The Association Between Occupational Cadmium Exposure and Prostate Cancer in Worker: Evidence-Based Case Report

Introduction. Cadmium has an important role because widely used in various industries. Cadmium penetrates and can be accumulated in human body including prostate. Cadmium is highly toxic and can cause human carcinogens. The aim of this evidence-based case report is to get an appropriate answer about the association between occupational cadmium exposure and prostate cancer in worker. Method. The literature searching was conducted through PubMed, Scopus and Cochrane Library. The keywords used were cadmium, cancer, prostate, work* and occupation*.The selection of articles was performed using the defined inclusion and exclusion criterias. Then, they were critically appraised using relevant criteria by the Oxford Center for Evidence-Based Medicine for etiological study or systematic review. Result. Two relevant and valid articles with systematic review and meta-analysis study design were included. Studies by Ju-Kun, et al. showed that the combined standardized mortality ratio of the association between Cd exposure and risk of prostate cancer was 1.66 (95% CI 1.10–2.50) in populations exposed to occupational Cd. While a study by Chen, et al. showed that workers with cadmium exposure have more risk for prostate cancer than general population but was not significant statistically with the weighted OR in case-control studies was 1.17 (95%CI [0.85-1.62]), and the weighted standardized mortality ratio (*100) in cohort studies was 98 (95%CI [75-126]). Conclusion. The current evidences do not show sufficient evidence to ensure that cadmium exposure can cause prostate cancer in worker.
