RATIONALE: Drugs used in chemotherapy, such as 17-dimethylaminoethylamino-17-demethoxygeldanamycin (17-DMAG), work in different ways to stop cancer cells from dividing so they stop growing or die.
- Determine the maximum tolerated dose of 17-dimethylaminoethylamino-17-demethoxygeldanamycin (17-DMAG) in patients with an advanced malignant solid tumor or lymphoma.
- Determine the dose-limiting toxic effects and toxicity profile of this drug in these patients.
- Compare the effects of this drug on heat shock protein 90 (Hsp90) client proteins when assayed in peripheral blood mononuclear cells (PBMC) vs tumor tissue from patients treated with this drug.
- Correlate disturbances in key signaling pathways with administration of this drug in these patients.
- Determine the dose that alters key proteins in the majority of patients treated with this drug.
- Correlate serum proteomic patterns with target interactions or DMAG clinical effects in patients treated with this drug.
- Determine the pharmacokinetics of this drug in these patients.
OUTLINE: This is a single-center, dose-escalation study.
Patients receive 17-dimethylaminoethylamino-17-demethoxygeldanamycin (17-DMAG) IV over 1-2 hour on days 1 and 4 or days 2 and 5 weekly for 4 weeks. Treatment repeats every 4 weeks in the absence of disease progression or unacceptable toxicity.
Cohorts of 1-6 patients receive escalating doses of 17-DMAG until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of up to 6 patients experience dose-limiting toxicity. Once the MTD is determined, 10 additional patients are treated at the MTD.
PROJECTED ACCRUAL: Approximately 40 patients will be accrued for this study within 2 years.

A nitrogen mustard compound that functions as an ALKYLATING ANTINEOPLASTIC AGENT and is used in the treatment of CHRONIC LYMPHOCYTIC LEUKEMIA and NON-HODGKIN'S LYMPHOMA.
A leukemia/lymphoma found predominately in children and young adults and characterized LYMPHADENOPATHY and THYMUS GLAND involvement. It most frequently presents as a lymphoma, but a leukemic progression in the bone marrow is common.
B-cell lymphoid tumors that occur in association with AIDS. Patients often present with an advanced stage of disease and highly malignant subtypes including BURKITT LYMPHOMA; IMMUNOBLASTIC LARGE-CELL LYMPHOMA; PRIMARY EFFUSION LYMPHOMA; and DIFFUSE, LARGE B-CELL, LYMPHOMA. The tumors are often disseminated in unusual extranodal sites and chromosomal abnormalities are frequently present. It is likely that polyclonal B-cell lymphoproliferation in AIDS is a complex result of EBV infection, HIV antigenic stimulation, and T-cell-dependent HIV activation.
A form of undifferentiated malignant LYMPHOMA usually found in central Africa, but also reported in other parts of the world. It is commonly manifested as a large osteolytic lesion in the jaw or as an abdominal mass. B-cell antigens are expressed on the immature cells that make up the tumor in virtually all cases of Burkitt lymphoma. The Epstein-Barr virus (HERPESVIRUS 4, HUMAN) has been isolated from Burkitt lymphoma cases in Africa and it is implicated as the causative agent in these cases; however, most non-African cases are EBV-negative.
Two or more distinct types of malignant lymphoid tumors occurring within a single organ or tissue at the same time. It may contain different types of non-Hodgkin lymphoma cells or both Hodgkin and non-Hodgkin lymphoma cells.
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
