放疗在宫颈癌治疗中具有重要地位,但放疗抵抗导致局部未控仍常见,因此预测放射敏感性对制定个体化治疗策略是非常有益的。影响放射敏感性的因素有很多,p53状态是重要因素之一,p53基因上下游信号分子的调控亦能影响宫颈癌放射敏感性。本文分析了p53基因在不同宫颈癌中的差异,并探讨p53调控放射敏感性的可能方式。
Radiotherapy is a major local treatment for cervical cancer.However, local uncontrollability due to radioresistance is still common.Therefore, the prediction of radiosensitivity is quite beneficial to develop an optimal treatment strategy for individual patients.Multiple factors could influence the radiosensitivity of cells, and p53 status is one of them.The upstream or downstream molecules of p53 could also be regulated to affect the radiosensitivity of cervical cancer.The aim of the review is to analyze the difference in p53 status between different types of cervical cancer and to discuss how p53 regulates the response to radiotherapy.
