“Screening for cancer has the potential for intended beneficial effects, with the reduction on cancer mortality as the most important. Inevitably, however, screening for cancer also has unintended harmful effects.”

— Authors of a Danish study on the psychological effects of false-positive results in screening mammograms

I’m especially looking forward to the symposium on renal denervation at the Society of Interventional Radiology’s annual meeting next month. The session—featuring presentations from Hicham Abada, MD; Alex Powell, MD; and Marc Sapoval, MD, PhD—will focus on the basics of the pathophysiology of sympathetic overdrive in hypertension and other cardiovascular disease, discuss the anatomical limitations of renal denervation, and discuss technical approaches to the procedure.

Read more about the topic in this month’s E-News Exclusive.

If you're in New Orleans for the meeting, stop by booth 1014 to chat about what you see as important and interesting at SIR 2013.

SIR to Host Balanced Look at Renal Denervation
By Jim Knaub

Using a catheter to deliver radio-frequency energy to nerves in the kidneys to help control blood pressure is intriguing. Renal denervation could provide an effective treatment for people with high blood pressure who don’t respond to medical therapy, and up to one-third of patients with hypertension may be resistant to medical therapy, according to a study by Michael Doumas, MD, published in the International Journal of Hypertension. The procedure is involved in trials in the United States and around the world to investigate the treatment.

Renal denervation utilizes a catheter introduced through the femoral artery and then maneuvered into the renal artery. Once the catheter tip is in place within the artery, low radio-frequency energy is applied to the nearby renal nerves and reduces the hyperactivation of the sympathetic nervous system, which is an established contributor to chronic hypertension. Each kidney is treated in the procedure.

Some think it eventually could provide a minimally invasive, cost-effective alternative to medical therapy—but that’s getting ahead of things.

SNMMI Launches Dose Optimization Resource
SNMMI is offering a new tool to help imagers select and use the proper dose for all nuclear medicine procedures. The information, available here, is designed to help ensure patients receive the smallest possible amount of radiopharmaceutical that will provide the appropriate diagnostic information.

Medicare Plans to Ease Data Collection Requirement
for PET Coverage for Cancer
The Centers for Medicare & Medicaid Services plans to cover FDG-PET scans for monitoring most cancers without the current requirement for prospective data collection by the National Oncologic PET Registry, according to a proposed decision memo. A notable exclusion to the coverage would be prostate cancer.

Study: For Most Women, Mammography Every Other Year Is OK
A new study published in JAMA Internal Medicine reports that most women can have mammograms every other year instead of annually with a similar risk of finding advance stage cancer at screening. Women with extremely dense breast tissue are an exception and still benefitted from annual screening in the study.

Research Finds Long-Lasting Stress From Mammo False-Positive
Women who receive a false-positive result on a mammogram report experienced psychological stress three years after the test and follow-up care, according to a Danish study published in American Family Medicine and also reported by ABC News.
