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.
