Children With Acute Lymphoblastic Leukemia in Romania: Results From a Decade-Long Single-Center Study

Acute lymphoblastic leukemia (ALL) is the most prevalent cancer in children, with continuously improving survival rates. As few studies in Romania have analyzed ALL patients and disease characteristics or survival, we conducted a retrospective study on 158 patients diagnosed with ALL admitted to the Department of Pediatric Oncology and Hematology at the Emergency Hospital for Children, Cluj-Napoca, Romania, from January 2011 until April 2021. The most important objectives of the study are to establish full profiles of the patients and ALL, remission rates, relapses, and deaths, an epidemiology analysis to determine the incidence of ALL for comparison with the standard European population, and also to assess survival by the most important parameters, including minimal residual disease (MRD).
