from Pearl and others. Dr. Mannino reports recruitment to an advisory board for AstraZeneca.

In the trial, all patients were receiving at least two inhaled maintenance therapies at the time of screening, and had a postbronchodilator ratio of FEV₁ to forced vital capacity of less than 0.7, with a postbronchodilator FEV₁ of 25%-65% of the predicted normal value. The patients all had a smoking history of at least 10 pack-years and a documented history of at least one moderate or severe COPD exacerbation in the year before screening.

“The question was whether they would see the same results in people with more moderate impairment, and the answer in this subanalysis is ‘yes.’ The findings weren’t identical between patients with severe and moderate disease, but there were similarities with what was seen in the overall ETHOS study,” he said.

The ETHOS Trial was supported by Pearl Therapeutics. Dr. Ferguson reported grants, personal fees, and nonfinancial support from AstraZeneca during the conduct of the study; and grants, fees, and nonfinancial support from Pearl and others. Dr. Mannino reports recruitment to an advisory board for AstraZeneca.

Sex-specific differences in the severity of symptoms and prevalence of comorbidities in patients with chronic obstructive pulmonary disease (COPD) may point to different criteria for diagnosing cardiac comorbidities in women and men, a retrospective analysis suggests.

Among 2,046 patients in the German COSYCONET (COPD and Systemic Consequences–Comorbidities Net) cohort, most functional parameters and comorbidities and several items on the COPD Assessment Test (CAT) differed significantly between men and women.

In addition, there were sex-specific differences in the association between symptoms and cardiac disease, Franziska C. Trudzinski, MD, from the University of Heidelberg (Germany), and colleagues reported.

(Note: Although the authors used the term “gender” to distinguish male from female, this news organization has used the term “sex” in this article to refer to biological attributes of individual patients rather than personal identity.)

“[Sex]-specific differences in COPD comprised not only differences in the level of symptoms, comorbidities, and functional alterations but also differences in their mutual relationships. This was reflected in different sets of predictors for cardiac disease,” they wrote in a thematic poster presented at the American Thoracic Society’s virtual international conference.
 

GOLD standard

The investigators conducted an analysis of data on 795 women and 1,251 men with GOLD (Global Initiative for Chronic Obstructive Lung Disease) class 1-3 disease from the COSYCONET COPD cohort.

They looked at the patients’ clinical history, comorbidities, lung function, CAT scores, and modified Medical Research Council (mMRC) dyspnea score.

The authors used multivariate regression analysis to model potential sex-related differences in the relationship between symptoms in general and CAT items in particular, and the pattern of comorbidities and functional alterations.

They also performed logistic regression analyses to identify predictors for cardiac disease, defined as myocardial infarction, heart failure, or coronary artery disease. The analyses were controlled for age, body mass index (BMI), smoking status, mMRC, CAT items, and z scores of forced expiratory volume in 1 second/forced vital capacity ratio.

The investigators found significant differences between men and women for most functional parameters and comorbidities, and for CAT items of cough (item 1), phlegm (item 2), and energy (item 8; P < .05 for all comparisons).

In logistic regression analysis, predictors for cardiac disease in men were energy (CAT item 8), mMRC score, smoking status, BMI, age, and spirometric lung function.

In women, however, only age was significantly predictive for cardiac disease.

“Our findings give hints how diagnostic information might be used differently in men and women,” Dr. Trudzinski and colleagues wrote.
 

Reassuring data

David Mannino, MD, medical director of the COPD Foundation, who was not involved in the study, said in an interview that sex differences in COPD presentation and severity are common.

“In general, men and women report symptoms differently. For example, women don’t report a whole lot of chronic bronchitis and phlegm, although they may have it,” he said, “whereas men may report less dyspnea. It varies, but in general we know that men and women, even with the same type of disease, report symptoms differently.”

Comorbidities also differ between the sexes, he noted. Women more frequently have osteoporosis, and men more frequently have heart disease, as borne out in the study. The prevalence of heart disease among patients in the study was approximately 2.5 times higher in men than women.

