Wagner G, Xie R, Donahue J, Wei B. The Relationship Between Nodal Metastases and Primary Location in Stage I Non-Small Cell Lung Cancer. J Surg Res 2024; 302:578-584. [PMID: 39181024 DOI: 10.1016/j.jss.2024.07.102] [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: 08/02/2023] [Revised: 03/25/2024] [Accepted: 07/28/2024] [Indexed: 08/27/2024]
Abstract
INTRODUCTION This study examines the relationship between location of the primary tumor and specific nodal metastases in clinical stage 1 non-small cell lung cancer (NSCLC) patients undergoing lobectomy. METHODS We retrospectively analyzed all lobectomies performed at a single institution, between January 2005 and December 2019, for clinical stage I NSCLC patients. Patients selected for this study were clinically node negative (cN0) by positron emission tomography-computed tomography scan and selectively by endobronchial ultrasound or mediastinoscopy. Cases of postoperative pathologic nodal upstaging were identified among these patients. For each patient upstaged, the specific lymph node stations found to be positive were recorded. Descriptive statistics, chi-squared tests, and Fisher's exact test were utilized to identify independent risk factors for upstaging to specific N1 and N2 lymph node stations. All clinical and pathologic staging information was retrospectively normalized to the International Association for the Study of Lung Cancer 8th Edition TNM Classification. RESULTS The research cohort included 645 patients. The mean age was 68 years (standard deviation ± 9.2), 54% were female, and 88% were White, 11% Black, and 1% other. Twelve percent (n = 75) were upstaged from cN0 to pN1 or pN2 upon final pathologic examination: 41 to pN1 (54.7%) and 34 to pN2 (45.3%). The primary tumor location with the highest rate of nodal upstaging was the left upper lobe (LUL) (12.8%). Tumors in the right middle lobe had the lowest rate of unsuspected nodal metastases (8.8%). Out of all upstaged patients, there were no positive level eight lymph nodes, and only 1 patient with a positive level nine lymph node. Lymph node levels five and six were only positive in LUL primary tumors, a relationship that approached statistical significance (P = 0.0797). No patients with a LUL primary tumor had a positive level seven lymph node. Upstaging at station 12 was significantly associated with the location of the primary tumor, occurring less often in tumors originating in the right upper lobe in comparison to other lobes (P = 0.0288). CONCLUSIONS We identified relationships between the location of a primary tumor and specific nodal upstaging in patients with clinical stage I NSCLC who undergo lobectomy. We found the following: 1) only 1 patient had a positive level eight or nine lymph node out of 645 patients; 2) only LUL primary tumors demonstrated upstaging to level five or six lymph nodes; and 3) right upper lobe tumors were significantly less likely to be associated with a positive level 12 lymph node.

Computed tomography characteristics of cN0 primary non-small cell lung cancer predict occult lymph node metastasis. Eur Radiol 2024:10.1007/s00330-024-10835-z. [PMID: 38850308 DOI: 10.1007/s00330-024-10835-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2023] [Revised: 04/23/2024] [Accepted: 05/10/2024] [Indexed: 06/10/2024]
Abstract
RATIONALE Occult lymph node metastasis (OLNM) is frequently found in patients with resectable non-small cell lung cancer (NSCLC), despite using diagnostic methods recommended by guidelines. OBJECTIVES To evaluate the risk of OLNM in NSCLC patients using the radiologic characteristics of the primary tumor on computed tomography (CT). METHODS We retrospectively reviewed clinicopathologic features of 2042 clinical T1-4N0 NSCLC patients undergoing curative intent pulmonary resection. Unique radiological features (i.e., air-bronchogram throughout the whole tumor, heterogeneous ground-glass opacity (GGO), mainly cystic appearance, endobronchial location), percentage of solid portion, and shape of tumor margin were analyzed via a stepwise approach. We used multivariable logistic regression to assess the relationship between OLNM and tumor characteristics. RESULTS Compared with the other unique features, endobronchial tumors were associated with the highest risk of OLNM (OR = 3.9, 95% confidence interval (CI) = 2.29-6.62), and heterogeneous GGO and mainly cystic tumors were associated with a low risk of OLNM. For tumors without unique features, the percentage of the solid portion was measured, and solid tumors were associated with OLNM (OR = 2.49, 95% CI = 1.86-3.35). Among part-solid tumors with solid proportion > 50%, spiculated margin, and peri-tumoral GGO were associated with OLNM. CONCLUSIONS The risk of OLNM could be assessed using radiologic characteristics on CT. This could allow us to adequately select optimal candidates for invasive nodal staging procedures (INSPs) and complete systematic lymph node dissection. CLINICAL RELEVANCE STATEMENT These data may be helpful for clinicians to select appropriate candidates for INSPs and complete surgical systematic lymph node dissection in NSCLC patients. KEY POINTS Lymph node metastasis status plays a key role in both prognostication and treatment planning. Solid tumors, particularly endobronchial tumors, were associated with occult lymph node metastasis (OLNM). The risk of OLNM can be assessed using radiologic characteristics acquired from CT images.

