体质量指数与行胃癌切除术后患者复发率的关系

Relationship between low body mass index and morbidity after gastrectomy for gastric cancer

目的本研究试图探索低体质量指数(BMI)与胃癌术后患者复发率的关系。方法研究对象为2009年至2015年在西安交通大学第一附属医院行胃癌切除术的1 805名患者。根据BMI指数将患者分为两组,即低体质量组(BMI<18.5)和非低体质量组(BMI≥18.5)结果总体并发症发生率为24.4%。肺部并发症在低体质量组的发生率显著高于正常体质量组(分别为10.5%与3.8%)。结论低体质量患者患肺部并发症可能性更高。此外,低体质量和晚期胃癌是胃癌术后发生肺部并发症的独立危险因素。

Objective This study aimed to evaluate the association between low body mass index（BMI）and morbidity after gastric cancer surgery.Methods A total of 1 805 patients were included in the study.Clinicopathologic and morbidity data were analyzed by dividing the patients into 2 groups：underweight patients（BMI18.5 kg/m2）and non-underweight patients（BMI≥18.5 kg/m2）.Results The overall complication rate as determined by our study was 24.4%.Pulmonary complications occurred more frequently in the underweight group（UWG）than in the non-UWG（10.5% vs.3.8%,respectively;P=0.012）.Conclusion We concluded that underweight patients had a higher pulmonary complication rate.Additionally,underweight and advanced cancer stage were determined to be independent risk factors for the development of postoperative pulmonary complications.
