Outcomes following minimally invasive approaches vs. open extended lobectomy for non-small cell lung cancer: a propensity-matched analysis of the National Cancer Database. Transl Lung Cancer Res 2024; 13:334-344. [PMID: 38496690 PMCID: PMC10938095 DOI: 10.21037/tlcr-24-37] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Accepted: 02/18/2024] [Indexed: 03/19/2024]
Abstract
Background Traditional thoracotomy, an invasive surgical procedure, has been the standard approach for extended lobectomy in treating non-small cell lung cancer (NSCLC). However, minimally invasive surgery (MIS) has gained traction with advancements in surgical techniques. Despite this, the outcomes of extended lobectomy via a minimally invasive approach remain largely uncharted. Using the comprehensive National Cancer Database (NCDB), our research aimed to clarify the safety, feasibility, and efficacy of minimally invasive extended lobectomy in patients diagnosed with NSCLC. Methods Our study encompassed a selection of patients with NSCLC who underwent extended lobectomy (defined as lobectomy or bilobectomy with chest wall, diaphragm or pericardial resection) between 2010 and 2014. Through propensity score matching (PSM), we ensured a balanced comparison between patients who underwent MIS and those who opted for the traditional open extended lobectomy. Both univariate and multivariate analyses were employed to discern whether the surgical approach had any significant impact on the prognosis of patients undergoing this specific procedure. Results Before PSM, our dataset included 3,934 patients. After 1:2 PSM, the MIS group included 683 cases, while the open group included 1,317 cases. One notable finding was the reduced average postoperative hospital stay for the MIS group at 7.15 days compared to the open group at 8.40 days (P<0.001). Furthermore, the 5-year survival rate was similar, with the MIS group at 53.1% and the open group at 51.3% (P=0.683). Conclusions The results of our study suggest that MIS for extended lobectomy not only is safe and feasible but also is oncologically effective. However, it is imperative to note that these encouraging findings necessitate further validation through prospective studies to ascertain the full scope of benefits and potential risks associated with MIS.

Comprehensive value implications of surgeon volume for lung cancer surgery: Use of an analytic framework within a regional health system. JTCVS OPEN 2024; 17:286-294. [PMID: 38420536 PMCID: PMC10897681 DOI: 10.1016/j.xjon.2023.11.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 11/08/2023] [Accepted: 11/12/2023] [Indexed: 03/02/2024]
Abstract
Objective We used a framework to assess the value implications of thoracic surgeon operative volume within an 8-hospital health system. Methods Surgical cases for non-small cell lung cancer were assessed from March 2015 to March 2021. High-volume (HV) surgeons performed >25 pulmonary resections annually. Metrics include length of stay, infection rates, 30-day readmission, in-hospital mortality, median 30-day charges and direct costs, and 3-year recurrence-free and overall survival. Multivariate regression-based propensity scores matched patients between groups. Metrics were graphed on radar charts to conceptualize total value. Results All 638 lung resections were performed by 12 surgeons across 6 hospitals. Two HV surgeons performed 51% (n = 324) of operations, and 10 low-volume surgeons performed 49% (n = 314). Median follow-up was 28.8 months (14.0-42.3 months). Lobectomy was performed in 71% (n = 450) of cases. HV surgeons performed more segmentectomies (33% [n = 107] vs 3% [n = 8]; P < .001). Patients of HV surgeons had a lower length of stay (3 [2-4] vs 5 [3-7]; P < .001) and infection rates (0.6% [n = 1] vs 4% [n = 7]; P = .03). Low-volume and HV surgeons had similar 30-day readmission rates (14% [n = 23] vs 7% [n = 12]; P = .12), in-hospital mortality (0% [n = 0] vs 0.6% [n = 1]; P = .33), and oncologic outcomes; 3-year recurrence-free survival was 95% versus 91%; P = .44, and 3-year overall survival was 94% versus 90%; P = 0. Charges were reduced by 28%, and direct costs were reduced by 23% (both P < .001) in the HV cohort. Conclusions HV surgeons provide comprehensive value across a health system. This multidomain framework can be used to help drive oncologic care decisions within a health system.

Abstract
OBJECTIVE Pain requiring opioid use remains an issue even with minimally invasive thoracic surgery. The objective of this study was to investigate the effectiveness of intercostal nerve cryoablation (CRYO) for pain control in adult patients undergoing pulmonary resection. METHODS A retrospective analysis of patients undergoing pulmonary resection by uniportal video-assisted thoracic (uVATS) approach was undertaken. Patients treated with our usual pain regimen (STANDARD) were compared with those who additionally received CRYO. STANDARD includes intercostal bupivacaine, patient-controlled analgesia (24 h), ketorolac (48 to 72 h), and tramadol. Intraoperative CRYO was performed on 5 intercostal levels. The primary aim was to compare pain scores (range, 0 to 10) and morphine equivalent dosages (MED). Secondary outcomes included length of stay, chest tube duration, presence of an air leak, and adverse events. A p value <0.05 was considered significant. RESULTS There were 49 patients (34 female, 15 male). The median age was 74 (37 to 90) years. Procedures included lobectomy (n = 32), segmentectomy (n = 7), and wedge resections (n = 10). There were 23 (46.9%) CRYO and 26 (53.1%) STANDARD patients. Baseline characteristics were similar. Mean length of stay (2.9 vs 3.5 days), chest tube duration (2.2 vs 1.8 days), and adverse events (9 of 23 vs 7 of 26) were similar. There were no complications attributable to CRYO. Pain scores were not significantly different on postoperative days (POD) 1 to 4. MED was significantly reduced after CRYO on POD 1 (5 vs 47.24), POD 2 (10.93 vs 25.04), POD 3 (8.13 vs 21.7), and POD 4 (7.08 vs 19.17). CONCLUSIONS CRYO can be performed safely during pulmonary resection and can decrease in-hospital opioid use. The results from this retrospective study will need to be validated in future prospective studies.

