BACKGROUND: The combination of 3 cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) and a tailored, extended irradiation schedule has been used to treat patients with early Hodgkin lymphoma (HL) in the authors' group since 1981. The randomized H97-E trial (1997-2004) was designed to assess the impact of a slightly reduced irradiation dose on the freedom from treatment failure (FFTF) rate.

METHODS: Patients with supradiaphragmatic HL at clinical stages I and II who had
RESULTS: The 10-year FFTF and overall survival rates were similar for the 89 patients in the EA (88.6% and 97.8%, respectively), for the 99 patients in the CA (92.6% and 95%, respectively), and for the 202 patients in the HCG (91.9% and 92.9%, respectively). Surprisingly, the 10-year incidence of severe or fatal complications was nil in the EA but reached 15.5% in the CA (P < .003) and 11.1% in the HCG.

CONCLUSIONS: Slightly lowering the radiation dose did not have an impact on the excellent cure rate among patients with early HL but significantly reduced the rate of long-term, radiation-induced complications.
