Hodgkins Disease Study

OBJECTIVES:

• Establish a uniform practice for the management of children with Hodgkin's lymphoma.
• Document the long-term side effects of such management.
• Establish whether or not children can be safely managed without staging laparotomy and splenectomy.
• Establish whether or not chlorambucil, vinblastine, procarbazine hydrochloride, and prednisolone (CLVPP) is an effective alternative to mechlorethamine, vincristine, procarbazine hydrochloride, and prednisone (MOPP) chemotherapy.

OUTLINE: This is a multicenter study. Patients are assigned to 1 of 3 treatment regimens according to disease stage and presence of bulky mediastinal disease.

• Involved-field radiotherapy (for patients with stage IA [nodal] disease): Patients undergo involved-field radiotherapy 5 days a week for 4 weeks.
• CLVPP chemotherapy (for patients with all other stages of disease AND no bulky mediastinal disease): Patients receive CLVPP chemotherapy comprising oral chlorambucil, oral procarbazine hydrochloride, and oral prednisolone on days 1-14 and vinblastine IV on days 1 and 8. Treatment repeats every 28 days for up to 8 courses in the absence of disease progression or unacceptable toxicity.
• CLVPP chemotherapy and radiotherapy (for patients with all other stages of disease AND bulky mediastinal disease): Patients receive CLVPP chemotherapy as above. Patients then undergo radiotherapy to the mediastinum beginning 2 weeks after completing the last course of CLVPP chemotherapy.

After completion of study treatment, patients are followed periodically.
