The therapeutic impact of completion surgery (hysterectomy) after chemoradiotherapy was investigated in patients with stage IB or II cervical cancer. Hysterectomy had no therapeutic impact in patients with a clinical and radiological complete response after chemoradiotherapy, but this conclusion is limited by the lack of power.

Concomitant chemoradiation (CRT) (including brachytherapy) is considered the standard management for stage IB2 or II cervical cancer in many countries. Nevertheless, some of them discuss completion surgery (hysterectomy [HT]) after CRT. The aim of this study was to investigate the therapeutic impact of such surgery.
A randomized trial was opened in France in 2003 to evaluate the interest in HT after CRT. Inclusion criteria were: (a) stage IB2 or II cervical cancer without extrapelvic disease on conventional imaging; (b) pelvic external radiation therapy (45 Gy with or without parametrial or nodal boost) with concomitant cisplatin chemotherapy (40 mg/m2 per week) followed by uterovaginal brachytherapy (15 Gy to the intermediate risk clinical target volume); and (c) complete clinical and radiological response 6–8 weeks after brachytherapy. Patients were randomized between HT (arm A) and no HT (arm B). Unfortunately this trial was closed because of poor accrual: 61 patients were enrolled (in 2003–2006) and are reported on here.
Thirty one and 30 patients were enrolled, respectively, in arm A and arm B. Twelve patients recurred (five of them died): respectively, eight and four in arm A and arm B. The 3-year event-free survival rates were 72% (standard error [SE], 9%) and 89% (SE, 6%) (not significant [NS]) in arm A and arm B, respectively. The 3-year overall survival rates were 86% (SE, 6%) and 97% (SE, 3%) (NS) in arm A and arm B, respectively.
Results of the current trial seem to suggest that completion HT had no therapeutic impact in patients with clinical and radiological complete response after CRT (but this conclusion is limited by the lack of power).
