Beyond CAR T-Cell Therapy: Continued Monitoring and Management of Complications.

Chimeric antigen receptor (CAR) T-cell therapy has recently emerged as a groundbreaking treatment for CD19-expressing hematologic malignancies and received rapid approval by the U.S. Food & Drug Administration. Tisagenlecleucel and axicabtagene ciloleucel are now widely available at CAR T-cell therapy centers around the United States. Many patients have achieved complete response or remission despite failing multiple previous lines of therapy, but some patients endure the severe risks of cytokine release syndrome, neurotoxicity, and other immunologic effects. As more patients receive this ther

Primary prophylaxis of bacterial infections and Pneumocystis jirovecii pneumonia in patients with hematologic malignancies and solid tumors: 2020 updated guidelines of the Infectious Diseases Working Party of the German Society of Hematology and Medical Oncology (AGIHO/DGHO).

Hematologic and oncologic patients with chemo- or immunotherapy-related immunosuppression are at substantial risk for bacterial infections and Pneumocystis jirovecii pneumonia (PcP). As bacterial resistances are increasing worldwide and new research reshapes our understanding of the interactions between the human host and bacterial commensals, administration of antibacterial prophylaxis has become a matter of discussion. This guideline constitutes an update of the 2013 published guideline of the Infectious Diseases Working Party (AGIHO) of the German Society for Hematology and Medical Oncology

The Gut Microbiota in Hematologic Malignancies: Mechanisms, Clinical Associations, and Translational Opportunities.

Hematologic malignancies arise and progress within a systemic ecosystem in which the gut microbiota is an increasingly recognized, partially modifiable component. Across acute leukemias, chronic lymphocytic leukemia, plasma cell disorders, lymphomas, and clonal myeloid neoplasms, human studies consistently report reduced microbial diversity, depletion of barrier-supportive, short-chain fatty acid-producing commensals, and enrichment of Gram-negative, pro-inflammatory, or hospital-adapted taxa. These alterations are associated with pre-leukemic clonal expansion, adverse genetic and immunologica

The Mechanisms of Altered Blood-Brain Barrier Permeability in CD19 CAR T-Cell Recipients.

Cluster of differentiation 19 (CD19) chimeric antigen receptor (CAR) T cells are a highly effective immunotherapy for relapsed and refractory B-cell malignancies, but their utility can be limited by the development of immune effector cell-associated neurotoxicity syndrome (ICANS). The recent discovery of CD19 expression on the pericytes in the blood-brain barrier (BBB) suggests an important off-target mechanism for ICANS development. In addition, the release of systemic cytokines stimulated by the engagement of CD19 with the CAR T cells can cause endothelial activation and decreased expression

Patient-Caregiver Portal System in Palliative Oncology: Assessment of Usability and Perceived Benefit.

BackgroundThe engagement of family caregivers in oncology is not universal or systematic.ObjectiveWe implemented a process intervention (ie, patient-caregiver portal system) with an existing patient portal system to (1) allow a patient to specify their caregiver and communication preferences with that caregiver, (2) connect the caregiver to a unique caregiver-specific portal page to indicate their needs, and (3) provide an electronic notification of the dyad's responses to the care team to inform clinicians and connect the caregiver to resources as needed.MethodsWe assessed usability and satis

Cardiotoxicity Associated with Anti-CD19 Chimeric Antigen Receptor T-Cell (CAR-T) Therapy: Recognition, Risk Factors, and Management.

Chimeric antigen receptor T-cells (CAR-T) are improving outcomes in pediatric and adult patients with relapsed or refractory B-cell acute lymphoblastic leukemias and subtypes of non-Hodgkin Lymphoma. As this treatment is being increasingly utilized, a better understanding of the unique toxicities associated with this therapy is warranted. While there is growing knowledge on the diagnosis and treatment of cytokine release syndrome (CRS), relatively little is known about the associated cardiac events that occur with CRS that may result in prolonged length of hospital stay, admission to the inten

Systemic Sclerosis and Malignancy: A Review of Current Data.

