The outcome of chemotherapeutic regimen by high-risk pre-B-cell protocol in ALL children.

Objective: The aim of this study was to investigate the outcome of chemotherapeutic regimen by high-risk pre-B-cell potocol in ALL children.

Methods: The cross-sectional study was conducted on 55 children who were treated with the Children Oncology Group (COG) protocol from September 2010 to February 2015 to evaluate the chemotherapeutic regimen results.

Results: There was a complete recovery rate of 76.4% during the first week after treatment. Three-year overall survival was 85.5% and five-year overall survival was 81%. Relapse rate after first remission was 20% and death after relapse was 50%. Thirty percent of total deaths were at the induction period. All of the deceased cases died due to sepsis.

Conclusion: Results showed that the survival rate increased. By choosing the COG protocol and by controlling infection in patients without considering the risk group we can improve survival rates.
