Outcomes of Patients Undergoing Segmentectomy for Occult Node-Positive Clinical Stage IA Lung Cancer. Ann Thorac Surg 2024:S0003-4975(24)00448-X. [PMID: 38866198 DOI: 10.1016/j.athoracsur.2024.05.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 05/03/2024] [Accepted: 05/20/2024] [Indexed: 06/14/2024]
Abstract
BACKGROUND Results of recent clinical trials suggest that segmentectomy may be an acceptable alternative to lobectomy for selected patients with early-stage non-small cell lung cancer (NSCLC). Increased use of segmentectomy may result in a concomitant increase in occult node-positive (N+) disease on surgical pathology examination. The optimal management for such patients remains unknown. METHODS Clinicopathologic data were abstracted from a prospective institutional database to identify patients with pathologic N+ disease after segmentectomy for cT1 N0 M0 NSCLC. Propensity score matching identified a comparable lobectomy cohort for assessment of cumulative incidence of recurrence and overall survival (OS). RESULTS Of 759 included patients, 27 (4%) had nodal upstaging on the final pathology report. Of these 27 patients, 4 (15%) had skip metastasis to N2 stations, and 20 (74%) received adjuvant therapy; no completion lobectomies were performed. Ten patients (37%) had disease recurrence: 3 isolated locoregional (11%) and 7 distant (26%). The median time to recurrence among patients with recurrence was 1.8 years; OS after recurrence was 3.4 years. After 5:1 matching with 109 patients who underwent lobectomy, all variables were balanced between the groups, except pathologic N2 stage and open surgical approach. The 5-year cumulative incidence of recurrence was not significantly different between segmentectomy and lobectomy (42% vs 52%, respectively; Gray's P = .1). The 5-year OS (63% and 50%) and rate of locoregional recurrence (12% vs 13%) were not statistically different between the groups. CONCLUSIONS Patients with occult N+ disease after segmentectomy for cT1 N0 M0 NSCLC had limited isolated locoregional recurrences and outcomes similar to those in patients who underwent lobectomy. Lobectomy may not provide an advantage in these patients.

The use of diagnostic complex robotic-assisted segmentectomy in the management of incidental and screen-detected pulmonary nodules. Eur J Cardiothorac Surg 2024; 65:ezae139.

Abstract
OBJECTIVES Robotic-assisted thoracoscopic surgery (RATS) facilitates complex pulmonary segmentectomy which offers one-stage diagnostic and therapeutic management of small pulmonary nodules. We aimed to explore the potential advantages of a faster, simplified pathway and earlier diagnosis against the disadvantages of unnecessary morbidity in benign cases. METHODS In an observational study, patients with small, solitary pulmonary nodules deemed suspicious of malignancy by a multidisciplinary team were offered surgery without a pre or intraoperative biopsy. We report our initial experience with RATS complex segmentectomy (using >1 parenchymal staple line) to preserve as much functioning lung tissue as possible. RESULTS Over a 4-year period, 245 RATS complex segmentectomies were performed; 140 right: 105 left. A median of 2 (1-4) segments was removed. There was no in-hospital mortality and no requirement for postoperative ventilation. Complications were reported in 63 (25.7%) cases, of which 36 (57.1%) were hospital-acquired pneumonia. A malignant diagnosis was found in 198 (81%) patients and a benign diagnosis in 47 (19%). The malignant diagnoses included: adenocarcinoma in 136, squamous carcinoma in 31 and carcinoid tumour in 15. The most frequent benign diagnosis was granulomatous inflammation in 18 cases. CONCLUSIONS RATS complex segmentectomy offers a precise, safe and effective one-stop therapeutic biopsy in incidental and screen-detected pulmonary nodules.

J Surg Res 2024; 296:674-680.

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.

Abstract
Surgery remains an essential element of the multimodality radical treatment of patients with early-stage nonsmall cell lung cancer. In addition, thoracic surgery is one of the key specialties involved in the lung cancer tumour board. The importance of the surgeon in the setting of a multidisciplinary panel is ever-increasing in light of the crucial concept of resectability, which is at the base of patient selection for neoadjuvant/adjuvant treatments within trials and in real-world practice. This review covers some of the topics which are relevant in the daily practice of a thoracic oncological surgeon and should also be known by the nonsurgical members of the tumour board. It covers the following topics: the pre-operative selection of the surgical candidate in terms of fitness in light of the ever-improving nonsurgical treatment alternatives unfit patients may benefit from; the definition of resectability, which is so important to include patients into trials and to select the most appropriate radical treatment; the impact of surgical access and surgical extension with the evolving role of minimally invasive surgery, sublobar resections and parenchymal-sparing sleeve resections to avoid pneumonectomy.

