[PMID: 36608755 DOI: 10.1016/j.athoracsur.2022.11.040] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2022] [Revised: 11/12/2022] [Accepted: 11/21/2022] [Indexed: 01/05/2023]
Abstract
BACKGROUND The prevalence of lymph node (LN) metastasis in small-sized lung cancer varies depending on the tumor size and proportion of ground-glass opacity. We investigated occult LN metastasis and prognosis in patients with small-sized non-small cell lung cancer (NSCLC), mainly focusing on the pure-solid tumor. METHODS We retrospectively reviewed patients with ≤2-cm clinical N0 NSCLC who underwent lung resection with curative intent from 2003 to 2017. Among them we analyzed patients who also underwent adequate complete systematic LN dissection. Pathologic results and disease-free survival of the radiologically mixed ground-glass nodule (mGGN) and pure-solid nodule (PSN) groups were analyzed. RESULTS Of 1329 patients analyzed, 591 had mGGNs and PSNs. As tumor size increased, patients in the mGGN group showed no difference in LN metastasis: ≤1 cm, 2.27%; 1.0 to 1.5 cm, 2.19%; and 1.5 to 2.0 cm, 2.18% (P = .999). However the PSN group showed a significant difference in LN metastasis as the tumor size increased: ≤1 cm, 2.67%; 1.0 to 1.5 cm, 12.46%; and 1.5 to 2.0 cm, 21.31% (P < .001). In the multivariate analysis tumor size was a significant predictor of nodal metastasis in the PSN group but not in the mGGN group. In terms of 5-year disease-free survival, the mGGN group showed a better prognosis than the PSN group (94.4% vs 71.2%, P < .001). CONCLUSIONS We need to conduct a thorough LN dissection during surgery for small-sized NSCLC, especially for pure-solid tumors ≥ 1 cm.

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

Abstract
INTRODUCTION Surgery is the most effective treatment for early-stage lung cancer. This study will propose a personalized plan for mediastinal lymph node dissection in early-stage lung adenocarcinoma to reduce the risk of surgery and improve the quality of life. METHODS This study retrospectively analyzed the patients underwent lobectomy and lymph node dissection in the Department of Thoracic Surgery, Zhongshan Hospital, Fudan University. Clinical stage I lung adenocarcinoma patients with solid component ratio (CTR) between 0.5 and 1 were included. Patients were divided into systematic (S-MLND) and lobe-specific (L-MLND) mediastinal lymph node dissection groups. The days of hospitalization, the presence or absence of complications, the recurrence-free survival rate, and the overall survival rate were calculated to evaluate the postoperative quality and operation risk of the patients. RESULTS 210 patients (138 L-MLND and 72 S-MLND) were included. 2 lymph node metastases appeared in the S-MLND group while none in the L-MLND group (P = .049). No differences were shown in age, tumor site, size, solid component, degree of tumor invasion, and stage. The proportion of patients with severe postoperative cough and the length of hospital stay in the L-MLND group decreased. The 5-year OS of the entire cohort was 98.1%, 98.6% in L-MLND, compared with 97.2% in S-MLND; RFS was 94.8%, 95.7% in L-MLND, compared with 93.0% in S-MLND. CONCLUSION For cIA lung adenocarcinoma, according to the Thin-slice CT within 1 month before the operation, if the main lesion was less than 3 cm and CTR over 0.5, L-MLND is as effective as S-MLND.

Abstract
OBJECTIVE To develop and validate nomograms for preoperative prediction of precision lymph node (LN) dissection in lung cancer. PATIENTS AND METHODS The prediction models of each group LNs (LNx) were developed in a primary cohort that consisted of 1380 patients with clinicopathologically confirmed lung cancer. Clinical characteristics and CT reports were extracted. Patients with LNx dissection were divided into training cohort and testing cohort. Nomograms were built through univariate and multivariate regression analysis in the training cohort and internally verified in the testing cohort. The accuracy of the models was verified by constructing survival analysis in patients without LNx dissection. RESULTS Due to the lack of sufficient patients for LN1, 8, 13, a total of 10 nomograms were constructed in this study, including LN-2 ∼ 7, 9 ∼ 12. According to the nomogram of each group LN, the most common independent risk factors predicting LN status were CT-reported lymphadenectasis, tumor diameter and location, and the others include age, gender, and whether there were multiple nodules, etc. All models showed good discrimination, with the average C-index of 0.738 in the training cohort and 0.707 in the testing cohort. Survival analysis in patients without LNx dissection all showed the high accuracy of each nomogram to predict LN metastasis status and TNM staging. CONCLUSION We constructed nomograms to predict the metastasis status of each group of lymph nodes based on clinical characteristics and CT reports. Surgeons can accurately determine the extent of lymph node dissection in patients with lung cancer based on our nomogram models before surgery.

