It has higher efficacy and can kill tumor cells more effectively. Trastuzumab is suitable for the treatment of malignant tumors such as HER2-positive breast cancer, gastric cancer, and non-small cell lung cancer. Trastuzumab is a monoclonal antibody that contains only trastuzumab. It mainly inhibits the growth and spread of cancer cells by binding to HER2 receptors.
