Resumen:
Background. Acute lymphoblastic leukemia (ALL) is the most common cancer in childhood. Patients are classified according to clinical, biological, and molecular characteristics as well as their response to initial therapy. The objective of this study is aimed to characterize the diagnostic findings in a sample of Mexican patients with ALL and to identify clinical differences according to crude mortality. Methods. We reviewed clinical records of 391 pediatric ALL patients in nine hospitals in Mexico affiliated with the Seguro Popular insurance program. Results. Included in this study were 296 living patients and 95 deceased patients. Mean age was 6.48 years and 8.31 years for living and deceased patients, respectively. Signs and symptoms associated with seeking medical care were fever, pallor, fatigue and weakness. The main hematologic abnormalities were anemia and thrombocytopenia. The largest proportion of blasts in peripheral blood was observed in the group of deceased patients; 86.4% of the sample had immunophenotype in the clinical record and only 11.2% had cytogenetic study. One hundred forty eight patients were classified as standard risk and 230 patients as high risk. Conclusions. To characterize the population of children with ALL allows health systems to be aware of the features of patients with ALL and to implement specific actions and to develop strategies so that all patients have access to immunophenotype and cytogenetic studies.
