  Purpose

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.

PURPOSE: This research study is studying biomarkers in blood samples from patients with refractory non-small cell lung cancer previously treated with sorafenib tosylate.


Condition Intervention

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Mutation rate of sorafenib tosylate-target gene BRAF, and its upstream proteins KRAS and EGFR [ Designated as safety issue: No ]
  • Association between BRAF, KRAS, and EGFR mutation status and clinical benefits (stable disease or partial response) [ Designated as safety issue: No ]

Estimated Enrollment: 80
Study Start Date: June 2010
Estimated Primary Completion Date: July 2010 (Final data collection date for primary outcome measure)
Detailed Description:

OBJECTIVES:

  • To determine the mutation rates of BRAF, KRAS, and EGFR in patients with non-small cell lung cancer treated with sorafenib tosylate on protocol ECOG-2501.
  • To determine the association between BRAF, KRAS, or EGFR mutation status and clinical benefits in patients treated with this regimen.

OUTLINE: This is a multicenter study.

DNA is isolated from archived plasma samples and analyzed for BRAF, KRAS, and EGFR mutations.
