AbstractProstate cancer is one of the most common and a serious malignancy of males and it is well reported that estrogen plays a pivotal role in prostate carcinogenesis. Catechol-O - methyltransferase (COMT) catalyzes the inactivation of estrogens. Several studies have investigated the association of COMT gene Val158Metpolymorphism with prostate cancer, but results were inconsistent and inconclusive. Hence, to assess this association, we performed a meta-analysis of all published case-control studies. Pubmed, Springer link, Google Scholar, Elsevier and Springer link databases were searched for case-control studies. Odds ratios (ORs) with 95% confidence intervals (CIs) was used as association measure. Statistical analysis was performed with the software program MIX and MetaAnalyst. In the current meta-analysis, 11 case control studies with 3381 prostate cancer cases and 3,276 healthy controls were considered. The results indicated no significant association between COMT Val158Met polymorphism and prostate cancer risk using allele contrast, co-dominant and homozygote models (allele contrast: OR= 0.92; 95% CI 0.85 to 0.98=; p= 0.02; co-dominant: OR=0.81; 95% CI= 0.85 to1.07; p= 0.46; homozygote: OR= 0.81; 95% CI= 0.70 to 0.95, p= 0.008), but showed significant association with dominant and recessive models (dominant: OR 1.18=; 95% CI= 1.03 to1.34; p= 0.01; recessive: OR= 1.54; 95% CI= 1.1 to 2.07; p = 0.003). In subgroup analysis meta-analysis using recessive genetic model showed significant association between COMT Val 158Met polymorphism and prostate cancer risk in both Asian and Caucasian populations. In conclusion, results of present meta-analysis supports that the COMT Val158Met polymorphism is risk factor for prostate cancer.

Background Urological cancers occur worldwide. Many factors, among which the catechol-O-methyltransferase (COMT) Val158Met polymorphism, are said to be associated with the cancer risk. We conducted a meta-analysis to investigate the association between urological cancer susceptibility and COMT Val158Met in different genetic models. Methods This study was based on material obtained from the PubMed, HuGENet and Embase databases. Four models including dominant (AA + AG vs. GG), recessive (AA vs. AG + GG), codominant (AA vs. AG, AA vs. GG) and per-allele analysis (A vs. G) were applied. Odds ratios (OR) and the corresponding 95% confidence intervals (CI) were used to evaluate the power of the associations. Results Fourteen eligible studies comprising 3,285 cases and 3,594 controls were included. Although we could not detect a positive function of the COMT Val158Met polymorphism in urological cancers, the polymorphism might be significantly associated with bladder cancer risk (dominant model [AA + AG vs. GG]: OR = 0.736, 95% CI = 0.586-0.925, I2 = 0.00%; recessive model [AA vs. AG + GG]: OR = 0.822, 95%CI = 0.653-1.035, I2 = 6.30%; codominant model [AA vs. AG]: OR = 0.908, 95% CI = 0.710-1.161, I2 = 0.00%; codominant model [AA vs. GG]: OR = 0.693, 95% CI = 0.524-0.917, I2 = 30.20%; allele analysis [A vs. G]: OR = 0.826, 95%CI = 0.717-0.951, I2 = 30.20%). The same significant associations were not found for kidney cancer and prostate cancer risk in different ethnicities. There also seemed to be no distinct effect of the polymorphism on benign prostatic hyperplasia. Conclusions We suggest that bladder cancer but not prostate cancer and kidney cancer could be significantly associated with the Val158Met polymorphism. Interaction of COMT genetic and related environmental factors for urological cancers should not be ignored in future.

Abstract While being in a committed relationship is associated with a better prostate cancer prognosis, little is known about how marital status relates to its incidence. Social support provided by marriage/relationship could promote a healthy lifestyle and an increased healthcare seeking behavior.We investigated the association between marital status and prostate cancer risk using data from the PRACTICAL Consortium. Pooled analyses were conducted combining 12 case-control studies based on histologically-confirmed incident prostate cancers and controls with information on marital status prior to diagnosis/interview. Marital status was categorized as married/partner, separated/divorced, single, or widowed. Tumours with Gleason scores ≥8 defined high-grade cancers, and low-grade otherwise. NCI-SEER’s summary stages (local, regional, distant) indicated the extent of the cancer. Logistic regression was used to derive odds ratios (ORs) and 95% confidence intervals (CI) for the association between marital status and prostate cancer risk, adjusting for potential confounders. Overall, 14,760 cases and 12,019 controls contributed to analyses. Compared to men who were married/with a partner, widowed men had an OR of 1.19 (95%CI 1.03-1.35) of prostate cancer, with little difference between low- and high-grade tumours. Risk estimates among widowers were 1.14 (95%CI 0.97-1.34) for local, 1.53 (95%CI 1.22-1.92) for regional, and 1.56 (95%CI 1.05-2.32) for distant stage tumours. Single men had elevated risks of high-grade cancers. Our findings highlight elevated risks of incident prostate cancer among widowers, more often characterized by tumours that had spread beyond the prostate at the time of diagnosis. Social support interventions and closer medical follow-up in this sub-population are warranted.
