RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die.
OBJECTIVES: I. Determine the rate of objective response and disease stabilization in patients with relapsed or refractory multiple myeloma treated with R115777. II. Determine whether the degree of inhibition of FTase activity and farnesylation of lamin-B, H-, K-, and N-RAS in peripheral blood mononuclear cells and tumor tissue correlates with tumor response in patients treated with this regimen. III. Determine whether the presence of activating RAS mutations in myeloma cells predicts treatment response in patients treated with this regimen. IV. Correlate R115777 plasma levels and RAS mutation status with tumor response in patients treated with this regimen.
OUTLINE: Patients receive oral R115777 twice daily on days 1-21. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity. Patients are followed for at least 30 days.
PROJECTED ACCRUAL: Approximately 12-42 patients will be accrued for this study within 25 months.
Primary Purpose: Treatment

RATIONALE: Tipifarnib and bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving tipifarnib together with bortezomib may kill more ca...
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of R115777 in t...
RATIONALE: Paricalcitol may cause multiple myeloma cells to look more like normal cells, and to grow and spread more slowly. Paricalcitol may also stop the growth of the cancer cells by bl...
The purpose of this study is to test the effect of the combination of bortezomib and tipifarnib. Bortezomib (VELCADE) is approved by the Food and Drug Administration (FDA) for the treatmen...
RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of celecoxib may be effective in preventing multiple myelo...
Multiple myeloma (MM) is a fatal and incurable hematological malignancy thus new therapy need to be developed. Cold atmospheric plasma, a new technology that could generate various active species, cou...
Multiple myeloma (MM) is a malignant plasma cell disease with a poor survival, characterized by the accumulation of myeloma cells (MMCs) within the bone marrow. Epigenetic modifications in MM are asso...
Multiple myeloma (MM) is a plasma cell neoplasm which constitutes about 10% of all hematologic malignancies. Despite the development and application of novel agents, MM still undergoes an aggressive a...
To estimate the association between organochlorine pesticides and polychlorinated biphenyls (PCBs) and multiple myeloma (MM).
Although epidemiologic studies have suggested a possible association between occupational exposures to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and the risk of development of multiple myeloma, defin...
An asymptomatic and slow-growing PLASMA CELL dyscrasia characterized by presence of MYELOMA PROTEINS and clonal bone marrow plasma cells without end-organ damage (e.g., renal impairment). It is distinguished from MONOCLONAL GAMMOPATHY OF UNDETERMINED SIGNIFICANCE by a much higher risk of progression to symptomatic MULTIPLE MYELOMA.
A rare, aggressive variant of MULTIPLE MYELOMA characterized by the circulation of excessive PLASMA CELLS in the peripheral blood. It can be a primary manifestation of multiple myeloma or develop as a terminal complication during the disease.
Abnormal immunoglobulins characteristic of MULTIPLE MYELOMA.
A nonproliferative disorder of the PLASMA CELL characterized by excessive production and misfolding of IMMUNOGLOBULIN LIGHT CHAINS that form insoluble amyloid fibrils (see AMYLOID DEPOSITS) in various tissues. Clinical features include LIVER FAILURE; MULTIPLE MYELOMA; NEPHROTIC SYNDROME; RESTRICTIVE CARDIOMYOPATHY, and neuropathies.
A pyrazine and boronic acid derivative that functions as a reversible PROTEASOME INHIBITOR. It is used as an ANTINEOPLASTIC AGENT in the treatment of MULTIPLE MYELOMA and MANTLE CELL LYMPHOMA.