“It’s reassuring, because what we’re seeing is similar to what we’ve seen in other [studies] with regards to comorbidities,” he said.

The study was sponsored by Philipps University Marburg Medical Center, Germany. The authors and Dr. Mannino have reported no relevant financial relationships.

A study of COVID-19 outcomes across the United States bolsters reports from China and Europe that indicate that patients with chronic obstructive pulmonary disease (COPD) and SARS-CoV-2 infection have worse outcomes than those of patients with COVID-19 who do not have COPD.

Investigators at the University of Texas Medical Branch at Galveston, Texas, combed through electronic health records from four geographic regions of the United States and identified a cohort of 6,056 patients with COPD among 150,775 patients whose records indicate either a diagnostic code or a positive laboratory test result for COVID-19.

Their findings indicate that patients with both COPD and COVID-19 “have worse outcomes compared to non-COPD COVID-19 patients, including 14-day hospitalization, length of stay, ICU admission, 30-day mortality, and use of mechanical ventilation,” Daniel Puebla Neira, MD, and colleagues from the University of Texas Medical Branch reported in a thematic poster presented during the American Thoracic Society (ATS) 2021 virtual international conference.

A critical care specialist who was not involved in the study said that the results are concerning but not surprising.

“If you already have a lung disease and you develop an additional lung disease on top of that, you don’t have as much reserve and you’re not going to tolerate the acute COVID infection,” said ATS expert Marc Moss, MD, Roger S. Mitchell Professor of Medicine in the division of pulmonary sciences and critical care medicine at the University of Colorado, Aurora.

The evidence shows that “patients with COPD should be even more cautious, because if they get sick and develop, they could do worse,” he said in an interview.
 

Retrospective analysis

Dr. Neira and colleagues assessed the characteristics and outcomes of patients with COPD who were treated for COVID-19 in the United States from March through August 2020.

Baseline demographics of the patients with and those without COPD were similar except that the mean age was higher among patients with COPD (68.62 vs. 47.08 years).

In addition, a significantly higher proportion of patients with COPD had comorbidities compared with those without COPD. Comorbidities included diabetes, hypertension, asthma, chronic kidney disease, end-stage renal disease, stroke, heart failure, cancer, coronary artery disease, and liver disease (P < .0001 for all comparisons).

Among patients with COPD, percentages were higher with respect to the following parameters: 14-day hospitalization for any cause (28.7% vs. 10.4%), COVID-19-related 14-day hospitalization (28.1% vs. 9.9%), ICU use (26.3% vs. 17.9%), mechanical ventilation use (26.3% vs. 16.1%), and 30-day mortality (13.6% vs. 7.2%; P < .0001 for all comparisons).
 

‘Mechanisms unclear’

“It is unclear what mechanisms drive the association between COPD and mortality in hospitalized patients with COVID-19,” the investigators wrote. “Several biological factors have been proposed, including chronic lung inflammation, oxidative stress, protease-antiprotease imbalance, and increased airway mediators.”

They recommend use of multivariable logistic regression to tease out the effects of covariates among patients with COPD and COVID-19 and call for research into long-term outcomes for these patients, “as survivors of critical illness are increasingly recognized to have cognitive, psychological, and physical consequences.”

Dr. Moss said that in general, the management of patients with COPD and COVID-19 is similar to that for patients with COVID-19 who do not have COPD, although there may be “subtle” differences, such as ventilator settings for patients with COPD.

No source of funding for the study has been disclosed. The investigators and Dr. Moss have disclosed no relevant financial relationships.

Even in the age of intensive therapy and extensive risk stratification, there are small but significant differences in outcomes between boys and girls with B-lineage acute lymphoblastic leukemia (B-ALL).

This finding comes from a review of 10 years of clinical trials by the Children’s Oncology Group (COG), which showed that, among patients with B-ALL, 5-year event-free survival (EFS) and overall survival (OS) were inferior with boys, compared with girls, even when adjusted for prognostic factors, reported Sumit Gupta, MD, PhD, FRCPC, from the Hospital for Sick Children in Toronto.

