In three cases, there was disagreement between the lymph node staging according to the JGCA and to the American Joint Committee on Cancer (AJCC).
Lymph node staging according to the American Joint Committee on Cancer (AJCC) and the Japanese Gastric Cancer Association (JGCA), and lymphatic chains involved, number of lymph node metastases, and skip metastasis in patients with gastric carcinoma who underwent surgical resection with curative intent (n=12) at the Clinical Hospital of the Federal University of Minas Gerais, Brazil.
According to the standard criteria of the Japanese Gastric Cancer Association (JGCA) guidelines [5,6], we can resect tumors by the use of ESD, which satisfied the following criteria: (1) confined to the mucosa, (2) less than 2 cm in diameter, (3) without intramural ulcers, and (4) histologically differentiated.
Histologic types were divided into differentiated type and undifferentiated type based on the criteria of the Japanese Gastric Cancer Association (JGCA) .
Tumor size is another factor that can be evaluated in gastric cancer patients, although it is not listed in the staging systems of the UICC or JGCA
for gastric cancer [9,10].
The clinicopathological features such as tumor size, tumor location, differentiation grade, and pathological TNM stage were recorded according to Japanese classification of gastric carcinoma by JGCA
