Insights
Childhood leukemia treatment improved survival rates, with over 50% of acute lymphoblastic leukemia (ALL) patients alive at 3 years. Bimonthly Vincristine-Prednisolone maintenance therapy proved more effective than monthly treatments.
Area of Science:
- Pediatric Oncology
- Hematology
- Clinical Trials
Background:
- The Hungarian Study Group for Childhood Leukaemia was established in 1971 to standardize treatment protocols.
- Complex chemotherapy regimens were implemented for childhood leukemia patients.
Purpose of the Study:
- To evaluate the survival rates of children with leukemia undergoing uniform treatment schedules.
- To compare the efficacy of two different maintenance therapy protocols for acute lymphoblastic leukemia (ALL).
Main Methods:
- A cohort of 391 children with leukemia received chemotherapy based on established treatment schedules.
- Two maintenance therapy strategies were compared starting in 1974: monthly "pulses" versus every-second-month "pulses" of Vincristine-Prednisolone.
Main Results:
- Survival rates showed an increasing trend, with over 50% of ALL patients surviving 3 years post-treatment initiation.
- One patient achieved a complete remission lasting over 9 years.
- Bimonthly Vincristine-Prednisolone "pulses" demonstrated superior outcomes compared to monthly "pulses".
Conclusions:
- Uniform treatment schedules have improved survival in childhood leukemia.
- Optimized maintenance therapy, specifically bimonthly Vincristine-Prednisolone, enhances long-term remission rates in ALL patients.
Abstract:
391 children received complex chemotherapy according to uniform treatment schedules, proposed by the Hungarian Study Group for Childhood Leukaemia, which was established in 1971. Survival among the patients showed an increasing tendency: more than 50% of patients with ALL are stille alive 3 years after the beginning of treatment. One patient is in complete remission 9 3/4 years after the establishment of the diagnosis. Two types of maintenance therapy were investigated among the patients entered for this study in 1974. "Pulses" with Vincristine-Prednisolone every second month were found to be more optimal than monthly "pulses".

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
