肺癌是目前我国城乡地区常见的恶性肿瘤之一,发病率和病死率均较高,极易出现局部复发和远处转移,严重影响了患者的生存质量〔1~3〕。肺癌临床类型主要包括鳞形细胞癌、腺癌、肺泡细胞癌、未分化癌。近年来,鳞癌所占比例有所下降,腺癌发病率有明显升高〔4,5〕。临床上肺癌常以放疗作为主要治疗方法〔6〕。本研究旨在探讨适形放疗联合培美曲塞治疗老年晚期非鳞型肺癌的临床疗效和安全性。1材料与方法1.1临床资料选取2010年1月至2012年12月来本院进行
Lung cancer is one of the most common malignant tumors in urban and rural areas in our country. The incidence and mortality are both high, and local recurrence and distant metastasis are easily observed. The quality of life of patients is seriously affected [1-3]. Clinical types of lung cancer include squamous cell carcinoma, adenocarcinoma, alveolar cell carcinoma, undifferentiated carcinoma. In recent years, the proportion of squamous cell carcinoma has declined, the incidence of adenocarcinoma was significantly increased 〔4,5〕. Clinically, lung cancer often radiotherapy as the main treatment [6]. This study aimed to investigate the clinical efficacy and safety of conformal radiotherapy combined with pemetrexed in the treatment of advanced non-squamous lung cancer. 1 Materials and Methods 1.1 clinical data selected from January 2010 to December 2012 to our hospital
