Tegeo capsules are an oral chemotherapy drug, not a targeted drug, but a derivative of fluorouracil, and can be used for adjuvant chemotherapy for gastric cancer, as well as chemotherapy for intestinal cancer. Tegeo may need to be used alone or in combination with intravenous chemotherapy. In case of intravenous chemotherapy, most of them are used in combination with oxaliplatin. Some advanced patients may be in poor health condition and cannot tolerate intravenous chemotherapy, so they can take Tegeo capsules orally alone. The difference between tegeo capsules and targeted drugs is that targeted drugs act on the tumor target, which may have less side effects and better anti-tumor effect; tegeo capsules are mainly absorbed orally and metabolized by blood to reach the whole body to control the development of the disease.
