放射治疗是肿瘤的主要治疗手段之一,但有些肿瘤的放射治疗效果并不令人满意,同时放疗后的各种并发症,如盆腔肿瘤放疗后的出血性膀胱炎和直肠炎,头颈部肿瘤放疗后的骨坏死和放射性脑病以及乳腺癌放疗后皮肤坏死等的发生率较高。对于这些问题,尤其是放射性损伤的治疗效果仍然不够理想。 Radiation therapy is one of the main treatments for tumors, but some tumors have unsatisfactory results in radiation therapy, and various complications after radiotherapy, such as hemorrhagic cystitis and proctitis after pelvic tumor radiotherapy, head and neck The incidence of osteonecrosis and radiation encephalopathy after radiotherapy of the tumor and skin necrosis after radiotherapy of breast cancer are high. For these problems, the therapeutic effect of radiation damage, in particular, is still not ideal.
