Role of invasive mediastinal nodal staging in survival outcomes of patients with non-small cell lung cancer and without radiologic lymph node metastasis: a retrospective cohort study. EClinicalMedicine 2024; 69:102478. [PMID: 38361994 PMCID: PMC10867420 DOI: 10.1016/j.eclinm.2024.102478] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2023] [Revised: 01/19/2024] [Accepted: 01/25/2024] [Indexed: 02/17/2024] Open
Abstract
Background Lung cancer diagnostic guidelines advocate for invasive mediastinal nodal staging (IMNS), but the survival benefits of this approach in patients with non-small cell lung cancer (NSCLC) without radiologic evidence of lymph node metastasis (rN0) remain uncertain. We aimed to investigate the impact of IMNS in patients with rN0 NSCLC by comparing the long-term survival between patients who underwent IMNS and those who did not (non-IMNS). Methods In this retrospective cohort study, we included patients with NSCLC but without radiologic evidence of lymph node metastasis from the Registry for Thoracic Cancer Surgery and the clinical data warehouse at the Samsung Medical Centre, Republic of Korea between January 2, 2008 and December 31, 2016. We compared the 5-year overall survival (OS) rate as the primary outcome after propensity score matching between the IMNS and non-IMNS groups. The age, sex, performance statue, tumor size, centrality, solidity, lung function, FDG uptake in PET-CT, and histological examination of the tumor before surgery were matched. Findings A total of 4545 patients (887 in the IMNS group and 3658 in the non-IMNS group) who received curative treatment for NSCLC were included in this study. By the mediastinal node dissection, the overall incidence of unforeseen mediastinal node metastasis (N2) was 7.2% (317/4378 patients). Despite the IMNS, 67% of pathological N2 was missed (61/91 patients with unforeseen N2). Based on propensity score matching, 866 patients each for the IMNS and non-IMNS groups were assigned. There was no significant difference in 5-year OS and recurrence-free survival (RFS) between two groups: 5-year OS was 73.9% (95% confidence interval, CI: 71%-77%) for IMNS and 71.7% (95% CI: 68.6%-74.9%; p = 0.23), for non-IMNS (hazard ratio, HR 0.90, 95% CI: 0.77-1.07), while 5-year RFS was 64.7% (95% CI: 61.5%-68.2%) and 67.5% (95% CI: 64.3%-70.9%; p = 0.35 (HR 1.08, 95% CI: 0.92-1.27), respectively. Moreover, the timing and locations of recurrence were similar in both groups. Interpretation IMNS might not be required before surgery for patients with NSCLC without LN suspicious of metastasis. Further randomised trials are required to validate the findings of the present study. Funding None.

Abstract
OBJECTIVES The proper procedure for inferior pulmonary ligament (IPL) during upper lobectomy remains a topic of debate. To address this matter, we carried out a trial comparing the clinical outcomes of IPL preservation versus IPL dissection during thoracoscopic upper lobectomy (TUL). METHODS Patients undergoing thoracoscopic left/right upper lobectomy (TLUL/TRUL) were assigned to either the dissection group (Group D) or the preservation group (Group P). Our primary objective was to quantify and compare the alterations in postoperative residual bronchial angle and lung volume changes between the two groups. Our secondary objective encompassed the assessment of various other intraoperative and postoperative outcomes. RESULTS Following adherence to the inclusion and exclusion criteria, we enrolled 100 patients (41 left and 59 right) in Group P and 108 patients (41 left and 67 right) in Group D for the study. Our findings revealed that in TLUL, Group P was able to reduce the degree of postoperative residual bronchial angle change (P < 0.05). Conversely, the situation was distinct for TRUL. We found no notable disparity between the two groups (P > 0.05) with regard to alterations in lung volume or the occurrence of postoperative complications-except for the duration of postoperative hospital stay (P < 0.05). CONCLUSIONS Our study suggests IPL preservation especially for TLUL when compared to TRUL, which have important implications for the clinical management of patients undergoing upper lobectomy.

Abstract
BACKGROUND This study compares the surgical and long-term outcomes, including disease-free survival (DFS), overall survival (OS), and cancer-specific survival (CSS), between lobe-specific lymph node dissection (L-SND) and systematic lymph node dissection (SND) among patients with stage I non-small cell lung cancer (NSCLC). METHODS In this retrospective study, 107 patients diagnosed with clinical stage I NSCLC undergoing video-assisted thoracic surgery lobectomy (exclusion of the right middle lobe) from January 2011 to December 2018 were enrolled. The patients were assigned to the L-SND (n = 28) and SND (n = 79) groups according to the procedure performed on them. Demographics, perioperative data, and surgical and long-term oncological outcomes were collected and compared between the L-SND and SND groups. RESULTS The mean follow-duration was 60.6 months. The demographic data and surgical outcomes and long-term oncological outcomes were not significantly different between the two groups. The 5-year OS of the L-SND and SND groups was 82% and 84%, respectively. The 5-year DFS of the L-SND and SND groups was 70% and 65%, respectively. The 5-year CSS of the L-SND and SND groups was 80% and 86%, respectively. All the surgical and long-term outcomes were not statistically different between the two groups. CONCLUSION L-SND showed comparable surgical and oncologic outcomes with SND for clinical stage I NSCLC. L-SND could be a treatment choice for stage I NSCLC.

Abstract
BACKGROUND One-third of non-small cell lung cancer (NSCLC) patients are diagnosed with locally advanced disease. Long-term survival in stage IIIA/B-N2 remains poor; this may also be due to lymph node spreading pattern. Therefore, we compared the overall survival of stage IIIA/B-N2 patients with superior mediastinal lymph nodes (SML) with infracarinal- or inferior mediastinal lymph nodes (IML) and with multilevel disease (MLD). RESEARCH DESIGN AND METHODS One-, three-and five-year survival rates were measured. Kaplan-Meier curves and Cox proportional hazards model assessed survival and were used to identify prognostic factors. RESULTS We reviewed data of stage IIIA/B-N2 patients (n = 129) who underwent surgery for NSCLC between 2012 and 2020. Patients with SML (n = 62) were compared to ILM (n = 37) and MLD (n = 30). SML patients showed significantly better one- (SML: 95.2% vs. IML: 78.6% vs. MLD: 69.4%, p = 0.03), three- (78.8% vs. 27.7 vs. 13.3%; p = <0.001) and five-year (61.1% vs. 17.1 vs. 3%; p < 0.001) survival rates, than IML and MLD patients. Kaplan-Meier curves showed prolonged overall survival for SML patients (log-rank SML, ILM, MLD p < 0.0001). CONCLUSIONS This study showed significantly better long-term survival of SML patients than IML and MLD patients. The long-term survival of ILM and MLD patients was equally poor.

