Ma S, Li Z, Wang L. The advanced lung cancer inflammation index (ALI) predicted the postoperative survival rate of patients with non-small cell lung cancer and the construction of a nomogram model. World J Surg Oncol 2024; 22:158. [PMID: 38877553 PMCID: PMC11177447 DOI: 10.1186/s12957-024-03432-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2024] [Accepted: 06/01/2024] [Indexed: 06/16/2024] Open
Abstract
OBJECTIVE To investigate the prognostic significance of the advanced lung cancer inflammation index (ALI) in patients with operable non-small-cell lung carcinoma (NSCLC). By constructing the nomogram model, it can provide a reference for clinical work. METHODS A total of 899 patients with non-small cell lung cancer who underwent surgery in our hospital between January 2017 and June 2021 were retrospectively included. ALI was calculated by body mass index (BMI) × serum albumin/neutrophil to lymphocyte ratio (NLR). The optimal truncation value of ALI was obtained using the receiver operating characteristic (ROC) curve and divided into two groups. Survival analysis was represented by the Kaplan-Meier curve. The predictors of Overall survival (OS) were evaluated by the Cox proportional risk model using single factor and stepwise regression multifactor analysis. Based on the results of multi-factor Cox proportional risk regression analysis, a nomogram model was established using the R survival package. The bootstrap method (repeated sampling 1 000 times) was used for internal verification of the nomogram model. The concordance index (C-index) was used to represent the prediction performance of the nomogram model, and the calibration graph method was used to visually represent its prediction conformity. The application value of the model was evaluated by decision curve analysis (DCA). RESULTS The optimal cut-off value of ALI was 70.06, and the low ALI group (ALI < 70.06) showed a poor survival prognosis. In multivariate analyses, tumor location, pathological stage, neuroaggression, and ALI were independently associated with operable NSCLC-specific survival. The C index of OS predicted by the nomogram model was 0.928 (95% CI: 0.904-0.952). The bootstrap self-sampling method (B = 1000) was used for internal validation of the prediction model, and the calibration curve showed good agreement between the prediction and observation results of 1-year, 2-year, and 3-year OS. The ROC curves for 1-year, 2-year, and 3-year survival were plotted according to independent factors, and the AUC was 0.952 (95% CI: 0.925-0.979), 0.951 (95% CI: 0.916-0.985), and 0.939 (95% CI: 0.913-0.965), respectively. DCA shows that this model has good clinical application value. CONCLUSION ALI can be used as a reliable indicator to evaluate the prognosis of patients with operable NSCLC, and through the construction of a nomogram model, it can facilitate better individualized treatment and prognosis assessment.

[PMID: 37561432 PMCID: PMC10546461 DOI: 10.1259/bjr.20230143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Revised: 07/03/2023] [Accepted: 07/11/2023] [Indexed: 08/11/2023] Open
Abstract
OBJECTIVE To validate selection criteria for sublobar resection in patients with lung cancer with respect to recurrence, and to investigate predictors for recurrence in patients for whom the criteria are not suitable. METHODS Patients who underwent sublobar resection for lung cancer between July 2010 and December 2018 were retrospectively included. The criteria for curative sublobar resection were consolidation-to-tumor ratio ≤0.50 and size ≤3.0 cm in tumors with a ground-glass opacity (GGO) component (GGO group), and size of ≤2.0 cm and volume doubling time ≥400 days in solid tumors (solid group). Cox regression was used to identify predictors for time-to-recurrence (TTR) in tumors outside of these criteria (non-curative group). RESULTS Out of 530 patients, 353 were classified into the GGO group and 177 into the solid group. In the GGO group, the 2-year recurrence rates in curative and non-curative groups were 2.1 and 7.7%, respectively (p = 0.054). In the solid group, the 2-year recurrence rates in curative and non-curative groups were 0.0 and 28.6%, respectively (p = 0.03). Predictors of 2-year TTR after non-curative sublobar resection were pathological nodal metastasis (hazard ratio [HR], 6.63; p = 0.02) and lymphovascular invasion (LVI; HR, 3.28; p = 0.03) in the GGO group, and LVI (HR, 4.37; p < 0.001) and fibrosis (HR, 3.18; p = 0.006) in the solid group. CONCLUSION The current patient selection criteria for sublobar resection are satisfactory. LVI was a predictor for recurrence after non-curative resection. ADVANCES IN KNOWLEDGE This result supports selection criteria of patients for sublobar resection. LVI may help predict recurrence after non-curative sublobar resection.

