目的:探讨术中联合125I粒子植入治疗中晚期食管鳞癌的安全性、疗效及影响患者生存率的因素.方法:我院收集2001年-2006年间100例术中联合125I粒子植入治疗食管鳞癌患者(根据术前CT分期标准:Ⅱ-Ⅲ期)临床资料,剔除姑息性切除及转流术患者5例,最终入组95例食管鳞癌根治性切除联合125I粒子植入患者,并对其进行分析.患者均依据TPS所制定的剂量,在术中直视下125I粒子组织间植入.选用0.3-0.7mCi的125I粒子10-40粒,总活度在7-28mCi,肿瘤匹配周边剂量40-80Gy.通过单因素及多因素分析影响患者术后生存率的因素.结果:截止2011年6月30日,95例患者均获随访,40例仍存活.患者术后粒子验证质量评估满意,无严重并发症发生,无患者死于手术或粒子植入治疗,局部复发率11.6％,远处转移率41.1％.1、3、5年患者总体生存率分别为90.5％、58.9％、42.1％,中位生存期38个月(95％ CI:25-51个月).单因素生存分析显示年龄组(P =0.0006)、肿瘤分段(P =0.0013)、术前CT分期(P=0.0003)、粒子活度(P＝0.0026)和肿瘤匹配周边剂量(P =0.0021)以及术后病理分期(P=0.0001),均影响术中联合125I粒子植入治疗患者的长期生存率.COX回归多因素分析后显示与预后有关的因素为粒子活度(P=0.017)和肿瘤匹配周边剂量(P=0.000)以及术后病理分期(P =0.0000).结论:术中联合125I粒子植入治疗中晚期食管鳞癌简单、安全、有效,可降低局部复发率、提高患者生存率.其中粒子活度、MPD和术后病理分期是影响患者预后的主要因素.125I粒子单粒活度0.5-0.7mCi,肿瘤匹配周边剂量60-70Gy合理可行.