Abstract
Lymph node dissection is a vital part of surgical treatment for early-stage non-small cell lung cancer (NSCLC). Lobectomy with systematic lymph node dissection (SLND) still remains the gold standard surgical treatment for early-stage NSCLC patients. However, an increasing number of studies have demonstrated that lobe-specific lymph node dissection (L-SLND) can be used as an alternative therapy for SLND in carefully selected patients with early-stage NSCLC. However, there are no currently available evidences of review summarizing the role of L-SLDN in treating early-stage NSCLC. Therefore, we performed this literature review by summarizing the existing literatures on the lymph node drainage pattern, definition, scope and role of L-SLND in patients with early-stage NSCLC, aiming to provide evidence for the application of L-SLND in patients with early-stage NSCLC.

Abstract
Background Whether 4L lymph node dissection (LND) should be performed remains unclear and controversial. Prior studies have found that station 4L metastasis was not rare and that 4L LND may provide survival benefits. The objective of this study was to analyze the clinicopathological and survival outcomes of 4L LND from the perspective of histology. Methods This retrospective study included 74 patients with squamous cell carcinoma (SCC) and 84 patients diagnosed with lung adenocarcinoma (ADC) between January 2008 and October 2020. All patients underwent pulmonary resection with station 4L LND and were staged as T1-4N0-2M0. Clinicopathological features and survival outcomes were investigated based on histology. The study endpoints were disease-free survival (DFS) and overall survival (OS). Results The incidence rate of station 4L metastasis was 17.1% (27/158) in the entire cohort, with 8.1% in the SCC group, and 25.0% in the ADC group. No statistical differences in the 5-year DFS rates (67.1% vs. 61.7%, P=0.812) and 5-year OS rates (68.6% vs. 59.3%, P=0.100) were observed between the ADC group and the SCC group. Multivariate logistic analysis revealed that histology (SCC vs. ADC: OR, 0.185; 95% CI, 0.049-0.706; P=0.013) was independently associated with 4L metastasis. Multivariate survival analysis showed that the status of 4L metastasis was an independent factor for DFS (HR, 2.563; 95% CI, 1.282-5.123; P=0.008) but not for OS (HR, 1.597; 95% CI, 0.749-3.402; P=0.225). Conclusion Station 4L metastasis is not rare in left lung cancer. Patients with ADC have a greater predilection for station 4L metastasis and may benefit more from performing 4L LND.

Patterns of nodal spread in stage III NSCLC: importance of EBUS-TBNA and 18F-FDG PET/CT for radiotherapy target volume definition. Radiat Oncol 2021; 16:176. [PMID: 34526050 PMCID: PMC8442338 DOI: 10.1186/s13014-021-01904-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2021] [Accepted: 08/30/2021] [Indexed: 12/25/2022] Open
Abstract
Purpose The aim of this study was to compare the pattern of intra-patient spread of lymph-node (LN)-metastases within the mediastinum as assessed by 18F-FDG PET/CT and systematic endobronchial ultrasound-guided transbronchial-needle aspiration (EBUS-TBNA) for precise target volume definition in stage III NSCLC. Methods This is a single-center study based on our preceding investigation, including all consecutive patients with initial diagnosis of stage IIIA-C NSCLC, receiving concurrent radiochemotherapy (12/2011–06/2018). Inclusion criteria were curative treatment intent, 18F-FDG PET/CT and EBUS-TBNA prior to start of treatment. The lymphatic drainage was classified into echelon-1 (ipsilateral hilum), echelon-2 (ipsilateral LN-stations 4 and 7) and echelon-3 (rest of the mediastinum, contralateral hilum). The pattern of spread was classified according to all permutations of echelon-1, echelon-2, and echelon-3 EBUS-TBNA findings. Results In total, 180 patients were enrolled. Various patterns of LN-spread could be identified. Skip lesions with an involved echelon distal from an uninvolved one were detected in less than 10% of patients by both EBUS-TBNA and PET. The pattern with largest asymmetry was detected in cases with EBUS-TBNA- or PET-positivity at all three echelons (p < 0.0001, exact symmetry test). In a multivariable logistic model for EBUS-positivity at echelon-3, prognostic factors were PET-positivity at echelon-3 (Hazard ratio (HR) = 12.1; 95%-CI: 3.2–46.5), EBUS-TBNA positivity at echelon-2 (HR = 6.7; 95%-CI: 1.31–31.2) and left-sided tumor location (HR = 4.0; 95%-CI: 1.24–13.2). There were significantly less combined ipsilateral upper (LN-stations 2 and 4) and lower (LN-station 7) mediastinal involvements (16.8% of patients) with EBUS-TBNA than with PET (38.9%, p < 0.0001, exact symmetry test). EBUS-TBNA detected a lobe specific heterogeneity between the odds ratios of LN-positivity in the upper versus lower mediastinum (p = 0.0021, Breslow-Day test), while PET did not (p = 0.19). Conclusion Frequent patterns of LN-metastatic spread could be defined by EBUS-TBNA and PET and discrepancies in the pattern were seen between both methods. EBUS-TBNA showed more lobe and tumor laterality specific patterns of LN-metastases than PET and skipped lymph node stations were rare. These systematic relations offer the opportunity to further refine multi-parameter risk of LN-involvement models for target volume delineation based on pattern of spread by EBUS-TBNA and PET.

