Focal Laser Thermal Therapy (FLTT) can be considered the middle ground between radical therapy (prostatectomy surgery) and active surveillance. By targeting only the tumour, focal therapy offers oncologic control without the lifestyle altering side effects of radical, whole gland therapy.
Focal Laser Thermal Therapy (FLTT) is a minimally-invasive surgical prodcedure that uses a laser to heat the tumour to a temperature where it can no longer survive. During the procedure, the laser fibre is inserted through the perineum (the region between the testis and the anus) into the tumour guided by imaging such as ultrasound or MRI. The method has the advantage of real time monitoring during the procedure allowing the temperature of the tissue to be monitored by doctors to ensure that therapeutic temperatures (temperatures at which the tumour cells will not be able to survive) are reached in the target, and that critical structures - such as the urethra and nerve bundles responsible for sexual activity - remain cool and undamaged.
Preliminary data suggests minimal to no complications and no impact on sexual or urinary function as a result of focal laser ablation.
FLTT offers a number of advantages over other therapies:
