Introduction

Febrile neutropenia (FN) is one of the most concerning complications associated with chemotherapy treatment, often leading to hospitalizations and delays in chemotherapy. The NCCN Guideline recommends primary prophylaxis with G-CSFs for patients receiving chemotherapy regimens that have an intermediate risk for FN if the patients have risk factors. A common intermediate risk for FN regimen is CHOP plus an anti-CD20 monoclonal antibody (mAb) for the treatment of non-Hodgkin’s lymphoma (NHL). At VASDHCS, an evaluation of the appropriate use of prophylactic GCSFs in this risk group would allow better optimization of patient care.

Objective

To evaluate the incidence of FN in correlation with the appropriate use of G-CSFs in patients who received CHOP plus an anti-CD20 mAb for the treatment of NHL

Methods

This is a retrospective study at VA San Diego of adult veterans with a confirmed diagnosis of NHL who received the first cycle of CHOP plus an anti- CD20 mAb between January 1, 2006, to October 1, 2021. Patients were categorized based on whether they received prophylactic G-CSF during the first cycle. The primary outcome measured was the incidence of FN in veterans with risk factor(s) who received CHOP plus an anti-CD20 mAb. The secondary outcome was the percentage of patients with risk factors who received G-CSF regardless of FN incidence. Primary outcome was analyzed using 2-tailed Fisher exact test.

Results

57 patients were included in the final analysis. In patients with at least one risk factor for FN, 26 (60%) received prophylactic G-CSF and 17 (40%) did not. There is 1 case of FN in the group that received G-CSF and 2 cases of FN in the group without G-CSF (RR, 0.33; P = .55; 95% CI, 0.03-3.33).

Conculsions

In patients receiving treatment for NHL with CHOP plus an anti-CD20 mAb, most of the patients with at least 1 risk factor for FN were initiated on G-CSF. Based on the results of the study, our veteran population does not appear to have an increased risk for FN without G-CSF. A larger study is warranted to further evaluate the significance of FN in correlation with prophylactic G-CSF.

Purpose

Ensuring that patients/families are engaged as partners in their health care is an effective way to measure the quality of patient care. Self-reported patient data, such as symptom burden, provides an accurate and effective way to measure patient-reported outcomes. Our team reviewed 20 patient charts, randomly, to assess for documentation of at least 3 or more domains of toxicities of immune checkpoint inhibitors. The baseline comprehensive documentation rate was 50%. Our goal is to improve the documentation rate to 80% for our first process improvement cycle.

Aim Statement

Increase documentation of 3 or more toxicities immune checkpoint inhibitors to a goal rate of 80%.

Methods

A free online patient monitoring checklist tool was printed and provided to patients receiving immune checkpoint inhibitors (on their infusion day) during the check-in process. The patients were instructed to complete the tool prior to the provider clinic visit, while in the waiting area. The completed tool was given to the provider on the day of their visit. Prior to the start of this Plan-Do-Study-Act (PDSA) cycle, all providers were “reminded”/ instructed to ensure documentation of 3 or more toxicities immune checkpoint inhibitors. The cycle lasted for 3 weeks. At the end of the 3 weeks, our team reviewed the charts of those patients.

Results

Documentation rate of 3 or more toxicities increased from 50% to 90%.

Conclusions

When completed patient monitoring tools were provided to the providers during the clinic visit, the providers increased their documentation rate of the toxicities. There is literature supporting improving patient satisfaction using self-reported symptoms monitoring tools. Also, given the burden of documentation and shorter visit times, providers found this to be an easy way to address patient symptoms. While electronic patient-reported outcome (e-PRO) tools are ideal for ongoing symptom monitoring, this is a simple way to address the same in low-resourced communities. For our next cycle, we plan on using patient feedback to improve the documentation form incorporating larger fonts for patients with low vision.

