Recruitment Status : Terminated (due to slow accrual (only 1 patient entered))

Brief Summary:
In this study, the investigators propose that the addition of rituximab will lower the risk of systemic and local relapses in patients with localized PBL. Patients will be treated with 6 cycles of RCHOP-14 or RCHOP-21. The administration of radiotherapy following chemotherapy is strongly recommended, based on the findings of the retrospective IELSG study, but will be at the discretion of the treating center.

Study Population
Previously untreated patients with localized DLBCL of the breast.

Inclusion Criteria:

  • Previously untreated patients with DLBCL of the breast.
  • Patients must have CD20 positive tumors.
  • Stage IE or IIE.
  • Must have at least one objective measurable or evaluable disease. Baseline measurements and evaluations must be obtained within 4 weeks of registration to the study.
  • Patients must have an ECOG performance status 0-2.

    • Creatinine Clearance > 50 ml/min
    • Total bilirubin < 2.0 mg/dl and AST < 2 x upper limit of normal. If documented hepatic involvement with lymphoma, total bilirubin can be < 3 x ULN, and AST < 5 x ULN.
    • Absolute neutrophil count > 1500/mm3 and platelet count > 100,000/mm3. If documented bone marrow involvement with lymphoma, absolute neutrophil count > 500/mm3 and platelet count > 50,000/mm3.
  • Patients must be age > 18 years.
  • Patients must have a normal left ventricular ejection fraction to be eligible.

Exclusion Criteria:

  • historical or radiographic evidence of CNS metastasis including previously treated, resected or asymptomatic brain lesions or leptomeningeal involvement.
