Cells with a high NC ratio (small cell carcinoma).
Nucleus-to-cytoplasm ratio, also nuclear-cytoplasmic ratio, is the relative size of the nucleus to the cytoplasm. It is commonly abbreviated NC ratio.
High NC ratio is strong predictor of malignancy.[1] Like very rule, there are exceptions.
High NC ratio in normal cells
- Lymphocytes.
Low NC ratio in cancer
- Fibrolamellar hepatocellular carcinoma.
- Acinic cell carcinoma.
- Many others.
High NC ratio in cancer
The classic malignant high NC ratio cell is small cell carcinoma, which is in the large small round cell tumour group.
- Many other tumours - see A long differential diagnosis of small blue cell tumours.
Atypical cells with a normal NC ratio
- Radiation changes - clinical history is important!
- Many tumours.
