Abstract
The current S3 Lung Cancer Guidelines are edited with fundamental changes to the previous edition based on the dynamic influx of information to this field:The recommendations include de novo a mandatory case presentation for all patients with lung cancer in a multidisciplinary tumor board before initiation of treatment, furthermore CT-Screening for asymptomatic patients at risk (after federal approval), recommendations for incidental lung nodule management , molecular testing of all NSCLC independent of subtypes, EGFR-mutations in resectable early stage lung cancer in relapsed or recurrent disease, adjuvant TKI-therapy in the presence of common EGFR-mutations, adjuvant consolidation treatment with checkpoint inhibitors in resected lung cancer with PD-L1 ≥ 50%, obligatory evaluation of PD-L1-status, consolidation treatment with checkpoint inhibition after radiochemotherapy in patients with PD-L1-pos. tumor, adjuvant consolidation treatment with checkpoint inhibition in patients withPD-L1 ≥ 50% stage IIIA and treatment options in PD-L1 ≥ 50% tumors independent of PD-L1status and targeted therapy and treatment option immune chemotherapy in first line SCLC patients.Based on the current dynamic status of information in this field and the turnaround time required to implement new options, a transformation to a "living guideline" was proposed.

A Comparison of Total Thoracoscopic and Robotic Surgery for Lung Cancer Lymphadenectomy. Cancers (Basel) 2023; 15:3442. [PMID: 37444555 DOI: 10.3390/cancers15133442] [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: 05/17/2023] [Revised: 06/21/2023] [Accepted: 06/28/2023] [Indexed: 07/15/2023] Open
Abstract
BACKGROUND Robotic-assisted thoracic surgery (RATS) is used increasingly frequently in major lung resection for early stage non-small-cell lung cancer (NSCLC) but has not yet been fully evaluated. The aim of this study was to compare the surgical outcomes of lymph node dissection (LND) performed via RATS with those from totally thoracoscopic (TT) four-port videothoracoscopy. METHODS Clinical and pathological data were collected retrospectively from patients with clinical stage N0 NSCLC who underwent pulmonary resection in the form of lobectomy or segmental resection between June 2010 and November 2022. The assessment criteria were number of mediastinal lymph nodes and number of mediastinal stations dissected via the RATS approach compared with the four-port TT approach. RESULTS A total of 246 pulmonary resections with LND for clinical stages I-II NSCLC were performed: 85 via TT and 161 via RATS. The clinical characteristics of the patients were similar in both groups. The number of mediastinal nodes dissected and mediastinal stations dissected was significantly higher in the RATS group (TT: mean ± SD, 10.72 ± 3.7; RATS, 14.74 ± 6.3 [p < 0.001]), except in the inferior mediastinal stations. There was no difference in terms of postoperative complications. CONCLUSIONS In patients with early stage NSCLC undergoing major lung resection, the quality of hilomediastinal LND performed using RATS was superior to that performed using TT.

Abstract
SIGNIFICANCE OF LUNG CANCER Lung cancer has enormous socioeconomical impact on our society due to its high prevalence and mortality. About 59,700 new cases of lung cancer were forecasted for 2022. TNM SCHEME FOR STAGING Correct staging is the basis for therapy planning, prognosis estimation, and future analyses. Staging is performed using the TNM scheme from the Union for International Cancer Control (UICC). Involvement of lymph nodes is used to differentiate between stage IIB and IIIC. LYMPH NODE LEVELS FOR LUNG CANCER Knowledge of the intrathoracic lymph node levels is crucial for the exact classification and its involvement has direct implications on therapy. The International Association for the Study of Lung Cancer (IASLC) proposed a unified lymph node map with exact anatomic definitions, which is recommended by the German national lung cancer guideline. The extent of lymph node involvement is stratified into N0-N3. Different metastatic paths are known depending on the location of the primary tumor, but the burden of disease has a greater influence on survival, than the location of metastases. ASSESSING THE SPREAD OF LUNG CANCER Computed tomography can assess operability of the primary tumor safely in most cases. Invasive procedures to confirm the diagnosis by sampling tissue should be performed after noninvasive diagnostics. PRACTICAL RECOMMENDATION Systematic lymph node dissection for all patients with non-small cell lung cancer intended for curative resection is recommended in the current German national guideline for lung cancer.

Abstract
Background: While the thoracotomy approach was considered the gold standard until two decades ago, robotic surgery has increasingly strengthened its role in lung cancer treatment, improving patients’ peri-operative outcomes. In this study, we report our experience in robotic lobectomy for early-stage non-small cell lung cancer, with particular attention to oncological outcomes and nodal upstaging rate. Methods: We retrospectively reviewed patients who underwent lobectomy and radical lymphadenectomy at our Institute between 2016 and 2020. We selected 299 patients who met the inclusion criteria of the study. We analyzed the demographic features of the groups as well as their nodal upstaging rate after pathological examination. Then, we analyzed disease-free and overall survival of the entire enrolled patient population and we compared the same oncological outcomes in the upstaging and the non-upstaging group. Results: A total of 299 patients who underwent robotic lobectomy were enrolled. After surgery, 55 patients reported nodal hilar or mediastinal upstaging. The 3-year overall survival of the entire population was 82.8%. The upstaging group and the non-upstaging group were homogeneous for age, gender, smoking habits, clinical stage, tumor site, tumor histology. The non-upstaging group had better OS (p = 0.004) and DFS (p < 0.0001). Conclusion: Our results show that robotic surgery is a safe and feasible approach for the treatment of early-stage NSCLC, especially for its accuracy in mediastinal lymphadenectomy. The oncological outcomes were encouraging and consistent with previous findings.

