Conditional Survival of Patients With Early-Stage Non-Small Cell Lung Cancer Who Undergo Lobectomy, Segmentectomy, or Wedge Resection Using the NCDB.

Background And Objectives: Randomized clinical trials have shown that sub-lobar resection for clinical stage (cStage) IA non-small cell lung cancer (NSCLC) is non-inferior to lobar resection. We evaluated traditional and conditional survival differences between lobectomy, wedge resection, and segmentectomy in patients with cStage IA NSCLC.

Methods: The National Cancer Database (2004-2019) was queried for patients with cStage IA (≤ 2 cm) NSCLC who underwent upfront lobectomy, segmentectomy, or wedge resection.

Impact of select actionable genomic alterations on efficacy of neoadjuvant immunotherapy in resectable non-small cell lung cancer.

Background: Neoadjuvant immune checkpoint inhibitors (ICIs) have improved survival outcomes compared with chemotherapy in resectable non-small cell lung cancer (NSCLC). However, the impact of actionable genomic alterations (AGAs) on the efficacy of neoadjuvant ICIs remains unclear. We report the influence of AGAs on treatment failure (TF) in patients with resectable NSCLC treated with neoadjuvant ICIs.

Relationship of Surgical Approach With Financial Toxicity in Patients With Resected Lung Cancer.

Introduction: Minimally invasive surgery (MIS) reduces lengths of stay, complications, and potentially perioperative hospital costs. However, the impact of MIS on financial toxicity (FT), defined as the costs resulting from oncologic care and their negative effects on quality of life, in patients with lung cancer is unknown. Our objective was to investigate the association between surgical approach and FT in this population.

Signet ring cells and conditional survival after trimodality therapy for esophageal adenocarcinoma.

Background And Methods: Although signet ring cell (SRC) histology is associated with resistance to neoadjuvant chemoradiotherapy and worse overall survival (OS) in esophageal adenocarcinoma (EAC), its prognostic relationship among patients who survive the early period following resection is unknown. EAC patients who underwent trimodality therapy at a single institution (2006-2018) were identified. Bayesian multivariable regression (BMR) analyses of OS and additional OS from a 3-year landmark were performed.

Pulmonary Surgical Margins for Metastatic Osteosarcoma: Is Negative Margin Enough?

Background: In advanced osteosarcoma, the lung is the most frequent site of distant metastasis, with metastasectomy often used for local disease control. The influence of pulmonary resection margin length on outcomes for osteosarcoma has not been well explored. This study sought to evaluate the impact of margin length relative to tumor size on local recurrence and survival in lung-limited metastatic osteosarcoma.

Enhancing NSCLC recurrence prediction with PET/CT habitat imaging, ctDNA, and integrative radiogenomics-blood insights.

While we recognize the prognostic importance of clinicopathological measures and circulating tumor DNA (ctDNA), the independent contribution of quantitative image markers to prognosis in non-small cell lung cancer (NSCLC) remains underexplored. In our multi-institutional study of 394 NSCLC patients, we utilize pre-treatment computed tomography (CT) and F-fluorodeoxyglucose positron emission tomography (FDG-PET) to establish a habitat imaging framework for assessing regional heterogeneity within individual tumors. This framework identifies three PET/CT subtypes, which maintain prognostic value after adjusting for clinicopathologic risk factors including tumor volume.

Early Interventional Treatment of High Output Chyle Leak After Esophagectomy is Associated With Improved Survival.

Objective: To investigate overall survival and length of stay (LOS) associated with differing management for high output (>1 L over 24 hours) leaks (HOCL) after cancer-related esophagectomy.

Background: Although infrequent, chyle leak after esophagectomy is an event that can lead to significant perioperative sequelae. Low-volume leaks appear to respond to nonoperative measures, whereas HOCLs often require invasive therapeutic interventions.

Synthetic PET from CT improves diagnosis and prognosis for lung cancer: Proof of concept.

[F]Fluorodeoxyglucose positron emission tomography (FDG-PET) and computed tomography (CT) are indispensable components in modern medicine. Although PET can provide additional diagnostic value, it is costly and not universally accessible, particularly in low-income countries. To bridge this gap, we have developed a conditional generative adversarial network pipeline that can produce FDG-PET from diagnostic CT scans based on multi-center multi-modal lung cancer datasets (n = 1,478).

Octreotide's role in the management of post-esophagectomy chylothorax.

The use of octreotide in managing intrathoracic chyle leak following esophagectomy has gained popularity in the adult population. While the benefits of octreotide have been confirmed in the pediatric population, there remains limited evidence to support its use in the adults post-esophagectomy. Thus, we performed a single-institution cohort study to characterize its efficacy.

Circulomic variables predict pathologic staging preoperatively in treatment-naïve non-small cell lung cancer.

Background: Therapeutic decisions in non-small cell lung cancer (NSCLC) are stage-dependent, and, consequently, changes in an individual's stage carry potential for substantial alterations in management. Malignancy-related disturbances of the circulomic inflammatory environment may affect platelets quantitatively, ultimately leading to changes in tumor characteristics. Our objective was to identify circulomic characteristics associated with upstaging among chemotherapy-naïve patients with resected NSCLC and to assess the consequent impact on overall survival (OS).