Background/Purpose

Tumor lysis syndrome (TLS) is caused by the release of intracellular products into the blood following rapid lysis of malignant cells resulting in hyperuricemia, hyperkalemia, hyperphosphatemia, and hypocalcemia. Complications of TLS include acute renal failure, cardiac arrhythmias, seizure, and sudden death. Allopurinol is commonly initiated as prophylaxis for patients at risk for TLS to prevent buildup of uric acid and decrease the incidence of obstructive uropathy caused by uric acid precipitation. Allopurinol takes several days to reduce uric acid levels, therefore it is recommended to initiate allopurinol 1 to 2 days prior to the start of chemotherapy and continue until the risk of TLS has ceased, usually within 7 days of chemotherapy initiation. Unnecessarily continuing allopurinol beyond 10 days increases the risk of adverse events, including allergic skin rashes and myelosuppression. A report of allopurinol orders for TLS from March 1, 2020, to March 31, 2021 was generated. Of these orders, there were 44 unique patients and 56 total allopurinol courses. The median duration of allopurinol for TLS was 39 days, with a duration of allopurinol of 10 days or less in 10 (18.2%) cases.

Methods

On September 16, 2021, inpatient prescribing of new allopurinol orders was restricted to an inpatient order menu with quick orders designating an indication of gout or TLS in the comment section. The TLS quick order was defaulted to a dose of 300 mg for 10 days. Education was also provided to the medical staff. Descriptive statistics were used.

Results

Since implementation of the allopurinol order menu, 17 patients with cancer have initiated allopurinol for TLS. The menu was used in 14 (82.4%) patients. The median duration of allopurinol was 8 days and 11 (64.7%) allopurinol courses were 10 days or less. The main reasons for not using the allopurinol menu were due to dose reduction of allopurinol due to renal dysfunction or the primary hematologist/oncologist ordering outpatient allopurinol prior to admission for chemotherapy.

Implications

The introduction of an inpatient allopurinol order menu has decreased excessive allopurinol therapy when utilized for TLS. This has resulted in decreased pill burden, adverse events, and cost.

Purpose

To evaluate the impact that a pharmacistmanaged oral anticancer clinic has on patient adherence to oral anticancer therapy in regard to medication adherence and adherence to lab monitoring.

Background

Oral anticancer therapy is typically preconceived to be safer than intravenous. However, these medications have a narrow therapeutic window and significant toxicities, requiring close monitoring to ensure patient safety. Previous studies have shown that pharmacist-led oral anticancer clinics have improved adherence and decreased toxicity.

Methods

A retrospective chart review was completed for patients prescribed abiraterone, enzalutamide, or ibrutinib. The primary outcome assessed medication adherence by comparing the medication possession ratio (MPR) before (phase 1) and after (phase 2) the initiation of the pharmacist-led oral anticancer therapy clinic. The secondary outcome assessed lab monitoring adherence by patients and providers in phase 1 vs. phase 2. This study also examined descriptive outcomes in phase 2.

Data Analysis

Independent sample t tests were used to analyze primary and secondary endpoints. For descriptive endpoints, standard deviations and range of scores were assessed for continuous variables.

Results

A statistically significant increase in the mean MPR ratio was shown between phase 1 vs phase 2 (0.98 vs 1.05; P = .027). For patient adherence to lab monitoring, there was a statistically significant improvement for patients on abiraterone (21.9% vs. 67%; P < .001) and enzalutamide (35.7% vs 90.5%; P = .006). There was a decline in lab monitoring adherence for patient on ibrutinib but this effect was not statistically significant (56.2% vs. 51%; P = .283). Similar results were shown for provider adherence to lab monitoring. Descriptive outcomes showed that the pharmacist had on average 6.7 encounters per patient.

Conclusions/Implications

A pharmacist-led oral anticancer clinic can improve MPR ratios and patient adherence to oral anticancer regimens. Patient and provider lab monitoring adherence was improved for abiraterone and enzalutamide. Improvement in patient/ provider lab monitoring adherence for ibrutinib was not shown, possibly due to the impact of the COVID-19 pandemic, small sample size, and retrospective nature of this study. The results of this study supports that overall, a pharmacist-led oral anticancer clinic can significantly improve patient outcomes, which aligns with previous smaller studies.

Background

The VA Outpatient Chemotherapy Clinic sees approximately 870 veterans each year. Of these, 5% receive home-infusion chemotherapy. COVID-19 created staffing challenges for the contracted homeinfusion company utilized by the VA for home-infusion chemotherapy. The VA developed a self-contained home-infusion program for 5-FU to ensure needed care could be delivered to veterans without delay.