Abstract
Introduction: The standard surgical procedures for patients with early-stage NSCLC is lobectomy-associated radical lymphadenectomy performed by using the thoracotomy approach. In the last few years, minimally invasive techniques have increasingly strengthened their role in lung cancer treatment, especially in the early stage of the disease. Although the lobectomy technique has been accepted, controversy still surrounds lymph node dissection. In our study, we analyze the rate of upstaging early non-small cell lung cancer patients who underwent radical surgical treatment using the robotic and the VATS techniques compared to the standard thoracotomy approach. Methods and Materials: We retrospectively reviewed patients who underwent a lobectomy and radical lymphadenectomy at our Institute between 2010 and 2019. We selected 505 patients who met the inclusion criteria of the study: 237 patients underwent robotic surgery, 158 patients had thoracotomy, and 110 patients were treated with VATS. We analyzed the demographic features between the groups as well as the nodal upstaging rate after pathological examination, the number of dissected lymph nodes and the ratio of dissected lymph nodes to metastatic lymph nodes of the three groups. Results: The patients of the three groups were homogenous with respect to age, sex, and histology. The postoperative major morbidity rate was significantly higher in the thoracotomy group, and hospital stay was significantly longer. The percentage of the mediastinal nodal upstaging rate and the number of dissected lymph nodes was significantly higher in the robotic group compared with the VATS group. The ratio of dissected lymph nodes to metastatic lymph nodes was significantly lower compared with the VATS group and the thoracotomy group. Discussion: The prognostic impact of the R(un) status is still highly debated. A surgical approach that allows better results in terms of resection has still not been defined. Our results show that robotic surgery is a safe and feasible approach especially regarding the accuracy of mediastinal lymphadenectomy. These findings can lead to defining a more precise pathological stage of the disease and, if necessary, to more accurate postoperative treatment.

External validation of the N descriptor in the proposed tumour-node-metastasis subclassification for lung cancer: the crucial role of histological type, number of resected nodes and adjuvant therapy. Eur J Cardiothorac Surg 2021; 58:1236-1244. [PMID: 32770184 DOI: 10.1093/ejcts/ezaa215] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2020] [Revised: 04/27/2020] [Accepted: 05/01/2020] [Indexed: 12/15/2022] Open
Abstract
OBJECTIVES Overlapping survival curves for N1b (multiple N1 stations), N2a2 (single N2 station + N1 involvement) and N2a1 (skip N2 metastasis) limit the current tumour-node-metastasis (TNM) node (N) subclassification for node involvement. We validated externally the proposed subclassification. METHODS Clinical records from a multicentric database comprising 1036 patients with pulmonary adenocarcinoma (ADC) or squamous cell carcinoma with N1/N2 involvement who underwent, from January 2002 to December 2014, complete lung resections were retrospectively reviewed. Patients were categorized according to the 8th TNM N subclassification proposal. Histological type, number of resected nodes (#RN) and adjuvant therapy (ADJ) were considered limiting factors. RESULTS No difference in the 5-year overall survival (-OS) was noted between N1b and N2a1 (49.6% vs 44.8%, P = 0.72); instead, the 5-year-OS was significantly improved in patients with squamous cell carcinoma (63% in N1b vs 30.7% in N2a1, P = 0.04). In patients with ADC, the 5-year-OS was better in those with N2a1 than with N1b (50.6% vs 37.5%, P = 0.09). When we compared N1b with N2a2, the 5-year-OS was statistically significant (49.6% vs 32.8%, P = 0.02); considering only patients with squamous cell carcinoma (63% vs 25.8%, P = 0.003), #RN >10 (63.2% vs 35.3%, P = 0.05) and without ADJ (56.4% vs 24.5%, P = 0.02), the 5-year-OS was significantly different. Differences were not significant for ADC, #RN <10 and ADJ. Finally, the 5-year-OS was statistically significant when we compared N2a1 with N2a2 of the total cohort (44.8% vs 32.8%, P = 0.04), in ADC (5-year-OS 50.6% vs 36.5%, P = 0.04) and #RN >10 (5-year-OS 49.8% vs 32.1%, P = 0.03) without ADJ. CONCLUSIONS Histological type, ADJ and #RN are relevant prognostic factors in N + non-small-cell lung cancer. Considering these results, we may better interpret the prognosis prediction limits of the proposed 8th TNM subclassification for the N descriptor.

Abstract
BACKGROUND Unexpected N2 involvement occurs in approximately 10% to 20% of patients with non-small-cell lung cancer (NSCLC) and patients' prognostic factors remain unclear. The aim of this study was to evaluate prognostic factors in these patients. METHODS From January 2002 to December 2012, we retrospectively analyzed data of 550 patients with NSCLC with preoperative negative, but pathologic positive N2 involvement, who underwent anatomical lung resection and hilo-mediastinal lymphadenectomy, obtained from 6 institutions. An established prognostic factor panel and N2-type involvement were correlated to overall (OS), cancer-specific (CSS), and disease-free survival (DFS) using multivariate Cox Regression model. The following lymph node patterns were analyzed: number of resected nodes (#RNs), metastatic nodes (#MNs), ratio between #MNs and #RNs (NR), N2 subgroups proposed for the eighth TNM edition, and lobe-specific versus nonspecific metastasis. RESULTS Regarding our cohort, 419 patients were staged IIIA (T1-2N2), 131 IIIB (T3-4 N2), 113 pT1, 306 pT2, 94 pT3, and 37 pT4; 5-year OS, DFS, and CSS were 34.1%, 20.1%, and 64.6%, respectively. Independent prognostic factor for OS, in the multivariable analysis, were as follows: NR <17% (P = .009), proposed N2 classification subgroups (P = .014), age <66 (P < .001), and pT (P = .005); for DFS: NR <17% (P = .003), adjuvant treatment (P = .026), and pT (P = .026); and for CSS: NR <17% (P = .008), grading (P = .001), and adjuvant treatment (P < .001). CONCLUSION Our study confirms that adjuvant therapy is fundamental and NR, in patients with unexpected N2 involvement, has a strong prognostic factor. In particular, a NR cutoff value of 17% could predict OS, DFS, and CSS in patients with NSCLC.

