Acute leukemia with normal platelet count at diagnosis.

Area of Science:

• Pediatric Hematology Oncology
• Leukemia Research
• Clinical Diagnostics

Background:

• Thrombocytopenia is common in childhood leukemia.
• Platelet counts at diagnosis may impact acute lymphoblastic leukemia (ALL) outcomes.
• Understanding prognostic markers in pediatric ALL is crucial for treatment stratification.

Purpose of the Study:

• To investigate the clinical significance of normal platelet counts in children diagnosed with acute lymphoblastic leukemia (ALL).
• To determine if platelet count at diagnosis correlates with presenting features and remission rates in pediatric ALL.
• To compare characteristics of ALL patients with and without thrombocytopenia.

Main Methods:

• Retrospective analysis of 202 children diagnosed with acute lymphoblastic leukemia (ALL).
• Categorization of patients based on platelet count at diagnosis (≥150 x 10(9)/l vs. <150 x 10(9)/l).
• Comparison of clinical manifestations, laboratory findings (leukocytosis, anemia, bone marrow blasts), and remission rates between groups.

Main Results:

• 17.8% of pediatric ALL patients had platelet counts ≥150 x 10(9)/l at diagnosis.
• ALL patients without thrombocytopenia were more likely male, exhibited less bleeding, and had lower leukocytosis, anemia, and bone marrow blast percentages.
• Absence of thrombocytopenia in ALL patients correlated with a significantly higher probability of continuous complete remission (p<0.01).

Conclusions:

• Normal platelet count at diagnosis in pediatric acute lymphoblastic leukemia (ALL) is associated with less severe disease manifestations.
• Patients with ALL and normal platelet counts demonstrate a significantly better prognosis, indicated by higher rates of continuous complete remission.
• Platelet count at diagnosis serves as a potential prognostic indicator in childhood ALL.
