Thyroid transcription factor-1, abbreviated TTF-1 is a transcription factor seen in lung and thyroid.[1]
Positive staining
- Nuclear staining.
Normal tissues
Tumours
Positive staining
- Lung adenocarcinoma.[2]
- Small cell carcinoma of the lung ~ 91% positive (157 +ve of 173[3]).
- Adenocarcinoma of the lung.
- Thyroid carcinoma.
- Hepatocellular carcinoma (cytoplasmic staining, nuclei negative).[4]
- Spindle cell oncocytoma / Pituicytoma / Granular cell tumor of the pituitary. [5]
- Subependymal giant cell astrocytoma [6]
Negative staining
- Squamous cell carcinoma of the lung.
- SMARCA4-deficient non-small cell carcinoma of the lung - typically ~ 5% of lung adenocarcinoma is TTF-1 negative.
