Abstract
7551 Purpose: To describe the effects of multimodality treatment on lung function in patients with stage III non-small cell carcinoma of the lung (NSCLC) Methods: Pulmonary function tests (PFTs) were reviewed for 32 patients with stage III NSCLC who were enrolled in a multimodality protocol that included neoadjuvant (NAd) combined chemoradiotherapy (taxol 50 mg/m2, carboplatin AUC 2 weekly X 3, radiation (XRT) 1.8 Gy BID to 30 Gy + erlotinib 150 mg/d for 28 days, followed by resection (R) and adjuvant (Ad) chemoradiotherapy (same as induction) followed by erlotinib 150mg/d maintenance (M) for 2 years. Changes in PFTs were analyzed at multiple time points (baseline to after NAd, after NAd to after R, after R to after Ad) and for the overall effect of treatment (baseline to the end of treatment). Results: The table below shows changes in percent predicted pulmonary function test values at each step in the treatment course. + signifies an increase and - a decrease. P indicates pneumonectomy and L lobectomy. Numbers in parentheses are the number of patients with complete testing at that time point. Conclusions: Neoadjuvant combined chemoradiotherapy has a small effect on lung function testing. The combined effect of multimodality therapy for stage III lung cancer that includes surgical resection leads to larger declines in lung function than have been reported historically for resection alone.
