Prolonged disease-free survival in pediatric non-Hodgkin's lymphoma using ifosfamide-containing combination chemotherapy.
Pediatric non-Hodgkin's lymphoma (NHL) constitutes 16 per cent of pediatric malignancies reported to the National Cancer Institute (NCI) in Cairo. The adopted treatment for these cases was, from 1982 to July 1985, a modified St Jude's regimen consisting of: vincristine, cyclophosphamide, adriamycin, prednisone and intrathecal methotrexate for the first 6 weeks for induction, followed by cranial irradiation for cranial prophylaxis. Patients in remission received maintenance therapy for 18 months. Of 32 patients complete remission (CR) was achieved in 24 patients (75 per cent); partial remission (PR) in one patient (3 per cent); five patients showed no response (15 per cent) while two patients died during the induction phase. At 60+ months follow-up, 60 per cent of cases are still alive, disease-free, and overall survival is 66 per cent. A new protocol was adopted in 1985, consisting of alternating cycles: A and B, for 4-8 cycles. Cycle A: cyclophosphamide, high dose ara-C, adriamycin, and vincristine. Cycle B: ifosfamide, methotrexate, VP 16, with intrathecal methotrexate. The response in 39 cases is: CR in 31 cases (82 per cent); PR in four cases (10 per cent); no response in three cases (8 per cent). At 60+ months, the disease-free survival is 60 per cent, and overall survival 80 per cent. This new protocol has the advantage of: short duration of therapy and so better patient compliance, no maintenance therapy or cranial irradiation with its sequelae in the future. Moreover, it has a better overall survival.
