Tumour regression can occur (1) sporadically, or (2) as a consequence of treatment (treatment response).
Sporadic tumour regression
Well-known:
May occur in:
Note:
Microscopic
Features:
- +/-Fibrosis.
- +/-Mucin.
- +/-Inflammation.
- +/-Histiocytes.
Note:
- There are specific criteria for malignant melanoma.
Grading of tumour regression
Colorectal carcinoma
Main article: Colorectal carcinoma
There is a three tiered regression grading system by Ryan et al. for colorectal cancer.[4]
Esophageal carcinoma
- The three tier system from Ryan et al. for colorectal cancer has been applied to esophageal carcinomas.[5]
Ovarian carcinoma
Main article: Ovarian carcinoma
This has been examined by McCluggage et al.[6]
