Addition and subtraction of postoperative radiotherapy for breast cancer in the era of precision medicine / 肿瘤

ABSTRACT

Radiotherapy plays an important role in the current treatment of breast cancer, which can greatly reduce the local recurrence rate of breast cancer patients. In recent years, many clinical trials on the radiotherapy of breast cancer have shown that the benefits of radiotherapy are different in breast cancer patients with different molecular typing, lymph node metastasis, surgical resection methods, and so on. Therefore, in the era of precision medicine, the radiotherapy of breast cancer needs to be based on the clinical treatment guidelines and clinical evidence, and in combined with the actual situation. The precise radiotherapy should be carried out according to the assessment results of individual recurrence risk, so as to maximize the benefit of patients through reducing the recurrence rate and avoiding excessive treatment. In this paper, the current research progress in the post-operative radiotherapy based on the molecular classification of breast cancer, lymph node metastasis and surgical resection methods is summarized, in order to provide the clinical basis of postoperative precise radiotherapy for breast cancer patients.
