Long-Term Survival of Cancer Patients Following COVID-19 Infection: Prognostic Value of Inflammatory Indices and Vaccination Status

Le résumé fourni par la source

The survival outcomes of cancer patients exposed to Coronavirus Disease 2019 (COVID-19), the duration required to resume oncological treatment, and the subsequent course of their malignancy remain areas with limited data. This retrospective study evaluated 128 cancer patients hospitalized for COVID-19 treatment between April 2020 and October 2023. Of the cohort, 39.8% were women and 60.2% were men. Findings revealed that patients with metastatic lung involvement faced a 3.34-fold increased risk of death during the acute infection. In the post-COVID survival cohort, multivariate analysis indicated that younger age, higher hemoglobin levels, higher systemic inflammatory index, lower pan-immune inflammation value, and absence of active cancer were associated with longer survival. Additionally, vaccine-related survival differences were observed; however, these findings should be interpreted cautiously as they likely reflect confounding factors such as prioritizing high-risk patients for certain vaccine types rather than a direct causal relationship. Notably, while treatment delays were common among patients with disease progression, these delays did not result in a statistically significant difference in overall survival during the long-term follow-up.