Abstract
The treatment paradigm for patients with stage II/III non-small-cell lung cancer (NSCLC) is rapidly evolving. We performed a modified Delphi process culminating at the Early-stage Lung cancer International eXpert Retreat (ELIXR23) meeting held in Montreal, Canada, in June 2023. Participants included medical and radiation oncologists, thoracic surgeons and pathologists from across Quebec. Statements relating to diagnosis and treatment paradigms in the preoperative, operative and postoperative time periods were generated and modified until all held a high level of consensus. These statements are aimed to help guide clinicians involved in the treatment of patients with stage II/III NSCLC.

Abstract
To investigate the perioperative outcomes of patients who underwent robot-assisted thoracoscopic (RATS) segmentectomy for identifying the intersegmental plane (ISP) by improved modified inflation-deflation (MID) combined with near-infrared fluorescence imaging with the intravenous indocyanine green (ICG) method and to assess the feasibility of this method in a large-scale cohort according to the type of segmentectomy performed. We retrospectively analysed the perioperative data of a total of 155 consecutive patients who underwent RATS segmentectomy between April 2020 and December 2021. Data from the operation, including the demarcation status of the intersegmental plane, were analysed retrospectively. The mean operative time and estimated blood loss were 125.56 ± 36.32 min and 41.81 ± 49.18 mL, respectively. Good demarcation of the intersegmental plane was observed in 150 (96.77%) patients, with no correlation with the type of resected segments or the surgical method. Postoperative complications of Clavien-Dindo classification grade 3 or more were observed in 4 patients (2.58%), and no ICG-related adverse events were noted. Demarcation of the intersegmental plane by improved MID combined with ICG is feasible regardless of the type of segmentectomy and can be commonly applied in robot-assisted segmentectomy.

Abstract
Lung cancer is the most common cancer killer in the world. The standard of care for surgical treatment of non-small cell lung cancer has been lobectomy. Recent studies have identified that sublobar resection has non-inferior survival rates compared to lobectomy, however. Sublobar resection may increase the number of patients who can tolerate surgery and reduce postoperative pulmonary decline. Sublobar resection appears to have equivalent results to surgery in patients with small, peripheral tumors and no lymph node disease. As the utilization of segmentectomy increases, there may be some centers that perform this operation more than other centers. Care must be taken to ensure that all patients have access to this modality. Future investigations should focus on examining the outcomes from segmentectomy as it is applied more widely. When employed on a broad scale, morbidity and survival rates should be monitored. As segmentectomy is performed more frequently, patients may experience improved postoperative quality of life while maintaining the same oncologic benefit.

Comparison of Short-Term Outcomes Between Robot-Assisted and Video-Assisted Segmentectomy for Small Pulmonary Nodules: A Propensity Score-Matching Study. Ann Surg Oncol 2023; 30:2757-2764. [PMID: 36774436 DOI: 10.1245/s10434-023-13179-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Accepted: 01/02/2023] [Indexed: 02/13/2023]
Abstract
BACKGROUND Our study aimed to compare the short-term outcomes between robot-assisted segmentectomy (RAS) and video-assisted segmentectomy (VAS) for small pulmonary nodules. METHODS The study included of 299 segmentectomies (132 RAS and 167 VAS procedures) for small pulmonary nodules between June 2018 and November 2021. The patients were divided into two groups: the RAS group and the VAS group. Propensity score-matching (PSM) analysis was performed to minimize bias. A logistic regression model was performed to identify the independent risk factors associated with complications. RESULTS Before PSM, the following clinical variables were not balanced: age (P = 0.004), tumor size (P < 0.001), forced expiratory volume for 1 s (FEV1), and FEV1 percentage (P < 0.001). The patients with RAS had a shorter operative time (P = 0.014), less blood loss, a shorter postoperative hospital stay, less use of strong opioids, less drainage on postoperative day 1, and less postoperative total drainage, but more cost (all P < 0.001). Conversion to open surgery was performed for two patients in the VAS group but none in the RAS group. After PSM, 53 pairs were successfully matched. The data again suggested that the patients with RAS had less blood loss, a shorter postoperative hospital stay, and less use of strong opioids, but more cost (all P < 0.001). The operation time also was shorter in the RAS group, with a borderline statistically significant P value (0.053). CONCLUSIONS In our study, RAS had better short-term outcomes than VAS, indicating a safer and more efficient technique than VAS.

Abstract
Sublobar resections are commonly performed operations that have seen an increase in applicability. The sublobar approach, comprising segmentectomy and wedge resections, can provide lung preservation and thus is better tolerated in select patients in comparison to lobectomy. These operations are offered for a variety of benign and malignant lesions. Understanding the indications and technical aspects of these approaches is paramount as improvements in lung cancer screening protocols and the imaging modalities has led to an increase in the detection of early-stage cancer. In this article, we discuss the anatomy, indications, technical approaches, and outcomes for sublobar resection.

