Predictive value of pre-operative prognostic nutritional index and systemic immune-inflammation index for efficacy and survival in patients with non-small cell lung cancer undergoing neoadjuvant chemotherapy. Am J Transl Res 2024; 16:2024-2033. [PMID: 38883356 PMCID: PMC11170607 DOI: 10.62347/rrvr5429] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2024] [Accepted: 04/29/2024] [Indexed: 06/18/2024]
Abstract
OBJECTIVE To explore the predictive value of preoperative prognostic nutritional index (PNI) and systemic immune inflammation index (SII) in relation to the efficacy and prognosis in patients with non-small cell lung cancer (NSCLC) undergoing neoadjuvant chemotherapy (NACT). METHODS Data of patients with stage IIIA-N2 NSCLC who received NACT in the 910th Hospital of Chinese People's Liberation Army from January 2017 to April 2020 were retrospectively analysed. Patients undergoing NACT were divided into the pCR group (80 cases with complete remission or partial remission) and the non-pCR group (46 cases with stable disease or progressive disease) in accordance with their treatment outcome. The pathologic and clinical data of the patients were collected and analysed to identify the factors affecting efficacy of NACT for stage IIIa-N2 NSCLC, and to evaluate the predictive value of PNI and SII in determining the efficacy of NACT. The patients were followed up for 3 years to observe the overall survival, and Cox regression analysis was employed to identify the risk factors affecting patient survival. Furthermore, the effect of PNI and SII on the survival time was analysed. RESULTS Multivariate regression analysis showed that tumor diameter, PNI, and SII were influencing factors for poor efficacy of NACT in patients with stage IIIa-N2 NSCLC. The non-pCR group exhibited a higher mortality within 3 years, thus a lower 3-year overall survival rate than the pCR group (P<0.05). Cox regression analysis revealed that both PNI and SII were risk factors for poor prognosis in patients with stage IIIa-N2 NSCLC undergoing NACT. Further analysis found a lower 3-year survival rate in patients with low PNI and high SII than in counterparts (P<0.05). CONCLUSION Tumor diameter, PNI and SII are risk factors for poor efficacy in patients with stage IIIa-N2 NSCLC undergoing NACT. Low PNI and high SII can indicate a poor prognosis in these patients.

Abstract
Systematic lymph node dissection has been widely accepted and turned into a standard procedure for lung cancer surgery. In recent years, the concept of "minimal invasive surgery (MIS)" has greatly changed the surgical paradigm of lung cancer. Previous studies revealed that excessive dissection of lymph nodes without metastases had uncertain clinical benefit. Meanwhile, it leads to the elevated risk of postoperative complications including chylothorax and laryngeal nerve injury. In addition, dissection of nonmetastatic lymph nodes may disturb systematic immunity, resulting in the secondary effect on primary tumor or latent metastases. The past decades have witnessed the innovative strategies such as lobe-specific lymph node dissection and selective lymph node dissection. On the basis of evolution of lymph node dissection strategy, we discuss the negative effects of excessive nonmetastatic lymph node dissection and summarize the recent advances in the optimized dissection strategies, hoping to provide unique perspectives on the future directions.

Abstract
OBJECTIVES Selective mediastinal lymph node dissection based on lobe-specific metastases is widely recognized in daily practice. However, the significance of mediastinal lymph node dissection for N1-positive tumors has not been elucidated. METHODS We retrospectively reviewed 359 patients with N1-positive lung cancer who underwent lobectomy with systematic mediastinal lymph node dissection (systematic lymph node dissection) (n = 150) and lobe-specific mediastinal lymph node dissection (lobe-specific lymph node dissection) (n = 209). The operative and postoperative results and their propensity score-matched pairs were compared. The factors affecting survival were assessed using competing risk and multivariable analyses. RESULTS The cumulative incidence of recurrence and the cumulative incidence of cancer-specific death were not significantly different between systematic and lobe-specific lymph node dissection in entire cohort. In the propensity score-matched cohort (83 pairs), systematic lymph node dissection tended to detect N2 lymph node metastasis more frequently (55.4 vs. 41%, P = 0.087). Eleven patients (13.2%) in the systematic lymph node dissection group had a metastatic N2 lymph node 'in the systematic lymph node dissection field' that lobe-specific lymph node dissection did not dissect. The oncological outcomes between patients undergoing systematic lymph node dissection (5-year cumulative incidence of recurrence, 62.1%; 5-year cumulative incidence of cancer-specific death, 27.9%) and lobe-specific lymph node dissection (5-year cumulative incidence of recurrence, 60.1%; 5-year cumulative incidence of cancer-specific death, 23.3%) were similar. The propensity score-adjusted multivariable analysis for cumulative incidence of recurrence revealed that the prognosis associated with systematic lymph node dissection was comparable with the prognosis with lobe-specific lymph node dissection (hazard ratio, 1.17; 95% confidence interval, 0.82-1.67; P = 0.37). CONCLUSIONS The extent of lymph node dissection can affect accurate pathological staging; however, it was not associated with survival outcome in the treatment of N1-positive lung cancer.

Abstract
Lung cancer remains the leading cause of cancer-related death worldwide. The involvement of lymph nodes by the tumor has a strong impact on survival of patients. For this reason, lymphadenectomy plays a crucial role in the staging and prognosis of NSCLC, to define the most appropriate therapeutic strategies concerning the stage of the disease. To date, the benefit, in terms of survival, of the different extents of lymphadenectomy remains controversial in the scientific community. It is recognized that metastatic involvement of mediastinal lymph nodes in lung cancer is one of the most significant prognostic factors, in terms of survival, and it is therefore mandatory to identify patients with lymph node metastases who may benefit from adjuvant therapies, to prevent distant disease and local recurrences. The purpose of this review is to evaluate the role of lymphadenectomy in early-stage NSCLC in terms of efficacy and accuracy, comparing systematic, sampling, and lobe-specific lymph node dissection and analyzing the existing critical issue, through a search of the most relevant articles published in the last decades.

