RESUMO
Introduction: Active cancer increases the odds of death among patients with COVID-19.1 Cancer patients may be at increased risk of complications and mortality from COVID-19 owing to the systemic effects of malignancy, immune suppression after chemotherapy, treatment-related complications and presence of co-morbidities.2 They may develop serious complications necessitating ICU admission. In a meta-analysis, the pooled mortality in cancer patients with COVID-19 admitted to an ICU was 60.2%.3 Our hospital is a tertiary referral cancer centre, and the ICU admitted cancer patients with Covid-19 throughout the pandemic. Objective(s): To determine the 30-day in-hospital mortality of adult cancer patients with Covid-19 admitted to the ICU. We also aimed to determine the factors associated with mortality in cancer patients with Covid-19. Method(s): After approval from the Institutional Ethics Committee, data of all cancer patients (age = 16 years) with Covid-19 admitted to the ICU between March 2020 and March 2021 were retrieved from the hospital records. In case of multiple ICU admissions, data from the first admission was recorded. Data recorded included demographic details, type of cancer (solid, haematological), surgical status, APACHE-II and SOFA scores, C-reactive protein, and interventions in ICU. The primary outcome was 30-day in-hospital mortality. Data were analysed using Man-Whitney test and chi-square test. A multivariable regression analysis was carried out to determine factors associated with mortality. Result(s): Data of 127 cancer patients with Covid-19 was analysed. The median [interquartile range, IQR] age was 55 (43-62) years, and there were 50 females (39.3%). Comorbidities were present in 46 (36%) patients, the commonest being diabetes (29 patients) and hypertension (31 patients). The median [IQR] APACHE-II and SOFA scores were 15[8-20] and 4[2-7], respectively. Overall, 62/127 patients died, and 30-day hospital mortality was 49%. There were 30 patients with haematological malignancy and 97 with solid tumours with 30-day in-hospital mortality rates of 46.7% and 49.5%, respectively;p = 0.84). Amongst patients with solid tumours, there was no difference in mortality in surgical patients compared to non-surgical patients (43.3% vs. 52.2%;p = 0.42). Table 1 summarises the parameters and interventions in survivors and non-survivors. On multivariable analysis, only the change in SOFA score from Day 1 to Day 3 was independently associated with outcome (Odds ratio 1.36 (95% confidence interval 1.01-1.84, p-0.04). Conclusion(s): In patients with cancer and Covid-19 and age =16 years admitted to our ICU, the crude 30-day hospital mortality was 47%. There was no association of mortality with cancer type or surgical status. The only independent predictor of mortality was progression of organ failure. Cancer patients with Covid-19 have a reasonable outcome and should be given a trial of intensive care.