Abstract
BACKGROUND Current recommendations for segmentectomy for non-small cell lung cancer (NSCLC) include size ≤2 cm, margins ≥ 2 cm, and no nodal involvement. This study further stratifies the selection criteria for segmentectomy using the National Cancer Database (NCDB). METHODS The NCDB was queried for patients with high-grade (poorly/undifferentiated) T1a/b peripheral NSCLC (tumor size ≤2 cm), who underwent either lobectomy or segmentectomy. Patients with pathologic node-positive disease or who received neoadjuvant/adjuvant treatments were excluded. Propensity score analysis was used to adjust for differences in pretreatment characteristics. RESULTS 11 091 patients were included with 10 413 patients (93.9%) treated with lobectomy and 678 patients (6.1%) underwent segmentectomy. In a propensity matched pair analysis of 1282 patients, lobectomy showed significantly improved median survival of 88.48 months vs 68.30 months for segmentectomy, P = .004. On multivariate Cox regression, lobectomy was associated with significantly improved survival (hazard ratio (HR): .81, 95% CI .72-.92, P = .001). Subgroup analysis of propensity score matched patients with a Charlson-Deyo comorbidity score (CDCC) of 0 also demonstrated a trend of improved survival with lobectomy. DISCUSSION Lobectomy may confer significant survival advantage over segmentectomy for high-grade NSCLC (≤2 cm). More work is needed to further stratify various NSCLC histologies with their respective grades allowing more comprehensive selection criteria for segmentectomy.

Size Measurement and Segmentectomy Resection Margin of Early-Stage Lung Adenocarcinoma Manifesting on Virtual 3D Imagery and Pathology: A Pilot Correlation Study. J Clin Med 2022; 11:jcm11206155. [PMID: 36294475 PMCID: PMC9605571 DOI: 10.3390/jcm11206155] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Revised: 10/03/2022] [Accepted: 10/11/2022] [Indexed: 12/24/2022] Open
Abstract
Background: The objective of our study was to assess if 3D reconstructed images could be extrapolated to reflect pathologies, as evaluated by early-stage lung adenocarcinoma tumor size and simulated segmentectomy resection margin. Methods: Retrospectively selected patients (n = 18) who underwent segmentectomy at Changhua Christian Hospital between 2012 and 2018 and then had pulmonary 3D reconstruction using Ziostation2 were included in our study. Tumor size and simulated segmentectomy resection distance on a 3D model were measure and compared to pathology. Results: Both tumor size and segmentectomy resection margin showed positive correlations between 3D image measurements and pathological measurements. The resection margin showed a stronger correlation and was beneficial in pre-operative planning. Conclusions: A 3D reconstructed model aided understanding of pulmonary anatomy, prompting confidence in surgical approaches and ensured segmentectomy outcome success. Regardless of age and pulmonary function, 3D simulation can accurately mimic segmentectomy, making it a simple, effective and feasible pre-operative planning tool.

J Thorac Dis 2022; 14:2357-2386.

Abstract
Background Clinical decision-making for patients with stage I lung cancer is complex. It involves multiple options (lobectomy, segmentectomy, wedge, stereotactic body radiotherapy, thermal ablation), weighing multiple outcomes (e.g., short-, intermediate-, long-term) and multiple aspects of each (e.g., magnitude of a difference, the degree of confidence in the evidence, and the applicability to the patient and setting at hand). A structure is needed to summarize the relevant evidence for an individual patient and to identify which outcomes have the greatest impact on the decision-making. Methods A PubMed systematic review from 2000-2021 of outcomes after lobectomy, segmentectomy and wedge resection in generally healthy patients is the focus of this paper. Evidence was abstracted from randomized trials and non-randomized comparisons with at least some adjustment for confounders. The analysis involved careful assessment, including characteristics of patients, settings, residual confounding etc. to expose degrees of uncertainty and applicability to individual patients. Evidence is summarized that provides an at-a-glance overall impression as well as the ability to delve into layers of details of the patients, settings and treatments involved. Results In healthy patients there is no short-term benefit to sublobar resection vs. lobectomy in randomized and non-randomized comparisons. A detriment in long-term outcomes is demonstrated by adjusted non-randomized comparisons, more marked for wedge than segmentectomy. Quality-of-life data is confounded by the use of video-assisted approaches; evidence suggests the approach has more impact than the resection extent. Differences in pulmonary function tests by resection extent are not clinically meaningful in healthy patients, especially for multi-segmentectomy vs. lobectomy. The margin distance is associated with the risk of recurrence. Conclusions A systematic, comprehensive summary of evidence regarding resection extent in healthy patients with attention to aspects of applicability, uncertainty and effect modifiers provides a foundation on which to build a framework for individualized clinical decision-making.

Abstract
Identifying intersegmental planes is considered the key step during segmentectomy. Several techniques, including modified inflation-deflation techniques, target-segment jet ventilation, and infrared-fluorescence-enhanced methods, have been reported for the identification of intersegmental planes. However, limitations of these methods have also been reported. Here, we described an improved collateral ventilation method to identify the inflation-deflation line without waiting and without any auxiliary materials needed during robotic-assisted anatomic segmentectomy. We present this handy technique of identifying the intersegmental planes and comment on its advantages, including decreased operative time and improved clarity of the inflation-deflation line.

