J Surg Res 2024; 300:298-308. [PMID: 38838427 DOI: 10.1016/j.jss.2024.04.041] [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: 04/22/2023] [Revised: 03/24/2024] [Accepted: 04/20/2024] [Indexed: 06/07/2024]
Abstract
INTRODUCTION The recent results of the JCOG 0802 and CALGB 140503 studies suggest that segmentectomy should be considered instead of lobectomy for patients with peripheral <2 cm node-negative non-small cell lung cancer (NSCLC). This study aimed to test this hypothesis in a retrospective analysis of a larger dataset of patients with stage I NSCLC recorded in the Surveillance, Epidemiology, and End Results database. METHODS Patients with all stage I NSCLC (≤4 cm in size) who underwent either segmentectomy or lobectomy from 2000 to 2017 were analyzed. The primary endpoints were overall survival and lung cancer-specific survival, while the secondary endpoints were the 30-day and 90-day mortality. RESULTS Overall, 32,673 patients treated by lobectomy and 2166 patients treated by segmentectomy were included in the initial data collection. After 1:1 propensity score matching (PSM), 2016 patients in each group were enrolled in the final analysis with well-balanced baseline characteristics. After PSM, there was no difference between segmentectomy and lobectomy for all stage IA NSCLC (≤3 cm in size) in both overall survival and lung cancer-specific survival (hazard ratio: 0.87 [0.74-1.02], P value: 0.09 and hazard ratio: 0.81 [0.4-1.03], P value: 0.09, respectively). Furthermore, lobectomy had higher 30-day mortality than segmentectomy: 1.1% versus 2.1%, P value: 0.01. However, this difference was not significant for 90-day mortality, even after PSM (3.9% versus 3.0%, P value: 0.17). CONCLUSIONS We found no evidence to support the use of lobectomy rather than segmentectomy in stage IA NSCLC in terms of either overall or lung cancer-specific long-term survival. The choice of lobectomy may also be detrimental to early postoperative recovery.

Abstract
Lung cancer is the most common cause of cancer death. The mainstay treatment for non-small-cell lung cancer (NSCLC), particularly in the early stages, is surgical resection. Traditionally, lobectomy has been considered the gold-standard technique. Sublobar resection includes segmentectomy and wedge resection. Compared to lobectomy, these procedures have been viewed as a compromise procedure, reserved for those with poor cardiopulmonary function or who are poor surgical candidates for other reasons. However, with the advances in imaging and surgical techniques, the subject of sublobar resection as a curative treatment is being revisited. Many studies have now shown segmentectomy to be equivalent to lobectomy in patients with small (<2.0 cm), peripheral NSCLC. However, there is a mix of evidence when it comes to wedge resection and its suitability as a curative procedure. At this time, until more data can be found, segmentectomy should be considered before wedge resection for patients with early-stage NSCLC.

Abstract
BACKGROUND This study aimed to compare the postoperative quality of life (PQOL) between non-small-cell lung cancer (NSCLC) patients who underwent video-assisted thoracoscopic sublobar resection (subsegment, segment, or wedge) and lobectomy. Meanwhile, we developed a PQOL scale for patients with NSCLC after optimization. METHODS Developing and evaluating the postoperative quality-of-life scale of non-small-cell lung cancer (NSCLC-PQOL) followed by the international principles for developing quality-of-life scale. Therefore, we used the NSCLC-PQOL scale to evaluate the PQOL of patients who underwent different surgeries. RESULTS The overall PQOL of patients who underwent video-assisted thoracoscopic lobectomy and sublobar resection gradually worsened from discharge to 3 months postoperatively and progressively improved from three to 6 months postoperatively. And the sublobar resection group showed better PQOL in chest tightness, breath shortness, breathlessness, cough and expectoration than the lobectomy group, and the differences were statistically significant (P < 0.05). The final version of the NSCLC-PQOL contained three dimensions: "signs-symptoms", "psychological and psychiatric", and "social-life" dimensions. CONCLUSIONS The sublobar resection group showed better PQOL in "chest tightness", "breath shortness", "breathlessness", "cough", and "expectoration" than the lobectomy group. Twenty-two items formed a well-behaved PQOL scale after being validated satisfactorily. The scale was a suitable rating tool for evaluating the NSCLC-PQOL of patients. TRIAL REGISTRATION As this study was a retrospective study and not a clinical trial, we did not register this study in the Chinese Clinical Trial Registry.

Abstract
It is still a matter of debate whether the surgical segmentectomy and lobectomy of lung cancer are comparable in the incidence of perioperative wound complications. An extensive review of the literature through August 2023 was carried out with a critical review of four databases. Following the acceptance and elimination criteria set out in the trial, as well as a qualitative assessment of the literature, this resulted in a review of related research that compared the results of both lobectomy and partial resection in the management of lung cancer. The analysis of the data was performed with the RevMan 5.3 software, and the 95% confidence interval [CI] and odds ratio [OR] were performed with either stationary or random-effect models. It is concluded that the operation time of lobectomy is shorter than that of sectioning in the treatment of segmentectomy (mean difference [MD], -38.62; 95% CI, -41.96, -35.28; p < 0.0001). But the rate of postoperative wound infection (OR, 0.62; 95% CI, 0.18, 2.15; p = 0.45) and intraoperative blood loss (MD, 17.54; 95% CI, -4.19, 39.26; p = 0.11) were not significantly different for them. Thus, for those who have received a pulmonary carcinoma operation, different operative methods might not have an impact on the incidence of postoperative wound infections. The operative procedure appears to have a major impact on the length of the operation in patients.

Abstract
OBJECTIVES Pulmonary segmentectomy (SE) became an increasingly popular method for resection of early-stage lung cancer. This study aims to compare the impact of single SE (SSE), multiple SE (MSE) and lobectomy (LE) on postoperative pulmonary function in patients with NSCLC. METHODS Medical records of a total of 1284 patients who underwent LE (n = 493), SSE (n = 558) and MSE (n = 233) at Shanghai Pulmonary Hospital from January 2013 to October, 2020 were retrospectively analysed. Pulmonary function tests (PFTs) were performed preoperatively and 12 months after surgery. RESULTS SSE was associated with a significantly smaller decline in the PFT values compared to MSE and LE. There was a poor consistency between the observed and expected (O/E) loss of pulmonary function in all study groups (P < 0.05). Both LE and SE resulted in similar O/E ratios of all PFT parameters (P > 0.05). CONCLUSIONS Overall loss of pulmonary function was much greater after LE than after both SSE and MSE. MSE was associated with higher postoperative pulmonary function decline compared to SSE but was still beneficial over LE. Both LE and SE groups had similar PFT loss per segment (P > 0.05).

Abstract
Background and Objectives: The existing literature comparing sublobar and lobar resection in the treatment of stage IA lung cancer highlights the trend and overall need for further evaluation of minimally invasive, parenchymal-sparing techniques. The role of uniportal minimally invasive segmentectomy in the oncological therapy of early-stage non-small cell lung cancer (NSCLC) remains controversial. The aim of this study was to evaluate the clinical and midterm oncological outcomes of patients who underwent uniportal video-assisted anatomical segmentectomy for pathological stage IA lung cancer. Materials and Methods: We retrospectively analyzed all patients with pathological stage IA lung cancer (8th edition UICC) who underwent uniportal minimally invasive anatomical segmentectomy at our institution from January 2015 to December 2018. Results: 85 patients, 54 of whom were men, were included. The median length of hospital stay was 3 days (1.-3. IQR 3-5), whereas 30-day morbidity was 15.3% (13 patients), and the in-hospital mortality rate was 1.2% (1 patient). The 3-year overall survival rate was 87.9% for the total population. It was 90.5% in the IA1 group, 93.3% in the IA2 group, and 70.1% in the IA3 group, respectively. Conclusions: There were satisfactory short-term clinical outcomes with low 30-day morbidity and mortality and promising midterm oncological survival results following uniportal minimally invasive anatomical segmentectomy for pathological stage IA non-small cell lung cancer.