Abstract
OBJECTIVES To re-examine the evidence for recommendations for complete dissection versus sampling of ipsilateral mediastinal lymph nodes during lobectomy for cancer. METHODS We searched for randomized trials of systematic mediastinal lymphadenectomy versus mediastinal sampling. We performed a textual analysis of the authors' own starting assumptions and conclusion. We analysed the trial designs and risk of bias. We extracted data on early mortality, perioperative complications, overall survival, local recurrence and distant recurrence for meta-analysis. RESULTS We found five randomized controlled trials recruiting 1980 patients spanning 1989-2007. The expressed starting position in 3/5 studies was a conviction that systematic dissection was effective. Long-term survival was better with lymphadenectomy compared with sampling (Hazard Ratio 0.78; 95% CI 0.69-0.89) as was perioperative survival (Odds Ratio 0.59; 95% CI 0.25-1.36, non-significant). But there was an overall high risk of bias and a lack of intention to treat analysis. There were higher rates (non-significant) of perioperative complications including bleeding, chylothorax and recurrent nerve palsy with lymphadenectomy. CONCLUSIONS The high risk of bias in these trials makes the overall conclusion insecure. The finding of clinically important surgically related morbidities but lower perioperative mortality with lymphadenectomy seems inconsistent. The multiple variables in patients, cancers and available treatments suggest that large pragmatic multicentre trials, testing currently available strategies, are the best way to find out which are more effective. The number of patients affected with lung cancer makes trials feasible.

Abstract
It is still debatable whether complete mediastinal lymph node dissection (MLND) is associated with better survival than mediastinal lymph node sampling (MLNS) in surgical treatment of nonsmall cell lung cancer (NSCLC). We aimed to assess the impact of lymph node dissection on long-term survival among stage I NSCLC patients.In this cohort study, 317 stage I NSCLC Chinese patients in Shanghai Chest Hospital were followed up for at least 10 years to evaluate the impact of different lymph node dissection modes on their survival. Among them, 161 patients were in the MLND group and 156 in the MLNS group. Overall survival and median survival times were calculated for the 2 groups. The association between lymph node dissection and the survival of NSCLC patients was assessed using Cox proportional-hazard models.Patients in the MLND group presented better survival (median survival time = 154.67 months) than those in the MLNS group (median survival time = 124.67 months). The MLNS had higher mortality than the MLND group, with the crude hazard ratio of the MLNS group relative to the MLND group as 1.32 (95% confidence interval [CI] 0.97, 1.78). After adjusting for age and sex, the association between lymph node dissection and mortality (hazard ratio 1.36, 95% CI 1.00, 1.84) was statistically significant (P = .047). Further adjusting for baseline clinical characteristics, the association (hazard ratio 1.40, 95% CI 1.02, 1.92) remained statistically significant (P = .036). The association between lymph node dissection mode and mortality was strong among patients with tumor size between 2.0 and 3.0 cm (hazard ratio 2.79, 95% CI 1.45, 5.37).We found that the MLND was associated with better survival for patients with early-stage NSCLC, compared with the MLNS. The effects of MLND on survival may depend on tumor size. Our findings have important implications in the treatment of early-stage NSCLC. Further prospective studies with a large sample size are needed to confirm our findings.

Abstract
Quality of care (QoC) has a central role in our health care system. The aim of this review is to present a set of evidence-based quality indicators for the surgical treatment and postoperative management of lung cancer. A search was performed through PubMed, Embase and the Cochrane library database, including English literature, published between 1980 and 2012. Search terms regarding 'lung neoplasms', 'surgical treatment' and 'quality of care' were used. Potential QoC indicators were divided into structure, process or outcome measures and a final selection was made based upon the level of evidence. High hospital volume and surgery performed by a thoracic surgeon, were identified as important structure indicators. Sleeve resection instead of pneumonectomy and the importance of treatment within a clinical care path setting were identified as evidence-based process indicators. A symptom-based follow-up regime was identified as a new QoC indicator. These indicators can be used for registration, benchmarking and ultimately quality improvement in lung cancer surgery.

Abstract
Surgery is the treatment of choice in patients with early stage NSCLC. However, the results remain poor in these patients. Lymph node involvement is the main prognostic factor in patients with NSCLC, but there is still no clear definition of the number of nodes required to consider a lymphadenectomy as complete. Although there is no defined minimum number of lymph nodes required for a complete lymphadenectomy, there are some recommendations to perform this procedure, published by different scientific societies. Current practice in thoracic surgery regarding lymphadenectomy, differs on some points from the guidelines recommendations, with data regarding patients with no mediastinal assessment between 30-45% according to some of the published data. Different studies have probed the fact that the probability of finding a positive node increases with the number of lymph nodes analyzed. Therefore, a complete lymphadenectomy provides proper staging, which helps to identify the patient's real prognosis. Several nonrandomized studies and retrospective series have shown that survival increases in the group of patients with a higher number of lymph nodes removed. There is no contraindication to performing a complete lymphadenectomy. The increase in survival in patients with a complete lymphadenectomy may be due to more accurate staging. Therefore, complete lymphadenectomy should be mandatory even in early stage patients.

