Ann Surg Oncol 2023; 30:7481-7491. [PMID: 37535274 DOI: 10.1245/s10434-023-14016-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Accepted: 06/27/2023] [Indexed: 08/04/2023]
Abstract
BACKGROUND This study aimed to determine the prognostic factors for the long-term outcome of stage IB non-small cell lung cancer (NSCLC). METHODS Surgically resected patients with stage IB NSCLC diagnosed (based on TNM 8th edition) between April 2008 and December 2013 were retrospectively reviewed. The prognosis and possible risk factors among the stage IB NSCLC patients were evaluated. RESULTS Of the 349 patients identified for the study, 80 (22.9%) received post-surgery adjuvant chemotherapy (ACT). The median follow-up time after surgery was 123.3 months. The 10-year overall survival (OS) rate was 69.6%, and the 10-year recurrence-free survival (RFS) rate was 62.8%. The patients in this cohort were divided into three groups (T1 with visceral pleural invasion [VPI], T2a without VPI, and T2a with VPI), and no significant differences in OS or RFS were found among the groups. Furthermore, survival analysis indicated that the absence of ground-glass opacity (GGO) components portends an adverse long-term OS and RFS. In a subgroup of patients with solid nodules, age older than 65 years (hazard ratio [HR] 1.987; 95% confidence interval [CI] 1.312-3.010; p = 0.001) and ACT (HR 0.392; 95% CI 0.225-0.684; p < 0.001) were independent prognostic factors for OS, whereas lymphovascular invasion (HR 1.792; 95% CI 0.995-3.227; p = 0.052) should be considered as an independent unfavorable prognostic factor for RFS. CONCLUSIONS As an upstaging factor, VPI did not further stratify prognosis for the stage IB patients in our cohort. The presence of GGO components had a notable impact on a favorable prognosis in stage IB NSCLCs.

Abstract
Nodal metastasis status is an important parameter affecting the prognosis in lung cancer. Although surgical treatment is possible in most cases of N1 positive non-small cell lung cancer, this group of patients is clinically, radiologically and histologically heterogeneous. The aim of our study is to investigate the prognostic factors affecting survival in patients with pT1-2 N1 who underwent lung resection. From January 2010 to December 2019, patients who underwent lobectomy, bilobectomy or pneumonectomy for pT1-T2 N1 NSCLC in our center were included in the study. The preoperative, intraoperative and postoperative data of the patients were recorded by accessing the patient files and hospital records. The mean follow-up time was 39.8 months. The mean overall survival was 73.8 ± 3.6, and the mean disease-free survival was 67.5 ± 3.8. In multivariate analysis, age, N1 nodal metastasis pattern (occult vs obvious) and histology were found as independent variables affecting survival. In our study, age, histology, and clinical N1 status were found to be independent variables effective on overall survival.

Abstract
Background: Pleural metastasis in lung cancer found at diagnosis has a poor prognosis, with 5–11 months’ survival. We hypothesized that prognosis might be different for patients who have had curative-intent surgery and subsequent pleural recurrence and that survival might differ based on the location of the first metastasis (distant versus pleural). This may clarify if pleural recurrence is a local event or due to systemic disease. Methods: A database of 5089 patients who underwent curative-intent surgery for lung cancer was queried, and 85 patients were found who had biopsy-proven pleural metastasis during surveillance. We examined survival based on pattern of metastasis (pleural first versus distant first/simultaneously). Results: Median survival was 34 months (range: 1–171) from the time of surgery and 13 months (range: 0–153) from the time of recurrence. The shortest median survival after recurrence was in patients with adenocarcinoma and pleural metastasis as the first site (6 months). For patients with pleural metastasis as the first site, those with adenocarcinoma had a significantly shorter post-recurrence survival when compared with squamous cell carcinoma (6 vs. 12 months; HR = 0.34) and a significantly shorter survival from the time of surgery when compared with distant metastases first/simultaneously (25 vs. 52 months; HR = 0.49). Conclusions: Patients who undergo curative-intent surgery for lung adenocarcinoma that have pleural recurrence as the first site have poor survival. This may indicate that pleural recurrence after lung surgery is not likely due to a localized event but rather indicates systemic disease; however, this would require further study.

Abstract
Objectives To assess the association between common-used serum tumor markers and recurrence of lung adenocarcinoma and squamous cell carcinoma separately and determine the prognostic value of serum tumor markers in lung adenocarcinoma featured as ground glass opacities. Methods A total of 2,654 non-small cell lung cancer patients undergoing surgical resection between January 2008 and September 2014 were analyzed. The serum levels of carcinoma embryonic antigen (CEA), cytokeratin 19 fragment (CYFRA21-1), neuron-specific enolase (NSE), carbohydrate antigen 125 (CA125), carbohydrate antigen 153 (CA153) and carbohydrate antigen 199 (CA199) were tested preoperatively. Survival analyses were performed with COX proportional hazard regression. Results Among patients with lung adenocarcinoma, elevated preoperative serum CEA(HR=1.246, 95%CI:1.043-1.488, P=0.015), CYFRA21-1(HR=1.209, 95%CI:1.015-1.441, P=0.034) and CA125(HR=1.361, 95%CI:1.053-1.757, P=0.018) were significantly associated with poorer recurrence free survival (RFS). Elevated preoperative serum CA199 predicted worse RFS in patients diagnosed with lung squamous cell carcinoma (HR=1.833, 95%CI: 1.216-2.762, P=0.004). Preoperative serum CYFRA21-1(HR=1.256, 95%CI:1.044-1.512, P=0.016) and CA125(HR=1.373, 95%CI: 1.050-1.795, P=0.020) were independent prognostic factors for patients with adenocarcinoma presenting as solid nodules while serum CEA (HR=2.160,95%CI:1.311-3.558, P=0.003) and CA125(HR=2.475,95%CI:1.163-5.266, P=0.019) were independent prognostic factors for patients with adenocarcinoma featured as ground glass opacities. Conclusions The prognostic significances of preoperative serum tumor markers in non-small cell lung cancer were associated with radiological features and histological types.

