  1. Screening for Wilms Tumor in children with Beckwith-Wiedemann syndrome or idiopathic hemihypertrophy.

    Article - En anglais

    Background

    Children with Beckwith-Wiedemann syndrome and idiopathic hemihypertrophy (BWS/HH) are at increased risk for developing Wilms tumor and screening with abdominal sonography is frequently recommended.

    However, there is a paucity of published data supporting this strategy.

    The purpose of this study was to determine whether sonographic screening at intervals of 4 months or less reduced the proportion of late-stage Wilms Tumor (WT) in children with BWS/HH.

    Procedure.

    A case series analysis was employed to compare the proportion of late-stage (stage III or IV) Wilms tumor in patients with BWS/HH who were screened with sonography (n=15) to the proportion of late-stage Wilms tumor in unscreened patients with BWS/HH (n=59).

    Patients were identified from the BWS Registry and from previously published studies.

    Screened patients had sonograms at intervals of 4 months or less.

    Results

    None of the 12 screened children with Wilms tumor had late-stage disease, whereas 25 of 59 (42%) of unscreened children had late-stage Wilms tumor, a difference that was statistically significant (P<0.003).

    Three children had false positive screening studies.

    They were operated on for suspected Wilms tumor but the lesions proved to be complicated renal cysts (n=2) or nephroblastomatosis (n=1).

    Conclusions

    This study suggests that children with BWS/HH may benefit from screening sonograms at intervals of 4 months or less. (...)
