中文摘要:
      目的 评估功能MR成像联合临床预后因素(CPF)预测宫颈鳞癌患者同步放化疗(CCRT)的疗效。方法 59例宫颈鳞癌患者CCRT治疗前在3.0T MR上进行常规MRI,DWI和DCE-MRI扫描。根据CCRT治疗后三个月的随访MRI并结合临床检查,将患者分为两组:有肿瘤残余和无肿瘤残余组。比较两组之间的功能MRI参数和CPF(肿块大小,FIGO分期,淋巴结转移)的差异。结果 肿瘤残余组在治疗前肿瘤低强化区域的最大上升斜率(MSIL)和信号强化率(SERL)显著低于无肿瘤残余组,而ADC值和FIGO分期,淋巴结转移高于无肿瘤残余组(P均<0.05)。将MSIL和ADC值结合预测CCRT治疗后肿瘤残余发生的诊断效能高于单个MRI参数;MRI多参数与CPF结合进一步提高了预测效能。结论 治疗前MSIL和ADC值是CCRT治疗后肿瘤残余发生的独立预后因素。MRI多参数与CPF结合预测CCRT疗效的诊断效能最高。
英文摘要:
      Objective To predict response to concurrent chemoradiotherapy (CCRT) through a combination of functional MRI with clinical prognostic factors(CPF)in patients with cervical squamous cell carcinoma (SCC). Methods Fifty-nine patients with SCC underwent conventional MRI, DWI and DCE-MRI before CCRT. The patients were divided into non- and residual tumour groups according to post-treatment 3 month MRI combined with clinical examination. Pre-treatment functional MRI parameters and CPF between the two groups were compared. Results There were a significantly lower pre-treatment MSIL and SERL , higher ADC value, FIGO staging and lymph node metastasis in post-treatment residual tumors group than in non-residual tumors group(P all <0.05). A combination of MSIL and ADC with CPF improved a diagnostic performance compared with individual MRI parameter. Conclusions Pre-treatment MSIL and ADC were independent prognostic factors for post-treatment residual tumor. The combination of multi-parametric MRI with CPF exhibited the highest predictive performance.
