Irinotecan Liposome in Combination With Capecitabine

Pancreatic cancer is a group of malignant tumors mainly originated from pancreatic ductal epithelium and follicular cells, with high degree of malignancy, insidious onset, difficult early diagnosis, rapid progression, short survival time, and one of the malignant tumors with the worst prognosis, which is known as the "king of cancers". In recent years, the incidence rate of pancreatic cancer has been increasing both at home and abroad. At present, the palliative treatment of advanced pancreatic cancer is still mainly based on chemotherapy, such as FOLFIRINOX regimen.

In a clinical study exploring capecitabine in gemcitabine-treated patients with metastatic or unresectable locally advanced pancreatic cancer, 42 patients received oral capecitabine 1,250 mg/m2 twice daily (2,500 mg/m2/d) as intermittent therapy in 3-week cycles consisting of 2 weeks of dosing followed by 1 week of withdrawal. A total of 4 remissions were achieved in 42 evaluable patients, for an overall remission rate of 9.5%.
