The Effect of Neoadjuvant Therapy on Esophagectomy for cT2N0M0 Esophageal Adenocarcinoma.

BACKGROUND: For cT2N0M0 esophageal adenocarcinomas, the effects of neoadjuvant chemoradiotherapy (NT) on surgical outcomes and the oncological benefits to the patients are debatable. In this study, we investigated the optimal management for cT2N0M0 adenocarcinoma (1) assessing the perioperative impact of NT on esophagectomy and (2) evaluating the oncologic effect of NT in a homogeneous group of patients with clinical stage IIA. We hypothesized that NT does not negatively affect perioperative outcomes and provides an oncologic benefit to selected patients with cT2N0M0 disease. METHODS: The National Cancer Database was queried (2010-2019) for patients with cT2N0M0 esophageal adenocarcinoma undergoing esophagectomy. After propensity-matching to adjust for differences in patient and tumor characteristics, we compared postoperative outcomes (logistic regression) and survival (Kaplan-Meier and Cox regression) among those who underwent NT vs upfront surgery (S). RESULTS: This study included 3413 patients, of whom 2359 (69%) received NT, and 1054 (31%) S. In contrast to those who underwent S, in the matched cohort, patients treated with NT had comparable conversion rates (8% vs11.1%, p = 0.06), length of stay (9 vs 10 days, p = 0.078), unplanned readmission (5.4% vs 8.8%, p = 0.109), and 30- (3.9% vs 3.7%, p = 0.90) and 90-day mortality (5.7% vs 4.7%, p = 0.599). In addition, NT associated with improved survival in patients with cT2N0M0 tumors > 5 cm (HR 0.30, 95% CI 0.17-0.36). CONCLUSIONS: NT does not appear to increase technical complexity or to adversely affect postoperative outcomes after esophagectomy. Furthermore, minimally invasive esophagectomy is feasible following NT, with comparable conversion rates to those who had upfront surgery. Lastly, NT was selectively associated with improved survival in patients with cT2N0M0 esophageal cancer.

Trends and Disparities in Robotic Surgery Utilization for Non-Small Cell Lung Cancer.

INTRODUCTION: Robotic surgery has become an increasingly utilized approach for resectable lung cancer. However, availability may be limited for certain patient populations, underscoring inequity in access to innovative surgical techniques. We hypothesize that there is an association between social determinants of health and robotic surgery utilization for resectable non-small cell lung cancer (NSCLC). METHODS: We queried the National Cancer Database (2010-2019) for patients with clinical stage I-III NSCLC who underwent resection, stratifying the cohort based on surgical technique. Multivariable logistic regression analysis was performed to identify associations between sociodemographic and clinicopathologic factors and the robotic approach. RESULTS: Among the 226,455 clinical stage I-III NSCLC patients identified, 34,059 (15%) received robotic resections, 78,039 (34.5%) underwent thoracoscopic resections, and 114,357 (50.5%) had open resections. Robotic surgery utilization increased from 3.1% in 2010 to 34% in 2019 (P < 0.001). Despite this, after adjusting by clinical stage, extent of resection, site of tumor, and receipt of neoadjuvant therapy, multivariable analysis revealed various sociodemographic and treatment facility factors that were associated with underutilization of this approach: lack of insurance (adjusted odds ratio [aOR] 0.83, 95% confidence interval [CI] 0.73-0.93), lower income brackets (aOR 0.93, 95% CI 0.91-0.96), provincial settings (urban aOR 0.79, 95% CI 0.76-0.82; rural aOR 0.57, 95% CI 0.51-0.64), and treatment at community centers (comprehensive community cancer programs aOR 0.73, 95% CI 0.70-0.75; community cancer programs aOR 0.51, 95% CI 0.47-0.55). CONCLUSIONS: This study suggests that disparities in determinants of health influence accessibility to robotic surgery for resectable NSCLC. Identification of these gaps is crucial to target vulnerable sectors of the population in promoting equality and uniformity in surgical treatment.

Incidental Duplicate Vas Deferens Discovered During Inguinal Hernia Repair With Incarcerated Bladder.

Duplication of the vas deferens is a rare congenital anomaly that has been encountered during inguinal hernia repair, orchidopexy, varicocelectomy, vasectomy, and radical prostatectomy. Identification of the duplicated vas deferens is crucial intraoperatively to avoid iatrogenic injury to the structure and the risks that come with failure to correctly distinguish the structure. We report a case of duplicated vas deferens and incarcerated urinary bladder during a laparoscopic converted to open left direct inguinal hernia repair.

