Richards and colleagues explored the effects of aspirin prophylaxis in women with chronic hypertension. They did not detect a lowered risk for preeclampsia but did note a significantly decreased risk for preterm birth in the aspirin group. This was a systematic review and meta-analysis of nine studies (including retrospective cohort and randomized controlled trials). The mixed quality of the source data did limit the meta-analysis. However, this finding suggests that further research is warranted, and we may have a new role for aspirin in helping to decrease preterm birth in women with chronic hypertension.

Cleary and colleagues investigated the use of 30 mg oral nifedipine ER given every 24 hours until delivery in patients with preE with SF. In this randomized, triple-blinded, placebo-controlled trial, 110 patients were randomly assigned to nifedipine treatment or placebo. The results suggest a role for this medication early in the treatment of preE with SF, as the treated patients were much less likely to require acute therapy for severe-range blood pressure. The researchers also noted a trend toward fewer cesarean deliveries (20.8% vs 34.7%) and lower neonatal intensive care unit admissions (29.1% vs 47.1%) in the nifedipine ER group. This favors the use of nifedipine ER in patients with preE with SF.

Stewart and colleagues examined the more common morbidities associated with MTOP after 20 weeks estimated gestational age using a 10-year retrospective cohort study involving 407 patients. They found that 99% of the women had a successful vaginal delivery; however, 25% had some morbidity. Additionally, 16% of the women needed manual removal of placental tissue, 11% had postpartum hemorrhage, and 1.3% experienced severe maternal morbidity (including amniotic fluid embolism), but no maternal deaths occurred. Increased surveillance for postpartum hemorrhage in this patient population should be considered.

Righini and colleagues provide reassurance regarding a commonly used test to rule out pulmonary embolism in pregnant women. They present ancillary data from a prospective management outcome study of 149 women who underwent CT pulmonary angiography testing in pregnancy. There have been concerns raised regarding potential harmful effects related to intravenous iodinated contrast agents on thyroid function. None of the infants born to these patients had evidence of neonatal hypothyroidism (assessed via thyroid-stimulating hormone measurements). This gives reassurance that the use of CT pulmonary angiography testing for pulmonary embolism in pregnancy is safe.

A total of 126 patients were included in the full analysis set; median progression-free survival (PFS) was 18.8 months, overall response rate was 64.3%, and the safety profile was similar to prior studies. The median PFS in this observational study was comparable to a median PFS of 16.9 months in the CLEOPTRA study among 88 patients with prior (neo)adjuvant trastuzumab. HELENA also demonstrated similar PFS results for the hormone receptor (HR)-negative and HR-positive (HR+) subgroups (19.4 months vs 18.2 months), as well as for patients with nonvisceral and visceral metastases (20.5 months vs 18.0 months). These findings provide further support for use of the THP regimen as first-line treatment in the real-world setting for patients with HER2+ MBC and prior receipt of trastuzumab.

Adjuvant endocrine therapy (ET) is associated with a survival benefit for early-stage HR+ breast cancer; however, the absolute degree of benefit depends on various clinicopathologic features.² Although it generally has a manageable toxicity profile, some side effects carry more significant consequences (thromboembolism, endometrial carcinoma, osteoporosis), and some of the more common ones can affect routine quality of life (hot flashes, vaginal dryness, arthralgia).

A retrospective observational study including 5545 patients with pT1a-b estrogen receptor-positive (ER+) breast cancer demonstrated improvements in disease-free survival (DFS) and recurrence-free survival (RFS) among those who received ET vs those who did not receive ET after 5 and 7 years of follow-up (DFS: increases of 2.5% and 3.3%; RFS: increases of 1.9% and 4.3%) (Houvenaeghel et al). Among all patients, absence of ET was associated with decreased DFS (hazard ratio [HR] 1.275; P = .047) but no difference in RFS or OS. Patients with pT1a-b ER+ grade 2-3 tumors (n = 2363) experienced decreased DFS (HR 1.502, P = .049) without ET; however, those with pT1a-b ER+ grade 1 tumors did not experience a negative effect on DFS without ET.

These results provide further support for the survival improvements seen with adjuvant ET — although the relative benefit may be fairly modest — and that ET omission is a relevant consideration in patients with comorbidities or tolerance issues, particularly those with pT1a-b grade 1 tumors.