Lymph but Not Blood Vessel Invasion Is Independent Prognostic in Lung Cancer Patients Treated by VATS-Lobectomy and Might Represent a Future Upstaging Factor for Early Stages. Cancers (Basel) 2022; 14:cancers14081893. [PMID: 35454799 PMCID: PMC9031652 DOI: 10.3390/cancers14081893] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2022] [Revised: 04/02/2022] [Accepted: 04/06/2022] [Indexed: 12/04/2022] Open
Abstract
Lung cancer is the most frequent cause of cancer-related death worldwide. The patient’s outcome depends on tumor size, lymph node involvement and metastatic spread at the time of diagnosis. The prognostic value of lymph and blood vessel invasion, however, is still insufficiently investigated. We retrospectively examined the invasion of lymph vessels and blood vessels separately as two possible prognostic factors in 160 patients who underwent a video-assisted thoracoscopic lobectomy for non-small-cell lung cancer at our institution between 2014 and 2019. Lymph vessel invasion was significantly associated with the UICC stage, lymph node involvement, tumor dedifferentiation, blood vessel invasion and recurrence. Blood vessel invasion tended to be negative prognostic, but missed the level of significance (p = 0.108). Lymph vessel invasion, on the other hand, proved to be a prognostic factor for both histological subtypes, adenocarcinoma (p < 0.001) as well as squamous cell carcinoma (p = 0.018). After multivariate analysis apart from the UICC stage, only lymph vessel invasion remained independently prognostic (p = 0.018). Remarkably, we found analogue survival curve progressions of patients with stage I, with lymph vessel invasion, compared to stage II non-small-cell lung cancer. After further validation in prospective studies, lymph vessel invasion might be considered as an upstaging factor in resectable lung cancer. Especially in the early-stage of the disease, it might represent an additional risk factor to consider adjuvant therapy after surgical resection.

Prognostic impact of count of extratumoral lymphatic permeation in lung adenocarcinoma and its relation to immune microenvironment. Cancer Sci 2022; 113:1497-1506. [PMID: 35181964 PMCID: PMC8990291 DOI: 10.1111/cas.15267] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2021] [Revised: 12/24/2021] [Accepted: 01/04/2022] [Indexed: 11/28/2022] Open
Abstract
Extratumoral lymphatic permeation (ly‐ext) has been reported as an independent poor prognostic factor for lung adenocarcinoma, but whether or not the number of ly‐ext foci is associated with prognosis and its relationship to the immune microenvironment is unclear. We counted the number of ly‐ext foci on pathological slides from patients with completely resected lung adenocarcinoma with ly‐ext, and divided them into two groups: a group with a high number of ly‐ext foci (ly‐ext high) and one with a low number of ly‐ext foci (ly‐ext low). Among the patients with ly‐ext, only a high number of ly‐ext foci was an independent poor prognostic factor. The 3‐year recurrence‐free survival (RFS) rate of the ly‐ext high group was significantly lower than that of the ly‐ext low group (14.7% vs. 50.0%, P < 0.01). Then, we analyzed the immune microenvironment of pT1 lung adenocarcinoma with ly‐ext (13 cases of ly‐ext high and 11 cases of ly‐ext low tumor) by immunohistochemistry using antibodies for stem cell markers (aldehyde dehydrogenase 1 A1 and CD44), tumor‐promoting mucin (MUC1), tumor‐infiltrating lymphocytes (CD4, CD8, FOXP3, and CD79a), and tumor‐associated macrophages (CD204). The number of CD8+ TILs within the primary lesion was significantly lower and the number of FOXP3+ TILs within the primary lesion was significantly higher in the ly‐ext high group (P < 0.05 and P < 0.01, respectively). Our results indicated that a high number of ly‐ext foci was an independent poor prognostic factor. Moreover, tumors with high numbers of ly‐ext foci had a more immunosuppressive microenvironment.

[PMID: 33953608 PMCID: PMC8089025 DOI: 10.2147/cmar.s305179] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Accepted: 04/06/2021] [Indexed: 01/19/2023] Open
Abstract
Purpose Accumulating evidence has indicated that dysregulated microRNAs (miRNAs) are involved in cancer progression. In this study, we evaluated the clinicopathologic significance of miR-183-3p and miR-182-5p, and the role of miR-183-3p in non-small-cell lung cancer (NSCLC) progression. Patients and Methods Seventy-six NSCLC patients from Beijing Chest Hospital were included. The expression of miR-183-3p and miR-182-5p was evaluated by real-time quantitative polymerase chain reaction (RT-qPCR). Then, cell growth curve assays and colony formation assays were performed. Bioinformatics analysis of TCGA database was performed to explore the clinicopathological significance and prognostic value. Results miR-183-3p and miR-182-5p were significantly increased in NSCLC tumor tissues (both P < 0.0001) and were positively correlated (r = 0.8519, P < 0.0001). miR-183-3p (P = 0.0444) and miR-182-5p (P = 0.0132) were correlated with tumor size. In addition, miR-183-3p (P = 0.0135) and miR-182-5p (P = 0.0009) were upregulated in normal lung tissues from smokers. In vitro, miR-183-3p was correlated with cell proliferation. In addition, bioinformatics analysis indicated that miR-183-3p was correlated with poor prognosis (P = 0.0466) and tumor size (P = 0.0017). In addition, miR-183-3p was higher in lung squamous carcinoma (LUSC) tissue (P < 0.0001) than in lung adenocarcinoma (LUAD) tissue, and miR-183-3p was higher in the tumor tissue of smokers (P = 0.0053) than in that of nonsmokers. Conclusion Upregulation of miR-183-3p and miR-182-5p may play an oncogenic role in NSCLC. miR-183-3p could be used as a potential prognostic biomarker and therapeutic target to manage lung cancer.

