Introduction: Ampullary cancer is a periamullary neoplasia with a low incidence but a high mortality rate. This study aimed to assess the impact of ampullary characteristics on overall survival and disease-free survival.
Methods: Retrospective study of 40 patients diagnosed with ampullary cancer who underwent radical cephalic duodenopancreatectomy between 2009 and 2019. We analyzed survival using Kaplan-Meier curves and non-parametric tests, with significance set at p<0.05.
Results: The median overall survival was 41 months (0-154), with a survival rate of 75%, 44%, and 31.6% at 1, 5, and 10 years post-surgery, respectively. The median disease-free survival was 15 months (0-154). Factors impacting overall survival included perineural invasion (p=0.016), pathological N stage (p<0.01), and the number of invaded lymph nodes (p=0.043). Factors influencing disease-free survival were age at surgery (p=0.009), preoperative total bilirubin level (p=0.018), and hematocrit level (p=0.039).
Conclusion: This study represents a series of ampulloma cases studied in Portugal, reflecting overall and disease-free survival, and confirming the aggressiveness of this rare tumor.