The effect of enhanced recovery after minimally invasive esophagectomy: a randomized controlled trial. Surg Endosc 2022; 36:9113-9122. [PMID: 35773604 PMCID: PMC9652161 DOI: 10.1007/s00464-022-09385-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2022] [Accepted: 06/06/2022] [Indexed: 01/06/2023]
Abstract
BACKGROUND The purpose of this randomized controlled trial was to determine if enhanced recovery after surgery (ERAS) would improve outcomes for three-stage minimally invasive esophagectomy (MIE). METHODS Patients with esophageal cancer undergoing MIE between March 2016 and August 2018 were consecutively enrolled, and were randomly divided into 2 groups: ERAS+group that received a guideline-based ERAS protocol, and ERAS- group that received standard care. The primary endpoint was morbidity after MIE. The secondary endpoints were the length of stay (LOS) and time to ambulation after the surgery. The perioperative results including the Surgical Apgar Score (SAS) and Visualized Analgesia Score (VAS) were also collected and compared. RESULTS A total of 60 patients in the ERAS+ group and 58 patients in the ERAS- group were included. Postoperatively, lower morbidity and pulmonary complication rate were recorded in the ERAS+ group (33.3% vs. 51.7%; p = 0.04, 16.7% vs. 32.8%; p = 0.04), while the incidence of anastomotic leakage remained comparable (11.7% vs. 15.5%; p = 0.54). There was an earlier ambulation (3 [2-3] days vs. 3 [3-4] days, p = 0.001), but comparable LOS (10 [9-11.25] days vs. 10 [9-13] days; p = 0.165) recorded in ERAS+ group. The ERAS protocol led to close scores in both SAS (7.80 ± 1.03 vs. 8.07 ± 0.89, p = 0.21) and VAS (1.74 ± 0.85 vs. 1.78 ± 1.06, p = 0.84). CONCLUSIONS Implementation of an ERAS protocol for patients undergoing MIE resulted in earlier ambulation and lower pulmonary complications, without a change in anastomotic leakage or length of hospital stay. Further studies on minimizing leakage should be addressed in ERAS for MIE.

Abstract
PURPOSE This paper aims to present the results of a series of several Brazilian institutions that have been carrying out lung cancer screening (LCS). MATERIALS AND METHODS This is a retrospective, cohort study, with follow-up of individuals of both sexes, with a heavy smoking history, who participated in LCS programs between December 2013 and January 2021 in six Brazilian institutions located in the states of São Paulo, Rio Grande do Sul, and Bahia. RESULTS Three thousand four hundred seventy individuals were included, of which 59.8% were male (n = 2,074) and 50.6% were current smokers (n = 1,758), with 60.7 years (standard deviation 8.8 years). Lung-RADS 4 was observed in 233 (6.7%) patients. Biopsy was indicated by minimally invasive methods in 122 patients (3.5%). Two patients who demonstrated false-negative biopsies and lung cancer were diagnosed in follow-up. Diagnosis of lung cancer was observed in 74 patients (prevalence rate of 2.1%), with 52 (70.3%) in stage I or II. Granulomatous disease was found in 20 patients. There were no statistical differences in the incidence of lung cancer, biopsies, granulomatous disease, and Lung-RADS 4 nodules between public and private patients. CONCLUSION There are still many challenges and obstacles in the implementation of LCS in developing countries; however, our multi-institutional data were possible to obtain satisfactory results in these scenarios and to achieve similar results to the main international studies. Granulomatous diseases did not increase the number of lung biopsies. The authors hope that it could stimulate the creation of organized screening programs in regions still endemic for tuberculosis and other granulomatous diseases. Challenges still remaining for lung cancer screening. Multi institutional BRELT2 reported good results in Brazil![]()

Pathological complete response after neoadjuvant treatment determines survival in esophageal squamous cell carcinoma patients (NEOCRTEC5010). ANNALS OF TRANSLATIONAL MEDICINE 2021; 9:1516. [PMID: 34790722 PMCID: PMC8576689 DOI: 10.21037/atm-21-3331] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Accepted: 08/17/2021] [Indexed: 02/05/2023]
Abstract
BACKGROUND Few studies have exclusively investigated the value of pathological complete response (pCR), in esophageal squamous cell carcinoma (ESCC) patients, although it is a clinically significant parameter to evaluate the impact of neoadjuvant chemoradiotherapy (nCRT) on treatment outcome after surgery. The aim of our study was to explore the relationship between pCR after nCRT and survival among patients with local ESCC. METHODS All patients receiving nCRT followed by surgery in NEOCRTEC5010-trial (NCT01216527) were included. Non-pCR patients were classified into three subgroups: ypTanyN0M0, ypT0NanyM0 and ypTanyNanyM0. The Kaplan-Meier method with log-rank test was employed to evaluate disease-free survival (DFS) and overall survival (OS). Multivariate regression analysis was performed using a Cox proportional hazards model to identify clinicopathological parameters associated with pCR. RESULTS Among the 185 patients included, 80 (43.2%) achieved pCR after nCRT. The mean survival time of the pCR group was significantly longer than that of the non-pCR group (92.6 vs. 69.2 months; HR, 2.70; 95% CI: 1.48-4.92; P=0.001). The 5-year OS and DFS of the pCR group were 79.3% and 77% respectively, compared to 54.8% and 51.2%, respectively, in the non-pCR group. The results showed that the OS and DFS of the ypTanyN0M0 group were better than those of the ypT0NanyM0 group and the ypTanyNanyM0 group. We also found that the number of dissected lymph nodes and pCR were independent risk factors for DFS and OS rates. CONCLUSIONS pCR after nCRT is an important prognostic indicator of OS and DFS in patients with ESCC. In addition, lymph-node status could represent an important parameter in the prognostic evaluation of esophageal cancer patients.