Abstract
OBJECTIVE Accurate diagnosis and prognosis are essential in lung cancer treatment selection and planning. With the rapid advance of medical imaging technology, whole slide imaging (WSI) in pathology is becoming a routine clinical procedure. An interplay of needs and challenges exists for computer-aided diagnosis based on accurate and efficient analysis of pathology images. Recently, artificial intelligence, especially deep learning, has shown great potential in pathology image analysis tasks such as tumor region identification, prognosis prediction, tumor microenvironment characterization, and metastasis detection. MATERIALS AND METHODS In this review, we aim to provide an overview of current and potential applications for AI methods in pathology image analysis, with an emphasis on lung cancer. RESULTS We outlined the current challenges and opportunities in lung cancer pathology image analysis, discussed the recent deep learning developments that could potentially impact digital pathology in lung cancer, and summarized the existing applications of deep learning algorithms in lung cancer diagnosis and prognosis. DISCUSSION AND CONCLUSION With the advance of technology, digital pathology could have great potential impacts in lung cancer patient care. We point out some promising future directions for lung cancer pathology image analysis, including multi-task learning, transfer learning, and model interpretation.

Abstract
Clinical staging of non-small cell lung cancer (NSCLC) is used for planning therapeutic strategies. In particular, pleural invasion is regarded as an indicator for upstaging to T2 or T3 in the current 8th TNM staging system; patients with pleural invasion should be indicated for lobectomy rather than sublobar resection. Therefore, accurate preoperative prediction of pleural invasion is important for surgical planning. In recent years, different radiological investigations for patients with NSCLC have been widely used, and methods for more precise detection have been developed in the current medical imaging studies. Therefore, several radiological investigation tools have been used for the prediction of pleural invasion. In this article, to identify the imaging modalities for accurate prediction of pleural invasion, we reviewed the different methods used for this purpose and discussed their advantages and limitations.

Abstract
In the US, lung carcinoma accounted for over 150,000 deaths in 2018 and the advances in increasing survival rates are still limited. In this study, we investigated the cohorts with lung adenocarcinoma (LUAD) or lung squamous cell carcinoma (LUSC) from The Cancer Genome Atlas to figure out the risk factors and genomic alterations that affected their prognosis. The histoclinical factors that differed between LUAD and LUSC were identified and the risk factors affecting the overall survival were figured out for both LUAD and LUSC. Next, the patterns of nucleotides substitutions and the mutational signatures were extracted to illustrate whether different mutational processes performed for them. Finally, the genes that had different frequencies of mutation were identified. LUAD and LUSC presented differences in histoclinical factors including age at the time of diagnosis, sex, smoking history, pathological T classification, and overall survival. This was caused by the distinct genomic alterations including the transition-to-transversion ratios, mutational signatures, and the frequently mutated genes. We proposed that the mutational signature associated with aging could be used to predict the prognosis of patients with LUAD. On the other hand, the AID/APOBEC family was associated with the prognosis of LUSC. Finally, SNTG1 and LRRK2 might be important in LUAD and LUSC, respectively.

Abstract
Based on 4D-CT, we aimed to characterize the pattern of morphological changes in lung tumors during respiration, and investigated its potential in non-invasively differentiating lung adenocarcinoma (AC) and squamous cell carcinoma (SCC). We applied a 3D surface analysis on 22 tumors (13 AC, 9 SCC) to investigate the tumor regional morphological fluctuations in response to respiration phases. Tumor surface vertices among ten respiratory phases were matched using surface-based registration, and the shape descriptors (ρ and detJ) were calculated and tracked across respiration stages in a regionally aligned scenario. Pair-wise group comparisons were performed between lung AC and SCC subtypes, in terms of ratios of maximal shape changes as well as correlation coefficients between tumor shape and respiratory stage indicators from the lung. AC type tumors had averaged larger surface measurements at exhale than at inhale, and these surface measurements were negatively correlated with lung volumes across respiratory stages. In contrast, SCC type tumors had averaged smaller surface measurements at exhale than at inhale, and the correlations with lung volumes were positive. The group differences in maximal shape changes as well as correlations were both statistically significant (p < 0.05). We developed a non-invasive lung tumor sub-type detection pipeline based on respiration-induced tumor surface deformation. Significant differences in deformation patterns were detected between lung AC and SCC. The derived surface measurements may potentially serve as a new non-invasive imaging biomarker of lung cancer subtypes.

Abstract
BACKGROUND There is currently no definite clinical implication for the subtypes of lung squamous cell carcinoma according to the 2015 WHO classification. This study aimed to investigate postoperative recurrence of the two major subtypes of lung squamous cell carcinoma: keratinizing squamous cell carcinoma (KSCC) and nonkeratinizing squamous cell carcinoma (NKSCC). METHODS We identified the patients with KSCC and NKSCC who had undergone complete resection in Shanghai Chest Hospital between April 2015 and June 2016. Disease-free survival (DFS) was compared using Kaplan-Meier statistical analysis. Variables selected by univariate analysis were evaluated in multivariate analysis using the Cox proportional hazard model. RESULTS A total of 334 patients included 231 (69.2%) cases with KSCC and 103 (30.8%) cases with NKSCC. There were more smokers in keratinizing than nonkeratinizing subtype (84.8% versus 72.8%, p = 0.009). The percentage of stage Ⅲ was higher in NKSCC than that in KSCC (35% versus 22.9%, p = 0.012). The 2-year DFS rates of stage Ⅰ, stage Ⅱ and stage Ⅲ were 90.1%, 66.4% and 37.7% in KSCC, 83.3%, 67.7% and 52.8% in NKSCC, respectively. There were no significant differences of 2-year DFS rates between KSCC and NKSCC. Furthermore, KSCC and NKSCC had no significant differences in recurrence patterns and metastatic sites. CONCLUSION There were no significant differences of postoperative recurrence between KSCC and NKSCC.

Abstract
Background Recurrence of lung cancer after surgical resection is a major obstacle in the cure and long-term survival of patients and has become the most common cause of death. However, prognostic factors and efficacy of therapy after recurrence remain controversial. We evaluated the prognostic factors of post recurrence survival (PRS) in patients of resected stage I non-small cell lung cancer (NSCLC). Methods Of the 551 patients who underwent surgery for stage I NSCLC between 2005 and 2013, we reviewed 89 (16.2%) patients who had recurrence. We examined PRS using the Kaplan-Meier method and multivariate Cox regression analyses. Results The median follow-up period after recurrence was 21.0 months. The median recurrence free interval (RFI) was 16.8 months. The 1-year PRS and 3-year PRS were 65.6% and 44.7%, respectively. Multivariate analysis revealed that size of primary lesion > 25 mm (P = 0.048), RFI ≤ 17 months (P = 0.048) and no treatment for recurrence (P < 0.001) were independent poor-prognosis factors of PRS. We further examined PRS in 66 patients who underwent any post recurrence therapy. For the patients who underwent treatment after recurrence, bone metastasis (P = 0.025) and treatment without epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) (P = 0.049) were independent poor prognostic factors. Conclusion PRS may be associated with characteristics of a recurrent lesion, including the biology of the recurrent tumor, RFI, recurrent site, the treatment for recurrence, rather than characteristics of primary lesion. Although further validation is needed, this information is important for the design of clinical trials for post-recurrence therapy.

