精准放疗为膀胱癌治疗提供“新选项”

Core Viewpoint - The emergence of precision radiotherapy offers a new treatment option for bladder cancer patients, allowing for effective tumor eradication while preserving bladder function and improving quality of life [1][2]. Group 1: Treatment Options - Traditional treatment for bladder cancer involved either complete bladder removal or conservative treatment with high recurrence risks, presenting a significant dilemma for patients [1]. - Precision radiotherapy acts as an "invisible scalpel," effectively targeting tumors while maintaining normal urinary function, particularly beneficial for elderly or frail patients [1]. Group 2: Precision Radiotherapy Advantages - Precision radiotherapy utilizes advanced imaging technologies such as CT, MRI, and PET-CT for real-time tumor visualization, allowing for precise targeting of the treatment area [2]. - The technique employs advanced methods like IMRT and VMAT to ensure that radiation doses are tailored to the tumor shape, minimizing exposure to surrounding healthy tissues [2]. - Image-guided radiation therapy (IGRT) is implemented to correct for any movement during treatment, ensuring accurate delivery of radiation [2]. Group 3: Impact on Patient Care - The shift from a "one-size-fits-all" approach to a "precision preservation" strategy in bladder cancer treatment reflects advancements in technology and a focus on patient dignity and quality of life [2].