Abstract
After several decades without maintained responses or long-term survival of patients with lung cancer, novel therapies have emerged as a hopeful milestone in this research field. The appearance of immunotherapy, especially immune checkpoint inhibitors, has improved both the overall survival and quality of life of patients, many of whom are diagnosed late when classical treatments are ineffective. Despite these unprecedented results, a high percentage of patients do not respond initially to treatment or relapse after a period of response. This is due to resistance mechanisms, which require understanding in order to prevent them and develop strategies to overcome them and increase the number of patients who can benefit from immunotherapy. This review highlights the current knowledge of the mechanisms and their involvement in resistance to immunotherapy in lung cancer, such as aberrations in tumor neoantigen burden, effector T-cell infiltration in the tumor microenvironment (TME), epigenetic modulation, the transcriptional signature, signaling pathways, T-cell exhaustion, and the microbiome. Further research dissecting intratumor and host heterogeneity is necessary to provide answers regarding the immunotherapy response and develop more effective treatments for lung cancer.

Comparison of prognostic impact of lymphovascular invasion in stage IA non-small cell lung cancer after lobectomy versus sublobar resection: A propensity score-matched analysis. Lung Cancer 2020; 146:105-111. [PMID: 32526600 DOI: 10.1016/j.lungcan.2020.04.033] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2020] [Revised: 04/23/2020] [Accepted: 04/27/2020] [Indexed: 11/19/2022]
Abstract
OBJECTIVES Lymphovascular invasion (LVI) is a well-known poor prognostic factor after lobectomy for non-small cell lung cancer. However, the prognostic effect of LVI in patients who undergo sublobar resection has not been fully evaluated. Thus, we compared the prognostic impact of LVI in stage IA patients who underwent lobectomy or sublobar resection. MATERIALS AND METHODS We retrospectively reviewed the data from patients with stage IA NSCLC who underwent surgical resection between 2007 and 2016. The prognostic impact of LVI was calculated by the Cox proportional hazard regression model. To adjust for the differences in confounding variables between LVI-positive and LVI-negative patients, propensity score matching (PSM) was carried out in patients who underwent lobectomy or sublobar resection. RESULTS Among the stage IA NSCLC patients (n = 2134), 184 (8.6%) had been diagnosed with LVI, of whom 144 (8.9%) were in the lobectomy group (n = 1614) and 40 (7.7%) were in the sublobar resection group (n = 520). In multivariable analysis, LVI was a significant risk factor for both overall survival (OS) (hazard ratio [HR], 2.03; 95% confidence interval [CI], 1.39-2.96; p < 0.001) and recurrence-free survival (RFS) (HR, 2.31; 95% CI, 1.68-3.17; p < 0.001). After PSM, the prognostic impact of LVI was greater in the sublobar resection group (HR = 4.93 and 4.25 for OS and RFS, respectively) than in the lobectomy group (HR = 1.77 and 2.51 for OS and RFS, respectively). CONCLUSIONS The presence of LVI was significantly associated with worse OS and RFS in stage IA NSCLC patients. The prognostic impact of LVI was more pronounced in the sublobar resection group than in the lobectomy group.

Abstract
BACKGROUND The optimal treatment of stage I non-small-cell lung carcinoma is subject to debate. The aim of this study was to compare overall survival and oncologic outcomes of lobar resection (LR), sublobar resection (SR), and stereotactic body radiotherapy (SBRT). METHODS A systematic review and meta-analysis of oncologic outcomes of propensity matched comparative and noncomparative cohort studies was performed. Outcomes of interest were overall survival and disease-free survival. The inverse variance method and the random-effects method for meta-analysis were utilized to assess the pooled estimates. RESULTS A total of 100 studies with patients treated for clinical stage I non-small-cell lung carcinoma were included. Long-term overall and disease-free survival after LR was superior over SBRT in all comparisons, and for most comparisons, SR was superior to SBRT. Noncomparative studies showed superior long-term overall and disease-free survival for both LR and SR over SBRT. Although the papers were heterogeneous and of low quality, results remained essentially the same throughout a large number of stratifications and sensitivity analyses. CONCLUSION Results of this systematic review and meta-analysis showed that LR has superior outcomes compared to SBRT for cI non-small-cell lung carcinoma. New trials are underway evaluating long-term results of SBRT in potentially operable patients.

METHODS A total of 3,177 patients with non-small cell lung cancer at the Beijing Cancer Hospital were classified based on the following three methods: (I) the N descriptors in the 8th edition of the TNM classification system: N0, N1, N2, and N3; (II) the IASLC-proposed N subgroups: N1a, N1b, N2a1, N2a2, and N2b; (III) our more extensive division method: N1a, N1b, N1c, N2a1, N2a2, N2b1, N2b2, N2c, N3a, and N3b. Five-year survival analysis was performed using the Kaplan-Meier method, and differences between subgroups were evaluated using the log-rank test. RESULTS (I) A significant survival difference was found between each adjacent N descriptor; (II) the difference between each adjacent subgroup N descriptor was significant, but the difference between N1b and N2a1 was not; (III) in our proposed method, a significant difference was found between all the subgroups apart from N2a2 and N2b1, N2b1 and N2b2, N2c and N3a, and N3a and N3b. CONCLUSIONS The N descriptors in the 8th edition of the tumor, node, and metastasis (TNM) classification system are consistent with our data. Although our more extensive division method could distinguish between patients at different stages, its implementation is complicated; thus, we recommend the implementation of the IASLC-proposed subgroups with the addition of the N1b and N2a1 groups.

