Advanced Radiation Therapy for Breast Cancer in Shanghai
Radiation therapy is a cornerstone of breast cancer treatment, used after surgery to eliminate residual cancer cells, reduce recurrence risk, and preserve healthy tissue. For international patients seeking the most advanced radiotherapy techniques — including cutting-edge proton therapy — Shanghai's Ruijin Hospital offers world-class expertise led by one of China's most decorated radiation oncologists.
Featured Specialist: Prof. Chen Jiayi (陈佳艺)
Prof. Chen Jiayi is a leading radiation oncologist at Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, specializing in breast cancer radiotherapy and proton therapy. She is the recipient of the prestigious "Guozhi Mingyi · Zhuoyue Jianzhu" Award (国之名医·卓越建树) — one of China's highest honors for outstanding medical achievement.
Prof. Chen is the lead author of the radiotherapy section of the CSCO Breast Cancer Diagnosis and Treatment Guidelines — the national standard followed by oncology centers across China. She is also among the first cohort of Chinese scholars to conduct proton therapy research for breast cancer, placing her at the forefront of next-generation radiation oncology in Asia.
What Is Proton Therapy and Why Does It Matter for Breast Cancer?
Conventional radiation therapy uses X-rays (photons) that deposit energy both before and after reaching the tumor, exposing surrounding healthy tissue — including the heart and lungs — to radiation. Proton therapy delivers a precise dose of radiation that stops exactly at the tumor (the "Bragg peak"), dramatically reducing exposure to adjacent organs.
For breast cancer patients, this distinction is clinically significant:
- Heart protection: Left-sided breast cancer radiation can affect the heart; proton therapy minimizes cardiac dose, reducing long-term cardiovascular risk
- Lung sparing: Reduced lung exposure lowers the risk of radiation pneumonitis and long-term pulmonary fibrosis
- Chest wall precision: Ideal for post-mastectomy radiation where the target is close to critical structures
- Young patients: Lower lifetime radiation exposure is especially important for patients with decades ahead of them
- Re-irradiation: Enables safer retreatment for recurrent breast cancer in previously irradiated fields
Radiotherapy Techniques Available at Ruijin Hospital
- Proton therapy — for eligible patients requiring maximum precision and organ sparing
- Intensity-modulated radiation therapy (IMRT) — highly conformal dose delivery to complex target volumes
- Volumetric modulated arc therapy (VMAT) — faster treatment delivery with excellent dose conformity
- Deep inspiration breath-hold (DIBH) — reduces heart dose for left-sided breast cancer by moving the heart away from the radiation field
- Hypofractionated radiotherapy — fewer, larger daily doses completing treatment in 3–4 weeks instead of 5–6
- Accelerated partial breast irradiation (APBI) — targeted radiation to the tumor bed only, for selected early-stage patients
- Post-mastectomy radiation therapy (PMRT) — chest wall and regional nodal irradiation after mastectomy
Who May Benefit from Proton Therapy for Breast Cancer?
- Patients with left-sided breast cancer where cardiac proximity is a concern
- Young patients for whom minimizing lifetime radiation exposure is a priority
- Patients with underlying heart or lung conditions who cannot tolerate conventional radiation doses to those organs
- Patients requiring post-mastectomy radiation with complex chest wall anatomy
- Patients with locally recurrent breast cancer who have previously received radiation
- Patients with bilateral breast cancer requiring radiation to both sides
The CSCO Guidelines: National Standard, International Quality
The Chinese Society of Clinical Oncology (CSCO) Breast Cancer Guidelines are the authoritative national treatment standards used by oncology centers across China. As the lead author of the radiotherapy section, Prof. Chen Jiayi's clinical protocols represent the current evidence-based standard of care — ensuring that patients treated at Ruijin Hospital receive radiotherapy aligned with the latest international evidence and adapted for Chinese clinical practice.
How CMCS Coordinates Your Radiotherapy Care
China Medical Concierge Shanghai (CMCS) is a health management company — not a hospital. We connect international patients with Shanghai's leading radiation oncologists, including Prof. Chen Jiayi at Ruijin Hospital, and manage the full coordination process:
- Review of existing surgical pathology, imaging, and prior treatment records
- Assessment of proton therapy eligibility based on tumor location, stage, and anatomy
- Appointment scheduling with Prof. Chen's radiation oncology team
- Medical interpretation during simulation, planning consultations, and treatment
- Coordination with breast surgeons and medical oncologists for integrated multidisciplinary care
- Logistics support: accommodation near Ruijin Hospital for the duration of treatment
- Post-treatment follow-up and imaging coordination