Abstract
PURPOSE It is essential to evaluate the risk of occult lymph node (LN) disease in early-stage non-small cell lung cancer (NSCLC), especially because delivering stereotactic ablative radiotherapy (SABR) assumes no occult spread. This study was designed to assist clinicians in roughly quantifying this risk for cN0 NSCLC. METHODS The National Cancer Data Base was queried for cN0 cM0 lung squamous cell or adenocarcinoma who underwent surgery and LN dissection without neoadjuvant therapy. Statistics included multivariable logistic regression to evaluate factors associated with pN + disease. RESULTS 109,964 patients were included. For tumors with size ≤1.0, 1.1-2.0, 2.1-3.0, 3.1-4.0, 4.1-5.0, 5.1-6.0, 6.1-7.0, and >7.0 cm, the pN + rate was 4.4, 7.7, 12.9, 18.0, 20.2, 22.5, 24.4, and 26.4%, respectively. When examining patients with more complete LN dissections (defined as removal of at least 10 LNs), the respective values were 6.6, 11.5, 17.6, 25.3, 26.8, 29.7, 30.7, and 31.6%. Moderately-poorly differentiated disease and adenocarcinomas were associated with a higher rate of pN + disease (p < .001 for both). For every cm increase in tumor size, the relative occult nodal risk increased by 10-14% (p < .001). For every elapsed day from initial diagnosis, the relative risk increased by ∼1% (p < .001). Graphs with best-fit lines were created based on tumor size, histology, and differentiation to aid physicians in estimating the pN + risk. CONCLUSIONS This nationwide study can allow clinicians to roughly estimate the rate of occult LN disease in cN0 NSCLC. These data can also assist in guiding enrollment on randomized trials of SABR ± immunotherapy, individualizing follow-up imaging surveillance, and patient counseling to avoid post-diagnosis delays.

Abstract
Early diagnosis in lung cancer is desirable, because surgical resection offers the only hope of cure. In the face of suggestive symptoms, a normal plain chest radiograph does not exclude the diagnosis, and investigation is essential. The various imaging changes seen on computerized tomography and PET scan provide strong suggestive evidence of lung cancer, but proof of diagnosis rests on histologic examination, material that may be obtained by one of the following diagnostic procedures: bronchoscopy, mediastinoscopy, fine needle aspiration biopsy, thoracentesis and pleural biopsy, lymph node biopsy, and exploratory thoracotomy.

Lobe-specific Lymph Node Dissection in Clinical Stage IA Solid-dominant Non-small-cell Lung Cancer: A Propensity Score Matching Study. Clin Lung Cancer 2020; 22:e201-e210.

Abstract
BACKGROUND Lobectomy with systematic lymph node dissection (SND) remains the standard procedure for resectable non-small-cell lung cancer (NSCLC), whereas lobe-specific lymph node dissection (LSND) was reported to have more advantages in perioperative recovery and complication reduction in treating early-stage diseases. Survival outcomes after LSND remains controversial compared with SND. PATIENTS AND METHODS From 2014 to 2017, data of 546 patients with clinical stage IA solid-dominant NSCLC and who underwent curative lobectomies with LSND (n = 100) or SND (n = 446) at our institution were collected. Propensity score matching was conducted to eliminate the biases. Five-year disease-free survival and overall survival were compared between the groups. Perioperative parameters and postoperative complications were also analyzed. RESULTS Lobectomies with LSND or SND were performed in 100 patients and 446 patients, respectively. After matching, there were 100 patients in each group and no significant differences in 5-year overall survival (P = .473) and disease-free survival (P = .789) were found between the groups. Recurrence patterns were also similar (P = .733). Perioperative parameters were similar, whereas the incidence of postoperative complications in the SND group was found to be significantly higher than that in the LSND group (P = .003). CONCLUSIONS Our study demonstrated that LSND has similar efficiency to SND in terms of survival, recurrence, lymph node dissection, and perioperative recovery of patients with clinical stage IA solid-dominant NSCLC, as well as significant advantages in reducing postoperative complications. Therefore, curative lobectomies with LSND may be more suitable and practical for clinical stage IA solid-dominant patients with NSCLC.

Abstract
Lymph node assessment is an essential component of the treatment of lung cancer. Identification of the correct "N" stage is important for staging which in turn determines treatment. Assessment of lymph nodes may be accomplished using imaging with CT scan and PET-CT, invasive techniques such as mediastinoscopy, endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) or endoscopic ultrasound fine needle aspiration (EUS-FNA). Ultimately, regardless of any pre-resection assessment, lymph nodes must be assessed at the time of resection. The question to be addressed in this report is the role of mediastinal lymph node dissection versus lymph node sampling. However, the issues surrounding lymph node assessment in NSCLC are complex, depending on clinical stage, imaging and histology.

