Background This study analyzed the impact of visceral pleural invasion (VPI) on the disease-free survival (DFS) of patients with partly solid pulmonary adenocarcinoma sized 30 mm or smaller. Method This is a retrospective study of 147 patients with surgically resected pathologic N0 pulmonary adenocarcinoma that had a partly solid appearance on preoperative computed tomography. All patients presented with tumors of size 30 mm or smaller. The DFS rate was estimated using Kaplan–Meier method. A multivariate analysis for prognostic factors was performed using the Cox proportional hazards regression model. Results VPI was found in 36 patients. The 5-year DFS in 111 patients without VPI (97.6%) was significantly higher than that in 36 patients with VPI (63%) (p < 0.0001). Univariate analysis revealed three significant poor prognostic predictors: the presence of VPI, the presence of lymphovascular invasion, and the size of the solid component on computed tomography (>20, ≤30 mm). According to the multivariate analysis, VPI was found to be a significant poor prognostic predictor (hazard ratio for DFS = 7.31, 95% confidence interval = 1.444–37.014, p = 0.016). Conclusion VPI is a significant predictor of poor prognosis for small-sized (≤30 mm) partly solid lung adenocarcinoma. Therefore, upstaging of the T factor from T1 to T2 on the basis of VPI as described by the TNM staging system is mandatory regardless of ground-glass opacity in small lung adenocarcinoma.

Abstract Background: To investigate whether thin-section computed tomography (TSCT) features may efficiently guide the invasiveness basedclassification of lung adenocarcinoma. Methods: Totally, 316 lung adenocarcinoma patients (from 2011-2015) were divided into three groups: 56 adenocarcinoma in situ (AIS), 98 minimally invasive adenocarcinoma (MIA), and 162 invasive adenocarcinoma (IAC) according their pathological results. Their TSCT features, including nodule pattern, shape, pleural invasion, solid proportion, border, margin, vascular convergence, air bronchograms, vacuole sign, pleural indentation, diameter, solid diameter, and CT values of ground-glass nodules (GGN) were analyzed. Pearson’s chi-square test, Fisher’s exact test and One-way ANOVA were adopted tocomparebetweengroups. Receiver operating characteristic (ROC) analysis wereperformedto assess its value for prediction and diagnosis. Results: Patients with IAC were significantly elder than those in AIS or MIA group,and more MIA patients had a smoking history than AIS and IAC. No recurrence happened in the AIS and MIA groups, while 4.3% recurrences were confirmed in the IAC group. As for TSCT variables, we found AIS group showed dominantly higher 91.07%PGGN pattern and 87.50% round/oval nodules than that in MIA and IAC group. In contrast, MIA group showed more cases with undefined border and vascular convergence than AIS and IAC group. Importantly, IAC group uniquely showed higher frequency of pleural invasion compared with MIA and AIS group. The majority of patients (82.1%) in IAC group showed ≥ 50% solid proportion. We found diameter and solid diameter of the lesions were notably larger in the IAC group compared with AIS and MIA groupin quantitative aspect. In addition, for MGGNs, the CT values of ground-glass opacity (GGO) and ground-glass opacity solid portion (GGO-solid) were both higher in the IAC group than AIS and MIA. Finally, we also observed that smooth margin took a dominant proportion in the AIS group while most cases in the IAC group had a lobulate margin. Patients in MIA and IAC group shared higher level of air bronchograms and vacuole signs than AIS group. Conclusions: The unique features in different groups identified by TSCT had diagnosis value for lung adenocarcinoma.

Abstract Objectives We prospectively investigate the accuracy of frozen sections for diagnosing visceral pleural invasion (VPI) by autofluorescence and evaluated its usefulness in sublobar resection. Methods We included patients with lung adenocarcinoma 2 cm or less to evaluate the diagnostic performance of autofluorescence for VPI in frozen sections via a fluorescence microscope. Furthermore, the impact of VPI on patients treated with sublobar resection was assessed in another cohort. Results A total of 112 patients were enrolled. The accuracy, sensitivity, and specificity of autofluorescence for VPI diagnosis was 95.5%, 86.8%, and 100%, respectively. Sublobar resection was an independent risk factor for recurrence in patients with lung adenocarcinomas 2 cm or less with VPI positivity (hazard ratio, 3.30; P = .023), whereas it was not in those with VPI negativity. Conclusions Using autofluorescence in frozen sections appears to be an accurate method for diagnosing VPI, which is helpful for surgical decision making.

e21028 Background: The ability to enrich and interrogate circulating tumor cells (CTCs) from blood may allow for the analysis of metastatic dissemination and potential use of CTCs as surrogates for monitoring drug efficacy. We developed ApoStream, a dieletrophoresis field-flow fractionation based platform, for antibody-independent CTC isolation. We demonstrated that ApoStream successfully isolates non-small cell lung adenocarcinoma (NSCLC) CTCs that express Folate Receptor alpha (FRA), a GPI-anchored receptor, which has emerged as a cancer biomarker and potential therapeutic target in multiple cancer types. Methods: ApoStream technology was used to enrich CTCs from NSCLC patients’ blood. CTC enrichment by ApoStream was compared to that of the FDA cleared CellSearch CTC kit. A multiplexed immunofluorescent assay was developed to enable CTC enumeration (Cytokeratin+/CD45-/DAPI+ cells) and analysis of FRA expression (detection by murine antibody clone 26B3) using single cell quantitative laser scanning cytometry (LSC). Results: In a side-by-side comparison with the CellSearch CTC kit, ApoStream isolated significantly higher numbers of CTCs in 9 metastatic adenocarcinoma NSCLC patients (Apostream: mean =139, range 3-487 per 7.5 mL of blood, versus CellSearch kit: mean =2, range 0-8 per 7.5 mL of blood, n= 9, p=0.041). All patients were found to be CTC-positive by ApoStream, while only 3 of 9 (33%) patients were CTC-positive based on the CellSearch kit. LSC analysis demonstrated that 8-33% of all CTCs isolated expressed FRA and that FRA expression was confined to CTCs only. No false positive CTCs and no FRA-expressing cells were isolated by ApoStream from normal donor blood (n=15). Conclusions: All NSCLC adenocarcinoma patients analyzed had FRA-positive CTCs, suggesting that FRA may play a key role in metastasis and that screening of patients with the ApoStream CTC isolation system may identify patients who could benefit from FRA-targeted therapy.
