盆腔体外联合腔内放射治疗宫颈癌72例临床疗效分析

[目的]研究盆腔体外联合腔内放射治疗宫颈癌的临床疗效、不良反应及预后影响因素。[方法]72例初治Ⅰ～Ⅳ期宫颈癌患者接受6-MVX线全盆前后对穿照射4000～5000 cGy,体外放疗3～4次/周,每次180～200 cGy;宫腔内放疗3000～4000 cGy,阴道腔内放疗3000～4500 cGy,1～2次/周,300～700 cGy/次,宫腔与阴道的腔内治疗交替进行。[结果]盆腔体外联合腔内放射治疗宫颈癌的近期有效率是98.6%,5年总生存率为54.1%,其中Ⅱ期5年生存率为75.0%,Ⅲ期5年生存率为41.4%,影响宫颈癌近期疗效的主要因素是肿瘤的大小、肿瘤的病理类型、大小、分期及近期疗效是影响宫颈癌预后的因素。常见的不良反应为腹痛、腹泻、尿频、尿急、排尿痛及骨髓抑制。[结论]盆腔体外联合腔内放射治疗宫颈癌能提高肿瘤的局部控制率,但不能有效地控制全身转移。作者认为放化同步治疗是未来治疗子宫颈癌的最佳方法。
