Abstract
BACKGROUND Prolonged survival of patients with metastatic disease has furthered interest in metastasis-directed therapy (MDT). RESEARCH QUESTION There is a paucity of data comparing lung MDT modalities. Do outcomes among sublobar resection (SLR), stereotactic body radiation therapy (SBRT), and percutaneous ablation (PA) for lung metastases vary in terms of local control and survival? STUDY DESIGN AND METHODS Medical records of patients undergoing lung MDT at a single cancer center between January 2015 and December 2020 were reviewed. Overall survival, local progression, and toxicity outcomes were collected. Patient and lesion characteristics were used to generate multivariable models with propensity weighted analysis. RESULTS Lung MDT courses (644 total: 243 SLR, 274 SBRT, 127 PA) delivered to 511 patients were included with a median follow-up of 22 months. There were 47 local progression events in 45 patients, and 159 patients died. Two-year overall survival and local progression were 80.3% and 63.3%, 83.8% and 9.6%, and 4.1% and 11.7% for SLR, SBRT, and PA, respectively. Lesion size per 1 cm was associated with worse overall survival (hazard ratio, 1.24; P = .003) and LP (hazard ratio, 1.50; P < .001). There was no difference in overall survival by modality. Relative to SLR, there was no difference in risk of local progression with PA; however, SBRT was associated with a decreased risk (hazard ratio, 0.26; P = .023). Rates of severe toxicity were low (2.1%-2.6%) and not different among groups. INTERPRETATION This study performs a propensity weighted analysis of SLR, SBRT, and PA and shows no impact of lung MDT modality on overall survival. Given excellent local control across MDT options, a multidisciplinary approach is beneficial for patient triage and longitudinal management.

Abstract
BACKGROUND We sought to quantify the impact of pre- and postoperative variables on health-related quality of life (HRQOL) after left ventricular assist device (LVAD) implantation. METHODS Primary durable LVAD implants between 2012 and 2019 in the Interagency Registry for Mechanically Assisted Circulatory Support were identified. Multivariable modeling using general linear models assessed the impact of baseline characteristics and postimplant adverse events (AEs) on HRQOL as assessed by the EQ-5D visual analog scale (VAS) and the Kansas City Cardiomyopathy Questionnaire-12 (KCCQ) at 6 months and 3 years. RESULTS Of 22,230 patients, 9,888 had VAS and 10,552 had KCCQ reported at 6 months, and 2,170 patients had VAS and 2,355 had KCCQ reported at 3 years postimplant. VAS improved from a mean of 38.2 ± 28.3 to 70.7 ± 22.9 at 6 months and from 40.1 ± 27.8 to 70.3 ± 23.1 at 3 years. KCCQ improved from 28.2 ± 23.9 to 64.3 ± 23.2 at 6 months and from 29.8 ± 23.7 to 63.0 ± 23.7 at 3 years. Preimplant variables, including baseline VAS, had small effect sizes on HRQOL while postimplant AEs had large negative effect sizes. Recent stroke, respiratory failure, and renal dysfunction had the largest negative effect on HRQOL at 6 months, while recent renal dysfunction, respiratory failure, and infection had the largest negative effect at 3 years. CONCLUSIONS AEs following LVAD implantation have large negative effects on HRQOL in early and late follow-up. Understanding the impact of AEs on HRQOL may assist shared decision-making regarding LVAD eligibility. Continued efforts to reduce post-LVAD AEs are warranted to improve HRQOL in addition to survival.

Abstract
The latissimus dorsi muscle is the workhorse flap for intrathoracic reconstruction. Prior thoracotomy, which divides the latissimus dorsi muscle, limits the muscle's intrathoracic reach. We present our experience using the distal portion of the muscle for intrathoracic reconstruction based off an intercostal vessel. We also demonstrate the ability of this intercostal perforator to allow for chimeric flap elevation with a separate skin paddle, depending on the branching pattern of the intercostal vessels. This study provides a case series of three consecutive patients, treated between September 2021 and June 2022. The intrathoracic pathology addressed in these patients are bronchopleural fistula, aortoesophageal fistula, and bronchoesophageal fistula. All patients had the resolution of symptoms related to intrathoracic fistulae and did not experience recurrence. This novel pedicled muscle flap can be an additional option for patients with prior thoracotomy and avoids the morbidity which can be seen with the serratus or rectus abdominis muscle flaps.

