Questions relate to the immediate environment and require the child to think concretely e.g. 0000008097 00000 n Two adenomas (not considered cancerous) were observed in talc-exposed animals, 13 lung tumors were found in chrysotile-exposed animals, and one adenoma occurred in the air-exposed control group. Our expert speech and language therapists provide a range of services for children with eating, drinking and swallowing difficulties, alongside our professionals multidisciplinary team. Roggli VL, Carney JM, Sporn TA, Pavlisko EN. Mortality among workers at a talc mining and milling facility. In summary, lung cancer mortality was not elevated among most of the cohorts of talc miners and millers exposed to high levels of respirable talcs and accessory minerals. In female rats, there was an increased incidence of alveolar/bronchiolar adenomas and carcinomas of the lung and pheochromocytomas of the adrenal gland. Exposure characterization was considered the most critical study quality domain in the quality evaluation of lung cancer studies. Web2 Using the criterion of complete success (no reaccumulation of pleural fluid clinically or radiologically), talc (2.510 g) was found to be the most effective agent, and therefore assessment of pain remains problematic. This approval level enables you to buy our assessments requiring A or B qualification levels. talc products.14 The requested labeling was a warning that talcum powder causes cancer in laboratory animals; frequent talc application in the female genital area increases the risk of ovarian cancer. Wehner et al. An overview of our methods is provided below, and an example of their application can be seen in a recent review on ethylene oxide (9). Across all cohort studies, observed numbers of deaths for site-specific cancers among talc miners and millers (either combined or separately) were compared with expected numbers based on national and/or regional reference rates. In its most recent review of talc, the International Agency for Research on Cancer (IARC) concluded [t]here is inadequate evidence in humans for the carcinogenicity of inhaled talc (4). Reg Tox Pharm. Emory TS, Maddox JC, Kradin RL. %PDF-1.4 % 10. In summary, no excess of malignant mesothelioma has been reported in any of the available epidemiological studies of talc miners and millers heavily exposed to talc. Two nested case-control studies were conducted in tandem with occupational mortality analyses (30, 31). Simplified ceiling rule and reworded items for clarity. EPA Doc. The safety of talc has been the subject of much debate through the years, partly because the relationship between talc and asbestos is commonly misunderstood. 46. WebICH Q3D Pre-Step 2 Draft Guideline Incorporates Risk Assessment, Risk Management and Risk Mitigation concepts Testing is not the default; however, where necessary Methods are outside the scope of ICH Q3D Appropriate, validated analytical methods should be used Tests should be specific for each metal (e.g. 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. (48) updated the cohort and observed 44 lung cancers from 1946 through 1995 (SMR = 1.07; 95% CI: 0.731.50 for miners and SMR = 0.69; 95% CI: 0.341.23 for millers) (48). Int J Toxicol. Specifically, this framework involves reviewing and evaluating studies according to specific quality domains (e.g., outcome assessment and exposure characterization), each of which includes two to seven individual metrics assessing specific study features. Mortality from lung cancer was slightly lower than expected for the entire cohort. 7.2 Exposure assessment. However, the authors noted that these tumors were metastatic and that there were no primary neoplasms found in the respiratory system. Using detailed employment histories and a job exposure matrix, cumulative talc exposures were estimated, and each cohort member was assigned a concentration of low (2.5 mg/m3), medium (10 mg/m3), or high (40 mg/m3). Cincinnati, OH: U.S. Dept. Malignant mesothelioma following repeated exposures to cosmetic talc: a case series of 75 patients. exposure to the perineal area from the use of certain products containing talc is a possible cause of ovarian cancer. The body of epidemiological evidence is reasonably large and robust for lung cancer and mesothelioma and provides the most weight in the evidence integration, complemented by the number of high-quality experimental animal carcinogenicity bioassays, as well as the lack of convincing mechanistic evidence. We provide specialist speech and language therapy services for children with voice difficulties.

