Abstract
Objectives There are limited treatment options and no consensus on the management of advanced rare ovarian malignancies. Rare ovarian malignancies can present with peritoneal metastases (PM), featuring a similar presentation to more common ovarian subtypes. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is an effective treatment for PM of non-gynecologic origin and, recently, epithelial ovarian cancer. We evaluated the feasibility of CRS/HIPEC in the management of PM from rare ovarian malignancies and report postoperative outcomes on these patients. Methods A retrospective review of a single center, prospective database (1994-2021) was performed to identify patients with rare ovarian malignancies treated with CRS/HIPEC. Clavien-Dindo 90-day morbidity/mortality and Kaplan-Meier overall (OS) and progression-free survival (PFS) were analyzed. Results Of 44 patients identified, 28 underwent CRS/HIPEC. Six were aborted due to extensive disease. Histologic subtypes included: clear cell (5/28, 17.9 %), endometrioid (5/28, 17.9 %), granulosa cell (3/28, 10.7 %), low-grade serous (6/28, 21.4 %), mesonephric (1/28, 3.6 %), mucinous (6/28, 21.4 %), and small cell (2/28, 7.1 %) carcinomas. Eight (28.6 %) patients had primary and 20 (71.4 %) had recurrent disease. Median peritoneal cancer index (PCI) was 21 (IQR: 6-29). Complete cytoreduction (<2.5 mm residual disease) was achieved in 27/28 (96.4 %). Grade III/IV complications occurred in 9/28 (32.1 %) with one (3.6 %) mortality. After a median follow-up of 65.8 months, 20 patients were alive. Five-year OS and PFS were 68.5 and 52.6 %, respectively. Conclusions In patients with PM from rare ovarian malignancies, CRS/HIPEC is feasible and has an acceptable safety profile. Longer follow-up and multicenter trials are needed.

Abstract
BACKGROUND Most patients with epithelial ovarian cancer (EOC) present with significant peritoneal spread. We assessed collaborative efforts of surgical and gynecological oncologists with expertise in cytoreductive surgery (CRS) in the management of advanced EOC. METHODS Using a prospective single-center database (2014-2022), we described the operative and oncologic outcomes of stage IIIC-IVA primary and recurrent EOC perioperatively managed jointly by gynecological and surgical oncologists both specializing in CRS and presented components of this collaboration. RESULTS Of 199 identified patients, 132 (66 %) had primary and 53 (27 %) had recurrent EOC. Due to inoperable disease, 14 (7 %) cases were aborted and excluded from analysis. Median peritoneal cancer index (PCI) in primary and recurrent patients was 21 (IQR: 11-28) and 21 (IQR: 6-31). Upper abdominal surgery was required in 95 % (n = 125) of primary and 89 % (n = 47) of recurrent patients. Bowel resections were performed in 83 % (n = 110) and 72 % (n = 38), respectively. Complete cytoreduction (CC-0/1) with no disease or residual lesions <2.5 mm was achieved in 95 % (n = 125) of primary and 91 % (n = 48) of recurrent patients. Ninety-day Clavien-Dindo grade III-IV morbidity was 12 % (n = 16) and 21 % (n = 11), respectively. Median follow-up was 44 (95%CI: 33-55) months. Median overall survival in primary and recurrent EOC was 68 (95%CI: 45-91) and 50 (95%CI: 16-84) months. Median progression-free survival was 26 (95%CI: 22-30) and 14 (95%CI: 7-21) months, respectively. CONCLUSIONS Perioperative collaboration between surgical and gynecological oncologists specializing in CRS allows safe performance of complete cytoreduction in the majority of patients with primary and recurrent EOC, despite high tumor burden.