Abstract
Background Lymph node metastasis occurs although clinical stage IA is a relatively early stage for patients with non-small cell lung cancer (NSCLC). This study aimed to explore the influencing factors of lymph node metastasis. Methods A total of 200 patients diagnosed with clinical stage IA NSCLC preoperatively from July 2014 to July 2016 were examined. Every patient underwent lobectomy and systematic lymph node dissection. Their clinicopathological characteristics and status of lymph node metastasis are analyzed. Results The rates of both N1 and N2 lymph node metastasis increase with the increase in the tumor diameter. The N1 lymph node metastasis rate is 0%, 2.82%, and 9.52%, while the N2 lymph node metastasis rate is 0%, 4.23%, and 25.40% for pure ground-glass nodules, mixed ground-glass nodules (solid component <50%), and mixed ground-glass nodules (solid component >50%), respectively. The difference is statistically significant (P=0.000). Patients with squamous cell carcinoma have a relatively higher N1 lymph node metastasis rate comparing with patients with adenocarcinoma (P<0.05). Tumors locate in the inner half lobe (close to hilus) are prone to metastasize to lymph nodes (P=0.018). Multiple regression analysis shows that tumor diameter, solid component rate, and tumor location are relevant factors for lymph node metastasis. Conclusions In patients with NSCLC, who have tumors smaller than 1 cm, pure ground-glass nodules, or tumors locate in the lateral half lobe, lymph node metastasis is rare and selective lymphadenectomy is considerable.

Abstract
Lung cancer treatment is a heavy workload for radiation oncologist and that field showed many evolutions over the last two decades. The issue about target volume was raised when treatment delivery became more precise with the development of three-dimensional conformal radiotherapy. Initially based upon surgical series, numerous retrospective and prospective studies aimed to evaluate the risk of elective nodal failure of involved-field radiotherapy compared to standard large field elective nodal irradiation. In every setting, locally advanced non-small cell lung cancer, localized non-small cell lung cancer, localized small cell lung cancer, exclusive chemoradiation or postoperative radiotherapy, most of the studies showed no significant difference between involved-field radiotherapy or elective nodal irradiation with elective nodal failure rate under 5% at 2 years, provided staging had been done with modern imaging and diagnostic techniques (positron emission tomography scan, endoscopy, etc.). Moreover, if reducing irradiated volumes are safe regarding recurrences, involved-field radiotherapy allowed dose escalation while reducing acute and late oesophageal, cardiac and pulmonary toxicities. Consequently, major clinical trials involving radiotherapy initiated in the last two decades and international clinical guidelines recommended omission of elective nodal irradiation in favour of in-field radiotherapy.

Abstract
BACKGROUND Controversy still exists in which subtype of non-small-cell lung cancer [squamous cell carcinoma (SCC) or adenocarcinoma] is more likely to have lymph node (LN) metastasis. The aim of this study is to compare the pattern of LN metastasis in two cohorts of matched patients surgically treated for SCC or adenocarcinoma. METHODS A retrospective analysis of patients undergoing lobectomy or segmentectomy with systematic lymphadenectomy without preoperative treatment for lung SCC or adenocarcinoma was conducted in this study. Data for analysis consisted of age, gender, tumor size, lobe-specific tumor location, tumor location (peripheral or central), and pathologic findings. We conducted the propensity score-matched (PSM) analysis to eliminate potential bias effects of possible confounding factors. RESULTS From January 2015 to December 2016 in our department, we finally included a total of 387 patients (including 63 patients with SCC and 324 patients with adenocarcinoma) for analysis. For the unmatched cohort, there was no sufficient evidence of significantly different number of positive LNs (P = 0.90) and rate of LN metastasis (P = 0.23) between SCC patients and adenocarcinoma patients. However, potential confounding factors, for example gender, tumor size, tumor location, tumor differentiation, and total number of dissected LNs, were significantly different between patients with SCC and those with adenocarcinoma. In the analysis of matched cohort after PSM analysis, those above confounding factors were comparable between the two groups. However, patients with adenocarcinoma had significantly more mean positive LNs (2.2 and 0.7; P = 0.008) and a higher rate of LN metastasis (53% and 29%; P = 0.016) than those with SCC. CONCLUSIONS Lung adenocarcinoma had a higher risk of LN metastasis than SCC, suggesting that different therapeutic modalities may be indicated for the two different subtypes of lung cancer.

