Studying Tumor Tissue Samples From Patients With Early-Stage Non-Small Cell Lung Cancer
Validation of Molecular Prognostic Tests in NSCLC

RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer.

PURPOSE: This research studies tumor tissue samples from patients with early- stage non-small cell lung cancer.

OBJECTIVES:

Primary

  • To develop and validate a clinically useful molecular prognostic signature based on RNA-expression arrays to accurately distinguish between good and poor outcome in patients with stage 1B non-small cell lung cancer (NSCLC) (T2aN0M0) by predicting the risk of cancer recurrence after surgery.

Secondary

  • To develop and validate a clinically useful prognostic signature for stage 1A NSCLC (T1a-bN0M0) that accurately predicts the risk of post-operative cancer recurrence and is part of a prognostic classifier, which also includes histological, pathological, and demographic parameters as in the primary objective.
  • To determine the effects on test accuracy of the histological subtype (adenocarcinoma [AC] vs squamous cell [SQA]) for each of the stage-specific prognostic classifiers.
  • To determine the relevant statistical features, including accuracy of predicting overall survival, cancer-specific survival, and disease-free survival at 3 and 5 years, for each of the prognostic classifiers validated.
  • To utilize the validated prognostic signatures and classifiers in stage 1B NSCLC to determine whether these can reliably predict good outcome among stage II NSCLC patients.

OUTLINE: This is a multicenter study.

RNA extracted from archived tumor tissue samples are analyzed for whole-genome expression profiling by Affymetrix Gene Profiling Array (cGMP U133 P2) and reverse transcriptase-polymerase chain reaction (RT-PCR). Results are then compared and validated with molecular prognostic signatures that already exist, patients demographics, clinical characteristics, treatment received, and outcomes. A new prognostic signature is then constructed and incorporated into combined classifiers.

DISEASE CHARACTERISTICS:

  • Patients must have been registered on CALGB-140202
  • The subject population to be studied in this protocol includes patients selected from CALGB-140202

    • Stage IA or IB non-small cell lung cancer
    • Preoperative chemotherapy or radiation-naïve patients' specimens only
    • Full annotation of histological (path report showing margins, histology, differentiation, lymphovascular invasion, etc.), demographic (age, smoking history, and gender), clinical (type of surgery in terms of extent of resection, peri-operative mortality), and follow-up information (recurrence, death, survival, additional chemotherapy/radiotherapy, and adjuvant therapy type and timing) will be required
  • All samples to be studied were obtained and stored as part of CALGB-140202; the material and data obtained from the patient's protocol record will be used to obtain appropriate clinical information; in no instance will the patient be contacted directly
  • Tumor specimens need to have 40% tumor content to be included
  • No specimens from patients who died during their peri-operative period (30 days or within same admission) from post-operative complications

PATIENT CHARACTERISTICS:

  • No known infectious disease, such as human immunodeficiency virus (HIV)
