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.

COVID-19疫情导致波兰患者医疗服务的可用性降低。本研究旨在分析COVID-19疫情对波兰肺癌手术治疗的影响。数据来源于波兰国家肺癌登记处。我们对比了疫情前（2019年）和疫情期间（2020年）的手术数量、进行侵入性纵隔分期患者的百分比、手术方式、手术类型、支气管袖状切除术的百分比、组织学、病理分期、住院总时长、术后住院时长以及出院时的预后。研究发现，在COVID-19疫情期间，肺癌解剖性肺切除术的数量较疫情前下降了20%以上，这与波兰每日新增COVID-19病例数相关。此外，2020年与2019年相比，晚期病理分期患者的百分比更高，住院总时长和术后住院时长均缩短，肺叶切除手术中应用微创技术的比例也更高。术前侵入性纵隔分期、切除类型及术后死亡率未发生变化。我们得出结论，COVID-19疫情对可切除肺癌患者的根治性手术治疗产生了显著的负面影响。