Abstract
BACKGROUND Minimal literature exists evaluating the impact of the extent of resection on survival in patients with small, early-stage non-small cell lung cancer (NSCLC) found to have occult nodal disease (OND). We hypothesized that sublobar resection has comparable overall survival to patients undergoing lobectomy for clinical Stage IA NSCLC that harbors OND. METHODS The National Cancer Database was reviewed for identification of patients with clinical Stage IA NSCLC who underwent wedge resection, segmentectomy or lobectomy and were found to have OND. Overall survival was compared between groups and a multivariate Cox-Regression model identified factors associated with worse survival. RESULTS OND occurred in 6.1% of all patients with clinical Stage IA disease undergoing resection. Patients undergoing wedge resection and segmentectomy found to have OND were older (67.6 ± 9.6 vs. 66.1 ± 9.3 vs. 65.6 ± 9.5, p=0.004), and had more advanced pathologic stage (pStage III: 68.7% vs. 50.5% vs. 41.5%, p<0.001) than those receiving lobectomy. There was no difference in the median overall survival between segmentectomy and lobectomy (68.5 months vs. 57.6, p=0.200.) However, wedge resection was independently associated with worse overall survival when controlling for other preoperative variables, hazard ratio: 1.23 (1.01 - 1.51), p=0.042. CONCLUSIONS Review of the National Cancer Database suggests that there is no improvement in overall survival in patients undergoing lobectomy versus segmentectomy in carefully selected patients with clinical Stage IA NSCLC harboring occult nodal disease. However, those undergoing wedge resection may have worse overall survival than those undergoing both lobectomy and segmentectomy.

Abstract
BACKGROUND Part-solid lung adenocarcinoma appears as a heterogeneous subgroup, and its surgical management is controversial. This study aimed to elucidate whether preoperative carcinoembryonic antigen, a time-honored tumor marker, can be used as a prognostic factor that contributes to its management. METHODS We retrospectively reviewed consecutive patients with clinical-T1a-cN0M0 part-solid adenocarcinoma who underwent surgical resection between January 2011 and December 2015 at two institutions. RESULTS Overall, 288 patients were identified. The median age was 69 years with 176 patients (61%) being female. The median follow-up time was 5.6 years. Lymph node metastases were found in 6 (15%) of 41 patients with elevated carcinoembryonic antigen levels, while 10 (4.0%) of 247 patients had normal carcinoembryonic antigen levels (P = 0.016). The 5-year overall survival rates in patients with normal and elevated carcinoembryonic antigen levels were 96.9% and 87.2%, respectively (P = 0.006), and the 5-year relapse-free survival rates were 91.8% and 62.8%, respectively (P < 0.001). The multivariable analysis revealed that preoperative carcinoembryonic antigen level was a significant prognostic factor for relapse-free survival (hazard ratio [HR] = 2.92, 95% confidence interval [CI] = 1.63-5.25, P < 0.001). Among the patients with elevated carcinoembryonic antigen levels, the 5-year overall survival rates in those undergoing lobar resection and segmentectomy were 87.0% and 88.9%, respectively (P = 0.59), and the 5-year relapse-free survival rates were 61.7% and 66.7%, respectively (P = 0.84). CONCLUSIONS Our data suggest that preoperative carcinoembryonic antigen level appears to be an important predictor of postoperative survival outcomes in early-stage part-solid adenocarcinoma. Further studies are required to optimize management of patients with elevated preoperative carcinoembryonic antigen levels, although segmentectomy appeared acceptable in those patients.

Abstract
Background Preoperative mediastinal staging is crucial for the optimal management of clinical stage I non-small cell lung cancer (NSCLC). Purpose To develop a deep learning signature for N2 metastasis prediction and prognosis stratification in clinical stage I NSCLC. Materials and Methods In this retrospective study conducted from May 2020 to October 2020 in a population with clinical stage I NSCLC, an internal cohort was adopted to establish a deep learning signature. Subsequently, the predictive efficacy and biologic basis of the proposed signature were investigated in an external cohort. A multicenter diagnostic trial (registration number: ChiCTR2000041310) was also performed to evaluate its clinical utility. Finally, on the basis of the N2 risk scores, the instructive significance of the signature in prognostic stratification was explored. The diagnostic efficiency was quantified with the area under the receiver operating characteristic curve (AUC), and the survival outcomes were assessed using the Cox proportional hazards model. Results A total of 3096 patients (mean age ± standard deviation, 60 years ± 9; 1703 men) were included in the study. The proposed signature achieved AUCs of 0.82, 0.81, and 0.81 in an internal test set (n = 266), external test cohort (n = 133), and prospective test cohort (n = 300), respectively. In addition, higher deep learning scores were associated with a lower frequency of EGFR mutation (P = .04), higher rate of ALK fusion (P = .02), and more activation of pathways of tumor proliferation (P < .001). Furthermore, in the internal test set and external cohort, higher deep learning scores were predictive of poorer overall survival (adjusted hazard ratio, 2.9; 95% CI: 1.2, 6.9; P = .02) and recurrence-free survival (adjusted hazard ratio, 3.2; 95% CI: 1.4, 7.4; P = .007). Conclusion The deep learning signature could accurately predict N2 disease and stratify prognosis in clinical stage I non-small cell lung cancer. © RSNA, 2021 Online supplemental material is available for this article.

