[Low-dose accelerated hyperfractionated radiotherapy for local control of chemoresistant Hodgkin's disease (a...

The results are evaluated of the combined treatment of 154 patients with relapsed refractory Hodgkin's disease, which was conducted using standard dosage of conventional chemotherapy. Out of those, 117 with residual lesions were randomized to receive either focal radiotherapy (20-24 Gy) in accelerated hyperfractionation (1.3-1.5 Gy, twice a day, at 5-hr interval) or 38-40 Gy in standard fractionation. Local control persisted in 85-97% of irradiated sites (median follow-up of 24 months), irrespective of irradiation technique. TTD being lowered down to 20-24 Gy due to use of accelerated hyperfractionation, the frequency of late-onset radiation injuries of paramediastinal lung tissue was lower than in standard treatment, with a subsequently lower fraction of patients with stage II fibrosis.