Abstract
Introduction Vascular impingement of the esophagus is a rare cause of dysphagia, and is most commonly due to aortic arch anomalies such as arterial lusoria. Dysphagia resultant from venous compression is even further less likely. Presentation of case We present a highly unusual case of dysphagia secondary to a large aneurysm of the azygous vein near its confluence with the superior vena cava, which was managed with endovascular modalities. Despite initial treatment success, patient reported some intermittent solid food dysphagia, and was also found to have esophagogastric junction outflow obstruction (EGJOO) on high resolution impedance manometry (HRIM) which was successfully managed with surgical myotomy and partial fundoplication. Discussion The azygos vein has an intimate anatomic relationship with the esophagus as it traverses the posterior mediastinum. Because of this anatomic association, the azygos vein may present a point of esophageal obstruction in the setting of significant pathology. Conclusion This case highlights the possibility of multifactorial causes of dysphagia, and that HRIM is a key aspect of this workup. Additionally we discuss the pertinent anatomy, diagnosis, and treatments for azygos vein aneurysm and EGJOO. Vascular impingement of the esophagus is a rare cause of dysphagia. This type of dysphagia is most commonly due to aortic arch anomalies such as arterial lusoria. The azygos vein may present a point of esophageal obstruction in the setting of significant pathology. Endovascular therapy in selected patients can provide resolution of dysphagia in patients with azygos vein aneurysm. There is possibility of multifactorial causes of dysphagia, and high resolution manometry is a key aspect of this workup.

Abstract
Background A specific risk-stratification tool is needed to facilitate safe and cost-effective approaches to the prophylaxis of acute pulmonary thromboembolism (PTE) in lung cancer surgery patients. This study aimed to develop and validate a simple nomogram model for the prediction of PTE after lung cancer surgery using readily obtainable clinical characteristics. Methods A total of 14,427 consecutive adult patients who underwent lung cancer surgery between January 2015 and July 2018 in our institution were retrospectively reviewed. Included in the cohort were 136 patients who developed PTE and 544 non-PTE patients. The patients were randomly divided into the derivation group (70%, 95 PTE patients and 380 non-PTE patients) and the validation group (30%, 41 PTE patients and 164 non-PTE patients). A nomogram model was developed based on the results of multivariate logistic analysis in the derivation group. The cut-off values were defined using Youden's index. The prognostic accuracy was measured by area under the curve (AUC) values. Results In the derivation group, multivariate logistic analysis was carried out to evaluate the risk score. The risk assessment model contained five variables: age [95% confidence interval (CI): 1.008-1.083, P=0.016], body mass index (95% CI: 1.077-1.319, P=0.001), operation time (95% CI: 1.002-1.014, P=0.008), the serum level of cancer antigen 15-3 (CA15-3) before surgery (95% CI: 1.019-1.111, P=0.005), and the abnormal results of compression venous ultrasonography before surgery (95% CI: 2.819-18.838, P<0.001). All of them were independent risk factors of PTE. To simplify the risk assessment model, a nomogram model was established, which showed a good predictive performance in the derivation group (AUC 0.792, 95% CI: 0.734-0.853) and in the validation group (AUC 0.813, 95% CI: 0.737-0.890). Conclusions A high-performance nomogram was established on the risk factors for PTE in patients undergoing lung cancer surgery. The nomogram could be used to provide an individual risk assessment and guide prophylaxis decisions for patients. Further external validation of the model is needed in lung cancer surgery patients in other clinical centers.

Abstract
BACKGROUND Esophagectomy is a pivotal curative modality for localized esophageal or esophagogastric junction cancer (EC or EJC). Postoperative anastomotic leakage (AL) remains problematic. The use of fibrin sealant (FS) may improve the strength of esophageal anastomosis and reduce the incidence of AL.
AIM To assess the efficacy and safety of applying FS to prevent AL in patients with EC or EJC.
METHODS In this single-arm, phase II trial (Clinicaltrial.gov identifier: NCT03529266), we recruited patients aged 18-80 years with resectable EC or EJC clinically staged as T1-4aN0-3M0. An open or minimally invasive McKeown esophagectomy was performed with a circular stapled anastomosis. After performing the anastomosis, 2.5 mL of porcine FS was applied circumferentially. The primary endpoint was the proportion of patients with AL within 3 mo.
RESULTS From June 4, 2018, to December 29, 2018, 57 patients were enrolled. At the data cutoff date (June 30, 2019), three (5.3%) of the 57 patients had developed AL, including two (3.5%) with esophagogastric AL and one (1.8%) with gastric fistula. The incidence of anastomotic stricture and other major postoperative complications was 1.8% and 17.5%, respectively. The median time needed to resume oral feeding after operation was 8 d (Interquartile range: 7.0-9.0 d). No adverse events related to FS were recorded. No deaths occurred within 90 d after surgery.
CONCLUSION Perioperative sealing with porcine FS appears safe and may prevent AL after esophagectomy in patients with resectable EC or EJC. Further phase III studies are warranted.

