The pathology report card of stomach cancer can be divided into two kinds, one is the biopsy pathology report of gastroscopy and the other is the tumor surgical resection pathology report of stomach cancer. According to the pathology report card of gastric cancer biopsy, malignant tumor cells can be seen in the microscopic biopsy tissue, and according to the differentiation type of cell nuclei, the diagnosis of the pathology report card can be highly differentiated, low differentiated, moderately differentiated, some of them are imprinted cell carcinoma, and some of them are undifferentiated carcinoma. If the biopsy is only inflammatory, the pathology report card suggests chronic inflammation of the mucosa. The pathology report card of tumor resection after surgery should specifically describe the location of the tumor in the stomach, the size of the tumor, the level of tumor invasion into the gastric wall, and whether there is any cancer embolism in the surrounding nerves, blood vessels, and lymphatic vessels. There are no cancer cells left in the margins of surgery and the greater omentum, how many lymph nodes sent for examination are metastatic and how many are not, and whether immunohistochemistry results, such as CK20, Her-2, KI-67, etc., are positive or negative.
