512例子宫颈癌放射治疗疗效报告

目的 报道512例宫颈癌的治疗结果,寻找提高疗效的途径。方法 对512例子宫颈癌的5年生存率和影响预后的因素进行回顾性分析。结果 放疗后5年生存率分别为Ⅰ期2/2;Ⅱ期74.5％;Ⅲ期56.5％;Ⅳ期28.6％;总的5年生存率为65.4％,与传统腔内治疗的疗效65.7％基本相同,Ⅱ期宫颈病变>4 cm其5年生存率为63.9％;宫颈病变≤4 cm其5年生存率为79.3％(P<0.05),统计学有显著性差异。放疗后放射性直肠炎23例,占4.5％;放射性膀胱炎18例占3.5％。结论 子宫颈癌放射治疗的生存率稳定于65％的水平,改进大宫颈型和分化不好的肿瘤治疗,可能有助提高生存率。

The Radiotherapy Effect of 512 Cases of Carcinoma of Cervix Uteri

Objective: To report treatment results of 512 cases of carcinoma of uteri and investigate the way to improve treatment effects. Methods: The 5-year survival rate and the factors influencing the prognosis of 512 cases of uteri were analyzed retrospectively. Results: The 5-year survival rate after radiotherapy was as follows: stage I: 100%; stage II: 74.5%; stage III: 56.5%; stage IV: 28.6%. Overall 5-year survival rate was 65.4%, which was almost the same as traditional intracavitary injection (65.7%). The 5-year survival rate in cervix lesions more than 4 cm and those less than or equal to 4 cm in stage II was 63.9% and 79.3%, respectively, with statistically significant difference (P<0.05). The 5-year survival rate of the patients with squamous carcinoma in stage II was 77.0% and that with low differentiated squamous carcinoma was 64.0% respectively. Twenty-three (4.5%) out of 512 suffered from post-radiotherapy rectitis, 18 (3.5%) cystitis. Conclusion: the survival rate of the patients with cervix carcinoma subject to radiotherapy is stabilized to 65%. The diameter and pathological classes affect survival rate, respectively. Low radiotherapy dose decrease complications.