Prediction of Postoperative Clinical Outcomes in Resected Stage I Non-Small Cell Lung Cancer Focusing on the Preoperative Glasgow Prognostic Score. Cancers (Basel) 2020; 12:cancers12010152. [PMID: 31936329 PMCID: PMC7016624 DOI: 10.3390/cancers12010152] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2019] [Revised: 01/04/2020] [Accepted: 01/06/2020] [Indexed: 02/07/2023] Open
Abstract
Background: The Glasgow Prognostic Score (GPS), which consists of albumin and C-reactive protein (CRP), may predict overall survival (OS) in cancer patients. The aim of this retrospective analysis was to evaluate the clinical impact of the preoperative GPS on patients with resected early stage non-small cell lung cancer (NSCLC). Methods: 300 patients with curatively resected stage I NSCLC were followed-up for OS, recurrence-free survival (RFS), cancer-specific survival (CSS), and death from other causes. Results: 229 patients (76%) had a preoperative GPS of 0, and 71 (24%) a GPS ≥ 1. The three-year probabilities of RFS, OS, CSS, and death from other causes were 81%, 84%, 88%, and 96% in patients with GPS = 0, and 79%, 74%, 91%, and 82% in patients with a GPS ≥ 1, respectively. GPS ≥ 1 was significantly associated with a higher risk of death from other causes (p = 0.022), serving as an independent predictor of death from other causes (p = 0.034). Pathologically elevated CRP levels (CRP > 5 mg/L) were found in 91 patients (30%). The mean CRP level was 7.88 ± 15.80 mg/L (0.5–135.6 mg/L). Pre-treatment CRP level was significantly associated with coronary heart disease (p < 0.0001), histology (p = 0.013), tumor size (p = 0.018), tumor stage (p = 0.002), and vascular invasion (p = 0.017). Conclusion: The preoperative GPS predicts adverse survival outcomes in patients with resected stage I NSCLC.

Abstract
BACKGROUND Recent studies have indicated that solid predominant (SP) subtype of lung adenocarcinoma (LADC) may be associated with early recurrence and worse prognosis. Hence, a systematic review and meta-analysis were performed to evaluate the association between LADC subtype and survival. METHODS The MEDLINE, SCOPUS, Web of Science and Cochrane Libraries were reviewed for eligible studies in December 2017. Studies were included if they compared outcomes of patients with and without SP subtype in resection specimens of LADC patients after surgical treatment by using multivariate Cox regression analysis. A meta-analysis for overall survival (OS) and disease-free survival (DFS) was performed. The hazard ratios (HR) or odds ratios with 95% confidence intervals (CIs) from each study were used to calculate pooled HRs. Statistical analyses were performed using Review Manager 5.3. RESULTS In total, 14 eligible studies including 12,137 LADC patients were identified, which assessed the impact of SP subtype on OS and DFS in patients treated with pulmonary resection. SP subtype was reported in 1246 (10.2%) patients and was associated with significantly worse OS (pooled HR, 1.51; 1.29-1.75) and DFS (pooled HR, 1.26; 1.14-1.40). CONCLUSIONS SP subtype is associated with significantly worse OS and DFS in patients with LADC after pulmonary resection. These data provide evidence for the integration of the distinct histological LADC subtyping into prognostic tools and guidelines for adjuvant treatment after complete surgical resection.

Abstract
BACKGROUND Lung cancer harboring epidermal growth factor receptor (EGFR) mutations and treated with EGFR tyrosine kinase inhibitors (TKIs) all eventually develop acquired resistance to the treatment, with half of the patients developing EGFR T790M resistance mutations. OBJECTIVE The purpose of this study was to assess histological and clinical characteristics and survival outcomes in Hispanic EGFR mutated lung cancer patients after disease progression. PATIENTS AND METHODS EGFR mutation-positive lung cancer patients (n = 34) with acquired resistance to the EGFR-TKI erlotinib were identified from 2011 to 2015. Post-progression tumor specimens were collected for molecular analysis. Post-progression interventions, response to treatment, and survival were assessed and compared among all patients and those with and without T790M mutations. RESULTS Mean age was 59.4 ± 13.9 years, 65% were never-smokers, and 53% had a performance status 0-1. All patients received erlotinib as first-line treatment. Identified mutations included: 60% DelE19 (Del746-750) and 40% L858R. First-line erlotinib overall response rate (ORR) was 61.8% and progression free survival (PFS) was 16.8 months (95% CI: 13.7-19.9). Acquired resistance mutations identified were T790M mutation (47.1%); PI3K mutations (14.7%); EGFR amplification (14.7%); KRAS mutation (5.9%); MET amplification (8.8%); HER2 alterations (5.9%, deletions/insertions in e20); and SCLC transformation (2.9%). Of patients, 79.4% received treatment after progression. ORR for post-erlotinib treatment was 47.1% (CR 2/PR 14) and median PFS was 8.3 months (95% CI: 2.2-36.6). Median overall survival (OS) from treatment initiation was 32.9 months (95% CI: 30.4-35.3), and only the use of post-progression therapy affected OS in a multivariate analysis (p = 0.05). CONCLUSIONS Hispanic patients with acquired resistance to erlotinib continued to be sensitive to other treatments after progression. The proportion of T790M+ patients appears to be similar to that previously reported in Caucasians.

