PurposeFeasibility and activity of concurrent hyperfractionated radiotherapy (Hfx RT) and low-dose, daily carboplatin and paclitaxel were investigated in patients with early-stage (I/II) non-small-cell lung cancer in a phase II study.Patients And MethodsFifty-six patients started their treatment on day 1 with 30 mg/m2 of paclitaxel. Hfx RT using 1.3 Gy bid to a total dose of 67.6 Gy and concurrent low-dose daily carboplatin 25 mg/m2 and paclitaxel 10 mg/m2, both given Mondays through Fridays during the RT course, started from the second day.ResultsThere were 29 complete responses (52%) and 15 partial responses (27%), and 12 patients (21%), experienced stable disease. The median survival time was 35 months, and 3- and 5-year survival rates were 50% and 36%, respectively. The median time to local progression has not been achieved, but 3- and 5-year local progression-free survival rates were 56% and 54%, respectively. The median time to distant metastasis has not been achieved, but 3- and 5- year distant metastasis-free survival rates were 61% and 61%, respectively. The median and 5-year cause-specific survivals were 39 months and 43%, respectively. Acute high-grade (> 3) toxicity was hematologic (22%), esophageal (7%), or bronchopulmonary (7%). No grade 5 toxicity was observed. Late high-grade toxicity was rarely observed (total, 10%).ConclusionHfx RT and concurrent low-dose daily carboplatin/paclitaxel was feasible with low toxicity and effective in patients with stage I/II non-small-cell lung cancer. It should continue to be investigated for this disease.