NAN FANG YI KE DA XUE XUE BAO = JOURNAL OF SOUTHERN MEDICAL UNIVERSITY 2020; 40:1793-1798. [PMID: 33380404 PMCID: PMC7835698 DOI: 10.12122/j.issn.1673-4254.2020.12.14] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Indexed: 12/25/2022]
Abstract
OBJECTIVE To analyze the clinicopathological characteristics and risk factors of 4L lymph node metastasis in left non-small cell lung cancer. METHODS We retrospectively analyzed the data of 134 patients undergoing surgical resection of left non-small cell lung cancer and 4L lymph node dissection, including 60 patients with squamous cell carcinoma (SCC) and 74 with lung adenocarcinoma (ADC). The clinicopathological characteristics of the patients were analyzed, and logistic regression analysis was used to identify the predictors of station 4L metastasis. RESULTS Of these patients, 16.4% (22/134) presented with station 4L metastasis. The patients with SCC and ADC showed significant differences in age, gender, smoking history, neoadjuvant chemotherapy, tumor size, tumor location and type, visceral pleural invasion, Ki-67 index, 4L metastasis and pathological TNM stage (stage Ⅱ). The rate of station 4L metastasis was significantly lower in SCC group than in ADC group. Univariate analysis revealed that pathological types (SCC or ADC), visceral pleural invasion, lymphovascular invasion, tumor markerabnormality, and station 5 to 10 metastasis were all high-risk factors for station 4L metastasis. Multivariate analysis suggested that the pathological type (OR=0.120, P=0.025), station 5 metastasis (OR=18.784, P=0.007) and station 10 metastasis (OR=5.233, P=0.044) were independent risk factors for 4L metastasis in patients with left non-small cell lung cancer. CONCLUSIONS In patients with left non-small cell lung cancer, station 4L metastasis is not rare and is more likely to occur in patients with lung adenocarcinoma. Dissection of the 4L lymph nodes should be performed in cases with low risk of damages of the adjacent tissues and high risk of station 4L metastasis.

Machine learning-based diagnostic method of pre-therapeutic 18F-FDG PET/CT for evaluating mediastinal lymph nodes in non-small cell lung cancer. Eur Radiol 2020; 31:4184-4194. [PMID: 33241521 DOI: 10.1007/s00330-020-07523-z] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Revised: 09/08/2020] [Accepted: 11/16/2020] [Indexed: 12/11/2022]
Abstract
OBJECTIVES We aimed to find the best machine learning (ML) model using 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) for evaluating metastatic mediastinal lymph nodes (MedLNs) in non-small cell lung cancer, and compare the diagnostic results with those of nuclear medicine physicians. METHODS A total of 1329 MedLNs were reviewed. Boosted decision tree, logistic regression, support vector machine, neural network, and decision forest models were compared. The diagnostic performance of the best ML model was compared with that of physicians. The ML method was divided into ML with quantitative variables only (MLq) and adding clinical information (MLc). We performed an analysis based on the 18F-FDG-avidity of the MedLNs. RESULTS The boosted decision tree model obtained higher sensitivity and negative predictive values but lower specificity and positive predictive values than the physicians. There was no significant difference between the accuracy of the physicians and MLq (79.8% vs. 76.8%, p = 0.067). The accuracy of MLc was significantly higher than that of the physicians (81.0% vs. 76.8%, p = 0.009). In MedLNs with low 18F-FDG-avidity, ML had significantly higher accuracy than the physicians (70.0% vs. 63.3%, p = 0.018). CONCLUSION Although there was no significant difference in accuracy between the MLq and physicians, the diagnostic performance of MLc was better than that of MLq or of the physicians. The ML method appeared to be useful for evaluating low metabolic MedLNs. Therefore, adding clinical information to the quantitative variables from 18F-FDG PET/CT can improve the diagnostic results of ML. KEY POINTS • Machine learning using two-class boosted decision tree model revealed the highest value of area under curve, and it showed higher sensitivity and negative predictive values but lower specificity and positive predictive values than nuclear medicine physicians. • The diagnostic results from machine learning method after adding clinical information to the quantitative variables improved accuracy significantly than nuclear medicine physicians. • Machine learning could improve the diagnostic significance of metastatic mediastinal lymph nodes, especially in mediastinal lymph nodes with low 18F-FDG-avidity.

Abstract
OBJECTIVE to validate the proposed N descriptor revision on a large cohort of patients and assess the impact of tumour location on the distribution pattern of lymph node metastases for patients with NSCLC. METHODS This is a retrospective review of a consecutive series of patients who had anatomical lung resections. Systematic lymph node dissection was done for all patients. RESULTS Between January 2009 and December 2019 2566 patients had surgical resection for NSCLC. 448 patients (17.5%) had histologically confirmed lymph node metastases: 257 (57.4 %) had pN1 and 191 pN2. Median age of the study population was 69.1 years. Overall survival (OS) for study population was 37.3 months with 5-year survival rate of 35.7 %. The survival analysis of the N subgroups showed the pN2 patients had a median OS of 27.9 months vs. 41.7 months for pN1 patients (p = 0.013). Analysis as per the new proposal of the N subgroups N1a vs N1b vs N2a1 vs N2a2 vs N2b showed that median survival OS was 41.7 vs. 39.2 mo vs. 33.3 mo vs. 28.9 mo vs. 24.6 mo (p = 0.099). There was statistically significant difference in survival between N2 patients with skip metastasis and N2 patients without skip metastases: OS 32.2 (95 % CI: 16.8-47.6) months vs. 24.2 months (p = 0.024). On multivariate analysis only pathological N (p = 0.011) and the new proposed N classification (p = 0.006) were independent prognostic factors for survival. CONCLUSIONS N1 and N2 disease are heterogeneous groups and require further stratification. The number of N2 lymph node stations involved and the presence or not of N1 disease translated to significant differences in survival and therefore have to be included in N staging.

