Preoperative concurrent radiation therapy and chemotherapy for bulky stage IB2, IIA, and IIB carcinoma of the uterine cervix with proximal parametrial invasion.

Abstract

PURPOSE: To evaluate toxicity, local tumor control, and survival after preoperative chemoradiation for operable bulky cervical carcinoma. METHODS AND MATERIALS: Between December 1991 and July 2006, 92 patients with operable bulky stage IB2, IIA, and IIB cervical carcinoma without pelvic or para-aortic nodes on pretreatment imaging were treated. Treatment consisted of preoperative external beam pelvic radiation therapy (EBRT) and concomitant chemotherapy (CT) during the first and fourth weeks of radiation combining 5-fluorouracil and cisplatin. The pelvic radiation dose was 40.5 Gy over 4.5 weeks. EBRT was followed by low-dose rate uterovaginal brachytherapy with a total dose of 20 Gy in 62 patients. After a median rest period of 44 days, all patients underwent Class II modified radical hysterectomy with bilateral pelvic lymphadenectomy. Thirty patients who had not received preoperative uterovaginal brachytherapy underwent postoperative low-dose-rate vaginal brachytherapy at a dose of 20 Gy. The mean follow-up was 46 months. RESULTS: Pathologic residual tumor was observed in 43 patients. After multivariate analysis, additional preoperative uterovaginal brachytherapy was the single significant predictive factor for pathologic complete response rate (p = 0.019). The 2- and 5-year disease-free survival (DFS) rates were 80.4% and 72.2%, respectively. Pathologic residual cervical tumor was the single independent factor decreasing the probability of DFS (p = 0.020). Acute toxicities were moderate. Two severe ureteral complications requiring surgical intervention were observed. CONCLUSIONS: Concomitant chemoradiation followed by surgery for operable bulky stage I-II cervical carcinoma without clinical lymph node involvement can be used with acceptable toxicity. Pathologic complete response increases the probability of DFS.
