Abstract
It has been a long-standing debate in the research and medical societies whether alcohol consumption is linked to the risk of prostate cancer (PCa). Many comprehensive studies from different geographical areas and nationalities have shown that moderate and heavy drinking is positively correlated with the development of PCa. Nevertheless, some observations could not confirm that such a correlation exists; some even suggest that wine consumption could prevent or slow prostate tumor growth. Here, we have rigorously analyzed the evidence both for and against the role of alcohol in PCa development. We found that many of the epidemiological studies did not consider other, potentially critical, factors, including diet (especially, low intake of fish, vegetables and linoleic acid, and excessive use of red meat), smoking, family history of PCa, low physical activity, history of high sexual activities especially with early age of first intercourse, and sexually transmitted infections. In addition, discrepancies between observations come from selectivity criteria for control groups, questionnaires about the type and dosage of alcohol, and misreported alcohol consumption. The lifetime history of alcohol consumption is critical given that a prostate tumor is typically slow-growing; however, many epidemiological observations that show no association monitored only current or relatively recent drinking status. Nevertheless, the overall conclusion is that high alcohol intake, especially binge drinking, is associated with increased risk for PCa, and this effect is not limited to any type of beverage. Alcohol consumption is also directly linked to PCa lethality as it may accelerate the growth of prostate tumors and significantly shorten the time for the progression to metastatic PCa. Thus, we recommend immediately quitting alcohol for patients diagnosed with PCa. We discuss the features of alcohol metabolism in the prostate tissue and the damaging effect of ethanol metabolites on intracellular organization and trafficking. In addition, we review the impact of alcohol consumption on prostate-specific antigen level and the risk for benign prostatic hyperplasia. Lastly, we highlight the known mechanisms of alcohol interference in prostate carcinogenesis and the possible side effects of alcohol during androgen deprivation therapy.

Alcohol Consumption and the Risk of Prostate Cancer: A Dose-Response Meta-Analysis. Nutrients 2020; 12:nu12082188. [PMID: 32717903 PMCID: PMC7468718 DOI: 10.3390/nu12082188] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2020] [Revised: 07/17/2020] [Accepted: 07/21/2020] [Indexed: 01/06/2023] Open
Abstract
Alcohol is widely consumed and is known as a major risk factor for several types of cancers. Yet, it is unclear whether alcohol consumption is associated with the risk of prostate cancer (PCa) or not. We conducted linear and non-linear dose–response meta-analyses of cohort studies on alcohol consumption and PCa risk by types of alcohol (total, wine, beer, and liquor) and PCa (non-aggressive and aggressive). Pubmed and Embase were searched through April 2020 to identify relevant studies. Summary relative risk (RR) and 95% confidence interval (CI) were estimated using a random-effects model. For non-aggressive PCa, by alcohol type, the risk increased linearly with liquor (RR per 14 g/day intake (alcohol content in standard drink) being 1.04 (95% CI = 1.02–1.06, I2 = 0%, three studies) and non-linearly with beer (Pnon-linearity = 0.045, four studies), with increased risk observed in the lower range (RR = 1.03, 95% CI = 1.01–1.05; 14 g/day), with 1.05 (95% CI = 1.01–1.08) at 28 g/day. Wine was not significantly associated with the risk of non-aggressive PCa. For aggressive PCa, a non-linear relationship of diverse shapes was indicated for all types of alcohol in the sensitivity analysis. Compared to non-drinking, a significant positive association was more apparent at lower dose for liquor (RR = 1.12, 95% CI = 1.04–1.20 at 14 g/day; RR = 1.16, 95% CI = 1.03–1.31 at 28 g/day; Pnon-linearity = 0.005, three studies) but at higher doses for wine (RR = 1.02, 95% CI = 0.90–1.16 at 28 g/day, RR = 1.35, 95% CI = 1.08–1.67 at 56 g/day; Pnon-linearity = 0.01, four studies). In contrast, decreased risks were indicated at lower doses of beer (RR = 0.85, 95% CI = 0.79–0.92 at 14 g/day; RR = 0.79, 95% CI = 0.70–0.90 at 28 g/day, Pnon-linearity < 0.001, four studies). Total alcohol consumption was not associated with both types of PCa. In this study, we found heterogeneous associations between alcohol intake and PCa by types of alcohol and PCa.

