目的 探讨128层螺旋CT灌注成像对宫颈癌血管生成及新辅助化疗疗效的分析价值.方法 收集医院治疗的宫颈癌患者86例作为研究对象,其中直接手术治疗的45例,进行新辅助化疗的41例.对比不同病理类型患者CT灌注成像参数、与血管生成相关性、新辅助化疗前后以及不同临床疗效患者的CT灌注成像参数.结果 鳞癌的血流量(BF)、血容量(BV)、表面通透性(PS)均显著高于腺癌,造影剂平均通过时间(MTT)显著低于腺癌;FIGO分期高、分化程度低、淋巴结转移阳性患者的BF、BV、PS均高于FIGO分期低、分化程度高、淋巴结转移阴性的患者,而MTT显著降低(P<0.05).CT灌注成像中,BF、BV、PS与微血管密度(MVD)呈正相关,MTF与MVD呈负相关(P<0.05).新辅助化疗后,患者的BF、BV、PS均明显降低,而MTT明显升高;临床有效组的BF、BV、PS高于无效组,而MTT均低于无效组(P<0.05).结论 128层螺旋CT灌注成像可从血流动力学方面提供肿瘤信息,对于宫颈癌血管生成及新辅助化疗疗效具有较高的分析价值.
Objective To explore the value of 128-layer spiral CT perfusion imaging in angiogenesis and neo-adjuvant chemotherapy of cervical cancer.Methods A total of 86 patients with cervical cancer admitted to our hospital were selected as study subjects,among which 45 ones received direct surgical treatment and 41 ones received neo-adjuvant chemotherapy.The CT perfusion imaging parameters and the correlation with angiogenesis in patients with different pathological types and the CT perfusion imaging parameters in patients before and after neo-adjuvant chemotherapy and with different clinical effects were compared.Results The blood flow (BF),blood volume (BV) and permeability surface of the patients with squamous carcinoma were significantly higher than those of the patients with adenocarcinoma,and the mean transit time (MTT) of contrast medium was much shorter than that of the patients with adenocarcinoma;the BF,BV and PS of the patients with high FIGO staging,low differentiated degree and positive lymph node metastasis were higher than those of the patients with low FIGO staging,high differentiated degree and negative lymph node metastasis,with the MTT significantly shorter (P < 0.05).In CT perfusion imaging,BF,BV and PS were positively correlated with microvessel density (MVD),while MTT was negatively correlated with MVD (P < 0.05).After neo-adjuvant chemotherapy,the BF,BV and PS of the patients decreased significantly,but MTT increased significantly;the BF,BV and PS in the clinically effective group were higher than those in the ineffective group,but MTT was shorter than that in the ineffective group (P < 0.05).Conclusion 128-layer spiral CT perfusion imaging can provide tumor information from hemodynamics and has significant value in the analysis of cervical cancer angiogenesis and effects of neo-adjuvant chemotherapy.
