e14656 Background: Gastric cancer (GC) contributes significantly to the burden of cancer death in the United States. Unfavorable prognosis in patients with gastric cancer and peritoneal carcinomatosis (GCPC) is well-documented. In this study, a model predictive of GCPC is proposed, and outcomes in patients with GCPC treated with surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) are assessed. Methods: A single-institution analysis of 112 patients treated for GC between the years 2000 and 2011 was performed. Demographic and clinical-pathologic criteria were entered into univariate and multivariate analyses, to identify criteria independently predictive of GCPC. Overall survival in each cohort was determined via Kaplan-Meier analysis. Results: GCPC developed in 28/112 (25%) of GC patients. Several variables were associated with GCPC by univariate analysis (age, p = 0.018; tumor stage, p = 0.004; tumor location, p = 0.046), but only age (≤60) and tumor stage (T3/T4) were independently predictive of GCPC by multivariate analysis (HR = 3.949, p = 0.024; HR = 3.942, p = 0.049, respectively). Intermediate-term survival was not significantly impacted in nine GCPC patients treated with HIPEC (65% 1-year, 39% 3-year without HIPEC; vs. 73% 1-year, 39% 3-year with HIPEC, p = NS). Conclusions: A model to identify gastric cancer patients at highest risk for GCPC is proposed. Although intermediate term survival in a small number of GCPC patients (9) treated with HIPEC is not significantly improved, emerging experience with increased follow-up with HIPEC in larger cohorts is needed. Earlier application of HIPEC targeted at patients at highest risk may be feasible in utilizing a model predictive of GCPC.

AbstractBackground: The current treatment of choice for peritoneal carcinomatosis from gastric cancer is systemic chemotherapy. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is a new aggressive form of loco-regional treatment that is currently being used in pseudomyxoma peritoneii, peritoneal mesothelioma and peritoneal carcinomatosis from colorectal cancer. It is still under investigation for its use in gastric cancer.Methods: The literature between 1970 and 2016 was surveyed systematically through a review of published studies on the treatment outcomes of CRS and HIPEC for peritoneal carcinomatosis from gastric cancer.Results: Seventeen studies were included in this review. The median survival for all patients ranged from 6.6 to 15.8 months. The 5-years overall survival ranged from 6 to 31%. For patients with complete cytoreduction, the median survival was 11.2 to 43.4 months and the 5-years overall survival was 13 % to 23%. Important prognostic factors were found to be a low peritoneal carcarcinomatosis index (PCI) score and the completeness of cytoreduction.Conclusion: The current evidence suggests that CRS and HIPEC has a role to play in the treatment of peritoneal carcinomatosis from gastric cancer. Long term survival has been shown for a select group of patients. However, further studies are needed to validate these results.

Abstract Background There is no currently available treatment for peritoneal metastasis of gastric cancer. This phase II study aimed to evaluate the efficacy and safety of neoadjuvant systemic chemotherapy and hyperthermic intraperitoneal chemotherapy (HIPEC) combined with cytoreductive surgery (CRS) for the treatment of these patients. Methods Neoadjuvant chemotherapy comprised two cycles of HIPEC and four cycles of S-1 plus paclitaxel. HIPEC was administered intraperitoneally with paclitaxel (75 mg/m2). For systemic chemotherapy, paclitaxel was administered intravenously(150 mg/m2) on day 1, and S-1 was administered orally(80 mg/m2/day)on days 1–14 of a 3-week cycle. Another two cycles of HIPEC and four cycles of S-1 plus paclitaxel were administered after second diagnostic staging laparoscopy or CRS. The primary endpoints were treatment efficiency and safety; the secondary endpoint was 3-year overall survival (OS). Results A total of 40 patients were enrolled and 38 patients have been analyzed. Of these, 18 (47.4%) patients received neoadjuvant systemic chemotherapy, HIPEC and CRS (conversion therapy group), while 20 patients received only chemotherapy and HIPEC (palliative chemotherapy group). Median OS was markedly improved in the conversion therapy group (21.1 months, 95% confidence interval [CI] 16.7–25.6 months) in comparison with the palliative chemotherapy group(10.8 months, 95%CI 7.3–14.2 months, p = 0.002). After neoadjuvant systemic chemotherapy and HIPEC, a second laparoscopic exploration was performed, and the prognosis of patients with low peritoneal cancer index (PCI) (PCI < 6) was significantly better than that of patients with high PCI (PCI ≥ 6)(20.1 vs.11.3 months, p = 0.006). Conclusion Neoadjuvant systemic chemotherapy and HIPEC combined with CRS is safe and feasible, and could potentially improve the prognosis of gastric cancer patients with limited peritoneal metastasis. However, further clinical trials are still warranted. Trial registration This study has been registered with ClinicalTrials.gov as NCT02549911. Trial registration date: 15/09/2015.
