title: Auxologic data and hormonal profile in long-term survivors of childhood acute lymphoid leukemia.
abstract: OBJECTIVE
  Eighty patients, 50 girls and 30 boys 13.5 +/- 4.09 years of age, on continuous first remission, were evaluated 7.9 +/- 3.2 years after the diagnosis of acute lymphoid leukemia (ALL).
  
  
  RESULTS
  All patients were treated according to current protocols. Cranial irradiation dose was 1,800 rad in 10 fractions for 50 patients, and 2,400 rad in 18 fractions for the remaining 30. The mean percentile and SDS for height were 42.5 +/- 26 and -0.3 +/- 1.1 for boys, and 37.8 +/- 15.3 and -0.54 +/- 0.9 for girls, respectively. The final height and the corresponding SDS was 171 +/- 5.75 cm and -0.35 +/- 0.8 for boys, and 158 +/- 7.1 cm and -0.89 +/- 1.1 for girls, respectively. Using skin fold thickness, obesity was observed in a high percentage of patients. The head circumference (HC) percentile was 36.8 +/- 24 for boys and 40.9 +/- 29 for girls, and was even lower (30.96 +/- 25.5) for those who received a radiation dose of 2,400 rad. Menarche was earlier in girls with ALL than in normal girls (11.6 +/- 1.5 vs. 12.4 +/- 1.02 years). Testicular size was within normal limits, except in three boys whose size was at or below the third percentile. In two of them, testes had been irradiated. The mean thyroxin, thyroid-stimulating hormone, and prolactin values were within normal limits (8.6 +/- 2 micrograms/dl, 2.6 +/- 1.1 microU/dl, and 5.9 +/- 4.8 ng/ml, respectively). The somatomedin-C values for patients in the prepubertal stage were 1.49 +/- 0.85 versus 0.96 +/- 0.6 in the controls (p < 0.05), whereas for patients in the pubertal stage they were 1.92 +/- 1 versus 1.88 +/- 1 in the controls. The sex steroid and dehydroepiandrosterone sulfate values were within normal limits. In a high percentage of children, follicle-stimulating hormone and luteinizing hormone values were above the normal range for their age, sex, and pubertal stage. The mean glycosylated hemoglobin values were normal.
  
  
  CONCLUSIONS
  1. Linear growth, although impaired in the group as a whole, is within the normal range for the majority of children with ALL. A small percentage of children have significantly impaired growth, and must be identified early and receive appropriate therapy. 2. Obesity is more frequently present in patients with ALL. 3. HC is lower than expected, indicating impaired brain growth, which is worse in children irradiated with 2,400 rad. 4. Menarche is earlier and the gonadotrophin level is higher than normal, suggestive of either hypothalamic dysfunction, subtle ovarian failure, or both.
