If stomach cancer metastasizes to ovary after surgery, usually no further surgery can be performed. After stomach cancer surgery, regular review is needed to observe whether stomach cancer recurs or not, and if recurrence occurs, it is necessary to judge whether there are lymph nodes and distant metastasis, so as to judge the seriousness of the disease and then decide how to treat it. If ovarian metastasis occurs, it indicates advanced gastric cancer, and since surgery cannot completely remove the tumor, it is usually not possible to treat it by surgery, but only by chemotherapy and radiotherapy. In case of malignant tumor or recurrence of malignant tumor after surgery, it is necessary to judge the size of the tumor, lymph nodes and distant metastasis to stage the tumor, and then formulate the treatment plan according to the staging results.
