Cardia cancer T2N0M0 is mainly treated by surgical resection, which can be supplemented by radiotherapy and chemotherapy. Cardia cancer T2N0M0 is based on tumor TNM staging in the standard, which indicates that the tumor volume is more than 3 cm but less than 7 cm, and there is no metastatic spread of lymph nodes and distal organs for the time being, which belongs to the early stage, and it can be treated by radical surgery, through which the tumor can be resected, and most of the patients can be clinically cured after the surgery. If the patient does not tolerate surgery or refuses surgery, radical radiotherapy is also feasible. For patients with high risk of recurrence and metastasis, 2-4 cycles of consolidation radiotherapy and chemotherapy are needed to remove the possible residual cancer cells and reduce the chance of recurrence in the later stage.
