The aim of this clinical trial is to assess the oncologic safety of minimally invasive pelvic exenteration in patients with recurrence or persistence of cervical or vaginal cancer with pelvic location, suitable for pelvic exenteration according to the ESGO guidelines (European Society of Gynecological Oncology). The primary aim is to assess the 3-year disease-free survival (DFS). The secondary aim is to assess the 3-year overall survival (OS), the intraoperative and post-operative complication rate, and the patient's quality of life.

Patients will be considered pre-operatively eligible in case of recurrence/persistence of cervical or vaginal cancer with pelvic location, suitable for pelvic exenteration according to the ESGO guidelines (European Society of Gynecological Oncology). Histological diagnosis of recurrent or persistent disease obtained with biopsy performed during examination under anesthesia or US-guided biopsy, or RECIST 1.1 (Response Evaluation Criteria in Solid Tumors) criteria of progressive disease are required, as by standard clinical practice. All patients will undergo MRI pelvic scan and PET/CT scan within one month before the surgery, as by standard clinical practice. After obtaining oral and written informed consent, patients will be registered. Pelvic exenteration will be performed with the aim of removing a single specimen with negative surgical margins.

A mini-laparotomy of up to 7 cm will be allowed to complete the reconstructive phase of the procedure.

Registration data has to be entered to an electronic Case Report Form (eCRF). The Principal Investigator (PI) of the study will independently take responsibility for the development of an electronic Case Report Form (CRF) for data collection.

Exclusion Criteria:

• Para-aortic lymph nodes with a short-axis diameter ≥ 15 mm on MRI scan and/or SUV max ≥ 2.5 on PET/CT scan
• Involvement of lateral pelvic structures (on preoperative imaging or during examination under anaesthesia)