Lobe-specific Lymph Node Dissection in Clinical Stage IA Solid-dominant Non-small-cell Lung Cancer: A Propensity Score Matching Study. Clin Lung Cancer 2020; 22:e201-e210. [PMID: 33187913 DOI: 10.1016/j.cllc.2020.09.012] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Revised: 07/08/2020] [Accepted: 09/23/2020] [Indexed: 01/30/2023]
Abstract
BACKGROUND Lobectomy with systematic lymph node dissection (SND) remains the standard procedure for resectable non-small-cell lung cancer (NSCLC), whereas lobe-specific lymph node dissection (LSND) was reported to have more advantages in perioperative recovery and complication reduction in treating early-stage diseases. Survival outcomes after LSND remains controversial compared with SND. PATIENTS AND METHODS From 2014 to 2017, data of 546 patients with clinical stage IA solid-dominant NSCLC and who underwent curative lobectomies with LSND (n = 100) or SND (n = 446) at our institution were collected. Propensity score matching was conducted to eliminate the biases. Five-year disease-free survival and overall survival were compared between the groups. Perioperative parameters and postoperative complications were also analyzed. RESULTS Lobectomies with LSND or SND were performed in 100 patients and 446 patients, respectively. After matching, there were 100 patients in each group and no significant differences in 5-year overall survival (P = .473) and disease-free survival (P = .789) were found between the groups. Recurrence patterns were also similar (P = .733). Perioperative parameters were similar, whereas the incidence of postoperative complications in the SND group was found to be significantly higher than that in the LSND group (P = .003). CONCLUSIONS Our study demonstrated that LSND has similar efficiency to SND in terms of survival, recurrence, lymph node dissection, and perioperative recovery of patients with clinical stage IA solid-dominant NSCLC, as well as significant advantages in reducing postoperative complications. Therefore, curative lobectomies with LSND may be more suitable and practical for clinical stage IA solid-dominant patients with NSCLC.

Abstract
Background: Lymph node metastasis (LNM) status is critical to the treatment. Fewer studies has focused on LNM in patients with small-size non-small cell lung cancer (NSCLC). This study aims to investigate clinicopathological characteristics associated with skip N2 (SN2) and non-skip N2 (NSN2) metastasis, and their metastatic patterns in NSCLC with tumor size of 1–2 cm. Methods: We reviewed the records of NSCLC patients with tumor size of 1–2 cm who underwent lobectomy with systematic lymph node dissection (LND) between January 2013 and June 2019. Clinical, radiographical, and pathological characteristics were compared among N1, SN2, and NSN2 groups. Metastatic patterns of mediastinal lymph node were analyzed based on final pathology. Results: A total of 63 NSCLC patients with tumor size of 1–2 cm were staged as pN2, including 25 (39.7%) SN2 and 38 (60.3%) NSN2. The incidence rates of SN2 and NSN2 were 2.8% (25/884) and 4.3% (38/884), respectively. For all clinicopathological characteristics, no significant difference was observed among the groups of N1, SN2, and NSN2. For the tumor located in each lobe, specific nodal drainage stations were identified: 2R/4R for right upper lobe; 2R/4R and subcarinal node (#7) for right middle lobe and right lower lobe; 4L and subaortic node (#5) for left upper lobe; #7 for left lower lobe. However, there were still a few patients (10.9%, 5/46) had the involvement of lower zone for tumors of upper lobe and the involvement of upper zone for lower lobe. Conclusions: SN2 occurs frequently in patients with small-size NSCLC. Whether lobe-specific selective LND is suitable for all small-size patients deserves more studies to confirm. Surgeons should be more careful when performing selective LND for tumors located in the lower and upper lobes.

Abstract
PURPOSE The purpose of this study was to investigate lymph node involvement pattern in clinical stage IA non-small cell lung cancer (NSCLC). PATIENTS AND METHODS Clinical stage ⅠA NSCLC patients who underwent lobectomy and lymph node resection were included in this retrospective study. Mediastinal lymph node involvement was distinguished by different lobes and tumor size. RESULTS From 2000 to 2015, a total of 759 patients were identified: 282 (37.2%) with tumors in the right upper lobe (RUL), 183 (24.1%) in the left upper lobe (LUL), 124 (16.3%) in the right lower lobe (RLL), 103 (13.6%) in the left lower lobe (LLL), and 67 (8.8%) in the right middle lobe (RML). Patients with tumor size ≤1 cm accounted for 19.6%, >1 and ≤2 cm for 47.8%, >2 and ≤3 cm for 32.5%. Patients with pN1 accounted for 8.2%, and pN2 for 12.5%. Among patients with pN2, the inferior mediastinum was involved in 9.7% of RULs and 17.4% of LULs; the superior mediastinum was involved in 52.2% of RLLs and 36.4% of LLLs. Mediastinal lymph node metastasis was found in 13.2% of patients with size >1 and ≤2 cm, and 19.0% of >2 and ≤3 cm. Patients with tumors ≤1 cm had no N2 lymph node involved. CONCLUSION Selective lymph node dissection based on tumor location is not recommended in clinical stage ⅠA NSCLC, and systemic lymph node dissection should be performed for NSCLC with size >1 cm.

Abstract
Abstract
OBJECTIVES
We investigated the impact of level 4 (L4) lymph node dissection (LND) on overall survival (OS) in left-side resectable non-small-cell lung cancer (NSCLC), with the aim of guiding lymphadenectomy.
METHODS
A total of 1929 patients with left-side NSCLC who underwent R0 resection between 2001 and 2014 were included in the study. The patients were divided into a group with L4 LND (L4 LND+) and a group without L4 LND (L4 LND−). Propensity score matching was applied to minimize selection bias. The Kaplan–Meier method and Cox proportional hazards model were used to assess the impact of L4 LND on OS.
RESULTS
A total of 317 pairs were matched. Of the cohort of patients, 20.3% (391/1929) had L4 LND. Of these patients, 11.8% (46/391) presented with L4 lymph node metastasis. L4 lymph node metastasis was not associated with the primary tumour lobes (P = 0.61). Before propensity score matching, the 5-year OS was comparable between the L4 LND+ and L4 LND− groups (69.0% vs 65.2%, P = 0.091). However, after propensity score matching, the 5-year OS of the L4 LND+ group was much improved compared to that of the L4 LND− group (72.9% vs 62.3%, P = 0.002) and L4 LND was an independent factor favouring OS (hazard ratio 0.678, 95% confidence interval 0.513–0.897; P = 0.006). Subgroup analysis suggested that L4 LND was an independent factor favouring OS in left upper lobe tumours.
CONCLUSIONS
In patients with left-side operable NSCLC, L4 lymph node metastasis was not rare and L4 LND should be routinely performed.