Removing different number of regional lymph nodes affects survival outcomes of operable patients at stage IIA non-small cell lung cancer (according to the 8th edition staging). J Thorac Dis 2023; 15:552-567. [PMID: 36910092 PMCID: PMC9992567 DOI: 10.21037/jtd-22-1314] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Accepted: 01/13/2023] [Indexed: 02/04/2023]
Abstract
Background Surgery combined with chemotherapy (CT) is the best treatment for tumor patients at stage I to IIIA. But there are only few studies specifically evaluated the survival benefits of removing different number of regional lymph nodes (RLNs) for patients with stage IIA non-small cell lung cancer (NSCLC). The objective of this study is to discuss the effect of removing different number of RLNs on survival outcomes in operable patients at stage IIA NSCLC. Methods Through the use of the Surveillance, Epidemiology, and End Results (SEER) registry, satisfactory patients at stage IIA NSCLC, who had complete clinical information from 2004 to 2015, were identified. Lung cancer-specific survival (LCSS) and overall survival (OS) were compared by the Kaplan-Meier analysis and Cox regression analyses to determine the impact of the confounding factors on the survival outcomes. LCSS and OS as the primary endpoints were compared among patients with different number of RLNs removed. Results A total of 3,362 patients at stage IIA NSCLC met our criteria, including 173 (5.1%), 486 (14.5%), 2,703 (80.4%) patients without RLNs removed, with 1 to 3 RLNs removed and with greater than or equal to 4 RLNs removed, respectively. Kaplan-Meier survival analyses and Univariate Cox regression analyses revealed that there was a statistically significant difference on survival curve (log rank P<0.001) among the stage IIA NSCLC patients with different number of RLNs removed. Furthermore, multivariable Cox regression analyses on LCSS showed that the hazard ratio (HR) and 95% confidence interval (95% CI) of the 1 to 3 RLNs removed group and greater than or equal to 4 RLNs removed group were 0.622 (0.484-0.800, P<0.001) and 0.545 (0.437-0.680, P<0.001), respectively, compared to without any RLNs removed group. Conclusions This study illustrated that removing different number of RLNs can affect survival outcomes of operable patients at stage IIA NSCLC. Whether more radical lymphadenectomy is beneficial to patients at stage IIA NSCLC still needs to be researched.

Abstract
BACKGROUND To date, no clinical trials on the use of induction therapy before surgery have focused solely on lung squamous cell carcinoma (LSCC). We report the results of the Personalized Induction Therapy-2 (PIT-2) trial, a multicenter phase II study, performed to investigate the efficacy and safety of S-1 + cisplatin with concurrent thoracic radiotherapy (TRT) followed by surgery in patients with stage IIIA (N2) LSCC. METHODS Patients with pathologically proven stage IIIA (N2) LSCC received induction therapy comprising three cycles of S-1 + cisplatin with concurrent TRT (45 Gy in 25 fractions) followed by surgery. S-1 was administered orally at a dose of 40 mg/m2 twice daily on days 1-14, in addition to intravenous infusion of cisplatin (60 mg/m2) on day 1. The primary endpoint was 2-year progression-free survival (PFS) rate. RESULTS Of 45 registered patients, 43 underwent induction therapy. Of the 43 patients, 39 (91%) underwent surgery (35 lobectomies, 3 pneumonectomies, and 1 wedge resection). The 2-year PFS, 2-year overall survival, objective response rate, and pathological complete response rates were 67% (90% confidence interval [CI] 54-78%), 70% (95% CI 53-81%), 86% (95% CI 76-96%), and 39% (95% CI 23-54%), respectively. No new treatment-related adverse events occurred during the induction therapy. One case of 90-day postoperative mortality involving a patient who underwent right pneumonectomy and developed pneumonia after discharge occurred. CONCLUSIONS Induction therapy using S-1 + cisplatin with concurrent TRT followed by surgery is a feasible and promising treatment approach for stage IIIA (N2) LSCC.

Abstract
Introduction As the long-term prognosis of esophageal cancer (EC) is improving, concerns of a second primary malignancy (SPM) have increased. However, research on lung cancer as the SPM after EC is limited. Therefore, we aimed to explore the prognostic factors and clinical treatment decisions of patients with second primary lung cancer following esophageal cancer (SPLC-EC). Materials and methods We identified the data of 715 patients with SPLC-EC from the Surveillance, Epidemiology, and End Results (SEER) database during 1975 to 2016. We established a nomogram through Cox regression modelling to predict the prognosis of patients with SPLC-EC. We determined the association between factors and cancer-specific mortality using the Fine-Gray competing risk model. Then, we performed survival analysis to evaluate the benefits of different treatment methods for overall survival (OS). Results The multivariate analysis indicated that sex, insurance recode, age, surgery and chemotherapy 0for first primary malignancy (FPM), primary site, stage, and surgery for SPM were independent prognostic factors for OS. Using concordance indices for OS, the nomogram of our cohort showed a higher value than the SEER historic-stage nomogram (0.8805 versus 0.7370). The Fine-Gray competing risk model indicated that surgery for FPM and SPM was the independent prognostic factor for EC-specific mortality (P=0.016, hazard ratio [HR] = 0.532) and LC-specific mortality (p=0.016, HR=0.457), respectively (p<0.001). Compared to the patient group having distant metastasis, patients with localized and regional metastasis benefitted from undergoing surgery for SPM (P<0.001, P<0.001, respectively). For patients without surgery for SPM, radiotherapy (P<0.001) and chemotherapy (P<0.001) could improve OS. Conclusions Surgery remains the mainstay for managing SPLC-EC, especially for localized and regional tumors. However, chemotherapy and radiotherapy are recommended for patients who cannot undergo surgery. These findings can have implications in the treatment decision-making for patients with SPLC-EC.

