In 2020 in Poland, as a result of the COVID-19 pandemic, 41.5 thousand deaths were registered including 18% (7.3 thousand) among cancer patients (C00-C96). More than a third of deaths due to COVID-19 occurred among tobacco-related cancer patients1. The study aimed to analyze the number of deaths due to COVID-19 among tobacco-dependent cancer patients.

Material and Methods:
Information regarding cancer comes from the National Cancer Registry1. Information on the cause of death in 2020 came from the National Death Database2. Tobacco-related cancers were selected from a list published by the International Agency for Research on Cancer (IARC)3.

In 2020, 7,276 cancer patients died of COVID-19. Among them, 42% concerned patients with tobacco-related cancers, and more than twice as many deaths were registered among men (2029 men and 1032 women). Approximately 27% of deaths related to COVID-19 infection in tobacco-related cancers patients group occurred among patients with colorectal cancer (28% in men and 27% in women), 27% in patients with urinary tract cancer (31% in men and 18% in women), 19% in patients with lung cancer (20% in men and 18% in women), and 5% of patients with cancer of the oral cavity and throat

Patients with tobacco-related cancers had a higher risk of dying from COVID-19 than patients with other types of cancer.
