Abstract: Routine therapies for advanced ovarian cancer are as the followings: primary cytoreductive surgery+ platinum based chemotherapy, pathologic  diagnoses by laparoscopy or puncture biopsy,then doing neoadjuvant chemotherapy and interval debulking surgery. Whether to perform a primary cytoreductive surgery is determined by the patient’s tumor load and the risk of postoperative complications which several scoring systems have been developed to predict.We have several predictive scoring systems: Fagotti score, Fagotti-modified score, CT score, Aletti score, PCI score and other scoring systems. Both Fagotti score and Fagotti-modified score under laparoscopy are used to see the probability of optimal cytoreductive surgery. CT score is combined with clinical characteristics to decide whether to perform a primary debulking surgery. Aletti score describes the complexity of a surgery. We also have a score system to predict  postoperative complications. PCI score uses to evaluate tumor load of pelvic cavity and peritoneum. Besides, Anne-Lucie Dessapt presented a R0 prediction model and Eisenkop proposed a five-region prediction model.