Abstract
Purpose This study aims to explore whether lobe specific lymph node dissection (LND) is adequate for cN0–1 non-small cell lung cancer (NSCLC) or not. Methods Among 5613 cN0–1 NSCLC patients, 394 cases (7.0%) with pN2 were enrolled and the distribution of mediastinal lymph node metastasis was analyzed. The included patients were divided into the non-lobe specific lymph node metastasis (NLSLNM) group and the lobe specific lymph node metastasis (LSLNM) group. The clinicopathological characteristics were compared between two groups and multivariable analysis was performed to find independent factors predicting NLSLNM. Results The incidence of pN2 cases deserved serious attention. The proportion of upper zone lymph node metastases was not rare in right (55.0%) and left (35.7%) lower lobe tumors. The proportion of subcarinal zone lymph node involvement was also high in right (21.8%) and left (25.8%) upper lobe tumors. Multivariable analysis showed that elevated carcinoembryonic antigen (CEA) level (P = 0.034), right lower lobe (RLL) tumors (P = 0.022) and station 11 involvement (P = 0.030) were independent risk factors for NLSLNM. Conclusion Systematic LND seems to be superior to lobe specific LND in the assessment of lymph node status and high CEA level, RLL tumors and station 11 involvement are predictors for NLSLNM.

Abstract
OBJECTIVE To develop a method for analysis of lymphatic drainage pathways from the lobe of the lung affected by non-small cell lung cancer (NSCLC) using infrared fluorescence. MATERIAL AND METHODS A study enrolled patients with NSCLC who underwent anatomic resection of the lung with systematic lymph node dissection and preliminary intraoperative peritumoral injection of indocyanine green conjugate with human albumin. Registration of fluorescence in regional lymph nodes (LN) was carried out immediately after excision of specimen using the FLUM-808 instrumental system. RESULTS Infrared fluorescence was observed in 117 hilar and mediastinal lymph nodes from 43 patients (2.7 nodes per a patient). Comparison of localization of fluorescent LN with localization of tumor in various lobes established significant variability of lymphatic drainage pathways. CONCLUSION The developed method of infrared fluorescent evaluation of lymphatic drainage in patients with NSCLC confirms the necessity of systematic lymph node dissection for adequate staging.

Abstract
OBJECTIVES The requirement to divide an inferior pulmonary ligament (IPL) during an upper lobectomy has not been standardized. We evaluated the influence of the division of an IPL after a lobectomy of the right upper lobe. METHODS We evaluated 52 patients with lung cancer who underwent a video-assisted thoracoscopic lobectomy of the right upper lobe at Asan Medical Center between January 2011 and April 2014. These cases were stratified by division of the IPL or not, i.e. a preservation group (group P, n = 21) and a division group (group D, n = 31). The angle between the bronchus intermedius and the right middle lobe bronchus and the lung volume were measured using computed tomography. The results of the pulmonary function tests and the prevalence of complications were also reviewed. RESULTS The prevalences of atelectasis (P = 0.538), dead space (P = 0.084) and pleural effusion (P = 0.538) were not statistically different. The postoperative volumetric change of the right middle lobe (group P, -27 ± 97 ml; group D, -29 ± 111 ml; P = 0.950) and of the right lower lobe (group P, 397 ± 293 ml; group D, 335 ± 294 ml; P = 0.459) did not show statistical differences. The change in the bronchial angle was not statistically different between the groups (group P, -26.3 ± 13.7°; group D, -26.7 ± 13.6°; P = 0.930). The patients in group D experienced a greater loss in forced vital capacity than those in group P (group P, -0.16 ± 0.26 l; group D, -0.42 ± 0.33 l; P = 0.007), but the loss in the forced expiratory volume in 1 s was not significant (P = 0.328). CONCLUSIONS An IPL division does not produce significant differences in lung volume, bronchial angle change or prevalence of complications other than loss of forced vital capacity.

Abstract
BACKGROUND The necessity of the inferior pulmonary ligament (IPL) dissection after an upper lobectomy remains controversial. This meta-analysis aimed to evaluate whether this accessional procedure could reduce the postoperative complications and improve outcomes. METHODS PubMed, Embase, Ovid, Cochrane Library, CBM, and CNKI databases were searched for the relevant studies which compared the dissection with preservation of IPL during the upper lobectomy. The Review Manager 5.3 software was used for this meta-analysis. RESULTS Three RCTs and five CCTs were included in this meta-analysis. These studies contained a total of 610 patients, in which 315 patients received a pulmonary ligament dissection (group D) after the upper lobectomy, while the other 295 patients preserved the pulmonary ligament (group P). No significant difference was demonstrated between the group D and group P in terms of drainage time after surgery (MD 0.14, 95%CI - 0.05 to 0.33, P = 0.15), rate of postoperative dead space (OR 1.33, 95%CI 0.72 to 2.46, P = 0.36), rate of postoperative complications (OR 1.20, 95%CI 0.66 to 2.19, P = 0.56). However, the pooled comparison revealed a greater change of the right main bronchial angle (MD 5.00, 95%CI 1.68 to 8.33, P = 0.003) in group D compared with group P, indicated that the dissection of IPL may lead to a greater distortion of bronchus. CONCLUSIONS This meta-analysis confirmed that the dissection of IPL do not effectively reduce the postoperative complications and improve the prognosis. Therefore, it is not necessary to dissect the IPL after an upper lobectomy.