J Surg Res 2024; 296:674-680. [PMID: 38359682 DOI: 10.1016/j.jss.2024.01.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Revised: 01/08/2024] [Accepted: 01/17/2024] [Indexed: 02/17/2024]
Abstract
INTRODUCTION Minimally invasive approaches to lung resection have become widely acceptable and more recently, segmentectomy has demonstrated equivalent oncologic outcomes when compared to lobectomy for early-stage non-small cell lung cancer (NSCLC). However, studies comparing outcomes following segmentectomy by different surgical approaches are lacking. Our objective was to investigate the outcomes of patients undergoing robotic, video-assisted thoracoscopic surgery (VATS), or open segmentectomy for NSCLC using the National Cancer Database. METHODS NSCLC patients with clinical stage I who underwent segmentectomy from 2010 to 2016 were identified. After propensity-score matching (1:4:1), multivariate logistic regression analyses were performed to determine predictors of 30-d readmissions, 90-d mortality, and overall survival. RESULTS 22,792 patients met study inclusion. After matching, approaches included robotic (n = 2493; 17%), VATS (n = 9972; 66%), and open (n = 2493; 17%). An open approach was associated with higher 30-d readmissions (7% open versus 5.5% VATS versus 5.6% robot, P = 0.033) and 90-d mortality (4.4% open versus 2.2% VATS versus 2.5% robot, P < 0.001). A robotic approach was associated with improved 5-y survival (50% open versus 58% VATS versus 63% robot, P < 0.001). CONCLUSIONS For patients with clinical stage I NSCLC undergoing segmentectomy, compared to the open approach, a VATS approach was associated with lower 30-d readmission and 90-d mortality. A robotic approach was associated with improved 5-y survival compared to open and VATS approaches when matched. Additional studies are necessary to determine if unrecognized covariates contribute to these differences.

Ann Thorac Surg 2023; 116:222-229. [PMID: 36223806 DOI: 10.1016/j.athoracsur.2022.09.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Revised: 08/22/2022] [Accepted: 09/03/2022] [Indexed: 11/01/2022]
Abstract
BACKGROUND The objective of this study is to evaluate the trends of and outcomes associated with the use of minimally invasive lobectomy for stage I and II non-small cell lung cancer (NSCLC) in the United States. METHODS The use of and outcomes associated with open and minimally invasive lobectomy for clinical stage I and stage II NSCLC from 2010 to 2017 in the National Cancer Database were assessed by multivariable logistic regression and propensity score matching. RESULTS From 2010 to 2017, use of minimally invasive lobectomies increased for stage I NSCLC (multivariable-adjusted odds ratio [aOR] 4.52; 95% CI, 3.95-5.18; P < .001) and stage II NSCLC (aOR 4.38; 95% CI, 3.38-5.68; P < .001). In 2015, for the first time, more lobectomies for stage I NSCLC were performed by minimally invasive techniques (52.2%, n = 5647) than by thoracotomy (47.8%, n = 5164); and in 2017, more lobectomies for stage II NSCLC were performed by minimally invasive techniques (54.7%, n = 1620) than by thoracotomy (45.3%, n = 1,342). From 2010 to 2017, the conversion rates from minimally invasive to open lobectomy for stage I NSCLC decreased from 19.6% (n = 466) to 7.2% (n = 521; aOR 0.32; 95% CI, 0.23-0.43; P < .001). Similarly, from 2010 to 2017, the conversion rates from minimally invasive to open lobectomy for stage II NSCLC decreased from 20% (n = 114) to 11.5% (n = 186; aOR 0.39; 95% CI, 0.21-0.72; P = .002). CONCLUSIONS In the United States, for stage I and stage II NSCLC from 2010 to 2017, the use of minimally invasive lobectomy significantly increased while the conversion rate significantly decreased. By 2017, the minimally invasive approach had become the predominant approach for both stage I and stage II NSCLC.

Preoperative PET-SUVmax and volume based PET parameters of the primary tumor fail to predict nodal upstaging in early-stage lung cancer. Lung Cancer 2023; 176:82-88. [PMID: 36623341 DOI: 10.1016/j.lungcan.2022.12.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Revised: 12/17/2022] [Accepted: 12/23/2022] [Indexed: 12/31/2022]
Abstract
OBJECTIVES Accurate nodal staging is of utmost importance in patients with lung cancer. FDG-PET/CT imaging is now part of the routine staging. Despite thorough preoperative staging nodal upstaging still occurs in early-stage lung cancer. However, the predictive value of preoperative PET metrics of the primary tumor on nodal upstaging remains to be unexplored. Our aim was to assess the association of these preoperative PET-parameters with nodal upstaging in histologically confirmed lung adenocarcinoma and squamous cell carcinoma. METHODS From January 2016 to November 2018, 500 patients with pT1-T2/cN0 lung cancer received an anatomical resection with curative intent. 171 patients with adenocarcinoma and squamous cell carcinoma and available PET-CTs were retrospectively included. We analyzed the the association of nodal upstaging with preoperative PET-SUVmax and metabolic PET metrics including total lesion glycolysis (TLG) and metabolic tumor volume (MTV) with different defined thresholds. RESULTS High values of preoperative PET-SUVmax of the primary tumor were associated with squamous cell carcinoma (p < 0.0001) and with larger tumors (p < 0.0001). Increased preoperative C-reactive protein levels (<1mg/dL) correlated significantly with high preoperative PET-SUVmax values (p < 0.0001). No significant relationship between PET-SUVmax and lactate dehydrogenase activity (p = 0.6818), white blood cell count (p = 0.7681), gender (p = 0.1115) or age (p = 0.9284) was observed. Nodal upstaging rate was 14.0 % with 8.8 % N1 and 5.3 % N2 upstaging. Tumor size (p = 0.0468) and number of removed lymph nodes (p = 0.0461) were significant predictors of nodal upstaging but no significant association was found with histology or PET parameters. Of note, increased MTV - regardless of the threshold - tended to associate with nodal upstaging. CONCLUSION Early-stage lung cancer patients with squamous histology and T2 tumors presented increased preoperative PET-SUVmax values. Nevertheless, beyond tumor size and number of removed lymph nodes neither SUVmax nor metabolic PET parameters MTV and TLG were significant predictors of nodal upstaging.

