Abstract
Survivors of childhood leukemia are at risk of impaired growth and short stature as adults due to intensive combination chemotherapy and radiation injury. This study was undertaken to evaluate anthropometry in children treated for acute lymphoblastic leukemia (ALL). Children treated for ALL and off treatment for a minimum period of 2years were evaluated for height, weight and BMI. Z scores were calculated for height, weight and BMI: at induction, 6months after starting treatment, at end of treatment and at 2years after completion of therapy. Change in z scores were calculated and compared with CDC criteria and Agarwal standards for Indian children. Fifty two boys and 21 girls were analyzed. Height and weight z scores were seen to show a steep decrease during the initial intensive phase of therapy. The gain in height and weight continued to be slow during therapy and catch up occurred after cessation of therapy. On completion of therapy, patients were shorter, but not significantly so. Girls <9years were significantly shorter. Weight remained on the lower side of normal. Change of z scores was statistically significant for weight at end of treatment (p=0.032) and 2years after completion of treatment (p=0.00). BMI z score increased throughout the study period. Peak growth velocities were also late in the study subjects Anthropometric variables of height, weight and BMI are affected by ALL during therapy. Growth deceleration is maximum during the intensive phase of therapy. Catch up growth occurs but children remain smaller than their peers.
