(43) was the only study to report a statistically significant excess risk of lung cancer (SMR = 2.32; 95% CI: 1.573.29). The authors observed increases in macrophage infiltration at 50 and 100 mg/m3 talc, but not at the lowest concentration of 5 mg/m3. According to information reported under section 71 A 37-year update on mortality patterns in an expanded cohort of Vermont talc miners and millers. CAS No. In contrast to the lack of excess lung cancer deaths among talc miners and millers, a strong and consistent association has been observed between occupational talc exposure and non-malignant respiratory disease (NMRD), including pneumoconiosis (30, 43, 49, 56).

I have just had a review of his statement and they are concerned about his TALC 2 results he scored level 2 and they have said he should be at level 4, They said They also concluded [t]here is limited evidence in experimental animals for the carcinogenicity of talc not containing asbestos or asbestiform fibers. This review is now 12 years old, and several studies and reviews on talc exposure and pulmonary cancer risk have been published since the 2010 IARC Monograph (1, 5, 6). doi: 10.1006/rtph.1996.1076, 15. 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). While many studies received high ratings for individual metrics such as study participation and outcome assessment, limitations in other metrics or domains precluded some studies from receiving a high overall rating.

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). Lung cancer mortality was slightly elevated, but did not achieve statistical significance, in the French (SMR = 1.23; 95% CI: 0.761.89) and Vermont (SMR = 1.44; 95% CI: 0.982.03) talc miners and millers but was close to unity for the Austrian (SMR = 1.06; 95% CI: 0.432.19), Italian (SMR = 1.02; 95% CI: 0.821.27) and Norwegian (SIR = 1.17; 95% CI: 0.731.79) talc miners and millers (1, 30, 53, 56). Risk Science Institute ILSI. 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). Sept., 1993. Cause-specific mortality and cancer morbidity in 390 male workers exposed to high purity talc: A six-decade follow-up. 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). 37. Am J Ind Med. Although the paucity of mechanistic information remains a limitation, the balance of evidence, especially the volume of epidemiological evidence demonstrating no increased cancer risks associated with even the highest real world human-relevant exposures, strengthens the current analysis. HETA 90-390-2065/MHETA 86-012-2065. (1995) 21:2449. 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. 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). Long-term follow-up of thoracoscopic talc pleurodesis for primary spontaneous pneumothorax. Int J Tox. 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. The Chemical Abstracts Service Registry Number (CAS RN1) for talc is 14807-96-6. Wagner et al. Among 705 white men employed between 1957 and 1977, lung cancer mortality was statistically significantly elevated among workers employed < 1 year (SMR = 3.17, based on six lung cancer deaths). A three-fold excess of mortality due to NMRD was reported in the earliest cohort study of New York talc workers, reflecting the high concentrations of dust present in the workplace; prior to 1948, median exposures ranged from 61 to 1,196 mppcf (45). Full quality evaluation results are presented in Supplementary Table 2. 0000070271 00000 n (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. Regulatory toxicology and pharmacology : RTP, Abstract This study characterizes airborne asbestos exposures resulting from the adult application of cosmetic talc body powders spiked with known concentrations of tremolite.
