Background: This 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.
Methods: One 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.
Results: Four (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.
Conclusion: This 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.
