Patient-reported outcome measures in surgical patients with upper gastrointestinal cancers: A qualitative interview study.

Background And Objectives: Patients with pancreatic and gastroesophageal (PGE) cancers experience high symptom burden, but patient experience throughout multimodality treatment remains unclear. We aimed to delineate the experience and symptom burden of patients throughout their perioperative course.

Methods: Qualitative interviews were performed with 17 surgical patients with PGE cancer.

Trends Over Time in Recurrence Patterns and Survival Outcomes after Neoadjuvant Therapy and Surgery for Pancreatic Cancer.

Objective: We aimed to determine if advances in neoadjuvant therapy affected recurrence patterns and survival outcomes after pancreatectomy for pancreatic ductal adenocarcinoma (PDAC).

Background: Data are limited on how modern multimodality therapy affects PDAC recurrence and post-recurrence survival.

Methods: Patients who received neoadjuvant therapy followed by curative-intent pancreatectomy for PDAC during 1998-2018 were identified.

Primary tumor site for localized Merkel cell carcinoma drives different management strategies without impacting oncologic outcomes.

Background And Purpose: Clinically localized Merkel cell carcinoma (MCC) has been associated with high rates of disease relapse. This study examines how primary tumor anatomic site drives patterns of care and outcomes in a large cohort treated in the contemporary era.

Materials And Methods: Patterns of care and associated outcomes were evaluated for clinically Stage I-II MCC patients treated at our institution with adjuvant radiation therapy (RT) to the primary site and/or regional nodal basin as a component of their curative intent therapy between 2014-2021.

The Influence of the Microbiome on Metastatic Colorectal Cancer.

The microbiome (bacteria, viruses, and fungi) that exist within a patient's gastrointestinal tract and throughout their body have been increasingly understood to play a critical role in a variety of disease, including a number of cancer histologies. These microbial colonies are reflective of a patient's overall health state, their exposome, and germline genetics. In the case of colorectal adenocarcinoma, significant progress has been made in understanding the mechanism the microbiome plays beyond mere associations in both disease initiation and progression.

Technique for Robotic Pancreaticojejunostomy.

Background:: Minimally invasive, robotic techniques for hepatobiliary procedures offer the potential for accelerated recovery and reduced opioid usage. Robotic pancreaticoduodenectomy is a technically challenging procedure with a complex reconstruction. In this regard, standardization of the pancreaticojejunostomy technique is critical for safe adoption of robotic technology in pancreatic surgery.

Fluoroscopic Intraoperative Breast Neoplasm and Node Detection.

Background: Preoperative localization is necessary for nonpalpable breast lesions. A novel procedure, fluoroscopic intraoperative neoplasm and node detection (FIND), obviates the preoperative painful and potentially expensive localization by using intraoperative visualization of the standard clip placed during diagnostic biopsy. We hypothesized FIND would improve negative margin rates.

Intestinal toxicity to CTLA-4 blockade driven by IL-6 and myeloid infiltration.

Immune checkpoint blockade (ICB) has revolutionized cancer treatment, yet quality of life and continuation of therapy can be constrained by immune-related adverse events (irAEs). Limited understanding of irAE mechanisms hampers development of approaches to mitigate their damage. To address this, we examined whether mice gained sensitivity to anti-CTLA-4 (αCTLA-4)-mediated toxicity upon disruption of gut homeostatic immunity.

Extracorporeal Membrane Oxygenation for Adult Patients With Neoplasms: Outcomes and Trend Over the Last 2 Decades.

Extracorporeal membrane oxygenation (ECMO) is utilized in the management of severe respiratory and circulatory failure. Advanced malignancy is a relative contraindication, but the indication for ECMO in the oncologic population has not been clearly established because of the wide spectrum of malignant disease and prognoses. The Extracorporeal Life Support Organization database was queried for patients older than 18 years with an International Classification of Diseases code of neoplasm over the past 2 decades (2000-2019).

Extracorporeal Membrane Oxygenation for Patients With Thoracic Neoplasms: An Extracorporeal Life Support Organization (ELSO) Registry Analysis.

Background: Extracorporeal membrane oxygenation (ECMO) is used in the management of severe cardiopulmonary failure, but the indication in the oncologic population has not been clearly established. Among malignant neoplasms, thoracic neoplasms are unique in their potential direct impact on cardiopulmonary function. This study aimed to better define the role of ECMO for thoracic neoplasms.

The Microbiome: the Link to Colorectal Cancer and Research Opportunities.

In recent years, we have seen an increase in the study and interest of the role of the microbiome in the development of malignancies, their progression, and evasion of therapies. This has been particularly fruitful in the case of colorectal cancer; multiple investigators have described correlative observations as well as hypotheses strengthened in preclinical studies that have begun to elucidate the critical role the gut and tumoral microbiome plays in carcinogenesis. Furthermore, these landmark studies lay the groundwork in describing the microbiome's role in carcinogenesis and provide a rich field of future study.

Outcome of Extracorporeal Membrane Oxygenation for Pediatric Patients With Neoplasm: An Extracorporeal Life Support Organization Database Study (2000-2019).

Objectives: This study update in usage and outcomes of pediatric extracorporeal membrane oxygenation (ECMO) for patients with neoplasm analyzed according to demographics, clinical variables, and complications.

Design: Retrospective database review of the Extracorporeal Life Support Organization registry from the last 2 decades (2000-2019). The data were divided between two decades in order to compare patients' backgrounds and outcomes over time.

Novel Ex Vivo Model to Examine the Mechanism and Relationship of Esophageal Microbiota and Disease.

Rates of esophageal cancer have increased over the last 40 years. Recent clinical research has identified correlations between the esophageal microbiome and disease. However, mechanisms of action have been difficult to elucidate performing human experimentation.

A large national comparative study of clinicopathological features and long-term survivals between esophageal gastrointestinal stromal tumor and leiomyosarcoma.

Background: Esophageal gastrointestinal stromal tumors (E-GIST) and leiomyosarcoma (E-LMS) are rare tumors. Previous studies are limited to small number of patients. We sought to study these two tumors using a large national database.

Use of a Mobile Intraoperative Computed Tomography Scanner for Navigation Registration During Laser Interstitial Thermal Therapy of Brain Tumors.

Objective: In recent years laser interstitial thermal therapy (LITT) has become the ablative neurosurgical procedure of choice. Multiple methods for registration and laser fiber verification have been described, with each method requiring multiple steps and significant time expenditure. We evaluated the use of a commercially available mobile computed tomography (CT) scanner for stereotactic registration during LITT for brain tumors in an attempt to simplify the procedure and improve intraoperative awareness of laser position.
