Capecitabine is an innovative drug in the field of chemotherapy, it has a positive effect in the treatment of colorectal cancer, breast cancer and gastric cancer. Capecitabine itself does not have the ability to kill, only after the activation of TP enzymes in the body, can be transformed into a lethal drug. Because the activity of TP in cancer cells is very high, and the activity of TP in normal tissues is lower, so the capecitabine was activated in cancer cells, the cancer cell killing giant in normal cells is only a small amount of activation, damage of normal cells is very small, the adverse reaction is greatly reduced the.
