More Precise Tumor Treatment: Hygeia Chang An Hospital Adopts Spatially Fractionated Radiation Therapy

Recently, the Radiation Therapy Center of Hygeia Chang An Hospital Cancer Hospital has successfully implemented Spatially Fractionated Radiation Therapy (SFRT), benefiting multiple patients with complex tumors. For large‑volume, irregular, refractory recurrent tumors, tumors at special locations adjacent to vital organs and advanced‑stage cancers, this innovative technique can better destroy lesions while safeguarding critical organs. It enables personalized and precise treatment and improves patients’ tolerance and quality of life.

For tumors of large size or special locations, conventional radiotherapy has limited flexibility in adjusting radiation doses. Excess radiation may harm surrounding tissues and organs when controlling tumors, whereas insufficient doses fail to kill cancer cells. According to Professor Cui Lichun, Executive Dean of Chang An Hospital Cancer Hospital, SFRT works much like “precision sculpting”. The tumor lesion is divided into grid‑like zones with alternating high‑dose peaks and low‑dose valleys. High doses are delivered to core tumor regions for intensive destruction; marginal tumor areas receive low doses for moderate control; adjacent healthy tissues and organs get key protection.

“It is similar to precision irrigation for farmland: water more in drought‑stricken areas, less in damp zones, and avoid watering areas that need none,” Professor Cui Lichun explained. Featuring “peak‑valley matching, zoned management and precision targeting”, SFRT delivers solid therapeutic outcomes with fewer side effects, fewer treatment sessions and shorter treatment cycles.

Equipped with a full array of precise radiotherapy devices including the GyroKnife for high‑dose focused radiation, linear accelerators for fine low‑dose control, and TOMO helical tomotherapy systems, Chang An Hospital Cancer Hospital meets hardware requirements for mixed high‑and‑low‑dose delivery. A special SFRT team consisting of senior clinicians, medical physicists and technicians designs highly individualized treatment plans for each patient. Strict quality control covers positioning, target delineation, dose fractionation and plan evaluation. Nutritional support, pain management and psychological intervention are provided to deliver integrated care combining therapy and humanistic support.

Committed to patient‑centered care, the Radiation Therapy Center of Chang An Hospital Cancer Hospital devotes itself to precise oncology diagnosis and personalized radiotherapy. The launch of SFRT marks a major technical breakthrough and embodies its patient‑first philosophy. With continuous optimization of this technology, higher‑quality medical services will be accessible to more patients.