“Inferior outcomes, although small in absolute terms, continue to exist among boys versus girls despite modern therapy and after adjusting for other risk factors. These persist also despite the longer duration of therapy among boys,” he said in an oral abstract presentation during the annual meeting of the American Society of Pediatric Hematology/Oncology. (Abstract 2025).

Among pediatric patients with T-cell lineage ALL (T-ALL), however, there were no significant sex-based differences in either EFS or OS, he said.

Although survival for children with ALL has continued to improve, previous studies found inferior survival outcomes in boys, and suggested that the difference might be explained by imbalances in risk factors.

To see whether sex-based disparities persist with modern intensive therapy protocols after adjustment for risk factors, and to determine whether there are sex-based differences in toxicities or patterns of treatment failure, Dr. Gupta and colleagues created a cohort of all patients age 1-30 years enrolled in frontline COG trial for B-ALL and T-ALL from 2004 to 2014.

During this period, boys received an extra year of maintenance. Cranial radiation was limited to B-ALL patients with slow treatment responses and central nervous system status 3, signifying definite CNS involvement. Among patients with T-ALL, cranial radiation was given to all intermediate- and high-risk patients.
 

Sex differences small, but significant

The investigators identified a total of 8,202 patients (4,463 males and 3,739 females) with B-ALL, and 1,562 (1,161 males and 401 females) with T-ALL. Boys were likely to be older (P < .0001), and to have a small but significantly greater likelihood of having unfavorable B-ALL cytogenetics, compared with girls (P = .05).

Boys with B-ALL were less likely to be negative for minimal residual disease (76.1% vs. 78.1%, P = .04), but the opposite was true for those with T-ALL (59% vs. 56.8%, P = .01).

As noted before, among pediatric patients with B-ALL, EFS and OS were both inferior for males, with a hazard ratio for higher EFS rates in girls of 1.19 (P = .001) and a HR for OS of 1.17 (P = .046).

Both EFS and OS were similar between the sexes among patients with T-ALL.

The differences in EFS in patients with B-ALL was attributable to higher CNS relapses among boys (4.2% vs. 2.5%, P < .0001). The CNS relapses occurred at a median of 2.5 years in boys versus 2.1 years in girls, although most relapses occurred during therapy.

There were no differences in cumulative isolated bone marrow relapses, however.

Treatment-related mortality rates were the same, but osteonecrosis rates were significantly lower for boys, with a 5-year cumulative incidence of 5.2% versus 6.7% for girls (P = .001).
 

Possible explanations

Dr. Gupta noted that the inferior outcomes among boys may be attributable to extramedullary relapses among patients with B-ALL.

In addition, the lack of sex-based differences in T-ALL may be caused in part by the increased use of CNS radiation in this population. Previous studies in which CNS radiation was omitted showed an increase in CNS relapsed rates among boys but not girls, he pointed out.

“This does imply that in the more recent generation of T-lineage ALL treatment trials that we’ll need to monitor sex-based differences in outcome, as fewer and fewer patients with T-ALL disease received cranial radiation in these more recent trials and in contemporary therapy,” he said.

One possible mechanism for sex-based outcome differences might be differences in steroid metabolism, as suggested by the higher osteonecrosis rate among girls, he added.

In the question-and-answer following the presentation, William G. Woods, MD, from Emory University, Atlanta, asked what role testicular relapse played in outcomes.

Dr. Gupta replied that the investigators had considered that the excess risk for extramedullary relapse in boys might be accounted for by testicular relapse, but “when you take away testicular relapse from those numbers and really just concentrate on CNS, it’s still that substantial difference when you’re talking about B-lineage disease.”

In patients with T-ALL as well, CNS relapse was more common in boys after controlling for testicular relapse, he said.

Another audience member asked whether the data suggest a benefit to treating boys with CNS-penetrating drugs such as dexamethasone or high-dose methotrexate,

Dr. Gupta said that it’s still uncertain whether it is clinically sound to subject a boy with otherwise–standard-risk disease to more intensive high-risk therapy, given the relatively small absolute differences in outcomes between the sexes.

