Abstract

Background: Pancreatic ductal adenocarcinoma (PDAC) impacts patients in their 60s, but its incidence in younger patients is increasing. We hypothesize that younger patients may have worse oncologic outcomes.

Methods: Patients who underwent curative pancreatic resection for PDAC between January 2011 and December 2021 at a single institution were analyzed. Early-onset pancreatic cancer (EOPC) was defined as pancreatic cancer diagnosed in patients ≤50 years. Clinical and survival outcomes were compared between EOPC and Conventional Onset Pancreas Cancer (COPC).

Results: A total of 1133 patients were identified, 65 (5.7%) were EOPC. Preoperative patient characteristics including sex, smoking status, alcohol habitus, diabetes mellitus, CA 19-9, and neoadjuvant therapy were similar between EOPC and COPC (p > 0.05). EOPC patients were more likely non-white (p = 0.03), had lower ASA scores (p = 0.02) and larger median tumor size (33 vs 28 mm, p = 0.04), but had similar pathological stages and rate of R0 resections (p > 0.05). Postoperative outcomes were similar (p > 0.05). There was no statistically significant difference in overall (HR 0.93, CI 0.64, 1.33; p = 0.68) or recurrence free (HR 1.05, CI 0.75, 1.48; p = 0.77) survival between the EOPC and COPC after adjusting for significant factors.

Conclusion: Patients with EOPC who underwent surgical resection had similar oncological outcomes compared to patients with COPC.