Abstract
PURPOSE It is unknown whether alcohol intake is associated with the risk of lethal (metastatic or fatal) prostate cancer. We examine (1) whether alcohol intake among men at risk of prostate cancer is associated with diagnosis of lethal prostate cancer and (2) whether intake among men with nonmetastatic prostate cancer is associated with metastasis or death. METHODS This prospective cohort study uses the Health Professionals Follow-Up Study (1986 to 2012). Our analysis of alcohol intake among men at risk of prostate cancer included 47,568 cancer-free men. Our analysis of alcohol intake among men with prostate cancer was restricted to 5,182 men diagnosed with nonmetastatic prostate cancer during follow-up. We examine the association of total alcohol, red and white wine, beer, and liquor with lethal prostate cancer and death. Multivariate Cox proportional hazards regression estimated hazard ratios (HRs) and 95% CIs. RESULTS Alcohol drinkers had a lower risk of lethal prostate cancer (any v none: HR, 0.84 [95% CI, 0.71 to 0.99]) without a dose-response relationship. Total alcohol intake among patients with prostate cancer was not associated with progression to lethal prostate cancer (any v none: HR, 0.99 [95% CI, 0.57 to 1.72]), whereas moderate red wine intake was associated with a lower risk (any v none: HR, 0.50 [95% CI, 0.29 to 0.86]; P trend = .05). Compared with none, 15 to 30 g/d of total alcohol after prostate cancer diagnosis was associated with a lower risk of death (HR, 0.71 [95% CI, 0.50 to 1.00]), as was red wine (any v none: HR, 0.74 [95% CI, 0.57 to 0.97]; P trend = .007). CONCLUSION Cancer-free men who consumed alcohol had a slightly lower risk of lethal prostate cancer compared with abstainers. Among men with prostate cancer, red wine was associated with a lower risk of progression to lethal disease. These observed associations merit additional study but provide assurance that moderate alcohol consumption is safe for patients with prostate cancer.

Abstract
Objective To investigate the impact of moderate wine consumption on the risk of prostate cancer (PCa). We focused on the differential effect of moderate consumption of red versus white wine. Design This study was a meta-analysis that includes data from case–control and cohort studies. Materials and methods A systematic search of Web of Science, Medline/PubMed, and Cochrane library was performed on December 1, 2017. Studies were deemed eligible if they assessed the risk of PCa due to red, white, or any wine using multivariable logistic regression analysis. We performed a formal meta-analysis for the risk of PCa according to moderate wine and wine type consumption (white or red). Heterogeneity between studies was assessed using Cochrane’s Q test and I2 statistics. Publication bias was assessed using Egger’s regression test. Results A total of 930 abstracts and titles were initially identified. After removal of duplicates, reviews, and conference abstracts, 83 full-text original articles were screened. Seventeen studies (611,169 subjects) were included for final evaluation and fulfilled the inclusion criteria. In the case of moderate wine consumption: the pooled risk ratio (RR) for the risk of PCa was 0.98 (95% CI 0.92–1.05, p=0.57) in the multivariable analysis. Moderate white wine consumption increased the risk of PCa with a pooled RR of 1.26 (95% CI 1.10–1.43, p=0.001) in the multi-variable analysis. Meanwhile, moderate red wine consumption had a protective role reducing the risk by 12% (RR 0.88, 95% CI 0.78–0.999, p=0.047) in the multivariable analysis that comprised 222,447 subjects. Conclusions In this meta-analysis, moderate wine consumption did not impact the risk of PCa. Interestingly, regarding the type of wine, moderate consumption of white wine increased the risk of PCa, whereas moderate consumption of red wine had a protective effect. Further analyses are needed to assess the differential molecular effect of white and red wine conferring their impact on PCa risk.