Abstract
Background The pathologic stages of lymph nodes usually differ from preoperatively predicted in lung cancers and it is difficult to predict the metastasis of lymph nodes for the patients diagnosed as clinical stage IA non-small cell lung cancers (NSCLC). This study aimed to investigate the patterns of lymph node metastasis and the risk factors predicting lymph node metastasis in the patients with clinical stage IA NSCLCs. Methods All patients diagnosed as clinical stage IA NSCLC from July 2013 to June 2017 in our center were retrospectively reviewed, and a total number of 1,543 patients who underwent anatomical lobectomy with systematic lymph node dissection were enrolled in this study. Multivariate logistic regression analysis was performed to identify the risk factors predicting lymph node metastasis, and Fisher's exact test was used to confirm the lymph node spread mode according to the locations of primary tumors. Results Totally, lymph node metastases presented in 131 patients (8.5%) in this series. Sixty-three patients presented N1 diseases, 17 patients showed only skipped N2 diseases, and 51 patients had simultaneous N1 and N2 positive lymph nodes. No lymph node metastasis was found in the patients with pure ground grass opacity (GGO). When patients were arbitrarily divided into six groups by the longest tumor diameter of ≤0.5, 0.6-1, 1.1-1.5, 1.6-2.0, 2.1-2.5, 2.6-3 cm, the lymph node metastasis rates of each group were 0% (0/20), 1.5% (4/264), 4.7% (20/429), 8.6% (29/336), 13.1% (38/290), 19.6% (40/204), respectively. When the patients with pure GGO were excluded, the lymph node metastasis rates in the patients with partial or total solid tumors were 0% (0/10), 2.4% (4/164), 6.6% (20/303), 11.7% (29/249), 16.0% (38/238) and 23.1% (40/173). The cut off value showed by receiver operating characteristic (ROC) curve for tumor size was 1.95 cm, and the area under the curve (AUC) was measured as 0.681 (P<0.001, 95% CI: 0.630-0.726). Multivariate logistic regression analysis indicated that male patients [odds ratio (OR) =3.34, P=0.012], smoking history (OR =14.12, P<0.001), solid components (OR =3.34, P=0.01), large tumor size (OR =1.9, P<0.001), poor differentiation (OR =2.25, P=0.013), lymphovascular invasion (OR =58.45, P<0.001), visceral pleural invasion (OR =48.37, P<0.001) were significantly associated with lymph node metastasis in clinical stage IA NSCLC. The rate of non-lobe specific lymph node metastasis was 15.8-40.0% when any of the lobe specific lymph nodes was positive, while it was only 0-2.2% when all lobe specific lymph nodes were negative. Conclusions Tumor size, solid components, poor differentiation, lymphovascular invasion, visceral pleural invasion and smoking history were significant factors predicting lymph node metastasis of clinical stage IA NSCLC. Patients with negative lobe-specific lymph node have very low risk of metastasis to the non-lobe specific lymph nodes. Lobe-specific lymph node dissection may become an alternative lymph node dissection mode for clinical stage IA NSCLC, especially for tumors ≤2 cm.

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

Abstract
It is well established that lung tumors induce the formation of lymphatic vessels. However, the molecular mechanisms controlling tumor lymphangiogenesis in lung cancer have not been fully delineated. In the present study, we identify a panel of non-small cell lung cancer (NSCLC) cell lines that induce lymphangiogenesis and use genome-wide mRNA expression to characterize the molecular mechanisms regulating tumor lymphangiogenesis. We show that Calu-1, H1993, HCC461, HCC827, and H2122 NSCLC cell lines form tumors that induce lymphangiogenesis whereas Calu-3, H1155, H1975, and H2073 NSCLC cell lines form tumors that do not induce lymphangiogenesis. By analyzing genome-wide mRNA expression data, we identify a 17-gene expression signature that distinguishes lymphangiogenic from non-lymphangiogenic NSCLC cell lines. Importantly, VEGF-C is the only lymphatic growth factor in this expression signature and is approximately 50-fold higher in the lymphangiogenic group than in the non-lymphangiogenic group. We show that forced expression of VEGF-C by H1975 cells induces lymphangiogenesis and that knockdown of VEGF-C in H1993 cells inhibits lymphangiogenesis. Additionally, we demonstrate that the triple angiokinase inhibitor, nintedanib (small molecule that blocks all FGFRs, PDGFRs, and VEGFRs), suppresses tumor lymphangiogenesis in H1993 tumors. Together, these data suggest that VEGF-C is the dominant driver of tumor lymphangiogenesis in NSCLC and reveal a specific therapy that could potentially block tumor lymphangiogenesis in NSCLC patients.

Dosimetric evaluation of the feasibility of stereotactic body radiotherapy for primary lung cancer with lobe-specific selective elective nodal irradiation.