Abstract
Peripheral pulmonary lesions (PPLs) are frequent incidental findings in subjects when performing chest radiographs or chest computed tomography (CT) scans. When a PPL is identified, it is necessary to proceed with a risk stratification based on the patient profile and the characteristics found on chest CT. In order to proceed with a diagnostic procedure, the first-line examination is often a bronchoscopy with tissue sampling. Many guidance technologies have recently been developed to facilitate PPLs sampling. Through bronchoscopy, it is currently possible to ascertain the PPL's benign or malignant nature, delaying the therapy's second phase with radical, supportive, or palliative intent. In this review, we describe all the new tools available: from the innovation of bronchoscopic instrumentation (e.g., ultrathin bronchoscopy and robotic bronchoscopy) to the advances in navigation technology (e.g., radial-probe endobronchial ultrasound, virtual navigation, electromagnetic navigation, shape-sensing navigation, cone-beam computed tomography). In addition, we summarize all the PPLs ablation techniques currently under experimentation. Interventional pulmonology may be a discipline aiming at adopting increasingly innovative and disruptive technologies.

Perioperative and Oncological Outcomes of Robotic-Assisted, Video-Assisted Thoracoscopic and Open Lobectomy for Patients with N1-Metastatic Non-Small Cell Lung Cancer: A Propensity Score-Matched Study. Cancers (Basel) 2022; 14:cancers14215249. [PMID: 36358668 PMCID: PMC9655678 DOI: 10.3390/cancers14215249] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 10/21/2022] [Accepted: 10/24/2022] [Indexed: 11/17/2022] Open
Abstract
(1) Background: Despite the fact that robotic-assisted thoracoscopic lobectomy (RATL) has been prevalently applied for early stage non-small cell lung cancer (NSCLC), its superiorities are still to be fully revealed for patients with metastatic N1 lymph nodes (LNs). We aim to evaluate the advantages of RATL for N1 NSCLC. (2) Methods: This retrospective study identified consecutive pathological N1 NSCLC patients undergoing RATL, video-assisted thoracoscopic lobectomy (VATL), or open lobectomy (OL) in Shanghai Chest Hospital between 2014 and 2020. Further, perioperative and oncological outcomes were investigated. (3) Results: A total of 855 cases (70 RATL, 435 VATL, and 350 OL) were included. Propensity score matching resulted in 70, 140, and 140 cases in the RATL, VATL, and OL groups, respectively. RATL led to (1) the shortest surgical time (p = 0.005) and lowest intraoperative blood loss (p < 0.001); (2) the shortest ICU (p < 0.001) and postsurgical hospital (p < 0.001) stays as well as chest tube duration (p < 0.001); and (3) the lowest morbidities of postsurgical complications (p = 0.016). Moreover, RATL dissected more N1 (p = 0.027), more N1 + N2 (p = 0.027) LNs, and led to a higher upstaging incidence rate (p < 0.050) than VATL. Finally, RATL achieved a comparable 5-year disease-free and overall survival in relation to VATL and OL. (4) Conclusions: RATL led to the most optimal perioperative outcomes among the three surgical approaches and showed superiority in assessing N1 and total LNs over VATL, though it did achieve comparable oncological outcomes in relation to VATL and OL for N1 NSCLC patients.

Postoperative Long-Term Outcomes and Independent Risk Factors of Non-Small-Cell Lung Cancer Patients With Propofol versus Sevoflurane Anesthesia: A Retrospective Cohort Study. Front Pharmacol 2022; 13:945868. [PMID: 35935845 PMCID: PMC9354745 DOI: 10.3389/fphar.2022.945868] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Accepted: 06/22/2022] [Indexed: 11/13/2022] Open
Abstract
Background: Existing studies have shown that the relationship between anesthetic agents and non-small-cell lung cancer (NSCLC) prognosis remains controversial. Therefore, this retrospective cohort study was designed to investigate the effects of propofol or sevoflurane anesthesia on the long-term oncologic outcomes of NSCLC patients.Methods: We identified 1,778 eligible patients (propofol-based total intravenous anesthesia (TIVA) group, n = 686; sevoflurane-based inhalation anesthesia (INHA) group, n = 1,092) out of 2,388 patients undergoing elective NSCLC surgery from June 2013 to June 2016 in the Harbin Medical University Cancer Hospital. The primary endpoints were five-year overall survival and recurrence-free survival. The secondary endpoints were independent risk factors of cancer recurrence or all-cause mortality. The data were analyzed with propensity score matching, Kaplan–Meier survival, and Cox multivariate analyses as appropriate.Results: After propensity score matching, there were 672 patients in each group. The median follow-up period was 69 months (interquartile range: 68–70 months) for all patients. Five-year overall survival was 75.7% (95% confidence interval (CI) 72.4–79.1) in the TIVA group and 71.8% (68.4–75.4) in the INHA group (p = 0.160) (hazard ratio (HR), 0.86; 95% CI, 0.70–1.06; p = 0.158), and five-year recurrence-free survival was 68.5% (65.0–72.2) and 62.7% (59.1–66.5 (p = 0.108) (HR, 0.90; 95% CI, 0.75–1.08; p = 0.253), respectively. Subgroup analyses showed there were no significant difference in the overall survival or recurrence-free survival between the two groups in each TNM stage of NSCLC. The independent risk factors included age ≥60 years, male, blood transfusion, segmental/wedge resection and pneumonectomy, thoracotomy, postoperative complications, lung adenocarcinoma, TNM stages, high CEA and CYFRA211 levels, and postoperative radiotherapy.Conclusions: Our data indicated no difference between the propofol-based TIVA and sevoflurane-based INHA in terms of five-year overall survival and recurrence-free survival after NSCLC surgery.

