Abstract
Introduction: Pancreaticoduodenectomy (PD) is the primary curative treatment for periampullary and pancreatic head malignancies. A tumor-free resection margin (R0) is a critical prognostic factor, yet overall survival remains poor. This study aimed to assess overall survival after PD, identify histopathological factors predictive of positive margins, and compare survival between margin-positive and margin-negative patients.
Methods: A retrospective review of a prospectively maintained database was conducted for patients undergoing PD for malignant disease at a tertiary institution from January 2017 to June 2022. Patients with an ECOG status ≤2 were included, while those with benign disease, intraoperative metastases, or palliative procedures were excluded. Standard preoperative imaging was used for resectability assessment. Data on demographics, histopathology, and survival were analyzed using univariate analysis and Kaplan-Meier survival curves.
Results: Of 75 patients who underwent curative resection, 66 were included in the final survival analysis. The margin positivity rate was 10.8%. The most common site of margin involvement was the superior mesenteric artery (SMA) margin. Factors significantly associated with a positive resection margin were higher T-stage (T3) and the presence of perineural invasion (PNI). The mean overall survival was significantly lower in the margin-positive group compared to the margin-negative group (6.0 ± 1.5 months vs. 29.0 ± 2.8 months, p = 0.0004). The overall mean survival for the entire cohort was 26.9 months.
Conclusion: A positive resection margin following pancreaticoduodenectomy is associated with significantly worse overall survival and is strongly linked to advanced T-stage and perineural invasion. However, the dismal survival even in margin-negative patients underscores the aggressive biology of these tumors. Future efforts should focus on better understanding tumor biology, refining surgical approaches, and developing more effective adjuvant therapies.
