Abstract Text Anaplastic lymphoma kinase (ALK) fusion gene-positive lung cancer often shows brain metastasis at initial diagnosis or during the course of treatment. However, molecular-targeted drugs are known to pass through the blood-brain barrier and present positive effects for central nervous system lesions. There are few reports suggesting how effective molecular-targeted drug therapy alone is for brain metastasis lesions of ALK fusion-positive lung cancer, especially after the first use of ALK-tyrosine kinase inhibitor (TKI) or for bulky brain metastases. A patient in his mid-fifties with stage IV pleural dissemination developed brain metastases after 10 years of crizotinib use, but showed a complete response after switching to brigatinib. Moreover, a patient in her early sixties with stage III recurrent large brain metastases 5 years after chemoradiation therapy experienced dramatic tumor shrinkage with brigatinib. In each case of ALK fusion gene-positive lung cancer with brain metastases, brigatinib showed a high efficacy and was well-tolerated after previous ALK-TKI and for bulky lesions.

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.