Abstract
Background Accurate evaluation of lymph node (LN) status is critical for determining the treatment options in patients with non-small cell lung cancer (NSCLC). This study aimed to develop and validate a 18F-FDG PET-based radiomic model for the identification of metastatic LNs from the hypermetabolic mediastinal–hilar LNs in NSCLC. Methods We retrospectively reviewed 259 patients with hypermetabolic LNs who underwent pretreatment 18F-FDG PET/CT and were pathologically confirmed as NSCLC from two centers. Two hundred twenty-eight LNs were allocated to a training cohort (LN = 159) and an internal validation cohort (LN = 69) from one center (7:3 ratio), and 60 LNs were enrolled to an external validation cohort from the other. Radiomic features were extracted from LNs of PET images. A PET radiomics signature was constructed by multivariable logistic regression after using the least absolute shrinkage and selection operator (LASSO) method with 10-fold cross-validation. The PET radiomics signature (model 1) and independent predictors from CT image features and clinical data (model 2) were incorporated into a combined model (model 3). A nomogram was plotted for the complex model, and the performance of the nomogram was assessed by its discrimination, calibration, and clinical usefulness. Results The area under the curve (AUC) values of model 1 were 0.820, 0.785, and 0.808 in the training, internal, and external validation cohorts, respectively, showing good diagnostic efficacy for lymph node metastasis (LNM). Furthermore, model 2 was able to discriminate metastatic LNs in the training (AUC 0.780), internal (AUC 0.794), and external validation cohorts (AUC 0.802), respectively. Model 3 showed optimal diagnostic performance among the three cohorts, with an AUC of 0.874, 0.845, and 0.841, respectively. The nomogram based on the model 3 showed good discrimination and calibration. Conclusions Our study revealed that PET radiomics signature, especially when integrated with CT imaging features, showed the ability to identify true and false positives of mediastinal–hilar LNM detected by PET/CT in patients with NSCLC, which would help clinicians to make individual treatment decisions.

JOURNAL OF RADIATION RESEARCH 2021; 62:884-893.

Abstract
To the best of our knowledge there have been no randomized controlled trials comparing lobectomy-a standard treatment for patients with early-stage non-small cell lung cancer (NSCLC)-and particle beam therapy (PBT), the best performing existing radiotherapy. We conducted a virtual randomized trial in medically operable patients with stage IA NSCLC to compare lobectomy and PBT effectiveness. A Markov model was developed to predict life expectancy after lobectomy and PBT in a cohort of patients with stage IA NSCLC. Ten thousand virtual patients were randomly assigned to each group. Sensitivity analyses were performed as model variables and scenarios changed to determine which treatment strategy was best for improving life expectancy. All estimated model parameters were determined using variables extracted from a systematic literature review of previously published articles. The preferred strategy differed depending on patient age. In young patients, lobectomy showed better life expectancy than that of PBT. The difference in life expectancy between lobectomy and PBT was statistically insignificant in older patients. Our model predicted lobectomy as the preferred strategy when operative mortality was under 5%. However, the preferred strategy changed to PBT if operative mortality post lobectomy was over 5%. For medically operable patients with stage IA NSCLC, our Markov model revealed the preferred strategy of lobectomy or PBT regarding operative mortality changed with varying age and comorbidity. Until randomized controlled trial results become available, we hope the current results will provide a rationale background for clinicians to decide treatment modalities for patients with stage IA NSCLC.

Abstract
Background Accurately predicting the risk level for a lymph node metastasis is critical in the treatment of non-small cell lung cancer (NSCLC). This study aimed to construct a novel nomogram to identify patients with a risk of lymph node metastasis in T1–2 NSCLC based on positron emission tomography/computed tomography (PET/CT) and clinical characteristics. Methods From January 2011 to November 2017, the records of 318 consecutive patients who had undergone PET/CT examination within 30 days before surgical resection for clinical T1–2 NSCLC were retrospectively reviewed. A nomogram to predict the risk of lymph node metastasis was constructed. The model was confirmed using bootstrap resampling, and an independent validation cohort contained 156 patients from June 2017 to February 2020 at another institution. Results Six factors [age, tumor location, histology, the lymph node maximum standardized uptake value (SUVmax), the tumor SUVmax and the carcinoembryonic antigen (CEA) value] were identified and entered into the nomogram. The nomogram developed based on the analysis showed robust discrimination, with an area under the receiver operating characteristic curve of 0.858 in the primary cohort and 0.749 in the validation cohort. The calibration curve for the probability of lymph node metastasis showed excellent concordance between the predicted and actual results. Decision curve analysis suggested that the nomogram was clinically useful. Conclusions We set up and validated a novel and effective nomogram that can predict the risk of lymph node metastasis for individual patients with T1–2 NSCLC. This model may help clinicians to make treatment recommendations for individuals.

