While this does not affect the quality of the study, as discussed below, micronized talc is not used in cosmetic talcum powder products and may limit the study's generalizability for assessing risk associated with the use of cosmetic talcum powder.

Using a lower-tier assessment approach, a small margin of exposure (MOE) of 1.5 was obtained through the comparison of the NOAEC of 2 mg/m 3 to the average In male F344/N rats, there was an increased incidence of benign or malignant pheochromocytomas of the adrenal gland, commonly observed in rats (21).

ECHA. The impact of prior occupational exposure to respiratory carcinogens also was not considered in most studies. While some cohort mortality studies reported an association between occupational talc exposure and lung cancer mortality, additional epidemiological investigations reported no such association or attributed observed increased risks to potential confounding by cigarette smoking, as risks did not correlate with indicators of talc exposure (4347). 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.

The primary literature search for talc exposure and all cancers was performed in PubMed (in April; updated September 2021) and yielded a total of 716 publications.

A few studies reported excess lung cancer mortality, but lung cancer mortality risk did not increase with increasing talc exposure and the association potentially was confounded by smoking.

(1967) 14:6637. It also is worth noting that despite claims that some talcs and therefore some talcum powders contain trace amounts of asbestiform minerals, high occupational exposures leading to large excesses of pneumoconiosis deaths were not associated with increased mortality from lung cancer, and these studies consistently report no excess (in fact, no cases) of malignant pleural mesothelioma. doi: 10.1016/0007-0971(79)90054-8, 35.

Our systematic review methods adhere to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and incorporated aspects from the US Institute of Medicine (IOM) and several United States (US) Environmental Protection Agency (EPA) frameworks for systematic reviews. 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.

Stille WT, Tabershaw IR. 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.

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. (1987() 87:22234. 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.

Overall ratings of medium quality for 14 cohort studies primarily were driven by potential confounding/variable control (especially for lung cancer and cigarette smoking) and exposure assessment, including characterization of talc exposure (e.g., by job, exposure concentration level and duration). May, 2018. For animal toxicology and selected mechanistic studies, we followed the TSCA study quality evaluation framework (12, 13) and assigned relative numerical ranks to each of the outcomes (1, 2, and 3 corresponding to high, medium, and low) for each metric, then averaged the metric scores to arrive at an overall relative rating of high, medium, or low quality. One day after dosing, macrophage numbers were not significantly altered, but there were increases in polymorphonuclear leukocytes (PMNs), lactate dehydrogenase, and peroxidase, indicating cellular injury. The chemical name of talc is hydrated magnesium silicate. Our speech and language therapists provide a range of services for children with speech, language and communication needs. Beck et al.

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. We employed qualitative and hierarchical or tiered approaches to arrive at the overall study quality score, tailored to each study type and outcome. 0000002271 00000 n Kleinfeld M, Messite J, Zaki MH. 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.
