Chimeric antigen receptor modified T cells targeting CD19 and CD20 have shown activity in Phase I, II trials of patients with hematological malignancies. We conducted a systematic review and meta-analysis of all published clinical trials studying the role of efficacy as well as safety of CD-19 and CD-20 chimeric antigen receptor-T therapy for B-cell hematologic malignancies. A total of 16 studies with 195 patients were identified. The pooled analysis showed an overall response rate of 61% (118/195) with complete response of 42% (81/195) and partial response of 19% (37/195). Major adverse events were cytokine release syndrome 33%, neurotoxicity 33% and B-cell aplasia 54%. Collectively, the results indicate encouraging response in relapsed/refractory B lymphoma and leukemia, especially in acute lymphoblastic leukemia (ALL) patients.
PURPOSE: Gender disparity persists in academic medicine. Female faculty are underrepresented in leadership positions and have lower research output. We studied gender differences in faculty rank and departmental leadership and contributing factors among academic hematologists and oncologists in the United States. METHODS: For clinical faculty at 146 hematology or oncology fellowship programs listed in the Fellowship and Residency Electronic Interactive Database, we collected data on demographics, academic rank, and research output using the Doximity and Scopus databases. We compared unadjusted characteristics of men and women by using 2-sided t tests and χ2 tests where appropriate. To predict probability of full professorship or leadership position among men versus women, we performed multivariable logistic regression analysis adjusted for clinical experience in years, number of publications, h-index, clinical trial investigator status, National Institutes of Health funding, and workplace ranking (top 20 v not). RESULTS: Two thousand one hundred sixty academic hematologists and oncologists were included. Women composed 21.9% (n = 142) of full professors, 35.7% (n = 169) of associate professors, and 45.4% (n = 415) of assistant professors. Thirty percent (n = 70) of departmental leaders were women. Female faculty, compared with male faculty, had a lower mean h-index (12.1 v 20.9, respectively; P < .001) and fewer years of professional experience since fellowship (10 v 16 years, respectively; P < .001). After adjusting for duration of clinical experience, academic productivity, and workplace ranking, the odds of obtaining professorship (odds ratio [OR], 1.05; 95% CI, 0.71 to 1.57; P = .85) or divisional leadership (OR, 0.57; 95% CI, 0.20 to 1.58; P = .28) for female physicians were not different compared with male physicians. CONCLUSION: Gender disparity exists in senior ranks of academic hematology and oncology; however, gender is not a significant predictor in achieving professorship or department leadership position.
Direct oral anticoagulants (DOACs) are widely used for the prevention of stroke in nonvalvular atrial fibrillation, treatment of deep venous thrombosis and pulmonary embolism, and as prophylaxis after hip and knee surgery after approval by the Food and Drug Administration. In the last decade, DOACs were studied for various indications; this review is focused on rivaroxaban, a factor Xa inhibitor, which is used in an expanded evidence-based fashion for coronary artery disease, peripheral artery disease, heart failure, malignancy, and prophylaxis of deep venous thrombosis in acute medical illnesses.
e12057 Background: Several RCTs have evaluated a shorter duration of T ( < 12 months) with hopes of similar efficacy, reduced cardiotoxicity, cost and burden of treatment. Of the 5 major studies, PERSPHONE showed that 6 months was non-inferior compared to 12 months. However, four additional studies of shorter duration failed to demonstrate non-inferiority. Therefore, we performed an updated systematic review and a meta-analysis to assess the optimal duration of adjuvant T. Methods: MEDLINE, EMBASE, Cochrane, Scopus and conference proceedings were searched to identify RCTs comparing one year of adjuvant T with a shorter duration in early-stage HER2+ breast cancer. The DerSimonian-Laird random-effects Meta-Analysis was performed using CMAv3 software to derive pooled Hazard Ratio (HR) estimates for overall survival (OS, Disease-Free Survival (DFS) and Odds Ratio(OR) estimates of cardiac toxicity. Q-test was used to assess between-study heterogeneity; I2 statistic was computed to express the percentage of the total observed variability due to study heterogeneity. The risk for bias was assessed using the Cochrane Collaboration’s tool. Results: We screened 1772 citations and identified 5 studies(n = 11,377) for analysis. 5691 patients were randomized to 12 months of adjuvant T while 5686 were randomized to a shorter duration (3 studies evaluated 6 vs 12 months, 2 studies evaluated 9 weeks vs 12 months). OS (HR, 1.16, 95% CI 1.03-1.31, P= 0.015,I2 0.00, p= 0.837) and DFS (HR, 1.14, 95% CI 1.02-1.26 , P = 0.016,I2 14.90, p= 0.319) were significantly worse in patients receiving shorter duration T as compared to 12 months. Cardiotoxicity was significantly higher in the 12 month group vs shorter duration (OR, 2.10, 95% CI 1.58-2.80, p = 0.000 ,I2 51.182, p= 0.085). Grade 3/4 cardiac events and cardiac events leading to discontinuation of therapy were significantly higher in patients receiving 12 months (HR 2.06, 95% CI 1.60-2.63, P = 0.000, I2 3.967, p= 0.384). There was no significant heterogeneity among studies. Risk of bias was low. Conclusions: Twelve months of adjuvant T is associated with significantly better DFS and OS compared to a shorter duration. As such, 12 months should remain the standard of care for most patients. There is an unmet need to identify lower risk groups which might do well with from shorter duration of HER2-directed therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
