(Delivering Hope with Radiation, Protecting Lives with Expertise)

I. Department Overview and Positioning

• Department Nature:​ Department of Radiation Oncology III is a clinical specialty department that utilizes carbon ion beams for precise radiotherapy of malignant tumors. It represents the pinnacle of current technology in the field of radiation oncology, serving as a model for the deep integration of radiation physics, radiation biology, and clinical oncology.

• Development History:​ The department was established in July 2025 and has successfully treated 52 patients.

• Core Values:​ Excellence, Collaboration, Patient-first.

II. Talent Team and Discipline Structure

• Team Size:​ Employs 13 medical staff, including 1 senior title holder and 5 junior title holders.

• Core Expert:​ Zhang Yingdong, Chief Physician, Director of the Lanzhou Heavy Ion Radiation Oncology Department III. Former Administrative Head of the Radiation Oncology Department at Peking University International Hospital, Director of the Radiation Oncology Center at Capital Medical University Sanbo Brain Hospital, and postgraduate in Radiation Oncology at Peking University Third Hospital. Committee Member of the Radiation Therapy Committee of the Bethune Charitable Foundation; Member of the Central Nervous System Tumor Radiotherapy Group of the Radiation Oncologist Branch of the Chinese Medical Doctor Association; Member of the Tumor Radiotherapy Committee of the Beijing Anti-Cancer Association; Member of the Head and Neck Tumor MDT Committee of the Beijing Cancer Prevention and Control Society. With over 30 years of experience in radiation oncology, he specializes in radiotherapy for malignancies of the central nervous system, head and neck, chest, abdomen, pelvis, and limbs, and has in-depth research into combined therapies such as chemotherapy, targeted therapy, and immunotherapy during radiotherapy. Proficient in developing individualized comprehensive treatment plans based on different patient conditions. Possesses extensive clinical experience and profound academic accomplishments, with multiple papers published in authoritative journals such as Cancer Cell International, Chinese Journal of Radiation Oncology, and China Oncology.

•Talent Structure:​ 6 department members hold master's degrees; 6 physicians are aged between 25 and 50.

• Nursing Team:​ A dynamic and passionate nursing team of 7 members, including 1 head nurse and 6 nurses. Adhering to the principle of "patient-centered, thinking what patients think," they are dedicated to providing scientific, precise, and humane care for each patient.

III. Scope of Services and Technical Features

• Main Services:​ The department conducts advanced radiotherapy including heavy ion therapy and photon therapy (3D-CRT, IMRT, IGRT, VMAT, SBRT), alongside mainstream oncology treatments such as chemotherapy, targeted therapy, and immunotherapy. It focuses on heavy ion therapy and photon-based 3D conformal and intensity-modulated radiotherapy for head, neck, and pelvic tumors. Characteristic specialties include over 50 types of solid tumors such as glioma, chordoma, adenoid cystic carcinoma, oral cancer, oropharyngeal cancer, prostate cancer, rectal cancer, and soft tissue sarcoma.

• Core Technologies:

(1) Heavy Ion Therapy: Targeted 'Surgical Strike' on TumorsHeavy ion therapy is one of the most advanced radiotherapy technologies globally, renowned as a "sharp tool against cancer." The Heavy Ion Radiotherapy Center at the Gansu Wuwei Cancer Hospital Lanzhou Campus is a leading domestic base for heavy ion therapy, equipped with internationally advanced heavy ion medical devices.

(2) Photon Radiotherapy: A radiotherapy technique that uses high-energy X-rays or gamma rays to treat tumors, representing one of the most widely used radiotherapy methods. It employs a linear accelerator to generate high-energy photon beams directed at the tumor site to damage tumor cell DNA, thereby inhibiting tumor growth or killing tumor cells.

IV. Hardware Facilities and Research Platform

• Advanced Equipment:​ We possess a domestic carbon ion therapy system that uses accelerated carbon ion beams to precisely target tumors.

• Precise 'Stereotactic Strike':​ When carbon ion beams penetrate human tissue, they deposit less energy initially. Upon reaching the predetermined tumor site (end of range), they release almost all their energy instantaneously, forming a dose distribution known as the "Bragg Peak." By precisely controlling the energy, this peak can be made to accurately cover the tumor, acting like a scalpel to eradicate the tumor while maximally protecting surrounding normal tissues and critical organs.

• Powerful Tumor Cell Destruction:​ Unlike conventional radiotherapy (e.g., X-rays, gamma rays) that primarily cause DNA single-strand breaks, carbon ion beams can directly cause DNA double-strand breaks in tumor cells. This type of damage is difficult to repair, resulting in more thorough cancer cell kill and helping to prevent recurrence. Furthermore, carbon ion therapy is effective regardless of oxygen concentration, making it effective even against hypoxic tumor cells, which are often the source of recurrence after conventional radiotherapy.

• Better Patient Experience:​ Due to its precision and potency, carbon ion therapy typically has fewer side effects. Many patients experience no or minimal pain or discomfort during treatment, and the treatment cycle may be shorter, enhancing the patient's treatment experience and quality of life.

• Research Platform:​ Given its cutting-edge nature, the Carbon Ion Radiotherapy Department often serves as a source for clinical research and new technologies, continuously conducting studies on radiobiological effects, exploration of new indications, and optimization of treatment techniques.

• Education and Training:​ Bears the important task of training professionals (physicians, physicists, technicians) in the field of heavy ion radiotherapy, serving as a high ground for continuing medical education.

V. Service Philosophy and Patient Care

We guard life with precise technology and warm the soul with humane care, providing individualized and dignified diagnostic and therapeutic services for each patient. We treat not just the tumor, but the personwith the tumor. We care about your physical, psychological, social, and spiritual needs. Your safety is our lifeline. We ensure the safety and effectiveness of treatment through the establishment of a stringent quality control system.
