The cross-sectional study of Chinese non-small cell lung cancer surgical treatment patterns in 2013-2014

Abstract

Objective To investigate the current situation of Chinese non-small cell lung cancer(NSCLC) surgical treatment in different centers. And to compare the differences of patient characteristics and treatment patterns. Methods Data of 5 060 NSCLC patients out of 8387 patients from 14 provinces, 17 third-grade class-A hospitals was obtained. All included patients were stage Ⅰ to Ⅲ, and were treated with curative-intent surgeries during the years of 2013 and 2014. Patient characteristics, preoperative examinations, surgical treatment patterns and pathology et al. were analyzed. Results There were 3 204 males and 1 856 females.The patients’ age was among 19~86(59.7±9.11)years old. Mean preoperative FEV1 was(2.23±0.67)L, and mean FEV1/FVC was 81.8%.64.6% patients accompanied with at least one comorbidity. The mean diameter of tumor was(3.28±1.94)cm. Duration of surgery was(181.1±71.0) minutes. Pathology confirmed 59.8% as adenocarcinoma, and 30.2% as squamous carcinoma. The ratio of adenocarcinoma/squamous cell carcinoma was 1.03∶1 in all male patients. And the ratio is 16.4∶1 in female patients. Among all the patients that underwent lobectomies, 50.1% patients underwent micro-invasive surgeries(VATS or mini-incision surgery). The rate of micro-invasive surgery is among 8.3% to 90.2%. The number of lymph nodes stations harvested in lobectomy was 5.9(mean 3.0-7.4). Mean hospital cost was 53 830.8(mean 42 205-100 113 )yuan. Conclusion The Chinese NSCLC patients who underwent surgeries own unique patient characteristics. The baseline characteristics, surgical treatment patterns and hospital cost varied among different centers.
