Age Influences Likelihood of Pancreatic Cancer Treatment, but not Outcome

Abstract

Background Pancreatic cancer (PanCA) is predominantly diagnosed in elderly patients; nevertheless, a significant number of young patients are affected. We hypothesized more aggressive treatment of young PanCA patients would result in better overall survival (OS). Methods A retrospective review of our institutional cancer database identified subjects for inclusion. Age 50 years was selected to stratify patients into age groups. Results Of 309 PanCA patients, 54 (17%) were ≤ 50 years old. Exocrine cancer was the most common histology (90%). Patients ≤ 50 years old were more likely to have endocrine cancer (22% vs. 7%, P = 0.001). There was no difference in stage or curative intent surgery between age groups. Despite patients ≤ 50 years old receiving more chemotherapy (61% vs. 41%, P = 0.007) and radiotherapy (28% vs. 15%, P = 0.03), there was no difference in OS (24.1 months vs. 14.1 months, P = 0.08). When only exocrine cancers were considered, there was no difference between young and old patients regarding stage, grade, location or surgery. Exocrine cancer patients ≤ 50 years old received more chemotherapy (67% vs. 42%, P = 0.003) and radiation therapy (36% vs. 17%, P = 0.004), but there was no difference in OS. Conclusions A substantial number of PanCA patients are ≤ 50 years old. Patients ≤ 50 years old received more treatment but did not have improved OS. Significant improvements in PanCA survival await development of new treatment strategies.