Abstract
PURPOSE Alcohol intake may be associated with cancer risk, but epidemiologic evidence for prostate cancer is inconsistent. We aimed to prospectively investigate the association between midlife alcohol intake and drinking patterns with future prostate cancer risk and mortality in a population-based cohort of Finnish twins. METHODS Data were drawn from the Older Finnish Twin Cohort and included 11,372 twins followed from 1981 to 2012. Alcohol consumption was assessed by questionnaires administered at two time points over follow-up. Over the study period, 601 incident cases of prostate cancer and 110 deaths from prostate cancer occurred. Cox regression was used to evaluate associations between weekly alcohol intake and binge drinking patterns with prostate cancer risk and prostate cancer-specific mortality. Within-pair co-twin analyses were performed to control for potential confounding by shared genetic and early environmental factors. RESULTS Compared to light drinkers (≤3 drinks/week; non-abstainers), heavy drinkers (>14 drinks/week) were at a 1.46-fold higher risk (HR 1.46; 95 % CI 1.12, 1.91) of prostate cancer, adjusting for important confounders. Among current drinkers, binge drinkers were at a significantly increased risk of prostate cancer (HR 1.28; 95 % CI 1.06, 1.55) compared to non-binge drinkers. Abstainers were at a 1.90-fold higher risk (HR 1.90; 95 % CI 1.04, 3.47) of prostate cancer-specific mortality compared to light drinkers, but no other significant associations for mortality were found. Co-twin analyses suggested that alcohol consumption may be associated with prostate cancer risk independent of early environmental and genetic factors. CONCLUSION Heavy regular alcohol consumption and binge drinking patterns may be associated with increased prostate cancer risk, while abstinence may be associated with increased risk of prostate cancer-specific mortality compared to light alcohol consumption.

Abstract
Background Deletions of the glutathione S-transferase genes M1 and T1 (GSTM1 and GSTT1) have been studied as potential risk factors for prostate cancer. Conflicting results have been obtained. Moreover, most such studies could not discriminate heterozygous from homozygous carriers of the non-deleted alleles. Objective We investigated whether copy number variation (CNV) of the GSTM1 and/or GSTT1 genes contribute to the risk of prostate cancer in the Caribbean population of African descent of Guadeloupe. Methods In a population-based case-control study, we compared 629 prostate cancer patients and 622 control subjects. Logistic regression was used to estimate adjusted odds ratios (OR) and 95% confidence intervals (CI). Exact copy numbers of GSTM1 and GSTT1 were determined by real-time PCR. Results A higher copy number of GSTM1 was marginally associated with prostate cancer risk. Men with 2 and 3 or more GSTT1 genes were at higher risk of prostate cancer (OR: 1.55, 95% CI: 1.11–2.16 and OR: 4.89, 95% CI: 1.71–13.99, respectively; Ptrend<0.001). Men with 3, 4 and 5 or more copies of both GSTM1 and GSTT1 genes were at higher risk of prostate cancer (OR: 2.18, 95% CI: 1.21–3.91, OR: 3.24, 95% CI: 1.63–6.46, and OR: 5.77, 95% CI: 1.40–23.84, respectively; Ptrend<0.001). Conclusions Copy number of GSTT1 and combined GSTM1/GSTT1 appear to be associated with prostate cancer risk in our population study with gene dose relationship. Our results support the hypothesis that variations in copy number of GSTT1 modulate the risk of prostate cancer.