WebThe final assessment for talc found two possible health concerns. Webinstruction guide: circle = 1, numbers = 2, hands = 2 if all correct). DAYC-2 was normed on a national sample of 1,832 children. Acta Oncol. Further, the physicochemical properties of non-fibrous talc (e.g., inertness) and recent evaluations of potential MOAs indicate talc poses little to no concern for carcinogenic effects in humans, especially at less than lung overload exposures. Some of the popular cosmetic ingredients discussed in this paper may exert a negative influence on human health, and many of these harmful effects have been discovered recently. 20 Articles, This article is part of the Research Topic, https://doi.org/10.3389/fpubh.2022.989111, https://www.frontiersin.org/articles/10.3389/fpubh.2022.989111/full#supplementary-material, Creative Commons Attribution License (CC BY).

No. One peritoneal mesothelioma was reported in both studies (the same individual) and analyses including this case in the category of gastric cancers found no excess risk overall or by specific age categories (44, 45). Based on 130,154 total person-years of follow-up across five cohorts, the authors estimated that the pooled cohorts (30, 51, 53, 56) had 59% and 78% power to detect a 2.5-fold or greater and a 3.0-fold or greater increased risk of mesothelioma, respectively. (43) extended follow-up of this cohort from 1948 through 1989, reporting two deaths from pleural mesothelioma; however, the underlying causes of death on the death certificates officially were coded by the New York State nosologists as benign neoplasm of the respiratory system and malignant neoplasm of bronchus and lung, unspecified, respectively. What information will I receive following a Test of Abstract Language Comprehension? Cause-specific mortality and cancer morbidity in 390 male workers exposed to high purity talc: A six-decade follow-up. The Cosmetic Ingredient Review Expert Panel (Panel) assessed the safety of talc for use in cosmetics. (2003) 44:639. The results indicate that the talc industry exerted considerable influence over three key areas: regulatory proceedings at the FDA; testing methods and the manipulation of test results (including undisclosed results); and press coverage and the medical literature.

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). (2016) 38:e2016039. Epidemiological studies were selected to include groups exposed to talc, including talc miners and millers (the groups historically most highly exposed) as well as groups potentially exposed to cosmetic talcum powders and other products containing talc. doi: 10.1016/0041-008X(87)90284-5, 27. Web6.2 Exposure assessment. EPA. Improving the Presumptive Disability Decision-Making Process for Veterans. Talc deposition and effects after 20 days of repeated inhalation exposure of rats and mice to talc.

Integrating all streams of evidence according to the IOM framework yielded classifications of suggestive evidence of no association between inhaled talc and lung cancer and pleural mesothelioma at human-relevant exposure levels. Overall, the mechanistic evidence is insufficient to support an MOA whereby talc induces pulmonary carcinogenesis. (2007) 29:75760. doi: 10.1016/j.yrtph.2017.12.005, 58. Sept., 1990. Chem Biol Interact. WebFinal Screening Assessment for Talc (Mg3H2(SiO3)4) (published on April 22, 2021). Most of the available studies that evaluated lung cancers were rated medium quality. Further, some aspects of the physiology and function of the respiratory system of rodents (e.g., a delicate balance of pulmonary surfactants, as well as smaller and fewer macrophages relative to humans) make them highly susceptible to high doses of solid particles relative to humans (29). Food Cosmet Tox. 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). In animal studies, a statistically significant increase in lung tumors was observed after inhalation of talc, although these tumors were limited to females of one species. (46) reported one mesothelioma (site not specified) in an electrician hired at the plant 15 years prior to his death [possibly the same case reported in (42)]. doi: 10.1080/08958378.2020.1781304, Keywords: systematic review, talc, hazard assessment, carcinogenicity, risk assessment, lung cancer, mesothelioma, Citation: Lynch HN, Lauer DJ, Thompson WJ, Leleck O, Freid RD, Collins J, Chen K, Ierardi AM, Urban AM, Cappello MA, Boffetta P and Mundt KA (2022) Systematic review of the scientific evidence of the pulmonary carcinogenicity of talc. 0000006564 00000 n 0000008348 00000 n 389-92.
