Irinotecan Liposomes +5-FU/LV Versus Capecitabine in Patients of Recurrence After Resection of Resectable BTC

Irinotecan liposome combined with 5-FU/LV has shown good efficacy and has certain advantages in reducing the adverse reactions of conventional chemotherapy drugs. Adjuvant treatment of high-risk factors after surgery for biliary tract tumors can be further explored and attempted. Therefore, this study intends to conduct an exploratory study comparing oral capecitabine with irinotecan liposome +5-FU/LV for adjuvant therapy in high-risk patients after resection of resectable biliary malignancies, and evaluate the effectiveness and safety of irinotecan liposome +5-FU/LV as adjuvant therapy for high-risk patients after resection of resectable biliary malignancies. So it can provide more treatment options for patients with postoperative adjuvant therapy of biliary tract malignant tumor. The DFS rate one year after surgery for biliary malignancy was assumed to be 51.4% with a maximum response rate of poor efficacy and 71.4% with a minimum response rate of good efficacy. A two-stage design was adopted with α=0.05 and certainty (1-β) =0.8, and Minimax was adopted. If a response occurs in 7 out of 14 patients or less, treatment options are rejected; In the second phase, if 24 or fewer responses occur in 38 patients, the protocol is rejected. A total of 38 samples were designed in two stages. The 1-year DFS rate was at least 65.8% in the total population of the test and control groups.
