Treatment of pediatric XXXX with interstitial brachytherapy: Peter MacCallum Cancer Institute experience with four cases.

@entity1 @entity150 @entity5
PURPOSE: To describe early outcome and technical treatment aspects of four @entity1 with pediatric @entity5 receiving local therapy using interstitial brachytherapy at the Peter MacCallum Cancer Institute since 1991. METHODS AND MATERIALS: Two @entity1 with primary @entity150 and two @entity1 with primary @entity5 received interstitial brachytherapy with needle-template techniques following chemotherapy. Two @entity1 were treated for salvage following local failure after primary chemotherapy and two @entity1 electively after initial induction chemotherapy, one following limited surgical excision. Three @entity1 were treated exclusively with brachytherapy with doses of 50-55 Gy (LDR), and one @entity1 also received external beam radiation. RESULTS: Resultant implants, dosimetry, and dose prescriptions are described and illustrated. Follow-up is short (14-27 months), but all @entity1 remain well without significant sequelae. One @entity1 required salvage surgery for local failure. CONCLUSION: Interstitial brachytherapy using needle-template techniques described is an ideal method of local ablative therapy for pediatric @entity5 . Functional and late sequelae should be less than that of radical surgery or external beam radiation. There are technical and practical advantages compared with other brachytherapy techniques described in the literature.