Abstract
Every effort must be made by the leaders in our field, as well as every individual cardiothoracic surgeon, to assure equal opportunity for ALL cardiothoracic surgeons, regardless of race, gender, or any other sociodemographic source of bias. Every effort must be made by every surgeon, not just those in particular leadership roles. Opportunity for advancement MUST be equal in multiple domains, including clinical practice, patient referral, clinical leadership, academic leadership, institutional leadership, and leadership in professional medical and surgical societies. Such actions to minimize bias and promote inclusivity will also ensure that cardiothoracic surgical care is provided by a workforce that represents the diversity of patients whom we serve. In the final analysis, it is an absolute fact that gender differences in payments to cardiothoracic surgeons are absolutely unacceptable and cannot be tolerated.

Abstract
PURPOSE This phase Ib/2 trial investigated pembrolizumab-containing trimodality therapy in patients with gastroesophageal junction (GEJ) adenocarcinoma. PATIENTS AND METHODS Patients with GEJ adenocarcinoma (cT1-3NanyM0) received neoadjuvant pembrolizumab-containing chemoradiation (CROSS regimen) followed by surgical resection and adjuvant pembrolizumab. The primary endpoints were tolerability in the first 16 patients and pathologic complete response [pCR (ypT0N0)]. Secondary endpoints included progression-free survival (PFS) and overall survival (OS). An independent propensity-score-matched cohort (treated with CROSS without immunotherapy) was used for comparison. Exploratory analyses included immune biomarkers in the tumor microenvironment (TME) and plasma. RESULTS We enrolled 31 eligible patients, of whom 29 received all expected doses of neoadjuvant pembrolizumab and 28 underwent R0 resection. Safety endpoints were met. The primary efficacy endpoint was not met [7/31 (22.6%) achieved pCR]. Patients with high [i.e., combined positive score (CPS) ≥ 10] baseline expression of programmed death (PD)-L1 in the TME had a significantly higher pCR rate than those with low expression [50.0% (4/8) vs. 13.6% (3/22); P = 0.046]. Patients with high PD-L1 expression also experienced longer PFS and OS than propensity-score-matched patients. Among trial patients with PD-L1 CPS < 10, unprespecified analysis explored whether extracellular vesicles (EV) could identify further responders: an elevated plasma level of PD-L1-expressing EVs was significantly associated with higher pCR. CONCLUSIONS Adding pembrolizumab to trimodality therapy showed acceptable tolerability but did not meet the pre-specified pCR endpoint. Exploratory analyses suggested that high PD-L1 expression in the TME and/or on EVs may identify patients most likely to achieve tumor response.

Abstract
BACKGROUND/AIM Adaptive radiation therapy (ART) is a technique capable of reducing radiation dose to normal tissue without compromising local control. For potentially resectable thymoma, induction therapy is standard of care. Because large disease volume is common in this context, ART has been suggested to reduce toxicity from induction chemoradiation. This has not been previously illustrated in the literature. CASE REPORT A 38-year-old man with initially unresectable thymoma was treated with induction chemoradiation including cisplatin and etoposide. He received 45 Gy in 25 fractions and ART was utilized to shrink the radiotherapy field for the final 10 fractions. RESULTS Thymectomy showed Masaoka stage III disease with negative margins. He experienced no treatment-related toxicity and has no evidence of disease 8 years after diagnosis. CONCLUSION Induction chemoradiotherapy with ART appears to be feasible, safe, and efficacious for locally advanced intact thymoma.

Abstract
PURPOSE OF REVIEW Cancer patients who require surgery often experience peri-operative symptoms, including nausea, anxiety, and pain, which can significantly impair quality of life. Here, we review the evidence for using integrative approaches to manage these peri-operative symptoms. RECENT FINDINGS Conventional peri-operative pharmacologic interventions, such as opiates for pain control, can lead to adverse effects such as respiratory depression, prolonged hospital course, and long-term dependence. Integrative medicine, also known as complementary and alternative medicine (CAM), has been explored as way to reduce peri-operative symptoms. Acupuncture, guided imagery, and loving-kindness meditation have all shown potential efficacy in reducing both peri-operative pain and anxiety in retrospective studies and small randomized controlled trials. Integrative medicine techniques, such as acupuncture, are a promising approach to control peri-operative symptoms without the associated adverse effects of more conventional pharmacologic interventions.

