Brief summary

This study will evaluate the response and long-term effects of alpha-interferon in patients with lymphomatoid granulomatosis (LYG). The disease causes proliferation of destructive cells involving the lungs, skin, kidneys, and central nervous system. Patients ages 12 and older who have LYG and who are not pregnant, or breast feeding may be eligible for this study. Alpha interferon or chemotherapy, or both, will be used. Alpha interferon is a protein the body naturally produces. If patients have grade 3 disease, they will usually receive etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin (EPOCH)-rituximab (EPOCH-R) chemotherapy (each letter representing a drug). If patients have grade 1 or 2 disease, they will usually receive alpha interferon. If patients have LYG after receiving alpha interferon and/or EPOCH-R, they may receive rituximab alone or with alpha interferon. Rituximab is an antibody, binding to a specific molecule cluster of differentiation 20 (CD20) present on most B-cell lymphomas. Doses of several drugs in EPOCH-R may be increased if patients tolerated them in the previous cycle. If patients respond to EPOCH-R but still have low grade LYG, they may receive alpha interferon. Researchers will also try to obtain a biopsy of patient's lesions, to help in understanding the disease. Patients self-administer alpha interferon by injection under the skin three times weekly. They will visit the clinic every 2 to 12 weeks for follow-up. Patients will receive alpha interferon for 1 year after LYG goes away, depending on response. EPOCH-R has these drugs: rituximab by vein on Day 1; prednisone by mouth on Days 1 to 5; etoposide, doxorubicin, and vincristine as a continuous intravenous infusion on Days 1 to 5; and cyclophosphamide by intravenous injection over 1 hour on Day 5. Each cycle lasts 3 weeks: 5 days of chemotherapy and 16 days of no chemotherapy. Etoposide, doxorubicin, and vincristine are infused through a small pump worn by patients. The drugs are given over 5 days through a central intravenous catheter. There are two cycles of EPOCH-R beyond a maximum response, with six cycles maximum. To reduce harm to bone marrow, patients receive granulocyte colony stimulating factor (G-CSF), self-administered by injection under the skin daily for approximately 10 days between chemotherapy cycles. If at the end of therapy, patients have a complete response, treatment will stop. If there is residual low-grade disease, patients may receive alpha interferon. Alpha interferon can have flu-like side effects of headache, fever, chills, and body aches. EPOCH-R drugs can cause gastrointestinal problems, hair loss, and weakness. Granulocyte colony-stimulating factor (G-CSF) can cause bone pain, body aches, and hair thinning. Chemotherapy can cause some patients to develop leukemia. This study may or may not have a direct benefit for participants. It is not certain whether the new therapy will help decrease tumors. However, knowledge gained may improve the understanding of and treatment for LYG. ...

Detailed description

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 Epstein-Barr virus (EBV) related lymphoproliferative disorders (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)-etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin rituximab (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 LYG (or a diagnosis consistent with LYG) confirmed by the Laboratory of Pathology, National Cancer Institute (NCI). * Patients with any stage of disease will be eligible. * Previously untreated and treated patients are eligible. * Patients aged 12 or older will be eligible. DESIGN: * Interferon is used as initial treatment in patients with grades 1 and 2 LYG. Patients will receive interferon for one year past complete remission (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.

Design outcomes

Primary

MeasureTime frameDescription
Overall Response Rate (ORR)From study enrollment and throughout treatment, up to a maximum of 40 months for the 2 interferon groups and 8 months for the 2 EPOCH-R groups.Overall response rate will be classified as the following: complete remission (CR), partial remission (PR), disease progression or disease stabilization measured by the Response Criteria. CR is no evidence of active disease on restaging for at least 2 months duration. All lesions must have decreased by \> 75%, be gallium or positron emission tomography (PET) negative (if obtained) and be stable for \> 3 months without new lesions appearing. PR is 50% or greater decrease in the sum of the products of the diameters of all measurable lesions for at least one month. Disease progression is 25% or greater progression in the sum of the products of the diameter of any measurable lesion over one month or the appearance or any new lesion consistent with metastatic disease. Disease stabilization is no change in the sum of the products of the diameters of all measurable lesions over two months and no new lesions consistent with disease.
Progression Free Survival (PFS)Assessed from date of study enrollment until time of disease relapse, disease progression, death, or last follow-up, whichever comes first, up to a maximum of 27 years for the 2 interferon groups and 20 years for the 2 EPOCH-R groups.PFS is defined as the duration of time from the date of study enrollment until the date of disease relapse, disease progression, death, or last follow-up, whichever occurs first, using the Kaplan-Meier method. Response was assessed by the Lugano Classification Response Criteria for Non-Hodgkin lymphoma (NHL). Disease progression is defined as an increase of ≥ 50% from the product of the perpendicular diameter (PPD) nadir and an increase in longest transverse diameter of a lesion (LDi) or shortest axis perpendicular diameter (SDi) from nadir of \>0.5 cm for lesions \<2 cm or \>1.0 cm for lesions \>2 cm.
