Br J Cancer:无肿瘤距离(TFD):早期宫颈癌患者的新预后指标

2020-12-29 xiaozeng MedSci原创

早期宫颈癌的预后标志物可用于调整患者的手术类型,包括淋巴结分期、子宫旁切除术的类型以及最重要的辅助治疗的应用。既往的大多数研究的主要局限性在于,研究期间两种临床治疗方法特别是评估单个标记的方法的标准化

早期宫颈癌的预后标志物可用于调整患者的手术类型,包括淋巴结分期、子宫旁切除术的类型以及最重要的辅助治疗的应用。既往的大多数研究的主要局限性在于,研究期间两种临床治疗方法特别是评估单个标记的方法的标准化不足。

为了避免这些局限性,研究人员通过在单一机构数据库中对一大批患者进行评估,评估了大多数传统方法和少数很少进行评估的临床和病理学变量。


预测宫颈癌复发风险(RR)的模型可用于在根治性手术后调整辅助治疗策略。该研究旨在比较可用的预后因素,并开发一种易于标准化的并在常规临床实践中能够使用的预后模型。

研究流程图

该研究通过收集在单个转诊中心(01/2007-12/2016)接受过初次手术治疗的早期子宫颈癌者,通过标准化的术前影像学检查和病理检查方法进行评估,所有患者均符合条件。研究人员在379例患者中共评估了15种预后指标,其中的320例患者表现为淋巴结(LN)阴性。


结果显示,整个队列的最佳预测模型需要结合无肿瘤距离(TFD)≤3.5 mm以及LN阳性两个亚组,而将两个亚组分开时,患者的RR显著不同,分别为36%和6.5%。在LN阴性患者中,TFD≤3.5mm的患者和腺鳞癌的组合分析可将9例RR为33%的患者与其余的RR为6%的患者分离。

无肿瘤距离(TFD)的评估

总而言之,该研究结果显示,新确定的预后指标TFD在RR评估中超过了所有传统的肿瘤相关标志物。结合TFD、LN状况或肿瘤类型的预测模型或可用于之后的日常实践中,可帮助识别具有更高RR风险的患者。
