At Shanghai Jiao Tong University School of Medicine's Ruijin Hospital Proton Therapy Center, we turn hope into reality for complex cancer cases.
The Challenge: Mr. Xu, a 70-year-old former oil worker, was diagnosed with locally advanced lung cancer. His age, long history of smoking, and multiple comorbidities like hypertension made traditional treatments a high-risk option for his family.

The Precision Solution: Our multidisciplinary team recommended a radical treatment plan combining chemotherapy and immunotherapy, with a key innovation: Proton Beam Therapy.
Why Proton Therapy? Unlike conventional radiotherapy, proton therapy acts like a "guided missile." It delivers maximum radiation energy precisely at the tumor site (the Bragg Peak effect) while minimizing damage to surrounding healthy tissues like the heart and lungs. This translates to higher tumor control with significantly fewer side effects—a crucial advantage for elderly patients or those with existing health conditions.


The Result: Mr. Xu completed his proton therapy course from July to August 2024 with only mild side effects. By October, follow-up scans showed significant tumor shrinkage. Today, he is full of energy, enjoying his retirement by gardening, walking, and spending time with his grandson.

Advanced age and complex health issues should not preclude effective cancer treatment. At Ruijin Hospital, we leverage cutting-edge proton therapy to offer safer, more precise options, helping patients like Mr. Xu not just survive, but thrive.
