This study investigated if the expressions of ZNF652 and androgen receptor (AR) in prostate cancer are associated with prostate specific antigen (PSA) defined relapse.
Our preliminary experience suggests that performing <sup>68</sup> Ga-PSMA PET/CT in patients with prostate cancer with rising PSA after treatment with curative intent can be clinically useful as it changes the treatment strategy in a significant proportion of patients.
In this randomised trial, we tested whether chemotherapy after surgery for high-risk prostate cancer decreases the risk of a rising prostate-specific antigen.
Epigenetic silencing of GSTM2 and MYCL2 comprise novel molecular markers to predict BCR after surgery for medium- and high-risk localized PCa undergoing surgical treatment and hypermethylation of these genes could be incorporated to the clinical and pathological factors defining the patient at higher risk of PSA failure after prostatectomy.
Among men with prostate specific antigen doubling time less than 9 months after the prostate specific antigen rise, salvage androgen deprivation therapy was statistically significantly associated with a decreased risk of all-cause and prostate cancer specific mortality in the prostatectomy cohort (HR 0.35, 95% CI 0.20-0.63 and HR 0.43, 95% CI 0.21-0.91) and in the radiotherapy cohort (HR 0.62, 95% CI 0.48-0.80 and HR 0.65, 95% CI 0.47-0.90, respectively).
When we evaluated these two tSNPs together based on the risk alleles (that is, rs6434568 C and rs16834898 A), we found that the combined genotypes with four risk alleles were associated with an increased risk of PCa compared with those carrying 0-3 risk alleles (1.53, 1.19-1.97), and this increased risk was more pronounced among subjects of≤70 years (1.80, 1.24-2.62), Gleason score≥7 (1.68, 1.28-2.22) and PSA level≥20 (1.64, 1.24-2.18).
Eight hundred and seventy-six biopsy-naive men with clinical suspicion of prostate cancer (prostate-specific antigen, <50 ng/mL; tumour stage, <T3) underwent pre-biopsy prostate bpMRI (T2-weighted and diffusion-weighted) followed by 10-core standard biopsies (all men) and MRI-transrectal ultrasound fusion targeted biopsies of bpMRI-suspicious lesions (suspicion score, ≥3).
In conclusion, loci associated with risk for prostate cancer, such as rs7920517 and rs10993994, might also be used to predict the recurrence of prostate-specific antigen in prostate cancer patients receiving radical prostatectomy.
Secondary objectives included safety, antitumour activity (Prostate Cancer Working Group 2 (PCWG2) criteria; 30% of prostate-specific antigen (PSA) decline at ≥week 12) and pharmacokinetic (PK) profile.
Increasing detectable pre-salvage radiotherapy prostate specific antigen (0.01 to 0.2, greater than 0.2 to 0.5 and greater than 0.5 ng/ml) predicted worse 10-year biochemical relapse-free survival (62%, 44% and 27%), freedom from salvage androgen deprivation therapy (77%, 66% and 49%), distant metastases-free survival (86%, 79% and 66%, each p <0.001) and prostate cancer specific survival (93%, 89% and 80%, respectively, p = 0.001).
In this study, we assess the nationwide and regional disparity in prostate-specific antigen (PSA) screening for prostate cancer between Black men and non-Hispanic Whites (NHWs).
We also enquired whether Q640X CTE-truncated androgen receptor (AR) has an impact on transcription of mRNA for PSMA and PSA in transfected androgen-sensitive prostate cancer LNCaP cells.
Our results provide further support that a PC-risk SNP rs2735839 near the KLK3 gene on chromosome 19q13 may be associated with aggressive and high-grade PC.
We recently reported an association between prostate cancer risk and polymorphisms in the prostate-specific antigen (PSA) and androgen receptor (AR) genes.
To determine the association among prostate cancer gene 3 (PCA3) score, Prostate Imaging Reporting and Data System (PI-RADS) grade and Gleason score, in a cohort of patients with elevated prostate-specific antigen (PSA), undergoing magnetic resonance imaging/ultrasonography fusion software-based targeted prostate biopsy (TBx) after a previous negative randomised 'standard' biopsy (SBx).
Of those diagnosed with prostate cancer 25 (68%) had prostate specific antigen 1.5 ng/ml or greater and all men with a Gleason score of 7 or greater had prostate specific antigen 1.5 ng/ml or greater.
Biochemical control, distant metastasis-free survival (DMFS), prostate cancer-specific survival (PCSS), and overall survival (OS) were compared between those who achieved a nadir PSA ≤0.5 ng/mL with those who did not via Kaplan-Meier analysis.
We evaluated associations between the 36 polymorphisms and prostate cancer survival, as well as other clinical parameters including age at diagnosis, prostate-specific antigen (PSA) at diagnosis, and Gleason score.
Genotype TG on 11q13 (rs7931342, T) could be related to an increased Gleason score, AG on HNF1B (rs4430796, A) could be associated with PSA increase, and TG on 17q24 (rs1859962, G) could be negatively associated with an increased BMI in Chinese men with PCa.
