title: Nutritional assessment of children with hematological malignancies and their subsequent tolerance to chemotherapy.
abstract: BACKGROUND
  Our research goals were to assess the prevalence of malnutrition in children with cancer, observe malnutrition's effect on tolerance to chemotherapy, and establish malnutrition at onset as one of the prognostic factors in children with hematological malignancies.
  
  
  METHODS
  This prospective study examined children ages 1-15 years with a confirmed diagnosis of acute lymphoblastic leukemia (ALL) and non-Hodgkin lymphoma. Each child was subjected to a detailed history, anthropometric examination, and laboratory investigations. Based on the anthropometric measurements that used weight-for-age Z scores, we divided the children into 4 groups: group 1, without malnutrition; group 2, mild malnutrition; group 3, moderate malnutrition; and group 4, severe malnutrition. We analyzed data for each group regarding the behavior of blood indices, the quantum of hematological support, bone marrow remission status on day 28, adherence to protocol schedules, and complications in the first 4 months of intensive chemotherapy.
  
  
  RESULTS
  Of the 34 patients in the study (mean age, 7.1 years; male:female ratio, 1.6:1), 79% had deficient calorie intake and 74% had deficient protein intake. Packed cell requirements and complications were significantly higher in malnourished children, whereas the requirement for platelet transfusions was statistically insignificant. Also, 50%, 40%, 38%, and 44% of children in groups 1, 2, 3, and 4, respectively, completed chemotherapy within the specified time period. At the end of the induction phase, 92%, 60%, 87%, and 77% of the patients in groups 1, 2, 3, and 4, respectively, achieved bone marrow remission. No deaths occurred in group 1; 1 death each occurred in groups 3 and 4, and 2 in group 2. When these deaths were extrapolated to the weight/height ratio (acute malnutrition), we found that all occurred in children with malnutrition, a statistically significant result.
  
  
  CONCLUSIONS
  Malnutrition is widely prevalent in children with ALL in India and has a significant bearing on the occurrence of life-threatening complications and short-term outcomes in these children. Malnutrition is also a significant factor influencing treatment planning and therapeutic decisions.
