Fluorescence imaging guides prostate biopsies

Prostate biopsies, which are performed if a cancerous tumor is suspected, could become more accurate and reliable thanks to a new fluorescence imaging technique. Leti researchers partnered with academic scientists and an SME to develop a new fluorescent marker coupled with a combined optical-ultrasound probe. The system renders any tumors visible for priority sampling during biopsies.

Currently, a prostate biopsy entails taking around a dozen samples from different areas of the prostate—an invasive procedure that brings with it the risk of complications. The new fluorescence-guided procedure would constitute a major step forward by reducing the number of samples needed to make a reliable diagnosis.
The results of initial preclinical tests have been positive and clinical trials could begin in late 2015.
