Pelvic exenteration for gynaecological tumours: achievements and unanswered questions.

Pelvic exenteration has been used for 60 years to treat cancers of the lower and middle female genital tract in radiated pelves. The mainstay for treatment success in terms of locoregional control and long-term survival is resection of the pelvic tumour with clear margins (R0). New ablative techniques based on developmentally derived surgical anatomy and laterally extended endopelvic resection have raised the number of R0 resections done, even for tumours that extend to the pelvic side wall, which were traditionally judged a contraindication for exenteration. Although mortality has fallen to less than 5%, treatment-related severe morbidity of pelvic exenteration still exceeds 50%, possibly because of compromised healing of irradiated tissue and use of complex reconstructive techniques. The benefits of exenteration for patients who have advanced primary disease or recurrent tumours after surgery, versus those who have chemoradiotherapy, are not proven by results of controlled trials, but can be assumed from retrospective data. Comparative findings are missing, and arguments are unconvincing to favour pelvic exenteration over less extensive treatments and best supportive care for palliation of cancer symptoms in most patients.
