We developed a priori inclusion and exclusion criteria to identify the most relevant articles for full review consistent with systematic review principles. For each cohort, excluding the Austrian and French cohorts, mortality was updated at least once. Our conclusions regarding hazard for each cancer type, based on the IOM classification system (8), are described below and in the protocol, and visualized in Table 2. Exposure to talc aerosol produced no statistically significant differences in body weight; survival; or the type, incidence, or degree of histopathological change, relative to unexposed controls. Talc was also negative in a companion host-mediated mutagenicity assay using male ICR mice injected with Salmonella typhimurium and Saccharomyces cerevisiae, with and without metabolic activation (16). The assessment can be used with children from the age of 2+. 7. Additionally, the NTP (19) study involved the use of micronized talc, which has a smaller aerodynamic diameter than mined and milled talcs and talc used in talcum powder products. DHEW (NIOSH) Pub.

Washington, DC: U.S. Environmental Protection Agency (EPA)-Office of Chemical Safety and Pollution Prevention (2021). 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). The conclusions we reached in this systematic review are similar to those of IARC. 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. the objective of this paper was to apply systematic review methods to critically evaluate and synthesize the scientific evidence addressing the possible relationship (s) between exposure to talc occupationally and from exposure to talc-containing products (primarily talcum powders and cosmetics) and pulmonary cancers, specifically lung Visuospatial [Score 0-5] Updated 20/11/2012 .

Lawsuits Over Talc and Cancer Since 2014, Johnson & Johnson has defended its talcum powder in lawsuits brought by families of women who had used their talcum powder products and died from ovarian cancer. However, considering several newer studies, combined with a more rigorous systematic review methodology, our evaluation differed from these, indicating suggestive evidence of no association. doi: 10.1002/ajim.4700170408, 53. CAS No. In the time-course evaluation, most findings returned to control levels within 14 days. (1987() 87:22234. WebThe greatest ovarian cancer risk associated with perineal talc use was observed in the subgroup of women estimated to have made more than 10,000 applications during years when they were ovulating and had an intact genital tract (OR 2.8, 95% CI 1.4-5.4); however, this exposure was found in only 14% of the women with ovarian cancer. A nested case-control analysis showed no association of lung cancer with increasing cumulative exposure to talc, after adjusting for smoking, exposure to quartz, and underground work (30).

For pulmonary cancers, it is therefore plausible that talc could cause irritation and a cascade of inflammatory mechanisms. It has been reported that some cosmetic talcs and finished talcum powders may contain trace levels of asbestiform minerals despite the lack of evidence of reliably detectable asbestos at the major sources (1). There was a single occurrence of malignant mesothelioma in a high-dose male rat; however, aging F344 rats have been reported to develop spontaneous mesotheliomas (22). 18.

The authors reported issues with the consistency of administration of talc aerosol over some weeks in the middle of the study, likely resulting in increased talc exposure. Questions relate to the immediate environment and require the child to think concretely e.g. Six historical talcum powders were evaluated using modern-era analytical methods to determine if asbestos is present, and if so, to identify the mineral habit ( asbestiform versus non-asbestiform) of the asbestos.

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). Wagner et al. : 93-3152. 41. Based on the quality evaluation methods, domains and quality criteria (described above and detailed for all studies in Supplementary Tables 5, 6), most of the studies assessing pulmonary cancer risk among talc miners and millers were rated medium quality. Specifically, our findings for pulmonary cancers are consistent with IARC's classification of inhaled talc not containing asbestos or asbestiform fibers as not classifiable as to its carcinogenicity, in that neither identified any clear increase in cancer risk in animals and humans, and no clear MOA for carcinogenesis was identified (4). Table 2. An analysis of the National Toxicology Program's (NTP) technical report (NTP TR 421) on the toxicology and carcinogenesis studies of talc. 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. This assessment presents information relevant to the safety of talc as used in cosmetic formulations. Details regarding the cohorts and study methods can be found in Supplementary Tables 3, 4. Animals were exposed to 0, 6, or 18 mg/m3 talc for 6 h/day for 5 days/week until death or until the mortality of any exposure group reached 80% (approximately 2 years). 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. Similar findings were reported in rats exposed to non-asbestiform talcum powder for 6 h per day for 4 weeks via whole-body inhalation (28). Particle overload is common when high doses of poorly insoluble particles are administered particle clearance mechanisms of the lung are overwhelmed and carcinogenic processes are initiated (23, 24): see Mechanistic evidence and Mode of Action. There was no evidence of carcinogenicity in mice exposed to talc. WebWelcome to TALC - Teaching and Learning Consultation Skills.

(42) were employed <1 year (42). The objective of this paper was to apply systematic review methods to critically evaluate and synthesize the scientific evidence addressing the possible relationship(s) between exposure to talc occupationally and from exposure to talc-containing products (primarily talcum powders and cosmetics) and pulmonary cancers, specifically lung cancer and pleural mesothelioma, integrating epidemiology, toxicology, and studies informing potential underlying modes of action. There is no credible evidence of a cancer risk from inhalation of cosmetic talc by humans from retrospective epidemiological, statistically barely significant case-control studies of questionable biological import, and convincing scientific documentation is shown. EPA. 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. This can impact certain aspects of social and academic development. In order to increase cohort size, the New York cohorts did not limit eligibility based on minimum employment (e.g., 1 year) as is common in cohort mortality studies (42). Make basic level predications e.g. The evidence for possible carcinogenic mechanisms of talc is limited; however, a genotoxicity MOA confidently can be ruled out.

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).
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. Given the moderate confidence in study quality ratings and the lack of a consistent association between occupational talc exposure and lung cancer mortality, the available epidemiological evidence does not demonstrate a causal association between talc exposure and lung cancer mortality.