Abstract
The clinical outcomes of patients with early-stage non-small cell lung cancer (NSCLC) have remained unsatisfactory after complete surgical resection. The objective of this study was to explore the prognostic value of matrix metalloproteinase 9 (MMP9) activity level in Chinese patients with stage I B lung adenocarcinoma. A sensitive and validated method was employed for determining the activity of MMP9 in human lung adenocarcinoma cells in vitro. Then, the association was examined between the level of MMP9 enzymatic activity and clinical outcomes. A total of 104 cases were stratified according to the IASLC/ATS/ERS classification scheme and activity of MMP9 was analyzed by SensoLyte® assay kit. The results showed that the MMP9 activity was the highest in solid predominant and micropapillary predominant subtypes, intermediate in acinar predominant and papillary predominant subtypes, and the lowest in lepidic predominant subtype. Multivariate analysis revealed that pathological subtype and activity of MMP9 were independent prognostic factors for disease-free survival (DFS), respectively (P = 0.005 and 0.029). Significant relationship existed between enzyme activity of MMP9 and prognosis. And the 30 months DFS of high- and low-level MMP9 activity tumors was 44.2% and 84.1% (P < 0.0001), respectively. High-level MMP9 activity is correlated with aggressive tumor behaviors and poor clinical outcomes in early-stage lung adenocarcinoma after complete resection.

Abstract
PURPOSE Controversy remains exist for the effect of adjuvant chemotherapy (ACT) among stage IB lung adenocarcinoma patients. This study aimed to investigate the predictive value of the current lung adenocarcinoma classification system on benefit of ACT among patients with stage IB lung adenocarcinoma. METHODS A total of 928 pathological stage IB invasive adenocarcinoma patients with R0 resection were included in this study. Based on the predominant growth pattern present in the tumor, invasive adenocarcinomas with mixed histologic components were classified into five subtypes: lepidic (LEP), acinar (ACN), papillary (PAP), micropapillary (MIP) and solid (SOL). These five histologic subtypes were collapsed into three groups (LEP, ACN/PAP and SOL/MIP). Disease-free survival (DFS) and overall survival (OS) were analyzed to evaluate benefit from ACT in patients with different histologic patterns using the Kaplan-Meier approach and multivariable Cox models. RESULTS For all stage IB invasive adenocarcinoma patients, SOL/MIP subgroup presented the worst prognosis, and LEP subgroup showed approximately 100 % 5-year survival. ACT was associated with a better DFS (HR, 0.70; 95 % CI 0.51-0.96, p = .026) for all stage IB patients. In SOL/MIP subgroup, patients could benefit from ACT for a significant improved DFS (HR, 0.81; 95 % CI 0.49-1.35; p = .030), but not for OS (HR, 0.39; 95 % CI 0.12-1.30, p = .111). In ACN/PAP subgroup, there was no significant benefit from ACT for both DFS (HR, 0.76; 95 % CI 0.54-1.08, p = .125) and OS (HR, 0.81; 95 % CI 0.49-1.35, p = .421). CONCLUSIONS SOL/MIP predominant pattern was predictive for ACT benefit for DFS among invasive lung adenocarcinoma patients in stage IB.

Abstract
The morbidity and mortality of lung cancer rank the first place among all the malignant tumor. According to the histopathological characteristics, lung cancer is divided into non-small cell lung cancer (NSCLC) and small cell lung cancer. Only 20% patients diagnosed with NSCLC have the chance for surgery while their 5-yr overall survival is about 30%-60%. The therapeutic outcome of surgery alone is not satisfying. Adjuvant chemotherapy after surgical resection in stage II-IIIa lung cancer showed efficacy in many randomized clinical trials, but its role in stage I disease remains controversial. The choice of appropriate chemotherapy candidates, the selection of chemotherapy regimens and the research progress on biomarker are mainly discussed in this review.

Abstract
INTRODUCTION In TNM classification, factors determining the tumor (T) component in non-small cell lung cancer have scarcely changed over time and are still based solely on anatomical features. Our objective was to study the influence of these and other morphopathological factors on survival. METHODS A total of 263 patients undergoing lung resection due to stage I non-small cell lung cancer ≤3cm in diameter were studied. A survival analysis and competing-risk estimate study was made on the basis of clinical, surgical and pathological variables using actuarial analysis and accumulative incidence methods, respectively. A risk model was then generated from the results. RESULTS Survival at 5 and 10 years was 79.8 and 74.3%, respectively. The best prognostic factors were presence of symptoms, smoking habit and FEV1>60%, number of resected nodes>7, squamous histology, absence of vascular invasion, absence of visceral pleural invasion and presence of invasion more proximal than the lobar bronchus. All these were statistically significant according to the actuarial method. The factor "age<50 years" was close to the margin of statistical significance. Pleural invasion and vascular invasion were entered in the multivariate analysis. The competing-risk analysis showed a probability of death due to cancer of 14.3 and 35.1% at 5 and 10 years, respectively. Significant variables in the univariate and multivariate analyses were similar, with the exception of FEV1>60%. CONCLUSIONS Pleural invasion and vascular invasion determine survival or risk of death due to non-small cell lung cancer ≤3cm and can be used for generating a predictive risk model.

