Trastuzumab-deruxtecan (T-DXd) is a targeted medication used to treat HER2-positive cancers. It combines an antibody that targets HER2 proteins on cancer cells with a chemotherapy drug. This medication delivers the chemotherapy directly to cancer cells that have high levels of HER2, potentially reducing damage to healthy cells.

Capecitabine is an oral chemotherapy medication that belongs to a class of drugs called antimetabolites. It works by interfering with cancer cell growth. The body converts this medication into a form of fluorouracil that helps stop cancer cells from multiplying.

Bevacizumab is a targeted therapy that works by blocking the formation of new blood vessels that feed tumors. By preventing the growth of these blood vessels, this medication can help slow or stop tumor growth by cutting off the tumor’s blood supply.

Metastatic Colorectal Cancer – A condition where cancer that begins in the colon or rectum spreads to other parts of the body. The disease starts when cells in the large intestine grow out of control and form tumors. As the cancer progresses, malignant cells can break away from the original tumor and travel through the bloodstream or lymphatic system to form new tumors in distant organs, most commonly the liver and lungs. The cancer cells continue to grow and multiply in these new locations, forming additional tumors that affect the function of the invaded organs. This process of cancer spread is what defines the metastatic stage of the disease.
