Low incidence of cardiotoxicity in patients with non-Hodgkin lymphoma receiving EPOCH after prior anthracycline exposure.

OBJECTIVE: To describe the incidence of cardiotoxicity in patients with anthracycline exposure who subsequently receive EPOCH for non-Hodgkin lymphoma (NHL). METHODS: We conducted a retrospective cohort study of adults with anthracycline exposure who subsequently received EPOCH for NHL at Memorial Sloan Kettering Cancer Center. The primary outcome was cumulative incidence of arrhythmia, heart failure (HF), left ventricular (LV) dysfunction, or cardiac death. RESULTS: Among 140 patients, most had diffuse large B-cell lymphoma. Inclusive of EPOCH, median cumulative doxorubicin-equivalent dose was 364 mg/m2 ; exposure was 400 mg/m2 or higher in 41%. With median 36-month follow-up, 23 cardiac events were noted in 20 patients. Cumulative incidence of cardiac events at 60 months was 15% (95% confidence interval [CI]: 9%-21%). When limited to LV dysfunction/HF, cumulative incidence at 60 months was 7% (95% CI: 3%-13%), with most events occurring after the first year. Univariate analysis indicated only history of cardiac disease and dyslipidemia to be associated with cardiotoxicity; no other risk factors, including cumulative anthracycline dose, were identified. CONCLUSIONS: In this retrospective cohort, representing the largest experience in this setting with extended follow-up, cumulative incidence of cardiac events was low. Rates of LV dysfunction or HF were particularly low, suggesting infusional administration may mitigate risk despite prior exposure.

Successful implementation of outpatient R ± DHAX (rituximab, dexamethasone, oxaliplatin, cytarabine) for select patients with lymphoma: a single-center experience.

R ± DHAX has been traditionally administered to inpatient due to the timing of chemotherapy administration and the perceived need for close monitoring of adverse effects. To administer R ± DHAX outpatient, a multidisciplinary task force created clinical and educational guidelines which were implemented through two phases: pilot and expansion. The pilot program determined the feasibility of transitioning R ± DHAX outpatient at a single infusion site. The expansion phase led to a service-wide implementation across all outpatient sites. A total of 40 patients were included, of which 23 patients completed all cycles, outpatient, 12 transitioned inpatient to outpatient administration, and 5 transitioned outpatient to inpatient administration. The success rate of outpatient R ± DHAX administration was 90% (36 patients successfully completed outpatient administration/40 total patients). No cytarabine-related cerebellar or ophthalmic toxicity was reported. Outpatient R ± DHAX saved 192 hospital days. R ± DHAX could be successfully administered outpatient with minimal safety concerns and reduced hospital bed utilization.

IVAC With or Without Rituximab for Relapsed or Refractory B-Cell Non-Hodgkin Lymphomas: Real-World Experience in the Modern Era.

INTRODUCTION: Part B of the modified Magrath regimen (IVAC) +/- rituximab (R) is recommended as standalone therapy by national guidelines for management of relapsed/refractory Burkitt lymphoma, and is used in other non-Hodgkin lymphomas (NHL). Activity of IVAC in B-cell NHL, particularly with R, and its toxicity remain incompletely described. PATIENTS AND METHODS: We reviewed patients with relapsed/refractory B-cell NHL treated with IVAC +/- R between 2004 and 2019 at Memorial Sloan Kettering Cancer Center to assess efficacy and toxicity. RESULTS: Among 54 eligible patients (median 2 prior lines of therapy), 76% had diffuse large B-cell lymphoma; 30% had central nervous system involvement at IVAC initiation. Objective response rate was 48%. At median 22-month follow-up, median progression-free and overall survival were 3.1 months and 4.9 months, respectively. Grade ≥ 3 anemia (93%), neutropenia (94%), and thrombocytopenia (100%; all grade 4) were common. Febrile neutropenia occurred in 65% and did not appear to be influenced by use of antimicrobial or granulocyte colony stimulating factor prophylaxis. Mortality was attributed to treatment in 19% of evaluable patients. CONCLUSION: The clinical efficacy and utility of IVAC +/- R remain unclear. However, its profound hematologic toxicity and life-threatening complications despite prophylactic measures warrant careful consideration of alternatives.

Outpatient clinical pharmacy practice in the face of COVID-19 at a cancer center in New York City.

PURPOSE: With the rapid spread of COVID-19 in New York City since early March 2020, innovative measures were needed for clinical pharmacy specialists to provide direct clinical care safely to cancer patients. Allocating the workforce was necessary to meet the surging needs of the inpatient services due to the COVID-19 outbreak, which had the potential to compromise outpatient services. We present here our approach of restructuring clinical pharmacy services and providing direct patient care in outpatient clinics during the pandemic. DATA SOURCES: We conducted a retrospective review of electronic clinical documentation involving clinical pharmacy specialist patient encounters in 9 outpatient clinics from March 1, 2020 to May 31, 2020. The analysis of the clinical pharmacy specialist interventions and the impact of the interventions was descriptive. DATA SUMMARY: As hospital services were modified to handle the surge due to COVID-19, select clinical pharmacy specialists were redeployed from the outpatient clinics or research blocks to COVID-19 inpatient teams. During these 3 months, clinical pharmacy specialists were involved in 2535 patient visits from 9 outpatient clinics and contributed a total of 4022 interventions, the majority of which utilized telemedicine. The interventions provided critical clinical pharmacy care during the pandemic and omitted 199 in-person visits for medical care. CONCLUSION: The swift transition to telemedicine allowed the provision of direct clinical pharmacy services to patients with cancer during the COVID-19 pandemic.
