The aim of this study was to audit the results of a high-dose, combined-modality prospective protocol for non-small-cell lung cancer in terms of survival, disease-specific survival and toxicity. One hundred and twenty-one patients with non-small-cell lung cancer were treated with a concurrent, end-phase, boost, high-dose radiotherapy protocol with 65 Gy in 35 fractions for more than 5 weeks. Sixty-six patients received radiotherapy alone (group 1), 29 received concurrent chemoradiation (group 2) and 26 received neoadjuvant and concurrent chemotherapy (group 3). Thirty-four patients had stage I disease, six had stage II and 81 had stage III. Overall median survival was 23 months: 75% at 1 year and 23% at 5 years. Median survivals for patients with stage I and stages II and III disease were 43 and 19 months, respectively. For stages II and III patients by groups 1–3, median survivals were 18, 25 and 18 months, respectively, and 2-year survivals were 36, 52 and 38%, respectively. Toxicity was acceptable. Overall, 9% had symptomatic pneumonitis and 7% had grades 3 and 4 oesophagitis. For those who had the mediastinum included in the volume, grade ≥3 oesophagitis occurred in 0, 11 and 22% (n = 110, P = 0.001), respectively, for treatment groups 1–3. Overall treatment-related mortality was 3%, consisting of two septic deaths, one pneumonitis and possibly one late cardiac event, all occurring in patients who had chemotherapy (7% of 55 patients). Treatment-related mortality declined over the study period. Accelerated radiotherapy was well tolerated, with only moderate increased acute toxicity when combined with concurrent platinum chemotherapy. Toxicity was enhanced by induction chemotherapy. Overall survival outcomes were excellent for this condition. Continued use of this radiotherapy schedule is recommended as the platform for assessment of other chemotherapy schedules.