Abstract
More than 10% of all patients treated with stereotactic body radiotherapy (SBRT) for primary lung cancer develop regional lymph node recurrence. We evaluated the dosimetric feasibility of SBRT with lobe-specific selective elective nodal irradiation (ENI) on dose-volume histograms. A total of 21 patients were treated with SBRT for Stage I primary lung cancer between January 2010 and June 2012 at our institution. The extents of lobe-specific selective ENI fields were determined with reference to prior surgical reports. The ENI fields included lymph node stations (LNS) 3 + 4 + 11 for the right upper lobe tumors, LNS 7 + 11 for the right middle or lower lobe tumors, LNS 5 + 11 for the left upper lobe tumors, and LNS 7 + 11 for the left lower lobe tumors. A composite plan was generated by combining the ENI plan and the SBRT plan and recalculating for biologically equivalent doses of 2 Gy per fraction, using a linear quadratic model. The V20 of the lung, D(1cm3) of the spinal cord, D(1cm3) and D(10cm3) of the esophagus and D(10cm3) of the tracheobronchial wall were evaluated. Of the 21 patients, nine patients (43%) could not fulfill the dose constraints. In all these patients, the distance between the planning target volume (PTV) of ENI (PTVeni) and the PTV of SBRT (PTVsrt) was ≤2.0 cm. Of the three patients who developed regional metastasis, two patients had isolated lymph node failure, and the lymph node metastasis was included within the ENI field. When the distance between the PTVeni and PTVsrt is >2.0 cm, SBRT with selective ENI may therefore dosimetrically feasible.

Abstract
Background: This study analyzed the relation between the tumor size and the lymph node metastasis in adenocarcinoma of the lung with a size of 30 mm or smaller. Methods: Four hundred thirteen patients who had undergone curative resection for lung adenocarcinoma were enrolled. If the tumor presented ground-glass opacities on the preoperative high-resolution computed tomography, both the total size including ground-glass opacities and the solid size alone were measured. To calculate the rates of lymph node metastasis by the tumor size, the tumors were divided into six groups by their sizes: 5 mm or less, 6 to 10 mm, 11 to 15 mm, 16 to 20 mm, 21 to 25 mm, and 26 to 30 mm. Results: The average numbers of dissected lymph nodes and dissected lymph node stations were 17 and 5, respectively. Seventy-five patients (18%) were postoperatively discovered to have positive nodes. The rates of node metastasis in each total size group were 0/1 (0%), 0/29 (0%), 5/77 (7%), 17/121 (14%), 27/101 (27%), and 26/84 (31%), respectively. The rates of node metastasis in each solid size group were 0/37 (0%), 1/53 (2%), 9/88 (10%), 17/104 (16%), 23/78 (30%), and 25/53 (47%), respectively. The area under the curve of receiver operating characteristic curves for the total size was measured as 0.701, and that for the solid size was measured as 0.777. By multivariate analysis, solid size, maximum standardized uptake value, and lymphovascular invasion were independent significant predictive factors. Conclusions: Solid size, maximum standardized uptake value, and lymphovascular invasion were independent predictors for lymph node metastasis of lung adenocarcinoma. The size of the solid component explained the relation between the tumor size and the lymph node metastasis more accurately than that explained by the total tumor size on high-resolution computed tomography.

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.

Is the rate of pneumonectomy higher in right middle lobe lung cancer than in other right-sided locations? Ann Thorac Surg 2013; 97:402-7.

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.

