Abstract
in English, Chinese

Objective: To explore the surgical safety of patients with comorbid non-small cell lung cancer (NSCLC) and pneumoconiosis.

Methods: In this study, the clinical data of 165 NSCLC patients treated at West China Fourth Hospital, Sichuan University from August 2019 to May 2021 were collected. Among them, 21 patients with comorbid pneumoconiosis were included in the pneumoconiosis group, and the remaining 144 patients were included in the general group. Radical resection for lung cancer was performed in both groups. The perioperative clinical data, including preoperative, intraoperative and postoperative indicators, of the two groups were compared and analyzed.

Results: There was no perioperative death in either group. The proportions of male patients and patients with smoking history in the pneumoconiosis group were significantly higher than those in the general group ( P<0.05). The body mass index (BMI), pulmonary ventilation function and diffusion function in the pneumoconiosis group were significantly lower than those in the general group ( P<0.05). There was no significant difference in the median operative time and the median volume of intraoperative blood loss between the pneumoconiosis group and the general group. In the pneumoconiosis group, the proportion of advanced tumors (stage Ⅱ/Ⅲ), incidence of postoperative complications, median duration of postoperative intubation, and postoperative length of hospital stay were higher/longer than those of the normal group ( P<0.05). Compared with the general group, the incidences of lymph node calcification, dense pleural adhesion and surgical method alteration (switching from thoracoscopic surgery to open surgery or video-assisted thoracoscopy) were also significantly higher in the pneumoconiosis group ( P<0.05). Univariate analysis showed that age, smoking history, pneumoconiosis, pulmonary ventilation dysfunction, lymph node calcification, dense pleural adhesion and the volume of intraoperative blood loss were the risk factors for postoperative complications. Further multivariate regression analysis demonstrated that smoking history ( OR=1.37, P<0.05), lymph node calcification ( OR=2.36, P<0.05) and pulmonary ventilation dysfunction ( OR=5.21, P<0.05) were independent risk factors for postoperative complications.

Conclusion: NSCLC patients with comorbid pneumoconiosis face relatively greater risks during the perioperative period when they undergo radical resection for lung cancer. Therefore, the close attention of surgeons and the nursing staff should be raised accordingly.

目的: 探讨合并尘肺的非小细胞肺癌患者的手术安全性。

方法: 本研究收集了从2019年8月–2021年5月在四川大学华西第四医院就诊的165例非小细胞肺癌患者的临床资料，其中21例患者合并尘肺，为尘肺组，剩余144例患者为普通组。两组均行肺癌根治术。比较分析两组患者围手术期的临床资料，包括术前、术中、术后指标。

结果: 两组患者均无围手术期死亡。尘肺组男性患者比例以及有吸烟史患者比例高于普通组（P<0.05）；尘肺组患者体质量指数、肺通气功能、弥散功能低于普通组（P<0.05）。尘肺组中位手术时间和中位术中出血量与普通组比较差异无统计学意义；尘肺组Ⅱ期/Ⅲ期肿瘤比例、术后并发症发生率、中位术后拔管天数和中位术后住院天数均高/长于普通组（P<0.05）；尘肺组淋巴结钙化、胸膜致密粘连发生率和更改手术方式发生率（从胸腔镜手术转换为开放手术或胸腔镜辅助）也较普通组更高（P<0.05）。单因素分析显示年龄、吸烟史、尘肺、肺功能受损、淋巴结钙化、胸膜致密粘连、术中出血量是非小细胞肺癌患者发生术后并发症的危险因素（P<0.05），进一步多因素回归分析显示吸烟史（OR=1.37，P<0.05）、淋巴结钙化（OR=2.36，P<0.05）和肺功能受损（OR=5.21，P<0.05）是发生术后并发症的独立危险因素。

结论: 尘肺患者行肺癌根治手术围手术期风险相对更高，应引起术者及护理人员重视。
