Trial Information

Biomarkers and Dysplastic Respiratory Epithelium



- 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


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

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.

Inclusion Criteria


- Meets any of the following criteria:

- Diagnosis of extensive and severe dysplasia of the respiratory epithelium

- Recruited from the SPORE Tissue Procurement Screening Project or by private
or academic physicians (for patients with moderate or severe dysplasia)

- Survived 1 or more aerodigestive system carcinoma for ≥ 1 year

- Completely resected stage I non-small cell cancer

- Undergoing any of the following procedures:

- Routine panendoscopy for patients with head and neck cancer

- 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

- 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.

- Well-controlled atrial fibrillation or rare (< 2/min) premature ventricular
contractions allowed

- No ventricular tachycardia or supraventricular tachycardia with a rapid ventricular

- No other serious medical condition that would preclude a patient from undergoing a

- 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
