Samenvatting

BACKGROUND: We conducted an integrated analysis of clinical data to describe long-term effects of bevacizumab on growth and bone development in pediatric and adolescent patients with solid tumors.

PROCEDURE: Clinical data were pooled from five phase I/II trials of bevacizumab versus chemotherapy: BERNIE, HERBY, and AVF4117s enrolled newly diagnosed patients, AVF3842s and AVF2771s enrolled patients with relapsed/refractory disease. Height, weight, body mass index (BMI), and bone-age data were pooled by treatment group. Growth charts were used to track and monitor growth in relation to a reference population of healthy children. Bone age was measured based on X-ray of the left hand and wrist. Analyses were exploratory/descriptive.

RESULTS: Overall, 268 patients received bevacizumab ± chemotherapy and 135 received chemotherapy alone. Baseline characteristics were generally balanced. Median duration of long-term follow-up was 41.8 months (range, 2.4-75.1) with bevacizumab and 22.9 months (range, 2.8-69.2) with chemotherapy alone. Patients had age-appropriate baseline height and weight. Mean height and weight percentiles decreased over time in both treatment groups, but remained within the normal range (height: mean standard deviation score [SDS] range -2 to +3; weight: mean SDS range -2 to +1). Similar trends were seen in BMI. A tendency for reduced growth velocity relative to the reference population was observed at 6 months and 1 year in both groups, but there was no additional decrease for patients receiving bevacizumab.

CONCLUSION: Bevacizumab did not appear to have additional negative effects on growth or development of pediatric and adolescent patients with solid tumors.
