Chest:NSCLC伴有脏层胸膜浸润(VPI)的改良病理T分期:来自中肿1055例≤3cm NSCLC病例分析

2021-12-24 yd2105 MedSci原创

研究表明,对于≤3cm NSCLC患者,PL1应该仍被定义为T1期而非T2期。同时在淋巴结阴性,≤3cm以及PL1的NSCLC患者中应避免术后辅助化疗。

脏层胸膜浸润(VPI)被认为是非小细胞肺癌NSCLC)患者的不良预后因素。VPI的阳性将T1期增加至T2,从而IA期变成IB。对于IB期伴有VPI阳性患者,可建议术后辅助化疗。但是,VPI对于NSCLC患者预后的影响仍有争议。2008年,国际肺癌研究协会(IASLC)提出VPI病理标准,建议使用弹力纤维染色进行VPI诊断。根据标准胸膜侵犯分四个层次:PL0浅表侵入脏层胸膜弹力层;PL1,越过弹力层,但未侵入间皮层;PL2,侵犯脏层胸膜;PL3,侵犯壁层胸膜。对于肿瘤大小≤3cm患者,PL1和PL2被认为是T2期。但是PL1是否跟PL2一样对患者OS有影响?现有的研究结果仍存在矛盾。可能跟研究使用的方法诊断VPI有关,某些使用HE染色,某些使用弹力纤维染色。因此,来自中山大学肿瘤防治中心的杨浩贤教授团队开展了相关研究,目的是评估VPI对肿瘤大小≤3cm的NSCLC患者生存的影响。VPI诊断同时使用HE染色和弹力纤维染色。研究还提出了一种基于VPI的改良T分期,使分期更加准确。相关研究结果发表在Chest杂志上。

本研究共纳入1055例肿瘤大小≤3cm的原发NSCLC患者。组织学分型以腺癌为主(n=908, 86.1%)。以病理性I期居多(n=685, 64.9%)。PL1和PL2组的肿瘤比PL0组的更大(PL0 vs PL1: P<0.01; PL0 vs PL2: P=.042),PL1和PL2组患者比PL0组有更高的病理N分期(PL0 vs PL1: P<0. 01;PL0 vs PL2: P<0.01)。PL1组和PL2组的肿瘤大小类似(P=0.592)。此外,PL1组和PL2组的病理N分期、病理分期和辅助治疗类似。

824例患者诊断VPI为PL0, 133例患者诊断为PL1, 98例患者诊断为PL2。

总体人群中位随访时间为49.4个月,范围为1.4 ~ 191.1个月。1055例患者中,随访期间有265例(25.1%)患者复发。复发类型仅局部复发49例(18.5%),局部复发合并远处转移57例(21.5%),仅远处转移159例(60.0%)。PL0、PL1和PL2患者的5年DFS率分别为62.6%、60.2%和28.8% (P<0.01),而相应的5年OS率分别为78.6%、74.4%和50.0% (P<0. 01)。

当PL1和PL2患者合并在一起时,这些患者的DFS和OS比PL0患者差(P<0.01)。然而,PL0, PL1,和PL2三组患者相比,无论是DFS (P=0.198)还是OS(P=0.150),PL0和PL1患者类似。但是PL2患者的预后较PL0和PL1患者的差(P<0.01)。

             三组DFS和OS差异

当只考虑淋巴结阴性患者时,数据再次表明PL0和PL1患者的长期生存类似(DFS: P=0.468;OS: P=0.388),但PL2患者的DFS和OS比PL0和PL1患者差得多(P<0.01)。然而,当仅考虑淋巴结阳性患者时,三组患者的长期生存类似。

          淋巴结阴性和阳性分层三组的DFS和OS差异

多因素分析发现,PL2(hazard ratio [HR], 1.692; 95% CI, 1.251-2.289; P <0.01),淋巴结阳性(N1: HR, 1.976; 95% CI, 1.453-2.688; P <0.01; N2: HR, 2.412; 95% CI, 1.855-3.136; P <0.01), 以及目前吸烟中(HR, 1.616; 95% CI, 1.286-2.031; P <0.01)是DFS不良独立预后因素。而PL2 (HR, 2.169; 95% CI, 1.494-3.149; P <0.01), 淋巴结阳性(N1: HR, 2.765;95% CI, 1.870-4.089; P <0.01; N2: HR, 3.118; 95% CI,2.203-4.413; P <0.01), 以及目前吸烟中(HR, 1.730; 95% CI, 1.281-2.335; P <0.01)是OS不良独立预后因素。

              DFS和OS多因素分析

进一步分析,仅纳入N0患者时,研究显示PL2和较差细胞分化是DFS和OS不良独立预后因素。

综上,研究表明,对于≤3cm NSCLC患者,PL1应该仍被定义为T1期而非T2期。同时在淋巴结阴性,≤3cm以及PL1的NSCLC患者中应避免术后辅助化疗。
