A pilot study of chlophepp-B—A weekly regimen for patients with untreated advanced or recurrent hodgkin's disease

Twenty-five patients with either previously untreated advanced Hodgkin's disease (HD) or with relapsed disease were treated with an intensive weekly chemotherapy regimen (ChlOPhEPP-B) in which the myelo-suppressive combinations of epirubicin and chlorambucil, and procarbazine and etoposide alternated at two-week intervals, interspersed with vincristine and prednisolone and then vincristine, prednisolone and bleomycin in a four-week cycle. Of the previously untreated patients (n=14), 12 (86 per cent) showed a complete response (CR); in the previously treated patients (n=11), CR was achieved in five (46 per cent). Toxicity was predictable and not evidently more severe than with more standard regimens. Neutropenia leading to treatment delay and/or dose reduction was seen in 11 patients (44 per cent) but severe neutropenia (WHO grade 4) was documented in only six patients (24 per cent) for a cumulative total of nine treatment weeks (1-8 per cent of the total treatment time). Dose reductions for neutropenia were applied in relation to 11 of the 379 weekly treatment points (2·9 per cent). Delays in treatment, for any reason, averaged 3·65 weeks per patient. The study demonstrated the feasibility of a more intensive weekly multidrug schedule. This approach may be applicable in the treatment of advanced HD and represents a further option in the strategy of treating relapsed disease.