Abstract
BACKGROUND AND OBJECTIVE Survival studies of non-small cell lung cancer (NSCLC) are usually based on the Kaplan-Meier method. However, other factors not covered by this method may modify the observation of the event of interest. There are models of cumulative incidence (CI), that take into account these competing risks, enabling more accurate survival estimates and evaluation of the risk of death from other causes. We aimed to evaluate these models in resected early-stage NSCLC patients. PATIENTS AND METHOD This study included 263 patients with resected NSCLC whose diameter was ≤ 3 cm without node involvement (N0). Demographic, clinical, morphopathological and surgical variables, TNM classification and long-term evolution were analysed. To analyse CI, death by another cause was considered to be competitive event. For the univariate analysis, Gray's method was used, while Fine and Gray's method was employed for the multivariate analysis. RESULTS Mortality by NSCLC was 19.4% at 5 years and 14.3% by another cause. Both curves crossed at 6.3 years, and probability of death by another cause became greater from this point. In multivariate analysis, cancer mortality was conditioned by visceral pleural invasion (VPI) (P=.001) and vascular invasion (P=.020), with age>50 years (P=.034), smoking (P=.009) and the Charlson index ≥ 2 (P=.000) being by no cancer. CONCLUSIONS By the method of CI, VPI and vascular invasion conditioned cancer death in NSCLC >3 cm, while non-tumor causes of long-term death were determined.

Abstract
Introduction: Lymphatic permeation has been reported as a prognostic factor for patients with resected non–small-cell lung cancer (NSCLC). Lymphatic canals are located in both intratumoral and extratumoral areas. Since 2001, we have prospectively evaluated lymphatic permeation based on its location. The purpose of this study was to determine the survival impact of extratumoral lymphatic permeation in patients with resected NSCLC by analyzing the long-term follow-up data. Methods: We reviewed 1069 consecutive patients with NSCLC who underwent complete resection between 2001 and 2006. Lymphatic permeation was classified as follows: ly0, absence of lymphatic permeation; ly1, intratumoral; and ly2, extratumoral. Results: There were 845 patients (79%) with ly0, 134 (12%) with ly1, and 90 (9%) with ly2. Ly2 was more frequently observed in patients with advanced disease and intrapulmonary metastases than ly0–1. The 5-year overall survival (OS) rates of the ly0, ly1, and ly2 groups were 75%, 63%, and 34%, respectively. The OS rate was significantly worse in the ly2 group compared with OS rate in the ly0 (p < 0.01) and ly1 groups (p < 0.01). In multivariate analyses, ly2 proved to be an independent poor prognostic factor (hazard ratio, 1.73; p < 0.01). OS and recurrence-free survival of patients with T1 and T2 tumors with ly2 were not statistically different from that of the patients with T3 tumor (OS, p = 0.43 and p = 0.77; recurrence-free survival, p = 0.94 and p = 0.94, respectively). Conclusions: The adverse prognostic impact of lymphatic permeation was remarkably different whether it is detected in intratumoral or extratumoral lymphatic canals. We recommend that lymphatic permeation in resected NSCLC should be evaluated by considering its location.

Abstract
Non-small-cell lung cancer (NSCLC) has entered the age of individual treatment, and increasing point mutations of specific oncogenes and rearrangement of some chromosomes are biomarkers used to predict the therapeutic effect of targeted therapy. At present, there is a consensus among clinicians that epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have shown favorable efficacy in NSCLC patients with EGFR mutation, and some relevant research has suggested that the presence of EGFR mutations is a favorable prognostic marker. However, the association of EGFR mutation status with the responsiveness to conventional chemotherapy agents and survival in NSCLC patients is still unclear. This review provides an overview of and assesses the role of EGFR as a prognostic marker for postoperative patients and as a predictive marker for response to cytotoxic chemotherapy. In addition, we review the comparison of response to chemotherapy between EGFR mutations in exon 19 and in exon 21 and the predictive role of p.T790M mutation.

Abstract
Background A new lung adenocarcinoma classification proposed by the International Association for the Study of Lung Cancer, American Thoracic Society, and European Respiratory Society (IASLC/ATS/ERS) has recently been published. This study aimed to investigate the utility of the new histological classification for identifying the prognostic subtypes of adenocarcinomas in stage IB patients.Correlations between the classification and the presence of epidermal growth factor receptor (EGFR) mutation status was also studied. Methods One hundred and thirty-six patients with stage IB lung adenocarcinoma operated on in Zhejiang Cancer Hospital were identified between 2002 and 2011. Patients overall survival and disease-free survival were calculated using Kaplan-Meier and Cox regression analyses. EGFR mutations were detected using the amplification refractory mutation system. Results A total of 136 cases were included in current study, of which 38 were papillary predominant, 39 were acinar predominant, 22 were micropapillary predominant, 21 were lepidic predominant subtypes, 14 were solid predominant, and 2 were variants of invasive adenocarcinoma. Patients with micropapillary- and solid-predominant tumors had the lowest five-year disease-free survival (28.4 and 36.7%, respectively). Univariate and multivariate analysis showed that the micropapillary-predominant subtype was an independent predictor of disease-free survival (P = 0.0041 and 0.048, respectively), but not overall survival (P = 0.175 and 0.214, respectively). EGFR mutations were significantly associated with the micropapillary-predominant subtype patients (P = 0.0026). The EGFR mutation frequency is lower in the solid-predominant subtype than other subtypes (P = 0.0508). Conclusions The predominant subtype in the primary tumor was associated with prognosis in resected stage IB lung adenocarcinoma. The EGFR mutation frequency of micropapillary-predominant subtype is higher than other subtypes.

