Abstract Text The addition of targeted agents to thoracic radiation has not improved outcomes in patients with locally advanced non-small-cell lung cancer (NSCLC). To improve cure rates in locally advanced NSCLC, effective targeted therapies need to be identified that can be given safely with radiation therapy. Temsirolimus is an inhibitor of the mammalian target of rapamycin (mTOR) pathway and has single-agent activity in lung cancer. Inhibition of the mTOR pathway has been found to augment the cytotoxic effect of radiation in preclinical studies. There is scant clinical experience with mTOR inhibitors and radiation.This was a phase I study evaluating the combination of temsirolimus with thoracic radiation in patients with NSCLC.Ten patients were enrolled in the study. The dose-limiting toxicities included sudden death, pneumonitis, and pulmonary hemorrhage. The maximum tolerated dose of temsirolimus that could be administered safely with concurrent radiotherapy (35 Gy in 14 daily fractions) was 15 mg intravenously weekly. Of the 8 evaluable patients, 3 had a partial response and 2 had stable disease.The combination of temsirolimus 15 mg weekly and thoracic radiation is well tolerated and warrants further investigation, perhaps in a molecularly defined subset of patients.

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (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 a longer phrase which contains spaces "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.
