Whether gastric cancer can be cured depends greatly on the stage at which it is discovered. Clinically, if there is no recurrence or metastasis within five years, it is considered cured. The treatment of gastric cancer is primarily surgical. Therefore, for early-stage gastric cancer patients, if a surgeon assesses that curative surgery is feasible, it is recommended to perform a radical surgical resection. For stage I gastric cancer patients, the five-year survival rate after surgical treatment can generally reach over 90%, which is quite effective. However, for those with advanced gastric cancer, it is generally incurable. Treatments, including chemotherapy, targeted therapy, or optimal symptomatic supportive care, aim to alleviate the patient's suffering and extend their life, but generally cannot cure advanced gastric cancer.
