从1966～1985年,在Iowa大学医院对43例宫颈癌患者采用扩大野照射治疗腹主动脉周围淋巴结转移。其中鳞癌38例,腺癌5例,中位年龄51岁。临床分期:Ⅰ_B期5例;Ⅱ_A期1例;Ⅱ_B期7例;Ⅲ_B期24例;Ⅳ_A期3例;Ⅳ_B期1例;2例为子宫切除术后盆腔复发。42例做了外科手术,其中经腹膜式29例,腹膜外式13例。大部分病人采用外照射加近距离放疗的联合治疗。使用~(60)Co、γ线或4 MV、10MV X线照射。36例使用前后平行对穿野、7例使用四野技术。12例照射野扩大到第12胸椎以上,24例扩大到第1腰椎以上,7例扩大到第2腰椎以上。腹主动脉周围淋巴结的剂量从3960～6000cGy,中位5040cGy。盆腔剂量从3960～6510cGy,中位4800cGy。近距离放疗通常使用镭、剂量从1200～
From 1966 to 1985, 43 patients with cervical cancer at Iowa University Hospital were treated with expanded wild-type radiation to treat abdominal aortic lymph node metastasis. There were 38 cases of squamous cell carcinoma and 5 cases of adenocarcinoma, with a median age of 51 years. Clinical stage: 5 cases of I_B stage; 1 case of II_A stage; 7 cases of II_B stage; 24 cases of III_B stage; 3 cases of IV_A stage; 1 case of IV_B stage; 2 cases of pelvic recurrence after hysterectomy. Forty-two patients underwent surgery, including 29 in the peritoneal type and 13 in the extraperitoneal type. Most patients use combination therapy with external radiation plus brachytherapy. Use ~(60)Co, gamma rays or 4 MV, 10MV X rays. Thirty-six patients were used parallel to the field before and after the use, and 7 were using the SINO technology. Twelve cases were expanded to the 12th thoracic vertebrae, 24 cases to the first lumbar vertebrae, and 7 cases to the second lumbar vertebrae. The dose of abdominal aortic lymph nodes ranged from 3960 to 6000 cGy with a median of 5040 cGy. The pelvic dose ranged from 3960 to 6510 cGy, with a median of 4800 cGy. Brachytherapy usually uses radium and doses from 1200 to
