Haemoglobin and prognosis in childhood acute lymphoblastic leukaemia.
نویسندگان
چکیده
Two hundred and nine children presenting consecutively with acute lymphoblastic leukaemia to a regional paediatric oncology unit were investigated to determine the prognostic significance of various factors at diagnosis. There was a strong positive correlation between the pretreatment haemoglobin level and the percentage of bone marrow blast cells in S phase of the cell cycle as assessed by flow cytometry. Patients with T- and B-cell leukaemia had significantly higher haemoglobin levels than non-B non-T patients. In patients with total white cell counts less than 20 X 10(9)/l, aged less than 13 years, and no mediastinal mass, there was no association of haemoglobin with length of first remission. However, among those with white blood counts greater than 20 +/- 10(9)/l there was a strong positive trend towards shorter remission with higher haemoglobin levels. Children with high white blood counts at diagnosis and low haemoglobin levels may have a better prognosis than predicted by the white blood count alone.

Acute lymphoblastic leukaemia (ALL) is the most frequent childhood cancer. During the last 50 years its prognosis has improved from zero probability of survival in the 1950s to more than 80% chance to be cured at the beginning of the 21st century. ALL is a highly chemosensitive disease and its successful treatment is a good indicator of the level of medical care that children with cancer get in...
