NCI Definition: A neuroendocrine carcinoma of the prostate gland with unfavorable prognosis, composed of small cells containing neurosecretory granules. Approximately half of the cases show a mixture of small cells and adenocarcinoma cells. [1]

Prostate small cell carcinomas most frequently harbor alterations in RB1, TP53, TMPRSS2, ERG, and PTEN [2].

Most Commonly Altered Genes in Prostate Small Cell Carcinoma

TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, RB1 Loss, and TMPRSS2-ERG Fusion are the most common alterations in prostate small cell carcinoma [2].
