Hypofractionated adenocarcinoma of the stomach is a type of gastric cancer. Gastric cancer can be divided into highly differentiated, moderately differentiated and hypofractionated according to the degree of cell nuclear division. Hypofractionation means that gastric cancer cells are less differentiated and have a higher differentiation potential. Hypofractionated cancer tumors are highly malignant, fast growing and prone to metastasis. When carrying out treatment, or when conducting tumor risk factor assessment, the risk of recurrence and metastasis is relatively high for hypofractionated tumors, while highly differentiated cancer cells are already plastic and have already taken shape, with relatively low malignancy. If the test is hypofractionated gastric cancer, its risk stage is higher. Sometimes if the same tumor, some are highly differentiated and some are poorly differentiated, it may be that the highly differentiated tumor does not need further follow-up treatment, while the poorly differentiated still needs further chemotherapy and adjuvant treatment to prevent the tumor from recurrence and metastasis. To assess the stage of tumor, we need to evaluate various aspects, including the size of the tumor, whether there is metastasis in lymph nodes, local infiltration, whether there is cancer embolism in the vasculature, whether there is nerve invasion, and age, which should be considered together.