Abstract
PURPOSE Alcohol consumption may be a modifiable risk factor for prostate cancer, but previous results have been inconsistent and limited by a lack of data on lifetime exposure and specific beverages. Furthermore, the effect of tumor stage and severity of disease on the association between alcohol and prostate cancer risk has not been fully investigated. METHODS We examined the relation between both current and lifetime alcohol intake and prostate cancer risk in a population-based case-control study in Alberta, Canada with 947 cases with stage T2 and higher prostate cancer diagnosed between 1997 and 2000 and frequency matched to 1,039 controls, identified through random digit dialing. Cases were classified on cancer stage and severity into 619 non-aggressive (Stage II and Gleason score <8) and 328 aggressive cases (Stage III/IV or Gleason score ≥8). In-person interviews were completed on current and lifetime history of alcohol consumption and all other prostate cancer risk factors. RESULTS Current alcohol intake did not increase prostate cancer risk but lifetime intake increased risk for both non-aggressive and aggressive cases, with an odds ratio of 1.78 (95 % CI 1.19-2.66) and 2.00 (95 % CI 1.19-3.36), respectively, for the highest intake quartile compared to non-drinkers with evidence for a linear trend. Associations with alcohol intake remained after exclusion of non-drinkers for non-aggressive prostate cancer cases. Only lifetime beer intake was significantly associated with increased risk, however, intakes of liquor and wine by participants were low. CONCLUSIONS Results support the evidence for an increased risk of prostate cancer from lifetime alcohol consumption.

Abstract
Prostate cancer is the second most diagnosed cancer in men next to skin cancer in the developed world. Risk of disease varies most prominently with age, ethnicity, family history, and diet. Genetic polymorphism of some genes has been implicated in increasing the risk. The XPD (Xeroderma pigmentosum group D) gene codes for a DNA helicase involved in transcription and nucleotide excision repair. The aim of this study is to evaluate the effect of XPD 751 Lys/Gln polymorphism on risk of prostate cancer on north Indian patients. Blood sample from 150 prostate cancer patients, 150 from Prostate Hyper Plasia and equal number of samples from healthy control groups was collected from North India. The polymerase chain reaction and restrictive fragment length polymorphism techniques were implemented. Statistically non-significant increase risk of prostate cancer was observed with patients having Gln/Gln genotype (OR 1.62, 95% CI).

Abstract
Although there is evidence from studies of prostate cancer cell lines and rodent models that several supplements may have antiinflammatory, antioxidant, or other anticancer properties, few epidemiologic studies have examined the association between nonvitamin, nonmineral, "specialty" supplement use and prostate cancer risk. Participants, 50-76 yr, were 35,239 male members of the VITamins and Lifestyle (VITAL) cohort who were residents of western Washington state, and who completed an extensive baseline questionnaire in 2000-2002. Participants responded about their frequency (days/wk) and duration (yr) of specialty supplement uses. 1,602 incident invasive prostate cancers were obtained from the Surveillance, Epidemiology, and End Results registry. Multivariate-adjusted hazards ratios (HR) and 95% confidence intervals (95% CI) were estimated by Cox proportional hazards models. Any use of grapeseed supplements was associated with a 41% (HR 0.59, 95% CI: 0.40-0.86) reduced risk of total prostate cancer. There were no associations for use of chondroitin, coenzyme Q10, fish oil, garlic, ginkgo biloba, ginseng, glucosamine, or saw palmetto. Grapeseed may be a potential chemopreventive agent; however, as current evidence is limited, it should not yet be promoted for prevention of prostate cancer.

Abstract
Prostate growth is dependent on circulating androgens which can be influenced by hepatic function. Liver disease has been suggested to influence prostate cancer (CaP) incidence. However, the effect of hepatic function on CaP outcomes has not been investigated. A total of 1,181 patients who underwent radical prostatectomy (RP) between 1988 and 2008 at four Veterans Affairs hospitals that comprise the Shared Equal Access Regional Cancer Hospital (SEARCH) database and had available liver function test (LFT) data were included in the study. Independent associations of LFTs with unfavorable pathological features and biochemical recurrence were determined using logistic and Cox regression analyses. Serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT) levels were elevated in 8.2% and 4.4% of patients, respectively. After controlling for CaP features, logistic regression revealed a significant association between SGOT levels and pathological Gleason sum ≥7(4+3) cancer (odds ratio=2.12; 95% confidence interval=1.11-4.05; p=0.02). Mild hepatic dysfunction was significantly associated with adverse CaP grade but was not significantly associated with other adverse pathological features or biochemical recurrence in a cohort of men undergoing R. The effect of moderate to severe liver disease on disease outcomes in CaP patients managed non-surgically remains to be investigated.

