Prognostic value of pretreatment carcinoembryonic antigen after definitive radiotherapy with or without concurrent chemotherapy for squamous cell carcinoma of the uterine cervix.

PURPOSE: To evaluate whether pretreatment carcinoembryonic antigen (CEA) levels have a prognostic role in patients after definitive radiotherapy for squamous cell carcinoma (SCC) of the uterine cervix. METHODS AND MATERIALS: A retrospective study of 550 patients was performed. The SCC antigen (SCC-Ag) and CEA levels were regarded as elevated when they were ≥2 and ≥5 ng/mL, respectively. A total of 208 patients underwent concurrent chemoradiotherapy (CCRT). The Kaplan-Meier method was used to calculate the distant metastasis (DM), local failure (LF), disease-free survival (DFS), and overall survival (OS) rates. Multivariate analysis was performed using the Cox proportional hazards model. The hazard ratio (HR) with 95% confidence interval (CI) was evaluated for the risk of a poor prognosis. RESULTS: Compared with the patients with normal CEA/SCC-Ag levels, CEA levels ≥10 ng/mL but without elevated SCC-Ag levels was an independent factor for LF (HR, 51.81; 95% CI, 11.51-233.23; p < .001), DM (HR, 6.04; 95% CI, 1.58-23.01; p = .008), DFS (HR, 10.17; 95% CI, 3.18-32.56; p < .001), and OS (HR, 5.75; 95% CI, 1.82-18.18; p = .003) after RT alone. However, no significant role for CEA was noted in patients with SCC-Ag levels ≥2 ng/mL. In patients undergoing CCRT, a CEA level ≥10 ng/mL was an independent factor for LF (HR, 2.50; 95% CI, 1.01-6.21; p = .047), DM (HR, 3.41; 95% CI, 1.56-7.46; p = .002), DFS (HR, 2.73; 95% CI, 1.39-5.36; p = .003), and OS (HR, 3.93; 95% CI 1.99-7.75; p < .001). A SCC-Ag level of ≥40 ng/mL was another prognostic factor for DM, DFS, and OS in patients undergoing not only CCRT, but also RT alone. The 5-year OS rate for CCRT patients with CEA <10 ng/mL and ≥10 ng/mL was 75.3% and 35.8%, respectively (p < .001). CCRT was an independent factor for better OS (HR, 0.69; 95% CI, 0.50-0.97; p = .034). CONCLUSION: Pretreatment CEA levels in patients with SCC of the uterine cervix provide complementary information for predicting LF, DM, DFS, and OS, except for in patients with abnormal SCC-Ag levels before RT alone. More aggressive therapy might be advisable for patients with CEA levels of ≥10 ng/mL.

Characteristics and management of large bowel injury in laparoscopic-assisted vaginal hysterectomy.

STUDY OBJECTIVE: To review laparoscopic-assisted vaginal hysterectomies (LAVH) for large bowel injuries. DESIGN: Retrospective review (Canadian Task Force classification II-2). SETTING: University-affiliated hospital. PATIENTS: Two thousand eighty-four women. INTERVENTION: LAVH. MEASUREMENTS AND MAIN RESULTS: Indications for hysterectomy were myomata uteri, adenomyosis, intractable menorrhagia, endometriosis, severe pelvic adhesions, cervical intraepithelial neoplasia, endometrial polyps, and hyperplasia. Large bowel injuries occurred in six women (2.9/1000), only one of which was recognized postoperatively. Colostomy was performed in four patients, simple repair in one, and laparoscopic repair in one. All these patients were discharged without sequelae. CONCLUSION: In our experience, bowel injury during LAVH was not a common event.