The study was supported by grants from the National Cancer Institute and the St. Baldrick’s Foundation. Dr. Gupta, Dr. Woods, and Dr. Meret had no relevant conflicts of interest to report.

This finding comes from a review of 10 years of clinical trials by the Children’s Oncology Group (COG), which showed that, among patients with B-ALL, 5-year event-free survival (EFS) and overall survival (OS) were inferior with boys, compared with girls, even when adjusted for prognostic factors, reported Sumit Gupta, MD, PhD, FRCPC, from the Hospital for Sick Children in Toronto.

“Inferior outcomes, although small in absolute terms, continue to exist among boys versus girls despite modern therapy and after adjusting for other risk factors. These persist also despite the longer duration of therapy among boys,” he said in an oral abstract presentation during the annual meeting of the American Society of Pediatric Hematology/Oncology. (Abstract 2025).

Among pediatric patients with T-cell lineage ALL (T-ALL), however, there were no significant sex-based differences in either EFS or OS, he said.

Although survival for children with ALL has continued to improve, previous studies found inferior survival outcomes in boys, and suggested that the difference might be explained by imbalances in risk factors.

To see whether sex-based disparities persist with modern intensive therapy protocols after adjustment for risk factors, and to determine whether there are sex-based differences in toxicities or patterns of treatment failure, Dr. Gupta and colleagues created a cohort of all patients age 1-30 years enrolled in frontline COG trial for B-ALL and T-ALL from 2004 to 2014.

During this period, boys received an extra year of maintenance. Cranial radiation was limited to B-ALL patients with slow treatment responses and central nervous system status 3, signifying definite CNS involvement. Among patients with T-ALL, cranial radiation was given to all intermediate- and high-risk patients.
 

Sex differences small, but significant

The investigators identified a total of 8,202 patients (4,463 males and 3,739 females) with B-ALL, and 1,562 (1,161 males and 401 females) with T-ALL. Boys were likely to be older (P < .0001), and to have a small but significantly greater likelihood of having unfavorable B-ALL cytogenetics, compared with girls (P = .05).

Boys with B-ALL were less likely to be negative for minimal residual disease (76.1% vs. 78.1%, P = .04), but the opposite was true for those with T-ALL (59% vs. 56.8%, P = .01).

As noted before, among pediatric patients with B-ALL, EFS and OS were both inferior for males, with a hazard ratio for higher EFS rates in girls of 1.19 (P = .001) and a HR for OS of 1.17 (P = .046).

Both EFS and OS were similar between the sexes among patients with T-ALL.

The differences in EFS in patients with B-ALL was attributable to higher CNS relapses among boys (4.2% vs. 2.5%, P < .0001). The CNS relapses occurred at a median of 2.5 years in boys versus 2.1 years in girls, although most relapses occurred during therapy.

There were no differences in cumulative isolated bone marrow relapses, however.

Treatment-related mortality rates were the same, but osteonecrosis rates were significantly lower for boys, with a 5-year cumulative incidence of 5.2% versus 6.7% for girls (P = .001).
 

Possible explanations

Dr. Gupta noted that the inferior outcomes among boys may be attributable to extramedullary relapses among patients with B-ALL.

In addition, the lack of sex-based differences in T-ALL may be caused in part by the increased use of CNS radiation in this population. Previous studies in which CNS radiation was omitted showed an increase in CNS relapsed rates among boys but not girls, he pointed out.

“This does imply that in the more recent generation of T-lineage ALL treatment trials that we’ll need to monitor sex-based differences in outcome, as fewer and fewer patients with T-ALL disease received cranial radiation in these more recent trials and in contemporary therapy,” he said.

One possible mechanism for sex-based outcome differences might be differences in steroid metabolism, as suggested by the higher osteonecrosis rate among girls, he added.

In the question-and-answer following the presentation, William G. Woods, MD, from Emory University, Atlanta, asked what role testicular relapse played in outcomes.

