Abstract S12-04: COVID-19 disease in patients with lung cancer in Spain: GRAVID Lung Cancer Patients Disease (GRAVID study)

Abstract Background: Previous reports indicate that lung cancer patients are at an increased risk of severe COVID-19 disease and higher mortality rate compared to general population. However, prognostic factors are not yet clearly identified. The LunG canceR pAtients coVid19 Disease (GRAVID) study aimed to describe clinical characteristics, outcomes and predictors of poor prognosis in patients with lung cancer and COVID-19. Methods: In this large nationwide prospective study, medical records of lung cancer patients with COVID-19 diagnosis from 65 spanish hospitals were included. Clinical features, treatments and disease outcomes were collected. The primary endpoint was to determine any-cause mortality; secondary endpoints were hospitalization and admission at intensive care units (ICU). Risk factors of poor prognosis were identified by univariable and multivariable logistic regression models. Results: Overal, 447 patients were analysed. Mean age was 67.1 ± 9·8 years, and the majority were men (332, 74·3%) and current/former smokers (383 (85.7%). NSCLC was the most frequent cancer type (377, 84.5%), being adenocarcinoma (228, 51·0%) the predominant histology. 354 patients (79.2%) had unresectable stage III or metastatic disease, and 266 (59.5%) where receiving anticancer treatment, mostly first-line chemotherapy. 350 (78.3%) patients were hospitalized for a mean of 13·4 ± 11·4 days, 9 (2.0%) patients were admitted to ICU, and 146 (32.7%) patients died. Advanced disease and corticosteroid treatment at hospitalization were predictors of mortality. Non-terminal stage hospitalized patients with lymphocytopenia and high LDH showed an increased risk of death. Severity of COVID-19 correlated to mortality, admission at ICU and mechanical ventilation. Conclusion: With underlying comorbidities and immunocompromised status, patients with lung cancer and COVID-19 present high hospitalization and mortality rates. These outcomes, alongside the identification of prognostic factors, may inform physicians on risks and benefits for this population to provide individualized oncological care.