Abstract
OBJECTIVE To assess the safety and local recurrence-free survival in patients after cryoablation for treatment of pulmonary metastases. METHODS This multicenter, prospective, single-arm, phase 2 study included 128 patients with 224 lung metastases treated with percutaneous cryoablation, with 12 and 24 months of follow-up. The patients were enrolled on the basis of the outlined key inclusion criteria, which include one to six metastases from extrapulmonary cancers with a maximal diameter of 3.5 cm. Time to progression of the index tumor(s), metastatic disease, and overall survival rates were estimated using the Kaplan-Meier method. Complications were captured for 30 days after the procedure, and changes in performance status and quality of life were also evaluated. RESULTS Median size of metastases was 1.0 plus or minus 0.6 cm (0.2-4.5) with a median number of tumors of 1.0 plus or minus 1.2 cm (one to six). Local recurrence-free response (local tumor efficacy) of the treated tumor was 172 of 202 (85.1%) at 12 months and 139 of 180 (77.2%) at 24 months after the initial treatment. After a second cryoablation treatment for recurrent tumor, secondary local recurrence-free response (local tumor efficacy) was 184 of 202 (91.1%) at 12 months and 152 of 180 (84.4%) at 24 months. Kaplan-Meier estimates of 12- and 24-month overall survival rates were 97.6% (95% confidence interval: 92.6-99.2) and 86.6% (95% confidence interval: 78.7-91.7), respectively. Rate of pneumothorax that required pleural catheter placement was 26% (44/169). There were eight grade 3 complication events in 169 procedures (4.7%) and one (0.6%) grade 4 event. CONCLUSION Percutaneous cryoablation is a safe and effective treatment for pulmonary metastases.

Abstract
BACKGROUND There is a paucity of prognostic factors for patients with stage I non-small cell lung cancer (NSCLC) undergoing operations. We investigated the prognostic role of preoperative complete blood count values in patients with stage I NSCLC patients undergoing operations. METHODS A retrospective medical record review was performed of patients who underwent operations for stage I NSCLC between 2000 and 2015. Patients who died within 30 days of the operations were excluded. The primary end point was recurrence. Preoperative complete blood count values were analyzed, and a median value was used as the cutoff. Statistical analysis used χ2 and t tests along with univariate and multivariate analyses by Cox regression modeling. RESULTS The study included 103 patients. A high lymphocyte count was significantly associated with recurrence (5-year recurrence-free survival [RFS] of 69.8% for high vs 95.7% for low, P = .003), as well as high platelet (5-year RFS of 72.0% for high vs 91.8% for low, P = .02). Independent prognostic factors on multivariate analysis were high lymphocyte (hazard ratio [HR], 7.27; P = .005) and platelet counts (HR, 7.49; P = .003) as well as tumor (HR, 5.40; P = .008) and treatment characteristics (HR, 4.59; P = .01). Among patients with pT1 lesions, high lymphocyte (HR, 8.41; P = .03) and high platelet counts (HR, 19.78; P = .004) remained independent prognostic factors. Neither NLR nor PLR were significantly associated with recurrence. CONCLUSIONS In patients with pathologic stage I NSCLC undergoing surgical resection, the preoperative blood count from peripheral blood may provide prognostic value. Of significance, in patients with pT1 N0 NSCLC, high lymphocyte count and high platelet count were associated with higher recurrence.

Abstract
Abstract
OBJECTIVES
Our goal was to report the results of the first consensus paper among international experts in uniportal video-assisted thoracoscopic surgery (UniVATS) lobectomy obtained through a Delphi process, the objective of which was to define and standardize the main procedural steps, optimize its indications and perioperative management and identify elements to assist in future training.
METHODS
The 40 members of the working group were convened and organized on a voluntary basis by the Uniportal VATS Interest Group (UVIG) of the European Society of Thoracic Surgeons (ESTS). An e-consensus finding exercise using the Delphi method was applied to require 75% agreement for reaching consensus on each question. Repeated iterations of anonymous voting continued for 3 rounds.
RESULTS
Overall, 31 international experts from 18 countries completed all 3 rounds of questionnaires. Although a technical quorum was not achieved, most of the responders agreed that the maximum size of a UniVATS incision should be ≤4 cm. Agreement was reached on many points outlining the currently accepted definition of a UniVATS lobectomy, its indications and contraindications, perioperative clinical management and recommendations for training and future research directions.
CONCLUSIONS
The UVIG Consensus Report stated that UniVATS offers a valid alternative to standard VATS techniques. Only longer follow-up and randomized controlled studies will predict whether UniVATS represents a valid alternative approach to multiport VATS for major lung resections or whether it should be performed only in selected cases and by selected centres. The next step for the ESTS UVIG is the establishment of a UniVATS section inside the ESTS databases.

