Forming the Hematology-Oncology Collaborative Videoconferencing (CO-VID) Learning Initiative: Experiential Lessons Learned From a Novel Trainee-Led Multidisciplinary Virtual Learning Platform.

PURPOSE: COVID-19 challenged medical practice and graduate medical education. Building on previous initiatives, we describe and reflect on the formative process and goals of the Hematology-Oncology Collaborative Videoconferencing Learning Initiative, a trainee-led multi-institutional virtual COVID-19 learning model. METHODS: Clinical fellows and faculty from 13 US training institutions developed consensus needs, goals, and objectives, recruited presenters, and generated a multidisciplinary COVID-19 curriculum. Weekly Zoom conferences consisted of two trainee-led instructional segments and a trainee-moderated faculty Q&A panel. Hematology-oncology training program faculty and trainees were the targeted audience. Leadership evaluations consisted of anonymized baseline and concluding mixed methods surveys. Presenter evaluations consisted of session debriefs and two structured focus groups. Conference evaluations consisted of attendance, demographics, and pre- or postmultiple-choice questions on topic learning objectives. RESULTS: In 6 weeks, the initiative produced five conferences: antivirals, anticoagulation, pulmonology, provider resilience, and resource scarcity ethics. The average attendance was 100 (range 57-185). Among attendees providing both pre- and postconference data, group-level knowledge appeared to increase: antiviral (n = 46) pre-/postcorrect 82.6%/97.8% and incorrect 10.9%/2.2%, anticoagulation (n = 60) pre-/postcorrect 75%/93.3% and incorrect 15%/6.7%, and pulmonary (n = 21) pre-/postcorrect 66.7%/95.2% and incorrect 33.3%/4.8%. Although pulmonary management comfort appeared to increase, comfort managing of antivirals and anticoagulation was unchanged. At the conclusion of the pilot, leadership trainees reported improved self-confidence organizing multi-institutional collaborations, median (interquartile range) 58.5 (50-64) compared with baseline 34 (26-39), but did not report improved confidence in other educational or leadership skills. CONCLUSION: During crisis, trainees built a multi-institutional virtual education platform for the purposes of sharing pandemic experiences and knowledge. Accomplishment of initiative goals was mixed. Lessons learned from the process and goals may improve future disaster educational initiatives.

Observation Versus Immediate Reinduction for Acute Myeloid Leukemia Patients With Indeterminate Day 14 Bone Marrow Results.

INTRODUCTION: The benefit of immediate reinduction chemotherapy for patients with indeterminate day 14 bone marrow results (≤ 20% cellularity and 5%-20% blasts) remains unclear. We report our experience with patients with acute myeloid leukemia (AML) with indeterminate day 14 bone marrow biopsy results treated with reinduction chemotherapy versus observation alone. MATERIALS AND METHODS: We performed a retrospective study to assess the outcomes of adult patients with newly diagnosed AML treated with or without reinduction chemotherapy for indeterminate day 14 bone marrow results. RESULTS: We identified 50 patients with indeterminate day 14 bone marrow results. Of the 50 patients, 25 (50%) had received reinduction therapy and 25 (50%) had not. Of the 50 patients, 24 (48%) had poor risk disease, 12 in the reinduction arm (10 with an abnormal karyotype and 2 with a normal karyotype with molecular abnormalities) and 12 in the observation arm (6 with an abnormal karyotype and 6 with a normal karyotype with molecular abnormalities). The overall response rate (complete remission plus complete remission with incomplete count recovery) was similar in both treatment arms (80% vs. 80%). No statistically significant difference was found in the median overall survival (13 months vs. 21 months; P = .88) or relapse-free survival (13 months vs. 33 months; P = .53) between the 2 treatment arms. CONCLUSION: Our study did not find a statistically significant difference in the overall response rates or survival outcome measures for patients with AML and indeterminate day 14 bone marrow in the 2 treatment groups. Our findings question the utility of immediate reinduction chemotherapy and raise concern regarding overtreatment in this patient population. Larger studies investigating similar outcomes are warranted to validate our clinical findings.

Cytomegalovirus reactivation is associated with a lower rate of early relapse in myeloid malignancies independent of in-vivo T cell depletion strategy.

The association between cytomegalovirus (CMV) reactivation and relapse risk has not been evaluated in relation to T cell depletion strategies. We evaluated 93 patients who underwent allogeneic hematopoietic stem cell transplantation (HSCT) and analyzed the association between T cell depletion strategies with the cumulative incidence of relapse and CMV reactivation. A total of 33% of patients who received ATG vs. 34% who received alemtuzumab developed CMV reactivation. The cumulative incidence of relapse was 3% at 1year and 20% at 3 years in patients with CMV reactivation vs. 30% at 1year and 38% at 3 years in patients without CMV reactivation (p=0.02). When analyzed separately, this effect persisted in the myeloid, but not the lymphoid group. There was a numerical trend towards increased non-relapse mortality (NRM) in patients with CMV reactivation, especially in the myeloid group. The choice of T cell depleting agent and the rate of CMV reactivation were not associated with different overall survival (OS) rates. These results suggest that the choice of T cell depletion strategy may have similar effects on rates of CMV reactivation, disease relapse, and survival. Further studies examining these variables in patients not exposed to in-vivo T cell depleting agents may be of interest.
