This clinical trial is focused on studying the effects of a treatment for patients who have undergone surgery for two types of cancer: cholangiocarcinoma and muscle invasive gallbladder carcinoma. Cholangiocarcinoma is a cancer that occurs in the bile ducts, which are small tubes that carry bile from the liver to the small intestine. Muscle invasive gallbladder carcinoma is a type of cancer that affects the gallbladder and has spread into the muscle layer. The treatment being studied involves the use of two medications, gemcitabine and cisplatin, which are given after surgery to help prevent the cancer from coming back. These medications are compared to the standard care, which may include observation or another medication called capecitabine.
The purpose of this study is to evaluate how effective the combination of gemcitabine and cisplatin is compared to the standard care in preventing the return of cancer after surgery. Patients participating in the study will receive either the combination of gemcitabine and cisplatin or the standard care, which could be observation alone or capecitabine, depending on the stage of their cancer. The study will monitor patients over a period to see how well the treatment works in keeping the cancer from returning and to assess the overall health and quality of life of the patients.
Participants in the study will receive treatment for a set period, and their health will be closely monitored by healthcare professionals. The study aims to provide valuable information on the best treatment options for patients who have had surgery for cholangiocarcinoma or muscle invasive gallbladder carcinoma. By comparing the new treatment with the standard care, researchers hope to find the most effective way to help patients live longer without the cancer returning.