Abstract
Background Lung cancer is one of the cancers with the highest morbidity and mortality. During the last decade, the trends of clinical characteristics, surgical treatments and survival of lung cancer patients in China have remained unclear. Methods All lung cancer patients operated on from 2011 to 2020 were identified in a prospectively maintained database of Sun Yat-sen University Cancer Center. Results A total of 7,800 lung cancer patients were included in this study. Within the past 10 years, the average age at diagnosis of the patients remained stable, the proportion of asymptomatic, female and nonsmoking patients increased, and the average tumor size decreased from 3.766 to 2.300 cm. In addition, the proportion of early stage and adenocarcinoma increased, while that of squamous cell carcinoma decreased. Among the patients, the proportion of patients having video-assisted thoracic surgery increased. More than 80% of the patients underwent lobectomy and systematic nodal dissection over the 10 years. Additionally, both the average postoperative length of stay and 1-, 3-, and 6-month postoperative mortality decreased. Moreover, the 1-, 3-, and 5-year overall survival (OS) rates of all the operable patients increased from 89.8, 73.9, and 63.8% to 99.6, 90.7, and 80.8%, respectively. The 5-year OS rates of the patients with stage I, II, and III lung cancer were 87.6, 79.9, and 59.9%, respectively, which were higher than those in other published data. Conclusion There were significant changes in the clinicopathological characteristics, surgical treatments and survival outcomes of the patients with operable lung cancer from 2011 to 2020.

Abstract
BACKGROUND The incidence of synchronous multiple primary lung cancer (SMPLC) has progressively increased, due to recent advances in imaging. To date, no guidelines defining recommendations for patients' selection and no standard treatment of cases with SMPLC have been defined.The primary aim of this systematic review was to assess survival among patients treated with lobectomy or sublobar resection MPLC. METHODS Comprehensive literature search of Medline, the Cochrane Library, reference lists, and ongoing studies was performed according to a prospectively registered design (PROSPERO: CRD42019115487). All studies published between 1998 and December 2020 that examined treatments with lobectomy compared to sublobar resection were included. Two double-blind investigators independently selected articles.Primary outcomes were to assess the 5-year overall survival (OS) rate among patients treated with lobectomy or sublobar resection and the impact of lymph node status on 5-year OS and 5-year disease-free survival in patients with MPLC. RESULTS The search yielded 424 articles; 4 observational studies met the inclusion criteria and collectively evaluated 298 patients with a mean age ranging from 61.5 to 67 years. A total of 112 patients were treated for bilateral synchronous tumors and 186 patients for unilateral multiple synchronous tumors. All included studies showed that the type of resection, lobectomy or limited resection, had no significant impact on survival. CONCLUSION Limited resection is a valuable treatment option for MPLC. However, the clinical level of evidence of the studies found is low and randomized studies are needed to clarify the extent of resection in MPLC.

Abstract
BACKGROUND Stereotactic ablative radiotherapy (SABR) is recommended as first-choice treatment to inoperable early-stage non-small cell lung cancer (NSCLC). However, it is not widely adopted in developing countries, and its cost-effectiveness is unclear. We aimed to perform a systematic review of full economic evaluations (EE) that compared SABR with other radiotherapy or surgical procedures to assess the results and methodological approach. METHODS The protocol was registered on PROSPERO (CRD42021241640). We included full EE studies with early-stage NSCLC in which one group was submitted to SABR. Studies that were partial EE, included advanced NSCLC or other neoplasm were excluded. We performed the last search on June 2021 in Medline, EMBASE and other databases. The reporting quality were assessed by CHEERS checklist. The main characteristics of each study were tabulated, and the results were presented by a narrative synthesis. RESULTS We included nine studies. Three compared radiotherapy techniques, in which SABR was found to be dominant or cost-effective. Six compared SABR with surgery, and in this group, there was not a unanimous decision. All included only direct healthcare costs but varied about categories included. The parameters used in the model-based studies were highly heterogeneous using mixed data from various sources. The items properly reported varied from 29 to 67%. CONCLUSIONS The studies were all from developed countries and lacked in reporting quality. We recommend that developing countries produce their own studies. More strict alignment to reporting guidelines and use of robust evidence as model parameters are also advised.

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

Front Oncol 2022; 11:784289. [PMID: 35155190 PMCID: PMC8828472 DOI: 10.3389/fonc.2021.784289] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2021] [Accepted: 12/24/2021] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND The efficacy of adjuvant chemotherapy in patients with 8th edition stage IB (tumor size ≤4 cm) non-small cell lung cancer (NSCLC) remains unclear. METHODS We identified 9757 eligible patients (non-chemotherapy group: n=8303; chemotherapy group: n=1454) between 2004 and 2016 from the Surveillance, Epidemiology and End Results (SEER) database. Log-rank test was used to compare overall survival (OS) between the chemotherapy and non-chemotherapy groups. Cox regression model was applied to investigate the independent prognosis factors of all surgically treated stage IB patients, and then the nomogram was constructed. Propensity score matching (PSM) was performed to reduce the confounding bias, and subgroup analyses of the matched cohort were also performed. Finally, we reviewed 184 patients with stage IB NSCLC from July 2008 to December 2016 in Jinling Hospital as a validation cohort, and compared disease-free survival (DFS) and OS between the two groups. RESULTS In the SEER database cohort, adjuvant chemotherapy was associated with improved OS in both unmatched and matched (1417 pairs) cohorts (all P <0.05). The survival benefit (both OS and DFS) was confirmed in the validation cohort (P <0.05). Multivariate analysis showed age, race, sex, marital status, histology, tumor location, tumor size, differentiation, surgical method, lymph nodes (LNs) examined, radiotherapy and chemotherapy were prognostic factors for resected stage IB NSCLC (all P <0.05). The concordance index and calibration curves demonstrated good prediction effect. Subgroup analyses showed patients with the following characteristics benefited from chemotherapy: old age, poor differentiation to undifferentiation, 0-15 LNs examined, visceral pleural invasion (VPI), lobectomy and no radiotherapy (all P <0.05). CONCLUSIONS Adjuvant chemotherapy is associated with improved survival in 8th edition stage IB NSCLC patients, especially in those with old age, poorly differentiated to undifferentiated tumors, 0-15 LNs examined, VPI, lobotomy and no radiotherapy. Further prospective trials are needed to confirm these conclusions. Besides, the nomogram provides relatively accurate prediction for the prognosis of resected stage IB NSCLC patients.

Abstract
Background Stage I non-small-cell lung cancer (NSCLC) can be treated by both ablation and sublobar resection (SR). This meta-analysis was therefore designed to better compare the relative safety and efficacy of these two approaches to treating stage I NSCLC. Materials and methods Relevant studies published through November 2020 in the Cochrane Library, Embase, and PubMed databases were identified for analyses which were conducted with RevMan v5.3. Results In total, 816 potentially relevant articles were identified, of which 8 were ultimately included in the final meta-analysis. Patients in the SR group exhibited a signficantly lower pooled local recurrence (LR) rate (5.0% vs. 25.4%, P < 0.0001), although pooled distant recurrence (DR) rates were similar in both groups (25.7% vs. 23.1%, P = 0.75). The pooled hazard ratio (HR) for overall survival (OS) (HR: 1.23; 95% CI: 1.13–1.33, P < 0.00001), progression-free survival (PFS) (HR: 1.34; 95% CI: 1.15–1.55, P = 0.0002), and cancer-specific survival (HR: 1.39; 95% CI: 1.15–1.70, P = 0.0009) all indicated better survival outcomes among patients that underwent HR treatment, while pooled complication rates were similar in both groups (27.7% vs. 43.8%, P = 0.27). Patients that underwent ablation exhibited significantly shorter pooled post-operative hospitalization relative to those in the SR group (MD: 5.93; 95% CI: 0.78–11.07, P = 0.02). No evidence of publication bias was detected through funnel plot analyses. Conclusions SR treatment of stage I NSCLC patients was associated with a lower LR rate and longer survival as compared to ablation.

