A systematic review of the arsenic content of the normal human prostate gland

Abstract:

Background: The prostate gland is subject to various disorders. The etiology and pathogenesis of these diseases remain not well understood. Moreover, despite technological advancements, the differential diagnosis of prostate disorders has become progressively more complex and controversial. It was suggested that the arsenic (As) level in prostatic tissue plays an important role in prostatic carcinogenesis and its measurement may be useful as a cancer biomarker. These suggestions promoted more detailed studies of the As content in the prostatic tissue of healthy subjects.

Objective: The present study evaluated by systematic analysis the published data for as content analyzed in prostatic tissue of “normal” glands.
Methods: This evaluation reviewed 1927 studies, all of which were published in the years from 1921 to 2020 and were located by searching the databases Scopus, PubMed, MEDLINE, ELSEVIER-EMBASE, Cochrane Library, and the Web of Science. The articles were analyzed and “Median of Means” and “Range of Means” were used to examine heterogeneity of the measured As content in prostates of apparently healthy men. The objective analysis was performed on data from the 16 studies, which included 471 subjects.
Results: It was found that the range of means of prostatic as content reported in the literature for “normal” gland varies widely from 0.00039 mg/kg to <0.017 mg/kg with median of means 0.0031 mg/kg on a wet mass basis.
Conclusion: Because of small sample size and high data heterogeneity, we recommend other primary studies be performed.