Sublobar resection is associated with less lymph nodes examined and lower delivery of adjuvant therapy in patients with 1.5- to 2.0-cm clinical IA2 non-small-cell lung cancer: a retrospective cohort study.

OBJECTIVES: CALGB140503, in which nodal sampling was mandated, reported non-inferior disease-free survival for patients undergoing sublobar resection (SLR) compared to lobectomy (L). Outside of trial settings, the adequacy of lymphadenectomy during SLR has been questioned. We sought to evaluate whether SLR is associated with suboptimal lymphadenectomy, differences in pathologic upstaging and survival in patients with 1.5- to 2.0-cm tumours using real-world data. MATERIALS AND METHODS: Using the National Cancer Database(2018-2019), we evaluated patients with 1.5- to 2.0-cm non-small-cell lung cancer who underwent resection (sublobar versus lobectomy). We studied factors associated with nodal upstaging (logistic regression) and survival (Cox regression and Kaplan-Meier method) after propensity matching to adjust for differences among groups. RESULTS: Among 3196 patients included, SLR was performed in 839 (26.3%) (of which 588 were wedge resections) and L was performed in 2357 (73.7%) patients. More patients undergoing SLR (21.7%) compared to L (2.1%) had no lymph nodes sampled (P < 0.001). Those undergoing SLR had fewer total lymph nodes examined (4 vs 11, P < 0.001) and were less likely to have pathologic nodal metastases (4.7% vs 9%, P < 0.001) compared to L. Multivariable analysis identified L [adjusted odds ratio (aOR) 2.21, 95% confidence interval, 1.47-3.35] to be independently associated with pathologic N+ disease. Overall survival was not associated with the type of procedure but was significantly decreased in those with N+ disease. CONCLUSIONS: Despite comparable overall survival to L, SLR is associated with suboptimal lymphadenectomy in patients with 1.5-2.0 cm non-small-cell lung cancer. Surgeons should be careful to perform adequate lymphadenectomy when performing SLR to mitigate nodal under-staging and to identify appropriate patients for systemic therapy.

Elective complex ventral hernia repair in contaminated fields: A propensity score-matched analysis of long-term quality of life and outcomes between different prostheses.

BACKGROUND: Randomized studies have endorsed nonabsorbable prosthetics for contaminated ventral hernia surgery, yet the broader applicability and impact on patient-reported outcomes are still questioned. Here, we evaluated the long-term outcomes of elective contaminated ventral hernia repairs (based on Centers of Disease Control and Prevention [CDC] wound classification) using real-world data from a multicenter US cohort, focusing on quality of life and postoperative pain. METHODS: The Abdominal Core Health Quality Collaborative database was queried for patients undergoing elective contaminated (CDC class II-IV) ventral hernia repair (2013-2023). After propensity matching, we compared long-term differences in patient-reported quality of life and pain scores (by HerQLes and PROMIS questionnaires) among those who underwent repair with nonabsorbable, absorbable synthetic, and biologic mesh. RESULTS: A total of 1,073 patients were included, of whom 920 (86%), 56 (5%), and 97 (9%) underwent repair with nonabsorbable, absorbable synthetic, and biologic mesh, respectively. Among them, the median age was 62 years (interquartile range [IQR] 53-70), and 523 (49%) were male. The median length and width of the defect were 20 cm (IQR 12-25) and 13 cm (IQR 8-16), respectively. A transversus abdominis release was performed in 716 patients (67% of all cases). In most cases, the mesh was positioned in the retro-rectus (85%) and/or the preperitoneal space (45%). Before and after propensity matching (n = 185), the change from baseline in HerQLes and PROMIS scores at 6 months and at 1, 3, 5, and 6 years was comparable between different types of mesh. Lastly, there were no differences in readmission, surgical site infection, or surgical site occurrence at 30 days. Recurrence at 1 year was also comparable among groups. CONCLUSION: In the long term, there were no differences in quality of life or pain scores with nonabsorbable, absorbable synthetic, or biologic mesh for elective ventral hernia repair in contaminated fields.

The Representation of Women Moderators at The Society of Thoracic Surgeons Annual Meeting.

