Abstract Text High-throughput analyses have revealed the presence of activating mutations in the AKT1 gene in a subpopulation of meningiomas. We report a female patient with multiple intracranial tumor manifestations and histologically verified meningotheliomatous meningioma in the lung. The tumor was continuously growing at multiple sites despite six surgical resections, radiotherapy, and two lines of systemic therapy. Following detection of an AKT1E17K mutation in three independent tumor samples by sequencing, treatment with AZD5363, a selective AKT inhibitor, was initiated. Ex vivo cultured meningioma cells exhibited sensitivity to the drug as shown by pAKT accumulation on immunoblots. Treatment with AZD5363 resulted, for the first time, in stable disease and minor radiographic response. The patient has been on that treatment for more than one year with ongoing clinical and radiographic response. This is the first report of an AKT1-mutant meningioma responding to AKT inhibition, suggesting that molecular screening may result in clinical benefit.

Filtering

  • 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"

Sorting

  • 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.
