Cadmium intake as a prognostic factor in endometrial cancer : a Swedish cohort-based study

• Metalloendocrinology is a new interdisciplinary field, which was established due to the importance of connections between inorganic chemicals and hormonal mechanisms. The role of cadmium in hormone-related tumors is an excellent example of this connection, as cadmium mimics estrogen in the human body. Since endometrial cancer (EC) is hormonerelated, it is well-suited for assessing the estrogenic effects of cadmium. Therefore, the present study aims to explore the role of dietary cadmium intake in the progression-free survival (PFS) and overall survival (OS) in women with EC. Dietary cadmium intake was estimated based on a large cohort of Swedish women (n ¼ 416) with EC. Median dietary cadmium intake was then analyzed in relation to different tumor characteristics and clinical outcomes. Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Median daily dietary cadmium intake in the cohort was 13.1 lg (interquartile range 25%-75%¼6.4). High dietary cadmium intake (lg/day) was associated with significantly decreased OS in the study cohort (HR ¼ 0.956, 95% CI ¼ 0.914- 1.001, p ¼ 0.05). Dietary cadmium intake was not associated with PFS (HR ¼ 0.975, 95% CI ¼ 0.924-1.028, p ¼ 0.348). Therefore, our results indicate that high dietary cadmium intake could be associated with poor outcome in women with EC.
