Dataset of a study investigating the influence of COVID-19 pandemic on lung cancer surgery in Poland.
The COVID-19 pandemic has led to a reduction in the availability of healthcare services for patients. The aim of the present study was to analyze the impact of the COVID-19 pandemic on the surgical treatment of lung cancer in Poland. Data were obtained from the Polish National Lung Cancer Registry. We compared the period from before the pandemic (year 2019) to the period of the pandemic (year 2020) in terms of the number of operations carried out, percentage of patients who underwent invasive mediastinal staging, surgical approach, type of surgery, percentage of bronchial sleeve resections, histology, pathological stage, total length of hospital stay, duration of postoperative stay, and outcome at discharge. We found that during COVID-19 pandemic the number of anatomical lung resections in lung cancer decreased by over 20%, which was related to the daily number of new COVID-19 cases in Poland. We also found that in 2020, compared to 2019, the percentage of patients with advanced pathological stage was higher, duration of total hospital stay and postoperative hospital stay were shorter, and the rate of use of minimally invasive approach for pulmonary resection was higher. There were no changes in preoperative invasive mediastinal staging, types of resection and postoperative mortality. We concluded, that COVID-19 pandemic had a significant negative impact on radical surgical treatment of patients with resectable lung cancer.

Categorical data were analyzed using the chi-square or Fisher–Freeman–Halton test or as the difference between two proportions. The normality of distribution was tested using the Shapiro–Wilk test. Comparisons between two groups were performed using Student’s t test, Mann–Whitney U test, or Wilcoxon test. The relationship between variables was analyzed using Spearman’s rank-order correlation coefficient. All results were considered significant at a p value of <0.05. Statistical analyses were performed using Statistica 13.0 (StatSoft, Tulsa, OK, USA).
