简要总结
The investigators will conducted a hospital-based cohort study in our 15-year experience with DA aimed at investigating the long-term outcomes of the patients with DA, along with analyzing the impact of the tumor characteristics, operations and adjuvant therapy on survival outcomes.
详细描述
Numerous meta-analyses and systematic reviews have delved into the treatment of DA, yet the majority of the studies retrospective, single-center, and small sample size series, particularly in China. To bridge this knowledge gap, the investigators will conduct a hospital-based cohort study designed to investigate the long-term survival outcomes of the participants with the non-ampulla duodenal adenocarcinoma, and the effects of tumor characteristics, surgery, and adjuvant therapy on survival outcomes.
