Abstract
BACKGROUND AND OBJECTIVES: Endometrial carcinoma is the most common gynecologic malignancy worldwide. Prognosis of patients with peritoneal carcinomatosis (PC) from endometrial carcinoma is deadly, with an estimated median survival not exceeding 12 months. The objective of this study was to report our experience with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for managing PC from primary and recurrent endometrial carcinoma.
DESIGN AND SETTINGS: A retrospective analysis of 6 patients with PC arising from endometrial cancer, who were managed with CRS and HIPEC at our referral tertiary care center, from November 2010 to August 2013.
MATERIALS AND METHODS: Six patients underwent CRS and HIPEC. CRS was performed using standard peritonectomy procedures and visceral resections directed toward the complete elimination of tumors from abdominopelvic cavity. HIPEC was performed with cisplatin (50 mg/m(2)) and doxorubicin (15 mg/m(2)) and allowed to circulate in abdominopelvic cavity for 90 minutes at 41.0 to 42.2 degrees C.
RESULTS: Two patients with primary endometrial carcinoma and 4 patients with recurrent endometrial carcinoma confined to peritoneal cavity were studied. Complete cytoreduction (CC-0) was achieved in 5 patients. The International Federation of Gynecology and Obstetrics (FIGO) stages and histopathological types were as follows: IB endometrioid adenocarcinomas (n=1), IC mesonephric carcinomas (n=1), IIIA endometrioid adenocarcinomas (n=2), IIIA papillary serous carcinomas (n=1), and IIIC clear-cell carcinomas (n=1). Anastomotic leak (grade I) was the most commonly encountered postoperative complication. Two patients developed grade IV complications due to septicemia and pulmonary embolism. No intraoperative mortality occurred. Postoperatively, all patients received chemotherapy (carboplatin and paclitaxel). In 1 patient, the clear-cell carcinoma histologic lesion relapsed within 6 months; the metastases spread to hepatic, pelvic, and mesenteric lymph nodes, and the patient died 5 months later. One patient with cytoreduction completeness of CC-2 developed hepatic metastases within 3 months and is still alive at a follow-up up 6 months. Remaining patients (n=4) are alive and disease free without evidence of recurrence of follow-ups at 35, 34, 19, and 7 months.
CONCLUSION: CRS and HIPEC are well-tolerated and feasibly promising management modalities in PC from primary and recurrent endometrial carcinoma. Further research is needed for in-depth analysis.