Comparison of operative and postoperative characteristics and outcomes between thoracoscopic segmentectomy and lobectomy for non-small-cell lung cancer: a propensity score matching study from the Italian VATS Group Registry. Eur J Cardiothorac Surg 2021; 61:533-542. [PMID: 34643695 DOI: 10.1093/ejcts/ezab430] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Revised: 08/10/2021] [Accepted: 08/19/2021] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVES Only few studies compared the surgical morbidity and mortality of thoracoscopic segmentectomy versus lobectomy for non-small-cell lung cancer, in particular, by relating the segmental resections with the corresponding anatomical lobes. METHODS We enrolled a total of 7487 patients who underwent VATS lobectomy (7269) or segmentectomy (218) from January 2014 to July 2019. A propensity score matching approach was used to account for potential confounding factors between the 2 groups. After matching, 349 lobectomies and 208 segmentectomies were included in the analysis. We analysed the operative and postoperative outcomes of video-assisted anatomical segmentectomy compared with video-assisted lobectomy and, in details, the results of segmentectomy with its corresponding lobectomy in a large cohort of patients from the Italian VATS Group Registry. RESULTS The overall conversion rate to thoracotomy was not statistically different between the groups (27 patients 8% vs 7 patients 3%, P = 0.1). The lobectomy group had a greater number of resected lymph nodes (median 11 vs 8, P = 0.006). No significant differences were detected in 30-day mortality (1.4%, 5 patients vs 0.9%, 2 patients), overall complications (18%, 62 patients vs 14%, 29 patients) and prolonged air leakage (31 patients, 9% vs 12 patients, 6%) between lobectomy and segmentectomy, respectively. No statistical differences were found regarding the median duration of drainage (3.2 days, P = 1) and the overall median length of hospital stay (6.4 days, P = 0.1) between the 2 groups. In the context of segmentectomy versus corresponding lobectomy, the right upper lobectomy compared with right upper segmentectomy showed a higher number of resected lymph nodes (P = 0.027). No statistical differences were reported in terms of conversion rate and postoperative complication and mortality. CONCLUSIONS Segmentectomy could be considered a safe procedure without significant differences compared to thoracoscopic lobectomy in terms of postoperative morbidity and mortality.

Ann Surg Oncol 2021; 28:8398-8411.

Abstract
BACKGROUND The choice between wedge resection and segmentectomy as a sublobar resection method for patients with cT1N0 lung cancer remains debatable. This study aimed to evaluate the clinical outcomes after wedge resection and segmentectomy for patients with cT1N0 lung adenocarcinoma. METHODS The study enrolled 1002 consecutive patients with cT1N0 lung adenocarcinoma who underwent sublobar resection at the authors' institution between 2011 and 2017. A propensity score-matching analysis was used to compared the clinical outcomes between the wedge resection and segmentectomy groups. RESULTS Wedge resection was performed for 810 patients (80.8%), and segmentectomy was performed for 192 patients (19.2%). Wedge resection resulted in better perioperative outcomes than segmentectomy. The multivariate analysis showed that the significant risk factors for poor disease-free survival (DFS) were elevated preoperative serum carcinoembryonic antigen levels, total tumor diameter greater than 2 cm, and a consolidation-to-tumor (C/T) ratio higher than 50%. After propensity-matching, no differences in overall survival or DFS were noted between the two matched groups. However, subgroup analysis showed that segmentectomy was associated with better DFS than wedge resection (p = 0.039) for the patients with a tumor diameter greater than 2 cm and a C/T ratio higher than 50%. CONCLUSION Segmentectomy is the appropriate surgical method for sublobar resection in cT1N0 lung adenocarcinoma patients with a tumor diameter greater than 2 cm and a C/T ratio higher than 50%. Wedge resection may be a safe and feasible sublobar resection method for patients with a tumor diameter of 2 cm or smaller or a C/T ratio of 50% or lower.