Abstract
To study the behavior and possible correlations of neuron-specific enolase (NSE) with other clinicobiological parameters, we measured the cytosolic levels of this marker by means of an immunoradiometric assay (IRMA) in 95 squamous cell lung carcinoma samples. We also analyzed the levels of pS2, tissue-type plasminogen activator (t-PA), hyaluronic acid (HA), free beta subunit of human chorionic gonadotropin (β-HCG), CYFRA 21.1 and CA 125 in cytosol. On the cell surface we analyzed the concentrations of epidermal growth factor receptor (EGFR), HA, erbB-2 oncoprotein, CD44s, CD44v5 and CD44v6. Other parameters considered were clinical stage, lymph node involvement, histological grade (HG), ploidy and the cellular S-phase fraction measured by flow cytometry on nuclei obtained from fresh tissues. In the 95 squamous cell carcinomas the cytosolic levels of NSE varied from 4.5 to 2235 ng/mg protein (median: 267) and were significantly higher (p<0.001) than those observed in 38 samples of normal pulmonary tissue obtained from the same patients (range: 56–657; median: 141.5). When classifying tumors according to the different parameters analyzed, we observed that the levels of NSE were higher in aneuploid than in diploid cases (p=0.046) and in those that were HG3 than in those that were HG2 (p<0.001). Tumors with high NSE levels (>422 ng/mg protein; 75th percentile) were more likely to have high S-phase values (p=0.012) and were more frequently aneuploid (p=0.038) and HG3 (p<0.001) than those with low levels of NSE (<180 ng/mg protein; 25th percentile). These results lead us to the following conclusions: 1) the cytosolic concentrations of NSE are significantly higher in squamous cell carcinomas than in healthy pulmonary tissue, and 2) the cytosolic concentrations of NSE are not correlated with clinical stage or nodal involvement. However, in our study higher levels of the enzyme were statistically correlated with aneuploidy, histological grade 3 and S-phase. This may explain its association with poorer outcome and progression, but also the more favorable response of tumors with elevated NSE to chemotherapy, as suggested by other groups.

Abstract
AIMS This study aimed to determine the relationship between clinicopathologic features and lung squamous cell carcinoma (LSCC) subtypes according to the 2015 WHO classification. METHODS We identified 824 operable LSCC patients undergoing a complete surgical resection at Shanghai Chest Hospital between April 2015 and January 2017. Immunohistochemistry was used to investigate the clinicopathologic features. RESULTS Among them, the percentages of LSCC subtypes were 66.1% (545/824), 28.6% (236/824), and 5.2% (43/824) for keratinizing squamous cell carcinoma (KSCC), nonkeratinizing squamous cell carcinoma (NKSCC), and basaloid squamous cell carcinoma (BSCC), respectively. There were more males, more smokers, and more pneumonectomy surgeries in KSCC patients (p = 0.008, p = 0.000, p = 0.043). There were more N2 lymph node involvement and pathological stage III in NKSCC patients (p = 0.01, p = 0.03). BSCC did not demonstrate specificity to anything, but expressed adenocarcinoma markers more frequently. No significant difference existed between pathological subtypes and other clinicopathologic features, such as age, location type, visceral pleural involvement and lymphovascular invasion. The frequencies of EGFR sensitive mutations and ALK rearrangements were not significantly different among three subtypes. CONCLUSION Significant relationships exist between some clinicopathologic features and LSCC subtypes.

Abstract
Pathological stage is the most important prognostic factor in patients with lung cancer, and is defined according to the tumor node metastasis classification system. The present study aimed to investigate the clinicopathological significance of lymphatic invasion in 103 patients who underwent surgical resection of lung squamous cell carcinoma (SqCC). The patients were divided into two groups, according to the degree of lymphatic invasion: Those with no or mild lymphatic invasion (ly0-1) and those with moderate or severe lymphatic invasion (ly2-3). Ly2-3 was associated with tumor size (P=0.028), lymph node metastasis (P<0.001), venous invasion (P=0.001) and histological differentiation (P=0.047). Statistical analysis using the Kaplan-Meier method and the log-rank test indicated that overall survival was significantly reduced in patients with ly2-3 compared with those with ly0-1 (P<0.001). Multivariate analysis identified ly2-3 as an independent predictor of mortality (hazard ratio, 2.580; 95% confidence interval, 1.376–4.839). In conclusion, moderate or severe lymphatic invasion (ly2-3) indicated a high malignant potential and may be considered an independent predictor of poor prognosis in patients with SqCC of the lung.

Abstract
Purpose: We aimed to establish an inflammatory prognostic index (IPI) in early and advanced non-small cell lung
cancer (NSCLC) patients based on hematologic and biochemical parameters and to analyze its predictive value for
NSCLC survival. Materials and Methods: A retrospective review of 685 patients with early and advanced NSCLC
diagnosed between 2009 and 2014 was conducted with collection of clinical, and laboratory data. The IPI was calculated
as C-reactive protein × NLR (neutrophil/ lymphocyte ratio)/serum albumin. Univariate and multivariate analyses were
performed to assess the prognostic value of relevant factors. Results: The optimal cut-off value of IPI for overall
survival (OS) stratification was determined to be 15. Totals of 334 (48.8%) and 351 (51.2%) patients were assigned to
high and low IPI groups, respectively. Compared with low IPI, high IPI was associated with older age, greater tumor
size, high lymph node involvement, distant metastases, advanced stage and poor performance status. Median OS was
worse in the high IPI group (low vs high, 8.0 vs 34.0 months; HR, 3.5; p<0.001). Progression free survival values of
the patients who had high vs low IPI were determined 6 months (95% CI:5.3-6.6) and 14 months (95% CI:12.1-15.8),
respectively (HR; 2.4, P<0.001). On multivariate analysis, stage, performance status, lactate dehydrogenase and IPI
were independent prognostic factors for OS. Subgroup analysis showed IPI was generally a significant prognostic
factor in all clinical variables. Conclusion: The described IPI may be an inexpensive, easily accessible and independent
prognostic index for NSCLC patients, useful for clinical practice.

