levoleucovorin and Orbital-Neoplasms

Twenty patients with orbital lymphomas were treated and followed over a 14-year period. Ten of these patients had well-differentiated lymphocytic lymphoma (WDL), and all of them were clinical stage IE. Five patients had nodular poorly differentiated lymphocytic lymphomas (NPDL), three patients had diffuse histiocytic lymphomas (DHL), one had nodular mixed-cell lymphoma, and one had diffused mixed-cell lymphoma. The patients with WDL received local radiation therapy, and all of them entered completed remissions. The projected survival at 10 years was 100% for these patients. The patients with low-grade lymphomas with advanced disease were treated with chlorambucil and prednisone or cytoxan and vincristine. The patients with high-grade lymphomas received treatment with methotrexate, cyclophosphamide, doxorubicin, vincristine, bleomycin, dexamethasone (mBACOD) or cyclophosphamide, vincristine, methotrexate, cytosine arabinoside, leucovorin (COMLA). The overall survival estimate for all patients was 63% at 10 years. The disease-free survival was 49% at 10 years. The patients with high-grade lymphomas had a poor prognosis, with no survivors after 4 years. This study suggests that patients with WDL usually present with localized disease to the involved orbit, and have an excellent prognosis with radiation therapy alone. Patients with high-grade orbital non-Hodgkin's lymphomas have a poor outcome despite use of aggressive combination chemotherapy regimens.

Ten patients with non-Hodgkin's lymphoma primarily affecting the orbital region were evaluated at Michael Reese Hospital and Medical Center, Chicago, between 1976 and 1983. Diagnoses were based on the histopathologic classification systems of the Working Formulation of the Non-Hodgkin's Lymphomas and Rappoport. Sequential staging procedures performed at the time of diagnosis included liver-spleen scans, Technecium-99 bone scans, gallium 67 scans, computerized axial tomograms of the orbit and abdomen, bone marrow examination and cerebral spinal fluid analyses. Adverse prognostic factors included the following: orbital bone erosions, Stage IV disease, and large cell or mixed cell, diffuse histologic features. The type of histopathologic findings combined with the results of sequential staging procedures is useful in identifying those patients who would benefit most from systemic chemotherapy.
