Radiation photodynamics is a new method of tumor treatment that takes advantage of the difference in affinity and metabolic rate of photosensitizers between tumor cells and normal cells, which is absorbed by tumor lesions after patients take photosensitizers orally, and then irradiated by low-dose high-energy X-rays emitted by cyclotron to produce sufficient amount of oxygen radicals in tumor lesions to kill cancer cells anywhere in the body through molecular targeting. This advanced technology can be imaginatively called “photonic missile”, which is guided and detonated by photosensitive drugs to kill and remove cancer cells in a targeted, accurate and effective manner. This technology has achieved remarkable results in the treatment of advanced cancer patients with recurrence, spread, and multiple metastases! Advantages and characteristics of radiophotodynamic: 1. Systemic: It brings hope for life to patients with advanced tumors who are helpless to conventional treatment after spreading throughout the body. 2.It has the basic effects of X-ray radiotherapy and photodynamic therapy. 3.Good killing effect on cancer cells: molecular targets act on the starting point of apoptosis and necrosis program of tumor cells, which can rapidly lead to the death of tumor cells. The effective rate is over 90%. 4.Good targeting: it has the molecular targeting effect and the characteristics of targeted drugs, with strong affinity to cancer cells and no toxic effect to surrounding normal cells. 5.Solve the cancer treatment problem that conventional radiotherapy is not sensitive to cancer cells with lack of oxygen. 6.Solve the problem of low absorption of ischemic chemotherapy drugs in tumor lesions: 4 hours after taking the drug, each time local fit treatment, the amount of X-ray radiation is in 5-8GY, even if the drug concentration is reduced by 100 times, sufficient oxygen radicals can be obtained. 7.Effective for both local and systemic lesions: Since it has the systemic effect of drug therapy (chemotherapy) and the local effect of radiation therapy (radiotherapy) at the same time, the advantages of the two therapeutic effects are brought into full play, and the effect of 1+1 is greater than 2 is achieved. 8.Low side effects: Using oral amino acids as a means of synthesizing photosensitizers in vivo, amino acids themselves are non-toxic and do not have the systemic toxic effects of chemotherapy drugs. It can also be applied to the old and frail people. 9.Advanced localization technology: The most advanced tumor target localization technology-PET/CT or PET/MR is used. 10.Wide indications: It can treat most of the middle and late stage malignant tumors in the whole body.
