Backgrounds/Aims: The published data had contradictory information on the role of adjuvant therapy on resected periampullary carcinomas (PACA). The study was performed to evaluate the survival benefit of adjuvant treatment.
Methods: This was a propensity score matched case-control study from a prospectively maintained database from 2004–2019. The study included patients with nonpancreatic PACA who underwent curative resection. The patients (cases) who received adjuvant chemotherapy were compared with patients (controls) who were observed alone after surgery.
Results: Of 510 patients with PACA, 230 patients (cases = 107, controls = 123) formed the unmatched study cohort. After propensity score matching, 140 patients (cases = 70, controls = 70) formed the matched study cohort. The median overall survival (OS) was similar in cases than controls in the unmatched population but doubled non-significantly in cases after matching (unmatched population, 54 months vs. 54 months, p -value = 0.624; matched population, 71 months vs. 36 months, p -value = 0.087). However, the median recurrence-free survival (RFS) was non significantly higher in the control group (unmatched population, 59 months vs. 38 months, p- value = 0.195; matched population, 53 months vs. 40 months, p -value = 0.797). In cox regression analysis, age < 60 years, advanced T stage, and presence of perineural invasion were independent factors for worse RFS, while tumor recurrence was an independent factor for poor OS.
Conclusions: Patients with nonpancreatic PACA may have an OS benefit from adjuvant chemotherapy, and this needs to be validated with large prospective randomized studies.
