New Approaches to Early Prostate Cancer

Men today diagnosed with early prostate cancer, Gleason Stage 7 or less, have the option of a new arm of care called watchful waiting. With periodic PSA blood tests, prostate biopsies and imaging studies; urologists and oncologists can follow the patient with disease felt to be not aggressive rather than radiate the lesion or surgically remove it as was done in the past. In some cases, they can watch it even closer with an approach called Active Surveillance. This week a new research treatment was made public.

MedPage Today published work by Steve Raman, M.D., of the UCLA Medical Center on his TULSA-PRO ablation clinical trial. One hundred-fifteen men with localized and low, or intermediate, risk prostate cancer underwent ultrasound blasting of the cancer using the MRI imaging equipment to direct the therapy. In his study, prostate volume decreased from 39 cubic centimeters before treatment down to 3.8 cubic centimeters after a year. Clinically significant cancer was eliminated in 80% of the study participants and 65% had no evidence of cancer after biopsy at one year. PSA blood levels decreased by 95%. The side effects were minimal with low rates of incontinence and impotence and few bowel complications.

The study leader noted that if prostate cancer reoccurred then the modalities of repeat ultrasound treatment, surgery or radiation were still possible. In August 2019, the FDA approved the TULSA-PRO Device for use. The procedure involves placing a rod-shaped device into the urethra. The device has ten ultrasound probes which are controlled by a computer program while the patient is observed in an MRI machine. The probes shoot out sound waves that heat and destroy the tissue the sound is directed at. The procedure is an outpatient procedure which can also be used to shrink a non-cancerous enlarged prostate from benign prostatic hypertrophy.
