Abstract:
121 Background: We evaluated the role of pre-treatment pulmonary function testing (PFT) in predicting the likelihood of cardiac and/or pulmonary toxicity for esophagus cancer patients receiving trimodality therapy. Methods: From 2007 to 2013, 64 patients with esophageal cancer received trimodality therapy at a single tertiary center with pre-treatment PFTs. The odds ratio of pre-treatment PFT as a predictor of cardiopulmonary toxicity was assess with univariate analysis (UVA). FEV1 (forced expiratory volume in 1 second) and DLCO (diffusion capacity for carbon monoxide) were assessed per 0.5-unit decrease. Percent FEV1 and DLCO predicted were assessed per 10% decrease. Results: The median age was 62 years (range, 41-79) with 88% male patients. A total of 70% of patients had adenocarcinoma with 66% having stage 3 disease. Most patients were former (43%) or current smokers (32%) and 18% had COPD. One or more cardiac comorbidities were observed in 54% of patients. The median RT dose was 50 Gy and the most frequent concurrent chemotherapy was cisplatin/5FU (53%). The median pre-treatment FEV1 and DLCO was 2.8 liters (range, 1-4.9) and 22.5 mL/min/mmHg (range, 17.2-25.5), respectively. This correlated to a median percent predicted value for FEV1 and DLCO of 85% (range, 30-124%) and 81.5% (range, 49-119%), respectively. The overall rate of any cardiac and pulmonary toxicity was 35% and 50%, respectively. Percent predicted value of both FEV1 and DLCO was statistically associated with pulmonary but not cardiac toxicity (Table). Conclusions: Patients with compromised pre-treatment pulmonary function are at higher risk of developing post-treatment pulmonary toxicities. Pulmonary function testing should be routinely performed prior to initiation of trimodality therapy for patient risk stratification. [Table: see text]
