Serum selenium level and other risk factors for breast cancer among patients in a Malaysian hospital

In a recent prospective study, we reported an association between a low serum selenium level and five-year survival among breast cancer patients. We now have updated the cohort to include 10-year survival rates. A blood sample was obtained from 538 women diagnosed with first primary invasive breast cancer between 2008 and 2015 in the region of Szczecin, Poland. Blood was collected before initiation of treatment. Serum selenium levels were quantified by mass spectroscopy. Each patient was assigned to one of four quartiles based on the distribution of serum selenium levels in the whole cohort. Patients were followed from diagnosis until death or last known alive (mean follow-up 7.9 years). The 10-year actuarial cumulative survival was 65.1% for women in the lowest quartile of serum selenium, compared to 86.7% for women in the highest quartile (p < 0.001 for difference). Further studies are needed to confirm the protective effect of selenium on breast cancer survival. If confirmed this may lead to an investigation of selenium supplementation on survival of breast cancer patients.

Serum Selenium Level

Background: Acute stress response to heart surgery can cause major morbidity in patients. The trace of selenium is useful for preventing heart damage. Although the trend of selenium changes is of high importance for body balance, the usefulness of routine use and effectiveness of this element for patients under open-heart surgery is still unclear. Objectives: This study aimed at assessing serum selenium level before and after open-heart surgery and the relationship between selenium trace and patient outcome. Methods: This prospective analytical study was performed on 100 patients undergoing open-heart surgery using cardiopulmonary bypass (CPB). In all patients, the serum level was measured at a predetermined time (before surgery and one and two days after surgery). Then, the relationship between serum selenium and patient outcome was assessed. Results: The mean serum selenium level in patients on admission was 72.90 ± 14.62 μg/L, one day after surgery was 71.20 ± 15.84 μg/L, and two days after surgery was 71.54 ± 15.97 μg/L. Serum selenium levels were inversely and significantly associated with age (r = -0.183; P = 0.034, 013) duration of surgery (r = -221 and P = 0.014), duration of intensive care unit stay (r = 0.204, P = 0.021), and duration of CPB (r = 0.223, P = 013). Conclusions: Based on this study’s results, a low level of selenium can affect patients’ outcomes after open-heart surgery.

Serum Selenium Level

Melanoma is one of the most aggressive human malignancies. The determination of prognostic biomarkers is important for the early detection of recurrence and for the enrollment of the patients into different treatment regimens. Herein, we report the 10-year survival of 375 melanoma patients depending on their serum selenium levels. The study group was followed up from the date of melanoma diagnosis until death or 2020. Patients were assigned to one of four categories, in accordance with the increasing selenium level (I–IV quartiles). The subgroup with low selenium levels had a significant lower survival rate in relation to patients with high selenium levels, HR = 8.42; p = 0.005 and HR = 5.83; p = 0.02, for uni- and multivariable models, respectively. In the univariable analysis, we also confirmed the association between Breslow thickness, Clark classification and age at melanoma prognosis. In conclusion, a low serum selenium level was associated with an increased mortality rate in the 10 years following melanoma diagnosis. Future studies in other geographic regions with low soil selenium levels should be conducted to confirm our findings.

Low serum selenium levels are commonly observed in critically injured multiple trauma patients. This study aimed to identify the association between initial serum selenium levels and in-hospital infectious complications in multiple trauma patients. We retrospectively reviewed multiple trauma patients admitted between January 2015 and November 2017. We selected 135 patients whose serum selenium levels were checked within 48 h of admission. Selenium deficiency was defined as a serum selenium level <70 ng/mL. Survival analyses of selenium deficiency and 30-day mortality were performed. Multivariate logistic regression analysis was performed to identify the association between initial serum selenium level and in-hospital infectious complications. Thirty-day mortality (8.3% vs. 0.0%; p = 0.018) and incidence rates of pneumonia (66.7% vs. 28.3%; p < 0.001) and infectious complications (83.3% vs. 46.5%; p < 0.001) were higher in patients with selenium deficiency than in patients without selenium deficiency. Kaplan–Meier survival cures also showed similar results (log rank test, p = 0.021). Of 135 patients, 76 (56.3%) experienced at least one infectious complication during admission. High injury severity score (ISS, odds ratio (OR) 1.065, 95% confidence interval (CI) 1.024–1.108; p = 0.002) and selenium deficiency (OR 3.995, 95% CI 1.430–11.156; p = 0.008) increased the risk of in-hospital infectious complications in multiple trauma patients. Patients with selenium deficiency showed higher 30-day mortality and higher risks of pneumonia and infectious complications.
