PDQ® Adult Treatment Editorial Board. Esophageal Cancer Treatment (PDQ®) – Health Professional Version. National Cancer Institute — reprints the AJCC 8th-edition pTNM tables for squamous cell carcinoma (with grade and tumour location) and adenocarcinoma (with grade). Where a lower-third T3 N0 SCC has grade GX, the table matches both "lower, any grade → IIA" and "GX, any location → IIB"; this tool applies the location-specific row (IIA).
