Abstract
Bearing in mind that the open procedure is already validated by multiple studies, the article aims to prove that pelvic exenteration performed in a minimally invasive fashion might offer better survival and to potentially identify prognostic factors for the outcome of these patients. Data regarding past and present classifications and surgical indications are presented. Patient data were collected retrospectively. The most frequent diseases treated with pelvic exenteration, in terms of the hystological type, were gynecological malignancy and squamous cell carcinoma. Recurrent pelvic disease was found in 68.2% of patients. R0 resection was achieved in 72.7% of patients in the MI group, and in 73.7% of patients in the OP group. Peri-operative morbidity was reported to be 56.6% for open surgery, and 18.1% for minimally invasive. Average DFS was 20.15 months, ranging from 1.5 to 70.3 months, while the OS was calculated to be 38.1 months (0.33 - 1508) up until November 2023. Pelvic exenteration is a continuously improving surgical procedure, open approach being favored to minimally invasive one. On the other hand, hospitalization and morbidity are reduced when choosing the latter. R0 and lymph node status are important predictors for overall survival, as well as major early postoperative complications. All in all, pelvic exenteration is still a promising surgical procedure to extend cancer patients' lives.