Abstract
BACKGROUND It is unclear whetherrobotic segmentectomies are advantageous. We describe our experience with the robot, comparing patient populations and outcomes with videoscopic thoracic surgery (VATS) and open resection. METHODS Patients who received anatomic segmentectomy from 2004-2019 were reviewed. Resection methods were categorized as robotic, VATS, or open. Segmentectomies were categorized as simple or complex. Baseline characteristics and perioperative outcomes were analyzed from 2015-2019 due to implementation of ERAS protocol. RESULTS Since 2004, there has been an increase in segmentectomies, including robotic and complex segmentectomies. There were 222 segmentectomies from 2015-2019, of which 77(35%) were robotic, 40(18%) VATS, and 105(47%) open. Complex segmentectomies were higher in the robotic group compared to VATS and open (45% vs. 15% vs. 22%; p<0.001), operative time for robotic resections were also longer compared to VATS and open (205 vs. 147 vs. 147 minutes; p<0.001), but had lower blood loss (50 vs. 75 vs. 100 ml; p<0.001), shorter chest tube days (2 vs. 2 vs. 3 days; p=0.004) and length of stay (3 vs. 3 vs. 4 days; p<0.001). Perioperative mortality was low in all groups. No robotic segmentectomy converted to open compared to 7.5% for VATS (p=0.038). Prolonged air leak was lower for robotic compared to open (4% vs. 13%; p=0.038). CONCLUSIONS Robotic segmentectomy has increased in our institution, with concurrent rise in atypical segmentectomies. Despite performing more complex procedures, there were no conversions, and low perioperative morbidity and mortality. Our results suggest that the robotic platform can facilitate performance of complex anatomic segmentectomies.

Abstract
Background Compared with lobectomy, the anatomical structure of the lung segment is relatively complex and easy to occur variation, thus it increases the difficulty and risk of precise segmentectomy. The application of three-dimensional computed tomography bronchography and angiography (3D-CTBA) combined with a three-dimensional printing (3D printing) model can ensure the safety of operation and simplify the surgical procedure to a certain extent. We aimed to estimate the value of 3D-CTBA and 3D printing in thoracoscopic precise pulmonary segmentectomy. Methods We retrospectively reviewed the clinical data of 65 patients who underwent anatomical segmentectomy at the Affiliated Hospital of Shaoxing University from January 2019 to August 2020. The patients were divided into two groups: a 3D-CTBA combined with 3D printing group (30 patients) and a general group (35 patients). The perioperative data of the two groups were compared. Results Compared with the general segmentectomy group at the same period in our center, the surgery time of the group guided by 3D-CTBA and 3D printing was significantly shorter. Intraoperative blood loss in the 3D-CTBA and 3D printing group was also apparently lower than in the general group. Hospital stay and postoperative chest tube duration showed no significant differences between the two groups, and neither did postoperative complications such as pneumonia, hemoptysis, arrhythmia, and pulmonary air leakage. Conclusions 3D-CTBA combined with 3D printing clearly identifies the precise pulmonary segmental structures, avoids intraoperative accidental injury, reduces intraoperative blood loss, shortens the operation time and improves the safety of thoracoscopic pulmonary segmentectomy in stage IA non-small cell lung cancer (NSCLC).

Abstract
BACKGROUND Despite its popularity in recent years, segmentectomy still faces a challenge: the accurate delineation of the intersegmental plane, especially in complex segmentectomy. In this study, we describe a method using collateral ventilation to create an inflation-deflation line for video-assisted thoracoscopic surgery (VATS) segmentectomy and evaluated its efficacy in complex segmentectomy by comparing it with simple segmentectomy. METHODS Enrolled in the study were 264 patients who underwent VATS segmentectomy from January 2017 to September 2018. We classified the clarity of the inflation-deflation line into 4 grades, and the procedures of grade 3 or 4 were considered successful. Meanwhile, we performed a propensity score matching analysis to compare complex and simple segmentectomy. RESULTS Complete resection with free margins was achieved in all patients. In inflation-deflation line clarity evaluation, 245 patients were classified as grade 4 (92.8%), 10 as grade 3 (3.8%), 8 as grade 2 (3.0%), and 1 as grade 1 (0.4%). Procedural success (grade 3 or 4) was achieved in 255 patients (96.6%). Prolonged air leak (>5 days) was observed in 11 patients (4.2%). Propensity matching generated 83 pairs of well-matched patients. The proportion of procedural success and the incidence of prolonged air leak (>5 days) were similar in both groups. However, compared with simple segmentectomy, complex segmentectomy was associated with a longer median operative time (159 versus 135 minutes; P < .001). CONCLUSIONS Collateral ventilation method is simple, safe, and effective in VATS segmentectomy to identify the intersegmental plane, and also well-adapted for complex segmentectomy.

In order to treat the illness with minimal invasion and preserve lung function to the greatest possible extent, there has been an increasing tendency towards treating early-stage NSCLC by segmentectomy. However, questions remain regarding whether patients may benefit from this procedure considering the surgical and oncological outcomes. Whether adequate margin distance and lymph node dissection may be achieved is one of the most important issues associated with this procedure. The present study reviews the prognosis of segmentectomy in the treatment of stage IA NSCLC.

