The study of re-irradiation for head and neck cancer / 中华放射肿瘤学杂志

ABSTRACT

Nearly 50% patients with head and neck cancer after radiotherapy will recurrence in the previous radiation fields.Salvage surgery is the first choice of treatment.Clinical studies have shown that a small number of patients with recurrent head and neck cancer can benefit from salvage surgery plus postoperative re-irradiation or re-irradiation with or without chemotherapy or targeted therapy,and these patients can achieved tumor control and long-term survival.However, the overall efficacy is not satisfactory, and often accompanied by severe acute and late, and even fatal treatment-related toxicity.Therefore, it is necessary to give full consideration to the condition of recurrent tumor, the first radiotherapy related factors and the patient′s related status before implementation of re-irradiation.The development of radiotherapy technology and comprehensive treatment, including the clinical application of proton and heavy ion and immune therapy, provides the possibility of improving the prognosis and reducing treatment-related toxicity for these patients.
