early detection of second lung cancer in patients with stage i non-small cell lung cancer

Conditions: Lung Cancer

Summary: rationale: using new methods to examine sputum samples for the presence of cancer cells may detect lung cancer earlier. purpose: screening trial to study the effectiveness of new methods of examining sputum samples to detect second primary lung cancer in patients with resected stage i non-small cell lung cancer.

objectives: i. evaluate whether immunostaining of induced sputum specimens improves the sensitivity and specificity of routine morphologic sputum surveillance to detect second primary lung cancer in patients with previously resected nonsmall cell lung cancer. ii. evaluate which patients are at risk of developing a second primary lung cancer by immunostaining specimens from patients with no morphologic atypia on routine papanicolaou cytology. iii. make available archived sputum samples and bronchial washings for further analysis of new antibodies and techniques. iv. evaluate whether analysis of elevations of relevant growth factors in bronchial lavage fluid from patients with positive immunostaining or morphologic atypia increases the accuracy of early detection. v. evaluate whether quantitation of shed antigens in sputum increases the accuracy of early detection. vi. evaluate whether the extent of airway obstruction, as measured by the forced expiratory volume, can predict an increased risk of developing lung cancer. outline: screening for second primary lung cancer. annual sputum induction for papanicolaou cytology and immunostaining (using monoclonal antibodies 624h12 and 703d4), with optional pulmonary function tests and fiberoptic bronchoscopy with bronchial washings. projected accrual: 1,100 patients will be entered over 3 years. the sample size will be adjusted based on the rate of positive staining in the first 100 patients. patients followed at uncertified centers are analyzed separately.
