T0 Gastric Cancer pT0 TNM Finding C61182 NCI Thesaurus Gastric cancer with no evidence of a primary tumor. (from AJCC 6th and 7th Eds.)
T1 Gastric Cancer pT1 TNM Finding v7 C89831 NCI Thesaurus Gastric cancer invading lamina propria, muscularis mucosae, or submucosa. (from AJCC 7th Ed.)
T1a Gastric Cancer pT1a TNM Finding v7 C89832 NCI Thesaurus Gastric cancer with tumor invading lamina propria or muscularis mucosae. (from AJCC 7th Ed.)
T1b Gastric Cancer pT1b TNM Finding v7 C89833 NCI Thesaurus Gastric cancer invading the submucosa. (from AJCC 7th Ed.)
T2 Gastric Cancer pT2 TNM Finding v7 C89834 NCI Thesaurus Gastric cancer with tumor invading the muscularis propria. A tumor may penetrate the muscularis propria with extension into the gastrocolic or gastrohepatic ligaments, or into the greater or lesser omentum, without perforation of the visceral peritoneum covering these structures. In this case, the tumor is classified T3. If there is perforation of the visceral peritoneum covering the gastric ligaments or the omentum, the tumor should be classified T4. (from AJCC 7th Ed.)
T3 Gastric Cancer pT3 TNM Finding v7 C89838 NCI Thesaurus Gastric cancer with tumor penetrating subserosal connective tissue without invasion of visceral peritoneum or adjacent structures. The adjacent structures of the stomach include the spleen, transverse colon, liver, diaphragm, pancreas, abdominal wall, adrenal gland, kidney, small intestine, and retroperitoneum. Intramural extension to the duodenum or esophagus is classified by the depth of the greatest invasion in any of these sites, including the stomach. (from AJCC 7th Ed.)
T4 Gastric Cancer pT4 TNM Finding v7 C89839 NCI Thesaurus Gastric cancer with tumor invading serosa (visceral peritoneum) or adjacent structures. The adjacent structures of the stomach include the spleen, transverse colon, liver, diaphragm, pancreas, abdominal wall, adrenal gland, kidney, small intestine, and retroperitoneum. Intramural extension to the duodenum or esophagus is classified by the depth of the greatest invasion in any of these sites, including the stomach. (from AJCC 7th Ed.)
T4a Gastric Cancer pT4a TNM Finding v7 C89840 NCI Thesaurus Gastric cancer with tumor invading serosa (visceral peritoneum). (from AJCC 7th Ed.)
T4b Gastric Cancer pT4b TNM Finding v7 C89841 NCI Thesaurus Gastric cancer with tumor invading adjacent structures. (from AJCC 7th Ed.)
TX Gastric Cancer pTX TNM Finding C61181 NCI Thesaurus Gastric cancer in which the primary tumor cannot be assessed. (from AJCC 6th and 7th Eds.)
Tis Gastric Cancer pTis TNM Finding C61183 NCI Thesaurus Gastric cancer in situ with cancer cells confined within the glandular basement membrane (intraepithelial) and without invasion into the lamina propria. (from AJCC 6th and 7th Eds.)