Advancements in breast cancer therapies have led to improvements in survival outcomes, and it is therefore increasingly essential to recognize risks for other cancer types in breast cancer survivors. Male breast cancer is rare, and although clinical management for the most part mirrors that of female breast cancer, it is important to be aware of potential differences in this population, including risks for subsequent non-breast primary cancers.³

A meta-analysis including eight retrospective cohort studies with male breast cancer survivors reported the standardized incidence ratio (SIR), which compares the incidence of non-breast second primary cancers (SPC) among men with first primary breast cancer vs the expected incidence of non-breast primary cancers in the general male population. The summary SIR estimate was 1.27 (95% CI 1.03-1.56), with increased risk for certain SPCs: colorectal (SIR 1.29; 95% CI 1.03-1.61), pancreatic (SIR 1.64; 95% CI 1.05-2.55), and thyroid (SIR 5.58; 95% CI 1.04-30.05) (Allen et al). Additionally, men diagnosed with breast cancer before 50 years of age were observed to have increased SPC risk compared with men who were older than 50 years at breast cancer onset (SIR 1.50 vs 1.14; P = .040).

This study highlights the importance of genetic assessment for men diagnosed with breast cancer, so they can be appropriately counseled on subsequent cancer risk. It also stimulates thinking regarding other potential contributing factors to the observed increased SPC risk among male breast cancer survivors, including the effect of various treatments, hormonal influences, and significant family history.

Studies have shown that older women derive a survival benefit with adjuvant chemotherapy; however, they may be at increased risk of experiencing toxicities owing to physical functioning and comorbidities.⁴ A comprehensive geriatric assessment is key, and it is also beneficial for identifying which patients have a higher likelihood of clinical decline after chemotherapy.

A prospective study including 295 robust women age ≥ 65 years with stage I-III breast cancer treated with chemotherapy showed that 26% had a chemotherapy-induced decline in frailty status; patients with high interleukin-6 (IL-6) and C-reactive protein (CRP) inflammatory markers before chemotherapy had a more than threefold odds of experiencing a chemotherapy-induced decline in frailty compared with those with low IL-6 and CRP (odds ratio 3.52; 95% CI 1.55-8.01; P = .003) (Ji et al).

These findings support the relationship between inflammation, aging, and chemotherapy-induced functional decline. Further research is warranted to identify whether there are specific drugs that are implicated, methods to enhance anti-inflammatory effects, and any downstream effect on breast cancer outcomes of these patients.

Still, some patients seek alternative or adjunctive treatment approaches, owing to a desire to identify the root cause of disease, their aversion toward Western medicine, or fear of adverse events. Yepes-Nuñez and colleagues performed a systematic review and meta-analysis including 23 studies of benefits and harms of allergen immunotherapy for AD. I had the privilege of participating in this study and can testify to the astronomical amount of work that went into comprehensively identifying all of the relevant studies and synthesizing the data. We found that adjunctive subcutaneous or sublingual allergen immunotherapy, particularly for house dust mites, led to modest but generally delayed improvements of AD severity, itch, and quality of life, and less definitive effects on sleep disturbance and AD flares. Overall, both were well tolerated, though subcutaneous immunotherapy was associated with more adverse events than sublingual immunotherapy. Allergen immunotherapy requires a significant investment of time by patients and was only modestly effective. Nevertheless, it may be a reasonable approach to consider in select patients with AD.

Benjamin Franklin famously stated that "an ounce of prevention is worth a pound of cure." Likewise, while successful treatment of AD is great, how can we advise patients and caregivers of children who are at high risk for AD? To answer this question, Voigt and Lele performed a systematic review and meta-analysis of 11 randomized controlled trials examining the efficacy of Lactobacillus rhamnosus at preventing AD in children when taken by mothers during pregnancy. They found that L. rhamnosus significantly reduced the risk of developing AD within 2 years, marginally significantly reduced risk at 4-5 years, and significantly reduced risk at 6-7 years, but no significant risk differences were observed at 10-11 years. The authors concluded that use of L. rhamnosus with or without other probiotics during pregnancy reduces the incidence of childhood AD at least up to age 7 years.