Abstract
BACKGROUND Women in Thoracic Surgery (WTS) has previously reported on the status of women in cardiothoracic (CT) surgery. We sought to provide a 10-year update on women in CT. METHODS An anonymous REDCap survey link was emailed to female diplomats of the ABTS. Survey questions queried respondents regarding demographics, training, accolades, practice details, and career satisfaction. The survey link was open for 30 days. Results were compared to the 2019 Society of Thoracic Surgeons work force survey. Descriptive analyses were performed using frequency and proportions. Comparisons were performed using Student's t-tests, Fisher exact and chi-squared tests. RESULTS Of 354 female diplomats, 309 were contacted and 176 (57%) responded. The majority of respondents were age 36-50 (59%), Caucasian (67.4%), and graduated from traditional-track programs (91.4%). Most respondents reported practicing in an urban (64%) and academic setting (73.1%). 36.4% and 23.9% reported a general thoracic and adult cardiac practice (22.7% mixed practice, 9.6% congenital). Fifty percent of respondents reported salaries between $400,000-700,000 annually; 37.7% reported salaries <90% of their male colleagues. 21.6% of respondents in academia are full professor; 53.4% report having a leadership role. While 74.1% would pursue a career in CT again, only 27.3% agreed that CT surgery is a healthy and positive environment for women. CONCLUSIONS The number of women in CT surgery has steadily increased. While women are rising in academic rank and into leadership positions, salary disparities and the CT surgery work environment remain important issues in achieving a diverse work force.

Abstract
OBJECTIVES Esophagectomy is associated with significant morbidity and mortality. The authors assessed the relationship between intraoperative fluid (IOF) administration and postoperative pulmonary outcomes in patients undergoing a transthoracic, transhiatal, or tri-incisional esophagectomy. DESIGN Retrospective cohort study (level 3 evidence). SETTING Tertiary care referral center. PARTICIPANTS Patients who underwent esophagectomy from 2007 to 2017. INTERVENTIONS The IOF rate (mL/kg/h) was the predictor variable analyzed both as a continuous and binary categorical variable based on median IOF rate for this cohort (11.90 mL/kg/h). MEASUREMENTS Primary outcomes included rates of acute respiratory distress syndrome (ARDS) within ten days after esophagectomy. Secondary outcomes included rates of reintubation, pneumonia, cardiac or renal morbidity, intensive care unit admission, length of stay, procedure-related complications, and mortality. Multivariate regression analysis determined associations between IOF rate and postoperative outcomes. Analysis was adjusted for age, sex, body mass index, procedure type, year, and thoracic epidural use. MAIN RESULTS A total of 1,040 patients comprised this cohort. Tri-incisional esophagectomy was associated with a higher hospital mortality rate (7.8%) compared with transthoracic esophagectomy (2.6%, p = 0.03) or transhiatal esophagectomy (0.7%, p = 0.01). Regression analysis revealed a higher IOF rate was associated with greater ARDS within ten days (adjusted odds ratio [OR] = 1.03, p = 0.01). For secondary outcomes, a higher IOF rate was associated with greater hospital mortality (adjusted OR = 1.05, p = 0.002), although no significant association with 30-day hospital mortality was identified. CONCLUSIONS Increased IOF administration during esophagectomy may be associated with worse postoperative pulmonary complications, specifically ARDS. Future well-powered studies are warranted, including randomized, controlled trials comparing liberal versus restrictive fluid administration in this surgical population.

Abstract
Lung ablation has been introduced into lung cancer treatment for about two decades. Currently, 3 main choices of thermal energy for lung ablation are radiofrequency ablation (RFA), microwave ablation (MWA), and cryoablation. As a mostly palliative, occasionally curative intent local treatment, the feasibility and safety of lung ablation have been validated in small size lung cancer treatment, especially in lung tumor ≤3 cm. Improved techniques and experience in recent years help render outcomes much better than before for lung cancer patients who are medically inoperable with early stage primary lung cancer, and patients with oligometastasis or local recurrence. For stage IA non-small cell lung cancer (NSCLC) patients underwent RFA, 1- and 2-year overall survival rate were reported as 86.3% and 69.8%. And 1- and 2-year local recurrence rate were reported as 68.9% and 59.8%. Limitations, including heat sink, skin burn, and inconsistent heat conduction, are observed in the first applied ablation technique, RFA. MWA and cryoablation are developed to overcome these limitations and achieve the goal of less morbidity. Generally, imaged guided thermal ablation has a good safety profile, with pneumothorax as the most common morbidity. This article will mainly discuss the current features and application of these ablation techniques in lung cancer treatment.

