Focal therapies for cancer have been around for more than two decades and have been accepted treatment options for breast and renal cancers. Gaining acceptance for prostate cancer, however, has been a long-winding road.
With the growing acceptance of the value of multi-parametric MRI (mpMRI) the detection, diagnosis and treatment of prostate cancer is undergoing a paradigm shift away from biomarkers and standard 12-core biopsies to imaging-based strategies with targeted biopsies.
Since the US Preventive Services Task Force (USPSTF) gave prostate cancer screening a “D” grade in 2012, researchers have been looking for better ways to detect, diagnose and treat prostate cancer. Blood tests such as the PSA and imaging and biopsy tests, however, have lacked specificity, identifying cancer only about half the time, while missing clinically significant cancer.
Good question! If you Google the term “minimally invasive” in relation to any medical treatment, it is likely that you will get a wide range of procedures that claim to fall under this category.
