Overview
According to the American Joint Committee on Cancer, there are 4 stages of stomach cancer based on the tumor spread.
Staging
The American Joint Committee on Cancer has designated staging by TNM classification to define gastric cancer
Definitions of TNM
Stage | Description |
---|---|
TX | Primary tumor cannot be assessed |
Tis | Carcinoma in situ: intraepithelial tumor without invasion of the lamina propria |
T0 | No evidence of primary tumor |
T1 | Tumor invades lamina propria, muscularis mucosae, or submucosa
T1a: Tumor invades lamina propria or muscularis mucosae |
T2 | Tumor invades muscularis propria |
T3 | Tumor penetrates subserosal connective tissue without invasion of visceral peritoneum or adjacent structures |
T4 | T4: Tumor invades serosa (visceral peritoneum) or adjacent structures
T4a: Tumor invades serosa (visceral peritoneum) T4b: Tumor invades adjacent structures |
Stage | Description |
---|---|
NX | Regional lymph node cannot be assessed |
N0 | No regional lymph node metastasis |
N1 | Metastasis in 1-2 regional lymph nodes |
N2 | Metastasis in 3-6 regional lymph nodes |
N3 | Metastasis in seven or more regional lymph nodes
N3a: Metastasis in 7-15 regional lymph nodes N3b: Metastasis in 16 or more regional lymph nodes |
