Figure 9. DATA Framework for Second-line Therapy of RAIR DTC
DATA framework for treatment of patients with progression on (or intolerance to) first-line therapy
for RAIR metastatic DTC.
a
Biopsy of progressive disease when acquired resistance emerges is advised to evaluate for potentially
actionable resistant mechanisms.
b
If targeted therapy or clinical trial is not available, cabozantinib or another MKI may be considered
in patients treated with lenvatinib first-line.
