简要总结
RATIONALE: 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. 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. Giving rituximab together with combination chemotherapy may kill more cancer cells. It is not yet known which combination chemotherapy regimen is more effective when given with rituximab in treating large B-cell lymphoma.
PURPOSE: This randomized phase II trial is studying how well rituximab and combination chemotherapy work when given with or without bleomycin sulfate in treating patients with primary mediastinal large B-cell lymphoma.
详细描述
OBJECTIVES:
Primary
- To determine the complete response rate based on PET/CT scan criteria in patients with primary mediastinal large B-cell lymphoma (PMLCL) treated with dose-adjusted rituximab, etoposide, doxorubicin hydrochloride, vincristine sulfate, cyclophosphamide, and prednisone with or without bleomycin sulfate.
Secondary
- To characterize the progression-free survival (PFS) of patients treated with these regimens.
- To assess the toxicity profiles associated with these regimens in these patients.
- To determine the prognostic significance of a mid-therapy PET scan and an end-of-therapy PET scan in achieving complete response and in predicting 2-year PFS of patients treated with these regimens.
- To explore the effect of involved-field radiotherapy on 2-year PFS of patients who are PET positive at the end of chemotherapy.
- To explore the efficacy of an end-of-therapy PET/CT scan in predicting which patients can avoid radiotherapy.
- To characterize the overall survival of patients treated with these regimens.
- To prospectively validate a pattern of immunohistochemical staining, including nuclear c-REL, TRAF-1, c-JUN, and Gal1, to accurately distinguish PMLCL from other lymphoid malignancies.
- To determine if levels of soluble CD30 correlate with disease activity in PMLCL.
