OBJECTIVES: To investigate the prognosis of childhood T-lymphoblastic lymphoma (T-LBL) treated with acute lymphoblastic leukemia (ALL) regimen and related influencing factors.
METHODS: A retrospective analysis was performed for the prognostic characteristics of 29 children with T-LBL who were treated with ALL regimen (ALL-2009 or CCCG-ALL-2015 regimen) from May 2010 to May 2022.
RESULTS: The 29 children with T-LBL had a 5-year overall survival (OS) rate of 84%±7% and an event-free survival (EFS) rate of 81%±8%. The children with B systemic symptoms (unexplained fever >38°C for more than 3 days; night sweats; weight loss >10% within 6 months) at initial diagnosis had a lower 5-year EFS rate compared to the children without B symptoms (P<0.05). The children with platelet count >400×109/L and involvement of both mediastinum and lymph nodes at initial diagnosis had lower 5-year OS rates (P<0.05). There were no significant differences in 5-year OS and EFS rates between the children treated with CCCG-ALL-2015 regimen and those treated with ALL-2009 regimen (P>0.05). Compared with the ALL-2009 regimen, the CCCG-ALL-2015 regimen reduced the frequency of high-dose methotrexate chemotherapy and the incidence rate of severe infections (P<0.05).
CONCLUSIONS: The ALL regimen is safe and effective in children with T-LBL. Children with B systemic symptoms, platelet count >400×109/L, and involvement of both mediastinum and lymph nodes at initial diagnosis tend to have a poor prognosis. Reduction in the frequency of high-dose methotrexate chemotherapy can reduce the incidence rate of severe infections, but it does not affect prognosis.