[PMID: 23835164 DOI: 10.1016/j.cllc.2013.02.002] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2012] [Revised: 12/23/2012] [Accepted: 02/12/2013] [Indexed: 12/31/2022]
Abstract
PURPOSE To determine whether the standard uptake value (SUV) of the primary lesion can predict mediastinal lymph node metastasis in clinical stage IA non--small-cell lung cancer (NSCLC). MATERIALS AND METHODS At 5 centers, patients with clinical stage IA NSCLC from February 2004 to August 2010 were analyzed retrospectively. Data from Shandong Cancer Hospital and from the Cancer Hospital Affiliated to Harbin Medical University were used as a testing set, and data from the other 3 institutions were used as the validation set. Final diagnosis was established based on the histopathologic examination. RESULTS Data from 144 patients were collected for the study. The primary results in our study showed that maximal SUV (SUVmax) of primary tumor might be a predictor of lymph node metastasis (χ(2) = 10.424; P = .001) and the best cutoff value was 7.25 (P = .029). For the testing set, lymph node metastasis rates in low-grade group (SUVmax < 7.25) and high-grade group (SUVmax > 7.25) were 5% (2/43) and 36% (9/25) (P = .001) For the total data set, lymph node metastasis rate was 7% (6/93) in low-grade group (SUVmax < 7.25) and 26% (13/51) in high-grade group (SUVmax > 7.25) (χ(2)= 10.424; P = .001). A multivariate analysis revealed that no factors were applied to predict the probability of metastasis. But the analysis showed a weak correlation between SUVmax and nodal status (r = 0.21; P = .011) with bivariate correlation. CONCLUSION Analysis of our data suggested that fluorine-18 fluorodeoxyglucose SUVmax of the primary tumor might be a predictor of lymph node involvement in stage IA NSCLC. The rate of mediastinal lymph node metastasis of patients with a lower fluorine-18 fluorodeoxyglucose positron emission tomography-computed tomography SUVmax might be relatively low, which provides more evidence for clinical procedures of clinical stage IA 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
BACKGROUND The effect of tumor location on long-term survival after lobectomy for stage I non-small-cell lung cancer is unclear. Current data are limited to a retrospective single-institution series. We sought to determine if tumor anatomic location (i.e., the particular lobe that was involved) confers a survival advantage based on population-based data. METHODS Using the Surveillance, Epidemiology and End Results database (1988-2007), we identified patients who underwent lobectomy for pathologic T1/T2 adenocarcinoma or squamous cell carcinomas. Wedge resections, segmentectomies, and pneumonectomies were excluded. We evaluated the association between the particular lobe that was involved, lymph node (LN) yield, and survival using the Kaplan-Meier method. To adjust for potential confounders, we used a Cox proportional hazards regression model. RESULTS We identified 13,650 patients who met our inclusion criteria. There were significant differences in unadjusted overall (P=0.03) and cancer-specific survivals (P=0.03) based on tumor location. However, after adjusting for patient factors, geographic location of treatment, and tumor characteristics, we found that tumor location was not associated with significant differences in survival. We found that male gender, black race, squamous cell histology, increasing grade, and age were independent negative predictors of survival. Higher LN yields were independently associated with improved survival. Although adjusted survival rates were not significantly different, there were significant differences (P<0.0001) in LN yield based on tumor location; right middle lobe had the lowest yield (5.1 nodes), and left upper lobe had the highest yield (eight nodes). CONCLUSIONS LN counts are independent predictors of survival. Although it is associated with significant difference in LN yield, tumor location is not an independent predictor of survival. Age, race, gender, tumor size, histology, and grade appear to be more important prognostic factors. These data suggest that treatment of T1/T2 non-small-cell lung cancer should be dictated by the same oncologic principles, regardless of tumor location.

Abstract
The aim in this study was to define the pattern of lymph node metastasis according to the primary tumor location. In this retrospective cohort study, each of the operable patients diagnosed with lung cancer was grouped by tumor mass location. The International Association for the Study of Lung Cancer nodal chart with stations and zones, established in 2009, was used to define lymph node levels. From 2006 to 2010, 197 patients underwent a lobectomy with systematic nodal resection for primary lung cancer at Chiang Mai University Hospital. There were 123 male and 74 female patients, with ages ranging from 16– 85 years old and an average age of 61.31. Analyses of tumor location, histology type, and nodal metastasis were performed. The locations were the right upper lobe in 63 patients (31.98%), the right middle lobe in 18 patients (9.14%), the right lower lobe in 30 patients (15.23%), the left upper lobe in 55 patients (27.92%), the left lower lobe in 16 patients (8.12%), and mixed lobes (more than one lobe) in 15 patients (7.61%). The mean tumor size was 4.45 cm in diameter (range 1.2–16.5 cm). Adenocarcinoma was the most common histological type, which occurred in 132 cases (67.01%), followed by squamous cell carcinoma in 41 cases (20.81%), bronchiolo alveolar cell carcinoma in nine cases (4.57%), and large cell carcinoma in seven cases (3.55%). Eighteen cases (9.6%) had skip metastasis (mediastinal lymph node metastasis without hilar node metastasis). Adenocarcinoma and intratumoral lymphatic invasion were the predictors of mediastinal lymph node metastases. There were statistically significant differences between a tumor in the right upper lobe and the right lower lobe. However, there were no statistically significant differences between tumors in the other lobes. In conclusion, tumor location is not a precise predictor of the pattern of nodal metastasis. Systematic lymph node dissection is the only way to accurately determine lymph node status. Further studies are required for evaluation and conclusions.

