Changes in the Number of Newly Diagnosed Lung Cancer Patients Before and During the COVID-19 Pandemic: A single-Center Experience

Abstract This study was conducted to determine whether there was an effect on the hospital admissions of newly diagnosed lung cancer (NDLC) patients in Turkey during the COVID-19 pandemic. In this retrospective study, NDLC patients were recorded from the Hospital Information Management System between January,1 2015-December, 31, 2020, at our tertiary hospital. The number of NDLC patients diagnosed in 2020 was compared with each year of 2017-2019. Between 2017 and 2020, 15,150 NDLC cases were analyzed. The number of NDLC patients by year were; 4,030 patients in 2017, 4,004 patients in 2018, 4,391 patients in 2019, and 2,725 in 2020, respectively. In 2020, NDLC patients decreased by 38%, 32%, 32% compared to 2019, 2018, and 2017, respectively. The late admission of lung cancer patients might result in the advanced stage, missing the chance for surgery, and decreased survival. Precautions should be considered to diagnose and treat lung cancer patients in specialized centers during a pandemic due to epidemic diseases such as COVID-19.