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 7th TNM staging system for non-small cell lung cancer (NSCLC) developed by the International Association for the study of Lung Cancer (IASLC) has been applied in Sweden since the beginning of the year 2010. The aim of this retrospective study was to evaluate the prognostic role of the 7th TNM staging system in a surgical Swedish patient cohort with node-negative NSCLC. MATERIAL AND METHODS We collected data from stage I patients (pT1-2 pN0, 6th TNM system) who underwent surgery for NSCLC at Karolinska University Hospital from 1987 to 2002. Tumors were restaged according to the 7th TNM version. Cox multivariate survival analysis was implemented in order to determine the prognostic impact of pathological stage when classified according to either the 6th or the 7th TNM systems. RESULTS The patient population consisted of 452 subjects. Tumor size was ≤ 3 cm in 51% of cases. The predominant histology was adenocarcinoma (53%) and lobectomy was the most common surgical procedure (82% of patients). The five-year survival rate in patients with stage IA vs. IB (6th TNM) was 62% vs. 51%, respectively (log-rank p = 0.036). Corresponding figures for the 7th TNM system were 70% in stage IA-T1a, 51% in stage IA-T1b, 54% in stage IB, 51% in stage IIA and 35% in stage IIB (log-rank p = 0.002). On multivariate analysis, adjusted by age, gender, histology, kind of surgery, grade of differentiation and smoking status, pathological stage was an independent prognostic factor if classified according to the 7th TNM version (p = 0.001), but not if scored according to the 6th TNM edition (p = 0.090). CONCLUSION The 7th TNM classification system is a more accurate predictor of prognosis in stage I operated patients than the old classification. The new system should be implemented even on retrospective cohorts especially when investigating the prognostic implication of the expression of molecular biomarkers.

Abstract
Novel biomarkers are required to improve prognostic predictions obtained with lung cancer staging systems. This study of 62 surgically-treated Non-Small Cell Lung Cancer (NSCLC) patients had two objectives: i) to compare the predictive value of T-stage classifications between the 6(th) and 7(th) editions of the Tumor, Node, and Metastasis staging system (TNM); and ii) to examine the association of Pkp1 and/or Krt15 gene expression with survival and outcomes. Multivariate and Kaplan-Meier survival analyses were performed, examining the relationship of survival with T-stage, recurrence, and TNM-stage (by each TNM edition) and with the single/combined expression of Pkp1 and/or Krt15 genes. Five-year survival rates only significantly differed as a function of T-stage in patients without recurrence when estimated using the 6(th) edition of the TNM classification and only in patients in pathologic TNM-stage IA using the 7(th). Overall survival for patients with elevated expression of both genes was 13.5 months in those with adenocarcinoma and 34.6 months in those with squamous cell carcinoma. Overall survival was 30.4 months in patients with Pkp1 gene upregulation and 30.9 months in those with Krt15 gene upregulation. In conclusion, survival estimations as a function of T-staging differed between the 6(th) and 7(th) editions of TNM. Overall survival differed according to the expression of Pkp1 and/or Krt15 genes, although this relationship did not reach statistical significance.

Abstract
BACKGROUND: Auto-fluorescence bronchoscopy (AFB) has been used for the identification and localization of intra-epithelial pre-neoplastic and neoplastic lesions within the bronchus. OBJECTIVES: To determine the applicability of AFB for the detection and localization of precancerous and cancerous lesions, in addition to analyzing the morphologic presentation, their association to histological type and the variation between genders. METHODS: A five-year study involving 4983 patients, who underwent routine bronchoscopy [B] examination in a local tertiary teaching hospital, was done. The B examination was performed under intratracheal lidocaine, and samples were obtained using suitable approach. One thousand four hundred and eighty-five pathologically confirmed lung cancer patients were included in the study. The following parameters were studied: Morphological presentation, biopsy sites, histology. Differences between the groups were analyzed using Chi square test. RESULT: One thousand four hundred and eighty-five patients who had hyperplasia or neoplastic lesions were further confirmed as lung cancer pathologically. Lung cancer was more commonly found in the right lung (51.58% vs. 42.82%). The lesion occurred more frequently in the upper lobe than the lower lobe (44.17% vs. 22.42%). Male patients with squamous cell carcinoma showed upper lobe involvement more commonly, while the left main bronchus was more commonly involved in female patients. Adenocarcinoma mostly involved lesion of the upper lobe. Squamous cell carcinoma and small cell carcinoma were the major proliferative types (80.15% and 76.16% respectively). CONCLUSION: AFB is efficient in the detection of pre-invasive and invasive lung lesions. The morphological presentation is associated to the histological type. There is variation in the presentation and histology of cancerous lung lesions between genders.

Abstract
The purpose of this research was to study the roles of chloride intracellular channel protein 1 (CLIC1) and heat shock protein 27 (HSP27) in the clinical pathology of lung adenocarcinoma and to explore whether the expression of CLIC1 and HSP27 can be used as independent factors for the prediction of recurrence and prognosis after radical resection of lung adenocarcinoma. One hundred and three paraffin sections of lung adenocarcinoma tissues were collected, and the expression of CLIC1 and HSP27 was detected in these tumors using immunohistochemistry. The correlation of the expression of these two proteins with clinicopathological parameters and prognosis was statistically analyzed. In the 103 samples, the expression of HSP27 and CLIC1 was strongly positive in 61 (59.2%) and 49 cases (47.6%), respectively. Statistical analysis showed that the expression level of HSP27 did not significantly correlate with the patient's age, sex, degree of tumor differentiation, T staging of tumors, and TNM staging of tumors (p > 0.05), whereas the expression of CLIC1 did significantly correlate with T staging of tumors (p = 0.029). Univariate analysis indicated that the patient's ECOG score, T staging, N staging, TNM staging, and CLIC1 expression correlated with prognosis (p = 0.031, 0.001, 0.011, 0.013, and <0.001, respectively). Multivariate statistical analysis showed that age, T staging, and CLIC1 expression were independent associated factors for predicting the 5-year survival rate of patients (p = 0.026, 0.004, and <0.001, respectively). Age, T staging, and CLIC1 expression significantly correlated with the overall survival of post-operative lung adenocarcinoma patients. CLIC1 may be closely associated with the occurrence and development of lung adenocarcinoma and may be used as an effective marker for predicting the prognosis of this disease.