Abstract
Complete resection continues to be the gold standard for the treatment of early-stage lung cancer. The landmark Lung Cancer Study Group trial in 1995 established lobectomy as the minimum intervention necessary for the management of early-stage non-small cell lung cancer, as it was associated with lower recurrence and metastasis rates than sublobar resection and lower postoperative morbidity and mortality than pneumonectomy. There is a growing tendency to perform sublobar resection in selected cases, as, depending on factors such as tumor size, histologic subtype, lymph node involvement, and resection margins, it can produce similar oncological results to lobectomy. Alternative treatments such as stereotactic body radiotherapy and radiofrequency ablation can also produce good outcomes in inoperable patients or patients who refuse surgery.

Abstract
OBJECTIVES The role of segmentectomy in early-stage non-small-cell lung cancer (NSCLC) remains a matter of debate. We performed a meta-analysis to evaluate the oncological outcomes following segmentectomy versus lobectomy for stage I, stage IA only and stage IA <2 cm only. METHODS We systematically searched the literature for articles reporting on overall survival (OS), cancer-specific survival (CSS) or recurrence-free survival (RFS). The hazard ratios (HRs) were retrieved and pooled using an inverse variance-weighted approach. RESULTS Twenty-eight studies were included in the analysis. In stage I, segmentectomy was found to be inferior to lobectomy for all 3 outcomes with HR: 1.25 (P = 0.01) for OS, 1.59 (P = 0.02) for CSS and 1.40 (P < 0.001) for RFS. In stage IA, the differences were significant for OS and CSS, though not for RFS with HR: 1.31 (P = 0.04), 1.56 (P = 0.02) and 1.22 (P = 0.11), respectively. In stage IA <2 cm, no significant differences were found between segmentectomy and lobectomy with HR: 1.13 (P = 0.37) for OS, 1.02 (P = 0.95) for CSS and 1.24 (P = 0.11) for RFS. CONCLUSIONS For stages I and IA, lobectomy showed superior results whereas for tumours <2 cm, our study did not find significant differences in oncological outcomes between both groups. These results suggest that segmentectomy might be a valuable alternative to lobectomy for NSCLC in tumours <2 cm.

Abstract
Background Anatomical segmentectomy is an alternative to lobectomy for early-stage lung cancer (LC) or in patients at high risk. The main objective of this study was to compare the morbidity and mortality associated with these two types of pulmonary resection using data from the French National Epithor database. Methods All patients who underwent lobectomy or segmentectomy for early-stage LC from January 1st 2014 to December 31st 2016 were identified in the Epithor database. The primary endpoint was morbidity; the secondary endpoint was postoperative mortality. Propensity score matching was implemented and used to balance groups. The results were reported as odds ratios (OR) and 95% confidence intervals (CI). Results During the study period, 1,604 segmentectomies (9.78%) and 14,786 lobectomies (90.22%) were performed. After matching, the segmentectomy group experienced significantly less atelectasis (OR 0.54; 95% CI: 0.4–0.75, P<0.0001), pneumonia (OR 0.72; 95% CI: 0.55–0.95, P=0.02), prolonged air leaks (OR 0.75; 95% CI: 0.64–0.89, P=0.001) or bronchopleural fistula (OR 0.35; 95% CI: 0.14–0.83, P=0.017), and fewer patients had at least one complication (OR 0.7; 95% CI: 0.62–0.78, P<0.0001). According to the Clavien-Dindo classification, postoperative complications were significantly less severe in the segmentectomy group (OR 0.52; 95% CI: 0.37–0.74, P<0.0001). There was no significant difference in postoperative mortality at 30 days (OR 0.67; 95% CI: 0.38–1.20, P=0.18), 60 days (OR 0.78; 95% CI: 0.42–1.47, P=0.4), or 90 days (OR 0.77; 95% CI: 0.45–1.34, P=0.36). Conclusions Anatomical segmentectomy is an alternative surgical approach that could reduce postoperative morbidity, but it does not appear to affect mortality.

Abstract
OBJECTIVES We performed a systematic review and meta-analysis of outcomes of lobectomy versus sublobar resection in elderly patients (≥65) with stage 1 nonsmall cell lung carcinoma (NSCLC). METHODS We searched for relevant articles using a set of inclusion and exclusion criteria. Meta-analytic techniques were applied. RESULTS Twelve studies (n = 5834) were chosen. Our results indicate that in the elderly, lobectomy for stage 1 NSCLC confers a survival advantage over sublobar resection. Lobectomy patients had a lower risk of death within 5 years and lower odds of local cancer recurrence. Our results show that lobectomy had a better 5-year cancer-specific survival and 5-year disease-free survival that trended toward significance. The sublobar resection group showed better 30-day operative mortality that trended toward significance. Subgroup analysis of stage 1A cancer demonstrated no difference in 5-year overall survival rates. However, for stage 1B tumors 5-year overall survival favored lobectomy. CONCLUSION Lobectomy for stage 1 NSCLC in elderly patients is superior to sublobar resection in terms of survival and cancer recurrence and should be afforded where possible. For stage 1A tumors, sublobar resection is noninferior and may be considered. Further randomized controlled trials in this topic is required.

Abstract
Since the National Lung Screening Trial in 2011 showed a 20% reduction in lung cancer mortality using annual low-dose computed tomography (LDCT), several randomised controlled trials and studies have been started in Europe. These include the Italian lung study (ITALUNG), the Dutch-Belgian lung cancer screening trial (NELSON), the UK lung cancer screening trial (UKLS), the Detection and screening of early lung cancer with novel imaging technology (DANTE), the Danish lung cancer screening trial (DLCST), the German lung cancer screening intervention trial (LUSI), the Multicentric Italian lung detection trial (MILD) and the CT screening for lung cancer study (COSMOS). As a result of the increasing number of screening trials and the growing utilization of LDCT, the high detection of subsolid nodules is an increasingly important clinical problem. In the last few years, several guidelines have been published and providing guidance on the optimal management of subsolid nodules, but many controversies still exist. Follow-up imaging plays an important role in clinical assessment and subsequent management of this particular type of lung nodules, since they can be transient inflammatory lesions, and if persistent they can be both benign lesions or lung cancers of variable clinical behaviour. However, the vast majority of subsolid nodules retain an indolent course over many years. The aim of this review is to present a European perspective in management of screening detected subsolid nodules.

Abstract
Background This study aimed to investigate the prognostic impact of intrapulmonary lymph node (ILN, stations 13–14) dissection on disease‐free survival (DFS) in stage IA non‐small cell lung cancer (NSCLC) patients in order to facilitate a more suitable determination of surgical strategies for early‐stage cases. Methods We retrospectively analyzed 416 patients with pathological stage IA NSCLC from February 2016 to November 2019. The patients were divided into a group with ILN dissection (ILND+ group) and a group without ILN dissection (ILND‐ group). DFS was compared using the Kaplan–Meier method and compared statistically using the log‐rank test before and after propensity score matching (PSM). Subgroup analysis of DFS stratified based on tumor size was also calculated. Results Both before and after PSM, the four‐year DFS of the ILND+ group was greatly increased compared to that of ILND‐ group (90.1% vs. 79.7%, p = 0.003; 95.5% vs. 80.6%, p = 0.003, respectively) and multivariable cox regression analysis revealed ILN dissection was an independent factor favoring DFS in stage IA NSCLC (p = 0.016 and p = 0.015, respectively). Subgroup analysis revealed the four‐year DFS was comparable between the ILN D+ and ILND‐ groups with regard to tumor size ≤1.5 cm (90.6% vs. 92.7%, p = 0.715). However, the ILN D+ group was found to have a better oncological outcome compared with the ILND‐ group with regard to tumor size >1.5 cm (90.0% vs. 73.8%, p = 0.003). Conclusions The prognostic impact of ILN dissection on patients with stage IA NSCLC appears to be significantly influenced by tumor size, and this should be taken into account when choosing the most appropriate therapeutic modality.

