Combination Chemotherapy and Rituximab in Treating Patients With Primary Mediastinal Diffuse Large B-Cell Lymphoma

NCT00689845

Description:

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving rituximab together with one of five different combination chemotherapy regimens may kill more cancer cells. PURPOSE: This clinical trial is studying giving rituximab together with combination chemotherapy to see how well it works in treating patients with primary mediastinal diffuse large B-cell lymphoma.

Detailed Description

OBJECTIVES:

Primary

- To systematically analyze the phenotype and molecular characteristics in patients with primary mediastinal diffuse large B-cell lymphoma.

- To determine the PET response rate following chemoimmunotherapy in these patients.

Secondary

- To obtain data, on a nonrandomized basis, regarding the outcomes of treatment using different chemoimmunotherapy regimens and using or omitting mediastinal radiotherapy, depending upon the practice of the participating institutions.

- To analyze progression-free and overall survival in patients treated with these regimens.

OUTLINE: This is a multicenter study.

Patients receive any one of the following standard chemoimmunotherapy regimens.

- Cohort 1 (R-CHOP-21): Patients receive rituximab IV, cyclophosphamide IV, doxorubicin hydrochloride IV, and vincristine IV on day 1 and oral prednisolone on days 1-5. Treatment repeats every 21 days in the absence of disease progression or unacceptable toxicity.

- Cohort 2 (R-CHOP-14): Patients receive rituximab IV, cyclophosphamide IV, doxorubicin hydrochloride IV, and vincristine IV on day 1, oral prednisolone on days 1-5, and filgrastim (G-CSF) subcutaneously (SC) on days 5-12. Treatment repeats every 14 days in the absence of disease progression or unacceptable toxicity.

- Cohort 3 (R-MACOP-B): Patients receive rituximab IV on days 1, 22, 43, 64, 85, and 106; cyclophosphamide IV and doxorubicin hydrochloride IV on days 1, 15, 29, 43, 57, and 71; methotrexate IV on days 8, 36, and 64; vincristine IV on days 8, 22, 36, 50 ,64, and 78; bleomycin IV on days 22, 50, and 78; and oral prednisolone on days 1-84, followed by a taper.

- Cohort 4 (R-VACOP-B): Patients receive rituximab IV on days 1, 22, 43, 64, 85, and 106; cyclophosphamide IV on days 1, 29, and 57; doxorubicin hydrochloride IV on days 1, 15, 29, 43, 57, and 71; etoposide phosphate IV on days 15, 16, 43, 44, 71, and 72; vincristine IV and bleomycin IV on days 8, 22, 36, 50, 64, and 78; and oral prednisolone on days 1-84, followed by a taper.

- Cohort 5 (R-ACVBP): Patients receive rituximab IV, doxorubicin hydrochloride IV, and cyclophosphamide IV on day 1; vindesine IV and bleomycin IV on days 1 and 5; oral prednisone on days 1-5; methotrexate intrathecally on day 2; and G-CSF SC on days 6-13 for 4 courses in the absence of disease progression or unacceptable toxicity. After completion of 4 courses of R-ACVBP, patients receive consolidation therapy comprising high-dose methotrexate IV, rituximab IV, ifosfamide IV, etoposide phosphate IV, and cytarabine SC according to protocol GELA LNH03-2B.

Patients with an International Prognostic Index score of 4 or greater or disease in close proximity to the spinal cord or cerebral meninges may receive prophylactic treatment to the CNS according to local protocol.

Beginning 8 weeks after completion of chemoimmunotherapy, patients undergo radiotherapy to the original tumor volume according to local protocol.

Fresh or fixed tissue from prior biopsy is obtained if possible. Samples are analyzed for CD3, CD20, CD30, CD15, CD10, Bcl-6, Bcl-2, MAL protein (if available), and Ki-67 via immunohistochemistry.

After completion of study treatment, patients are followed periodically.