Abstract
BACKGROUND The presence of tumor metastases in the mediastinum is one of the most important elements in determining the optimal treatment strategy in patients with non-small cell lung cancer. This review is aimed at examining the current strategies for investigating lymph node metastases corresponding to an "N2" classification delineated by The International Staging Committee of the International Association for the Study of Lung Cancer (IASLC). METHODS Extensive review of the existing scientific literature related to the investigation of mediastinal lymph node metastases was undertaken in order to summarize and report current best practices. CONCLUSIONS N2 disease is very heterogeneous requiring multiple modalities for thorough investigation. New research is now focusing on better identifying, defining, and classifying lymph node metastases in the mediastinum. Molecular staging and sub-classifying mediastinal lymph node metastases are being actively researched in order to provide better prognostic value and to optimize treatment strategies. Non-invasive imaging, such as PET/CT and minimally invasive techniques such as endobronchial and endoscopic ultrasound guided biopsy, are now the lead investigative methods in evaluating the mediastinum for metastatic presence.

Abstract
BACKGROUND Lobectomy with complete mediastinal lymphadenectomy is considered standard for patients with early-stage non-small cell lung cancer (NSCLC). However, the benefits of complete lymphadenectomy are unproven. There is evidence suggesting a predictable pattern of mediastinal nodal drainage. This study analyzed the frequency and pattern of mediastinal nodal disease and its impact on outcome in patients with early-stage NSCLC. METHODS Patients with clinical N0/N1 NSCLC staged with CT scans and PET scans were identified. Disease involvement of resected nodal stations was recorded. Patterns of recurrence in patients who underwent lobectomy with complete mediastinal systematic lymph node sampling (SLNS) were compared with those who underwent lobe-specific mediastinal SLNS. RESULTS From July 2004 to April 2011, 370 patients were identified. Complete SLNS was performed in 282 patients. Fifteen patients (5.3%) in the group with complete SLNS were found to have N2 disease after pathologic evaluation. Patients with left-sided tumors were more likely to have pathologic N2 disease than were patients with right-sided tumors (P = .03). Only one patient (0.36%) had positive N2 disease in the distal mediastinum while skipping lobe-specific mediastinal nodes. In addition, patients with complete SLNS had a rate of recurrence similar to that of the group that had lobe-specific mediastinal evaluation (20.6% vs 18.2%, P = .68). CONCLUSIONS Mediastinal N2 metastases follow predictable lobe-specific patterns in patients with negative preoperative CT scans and PET scans. Lobe-specific N2 nodal evaluation results in a recurrence rate similar to that of complete mediastinal evaluation. Lobe-specific mediastinal nodal evaluation appears acceptable in patients with early-stage NSCLC.

Abstract
OBJECTIVES Stage III non-small cell lung cancer (NSCLC) describes a heterogeneous population with disease presentation ranging from apparently resectable tumors with occult microscopic nodal metastases to unresectable, bulky nodal disease. This review updates the published clinical trials since the last American College of Chest Physicians guidelines to make treatment recommendations for this controversial subset of patients. METHODS Systematic searches were conducted through MEDLINE, Embase, and the Cochrane Database for Systematic Review up to December 2011, focusing primarily on randomized trials, selected meta-analyses, practice guidelines, and reviews. RESULTS For individuals with stage IIIA or IIIB disease, good performance scores, and minimal weight loss, treatment with combined chemoradiotherapy results in better survival than radiotherapy alone. Consolidation chemotherapy or targeted therapy following definitive chemoradiation for stage IIIA is not supported. Neoadjuvant therapy followed by surgery is neither clearly better nor clearly worse than definitive chemoradiation. Most of the arguments made regarding patient selection for neoadjuvant therapy and surgical resection provide evidence for better prognosis but not for a beneficial impact of this treatment strategy; however, weak comparative data suggest a possible role if only lobectomy is needed in a center with a low perioperative mortality rate. The evidence supports routine platinum-based adjuvant chemotherapy following complete resection of stage IIIA lung cancer encountered unexpectedly at surgery. Postoperative radiotherapy improves local control without improving survival. CONCLUSIONS Multimodality therapy is preferable in most subsets of patients with stage III lung cancer. Variability in the patients included in randomized trials limits the ability to combine results across studies and thus limits the strength of recommendations in many scenarios. Future trials are needed to investigate the roles of individualized chemotherapy, surgery in particular cohorts or settings, prophylactic cranial radiation, and adaptive radiation.

