Treatment, Prospective, Assignment, Open Label, Single-center, Non-randomized Study An exploratory clinical trial of comparison of Nab-Paclitaxel combined with Gemcitabine and Gemcitabine combined with Tegafur for adjuvant chemotherapy after radical resection of pancreatic cancer
详细描述
Pancreatic cancer has an extremely poor prognosis with a 5-year survival rate of less than 5%. About 25% of patients have the opportunity for radically surgical resection when diagnosis. However, the recurrence rate is up to 85% within 2 years. Data from clinical trials indicated that gemcitabine-based adjuvant chemotherapy reduced recurrence and enhanced overall survival for patients who have undergone surgery to remove their tumor. Nab-paclitaxel could significantly increase the concentration of gemcitabine in the tumor; recent studies showed that nab-paclitaxel plus gemcitabine significantly improved progression-free survival and overall survival of metastatic pancreatic cancer patients. A study in Japan and Taiwan compared the efficacy of gemcitabine in combination with tegafur in patients with locally advanced or metastatic pancreatic cancer. The median progression-free survival was significantly better in the gemcitabine combined with the tegafur group than in the gemcitabine group. The present study is intended to observe the effect of albumin paclitaxel combined with gemcitabine and tegafur combined with gemcitabine on recurrence-free survival in patients with pancreatic adenocarcinoma undergoing radical resection.
