Relevant Treatment Approaches

Filtering

  • 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")

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.

ROS1 fusion ROS1 L1951R ROS1 L2026M lung non-small cell carcinoma predicted - resistant Crizotinib Case Reports/Case Series Actionable In a clinical study, a non-small cell lung carcinoma patient harboring a ROS1 fusion progressed after 17 months of treatment with Xalkori (crizotinib), and was found to have acquired two additional mutations in trans, ROS1 L2026M and ROS1 L1951R, and cells derived from this patient showed partially decreased SHP2 and ERK1/2 signaling and ROS1 activation (PMID: 29636358). 29636358
ROS1 fusion ROS1 L1951R ROS1 L2026M lung non-small cell carcinoma resistant Ceritinib Case Reports/Case Series Actionable In a clinical study, a non-small cell lung carcinoma patient co-harboring a ROS1 fusion, and two other mutations in trans, ROS1 L2026M, and ROS1 L1951R demonstrated resistance to treatment with Zykadia (ceritinib), and cells derived from this patient showed partially decreased SHP2 and ERK1/2 signaling and ROS1 activation (PMID: 29636358). 29636358
