Targeted Microwave Tissue Coagulation for Prostate Cancer

This clinical trial is to provide a minimally invasive treatment option in which the targeted prostate cancer tissue is killed by microwave only in the specific area of cancer "that should be treated for saving of life," while leaving a portion of the normal prostate tissue that is not cancerous. This treatment is named "focal therapy" for "clinically localized prostate cancer." As this new treatment aims to treat only the specific prostatic area of cancer, it is different from the invasive conventional treatment to remove the entire prostate gland. The goal is both to control the known cancer by treating only the cancerous area and to maintain the quality of life (QOL) by leaving the other normal prostate tissue and its surrounding organs intact, resulting in the prevention of urinary leakage and sexual dysfunction as complications.