Abstract
Objective Video-assisted thoracic surgery (VATS) lobectomy was introduced over 25 years ago. More recently, the technique has been modified from a multiport video-assisted thoracic surgery (mVATS) to uniportal (uVATS) and robotic (rVATS), with proponents for each approach. Additionally most lobectomies are still performed using an open approach. We sought to provide evidence-based recommendations to help define the optimal surgical approach to lobectomy for early stage non-small cell lung cancer. Methods Systematic review and meta-analysis of articles searched without limits from January 2000 to January 2018 comparing open, mVATS, uVATS, and rVATS using sources Medline, Embase, and Cochrane Library were considered for inclusion. Articles were individually scrutinized by ISMICS consensus conference members, and evidence-based statements were created and consensus processes were used to determine the ensuing recommendations. The ACC/AHA Clinical Practice Guideline Recommendation Classification system was used to assess the overall quality of evidence and the strength of recommendations. Results and recommendations One hundred and forty-five studies met the predefined inclusion criteria and were included in the meta-analysis. Comparisons were analyzed between VATS and open, and between different VATS approaches looking at oncological outcomes (survival, recurrence, lymph node evaluation), safety (adverse events), function (pain, quality of life, pulmonary function), and cost-effectiveness. Fifteen statements addressing these areas achieved consensus. The highest level of evidence suggested that mVATS is preferable to open lobectomy with lower adverse events (36% versus 42%; 88,460 patients) and less pain (IIa recommendation). Our meta-analysis suggested that overall survival was better (IIb) with mVATS compared with open (71.5% versus 66.7% 5-years; 16,200 patients). Different VATS approaches were similar for most outcomes, although uVATS may be associated with less pain and analgesic requirements (IIb). Conclusions This meta-analysis supports the role of VATS lobectomy for non-small cell lung cancer. Apart from potentially less pain and analgesic requirement with uVATS, different minimally invasive surgical approaches appear to have similar outcomes.

Abstract
OBJECTIVE To determine if induction chemotherapy with concurrent high-dose radiation followed by resection is associated with improved survival in patients with nonsuperior sulcus lung cancer with chest wall invasion. METHODS We performed a retrospective review of clinical T3 (chest wall invasion) N0/N1 patients with non-small cell lung cancer who underwent surgical resection between January 1, 1992, and January 31, 2017. Exclusion criteria included superior sulcus tumors and resection performed for palliation/recurrence. Patients undergoing induction chemoradiation followed by surgical resection were compared to those undergoing resection first or those receiving induction radiation followed by resection. Overall survival was calculated using the Kaplan-Meier method. RESULTS Thirty-four patients were included in the analysis, with 5-year overall survival (OS) of 30%. By clinical stage, 31 (91%) were IIB (T3N0) and 3 (9%) were IIIA (T3N1). Sixteen patients (47%) received induction chemoradiation before surgery. Of the remaining 18 patients, 5 (15%) received induction radiation followed by surgery, and 13 (38%) underwent surgery as the first treatment. Three patients belonging to the group not receiving induction chemoradiation died within 30 days after surgery and were excluded from survival analysis. In the remaining 31 patients, induction chemoradiation was associated with improved 5-year OS (53% for induction chemoradiation vs 7% for others; P<0.01). Disease recurrence was evident in 9 cases, 2 (12.5%) in the induction chemoradiation group and 7 (46.6%) in the others (median disease-free time 103.0 months for induction chemoradiation group vs 8.0 months for others; P<0.01). CONCLUSION In patients with nonsuperior sulcus lung cancer with chest wall invasion, induction chemoradiation therapy followed by resection is associated with improved OS.

Abstract
Enhanced recovery after surgery (ERAS) protocols aim to improve operative outcomes by focusing on perioperative care, including early mobilization, limitation of narcotics, and maintenance of fluid balance. We implemented a T-ERAAS (Thoracic-Early Recovery with Ambulation After Surgery) protocol which focused on early ambulation, with the rationale that a patient's mobility may be a reproducible and measurable metric for their overall status-pain control, respiratory function, cardiac function, and patient satisfaction. We set a benchmark distance of 250 feet for our early ambulation goal and redefined "early" as within the first hour post extubation. We describe some of the major aspects to our program as well as some of the challenges and successes during our 8-year experience following the implementation of this program.

Abstract
Purpose The efficacy of neoadjuvant chemoradiotherapy (NCRT) plus surgery for locally advanced esophageal squamous cell carcinoma (ESCC) remains controversial. In this trial, we compared the survival and safety of NCRT plus surgery with surgery alone in patients with locally advanced ESCC. Patients and Methods From June 2007 to December 2014, 451 patients with potentially resectable thoracic ESCC, clinically staged as T1-4N1M0/T4N0M0, were randomly allocated to NCRT plus surgery (group CRT; n = 224) and surgery alone (group S; n = 227). In group CRT, patients received vinorelbine 25 mg/m2 intravenously (IV) on days 1 and 8 and cisplatin 75 mg/m2 IV day 1, or 25 mg/m2 IV on days 1 to 4 every 3 weeks for two cycles, with a total concurrent radiation dose of 40.0 Gy administered in 20 fractions of 2.0 Gy on 5 days per week. In both groups, patients underwent McKeown or Ivor Lewis esophagectomy. The primary end point was overall survival. Results The pathologic complete response rate was 43.2% in group CRT. Compared with group S, group CRT had a higher R0 resection rate (98.4% v 91.2%; P = .002), a better median overall survival (100.1 months v 66.5 months; hazard ratio, 0.71; 95% CI, 0.53 to 0.96; P = .025), and a prolonged disease-free survival (100.1 months v 41.7 months; hazard ratio, 0.58; 95% CI, 0.43 to 0.78; P < .001). Leukopenia (48.9%) and neutropenia (45.7%) were the most common grade 3 or 4 adverse events during chemoradiotherapy. Incidences of postoperative complications were similar between groups, with the exception of arrhythmia (group CRT: 13% v group S: 4.0%; P = .001). Peritreatment mortality was 2.2% in group CRT versus 0.4% in group S ( P = .212). Conclusion This trial shows that NCRT plus surgery improves survival over surgery alone among patients with locally advanced ESCC, with acceptable and manageable adverse events.