Abstract
To clarify the prognostic factors for disease-free survival in completely resected pT2N0 non-small cell lung cancer, 81 consecutive patients who were treated between 1998 and 2001 were retrospectively reviewed. Follow-up was complete for all patients and the median follow-up time was 37.5 months. The overall 5-year survival rate was 68.6%, and the 5-year disease-free survival rate was 62.5%. Four factors (age, sex, visceral pleural invasion, and administration of tegafur and uracil) were proposed as prognostic factors for disease-free survival by univariate analysis. In multivariate analysis, visceral pleural invasion by the tumor (hazard ratio = 2.709, 95% confidence interval: 1.085 to 6.765, p = 0.033) and administration of tegafur and uracil (hazard ratio = 0.327, 95% confidence interval: 0.147 to 0.730, p = 0.006) were significant factors. Visceral pleural invasion was a prognostic factor for reduced disease-free survival in completely resected pT2N0 non-small cell lung cancer, and postoperative treatment with tegafur and uracil significantly improved disease-free survival.

Abstract
OBJECTIVE Recurrence after surgical resection is the most common cause of treatment failure in patients with non-small-cell lung cancer. The aim of the study is to investigate the prognostic factors of postrecurrence survival (PRS) in patients of resected lung adenocarcinoma. METHODS The clinicopathological characteristics of 179 patients with recurrence after complete resection of lung adenocarcinoma at Taipei Veterans General Hospital between 2004 and 2010 were retrospectively reviewed. The prognostic and predictive effects of these clinicopathological variables in PRS were analyzed. RESULTS The pattern of recurrence included local only in 25 (15.4%), distant only in 56 (34.6%), and both local and distant in 81 (50.0%) of patients. The 2-year and 5-year PRS were 65.2% and 29.8%, respectively. The most common organ sites of metastasis were the contralateral lung (39.1%), followed by the brain (33.5%) and the bone (31.3%). Multivariate analysis revealed that micropapillary/solid predominant pattern group (versus acinar/papillary; hazard ratio = 2.615; 95% confidence interval: 1.395-4.901; p = 0.003) and no treatment for recurrence (p < 0.001) were significant prognostic factors of worse PRS. For patients receiving treatment for recurrence, micropapillary/solid predominant pattern group (versus acinar/papillary; hazard ratio = 2.570; 95% confidence interval: 1.357-4.865; p = 0.004) was a significant predictive factor of worse PRS. Treatment for recurrence with surgery (p = 0.067) tended to be a significant predictive factor of better PRS. CONCLUSIONS In lung adenocarcinoma, micropapillary/solid predominant pattern group (versus acinar/papillary) was a significant poor prognostic factor for PRS.

Abstract
The aim of the present study was to explore the effects of interleukin (IL)-17 on the growth and metastasis of tumors that were subcutaneously implanted into C57BL/6 mice. Lewis lung carcinoma (LLC) cells were subcutaneously injected into C57BL/6 mice followed by intraperitoneal injection of mouse recombinant IL-17 protein (IL-17 groups) or phosphate-buffered saline (control groups). Tumor growth and metastasis were assessed by measuring the size and weight of tumors and cervical lymph nodes, respectively. Cytokine expression in tumor masses was quantified by reverse transcription-quantitative polymerase chain reaction and western blotting, respectively. CCR2-positive macrophage infiltration in tumor masses was detected by flow cytometric analysis. The proliferation and migration of LLC cells, stimulated by the IL-17 protein were detected by Cell Counting kit (CCK)-8 and wound scratch assays in vitro. Tumors were grafted into the C57BL/6 mice. The mice that were intraperitoneally injected with IL-17 exhibited significantly larger tumors compared with the control mice. After day 7 of injection and beyond, the weight of cervical lymph nodes in IL-17 groups was higher than that in the control mice. It was also demonstrated that the number of CCR2-positive macrophages that infiltrated the tumor masses in the IL-17 groups was higher than that of the control mice. CD34 expression in vascular endothelial cells was also higher in tumors grafted in IL-17 mice than those grafted in control mice. Furthermore, the tumor tissue mRNA and protein expression levels of vascular endothelial growth factor, matrix metalloproteinase (MMP)-2, MMP-9 and tumor necrosis factor-α were greater in mice from the IL-17 group than the control mice, while levels of migration inhibitory factor and thrombospondin-1 were lower in mice from the IL-17 group than in the control. IL-17 also increased the migration of LLC cells in vitro. In conclusion, IL-17 exhibited the ability to promote tumor growth by increasing angiogenesis, metastasis and increasing CCR2+ macrophage infiltration into tumors.

Abstract
Poor clinical outcome of lung cancer (LuCa) is primarily due to lack of knowledge about specific molecules involved in its progression and metastasis. In this study, we for the first time show the clinical and biological significance of CC chemokine receptor-9 (CCR9) in non-small cell lung cancer (NSCLC). Expression of CCR9 and CCL25, the only natural ligand of CCR9, was significantly higher (p < 0.0001) in NSCLC tissues and serum respectively, compared to their respective controls. Interestingly, expression of both CCR9 and CCL25 was significantly higher in adenocarcinomas (ACs) compared to squamous cell carcinomas (SCCs) (p = 0.04, and p < 0.0001). Similar to tissues, AC and SCC cell lines were positive for CCR9 expression. Despite of marginal difference in CCR9 expression, AC cells showed higher migratory and invasive potential in response to CCL25, compared to SCC cells. This differential biological response of AC cells was primarily due to differential expression of matrix metalloproteinases and tissue inhibitor of metalloproteinases under the influence of CCL25. Our results suggest CCR9 as a potential target for developing new treatment modality for NSCLC. Additionally, differential serum CCL25 level in ACs and SCCs, two NSCLC subtypes, suggest its potential as a non-invasive diagnostic/prognostic biomarker.