Wang and colleagues conducted an observational study of the relationship of home environment exposures with atopic disease, including AD, in 17,881 offspring from Iceland, Norway, Sweden, Denmark, and Estonia who had undergone two follow-up investigations every 10 years. They found that AD was associated with parent-reported visible mold and dampness/mold at home, living in an apartment, and living in newer buildings. Avoidance of these environmental exposures could possibly decrease the risk of developing AD, although future confirmatory studies are needed.

For each of these treatment/prevention approaches, the magnitude of benefit is not very large. Thus, these approaches do not replace our armamentarium of treatments and avoidance strategies for AD. Rather, they can be used complementarily as low-risk add-on interventions with a potential upside.

For each of these treatment/prevention approaches, the magnitude of benefit is not very large. Thus, these approaches do not replace our armamentarium of treatments and avoidance strategies for AD. Rather, they can be used complementarily as low-risk add-on interventions with a potential upside.

The phase 2 FIGHT trial¹ evaluated the role of bemarituzumab, an anti-FGFR2 antibody, in combination with chemotherapy during first-line treatment of advanced gastroesophageal adenocarcinoma. The primary endpoint of this trial was progression-free survival (PFS). This trial enrolled 155 patients with upper gastrointestinal tumors with FGFR2b overexpression (defined as at least 2+ by immunohistochemistry) or amplification on next-generation sequencing. About 30% of patients with HER2 nonpositive tumors (ie, those that would not qualify for treatment with the targeted agent trastuzumab) were eligible for participation. In the FIGHT trial, patients were randomized in a 1:1 ratio to receive either standard chemotherapy (folinic acid, fluorouracil, and oxaliplatin [FOLFOX]) or chemotherapy plus bemarituzumab. Patients in the experimental group were allowed to receive one dose of standard FOLFOX chemotherapy while biomarker testing was ongoing.

With a median follow-up time of 10.9 moths, PFS was numerically prolonged in the bemarituzumab group (9.5 vs 7.4 months), but it did not reach statistical significance (P = .073). Overall survival (OS) was improved in the experimental group (not reached vs 12.9 months; P = .027). With a longer follow-up of 12.5 months, in post hoc exploratory analysis, OS was significantly longer in the experimental group (19.2 vs 13.5 months; hazard ratio 0.60, P = .027). The rate of serious adverse events was similar between the two groups. However, it is important to note ocular toxicities associated with bemarituzumab treatment. Corneal adverse events were seen in 67% of patients in the experimental group, with 24% of patients experiencing grade 3 events. Moreover, 26% of patients discontinued bemarituzumab because of corneal adverse events.

Overall, this phase 2 trial demonstrated that FGFR2b is emerging as an important biomarker and target in patients with advanced gastroesophageal adenocarcinoma. Ongoing phase 3 trials (FORTITUDE-101 with FOLFOX [NCT05052801] and FORTITUDE-102 with FOLFOX and nivolumab [NCT05111626]) hopefully will confirm the early results seen in the FIGHT trial. Awareness and early attention to treatment-associated toxicities will be critical for the potential future incorporation of bemarituzumab into clinical practice.

A study by Ramos‐Santillan and colleagues explored whether the order of treatment modalities matter in the management of early-stage gastric cancer. Typically, perioperative chemotherapy (both neoadjuvant and adjuvant) is used during treatment of early-stage gastric cancer, which is usually defined as at least cT2N0 or cTxN+ disease. In this study, multivariable Cox regression analyses were performed on propensity score-matched cohorts. The study analyzed outcomes of 11,984 patients who were identified using the US National Cancer Database and treated between 2005 and 2014. The results revealed that patients who had stage I disease had better outcomes with upfront resection followed by adjuvant therapy. Patients with stage III disease did better with a neoadjuvant approach, whereas patients with stage II disease had similar outcomes regardless of chemotherapy timing. This research has the limitations inherent to the retrospective nature of the analysis and lack of prospective enrollment and controls. However, it does suggest that there may be a fraction of patients who should be treated with upfront resection. For incorporation of this change into standard practice, the question of therapy sequencing should be answered in a randomized prospective trial that incorporates the most updated systemic therapy (fluorouracil, leucovorin, oxaliplatin, and docetaxel [FLOT]) into its design.

