[Show abstract][Hide abstract] ABSTRACT: Though an increasing number of chemotherapy- and radiotherapy-related leukaemias are being reported, acute promyelocytic leukaemia developing as a therapy-related second malignancy is still uncommon. Here we report a case of acute promyelocytic leukemia, microgranular variant, developing in a case of intracranial malignant ependymoma, 1.5 years following treatment with craniospinal radiotherapy.

[Show abstract][Hide abstract] ABSTRACT: 60 patients studied at the Tata Memorial Hospital from January 1976 to December 1982 were diagnosed as having T-cell acute lymphoblastic leukemia (ALL) by nonimmune rosette formation with sheep red blood cells. The analysis revealed a high incidence of mediastinal mass (50%) and extramedullary infiltration at presentation. The majority of patients (62%) presented with a high WBC count (greater than 50,000/mm3). Unipolar acid phosphatase activity was observed in 90% of patients. The remission rate with a combination treatment of adriamycin, vincristine and prednisolone was found to be 95%. Long-term survival was around 30%. More aggressive or innovative treatments will be needed to improve the results in T-cell ALL.
[Show abstract][Hide abstract] ABSTRACT: Leukemic cells from 124 acute lymphoblastic leukemia (ALL) and 31 chronic lymphatic leukemia (CLL) were examined for sheep erythrocyte receptor (E), surface immunoglobulin (Slg) and their reactivity with a panel of monoclonal antibodies recognizing specific surface antigens including pan-T, Common ALL and Ia antigens. In acute lymphatic leukemia, 33% of patients reveal T-cell receptor associated with higher age group, mediastinal mass and high WBC count. Common ALL was predominant between 2 and 9-yr age group. Among chronic lymphatic leukemia, 2 patients were found to be T-CLL while 29 revealed presence of Slg. Ia antigen was detected in 44.4% of ALL and 64% fo CLL patients. The pattern of surface marker observed in our series may be related to our life style, socio-economic and environmental factors.