Do resected colorectal cancer patients need early chest imaging? Impact of clinicopathologic characteristics on time to development of pulmonary metastases.

Background And Objectives: For patients with colorectal cancer (CRC), the lung is the most common extra-abdominal site of distant metastasis. However, practices for chest imaging after colorectal resection vary widely. We aimed to identify characteristics that may indicate a need for early follow-up imaging.

Surgical outcomes after chemotherapy plus nivolumab and chemotherapy plus nivolumab and ipilimumab in patients with non-small cell lung cancer.

Objective: Chemotherapy plus nivolumab is the standard of care neoadjuvant treatment for patients with resectable stage IB to IIIA non-small cell lung cancer. The influence of dual checkpoint blockade with chemotherapy on surgical outcomes remains unknown. We aimed to determine operative complexity and perioperative outcomes associated with neoadjuvant chemotherapy and nivolumab with or without ipilimumab.

Association of Preoperative Lung Function with Complications after Lobectomy Using Race-Neutral and Race-Specific Normative Equations.

Pulmonary function testing (PFT) is performed to aid patient selection before surgical resection for non-small cell lung cancer (NSCLC). The interpretation of PFT data relies on normative equations, which vary by race, but the relative strength of association of lung function using race-specific or race-neutral normative equations with postoperative pulmonary complications is unknown. To compare the strength of association of lung function, using race-neutral or race-specific equations, with surgical complications after lobectomy for NSCLC.

Activity of pazopanib in translocation-associated bone sarcoma.

Pazopanib is a multi-kinase inhibitor that is currently approved for treatment of advanced renal cell carcinoma and chemotherapy-refractory soft tissue sarcoma. In this case report, we discuss the case of a patient with a fusion positive bone sarcoma who had exceptional tumor control through using pazopanib and surgery for an overall duration exceeding 5 years. We also review the literature on translocation-associated sarcomas and use of pazopanib in bone sarcomas.

Impact of travel distance on receipt of indicated adjuvant therapy in resected non-small cell lung cancer.

Objective: We have previously demonstrated the negative impact of travel distance on adherence to surveillance imaging guidelines for resected non-small cell lung cancer (NSCLC). The influence of patient residential location on adherence to recommended postoperative treatment plans remains unclear. We sought to characterize the impact of travel distance on receipt of indicated adjuvant therapy in resected NSCLC.

Factors associated with receipt of pulmonary metastasectomy in patients with lung-limited metastatic colorectal cancer: Disparities in care and impact on overall survival.

Objectives: Pulmonary metastasectomy (PM) for colorectal cancer may provide respite from systemic therapy and prolonged disease-free intervals. We sought to identify factors associated with PM and to characterize the differential impact on overall survival for those offered lung resection.

Methods: The National Cancer Database was queried for stage IV colorectal cancer patients with lung-limited metastatic disease between 2010 and 2016.

Brief Report: Clinical Response, Toxicity, and Resistance Mechanisms to Osimertinib Plus MET Inhibitors in Patients With EGFR-Mutant MET-Amplified NSCLC.

Introduction: amplification is a known resistance mechanism to tyrosine kinase inhibitor (TKI) treatment in -mutant NSCLC. Dual EGFR-MET inhibition has been reported with success in overcoming such resistance and inducing clinical benefit. Resistance mechanisms to dual EGFR-MET inhibition require further investigation and characterization.

Perioperative and oncologic outcomes of pulmonary resection for synchronous oligometastatic non-small cell lung cancer: Evidence for surgery in advanced disease.

Objectives: Recent randomized trials have demonstrated a survival advantage with the use of local consolidative therapy in oligometastatic non-small cell lung cancer; however, the indications for and outcomes after pulmonary resection as a component of local consolidative therapy remain ill defined. We sought to characterize the perioperative and long-term survival outcomes among patients with resected oligometastatic non-small cell lung cancer.

Methods: Patients presenting to a single center (2000-2017) with oligometastatic non-small cell lung cancer (≤3 synchronous metastases, intrathoracic nodal disease counted as a single site) who underwent resection of the primary tumor were retrospectively identified.

Removing Implicit Bias From Cardiothoracic Surgery Resident Recruitment: Changing the Paradigm.

Introduction: The cardiothoracic (CT) surgery workforce continues to suffer from underrepresentation of women and minority physicians. The presence of implicit bias in the recruitment process may impair efforts to enhance the diversity of our training programs. Using a systematic approach, we aimed to investigate and optimize our candidate selection processes to minimize implicit bias.

Lung surveillance following colorectal cancer pulmonary metastasectomy: Utilization of clinicopathologic risk factors to guide strategy.

Background: Appropriately selected patients clearly benefit from resection of colorectal cancer (CRC) pulmonary metastases (PMs). However, there remains equipoise surrounding optimal chest surveillance strategies following pulmonary metastasectomy. We aimed to identify risk factors that may inform chest surveillance in this population.
