Outcomes of COVID‐19 in patients with lymphomas participating in registered clinical trials: A real‐world study from China in the Omicron outbreak era

Abstract

AbstractBackgroundThis real‐world study investigated the outcome of COVID‐19 in lymphoma patients participating in registered clinical trials and explored potential risk factors with the outcome of COVID‐19 during the first wave of the Omicron outbreak in China.MethodsOne hundred and ten patients participating in registered clinical trials and diagnosed with COVID‐19 in our center between December 1, 2022, and January 31, 2023, were included.ResultsFour (3.6%) patients were identified as severe COVID‐19 and 2 (1.8%) as critical COVID‐19, respectively. The mortality rate observed was 2.73% for the entire cohort, 33.3% for the severe/critical COVID‐19 group, and 18.8% for the hospitalized group. The 90‐day OS was 98.2% for the entire cohort, 66.7% for the severe/critical COVID‐19 group, and 87.5% for the hospitalized group. Advanced age (≥70 years), comorbidities, and PI3K inhibitor‐containing regimen were significantly associated with the severity of COVID‐19. Patients with indolent B‐cell non‐Hodgkin lymphomas were less likely to be hospitalized for COVID‐19.ConclusionThis study reported similar clinical features of COVID‐19 in our cohort with that of non‐hematological malignancy (HM) patients, while the proportion of severe/critical COVID‐19 and the mortality rate were relatively higher than non‐HM patients. Our findings provided valuable experience to aid clinical researchers with managing lymphoma patients participating in registered clinical trials during the ongoing pandemic of the Omicron variant.
