Posterior pelvic exenteration for ovarian cancer: surgical and oncological outcomes.

OBJECTIVE: Posterior pelvic exenteration (PPE) can be required to achieve complete resection in ovarian cancer (OC) patients with large pelvic disease. This study aimed to analyze morbidity, complete resection rate, and survival of PPE. METHODS: Ninety patients who underwent PPE in our Comprehensive Cancer Center between January 2010 and February 2021 were retrospectively identified. To analyze practice evolution, 2 periods were determined: P1 from 2010 to 2017 and P2 from 2018 to 2021. RESULTS: A 82.2% complete resection rate after PPE was obtained, with rectal anastomosis in 96.7% of patients. Complication rate was at 30% (grade 3 in 9 patients), without significant difference according to periods or quality of resection. In a binary logistic regression adjusted on age and stoma, only age of 51-74 years old was associated with a lower rate of complication (odds ratio=0.223; p=0.026). Median overall and disease-free survivals (OS and DFS) from initial diagnosis were 75.21 and 29.84 months, respectively. A negative impact on OS and DFS was observed in case of incomplete resection, and on DFS in case of final cytoreductive surgery (FCS: after ≥6 chemotherapy cycles). Age ≥75-years had a negative impact on DFS for new OC surgery. For patients with complete resection, OS and DFS were decreased in case of interval cytoreductive surgery and FCS in comparison with primary cytoreductive surgery. CONCLUSION: PPE is an effective surgical measure to achieve complete resection for a majority of patients. High rate of colorectal anastomosis was achieved without any mortality, with acceptable morbidity and high protective stoma rate.

Empty pelvis syndrome: the use of breast prosthesis in the prevention of complications.

AIM: Empty pelvis syndrome and radiation-induced bowel injury are two major clinical issues resulting from the pelvic dead space after pelvic exenteration (PE). In order to avoid these complications, different methods of pelvic floor reconstruction have been proposed. We report our experience on the use of breast prosthesis. METHOD: Fifty-three patients who underwent PE and three who underwent palliative surgery with silicone breast prosthesis placement were included. RESULTS: Forty-seven posterior PE, six total PE and three palliative procedures were identified. Sphincter preservation was feasible in 34 patients (62.3%). There were no deaths. Overall morbidity was 37.5%. There were no complications such as sepsis or obstruction related to the prosthesis. Adjuvant radiotherapy was delivered in 16 cases (30.1%) without any side-effects. Reconstruction of intestinal continuity was possible in 12 patients (36.3%) with sphincter preservation and the prosthesis allowed a prompt identification of the rectal stump. CONCLUSION: Breast prosthesis placement is a simple and safe method to minimize complications resulting from empty pelvis syndrome and can be adopted to exclude bowel loops from the radiation field. Reconstruction of intestinal continuity after resection is also simplified.

Effects of Neoadjuvant Chemotherapy Plus Radical Surgery as Front Line Treatment Strategy in Patients Affected by FIGO Stage III Cervical Cancer.

BACKGROUND: To assess the clinical efficacy and prognostic outcome of neoadjuvant chemotherapy (NACT) plus radical surgery (RS) as front line treatment in patients with FIGO stage III cervical cancer (CC). METHODS: In this retrospective study, 52 FIGO stage III CC patients treated from 2005 to 2015 were included. All patients received platinum-based chemotherapy. Patients reporting clinical response or stable disease after NACT underwent to RS and bilateral systematic pelvic lymphadenectomy with or without aortic lymphadenectomy or anterior exenteration. Patients with progressive disease underwent palliative management. RESULTS: After NACT, clinical response was observed in 23 patients (44 %): 4 (7.7 %) complete and 19 (36.5 %) partial responses, respectively. Also, 15 patients (28.8 %) had stable disease and 14 (26.9 %) showed disease progression. RS was performed in 40 cases (76.9 %): respectively, 28 (70 %) and 7 (17.5 %) underwent type C2 and D radical hysterectomy, while 5 patients (12.5 %) underwent anterior exenteration. At pathological evaluation, 23 patients (57.5 %) had positive pelvic nodes and 4 (10 %) also had positive aortic nodes. In 6 patients (15 %), moderate-severe (G3-G5) complications occurred. A total of 27 patients (67.5 %) received adjuvant therapy: 16 patients (40 %) received chemotherapy, 10 (25 %) received chemoradiation and 1 (2.5 %) received radiotherapy. Disease relapse occurred in 24 cases (60 %). After follow-up period of 60 months, the median OS of the whole population included was 37 months. Among the 40 surgically treated patients, median OS and DFS were 48 and 23 months, respectively. CONCLUSIONS: NACT plus RS represent a valid alternative with acceptable morbidity for patients with stage III CC.
