Abstract
Active hexose-correlated compound (AHCC) is a standardized extract from cultured Lentinula edodes mycelia, used as a potent biological response modifier in cancer treatment. We evaluated the nutritional effect of AHCC, given during neoadjuvant therapy, to patients with pancreatic ductal adenocarcinoma (PDAC). Thirty patients with resectable or borderline-resectable PDAC received neoadjuvant therapy with gemcitabine plus S-1. We compared, retrospectively, the outcomes of 15 patients who received AHCC combined with neoadjuvant therapy with those of 15 patients who did not receive AHCC combined with neoadjuvant therapy. The median changes of the neutrophil-to-lymphocyte ratio (NLR) and prognostic nutrition index (PNI) were significantly better in the AHCC group. The relative dose intensity of neoadjuvant therapy was also significantly higher in the AHCC group. Thus, AHCC may improve the nutritional status during neoadjuvant therapy of patients with pancreatic ductal adenocarcinoma. To validate these results and examine the long-term impact of AHCC, a prospective phase II study for PDAC is ongoing.
