NCIt synonyms : Stage IB Esophageal Cancer;
NCIt definition : Stage IB includes: For squamous cell carcinoma: (T1, N0, M0, G2-3, Tumor location:
Any); (T2-3, N0, M0, G1, GX, Tumor location: Lower, X). T1: Tumor invades lamina propria,
muscularis mucosae, or submucosa. T2: Tumor invades muscularis propria. T3: Tumor
invades adventitia. N0: No regional lymph node metastasis. M0: No distant metastasis.
G1: Well differentiated. GX: Grade cannot be assessed-stage grouping as G1. G2: Moderately
differentiated. G3: Poorly differentiated. Tumor location: Location of the primary
cancer site is defined by the position of the upper (proximal) edge of the tumor in
the esophagus. For adenocarcinoma: (T1, N0, M0, G3); (T2, N0, M0, G1-2, GX). T1: Tumor
invades lamina propria, muscularis mucosae, or submucosa. T2: Tumor invades muscularis
propria. N0: No regional lymph node metastasis. M0: No distant metastasis. G1: Well
