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.

Clinical Details

Official title: A Randomized Phase II Study of Dose-Adjusted EPOCH-R and R-VACOP-B in Primary Mediastinal (Thymic) Large B-Cell Lymphoma

Study design: Allocation: Randomized, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Complete response rate

Secondary outcome:

Two-year progression-free survival

Overall survival

Toxicity as assessed by NCI CTCAE v3.0

Immunohistochemical staining results

Correlation of soluble CD30 levels with disease activity in PMLCL

Detailed description: 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


- 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.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

- Arm I (EPOCH-R): Patients receive rituximab IV on day 1; etoposide IV, doxorubicin

hydrochloride IV, and vincristine sulfate IV continuously over 96 hours on days 1-4; cyclophosphamide IV over 30 minutes on day 5; and oral prednisone twice daily on days 1-5. Treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity.

- Arm II (R-VACOP-B): Patients receive rituximab IV and doxorubicin hydrochloride IV on

day 1 of weeks 1, 3, 5, 7, 9, and 11; cyclophosphamide IV over 30 minutes on day 1 of weeks 1, 5, and 9; etoposide IV over 1 hour on day 1 and then orally on days 2 and 3 of weeks 3, 7, and 11; bleomycin sulfate IV and vincristine sulfate IV on day 1 of weeks 2, 4, 6, 8, 10, and 12; and oral prednisone on days 1-7 of week 1 and then every other day in weeks 2-10. In both arms, patients undergo PET/CT scans at baseline, mid-therapy, and after completion of chemotherapy. Patients with stable or progressive disease after completion of chemotherapy are removed from the study. Patients with complete response undergo observation. Patients with partial response undergo involved-field radiotherapy to any area of bulky disease at diagnosis and to any FDG-avid area on PET scan 3-4 weeks after completion of chemotherapy. These patients then undergo additional PET/CT scan at 8-10 weeks after completion of radiotherapy. Blood samples are collected at baseline, during mid-therapy restaging, and after completion of chemotherapy for analysis of soluble CD30 levels by ELISA. Previously collected tissue samples are obtained for biomarker analysis by IHC. After completion of study therapy, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.
