486 Background: The safety and feasibility of starting S-1 adjuvant chemotherapy for pancreatic cancer has not been evaluated in elderly patients. Methods: The patients who underwent curative D2 surgery for pancreatic cancer were selected to this retrospective study. The patients were diagnosed within stage I to III disease, and received adjuvant S-1 at our hospital. Patients were categorized into two groups; non-elderly patients (age<70 years: group A) and elderly patients (age≥70 years: group B). The toxicity and drug continuation rates in the two groups were compared. Results: Total 40 patients were evaluated in this study. There were no grade 3 and 4 toxicities. The incidences of grade 2 hematological toxicities were 0% in group A and 11% in group B. The incidences of grade 2 non-hematological toxicities were 50% in group A and 27.8% in group B. The differences in both groups were not significant. The continuation rate at 6 months was 55.7% in group A and 72.7% in group B, and there was also no significant difference in the groups. Conclusions: These results suggest that S-1 adjuvant chemotherapy for pancreatic cancer is safe and feasible, regardless of the age of the patient; especially in elderly patients.