Abstract
Background Surgical resection is the most effective curative therapy for non-small cell lung cancer (NSCLC). However, many patients are unable to tolerate resection secondary to poor reserve or comorbid disease. Radiofrequency ablation (RFA) and microwave ablation (MWA) are methods of percutaneous thermal ablation that can be used to treat medically inoperable patients with NSCLC. We present long-term outcomes following thermal ablation of stage IA NSCLC from a single center. Methods Patients with stage IA NSCLC and factors precluding resection who underwent RFA or MWA from July 2005 to September 2009 were studied. CT and PET-CT scans were performed at 3 and 6 month intervals, respectively, for first 24 months of follow-up. Factors associated with local progression (LP) and overall survival (OS) were analyzed. Results Twenty-one patients underwent 21 RFA and 4 MWA for a total of 25 ablations. Fifteen patients had T1a and six patients had T1b tumors. Mean follow-up was 42 months, median survival was 39 months, and OS at three years was 52%. There was no significant difference in median survival between T1a nodules and T1b nodules (36 vs. 39 months, P=0.29) or for RFA and MWA (36 vs. 50 months, P=0.80). Ten patients had LP (47.6%), at a median time of 35 months. There was no significant difference in LP between T1a and T1b tumors (22 vs. 35 months, P=0.94) or RFA and MWA (35 vs. 17 months, P=0.18). Median OS with LP was 32 months compared to 39 months without LP (P=0.68). Three patients underwent repeat ablations. Mean time to LP following repeat ablation was 14.75 months. One patient had two repeat ablations and was disease free at 40-month follow-up. Conclusions Thermal ablation effectively treated or controlled stage IA NSCLC in medically inoperable patients. Three-year OS exceeded 50%, and LP did not affect OS. Therefore, thermal ablation is a viable option for medically inoperable patients with early stage NSCLC.

Abstract
Gastroesophageal reflux disease (GERD) is a common condition that places a significant burden on the healthcare system. Additionally, there have been concerns raised about potential risks of long-term proton pump inhibitors. Laparoscopic anti-reflux surgery is currently the gold standard option for patients when surgery is planned. However, there continues to be interest in an endoscopic, alternative to laparoscopic surgery. Transoral incisionless fundoplication (TIF) is being increasingly utilized for such patients. We review the indications, patient selection and technique for this procedure. A video of the procedure, which we previously published on CTSNet is also attached.

Abstract
Lung cancer continues to be the most common cause of cancer death. Screening programs for high risk patients with the use of low-dose computed tomography (CT) has led to the identification of small lung lesions that were difficult to identify using previous imaging modalities. Electromagnetic navigational bronchoscopy (ENB) is a novel technique that has shown to be of great utility during the evaluation of small, peripheral lesions, that would otherwise be challenging to evaluate with conventional bronchoscopy. The diagnostic yield of navigational bronchoscopy however is highly variable, with reports ranging from 59% to 94%. This variability suggests that well-defined selection criteria and standardized protocols for the use of ENB are lacking. Despite this variability, we believe that this technique is a useful tool evaluating small peripheral lung lesions when patients are properly selected.

Abstract
The incidence of Barrett's esophagus (BE) in the Western world has increased over the last decades. BE is considered a premalignant lesion that can progress to esophageal adenocarcinoma (EAC), a highly aggressive malignancy with poor survival rates. The close association between BE and EAC highlights the need for an early diagnosis in order to improve survival and outcomes in this group of patients. Although the evidence for BE screening with conventional endoscopy is controversial and limited by cost-effectiveness studies, screening can be suggested in patients with chronic gastroesophageal reflux disease (GERD) and two or more risk factors for EAC. Less invasive techniques with lower costs and higher acceptability by the patients may be useful for screening in the general population. Several novel techniques have been described to aid in the early diagnosis and management of BE and dysplasia. However, these techniques have shown variable results with higher costs, the need of specific training, and variable inter-observer imaging interpretation, making its widespread implementation problematic. High-definition/high-resolution white-light endoscopy (WLE) continues to be a well-accepted technique for the evaluation and surveillance of patients with BE. Further studies are required in order to establish the efficacy of less invasive methods that can be performed in an outpatient setting for BE screening in higher risk individuals.

Abstract
BACKGROUND Identification of small peripheral lung nodules during minimally invasive resection can be challenging. Electromagnetic navigational bronchoscopy (ENB) with injection of dye to identify nodules can be performed by the surgeon immediately prior to resection. We evaluated the effectiveness of ENB with dye marking to aid minimally invasive resection. METHODS Patients with peripheral pulmonary nodules underwent ENB before planned thoracoscopic or robotic-assisted thoracoscopic resection. Methylene blue was injected directly into the lesion for pleural-based lesions or peripherally for lesions deep to the pleural surface. Surgical resection was then immediately performed. Technical success was defined as identification of the dye marking within/close to the lesion with pathological confirmation after minimally invasive surgical resection. RESULTS Seventeen patients (19 nodules) underwent ENB with dye marking followed by minimally invasive resection. Median lesion size was 9 mm (4-32 mm) and the median distance from the pleura was 9.5 mm (1-40 mm). Overall success rate was 79% (15/19). In two cases the dye was not visualized and in the remaining two there was extravasation of dye into the pleural space. There were trends favoring technical success for nodules that were larger or closer to the pleural surface. Five patients required adhesiolysis to visualize the target lesion and all were successful. There were no significant adverse events and a definitive diagnosis was ultimately accomplished in all patients. CONCLUSIONS ENB with dye marking is useful for guiding minimally invasive resection of small peripheral lung nodules. ENB can be undertaken immediately before performing resection in the operating room. This improves workflow and avoids the need for a separate localization procedure.