Dr. Gupta replied that the investigators had considered that the excess risk for extramedullary relapse in boys might be accounted for by testicular relapse, but “when you take away testicular relapse from those numbers and really just concentrate on CNS, it’s still that substantial difference when you’re talking about B-lineage disease.”

In patients with T-ALL as well, CNS relapse was more common in boys after controlling for testicular relapse, he said.

Another audience member asked whether the data suggest a benefit to treating boys with CNS-penetrating drugs such as dexamethasone or high-dose methotrexate,

Dr. Gupta said that it’s still uncertain whether it is clinically sound to subject a boy with otherwise–standard-risk disease to more intensive high-risk therapy, given the relatively small absolute differences in outcomes between the sexes.

The study was supported by grants from the National Cancer Institute and the St. Baldrick’s Foundation. Dr. Gupta, Dr. Woods, and Dr. Meret had no relevant conflicts of interest to report.

“Vaccines have been the bright light of this extraordinary challenge that we’ve gone through,” said Anthony S. Fauci, MD, director of the National Institute of Allergy and Infectious Diseases.

In an address for the opening ceremony of the American Thoracic Society’s virtual international conference, Dr. Fauci emphasized the role of basic and clinical research and government support for science in helping turn the tide of the COVID-19 pandemic.

“A few weeks ago, I wrote an editorial in Science, because there was some misunderstanding about how and why we were able to go from a realization of a new pathogen in January of 2020, to getting doses of vaccines in the arms of individuals – a highly efficacious vaccine – 11 months later. Truly, an unprecedented accomplishment,” he said.

“But as I said in the editorial, the speed and efficiency with which these highly efficacious vaccines were developed, and their potential for saving millions of lives, are due to an extraordinary multidisciplinary effort, involving basic, preclinical, and clinical science that had been underway – out of the spotlight – for decades and decades before the unfolding of the COVID-19 pandemic, a fact that very few people really appreciate: namely, the importance of investment in biomedical research.”
 

The general addresses the troops

Perhaps no other audience is so well suited to receive Dr. Fauci’s speech as those who are currently attending (virtually) the ATS conference, including researchers who scrutinize the virus from every angle to describe its workings and identify its vulnerabilities, epidemiologists who study viral transmission and look for ways to thwart it, public health workers who fan out to communities across the country to push vaccine acceptance, and clinicians who specialize in critical care and pulmonary medicine, many of whom staff the respiratory floors and intensive care units where the most severely ill patients are treated.

Speaking about the lessons learned and challenges remaining from the COVID-19 pandemic, Dr. Fauci briefly reviewed the epidemiology, virology and transmission, diagnostics, and clinical course of SARS-CoV-2 infections and the therapeutics and vaccines for COVID-19.
 

Epidemiology

The pandemic began in December 2019 with recognition of a novel type of pneumonia in the Wuhan District of Central China, Dr. Fauci noted.

“Very quickly thereafter, in the first week of January 2020, the Chinese identified a new strain of coronavirus as [the] source of the outbreak. Fast forward to where we are right now: We have experienced and are experiencing the most devastating pandemic of a respiratory illness in the last 102 years, with already approximately 160 million individuals having been infected – and this is clearly a gross undercounting – and also 3.3 million deaths, again, very likely an undercounting,” he said.

According to the Centers for Disease Control and Prevention, as of May 9, 2021, there were approximately 32.5 million cases of COVID-19 and 578,520 deaths in the United States. Those cases and deaths occurred largely in three surges in the United States, in early spring, early summer, and late fall of 2020.
 

Virology and transmission

SARS-CoV-2 is a beta-coronavirus in the same subgenus as SARS-CoV-1 and some bat coronaviruses, Dr. Fauci explained. The viral genome is large, about 30,000 kilobases, and it has four structural proteins, most importantly the S or “spike” protein that allows the virus to attach to and fuse with cell membranes by binding to the ACE2 receptor on tissues in the upper and lower respiratory tract, gastrointestinal tract, cardiovascular system, and other organ systems.

