Irradiation using the afterloading therapy equipment enabling monitored short-term high-dose radiation, not only reduces exposure of the medical staff to radiation, but also places less strain on the patients. 94 patients with endometrial carcinoma were treated by irradiation alone between 1980-1985 and could be followed up for at least 12 months up to 5 years. Evaluation was performed with regard to a recurrence-free survival rate and radiation side effects. The 5-year survival rates with radiation alone are compared with a previously recorded control group. Before the afterloading technique had become available, the 5-year survival for endometrial carcinoma treated by intracavitary radium-226 was 50%. Using the afterloading iridium-192 technique, the 3-year recurrence-free rate was 81% and the 5-year survival rate 70%. There was no difference between younger (50-69 years of age) and older (70-85 years of age) patients, nor was there any difference between highly and less differentiated tumours. Incidence of severe damage caused by radiation in the overall group: 2 cases of ileus, 1 case of rectovaginal fistula, 3 cases of rectal ulcers and 1 case of severe vaginal necrosis. Severe complications did not occur with the optimal intrauterine fraction dose of 850 cGy (4 times) and 700 cGy intravaginal (once), nor could any complications be observed when the total rectal dose did not exceed 500 cGy. In only 5% of the patients the treatment was combined with percutaneous telecobalt irradiation (stage II). Intrauterine and intravaginal applications were performed without anaesthesia or sedation, and outpatient treatment was possible in almost all cases.
使用后装治疗设备进行照射,可实现监测下的短期高剂量放射,不仅能减少医护人员的辐射暴露,还能减轻患者的负担。1980年至1985年间,94例子宫内膜癌患者仅接受了放射治疗,并进行了至少12个月至5年的随访。对无复发生存率和放射副作用进行了评估。将单纯放疗的5年生存率与之前记录的对照组进行了比较。在后装技术出现之前,经腔内镭-226治疗的子宫内膜癌5年生存率为50%。使用后装铱-192技术,3年无复发率为81%,5年生存率为70%。年轻患者(50 - 69岁)和老年患者(70 - 85岁)之间以及高分化和低分化肿瘤之间均无差异。总体组中由放射引起的严重损伤发生率:肠梗阻2例,直肠阴道瘘1例,直肠溃疡3例,严重阴道坏死1例。当子宫内分次剂量最佳为850 cGy(4次)和阴道内为700 cGy(1次)时,未发生严重并发症,当直肠总剂量不超过500 cGy时,也未观察到任何并发症。仅5%的患者治疗联合了经皮远距离钴照射(II期)。子宫内和阴道内应用无需麻醉或镇静,几乎所有病例均可门诊治疗。
