Background: Chemotherapy-induced neutropenia (CIN) may compromise planned chemotherapy, resulting in severe infection, dose reduction or delayed treatment. Orally administered 1-pamitoyl-2-linoleoyl-3-acetyl-rac-glycerol (PLAG) is a synthetic monoacetyldiglyceride, a product found in the antlers of sika deer. The aim of this study was to evaluate the effectiveness of PLAG for the prevention of CIN.

Methods: A total of 48 patients with unresectable pancreatic cancer received gemcitabine-based palliative chemotherapy. Among those patients, 16 patients received PLAG (500 mg) twice daily from the start of chemotherapy to the completion.

Results: The PLAG group showed a significantly lower incidence of neutropenia (absolute neutrophil count < 1,500 cells/mm3, grade 2-4), as compared to the control group (37.5% vs. 81.3%, P < 0.05). The absolute neutrophil counts (ANCs) of the PLAG group significantly less decreased from the baseline level compared to those of the control group (P < 0.05) and this significant difference in the reduction percentage of ANCs between the two groups was sustained throughout the courses of chemotherapy. No adverse events related to PLAG were observed.

Conclusions: PLAG was shown to be clinically effective and safe in reducing the incidence of CIN in pancreatic cancer patients receiving gemcitabine-based chemotherapy.