Abstract
Background: Previous researches had not proposed any prediction models for occult lymph node metastasis (OLNM). Considering the occurrence of OLNM and the importance of OLNM management, we aimed to develop a nomogram to predict OLNM of patients with lung adenocarcinoma ≤2 cm. Methods: Characteristics of patients with lung adenocarcinoma of ≤2 cm diameter at the Peking Union Medical College Hospital were retrospectively reviewed. Univariate and multivariate logistic regressions were performed. A nomogram model was developed. The concordance index (C-index) and calibration and decision curves were used to evaluate the predictive ability. Results: A total of 473 patients were enrolled, with an OLNM incidence of 7.4%. Four factors were selected as risk factors. The model had a C-index of 0.932. Calibration and decision curves were determined. Conclusion: Patients with pure ground-glass opacity (pGGO) or noninvasive adenocarcinoma have significantly lower risk of OLNM. SUVmax, CEA, micropapillary and solid component were identified as independent risk factors. The nomogram model was effective in predicting OLNM preoperatively.

Abstract
Background To investigate the comparative effectiveness of stereotactic body radiotherapy (SBRT) and sublobar resection (SLR) in patients with stage I non-small cell lung cancer (NSCLC) considered to be high-risk lobectomy patients. Methods From January 2012 to December 2015, patients who underwent SBRT or SLR for clinical stage I NSCLC were examined retrospectively. Propensity score matching (PSM) was performed to reduce selection bias in SBRT and SLR patients. Results Data from 86 SBRT and 79 SLR patients was collected. Median follow-up periods of the SBRT and SLR groups were 32 and 37 months, respectively. Patients treated with SBRT exhibited significantly higher age, higher likelihood of being male, larger tumor diameter, lower forced expiratory volume in 1 second (FEV1), and poorer performance status compared with SLR patients. There were no significant differences between SBRT and SLR patients for 3-year overall survival (OS) (80.3% and 82.3%, P=0.405), cause-specific survival (CSS) (81.3% and 83.4%, P=0.383), and local control (LC) (89.7% and 86.0%, P=0.501). Forty-nine patients were identified from each group after performing PSM. After patients were matched for age, gender, performance status, tumor characteristics and pulmonary function, no significant differences were observed in 3-year OS (85.4% and 73.3%, P=0.649), CSS (87.2% and 74.9%, P=0.637) and LC (95.6% and 82.1%, P=0.055). Prevalence of significant adverse events (grade 3 or worse) was 0% and 10.2% in the matched SBRT and SLR groups (P=0.056), respectively. Conclusions Disease control and survival in the SBRT patients was equivalent to that seen in SLR patients with stage I NSCLC considered high-risk lobectomy candidates. SBRT could therefore be an alternative option to SLR in treating patients with a high operative risk.

Abstract
Background The aim of this study was to evaluate regional postoperative preserved pulmonary function (PPPF) and three‐dimensional (3D) volumetric changes according to the number of resected subsegments and investigate the factors that most affected pre‐/post PPPF. Methods Patients who underwent thoracoscopic lobectomy (n = 73), and segmentectomy (n = 87) were eligible for inclusion in the study. They were classified according to the number of resected subsegments which ranged from 1 to 10. The percentage of pre‐/postoperative forced expiratory volume in 1 s (FEV1) was used for comparison. Furthermore, lung volumetric changes were calculated using 3D computed tomography (CT) volumetry. Results The percentage of pre‐/postoperative EFV1 between 4 and 5–7 and between 5–7 and 10 were significant (p = 0.03 and p < 0.01, respectively), but not between 1–2 to 4 (p = 0.99). The difference between volumetric changes in the left lower lobe of patients with a number of resected subsegments was significant (p < 0.01). On univariate and multivariate analyses, chronic inflammation was significant for decrease in recovery percentages. When the PPPF was compared among resected subsegments, it gradually decreased with an increase in the number of patients without a postoperative procrastination of inflammation (p < 0.01). Conclusions Segmentectomy is feasible and useful for PPPF. Even a relatively large‐volume resection procedure where 5–7 subsegments are resected can preserve pulmonary function. Chronic inflammation was statistically identified as a risk factor for postoperative preserved pulmonary function. Key points

Abstract
Background: Assessing the prognosis of patients with early-stage non-small cell lung cancer (NSCLC) has become a major clinical issue. This study aimed to devise an effective clinical nomogram and heat map for assessing the survival of patients with stage I NSCLC receiving complete resection. Methods: Nomograms were established based on a retrospective study of 654 patients with stage I NSCLC who underwent radical resection at Sun Yat-Sen University Cancer Center between January 2009 and December 2014. The concordance index (C-index) and calibration curve were used to measure the accuracy and discriminative ability of the final nomogram. Heat maps were constructed with prognostic factors and survival probabilities. Survival curves were depicted using the Kaplan–Meier method, and the log-rank test was used to determine significance. Patients were classified into low- and high-risk subgroups using recursive partitioning analysis based on nomogram scores. Results: In univariate and multivariate analyses, the independent factors for overall survival (OS) and disease-free survival (DFS) were age, sex, tumor size, and visceral pleural invasion, which were all selected in the nomogram. The C-indices of the nomogram for predicting OS and DFS were 0.694 [95% confidence interval (CI) 0.651–0.737] and 0.653 (95% CI 0.61–0.696), respectively. The calibration curves for OS and DFS probabilities showed a good agreement between the nomogram prediction and actual observation. A heat map was generated using the above independent factors for OS and DFS. High-risk patients had shorter OS [hazard ratio (HR) = 3.535, 95% CI 2.444–5.113, p < 0.001] and DFS (HR = 2.607, 95% CI 1.922–3.537, p < 0.001) than low-risk patients. Conclusion: We established a prognostic nomogram and heat map that can be useful for evaluating survival in patients with stage I NSCLC after complete resection. The tools resulted in more accurate prediction and may guide clinicians in making treatment decisions.

Abstract
For a patient with stage I or II non-small cell lung cancer (NSCLC) surgical resection remains the treatment of choice on condition that the patient is functionally operable. A complete resection should be obtained. Often lobectomy is feasible by a minimally invasive approach. For patients with compromised cardiopulmonary function stereotactic radiotherapy is an alternative treatment. For patients who are functionally operable, no definite recommendation can be made as no large, randomised studies have been performed with a sufficient number of patients and long-term follow-up. For this reason, it is important to discuss every patient within a multidisciplinary team with participation of thoracic surgeons and radiation oncologists. To provide personalised advice, the primary tumour, its extension, the patient's comorbidities and his respiratory and cardiac function have to be considered.

Abstract
Lung cancer is the most common cause of cancer death in the world. However, recent studies have found that patients with pulmonary ground-glass opacity (GGO) have a better prognosis. Considering its low invasiveness, sublobar resection may be an appropriate treatment of choice. Low-dose computed tomography (CT) is recommended for the high-risk groups of lung cancer. Patients with nonsolid nodule are suggested to take annual low dose CT following-up. For part-solid or solid nodules, the solid component size less or more than 8 mm is the watershed of surgical treatment. Increasing tumor size is a hint of malignancy. Biopsy can be performed for clinically highly suspected malignant nodules. The endobronchial ultrasound biopsy, CT-guide biopsy, or surgical excision are the mainstream for the diagnosis of lung nodules. But for treatment, the sublobar resection is the mainstream of pulmonary GGO. A precise localization technique makes surgeons get enough resection margin and preserve more pulmonary function of the patients. The different localization technique is suitable for different kind nodular position. For patients with pure pulmonary GGO, annual low dose CT checkup is suitable. If the tumor size or solid part of the tumors increased gradually, adequate sublobar resection after tumor localization technique may provide good prognosis and preserve more pulmonary function of the patients.

