PURPOSE: Hypofractionated chest radiotherapy regimens have provided excellent palliation of pulmonary symptoms in patients with inoperable non-small-cell lung cancer (NSCLC) and poor performance status in studies from Asia and Europe. We conducted a prospective study of this approach in patients from the United States. METHODS AND MATERIALS: Twenty-three patients with symptomatic NSCLC and an Eastern Cooperative Oncology Group performance status of > or =2 were enrolled between December 1994 and October 2001. Two "involved-field" fractions of 8.5 Gy were delivered 1 week apart. Patients were assessed for efficacy, toxicity, and tumor response at baseline, treatment completion, and 1 week, 1 month, and 4 months after completing radiotherapy. RESULTS: The median follow-up after treatment began was 4.3 months (range, 0.3-38). The median forced expiratory volume in 1 s and Eastern Cooperative Oncology Group performance status as measured at baseline was 1.05 L and 3, respectively. The most common presenting pulmonary symptoms were dyspnea (100%), cough (96%), anorexia/nausea (65%), and chest pain (52%). Between treatment completion and up to 4 months after treatment, dyspnea, cough, anorexia/nausea, chest pain, hoarseness, hemoptysis, and dysphagia had improved in 30%, 60%, 67%, 75%, 25%, 100%, and 100% of patients, respectively. No cases of treatment-related esophagitis, pneumonitis, or radiation myelopathy occurred. Progressive local disease was seen in only 1 (6%) of 18 assessable patients 4 months after treatment. CONCLUSION: For patients with poor performance status and inoperable NSCLC causing pulmonary symptoms, hypofractionated, involved-field radiotherapy, 8.5 Gy in two fractions, offers acceptable palliation with minimal toxicity. A clear advantage of the very short hypofractionated regimen is that it enables patients with a short expected survival time to spend more of their remaining time away from the hospital.
