Relevant Treatment Approaches


  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (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 a longer phrase which contains spaces "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.

MAP2K1 P124L lymphatic system cancer predicted - sensitive Cobimetinib Case Reports/Case Series Actionable In a Phase II trial, treatment with Cotellic (cobimetinib) in patients with histiocytic neoplasms resulted in a PET overall response rate of 89% (16/18), with complete response in 72% (13/18) and partial response in 17% (3/18), and resulted in stable disease in 6% (1/18) of patients, including a complete response in a patient with mixed histiocytosis harboring MAP2K1 P124L (PMID: 30867592; NCT01953926). 30867592
