Summary
RATIONALE: Bortezomib and thalidomide may stop the growth of multiple myeloma by blocking blood flow to the cancer. Bortezomib may also stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving bortezomib together with thalidomide and dexamethasone may kill any cancer cells that remain after high-dose melphalan and stem cell transplant in patients with multiple myeloma.
PURPOSE: This phase II trial is studying the side effects of giving bortezomib together with thalidomide and dexamethasone after melphalan and stem cell transplant and to see how well it works in treating patients with stage I-III multiple myeloma.

Eligibility Criteria
Inclusion Criteria
- Multiple Myeloma patients with symptomatic disease, stage II or III at diagnosis or progressive stage I requiring chemotherapy and/or radiation therapy (by Salmon-Durie classification), who are not eligible for tandem transplant study using TMI; because of previous radiation or eligibility criteria; documentation of disease staging by both Salmon-Durie classification and International Staging System (ISS) is required
- Patients with non-secretory myeloma should have measurable serum free-light chain protein by the Free-lite test or measurable disease such as a soft tissue myeloma
- A minimum of 4 x 10^6 of CD 34 Positive cell/kg has been harvested
- A Karnofsky performance status (KPS) of >= 70% is required unless the KPS is impaired due to bone disease
- No contraindication to the collection of a minimum of 4 x 10^6 CD34+ cells/kg by apheresis
- All patients must have signed a voluntary, informed consent in accordance with institutional and federal guidelines
- Bilirubin = = 40cc/min
- Absolute neutrophil count of > 1000/ul
- Platelet count of > 100,000/ul
- Cardiac ejection fraction >= 45% by multigated acquisition (MUGA) scan and/or by echocardiogram
- Diffusing capacity of the lung for carbon monoxide (DLCO) >= 50% of predicted lower limit
- Human immunodeficiency virus (HIV) antibody tests negative
- No other medical, or psychosocial problems which in the opinion of the primary physician or principal investigator would place the patient at unacceptably high risk from this treatment regimen
Exclusion Criteria
- Presence of peripheral neuropathy >= grade II
- Patients with evidence of disease progression (with >= 25% increase in M protein) on bortezomib and or thalidomide therapy prior to transplant
- Pregnant or nursing women, as well as women of child bearing age, who are unwilling to use a dual method of contraception and men who are unwilling to use condom
- Patients with history of hypersensitivity to bortezomib, boron or mannitol
