For my link archive:
- [WayBack] Colorectal Cancer: Stages | Cancer.Net.
- TNM staging system – Wikipedia
- [Wayback] Pathology Outlines – Staging-carcinoma: Colon tumor – Pathologic TNM staging of colorectal carcinoma (AJCC 8th edition)
- [Wayback] The Radiology Assistant : Rectal Cancer MR staging (with lots of imagery describing the various parts of the stages)
- [Wayback] ColonSmall.pdf: American Joint Committee on Cancer: Colon and Rectum Cancer Staging
These explain the below stagings.
- cT3N1Mx:
- c: stage determined before treatment
- T3: tumor invades through the muscularis propria into the pericolorectal tissues
- N1: regional lymph node metastasis suspicious in 1-3 lymph nodes
- Mx: could not be evaluated for distant metastasis
- cT3bN1Mx:
- c: stage determined before treatment
- T3b: 1-5 mm extension beyond muscularis propria
- N1: regional lymph node metastasis suspicious in 1-3 lymph nodes
- Mx: could not be evaluated for distant metastasis
- cT3N1M0:
- c: stage determined before treatment
- T3: tumor invades through the muscularis propria into the pericolorectal tissues
- N1: regional lymph node metastasis suspicious in 1-3 lymph nodes
- M0: no distant metastasis
- cT3bN1M0:
- c: stage determined before treatment
- T3b: 1-5 mm extension beyond muscularis propria
- N1: regional lymph node metastasis suspicious in 1-3 lymph nodes
- M0: no distant metastasis
- cT3bN1:
- c: stage determined before treatment
- T3b: 1-5 mm extension beyond muscularis propria
- N1: regional lymph node metastasis suspicious in 1-3 lymph nodes
- ypT2N1a:
- yp: stage determined after chemotherapy (y) and histopathologic (p), in this case also after surgeries of both tumor and metastases
- T2: size of tumor
- N1a: regional lymph node metastasis present in 1 lymph node
- No M means no metastasis detectable
