Abstract
Background: There is limited data on outcomes in cancer patients with coronavirus disease 2019 (COVID-19) from lower middle-income countries (LMICs).

Patients and methods: This was an observational study, conducted between 12 April and 10 June 2020 at Tata Memorial centre, Mumbai, in cancer patients undergoing systemic therapy with laboratory confirmed COVID-19. The objectives were to evaluate cumulative 30-day all-cause mortality, COVID-19 attributable mortality, factors predicting mortality, and time to viral negativity after initial diagnosis.

Results: Of the 24 660 footfalls and 7043 patients evaluated, 230 patients on active systemic therapy with a median age of 42 (1-75) years were included. COVID-19 infection severity, as per WHO criteria, was mild, moderate, and severe in 195 (85%), 11 (5%), and 24 (11%) patients, respectively. Twenty-three patients (10%) expired during follow-up, with COVID-19 attributable mortality seen in 15 patients (6.5%). There were no mortalities in the pediatric cohort of 31 (14%) patients. Advanced stage cancer being treated with palliative intent vs others [30-day mortality 24%% vs 5%, odds ratio (OR) 5.6, 95% CI 2.28-13.78, P < .001], uncontrolled cancer status vs controlled cancer (30-day mortality37.5%% vs 4%%, OR 14, 95% CI 4.46-44.16, P < .001) and severe COVID-19 vs mild COVID-19 (30-day mortality 71% vs 3%, OR 92.29, 95% CI 26.43-322.21, P < .001) were significantly associated with mortality. The median time to SARS-CoV-2 RT-PCR negativity was 17 days [interquartile range (IQR)17-28) in the cohort.

Conclusions: The mortality rates in cancer patients with COVID-19 who are receiving systemic anti-cancer therapy in LMICSs are marginally higher than that reported in unselected COVID-19 cohorts with prolonged time to viral negativity in a substantial number of patients. The pediatric cancer patients tended to have favorable outcomes.
