TNM v1.4 changes:

  • Oral Cavity schemas and Larynx Glottic: Path Stage Group notes regarding combinations only found in SEER*RSA were corrected. Stage Group IVA should have referenced Tis in addition to T0.
  • NasoPharynx: Path Stage Group notes regarding combinations only found in SEER*RSA were corrected. Stage Group IV is only in SEER*RSA; Stage Group II and III Tis combinations are only SEER*RSA.
  • Corpus Carcinoma: Clin N and Path N: N1 definition modified to replace text for FIGO IIIC with 'Statement of FIGO IIIC only' because it was confusing to have metastasis of para-aortic lymph nodes in both N1 and N2.
  • Rectum: The combined T table was replaced with the table used by Colon. The Colon table does NOT generate an error when both Clin T and Path T are pTis and Behavior = 3.
