烟台毓璜顶医院放疗科在烟威地区率先开展后装插植放疗技术

Core Viewpoint - The introduction of the afterloading brachytherapy technology at Yantai Yuhuangding Hospital marks a significant advancement in the field of tumor precision treatment, filling a gap in the Yantai-Weihai region and demonstrating the hospital's commitment to innovative medical technology and patient-centered care [1][2]. Group 1: Technology Overview - Afterloading brachytherapy is described as a "precision surgical knife" in tumor treatment, utilizing advanced imaging guidance (CT/MRI) to accurately implant the source within the tumor, achieving a "zero-distance" killing effect [2][4]. - The local dose can reach several times that of traditional external radiation, significantly improving tumor control rates while minimizing dosage deviations caused by respiratory movements or positional changes [2][4]. Group 2: Treatment Benefits - The technology features 3D dose sculpting, allowing for personalized irradiation plans tailored to the tumor's specific shape and size, maximizing tumor coverage while protecting normal tissues [4]. - This method shortens treatment cycles, reduces the risk of tumor cell proliferation during treatment, and does not require the patient to carry a radiation source, thus minimizing hospital stays and treatment costs [4][5]. Group 3: Case Studies - A patient with kidney cancer and bone metastasis received afterloading brachytherapy combined with targeted therapy, resulting in effective tumor control and significant pain relief after treatment [5][6]. - Another case involved a cervical cancer patient where the combined external radiation and afterloading brachytherapy approach allowed for precise targeting of the tumor while protecting surrounding organs, showcasing the technology's effectiveness in complex anatomical structures [7]. Group 4: Future Plans - Yantai Yuhuangding Hospital plans to expand the clinical application of afterloading brachytherapy to include more tumor types, such as breast cancer and soft tissue sarcomas, aiming to benefit a larger patient population [7].