Abstract
OBJECTIVE Segmentectomy for lung tumors has been performed with either video-assisted thoracoscopic surgery (VATS) or thoracotomy; however, there is a lack of contemporary, multicenter study that compares both approaches. The aim of this study was to compare the 30-day surgical outcomes of VATS versus thoracotomy for segmentectomy using a large national database. METHODS We performed a retrospective analysis of prospectively maintained American College of Surgeons National Surgical Quality Improvement Program database. Patients who underwent segmentectomy for benign or malignant tumors between 2013 and 2017 were included and divided into 2 groups based on whether they received a thoracotomy or VATS approach. All VATS patients were then into 2 subgroups: early (2013 to 2015) and late (2016 to 2017). Propensity-matched analysis was conducted, and the perioperative variables and outcomes were compared. RESULTS A total of 1,785 patients met the inclusion criteria. VATS segmentectomy was associated with shorter hospital stays (3.9 vs 5.8 days, P < 0.001) and higher rates of home discharge (94% vs 89%, P = 0.002) compared to thoracotomy segmentectomy. VATS was also associated with less postoperative pneumonia (2.8% vs 5.8%, P = 0.007), unplanned intubation (1.5% vs 3.5%, P = 0.016), prolonged intubation (0.6% vs 2.7%, P = 0.001), transfusion requirement (1.7% vs 5.8%, P < 0.001), and deep venous thrombosis (0.1% vs 1.1%, P = 0.03). Compared to the earlier VATS group, the late group was associated with less cardiac arrests (0% vs 0.8%, P = 0.025) and shorter hospital stays (3.3 vs 4.2 days, P < 0.001). CONCLUSIONS When compared with thoracotomy, VATS segmentectomy is associated with less postoperative complications and shorter hospital length of stay. VATS segmentectomy has been used more frequently and with improved outcomes.

Abstract
Background: Lobectomy with mediastinal lymph node dissection has always been recognized as the standardized treatment for early-stage non-small-cell lung cancer. However, the feasibility of segmentectomy performed in stage IB non-small-cell lung cancer (NSCLC) patients remains controversial. The present study aims to investigate whether the outcome of stage IB NSCLC patients undergoing segmentectomy was comparable to those who underwent lobectomy. Method: We retrospectively collected data of 11,010 patients with primary stage IB non-small-cell lung cancer from the Surveillance, Epidemiology, and End Results database. Overall survival (OS) and lung cancer-specific survival (LCSS) were assessed among patients who were performed lobectomy or segmentectomy. To further assess the impact of the surgical procedures on patients with different tumor sizes, subgroups stratified by tumor size were analyzed. Results: A total of 11,010 patients who were pathologically confirmed to be stage IB were included, of whom 10,453 received lobectomy and 557 received segmentectomy. Both univariate and multivariate Cox regression analyses showed that the patients receiving lobectomy had better OS [hazards ratio (HR) = 1.197, 95% confidence interval (CI) (1.066, 1.343), P < 0.001] than those receiving segmentectomy. However, multivariate analysis showed that there was no significant difference in LCSS between lobectomy and segmentectomy [HR = 1.172, 95% CI (0.963, 1.427), P = 0.114]. Meanwhile, subgroup analyses showed that lobectomy rather than segmentectomy was associated with better OS [HR = 1.278, 95% CI (1.075, 1.520) P = 0.006] and LCSS [HR = 1.118, 95% CI (1.005, 1.280), P = 0.047] for patients with a tumor size (TS) of ≤ 40 and >30 mm, while for patients with a TS of ≤ 30 mm, lobectomy yielded similar OS [TS ≤ 20 mm: HR = 1.068, 95% CI (0.853, 1.336), P = 0.566; TS > 20 mm and ≤ 30 mm: HR = 1.195, 95% CI (0.961, 1.487), P = 0.109] and LCSS [TS ≤ 20 mm: HR = 1.029, 95% CI: (0.682, 1.552), P = 0.893; TS > 20 and ≤ 30 mm: HR = 1.144, 95% CI (0.795, 1.645), P = 0.469] to that of segmentectomy. Conclusion: Segmentectomy achieved equivalent OS and LCSS in stage IB NSCLC patients with TS ≤ 30 mm compared with lobectomy. Lobectomy showed better OS and LCSS than segmentectomy for patients with a TS of >30 and ≤ 40 mm. Segmentectomy may be acceptable in patients with an older age and a smaller TS.

Abstract
Background Lobectomy has long been regarded as the standard treatment for operable non-small cell lung cancer (NSCLC). Recent studies suggested that segmentectomy could achieve a good prognosis for early-stage NSCLC and might be an alternative to lobectomy in this cohort. Until now, on the issue of comparison between lobectomy and segmentectomy, there remains no published randomized controlled trial (RCT), and all existing evidence is low. Recently, a categorization of lower-level evidence has been proposed, namely, the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The aim of this meta-analysis is to compare the oncologic outcome between lobectomy and segmentectomy in NSCLC with the clinical T1N0M0 stage according to the GRADE system. Methods PubMed, the PMC database, EMBASE, Web of Science, and the Cochrane library were searched prior to May 2019 to identify studies that compared the prognosis between lobectomy and segmentectomy for clinical T1N0M0 NSCLC. The evidence level of the included studies was assessed according to the GRADE system, including level IIA, probably not confounded nonrandomized comparison; level IIB, possibly confounded nonrandomized comparison; and level IIC, probably confounded nonrandomized comparison. The predefined outcomes included overall survival (OS) and disease-free survival (DFS). Univariable and multivariable hazard ratios (HRs) with 95% confidence intervals (95% CI) were pooled using a random-effects model. Results Twelve nonrandomized studies involving 8,072 participants were included. Of these studies, two were classified as IIA level (16.7%), six as IIB level (50.0%), and four as IIC level (33.3%). When crude HRs were included, compared with lobectomy, segmentectomy was associated with shorter OS but comparable DFS in the entire cohort (OS, pooled HR =1.45, 95% CI, 1.23 to 1.67; DFS, pooled HR =1.03, 95% CI, 0.65 to 1.82) and in patients with nodules ≤2 cm (OS, pooled HR =1.55, 95% CI, 1.33 to 1.80; DFS, pooled HR =0.98, 95% CI, 0.55 to 1.77). When adjusted HRs were included, the impact of segmentectomy on OS and DFS was comparable to that of lobectomy in the entire cohort (OS, pooled HR =1.39, 95% CI, 0.92 to 2.10; DFS, pooled HR =0.83, 95% CI, 0.66 to 1.03) and in patients with nodules ≤2 cm (OS, pooled HR =1.61, 95% CI, 0.87 to 3.00; DFS, pooled HR =0.90, 95% CI, 0.63 to 1.27). Conclusions Based on our results, although shorter OS is observed in patients received segmentectomy, it is necessary to wait for more results from RCT to draw a valid conclusion.