Outcomes of nodal upstaging comparing video-assisted thoracoscopic surgery versus open thoracotomy for lung cancer. Lung Cancer 2020; 152:78-85. [PMID: 33360439 DOI: 10.1016/j.lungcan.2020.12.017] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Revised: 12/08/2020] [Accepted: 12/14/2020] [Indexed: 11/21/2022]
Abstract
OBJECTIVES In early stage non-small cell lung cancer, the optimal surgical approach for lymph node dissection remains controversial. Without a uniform standard for the quality of lymph node dissection, outcomes of nodal upstaging comparing video-assisted thoracoscopic surgery (VATS) versus open thoracotomy (OPEN) also remain controversial. Thus, we compared the clinical outcomes of nodal upstaging between each approach. MATERIALS AND METHODS We retrospectively evaluated 1319 surgically resected lung cancer cases between 2008 and 2017 at our institute. Moreover, 348 VATS and 348 OPEN cases were extracted using propensity score matching. We investigated the frequency, prognosis, and post-recurrence course of nodal upstaging between each approach. RESULTS A total of 193 nodal upstaging cases were identified. Nodal upstaging was more frequent in the OPEN group (24 %) than the VATS group (9%) (p < 0.001). However, multivariable analysis revealed the surgical approach was not significantly associated with nodal upstaging (OPEN: odds ratio, 1.3; 95 % confidence interval, 0.93-2.02; p = 0.108) and, after matching, nodal upstaging with each approach were of equivalent frequency (p = 0.752). The median follow-up period was 5.0 years. Nodal upstaging was an independent prognostic factor for worse overall survival, cancer-specific survival, and recurrence-free survival in multivariable analyses (all p < 0.001). Of all cases, 222 recurred after surgery. There were no significant differences in recurrence patterns and initial recurrence sites depending on surgical approach. The 5-year post-recurrence survival rate was 52 % after VATS and 30 % after OPEN; however, this difference was not statistically significant (p = 0.052). Moreover, post-recurrence survival rate was not significantly different between the VATS and OPEN groups (pN0: p = 0.268, pN1: p = 0.437, and pN2: p = 0.144). CONCLUSION Outcomes of nodal upstaging between VATS and OPEN were found to be equivalent. The difference in the frequency of nodal upstaging was not due to inferior quality of lymph node dissection with VATS; rather, that difference resulted from selection bias.

Completeness of lymph node dissection in patients undergoing minimally invasive- or open surgery for non-small cell lung cancer: A nationwide study. Eur J Surg Oncol 2020; 47:1784-1790. [PMID: 33223414 DOI: 10.1016/j.ejso.2020.11.008] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Revised: 10/23/2020] [Accepted: 11/08/2020] [Indexed: 01/20/2023] Open
Abstract
OBJECTIVE In patients with NSCLC, lymph node metastases are an important prognostic factor. Despite an accurate pre-operative work up, for optimal staging an intrapulmonary- and mediastinal lymph node dissection (LND) as part of the operation is mandatory. The aim of this study is to assess the completeness of LND in patients undergoing an intended curative resection for NSCLC in the Netherlands and to compare performance between open surgery and minimally invasive surgery (MIS). MATERIALS AND METHODS The intraoperative LND was evaluated in 7460 patients who had undergone a lobectomy for clinically staged N0-1 NSCLC (2013-2018). The LND was considered complete, when three mediastinal (N2) lymph node stations, including station 7, were sampled or dissected, in addition to the lymph nodes from station 10 and 11. A comparison was made between open surgery and MIS. RESULTS Of 5154 patients, who had MIS, a sufficient intrapulmonary LND was performed in 47.9% and a sufficient mediastinal LND in 58.6%. A complete LND was performed in 31.6%. For 2306 patients who had an open resection, these numbers were 45.0%, 59.0%, and 30.6%, respectively. The overall between-hospital variation in a complete LND ranged between 0 and 72.5%. CONCLUSION In the Netherlands, a complete LND of both intrapulmonary- and mediastinal lymph nodes is performed only in a minority of patients with clinically staged N0-1 NSCLC, with substantial between-hospital variation. No differences were seen between open surgery and MIS. Because of poor performance, completeness of lymph node dissection will be recorded as a mandatory performance indicator in our national audit, to improve the quality of resection.

Abstract
Advancements in imaging and radiotherapy (RT) techniques have allowed for remarkably precise delivery of high radiation dose per treatment fraction to intrathoracic targets. As a non-invasive therapeutic modality (compared to surgery), stereotactic body radiotherapy (SBRT) is an attractive option for patients with early-stage non-small cell lung cancers and oligometastases, especially for older patients with significant comorbidities and pre-existing pulmonary dysfunction. However, the outcomes and side effect profile of SBRT are highly dependent on tumor location, especially if the tumor is located centrally (within 2 cm of the proximal bronchial tree (PBT)] or ultracentrally (touching or within 1 cm of the mediastinum, esophagus, and PBT). In this focused review, we will examine the contemporary practice and principles of using hypofractionated RT or SBRT for central and ultracentral thoracic tumors. We will identify future directions on how this practice may be incorporated into the increasingly complicated modern paradigm of lung cancer treatments which now include immunotherapy along with proton beam radiotherapy.

