Chromogranin A staining as a biomarker for prostate adenocarcinoma
As reported in The Prostate, chromogranin A (CgA) staining, an indicator of neuroendocrine differentiation, is associated with decreased biochemical control, clinical failure, increased distant metastases, and decreased cause-specific survival in patients with prostate adenocarcinoma and a GS ≥ 7 (n=285). The median follow-up was 6.5 y. CgA staining was present in 31% of specimens. The 10-y distant metastases rate in specimens with <1% and >1% CgA staining was 8% and 48%, respectively. The 10-y cause-specific survival in specimens with <1% and >1% CgA staining was 95% vs. 76%, respectively.
High expression of MUC1 + HER3 is associated with favorable outcome in bladder cancer patients
As reported in BJU International, elevated co-expression of MUC1 + HER3 was associated with improved survival in patients with bladder cancer. MUC1 alone, or elevated MUC1 + non-elevated HER3, had no prognostic value. Moreover, MUC1 was not predictive of survival, tumor stage, or tumor grade.
3-month PSA is a predictor of BCR-free survival after radical prostatectomy
As reported in the International Journal of Clinical Oncology, the 5-year biochemical recurrence (BCR)-free survival rate is significantly higher in patients with a 3-month PSA level < 0.010 ng/ml compared to patients with a 3-month PSA level between 0.010 and 100 ng/ml (92.6% vs. 57.4%). Amongst 174 men who underwent radical prostatectomy for clinically localized prostate cancer, 18.4% had a BCR and the median time to BCR was 16 months.
