Indications and long-term clinical outcomes in 282 patients with pelvic exenteration for advanced or recurrent cervical cancer.

OBJECTIVE

The aim of this study was to summarize the clinical experience at our clinic with pelvic exenteration as a treatment for cervical cancer with special regard to the indications and outcomes of specific patient groups.

METHODS

Medical records of 282 women who underwent pelvic exenteration to treat cervical cancer were analyzed.

RESULTS

In total, 70 patients (25%) underwent primary exenteration, and 212 (75%) underwent secondary exenteration. Exenteration was anterior for 14 (5%) patients, posterior for 6 (2%) and total for 262 (93%). The overall survival (OS) of the 282 patients was 41% at 5 years and 37% at 10 years. The disease-free survival at 5 years was 61%. For 133 patients for whom pelvic exenteration was a curative procedure, the OS was 64% at 5 years and 57% at 10 years. For cases of pelvic exenteration as a palliative intervention, the OS was 19% at 5 years and 18% at 10 years. No difference was seen in the OS at 5 years between patients who received primary and secondary operations. No significant difference in the OS was found regardless of whether the patients had positive pelvic lymph nodes, whereas in cases of paraaortic lymph node metastasis, the OS was significantly lower. Out of all of the procedures, 139 (49%) involved no perioperative or postoperative complications. One major complication was reported for 72 (26%) patients, two complications occurred for 42 patients (15%) and more than three complications were noted for 29 (10%) patients.

CONCLUSION

Pelvic exenteration is an effective technique with a high percentage of long-term survivors. To the best of our knowledge, our study involves the largest published number of patients treated with pelvic exenteration for a single gynecological cancer and shows that previous contraindications for pelvic exenteration, such as lymph node metastasis (especially when confined to the pelvic lymph nodes), older age or palliative intent, should be reconsidered.
