Multicatheter interstitial brachytherapy versus intensity modulated external beam therapy for accelerated partial breast irradiation: A comparative treatment planning study with respect to dosimetry of organs at risk.

CONCLUSIONS: The target volume can be appropriately irradiated by both techniques, but MIBT generally spares normal tissues and organs at risk better than IMRT. Except for the heart, other critical structures receive less doses with brachytherapy. To observe whether these dosimetric findings translate into clinical outcome more studies are needed with assessment of toxicity profiles. PMID: 27544819 [PubMed - as supplied by publisher]