Abstract
BACKGROUND This retrospective study investigated the prognosis of patients with pathological N1 (pN1) nonsmall cell lung cancer (NSCLC). METHODS We included patients with pN1 NSCLC who underwent lobectomy or pneumonectomy with mediastinal lymph node dissection and achieved complete resection (R0) between January 2000 and December 2012. Patients who received neoadjuvant therapy were excluded. RESULTS A total of 249 patients were included. The mean age was 63.2 years, and 172 patients were males. Of the 249 patients, 200, 20, and 29 underwent lobectomy, bilobectomy, and pneumonectomy, respectively. The median observation period was 5.5 years. The 5-year overall survival (OS) rate was 64.6% (95% confidence interval: 58.3-70.4). Five-year OS rates were 79.8% for positive lymph nodes at station 13 or 14 (n = 57), 59.6% at station 12 (n = 72), 62.7% at station 11 (n = 69), and 56.9% at station 10 (n = 51) (log-rank test; p = 0.016); furthermore, the 5-year OS rate was 75.2% for patients with positive lymph nodes at a single station (n = 160) and 45.4% for patients with positive lymph nodes at multiple stations (n = 89) (log-rank test; p < 0.001). Five-year cumulative incidences of recurrence were equivalent between patients who received adjuvant chemotherapy and patients who did not (45.9 vs. 55.1%; Gray's test; p = 0.366). Distant recurrence was the most frequent mode of recurrence in both groups (70.8 and 67.3%). CONCLUSION The locations and the number of stations of the positive lymph nodes were identified as prognostic factors in patients with pN1 NSCLC. The primary mode of recurrence was distant recurrence irrespective of postoperative adjuvant chemotherapy.

Abstract
BACKGROUND Guidelines recommend invasive mediastinal staging for patients with non-small cell lung cancer and a "central" tumor. However, there is no consensus definition for central location. As such, the decision to perform invasive staging largely remains on an empirical foundation. RESEARCH QUESTION Should patients with peripheral T1 lung tumors undergo invasive mediastinal staging? STUDY DESIGN AND METHODS All participants with a screen-detected cancer with a solid component between 8 and 30 mm were identified from the National Lung Screening Trial. After translation of CT data, cancer location was identified and the X, Y, Z coordinates were determined as well as distance from the main carina. A multivariable logistic regression model was constructed to evaluate for predictors associated with lymph node metastasis. RESULTS Three hundred thirty-two participants were identified, of which 69 had lymph node involvement (20.8%). Of those with lymph node metastasis, 39.1% were N2. There was no difference in rate of lymph node metastasis based on tumor size (OR, 1.03; P = .248). There was also no statistical difference in rate of lymph node metastasis based on location, either by distance from the carina (OR, 0.99; P = .156) or tumor coordinates (X: P = .180; Y: P = .311; Z: P = .292). When adjusted for age, sex, histology, and smoking history, there was no change in the magnitude of the risk, and tests of significance were not altered. INTERPRETATION Our data indicate a high rate of N2 metastasis among T1 tumors and no significant relationship between tumor diameter or location. This suggests that patients with small, peripheral lung cancers may benefit from invasive mediastinal staging.

Abstract
OBJECTIVES Large retrospective series have indicated lower rates of cN0 to pN1 nodal upstaging after video-assisted thoracic surgery (VATS) compared with open resections for Stage I non-small-cell lung cancer (NSCLC). The objective of our multicentre study was to investigate whether the presumed lower rate of N1 upstaging after VATS disappears after correction for central tumour location in a multivariable analysis. METHODS Consecutive patients operated for PET-CT based clinical Stage I NSCLC were selected from prospectively managed surgical databases in 11 European centres. Central tumour location was defined as contact with bronchovascular structures on computer tomography and/or visibility on standard bronchoscopy. RESULTS Eight hundred and ninety-five patients underwent pulmonary resection by VATS (n = 699, 9% conversions) or an open technique (n = 196) in 2014. Incidence of nodal pN1 and pN2 upstaging was 8% and 7% after VATS and 15% and 6% after open surgery, respectively. pN1 was found in 27% of patients with central tumours. Less central tumours were operated on by VATS compared with the open technique (12% vs 28%, P < 0.001). Logistic regression analysis showed that only tumour location had a significant impact on N1 upstaging (OR 6.2, confidence interval 3.6-10.8; P < 0.001) and that the effect of surgical technique (VATS versus open surgery) was no longer significant when accounting for tumour location. CONCLUSIONS A quarter of patients with central clinical Stage I NSCLC was upstaged to pN1 at resection. Central tumour location was the only independent factor associated with N1 upstaging, undermining the evidence for lower N1 upstaging after VATS resections. Studies investigating N1 upstaging after VATS compared with open surgery should be interpreted with caution due to possible selection bias, i.e. relatively more central tumours in the open group with a higher chance of N1 upstaging.

Abstract
RATIONALE Video-assisted thoracoscopic surgery (VATS) and open lobectomy are both standard of care for the treatment of early-stage non-small cell lung cancer (NSCLC) because of equivalent long-term survival. OBJECTIVES To evaluate whether the improved perioperative outcomes associated with VATS lobectomy are explained by surgeon characteristics, including case volume and specialty training. METHODS We analyzed the Surveillance, Epidemiology, and End Results-Medicare-linked registry to identify stage I-II NSCLC in patients above 65 years of age. We used a propensity score model to adjust for differences in patient characteristics undergoing VATS versus open lobectomy. Perioperative complications, extended length of stay, and perioperative mortality among patients were compared after adjustment for surgeon's volume and specialty using linear mixed models. We compared survival using a Cox model with robust standard errors. RESULTS We identified 9,508 patients in the registry who underwent lobectomy for early-stage NSCLC. VATS lobectomies were more commonly performed by high-volume surgeons (P < 0.001) and thoracic surgeons (P = 0.01). VATS lobectomy was associated with decreased adjusted odds of cardiovascular complications (odds ratio [OR] = 0.65; 95% confidence interval [CI] = 0.47-0.90), thromboembolic complications (OR = 0.47; 95% CI = 0.38-0.58), extrapulmonary infections (OR = 0.75; 95% CI = 0.61-0.94), extended length of stay (OR = 0.47; 95% CI = 0.40-0.56), and perioperative mortality (OR = 0.33; 95% CI = 0.23-0.48) even after controlling for differences in surgeon volume and specialty. Long-term survival was equivalent for VATS and open lobectomy (hazard ratio = 0.95; 95% CI = 0.85-1.08) after controlling for patient and tumor characteristics, surgeon volume, and specialization. CONCLUSIONS VATS lobectomy for NSCLC is associated with better postoperative outcomes, but similar long-term survival, compared with open lobectomy among older adults, even after controlling for surgeon experience.