One-step nucleic acid amplification for intraoperative diagnosis of lymph node metastasis in lung cancer patients: a single-center prospective study. Sci Rep 2022; 12:7297. [PMID: 35508484 PMCID: PMC9068616 DOI: 10.1038/s41598-022-11064-4] [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: 02/21/2022] [Accepted: 04/01/2022] [Indexed: 11/24/2022] Open
Abstract
One-step nucleic acid amplification (OSNA) is a rapid intraoperative molecular detection technique for sentinel node assessment via the quantitative measurement of target cytokeratin 19 (CK19) mRNA to determine the presence of metastasis. It has been validated in breast cancer but its application in lung cancer has not been adequately investigated. 214 LNs from 105 patients with 100 primary lung cancers, 2 occult primary lung tumors, and 3 metastatic lung tumors, who underwent surgical lung resection with LN dissection between February 2018 and January 2020, were assessed. Resected LNs were divided into two parts: one was snap-frozen for OSNA and the other underwent rapidly frozen histological examination. Intraoperatively collected LNs were evaluated by OSNA using loop-mediated isothermal amplification and compared with intraoperative pathological diagnosis as a control. Among 214 LNs, 14 were detected as positive by OSNA, and 11 were positive by both OSNA and intraoperative pathological diagnosis. The sensitivity and specificity of OSNA was 84.6% and 98.5%, respectively. The results of 5 of 214 LNs were discordant, and the remainder all matched (11 positive and 198 negative) with a concordance rate of 97.7%. Although the analysis of public mRNA expression data from cBioPortal showed that CK19 expression varies greatly depending on the cancer type and histological subtype, the results of the five cases, except for primary lung cancer, were consistent. OSNA provides sufficient diagnostic accuracy and speed and can be applied to the intraoperative diagnosis of LN metastasis for non-small cell lung cancer.

Abstract
PURPOSE To investigate the surgical prognosis and efficacy of adjuvant therapy in non-small cell lung cancer (NSCLC) with occult lymph node metastasis (ONM) defined by positron emission tomography/computed tomography (PET/CT). METHODS A total of 3537 NSCLC patients receiving surgical resection were included in this study. The prognosis between patients with ONM and evident nodal metastasis, ONM patients with and without adjuvant therapy was compared, respectively. RESULTS ONM was associated with significantly better prognosis than evident nodal metastasis whether for patients with N1 (5-year OS: 56.8% versus 52.3%, adjusted p value = 0.267; 5-year RFS: 44.7% versus 33.2%, adjusted p value = 0.031) or N2 metastasis (5-year OS: 42.8% versus 32.3%, adjusted p value = 0.010; 5-year RFS: 31.3% versus 21.6%, adjusted p value = 0.025). In ONM population, patients receiving adjuvant therapy yielded better prognosis comparing to those without adjuvant therapy (5-year OS: 50.1% versus 33.5%, adjusted p value < 0.001; 5-year RFS: 38.4% versus 22.1%, adjusted p value < 0.001). CONCLUSIONS ONM defined by PET/CT identifies a unique clinical subtype of lung cancer, ONM is a favorable prognostic factor whether for pathological N1 or N2 NSCLC and adjuvant therapy could provide additional survival benefits for ONM patients.

Abstract
BACKGROUND Outcomes after segmentectomy compare favorably with those after lobectomy in patients with stage I non-small cell lung cancer (NSCLC). Whether long-term outcomes vary by segmentectomy location is unclear. We investigated whether disease-free survival (DFS) and overall survival (OS) differ by segmentectomy location after intentional segmentectomy for clinical T1 N0 M0 NSCLC. METHODS Patients who received intentional segmentectomy for cT1 N0 M0 NSCLC from 2000 to 2018 were reviewed. Patients with prior lung cancer, forced expiratory volume in 1 second of less than 50%, or R1/R2 resection were excluded. Segmentectomy groups were left (L) basilar, L segment 6, L lingula, L trisegment; right (R): basilar (R_Bas), segment 6 (R_S6), and R upper. The 5- and 10-year DFS and OS were estimated using Kaplan-Meier and compared between groups using the log-rank test. Factors associated with DFS and OS were determined using Cox proportional hazards models. RESULTS In total, 416 patients met the inclusion criteria. Segmentectomy groups differed with regard to surgical approach, mediastinal lymphadenectomy, lymphovascular invasion, tumor histology, margin distance, and adjuvant therapy. Long-term outcomes were worst after R_S6 resection (5-year DFS, 57.6% [95% confidence interval {CI}, 45.7%-72.7%]; OS, 66.3% [95% CI, 54.7%-80.3%]) and best after R_Bas resection (5-year DFS, 77.1% [95% CI, 59.2%-100%]; OS, 79.5% [95% CI, 60.9%-100%]). On multivariable analysis, R_S6 resection was independently associated with DFS vs R_Bas (hazard ratio, 2.89; 95% CI, 1.18-7.08; P = .02) and OS vs R_Bas (hazard ratio, 4.35; 95% CI, 1.61-11.76; P = .004). CONCLUSIONS Resection of R_S6 is independently associated with worse DFS and OS in patients receiving intentional segmentectomy for cT1 N0 M0 NSCLC and may warrant more extensive resection, complete lymph node dissection, and closer postoperative surveillance.

Lymph Node and Bone Marrow Micrometastases Define the Prognosis of Patients with pN0 Esophageal Cancer. Cancers (Basel) 2020; 12:cancers12030588. [PMID: 32143307 PMCID: PMC7139797 DOI: 10.3390/cancers12030588] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2020] [Revised: 02/27/2020] [Accepted: 03/02/2020] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Pathological routine lymph node staging is postulated to be the main oncological prognosticator in esophageal cancer (EC). However, micrometastases in lymph nodes (LNMM) and bone marrow (BNMM) are discussed as the key events in tumor recurrence. We assessed the prognostic significance of the LNMM/BNMM status in initially pN0 staged patients with curative esophagectomy. METHODS From 110 patients bone marrow aspirates and lymph node tissues were analyzed. For LNMM detection immunohistochemistry was performed using the anticytokeratin antibody AE1/AE3. To detect micrometastases in the bone marrow a staining with the pan-keratin antibody A45-B/B3 was done. Results were correlated with clinicopathologic parameters as well as recurrence and death during follow-up time. RESULTS Thirty-eight (34.5%) patients showed LNMM, whereas in 54 (49.1%) patients BNMM could be detected. LNMM and BNMM positive patients showed a correlation to an increased pT category (p = 0.017). Univariate and multivariate analyses revealed that the LNMM/BNMM status and especially LNMM skipping the anatomical lymph node chain were significant independent predictors of overall survival and recurrence-free survival. CONCLUSIONS This study indicates that routine pathological staging of EC is insufficient. Micrometastases in lymph nodes and the bone marrow seem to be the main reason for tumor recurrence and they are a strong prognosticator following curative treatment of pN0 EC.