Abstract
BACKGROUND Current research is inconclusive regarding the relation between alcohol consumption and prostate cancer risk. In this study, the authors examined the associations of total alcohol, type of alcoholic beverage, and drinking pattern with the risk of total, low-grade, and high-grade prostate cancer. METHODS Data for this study came from the 2129 participants in the Prostate Cancer Prevention Trial (PCPT) who had cancer detected during the 7-year trial and 8791 men who were determined by biopsy to be free of cancer at the trial end. Poisson regression was used to calculate relative risks (RRs) and 95% confidence intervals (95% CIs) for associations of alcohol intake with prostate cancer risk. RESULTS Associations of drinking with high-grade disease did not differ by treatment arm. In combined arms, heavy alcohol consumption (> or =50 g of alcohol daily) and regular heavy drinking (> or =4 drinks daily on > or =5 days per week) were associated with increased risks of high-grade prostate cancer (RR, 2.01 [95% CI, 1.33-3.05] and 2.17 [95% CI, 1.42-3.30], respectively); less heavy drinking was not associated with risk. Associations of drinking with low-grade cancer differed by treatment arm. In the placebo arm, there was no association of drinking with risk of low-grade cancer. In the finasteride arm, drinking > or =50 g of alcohol daily was associated with an increased risk of low-grade disease (RR, 1.89; 95% CI, 1.39-2.56); this finding was because of a 43% reduction in the risk of low-grade cancer attributable to finasteride treatment in men who drank <50 g of alcohol daily and the lack of an effect of finasteride in men who drank > or =50 g of alcohol daily (P(interaction) = .03). CONCLUSIONS Heavy, daily drinking increased the risk of high-grade prostate cancer. Heavy drinking made finasteride ineffective for reducing prostate cancer risk.

Abstract
Alcohol is a risk factor for several types of cancer. However, the results for prostate cancer have been inconsistent, with most studies showing no association. Within the European Prospective Investigation into Cancer and Nutrition, detailed information were collected from 142,607 male participants on the intake of alcoholic beverages at recruitment (for 100% of the cohort) and over lifetime (for 76% of the cohort) between 1992 and 2000. During a median follow-up of 8.7 years, 2,655 prostate cancer cases were observed. Multivariate Cox proportional hazard models were used to examine the association of alcohol consumption at recruitment and average lifetime alcohol consumption with prostate cancer adjusted for age, center, smoking, height, weight, physical activity, and nonalcohol energy intake. Overall, neither alcohol consumption at baseline nor average lifetime alcohol consumption was associated with the risk for prostate cancer in this cohort of men. Men who consumed >or=60 g alcohol per day had a relative risk of 0.88 [95% confidence interval (95% CI) 0.72-1.08] compared with men with an intake of 0.1-4.9 g/d; the respective relative risk for average lifetime intake was 1.09 (95% CI, 0.86-1.39). For advanced prostate cancer (n = 537), the relative risks for >or=60 and 0.1-4.9 g alcohol per day at baseline were 0.98 (95% CI, 0.66-1.44) and 1.28 (95% CI, 0.79-2-07), respectively, for average lifetime intake. No statistically significant association was observed for alcohol intake from specific alcoholic beverages. Our results indicate no association between the consumption of alcohol and prostate cancer in this cohort of European men.

Abstract
An association between alcohol consumption and prostate cancer risk remains uncertain. Although some studies have found that heavy alcohol consumption is associated with increased risk, a recent study reported that red wine consumption is associated with reduced risk. We examined the association between alcohol use and prostate cancer among 34,565 men, 50-76 yr old, in the Vitamins and Lifestyle (VITAL) cohort in Washington State. Alcohol consumption was ascertained by baseline questionnaire between October 2000 and December 2002. Incident prostate cancers (n = 816) as of December 31, 2004, were identified through the Surveillance, Epidemiology, and End Results cancer registry. Men who consumed more than one drink per month had a small increased risk of prostate cancer (hazard ratio, HR = 1.20; 95% confidence interval, CI = 1.02-1.40) compared with men who drank no alcohol or less than one drink per month. White wine consumption was associated with increased risk (HR for any vs. no white wine consumption = 1.27; CI = 1.08-1.49). Red wine, liquor, and beer were not associated with prostate cancer nor was total alcohol consumed at ages 18, 30, and 45. Associations of alcohol use with prostate cancer are modest and complex. More detailed assessment of specific alcoholic beverages is warranted in future studies.

