CLINICAL APPLICATION & CRITERIA

Carbon Ion (Heavy Ion) Therapy in China

Heavy ion therapy represents the pinnacle of precision radiation oncology, accelerating charged carbon ions to approximately 70% the speed of light and delivering them through the Bragg peak effect — depositing maximum energy precisely at the tumor depth with minimal entrance and exit dose. With a relative biological effectiveness two to three times that of photons and protons, carbon ions cause double-strand DNA breaks that cancer cells cannot repair, making them uniquely effective against radioresistant, hypoxic, and recurrent solid tumors. Treatment courses are typically shorter than conventional radiotherapy, with fewer side effects.

  • Higher Relative Biological Effectiveness
  • Bragg Peak Dose Distribution
  • Shortened Treatment Courses
  • Treatment Option for Selected Recurrent Tumors
  • Pediatric Dose-Sparing Potential
  • Personalized Treatment Planning

WHY CHOOSE US

Why Choose China Cancer Help for Carbon Ion Therapy

A specialized clinical continuum connecting international patients directly with China’s National Heavy Ion Radiotherapy Centers.

China has achieved 100% indigenous research, development, and manufacturing of heavy ion accelerator systems — a milestone previously held only by Japan and Germany. The Chinese Academy of Sciences’ Wuwei and Lanzhou systems, along with centers in Shanghai, Hangzhou, Putian, and beyond, form the largest heavy ion expansion globally. The Shanghai Proton and Heavy Ion Center has treated over 15,000 patients, publishing outstanding five-year outcomes: 92.9% overall survival for newly diagnosed nasopharyngeal carcinoma and 100% cause-specific survival for localized prostate cancer.

Treatment costs approximately ¥400,000–600,000 (US6,000–85,000) — significantly less than comparable therapy in Japan, Germany, or the United States. Innovations such as single-cycle energy modulation technology have dramatically improved beam utilization and treatment efficiency. International patients benefit from dedicated multilingual coordinators, medical visa support, and integrated care at internationally accredited centers offering the same treatment quality as leading global facilities at substantially lower cost.

PATIENT FAQS

Frequently Asked Questions

Key clinical, financial, and logistical insights for international Heavy Ion (Carbon Ion) Therapy patients considering care in China.

While protons have a Bragg peak, carbon ions are 12 times heavier, providing both a razor-sharp Bragg peak and a high Linear Energy Transfer (LET). This results in 2 to 3 times higher biological effectiveness (RBE), making carbon ions uniquely potent against radioresistant tumors.
Key indications include bone and soft tissue sarcomas (chordoma, chondrosarcoma, osteosarcoma), mucosal melanoma, adenoid cystic carcinoma of the salivary gland, locally advanced pancreatic cancer, and locally recurrent nasopharyngeal carcinoma.
Treatments are administered at premier centers including the Shanghai Proton and Heavy Ion Center (SPHIC) and the Lanzhou Heavy Ion Hospital (HIMM), which utilize state-of-the-art synchrotrons with 3D pencil beam scanning.
Due to high biological potency, carbon ion therapy is hypofractionated: courses often complete in just 12 to 16 fractions over 3 to 4 weeks, compared to 6 to 8 weeks for standard photon radiation.
