Management of Potential Conflicts of Interest

IARC is committed to ensuring and demonstrating the independence of all its research studies from the influence of vested interests. In this regard, IARC considers several questions in relation to potential conflicts of interest for all studies: do they exist, have they been declared, should they be publicly disclosed, and are they actionable?

For this study, IARC is collaborating with the Federal State Budgetary Scientific Institution (FSBSI) Izmerov Research Institute of Occupational Health (RIOH) and the Yekaterinburg Medical Research Center for Prophylaxis and Health Protection in Industrial Workers. These institutes are partially government-funded and are tasked with conducting research into occupational risk factors and diseases as well as providing clinical care to workers. Employees of RIOH are recognized within Russia as leading experts on chrysotile and as such are called upon by the Ministry of Health to present their data and to provide technical guidance and recommendations based on their expertise. They are also required to represent the Russian government at various international meetings and forums. IARC is aware that some of the Russian study collaborators support and promote controlled use of chrysotile. IARC does not support this position.

All individual researchers of the study team (see below) have declared any potential conflicts of interest by completing the IARC Declaration of Interests forms (click here to see the IARC Declaration of Interest form), which are updated annually; in addition, conflicts of interest are made public in connection with every publication from the study, as for instance in (1).

In summary, IARC recognizes that conflicts of interest exist, has disclosed them, and considers that the potential consequences are addressed through the measures implemented in the study design and its conduct (see Study Team and Oversight) and that sound scientific results can be obtained.

IARC remains committed to providing the most reliable, independent scientific evidence on which public health decisions can be based. IARC and WHO have released a joint statement that this study will supply important scientific information to better quantify the risk of cancers already known to be related to chrysotile as well as additional cancers suspected to be related to chrysotile (see Joint WHO-IARC Statement).
