Study summary

RYTHMIC (Réseau tumeurs THYMiques et Cancer) is a French nationwide network for TET with the objective of territorial coverage by regional expert centers and systematic discussion of patients management at national tumor board.

Read the detailed description

RYTHMIC (Réseau tumeurs THYMiques et Cancer) is a nationwide network for TET appointed in 2012 by the French National Cancer Institute. The objectives of the network are management of clinical tumor boards and central pathologic review of all cases. RYTHMIC Tumor Board is based on initial histopathological diagnosis.

RYTHMIC is a comprehensive tool for research:

  • to improve the management of patients
  • to monitor dedicated actions
  • to screen patients for future translational and clinical trials