Abstract
The extent of mediastinal lymph node assessment during surgery for non-small cell cancer remains controversial. Different techniques are used, ranging from simple visual inspection of the unopened mediastinum to an extended bilateral lymph node dissection. Furthermore, different terms are used to define these techniques. Sampling is the removal of one or more lymph nodes under the guidance of pre-operative findings. Systematic (full) nodal dissection is the removal of all mediastinal tissue containing the lymph nodes systematically within anatomical landmarks. A Medline search was conducted to identify articles in the English language that addressed the role of mediastinal lymph node resection in the treatment of non-small cell lung cancer. Opinions as to the reasons for favoring full lymphatic dissection include complete resection, improved nodal staging and better local control due to resection of undetected micrometastasis. Arguments against routine full lymphatic dissection are increased morbidity, increase in operative time, and lack of evidence of improved survival. For complete resection of non-small cell lung cancer, many authors recommend a systematic nodal dissection as the standard approach during surgery, and suggest that this provides both adequate nodal staging and guarantees complete resection. Whether extending the lymph node dissection influences survival or recurrence rate is still not known. There are valid arguments in favor in terms not only of an improved local control but also of an improved long-term survival. However, the impact of lymph node dissection on long-term survival should be further assessed by large-scale multicenter randomized trials.

Abstract
OBJECTIVES We aimed to analyze the accuracy of video-assisted mediastinoscopic lymphadenectomy (VAMLA) as a tool for preoperative staging and the impact of the technique on survival in patients with non-small cell lung cancer (NSCLC) undergoing pulmonary resection. METHODS Between May 2006 and December 2010, 433 patients underwent pulmonary resection for NSCLC, 89 (21%) had VAMLA before resection and 344 (79%) had standard mediastinoscopy. The patients who had negative VAMLA/mediastinoscopy results underwent anatomic pulmonary resection and systematic lymph node dissection. RESULTS The median and mean numbers of resected lymph node stations were 5 and 4.9 in the VAMLA group and 4 and 4.2 in the mediastinoscopy group (P = .9). The mean number of lymph nodes per biopsy specimen using standard mediastinoscopy was 10.1, whereas it was 30.4 using VAMLA (P < .001). VAMLA unveiled N2 or N3 disease in 30 (33.7%) and in 6 (6.7%) of patients, respectively. The negative predictive value, sensitivity, false-negative value, and accuracy of VAMLA were statistically higher in the VAMLA groups compared with those of standard mediastinoscopy. The 5-year survival was 90% for VAMLA patients and 66% for mediastinoscopy patients (P = .01). By multivariable analysis, VAMLA was associated with better survival (odds ratio, 1.34; 95% confidence interval, 1.1-3.2; P = .02). CONCLUSIONS VAMLA was associated with improved survival in NSCLC patients who had resectional surgery.

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
INTRODUCTION Visceral pleural invasion, which is defined as tumor extension beyond the elastic lamina, is one of the most important prognostic factors in patients who have undergone curative resection for non-small cell lung cancer. However, in pathologic slides, pleural elastic lamina could not be found in the hilar region in which the pleura is reflected. Till date, when cancer cells are seen in this region, a basical agreement dealing with T factor is controversial among pathologists. The purpose of this study is to evaluate the significance of tumor invasion of that region as a prognostic factor. METHODS We reviewed 91 cases of surgically resected lung cancer in which invasion of the hilar region was visible macroscopically. By microscopic examination, we divided them into three groups: a group in which no cancer cells are seen in the soft tissue beyond the hilar region (group A), a group in which cancer cells are seen in the soft tissue beyond the hilar region (group B), and a group in which cancer cells could not be seen in the soft tissue beyond the hilar region but invade into the mediastinal visceral pleura at some other site (group C). We then evaluated the clinicopathologic characteristics of the patients and their outcome. RESULTS There was no statistically significant difference in the 5-year overall survival rate or disease-free survival rate between group A and group B (overall: 55 versus 48%; disease free: 43 versus 42%), but disease-free survival of group C was significantly lesser than that of group A and group B (A versus C: p = 0.022; B versus C: p = 0.040). CONCLUSION Tumor invasion of the soft tissue beyond hilar region would not be a prognostic factor in patients who have undergone curative resection for primary lung cancer, although investigation of larger number of cases will be needed to confirm the validity of our conclusion.

Abstract
PURPOSE Surgical resection remains the most effective treatment in patients with pulmonary metastasis of renal cell carcinoma. To our knowledge the prognostic significance of mediastinal and hilar lymph node metastasis during pulmonary metastasectomy in patients with renal cell carcinoma is unknown. We analyzed the value of computerized tomography to predict mediastinal/hilar lymph node involvement as well as the impact of systematic lymphadenectomy on survival in patients with pulmonary renal cell carcinoma metastasis. MATERIALS AND METHODS We analyzed survival in 110 patients who underwent resection of pulmonary metastasis of renal cell carcinoma using the Kaplan-Meier method. Multivariate analysis was done by Cox regression analysis. RESULTS Lymph node metastasis was histologically proved in 35% of patients. Metastasis was not associated with initial tumor grade, lymph node status, the number of pulmonary metastases or recurrent pulmonary metastasis. Computerized tomography had 84% sensitivity and 97% specificity to predict lymph node metastasis. Sensitivity was markedly better for detecting mediastinal than hilar lymph node metastasis (90% vs 69%). Patients with lymph node metastasis had significantly shorter median survival than patients without lymph node metastasis (19 vs 102 months, p <0.001). Multivariate analysis revealed that tumor infiltrated mediastinal lymph nodes were an independent prognostic factor for patient survival. Match paired analysis showed that after lymph node dissection patients showed a trend toward improved survival. CONCLUSIONS Mediastinal and hilar lymph node metastases significantly correlate with decreased survival. Systematic lymphadenectomy provides valuable information on staging and prognosis in patients with pulmonary metastasis of renal cell carcinoma, and may prolong survival.

