OBJECTIVES:
* Determine the toxicity of an intensive program of chemoradiotherapy followed by HLA identical related bone marrow or peripheral blood stem cell transplantation in patients with relapsed or refractory cutaneous T-cell lymphoma, Hodgkin's lymphoma, or non-Hodgkin's lymphoma.
* Determine the response rate and disease free survival in patients treated with this regimen.
OUTLINE: HLA identical related donors undergo harvest of bone marrow or peripheral blood stem cells (PBSC).
Patients are assigned to one of two treatment groups based on prior radiation to abdomen or mediastinum:
* Group A (prior radiation no greater than 2,000 cGy): Patients with complete response (CR) or partial response (PR) after completion of chemotherapy receive cyclophosphamide IV over 1 hour on days -6 and -5, followed by total body irradiation twice daily on days -4 to -1. Patients with minimal response after completion of chemotherapy receive cyclophosphamide IV over 1 hour on days -8 and -7, followed by etoposide IV over 30 hours beginning on day -6, followed by total body irradiation twice daily on days -4 to -1.
* Group B (prior radiation greater than 2,000 cGy): Patients with CR or PR after completion of chemotherapy receive oral busulfan every 6 hours on days -7 to -4, followed by cyclophosphamide IV over 1 hour on days -3 and -2. Patients with minimal response after completion of chemotherapy receive oral busulfan every 6 hours on days -9 to -6, followed by cyclophosphamide IV over 1 hour on days -5 and -4, followed by etoposide IV over 30 hours beginning on day -3.
* Both groups: Bone marrow or PBSC are reinfused on day 0. Patients with bulky nodal disease (greater than 5 cm) may undergo involved field radiotherapy two weeks before transplantation.
Patients are followed every month for 1 year.
