THE IMPACT OF THE COVID-19 PANDEMIC ON THE RESULTS OF SURGICAL TREATMENT OF PATIENTS WITH LUNG MALIGNANCIES

Objective. To study the effect of COVID-19 pandemic on the results of surgical treatment of patients with malignant lung tumors.

Materials and methods. The material for the study included observations of 1187 patients with malignant lung tumors who underwent radical surgical treatment in the volume of anatomic lung resection (lobectomy, bilobectomy, pneumonectomy, including video-assisted and combined ones) at the oncologic thoracic department of the Alexandrov Russian Research Center for Oncology and Medical Radiology. The patients were divided into 2 groups: those operated on in 2018—2019 before pandemic onset and in 2020—2021, i.e. in the pandemic period. The 30- and 90-day mortality rates and 1-year overall survival were chosen as the main outcome measures.

Results. The 30- and 90-day mortality rates for 2018—2019 and 2020—2021 were 2,8 % and 3,8 % (p=0,3061) and 4,4 % and 6,4 % (p=0,1197), respectively. There were no significant intergroup differences in overall survival rates (p=0,3725).

Conclusions. The COVID-19 pandemic did not result in a statistically significant worsening of surgical outcomes in patients with malignant lung tumors compared with the pre-pandemic period.