Abstract
Background To determine the impact of the number of harvested mediastinal lymph nodes (MLNs) and assessed N2 stations on the mediastinal recurrence for pathologic stage I invasive lung adenocarcinoma (IADC). Methods A total of 2,048 patients with stage I IADC undergoing surgical resection were enrolled at Shanghai Chest Hospital from 2009 to 2013. Survival analysis was performed by Kaplan-Meier method along with univariable and multivariable cox regression analysis. Results For patients with ≥5 MLNs, mediastinum-specific relapse-free survival (MS-RFS) rates were 98.3% and 96.6% for 3- and 5-year, respectively, which significantly demonstrated better survival outcomes against those with <5 MLNs (96.3% and 92.8%, respectively, log-rank P=0.018). Additionally, the 3- and 5-year RFS of patients with assessed N2 stations ≥3 (98.2% and 95.8%) were exceptionally better when compared with those with N2 stations <3 (95.5%, 90.3%, log-rank P<0.001). In the univariable and multivariable cox analyses, we found that the number of assessed N2 stations was an independent predictor to MS-RFS (HR =0.468; 95% CI, 0.312-0.867; P=0.020) as opposed to the number of harvested MLNs (HR =0.856; 95% CI, 0.423-1.489; P=0.543) which was not a predictor. Conclusions Based on our results, we recommend, for a better MS-RFS among patients with pathological stage I IADC, that the cutoff values for harvested MLNs and assessed N2 stations be 5 and 3, respectively. In addition, the number of assessed N2 stations was still an independent predictor to MS-RFS.

Abstract
BACKGROUND The management of N2 non-small cell lung cancer (NSCLC) found at operation is controversial. Current guidelines recommend adjuvant chemotherapy or adjuvant chemoradiotherapy. We evaluated whether adjuvant chemoradiotherapy was associated with improved survival compared with adjuvant chemotherapy in patients with N2 NSCLC after complete resection. METHODS We queried the National Cancer Database for all patients with clinical N0, pathologic N2 NSCLC who did not receive preoperative therapy and underwent complete (R0) surgical resection, followed by adjuvant chemotherapy or chemoradiotherapy. We performed propensity matching to create a well-balanced cohort of patients with respect to age, sex, race, comorbidities, treating facility, tumor size, year of diagnosis, and number of positive nodes. Survival was examined using the Kaplan-Meier method with log-rank analysis. RESULTS We identified 2,031 eligible patients; 1,149 (56.6%) received adjuvant chemotherapy and 882 (43.4%) received chemoradiotherapy. Patients in the unmatched cohort who received chemoradiotherapy tended to be younger (64.2 vs 65.4 years) and to have a comorbidity score of 0 (57.5% vs 52.1%). Median survival was similar (3.9 years with chemoradiotherapy vs 3.8 years with adjuvant chemotherapy, p = 0.518). We then identified 848 well-matched pairs and again did not detect differences in median survival (3.9 years with chemoradiotherapy vs 3.8 years with adjuvant chemotherapy, p = 0.705). CONCLUSIONS In a large database study, the addition of radiotherapy to adjuvant chemotherapy after resection of N2 NSCLC was not associated with improved survival. Until more definitive data are available, consideration should be given to treating patients with N2 disease detected at resection with adjuvant chemotherapy only.

Abstract
Background Lymph node metastasis is critical for the prognosis of non-small cell lung cancer (NSCLC) patients, and understanding of the pattern of lymph node metastasis is key to the treatment. We aim to investigate the N2 NSCLC patients without N1 lymph node involvement. Methods From 1999 to 2005, a total of 803 patients with pN2 NSCLC were enrolled in this study. Among them, 137 pN2 patients with no metastasis at the hilar (N1) lymph nodes [skip (+) group] were compared with the other 666 patients [skip (-) group]. Results The percentage of male, smoker and squamous cell carcinoma patients were significantly higher in the skip (+) group, (83.21% vs. 64.11%, P<0.001; 76.64% vs. 53.60%, P<0.001; 50.36% vs. 37.54%, P=0.007, respectively). Also, the primary tumor of skip (+) group patients were significantly more often located in the right upper and middle lobe (43.07% vs. 23.42%, 10.95% vs. 4.05%, P=0.001), and metastasis more frequently involved one lymph node station (75.18% vs. 49.55%, P<0.001). There was no significant difference in the number of total and N2 lymph node dissected. The postoperative survival of patients in both groups were also similar (P=0.379). Conclusions Skipping mediastinal lymph node metastasis happens in about 17% of NSCLC patients with mediastinal lymph nodes metastasis but it is not a prognostic factor.

Abstract
Objectives Early clinical stage (T1 and T2) non-small cell lung cancer (NSCLC) is commonly treated with anatomic lung resection and lymph node sampling or dissection. The aims of this study were to evaluate the incidence and the distribution of occult N2 disease according to tumour location and the short- and long-term outcomes. Methods We performed a retrospective review of patients with clinical stage I NSCLC who underwent anatomic lung resection and lymphadenectomy. Mediastinal lymphadenectomy (ML) was defined as resection of at least 2 mediastinal stations, always including station 7 lymph nodes. Patients who had a lobe-specific lymphadenectomy were excluded. Results One thousand six hundred and sixty-seven consecutive patients met inclusion criteria and were included. Overall, 9% (146/1667) of the patients had occult pN2 disease. At multivariable analysis, adenocarcinoma histology and vascular invasion were independently associated with greater risk of occult pN2 disease. In left and right upper lobe tumours, station 7 nodes were involved in 5 and 13% of pN2 positive cases, respectively. Station 5 and station 2/4 nodes were involved in 29 and 18% of left and right lower lobe pN2 tumours, respectively. There was no postoperative mortality, and postoperative morbidity was 28%. The median overall survival was 77.4 months. N0 patients had a median overall survival of 83.7 months vs 48.0 months and 37.9 months in N1 and N2 populations, respectively ( P < 0.001). Conclusions Sixteen percent of pN2 patients had mediastinal lymph node metastasis beyond the lobe-specific lymphatic drainage. We recommend a complete lymphadenectomy be performed, even in clinical stage I NSCLC.

