The surgical management of gastric cancer has changed significantly from the first open partial gastrectomy in 1881 to contemporary minimally invasive approaches. The approach has shifted from open surgeries to laparoscopic and robotic-assisted gastrectomies, with evidence of reduced pain, quicker recovery, and lower morbidity with these methods. Multiple randomized trials have confirmed that laparoscopic surgeries yield oncologically safe results.

Despite the availability of various frailty tools, surgeons often make subjective assessments of patients' ability to tolerate surgery. The Risk Analysis Index (RAI) is a validated preoperative frailty assessment tool that has not been studied in cancer patients with plans for curative-intent surgery.

Although local tumor control rates seem encouraging, large-scale survival data comparing SBRT to surgical resection are lacking. We identified patients with stage I/II HCC from the National Cancer Database amenable for potential surgical resection.
View Article and Find Full Text PDFIntroduction: There is no consensus regarding the role of primary tumor resection for patients with metastatic pancreatic neuroendocrine tumors (panNET). We assessed surgical treatment patterns and evaluated the survival impact of primary tumor resection in patients with metastatic panNET.
Methods: Patients with synchronous metastatic nonfunctional panNET in the National Cancer Database (2004-2016) were categorized based on whether they underwent primary tumor resection.
Background: The ideal surveillance strategy after partial pancreatectomy for non-invasive IPMN remains undefined and existing guidelines provide conflicting recommendations. The present study was developed in anticipation of the joint meeting of the International Association of Pancreatology (IAP) and the Japan Pancreas Society (JPS) held in Kyoto in July 2022.
Methods: An international team of experts developed the four clinical questions (CQ) to operationalize issues pertaining to surveillance of patients in this context.
Background: Time to treatment (TTT) varies widely for patients with gastric cancer. We aimed to evaluate relationships between time to treatment, overall survival (OS), and other surgical outcomes in patients with stage I-III gastric cancer.
Methods: We identified patients with clinical stage I-III gastric cancer who underwent curative-intent gastrectomy within the National Cancer Database (2006-2015) and grouped them by treatment sequence: neoadjuvant chemotherapy or surgery upfront.
Objective: To evaluate long-term oncologic outcomes of patients with stage IV pancreatic ductal adenocarcinoma and to identify survival benchmarks for comparison when considering resection in these patients.
Background: Highly selected cohorts of patients with liver-oligometastatic pancreas cancer have reported prolonged survival after resection. The long-term impact of surgery in this setting remains undefined because of a lack of appropriate control groups.
Background: Adherence to evidence-based guidelines for gastric cancer is low, particularly at the hospital level, despite a strong association with improved overall survival (OS). We aimed to evaluate patterns of hospital and regional adherence to National Comprehensive Cancer Network guidelines for gastric cancer.
Methods: Using the National Cancer Database (2004-2015), we identified patients with stage I-III gastric cancer.
Introduction: Surgery is an option for symptom palliation in patients with metastatic gastric cancer. Operative outcomes after palliative interventions are largely unknown. Herein, we assess the trends of surgical palliation use for patients with gastric cancer and describe outcomes of patients undergoing surgical palliation compared to nonsurgical palliation.

Methods: Patients diagnosed with primary GA eligible for DL were identified from the US Safety Net Collaborative database (2012-2014).
Background: National Comprehensive Cancer Network guidelines recommend resection and adjuvant chemotherapy for patients with locally advanced duodenal adenocarcinoma. Outcomes after systemic treatment in this rare malignancy have not been well studied. We examined utilization patterns of systemic treatment and compared overall survival of patients receiving neoadjuvant therapy, surgery alone, and adjuvant therapy.
View Article and Find Full Text PDFBackground: Consensus guidelines discourage resection of poorly differentiated pancreatic neuroendocrine carcinoma (panNEC) given its association with poor long-term survival. This study assessed treatment patterns and outcomes for this rare malignancy using the National Cancer Database (NCDB).
Methods: Patients with non-functional pancreatic neuroendocrine tumors in the NCDB (2004-2016) were categorized based on pathologic differentiation.
Minimally invasive liver resection (MILR) is increasingly used as a surgical treatment for patients with hepatocellular carcinoma (HCC). However, there is no large scale data to compare the effectiveness of MILR in comparison to open liver resection (OLR). We identified patients with stage I or II HCC from the National Cancer Database using propensity score matching techniques.
View Article and Find Full Text PDFBackground: Hispanic patients have a higher incidence of gastric cancer when compared to non-Hispanics. Outlining clinicodemographic characteristics and assessing the impact of ethnicity on stage-specific survival may identify opportunities to improve gastric cancer care for this population.
Methods: Patients with gastric cancer in the US Safety Net Collaborative (2012-2014) were retrospectively reviewed.
Background: Low central venous pressure (LCVP) anesthesia reduces blood loss during hepatic resection and historically has required a central venous catheter (CVC) for intra-operative monitoring. The aim of this study was to assess the effect of an evolution of practice to CVP monitoring without CVC on the perioperative outcomes after liver resection.
Methods: A retrospective study of partial hepatectomy patients from 2007 to 2016 who were over 18 years of age was performed.
Background: MicroRNAs (miRNAs) are potential biomarkers in various malignancies. We aim to characterize miRNA expression in intrahepatic cholangiocarcinoma (ICC) and identify circulating plasma miRNAs with potential diagnostic and prognostic utility.
Methods: Using deep-sequencing techniques, miRNA expression between tumor samples and non-neoplastic liver parenchyma were compared.
Objective: The aim of the present study is to determine if CEACAM6 can be detected in the bile of patients with biliary cancer and can serve as a diagnostic biomarker for cholangiocarcinoma.
Summary Background Data: Distinguishing bile duct carcinoma from other diagnoses is often difficult using endoscopic or percutaneous techniques. The cell surface protein CEACAM6 is over-expressed in many gastrointestinal cancers and may be selectively elevated in biliary adenocarcinoma.
Background: The optimal perioperative fluid resuscitation strategy for liver resections remains undefined. Goal-directed therapy (GDT) embodies a number of physiologic strategies to achieve an ideal fluid balance and avoid the consequences of over- or under-resuscitation.
Study Design: In a prospective randomized trial, patients undergoing liver resection were randomized to GDT using stroke volume variation as an end point or to standard perioperative resuscitation.
Background: The prognostic and predictive abilities of 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) coupled with conventional computed tomography (CT) have not been studied in patients with unresectable colorectal liver metastases (uCRLM) treated with combined hepatic arterial infusion (HAI) and systemic chemotherapy.
Objectives: The ability of PET-CT metabolic response parameters to predict conversion to resectability and oncologic outcome in this setting was evaluated.
Methods: Thirty-eight patients undergoing serial PET-CT as part of a Phase II trial of HAI and systemic chemotherapy for uCRLM were included.
