Abstract Text ALK-positive large-cell neuroendocrine carcinoma (LCNEC) is an exceptionally rare form of lung cancer. The efficacy of ALK inhibitors in treating ALK-positive LCNEC remains unclear. Here, we report a case of ALK-positive LCNEC of the lung, which revealed a sustained clinical benefit (24+ mo of overall survival) after treatment with sequential ALK inhibitors and local therapies. This remarkable improvement in survival underscores the importance of testing metastatic LCNEC for biomarkers, such as ALK rearrangement, using immunohistochemistry or next-generation sequencing, especially in younger patients.

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.