The virus is transmitted mainly through exposure to respiratory droplets within 6 feet of an infected person, or sometimes through droplets or particles that remain in the air over time and various distances.

Contact with contaminated surfaces, once feared as a means of transmission, is now understood to be less common.

The virus has been detected in stool, blood, semen, and ocular secretions, although the role of transmission through these sources is still unknown.

“Some very interesting characteristics of this virus, really quite unique compared to other viruses, certainly other respiratory viruses, is [that] about a third to 40% of people who are infected never develop any symptoms,” Dr. Fauci said. “Importantly, and very problematic to what we do to contain it – particularly with regard to identification, isolation, and contract tracing – between 50% and 60% of the transmissions occur either from someone who will never develop symptoms, or someone in the presymptomatic phase of disease.”

The fundamentals of preventing acquisition and transmission are as familiar to most Americans now as the Pledge of Allegiance: universal mask wearing, physical distancing, avoiding crowds and congregate settings, preference for outdoor over indoor settings, and frequent hand washing, he noted.
 

Diagnostics

Tests for SARS-CoV-2 infection fall into three basic categories: molecular tests such as polymerase chain reaction (PCR) that are highly specific and highly sensitive for actual infections, antigen tests that detect the viral protein rather than the nucleic acids, and antibody tests to detect serum proteins made in response to viral infection.

Antigen testing is used largely for broader surveillance of groups of individuals to detect viral penetrance within that group, Dr. Fauci noted.
 

Clinical course

The clinical course of COVID-19 has some interesting characteristics but is not substantially different from a flu-like syndrome, Dr. Fauci said.

Symptoms and signs common to both types of infections include fever, cough, fatigue, anorexia, dyspnea, and myalgias, but the loss of smell and/or taste preceding the onset of respiratory symptoms is a unique feature of COVID-19.

Dr. Fauci cited data on more than 44,000 individuals with confirmed COVID-19 in China that showed that a large majority (81%) of cases were mild or moderate in nature, but 14% of patients experienced severe disease, and 5% were critically ill. The case-fatality rate in this study was 2.3%.

People at increased risk for severe disease include older adults and those of any age with certain comorbidities.

Manifestations of severe COVID-19 infections in adults can include neurological disorders, hyperinflammation, acute respiratory distress syndrome, cardiac dysfunction, hypercoagulability, and acute kidney injury.

In children, COVID-19 has been associated with a multisystem inflammatory syndrome (MIS-C) similar to Kawasaki disease.

In a substantial number of cases, the effects of COVID-19 can linger for 6 months or longer, Dr. Fauci said, pointing to a study from the University of Washington in Seattle.

Investigators there found that approximately 30% of patients enrolled at their center reported persistent symptoms for as long as 9 months after the initial illness, with fatigue as the most commonly reported symptom. One-third of outpatients with mild disease also reported persistent symptoms.
 

Therapeutics

Therapeutics that are either approved by the Food and Drug Administration, have emergency use authorization, or are in clinical trials for early or moderate disease include remdesivir (Veklury, Gilead Sciences), monoclonal antibodies, convalescent plasma, antiviral agents, hyperimmune globulin, anticoagulants, and immunomodulators.

Options for moderate to severe to advanced disease include dexamethasone, baricitinib (Olumiant, Eli Lilly and Company) plus remdesivir, and immunomodulators such as infliximab (Remicade, Janssen Biotech), and biosimilars.
 

Vaccines

Finally, Dr. Fauci reviewed the current state of vaccines, including the three with emergency use authorization from the FDA as of this writing: two nucleic acid, messenger RNA-based (mRNA) vaccines from Moderna and Pfizer/BioNTech, and an adenoviral vector-based vaccine from Johnson & Johnson.

Other vaccines in development or in use elsewhere in the world include recombinant protein and adjuvant approaches by GlaxoSmithKline and Sanofi (in a phase 2 clinical trial launched in February 2021) and by Novavax.