Abstract
Background Spread through air space (STAS) is a risk factor for disease recurrence in patients with stage IA lung adenocarcinoma (LUAD) who undergo limited resection. Preoperative prediction of STAS could help intraoperative surgical decision-making in small LUAD patients. The aim of the study was to evaluate the predictive value of radiological features on STAS in stage cIA LUAD. Methods A case-control study was designed through retrospective analysis of the radiological features of patients who underwent curative surgery for LUAD with a clinical tumor size ≤3 cm. Univariable and multivariable analyses were used to identify the independent risk factors for STAS. The predicted probability of STAS was calculated by a specific formula. Receiver operating characteristic (ROC) curves were used to determine a cut-off value with appropriate specificity while maintaining high sensitivity for STAS positivity. Results STAS was frequently observed in acinar predominant (P<0.001), micropapillary predominant (P<0.001) and solid predominant (P<0.001) tumors and was significantly associated with larger pT size (P<0.001), presence of micropapillary component (P<0.001), lymphovascular invasion (LVI) (P<0.001), visceral pleura invasion (VPI) (P<0.001), both N1 and N2 lymph node metastasis (P<0.001) and ALK rearrangement (P<0.001). STAS-positivity was significantly associated with the presence of cavitation (P=0.047), lobulation (P=0.009), air bronchogram (P<0.001), and vascular convergence (P=0.016) and was also associated with greater maximum tumor diameter (P<0.001), maximum solid component diameter (P<0.001), maximum tumor area (P<0.001), consolidation/tumor ratio (CTR) (P<0.001), tumor disappearance ratio (TDR) (P<0.001) and computed tomography (CT) value (P<0.001). Multivariable analysis showed that STAS was associated with air bronchogram (P=0.042), maximum tumor diameter (P=0.015), maximum solid component diameter (P=0.022) and CTR (P<0.001). The ROC curve showed that the area under the curve (AUC) was 0.726 in the model for predicting STAS, with a sensitivity and specificity of 95.2% and 36.8%, respectively. Conclusions STAS-positive LUAD was associated with air bronchogram, maximum tumor diameter, maximum solid component diameter and CTR. These radiological features could predict STAS with excellent sensitivity but inferior specificity.

[PMID: 33061635 PMCID: PMC7534848 DOI: 10.2147/cmar.s266376] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Accepted: 08/28/2020] [Indexed: 12/24/2022] Open
Abstract
Background To investigate postoperative temporary consequences of the enrolled patients with lung adenocarcinoma. Patients and Methods We analyzed the clinical data of patients with lung adenocarcinoma admitted by the same surgical team of Peking Union Medical College Hospital (PUMCH) from July 2019 to December 2019. Statistical methods including propensity score matching (PSM) analysis was used to analyze the differences among them. Results A total of 108 patients were enrolled, including 50 patients with sublobar resection and 58 patients with lobectomy. Before PSM, there were statistically significant differences in age (p=0.015), hospitalization costs (p=0.042), lymphadenectomy (p=0.000), pathological staging (p=0.000), number of lymph nodes removed (p=0.000), number of positive lymph nodes (p=0.034), chest drainage duration (p=0.000), total chest drainage (p=0.000), length of postoperative hospital stays (p=0.000), postoperative D-dimer level (p=0.030) and perioperative lymphocyte margin (LM) (p=0.003) between sublobar resection and lobectomy. After PSM, there were statistical differences in number of lymph nodes removed (p=0.000), chest drainage duration (p=0.031) and total chest drainage (p=0.002) between sublobar resection and lobectomy. Whether with PSM analysis or not, there were no significant differences in other blood test results, such as inflammation indicators, postoperative neutrophil-lymphocyte ratio (NLR), albumin level, perioperative activity of daily living (ADL) scale scoring margin, complications, postoperative admission to intensive care unit (ICU) and readmission within 30 days. NLR was associated with total chest drainage (p=0.000), length of postoperative hospital stays (p=0.000), postoperative D-dimer level (p=0.050) and ADL scale scoring margin (p=0.003) between sublobar resection and lobectomy. Conclusion Sublobar resection, including wedge resection and segmentectomy, was as safe and feasible as lobectomy in our study, and they shared similar short-term outcomes. Postoperative NLR could be used to detect the clinical outcomes of patients. Secondary resectability of pulmonary function (SRPF) should be the main purpose of sublobar resection.

Abstract
Background Current practice guidelines recommend the following criteria for segmentectomy for non-small cell lung cancer (NSCLC): size ≤2 cm, margins ≥2 cm and no lymph node involvement. We sought to further stratify the selection criteria for segmentectomy for small peripheral high-grade tumors. Methods This retrospective database study was conducted using the Surveillance, Epidemiology and End Results (SEER) database. We queried for patients with high-grade (poorly differentiated/undifferentiated) pathological (p)T1a/b peripheral NSCLC (tumor size ≤2 cm), who underwent either lobectomy or segmentectomy between 2004 and 2015. Patients with node-positive disease or those who received any form of induction or adjuvant treatments were excluded. Results A total of 4,332 patients met the inclusion criteria, with 3,977 patients (91.8%) treated with lobectomy and 355 patients (8.2%) who underwent segmentectomy. In a propensity matched pair analysis of 640 patients, lobectomy (n=320) showed significantly improved 5-year survival of 45.9% vs. 33.8% for segmentectomy (n=320), P<0.01. In a multivariate Cox regression analysis, lobectomy was associated with significantly improved survival (HR: 0.84, 95% CI: 0.714–0.989, P=0.036). Interestingly, married status, adenocarcinoma histology, number of lymph nodes sampled were associated with better survival (P<0.05), while advanced age and male gender had worse survival outcomes (P<0.05). Conclusions For small peripheral NSCLC ≤2 cm and high grades of tumor differentiation, lobectomy is associated with better long-term survival outcomes as compared to segmentectomy. Additional data is needed to further stratify various NSCLC histologies with their respective grades to allow for better selection for segmentectomy.

