During 1984-1986, a total of 128 children with acute lymphoblastic leukemia (ALL) were treated with an induction-consolidation regimen consisting of doxorubicin, vincristine, cytosine-arabinoside, and prednisolone. One hundred two (80%) patients belonged to high-risk group. The complete remission rate for all the patients was 91%. The event-free survival at 5 years was 32.0% +/- 23%. On multivariate analysis the event-free survival and disease-free survival was not altered by age, sex, WBC count, platelet count, LDH level, and surface phenotype. Infection due to prolonged marrow aplasia was a common complication, leading to mortality of 8 patients during induction and 33 patients during first remission. The relapse rate has been 36% (42 patients). The predominance of high-risk ALL in the Indian population underscores the need for intensive therapy. Improved supportive care during induction and remission seems essential to decrease therapy-related mortality, leading to improved survival.

Eight patients with advanced/recurrent retinoblastomas were treated with sequential combination chemotherapy incorporating cyclophosphamide, cisplatin, adriamycin, and etoposide. All patients achieved complete clinical response (CR) at the end of the first 75 day cycle. Three patients developed recurrence of which 2 patients had recurrence in the central nervous system and 1 patient had local recurrence. Median time to treatment failure was 30 weeks. Two patients succumbed to chemotherapy related neutropenic sepsis. One patient is alive and disease free for 72 weeks from start of treatment. This combination chemotherapy shows promise in patients with advanced/recurrent retinoblastoma and merits further study.
