WebTalc is a mineral made up mainly of magnesium, silicon, and oxygen. Lung tumors occurred at very high administered doses that appeared to cause particle overload and using micronized talc (not typical of talc mining or milling exposures, or of cosmetic talcum powder products), limiting the ability to extrapolate these findings to relevant exposures in humans. Examination of talcum products commonly available on retail shelves found fiber contents ranging from 8 to 30% by count, with an average of 19%, and the levels of cobalt, nickel, chromium and manganese were low. Although one meta-analysis (5) reported a statistically significant meta-SMR of 1.45 (95% CI: 1.221.72) for non-asbestiform talc and lung cancer, this review included several occupational cohorts with mixed exposures to possible lung carcinogens such as silica, asbestos, and radon (miners) resulting in high heterogeneity across reported study results.

Raw talc ores were, We conducted a systematic review to assess the potential pulmonary carcinogenicity of inhaled talc in humans. We performed literature searches using PubMed and Web of Science and used existing agency reviews as a basis for cross-referencing critical studies. Two animal studies examining inflammation in the lungs reported increased early inflammatory markers. Occupational studies in which talc was known to contain asbestos are not included. (25) reported that talc did not cause significantly increased frequency of sister-chromatid exchange or increased DNA repair synthesis in rat pleural mesothelial cells, relative to positive or negative controls (16). Chang CJ, Tu YK, Chen PC, Yang HY.

All authors contributed to manuscript revision, read, and approved the submitted version. The talc powder contains 95% of hydrated magnesium silicate; associated minerals include chlorites (hydrated aluminum and magnesium silicates), magnesite (magnesium carbonate), Give explanations- how can we tell someone is sad? Talc has been reported to cause fever in 16 to 69% of patients. When considered together, the moderate confidence in study findings, large study populations, long duration of follow up, and consistency of null findings indicate that talc exposure is not associated with mesothelioma. 37. (2019) 61:91623. Relative to cohort members with the lowest cumulative respirable dust exposure (0 to <95.1 mg/m3), individuals in the two highest cumulative exposure groups had slightly reduced lung cancer risk (RR for cumulative exposure of 95.1-<987 mg/m3 = 0.8; 95% CI: 0.31.9, and RR for cumulative exposure of 987+ mg/m3 = 0.5; 95% CI: 0.21.3). 0000011107 00000 n Overall, in available animal studies, there is indeterminate evidence that talc is associated with lung tumors in rodents based on negative findings in several high-quality studies and species, but positive results in a single species and sex (female rats) exposed to high doses of micronized talc that caused particle overload conditions. What will the Test of Abstract Language Comprehension assess? (2018) 92:25167. As with other particles, one postulated carcinogenic MOA for talc is chronic inflammation resulting from the overwhelming of particle clearance mechanisms (i.e., phagocytosis), long-term tissue irritation and release of inflammatory chemokines and cytokines, and reactive oxygen species (ROS) formation.

Beck BD, Feldman HA, Brain JD, Smith TJ, Hallock M, Gerson B, et al. Version 1, 0. Markers of inflammation also have been observed in the lungs of rats after talc exposure, but one of the only available mechanistic studies utilized a route of exposure (i.e., intratracheal instillation) that is not comparable to inhalation exposures. (30) reported no increased lung cancer mortality among French (SMR = 1.23; 95% CI: 0.761.89) and Austrian (SMR = 1.06; 95% CI: 0.432.19) talc mining and processing employees (30). Mortality experiences among talc workers: a follow-up study. Emory TS, Maddox JC, Kradin RL. The Italian, Norwegian, French, and Austrian talc mines all produced talcs described as non-asbestiform with various accessory minerals including small amounts of chlorite and quartz (30, 50, 52). Our search identified six studies assessing talc exposure and tumor formation in animal models.

