Filgrastim and Chemotherapy Followed by Peripheral Stem Cell Transplant in Treating Patients With Hodgkin's Lymphoma or Non-Hodgkin's Lymphoma

OBJECTIVES:

- Assess the clinical outcomes, survival, and morbidity of transplantation in patients
with Hodgkin's lymphoma or non-Hodgkin's lymphoma when treated with filgrastim (G-CSF)
followed by high dose chemotherapy plus G-CSF followed by autologous peripheral blood
stem cell (PBSC) transplantation.

- Determine whether sufficient PBSC can be collected for use in autologous transplantation
in these patients when mobilized with hematopoietic growth factor alone compared to
chemotherapy plus growth factor.

- Determine whether these primed PBSC support prompt lymphoid and myeloid hematopoietic
recovery after transplantation in these patients.

- Compare the numbers of committed progenitor cells and/or primitive, pluripotential
hematopoietic stem cells with these two priming techniques.

- Compare the numbers of tumor cells in cryopreserved PBSC following these priming
techniques.

- Evaluate response and extended relapse free survival in conjunction with rapid
hematopoietic reconstitution and limited transplant associated morbidity and mortality
in these patients when treated with these regimens.

OUTLINE: In the first priming phase, patients receive filgrastim (G-CSF) subcutaneously (SQ)
daily on days 1-7 and peripheral blood stem cells are collected on days 6-8.

At least 48 hours after the last dose of G-CSF and after the third leukapheresis, patients
receive the second priming, which consists of cyclophosphamide IV over 2 hours on day 1 and
cytarabine IV over 1 hour every 12 hours for a total of 2 doses on day 1. Patients also
receive mitoxantrone IV over 1 hour daily and dexamethasone IV every 12 hours for a total of
4 doses on days 1-2. Patients receive G-CSF SQ daily beginning on day 4 and continuing until
the completion of leukapheresis. PBSC are collected on 3 consecutive days after blood counts
recover.

In the transplant phase, patients with non-Hodgkin's lymphoma who have not exceeded
pretransplant radiotherapy limits receive cyclophosphamide IV over 2 hours on days -7 and -6
and total body irradiation twice daily on days -4 through -1. Autologous PBSC are reinfused
on day 0. Patients receive G-CSF IV daily beginning on day 0 and continuing until day 21 or
until blood counts recover.

Patients with Hodgkin's lymphoma or patients with non-Hodgkin's lymphoma who have exceeded
pretransplant radiotherapy limits receive cyclophosphamide IV over 2 hours daily on days -6
through -3, carmustine IV over 1 hour on day -6, and etoposide IV over 4 hours every 12 hours
for a total of 6 doses on days -6 through -4. Autologous PBSC are reinfused on day 0.
Patients also receive G-CSF IV daily beginning on day 0 and continuing until day 21 or until
blood counts recover.

All patients receive radiotherapy for any residual nodal masses measuring at least 2 cm 5
days a week beginning on day 28.

Patients are followed at day 100, then every 3 months for 1 year, then every 6 months for 2
years, and then annually thereafter.

This was changed to a treatment guideline study.

DISEASE CHARACTERISTICS:

- Immunoblastic or small noncleaved cell lymphoma (Burkitt's or non-Burkitt's)
in complete or partial remission after initial therapy

- Localized (stage I or Zeigler stage A) small noncleaved (Burkitt's or
non-Burkitt's) after relapse or incomplete response to initial therapy

- Lymphoblastic lymphoma in second or greater complete or partial response

- High risk lymphoblastic lymphoma in first complete remission or after
initial therapy (high risk factors include stage IV disease, LDH greater
than 2 times normal, and 2 or more extranodal sites)

- Intermediate grade non-Hodgkin's lymphoma:

- Diffuse large cell lymphoma

- Diffuse mixed cell lymphoma

- Diffuse small cleaved cell lymphoma

- Follicular large cell lymphoma

- In second or greater complete or partial remission OR

- High risk in first complete remission or after initial therapy

- High risk features include:

- No complete response after 12 weeks of initial combination
chemotherapy

- Bulky disease (greater than 10 cm nodal masses or mediastinal
disease involving greater than 1/3 of the chest diameter

- Malignant pleural effusion

- Liver involvement

- LDH greater than 2 times upper limit of normal at diagnosis

- At least 2 extranodal sites

- Low grade non-Hodgkin's lymphoma:

- Follicular small cleaved cell lymphoma

- Follicular mixed cell lymphoma

- Diffuse small lymphocytic lymphoma

- In first or greater complete response OR

- Following initial treatment if complete response is not achieved

- In second or greater complete or partial response if treated at diagnosis
without clinical symptoms necessitating treatment

- T-cell lymphoma (nonlymphoblastic, intermediate, or high grade lymphomas) after
initial therapy whether or not complete response is achieved

- Hodgkin's lymphoma

- Stage I and II disease treated with primary radiotherapy and failure of at
least one combination chemotherapy regimen

- Stage III and IV disease with failure on mechlorethamine, vincristine,
procarbazine, and prednisone (MOPP)-like regimen, alternative noncross
resistant regimen (e.g., doxorubicin, bleomycin, vinblastine, and
dacarbazine [ABVD]), or a combination (e.g., MOPP-ABV)

- High risk features allowed including:

- Failure to achieve initial complete remission with MOPP and/or ABVD and
crossover or hybrid therapy

- Relapse within 6 months after initial therapy

- Relapse after initial radiotherapy with complete response longer than 1
year since initial therapy and subsequent failure on MOPP and/or ABVD
or hybrid

- Bulky mediastinal disease after initial therapy and residual mass of at
least 5 cm with other features of persisting disease (e.g., Gallium scan
positive, high LDH, enlarging on serial x-rays, or positive biopsy)

- No HIV or HTLV-1 associated lymphomas

- No resistant or refractory lymphoma (no partial response following up to 3 courses of
combination chemotherapy)

- No active ischemic or degenerative CNS disease NOTE: A new classification scheme for
adult non-Hodgkin's lymphoma has been adopted by PDQ. The terminology of "indolent" or
"aggressive" lymphoma will replace the former terminology of "low", "intermediate", or
"high" grade lymphoma. However, this protocol uses the former terminology.
