Tegeo capsules are mainly used in chemotherapy of gastric cancer with good therapeutic effect, and its main component is fluorouracil derivative. The prognosis of advanced gastric cancer is poor and the survival period is relatively short. Generally, the average survival period of patients with advanced gastric cancer combined with distant metastasis is about 3 months.
