Japanese Encephalitis Virus Surveillance in U.S. Army Installations in the Republic of Korea from 2021 to 2023.

Japanese encephalitis is a disease caused by the Japanese encephalitis virus (JEV) and is a concern for U.S. military personnel stationed in the Republic of Korea (ROK).

Circulating KRAS G12D but not G12V is associated with survival in metastatic pancreatic ductal adenocarcinoma.

While high circulating tumor DNA (ctDNA) levels are associated with poor survival for multiple cancers, variant-specific differences in the association of ctDNA levels and survival have not been examined. Here we investigate KRAS ctDNA (ctKRAS) variant-specific associations with overall and progression-free survival (OS/PFS) in first-line metastatic pancreatic ductal adenocarcinoma (mPDAC) for patients receiving chemoimmunotherapy ("PRINCE", NCT03214250), and an independent cohort receiving standard of care (SOC) chemotherapy. For PRINCE, higher baseline plasma levels are associated with worse OS for ctKRAS G12D (log-rank p = 0.

Prediction of Lu-DOTATATE Therapy Outcomes in Neuroendocrine Tumor Patients Using Semi-Automatic Tumor Delineation on Ga-DOTATATE PET/CT.

Background: Treatment of metastatic neuroendocrine tumors (NET) with Lu-DOTATATE peptide receptor radionuclide therapy (PRRT) results in favorable response only in a subset of patients. We investigated the prognostic value of quantitative pre-treatment semi-automatic Ga-DOTATATE PET/CT analysis in NET patients treated with PRRT.

Methods: The medical records of 94 NET patients who received at least one cycle of PRRT at a single institution were retrospectively reviewed.

Neutrophil extracellular traps induced by chemotherapy inhibit tumor growth in murine models of colorectal cancer.

Neutrophil extracellular traps (NETs), a web-like structure of cytosolic and granule proteins assembled on decondensed chromatin, kill pathogens and cause tissue damage in diseases. Whether NETs can kill cancer cells is unexplored. Here, we report that a combination of glutaminase inhibitor CB-839 and 5-FU inhibited the growth of PIK3CA-mutant colorectal cancers (CRCs) in xenograft, syngeneic, and genetically engineered mouse models in part through NETs.

Integrated Capecitabine-Temozolomide with Radioembolization for Liver-Dominant G2 NETs: Long-Term Outcomes of a Single-Institution Retrospective Study.

Purpose: Capecitabine-Temozolomide (CapTem) is an oral chemotherapy regimen for NETs. Both drugs are radiosensitizers. Integrating CapTem and Y90 transarterial radioembolization (TARE) in patients with grade 2 neuroendocrine tumor (NET) liver metastases achieved an encouraging objective response rate (ORR) and progression-free survival (PFS) in a feasibility study.

Poke Plan: An Initiative to Improve Distraction and Pain Mitigation With Venous Access in Hospitalized Children.

Background: Adequate pain control and anxiety relief during peripheral intravenous cannula (PIV) placement improves patient, parental, and staff satisfaction and reduces health care-induced stress in children. We noted a low rate of analgesic/anxiolysis use (<20%) and child life utilization (3%) in our institution. This quality improvement project was initiated to increase pain mitigation strategies in hospitalized children requiring PIV access.

Expert Consensus Practice Recommendations of the North American Neuroendocrine Tumor Society for the management of high grade gastroenteropancreatic and gynecologic neuroendocrine neoplasms.

High-grade neuroendocrine neoplasms are a rare disease entity and account for approximately 10% of all neuroendocrine neoplasms. Because of their rarity, there is an overall lack of prospectively collected data available to advise practitioners as to how best to manage these patients. As a result, best practices are largely based on expert opinion.

Gastroenteropancreatic Neuroendocrine Tumors.

Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are the most common type of neuroendocrine tumors and are being increasingly identified in clinical practice. The diagnosis, staging, management, and surveillance of GEP-NETs rely heavily on endoscopy, and consequently, it is important for gastroenterologists to have a solid understanding of these tumors. This article reviews the presentation, diagnosis, and management of both localized and advanced GEP-NETs, with increased emphasis on the role of endoscopy, to enable gastroenterologists and other practitioners to have the necessary tools for the care of patients with these tumors.

Neoadjuvant immunotherapy of locoregionally advanced solid tumors.

Definitive management of locoregionally advanced solid tumors presents a major challenge and often consists of a combination of surgical, radiotherapeutic and systemic therapy approaches. Upfront surgical treatment with or without adjuvant radiotherapy carries the risks of significant morbidities and potential complications that could be lasting. In addition, these patients continue to have a high risk of local or distant disease relapse despite the use of standard adjuvant therapy.

Multianalyte Prognostic Signature Including Circulating Tumor DNA and Circulating Tumor Cells in Patients With Advanced Pancreatic Adenocarcinoma.

Purpose: Pancreatic ductal adenocarcinoma (PDAC) is associated with a poor prognosis. Multianalyte signatures, including liquid biopsy and traditional clinical variables, have shown promise for improving prognostication in other solid tumors but have not yet been rigorously assessed for PDAC.

Materials And Methods: We performed a prospective cohort study of patients with newly diagnosed locally advanced pancreatic cancer (LAPC) or metastatic PDAC (mPDAC) who were planned to undergo systemic therapy.

