补充资料:子宫内膜癌腔内放射治疗


子宫内膜癌腔内放射治疗


子宫内膜癌腔内放疗有:①传统方法,使用治疗子宫颈癌的治疗容器,如宫腔管及阴道容器,(容器有:斯德哥尔摩盒式、巴黎弓形、曼彻斯特卵圆形、北京型等)。其缺点是子宫角部受量不足;②Heyman倡导宫腔填充法,将含有镭或其他同位素的金属小囊填满于子宫腔内,使宫腔各壁均能得到高剂量照射,可使单纯放疗效果由30%~40%增至60%以上;③腔内后装放射治疗。剂量:现在采用高剂量率及中剂量率,摒弃低剂量率。高剂量率:Ⅰ期:A点(位于子宫旁三角区内,代表宫旁正常组织受量)总剂量36~40Gy,F点(位于宫腔放射源的顶端旁开子宫中轴2cm,代表肿瘤部受量)总剂量40~45Gy。腔内治疗分5~6次进行,每周1次,每次剂量大致相同。Ⅱ期~Ⅲ期:A点及F点总剂量均为45~50Gy,腔内治疗分6~7次,每周1次,每次剂量大致相同。中剂量率:Ⅰ期:A点总剂量率45~50Gy,F点总剂量50~55Gy,腔内治疗6~8次,每周1次,每次剂量基本相似,Ⅱ~Ⅲ期:A点及F点剂量均为55~60Gy,腔内治疗7~8次,每周1次,每次剂量大致相同。腔内照射多用137Cs、60Co等。
