放射治療是治療早期非轉移性前列腺癌的方法之一。隨著醫學進步,現今的放射治療變得更精準,更有效根治前列腺癌。 傳統放射治療使用電腦掃描器定位腫瘤,並用高劑量X光照射腫瘤,但影像解像度較低,可能傷及附近腫瘤正常的細胞。現代的磁共振導航影像技術則提高了影像質量,使醫生能更清楚地觀察腫瘤及周圍組織,減低附近正常組織的風險。 新興的治療方法還包括立體定向放射治療和質子治療。立體定向放射治療的治療劑量較高出傳統技術高,因此能顯著減少治療次數。質子治療則透過質子精確投射高劑量射線,將副作用降至最低。 [#CUHKUrology] 🩺#WhattheDoctorSaid: Latest Advancement of Radiation Therapy for Prostate Cancer Radiation therapy is one of the methods for treating early-stage prostate cancer. With advancements in medicine, today’s radiation therapy has become more precise and effective. Traditional radiation therapy uses computer tomography to locate the tumor and irradiates it with high radiation dose. However, because of the low resolution of the image, normal tissues or cells near the tumor may be inadvertently involved. Modern MRI-guided imaging technology improves image quality, allowing doctors to better observe the tumor and surrounding tissues, reducing the risk to harming nearby normal tissues. Emerging treatment methods also include stereotactic radiation therapy and proton therapy. Stereotactic radiation therapy delivers higher radiation dose than traditional techniques, significantly reducing the number of treatments needed. Proton therapy, on the other hand, uses protons to precisely target the tumor with high doses of radiation, minimizing side effects. #醫生話你知 #前列腺癌 #放射治療 #立體定向放射治療 #質子治療 #WhattheDoctorSaid #ProstateCancer #RadiationTherapy #StereotacticRadiationTherapy #ProtonTherapy ----------------------------------------------------------------- 「探泌」CUHK Urology : https://urologycentre.com.hk/ Instagram: / cuhk.urology X: https://x.com/CuhkUrology
