Although gender is widely known risk factor used as a covariate in numerous studies number of investigators have searched the explanations to unravel gender diversities in bladder cancer. In addition we found that the association between sex and bladder CSS was modified by poverty with women in the highest poverty category experiencing the highest risk of death from bladder cancer.
Gender Specific Differences In Recurrence Of Non Muscle Invasive Bladder Cancer A Systematic Review And Meta Analysis European Urology Focus
091-096 compared with men but more likely to die from bladder cancer HR.
Gender disparity in bladder cancer risk. Potential molecular mechanisms include disparate metabolism of carcinogens by hepatic enzymes between men and women resulting in differential exposure of the urothelium to carcinogens. Understanding the gender disparity in bladder cancer risk. The primary goal of the study was to investigate the impact of gender disparity on cancer-specific death risk after radical cystectomy in urothelial bladder carcinoma population.
Of the two preclinical studies. Other commonly reported symptoms are urinary frequency urgency or lower urinary tract symptoms. We look at some of the statistics and as well as the anatomy.
Author Yuesheng Zhang 1 Affiliation 1 a Department of Cancer Prevention and Control Roswell Park Cancer Institute Buffalo New York. Only analytic cohort settings are accorded with our purpose. Understanding the factors associated with gender disparities in bladder cancer presentation evaluation and management could thus facilitate improvements in the timeliness and intensity of health care delivery.
First we removed the duplicated articles in the two databases and scanned the titles to excluded non-English. To explore the association between 2D4D ratio and BC. Interestingly despite similar smoking intensity men were diagnosed with bladder cancer approximately four times more commonly than women30Inapreviousstudythatcontrolledforsmoking and occupational hazards the gender-related disparate risk of bladder cancer persisted 31.
Animal studies with bladder carcinogens recapitulate the gender disparity in BC risk seen in humans and these studies have also shown a gender-related difference in liver metabolism of bladder carcinogens. Men are at a higher risk of developing bladder cancer but women present with more advanced disease and have more unfavourable outcomes. Macroscopic hematuria is a common symptom of bladder cancer and is typically present in 80 of patients 3.
Gender disparity in bladder cancer is a complex issue that likely stems from diagnostic delays therapeutic differences and possibly biologic factors. Bladder cancer risk 30. It can be a just a brief overview.
Similarly a prior meta-. To evaluate this we applied CSS and CSM. On the left hand panel.
The phenomenon should be presented in the focus of variety of elements including differences in exposures to risk factors and potential gender related mechanisms of chemical compounds. Despite the higher incidence of bladder cancer among males discussed above women consistently have more advanced tumors at the time of diagnosis. The impact of sex hormones and liver on bladder susceptibility to carcinogens J Environ Sci Health C Environ Carcinog Ecotoxicol Rev.
For Hispanics the incidence of bladder cancer is declining and survival rates are comparable to Whites. Gender differences in bladder cancer incidence are related to biologic and epidemiologic factors such as disparate metabolism of carcinogens hormonal factors and exposure risk including cigarette smoking and occupational exposure 8 11. We summarize the evidence and most recent findings on gender-specific differences in bladder cancer incidence diagnosis treatment and outcome spotlighting the gender disparities in genetic and hormonal risk factors pelvic anatomy diagnostic setting and surgical choices.
A total of 497 articles were published from which 133 met the inclusion criteria. So we know that there is this gender gap when it comes to urothelial cancer. Males have a threefold to fourfold higher risk of bladder cancer.
Each of these areas provides opportunities for improvement and for the eventual elimination of the gender divide. Three articles reported separate outcome data for male and female. In addition the activity of the sex steroid hormone pathway may play a role in bladder cancer.
Gender Disparities for Women with Bladder Cancer So lets talk a little bit about gender differences in bladder cancer and some of the risks. 2 2 preclinical cell-based and 131 98 clinical studies Fig. Important risk factors for bladder cancer are age male gender smoking and occupational exposures with cyclic organic chemicals 2.
20131 15 of the clinical studies reviewed did not disclose the number of patients according to sex. Exposure to prenatal sex steroids as indicated by the ratio of the second to fourth digit length 2D4D has been linked to the risk of onset of cancer while sex steroids may expand the gender disparity in bladder cancer BC morbidity. It has been shown that the gender difference in bladder cancer incidence is independent of differences in exposure risk including smoking status.
Sex Disparity Exists in Bladder Cancer Research. Among bladder cancer patients the bulk of research pertaining to racial and ethnic disparities involves Whites Hispanics and African Americans Table 1. While it is possible that differences in biologic pathways are responsible for these trends gender disparities for the timeliness and thoroughness of initial.
We reviewed the literature published on PubMed between 1981 and 2018. We summarize the evidence and most recent findings on gender-specific differences in bladder cancer. There were a total of 9255352 deaths due to bladder cancer with median follow-up time of 44 years.
Gender disparities in bladder cancer presentation and evaluation. After adjusting for confounding variables women were statistically significantly less likely to die from any cause HR. Similar to prior literature we found that female sex black race and higher poverty categories were independently associated with an increased risk of bladder cancer-specific death even after adjusting for clinical characteristics.
We also found that after adjusting for confounding variables. Many lines of evidence strongly suggest that the gender-related difference in liver metabolism of bladder carcinogens translates into a difference in bladder exposure to the carcinogens which in turn may function as one of the key drivers of the gender disparity in BC risk. Partnerships with primary care providers and gynecologists should remain a priority to improve education and understanding of the.
Although epidemiologic and genetical studies have underlined the multifactorial aetiology and gender-related differences of bladder cancer there is lack of evidence-based recommendation for gender-specific management of bladder cancer. In turn such efforts offer the potential to reduce the magnitude of the gender-based disparities observed for bladder cancer outcomes.
