Title Systemic and CNS Activity of Selective RET Inhibition With Selpercatinib (LOXO-292) in a Patient With RET-Mutant Medullary Thyroid Cancer With Extensive CNS Metastases.
Abstract Text


  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
  • Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")


  • Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.

RET M918T thyroid gland medullary carcinoma sensitive Cabozantinib Case Reports/Case Series Actionable In a clinical case study, Cometriq (cabozantinib) treatment resulted in a partial response in a patient with medullary thyroid carcinoma with extensive CNS metastasis harboring MET M918T, although the patient experienced multiple adverse effects and her disease progressed after 8 months of treatment (PMID: 33154983). 33154983
RET M918T thyroid gland medullary carcinoma sensitive Selpercatinib Case Reports/Case Series Actionable In a clinical case study, Retevmo (selpercatinib) treatment resulted in rapid clinical improvement and complete resolution of the brain metastasis in a patient with metastatic medullary thyroid carcinoma harboring RET M918T whose disease progressed on prior Cometriq (cabozantinib) treatment, an official partial extracranial response was achieved at 1 year of treatment, until disease progression at 17 months (PMID: 33154983). 33154983
