Methotrexate and Thiotepa in Treating Patients With Newly Diagnosed Primary CNS Lymphoma

2014-07-24 14:34:02 | BioPortfolio

Summary

RATIONALE: Drugs used in chemotherapy, such as methotrexate and thiotepa, work in different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of combining methotrexate with thiotepa in treating patients who have newly-diagnosed primary CNS lymphoma.

Description

OBJECTIVES:

- Determine the complete radiographic response in patients with newly diagnosed primary CNS lymphoma treated with methotrexate and thiotepa.

- Determine the duration of progression-free survival and overall survival of patients treated with this regimen.

- Determine the toxicity of this regimen in these patients.

- Determine whether tumor expression of BCL-6 is associated with response to this chemotherapy regimen and survival of these patients.

- Describe the relationship between initial response to steroids (if administered), response to this chemotherapy regimen, and survival of these patients.

OUTLINE: This is a multicenter study.

Patients receive thiotepa IV over 15 minutes on day 1. Patients also receive methotrexate IV over 4 hours on days 1 (8 hours after thiotepa) and 14. Beginning 24 hours after the start of methotrexate infusion, patients receive leucovorin calcium IV or orally every 6 hours until rescue is achieved. Treatment repeats every 28 days for up to 4 courses in the absence of disease progression or unacceptable toxicity. Patients achieving disappearance of enhancement of disease on MRI receive an additional 28-day course followed by maintenance therapy comprising thiotepa and methotrexate once a month for 11 courses.

Patients undergo neuro-ophthalmologic exams annually for 2 years.

Patients are followed every 2 months.

PROJECTED ACCRUAL: A total of 23-39 patients will be accrued for this study within 8-20 months.

Medical and Biotech [MESH] Definitions

The active metabolite of FOLIC ACID. Leucovorin is used principally as its calcium salt as an antidote to folic acid antagonists which block the conversion of folic acid to folinic acid.

A very toxic alkylating antineoplastic agent also used as an insect sterilant. It causes skin, gastrointestinal, CNS, and bone marrow damage. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), thiotepa may reasonably be anticipated to be a carcinogen (Merck Index, 11th ed).

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.