Impact of Sublobar Resection on Pulmonary Function: Long-Term Results from American College of Surgeons Oncology Group Z4032 (Alliance). Ann Thorac Surg 2016; 102:230-8. [PMID: 27101728 DOI: 10.1016/j.athoracsur.2016.01.069] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2015] [Revised: 01/04/2016] [Accepted: 01/06/2016] [Indexed: 12/25/2022]
Abstract
BACKGROUND Sublobar resection (SR) in high-risk operable patients may result in a long-term decrease in pulmonary function. We previously reported 3-month pulmonary function outcomes from a randomized phase III study of SR alone compared with SR with brachytherapy in patients with non-small cell lung cancer. We now report long-term pulmonary function after SR. METHODS Pulmonary function was measured at baseline and at 3, 12, and 24 months. A decline of 10% or more from baseline in the percentage predicted forced expiratory volume of 1 percentage or in the diffusion capacity of the lung for carbon monoxide was considered clinically meaningful. The effect of study arm, tumor location, size, approach (video-assisted thoracoscopic surgery vs thoracotomy), and SR type (wedge vs segmentectomy) on pulmonary function was assessed using a Wilcoxon rank sum test. A generalized estimating equation model was used to assess the effect of each factor on longitudinal data, including all four time points. RESULTS Complete pulmonary function data at all time points was available in 69 patients. No significant differences were observed in pulmonary function between SR and SR with brachytherapy, thus the study arms were combined for all analyses. A decline of 10% or more (p = 0.02) in the percentage predicted forced expiratory volume in 1 second was demonstrated for lower-lobe resections at 3 months but was not at 12 or 24 months. A decline of 10% or more (p = 0.05) in the percentage predicted diffusion capacity of the lung for carbon monoxide was seen for thoracotomy at 3 months but was not at 12 or 24 months. CONCLUSIONS Clinically meaningful declines in pulmonary function occurred after lower lobe resection and after thoracotomy at 3 months but subsequently recovered. This study suggests that SR does not result in sustained decreased pulmonary function in high-risk operable patients.

Do Current Lung Cancer Screening Guidelines Apply for Populations With High Prevalence of Granulomatous Disease? Results From the First Brazilian Lung Cancer Screening Trial (BRELT1). Ann Thorac Surg 2015; 101:481-6; discussion 487-8. [PMID: 26409711 DOI: 10.1016/j.athoracsur.2015.07.013] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2015] [Revised: 05/25/2015] [Accepted: 07/09/2015] [Indexed: 12/29/2022]
Abstract
BACKGROUND Low-dose computed tomography (LDCT) screening for lung cancer has been demonstrated to be effective in reducing cancer mortality. However, these studies have not been undertaken in countries where the incidence of granulomatous disease is high. The First Brazilian Lung Cancer Screening Trial (BRELT1) has completed initial accrual and is now in the follow-up phase. We present results from the initial prevalence round of screening. METHODS The inclusion criteria were the same as those for the National Lung Cancer Screening Trial (NLST). Pulmonary nodules larger than 4 mm were considered positive and required evaluation by a multidisciplinary team. Indeterminate nodules were evaluated with fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) or biopsy when indicated. Statistical analysis was performed with Fisher's exact test to compare our positive findings with those of the NLST. RESULTS From January 2013 to July 2014, 790 participants were enrolled. Positive LDCT scans were reported in 312 (39.4%) participants, with a total of 552 nodules larger than 4 mm. The comparison between positive findings in the NLST (7,191 of 26,722 cases) and those in the BRELT1 (312 of 790 cases) showed a significant difference (p < 0.001). The positive predictive value was lower in BRELT1 than in the NLST (3.2% versus 3.8%, respectively). Follow-up imaging was indicated in 278 of 312 (89.1%) participants; 35 procedures were performed in 25 participants. In 15 cases, benign lesions were diagnosed. Non-small-cell lung cancer (NSCLC) was diagnosed in 10 patients (prevalence of 1.3%). In 8 patients (stage IA/IB disease), treatment was by resection only, in 1 patient neoadjuvant chemotherapy was used (stage IIIA), and in 1 patient advanced disease was diagnosed (stage IV). CONCLUSIONS Using NSLT criteria, a larger number of patients had positive scans (nodules), compared with previous lung cancer screening studies. However, the number of participants requiring surgical biopsy procedures and who were ultimately identified as having cancer was similar to other reports. This supports the role of screening in patient populations with a high incidence of granulomatous inflammation.

