This article reviews the experience available to date on microcirculation assessment in cancer of the cervix including correlation studies of magnetic resonance (MR) microcirculatory parameters with histo-morphometric predictors and direct correlation with patient outcome. The data suggest that MR microcirculation parameters do not always correlate with histo-morphometric parameters, while there is evidence that MR parameters predict patients' treatment outcome. These observations raise the issue that perhaps the histo-morphometric parameters, accepted gold standards for tumor angiogenesis and prognostic factors, reflect anatomical information at a "static" single time point and may not always provide sufficient information on the "dynamic" microcirculation function of the tumor. MR microcirculation assessment reflects both anatomical and functional information and may provide this additional information on the "dynamic" angiogenic and metabolic status of a tumor. Therefore, assessment of tumor microcirculation may augment the individual risk profile in cervical cancer patients and has the potential to impact on therapy selection and treatment outcome.
本文回顾了目前在宫颈癌微循环评估方面的经验,包括磁共振(MR)微循环参数与组织形态学预测指标的相关性研究以及与患者预后的直接相关性。数据表明,MR微循环参数并不总是与组织形态学参数相关,而有证据显示MR参数可预测患者的治疗结果。这些观察结果引发了一个问题,即作为肿瘤血管生成和预后因素公认金标准的组织形态学参数,可能仅反映了“静态”单一时间点的解剖信息,未必总能提供关于肿瘤“动态”微循环功能的充分信息。MR微循环评估既能反映解剖信息,又能反映功能信息,可能会提供有关肿瘤“动态”血管生成和代谢状态的额外信息。因此,肿瘤微循环评估可能会完善宫颈癌患者的个体风险概况,并有可能影响治疗方案的选择和治疗结果。
