Brief Summary:

RATIONALE: Studying samples of sputum and tissue in the laboratory from patients with dysplasia or cancer and from normal volunteers may help doctors identify and learn more about biomarkers related to cancer. It may also help the study of cancer in the future.

PURPOSE: This laboratory study is looking at biomarkers in patients with respiratory tract dysplasia or lung cancer, head and neck cancer, or aerodigestive tract cancer and in normal volunteers.

Condition or disease Intervention/treatment
Esophageal Cancer Head and Neck Cancer Lung Cancer Precancerous Condition Other: immunohistochemistry staining method Other: laboratory biomarker analysis Other: sputum cytology Procedure: biopsy

Detailed Description:



  • Determine intermediate biomarkers of premalignant respiratory epithelial lesions, such as genetic mutations or altered growth factor expression, in patients with dysplasia of the respiratory epithelium or lung cancer, head and neck cancer, or aerodigestive tract cancer.


  • Establish a tissue repository of normal and dysplastic respiratory epithelium from endobronchial forceps and brush biopsy tissue from these patients and from normal volunteers.

OUTLINE: Patients are stratified according to presence of extensive and severe dysplasia of the respiratory epithelium (yes vs no).

Participants undergo sputum cytology, white-light (with or without fluorescence) bronchoscopy, and endobronchial biopsies. Participants also undergo endobronchial brushings and bronchial secretion collection and possibly bronchoalveolar lavage. Collected samples are processed by hematoxylin, eosin, and immunohistochemical staining and analyzed for specific biomarkers. Unused samples are stored in the tissue bank.

PROJECTED ACCRUAL: A total of 330 participants will be accrued for this study.

      • Resection of a bronchogenic carcinoma
      • Bronchoscopy for diagnosis or staging of suspected lung cancer
      • Subsequent bronchoscopy for surveillance or monitoring of response to endobronchial treatment in patients with prior high-grade dysplasia or worse
    • No dysplasia (normal volunteers)

      • No asthma
      • No lung disease
      • No respiratory illness within the past 2 weeks Patients suspected of or at risk for neoplastic lung disease who are undergoing a bronchoscopy in which differential diagnostic considerations may include multiple other etiologies such as infection and other processes.

  • No anginal
  • No clinically active coronary artery disease
  • No multifocal premature ventricular contractions
  • No poorly controlled congestive heart failure
  • No myocardial infarction within the past 6 weeks

  • No ventricular tachycardia or supraventricular tachycardia with a rapid ventricular response
  • No other serious medical condition that would preclude a patient from undergoing a bronchoscopy
  • No acute bronchitis or pneumonia within the past 8 weeks except when clinically proven as a possible result of lung cancer
  • No hypoxemia (i.e., < 90% saturation with supplemental oxygen) before bronchoscopy
