Abstract

Abstract : Background and Aims: Exposure to metals may promote the risk for cancers. We evaluated the associations of a broad spectrum of metals with gallbladder cancer (GBC) and gallstones. Approach and Results: A total of 259 patients with GBC, 701 patients with gallstones, and 851 population‐based controls were enrolled in Shanghai, China. A metallome panel was used to simultaneously detect 18 metals in serum through inductively coupled plasma–mass spectrometry. Logistic regression models were used to estimate crude or adjusted odds ratios (ORadj ) with 95% confidence intervals (CIs) for the association between metal levels and gallbladder disease. Among the 18 metals tested, 12 were significantly associated with GBC and six with gallstones ( P corrected < 0.002). Boron, lithium, molybdenum, and arsenic levels were associated with GBC compared to gallstones as well as with gallstones compared to population‐based controls. Elevated levels of cadmium, chromium, copper, molybdenum, and vanadium were positively associated with GBC versus gallstones; and the ORadj for the highest tertile (T3) compared to the lowest tertile (T1) ranged from 1.80 to 7.28, with evidence of dose–response trends ( P < 0.05). Arsenic, boron, iron, lithium, magnesium, selenium, and sulfur were inversely associated with GBC, with the T3 versus T1 ORadj ranging from 0.20 to 0.69. Arsenic, boron, calcium, lithium, molybdenum, and phosphorus were negatively associated with gallstones, with the T3 versus T1 ORadj ranging from 0.50 to 0.75 ( P < 0.05). Conclusions: Metals were associated with both GBC and gallstones, providing cross‐sectional evidence of association across the natural history of disease. Longitudinal studies are needed to evaluate the temporality of metal exposure and gallbladder diseases and to investigate the mechanisms of disease pathogenesis.