The three vaccines in use in the United States were highly efficacious in both clinical trials, with efficacy of about 95% for the mRNA vaccines and 67% for the Johnson & Johnson vaccine.

The real-world performance of these vaccines has been even more impressive, however.

For example, the Johnson & Johnson vaccine had 72% efficacy at preventing moderate to severe COVID 19 in the United States, 68% in Brazil, and 64% in South Africa, and 85% efficacy against severe disease across all regions studied, Dr. Fauci said.

He cited a study of 22,234 employees of the University of Texas Southwestern Medical Center in Dallas who were vaccinated under a program started on Dec. 15, 2020. The COVID-19 infection rate among these vaccinated employees was 0.05%.

Dr. Fauci recounted the experience in Israel, where the highly transmissible B.1.1.7 strain of SARS-CoV-2 is predominant. A chart of the progress shows clearly that as the vaccine doses delivered steadily increased, the number of COVID-19 cases began a precipitous decline.
 

Horse race

Fittingly for a speech presented on the day that the Preakness Stakes – the second leg in thoroughbred racing’s Triple Crown – was run, Dr. Fauci closed with a cartoon showing two racehorses, labeled “SARS-CoV-2” and “Vaccines,” nearly neck-and-neck, but with vaccines having a slight lead.

“We are in a race against the virus. The vaccines, and the virus: If we vaccinate the overwhelming proportion of our population, we will without a doubt be able to crush the outbreak in the same way as we have done with other viral-borne diseases like measles, smallpox, and polio.

“So, the message is: Get vaccinated,” he concluded.

You’ve successfully resected a skin cancer lesion, leaving clear margins. Now what?

That’s the question the authors of an evidence-based guideline on reconstruction after skin cancer resection set out to answer.

The guideline – a joint effort of the American Society of Plastic Surgeons, American Society for Dermatologic Surgery, American Academy of Dermatology, American Academy of Facial Plastic and Reconstructive Surgery, American Academy of Otolaryngology – Head and Neck Surgery Foundation, American College of Mohs Surgery, American Society for Mohs Surgery, and American Society of Ophthalmic Plastic and Reconstructive Surgery – was published online in the Journal of the American Academy of Dermatology.

From the outset, the panel members realized that to keep the guideline manageable they had to limit recommendations to the practice of reconstruction defined as “cutaneous closure that requires a flap, graft, or tissue rearrangement.”

Other wound closure methods, such as secondary intention healing; simple closures; and complex closures that do not involve flaps, grafts, muscle, or bone, were not covered in the recommendations.

As with similar guidelines, the developers selected seven clinical questions to be addressed, and attempted to find consensus through literature searches, appraisal of the evidence, grading of recommendations, peer review, and public comment.

“We had a very heterogeneous set of things that we were trying to comment on, so we had to keep things somewhat generic,” lead author Andrew Chen, MD, chief of the division of plastic surgery, at the University of Connecticut Health Center, Farmington, said in an interview.

“Skin cancer and reconstruction affect different body areas and areas of different sizes. When we were creating the guidelines, we had to tailor the questions we could ask based on things that would make sense to answer, because obviously we couldn’t ask a question such as: ‘What’s better, a skin graft or a flap?’ Well, there are some things you can’t put a skin graft on – it won’t last, so we couldn’t ask that kind of question,” Dr. Chen said.

Curtis Cetrulo, MD, a plastic and reconstructive surgeon at Massachusetts General Hospital, Boston, who was not involved in the guideline process, said in an interview that the broad recommendations are in keeping with his practice and experience. He also acknowledged, however, the difficulty in creating a guideline that covers the complexity and heterogeneity of reconstructive surgery.

“These are generally good recommendations, but they’re recommendations only, with generally weak levels of evidence. What we really need are clinical trials that can give us definitive answers to some of these questions,” he said.

