Immune Reconstitution After Autologous Hematopoietic Stem Cell Transpl for High-Risk Lymphoma

OBJECTIVES:

Primary

- Assess immune reconstitution as measured by response to pneumococcal polyvalent vaccine,
NK-cell activity against autologous lymphoblastoid cell lines, and cytomegalovirus and
Epstein-Barr virus tetramer responses in patients who have undergone autologous
hematopoietic stem cell transplantation for high-risk lymphoma or multiple myeloma.

Secondary

- Assess the absolute number of circulating regulatory T-cells and the function of these
cells as measured by their expression of TGFβ and interleukin-10 (IL-10).

- Evaluate the effect of conditioning therapy on quality of life, including functional
status, fatigue, and depression, in these patients.

- Correlate quality of life with inflammatory cytokine production of peripheral blood
monocytes at specified time points.

- Provide baseline immune reconstitution and quality of life pilot data for comparison in
future post-transplant immunotherapy trials.

OUTLINE: Patients receive pneumococcal polyvalent vaccine intramuscularly once in weeks 9,
17, and 25 after autologous hematopoietic stem cell transplantation.

Blood samples are collected periodically for correlative and immunological studies.

Quality of life (QOL) is assessed periodically using the QOL short form (SF-36, 4-week
version), the Center for Epidemiologic Studies Depression scale (CES-D), and the
Multidimensional Fatigue Symptom Inventory (MFSI-30).

etoposide, cytarabine, and methotrexate (for high-risk lymphoma) as conditioning
therapy

PATIENT CHARACTERISTICS:

investigator(s) to likely interfere with the patient's ability to sign informed
consent, cooperate and participate in the study, or interfere with the interpretation
of the study results

PRIOR CONCURRENT THERAPY:
