Deskripsi
BACKGROUND:
- Lymphomatoid granulomatosis (LYG) is an angiocentric destructive proliferation of lymphoid cells predominantly involving the lungs, skin, kidneys, and central nervous system.
- It is divided into three grades, depending on the degree of necrosis and cellular atypia. The grades of disease are histologically-based and do not necessarily correlate with clinical outcome. However, like other EBV related LPD's, LYG can transform into an aggressive large B-cell lymphoma, which would be included within the grade 3 category. It is important to note that not all grade 3 lesions are a large B-cell lymphoma.
- Current evidence shows that LYG is a disease of B cells.
OBJECTIVES:
- To determine the response and long-term efficacy of alpha-Interferon in patients with lymphomatoid granulomatosis (LYG).
- To determine the response and long-term efficacy of dose-adjusted (DA)-EPOCH-R chemotherapy in patients with grade 3 LYG or in patients who have failed interferon.
ELIGIBILITY:
- Patients must have a tissue diagnosis of grade 1, 2 and/or 3 A/B LYG (or a diagnosis consistent with LYG) confirmed by the Laboratory of Pathology, NCI.
- Patients with any stage of disease will be eligible.
- Previously untreated and treated patients are eligible.
- Patients age 12 or older will be eligible.
- Female patients who are pregnant or lactating are not eligible to receive treatment but can be followed for natural history.
DESIGN:
- Interferon is used as initial treatment in patients with grades 1 and 2 LYG . Patients will receive interferon for one year past CR.
- Patients who progress after or during interferon, and patients with grade 3 LYG will receive aggressive combination chemotherapy with DA-EPOCH-R (rituximab, etoposide, doxorubicin, vincristine, cyclophosphamide and prednisone).
- Patients who fail one treatment approach may be crossed over to the other.
- A total of 105 patients will be enrolled at this single institution.

Experimental: 1 Interferon starting at 7.5 million Units subQ 3 times a week and increasing on the designated schedule,as tolerated. Patients continue taking interferon for 1 year beyond CR. Patients who progress may crossover to receive EPOCH-R. | Biological: 1 For LYG Grade 1 and 2: Interferon starting at 7.5 million Units subQ 3 times a week and increasing on the following schedule: 10 million U; 15 million U; 20 million U; 25 million U; and increased in 5 million U increments, as tolerated. Patients continue taking interferon for 1 year beyond CR. |
Experimental: 2 EPOCH-R every 3 weeks for up to 8 cycles, based on response. | Drug: 2 For LYG Grade 3: EPOCH-R (etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, rituxan) every 3 weeks for 6 cycles. |

Kriteria | - INCLUSION CRITERIA: Patients must have a tissue-diagnosis of grade 1, 2 and/or 3 A/B LYG (or a diagnosis consistent with LYG) confirmed by the Laboratory of Pathology, NCI. Final histopathologic classification and pathologic grade will be determined by Stephania Pittaluga, M.D. or her designee. Patients with any stage of disease will be eligible. Previously untreated and treated patients are eligible. Patients age 12 or older will be eligible. Informed consent must be obtained. EXCLUSION CRITERIA: Female patients who are pregnant or lactating are not eligible to receive treatment but can be followed for natural history. Patients with a history of coronary artery disease with angina pectoris, or a history of congestive heart failure will not be eligible to receive. DA-Epoch-R chemotherapy. Patients with significant renal (Cr. greater than 1.5 mg/dl or creatinine less than 40 cc/min) or hepatic (bilirubin greater than 2.5 u) dysfunction not due to tumor involvement will not be eligible to receive DA-EPOCH-R chemotherapy. Patients who in the opinion of the principle investigator are poor psychiatric or medical risk are not eligible. Patients who received > 450 mg/m2 doxorubicin and have a cardiac ejection fraction on echocardiogram less than or equal to 40% on protocol entry are not eligible to received DA-EPOCH-R. |