Abstract
OBJECTIVES To examine the association between alcohol and the risk of prostate cancer/benign prostatic hyperplasia (BPH) in a population with a wide range of alcohol consumption, using a hospital-based, case-control study. Data from several epidemiologic studies have allowed us to exclude a strong association between alcohol drinking and prostate cancer risk. However, limited information is available for BPH. Also, it is unclear whether various types of alcoholic beverages may have a different impact on risk. METHODS We conducted this hospital-based case-control study in Italy between 1991 and 2002. A total of 2663 men younger than 75 years had incident, histologically confirmed prostate carcinoma (1294 cases) or symptomatic obstructive BPH (1369 cases) (maximal flow rate less than 15 mL/s) refractory to medical treatment. A total of 1451 patients younger than 75 years were used as controls. Odds ratios and corresponding 95% confidence intervals were estimated using unconditional multiple logistic regression models including terms for age, center, education, body mass index, physical activity, and family history of prostate cancer. RESULTS Alcohol consumption showed no consistent association with prostate cancer risk, but a statistically significant inverse trend in risk for BPH. Compared with abstainers, the odds ratio was 0.88 for fewer than three drinks, 0.71 for three to four drinks, 0.79 for five to six drinks, and 0.65 for seven or more drinks per day. The patterns of risk were similar with reference to different alcoholic beverages. The inverse relation between elevated alcohol consumption and BPH was apparently stronger in subjects with a lower body mass index. CONCLUSIONS Alcohol drinking is unrelated to prostate cancer risk. The inverse relationship with BPH may be related to the hormonal correlates (ie, lower androgen levels) of heavy alcohol drinkers.

Abstract
Prostate cancer is a leading cause of mortality and morbidity worldwide. Despite years of study and effort, certain key questions remain unanswered, including how prostate cancer is best detected and diagnosed, how it is best treated, and how best to minimize the complications of treatment. The aim of this article is to briefly address these topics to shed light on the current best practices in prostate cancer screening, diagnosis, and surgical treatment of localized disease. We examine current trends in prostate cancer epidemiology and screening, including genetic and dietary risk factors and the newer prostate-specific antigen-derived screening modalities. Methods of diagnosis, including an overview of prostate biopsy technique and indications, and a brief review of relevant pathologic findings are provided. An in-depth analysis of traditional prostate cancer surgical management highlights the relevant advantages and disadvantages of radical retropubic and perineal prostatectomy. Complications of surgery, prognostic factors, and the many risk prediction models currently available are discussed. In all, this article aims to give the reader a broad overview of the basic elements of prostate cancer diagnosis and surgical treatment in the modem era.

Abstract
BACKGROUND Prostate cancer (PCa) is one of the most common male cancers, but the burden of this disease shows remarkable worldwide variation. The role of susceptibility low penetrance genes and environmental factors in the etiology of (PCa) is unclear, but may involve, in some cases, multiple alleles at multiple loci and environmental factors. STUDY OBJECTIVES To assess whether CYP1A1, GSTM1, GSTT1 susceptibility genotypes, smoking status and alcohol consumption factors contribute to PCa risk, gene-gene and gene-environment interactions were analyzed. DESIGN AND PARTICIPANTS We explored interactions on a multiplicative scale conducting a population-based case-control and a case-only study on 103 incident PCa patients and 132 unrelated controls. MAIN RESULTS The interaction odds ratios (IOR) for PCa risk were increased in men who had both susceptibility genotypes GST (M1; T1) null and CYP1A1-M1* in a case-control and case-only design (IOR(cc): 1.11; 95% CI: 0.12-10.02; IOR(cc): 6.23; 95%, CI: 0.51-75.89; IOR(co): 2.80; 95% CI: 0.44-17.45 and IORco: 2.65; 95%, CI: 0.30-25.40). No clear evidence for interaction on a multiplicative scale between smoking status, alcohol consumption and genetic polymorphisms in PCa risk was observed. CONCLUSIONS Our findings suggest that the interaction between genetic polymorphisms in GST (T1; M1) and CYP1A1-M1* would play a significant role as a modifying factor on PCa risk in Chilean people. However, these preliminary exploratory results should be confirmed in a larger study.

