【摘要】：目的探讨宫颈癌放疗后骨盆衰竭骨折的MRI特点、骨折率及相关因素。方法收集176例具有完整临床及盆腔MRI资料的宫颈癌放疗后患者,分为衰竭骨折组及未骨折组,进行统计学分析。结果 176例中,发生骨盆衰竭骨折共15例(15/176,8.52%)。衰竭骨折组与未骨折组间宫颈癌首诊时年龄、月经状况、放疗治疗方式及是否适合手术治疗方面差异均有统计学意义(P均0.05)。两组间体质量指数、FIGO分期、盆腔外放疗的辐射剂量、放疗结束至MR检查的时间间隔差异均无统计学意义(P均0.05)。MRI示15例均累及骶骨,其中4例同时合并第1或2骶椎横行骨折,3例同时累及耻骨或髂骨。Kaplan-Meier曲线图示衰竭骨折5年累积发病率为31.80%。结论宫颈癌放疗后骨盆衰竭骨折好发于骶骨,高龄和绝经状态是其主要危险因素。
[Abstract]:Objective to investigate the MRI features of cervical cancer after radiotherapy of pelvic insufficiency fracture, fracture rate and related factors. Methods 176 cases of patients with cervical carcinoma with complete clinical and pelvic MRI data, divided into failure fracture group and non fracture group were statistically analyzed. Results in 176 cases, a total of 15 cases of fracture of pelvic insufficiency (15/176,8.52%). Failure fracture group and non fracture group first diagnosed cervical cancer age, menstrual status, radiotherapy and surgical treatment methods. There were significant differences between the suitability (P 0.05) between the two groups. The body mass index, FIGO stage, pelvic radiotherapy dose, time interval difference between the end of radiotherapy MR examination showed no statistical significance (P 0.05).MRI showed 15 cases involving the sacrum, 4 cases with first or 2 sacral vertebra fracture, 3 cases involved the pubis or iliac.Kaplan-Meier curve drawing fracture 5 years cumulative failure The incidence of the disease is 31.80%. conclusion the fracture of pelvic failure after cervical cancer radiotherapy is well occurring in the sacrum, the elderly and the menopause are the main risk factors.