Abstract
BACKGROUND Lymph node status is a major determinant of stage and survival in patients with lung cancer; however, little information is available about the expected yield of a mediastinal lymphadenectomy. METHODS The American College of Surgeons Oncology Group Z0030 prospective, randomized trial of mediastinal lymph node sampling vs complete mediastinal lymphadenectomy during pulmonary resection enrolled 1,111 patients from July 1999 to February 2004. Data from 524 patients who underwent complete mediastinal lymph node dissection were analyzed to determine the number of lymph nodes obtained. RESULTS The median number of additional lymph nodes harvested from a mediastinal lymphadenectomy following systematic sampling was 18 with a range of one to 72 for right-sided tumors, and 18 with a range of four to 69 for left-sided tumors. The median number of N2 nodes harvested was 11 on the right and 12 on the left. A median of at least six nodes was harvested from at least three stations in 99% of patients, and 90% of patients had at least 10 nodes harvested from three stations. Overall, 21 patients (4%) were found to have occult N2 disease. CONCLUSIONS Although high variability exists in the actual number of lymph nodes obtained from various nodal stations, complete mediastinal lymphadenectomy removes one or more lymph nodes from all mediastinal stations. Adequate mediastinal lymphadenectomy should include stations 2R, 4R, 7, 8, and 9 for right-sided cancers and stations 4L, 5, 6, 7, 8, and 9 for left-sided cancers. Six or more nodes were resected in 99% of patients in this study. TRIAL REGISTRY ClinicalTrials.gov; No.: NCT00003831; URL: clinicaltrials.gov.

Abstract
BACKGROUND The seventh edition of the tumor, node, metastasis Classification of Malignant Tumors is due to be published in 2009. The recommendations of International Association for the Study of Lung Cancer for changes to the T descriptors have been published. We combined this new parameter with other well-established prognostic factors and performed multivariate survival analyses to validate its value in Chinese stage I non-small cell lung cancer (NSCLC). METHODS We try to validate the new staging project in 325 patients who underwent complete surgical resection for stage I NSCLC in Single Institution of Shanghai Chest Hospital from 1998 to 2003. Variables in the analysis included age, gender, performance status, history of smoking, pathologic type, type of resection (pneumonectomy, lobectomy, and bilobectomy), tumor size (greatest dimension of tumor), T-status (T1 or T2), type of lymph node resection (systematic mediastinal lymphadenectomy or mediastinal lymph node sampling), lymphovascular vessel invasion, and adjuvant chemotherapy. RESULTS The 5-year overall survival (OS) of patients whose tumor measured no larger than 2 cm in largest diameter or larger than 2 cm but no larger than 3 cm were 75.49 and 74.58%, respectively. For those with tumors measured larger than 3 cm but smaller than 5 cm or larger than 5 cm but smaller than 7 cm were 60.87 and 55.63%. The 5-year OS of patients whose tumor measured larger than 7 cm was 46.15% (p = 0.025). The 5-year disease-free survival rates of patients whose tumor measured no larger than 2 cm in largest diameter or larger than 2 cm but no larger than 3 cm were 67.65 and 66.67%, respectively. For those with tumors measured larger than 3 cm but smaller than 5 cm or larger than 5 cm but smaller than 7 cm were 53.14 and 52.63%. The 5-year disease-free survival rate of patients whose tumor measured larger than 7 cm was 30.77% (p = 0.009). Multivariate analyses revealed that age, gender, type of resection (pneumonectomy, lobectomy, and bilobectomy), tumor size (greatest dimension of tumor), type of lymph node resection (systematic mediastinal lymphadenectomy or mediastinal lymph node sampling), and lymphovascular vessel invasion were significant predictive factors for OS. CONCLUSIONS The tumor size is a significant independent prognostic factors in stage I NSCLC.

Abstract
BACKGROUND AND OBJECTIVE The aim of this study was to determine the prognostic value of molecular markers (proteins) of different paths of lung cancer development in patients with non small cell lung carcinoma (NSCLC) in initial stages. MATERIAL AND METHOD Observational, cohort study in patients with NSCLC that was initially treated surgically in our hospital between October 1993 and September 1997. Thirty-two proteins were selected. The study consisted of the elaboration of tissue arrays with samples from resected tumour, using a semiquantitative immunohistochemical study. A prognosis analysis was done with the expression of each protein and calculation of the overall 5-year survival rate. The Wilcoxon-Gehan and Log-Rank tests were used for statistical comparisons, with p<.05 being considered to indicate a significant result. RESULTS One hundred and forty six patients were studied. The overall 5-year survival rate was 37.7%. From 32 proteins studied, three were statistically associated with overall 5-year survival rate. RB protein expression in resected NSCLC was a positive prognostic factor (P=.01). P27 (P=.03) and Ki67 (P=.04) expression in resected NSCLC were negative prognostic factors. There was no protein with prognostic value in epidermoid tumours. CONCLUSIONS We found three proteins with long-term prognostic value in the long-term in the general population and five adenocarcinoma prognostic proteins in our study of resected non-small cell lung cancer (NSCLC). In the future, genetic-molecular factors should be included along with anatomical (TNM staging) and clinical factors in a multidimensional lung cancer staging.

Abstract
Staging of the mediastinum is an integral component of the operative treatment of NSCLC. Systematic sampling and systematic lymph node dissection provide similar and accurate staging information. Systematic lymph node dissection is more likely to identify multiple levels of N2 disease, however, and may be associated with improved survival. During surgery for a right lung cancer, at least mediastinal lymph node levels 4 should be sampled or dissected. When removing a left lung cancer, at least nodal levels 5 and 7 should be assessed. Although every effort should be made to identify N2 disease before surgery, if intraoperative metastases to mediastinal lymph nodes are discovered, the planned operation should proceed. Cisplatin-based adjuvant chemotherapy has moderate but proven survival benefit after resection of N2 disease. The role of PORT remains uncertain.

