Clinical Laserthermia Systems

The multicenter study, named the IRMPROFT Study, aims to investigate the "Performance of Prostate MRI and targeted biopsy to detect residual Prostate cancer following focal therapy". Various focal therapy technologies are being used at the different study sites, and Urolib in Besançon has selected the CE-marked and FDA 510(k) cleared CLS TRANBERG® Thermal Therapy system as its focal therapy of choice.

According to the agreement, Urolib purchases the accessories and disposables needed for treatment and CLS provides technical and clinical support.

"We are pleased to have safely treated the first localized prostate cancer patient in France with the CLS TRANBERG system providing temperature controlled focal laser ablation (FLA). Using Ultrasound-fusion for image guidance, we were able to position the Laser Applicator of the TRANBERG system exactly as planned", says Dr Pierre-Charles Henry, one of the principal investigators for Urolib.

"During the laser ablation procedure, the Temperature Probes of the TRANBERG System allowed us to continuously monitor the tissue temperature in real-time, providing important information to optimize the treatment while sparing surrounding tissue. We look forward to enrolling more patients in this nationwide clinical study investigating the accuracy of biopsies after treatment with focal therapy", says Dr Henry.

"Urolib has impressive experience in focal therapy, including FLA, and we are very proud that this centre has chosen to use the CLS TRANBERG system for treatment in this study", says Perjan Pleunis, VP Sales Europe, CLS. "The principal investigators of Urolib, urologists Dr. Vincent Bailly and Dr. Pierre-Charles Henry, also have an extensive experience in MRI-Ultrasound fused biopsy techniques that work well together with the CLS products", says Perjan Pleunis.

About localized prostate cancer

About 1.400.000 new cases per year of prostate cancer are reported worldwide with approximately 350.000 of them within EU. Although there are many prostate cancer treatment options, there is still an important unmet need for patients with localized prostate cancer who progress to intermediate risk stage. The currently available surgical options show significant risks and side effects related to urinary and erectile functions and quality of life.
