Skewing Towards Neuroendocrine Phenotype in High Grade or High Stage Androgen-Responsive Primary Prostate Cancer
(2005) In European Urology 48(2). p.215-223- Abstract
- Objective:
The prognostic influence of neuroendocrine (NE) differentiation in prostate cancer patients is not yet properly established. In a series of primary hormone-naive prostate cancers from a patient population that underwent radical prostatectomy, we wanted to determine the relationship between NE phenotype expression and Gleason sum, disease stage, and serum PSA concentration.
Methods:
Chromogranin A (CgA) expression was scored and compared in 105 consecutive primary prostate cancers with their homologous preoperative tumor prostate biopsies.
Results:
High grade or high stage prostate cancers expressed a significantly higher CgA score than low grade or... (More) - Objective:
The prognostic influence of neuroendocrine (NE) differentiation in prostate cancer patients is not yet properly established. In a series of primary hormone-naive prostate cancers from a patient population that underwent radical prostatectomy, we wanted to determine the relationship between NE phenotype expression and Gleason sum, disease stage, and serum PSA concentration.
Methods:
Chromogranin A (CgA) expression was scored and compared in 105 consecutive primary prostate cancers with their homologous preoperative tumor prostate biopsies.
Results:
High grade or high stage prostate cancers expressed a significantly higher CgA score than low grade or localized diseases (p < 0.005). Both the CgA score of the surgical specimens and the PSA level in the serum increased linearly (p = 0.001). In the samples of many corresponding tumor biopsies no significant CgA staining was found.
Conclusion:
NE differentiation in primary untreated prostate cancer is closely associated with the major prognostic parameters of survival. This association cannot be shown by evaluating the CgA staining in tumor biopsies. (Less)