Abstract
The greater the number of lymph node (LN) sampled (NLNsS) during lung cancer surgery, the lower the risk of underestimating the pN-status and the better the outcome of the pN0-patients due to stage-migration. Thus, regarding LN sampling "to be or not to be", number is the question. Recent studies advocate removing 10 LNs. The most suitable NLNsS is unfortunately impossible to establish by mathematics. A too high NLNsS variability exists, based on anatomy, surgery and pathology. The methodology may vary according to Inter-institutional differences in the surgical approach regarding LN inspection and number sampling. The NLNsS increases with the type of resection: sublobar, lobectomy or pneumonectomy. Concerning pathology, one LN may be divided into several pieces, leading to number overestimation. The pathological examination is limited by the number of slices analyzed by LN. The examined LNs can arbitrarily depend on the probability of detecting nodal metastasis. In fact, the only way to ensure the best NLNsS and the best pN-staging is to remove all LNs from the ipsilateral mediastinal and hilar LN-stations as they are discovered by thoroughly dissecting their anatomical locations. In doing so, a deliberate lack of harvest of LNs is unlikely, number turns out not to be the question anymore and a low NLNsS no longer means incomplete surgery. This prevents from judging as incomplete a complete LN dissection in a patient with a small NLNsS and from considering as complete a true incomplete one in a patient with a great NLNsS. Precise information describing the course of the operation and furnished in the surgeon's reports is also advisable to further improve the quality of LN-dissection, which ultimately might be beneficial in the long-term to patients. However, that procedure is of limited interest in pN-staging if LNs are not thoroughly examined and also described by the pathologist.

Abstract
Objective The use of postoperative radiotherapy (PORT) remains controversial for Stage IIIA-N2 non-small-cell lung cancer (NSCLC) patients, a possible reason is that IIIA-pN2 NSCLC diseases are a heterogeneous group with different clinicopathologic features. The aim of this research was to prove whether the mediastinal lymph nodes’ (LNs) skipping status could indicate the necessity of the PORT for the pN2 NSCLC patients. Methods The skip metastasis was defined as pN0N2 (no N1 LN involved), and nonskip metastasis was pN1N2 (one or more N1 LNs involved). Patients were divided into two groups: LNs nonskip and LNs skip, and postoperative chemoradiotherapy (POCRT) and postoperative chemotherapy. Then, the LN nonskip and LN skip groups were further divided into subgroups: POCRT and point of care testing (POCT) for subgroup analysis. Results There were 220 cases included in the analysis, and 43 of them received PORT. On univariate analysis, the median 3-year progression-free survival (PFS) was, respectively, 16 months (27.7%) for the LN skip group and 11 months (15.3%) for the LN nonskip group (P=0.001). The median 3-year overall survival (OS) was, respectively, 35 months (47.0%) for the LN skip group and 27 months (38.7%) for the LN nonskip group (P=0.025). The median 3-year local recurrence-free survival (LRFS) was, respectively, 25 months (41.0%) for the LN skip group and19 months (29.9%) for the LN nonskip group (P=0.014). The median 3-year distant metastasis-free survival (DMFS) was, respectively, 22 months (32.5%) for the LN skip group and 15 months (20.4%) for the LN nonskip group (P=0.013). The median 3-year PFS was, respectively, 17 months (25.6%) for the POCRT group and 12 months (18.6%) for the POCT group (P=0.037). Although the POCRT group showed better OS, LRFS, and DMFS than the POCT group, the results showed no statistical significance. In subgroup analysis, there was no statistical significance in the Kaplan–Meier analysis between subgroups, but it showed that POCRT resulted in better PFS, OS, and DMFS in both LN skip and LN nonskip subgroups; this advantage was more obvious in the LN skip subgroup. Conclusion The LN skip status is closely related to the survival of the IIIA-N2 NSCLC disease, and the LN skip patients may get more benefit in PFS and LRFS than the LN nonskip patients from PORT.

Abstract
目前,肺癌已是全球范围内发病率及死亡率最高的恶性肿瘤,非小细胞肺癌(non-small cell lung cancer, NSCLC)约占肺癌80%。手术治疗在早期NSCLC治疗中占主导地位,而淋巴结分期及手术中清扫程度直接影响着患者术后生活质量及患者的预后。解剖性肺叶切除加系统性淋巴结清扫一直以来被认为是NSCLC的标准手术方式,但对早期NSCLC患者纵隔淋巴结清扫程度问题上一直存在较大争议,精确评估区域淋巴结的转移及淋巴结清扫的程度是影响患者围手术期并发症和预后的重要因素。对于早期肺癌行肺叶特异性或选择性淋巴结清扫已逐渐为国内外学者接受,并可能成为临床Ⅰ期NSCLC患者标准淋巴结清扫方式。

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.

Abstract
BACKGROUND It has been proposed that examining a greater number of lymph nodes (LNs) in patients with non-small-cell lung cancer (NSCLC) treated by surgical resection may increase the likelihood of proper staging and affect outcome. Our purpose was to evaluate the interindividual variability and prognostic relevance of the number of LNs harvested during complete pulmonary and mediastinal lymphadenectomy performed for NSCLC. METHODS We prospectively collected and retrospectively reviewed the data from 1,095 patients who underwent lung cancer resection in association with systematic lymphadenectomy and pulmonary and mediastinal LN counts from 2004 to 2009. We analyzed the interindividual variability and prognostic impact of the number of LNs on overall survival (OS). RESULTS The mean number of harvested pulmonary and mediastinal LNs was 17.4±7.3 (range, 1-65) and was higher in male patients, right lung surgical procedures, lobectomy and pneumonectomy, N2 disease, and pIII stage. The mean number of harvested mediastinal LNs was 10.7±5.6 and was normally distributed (range, 0-49; median, 10). The 5-year survival rate was 53.8%. Overall survival was influenced by the number of involved stations (single-station versus multi-station disease, 5-year survival rates 31.5% versus 16.9%, respectively; p=0.041) but not by the number of harvested LNs, the number of harvested mediastinal LNs, or the number of positive mediastinal LNs. CONCLUSIONS After lung cancer resection and complete lymphadenectomy, the number of LNs is subject to normally distributed interindividual variability, with no significant impact on OS. Recommending an optimal number of nodes is therefore arbitrary. Instead, our recommendation is to perform a complete systematic pulmonary and mediastinal lymphadenectomy following established anatomical boundaries.

