Researchers take a 3D approach to breast density
Canadian and U.S. researchers have determined how measurements of volumetric breast density can be obtained from digital mammograms. The method builds upon previous work that allows the breast thickness to be determined precisely -- a key challenge when working in 3D.

Radiation therapy markers may have role in drug delivery
Given the proximity of inert implants such as fiducial markers and spacers to the target tumor, why not make more use of these devices? Researchers from Boston suggest they can be used to deliver radiosensitizing drugs or cytotoxic agents in situ, possibly improving efficacy without increasing radiation dose.

Optical sensor tracks radiotherapy treatment site breast motion
Postsurgical radiotherapy is an effective way of preventing breast tumors from reappearing, but the downside is the mismatch between ideal treatment plans and the doses actually delivered. Although conformal methods of delivery could address this issue, switching delivery techniques raises another potential problem: Will breast motion compromise the accuracy of a highly targeted radiotherapy regimen?

Can VMAT top IMRT for glioma treatment?
Intensity-modulated radiation therapy (IMRT) makes it easier to target brain tumors while reducing dose to critical structures nearby. But can volumetric-modulated arc therapy (VMAT) do even better? A retrospective planning study from Canada has revealed the pros and cons of making the switch.

VMAT bests IMRT for prostate cancer treatment time
In terms of dosimetric accuracy, volumetric-modulated arc therapy (VMAT) is comparable to step-and-shoot intensity-modulated radiation therapy (IMRT), but VMAT cuts treatment time considerably, according to research from Memorial Sloan-Kettering Cancer Center.

Breast IMRT without the overspill
An alternative intensity-modulated radiation therapy (IMRT) planning approach spares healthy structures from small, but significant, levels of radiation. IMRT has been recognized as a promising way to prevent breast cancer recurrence in patients who have opted for conservative surgery. Researchers in Alabama have devised a beam arrangement that delivers the benefits of IMRT, but without upping the low-dose overspill.

Good vibrations stave off blood-borne diseases
A therapy based on pulsed laser irradiation could selectively destroy viruses and bacteria without damaging healthy cells. Researchers from Arizona State University in Tempe asked what would happen if viruses and harmful bacteria were excited in the same manner by a pulsed laser. Could the unwanted micro-organisms be forced to shake themselves to pieces without harming useful cells?

Ultrasound nonmass breast lesion features may signal malignancy
By Amerigo Allegretto
Some nonmass breast lesion characteristics on ultrasound exams can be considered suspicious for malignancy at screening ultrasound.
November 5, 2024
Images depict a 43-year-old woman with a malignant non-mass lesion that was diagnosed as microinvasive ductal carcinoma. (A) Transverse and (B) longitudinal ultrasound images show a hypoechoic non-mass lesion (solid arrows) with segmental distribution in the left breast. The lesion has associated calcifications (dashed arrows in A). (C) Longitudinal color Doppler ultrasound image shows high vascularity. (D) Magnified image in the mediolateral oblique view from screening mammography shows grouped calcifications (arrows), which are considered a mammographic correlate of the ultrasound-detected non-mass lesion (A radiopaque marker attached to the skin is visible in the image because the mammographic exam was performed after screening breast ultrasound). Ultrasound-guided core needle biopsy and pathologic examination revealed ductal carcinoma in situ, but the lesion was upgraded to microinvasive ductal carcinoma at subsequent surgery (2.5-cm ductal carcinoma in situ, histologic grade II, estrogen receptor-positive, progesterone receptor-positive, human epidermal growth factor receptor type 2-negative).
