Gastric cancer with liver metastasis is relatively serious. Gastric cancer with liver metastasis is called stage IV gastric cancer, which is also called advanced gastric cancer, and usually requires targeted therapy and chemotherapy for treatment, which is also known as conversion therapy. If there is a single nodule in liver, CT or MRI should be done again after treatment for a period of time to understand the size of metastases in liver, whether they are increasing or disappearing, and also to observe whether the tumor of gastric cancer itself has descended, whether the tumor has shrunk and the condition of lymph nodes, etc. If the tumor shrinks and the metastases disappear during the treatment process, there may be a chance for surgery later. If the tumor progresses further and the number of metastases on the liver gradually increases during the course of conversion treatment, the patient may have a life-threatening condition, which is relatively very serious.
