Neuroendocrine staining poor prognosticator

Neuroendocrine (NE) staining without NE morphology

The tumour's morphology is NOT in keeping with small cell carcinoma (the tumour cells have too much cytoplasm) and NOT in keeping with large cell neuroendocrine carcinoma (the tumour cells have nucleoli occasionally and eosinophilic cytoplasm).

The distinction between (A) carcinoma and (B) carcinoma with a neuroendocrine component is dependent on: (1) morphology and (2) neuroendocrine (NE) staining. This case has NE staining; however, it does NOT have a typical NE morphology. As such, the case does NOT have a definite neuroendocrine component.

It should be noted that NE marker positivity is predictive of hormone refractive disease.[1] Androgen receptor testing in this context has been described as being an additional useful test;[2] however, testing is not available in house.