Radiofrequency ablation of stage IA non-small cell lung cancer in medically inoperable patients: Results from the American College of Surgeons Oncology Group Z4033 (Alliance) trial. Cancer 2015; 121:3491-8. [PMID: 26096694 DOI: 10.1002/cncr.29507] [Citation(s) in RCA: 148] [Impact Index Per Article: 16.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2015] [Revised: 04/08/2015] [Accepted: 04/14/2015] [Indexed: 01/17/2023]
Abstract
BACKGROUND This study evaluated the 2-year overall survival rate, adverse event rate, local control rate, and impact on pulmonary function tests for medically inoperable patients with stage IA non-small cell lung cancer (NSCLC) undergoing computed tomography (CT)-guided radiofrequency ablation (RFA) in a prospective, multicenter trial. METHODS Fifty-four patients (25 men and 29 women) with a median age of 76 years (range, 60-89 years) were enrolled from 16 US centers; 51 patients were eligible for evaluation (they had biopsy-proven stage IA NSCLC and were deemed medically inoperable by a board-certified thoracic surgeon). Pulmonary function tests were performed within the 60 days before RFA and 3 and 24 months after RFA. Adverse events were recorded and categorized. Patients were followed with CT and fludeoxyglucose positron emission tomography. Local control rate and recurrence patterns were analyzed. RESULTS The overall survival rate was 86.3% at 1 year and 69.8% at 2 years. The local tumor recurrence-free rate was 68.9% at 1 year and 59.8% at 2 years and was worse for tumors > 2 cm. In the 19 patients with local recurrence, 11 were re-treated with RFA, 9 underwent radiation, and 3 underwent chemotherapy. There were 21 grade 3 adverse events, 2 grade 4 adverse events, and 1 grade 5 adverse event in 12 patients within the first 90 days after RFA. None of the grade 4 or 5 adverse events were attributable to RFA. There was no significant change in the forced expiratory volume in the first second of expiration or the diffusing capacity of lung for carbon monoxide after RFA. A tumor size less than 2.0 cm and a performance status of 0 or 1 were associated with statistically significant improved survival of 83% and 78%, respectively, at 2 years. CONCLUSIONS RFA is a single, minimally invasive procedure that is well tolerated in medically inoperable patients, does not adversely affect pulmonary function tests, and provides a 2-year overall survival rate that is comparable to the rate reported after stereotactic body radiotherapy in similar patients.

Analysis of longitudinal quality-of-life data in high-risk operable patients with lung cancer: results from the ACOSOG Z4032 (Alliance) multicenter randomized trial. J Thorac Cardiovasc Surg 2014; 149:718-25; discussion 725-6. [PMID: 25500100 DOI: 10.1016/j.jtcvs.2014.11.003] [Citation(s) in RCA: 42] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2014] [Revised: 09/10/2014] [Accepted: 11/04/2014] [Indexed: 01/01/2023]
Abstract
BACKGROUND Prior studies have suggested that low baseline quality-of-life (QOL) scores predict worse survival in patients undergoing lung cancer surgery. However, these studies involved average-risk patients undergoing lobectomy. We report QOL results from a multicenter trial, American College of Surgeons Oncology Group Z4032, which randomized high-risk operable patients to sublobar resection (SR), or SR with brachytherapy, and included longitudinal QOL assessments. METHODS Global QOL, using the 36-item Short-Form Health Survey (SF36), and the dyspnea score from the University of California, San Diego Shortness of Breath Questionnaire (SOBQ) scale, was measured at baseline, 3, 12, and 24 months. SF36 physical component summary (PCS) and mental component summary (MCS) scores were standardized and adjusted for age and gender normals, with scores <50 indicating below-average health status. SOBQ scores were transformed to a 0-100 (poor-excellent) scale. Aims were to: (1) determine the impact of baseline scores on recurrence-free survival, overall survival, and 30-day adverse events (AEs); and (2) identify subgroups (surgical approach, resection type. tumor location, tumor size, respiratory function) with a ≥ 10-point decline or improvement in QOL after SR. RESULTS Two hundred twelve eligible patients were included. There were no significant differences in baseline QOL scores between arms. Median baseline PCS, MCS, and SOBQ scores were 42.7, 51.1, and 70.8, respectively. There were no differences in grade-3+ AEs, overall survival, or recurrence-free survival in patients with baseline scores ≤ median versus > median values, except for a significantly worse overall survival for patients with baseline SOBQ scores ≤ median value. There were no significant differences between the study arms in percentage change of QOL scores from baseline to 3, 12, or 24 months. Further comparison combining the 2 arms demonstrated a higher percentage of patients with a ≥ 10-point decline in SOBQ scores with segmentectomy compared with wedge resection (40.5% vs 21.9%, P = .03) at 12 months, with thoracotomy versus video-assisted thoracic surgery (VATS) (38.8% vs 20.4%, P = .03) at 12 months, and T1b versus T1a tumors (46.9% vs 23.5%, P = .020) at 24 months. A ≥ 10-point improvement in PCS score was seen at 3 months with VATS versus thoracotomy (16.5% vs 3.6%, P = .02). CONCLUSIONS In high-risk operable patients, poor baseline QOL scores were not predictive for worse overall or recurrence-free survival, or for higher risk for AEs following SR. VATS was associated with improvement in physical function at 3 months, and improved dyspnea scores at 12 months, lending support for the preferential use of VATS when SR is undertaken.

Abstract
Mediastinal parathyroid adenomas can be resected by sternotomy or video-assisted thoracoscopic surgery. Robot-assisted thoracic surgical approaches have recently been described. We report robotassisted thoracic surgical resection of a mediastinal parathyroid in a morbidly obese patient. Additional comorbidities included multiple pathological fractures related to hypercalcemia. Intraoperative parathyroid hormone levels confirmed successful removal of the adenoma. Hungry bone syndrome developed after surgery but eventually resolved. Robotassisted thoracic surgery avoided the need for sternotomy and associated concerns related to poor bone healing. Robot-assisted thoracic surgery has potential advantages over video-assisted thoracoscopic surgery in patients with obesity because of easier instrument articulation within the thoracic cavity rather than at the chest wall.