Extent of lymph node resection does not increase perioperative morbidity and mortality after surgery for stage I lung cancer in the elderly. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2012; 38:516-22. [PMID: 22244908 DOI: 10.1016/j.ejso.2011.12.018] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2011] [Revised: 09/25/2011] [Accepted: 12/19/2011] [Indexed: 10/14/2022]
Abstract
BACKGROUND & OBJECTIVES Pathologic evaluation of > 10 lymph nodes (LNs) is considered necessary for accurate lung cancer staging. However, physicians have concerns about increased risk in perioperative mortality (POM) and morbidity with more extensive LN sampling, particularly in the elderly. In this study, we compared the outcomes in elderly patients with stage I non-small cell lung cancer (NSCLC) undergoing extensive (> 10 nodes) and limited (≤ 10 nodes) LN resections. METHODS Using data from the Surveillance, Epidemiology and End Results registry linked to Medicare records, we identified 4975 patients ≥ 65 years of age with stage I NSCLC who underwent a lobectomy between 1992 and 2002. Risk of perioperative morbidity and POM after the evaluation of ≤ 10 vs. >10 LNs was compared among patients after adjusting for propensity scores. RESULTS Multiple regression analysis showed similar POM between the two groups (OR, 1,01; 95% CI, 0,71-1,44). Other postoperative complications were similar across groups except for thromboembolic events, which were more common among patients undergoing resection of > 10 LNs (OR, 1,72; 95% CI, 1,12-2,63). CONCLUSIONS These data suggest that evaluation of > 10 LNs, which allows for more accurate staging, appears to be safe in the elderly patients undergoing lobectomy for stage I NSCLC without compromising postoperative recovery.

Abstract
BACKGROUND AND OBJECTIVES We investigated various tumor markers in patients with surgically treated small cell lung cancer (SCLC) to identify the markers closely correlated to pathological staging and to predict survival by retrospective analyses. METHODS Reviewing database records between 1990 and 2007 revealed 36 patients with SCLC, that were grouped according to clinical and pathological stages. Receiver operating characteristic (ROC) curves were calculated for serum levels of various tumor makers to predict the pathological stage. The cut-off value was calculated from the ROC curve of the significant marker. Survival in patient groups divided by the new cut-off value was calculated. RESULTS Serum levels of various tumor makers were not significantly different between the pathological stage groups, except for serum sialyl Lewis X (SLX). ROC curve of SLX was significantly correlated to pathological stages (P = 0.0136). The calculated SLX cut-off value was 25.1 U/ml, with 80% sensitivity and 70% specificity. Five-year survival of patients selected by this new cut-off was 82.5%, whereas that with the standard cut-off (38.0 U/ml) was 55.9%. CONCLUSIONS Serum SLX values were associated with pathological stage and survival after surgery in SCLC patients.

Abstract
BACKGROUND The goal of this study was to investigate the prognostic factors and patterns of recurrence in patients with resected non-small cell lung cancer (NSCLC) < or = 1 cm in diameter. METHODS We conducted a retrospective review of the clinicopathological characteristics of 71 patients with NSCLC < or = 1 cm in diameter in Taipei Veterans General Hospital between 1982 and 2007. Overall survival and its predictors were analyzed. RESULTS Median follow-up time of the 71 patients was 33.3 months. Complete resection was performed in 68 patients (95.8%) with stage I disease. The 5- and 10-year overall survival rates of patients who underwent complete resections were 81.7% and 44.9%, respectively. There was tumor recurrence in 6 (8.8%) of these 68 patients. Five (9.3%) of 54 patients who underwent standard resection experienced tumor recurrence, but only 1 (7.1%) of 14 patients who received sublobar resection had recurrent disease. The difference was not statistically significant (p = 0.569). Multivariate analysis revealed that sublobar resection (hazard ratio, 5.00; 95% confidence interval, 1.28-20.00; p = 0.020) was a significant predictor for worse overall survival. CONCLUSION Survival in patients with NSCLC pound 1 cm in diameter is satisfactory. Sublobar resection, performed in patients unfit for standard resection, is a poor prognostic factor for overall survival.

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 Although the lower lobe is a large entity that occupies half of the hemithorax, all tumors located within the lower lobe have been treated uniformly regardless of tumor location. The aim of this study was to reveal differences in the metastatic pathway to the mediastinum and in prognosis of N2 disease between lung cancers originating from superior and basal segment of the lower lobe. METHODS Data on 139 patients who underwent pulmonary resection with systematic nodal dissection for pN2 non-small cell lung cancer (NSCLC) originating from the lower lobe between 1980 and 2001 were retrospectively reviewed. Those lower lobe N2 tumors were divided into two groups by origin: 51 were superior segment, and 88 were basal segment. RESULTS The superior segment group showed a significantly higher incidence of superior mediastinal metastasis than the basal segment group (64% vs 36%, p = 0.0012). When superior mediastinal metastasis existed, the basal segment group showed a significantly higher incidence of synchronous subcarinal metastasis than the superior segment group (81% vs 39%, p = 0.0006). Pneumonectomy was required significantly more often in the superior segment group than in the basal segment group (45% vs 17%, p = 0.0003). The basal segment origin tumors with only subcarinal metastasis showed significantly better prognosis than other lower lobe N2 tumors (5-year survival, 43% vs 18%; p = 0.0155). CONCLUSIONS Basal segment tumor metastasizes to the superior mediastinum mostly through the subcarinal node, whereas superior segment tumors often metastasize directly to the superior mediastinum without concomitant metastasis to the subcarinal node. Superior mediastinal dissection will be mandatory for accurate staging of superior segment tumors even when the subcarinal node is negative on frozen section. As for the prognosis among lower lobe N2 tumors, only in cases with basal segment tumor without superior mediastinal metastasis may long-term survival be expected.

