Observational analysis highlights PSMA and CK positivity in circulating tumor cells of prostate cancer patients, suggesting diagnostic implications.
PSMA positivity was observed to be highest in LNCaP with 88% above the level of 200 and CK positivity of 100% above the level of 50. The cells of both PC3 and RWPE-1 (negative for PSMA) showed 0.9% positivity above 200 for PSMA and 100% CK positivity above 50 for CK.
