Chemotherapy and Radiation Therapy Plus Bone Marrow or Peripheral Stem Cell Transplantation in Treating Patients With Relapsed or Refractory T-cell Lymphoma, Hodgkin's Lymphoma, or Non-Hodgkin's Lymphoma

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage cancer cells. Bone marrow or peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and radiation therapy and kill more cancer cells.

PURPOSE: Phase I/II trial to study the effectiveness of chemotherapy and radiation therapy plus bone marrow or peripheral stem cell transplantation in treating patients who have refractory or relapsed T-cell lymphoma, Hodgkin's lymphoma, or non-Hodgkin's lymphoma.

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.
