Methods： Nineteen locally advanced cervical cancer （LACC） patients from November 2003 to November 2005 were analyzed retrospectively. NAIC was administrated 2 courses every 2 weeks using a combination of 30 mg/m^2 bleomycin and 50 mg/m^2 cisplatin via bilateral femur artedes. The response to NAIC was assessed by pelvic examination and imaging diagnostics and histological analysis. Two weeks after NAIC radical hysterectomy with pelvic lymphadenectomy was performed. Results： Radical hysterectomy with pelvic lymphadenectomy were performed in 18 patients successfully. The mean tumor reduction rate was 73.04%. The overall clinical response rate of NAIC was 84.2% with 2 complete responses and 16 partial responses. Only 1 nonresponder. Six of 7 cases who had parametrial infiltration had a absence after chemotherapy, no significant change was observed in 1 case who followed by radiotherapy. Multivariate logistic regression analysis indicated that tumor volume prior to treatment was determining factor affecting the efficacy of NAIC in LACC. Conclusion： pre-operative NAIC inhibited the growth of LACC, minimized the size, eliminate effectively the pathologic dsk factors in the pelvic cavity, to improve the operability in cervical cancer patients with stage lib or above, considered inoperable.展开更多

Methods： Fifty-six cases with cervical cancer （FIGO lib to IVa） were divided randomly into two groups in the oncology hospital of Jingzhou from September 2009 to October 2010, radiotherapy alone （28 cases） and radiation plus chemotherapy （TP） group. There was no difference of radiotherapy between the two groups, the RT ＋ C cases who accepted TP regimen during the radiation, and DDP once weekly injection of vain, according to 20 mg/m2 and taxotere once weekly i.v. according to 35 mg/m2. These regimen were given for 4-5 weeks, and some medicine for vomit- ing was given to the RT ＋ C cases. Two groups were received an oral medicine MA 160 mg every day during the treatment. Results： The early outcome： the complete remission rate was 64.3% and partial remission rate was 35.7% in RT ＋ C. The complete remission rate was 32.1% and partial remission rate was 39.3% in RT. The total response rate and complete remis- sion of RT ＋ C group was higher than that of the RT group. There was significant difference between the two groups. In RT ＋ C group, 1-year survive rate was 100.00% （28/28）; in RT group, 1-year survive rate was 85.71% （24/28）. There was significant difference between the two groups （X2 = 4.31 〉 3.84, P 〈 0.05）. Conclusion： The taxotere and cisplatin chemoradiotherapy can improve the early outcome of the advanced cervical cancer, and the adverse effect are raised, but that can be endured.展开更多