Abstract
BACKGROUND N2 involvement has dramatic consequences on the prognosis and management of patients with non-small cell lung cancer (NSCLC). N2-NSCLC may present with or without N1 involvement, constituting non-skip (pN1N2) and skip (pN0N2) diseases, respectively. As the prognostic impact of this subclassification is still a matter of debate, we analyzed the prognosis of pN2 patients according to the pN1-involvement and the number of N2-stations concerned. METHODS The medical records of consecutive patients who underwent surgery for pN2-NSCLC in 2 French centers between 1980 and 2009 were prospectively collected and retrospectively reviewed. Patients undergoing induction therapy, exploratory thoracotomy, incomplete mediastinal lymphadenectomy, or incomplete resections were excluded. The prognoses of pN1N2 and pN0N2 patients were first compared, and then deciphered according to the number of N2 stations involved (single-station: 1S, multi-station: 2S). RESULTS All together, 871 patients underwent first-line complete surgical resection for pN2-NSCLC during the study period, including 258 pN0N2 (29.6%) and 613 pN1N2 (70.4%) patients. Mean follow-up was 72.8±48 months. Median, 5- and 10-year survivals were, respectively, 30 months, 34%, and 24% for pN0N2 and 20 months, 21%, and 14% for pN1N2 patients (p<0.001). Multivariate analysis revealed 3 different prognostic groups; ie, favorable in pN0N2-1S disease, intermediate in pN0N2-2S and pN1N2-1S diseases, and poor in pN1N2-2S disease (p<0.001). CONCLUSIONS Among pN2 patients, the combination of N1 involvement (pN0N2 vs pN1N2) and number of involved N2 stations (1S vs 2S) are independent prognostic factors. These results might be taken into consideration to sub-classify the heterogeneous pN2-NSCLC group of patients.

Abstract
BACKGROUND Treatment for patients with N2-positive stage IIIA non-small cell lung cancer has been a controversial issue. The current study evaluated the outcomes in patients treated with trimodality therapy, which consisted of neoadjuvant radiation therapy concurrent with chemotherapy followed by surgical resection, with emphasis on clinical and pathologic nodal status. METHODS We reviewed the records of 355 patients who were treated with trimodality therapy between 1997 and 2011. RESULTS After completion of neoadjuvant chemoradiation, overall down-staging and complete response rates were 50.4 % (179 patients), and 13.2 % (47 patients), respectively. With median follow-up of 35.3 months, median times of progression-free survival (PFS) and overall survival (OS) were 16.3 months and 45.5 months, respectively. Seventeen patients (4.8 %) died of postoperative complications, and the remaining 338 patients were analyzed on prognostic factors. Old age (p = 0.032), pneumonectomy (p < 0.001), and ypN+ (p < 0.001) were found to be the significant prognosticators for worse PFS, and old age (p = 0.013), pneumonectomy (p < 0.001), and ypN+ (p < 0.001) were related to worse OS. Clinical N2 status did not influence either OS or PFS: the number of involved stations (single station vs. multi-station; p = 0.187 for PFS; p = 0.492 for OS), and bulk (clinically evident vs. microscopic; p = 0.902 for PFS; p = 0.915 for OS). CONCLUSION ypN stage was the most important prognosticator for both PFS and OS; however, neither initial bulk nor extent of cN2 disease influenced prognosis. Surgery following neoadjuvant chemoradiation should have contributed to improved clinical outcomes regardless of clinical nodal bulk and extent.

Abstract
Lung cancer is characterized by its lymphophilia. Its metastatic spread mainly occurs by tumor cells lymphatic drainage into the blood circulation. Initially, the lymph node TNM classification was based on clinical and therapeutic considerations, particularly concerning N2 involvement. The goals were to avoid futile exploratory thoracotomies without lung resection, to provide more accurate data from mediastinoscopy, and to take into account the radiation therapy fields. Since 1997, the international lymph node classification was more used to analyse the disparities within N1 and N2 groups. However, this attempt did not succeed in clarifying the lymphatic metastazing process, and was not progressing any more. Anatomy not being considered, it did not permit to grasp the anatomical and physiological significances of N2 and N3 involvement. In effect, this classification is now confined in zones and is lacking the anatomical and physiological descriptions that characterise the lymphatic pathways draining the lungs and their tumoral pathology. The stations proposed in numbers in cartographies should have gained in accuracy and in prognostic value if they had been expressed in their anatomical counterparts.

Abstract
BACKGROUND Historically, right middle lobe (RML) non-small cell lung cancer (NSCLC) has been reported to be associated with a higher rate of pneumonectomy than other right-sided locations. Because this would discourage minimally invasive approaches in RML-NSCLC, we sought to update this assertion through the study of a large surgical series. METHODS Clinical records of patients who underwent operations for right-sided NSCLC in 2 French surgical centers were prospectively entered and retrospectively reviewed. Demographic and pathologic characteristics of RML NSCLC were compared with other right-sided NSCLC. RESULTS This study included 3,234 right-sided and 211 RML (6.5%) NSCLC patients. After exclusion of 14 patients who underwent exploratory thoracotomy, patients were a mean age of 61.5 years, most RML resections occurred in men (134 [72.8%]), and most were lobectomies (wedge, n=4; lobectomy, n=102; bilobectomy, n=22; pneumonectomy, n=56). Pathologic analysis revealed adenocarcinoma in 88 patients (47.8%) and squamous cell carcinoma in 80 (43.5%). pStaging was stage I in 86 patients (46.7%), II in 42 (22.8%), III in 47 (25.5%), and IV in 9 (4.9%). Superior and inferior mediastinal N2 were found in 45.4% and 54.6% of patients, respectively, when 1 station was involved. When compared with other right-sided NSCLC, RML was characterized by higher T status and higher rates of bilobectomy (10.9% vs 5.6%, p=0.0017) and pneumonectomy (30.3% vs 22.3%, p=0.0071) but similar 5-year survival (47.4%). CONCLUSIONS Compared with other right-sided NSCLC, RML location is associated with a higher albeit limited rate of pneumonectomy.