Methods

After researching private sector and VA models of providing home-infusion chemotherapy services, analyzing literature, internal VA patient safety data, and financial implications of different home-infusion pump options, including both CADD pumps and elastomeric pumps, CADD pumps were determined to be the best financial option and safest option for providing home-infusion 5-FU through the VA. Patient education documents were created from CADD pump user manuals and literature. 

Results

A home-infusion program for 5-FU chemotherapy was implemented at the VA Outpatient Chemotherapy Clinic in March 2022. Veterans receive a home-infusion pump, 5-FU, education, and access to a 24-hour telephone support line staffed by an oncology registered nurse through the VA. Patient education consists of home-infusion pump training, implanted port de-accessing, chemotherapy spill management, and hazardous waste disposal.

Conclusion

Ten veterans have started their home-infusion portion of therapy through the VA, amounting to 34 completed cycles, between March 2022 and June 2022. This program is completely self-contained within the VA Outpatient Chemotherapy Clinic. It has allowed for initiation and continuation of needed chemotherapy regimens in an environment of staffing instability at the contracted home-infusion company. The home-infusion program required the acquisition of home-infusion pumps and supplies. The home-infusion pumps can be reused by another patient after completion of treatment making this program sustainable. Existing VA medical oncology staffing was utilized with the additional need for oncology nurses to take calls to provide 24-hour telephone support for any pumprelated issues that may arise during home-infusion therapy. A VA home-infusion program allows for veterans to receive seamless cancer care through one entity. This program is replicable at other VAs and can be expanded to include other forms of home-infusion therapy, such as antibiotics.

Background

Currently, within the Veterans Affairs Healthcare System, anticancer therapy infusions and injections are primarily offered at VA medical centers (VAMCs) in urban areas. The time and out-of-pocket expenses related to travel present a barrier to care, often leading veterans to seek cancer care in the community. The Minneapolis VA developed a “Remote Infusion” program that deploys a chemotherapy certified RN to administer anticancer and supportive therapies at surrounding Community Based Outpatient Clinics (CBOCs). The program expanded in October 2021, and since, they have provided 259 infusions and injections to 145 veterans at 16 CBOCs. These efforts have saved at least 20,000 miles of travel for veterans in the Minneapolis/ St. Cloud catchment area. Building off the success of this program, the National Oncology Program Integrated Project Team has developed the “Close to Me” CBOC Infusion Program.

Methods

The “Close to Me” CBOC Infusion Program utilizes VAMCs to compound treatments. Then a chemotherapy certified RN is deployed to the surrounding CBOCs to administer treatments. Veterans eligible for this program must have received and tolerated their first dose of treatment at a VAMC. Medications included in this program have low risk of reaction, short infusion time, and at least 8 hours of drug stability. Treatments include immune check point inhibitors, leuprolide, octreotide, IV fluids, and iron infusions. Additional treatments continue to be evaluated and added. Telehealth modalities are utilized for patient visits with their oncology provider for treatment clearance. An implementation toolkit, including a library of standard operating procedures, note templates, and staffing models, has been developed for VAMCs interested in replicating this program.

Results

The Pittsburgh VAMC launched the first “Close to Me” CBOC Infusion Program June 8, 2022.

Conclusions

 The “Close to Me” CBOC infusion program optimizes current VA infrastructure and processes to expand access to the world class oncology care VA provides by reducing travel burden for the veterans. Additional areas of novel solutions under development to provide expanded access points to anticancer therapies include mobile infusion units, mobile compounding units, and home administration.

Background

Currently, within the Veterans Affairs Healthcare System, anticancer therapy infusions and injections are primarily offered at VA medical centers (VAMCs) in urban areas. The time and out-of-pocket expenses related to travel present a barrier to care, often leading veterans to seek cancer care in the community. The Minneapolis VA developed a “Remote Infusion” program that deploys a chemotherapy certified RN to administer anticancer and supportive therapies at surrounding Community Based Outpatient Clinics (CBOCs). The program expanded in October 2021, and since, they have provided 259 infusions and injections to 145 veterans at 16 CBOCs. These efforts have saved at least 20,000 miles of travel for veterans in the Minneapolis/ St. Cloud catchment area. Building off the success of this program, the National Oncology Program Integrated Project Team has developed the “Close to Me” CBOC Infusion Program.

