Hodgkin's disease with a mediastinal mass greater than 10 cm: Results of four different treatment approaches

Background: Management of Hodgkin's disease (HD) and large mediastinal adenopathy (LMA) usually includes intensive chemotherapy (CT) with or without radiation therapy (XT) regardless of stage. Patients and methods: One hundred and eighteen evaluable patients received one of four treatment regimens: (1) 6 cycles of MOPP or similar CT and XT; (2) 2 of MOPP followed by XT;(3) 6 of CVPP/ABDIC (cyclophosphamide, vincristine, procarbazine, prednisone/doxorubicin, bleomycin, decarbazine, prednisone, lomustine) followed by XT; or (4) 3 of NOVP (mitoxantrone, vincristine, vinblastine, procarbazine) and XT. XT doses included 30-40 Gy to areas of nodal involvement noted prior to therapy. Results: Complete remission (CR) rates for groups 1, 2, 3, and 4 were 100%, 85%, 87%, and 96%. Respective 3-year freedom from progression (FFP) results were 88%, 66%, 82%, and 88%, and 3-year freedom from tumor mortality (FTM) results were 100%, 84%, 84%, and 100%. The presence of B symptoms and stage IV disease was correlated with lower CR and 3-year FFP rates but similar 3-year survival. Conclusions: Results of this study suggest that patients with stage I-III Hodgkin's disease and LMA greater than 10 cm treated with 3 NOVP and XT have results similar to those obtained for a similar group of patients treated with 2 to 6 MOPP or 6 CVPP/ABDIC and XT. NOVP has also been reported to produce limited toxicity in this trial and should be considered as an alternative to MOPP or doxorubicin-containing regimens in treatment of patients with early-staged disease and LMA greater than 10 cm.