Abstract
OBJECTIVE Cytologic micropapillary clusters (MPCs) are round, three-dimensional and cohesive clusters of lung cancer cells with a pseudopapillary configuration. Recently, we demonstrated that MPCs from early stage lung adenocarcinomas can be considered as useful aids to assessing prognosis. We here demonstrate that stage I lung adenocarcinomas found to be positive for MPCs in preoperative cytologic approaches are high risk for lymphatic spread. METHODS The clinicopathologic characteristics, metastatic status of dissected lymph nodes, vascular infiltration and presence of MPCs in preoperative cytologic specimens in 209 patients with clinical stage I lung adenocarcinomas undergoing complete surgical resection during 2004-2006 were reviewed. RESULTS Thirty-eight patients (18%) had positive MPC findings; 21 patients with clinical stage IA and 17 with stage IB. Significant associations with postoperative stages IA and IB, frequent lymph node metastasis and venous infiltration on pathologic examination were observed (P<0.05). In particular, 50% of clinical stage I patients with MPCs demonstrated advance in the postoperative stage of disease. CONCLUSIONS MPCs may be a manifestation of aggressive behavior, as evidenced by frequent lymph node metastasis, of clinical stage I lung adenocarcinomas. Preoperative cytologic detection of MPCs, therefore, should alert the surgeon to the probability of lymph node metastases.

Abstract
There is a great deal of concern about metastasis of lung cancer to regional lymph nodes, due partly to the work of groups of thoracic surgeons in Japan and North America beginning in the 1970s. The classification of regional lymph node stations for lung cancer staging published by Mountain and Dresler has been widely adopted for more than ten years. Anatomic landmarks for 14 levels of intrapulmonary, hilar, and mediastinal lymph nodes stations are designated. Skip transfer and occult lymph node metastasis, confirmed by studies regarding the mode of spread of intrathoracic lymphatic metastasis, are two theoretical bases for complete mediastinal lymphadenectomy of lung cancer. However, whether or not the degree of the dissection influences prognosis, the role of systematic nodal dissection (SND) vs mediastinal lymph node sampling (MLD) in resectable non-small cell lung cancer (NSCLC) remains controversial. A systematic literature search was performed to identify relevant reports, making full use of the 'Cited by,' 'Related Records,' 'References,' and 'Author Index' functions in the PubMed and ISI Web of Science databases. This paper presents a review of the role of mediastinal lymph node distribution and methods of determining suitability for hilar and mediastinal lymphadenectomy based on the four subsets of stage IIIA-N2, balancing the cost vs effect of mediastinal lymph node dissection in resectable NSCLC, focusing on the stage migration bias in clinical trials comparing SND and MLS, recommending a reasonable node dissection sequence, improving the prospects for the perioperative anti-tumor therapy based on mediastinal lymphadenectomy, and evaluating the various preoperative staging techniques. Finally, we believe that, besides the role of complete resection and accurate staging, the complete mediastinal lymphadenectomy is the core component of the lung cancer multidisciplinary therapy, and suggest that the values of lymphadenectomy should be further assessed using decision-tree analysis based on large-scale prospective randomized trials and pooled analysis to evaluate the costs vs effects.

Abstract
It has been proved with acceptable certainty that MLND does not increase complications in lung cancer surgery and improves the accuracy of staging. This applies to lung cancer at all resectable stages. As far as survival is concerned, statistically significant differences have been suggested by some authors and are more evident for early stages. Stage I NSCLC, a local disease, may profit from lymph node dissection, a procedure that can effectively control local tumor, reduce local recurrence, and improve long-term survival.

Abstract
OBJECTIVE To describe a series of cases of bronchioloalveolar carcinoma (BAC) treated surgically between 1993 and 1997 in the 19 hospitals that make up the Bronchogenic Carcinoma Cooperative Group of the Spanish Society of Pulmonology and Thoracic Surgery (GCCB-S). PATIENTS AND METHODS From a total of 2,944 cases of non-small cell lung cancer (NSCLC), 82 (3%) were BAC. The clinical characteristics and prognosis of patients with BAC were compared with those of the remaining 2,862 patients with NSCLC. RESULTS The percentage of men was lower for BAC than for other types of NSCLC (64.6% compared with 93.5%; P< .001) and BAC was associated with less comorbidity (50% vs 62%; P< .05), particularly in terms of chronic obstructive pulmonary disease (33% vs 47.2%; P< .05). Other characteristics showing significant differences were the higher frequency of BAC as a chance finding and the lower likelihood of weight loss or reduced performance status at the time of diagnosis. Classification as stage cI was significantly more common in patients with BAC (87% vs 75%; P.001), and this difference between groups was more pronounced for stage pI (68.5% vs 47%; P< .01). Only taking into account patients classified as stage pI with complete resection of NSCLC and following exclusion of operative mortality, patients with BAC presented an overall 5-year survival of 65% (95% confidence interval [CI], 51%-79%), compared with a significantly lower survival of 53% (95% CI, 50%-56%; P< .05) in patients with other forms of NSCLC. CONCLUSIONS In Spain, among cases of lung cancer treated by surgery, BAC is very rare (3%) and displays clinical characteristics that are different from other forms of NSCLC. Controlling for the most basic prognostic factors (stage pI and complete resection), survival is significantly higher for BAC.