Abstract
Purpose The prognostic value of tumor location in pulmonary adenocarcinoma (ADC) is controversial. We compared the prognosis and relevant data between central-type ADC (CT-ADC) and peripheral-type ADC (PT-ADC) in order to identify the reasons for the different outcomes between them and to improve the treatment strategy and prognosis of these two types. Patients and methods Data of 256 patients with pathologically diagnosed ADC were retrospectively reviewed. The prognostic factors for disease-free survival (DFS), progression-free survival (PFS), and overall survival (OS) were analyzed using univariate and multivariate analyses. Results A total of 124 and 132 patients had CT-ADC and PT-ADC, respectively. CT-ADC was associated with an earlier age, poorer Karnofsky Performance Status (KPS), higher rates of advanced stage, bone metastasis, contralateral pulmonary metastasis, and pleural effusion. Besides, CT-ADC showed a trend toward lower rate of EGFR mutation. Patients with CT-ADC had a significantly shorter PFS/DFS and OS than did those with PT-ADC. Multivariate analysis revealed that advanced stage, central-type location, EGFR wild-type, no surgery, presence of COPD, and interstitial lung disease (ILD) were independent poor prognostic factors for OS. The rate of surgery was significantly lower in patients with CT-ADC. Among patients with ILD or COPD, OS is shorter in patients with central- than peripheral-type tumors. Conclusion CT-ADC is associated with poorer survival than PT-ADC and the lower rate of surgery in patients with CT-ADC is an important reason for this. Tumor location of pulmonary ADC plays a critical role in predicting prognosis and choosing therapeutic strategies.

Long-term outcomes of video-assisted thoracoscopic surgery lobectomy vs. thoracotomy lobectomy for stage IA non-small cell lung cancer. Surg Today 2018; 49:369-377. [PMID: 30511319 DOI: 10.1007/s00595-018-1746-4] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2018] [Accepted: 11/11/2018] [Indexed: 10/27/2022]
Abstract
OBJECTIVES Video-assisted thoracoscopic surgery (VATS) lobectomy is performed widely for patients with clinical stage I non-small cell lung cancer (NSCLC) because of its superior short-term outcomes to those of thoracotomy lobectomy. However, the long-term outcomes of VATS lobectomy vs. thoracotomy lobectomy remain controversial. METHODS We reviewed the clinical data of 202 consecutive patients who underwent lobectomy for clinical stage IA NSCLC at our institution between January, 2008 and December, 2013. Stage IA NSCLC was confirmed pathologically in 162 of these patients, 60 of whom underwent VATS lobectomy and 102 of whom underwent thoracotomy lobectomy. We compared the perioperative clinical factors and outcomes of these two groups, using a propensity score-matched analysis. RESULTS In an analysis of 58 matched cases, the VATS group showed less blood loss, a shorter duration of chest tube placement, a shorter postoperative hospital stay, and a lower peak C-reactive protein value, despite a longer operative time. The VATS group also had significantly longer survival than the thoracotomy group [5-year overall survival, 100% vs. 87%, respectively (p = 0.01); 5-year disease-free survival, 100% vs. 86% (p = 0.03)]. CONCLUSIONS These findings suggest that VATS may have better long-term as well as short-term outcomes than thoracotomy for patients with early-stage NSCLC.

Abstract
Background Radical lymph node dissection (LND) plays a major role in the treatment of non-small cell lung cancer (NSCLC). This study presents the analysis of the results after uniportal video-assisted thoracoscopy (VATS) lymphadenectomy during anatomical lung resections for NSCLC, focusing on pathological nodal upstaging. Any possible risk factor affecting nodal upstaging was also investigated. Methods The prospectively collected clinical data of 136 patients undergone uniportal VATS anatomical lung resections, from June 2012 to September 2017, were reviewed. In particular, all details inherent the clinical and pathological node stage and any possible risk factor affecting nodal upstaging were analyzed. Results The patient population consisted of 90 males and 46 females; their mean age was 67.42±10.64 years. The mean number of lymph nodes retrieved during uniportal VATS lymphadenectomy was 20.14±10.73 (7.27±5.90 and 12.60±7.96 in N1 and N2 stations, respectively). The incidence of nodal upstaging was 13.3% (18 cases). In particular there was a N0-1 upstaging in 10 cases (7.4%), a N1-2 upstaging in 3 (2.2%) and a N0-2 in 4 (3%). The ROC analysis showed that the resection of 18 lymph nodes was the best predictor of a general upstaging with an AUC-ROC of 0.595, while the resection of 7 hilar lymph nodes was the best predictor of N1 upstaging (AUC-ROC: 0.554) and 11 mediastinal nodes was the best predictor of N2 upstaging (AUC-ROC: 0.671). The number of positive lymph nodes of stations 5-6 (OR: 2.035, 95% CI: 1.082-3.826, P=0.027) and stations 2-3-4 (OR: 6.198, 95% CI: 1.580-24.321, P=0.009) were confirmed to be the only independent risk factors for N2 upstaging by multivariate analysis. Conclusions According to our experience, uniportal VATS allows a safe and effective radical lymphadenectomy, with a satisfactory pathological nodal upstaging, comparable to other minimally invasive techniques.

