Stage 2a gastric cancer is a wrong way of expression, the correct one should be stage IIA gastric cancer, which indicates that gastric cancer is in the early to middle stage and can be classified into three kinds of conditions according to the depth of tumor infiltration and lymph node metastasis, etc. The treatment of stage IIA gastric cancer mainly focuses on surgical treatment.
Pathological staging of stage IIA gastric cancer includes the situation that the tumor has infiltrated into mucosa or submucosa, with 3-6 regional lymph nodes metastasis above one centimeter from the primary focus; the tumor has infiltrated into the intrinsic muscular layer of gastric sinus and is accompanied by 1-2 regional lymph nodes metastasis; the tumor has infiltrated the plasma membrane without lymph node metastasis, and has not been seen to invade the surrounding tissues structures and organs.
The main treatment mode of gastric cancer stage IIA is surgical treatment, and postoperative chemotherapy can be assisted with a high 5-year survival rate. Patients should seek medical treatment in time and follow the doctor’s prescription for standardized treatment.
