早期乳腺癌新辅助放疗现状与展望

辅助放疗已成为乳腺癌标准治疗的重要组成部分。与传统的术后放疗相比,新辅助放疗具有靶区勾画更准确、优化乳房重建放疗策略、肿瘤降期增加保乳手术机会、提高病理完全缓解率免除乳房手术等理论优势,并被近年来的临床研究所证实。但其最佳的靶区勾画、剂量分割、放疗‐手术间隔时间、与全身治疗的联合应用等仍需前瞻性研究加以明确和优化,以期为早期乳腺癌患者提供最佳的治疗选择。

Updates and prospect of neoadjuvant radiotherapy for early breast cancer

Adjuvant radiotherapy has become an important part of the standard treatment for breast cancer. Compared with the traditional postoperative radiotherapy, neoadjuvant radiotherapy has the theoretical advantages of more accurate target delineation, optimization of radiation strategy for breast reconstruction, increase of breast conservation surgery with tumor down‐staging and avoiding breast surgery by improving pathological complete response rate, which have been confirmed by recent clinical research. Prospective studies are still needed for the optimal target delineation, dose fractionation, radiation‐surgery interval, and combination with systemic therapies, aiming to provide the optimal treatment option for patients with early breast cancer.
