Local radiotherapy is an important treatment for lymphoma, but it must be clear that radiotherapy is a local treatment and is only effective for lesions within the irradiation range, but not for lesions outside the irradiation range. Therefore, radiotherapy is only used for early limited lesions and to relieve the compression symptoms of large lesions. In the treatment of nasal extranodal NK/T-cell lymphoma, various radiotherapy, chemotherapy + radiotherapy, chemotherapy + radiotherapy + chemotherapy regimens have been tried, each with its own advantages and disadvantages. Based on our clinical practice of treating hundreds of patients in recent years, we suggest that for early nasal type extra-nodal NK/T-cell lymphoma, combined chemotherapy followed by radiotherapy in the affected field is a more appropriate plan, and the dose of local radiotherapy should be in the range of 50~-55GY. On the one hand, chemotherapy first can reduce the tumor load as soon as possible and remove the microscopic lesions that are difficult to be detected by existing imaging. On one hand, chemotherapy first can reduce the tumor load as soon as possible and remove the microscopic lesions that are difficult to be detected by existing imaging, making the lesions more limited; on the other hand, it can also reduce the risk of local tissue damage caused by radiotherapy first, resulting in serious infection during subsequent chemotherapy.