Abstract
BACKGROUND Minimally invasive esophagectomy (MIE) is increasingly performed in various ways. The lack of international definitions and nomenclature makes accurate comparison of outcomes difficult. METHODS An international, multispecialty consensus-writing committee constructed definitions and nomenclature for MIE. After a PubMed search, vetting, and review with all authors, a consensus was reached. RESULTS The proposed definition for MIE is an operation "that removes part or all of the esophagus, does not retract, lift, spread or remove any part of the chest or abdominal wall and the surgeon's and assistant's vision of the operative field is via a monitor, the patient's tissue is manipulated only by instruments that are controlled by the operating surgeon or team, except for during the neck portion if used." A flexible nomenclature is proposed that attempts to describe current and future operations and systems. CONCLUSIONS Definitions and nomenclature for MIE are needed to ensure that future studies accurately compare results and outcomes of similar operations. Nomenclatures allow surgeons, researchers, and patients from different cultures to use a common language to facilitate communication and compare. This process is required in order to improve patient outcomes globally to drive adoption of best of practice, yet is lacking for MIE.

Abstract
INTRODUCTION To evaluate the outcomes of video-assisted thoracoscopic surgery (VATS) during transvenous lead extractions (TLEs). METHODS AND RESULTS Ninety-one high-risk patients who underwent TLE in the operating room from January 1, 2015, to March 31, 2017, were included in the study. Of these, 9 patients underwent VATS during TLE. Their clinical characteristics, indications for lead extraction, and complications associated with TLE in the 9 patients who had VATS were compared with those for the 82 patients who did not have VATS. The mean (SD) age of the study patients was 61 (17) years (64.8% were male). The lead dwell time, number of leads extracted, and clinical comorbidities were similar between the 2 groups. Superior vena cava (SVC) tear occurred in 2 of the 9 patients in VATS group and in 1 of the 82 in the non-VATS group (22.2% vs. 1.2%, P = 0.03). Of the 2 patients in the VATS group who had SVC tears, in 1 the tear was visualized immediately and there was no hemodynamic compromise. In the other patient, the SVC tear was within the pericardium; the blood pressure recovered quickly after sternotomy and repair. Both patients had complete lead extraction and survived hospitalization. The patient in the non-VATS group who had an SVC tear had a successful repair but died of postoperative complications. CONCLUSIONS Utilization of VATS to facilitate TLE is beneficial for early recognition of SVC tear and timely surgical repair in select high-risk patients.

Abstract
The diaphragm is an unique skeletal muscle separating the thoracic and abdominal cavities with a primary function of enabling respiration. When abnormal, whether by congenital or acquired means, the consequences for patients can be severe. Abnormalities that affect the diaphragm are often first detected on chest radiographs as an alteration in position or shape. Cross-sectional imaging studies, primarily CT and occasionally MRI, can depict structural defects, intrinsic and adjacent pathology in greater detail. Fluoroscopy is the primary radiologic means of evaluating diaphragmatic motion, though MRI and ultrasound also are capable of this function. This review provides an update on diaphragm embryogenesis and discusses current imaging of various abnormalities, including the emerging role of three-dimensional printing in planning surgical repair of diaphragmatic derangements.