Abstract
Introduction Adenosquamous lung cancer (ASC) is a rare type of NSCLC with poor prognosis. There is no consensus on the necessity of adjuvant chemotherapy and the selection of surgical procedures for patients with early stage lung cancer. Few studies have investigated the treatment for early stage ASC. Methods All cases of TNM stage I ASC as per the seventh edition of the American Joint Committee on Cancer staging system were identified from the Surveillance, Epidemiology, and End Results database from 2004 to 2016. The prognostic factors of the primary cohort were identified. Clinical characteristics, first-line treatments, surgical procedures, and survival data, including overall survival and cancer-specific survival, were analyzed. Results A total of 1251 patients were included. The mean age of the patients was 70 years (±9.5 y). Male and white patients accounted for larger proportions. There were 656 and 595 patients with stages IA and IB, respectively. The mean tumor size was 26.2 mm (±10.7 mm). With respect to the treatment, 139 patients who received only chemotherapy had the worst prognosis. Similar outcomes were observed in both the surgery and adjuvant therapy groups. Nevertheless, adjuvant chemotherapy could improve survival outcomes of patients with a tumor size of 4 to 5 cm. Of the 1075 patients who underwent surgery, there were 224 cases of sublobar resection, 834 cases of lobectomy, and 17 cases of extended or sleeve lobectomy. The results revealed that patients who underwent lobectomy had better prognosis. Conclusions Early stage ASC has a poor prognosis. Adjuvant chemotherapy was found to have no considerable benefit in patients with stage I disease (eighth edition). Lobectomy or other radical surgeries are recommended as they can improve overall survival of patients with ASC.

Lymphadenectomy is Unnecessary for Pure Ground-Glass Opacity Pulmonary Nodules. J Clin Med 2020; 9:jcm9030672. [PMID: 32131524 PMCID: PMC7141214 DOI: 10.3390/jcm9030672] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2020] [Revised: 02/25/2020] [Accepted: 02/27/2020] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Lobectomy plus lymph node dissection is the standard treatment of early-stage lung cancer, but the low lymph node metastasis rate with ground-glass opacity (GGO) makes surgeons not perform lymphadenectomy. This study aimed to re-evaluate the lymph node metastasis rate of GGO to help make a clinical judgment. METHODS We performed this retrospective study to enroll patients who received lung cancer surgery from 2011 to 2016. Patient characteristics collected included tumor size, solid part size and lymph node metastasis rate. These patients were categorized into pure GGO and part solid GGO groups to undergo analysis. RESULTS Lymph node metastasis rates were 0%, 3.8% and 6.9% in order of the pure GGO group, the GGO predominant group and the solid predominant group. In the lobectomy patients, the solid predominant group still showed to have the highest lymph node metastasis rate and recurrence rate (8.3% and 10.1%). CONCLUSION It is unnecessary to perform lymphadenectomy for patients with pure GGO in view of the 0% lymph node metastasis rate. The higher lymph node metastasis rate in the patients with the solid predominant group, 6.9%, suggested that surgeons should choose a rational lymphadenectomy method according to their GGO property and clinical judgment.

Abstract
Background This study aims to evaluate the outcomes of sublobar resections in patients with early-stage non-small cell lung cancer and to investigate the factors affecting survival. Methods Medical files of a total of 63 patients (52 males, 11 females; mean age 64 years; range, 39 to 81 years) who underwent sublobar resection for suspected or known early-stage non-small cell lung cancer between January 2001 and August 2013 were retrospectively reviewed. Data including demographic characteristics of the patients, comorbid conditions, smoking status, surgical margin, visceral pleura invasion, distance from surgical margin to tumor, tumor size, pathological N status, cell type, tumor localization, and recurrences were recorded. Results Survival was significantly longer in the patients with negative surgical margin for tumor (R0) than in those with positive margin (R1) (94.1 months vs. 32.2 months, p<0.01). Survival was also significantly longer in the patients without lymphatic invasion (p<0.01). Conclusion In early-stage lung tumors, sublobar resection can be performed, if complete resection is performed. Lymphatic invasion is a negative prognostic factor for survival following sublobar resection.

Abstract
BACKGROUND We aimed to investigate the pattern of regional lymph node (LN) metastasis of early-stage non-small cell lung cancer (NSCLC) to provide novel rationale for surgical choice (lobectomy, segmentectomy, or wedge resection) for these patients. METHODS We retrospectively collected clinical data of patients undergoing lobectomy with systematic mediastinal LN dissection or sampling for cT1N0M0 peripheral NSCLC from January 2015 to December 2018. The regional LN metastasis pattern was analyzed based on tumor size. RESULTS We included a total of 354 patients for analysis. The rate of hilar or intrapulmonary LN metastasis was 13.6%. When stratified by tumor size, NSCLC less than or equal to 1 cm had no hilar or intrapulmonary LN metastasis (0%) while NSCLC greater than 2 cm but less than or equal to 3 cm had a significantly high rate of hilar or intrapulmonary LN metastasis (18.4%) and the rates of hilar, interlobar, and peripheral LN metastasis were also relatively high (5.4%, 5.4%, and 12.2%, respectively). NSCLC greater than 1.5 cm but less than or equal to 2 cm also had relatively high rates of hilar (6.5%) and peripheral (18.3%) LN metastasis, while NSCLC greater than 1 cm but less than or equal to 1.5 cm had significantly low rates of hilar or intrapulmonary (2.5%) and peripheral (2.5%) LN metastasis. Radiographic feature and histology were found to be independent predictors of regional LN metastasis. CONCLUSIONS The pattern of regional LN metastasis in clinical stage IA peripheral NSCLC was significantly influenced by tumor size, which may provide evidence on surgical choice (lobectomy, segmentectomy, or wedge resection) for these early-stage NSCLC patients based on tumor size.

Abstract
Background: Postoperative prognosis of early stage non-small cell lung cancer (NSCLC) undergoing sublobectomy is heterogeneous. Therefore, we sought to construct a novel survival prediction model for stage IA NSCLC ≤2 cm undergoing sublobectomy. Methods: Based on the data from the Surveillance, Epidemiology, and End Results (SEER) program, we successfully determined and incorporated independent prognostic markers to construct the nomogram. Internal validation of the constructed nomogram was conducted through 1,000 bootstrap resamples. The constructed nomogram was further subjected to external validation with an independent cohort of patients from two Chinese institutions. The performance of the survival prediction model was assessed by concordance index, calibration plots, and risk subgroup classification. Results: A total of 3,238 patients from SEER registries (development cohort), as well as 769 patients from two Chinese institutions (validation cohort) was included. Gender, age, size, histologic type, grade, and examined lymph nodes count were identified as significant prognostic parameters. A novel nomogram was developed and externally validated. Concordance index of constructed nomogram was significantly better than that of the current TNM staging system. Calibration plots demonstrated an optimal consistency between the nomogram predicted and actual observed probability of survival. Survival curves of different risk subgroups within respective TNM stage demonstrated significant distinctions. Conclusion: We developed and externally validated a survival prediction model for patients with stage IA NSCLC ≤2 cm undergoing sublobectomy. This novel nomogram outperforms the conventional TNM staging system and could help clinicians in postoperative surveillance and future clinical trial design.

Abstract
BACKGROUND As there is no consensus on the optimal surgery strategy for multiple primary lung cancer (MPLC), we conducted this study to address this issue by comparing the prognosis of MPLC patients underwent different surgical strategies including sublobar resection and the standard resection through a systemic review and meta-analysis. METHODS Relevant literature was obtained from three databases including PubMed, Embase and Web of Science. Inclusion and exclusion criteria were set for the screening of articles to be selected for further conduction of systemic review and meta-analysis. The HRs of OS of the sublobar group compared with standard resection group were extracted directly or calculated indirectly from included researches. RESULTS Ten researches published from 2000 to 2017 were included in this study, with 468 and 445 MPLC cases for the standard resection group and sublobar resection group respectively. The result suggested that OS of MPLC patients underwent sublobar resection (segmentectomy or wedge resection for at least one lesion) was comparable with those underwent standard resection approach (lobectomy or pneumonectomy for all lesions), with HR 1.07, 95% CI 0.67-1.71, p = 0.784. Further analysis found no difference in subgroups of synchronous and metachronous (from second metachronous lesion), different population region and dominant sex type. CONCLUSIONS This study may reveal that sublobar resection is acceptable for patients with MPLC at an early stage, because of the equivalent prognosis to the standard resection and better pulmonary function preservation. Further research is needed to validate these findings.