BACKGROUND: Recently, there has been an increase in the representation of women within the cardiothoracic surgery workforce, with discussions about gender equity garnering interest. We sought to identify whether this increase is accompanied by commensurate selection for representation at national meetings. METHODS: Online archives of The Society of Thoracic Surgeons (STS) Annual Meetings were reviewed from 2015 to 2024. Data regarding the moderator's gender were abstracted. The gender distribution of moderators across the various session categories was surveyed, and subgroup analyses were performed. RESULTS: During the years of study, the STS Annual Meeting Taskforce selected 983 moderators to participate in the conference, including 218 women. The representation of women moderators demonstrated a favorable, upward trend. In 2015, 12.1% of moderators were women, with a consistent rate from 2015 to 2018. There was a noticeable rise in invited women moderators in 2019, with 25.4% of moderators being women. This proportion increased to 36.9% women in 2024. General Thoracic sessions have consistently included a greater percentage of women moderators compared with other sessions. Other topic areas, such as Education and Quality Improvement and Critical Care, transitioned to greater representation of women in recent years. CONCLUSIONS: There has been an increase over time in women moderators selected for participation in the STS Annual Meeting, with progress in gender diversity seen in most session types. Although the overall proportion of women within cardiothoracic surgery remains low, the STS has increasingly worked toward encouraging inclusivity. Efforts to further support well-rounded representation are of important benefit.

Minimally invasive surgery for clinical T4 non-small-cell lung cancer: national trends and outcomes.

OBJECTIVES: Recent randomized data support the perioperative benefits of minimally invasive surgery (MIS) for non-small-cell lung cancer (NSCLC). Its utility for cT4 tumours remains understudied. We, therefore, sought to analyse national trends and outcomes of minimally invasive resections for cT4 cancers. METHODS: Using the 2010-2019 National Cancer Database, we identified patients with cT4N0-1 NSCLC. Patients were stratified by surgical approach. Multivariable logistic analysis was used to identify factors associated with use of a minimally invasive approach. Groups were matched using propensity score analysis to evaluate perioperative and survival end points. RESULTS: The study identified 3715 patients, among whom 64.1% (n = 2381) underwent open resection and 35.9% (n = 1334) minimally invasive resection [robotic-assisted in 31.5% (n = 420); and video-assisted in 68.5% (n = 914)]. Increased MIS use was noted among patients with higher income [≥$40 227, odds ratio (OR) 1.24; 95% confidence interval (CI) 1.01-1.51] and those treated at academic hospitals (OR 1.25; 95% CI 1.07-1.45). Clinically node-positive patients (OR 0.68; 95% CI 0.55-0.83) and those who underwent neoadjuvant therapy (OR 0.78; 95% CI 0.65-0.93) were less likely to have minimally invasive resection. In matched groups, patients undergoing MIS had a shorter median length of stay (5 vs 6 days, P < 0.001) and no significant differences between 30-day readmissions or 30/90-day mortality. MIS did not compromise overall survival (log-rank P = 0.487). CONCLUSIONS: Nationally, the use of minimally invasive approaches for patients with cT4N0-1M0 NSCLC has increased substantially. In these patients, MIS is safe and does not compromise perioperative outcomes or survival.

Resection of the Primary Tumor and Survival in Patients with Single-Site Synchronous Oligometastatic Non-Small Cell Lung Cancer: Propensity-Matched Analysis of the National Cancer Database.

BACKGROUND: Local therapy for the primary tumor is postulated to remove resistant cancer cells as well as immunosuppressive cells from the tumor microenvironment, potentially improving response to systemic therapy (ST). We sought to determine whether resection of the primary tumor was associated with overall survival (OS) in a multicentric cohort of patients with single-site synchronous oligometastatic non-small cell lung cancer. STUDY DESIGN: Using the National Cancer Database (2018 to 2020), we evaluated patients with clinical stage IVA disease who received ST and stratified the cohort based on receipt of surgery for the primary tumor (S). We used multivariable and propensity score-matched analysis to study factors associated with S (logistic regression) and OS (Cox regression and Kaplan-Meier), respectively. RESULTS: Among 12,215 patients identified, 2.9% (N = 349) underwent S and 97.1% (N = 11,886) ST (chemotherapy or immunotherapy) without surgery. Patients who underwent S were younger, more often White, had higher income levels, were more likely to have private insurance, and were more often treated at an academic facility. Among those who received S, 22.9% (N = 80) also underwent resection of the distant metastatic site. On multivariable analysis, metastasis to bone, N+ disease, and higher T-stages were independently associated with less S. On Cox regression, S and resection of the metastatic site were associated with improved survival (hazard ratio 0.67, 95% CI 0.56 to 0.80 and hazard ratio 0.80, 95% CI 0.72 to 0.88, respectively). After propensity matching, OS was improved in patients undergoing S (median 36.8 vs 20.8 months, log-rank p < 0.001). CONCLUSIONS: Advances in ST for non-small cell lung cancer may change the paradigm of eligibility for surgery. This study demonstrates that surgical resection of the primary tumor is associated with improved OS in selected patients with single-site oligometastatic disease.

