Purposes
This study aimed to clarify the impact of postoperative nonalcoholic fatty liver disease (NAFLD) on the clinical course of patients with pancreatic ductal adenocarcinoma (PDAC).
Methods
One hundred and eight patients with pancreatic cancer undergoing pancreaticoduodenectomy (PD) with curative intent in between 2005 and 2016 were enrolled in this study. Post-PD NAFLD was assessed by computed tomography (CT), which was routinely performed at 3 months, 6 months, and 1 year after surgery. The clinical impact of post-PD NAFLD was examined from an oncological perspective.
Results
There were 50 (46.2%) post-PD NAFLD patients. The NAFLD group showed significantly lower CT values at 3 months, 6 months, and 1 year after surgery than those without NAFLD. Patients with NAFLD showed significant body weight loss and a decrease in serum albumin level after surgery compared with those without NAFLD. Consequently, the 70% completion rate of adjuvant chemotherapy with gemcitabine, but not S1, was significantly lower in the NAFLD group than in the non-NAFLD group. The 5-year overall survival and disease-free survival rates were comparable between the two groups.
Conclusion
Post-PD NAFLD was associated with malnutrition in patients with PDAC, reducing their tolerance to gemcitabine-based adjuvant chemotherapy. Post-PD NAFLD needs to be emphasized and requires special nutritional intervention in patients with PDAC.