Abstract
The aim of the study was to evaluate the double modality working of a new autofluorescence videobronchoscope SAFE-3000 for the detection and localization of precancerous and malignant lesions. From April to May 2009, 168 patients underwent SAFE-3000 bronchoscopy using 'Twin Mode' and 'Multiple Image Xposition (MIX)' technologies. The study considers only 97 patients with morphological alterations (visual score 2 or 3) of mucosa; four bronchial biopsies (two for every modality) have been performed on every patient. Histological diagnosis of the 388 biopsies revealed normal mucosa in 11 patients, four benign lesions, 27 precancerous lesions and 55 malignant lesions. The sensitivity of the 'Twin Mode' and 'MIX' techniques in the characterization of premalignant and malignant lesions was 96% vs. 100%. The specificity was 60% in both of these technologies. SAFE-3000 autofluorescence bronchoscopy allows an early diagnosis of preneoplastic or neoplastic lesions according to the careful analysis of the bronchial mucosa, due to the complementarity of two modalities 'Twin Mode' and 'MIX'. Based on the relationship between the bronchoscopic goal and the histological results the MIX method contributes more of the new endoscopic technique findings.

Abstract
BACKGROUND This study investigated poor prognostic factors in patients with stage IB non-small cell lung cancer (NSCLC) according to the seventh edition of the TNM classification. METHODS Between July 1992 and December 2004, 1,204 consecutive patients with stage I NSCLC diagnosed based on the sixth edition TNM classification underwent complete resection with systematic node dissection. Of these patients, 434 were reclassified as stage IB according to the seventh edition TNM classification. Univariate analyses were performed using the log-rank test to select prognostic factors. The Cox proportional hazards regression model was used for multivariate analyses to identify independent factors indicating an unfavorable prognosis. RESULTS On multivariate analyses, two variables were independent significant factors indicating an unfavorable prognosis: presence of intratumoral vascular invasion and presence of visceral pleural invasion. According to subgroup analyses combining these two risk factors, 5-year disease-specific survival probabilities were 93%, 83%, and 73% for patients with zero, one, or two risk factors, respectively. The 5-year disease-specific survival of patients without risk factors was not statistically different from that of patients with stage IA cancer. In addition, the 5-year disease-specific survival curve of patients with two risk factors lay beneath that of patients with T2b or T3N0M0, stage II cancer, and there were no statistically significant differences between them. CONCLUSIONS We identified the presence of intratumoral vascular invasion and the presence of visceral pleural invasion as independent poor prognostic factors in patients with stage IB NSCLC. When these two factors are combined, higher- and lower-risk subgroups can be identified, which will help to personalize adjuvant chemotherapy.

Abstract
背景与目的 新的第7版非小细胞肺癌(non-small cell Lung cancer, NSCLC)分期已经提出肿瘤直径对NSCLC预后的重要性,但是对癌灶直径≤2 cm预后研究尚少。本研究旨在探讨影响癌灶≤2 cm(T1a)的Ⅰ期NSCLC病人的临床预后因素,为临床预后治疗提供依据。 方法 回顾性分析本院既往手术后病理诊断为癌灶≤2 cm(T1a)的Ⅰ期的73例NSCLC病人,运用统计学软件SPSS 17.0分析影响长期生存的临床因素。 结果 该类患者5年以上总体生存率达到80.8%。性别(P=0.175)、年龄(P=0.241)、病理类型(P=0.265)、是否行系统纵隔淋巴结清扫手术(P=0.918)、是否术后辅助化疗(P=0.616)、是否侵犯胸膜(P=0.827)和该类患者的长期生存无明显相关性。影响预后的主要因素是癌灶的分化程度,即在中度分化程度以下长期生存较差(P=0.01)。 结论 在癌症直径≤2 cm的Ⅰ期肺癌中,侵犯胸膜对生存无影响,而分化程度是一个重要的独立预后因素。

Abstract
Despite an increasing use of chemotherapy in the palliative setting for lung cancer, the role of palliative thoracic radiotherapy should not be disregarded. It offers quick and efficient palliation, with improvement observed in approximately two-thirds of treated patients. There is evidence that the short and long radiotherapy schedules are equally effective for poor performance patients. Higher radiation doses delivered via protracted schedules give a modest survival benefit for good performance patients. The current review covers the issues related to the use of palliative thoracic radiotherapy, such as total dose, fractionation, delayed versus immediate use, external-beam radiotherapy versus endobronchial brachytherapy, combination with chemotherapy, re-irradiation and palliation with radiation in small-cell lung cancer.
