Randomized Controlled Trial Clinical Trial
Hyperfractionated radiation therapy with and without concurrent chemotherapy for advanced non-small cell lung cancer.
Locally advanced non-small cell lung cancer (NSCLC) continues to be a frustrating challenge for oncologists. In this group of patients, the overall 5-year survival rates have been 3-6% in prospective randomized trials with radiation therapy (RT) alone. ⋯ The acute toxic effects observed during this study in treatment arms 1 and 2 are at least comparable to those previously published in other studies of this type, but a high incidence of acute overall toxic effects was observed in treatment arm 3. Regarding late toxic effects, the authors observed a higher incidence of Grade 3 overall late toxic effects in treatment arm 2 and a high incidence of Grade 4 overall late toxic effects in treatment arm 3. Results of this study show that the addition of CT to HFX RT carries a risk of increased high-grade toxic effects, both acute and late.
