PMID 24394088

Abstract

Eicosapentaenoic acid-enriched oral nutritional supplements (Prosure®; Abbott Japan, Tokyo, Japan) may attenuate surgical stress and catabolism after gastric cancer surgery. The present study aimed to evaluate the effects of Prosure® on body weight loss( BWL) and compliance with S-1 adjuvant chemotherapy after gastrectomy. Patients who underwent curative total gastrectomy for gastric cancer were selected to undergo adjuvant S-1 chemotherapy at Kanagawa Cancer Center between December 2010 and October 2011. The patients received a normal postgastrectomy diet and two 240 mL packs of Prosure® for 21 postoperative days. BWL was defined as %BWL and calculated as %BWL=(preoperative body weight-1-month postoperative body weight)×100/preoperative body weight. Time to S-1 treatment failure was calculated. Five patients were enrolled in this study. The median age was 62.0 years. One patient was male, and 4 were female. The 1-month postoperative BWL was 92.1%. Compared to our previous report, a 20% risk reduction was observed in this study (Prosure® group vs control group, 92.1% vs 89.7%). Moreover, all the patients continued with the S-1 adjuvant chemotherapy for longer than 6 months. Prosure® may inhibit BWL at 1 month after gastrectomy. Moreover, Prosure® improved the patients' compliance with the adjuvant chemotherapy after gastrectomy.
