National Toxicology Program; Hormonally-Induced Reproductive Tumors: Relevance of Rodent Bioassays Workshop

Resumen

For more than a quarter century, the National Toxicology Program (NTP) testing program has provided extensive and useful scientific information for predicting human health hazards and protecting public health. The NTP periodically conducts reviews of animal models used in its bioassays to critically analyze their predictive power and determine whether the protocols for these studies should be altered. As part of this effort, the NTP is convening a workshop titled "Hormonally-Induced Reproductive Tumors: Relevance of Rodent Bioassays." The 2\1/2\ day workshop will be held on May 22-24, 2006, at the Marriott Raleigh Crabtree Valley, 4500 Marriott Drive, Raleigh, NC 27612. The workshop's overall goal is to determine the adequacy and relevance to human disease outcome of rodent models for four types of hormonally-induced reproductive tumors (ovary, mammary gland, prostate, and testis). Other topics for discussion include proposed modes of action (for each tumor type and for hormonal tumors in general), dose response for tumor induction, predictiveness of rodent pre-neoplastic events for humans, the importance of the inclusion of an in utero exposure in the etiology of specific tumors,
