J Med Sci Jan ;21(2):81-3.

ver a period one year from January 2008 to January 2009. A total of 50 newly diagnosed ALL patients from all over Khyber Pukhtunkhwa were included in the study. Complete Blood Count and Bone Marrow findings of these patients were recorded and lumbar puncture was performed to assess the cerebrospinal fluid for central Nervous System involvement. Data was collected and statistically analyzed using soft ware SPSS 13. Results: Out of these 50 newly diagnosed ALL patients, 33 were males and 17 were female with a M:F ratio of 1.9:1. Two patients were found with nervous system involvement. L1 and L2 morphology was seen in 92% and 8% of patients respectively. The prognostically favorable age group (1-10 years) had 6.5% L2 morphology compared with 10.5% in the prognostically unfavorable age group (above 10 years) indicating poor prognosis with increasing age. The frequency of CNS involvement in ALL was found in 4 % of these children. Conclusion: For better prognosis, cerebrospinal fluid (CSF) examination must be done in every ALL child to find CNS involvement and initiate specific CNS directed therapy.
