ABSTRACT
Primary Central Nervous System Lymphoma (PCNSL) is a rare neoplasm of B cell origin and constitute less than 1% of Non-Hodgkin's lymphoma (NHL). Histology is mainly of high grade and intermediate type. Although NHL is known to be highly sensitive to both irradiation and cytotoxic drugs, being a curable malignancy, the therapeutic results remain disappointing. Clinical observations on nine cases of PCNSL seen in one of the major cancer centres in India is presented in this paper. Radiotherapy combined with Chemotherapy although yielded encouraging initial response in these patients, the long term response was unsatisfactory with median survival for these patients being only 19 months. This warrants an alternative therapeutic approach to improve the dismal prognosis of PCNSL.

Epidural Cord Compression (ECC) by primary lymphomas is rare entity and constitutes less than 3% of total malignant lymphoma with Non-Hodgkin's Lymphoma (NHL), diffuse large cell type being the most common histological subtype. In this paper 16 cases of primary NHL with cord compression seen at the Department of Medical Oncology, during the period 1988-1990 are reviewed. At presentation all patients had undergone Laminectomy with decompression of epidural mass. The histological diagnosis of NHL was subclassified according to the International working formulation and was evaluated for disease process elsewhere in the body. All patients with ECC by lymphoma received high dose steroids with concurrent Radiotherapy (local) and combination Chemotherapy. These patients had longer duration of neurological deficit prior to treatment had poor response. After 6 courses of chemotherapy 50% of the patients had complete neurological recovery (CR), 31% had partial neurological recovery (PR) and in 19% there was no neurological recovery (NR).
