マイクロ超音波ガイド下焦点的レーザーアブレーションによる中リスク前立腺癌の治療：安全性と有効性 (MicroUSgFLA)
中間リスク前立腺がんの治療におけるマイクロ超音波ガイド下焦点的レーザーアブレーション（MicroUSgFLA）治療：安全性と有効性の評価
This clinical research study is intended to show that Micro-Ultrasound Guided Focal Laser Ablation (MicroUSgFLA) is a safe procedure that can significantly postpone or eliminate the need for patients with intermediate-Risk prostate cancer (PCa) to undergo a definitive treatment (i.e., Radical Prostatectomy or Radiation Therapy) for their disease.
調査の概要
状態
詳細な説明
Prostate cancer is the most common cancer in men, and a large proportion of these diagnoses are of the low or intermediate risk type that are amenable to a minimally invasive approach to treatment such as Focal Therapy. If successful, this study will show that trans-perineal interstitial laser focal therapy of the prostate could be offered over a wider community setting than only at a major hospital as an Magnetic Resonance Imaging (MRI), to confidently locate the Index Lesion would not be required because MicroUS is showing the same potential to visualize the lesion. MicroUS-guided focal laser ablation would be a simpler treatment than the complexity required under MRI, it could be offered in communities that might not have local access to MRI facilities and could be offered to individuals who are contra-indicated for MRI for such reasons as having metallic implants or severe claustrophobia.
