title: Efficacy and safety of intraoperative peritoneal hyperthermic chemotherapy for advanced gastric cancer patients with serosal invasion. A long-term follow-up study.
abstract: OBJECTIVE
  This study was undertaken to investigate the clinical effects and safety of intraoperative peritoneal hyperthermic chemotherapy (IPHC) for advanced gastric cancer (AGC) patients.
  
  
  METHODS
  A total of 118 AGC patients with serosal invasion were enrolled in this study from 1998 to 2001, 52 underwent IPHC after gastrectomy and 66 were treated with gastrectomy only. Among these cases, 96 patients without macroscopic peritoneal metastases were selected for the prophylactic study, 22 with peritoneal metastases were selected for the therapeutic study. Postoperative survival, recurrence pattern and incidences of postoperative complications between patients with and without IPHC were analyzed and compared.
  
  
  RESULTS
  For the prophylactic study, the IPHC procedure improves postoperative survival rate and decrease the incidence of peritoneal recurrence, and is an independent prognostic factor for these patients. For the therapeutic study, postoperative survival times were longer if IPHC was undertaken. No surgery-related death occurred. The incidence of renal dysfunction was higher in the IPHC group, but all patients recovered without hemodialysis.
  
  
  CONCLUSIONS
  IPHC is a safe procedure that improves the survival prognosis for AGC patients with serosal invasion. It is especially beneficial for patients without peritoneal metastasis due to the reduction of postoperative peritoneal recurrence.