Methods

The “Close to Me” CBOC Infusion Program utilizes VAMCs to compound treatments. Then a chemotherapy certified RN is deployed to the surrounding CBOCs to administer treatments.

In the PD-L1 CPS ≥ 1 subgroup, however, no significant OS benefit was observed (median OS 17.6 months vs 16.0 months; HR 0.86; 95% CI 0.72-1.04; P = .1125). Additionally, in an exploratory analysis, the addition of pembrolizumab showed consistent OS benefit among patients whose tumors express PD-L1 with a CPS of 10-19 and CPS ≥ 20. The updated progression-free survival (PFS) and objective response rates (ORR) were consistent with prior interim data. No new safety signals were observed after the longer follow-up.

These data confirm that pembrolizumab plus chemotherapy should remain the first-line treatment for patients with advanced or metastatic TNBC whose tumors express PD-L1 with a CPS of ≥ 10. The treatment of metastatic TNBC with low or negative PD-L1 CPS scores remains an area of unmet clinical need, and further research is needed to explore better options for these patients.

Wang and colleagues presented results from a randomized, phase 3 trial comparing first-line nab-paclitaxel plus cisplatin (AP) with gemcitabine plus cisplatin (GP) among 254 patients with previously untreated metastatic TNBC. Median PFS (mPFS) was 9.8 months with AP vs 7.4 months with GP (HR 0.67; 95% CI 0.50-0.88; P  =  .004). Furthermore, AP had significantly higher ORR compared with GP (81.1% vs 56.3%; P  <  .001) and significantly improved median OS (26.3 months vs 22.9 months; HR 0.62; 95% CI 0.44-0.90; P  =  .010).

In the exploratory analyses of PFS by stratification factors, the mPFS was significantly longer in the AP group compared with the GP group in the majority of subgroups, except for those patients who presented with de novo stage IV disease or a disease-free interval of < 1 year. Regarding safety data, a significantly higher incidence of grade ≥ 3 neuropathy (19% vs 0%) and nausea and vomiting (6% vs 1%) was noted in the AP group compared with the GP group, while grade ≥ 3 thrombocytopenia was more common in the GP group compared with the AP group (29.4% vs 3.9%).

The AP doublet achieved superior efficacy with a manageable safety profile, compared with GP in patients with previously untreated metastatic TNBC. It is not clear, however, whether the AP doublet is superior to single-agent therapy in this setting, especially given several prior studies that showed no survival benefit and increased toxicity from combination therapy compared with sequential single-agent therapy in metastatic breast cancer. More studies are needed to establish the role of the AP doublet in combination with pembrolizumab in this cohort of patients, given that first-line pembrolizumab plus chemotherapy is considered the standard of care for patients with metastatic TNBC whose tumors express PD-L1.

Rugo and colleagues presented results from a randomized phase 3 study comparing 205 mg/m²oral paclitaxel plus 15 mg encequidar (a novel P-glycoprotein pump inhibitor that allows oral absorption of paclitaxel) on 3 consecutive days per week vs 175 mg/m² intravenous paclitaxel once every 3 weeks. The study enrolled 402 postmenopausal women from Latin America with metastatic breast cancer who were at least 1 year from their last taxane therapy. Oral paclitaxel plus encequidar (oPac + E) increased the confirmed tumor response compared with intravenous paclitaxel (IVpac) (36% vs 23%; P = .01). There was a trend toward improved PFS (8.4 vs 7.4 months; HR 0.768; 95.5% CI 0.584-1.01; P = .046) and OS (22.7 vs 16.5 months; HR 0.794; 95.5% CI 0.607-1.037; P = .08) with oPac + E compared to IVpac, respectively. Grade ≥3 adverse events were comparable with oPac + E and IVpac (55% vs 53%), although a lower incidence of grade 3 neuropathy (2% vs 15%) and alopecia (49% vs 62%) was noted with oPac + E compared with IVpac. A higher incidence of grade ≥ 3 gastrointestinal toxicity (nausea, vomiting, and diarrhea) and grade 4 neutropenic complications was noted in the oPac + E group. Patients with elevated baseline liver enzymes were particularly susceptible to early neutropenia and serious infections.