Abstract
BACKGROUND Treatments for superior sulcus tumor (SST) have evolved, with induction chemoradiotherapy providing an improved R0 resection rate. We reviewed the treatment and outcomes of SSTs in a single institution to identify prognostic factors and optimal treatment strategy. METHODS Details of patients who underwent any type of treatment for SST from 1997 through 2014 were retrospectively collected. Survival was calculated by the Kaplan-Meier method. Proportional hazards regression was used to test the prognostic significance of factors in univariate and multivariate models. RESULTS Eighty-nine patients were identified, 8 of whom had M1 disease and were excluded from the analysis. Of the 48 surgical patients, 44 received preoperative induction treatments, with 12 (25%) achieving a pathologic complete response (pCR), 23 with minimal residual disease, and 9 with gross residual disease. Complete resection was achieved in 40 surgical cases. As expected, nonsurgical patients had worse survival than did surgical patients (median survival, 2.1 versus 5.8 years; nonsurgical versus surgical hazard ratio [HR], 2.1; 95% confidence interval [CI], 1.2-3.7; p = 0.01). By multivariable Cox analysis, smoking status (HR, 4.4; 95% CI, 1.5-13.0; p = 0.01) and previous or concurrent malignancy (HR, 4.73; 95% CI, 1.6-13.9; p = 0.0.005) were prognostic factors for surgical patients. There were no statistically significant prognostic factors for nonsurgical patients. CONCLUSIONS Chemoradiotherapy followed by surgical treatment is our favored treatment for operable candidates. Preoperative induction treatments were associated with a 25% pCR rate for surgical patients. Candidates for surgical therapy are expected to have longer survival than those who are not candidates for resection.

Abstract
INTRODUCTION Multifocal lung cancer is an increasingly common clinical scenario, but there is lack of high-level evidence for its optimal treatment. Thus, we surveyed members of the interdisciplinary International Association for the Study of Lung Cancer on their therapeutic approaches and analyzed the resultant practice patterns. METHODS We described the clinical scenario of an otherwise healthy 60-year-old man with bilateral pulmonary nodules and asked the 6373 members of the International Association for the Study of Lung Cancer whether they would recommend surgery, and if so, the extent of surgery. We also asked what other measures would be recommended to complete the staging and whether radiation therapy or chemotherapy would be suggested. RESULTS We received 221 responses (response rate 3.5%) from multiple specialists. Most respondents (140 [63%]) recommended surgery for this scenario. Surgeons were significantly more likely to recommend surgery than were those in other specialties. Of those who recommended surgery, most would obtain a PET/CT scan to rule out distant metastases and a magnetic resonance imaging scan to rule out brain metastases; but in the absence of radiographic lymph node involvement, most would not stage the mediastinum by bronchoscopy or mediastinoscopy before resection. When surgery was not recommended or declined, respondents commonly recommended radiation. CONCLUSIONS This survey suggests that therapeutic recommendations for multifocal lung cancer are influenced to a large extent by physicians' specialty training, probably because of the lack of high-level evidence for its standard treatment. Ongoing systematic and multidisciplinary approaches with robust short-term and long-term patient outcomes may improve the quality of evidence for the optimal management of this clinical entity.

Abstract
Four healthy adult dogs (Golden Retrievers aged 6 years and 9 years, Dalmatian aged 13 years, and Mastiff aged 5 years) developed clinical signs of acute respiratory disease and died within 2 to 7 days of onset of clinical signs. The lungs of the 3 dogs submitted for necropsy were diffusely and severely reddened due to hyperemia and hemorrhage. Microscopic lesions in all dogs were suggestive of acute viral or toxic respiratory damage and varied from acute severe fibrinonecrotic or hemorrhagic bronchopneumonia to fibrinous or necrotizing bronchointerstitial pneumonia. Necropsied dogs also had hemorrhagic rhinitis and tracheitis with necrosis. Virus isolation, transmission electron microscopy, and polymerase chain reaction were used to confirm the presence of canid herpesvirus 1 (CaHV-1) in the lung samples of these dogs. Lung tissues were negative for influenza A virus, canine distemper virus, canine parainfluenza virus, canine respiratory coronavirus, and canine adenovirus 2. Canid herpesvirus 1 has been isolated from cases of acute infectious respiratory disease in dogs but has only rarely been associated with fatal primary viral pneumonia in adult dogs. The cases in the current report document lesions observed in association with CaHV-1 in 4 cases of fatal canine herpesvirus pneumonia in adult dogs.

Abstract
Sclerosing mediastinitis is a rare, progressive condition characterized by extensive fibrotic reaction. We report the first known case of symptomatic, extrinsic compression of the carotid artery by fibrotic extension of sclerosing mediastinitis. A 54-year-old woman began experiencing neurologic symptoms from extension of a known mediastinal mass resulting in 70% to 79% stenosis of the right internal carotid artery. The stenosis was treated with endovascular stenting. Completion angiogram revealed a good result with <10% residual stenosis. At 18-month follow-up, the patient was symptom free without evidence of re-stenosis. Endovascular therapy provides a novel and durable solution in the midterm to this very rare problem.