Abstract
背景与目的 血清癌胚抗原(carcinoembryonic antigen, CEA)和细胞角蛋白19的可溶性片段(soluble fragment of cytokeratin-19, CYFRA21-1)系非小细胞肺癌(non-small cell lung cancer, NSCLC)患者术前检查重要的肿瘤标志物(tumor markers, TMs),但其对NSCLC患者术后的预后作用尚存争议。本研究旨在探讨血清CEA和CYFRA21-1在手术治疗后的NSCLC患者预后中的临床价值。 方法 回顾性总结175例经手术并辅以化疗的NSCLC患者的临床资料及随访情况,依据CEA、CYFRA21-1水平进行分组,用Kaplan-Meier法对各组进行生存分析。用Cox比例风险回归模型分析影响NSCLC患者术后预后的因素。 结果 术前CEA、CYFRA21-1升高组的患者总生存时间(overall survival, OS)少于术前正常组的患者,术前CYFRA21-1升高组差异有统计学意义(P=0.001)。与术前术后CEA、CYFRA21-1均正常等组的患者OS比较,术前术后CEA、CYFRA21-1均升高组的患者OS最短,两组差异均有统计学意义(P < 0.05)。与CEA联合CYFRA21-1术前术后均正常等组的患者OS比较,CEA联合CYFRA21-1术前术后均升高组的患者OS最短,差异有统计学意义(P < 0.001)。CEACYFRA21-1(HHHH)、CEACYFRA21-1(NNHH)、CYFRA21-1(HH)、CEA(HH)、男性是判断预后的独立危险因素(P < 0.05)。 结论 血清CEA或CYFRA21-1在手术前及术后均高于正常,尤其是两者联合在手术前及术后均升高的NSCLC患者预后不良。手术前后血清CEA、CYFRA21-1的检测有助于NSCLC患者术后预后的判断。

Abstract
Background Even after curative resection, the prognosis of pathological stage I non-small cell lung cancer (NSCLC) can be heterogeneous, and the use of adjuvant chemotherapy in these patients is controversial. We aimed to identify the prognostic factors and role of adjuvant chemotherapy in pathological stage I NSCLC. Methods We retrospectively analyzed the correlations between clinicopathological factors and survival in 179 patients with resected pathological stage I NSCLC. Results After a median follow-up of 93 months, overall and disease-free survival were not significantly different between pathological stage IA (n = 138) and IB (n = 41) patients. The prognosis of pathological stage I patients with poorly differentiated tumors was significantly worse than that of those with non-poorly differentiated tumors (P = 0.003). Multivariate analysis revealed that poor tumor differentiation was an independent factor for poor survival (hazard ratio = 6.889). A marginally significant survival benefit was observed in poorly differentiated pathological stage I patients who received adjuvant chemotherapy (P = 0.053). Pathological stage IA patients who received adjuvant chemotherapy had a worse prognosis than those who did not receive adjuvant chemotherapy (P < 0.001), whereas pathological stage IA patients with poorly differentiated tumors who received adjuvant chemotherapy had better survival than who did not receive adjuvant chemotherapy (P < 0.001). Conclusions Poor differentiation is an independent prognostic factor in pathological stage I NSCLC after surgical resection. Adjuvant chemotherapy may be beneficial in poorly differentiated pathological stage IA NSCLC patients.

Abstract
CXCR5 and/or CXCL13 expression is elevated in certain carcinomas and lymphomas. To determine if these factors are involved in progression of non-small cell lung cancer (LuCa), we evaluated their expression in patients with various forms of this disease. Lung biopsies from patients with non-neoplastic cells (n=8), squamous cell carcinoma (SCC; n=24), or adenocarcinoma (AC; n=54) were stained for CXCR5. Histopathological analysis of these samples showed significantly higher expression of CXCR5 (p<0.001) in carcinomas (i.e., SCCs and ACs) relative to non‑neoplastic lung tissue. Nuclear and membrane CXCR5 intensities were highest in ACs, with median values of 185 and 130, respectively, followed by SCCs with median values of 170 and 110, respectively. The lowest nuclear and membrane expressions of CXCR5 were found in non-neoplastic tissues, having median values of 142 and 90, respectively. Sera from SCC patients (n=17), AC patients (n=14), and healthy controls (n=9) were tested for the presence of CXCL13. Serum CXCL13 levels in LuCa patients were higher than in healthy controls. CXCR5 expression in cell lines of human non-small cell lung carcinoma (NCI-H1915) and small cell lung carcinoma (SW-1271) were evaluated by flow cytometry. CXCR5 expression was higher in NCI-H1915 cells relative to SW-1271 cells. The functional significance of CXCR5 expression was tested in a migration assay. In response to CXCL13, more NCI-H1915 cells migrated than SW-1271 cells. These findings suggest that the CXCR5‑CXCL13 axis influences LuCa progression. After validation in larger patient groups, CXCR5 and CXCL13 may prove useful as biomarkers for LuCa. Correspondingly, blockade of this axis could serve as an effective therapy for LuCa.

Abstract
The aim of the present study was to address the effects of heat shock protein B6 (HspB6) on tumor growth and metastasis in BALB/c mice. Lewis lung carcinoma (LLC) cells were subcutaneously injected into BALB/c mice followed by intraperitoneal injection of recombinant HspB6 (HspB6 groups) or phosphate‑buffered saline (control groups). Tumor growth and metastasis were assessed by size measurement and weighing of tumors and cervical lymph nodes, respectively. Chemokine expression in tumor masses was quantified quantitative polymerase chain reaction and western blotting. Tumor cell apoptosis was detected by flow cytometric analysis. The proliferation and migration of LLC cells, stimulated with HspB6, were detected using Cell Counting Kit 8 and wound scratch assays in vitro. Tumors grafted into the BALB/c mice and intraperitoneally injected with HspB6 were significantly bigger in size than those grafted into the control mice. From 7 days following the injection, the weight of cervical lymph nodes in HspB6 groups was higher than that in the control mice. We also revealed that the apoptotic cell number in tumor masses in the HspB6 groups was lower than that of the control mice. CD31 expression of vascular endothelial cells was higher in tumors grafted in HspB6 groups than those grafted in the control mice. Concomitantly, the tumor tissue mRNA and protein expression enhancement of vascular endothelial growth factor, basic fibroblast growth factor and intercellular adhesion molecule 1 were greater in HspB6 mice than in the control mice. HspB6 also inhibited cell apoptosis and enhanced the migration and proliferation of LLCs in vitro. In conclusion, HspB6 exhibited tumor promotion through increasing tumor angiogenesis, tumor metastasis and inhibiting tumor cell apoptosis.