However, the lung tumors occurred only in female rats exposed at a dose also inducing significant chronic lung toxicity and high lung talc burden, such that the maximum tolerable dose may have been exceeded (21). No specific mention of mesothelioma was recorded on the death certificates. 0000007801 00000 n The 17 occupational cohort study reports evaluated for study quality encompassed talc miners and millers in New York State (4147), Italy (1, 4851), Norway (52, 53), France and Austria (30) and Vermont (5456).

Histologic evaluation of lung tissue revealed no exposure-related lesions except for a modest, diffuse increase in free macrophages within alveolar spaces of both rats and mice exposed to the highest concentration of talc. A flow chart for the overall tiering approach used for cohort studies is provided as an example in Figure 1. There was one lung carcinoma found in the group exposed to talc for 3 min/day for 30 days, and one lung carcinoma found in the 300-day control group.

Mortality patterns among miners and millers of non-asbestiform talc: preliminary report. Integrating the evidence demonstrating a lack of statistically significant increases in mesothelioma in inhalation rodent bioassays, the null findings in the higher-quality epidemiological literature, and the lack of evidence of a plausible MOA, we conclude that there is suggestive evidence of no association between inhaled talc and mesothelioma at human-relevant exposure levels. s xr%LD%U\C The Cosmetic Ingredient Review Expert Panel (Panel) assessed the safety of talc for use in cosmetics. doi: 10.1002/ajim.4700170408, 53.

Pulmonary cancer (lung cancer and mesothelioma) mortality generally was ascertained via death certificates coded by certified nosologists. This substance is among those substances identified as priorities for In an in vivo OECD Guideline 478 Dominant lethal test, male Sprague-Dawley rats were exposed via gavage to a single dose or one dose/day for 5 days of 300, 3,000, or 5,000 mg/kg talc. The assessment can be used with children from the age of 2+. Additional searches were run using filters for animal/toxicology studies, and for mechanistic/mode of action (MOA) studies, using search terms including, but not limited to the following: micronuclei, sister chromatid exchange, chromosome aberrations, DNA adduct, DNA methylation, inflammation, mechanism, and MOA. Kleinfeld and coworkers published two proportionate mortality studies on miners and millers in upstate New York potentially exposed to talc with asbestiform or non-asbestiform amphibole minerals, largely in response to reports of fibrogenic pneumoconiosis (44, 45). 55. The SMRs for the eligible cohorts ranged from 0.92 in a Norwegian cohort [] to 4.50 in a Chinese Ierardi AM, Best EA, Marsh GM. Talc concentrations of 10.8 mg/m3 were administered for 7.5 h per day, 5 days per week; 48 animals from each group were exposed for 3 months, 24 animals for 6 months, and 24 animals for 12 months with cumulative doses of approximately 4,100, 8,200, and 16,400 mg/m3-h for the 3-month, 6-month, and 12-month exposure durations, respectively.

Inhalation of talc induces infiltration of macrophages and upregulation of manganese superoxide dismutase in rats. A systematic approach for evaluating the quality of experimental toxicological and ecotoxicological data. In both the talc and chrysotile exposure groups, fibrosis was observed to a similar extent, with minimal to no fibrosis observed in the air-exposed control group. Because the one malignant mesothelioma in the Vermont cohort was identified following a focused search of death certificates for the cohort but not the referent group, its inclusion results in a conservative bias. The estimated average SMR for lung cancer was 1.45 (95% CI: 1.221.72, ) among the workers exposed to talc.Figure 2 shows the forest plot corresponding to the summary lung cancer SMR calculated in the meta-analysis. Systematic review of the scientific evidence on ethylene oxide as a human carcinogen. The tiering system allows for preferentially weighting specific quality domains (e.g., exposure characterization) first, followed by more secondary determinants of study quality. (1987() 87:22234. Detailed data abstraction and study quality evaluation, adapting the US Toxic Substances Control Act (TSCA) framework, were central to our analysis. Chemically, talc is a hydrous magnesium silicate with a chemical formula of Mg 3 Si 4 O 10 (OH) 2. According to information reported under section 71 Phone: +1 (800) 627-7271 (2002) 46:57585.