Surgery and invasive diagnostic procedures for benign disease are rare in a large low-dose computed tomography lung cancer screening program. J Thorac Cardiovasc Surg 2020; 161:790-802.e2. [PMID: 33023746 DOI: 10.1016/j.jtcvs.2020.08.109] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Revised: 07/10/2020] [Accepted: 08/02/2020] [Indexed: 12/25/2022]
Abstract
OBJECTIVE Lung cancer screening with low-dose chest computed tomography improves survival. However, concerns about overdiagnosis and unnecessary interventions persist. We reviewed our lung cancer screening program to determine the rate of surgery and invasive procedures for nonmalignant disease. METHODS We reviewed all patients undergoing lung cancer screening from January 2012 to June 2017 with follow-up through January 2019. Patients with suspicious findings (Lung CT Screening Reporting and Data System 4) were referred for further evaluation. RESULTS Of 3280 patients screened, 345 (10.5%) had Lung CT Screening Reporting and Data System 4 findings. A total of 311 patients had complete follow-up, of whom 93 (29.9%) were diagnosed with lung cancer. Eighty-three patients underwent lung surgery (2.5% of screened patients). Forty patients underwent lobectomy (48.2%), 3 patients (3.6%) underwent bilobectomy, and 40 patients (48.2%) underwent sublobar resection. Fourteen patients underwent surgery for benign disease (0.43% of screened patients). Fifty-four patients, 5 with benign disease, had at least 1 invasive diagnostic procedure but never underwent surgery. The incidence of any invasive intervention for nonmalignant disease was 0.95% (31/3280 patients). There were no postprocedural deaths within 60 days. Twenty-five patients (0.76%) underwent stereotactic body radiation therapy; 19 patients (76%) had presumed lung cancer without pretreatment pathologic confirmation. CONCLUSIONS Surgical resection for benign disease occurred in 0.43% of patients undergoing lung cancer screening. The combined incidence of any invasive diagnostic or therapeutic intervention, including surgical resection, for benign disease was only 0.95%. Periprocedural complications were rare. These results indicate that concern over unnecessary interventions is overstated and should not hinder adoption of lung cancer screening. A multidisciplinary team approach, including thoracic surgeons, is critical to maintain an appropriate rate of interventions in lung cancer screening.

Abstract
BACKGROUND Stereotactic body radiation therapy (SBRT) is increasingly being offered for early stage non-small cell lung cancer (NSCLC). We sought to evaluate long-term survival outcomes after lobectomy and SBRT in patients aged 80 years or more with stage I NSCLC. METHODS The National Cancer Database was queried for patients with clinical stage IA and IB (size 40 mm or smaller) NSCLC who underwent SBRT or lobectomy. Only patients with no comorbidities were selected. Number of lymph nodes (LN) examined was used to stratify lobectomy patients into 0 LN, 1 to 6 LN, and 7 or more LN. Propensity score analysis was used to adjust treatment groups. Kaplan-Meier and multivariate Cox regression analysis were used for survival analysis. RESULTS A total of 8964 patients with stage I NSCLC treated with lobectomy were compared with 286 patients who received SBRT. Using propensity matched pairs, lobectomy (7 LN or more) had significantly improved survival as compared with SBRT (median 74 vs 53.2 months, P < .05); however, no survival differences were observed when 0 LN were sampled (median 53.8 vs 52.3 months, P = .88). In multivariate analysis, lobectomy was associated with significantly improved survival (hazard ratio 0.726; 95% confidence interval; 0.580 to 0.910; P = .005). In addition, age, sex, high grade, and tumor size were independent predictors of survival. CONCLUSIONS Among healthy octogenarians with clinical stage I NSCLC who are good surgical candidates, lobectomy offers better survival than SBRT. Adequate LN dissection allows true nodal staging and opportunity for adjuvant treatment when unsuspected nodal metastases are found.

Abstract
Implementation of lung cancer screening and improvements in imaging are expected to increase the proportion of lung cancer diagnosed at an early stage. The standard of care has historically been anatomic lobectomy; however, there is now an array of surgical and non-surgical approaches for management of local disease either in active use or under investigation. By their nature, these new modalities offer a theoretical trade-off of reduced morbidity in exchange for reduced efficacy in the setting of advanced disease. It is therefore critical that patients being considered for these approaches (e.g. surgical segmentectomy and SABR) be accurately staged to maximize the potential for definitive treatment. In this article, we will review current approaches to the staging of patients being considered for segmentectomy or ablation. This will serve as a foundation to highlight important questions deserving further investigation.
