Screening for Prevention vs. Early Detection | Response to JAMA Article

The July 29, 2013 edition of the Journal of the American Medical Association (JAMA) includes an opinion piece titled, “Over diagnoses and treatment of cancer? An opportunity for improvement.”  The authors highlight the growing body of literature and a growing depth of understanding as it relates to cancer prevention and early detection. They call for an open dialogue between patients and the medical community. Fight Colorectal Cancer couldn’t resist weighing in on this issue. Colorectal cancer is a “Crown Jewel” of cancer screening The article (which can be read in full here) discusses what we’ve learned from data about cancer incidence (number of diagnoses) and cancer mortality (number of deaths). 

Should All Colorectal Tumors Be Tested for Lynch Syndrome?

An international study described in the Oct. 17 Journal of the American Medical Association (JAMA) found that universal tumor testing in all newly diagnosed colorectal patients produced a “modest increase” in finding people with Lynch syndrome. One in every 35 people with colorectal cancer has Lynch syndrome – an inherited genetic mutation which greatly increases the person’s chance of developing colorectal cancer more than once, plus other cancers (stomach, pancreas, urinary system, brain or skin cancers). Women with Lynch syndrome also face a 40-60 percent chance of developing endometrial (uterine) cancer in their lifetime and an increased risk for ovarian cancer. Until genetic tests of tumors became available in recent

Allergic Reactions to X-Ray Contrast Can Be Treated without Long Term Problems

Occasionally people having CT scans or other imaging exams will have an allergic-type reaction to the iodine contrast, but research has found that they can be treated safely without long term effects. In fact, almost all reactions are mild and more han 99 percent patients with them will get better within a day. Radiologists at the University of Michigan hospitals in Ann Arbor studied nearly 85,000 intravenous injections of nonionic iodinated contrast media looking for allergic-type reactions.  They analyzed both how the reactions were treated and whether there were any long term problems after a reaction.

Milk as Good as Barium Drink in CT-Scans

Simple whole milk may be as effective in barium drinks to distend and outline the intestinal tract so it can be clearly seen during a CT scan. Radiologists at Columbia University randomly gave patients who were having CT scans of their abdomen and pelvis either whole milk or a drink containing barium (VoLumen).  In addition, intravenous contrast was used to enhance images.