Abstract
Background The purpose of this study is to explore whether 3D printing has a better clinical value for making a preoperative plan than three-dimensional computed tomography (3D-CT) in thoracoscopic pulmonary segmentectomy. Methods We collected a total of 124 patients' clinical data who underwent thoracoscopic pulmonary segmentectomy from October 2017 to August 2018. According to the preoperative examination, the patients were divided into three groups: general group, 3D-CT group, and 3D printing group. The clinical data of each group were analyzed and compared. Results Compared with the general group, intraoperative blood loss in 3D-CT group and 3D printing group decreased significantly (P<0.05). Operation time in 3D-CT group and 3D printing group was significantly shorter than in the general group (P<0.05). Between 3D-CT group and 3D printing group intraoperative blood loss and operation time had no significant differences (P>0.05). Postoperative chest tube duration and postoperative hospital stay had no significant differences between each group P>0.05). The incidence of postoperative hemoptysis in the general group occurred higher than in the 3D-CT group and 3D printing group, but the differences were not statistically significant (P>0.05). Postoperative complications of pneumonia, atelectasis, and pulmonary air leakage (>6 d) had no significant differences between each group (P>0.05). Conclusions 3D printing and 3D-CT for making a preoperative plan have an equivalent effect in thoracoscopic pulmonary segmentectomy for experienced surgeons. Preoperative simulations using 3D printing for the assessment of pulmonary vessel and bronchi branching patterns is beneficial for the safe and efficient performance of thoracoscopic pulmonary segmentectomy.

Abstract
Purpose Prognostic significance of volumetric 18F-fluorodeoxyglucose (FDG) positron emission tomography/computer tomography (PET/CT) parameters in carbon-ion radiotherapy (C-ion RT) treated stage I non-small cell lung cancer, and need of histology-wise separate cut-off values for risk stratification were assessed. Methods Thirty-nine patients (29 men and 10 women, 71.9 ± 8.3 years) who underwent FDG PET/CT examinations before C-ion RT were retrospectively evaluated. FDG-PET parameters: standardized uptake values (SUVmax, SUVpeak, and SUVmean), metabolic tumor volume (MTV), and total lesion glycolysis (TLG), and clinicopathological variables were assessed for prognosis using Cox proportional hazards regression analysis. Mann-Whitney test compared medians of significant parameters between adenocarcinoma (AC) and squamous cell carcinoma (SCC), and Kaplan-Meier curves were plotted for median-based low- and high-risk groups. Results Median follow-up period was 44.8 months. 1/2/3-year overall survival (OS), progression-free survival (PFS) and local control (LC) rates were 94.9/84.3/70.8, 82.1/69.2/58.4 and 97.3/85.7/82.3%. Multivariate analysis revealed age (hazard ratio, HR: 1.09; 95% confidence interval, CI: 1.0–1.19, p < 0.05) and MTV (HR 4.83, 95% CI 1.21–19.27, p < 0.03) predicted OS, and only MTV predicted PFS (HR 5.3, CI 1.32–21.35, p < 0.02) independently. Compared with AC, SCC had higher MTV (median, 6.625cm3 vs 0.2 cm3, p < 0.01). Single MTV cut-off based on overall cohort was insignificant in SCC for PFS (p > 0.02); separate cut-offs of MTV, 0.2 cm3 for AC (p < 0.03) and 6.625 cm3 for SCC (p < 0.05) were relevant. Conclusion Among all FDG PET/CT parameters, only MTV beared prognostic ability for stage I NSCLC treated with C-ion RT, and its histological variation may need consideration for risk-adapted therapeutic management.

Although lobectomy is well established as the standard surgical procedure for stage IA non-small-cell lung cancer (NSCLC), sublobar resection is increasingly preferred, particularly in intentional segmentectomy for radiologically less-invasive small NSCLC. However, the indication for sublobar resection of radiologically pure solid or solid-dominant NSCLC remains controversial, owing to its invasive pathological characteristics. Therefore, the present meta-analysis was conducted to compare the efficacy of sublobar resection with lobectomy for treating solid-dominant stage IA NSCLC. An electronic search was conducted using four online databases from their dates of inception to April 2017. The hazard ratio (HR) was used as a summary statistic for censored outcomes and the odds ratio (OR) was used as the summary statistic for dichotomous variables. A total of nine studies met the selection criteria, including a total of 2,265 patients (1,728 patients underwent lobectomy, 425 segmentectomy and 112 wedge resection). From the available data, patients treated with a sublobar resection had a higher risk of local recurrence compared with patients treated with lobectomy [OR=1.89; 95% confidence interval (CI), 1.02–3.50; P=0.04]. However, no obvious difference in local recurrence was found in a subgroup analysis of segmentectomy compared with lobectomy (OR=1.19; 95% CI, 0.68–2.10; P=0.61). Sublobar resection was not associated with a significantly negative impact on distant recurrence (OR=1.09; 95% CI, 0.55–2.16; P=0.796). Patients in the sublobar resection group had no significant differences in recurrence-free survival (RFS; HR=1.43; 95% CI, 0.76–2.69; P=0.27) and overall survival (OS; HR=0.96; 95% CI, 0.75–1.23; P=0.77) compared with those in the lobectomy group. In the subgroup analysis of anatomic segmentectomy compared with lobectomy, there was no significant difference in RFS, with mild inter-study heterogeneity. The current meta-analysis suggested that segmentectomy had a comparable oncologic efficacy to lobectomy for solid-dominant stage IA NSCLC. Therefore, segmentectomy may be a feasible alternative in selected cases of solid-dominant stage IA NSCLC. However, these findings should be confirmed by prospective randomized controlled trials in the future.

Abstract
Lobectomy is considered the standard strategy for early-stage non-small cell lung cancer (NSCLC). However, sublobar resection for NSCLC has recently received increased attention. The objective of this study was to compare 5-year survival, recurrence-free survival, postoperative mortality, and postoperative morbidities in patients who received segmentectomy versus those who received lobectomy through a meta-analysis. Sixteen studies were included and the combined hazard ratios or odds ratios were calculated. The results revealed that the 5-year survival rate after segmentectomy was comparable to that of lobectomy for stage IA NSCLC. However, segmentectomy for stage I NSCLC had lower rates of postoperative mortality and morbidities than lobectomy.

Abstract
Management of early stage non-small cell lung cancer (NSCLC) is evolving as the epidemiology of NSCLC has changed due to decreased rates of smoking in the general population, the development of screening programs and advancements in imaging modalities. Surgical technique is also evolving as a result of changes in instrumentation. Segmentectomy for early stage NSCLC has the advantage of preservation of lung function. Video-assisted thoracic surgery (VATS) segmentectomy is a safe option for surgeons already experienced in VATS lobectomy and offers comparable oncological benefit with better quality of life in selected patients. In this article, we will examine the role of segmentectomy and VATS for early stage NSCLC.

