Clinical Features and Death Risk Factors in COVID-19 Patients with Cancer: A Retrospective Study
Abstract Purpose: Coronavirus disease 2019 (COVID-19) has spread around the world. This retrospective study aims to analyze the clinical features of COVID-19 patients with cancer and identify death outcome related risk factors.Methods: From February 10th to April 15th, 2020, 103 COVID-19 patients with cancer were enrolled. Difference analyses were performed between severe and non-severe patients. A propensity score matching analysis, including 103 COVID-19 patients with cancer and 206 matched non-cancer COVID-19 patients were performed. Next, we identified death related risk factors and developed a nomogram for predicting the probability.Results: In 103 COVID-19 patients with cancer, the main cancer categories were breast cancer, lung cancer and bladder cancer. Compared to non-severe patients, severe patients had a higher median age, and a higher proportion of smokers, diabetes, heart disease and dyspnea. In addition, most of the laboratory results between two groups were significant different. PSM analysis found that the proportion of dyspnea was much higher in COVID-19 patients with cancer. The severity incidence in two groups were similar, while a much higher mortality was found in COVID-19 patients with cancer compared to that in COVID-19 patients without cancer (11.7% vs. 4.4%, P = 0.028). Furthermore, we found that neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein (CRP) were related to death outcome. And a nomogram based on the factors was developed.Conclusion: In COVID-19 patients with cancer, the clinical features and laboratory results between severe group and non-severe group were significant different. NLR and CRP were the risk factors that could predict death outcome.