Abstract
The harmful influence of the chronic alcohol ingestion on the male reproductive system leads to important alterations including hypogonadism and feminization, besides the morphological and functional disorganization of the different sexual glands. So, the aim of this study was to analyse the structural changes on the ventral lobe of the prostate of rats with hormonal replacement associated to chronic alcohol ingestion. A total of 30 rats (Rattus norvegicus albinus) was divided into three groups: control-received water; alcoholic-received ethanol diluted to 20% and hormone-treated alcoholic-received ethanol diluted to 20% associated with the administering of testosterone (5mg/kg of weight) during the last 30 days of treatment. After 150 days of treatment, the animals were sacrificed, the prostate removed and submitted to transmission and scanning electron microscopies, histochemical analysis for acid phosphatase, testosterone level and stereologic analysis. In the alcoholic group the results demonstrated reduction of the total cellular volume and disorganization of the organelles involved in the secretory process. It was characterized a partial recovery of the cellular volume after treatment with testosterone. It was concluded that the ethanol impaired the cellular morphology and the hormonal replacement by itself did not bring about efficient remodeling of the organelles responsible for the secretory process.

Abstract
Prostate cancer incidence and mortality rates vary worldwide. In the United States, prostate cancer is the most common malignancy affecting men and is the second-leading cause of cancer death. Risk of developing prostate cancer is associated with advancing age, African American ethnicity, and a positive family history, and may be influenced by diet and other factors. The incidence of prostate cancer increased sharply after the introduction of widespread screening for prostate-specific antigen (PSA), although rates have now returned to levels seen before that time. PSA screening has been associated with a shift toward diagnosis of earlier-stage disease, but this has not been accompanied by a shift toward a lower histologic grade. Although overall prostate cancer mortality rates decreased during the 1990s, it was largely because of reductions in deaths among men diagnosed with distant disease. In contrast, mortality rates for men diagnosed with localized or regional disease increased gradually during most of the 1990s before decreasing slightly among white men and reaching plateaus among African Americans.

Abstract
A variety of lifestyle factors, including physical activity, artificial sweeteners, alcohol consumption and smoking, have been reported to contribute to the risk of developing urological malignancies. A great number of epidemiological studies suggest that sports and physical activity may have a preventive influence on genitourinary tumours, especially on the incidence of prostate cancer. Smoking appears to be the most relevant lifestyle factor significantly increasing both incidence and mortality from bladder cancer. Furthermore, there is evidence implicating an association between tobacco use and kidney cancer. In contrast, prostate and testicular cancers are unlikely to be linked to tobacco use. As far as alcohol is concerned, most studies indicate that neither amount nor type of alcohol seems to be clearly associated with a risk of developing urological malignancies. However, some more recent cohort studies suggest a moderately increased risk for prostate and bladder cancer for specific types of alcohol. On the other hand, there is evidence that moderate alcohol consumption may even protect women from developing renal cancer. Since the introduction of artificial sweeteners, reports of potential cancer risks have circulated periodically through the mass media. The wide distribution of these agents and the fact that mostly combinations of the different compounds are added to a broad variety of food, drinks, drugs, and hygiene products complicates a systematic analysis of their potential impact on the development of urological malignancies. Nevertheless, so far not a single study has convincingly demonstrated a statistically significant risk of bladder cancer due to the consumption of artificial sweeteners. This survey demonstrates that the individual assessment of lifestyle factors not only may identify groups with an increased risk for urological malignancies but also clearly displays a potential for tumour prevention.
