A member asked:
Are p63 and ttf1 used to distinguish small cell lung cancer from non small cell lung cancer? or are they used for more specific distinctions?
A doctor has provided 1 answer
Yes: P63 is positive in lung squamous cell cancers usually while ttf1 (thyroid transcription factor) is positive frequently in lung adenocarcinomas. Both should be negative in small cell lung cancers usually.
