Epidemiology and clinical course of SARS-CoV-2 infection in cancer patients in the veneto oncology network: The ROVID study

ABSTRACT

Background: COVID-19 pandemic started in Italy with clusters identified in Northern Italy. Since the beginning, the Veneto region started a proactive approach, including testing for SARS-CoV-2 part of the asymptomatic population and healthcare providers. The Veneto Oncology Network ROV licensed a dedicated PDTA to ensure proper care minimizing the risk of infection in cancer patient (pts). At the same time, a regional registry (ROVID) has been set up, to describe epidemiology and clinical course of SARS-CoV-2 infection in cancer pts. Materials and methods: All pts with cancer diagnosis and documented SARS-CoV-2 infection are eligible. The following information are recorded age, cancer diagnosis, stage, tumor biology, comorbidities, presence of COVID- 19 symptoms, anticancer treatment at the time infection (type, aim, line of therapy, discontinuation, recovery), other medical treatments, hospitalization, treatments for SARS-CoV-2 infection, fate of the infection. Results: 144 pts from 18 centers have been enrolled. Mean age at the time infection 69 yrs (25 to 95 yrs). The 5 most common cancer types were breast cancer (n=26), colorectal, prostate, lung cancer (n=16 each), melanoma (n=10). Distribution by stage was as follows I 19%, II 9%, III 13%, IV 59%. Lung metastases were documented in 15% of the cases. 77% of the pts had at least one comorbidity. COVID-19 symptoms were reported in 78% of the pts. Active anticancer therapy at the time of the infection was reported for 71 pts (chemotherapy n=37, targeted therapy n=14, hormonal therapy n=13, immunotherapy n=6). Treatment was discontinued because of infection in 44 case. 101 pts were hospitalized;45 received low flow oxygen support and 26 received non-invasive mechanical ventilation, high flow nasal cannula or endotracheal intubation. The fate of infection is available for 95 cases so far 44 infection resolution with confirmed negative swab, 16 with clinical resolution discharged with positive swab, and 35 deaths. Among cases with fatal exitus, 22 were attributable to COVID-19. Conclusions: Data collection is still ongoing, including further follow up and results of serological tests, where available. The mortality rate reported in this study is in line with other registry of cancer patients, confirming the frailty of this population. These data reinforce the need to protect cancer patients from SARS-CoV2 infection.