Abstract
Thoracic surgeons are often asked to see patients with locally advanced primary lung cancer in whom the goal of treatment is palliation for relief of disabling symptoms. The last four decades have brought great changes in the care of patients with primary lung cancer. The goals of the treatment must be well-defined by the interdisciplinary team. The thoracic surgeon has to make the final decision on whether to consider an operation for palliation and what is the expectation of the recommended treatment.

Abstract
OBJECTIVES The standard surgical treatment for patients with non-small-cell lung cancer (NSCLC) is lobectomy with systematic nodal dissection (SND). Lobe-specific patterns of nodal metastases have been recognized, and lobe-specific SND (L-SND) has been reported. We performed L-SND depending on patient-related factors, such as age or the presence of diabetes or respiratory dysfunction, or in the context of specific tumour-related factors, such as the presence of a tumour with a wide area of ground-glass opacity. METHODS Between September 2002 and December 2008, 335 consecutive patients with clinical and intraoperative N0 NSCLC underwent curative lobectomies at Shizuoka Cancer Center Hospital. Among these 335 patients, 206 underwent SND (Group A) and 129 underwent L-SND. Of the 129 patients undergoing L-SND, 98 underwent L-SND due to patient-related factors (Group B) and 31 underwent L-SND due to tumour-related factors (Group C). RESULTS There were no significant differences in morbidity or blood loss between patients undergoing SND or L-SND, but there was a significant difference in the mean operative times. The 5-year disease-free survival (5-DFS) and 5-year overall survival (5-OS) of patients in Group C were 100%. Although the patients in Group B showed no significant difference in 5-DFS and 5-OS compared with Group A, patients in Group B had significantly more initial recurrence of mediastinal node cancer than did the Group A patients (P = 0.0050). CONCLUSIONS The recurrence of mediastinal node cancer in patients undergoing L-SND was significantly greater than that in those undergoing SND.

Abstract
Over the last few decades, the integration of chemotherapy and radiation has played a crucial role in the management of locally advanced non-small cell lung cancer (NSCLC). Locally advanced NSCLC is a very heterogeneous disease. Because of this heterogeneity, advanced NSCLC can be managed in various ways depending on the bulk of disease, the comorbidities of the patient, and the expertise and resources of the treating physicians and facilities. This review describes the evolution of current treatment strategies and predicted future changes for the management of locally advanced NSCLC.

Abstract
Size of early-stage lung cancer is important in the prognosis of patients. We examined the large population-based Surveillance, Epidemiology and End Results database to determine if tumor size was an independent risk factor of survival in patients undergoing lobectomy for N2 positive Stage IIIA nonsmall cell lung cancer (NSCLC). This study identified 1971 patients diagnosed with N2 positive Stage IIIA NSCLC, from 1998 to 2007, and who underwent lobectomy. Five tumor groups based on the seventh edition TNM lung cancer staging system (pathologic T1a 2 cm or less; T1b greater than 2 cm and 3 cm or less; T2a greater than 3 cm and 5 cm or less; T2b greater than 5 cm and 7 cm or less; T3 greater than 7 cm) were analyzed. Survival was reduced in patients with T3, T2a, and T2b tumors compared with patients with T1a and T1b ( P < 0.001). Survival estimates correlated with tumor size with poorer survival in T3 followed by T2b, T2a, and then T1b and T1a. Cohorts with T1a (hazard ratio [HR], 0.53; P = 0.01) and T1b (HR, 0.54; P = 0.01) were both found to have decreased hazard of death. Negative predictors of survival, in addition to increasing tumor size, included age and male gender, whereas positive predictors included tumor Grade I and upper lobe location. Increasing size of tumor is an independent negative risk factor for survival in patients undergoing lobectomy for N2 positive Stage IIIA NSCLC.

Abstract
The role of mediastinal lymph node dissection (MLND) during the resection of non-small-cell lung cancer is still unclear although most surgeons agree that a minimum of hilar and mediastinal nodes must be examined for appropriate pathological staging. Current surgical practices vary from visual inspection of the mediastinum with biopsy of only abnormal looking nodes to systematic mediastinal node sampling which is to the biopsy of lymph nodes from multiple levels whether they appear abnormal or not to MLND which involves the systematic removal of all lymph node bearing tissue from multiple sites unilaterally or bilaterally within the mediastinum. This review article looks at the evidence and arguments in favour of lymphadenectomy, including improved pathological staging, better locoregional control, and ultimately longer disease-free survival and those against which are longer operating time, increased operative morbidity, and lack of evidence for survival benefit.

Abstract
PURPOSE We designed a phase II trial to evaluate the efficacy and tolerability of high dose induction chemotherapy with carboplatin and paclitaxel with G-CSF and stem cell support followed by surgical resection and/or chest radiotherapy in patients with stage III non-small cell lung cancer (NSCLC). PATIENTS AND METHODS Patients had pathologically confirmed stage IIIA-IIIB NSCLC, adequate end-organ function, no prior chemotherapy or radiation, and performance status 0-1. Peripheral stem cells were mobilized with G-CSF stimulation on days 1-5 and collected prior to chemotherapy. Chemotherapy consisted of 2 cycles of paclitaxel 250 mg/m(2) over 3h and carboplatin at an AUC 18 on days 11 and 32, each followed by stem cell reinfusion. Stable and responding patients went on to surgical resection (in patients deemed resectable) followed by post-operative radiation, or to conventional chest radiotherapy to 66 Gy in unresectable patients. RESULTS Twelve patients (11 eligible) were accrued from 1996 to 1999. The 11 patients were predominately male (64%), white (82%), of performance status 0 (64%), and with weight loss less than 5% (55%). The median age was 51 (range 31-63). Ten (10) patients (91%) experienced grade 4 toxicity. There were no lethal toxicities. Grade 3-4 toxicities most commonly reported included: platelets (100%), lymphocytopenia (91%), leukopenia (91%), neutropenia (73%), anemia (55%), pain (45%), and nausea (27%). Three patients (27%) had a partial response to induction chemotherapy. Of the 11 patients, 7 underwent surgical exploration, and 10 received radiation. Two patients were completely resected, 3 patients had incomplete resections, and 2 patients had no resection. There were 4 complete responses and 3 partial responses following surgery and/or radiation. The median overall survival time was 17.8 months. The median failure-free survival time was 8.3 months. One-year and 2-year overall survival are estimated at 64% and 27%, respectively. CONCLUSIONS High dose induction chemotherapy with carboplatin and paclitaxel and stem cell support in patients with stage IIIA-IIIB NSCLC produced response rates and survival similar to standard therapy. Excessive toxicity (and cost) suggests that this approach does not merit further investigation.

