Ultrasound-guided drug delivery in cancer
نویسندگان
چکیده
Recent advancements in ultrasound and microbubble (USMB) mediated drug delivery technology has shown that this approach can improve spatially confined delivery of drugs and genes to target tissues while reducing systemic dose and toxicity. The mechanism behind enhanced delivery of therapeutics is sonoporation, the formation of openings in the vasculature, induced by ultrasound-triggered oscillations and destruction of microbubbles. In this review, progress and challenges of USMB mediated drug delivery are summarized, with special focus on cancer therapy.

Ultrasound-mediated targeted drug delivery is a therapeutic modality under development with the potential to treat cancer. Its ability to produce local hyperthermia and cell poration through cavitation non-invasively makes it a candidate to trigger drug delivery. Hyperthermia offers greater potential for control, particularly with magnetic resonance imaging temperature measurement. However, cav...

متن کاملUltrasound-guided boost irradiation of tumor cavity after lumpectomy in breast cancer
Background: After breast conserving surgery, most recurrences occur around the primary tumor site. This justifies the use of boost radiotherapy to the primary site of tumor. Surgical scar is not always a good surrogate for the location of the lumpectomy cavity. The aim of this study was to evaluate ultrasonic guidance for detection of the lumpectomy cavity after breast conserving surgery ...
