Objectives
Narrative objectives1
Patients with stage IIIB-IIIC ovarian cancer with extensive peritoneal dissemination are eligible. We will evaluate the efficacy of total parietal peritonectomy (TPP) in primary debulking surgery (PDS) when complete surgery (no macroscopically residual disease) is performed with multiple organ resection to determine whether TPP improves prognosis . At the same time, we will evaluate the safety of TPP in terms of complications.
If this Phase II study shows that TPP may be effective and the safety profile is acceptable, we will proceed to phase III study.

Key inclusion criteria
* Primary diagnosis of ovarian cancer FIGO stage IIIB-IIIC
* Macroscopic complete resection is possible with PDS based on preoperative examination, staging laparoscopy, and intraoperative findings during PDS
* Histology is diagnosed as High Grade Serous Carcinoma or Endometrioid Carcinoma by tissue biopsy during staging laparoscopy
* Patients who have given their signed and written informed consent
* Age: 18 - 70 years
* Good performance status (ECOG 0/1)
Key exclusion criteria
* Borderline tumors
* There are suspicious lymph nodes (bulky nodes) in preoperative examination and intraoperative findings and systematic retroperitoneal lymphadenectomy is required
* Secondary invasive neoplasms in the last 5 years (However, it is permissible if the possibility of recurrence within 2 years after registration is sufficiently low)
* Neoadjuvant chemotherapy
* Any significant medical reasons, age or performance status that will not
allow to perform the study procedures
* Dementia or significantly altered mental status that would prohibit the understanding and giving of informed consent