Abstract
BACKGROUND T1 (≤ 3 cm) tumors with visceral pleural invasion (VPI) are upstaged to T2a (stage IB) in the TNM classification. We investigated the effect of VPI on the cumulative incidence of recurrence (CIR) and overall survival (OS) of lung adenocarcinoma (ADC) ≤ 2 cm (T1a) and 2 to 3 cm (T1b). METHODS OS and CIR among patients with or without VPI were examined by tumor size (≤ 2 and 2-3 cm) in 777 patients with node-negative lung ADC ≤ 3 cm who underwent resection. RESULTS Among patients with tumors ≤ 2 cm, VPI was not associated with either increased CIR (P = .90) or decreased OS (P = .11). Among patients with tumors 2 to 3 cm in size, the presence of VPI was associated with increased CIR (P = .015) and decreased OS (P < .001), even after adjusting for histologic subtype. When stage I lung ADCs ≤ 3 cm were regrouped as either new stage IA (≤ 2 cm with or without VPI, 2-3 cm without VPI) or new stage IB (2-3 cm with VPI), there was a statistically significant difference in 5-year CIR and OS between new stage IA and new stage IB tumors (CIR, 18% vs 40% [P = .004]; OS, 76% vs 51% [P < .001]). CONCLUSIONS VPI stratifies prognosis in patients with lung ADC 2 to 3 cm but not in those with tumors ≤ 2 cm. Our proposed regrouping of a new stage IB better stratifies patients with poor prognosis, similar to published outcomes in patients with stage II disease, who may benefit from adjuvant chemotherapy.

Abstract
BACKGROUND The non-small cell lung cancer (NSCLC) staging system (published in 2009 in the seventh edition of the cancer staging manuals of the Union for International Cancer Control and American Joint Commission on Cancer) did not include any changes to current N descriptors for NSCLC. However, the prognostic significance of the extent of lymph node (LN) involvement (including the LN zones involved [hilar/interlobar or peripheral], cancer-involved LN ratios [LNRs], and the number of involved LNs) remains unknown. The aim of this report is to evaluate the extent of LN involvement and other prognostic factors in predicting outcome after definitive surgery among Chinese patients with stage II-N1 NSCLC. METHODS We retrospectively reviewed the clinicopathologic characteristics of 206 patients with stage II (T1a-T2bN1M0) NSCLC who had undergone complete surgical resection at Shanghai Chest Hospital from June 1999 to June 2009. Overall survival (OS) and disease-free survival (DFS) were compared using Kaplan-Meier statistical analysis. Stratified and Cox regression analyses were used to evaluate the relationship between the LN involvement and survival. RESULTS Peripheral zone LN involvement, cancer-involved LNR, smaller tumor size, and squamous cell carcinoma were shown to be statistically significant indicators of higher OS and DFS by univariate analyses. Visceral pleural involvement was also shown to share a statistically significant relationship with DFS by univariate analyses. Multivariate analyses showed that tumor size and zone of LN involvement were significant predictors of OS. CONCLUSIONS Zone of N1 LN, LN ratios, and tumor size were found to provide independent prognostic information in patients with stage II NSCLC. This information may be used to stratify patients into groups by risk for recurrence.

Abstract
Previously, we reported that the overexpression of fer tyrosine kinase (FER), a non-receptor tyrosine kinase, is correlated with poor postoperative prognosis and cancer-cell survival in non-small cell lung cancer (NSCLC). In the present study, we further analyzed FER-overexpressed NSCLC cases and identified various patterns of chimeric mRNAs, composed of paraja ring finger 2 (PJA2) and FER. We detected no genomic rearrangements between PJA2 and FER and attributed these chimeric mRNAs to alterations at the transcriptome level: i.e., trans-splicing. Several chimeric patterns were detected concurrently in each patient, and the pattern sets varied among patients, although the pattern in which PJA2 exon 1 was fused to FER exon 3 (designated as Pe1-Fe3 mRNA) was detected constantly. Therefore, in a wide screening for PJA2-FER mRNAs in NSCLC, we focused on this chimeric pattern as a representative chimera. In analyses of 167 NSCLC samples, Pe1-Fe3 mRNA was identified in about 10% of the patients, and the presence of chimeric mRNA was significantly correlated with a high expression level of parental FER mRNA. Furthermore, we found that the detection of Pe1-Fe3 mRNA was correlated with poor postoperative survival periods in NSCLC, consistent with a previous finding in which FER overexpression was correlated with poor postoperative prognosis in NSCLC. This report is the first to suggest a correlation between chimeric mRNA and the expression level of parental mRNA. Furthermore, our findings may be clinically beneficial, suggesting that PJA2-FER mRNAs might serve as a novel prognostic biomarker in NSCLC.

Abstract
OBJECTIVE The objective of this study was to identify the clinicopathologic factors influencing postrecurrence survival (PRS) in and the effect of postrecurrence therapy (PRT) on patients with completely resected stage I non-small cell lung cancer (NSCLC). METHODS We reviewed the data of 919 patients in whom complete resection of stage I NSCLC had been performed. RESULTS Of the 919 patients, 170 (18.5%) had recurrent disease. Initial PRT was performed in 118 patients (69.1%) (surgery in eight, chemotherapy in 79, radiotherapy in 10, and chemoradiotherapy in 21). On multivariate analyses, PRT (hazard ratio [HR], 0.542; 95% CI, 0.344-0.853; P = .008), female sex (HR, 0.487; 95% CI, 0.297-0.801; P = .005), and differentiation (HR, 1.810; 95% CI, 1.194-2.743; P = .005) demonstrated a statistically significant association with favorable PRS. Bone metastasis (HR, 3.288; 95% CI, 1.783-6.062; P < .001), liver metastasis (HR, 4.518; 95% CI, 1.793-11.379; P = .001), chemotherapy (HR, 0.478; 95% CI, 0.236-0.975; P = .040), epidermal growth factor receptor-tyrosine kinase inhibitors treatment (EGFR-TKIs) (HR, 0.460; 95% CI, 0.245-0.862; P = .015), and nonadenocarcinoma (HR, 2.136; 95% CI, 1.273-3.585; P = .004) were independently and significantly associated with PRS in the 118 patients who underwent any PRT. Subgroup analysis with a combination of these five PRS factors in the patients who underwent any PRT revealed median PRS times of 42.4 months for 20 patients lacking all five risk factors and 18.8 months for 98 patients with at least one of these risk factors (P = .001). CONCLUSIONS PRT, sex, and differentiation were independently associated with PRS. In the patients who underwent any PRT, PRS was related to EGFR-TKIs, chemotherapy, histology, and initial recurrence sites. One challenge for the future will be to create systematic treatment strategies for recurrent NSCLC according to the risk factor status of individual patients.

