Comparison of Serum Strontium and Antimony Levels in Patients with Esophageal Cancer and Healthy People
Authors
Abstract:
ABSTRACT Background and Objective: Esophageal cancer is the third most common type of cancer in Iran. Studies on water, soil, grains, waste and sediments in Golestan Province have shown that the environmental concentrations of antimony and strontium are increased in areas with high incidence rate for cancer. The carcinogenic effects of strontium have been reported, but carcinogenicity of antimony is still unclear. Since there is not enough information regarding the relationship between the concentration of strontium and antimony and prevalence of esophageal cancer in the province, this study aimed to evaluate serum levels of these elements in patients with esophageal cancer using atomic absorption spectroscopy. Methods: This study was performed on 30 patients with esophageal squamous cell carcinoma and 30 healthy matched controls. After sampling, concentrations of strontium and antimony were measured using atomic absorption spectroscopy. Results: Half of the esophageal cancer patients and control participants were male. The mean age of patients and controls was 66 ± 13 and 64 ± 8 years, respectively. The mean serum concentration of strontium in patients and controls was 24.18 ± 1.62 and 24.08 ± 1.46 μg/L, respectively. The mean serum concentration of antimony in patients and controls was 18.61 ± 1.48 and 18.98 ± 1.93 μg/L, respectively. No statistically significant difference was observed between the serum concentrations of the two elements in patients and controls. Conclusion: There is no difference between serum levels of strontium and antimony in cancer patients and healthy controls, which could be due to tissue accumulation. Keywords: Antimony, Strontium, Esophageal Neoplasms.