This study demonstrates that oral paclitaxel can be a possible alternative treatment option to intravenous paclitaxel in a select group of patients with metastatic breast cancer. High-grade neutropenia appears to be a major treatment-limiting toxicity with oPac + E. Therefore, careful patient selection and close monitoring are crucial for the successful management of this adverse event.

In the PD-L1 CPS ≥ 1 subgroup, however, no significant OS benefit was observed (median OS 17.6 months vs 16.0 months; HR 0.86; 95% CI 0.72-1.04; P = .1125).

Individuals with type A blood have a 16% higher risk for early onset stroke (EOS) than those with other blood types, new research shows.

Conversely, results from a meta-analysis of nearly 17,000 cases of ischemic stroke in adults younger than 60 years showed that having type O blood reduced the risk for EOS by 12%.

In addition, the associations with risk were significantly stronger in EOS than in those with late-onset stroke (LOS), pointing to a stronger role for prothrombotic factors in younger patients, the researchers noted.

“What this is telling us is that maybe what makes you susceptible to stroke as a young adult is the blood type, which is really giving you a much higher risk of clotting and stroke compared to later onset,” coinvestigator Braxton Mitchell, PhD, professor of medicine and epidemiology and public health at the University of Maryland, Baltimore, said in an interview.

The findings were published online in Neurology.
 

Strong association

The genome-wide association study (GWAS) was done as part of the Genetics of Early Onset Ischemic Stroke Consortium, a collaboration of 48 different studies across North America, Europe, Japan, Pakistan, and Australia. It assessed early onset ischemic stroke in patients aged 18-59 years.

Researchers included data from 16,927 patients with stroke. Of these, 5,825 had a stroke before age 60, defined as early onset. GWAS results were also examined for nearly 600,000 individuals without stroke.

Results showed two genetic variants tied to blood types A and O emerged as highly associated with risk for early stroke.

Researchers found that the protective effects of type O were significantly stronger with EOS vs. LOS (odds ratio [OR], 0.88 vs. 0.96, respectively; P = .001). Likewise, the association between type A and increased EOS risk was significantly stronger than that found in LOS (OR, 1.16 vs. 1.05; P = .005).

Using polygenic risk scores, the investigators also found that the greater genetic risk for venous thromboembolism, another prothrombotic condition, was more strongly associated with EOS compared with LOS (P = .008).

Previous studies have shown a link between stroke risk and variants of the ABO gene, which determines blood type. The new analysis suggests that type A and O gene variants represent nearly all of those genetically linked with early stroke, the researchers noted.

While the findings point to blood type as a risk factor for stroke in younger people, Dr. Mitchell cautions that “at the moment, blood group does not have implications for preventive care.”

“The risk of stroke due to blood type is smaller than other risk factors that we know about, like smoking and hypertension,” he said. “I would be much more worried about these other risk factors, especially because those may be modifiable.”

He noted the next step in the study is to assess how blood type interacts with other known risk factors to raise stroke risk.

“There may be a subset of people where, if you have blood type A and you have some of these other risk factors, it’s possible that you may be at particularly high risk,” Dr. Mitchell said.
 

More research needed on younger patients

In an accompanying editorial, Jennifer Juhl Majersik, MD, associate professor of neurology at the University of Utah, Salt Lake City, and Paul Lacaze, PhD, associate professor and head of the public health genomics program at Monash University, Australia, noted that the study fills a gap in stroke research, which often focuses mostly on older individuals.

“In approximately 40% of people with EOS, the stroke is cryptogenic, and there is scant data from clinical trials to guide the selection of preventative strategies in this population, as people with EOS are often excluded from trials,” Dr. Majersik and Dr. Lacaze wrote.

“This work has deepened our understanding of EOS pathophysiology,” they added.

The editorialists noted that future research can build on the results from this analysis, “with the goal of a more precise understanding of stroke pathophysiology, leading to targeted preventative treatments for EOS and a reduction in disability in patients’ most productive years.”

Dr. Mitchell echoed the call for greater inclusion of young patients with stroke in clinical trials.

“As we’re learning, stroke in older folks isn’t the same as stroke in younger people,” he said. “There are many shared risk factors but there are also some that are different ... so there really is a need to include younger people.”
