The appearance of liver metastasis after gastric cancer surgery indicates that it is advanced gastric cancer, and the survival period is usually about one year. After gastric cancer surgery, the tumor is prone to recurrence or metastasis, usually liver metastasis or peritoneal implantation metastasis is more common. When liver metastasis appears, the patient may have vague pain or swelling in the liver area, or there may be no symptom but discovered unintentionally during physical examination. If patients have peritoneal metastasis, they may have abdominal pain, paroxysmal pain, or even intestinal obstruction symptoms. When gastric cancer has liver metastasis, it is usually necessary to consider targeted therapy along with chemotherapy for treatment, as it may prolong the overall survival time of the patient. If the liver metastases increase during the treatment process, it means the treatment effect is not good. If the liver metastases decrease or disappear during the treatment process, it means the treatment effect is okay, which can further prolong the survival time of the patient.