Abstract
OBJECTIVES In the literature, inconsistent associations between the primary locations of lung adenocarcinomas (ADCs) with patient prognosis have been reported, due to varying definitions for central and peripheral locations. In this study, we investigated the clinical characteristics and prognoses of ADCs located in the main bronchus. METHODS A total of 397,189 lung ADCs registered from 2004 to 2013 in the National Cancer Database (NCDB) were extracted and divided into main bronchus-located ADCs (2.5%, N = 10,111) and non-main bronchus ADCs (97.5%, N = 387,078). The ADCs located in the main bronchus and those not in the main bronchus were compared in terms of patient prognosis, lymph node involvement, distant metastases and other clinical features, including rate of curative-intent resection, histologic grade, and stage. RESULTS ADCs located in the main bronchus had significantly worse patient survival than those in the non-main bronchus, both for all patients (HR = 1.82, 95% CI 1.78-1.86) and for those undergoing curative-intent resection (HR = 2.49, 95% CI 2.23-2.78). Furthermore, ADCs located in the main bronchus had a significantly higher rate of lymph node involvement and distant metastasis than those not in the main bronchus, when stratified by tumor size (trend test, p < e-16). Multivariate analysis of overall survival showed that main bronchus location is a prognostic factor (HR = 1.15, 95% CI 1.08-1.23) independent of other clinical factors. CONCLUSIONS Main bronchus location is an independent predictor for metastasis and worse outcomes irrespective of stage and treatment. Tumor primary location might be considered in prognostication and treatment planning.

Abstract
BACKGROUND Despite the slow adoption of minimally invasive lobectomy (MIL), it is now a preferred approach for early lung cancer. Nevertheless, ongoing concerns about MIL oncologic effectiveness has led to calls for prospective, randomized trials. METHODS Retrospective analysis of on-line databases, collected readings, and other scholarly experiences of the experienced authors were used to construct this review. All available reports that contained long-term survival comparisons for open versus MIL were tabulated. RESULTS The preponderance of limited randomized and numerous large propensity-matched database analyses indicate equivalent or improved long-term MIL survival for early-stage disease. MIL lymph node dissection quality has been challenged; however, this was attributed to MIL avoidance of central tumors in early reports. Although technical inadequacies for MIL should be amplified for advanced cancer resections, early reports show no such concern. In fact, for special populations such as older, frail patients, evidence is much stronger that MIL confers a survival advantage. CONCLUSIONS MIL is an oncologically equivalent operation with substantially less morbidity, especially in frail populations. It is reasonable to suggest that MIL should be the technique of choice, even a quality indicator, for lobectomy.

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
Nodal upstaging after surgical intervention for non-small cell lung cancer (NSCLC) is defined as the presence of unsuspected pathologic hilar (pN1) or mediastinal (pN2) disease detected during the final histopathologic evaluation of surgical specimens. The prevalence of pathologic nodal upstaging is used as a quality measure for the definition of the completeness of the nodal dissection. Risk factors for nodal upstaging may be patient-related (history of tuberculosis, rheumatoid arthritis, and diabetes mellitus), or tumor-related (central tumor, higher T stage, higher SUVmax value, or adenocarcinoma). Actually, the theorical superiority of a minimally invasive resections is the lymph node dissection. Studies may suggest that, expert video-assisted thoracoscopic surgery (VATS) surgeon could do similar lymph node dissection as it is done in open. Robotic surgeons may replicate the results of lymph node dissection in the open techniques. The possible reason for this is the instrumental superiority provided by the higher technology.

Nodal recurrence after stereotactic body radiotherapy for early stage non-small cell lung cancer: Incidence and proposed risk factors. Cancer Treat Rev 2017; 56:8-15.

Abstract
Stereotactic body radiotherapy (SBRT) is an alternative to surgery for patients with early stage non-small cell lung cancer (NSCLC) who are inoperable due to comorbid disease or who refuse surgery. SBRT results in an excellent local control rate of more than 90%, which is comparable to surgery, while short and long-term overall toxicity is low. Surgically treated patients are often more extensively staged pre-operatively, e.g. with endobronchial ultrasound and/or mediastinoscopy, and typically undergo intra-operative lymph node dissection or sampling. Occult nodal metastases (ONM), detected by lymph node dissection, have been shown to increase the incidence of regional recurrence (RR) after surgery, which is associated with poor outcome. In patients undergoing SBRT, however, definite pathological nodal staging is lacking and so other ways to identify patients at high risk for ONM and RR are desirable. The aim of this systematic review is to summarize the incidence of, and risk factors for, RR after SBRT and compare these to those after surgery. The available evidence shows the incidence of RR after SBRT or surgery to be comparable, despite more elaborate pre- and intra-operative lymph node evaluation in surgical patients. However, the fact that this finding is based on mostly retrospective studies in which the majority of patients treated with SBRT were inoperable, needs to be taken into consideration. For now, there is no evidence that inoperable clinical stage I patients with no indication of pathological lymph nodes on PET/CT will benefit from more invasive lymph node staging prior to SBRT.
