宫颈癌近距离放疗的研究进展.

Cervical cancer is the most common malignant tumor of female reproductive tract in China, which seriously threatens women′s health. Brachytherapy is an essential component of the treatment of locally advanced cervical cancers. It enables the dose to the tumor to be boosted whilst allowing relative sparing of the normal tissues. In recent years, three - dimensional brachytherapy, interstitial implantation brachytherapy and radioactive seed implantation brachytherapy have developed rapidly． These technologies have improved the treatment effect of cervical cancer and reduced complications. The three factors are interrelated. For eccentric tumor, intracavitary brachytherapy has incomplete target coverage and poor dose distribution conformation, while interstitial implantation brachytherapy can make up for the deficiency of intracavitary brachytherapy. Radioactive seed implantation brachytherapy has the characteristics of low trauma and high safety, providing more possibilities for patients with recurrent cervical cancer. Therefore, individualized treatment plan should be formulated according to the characteristics of the patient′s condition in clinical practice. [ABSTRACT FROM AUTHOR]