Abstract
PURPOSE Present research aimed to explore the rationale of defining RIR operations by metastatic status of highest nodes. PATIENTS AND METHODS 549 surgical patients, bearing pN2-NSCLCs, were enrolled in the current study. R1/R2 nodes on the right side and L4 nodes on the left were taken as the highest mediastinal lymph nodes. The operations were defined "Complete Resection (CR)" if the highest nodes were negative. Operations were otherwise "Relative Incomplete Resections (RIR)" if the nodes were positive. Exclusion criteria included: metastatic carcinomas or small cell lung cancer, prior history of induction therapy, exploratory thoracotomy, palliative resection, and massive pleural dissemination, as well as cases without "highest" mediastinal nodal pathology. The survival rate was calculated using the life-table and Kaplan-Meier method. Comparisons between groups were calculated using the Log-rank test. RESULTS A total of 6865 lymph nodes (5705 mediastinal and 1160 regional, average 12.6±6.4 nodes for each patient) were removed. Total cases included 246 RIR (100 left and 146 right side) and 303 CR (108 left and 195 right). The overall 5-year survival rate was 22% and the median survival time was 28.29 months. Five-year survival rates of the CR and RIR group were statistically significant (29% and 13%, respectively p<0.0001). L4 and R1/R2 lymph nodes had similar position for defining RIR; no obvious survival difference was indicated between either side (p=0.464 in CR groups, p=0.647 in RIR groups). N2 subcategories and skip-metastasis were closely associated with highest nodal involvement (p<0.0001). Multivariate analysis showed CR/RIR assignment, tumor size, N2 disease stratification, pathological T status, and number of positive mediastinal nodes were risk factors for 5-year survival in the present case series. CONCLUSION Involvement of the highest mediastinal lymph nodes is highly predictive of poor prognosis and indicates an advanced stage of the disease. Therefore, it may be appropriate to assign R1/R2 or L4 as criterion for defining RIR or CR cases in surgical NSCLC cases.

Abstract
The lymphatic drainage of solid organ tumors crosses through the lymph nodes (LNs) whose tumoral involvement may still be considered as local disease. Concerning lung cancer, LN involvement may be intrapulmonary (N1), and mediastinal and/or extra-thoracic. More than 30 years ago, mediastinal involved LNs were all considered as N2, and outside the scope of surgery. In 1978, Naruke presented an original article entitled 'Lymph node mapping and curability at various levels of metastasis in resected lung cancer', demonstrating that N2 was not a contraindication to surgery in all patients. The map permitted to localize the favorable N2 on the lung cancer ipsilateral side of the mediastinum. Several maps ensued aiming to discriminate between right and left involvement (1983), and to distinguish N2 (ipsilateral) and N3 (contralateral) mediastinal LN involvement (1983, 1986). The last map (1997 regional LN classification) was recently replaced by a descriptive classification in anatomical zones. This new LN map of the TNM classification for lung cancer is a step toward using anatomical view points which might be the best way to better understand lung cancer lymphatic spread. Nowadays, the LNs are easily identified by current radiological imaging, and their resectability may be anticipated. Each LN chain may be removed by en-bloc lymphadenectomy performed during radical lung resection, a safe procedure which seems to be more oncological based than sampling, and which avoids the source of discrepancies pointed out during the labeling of LN stations by surgeons.

Abstract
Little is known about selective lymph node dissection in non-small cell lung cancer (NSCLC) patients. We sought to gain insight into subcarinal node involvement for its frequency and impact on outcome to evaluate whether it is valid to omit subcarinal lymph node dissection in upper lobe NSCLC patients. We reviewed node metastases distribution according to node region, tumor location, and histology among 1099 patients with upper lobe NSCLC. We paid special attention to subcarinal metastases patients without superior mediastinal node metastases, because their pathological stages would have been underdiagnosed if subcarinal node dissection had been omitted. We also assessed the outcome and the pattern of failure among subcarinal metastases patients. To identify subcarinal node involvement predictors, we analyzed 7 clinical factors. Subcarinal node metastases were found in 20 patients and were least frequent among squamous cell carcinoma patients (0.5%). Two of them were free from superior mediastinal metastases but died of the disease at 1 month and due to an unknown cause at 18 months, respectively. Seventeen of the 20 patients developed multi-site recurrence within 37 months. The 5-year survival rate of the 20 patients with subcarinal metastases was 9.0%, which was significantly lower than 32.0% of patients with only superior mediastinal metastases. Clinical diagnosis of node metastases was significantly predictive of subcarinal metastases. Subcarinal node metastases from upper lobe NSCLC were rare and predicted an extremely poor outcome. It appears valid to omit subcarinal node dissection in upper lobe NSCLC patients, especially in clinical N0 squamous cell carcinoma patients.

Abstract
Several issues regarding the surgical management of N2 disease remain unresolved. First, the anatomical attribution of a mediastinal nodal station, especially in certain areas (i.e., azygos recess), is a source of continuous debate. Second, the presence of occult N2, single or multilevel N2, bulky N2, the skip phenomenon and the observation of a different prognostic outlook for specific mediastinal nodal stations are all elements of discussion that cannot clarify whether stage IIIA-N2 non-small cell lung cancer is indeed a locally, albeit advanced, manifestation of the disease or the prodrome of an actual systemic dissemination. In this subset of patients lies the challenge for multidisciplinary treatment modalities, where the surgical role needs to be further defined in the context of an integrated collaborative effort with the medical oncologist and the radiotherapist.