Abstract
BACKGROUND Surgery is considered the treatment of choice for patients with resectable stage I and II (and some patients with stage IIIA) non-small cell lung cancer (NSCLC), but there have been no previously published systematic reviews. METHODS A systematic review and meta-analysis of randomised controlled trials was conducted to determine whether surgical resection improves disease specific mortality in patients with stages I-IIIA NSCLC compared with non-surgical treatment, and to compare the efficacy of different surgical approaches. RESULTS Eleven trials were included. No studies had untreated control groups. In a pooled analysis of three trials, 4 year survival was superior in patients undergoing resection with stage I-IIIA NSCLC who had complete mediastinal lymph node dissection compared with lymph node sampling (hazard ratio estimated at 0.78 (95% CI 0.65 to 0.93)). Another trial reported an increased rate of local recurrence in patients with stage I NSCLC treated with limited resection compared with lobectomy. One small study reported a survival advantage among patients with stage IIIA NSCLC treated with chemotherapy followed by surgery compared with chemotherapy followed by radiotherapy. No other trials reported significant improvements in survival after surgery compared with non-surgical treatment. CONCLUSION It is difficult to draw conclusions about the efficacy of surgery for locoregional NSCLC because of the small number of participants studied and methodological weaknesses of the trials. However, current evidence suggests that complete mediastinal lymph node dissection is associated with improved survival compared with node sampling in patients with stage I-IIIA NSCLC undergoing resection.

Abstract
OBJECTIVE The experiences published by various groups have re-opened the debate on the role of surgery in the management of patients with small cell lung cancer, especially in those with early stage disease (T1-T2 N0). Our study reports the survival rate of 47 patients with small cell lung cancer treated surgically. PATIENTS AND METHODS Ours is a prospective study that selected patients with lung cancer recommended for surgery (n=2994) between 1993 and 1997 based on operability criteria accepted by the Bronchogenic Carcinoma Cooperative Group of the Spanish Society of Pneumology and Thoracic Surgery. We report the clinical as well as pathological stages of the patients with small cell lung cancer (n=47), later analysing the 5-year survival rate after surgery using the Kaplan-Meier method. RESULTS In 31 patients (66%), resection was complete; 3 patients (6%) received induction treatment and 30 (64%) adjuvant treatment. Five years later, 26% (95% CI 12-40%) of the patients that received surgical treatment were still alive. When we analysed the patients that underwent complete resection, 31% (95% CI 13-49%) survived 5 years or more. In patients at stage Ip (n=15), 36% (95% CI 11-61%) were still living after 5 years. CONCLUSION Until future studies compare surgery plus chemotherapy versus chemotherapy and radiotherapy, it seems reasonable to offer surgical treatment to those patients with early stage small cell lung cancer (T1-T2-N0).

Abstract
OBJECTIVE Many prognostic factors, exceeding 150, for non-small cell lung cancer (NSCLC) are mentioned in the literature. The different statistical weight of the some variables at issue, their heterogeneity and their clinical uselessness is reviewed. STUDY DESIGN AND SETTING Survival analysis of a cohort of NSCLC operated (n = 1730, 1993-1997) was carried out utilizing different statistical approaches: Cox proportional hazard analysis (CPHA), logistic regression (LRA), and recursive partitioning (CART). RESULTS CPHA identified 13 prognostic variables and 11 LRA. Of the 17 possible variables, 10 are coincident. CART provided five different diagnostic groups but only three differentiated survival levels. Parsimonious models were constructed including only T and N cancer staging variables. Areas under the ROC curve of 0.68 and 0.68 were found for CPHA and LGA parsimonious models respectively, and 0.72 and 0.71 for complete models. CONCLUSION Variables with a minimal impact on the respective models and thus with little or scarce predictive clinical repercussion were identified. Differences in the prognostic profile of survival can be caused by the different methodological approaches used. No relevant differences were found between the parsimonious and complete models. Although the amount of information managed is considerable, there continues to be a large predictive gap yet to be explained.

Abstract
OBJECTIVE To evaluate the effect of comorbidity as an independent prognostic factor in lung cancer. METHOD Data on 2991 consecutive cases of lung cancer were collected prospectively from 19 Spanish hospitals between 1993 and 1997 by the Bronchogenic Carcinoma Cooperative Group of the Spanish Society of Pneumology and Thoracic Surgery (GCCB-S). To evaluate the effect of comorbidity on survival, 1121 patients with non-small cell lung cancer (NSCLC) in pathological stage I who underwent complete resection were selected, excluding operative mortality. The presence of specific comorbidities at the time of thoracotomy was registered prospectively. RESULTS Cox regression analysis showed that tumour size (0-2, 2-4, 4-7, >7 cm) (HR 1.45 95% CI 1.08 to 1.95), 1.86 (95% CI 1.38 to 2.51), 2.84 (95% CI 1.98 to 4.08)), the presence of a previous tumour (HR 1.45 (95% CI 1.17 to 1.79)) and age (HR 1.02 (95% CI 1.01 to 1.03)) had a significant prognostic association with survival. This study excluded the presence of visceral pleural involvement or other comorbidities as independent variables. CONCLUSION The presence of a previous tumour is an independent prognostic factor in pathological stage I NSCLC with complete resection, increasing the probability of death by 1.5 times at 5 years. It is independent of other comorbidities, TNM classification and age.
