Oncology Imaging

 

A retrospective analysis of National Lung Screening Trial (NLST) exams has shown that most lung cancers that were detected within a year after a negative CT screening exam—some 40 of 44, or 91 percent—were present but overlooked at the screening. 

PET/CT can add value to cancer staging and follow-up in pediatric patients. In fact, it may come to play an important role in directing image-guided biopsies of children, according to a study published online Dec. 27 in the American Journal of Roentgenology.

A retrospective study published in the American Journal of Roentgenology determined that CT is a useful tool for staging colon cancers that have moved beyond the bowel wall. While performance suffers in certain situations, the largely Dutch authors recommend using thin-slice CT to detect cancers.

 

Radiologists who interpret oncologic imaging exams but don’t participate in multidisciplinary tumor boards (MTBs) miss a golden opportunity to show their value to clinicians, patients and provider systems. 

Researchers from Brown University touted the efficacy of tumor ablation in treating small-cell lung cancer, publishing their results in the Journal of Vascular and Interventional Radiology.

Prostate cancer patients keep options open with MRI-guided interventions

MRI-guided prostate interventions appear to have a bright future combining with the latest and greatest radiation therapy techniques to make prostatectomy and no therapy at all the least attractive options for most men with low-to-intermediate-grade prostate cancer. 

ASTRO: Upped-dose radiation regimen maintains high quality of life for busy prostate cancer patients

BOSTON—Compared with conventional radiation therapy (RT), larger-dose RT delivered over a shorter period—called hypofractionated RT—has previously proven just as efficacious for treating low-risk, early-stage prostate cancer. Now researchers have further shown that, despite the increased doses, hypofractionated treatments do no clinically significant harm to these patients’ quality of life (QOL). 

ASTRO: Many lung cancers stand little chance against stereotactic body radiation therapy—and conventional radiotherapy’s days are numbered too

BOSTON—Stereotactic body radiation therapy (SBRC) has beaten the pants off conventional radiation therapy in the Veterans Health Administration, significantly boosting both overall and lung cancer-specific survival in thousands of patients with stage I non-small cell lung cancer (NSCLC) in the first decade of the 21st century. 

ASTRO: Targeted radiation cuts local recurrence of brain metastases, but other outcomes measures not as impressive

BOSTON—If given the chance to choose between two recurrence-busting radiotherapy methods, many patients who have had a metastatic tumor resected from their brain would likely choose finely targeted stereotactic radiosurgery (SRS) applied only to the surgical bed of the resected lesion over radiation therapy applied to the entire brain. 

ASTRO president outlines plan for greater patient safety, more ‘moonshot’ involvement

Helping radiation oncologists learn from their own medical errors, adopt standardized best practices and participate more prominently in the Obama administration’s “cancer moonshot”: Those three areas of activity currently top the priority list of the American Society for Radiation Oncology (ASTRO).
