Abstract Introduction: Trichomonas vaginalis infection is one of the most widespread sexually transmitted infections in the world. There are approximately 276 million cases worldwide. Most men remain undiagnosed and untreated because they are asymptomatic. The chronic inflammation induced by persistent infection may increase the risk of developing genitourinary cancers. In this study, we aimed to investigate the association between trichomoniasis and benign prostate hyperplasia (BPH), prostate cancer (PCa), and bladder cancer (BC) in Taiwan.Material and method: We designed a case-control study by using the database of the National Health Insurance program in Taiwan. We used the International Classification of Diseases, 9th Revision classifications to classify all the medical conditions in the case and control groups. All odds ratios (ORs) and 95% confidence intervals (CIs) were analyzed using multivariable logistic regression to adjust for all comorbidities and variables.Result: From 2000 to 2015, we enrolled a total of 62,544 individuals as the case group and 187,632 as the control group. Trichomoniasis exposure had a significant association with BPH and PCa (adjusted OR: BPH = 2.685, 95% CI = 1.233–4.286, P = 0.013; PCa = 5.801, 95% CI = 1.296–26.035, P = 0.016). The relative risk was much higher if patients had both trichomoniasis and depression (adjusted OR = 7.682, 95% CI = 5.730–9.451, P < 0.001).Conclusion: Men with trichomoniasis had a significantly higher risk of developing BPH and PCa than those without. Healthcare professionals should not only pay more attention to disease treatment, but also to public health education.

Abstract Purpose: The aim of this study was to investigate occupational risk factors associated with bladder cancer. Materials and Methods: In this case–control study, control group included patients who referred to a specialized clinic in the same city and hospitals where patients had been registered. Data were entered into SPSS software. Odds ratios (OR) were calculated for occupational variables and other characteristics. Then, using logistic regression, the association between cancer and drugs was studied while smoking was controlled. Results: Cigarette smoking, even after quitting, was also associated with bladder cancer (OR = 2.549). Considering the classification of occupations, the OR of working in metal industry in patients was 10.629. Multivariate analysis showed that use of the drug by itself can be a risk factor for bladder cancer. Drug abuse together with the control of smoking increased the risk of bladder cancer by 4.959. Conclusion: According to the findings of this study, contact with metal industries such as welding, and working with tin was found as a risk factor for bladder cancer. In addition, cigarette smoking and opium abuse individually were associated with bladder cancer.

This study aims to explore the association between fruit and vegetable intake, high fat, body mass index (BMI) score, physical activity, and the occurrence of prostate cancer among Jordanian men. A case-control study was conducted in three large referral hospitals. The sample included 165 prostate cancer patients in the case group and 177 healthy participants in the control group. The results showed that smoking (odds ratio [OR] = 0.32; 95% confidence interval [CI] = [0.18, 0.57]), a history of prostate infection (OR = 0.21; 95% CI = [0.11, 0.38]), high-fat intake (OR = 0.44; 95% CI = [0.23, 0.85]), and increased mean of BMI (OR = 1.08; 95% CI = [1.02, 1.13]) increased the likelihood of developing prostate cancer. Healthy diet and giving up smoking are recommended, as they may contribute to a reduction in the incidence of prostate cancer. More randomized clinical trials in this area are needed to strengthen the available evidence and reduce the effects of confounding variables.

435 Background: Oxidative stress may be involved in tumorigenesis processes. Uric acid is an important natural antioxidant that may reduce oxidative stress. Allopurinol is a commonly used uric acid lowering agent. There are conflicting data regarding the association between allopurinol use and cancer incidence. In the present nested case control study, we aimed to evaluated the association between allopurinol use and urologic malignancies in a large western population. Methods: conducted a nested case-control study within a population-representative database from the United Kingdom (THIN). Study cases were defined as individuals with any diagnostic code of prostate cancer, bladder cancer, or renal cell carcinoma. For every case, four eligible controls were matched on age, gender, practice site, time of diagnosis, and duration of follow-up. Exposure of interest was any allopurinol use prior to cancer diagnosis. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for urologic malignancies were estimated using conditional logistic regression. Adjustment was performed for factors including smoking, BMI, and diabetes. Results: The study population included: for bladder cancer 13440 and 52421 matched controls, prostate cancer 27212 cases and 105940 controls, RCC 1547 cases and 6066 controls. Allopurinol use was associated with a significantly increase of risk for bladder cancer (adjusted OR 1.2, 95%CI 1.09-1.32, p<0.001). prostate cancer (adjusted OR 1.1, 95%CI 1.03-1.,17, p=0.003), RCC (adjusted OR 1.32, 95%CI 1-1..75, p=0.05). In a sensitivity analyses we observed similar associations when alopurinol use was initiated more than two years prior to cancer diagnosis, for bladder cancer (adjusted OR 1.2, 95%CI 1.08-1.33, p=0.001), prostate cancer (adjusted OR 1.09, 95%CI 1.02-1.16, p=0.01), RCC (adjusted OR 1.09, 95%CI 0.78-1.53, p=0.62). Conclusions: Allopurinol use may be associated with an increased risk for urologic malignancies.
