Were enrolled patients who met the inclusion criteria by receiving 3 to 4 cycles of NACT, with ca 125 up to 200 U/ml, and partial or complete response by image (PET-CT), and subsequently underwent laparoscopic approach.

The procedure started with the cytoreduction of highest complexity (determined at the time of initial inspection), after which, if necessary, the patient underwent a complete hysterectomy, bilateral salpingo-oophorectomy, omentectomy, or partial peritonectomy and excision of any peritoneal implants present. The magnitude of the surgical procedures will be classified as:

1. Standard surgery: minimal hysterectomy, adnexectomy y omentectomy
2. Radical Surgery: included resection of the ovaries, of the rectouterine excavation (pouch of Douglas) and or the peritoneum between the bladder and uterus, hysterectomy, rectosigmoid colectomy, and complete omentectomy
3. Supra-radical Surgery: included other procedures such as splenectomy, diaphragm resection, or other intestinal resection.

Efficiency of laparoscopic interval surgery will be evaluated according to percentage of patients who achieved optimal cytoreduction compared to the reported rates in the literature (70 -80%) and the measured frequency of complications during the 30 day postoperative period. Severity of complications will be measured using the Clavien Dindo scale (Grade I: any deviation from the normal post operative course without need for pharmacological treatment - Grade V: death)
