Indication/Tumor Type head and neck squamous cell carcinoma
Response Type predicted - sensitive


  • 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")


  • 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.

PIK3CA E542K head and neck squamous cell carcinoma predicted - sensitive Alpelisib + Cetuximab + Radiotherapy Case Reports/Case Series Actionable In a Phase Ib trial, 11 of 11 patients with metastatic head and neck squamous cell carcinoma demonstrated no evidence of disease at 3 to 4 months following treatment with Piqray (alpelisb) in combination with Erbitux (cetuximab) and intensity modulated radiation therapy (IMRT), and PIK3CA E545K was identified in one patient with oropharyngeal squamous cell carcinoma who had a near complete radiologic response within 8 days of starting IMRT (PMID: 31678634). 31678634
