EP397 Clinical contribution of antecedent ligation of uterine vessels in radical hysterectomy to the prognosis of patients with uterine cervical cancer

e17024 Background: A multicenter phase II trial was conducted to assess the efficacy and toxicity of paclitaxel and nedaplatin as the initial postoperative adjuvant chemotherapy for high-risk uterine cervical cancer. Methods: The patients with FIGO stages IB1-IIA2 squamous cell carcinoma of the uterine cervix were enrolled. Histologic confirmation of lymph node metastasis was mandatory. Intravenous paclitaxel 175 mg/m(2) over 3hours and nedaplatin 80 mg/m(2) over 1 hour were administered on day 1 of a every 28 day cycle, of which there were 5 cycles after radical hysterectomy. Results: 62 patients were enrolled into the study protocol from November 2011 to July 2015. The median age of patients was 48.5 years (range; 28-64). Median tumor diameter was 37 mm (0-34). 10 patients (16.1%) had parametrial invasion, 44 (71.0%) had deep stromal invasion, and 53 (85.5%) had lymph-vascular invasion. 30 patients (48.4%) had one metastatic lymph node, 11 (17.7%) had two, 3 (4.8%) had three, 5 (8.1%) had four and 13 (21.0%) had five or more. With a median follow-up of 36.9 months (range: 17.2-61.5), the 2-year progression-free survival rate and pelvic disease progression-free rate were 78.9% (95% CI, 68.5% to 89.3%) and 85.0% (95% CI, 75.8% to 94.3%), respectively. The 2-year overall survival rate was 93.3% (95% CI, 86.8% to 99.8%). Adverse events were almost acceptable. Grade 3-4 adverse events (NCI-CTC ver4.0) that occurred in 5% or more patients were neutropenia (60.7%) and infection (6.6%). The proportion of patients who completed 5 cycles of treatment was 90.3%. Conclusions: Adjuvant chemotherapy with paclitaxel and nedaplatin for patients with high-risk cervical cancer after radical hysterectomy was demonstrated to be an effective and feasible treatment. Phase III trial should compare this with concurrent chemoradiotherapy. Clinical trial information: 000005605.

The objective of this study is to describe a technique for preserving the autonomic nerve systematically, including the hypogastric nerves, pelvic splanchnic nerves, and pelvic plexus and its vesical branches, based on anatomic considerations for the autonomic nerves innervating the urinary bladder, in radical hysterectomies and to assess postsurgical bladder function. A nerve-sparing radical hysterectomy was carried out on 27 consecutive patients with uterine cervical cancer treated between 2000 and 2002. The FIGO stages of the disease consisted of 10 stage Ib1, 6 stage Ib2, 3 stage IIa, and 8 stage IIb. The nerve-sparing procedure was successfully completed in 22 of the 27 patients (81.5%) in the study. At 1 year after the operation, bladder symptoms were significantly improved in the nerve-sparing group compared to the non–nerve-sparing group. Urinary incontinence and abnormal (diminished) bladder sensation were observed in three of the five patients (two patients had both symptoms), for whom the nerve-sparing procedure could not be performed, but none of the 22 patients for whom the nerve-sparing procedure was performed had incontinence, and only two patients had abnormal (increased) bladder sensation (P = 0.0034 for incontinence and P = 0.030 for abnormal bladder sensation). The patients' survival was not adversely affected by the nerve-sparing procedure. Although it is still preliminary, the surgical technique described in this report is thought to be effective for preserving bladder function, and thus, the quality of life could be improved for patients with cervical cancer who are treated with a radical hysterectomy. For further evaluation of the efficacy of nerve-sparing radical hysterectomy, a prospective randomized trial needs to be performed.