Abstract
Aortic injuries presenting in a delayed fashion after attempted repair of an acute injury are uncommon. We report a case of a patient presenting with an initial aortic injury associated with thoracic spinal hardware placement, which was repaired with an open and endovascular approach, and 5 months later presented with hemoptysis. The cause of hemoptysis was erosion of the descending thoracic aorta between the spinal hardware and the thoracic endograft. The patient underwent descending aorta replacement with a Dacron tube graft, removal of the hardware, and coverage with a pedicled omental flap. This is a unique presentation of erosion of the aorta between the spinal hardware and the earlier placed endovascular stent-graft.

Abstract
Primary cardiac angiosarcoma is a rare but the most common malignant neoplasm of the heart in adults. The objective of this study is to analyze the clinicopathologic characteristics of primary cardiac angiosarcoma. Ten cases of primary cardiac angiosarcoma treated in a single institution were analyzed for their clinical, pathologic, and immunohistochemical features. There were 6 men and 4 women, with a mean age of 40 years (range, 20-61 years). The patients commonly presented with dyspnea and distant metastasis. All tumors were located in the right atrium, with a mean tumor size of 6.8 cm. Tumors were hemorrhagic, with variegated tan-brown solid areas. Histologically, they exhibited high-grade morphology with mixed solid growth and anatomizing channels. Frequent mitoses and tumor necrosis were common. The tumors were strongly positive for CD31, CD34, FLI-1, and WT-1 but negative for AE1/3, D2-40, human herpesvirus 8, and epidermal growth factor receptor. The tumor cells were focally reactive to p53, with a high rate of Ki-67 expression. A complete tumor resection was not possible in any of the patients because of the size or extensive local invasion of the tumor. Overall survival ranged from 1 to 81 months (mean, 26.6 months) after initial histologic diagnosis. Primary cardiac angiosarcomas are rare tumors that commonly arise in the right atrium. The mean age is much younger than that of soft tissue angiosarcoma. Regional tumor extension and distant metastasis are extremely common at the time of diagnosis. Surgical resection with adjuvant chemotherapy is currently the preferred treatment, and survival time appears to be inversely correlated with the tumor size and degree of regional tumor extension at the time of surgery.

Abstract
OBJECTIVE Primary cardiac sarcomas are rare tumors carrying poor prognosis. Resection remains the primary therapy. Especially in recent years, chemotherapy and radiation have been used adjunctively. METHODS All patients (n = 27) surgically treated for primary cardiac sarcoma at two tertiary referral centers from January 1990 to January 2006 were retrospectively reviewed. RESULTS There were 13 women and 14 men, with 26 resections and 1 palliative debulking performed. Cardiac explantation was necessary in 8 cases because of tumor location. Concomitant valve surgery (repair or replacement) or coronary artery bypass grafting was performed in 9 and 3 patients, respectively. Synchronous or staged resections of associated pulmonary metastases were performed in 6 and 2 patients, respectively. Operative mortality was 7.4% (2/27). Preoperative or postoperative chemotherapy was administered to 16 and 19 patients, respectively. At follow-up (median 22 months, range, 2-119 months), 12 patients were alive, with 7 tumor free. Among patients who underwent resection with curative intent and survived surgery (n = 24), median survival was 23.5 months (range 4-119 months). Patients who underwent surgical resection, radiofrequency ablation, or radiation treatment for tumor recurrence (local or metastatic, n = 7) had median survival of 47 months (range 16-119 months), whereas patients with no further intervention for recurrent disease (n = 7) had median survival of 25 months (range 8-34 months). CONCLUSIONS Multimodal therapy can achieve reasonable survival for patients with resected cardiac sarcomas. Patients with local tumor recurrence or metastatic disease may still benefit from aggressive treatment.

