分子生物学和细胞生物学的进展正在加深人们对乳腺癌的了解,并给今后乳腺癌的放疗带来了很大的希望。这两者的研究还会使放疗分级的分子基础及放疗后肿瘤和正常组织的反应变得清晰明朗。在临床应用中,分子生物学和细胞生物学所提供的肿瘤的分子学特征,将帮助患者选择治疗方案。尽管一些研究还限于实验室,但以生物芯片为基础加以功能性影像学及／或活组织检查的技术将会使与临床密切相关的一些问题得到解决。 Progress in molecular biology and cell biology is deepening people’s understanding of breast cancer and brings great hope for the future radiotherapy of breast cancer. Both of these studies will also make the molecular basis of radiotherapy classification and the response of tumor and normal tissue after radiotherapy clear. In clinical applications, the molecular characteristics of tumors provided by molecular biology and cell biology will help patients to choose the treatment options. Although some studies are limited to laboratories, the use of biochip-based techniques for functional imaging and / or biopsy will solve some of the most clinically relevant problems.
