Abstract

Introduction: The extent of spread through air spaces (STAS) is less investigated among patients with lung adenocarcinoma who underwent sublobar resection. Therefore, we aimed to evaluate the extent of STAS semi-quantitatively, to assess its prognostic impact on overall survival (OS) and recurrence-free survival (RFS), and to investigate the reproducibility of this assessment.

Methods: The number of tumour cell clusters and single tumour cells within air spaces was recorded in three different most prominent areas (200x field of view). The extent of STAS was categorized into three groups, and the presence of free tumour cluster (FTC) was recorded.

Results: Sixty-one patients were included. Recurrence was more frequent with higher grade (p = 0.003), presence of lymphovascular invasion (p = 0.027), and presence of STAS of any extent (p = 0.007). In multivariate analysis, presence of FTC (HR: 5.89; 95% CI: 1.63-21.26; p = 0.005) and more pronounced STAS (HR: 7.46; 95% CI: 1.60-34.6; p = 0.01) had adverse impact on OS and RFS, respectively. Concerning reproducibility, excellent agreement was found among STAS parameters (ICC range: 0.92-0.94).

Discussion: More extensive STAS is an unfavourable prognostic factor in adenocarcinomas treated with sublobar resection. As the evaluation of extent of STAS is reproducible, further investigation is required to gather more evidence.

肺腺癌肺间隙扩散越广泛,预后越差:肺腺癌肺间隙扩散的半定量评价
在肺腺癌行肺叶下切除术的患者中,通过空气间隙(STAS)扩散的程度研究较少。因此,我们旨在半定量地评估STAS的程度,评估其对总生存期(OS)和无复发生存期(RFS)的预后影响,并研究该评估的可重复性。方法:在三个不同的最突出区域(200x视场)记录空气空间内肿瘤细胞簇和单个肿瘤细胞的数量。将STAS的范围分为三组,并记录游离肿瘤簇(FTC)的存在。结果:纳入61例患者。复发频率高,分级高(p = 0.003),存在淋巴血管侵犯(p = 0.027),存在任何程度的STAS (p = 0.007)。在多变量分析中,FTC的存在(HR: 5.89;95% ci: 1.63-21.26;p = 0.005)和更明显的STAS (HR: 7.46;95% ci: 1.60-34.6;p = 0.01)分别对OS和RFS产生不利影响。在重现性方面,STAS参数间的一致性较好(ICC范围:0.92 ~ 0.94)。讨论:更广泛的STAS是采用叶下切除术治疗腺癌的不利预后因素。由于对STAS程度的评价具有可重复性,需要进一步调查以收集更多证据。