Abstract
OBJECTIVES
Our goal was to investigate the incidence and distribution of mediastinal lymph node metastases (MLNM) in non-small-cell lung cancers (NSCLC) 3 cm or less, with the purpose of guiding mediastinal lymph node dissection.
METHODS
A total of 2292 cases seen between January 2001 and December 2014 were included. These patients were grouped according to the lobes with the primary tumours. The incidence and distribution of pathological MLNM were compared among the groups. The impact of MLNM on overall survival was also compared.
RESULTS
The most common mediastinal metastatic sites for different primary tumour lobes were as follows: right upper lobe, 17.7% (87/492) for level 4R; right middle lobe, 14.9% (28/188) for level 7; right lower lobe, 19.8% (82/414) for level 7; left upper lobe, 18.2% (96/528) for level 5; and left lower lobe, 16.6% (42/253) for level 7. For patients with tumours in the upper lobe, the median survival time was 32 months for those with MLNM in the subcarinal zone or lower zone compared with 83 months for those with MLNM only in the upper zone (P < 0.01). When the tumours were 1 cm or less, the incidence of MLNM to the lower zone for upper lobe tumours and of MLNM to the upper zone for lower lobe tumours was zero.
CONCLUSIONS
Different primary NSCLC lobe locations have a different propensity to be sites of MLNM for those tumours that are 3 cm or less. For tumours no larger than 1 cm, a lower zone mediastinal lymph node dissection might be unnecessary for upper lobe tumours and an upper zone mediastinal lymph node dissection might be unnecessary for lower lobe tumours.

Abstract
BACKGROUND Left mediastinal node dissection during lung cancer surgery can be difficult because paratracheal and subcarinal lymph nodes are concealed by mediastinal structures. Arterial ligament transection (ALT) offers a wide surgical view of concealed mediastinal spaces, thus enabling extended en bloc lymph node dissection (LND). We analyzed surgical outcomes of patients who underwent extended LND after ALT via video-assisted thoracoscopic surgery (VATS) for potentially node-positive clinical stage I non-small cell lung cancer (NSCLC). METHODS We retrospectively investigated the medical records of 75 patients who had undergone extended mediastinal node dissection after ALT via VATS for potentially node-positive NSCLC at our centers during the period from September 2008 through November 2015. Operative data and rates of overall survival (OS), in addition to mortality and morbidity, were analyzed in relation pathological stage and nodal stage. RESULTS Operative time was 238±58 minutes, and an average of 32.7±12.9 hilar and mediastinal lymph nodes were dissected. Lymph node metastases were detected in 34 patients (6 pN1 patients, 27 pN2 patients, and 1 pN3 patient). Mediastinal lymph node metastases were detected around the carina (stations 2L, 4L, and 7) in 19 of 27 patients with pN2 cancer. Nineteen patients had a total of 24 postoperative complications. Recurrent nerve paralysis was the most frequent complication (n=11) but resolved in eight patients during follow-up. Survival rates at 3 and 5 years were 92.2%/88.4%, 100.0%/60.0%, and 87.7%/81.0% for p-stage I, II, and III, respectively, and 92.2%/88.4%, 100.0%/60.0%, and 87.4%/80.7% for pN0, pN1, and pN2, respectively. CONCLUSIONS Extended mediastinal node dissection after ALT allowed detection of lymph node micrometastases in selected patients with potentially node-positive left NSCLC and may improve outcomes.

Abstract
Purpose To investigate the prognostic impact of 4L lymph node (LN) dissection in left lung cancer and to analyze the relative risk factors for 4L LN metastasis. Patients and Methods We retrospectively collected data from 657 patients with primary left lung cancer who underwent surgical pulmonary resection from January 2005 to December 2009. One hundred thirty-nine patients underwent 4L LN dissection (4LD+ group); the other 518 patients did not receive 4L LN dissection (4LD− group). Propensity score weighting was applied to reduce the effects of observed confounding between the two groups. Study end points were disease-free survival (DFS) and overall survival (OS). Results The metastasis rate of station 4L was 20.9%, which was significantly higher than those of station 7 (14.0%; P = .048) and station 9 (9.8%; P < .001). Station 4L metastasis was associated with most other LN station metastases in univariate analysis, but only station 10 LN metastasis was an independent risk factor for 4L LN metastasis (odds ratio, 0.253; 95% CI, 0.109 to 0.588; P = .001) in multivariate logistic analysis. The 4LD+ group had a significantly better survival than the 4LD− group (5-year DFS, 54.8% v 42.7%; P = .0376; 5-year OS, 58.9% v 47.2%; P = .0200). After allowing potential confounders in multivariate survival analysis, dissection of 4L LN retained its independent favorable effect on DFS (hazard ratio, 1.502; 95% CI, 1.159 to 1.947; P = .002) and OS (hazard ratio, 1.585; 95% CI, 1.222 to 2.057; P = .001). Propensity score weighting further confirmed that the 4LD+ group had a more favorable DFS ( P = .0014) and OS ( P < .001) than the 4LD− group. Conclusion Station 4L LN involvement is not rare in left lung cancer, and dissection of the 4L LN station seems to be associated with a more favorable prognosis as compared with those who did not undergo this dissection.

Abstract
Background The proper extent of lymph node dissection is still controversial. Hence, we compared the clinical efficacy between two strategies of lymph node dissection [selective lymph node dissection (SLND) and systematic lymph node dissection (LND)] for clinical N2-negative non-small cell lung cancer (NSCLC) patients. Methods After searching five databases, six cohort studies were eligible for this meta-analysis and the primary endpoint was overall survival (OS). In order to provide a comprehensive perspective, we estimated some perioperative outcomes as well. Either fixed effect or random effects model were properly selected to evaluate the data according to the heterogeneity of included studies. Results A total of 7,333 patients with clinical N2-negative NSCLC patients were analyzed for OS. The pooled results demonstrated that LND did not improve survival in OS [hazard ratio (HR) =1.05, 95% confidence interval (CI): 0.82-1.34, P=0.69] compared with SLND. In accordance with OS, there is no significant difference in DFS between LND and SLND (HR =0.98, 95% CI: 0.78-1.23, P=0.87). Moreover, SLND could significantly reduce the operative time [mean difference (MD) =-21.45, 95% CI: -29.53 to -13.36, P<0.001] and blood loss (MD =-28.88, 95% CI: -44.38 to -13.39, P<0.001). Both postoperative morbidity and recurrence showed no significant between two groups. Conclusions SLND is an alternative to LND for clinical N2-negative NSCLC patients, which may even provide clinical benefits. However, more randomized controlled trials (RCTs) are expected to determine whether SLND is valid and practical to become a standard procedure of surgical treatment for early-stage NSCLC patients.

