Abstract Text We wanted to present a case with coexistence of anaplastic lymphoma kinase (ALK) and c-ros oncogene 1 (ROS1) rearrangements that has been in remission for a long time with crizotinib. A 62-year-old nonsmoker male patient was diagnosed with Non-small cell lung cancer. Progression developed 9 months after the treatment, and coexistence of ALK and ROS1 positivity were detected in driver mutation analysis performed with fluorescent in situ hybridization. Crizotinib 2 × 250 mg was started in November 2016. The treatment of the patient, who has been in remission for approximately 55 months since then, continues. Until recently, the use of next-generation sequencing (NGS) was not common, but the more frequent epidermal growth factor receptor, then ALK, and finally ROS1 mutation were studied in tumor tissues. Sometimes ROS1 was not studied because there was not enough tissue left. We think that this rate will increase a little more with the widespread use of NGS from now on. Showing that ALK and ROS1 are positive together, longer survivals can be obtained by choosing therapies that are responsive to both.

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.