Chemotherapy continues to play a critical role during first-line treatment of advanced esophageal and gastric adenocarcinoma. Triple chemotherapy regimens have been known to have increased efficacy in this setting, but their use has been limited by associated toxicities. A study by Nguyen and colleagues evaluated the TCX regimen (paclitaxel, carboplatin, and capecitabine) during first-line treatment of advanced gastric cancer. This regimen is similar to other triple chemotherapy regimens, such as FLOT and DCF (docetaxel, cisplatin, and fluorouracil), which have proven activity in this disease. This prospective phase 2 trial enrolled 83 patients. The median PFS (9.3 months) and OS (17 months) compared favorably with historical references. The regimen had expected adverse events, with cytopenias and fatigue being the most frequently reported. On the basis of the reported safety and efficacy, TCX has potential to be used as a chemotherapy backbone in future trials, but larger trials are needed to confirm the phase 2 trial results.

Once again, I have been given the distinct honor of analyzing two of the most provocative studies in colorectal cancer this month for Clinical Edge. The first study I will examine was done by Khamzina and colleagues and attempts to define the optimal time to perform surgery after neoadjuvant chemoradiotherapy in locally advanced rectal cancer. In this retrospective analysis, 770 patients who received long-course chemoradiotherapy for rectal cancer followed by total mesorectal excision (TME) were analyzed by how long the interval was between completion of radiation and surgery. Patients were separated into two groups: 6-8 weeks (n = 502) vs >8 weeks (n = 268). Though the pathologic complete response rates and 5-year disease-free survival rates were not significantly different between the two groups, tumor regression grade was significantly better in the >8 weeks arm (P = .004). This result confirms many previous studies that demonstrate continued tumor shrinkage months after completion of chemoradiotherapy and may provide an explanation of why the OPRA trial demonstrated a higher TME-free rate in the chemoradiotherapy-then-chemotherapy arm than it did in the induction chemotherapy-then-chemoradiotherapy arm (53% vs 41%).

Schaefer and colleagues looked at the potential prognostic markers for efficacy of transarterial radioembolization (TARE) with ⁹⁰Y resin microspheres in the treatment of liver-dominant metastatic colorectal cancer (mCRC). Their study evaluated 237 patients with liver-dominant mCRC from the prospective observational CIRSE Registry for SIR-Spheres Therapy (CIRT) study who were scheduled to receive TARE with ⁹⁰Y resin microspheres. For these patients, the aspartate transaminase-to-platelet ratio index (APRI), international normalized ratio (INR), and albumin-bilirubin (ALBI) grade were measured prior to treatment to potentially detect values that might be associated with differential outcomes from TARE. An APRI > 0.40 independently predicted worse overall survival (OS) (hazard ratio [HR] 2.25; P < .0001), progression-free survival (PFS) (HR 1.42; P = .0416), and hepatic PFS (HR 1.50; P = .0207). The other independent predictors for worse OS and hepatic PFS were an INR value of < 1 (HR 1.66; P = .0091) and ALBI grade 3 (HR 5.29; P = .0075), respectively. It is very difficult to make much out of this study save to say that poorer liver function at baseline (at least with respect to APRI and ALBI) predicts worse outcomes after TARE, which is none too controversial an opinion. That said, APRI and ALBI may be able to provide an extra measure of granularity to determine who might be more of a marginal candidate for TARE than would categorization according to Child-Pugh score alone. Saving these patients from a potentially morbid procedure would be a significant benefit.

Multiple studies have emphasized the potential for severe COVID-19 outcomes in patients with rheumatic disease, including patients with rheumatoid arthritis (RA). Because these studies often group together patients with different diseases, medications, and manifestations, differences in outcomes between patients with these conditions may be difficult to tease out.

Figueroa-Parra and colleagues performed a retrospective cohort study comparing people with RA who developed COVID-19 to those who did not have RA to examine the effect of RA characteristics, such as interstitial lung disease (ILD), serostatus, and bone erosions, on COVID-19 outcomes. Patients with RA, particularly those with seropositive RA, bone erosions, and RA-associated ILD, had approximately twofold (or higher) risk for severe COVID-19 outcomes, such as mortality or mechanical ventilation, than did those without RA. However, there was no difference in outcomes seen between patients with RA who were seropositive compared with those who were seronegative, with or without bone erosions, or with or without ILD. The mechanism by which RA phenotypes and their treatment affect this risk remains unclear.