Abstract
Lymph node dissection is a vital part of surgical treatment in early-stage non-small cell lung cancer (NSCLC). Removal of metastatic lymph nodes while preservation of intact lymph nodes are equally important. For hospitalized early-stage patients with limited lymph node metastasis, the operation treatment should be made according to some rules such as lobe-specific lymph node drainage pattern. In order to prevent unnecessary surgical trauma in early-stage patients, a minimally invasive approach with selective lymph node excision is preferred for more clinical benefits. This review summarizes the existing findings on lobe-specific lymph node drainage pattern and we hope to provide guidance for selective lymph node dissection (SLND). Furthermore, we include information on histologic views, a tumor marker and protocols of SLND, with hope to inspire creative research and clinical trials in this field.

Ann Thorac Surg 2017; 103:1121-1125. [PMID: 28109572 DOI: 10.1016/j.athoracsur.2016.09.109] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/17/2016] [Revised: 08/23/2016] [Accepted: 09/29/2016] [Indexed: 11/17/2022]
Abstract
BACKGROUND Mediastinal staging is of paramount importance for planning of treatment in non-small cell lung cancer (NSCLC). Single institution reports recently claimed that subcarinal lymph node dissection during resection of upper lobe NSCLC could be spared. We used a complete national lung cancer registry to investigate patterns of unsuspected mediastinal lymph node involvement after lobectomy. METHODS During an 11-year period (2004 to 2014) 5,577 consecutive patients who underwent operations for NSCLC were investigated for unsuspected mediastinal lymph node involvement (N2 disease) discovered at final histopathology. The analysis excluded patients with clinical N2 disease. We used a national registry to extract information for each patient about tumor location, histopathology, clinical and pathologic TNM stage, preoperative imaging modalities, and type of invasive mediastinal staging. RESULTS Mediastinal lymph node dissection was performed in 5,577 patients during the operation, and unsuspected N2 disease was discovered in 612 (11.0%), and 193 (3.5%) had subcarinal metastasis. Subcarinal N2 disease was significantly more common in patients with lower-lobe or middle-lobe cancers compared with upper-lobe cancers (5.8% vs 1.6%, p < 0.01). Preoperative invasive mediastinal staging was performed in 73.4% (4,097 of 5,577) of all patients and significantly more frequently in patients who eventually had N2 disease (87.3% [534 of 612], p < 0.01) as well subcarinal N2 disease (89.6% [173 of 193], p < 0.01). CONCLUSIONS Subcarinal lymph node metastases were common despite frequent use of preoperative invasive mediastinal staging in lower-lobe, middle-lobe, and upper-lobe NSCLC. Subcarinal lymph nodes should be dissected or sampled routinely during operations for NSCLC to avoid understaging-regardless of preoperative invasive mediastinal staging and tumor location.

Abstract
BACKGROUND Superior mediastinal and #11i lymph node (LN) metastases are adverse prognostic factors in patients with middle lobe lung cancer. We aimed to clarify the benefit of thorough lymphadenectomy by LN station or zone in middle lobe non-small-cell lung cancer (NSCLC). METHODS Among 295 patients who underwent pulmonary resection and thorough lymphadenectomy for primary right middle lobe (RML) NSCLC at two institutions, we enrolled 68 patients (33 men, 35 women) and retrospectively studied their data. We divided each N1 location (i.e., #10, #11s and #11i) into N1(-)N2(+) and N1(+)N2(+) and divided the #12m location into N1(+)N2(-), N1(-)N2(+) and N1(+)N2(+). RESULTS Interlobar node involvement was rare in pN1 NSCLC when compared with that in other N1 nodes. Lymph node dissection (LND) was beneficial when the hilar zone (HZ)/interlobar zone (IZ) LNs were located at the intermediate point of the upper zones (UZs) and subcarinal zones (SCZs), with the therapeutic benefit at the SCZ being 2.8-fold higher than that at the UZ and 9.7-fold higher than that at the lower zone (LZ). Furthermore, LND evidently had greater therapeutic value for the SCZ than the UZ, which was compatible with skip N2 metastases. CONCLUSIONS For middle lobe NSCLC, mediastinal LND should be considered a priority in the SCZ than in the UZ. Moreover, the HZ/IZ is central to unfavourable prognoses in patients with pN2 middle lobe NSCLC.

Abstract
BACKGROUND To evaluate the pattern of lymph node metastasis (LNM) according to primary tumor location in T1 and T2 stage non-small cell lung cancer (NSCLC) patients. METHODS The data of 1916 NSCLC patients with LNM who underwent surgery with systematic nodal resection between November 2008 to December 2014 were included in the study. Analyses of tumor location, pathological T stage, and nodal metastasis were performed. RESULTS In T1a stage patients, superior mediastinum, aortopulmonary, and inferior mediastinum lymph node metastases were observed in primary tumors present in the right upper lobe (RUL), left upper lobe (LUL) and right middle lobe (RML), respectively. In T1b-stage patients, superior mediastinum, aortopulmonary, and inferior mediastinum lymph node metastases were observed in the RML, LUL, and right lower lobe (RLL), respectively. In patients with T2a-stage, superior mediastinum, aortopulmonary and inferior mediastinum lymph node metastases were observed in the RUL, LUL, and RLL, respectively. However, in T2b-stage patients, RUL, LUL and RML locations were associated with superior mediastinum, aortopulmonary, and inferior mediastinum lymph node metastases, respectively. Multivariable logistic regression showed that T stage was significantly associated with mediastinal and intrapulmonary lymph node metastases. In addition, tumor location was significantly associated with N2 station LNM. CONCLUSION LNM varied according to tumor location and T-stage, which are independent factors influencing N2 station LNM.

