Treatment of synchronous peritoneal carcinomatosis from gastric cancer with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy with lobaplatin and docetaxel / 中国肿瘤临床

ABSTRACT

Objective:To evaluate the efficacy and safety of combined cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) with lobaplatin and docetaxel for treatment of synchronous peritoneal carcinomatosis (PC) from gastric cancer. Methods:Fifty patients with synchronous PC from gastric cancer were treated by 52 CRS+HIPEC procedures with 100 mg of lobaplatin and 120 mg of docetaxel in 12000 mL of normal saline at (43 ± 0.5)℃for 60 min. The primary and secondary endpoints were overall survival (OS) and perioperative safety profiles, respectively. Results:At a median follow-up of 22.5 months, the median OS rate was 14.3 (95%CI:7.6-21.0) months, and the 1-, 2-, and 3-year survival rates were 58%, 40%, and 32%, respectively. No perioperative deaths or serious adverse events occurred in 12 cases (23.1%). Multivariate analysis indicated that completeness of cytoreduction, nor-mality of perioperative tumor markers, and adjuvant chemotherapy of more than six cycles were independent predictors for improved survival. Conclusions:CRS+HIPEC with lobaplatin and docetaxel could improve the OS and ensure perioperative safety of patients with synchronous PC from gastric cancer.
