Complications After Extended Radical Resections for Locally Advanced and Recurrent Pelvic Malignancies: A 25-Year Experience.

BACKGROUND

The oncological role of pelvic exenteration for locally advanced and recurrent pelvic malignancies arising from the anorectum, gynaecological, or urological systems is now well-established. Despite this, the surgical community has been slow to accept pelvic exenteration, undoubtedly due to concerns about high morbidity and mortality rates. This study assessed the general major complications and predictors of morbidity following extended radical resections for locally advanced and recurrent pelvic malignancies.

METHODS

Data were collected from prospective databases at two high-volume institutions specialising in beyond TME surgery for locally advanced and recurrent pelvic malignancies between 1990 and 2015. The primary outcome measures were major complications (Clavien-Dindo 3 or above) and predictors for morbidity.

RESULTS

A total of 646 consecutive patients required extended surgery for local advanced pelvic malignancies. The median age was 63 (range 19-89) years, and the majority were female (371; 57.4%). One or more major complications were observed in 106 patients (16.4%). The most common major complications were intra-abdominal collection (43.7%; n = 59/135) and wound infection (14.1%; n = 19/135). The overall inpatient mortality rate was 0.46% (n = 3/646). Independent predictors for major morbidity following surgery for locally advanced or recurrent pelvic malignancies were squamous cell carcinoma of anus, sacrectomy, and blood transfusion requirement.

CONCLUSIONS

This series adds increasing evidence that good outcomes can be achieved for extended radical resections in locally advanced and recurrent pelvic malignancies. A coordinated approach in specialist centres for beyond TME surgery demonstrates that this is a safe and feasible procedure, offering low major complication rates.
