The increased risk appeared to be limited to workers hired before 1955 (SMR pre-1955: 2.86; 95% CI: 1.904.14), as the SMR for workers hired after 1955 was 0.83 (95% CI: 0.172.42). Brown et al. 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). xA 04Fw\GczC. There was no evidence of carcinogenic activity of talc in male or female B6C3F1 mice. p. 379-88. 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. Web6.2 Exposure assessment. Sept., 1990. 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). The body of epidemiological literature evaluating talc exposure and risk of malignant mesothelioma, which consists of highly exposed workers with long follow up periods, fails to demonstrate any increased risk of malignant mesothelioma. Analysis of evidence: HL, DL, OL, RF, AI, WT, JC, AU, and KC.

All three studies provided explicit descriptions of talc aerosolization with exposure consistently administered across both control and experimental groups (except for some fluctuations in the NTP study). Tiering approach used in evaluating cohort studies. Int J Tox. 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. A few studies provide evidence of some key events in the proposed inflammatory MOA; however, data are limited to non-human relevant exposure pathways and/or cell-based assays. The questions follow Blanks language scheme (1978). Published in International journal of toxicology 2015, Monice M. Fiume, I. Boyer, +9 authors F. A. Andersen. Talc is a hydrous magnesium sheet silicate (Mg3Si4O10(OH)2) with particles that are plate-like in structure. 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. No statistical tests were reported in either publication. (2020) 63:4849. Bronchioalveolar lavage (BAL) fluid was collected and assessed at 1 day post exposure (all doses) or 1, 4, 7, and 14 days after talc administration (3.75 mg/100 g). None of the 17 cohort studies identified an increased risk of malignant pleural or peritoneal mesothelioma among talc miners and millers. Berlin: Springer-Verlag (1990). doi: 10.1093/oxfordjournals.aje.a114913. (2000) 12:117. All studies were screened and evaluated by two independent reviewers, and any discrepancies discussed and resolved. The chemical name of talc is hydrated magnesium silicate. It has been concluded that there was an inadequate evidence of carcinogenicity in experimental animals and the degree of evidence in short-term tests for genetic activity has been found to be inadequate. Features. p. 35763. However, considering several newer studies, combined with a more rigorous systematic review methodology, our evaluation differed from these, indicating suggestive evidence of no association. Malignant mesothelioma following repeated exposures to cosmetic talc: a case series of 75 patients. 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. This approval level enables you to buy all our assessments. 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). (56) reported that the death certificate for the single mesothelioma death in the cohort explicitly mentioned exposure to asbestos; yet no additional information was available regarding this potential exposure (56). Narrower age bands at younger age groups were used to reflect rapid changes in grammatical understanding and reliability and validity studies were conducted.

Exposures to talcum powder, tobacco, alcohol, and coffee. 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. Talc was administered to both species for 6 h per day, 5 days per week, for a total of 20 exposure days at talc concentrations of 0, 2, 6, or 18 mg/m3. 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. (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)].

(50) followed 1,346 talc miners and 438 millers hired between 1921 and 1950 and that worked for at least 1 year in the Val Chisone talc operations. Long-term follow-up of thoracoscopic talc pleurodesis for primary spontaneous pneumothorax. These workers were clearly and highly exposed to the talcs: all except the Norwegian cohort reported statistically significant excess mortality due to pneumonoconiosis, a group of non-malignant respiratory diseases caused by heavy exposure to dusts. Considering the totality of the evidence, we conclude that there is suggestive evidence of no association between inhaled talc and lung cancer at human-relevant exposure levels. %PDF-1.4