Abstract
Mediastinal lymph node status has important prognostic and therapeutic implications for nonsmall cell lung cancer patients. Consequently, an accurate pathologic assessment of mediastinal lymph nodes for metastasis is essential. Despite the significance of nodal assessment, practice patterns among surgeons vary widely. Therefore we reviewed the literature to provide evidence-based recommendations regarding the ideal means and extent of preoperative and intraoperative pathologic mediastinal lymph node staging in non-small cell lung cancer patients. We found that the most sensitive and accurate intraoperative method is a complete mediastinal lymph node dissection. Pathologic evaluation of at least 10 mediastinal lymph node from at least three stations should be performed at the time of surgery.

Abstract
BACKGROUND Factors that predict poor survival or increased risk of recurrence for patients with N1 disease may be dependent on tumor characteristics. METHODS This study was a retrospective review of a prospective database of consecutive patients who had clinical or pathologic N1 non-small cell lung cancer (NSCLC) who underwent preoperative 2-[18F] fluoro-2-deoxy-D-glucose (FDG)-positron emission tomography (PET) scans and complete resection with thoracic lymphadenectomy. RESULTS There were 135 patients (88 men). The 5-year disease-free rate was 55%. Kaplan-Meier analysis showed that poor differentiation (p = 0.036), multiple N1 stations (p = 0.010), and the lack of adjuvant chemotherapy (p = 0.039) were all associated with a shorter 5-year disease-free rate. Multivariate disease-free analysis demonstrated that only multiple stations (p = 0.002) were independently associated with recurrence. The overall 5-year survival was 48%. Univariate analysis showed that multiple nodes within one station (p = 0.016), multiple station involvement (p = 0.041), and lack of adjuvant chemotherapy (p = 0.039) and moderate-to-poor tumor differentiation (p = 0.046) were associated with decreased survival. Multivariate analysis found that multiple stations, multiple nodes, and lack of adjuvant chemotherapy were independent predictors of poor survival. Integrated PET-computed tomography (CT) was significantly more sensitive for staging N1 disease than dedicated FDG-PET (p = 0.032). Neoadjuvant chemotherapy given to 48 nonrandomized patients did not seem to impact disease recurrence or overall 5-year survival rates (p = 0.349). CONCLUSIONS Factors that predict a poor outcome in patients with resected N1 NSCLC are the involvement of multiple N1 stations, multiple N1 nodes, and the lack of adjuvant chemotherapy. Integrated PET-CT is more sensitive for detecting N1 disease then dedicated PET. These data may influence preoperative or postoperative therapy, or both.

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
The use of conformal radiotherapy in lung cancer has considerably evolved with the advent of improved staging technologies and methods of radiation delivery. Patients with limited disease, inoperable for medical reasons, may be treated with conformal radiotherapy alone; patients with more advanced disease are treated with combined chemo-radiotherapy. If local control may be improved by radiotherapy dose escalation according to several studies, toxicity and more particularly pulmonary toxicity seems to be related to radiation volume. Thus the use of elective nodal irradiation is being questioned. Data for early stage (stage I) non-small-cell lung cancer treated with conformal radiotherapy or stereotactic hypofractionated radiotherapy strongly supports the use of smaller fields that do not incorporate elective nodal regions; local control and survival rates approach those of surgical series. In locally advanced non-small cell lung cancer, eliminating elective nodal irradiation allows to maximize tumor dose and minimize normal tissue toxicity in combined modality treatments; results are encouraging. The use of staging modalities such as positron emission tomography and eventually oesophageal ultrasonography is increasing, allowing to encompass the tumor volume with more accuracy. Several studies have confirmed that involved-field irradiation results into a regional nodal rate of less than 10%. Further larger-scale studies would be needed to definitely establish "no elective nodal irradiation" as a standard in non-small cell lung cancer. There are very few data concerning small cell lung cancer.
