[Analysis of 16 Cases of Primary Duodenal Carcinoma in Our Hospital].

ABSTRACT

Primary duodenal carcinoma is a rare disease among gastrointestinal malignancies and has little evidence. We evaluated retrospectively the treatment status of 16 cases of primary duodenal carcinoma in our hospital between 2010 and 2019. The median age was 72(58-88)years and 63% of patients were male, and Each stage were Stage 0 in 4 cases, Stage Ⅰ in 1 case, Stage ⅢA in 2 cases, Stage ⅢB in 3 cases, and Stage Ⅳ in 6 cases(UICC 8th edition). Initial treatment was endoscopic therapy in 3 cases, surgery in 10 cases, chemotherapy in 1 case, and best supportive care in 2 case. The 2-year survival rate was 51.3% and the MST was 25.4 months in all cases. The Stage 0, Stage Ⅰ cases had all recurrence-free survival, while the Stage ⅢA or higher cases, 2-year survival rate was 33.8% and the MST was 20.0 months. Also, XELOX was often selected as the first-line treatment for chemotherapy regimens including recurrence treatment.
