Phase II trial of radical surgery for locally advanced pelvic neoplasia

Background: Reported operative mortality and survival rates following total pelvic exenteration (TPE) for recurrent pelvic neoplasia are now as good as those for many primary treatments. The currently accepted primary treatments for these tumours are, however, still either radiotherapy alone or radiotherapy and chemotherapy. The primary aim of this study was to evaluate the safety and tolerability of TPE and secondarily to ascertain survival after TPE. Methods: This was a phase II study of 50 patients with locally advanced pelvic tumours who underwent TPE. Results: Thirty‐two patients (64 per cent) underwent TPE for recurrent carcinoma of the cervix, seven (14 per cent) for rectal cancer, three (6 per cent) for vulval carcinoma, three (6 per cent) for vaginal carcinoma, two (4 per cent) for prostate cancer and three (6 per cent) for other tumours. The 30‐day mortality rate was 8 per cent with an in‐hospital mortality rate of 16 per cent. The crude morbidity rate was 62 per cent, with 23 patients (46 per cent) having grade III or IV toxicity. A complete response was achieved in 63 per cent and a partial response in 37 per cent of patients. The overall median survival time was 86 weeks; it was 111 weeks in patients in whom a complete response was achieved. Conclusion: The survival and operative mortality rates that are now attainable with TPE are comparable to those achieved with chemoradiotherapy in advanced pelvic neoplasia. TPE should no longer be reserved for salvage therapy and should perhaps be compared with chemoradiotherapy as first‐line treatment in a phase III randomized trial in patients with these tumours. © 1999 British Journal of Surgery Society Ltd