Abstract
INTRODUCTION Anatomic resection is currently the standard of care for patients with stage I non-small cell lung cancer (NSCLC). Some stage I patients are unable to tolerate lobectomy because of limited lung function or prohibitive comorbidities. In this study, we retrospectively compared the outcome of patients treated with wedge resection or three-dimensional (3-D) conformal radiation therapy, the most common treatment modalities used for such high-risk patients. METHODS All patients with stage I NSCLC from 1988 to 2005 who were not considered candidates for anatomic surgical resection were reviewed. Univariate and multivariate analyses were performed to assess the influence of 3-D conformal radiation and surgery on overall survival and recurrence-free survival. Propensity score-matched analysis and cost assessments were performed to compare outcomes with both modalities. Propensity matching was performed for gender, histology, tumor size, performance status, and age. RESULTS Of 160 patients studied, 68 patients received limited resection and 92 patients received 3-D conformal radiation. Univariate and multivariate analyses suggested a trend toward improved outcome in limited resection. Propensity matching was performed with 34 matched pairs and demonstrated no statistically significant difference in overall survival or recurrence-free survival. The mean cost of radiation therapy ($32,735) was not statistically significantly different from surgery ($30,411). CONCLUSION In high-risk patients with NSCLC, limited resection has a tendency towards improved outcome. A propensity matched analysis did not show a clear benefit for limited resection, which may be due in part to an inadequate number of patients for analysis and/or increased comorbidities of patients treated with 3-D conformal radiation.

Abstract
BACKGROUND The current American Joint Committee on Cancer (AJCC) esophageal cancer staging for nodal status is difficult to interpret and is based solely on lymph node location relative to the primary tumor's esophageal location. Recent reports suggest that the number of lymph nodes involved is also an important factor. We reviewed our esophageal experience to propose an improved nodal staging system. METHODS In all, 1,027 patients with resected esophageal cancer from 1970 to 2005 were reviewed. Lymph nodes stations were assigned according to AJCC criteria. Overall survival was assessed by Kaplan-Meier analysis. The impact of location, number of involved lymph nodes, and use of preoperative chemotherapy or radiation therapy, or both, was assessed. RESULTS Nonregional nodal involvement (n = 17) was associated with decreased survival compared with regional (n = 441) or celiac nodal (n = 73) involvement (3-year: 0% versus 24% and 23%; p < 0.001). The number of involved lymph nodes was strongly associated with survival (3-year: 0 nodes = 63%, 1 to 3 nodes = 31%, more than 3 nodes = 13%; p < 0.001), and multivariable Cox proportional-hazards analysis suggested that the location and number of involved lymph nodes were independent predictors of survival (p < 0.001). We propose a modified nodal staging system that designates celiac nodes as regional and includes number of involved nodes: pN0, no nodes (3 years = 63%, n = 496); pN1-regional, 1 to 3 nodes (3 years = 32%, n = 292); pN2-regional, more than 3 nodes (3 years = 14%, n = 222); pN3-nonregional node (3 years = 0%, n = 17 [p < 0.0001]). This modified nodal staging system better predicts survival than the current AJCC nodal staging system in which survival for pN1 (3 years = 24%) and pM1a (3 years = 23%) do not differ (p = 0.67). The use of induction before surgical resection did not alter the predictive effect of the new nodal staging system. CONCLUSIONS Modification of the AJCC nodal classification system to incorporate the number of involved lymph nodes with regional and nonregional node location simplifies and better predicts long-term survival than does the current AJCC nodal system.

Abstract
This study seeks to determine whether a 6-hour abdominal radiograph after oral Gastrografin is a reliable indicator for nonoperative treatment in patients with a clinically equivocal small bowel obstruction. We collected retrospective data from medical records. Patients who received a Gastrografin transit time (GGTT) study between January 1995 and September 1998 were included in the study. Patients who did not appear to be obvious operative candidates, but had signs of intestinal obstruction, underwent a GGTT study. Serial plain abdominal radiographs were taken. If the contrast was in the colon within 6 hours, then the result was negative. A total of 418 GGTT studies were reviewed. Contrast reached the colon within 6 hours in 283 (68%) patients, and 247 (88%) of these patients were managed nonoperatively. The positive predictive value, negative predictive value, sensitivity, and specificity of Gastrografin reaching the colon within 6 hours were 48, 87, 64, and 78, respectively. False negatives included high-grade partial obstructions that ultimately required surgery. Recent operation preceded the GGTT in 128 (31%) cases. Of these 128 patients, only 17 (14%) received an operation. Although the decision to operate or not should never be based on a GGTT study alone, GGTT studies are of significant help in the clinical management of patients suspected to have a small bowel obstruction. GGTT allows for the judicious selection of the appropriate patient for nonoperative management. GGTT studies are cost effective, safe, and clinically useful when attempting to treat patients conservatively.