Pneumonectomy for non-small cell lung cancer. A National Cancer Database analysis of geographic and temporal trends, outcomes, and associated factors.

BACKGROUND: The circumstances under which pneumonectomy should be performed are controversial. This study aims to investigate national trends in pneumonectomy use to determine which patients, in what geographic areas, and under what clinical circumstances pneumonectomy is performed in the United States. METHODS: We queried the National Cancer Database and included all patients undergoing anatomic surgical resection for non-small cell lung cancer (2015-2020). The association between demographic and clinical factors and the use of pneumonectomy were investigated. RESULTS: Who: A total of 128,421 patients were identified, of whom 738 (0.6%) underwent pneumonectomy. Those patients were younger (median 65 vs 68 years, P < .001), more often male (59.9% vs 44.9%, P < .001), more likely to be below median income level (44.2% vs 38.6%, P = .002), and more likely to have lower education indicators (53% vs 48.6%, P = .02) than those who underwent other anatomic resections. Notably, there was a decreasing trend in pneumonectomy use during the study period (0.9% down to 0.4%, P < .001). Where: Patients undergoing pneumonectomy were less likely to live in metropolitan areas (77.9% vs 81.7%, P = .008) and to live closer (<12 miles) to their treating facility (45% vs 49%, P = .02). Regional geographic differences also were identified (P < .001). Why: Patients who underwent pneumonectomy were more likely to have received neoadjuvant therapy (20.6% vs 5.3%, P < .001), to be clinically N (+) (39.3% vs 12.3%, P < .001), and to have more advanced tumors (cT3-4: 46.3% vs 11.3%, P < .001). CONCLUSION: Although primarily driven by advanced oncologic features, socioeconomic and geographic factors also were associated independently with the use of pneumonectomy. Standardizing pneumonectomy indications nationwide is crucial to prevent widening outcome gaps for patients with lung cancer.

Based on our collective experiences, we aim to highlight program attributes that applicants should consider to find their perfect match.

Is underutilization of adjuvant therapy in resected non-small-cell lung cancer associated with socioeconomic disparities?

OBJECTIVES: Although adjuvant systemic therapy (AT) has demonstrated improved survival in patients with resected non-small-cell lung cancer (NSCLC), it remains underutilized. Recent trials demonstrating improved outcomes with adjuvant immunotherapy and targeted treatment imply that low uptake of systemic therapy in at-risk populations may widen existing outcome gaps. We, therefore, sought to determine factors associated with the underutilization of AT. METHODS: The National Cancer Database (2010-2018) was queried for patients with completely resected stage II-IIIA NSCLC and stratified based on the receipt of AT. Logistic regression was used to identify factors associated with AT delivery. The Kaplan-Meier method was applied to estimate survival after propensity-matching to adjust for confounders. RESULTS: Of 37 571 eligible patients, only 20 616 (54.9%) received AT. While AT rates increased over time, multivariable analysis showed that older age [adjusted odds ratio (aOR) 0.45, 95% confidence interval (CI) 0.43-0.47], male sex (aOR 0.88, 95% CI 0.85-0.93) and multiple comorbidities (aOR 0.86, 95% CI: 0.81-0.91) were associated with decreased AT. Socioeconomic factors were additionally associated with underutilization, including public insurance (aOR 0.70, 95% CI: 0.66-0.74), lower education indicators (aOR 0.93, 95% CI: 0.88-0.97) and living more than 10 miles from a treatment facility (aOR 0.89, 95% CI: 0.85-0.93). After propensity matching, receipt of adjuvant therapy was associated with improved overall survival (median 76.35 vs 47.57 months, P ≤ 0.001). CONCLUSIONS: AT underutilization in patients with resected stage II-III NSCLC is associated with patient, institutional and socioeconomic factors. It is critical to implement measures to address these inequities, especially in light of newer adjuvant immunotherapy and targeted therapy treatment options which are expected to improve survival.

Robotic Resection of Pulmonary Epithelial Myoepithelial Carcinoma: A Case Report.

Background Pulmonary epithelial-myoepithelial carcinoma (P-EMC) is an extremely rare, well-differentiated, and malignant neoplasm originating from submucosal bronchial glands in the lung. EMCs arise mainly in the salivary glands. Case Description This case represents an asymptomatic 78-year-old male with a remote 75-pack-year history of smoking who presents with a solitary endobronchial lesion, which is suggestive of a primary lung EMC, detected on annual screening chest computed tomography (CT) scan. Conclusion A recent review of literature reveals less than 50 documented cases of the pulmonary subtype of this tumor worldwide. We are reporting a unique case of robot-assisted pulmonary lobectomy for a P-EMC.