Association between timely targeted treatment and outcomes in patients with metastatic HER2-overexpressing gastroesophageal adenocarcinoma.

Background: Timely targeted treatment initiation can be challenging because additional biomarker testing is needed for eligibility. The authors hypothesized that timely targeted treatment improves survival relative to nontimely initiation in metastatic HER2+ gastroesophageal adenocarcinoma (GEA).

Methods: The authors performed a retrospective cohort study of metastatic HER2+ GEA treated with first-line (1L) systemic therapy from January 2011 to December 2017 using a nationwide electronic health record-derived deidentified database.

Evolving standards of care for neoadjuvant and adjuvant therapy in esophageal, gastroesophageal junction, and gastric cncer.

Multimodality therapy, which can include systemic therapy, radiation therapy, and surgery, is the preferred approach for most localized, clinical T2 to T4, and/or node-positive esophageal, gastroesophageal junction, and gastric cancers. The optimal content and sequence of perioperative treatment of patients with different sites of disease and tumor histologic types continue to evolve. This review highlights the current standard-of-care approaches and areas of ongoing clinical research, including biomarker-directed therapy, pertaining to the treatment of esophageal, gastroesophageal junction, and gastric cancers in patients who are candidates for therapy with curative intent.

Combined Quantification of F-FDG and Ga-DOTATATE PET/CT for Prognosis in High-Grade Gastroenteropancreatic Neuroendocrine Neoplasms.

Rationale And Objectives: High-grade gastroenteropancreatic neuroendocrine neoplasms (G3 GEP-NENs) are pathologically classified into well differentiated neuroendocrine tumors (G3 NETs) and poorly differentiated neuroendocrine carcinomas (G3 NECs). Using a novel parameter, we examined the prognostic value of F-FDG and Ga-DOTATATE PET/CT quantification in comparison to pathologic assessment in G3 GEP-NENs.

Materials And Methods: A total of 31 patients with G3 GEP-NENs were reviewed.

Laboratory, Clinical, and Survival Outcomes Associated With Peptide Receptor Radionuclide Therapy in Patients With Gastroenteropancreatic Neuroendocrine Tumors.

Importance: Peptide receptor radionuclide therapy (PRRT) is approved in the US for treatment of gastroenteropancreatic neuroendocrine tumors (NETs), but data on PRRT outcomes within US populations remain scarce.

Objective: To analyze the first 2 years of PRRT implementation at a US-based NET referral center.

Design, Setting, And Participants: This cohort study was conducted using medical records of patients with metastatic NET receiving PRRT from 2018 through 2020 in a NET program at a tertiary referral center.

Adherence to and determinants of guideline-recommended biomarker testing and targeted therapy in patients with gastroesophageal adenocarcinoma: Insights from routine practice.

Background: Anti human epidermal growth factor receptor 2 (anti-HER2) therapy with trastuzumab improves overall survival in patients with advanced, HER2-positive gastroesophageal adenocarcinoma (GEA) and is now incorporated into national guidelines. However, little is known about adherence to and determinants of timely HER2 testing and trastuzumab initiation in routine practice.

Methods: The authors performed a cross-sectional study of patients who had advanced GEA diagnosed between January 2011 and June 2019 in a nationwide electronic health record-derived database.

The efficacy and safety of definitive concurrent chemoradiotherapy for non-operable esophageal cancer.

Objective: To report outcomes and toxicity in patients who received definitive concurrent chemoradiation (DCCRT) for non-operable esophageal cancer (EC) in the modern era, and to identify markers of overall and disease-free survival (OS/DFS).

Methods: We conducted a retrospective cohort study of patients with unresectable EC who received DCCRT at our institution between 1/2008 and 1/2019. Descriptive statistics were used to report disease-control outcomes and CTCAE v4.

Differential Diagnosis of Diarrhea in Patients With Neuroendocrine Tumors.

Patients with neuroendocrine tumors (NETs) and carcinoid syndrome experience diarrhea that can have a debilitating effect on quality of life. Diarrhea also may develop in response to other hormonal syndromes associated with NETs, surgical complications, medical comorbidities, medications, or food sensitivities. Limited guidance on the practical approach to the differential diagnosis of diarrhea in these patients can lead to delays in appropriate treatment.

5-Fluorouracil Enhances the Antitumor Activity of the Glutaminase Inhibitor CB-839 against -Mutant Colorectal Cancers.

encodes the p110α catalytic subunit of PI3K and is frequently mutated in human cancers, including ∼30% of colorectal cancer. Oncogenic mutations in render colorectal cancers more dependent on glutamine. Here we report that the glutaminase inhibitor CB-839 preferentially inhibits xenograft growth of -mutant, but not wild-type (WT), colorectal cancers.

Ga-DOTATATE Positron Emission Tomography-Computed Tomography Quantification Predicts Response to Somatostatin Analog Therapy in Gastroenteropancreatic Neuroendocrine Tumors.

Background: Somatostatin analogs (SSAs) are the frontline antitumor therapy in advanced well-differentiated gastroenteropancreatic neuroendocrine tumors (GEP-NETs). A subset of patients demonstrate early disease progression on SSA therapy, yet the currently known predictors for treatment failure lack specificity to affect therapeutic decision. SSAs target tumor somatostatin receptors, the level of which can be quantitatively assessed with Ga-DOTATATE positron emission tomography-computed tomography (PET/CT).
