A Modified Floxuridine Reduced-Dose Protocol for Patients with Unresectable Colorectal Liver Metastases Treated with Hepatic Arterial Infusion.

Background: Most patients treated with the standard dosing protocol (SDP) of hepatic arterial infusion (HAI) floxuridine require dose holds and reductions, thereby limiting their HAI therapy. We hypothesized that a modified dosing protocol (MDP) with a reduced floxuridine starting dose would decrease dose holds, dose reductions, and have similar potential to convert patients with unresectable colorectal liver metastases (uCRLM) to resection.

Patients And Methods: We reviewed our institutional database of patients with uCRLM treated with HAI between 2016 and 2022.

Safety and Effectiveness of Portal Vein Embolization after Hepatic Arterial Infusion Therapy.

Portal vein embolization (PVE) is a tool potentially useful for inducing future liver remnant (FLR) hypertrophy in patients with advanced hepatic malignancies who are at high risk of hepatic insufficiency if treated with surgical resection. However, the safety and effectiveness of PVE in the context of patients who have undergone hepatic arterial infusion (HAI) are unknown. This retrospective, single-center study identified 9 patients who underwent PVE after HAI between January 2015 and December 2022.

Clinician overconfidence in visual estimation of the posthepatectomy liver remnant volume: A proximal source of liver failure after major hepatic resection?

Background: Post-hepatectomy liver failure is a source of morbidity and mortality after major hepatectomy and is related to the volume of the future liver remnant. The accuracy of a clinician's ability to visually estimate the future liver remnant without formal computed tomography liver volumetry is unknown.

Methods: Twenty physicians in diagnostic radiology, interventional radiology, and hepatopancreatobiliary surgery reviewed 20 computed tomography scans of patients without underlying liver pathology who were not scheduled for liver resection.

The Hallmarks of Circulating Hybrid Cells.

While tumor metastases represent the primary driver of cancer-related mortality, our understanding of the mechanisms that underlie metastatic initiation and progression remains incomplete. Recent work identified a novel tumor-macrophage hybrid cell population, generated through the fusion between neoplastic and immune cells. These hybrid cells are detected in primary tumor tissue, peripheral blood, and in metastatic sites.

Updated Management of Colorectal Cancer Liver Metastases: Scientific Advances Driving Modern Therapeutic Innovations.

Colorectal cancer is the second leading cause of cancer-related deaths in the United States and accounts for an estimated 1 million deaths annually worldwide. The liver is the most common site of metastatic spread from colorectal cancer, significantly driving both morbidity and mortality. Although remarkable advances have been made in recent years in the management for patients with colorectal cancer liver metastases, significant challenges remain in early detection, prevention of progression and recurrence, and in the development of more effective therapeutics.

The genomics of liver metastases from colon and rectal cancer: An Invited Commentary (invitation from Lee Ocuin, MD and Kevin Behrns, MD) for the special issue of "Management of Advanced Primary and Secondary Liver Malignancies".

Over the past two decades, the treatment of patients with cancer has become increasingly structured around the identification of cancer mutations genetically driving the disease. Upfront knowledge of these data has implications for both the selection and omission of certain cytotoxic and targeted therapies. For patients with colon or rectal cancer metastatic to the liver, next-generation sequencing to identify these key mutational drivers should be done at the outset of diagnosis to understand the full spectrum of treatment options available to a patient.

Neoadjuvant therapy does not impact the biliary microbiome in patients with pancreatic cancer.

Background: Pancreatic adenocarcinoma (PDAC) often impinges on the biliary tree and obstruction necessitates stent placement increasing the risk of surgical site infections (SSIs). We sought to explore the impact of neoadjuvant therapy on the biliary microbiome and SSI risk in patients undergoing resection.

Methods: A retrospective analysis was performed on 346 patients with PDAC who underwent resection at our institution from 2008 to 2021.

Referral and treatment patterns in pancreatic acinar cell carcinoma: A regional population-level analysis.

Background: Pancreatic acinar cell carcinoma (PACC) is a rare exocrine tumor of the pancreas. We evaluated the effect disease stage, surgical intervention, and institutional volume status plays in survival.

Methods: We queried the Oregon State Cancer Registry for patients with PACC from 1997 to 2018.

Care at high-volume centers is associated with improved outcomes for patients with pancreatic neuroendocrine tumors: A population-level analysis.

Background And Objectives: Primary resection and debulking of liver metastases have been associated with improved survival in pancreatic neuroendocrine tumors (PNETs). The treatment patterns and outcomes differences between low-volume (LV) institutions and high-volume (HV) institutions remains unstudied.

Methods: A statewide cancer registry was queried for patients with nonfunctional PNET from 1997 to 2018.

Delayed adjuvant endocrine therapy is associated with decreased recurrence-free survival following neoadjuvant chemotherapy for breast cancer.

Background: In hormone receptor-positive breast cancer (HRPBC), endocrine therapy is often initiated after adjuvant radiotherapy given concerns of radiation fibrosis. No studies have investigated how this may impact outcomes in high-risk patients undergoing neoadjuvant chemotherapy (NAC).

Methods: Females with nonmetastatic HRPBC receiving NAC from 2011 to 2017 were identified from our multi-institutional database.

High-volume centers are associated with higher receipt of combined therapy in stage III pancreatic cancer.

Background: Pancreatic ductal adenocarcinoma (PDAC) is often diagnosed at a locally advanced stage with vascular involvement which was previously viewed as a contraindication to resection. However, high-volume centers are increasingly capable of resecting complex tumors. We aimed to explore patterns of treatment that are uncharacterized on a population level.

The need for integrated clinical and administrative data models for risk adjustment in assessment of the cost transplant care.

Introduction: Value-based purchasing requires accurate techniques to appropriately measure both outcomes and cost with robust adjustment for differences in severity of illness. Traditional methods to adjust cost estimates have exclusively used administrative data derived from billing claims to identify comorbidity and complications. Transplantation uniquely has accurate national clinical registry data that can be used to supplement administrative data.

Technology-Enabled Care and Artificial Intelligence in Kidney Transplantation.

Purpose Of Review: Artificial intelligence (AI), machine learning, and technology-enabled remote patient care have evolved rapidly and have now been incorporated into many aspects of medical care. Transplantation is fortunate to have large data sets upon which machine learning algorithms can be constructed. AI are now available to improve pretransplant management, donor selection, and post-operative management of transplant patients.

A simple risk-based reimbursement system for kidney transplant.

Transplant centers were challenged by the Executive Order on Advancing Kidney health to increase access to kidney transplant (KTx) by accepting higher risk patients and organs. However, Medicare reimbursement for KTx does not include adjustment for major complicating comorbidities (MCCs) like other transplants. The prevalence of MCCs was assessed for KTx performed from 10/15 to 10/19 at a single academic center, using Medicare ICD10 MCC criteria exclusive of end-stage kidney disease.
