- Abstract
Background: Duodenal adenocarcinoma is rare and its prognostic factors remain controversial. In our study, the role of cell-free deoxyribonucleic acid (cfDNA) as prognostic factor in duodenal adenocarcinoma was evaluated., Methods: From June 2003 to July 2021, plasma samples were collected from 41 patients with duodenal adenocarcinoma. Plasma cfDNA was assessed in combination with clinicopathological and biochemical characteristics. Univariate and multivariate analyses were conducted to identify independent prognostic factors for overall survival with a Cox proportional hazards regression model., Results: The 1- and 5-year survival rates of the patients with high plasma cfDNA level (>9288 copies/mL) group were 58.7% and 17.6%, respectively, which were much lower than patients with low cfDNA level (≤9288 copies/mL), with 95.2% and 64.6%. In univariate analysis, high cfDNA level, lymph node involvement, lymphovascular invasion, and tumor stage were associated with decreased survival. When subjected to multivariate analysis, only high cfDNA level showed significance in influencing the overall survival of duodenal cancer., Conclusion: cfDNA analysis is simple and noninvasive. High cfDNA level is a strong independent prognostic factor for decreased overall survival and it should be integrated into clinical care., Competing Interests: Conflicts of interest: The authors declare that they have no conflicts of interest related to the subject matter or materials discussed in this article., (Copyright © 2024, the Chinese Medical Association.)
