- Histologically confirmed Non-Small Cell Lung Cancer (NSCLC) of adenocarcinoma, squamous cell carcinoma, large cell carcinoma, or NSCLC not otherwise specified. Patients with suspected NSCLC may enroll prior to the diagnostic biopsy in order to obtain both the diagnostic and molecular analysis-required specimen during the same procedure. Must have blood work within 30 days prior to biopsy to eliminate any unnecessary biopsies on patients that do not qualify (screen failures) due to laboratory values that do not meet the inclusion/exclusion criteria. If a patient has blood work obtained at an outside facility, this can be utilized for the preliminary assessment prior to biopsy, but final inclusion/exclusion values must be obtained within 14 days of start of treatment.
