Cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy improves survival in selected patients with peritoneal carcinomatosis from abdominal and pelvic malignancies: results of 21 cases.

摘要

We evaluated the perioperative safety profile and efficacy of cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) in 21 patients with peritoneal carcinomatosis (PC) from gastrointestinal and gynecological cancers. Twenty-one patients with PC (12 gastric cancer, 5 colorectal cancer, 2 ovarian cancer, 1 pseudomyxoma peritonei, 1 malignant mesothelioma) were treated with CRS + HIPEC with hydroxycamptothecin 20 mg and mitomycin C 30 mg in 12,000 mL of normal saline at 43 +/- .5 degrees C for 60 to 90 minutes. Vital signs were recorded for 5 days after surgery. We analyzed the following: local and systemic infections; gastrointestinal function recovery; hematological, hepatic, and renal parameters; wound healing time; adverse events; survival; and quality of life. The PC index was 2 to 33 (median, 11), the duration of operation 4 to 10 h (median, 8 h), and the highest temperature during 5 postoperative days 38.1 degrees C. Two patients developed generalized edema and were successfully treated. Five patients developed hypoproteinemia on day 1 after surgery. All routine blood tests checked at 1 week after surgery were normal. Time of gastric tube removal was 2 to 7 days. Liquid food intake time was 3 to 8 days. Time of removal of stitches was 8 to 18 days. No local or systemic infections, wound disruption, or other clinically important adverse events occurred. The follow-up was 8 to 43 months (median, 22.5 months). Eleven patients died, three survived with tumor, and seven survived free of tumor. CRS + HIPEC was well tolerated in our selected patients with PC, some of whom had improved survival.