Abstract
BACKGROUND Patients with completely resected non-small cell lung cancer (NSCLC) have an excellent outcome; however tumor recurs in 30%-77% of patients. This study retrospectively analyzed the clinicopathologic features of patients with any operable stage of NSCLC to identify the prognostic factors that influence tumor recurrence, including intratumoral blood vessel invasion (IVI), tumor size, tumor necrosis, and intratumoral lymphatic invasion. METHODS From January 2002 to December 2011, 227 consecutive patients were enrolled in this study. They were divided into two groups: the "no recurrence" group and the "recurrence" group. Recurrence-free survival was analyzed by multivariable Cox regression analysis, stratified by tumor staging, chemotherapy, and nodal involvement. RESULTS IVI, tumor necrosis, tumor diameter more than 5 cm, and nodal involvement were identified as independent prognostic factors of tumor recurrence. The hazard ratio (HR) of patients with IVI was 2.1 times higher than that of patients without IVI (95% confident interval [CI]: 1.4-3.2) (P = 0.001).The HR of patients with tumor necrosis was 2.1 times higher than that of patients without tumor necrosis (95% CI: 1.3-3.4) (P = 0.001). Patients who had a maximum tumor diameter greater than 5 cm had significantly higher risk of recurrence than patients who had a maximum tumor diameter of less than 5 cm (HR 1.9, 95% CI: 1.0-3.5) (P = 0.033). CONCLUSION IVI, tumor diameter more than 5 cm, and tumor necrosis are prognostic factors of tumor recurrence in completely resected NSCLC. Therefore, NSCLC patients, with or without nodal involvement, who have one or more prognostic factors of tumor recurrence may benefit from adjuvant chemotherapy for prevention of tumor recurrence.

Abstract
OBJECTIVES Even after curative resection, a significant fraction of patients with stage I non-small-cell lung cancer (NSCLC) die primarily because of systemic relapse. The purpose of the present study was to investigate the risk factors for both recurrence and poor survival in patients with pathological (p-) stage I NSCLC. METHODS We retrospectively reviewed 467 consecutive patients from a single institution with completely resected p-stage I NSCLC. Patients with multiple lung tumours or malignancies from other organs and those who had undergone preoperative therapies were excluded. The correlation between clinicopathological factors and surgical outcomes, including disease-free survival (DFS) and overall survival (OS), was analysed. The clinicopathological factors examined were age, gender, smoking history, serum carcinoembryonic antigen (CEA) levels, serum cytokeratin 19 fragment levels, surgical procedure, tumour histology, p-stage, angiolymphatic invasion and differentiation grade. RESULTS The 5-year DFS and OS rates of the total study population were 91.4 and 92.8%, respectively. Multivariate analysis results indicated that high serum CEA levels (>5.0 ng/ml) and p-stage IB were independent factors for recurrence, whereas older age (>70 years), high serum CEA levels and p-stage IB were independent factors for poor survival. The risks of recurrence and death in patients with both high serum CEA levels and p-stage IB was 10.3 and 5.2 times higher than those observed in patients with both normal serum CEA levels and p-stage IA, respectively. CONCLUSIONS High serum CEA levels and p-stage IB were independent factors for both recurrence and poor survival in p-stage I NSCLC patients.

Abstract
Background Lymphatic vessel invasion (LVI) exerts an important process in the progression and local spread of cancer cells. However, LVI as a prognostic factor for survival in non-small cell lung cancer (NSCLC) remains controversial. Methodology/Principal Findings A meta-analysis of published studies from PubMed and EMBASE electronic databases was performed to quantity the effects of LVI on both relapse-free survival and overall survival for patients with NSCLC. Hazard ratios (HRs) with 95% confidence intervals (95% CIs) were used to assess the strength of these effects. This meta-analysis included 18,442 NSCLC patients from 53 eligible studies. LVI appeared in 32.1% (median; range, 2.8% to 70.9%) of tumor samples. In all, patients with LVI were 2.48 times more likely to relapse by univariate analysis (95% CI: 1.92–3.22) and 1.73 times by multivariate analysis (95% CI: 1.24–2.41) compared with those without LVI. For the analyses of LVI and overall survival, the pooled HR estimate was 1.97 (95% CI: 1.75–2.21) by univariate analysis and 1.59 (95% CI: 1.41–1.79) by multivariate analysis. Multivariate analysis showed a risk was 91% higher for recurrence (HR = 1.91, 95% CI: 1.14–2.91) and 70% higher for mortality (HR = 1.70, 95% CI: 1.38–2.10) in LVI-positive I stage patients compared with LVI-negative I stage patients. Subgroup analyses showed similar significant adjusted risks for recurrence and death in adenocarcinomas, and a significant adjusted risk for death in studies that utilized elastic staining with or without immunohistochemistry in defining LVI. Conclusions/Significance The present study indicates that LVI appears to be an independent poor prognosticator in surgically managed NSCLC. NSCLC patients with LVI would require a more aggressive treatment strategy after surgery. However, large, well-designed prospective studies with clinically relevant modeling and standard methodology to assess LVI are required to address some of these important issues.

Re-evaluation of the prognostic value of visceral pleura invasion in Stage IB non-small cell lung cancer using the prospective multicenter ACOSOG Z0030 trial data set. Lung Cancer 2012; 78:259-62. [PMID: 23040416 DOI: 10.1016/j.lungcan.2012.09.010] [Citation(s) in RCA: 37] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2012] [Revised: 07/19/2012] [Accepted: 09/11/2012] [Indexed: 11/24/2022]
Abstract
PURPOSE This study seeks to clarify the modern prognostic significance of visceral pleura invasion (VPI) in Stage IB (T2aN0M0) non-small cell lung cancer (NSCLC) within the context of the 7th edition TNM classification using the data set from a recent prospective multicenter trial. PATIENTS AND METHODS 1111 early-stage NSCLC patients participating in the ACOSOG Z0030 trial (1990-2004) underwent curative pulmonary resection. After excluding T2b tumours (>5 cm and ≤ 7 cm) and non-size-based T2 factors other than VPI, 289 patients were categorized as Stage IB NSCLC - T2aN0M0 - according to the AJCC 7th edition classification. The patients were divided into three groups according to size and VPI: tumours ≤ 3 cm with VPI (Group I, "VPI-alone", n=83), tumours>3 cm and ≤ 5 cm without VPI (Group II, "Size-alone", n=156), and tumours>3 cm and ≤ 5 cm with VPI (Group III, "VPI+Size", n=50). Multivariate Cox regression analysis was used to assess the association of VPI and size with survival, adjusting for age, gender, histology and type of resection. RESULTS VPI in Stage IB was identified in 133 patients (46.0%). Survival analysis in these patients identified an optimal cutpoint for survival based on size of 3.1cm. Group III (VPI+Size) had a 5-year survival rate of 55.0% significantly shorter when compared to Group I (VPI-alone=68.3%, p=0.009), and Group II (Size-alone=67.2%, p=0.021). No difference was found between Groups I and II. Multivariable analysis showed that VPI associated with size was an independent negative prognostic factor of long-term survival, along with older age and limited resection. CONCLUSIONS Stage IB patients with VPI and tumours>3 cm and ≤ 5 cm have significantly worse prognosis than those with 'T2a' tumours on the basis of VPI or tumour size alone. This finding would suggest upstaging these patients from the current IB status to Stage IIA.

