6th ESTP International Expert Workshop, Berlin, Germany, May 16 – 17, 2018
Adversity of Thyroid Follicular Cell Hypertrophy/Hyperplasia

Dear Colleagues,

The 6th ESTP International Expert workshop will elaborate criteria for pathologists to assess adversity of thyroid follicular epithelial hypertrophy/hyperplasia, taking into account the differentiation between direct and indirect mechanisms and their implication for risk assessment.

Based on practical examples and expert contributions, it will be the goal of this workshop to:

  1. Summarize common mechanisms of thyroid follicular epithelial hypertrophy/hyperplasia and present example cases for direct and indirect modes of action
  2. Discuss adversity considerations for thyroid follicular epithelial hypertrophy/hyperplasia, species differences/human relevance, and implications for classification as endocrine disrupting compound
  3. Propose information requirements to support review and interpretation of thyroid follicular epithelial hypertrophy/hyperplasia with examples of information/testing strategies

After a series of preparatory teleconferences amongst experts, the face-to-face meeting of the 6th ESTP Expert workshop will take place at Bayer AG, Müllerstraße 178, 13353 Berlin (Germany), starting with a sandwich lunch on May 16, 2018, and lasting until May 17, 6.00 pm.

In addition to approximately 25 invited experts, including pathologists and toxicologists from international regulatory agencies, a limited audience (maximum: 40 persons) will be accepted to this expert discussion, which will comprise question & answer sessions. The list of experts and detailed schedule will be sent out approximately 6 weeks prior to the event.

The registration fee for this event includes lunch and coffee breaks on both days and will be 135 €.