Recommendations
 

The seven key recommendations, based on the clinical questions raised, are summarized below:

• Delayed (asynchronous) reconstruction is acceptable. Although the quality of the evidence is low and the recommendations are listed as an option, the guideline authors said that depending on the situation, reconstruction can be performed either immediately after resection or delayed by days, weeks, “or even months.”
• Systemic antibiotics should not be routinely prescribed in the interim between resection and reconstruction in adults. Here too, the evidence is low and the recommendation strength is weak, but in “the absence of data showing convincing benefits, systemic antibiotic therapy does not appear necessary or desirable in most cases when there is an interval between cancer resection and reconstruction,” the work group wrote.
• Clinicians may administer perioperative systemic antibiotics in a facility-based setting for adults undergoing reconstruction (3a), but antibiotics should not be routinely prescribed in an office-based setting (3b). The rationale for these recommendations, supported by a moderate level of evidence, is that the risk of surgical-site infection is generally higher in facilities, compared with an office-based setting. Patients who undergo reconstruction in hospitals or surgical centers are more likely to have complex reconstructions or have risks that may make them suitable candidates for antibiotics, but patients in office-based setting may often be spared from the additional costs, side effects, and possible drug interactions from antibiotic use. “There is no evidence in either setting that long-term antibiotic prophylaxis provides infection risk reduction, compared with short-term prophylaxis,” the guideline working group wrote.
• Continue anticoagulant, antithrombotic, and antiplatelet medications for adult patients undergoing reconstruction after skin cancer resection in the office-based setting (4a), and in the facility-based setting should coordinate with the physician managing anticoagulation before modifying the medication prior to surgery (4b). Evidence quality and recommendation strength are both moderate.
• The guideline authors recommend against routine prescription of narcotics as first-line treatment for pain in adults undergoing skin reconstruction (5a), favoring instead acetaminophen and NSAIDs as first-line therapy (5b). Evidence quality and recommendation strength are both moderate.
• In the absence of standardized protocols for the management of pain medications, oral antibiotics, and/or anticoagulants in the perioperative period, clinicians should discuss possible approaches with adult patients. “Educating patients about their perioperative treatment through discussion of treatment strategies may help alleviate anxiety, improve communication, increase patient satisfaction, and maximize patient compliance with the postoperative orders,” the guideline authors wrote.
• The authors suggest that adult patients may be offered follow-up assessments to discuss functional and cosmetic outcomes. “The return of the patient for follow-up visits is an excellent opportunity to better understand and measure these outcomes, improve patient-physician communication, and foster quality improvement. Postoperative follow-up can lead to increased communication between the patient and physician, thereby empowering patients to comment on satisfaction and other important outcomes measures,” they wrote.

What’s next

The guideline developers acknowledged that data are limited regarding reconstructive surgery following skin cancer resection, and that higher-quality studies would help to improve future guidelines. Dr. Chen said that greater use of prospective surgical databases and more systematic collection of patient-reported outcomes could inform further efforts.

The guideline development process was supported by the various groups represented. Dr. Chen and Dr. Cetrulo reported no relevant disclosures.

You’ve successfully resected a skin cancer lesion, leaving clear margins. Now what?

That’s the question the authors of an evidence-based guideline on reconstruction after skin cancer resection set out to answer.

The guideline – a joint effort of the American Society of Plastic Surgeons, American Society for Dermatologic Surgery, American Academy of Dermatology, American Academy of Facial Plastic and Reconstructive Surgery, American Academy of Otolaryngology – Head and Neck Surgery Foundation, American College of Mohs Surgery, American Society for Mohs Surgery, and American Society of Ophthalmic Plastic and Reconstructive Surgery – was published online in the Journal of the American Academy of Dermatology.

From the outset, the panel members realized that to keep the guideline manageable they had to limit recommendations to the practice of reconstruction defined as “cutaneous closure that requires a flap, graft, or tissue rearrangement.”

Other wound closure methods, such as secondary intention healing; simple closures; and complex closures that do not involve flaps, grafts, muscle, or bone, were not covered in the recommendations.

As with similar guidelines, the developers selected seven clinical questions to be addressed, and attempted to find consensus through literature searches, appraisal of the evidence, grading of recommendations, peer review, and public comment.
