ABSTRACT
INTRODUCTION:
The PERISCOPE I (Treatment of PERItoneal dissemination in Stomach Cancer patients with cytOreductive surgery and hyPErthermic intraperitoneal chemotherapy) study was conducted to investigate the safety and feasibility of hyperthermic intraperitoneal chemotherapy (HIPEC) in gastric cancer patients with limited peritoneal dissemination. In this study, tumor characteristics and clinical outcome of the patients treated in the PERISCOPE I trial were investigated.METHODS:
Patients who had undergone the full study protocol were selected; that is, preoperative systemic chemotherapy, followed by a surgical procedure consisting of a (sub)total gastrectomy, cytoreductive surgery, and HIPEC with oxaliplatin (460 mg/m2 ) and docetaxel (in escalating doses).RESULTS:
Twenty-five PERISCOPE I patients underwent the full study protocol. Most patients had an ypT3-4 tumor (96%) and the diffuse-type histology was predominant (64%). Seven patients (28%) had a microscopically irradical (R1) resection. In all patients, a complete cytoreduction was achieved. Median follow-up was 37 (95% confidence interval [CI] 34-39) months. Disease recurrence was detected in 17 patients (68%). Median disease-free and overall survival were 12 and 15 months, respectively.CONCLUSION:
In this series of gastric cancer patients with limited peritoneal dissemination who underwent HIPEC surgery, unfavorable tumor characteristics were common. Survival might be encouraging but disease recurrence was frequent. The efficacy of an HIPEC procedure in improving prognosis is currently being investigated in the PERISCOPE II trial.Palavras-chave
