Ultrasound motion tracking for radiation therapy.

CONCLUSION: It is not clear whether ultrasound motion tracking will become established in the clinical routine although all technical prerequisites can be considered as fulfilled, such that exciting progress in this field of research is still to be expected.

Abstract Randomized controlled trials provide evidence-driven clinical decision making in the management of newly diagnosed nonmetastatic and oligometastatic prostate cancer. Advances in technology (eg, multiparametric MRI, MR/transrectal ultrasound fusion biopsy, image-guided radiation therapy, stereotactic body radiation therapy) have transformed diagnosis and treatment of prostate cancer while improving cancer control and quality-of-life outcomes. Exciting breakthroughs are revealing possible new indications for radiotherapy, particularly with respect to oligometastatic prostate cancer. Ongoing studies using ne...

Neither contrast-enhanced computed tomography nor magnetic resonance imaging can monitor changes in the pancreatic ductal adenocarcinoma microenvironment during therapy. We hypothesized that shear wave elastography could overcome this limitation. To test this hypothesis, we measured the shear modulus of two groups of murine pancreatic tumors (KCKO, n  = 30; PAN02, n = 30) treated with stereotactic body radiation therapy (SBRT). The mean shear modulus of KCKO tumors was 7.651 kPa higher than that of PAN02 tumors (p

Conclusion: PSCCT is a rare but aggressive malignancy of the head and neck. Histopathologic and immunohistochemical evaluations are essential for diagnosis. While locoregional surgery and radiation therapy may improve the length of survival, the prognosis of patients with PSCCT is poor. Physicians should be mindful of this unique but deadly disease process, as early diagnosis and rapid treatment initiation are essential to optimize treatment outcomes. PMID: 31528145 [PubMed]

Healthcare systems are often compared with the aviation industry. Progress in both is highly desired but must always be achieved with safety in mind. Everyone wants to get from point A to point B faster and more comfortably, but how much risk of uncertainty is one ready to accept to achieve that extra speed? Both industries also share the aspect of competition for customers. In the field of localized prostate cancer, patients have an ever-increasing choice of options: radical surgery (open vs laparoscopic vs robot-assisted), external beam radiation therapy (EBRT) (with photons or protons), brachytherapy (low-dose rate or h...

ConclusionsInjection of a liquid fiducial marker for esophageal cancer radiation therapy is technically feasible with no adverse events identified. Volumes of>0.05 mL have an appropriate visibility on CT, CBCT, and MRI, with an excellent positional stability. Liquid fiducial markers are therefore promising for use in image guided radiation therapy.

Medical device companies attempting to market a new treatment in the U.S. often make the erroneous assumption that winning FDA approval is the final destination, and success is theirs. In fact, going through the regulatory process is only the halfway point. The grueling path from FDA approval to reimbursement is like a treacherous walk through Death Valley and many companies don’t make it through. In this case study, I discuss the trials and triumphs of bringing robotic high intensity focused ultrasound (HIFU), a non-invasive procedure for localized prostate cancer, to the U.S.&Aci...
