We examined whether the DNA-PK activity of peripheral blood lymphocytes (PBLs) was related to biochemical (prostate-specific antigen: PSA) relapse and radiation toxicity in prostate cancer patients who have received radiotherapy.
Group II had a lower risk of PSA progression [hazard ratio (HR) = 0.43, 95% confidence interval (CI) 0.27,0.69, p = 0.001], metastasis development (HR = 0.51, 95% CI 0.27,0.97, p = 0.040) and overall mortality (HR = 0.49, 95% CI 0.26,0.92, p = 0.027), but not of PCa-specific death (HR = 0.45, 95% CI 0.19,1.08, p = 0.074).
An observational population-based Swedish study from 1996 to 2010 of men at high risk of disseminated prostate cancer (prostate-specific antigen [PSA] >50) initially treated by radical therapy (radiation therapy [n=630] or radical prostatectomy [n=120]) or androgen deprivation therapy (n=17 602), and followed for up to 15 yr.
All men had intermediate- (T1-2, Gleason score 7 and/or prostate-specific antigen [PSA] 10-20 ng/mL) or high-risk (T3 and/or Gleason score 8-10 and/or PSA 20-50 ng/mL) localized PCa diagnosed between 1 January 2006 and 31 December 2014.
The results suggest that some VDR gene polymorphisms in Korean men might not only be associated with prostate cancer risk but also significantly related to prostate cancer-related risk factors such as PSA level, tumor stage, and Gleason score.
ERG, SLC45A3 and PTEN immunostaining and their association with pathological features and PSA progression-free survival were analyzed in 220 PrCa (PSMAR-Biobank, Barcelona, Spain).
We concluded that the hypoechoic lesions in TRUS could improve the predictive accuracy for diagnosing prostate cancer and present different predictive efficacy in the respective PSA intervals.
These findings confirm an increased cancer risk associated with the G84E mutation in the Finnish population, particularly for early-onset prostate cancer and cases with substantially elevated PSA.
In both groups there was a curative intention to treat localized high-risk prostate cancer (one or more of Gleason score 8-10, PSA 20-50 or stage T3), diagnosed between 1995-2010, follow-up at the end of 2014.
Between 1995 and 2001, 206 men with unfavorable-risk PC were randomized to receive radiation therapy alone or in combination with 6 months of androgen deprivation therapy (ADT); 108 men experienced PSA failure and formed the study cohort.
Recently, gene fusions involving the prostate-specific gene transmembrane protease, serine 2 (TMPRSS2) and members of the erythroblastosis virus E26 transforming sequence (ETS) family of transcription factors were identified in most of PSA-screened prostate cancers.
We identified 6.509 patients with prostate cancer who had received hormonal therapy with a post-hormonal therapy PSA ≥2ng/mL, 363 of whom had non-metastatic, castrate-resistant prostate cancer.
Analyses were restricted to 2007 patients who harbored low-risk PCa at ≥10-cores initial biopsy according to D'Amico classification (PSA <10.0 ng/ml, Gleason score <7 and clinical stage ≤T2a).
Distributions and characteristics of initial PSA and PSA velocity in Chinese men aged 50 years and younger without prostate cancer: a multi-center study.
The present study aimed to investigate the diagnostic efficacy and the regional location of prostate cancer (PCa) as well as the accuracy of assessment between trans-perineal template-guided mapping biopsy (TTMB) and freehand trans-perineal biopsy (FTPB) for men with PSA < 20 ng/ml.
We therefore studied VDR gene polymorphisms, as detected by Apal and Taql restriction fragments, in multiethnic Brazilian men (165 patients and 200 controls) for association with prostate cancer risk and parameters of disease severity (serum PSA, Gleason score and tumor stage).No statistical correlations were found.
