Propensity score matching (PSM) was adopted to reduce selection bias. Kaplan-Meier analyses and Cox proportional hazards models were used to evaluate the impact of demographic and clinical variables on CSS. Temporal trends in incidence by age group were also assessed over the study period.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 4408 patients were included, with 338 in the AYA group and 4,070 in the older adult (OA) group (aged \u2265 40 years). Compared to the OA group, the AYA group had more female patients, earlier clinical staging, lower distant metastasis rates, and higher surgical treatment rates (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.05).

In this observational analysis, after PSM, CSS rates were similar between the two age groups, despite baseline differences before matching. The rising incidence of PanNETs in AYA individuals suggests a need for continued surveillance and personalized management in this young population.<\/jats:p>\n