Abstract
Background: To investigate the prognostic impact of different types of lymphadenectomy with different extents of tumor resection on the outcomes of stage I non-small-cell lung cancer (NSCLC). Methods: Patients were classified into lobectomy and sublobectomy groups, and then each group was subdivided according to the types of lymphadenectomy. The end points of the study were overall survival (OS) and disease-free survival (DFS). Propensity score matched (PSM) comparative analysis and univariate and multivariate Cox regression analyses were performed. Result: A total of 1,336 patients were included in the current study. Lobectomy was associated with better OS and DFS. In the lobectomy group, lobectomy with bilateral mediastinal lymphadenectomy (BML) was associated with better OS than lobectomy with systematic nodal dissection (SND) or lobe-specific systematic node dissection (L-SND). Lobectomy with SND or L-SND was associated with better OS than lobectomy with systematic nodal sampling (SNS) or selected lymph node biopsy (SLNB). Additionally, lobectomy with BML or SND was associated with better DFS than lobectomy with L-SND or SNS or SLNB. After PSM, compared with lobectomy with SNS or SLNB, lobectomy with SND resulted in more favorable OS and DFS. There was no survival difference between different types of lymphadenectomy for patients who underwent sublobectomy. A multivariable analysis revealed independent associations of lobectomy with BML or SND with better OS and DFS compared with those of lobectomy with SNS or SLNB. Conclusion: This study reveals an association of lobectomy with more systematic and complete lymph node dissection, such as BML or SND, with better prognosis in stage I NSCLC patients.

Abstract
肿瘤肺泡腔内播散(tumor spread through air spaces, STAS)作为一种新的病理侵袭方式,与诸多临床病理因素紧密相关。在肺腺癌中,微乳头和实体型病理亚型与之关系最为密切;针对早期肺腺癌存在STAS,手术类型的治疗上肺叶切除似乎优于亚肺叶切除而获益,可能上调早期肺癌的病理分期;同时,STAS与鳞癌等非小细胞肺癌(non-small cell lung cancer, NSCLC)关系密切。此外,STAS的术中冰冻切片病理检测困难,亦有争议存在。STAS作为肿瘤复发的独立危险因素,亦是提示预后不良的重要因素,本文将STAS的研究现状和进展作一综述。

Abstract
Clinical use of stereotactic body radiation therapy (SBRT) has increased dramatically over the last 2 decades and is the current standard-of-care in cases of inoperable early stage non-small-cell lung cancer. While surgical resection remains the standard-of-care for operable patients, several ongoing clinical trials are investigating the role of SBRT in these operative candidates as well. Taking into consideration the expanding role and utility of SBRT, this paper will: review the historical basis of SBRT; examine landmark trials establishing the framework for the current body of evidence; discuss areas of active and future research; and identify epidemiological trends that are likely to further increase the use of SBRT.

Abstract
Visceral pleural invasion (VPI) has been identified as an adverse prognostic factor for non‐small cell lung cancer (NSCLC). Accurate nodal staging for NSCLC correlates with improved survival, but it is unclear whether tumors with VPI require a more extensive lymph nodes (LNs) dissection to optimize survival. We aimed to evaluate the impact of VPI status on the optimal extent of LNs dissection in stage I NSCLC, using the Surveillance, Epidemiology, and End Results (SEER) database. We identified 9297 surgically treated T1‐2aN0M0 NSCLC patients with at least one examined LNs. Propensity score matching was conducted to balance the baseline clinicopathologic characteristics between the VPI group and non‐VPI group. Log‐rank tests along with Cox proportional hazards regression methods were performed to evaluate the impact of extent of LNs dissection on survival. VPI was correlated with a significant worse survival, but there was no significant difference in survival rate between PL1 and PL2. Patients who underwent sublobectomy had slightly decreased survival than those who underwent lobectomy. Pathologic LNs examination was significantly correlated with survival. Examination of 7‐8 LNs and 14‐16 LNs conferred the lowest hazard ratio for T1‐sized/non‐VPI tumors (stage IA) and T1‐sized/VPI tumors (stage IB), respectively. The optimal extent of LNs dissection varied by VPI status, with T1‐sized/VPI tumors (stage IB) requiring a more extensive LNs dissection than T1‐sized/non‐VPI tumors (stage IA). These results might provide guidelines for surgical procedure in early stage NSCLC.

Abstract
BACKGROUND To investigate the risk and predictors of reintervention (surgery or radiotherapy) after limited resection for lung cancer. METHODS A population-based, all-inclusive study using linked data from the New South Wales Admitted Patient Data Collection and Death Register included all patients undergoing limited resection for lung cancer between July 1, 2002, and March 31, 2014. Univariate and adjusted competing risk analyses were used to estimate the effect of potential factors for risk of reintervention within 6 months and 24 months of the initial surgery. RESULTS The overall 5-year survival for lung cancer patients undergoing limited lung resection was 52% (49% to 54%); for patients aged 70 years or more, the survival rate was 44% (40% to 47%). Reintervention occurred in 6.2% by 6 months and 11.3% by 24 months after the surgery. Younger age, surgery in private hospitals, and fewer comorbidities were independently associated with increased risk of reintervention. Patients who had the surgery performed in high surgical volume hospitals had 49% lower risk of reintervention within the first 6 months (95% confidence interval: 0.30 to 0.85). The effect of hospital surgical volume was attenuated by 24 months (hazard ratio 0.87, 95% confidence interval: 0.60 to 1.28). Patients undergoing reintervention within 6 months or 24 months had a twofold (1.52 to 2.57) and 2.3-fold (1.89 to 2.83) increased risk of death, respectively. CONCLUSIONS The reintervention rate within 6 or 24 months of initial limited lung cancer resection was modest, but there was considerable variation among hospitals. Reintervention was not a benign event and was associated with lower survival in an Australian population.

Abstract
Background Bilateral synchronous multiple primary lung adenocarcinoma (BSMPLA) is a rapidly increasing disease for which timely and accurate treatment is required. We describe our experience which we hope to establish optimal therapeutic options for patients with BSMPLA. Methods This study aimed to explore the feasibility and safety of simultaneous bilateral video-assisted thoracoscopic surgery (VATS) in 56 patients who received histological diagnoses of BSMPLA at our hospital between January 2016 and January 2018. In this retrospective analysis of clinical outcomes, we observed no serious postoperative complications or perioperative death. Results Four and 28 patients respectively underwent bilateral lobectomy and lobectomy with contralateral sublobar resection, whereas the remaining 24 patients underwent bilateral sublobar resection. Sublobar resection means anatomical segmentectomy or wedge resection. The mean postoperative hospital stay duration was 5.39±2.67 days. Postoperative complications comprising persistent air leakage for more than 5 days was observed in 8 (14.2%) of 56 patients. No severe postoperative complications or deaths occurred. Conclusions Our results suggest that simultaneous bilateral VATS is feasible, safe, and reproducible. This therapeutic strategy appears to confer considerable benefits on patients with BSMPLA.

Abstract
随着胸部计算机断层扫描(computed tomography, CT)检查,尤其是低剂量薄层CT筛查项目在中国的广泛开展,越来越多的无症状肺部磨玻璃结节(ground-glass nodules, GGNs)被发现。虽然国内及国际上已发布了一系列针对肺部GGNs的指南,但是这些指南的撰写者多来自呼吸、肿瘤及影像专业,可能缺乏对现代微创胸外科的充分认识,造成外科手术在肺部GGNs诊治中的作用不明确,甚至被低估;而且,肺部肿瘤相关的各学科对于早期肺癌,尤其是浸润前病变的处理也缺乏统一规范。因此,基于国内外现有文献及上海市肺科医院多年积累的经验,上海市肺科医院撰写了此诊疗共识。本共识推荐对于疑似肺腺癌的GGNs进行多学科评估,依据诊断,选择合理的处置方式。对于疑似原位腺癌,推荐进行胸部薄层CT随访,或在特定情况下进行不超过肺段切除的限制性肺切除;对于疑似微浸润腺癌,推荐进行限制性肺切除或肺叶切除;对于疑似浸润性腺癌,建议依据病灶是否含有磨玻璃成分、位置、大小、个数及患者躯体情况选择合理的手术方式;而肺多发结节的处理原则推荐为主病灶优先,兼顾次要病灶,综合选择治疗方案。