Li and colleagues also looked at COVID-19 outcomes in patients with RA according to vaccination status using a UK primary care database. Among unvaccinated patients, the risk for SARS-CoV-2 infection and hospitalization or mortality because of COVID-19 were modestly higher in people with RA. Among vaccinated patients, there was no increased risk for breakthrough infection, COVID-19 hospitalization, or mortality observed in patients with RA over 3 or 6 months of follow-up, with a slight increase over 9 months of follow-up. Overall, both studies support prior research suggesting a higher risk for more severe COVID-19 in patients with RA, as well as potential mitigation with vaccination.

Predictors of RA course and severity are of great interest in determining the optimal therapy to reduce joint damage and prevent RA progression while also minimizing the adverse effects of treatment. Early disease course has been shown to be important in several studies. Giollo and colleagues compared patients with "difficult-to-treat RA," ie, RA that is resistant to multiple biologic disease-modifying antirheumatic drugs (bDMARD) or targeted synthetic DMARD (tsDMARD), with those without in an inception cohort study and found that early difficult management as well as delay of methotrexate initiation was associated with persistent inflammatory symptoms. This finding does not show a causative relationship between methotrexate and protection from the development of refractory RA but does lend support for early aggressive treatment in patients with a high inflammatory burden.

Conversely, Parisi and colleagues performed a subanalysis of the STARTER study of patients with RA in clinical remission to evaluate the impact of different therapies. The STARTER study had shown an association between ultrasound detection of tenosynovitis and RA flares. Of the more than 250 patients completing the study, ultrasound evidence of tenosynovitis was better controlled in patients on combination bDMARD and conventional synthetic DMARD (csDMARD) therapy than in those on csDMARDs monotherapy, with a trend toward reduction in flares in patients on combination therapy. Given the relatively small effect, it is not clear that combination therapy is associated with deeper remission, but, as suggested in prior studies, ultrasound evidence of tenosynovitis may be worthwhile considering prior to tapering therapy.

Key clinical point: Preoperative elevated plasma D-dimer levels serve as an independent risk factor for poorer long-term survival outcomes in patients who have undergone curative surgery for gastric cancer.

Major finding: Multivariate analysis revealed elevated D-dimer levels to be independently associated with shorter overall survival (adjusted hazard ratio [aHR] 1.633; P = .003) and disease-free survival (aHR 1.58; P = .005).

Study details: Findings are from a retrospective study that included 903 patients with gastric cancer who underwent radical gastrectomy.

Disclosures: This study was sponsored by the National Natural Science Foundation of China, among others. The authors declared no conflicts of interest.

Major finding: Multivariate analysis revealed elevated D-dimer levels to be independently associated with shorter overall survival (adjusted hazard ratio [aHR] 1.633; P = .003) and disease-free survival (aHR 1.58; P = .005).

Study details: Findings are from a retrospective study that included 903 patients with gastric cancer who underwent radical gastrectomy.

Key clinical point: Helicobacter pylori (HP) infection is associated with the tumor expression of programmed death ligand-1 (PD-L1) in patients with gastric cancer.

Major finding: HP infection was significantly associated with the tumor expression of PD-L1 in patients with gastric cancer (odds ratio 1.90; P < .001), with the association not being significantly affected by the sample size, evaluation methods for PD-L1 expression, or quality score (all P > .05).

Study details: This meta-analysis of 10 observational studies investigated the association between HP infection and the tumor expression of PD-L1 in 1870 patients with gastric cancer.

Disclosures: This study was sponsored by the Natural Science Foundation of the Anhui Higher Education Institutions of China and others. The authors declared no conflicts of interest.

Key clinical point: In patients with early gastric cancer (EGC), pylorus-preserving gastrectomy (PPG) vs conventional distal gastrectomy (CDG) results in the harvest of fewer lymph nodes at stations 5, 6, 9, and 11p but similar survival outcomes.

Major finding: Patients who underwent PPG vs CDG had significantly lower numbers of lymph nodes harvested at stations 5, 6, 9, and 11p (weighted mean difference, −3.09; P < .001) but similar overall survival (hazard ratio [HR] 0.63; P = .852) and recurrence-free survival (HR 0.29; P = .900).

Study details: This was a meta-analysis of 16 studies including 4500 patients with EGC who had undergone PPG or CDG with lymph node dissection.
