The future of focal therapy for prostate cancer treatment

4 min

The outcomes for patients diagnosed with prostate cancer depend on more than just rates of cure or survival. A considerable burden is experienced by men who require treatment for prostate cancer, in many cases arising from complications of the procedures themselves.

The Impact of Prostate Cancer Treatment

Many men who undergo surgery or radiation therapy have worse urinary, bowel (respectively), and erectile function after treatment than they did before1, which can have a substantial negative effect on their mental health2. Refinement of treatment approaches to prostate cancer has drastically improved survival over the past 20-30 years, but this has come with the cost of long-term morbidity for many men.

Some innovations in prostate cancer care during this time have had little if any, effect on postoperative complications (including the use of robotics3).

With advanced medical imaging techniques, such as multiparametric MRI4, specific targeting of prostate cancer tumours has become possible.

Focal Therapy: A Potential Solution

Focal therapy, in which targeted ablation of only cancerous tissue is achieved (using, for example, high-intensity focused ultrasound, cryotherapy, or laser), offers the possibility of good outcomes in terms of metastasis- and cancer-free survival, and avoidance of treatment complications, in men with low or intermediate stage localised prostate cancer.

The Future of Prostate Cancer Care

Unfortunately, there are currently no data available from randomised trials of focal therapy versus prostatectomy to guide practice; these will come soon, from at least three prospective clinical trials. Until then, patients should be encouraged by the continuing advances in prostate cancer treatment, and the potential of good long-term treatment outcomes from the point of view of survival and quality of life.