Abstract
Background Left upper division segmentectomy is one of the major pulmonary procedures; however, it is sometimes difficult to completely dissect interlobar lymph nodes. We attempted to clarify the prognostic importance of hilar and mediastinal nodes, especially of interlobar lymph nodes, in patients with primary non-small cell lung cancer (NSCLC) located in the left upper division. Methods We retrospectively studied patients with primary left upper lobe NSCLC undergoing surgical pulmonary resection (at least lobectomy) with radical lymphadenectomy. The representative evaluation of therapeutic value from the lymph node dissection was determined using Sasako’s method. This analysis was calculated by multiplying the frequency of metastasis to the station and the 5-year survival rate of the patients with metastasis to the station. Results We enrolled 417 patients (237 men, 180 women). Tumors were located in the lingular lobe and at the upper division of left upper lobe in 69 and 348 patients, respectively. The pathological nodal statuses were pN0 in 263 patients, pN1 in 70 patients, and pN2 in 84 patients. Lymph nodes #11 and #7 were significantly correlated with differences in node involvement in patients with left upper lobe NSCLC. Among those with left upper division NSCLC, the 5-year overall survival in pN1 was 31.5% for #10, 39.3% for #11, and 50.4% for #12U. The involvement of node #11 was 1.89-fold higher in the anterior segment than that in the apicoposterior segment. The therapeutic index of estimated benefit from lymph node dissection for #11 was 3.38, #4L was 1.93, and the aortopulmonary window was 4.86 in primary left upper division NSCLC. Conclusions Interlobar node involvement is not rare in left upper division NSCLC, occurring in >20% cases. Furthermore, dissection of interlobar nodes was found to be beneficial in patients with left upper division NSCLC.

Abstract
According to the newest version of NCCN Clinical Practice Guidelines for Non-Small Cell Lung Cancer (NSCLC), increasing attentions are paid to the role of nodal status and other high-risk factors, including vascular invasion, wedge resection, tumors > 4 cm, visceral pleural involvement, and incomplete lymph node sampling in the individual clinical treatment. Precise definitions of T status and N status, closely associated with prognosis and treatment, are worth expanding further. However, complexity arises because no unity definition exists regarding individual T and N descriptors. In an attempt to explore the potential prognostic values of the T status and N status, we systematically review relevant literature and found that there still remained some disputes about the definitions and prognosis. The adjacent lobe invasion regarded as T2 or T3 has not been reached consensus yet so far. Lymph node spread patterns are associated with the treatment strategies of NSCLC. This review mainly focus on the role of T status and N status and tried to seek appropriate and individual treatment strategies in NSCLC.

Abstract
OBJECTIVES Understanding the clinicopathological features of patients with skip N2 metastases (SN2) in clinical early stage lung cancer is important for surgical planning and other treatment considerations; however, the factors associated with SN2 are unclear. This study aimed to investigate the clinicopathological features associated with SN2 in patients with clinical stage IA (cIA) non-small-cell lung cancer (NSCLC). METHODS We retrospectively studied patients with cIA NSCLC who underwent pulmonary resection (at least lobectomy) and extensive lymphadenectomy (more than ND2a-1) at our institution between January 2004 and December 2010. We investigated the following factors for their association with SN2: age; sex; tumour marker (carcinoembryonic antigen); tumour size on computed tomography (CT), evaluated with a lung-window (LW) and a mediastinal-window (MW) setting; pathology, with or without adenocarcinoma; differentiation; visceral pleural invasion (VPI) and vascular/lymphatic invasion. RESULTS In total, 422 patients were enrolled, with the following pathological node (pN) statuses: 331 pN0 (78.4%), 39 pN1 (9.3%) and 52 pN2 (12.3%). There were 21 (23.1%) SN2 cases among the patients with nodal metastases. When the cut-off level was defined as a receiver operating characteristic curve with MW (11.5 mm), the sensitivity and specificity of SN2 was 95.2% and 42.9%, respectively. VPI was a statistically independent relevant factor for SN2 in both the patients with cIA and in those with nodal involvement. The VPI classification comprised 59 PL-0 (64.8%), 12 PL-1 (13.2%) and 20 PL-2 (22.0%) with nodal metastases, and there was a significant difference between the three groups (P = 0.03) according to SN2 frequency. There was no difference between VPI 1 and 2 (P = 0.27). CONCLUSIONS In conclusion, our study suggests that the incidence of SN2 is significantly associated with VPI in patients with cIA NSCLC. Although MW (>11.5 mm) had a low specificity in the assessment of SN2, it had a high sensitivity, suggesting the possibility of a superior benefit compared with LW. Standard hilar and mediastinal lymph node dissection should be required in patients with suspicious VPI and MW (>11.5 mm) on preoperative CT.

Abstract
OBJECTIVES Nowadays, early-stage lung cancers are more frequently encountered. Selective lymph node (LN) dissection based on lobe-specific lymphatic pathway has been proposed. Our aim was to study nodal involvement according to tumour location. METHODS We reviewed 1779 lobectomized patients and analysed their pathological characteristics according to tumour location: Group 1 (G1), right upper lobe; Group 2 (G2), right middle lobe; Group 3 (G3), right lower lobe; Group 4 (G4), left upper division; Group 5 (G5), lingula; Group 6 (G6), left lower lobe. The pN status was recorded for each group to analyse the lymphatic spread of non-small-cell lung cancer (NSCLC) according to tumour location. RESULTS The numbers and proportions of lobectomies in each group were 613 patients in G1 (59.2%), 64 in G2 (6.4%), 359 in G3 (34.6%), 404 in G4 (54.3%), 54 in G5 (7.3%) and 286 in G6 (38.4%). The rates of pN2 involvement were similar, whatever the group was, even when deciphering single- and multistation diseases. on the right side, single-station N2 disease was mainly found in the superior mediastinum (SM) for G1 (95%), and in the inferior for G3 (90%). On the left side, single-station N2 was mainly found in the SM in G4 (94%), and the inferior in G6 (48%). Whatever the side, in case of two-station involvement, both mediastina were concerned in 40% (in G4) to 81% of the case (in G3). Long-term survival rates were different in skip metastasis, single- and multistation involvement, but not between lobes. CONCLUSIONS Tumour location is not a predictor of nodal metastasis pattern. In surgical treatment of NSCLC, complete systematic mediastinal LN dissection remains the only acceptable procedure from an oncological point of view.
