摘要目的回顾性分析经手术切除肺多形性癌(PC)病人的临床、影像及病理学资料,并分析生存的预后预测因子。方法研究对象为33例经手术切除PC的病人(男28例,女5例),利用Cox比例风险回归模型分析生存预后预测因子。结果肿瘤大小为1.1~12.0 cm(平均5.4 cm),26例位于肺外周,5例形成空洞,2例伴钙化,14例肿瘤周围呈磨玻璃样改
Abstract Objective To retrospectively analyze the clinical, imaging and pathological data of patients with resected lung pleomorphic carcinoma (PC) and to analyze the prognostic predictors of survival. Methods The subjects were 33 patients (28 males and 5 females) who undergone PC resection. The predictors of survival were analyzed by Cox proportional hazards regression model. Results The tumor size ranged from 1.1 to 12.0 cm (mean, 5.4 cm). Twenty-six of the tumors were located in the periphery of the lung. Five of them formed voids and two had calcification.