Abstract
OBJECTIVES Microvascular invasion and microlymphatic permeation are indicators of microscopic tumour invasion into small vessels and have been considered to be powerful prognostic indicators for non-small-cell lung cancer (NSCLC). Several studies have suggested that these should be included in the TNM classification, but, there have been conflicting results regarding the prognostic impact of microvascular invasion and microlymphatic permeation. The aim of the current study was to clarify the prognostic impact of microvascular invasion and microlymphatic permeation on resected node-negative NSCLC by comparative analyses. METHODS We reviewed the data of 1039 consecutive patients with pathological size-based stage T1a-3N0M0 NSCLC who underwent lobectomy or greater resection between 1993 and 2005. The median follow-up period was 108 months. Microvascular invasion and microlymphatic permeation were identified by the Victoria blue-van Gieson staining. The overall survival was then analysed. RESULTS Microvascular invasion and microlymphatic permeation were observed in 358 (34.5%) and 205 (19.7%) of patients, respectively. Both microvascular invasion and microlymphatic permeation were more prevalent in non-adenocarcinoma and larger-sized tumours. The 5-year overall survival rate of the microvascular invasion-positive group and microlymphatic permeation-positive group were 69.2 and 84.6%, respectively, and the difference was statistically significant (P = 0.002). On multivariate analyses, microvascular invasion, but not microlymphatic permeation, was an independent prognostic factor (microvascular invasion, hazard ratio [HR] 1.648, P = 0.001; microlymphatic permeation, HR 1.138, P = 0.588). The 5-year overall survival rate of either the microvascular invasion- or microlymphatic permeation-positive T1a-b group was significantly lower than that of the corresponding double-negative (dn) T1a-b group (dnT1a-b, 93.7%; microvascular invasion-positive T1a-b, 85.2%, P < 0.001; microlymphatic permeation-positive T1a-b, 85.4%, P = 0.014), and overlapped to that of the dnT2a group (84.8%). However, in the T2a-b group, only microvascular invasion-positive T2a-b patients showed significantly lower overall survival than dnT2a-b patients, and their overall survival overlapped that of dnT3 patients (dn T2a-b, 83.5%; microvascular invasion-positive T2a-b, 60.6%, P < 0.001; dnT3, 53.8%; P = 0.316). The 5-year overall survival of microlymphatic permeation-positive T2a-b patients (86.2%) did not statistically differ from that of dnT2a-b patients (P = 0.856). CONCLUSIONS Microvascular invasion and microlymphatic permeation have different impact on survival, and microvascular invasion rather than microlymphatic permeation is a strong prognostic factor in resected node-negative NSCLC. Microvascular invasion and microlymphatic permeation should be examined separately by elastic staining.

Abstract
We previously identified cathepsin D as a possible marker for lung adenocarcinoma (AD). The purpose of the present study is to evaluate the correlation between cathepsin D expression and clinicopathological findings or prognosis. We conducted immunohistochemistry (IHC) to assess 150 AD tissues. For these 150 tumors, TTF-1 expression, EGFR and KRAS gene mutations, and ALK rearrangements had already been examined. Cathepsin D expression was detected in 44% (66 of 150, IHC score ≥1+) and 27.3% (41 of 150, IHC score ≥2+). Cathepsin D-positive (IHC score ≥2+) tumors were more poorly differentiated than cathepsin D-negative ones, while all lepidic predominant invasive adenocarcinomas showed no cathepsin D expression. Univariate analysis revealed a poor prognosis for cathepsin D-positive lung AD patients with an IHC score ≥2+ (P=0.044). Cathepsin D expression was more frequent in TTF-1-negative than in TTF-1-positive ADs (P=0.034), and more frequent in ADs with EGFR wild genotype than mutant EGFR (P<0.001). Regarding AD patients with ALK rearrangements, 4 were positive for Cathepsin D, while 2 were negative. Cathepsin D expression is indicated to be a possible prognostic marker for lung AD and to correlate with a more poorly differentiated form.

Abstract
BACKGROUND In order to improve prognostic applications and treatment decisions, we report our experiences of visceral pleural surface invasion (VPSI) in non-small cell lung cancers (NSCLCs) with pleural retraction. METHODS A total of 321 NSCLCs with pleural retraction were identified by carefully inspecting surgically resected specimens. The extent of pleural invasion, including the use of elastic stain, was evaluated. Patients with and without VPSI were compared for clinicopathologic parameters and survival. RESULTS VPSI was identified in 170 (53.0 %) of the stage I-III cases and 98 (43.4 %) of the patients with stage I disease. VPSI was associated with a higher frequency of tumor size greater than 3 cm, moderate/poor differentiation, vascular invasion, mediastinal lymph node metastasis, extranodal involvement, and higher TNM stages. Multivariate analysis revealed VPSI to be a significant independent predictor of unfavorable prognosis. The 5-year survival of patients with and without VPSI was 57.9 and 83.0 %, respectively (P = 0.001), and was 74.3 and 88.5 % (P = 0.005) in stages I-III and stage I disease, respectively. CONCLUSIONS VPSI is an independent factor for poor prognosis in NSCLCs, regardless of lymph node status. Stage IB NSCLCs with PL1 pleural invasion are associated with a survival rate similar to that of stage IA NSCLCs and could be classified as T1 lesions. While surgical treatment is adequate in these patients, stage IB NSCLCs with VPSI have poor prognosis, and these patients should be considered for adjuvant chemotherapy.
