Optical Diagnostic Device Can Diagnose Prostate Cancer in Minutes

Optical Diagnostic Device Can Diagnose Prostate Cancer in Minutes
Eager attendees of the upcoming COMPAMED trade fair in Düsseldorf this week, Wednesday, November 12 - 14, will have an opportunity to witness a demonstration of a groundbreaking medical device that can assist physicians dealing with prostate cancer in identifying a benign prostate tissue change from a more concerning malignancy. The company behind this novel diagnostic device is Europe's largest application-oriented research organization, Fraunhofer, who claims it can distinguish between the two types of tissue alterations within a minute-and-a-half via an integrated visual analysis of a biopsy. Operating the device is simple enough. After obtaining a biopsy of the prostate tissue, clinicians simply place it on a base plate and slide it into the machine before pressing a button to allow the device to study the sample. The use of this optical diagnostic device allows for an accurate and speedy analysis without needing a pair of trained eyes, or a long wait, which can cause undue stress and anxiety on the patient's part. In less than 2 minutes, the doctor can immediately sit down with the patient to discuss the results and a plan of action. The device works by directing a laser pulse at the tissue sample, which temporarily excites fluorescent molecules called, "fluorophores". The emitted fluorescence decreases at a rate that varies between a benign or malignant sample. If the rate is above a set threshold, the sample is positive for cancer cells, and will activate a red light on the device, as opposed to a green light for a benign reading. The prototype measures 21 x 24 x 17 inches and has completed 2 clinical trials, with a third currently ongoing. This is not the first diagnostic device to be created specifically for prostate cancer, however. Another
