A new technique dealing with prostate cancer has shown astonishing results in a study where 115 men were treated: not only was what the authors termed “clinically significant cancer” totally eliminated in 80% of the subjects when they were examined one year later, 65% of the men showed no evidence of cancer at all, and prostate-specific antigen (PSA), which is used as a chief marker identifying prostate cancer, was reduced by a median of 95%.
The procedure, which was performed for an average of 51 minutes, involves an MRI-guided ultrasound technique called MRI-guided transurethral ultrasound ablation (TULSA). A rod enters the prostate gland through the urethra, then distributes sound waves, carried by 10 heating elements, to heat and destroy diseased tissue; healthy tissue is left untouched. The sound waves are controlled by an algorithm, which decides what the shape, direction and strength of the waves should be.
