The prevalence of the metabolic syndrome among adults from the French childhood acute leukemia survivors' cohort was prospectively evaluated considering the type of anti-leukemic treatment received, and compared with that of controls. The metabolic profile of those patients was compared with that of controls. 3203 patients from a French volunteer cohort were age- and sex-matched 3:1 to 1025 leukemia survivors (in both cohorts, mean age: 24.4 years, female individuals: 51%). Metabolic syndrome was defined according to the National Cholesterol Education Program's Adult Treatment Panel III criteria. Metabolic syndrome was found in 10.3% of patients (mean follow-up duration: 16.3+/-0.2 years) and 4.5% of controls, (OR=2.49, p<0.001). Patients transplanted with total body irradiation presented the highest risk (OR=6.26, p<0.001); the other treatment groups also displayed a higher risk than controls, including patients treated with chemotherapy only. Odd ratios were 1.68 (p=0.005) after chemotherapy only, 2.32 (p=0.002) after chemotherapy and cranial irradiation, and 2.18 (p=0.057) in patients transplanted without irradiation. Total body irradiation recipients with metabolic syndrome displayed a unique profile compared with controls: smaller waist circumference (91 versus 99.6 cm, p=0.01), increased triglyceride levels (3.99 versus 1.5 mmol/l, p<0.001), fasting glucose levels (6.2 versus 5.6 mmol/l, p=0.049) and systolic blood pressure (137.9 versus 132.8 mmHg, p=0.005). By contrast, cranial irradiation recipients with metabolic syndrome had a larger waist circumference (109 versus 99.6 cm, p=0.007) than controls. Regardless of the anti-leukemic treatment, metabolic syndrome risk was higher among childhood leukemia survivors. Its presentation differed depending on the treatment type, thus suggesting divergent pathophysiology.