Systemic sclerosis (SSc) is associated with increased risk of malignancy. The organ systems most commonly affected are the lungs, the breasts and the hematological system. Risk factors predisposing a SSc patient for development of malignancy are not well defined, and the pathogenic basis of the association is yet to be explained. The incidence of malignancies in SSc patients is variable from one report to another, but most importantly, questions regarding the role of immunosuppressive therapies and the effect of autoantibodies have weak or sometimes contradictory answers in most of the current

Поддержка со стороны сверстников в хронических условиях с точки зрения сверстников: систематический обзор.

Цель: Поддержка со стороны сверстников может стать ценным дополнением к обычному уходу за пациентами с хроническими заболеваниями. Хотя выгоды, связанные с поддержкой со стороны сверстников, хорошо задокументированы, в большинстве исследований основное внимание уделяется интересам получателей помощи. Учитывая центральную роль, которую играют сторонники из числа сверстников, их опыт следует рассматривать как не менее важный. В рамках этого систематического обзора обобщается имеющаяся литература, посвященная опыту сочувствующих друг другу лиц с хроническими заболеваниями. Метод: Мы проводили сис

Polyphyllin I Inhibits the Metastasis of Cervical Cancer Through the Regulation of the β-Catenin Signaling Pathway.

Cervical cancer ranks as the fourth most prevalent cancer and cause of cancer-related mortality among women globally. It exhibits a recurrence/metastasis rate of approximately 30% and a dismal 5-year survival of only 17% in metastatic cases. Despite significant advancements in surgical techniques, chemoradiotherapy, and targeted therapies, effective treatment options for metastatic cervical cancer remain limited. This study explored Polyphyllin I (PPI), which is a monomeric compound derived from the Rhizoma of Paris Polyphyllin, as a potential inhibitor of cervical cancer metastasis. Mechanist

What Cardiologists Should Know About Amyloidosis.

Background: Cardiac amyloidosis (CA) is an increasingly recognized but historically underdiagnosed cause of restrictive cardiomyopathy and heart failure with preserved ejection fraction (HFpEF). It results from the extracellular deposition of misfolded protein fibrils, most commonly transthyretin (ATTR) or immunoglobulin light chains (AL), leading to progressive myocardial dysfunction and multi-organ involvement. Objective: This review provides a comprehensive, cardiology-centered overview of cardiac amyloidosis, with an emphasis on early recognition, diagnostic strategies, subtype differentia

Многофункциональная роль аполипопротеина Е в нейродегенеративных заболеваниях.

Генетическое разнообразие в гене аполипопротеина Е (АпоЭ) было определено в качестве основного фактора риска уязвимости в плане генетического риска для спорадического заболевания Альцгеймера (САД). В частности, аллея АпоЕ4 является важным фактором риска для SAD, в то время как аллея АпоЕ2 обеспечивает защиту по сравнению с более распространенными аллеями АпоЕ3. В настоящем обзоре рассматривается роль АпоЭ в АД и других нейродегенеративных расстройствах. ApoE — белок переноса холестерина — влияет на несколько путей нейродегенерации, особенно в AD. Помимо своей установленной роли в метаболизме и

Prevalence of unmet supportive care needs reported by individuals ever diagnosed with cancer in Australia: a systematic review to support service prioritisation.

PurposeImproved health outcomes for individuals ever diagnosed with cancer require comprehensive, coordinated care that addresses their supportive care needs. Implementing interventions to address these is confounded by a lack of evidence on population needs and a large pool of potential interventions. This systematic review estimates the point prevalence of different supportive care needs stratified by the tool used to measure needs and cancer type in Australia.MethodsWe searched MEDLINE, Embase, and Scopus from 2010 to April 2023 to identify relevant studies published on the prevalence of su

A multicountry ecological study of cancer incidence rates in 2008 with respect to various risk-modifying factors.

Observational and ecological studies are generally used to determine the presence of effect of cancer risk-modifying factors. Researchers generally agree that environmental factors such as smoking, alcohol consumption, poor diet, lack of physical activity, and low serum 25-hdyroxyvitamin D levels are important cancer risk factors. This ecological study used age-adjusted incidence rates for 21 cancers for 157 countries (87 with high-quality data) in 2008 with respect to dietary supply and other factors, including per capita gross domestic product, life expectancy, lung cancer incidence rate (an

Drug repurposing in oncology: Compounds, pathways, phenotypes and computational approaches for colorectal cancer.

The strategy of using existing drugs originally developed for one disease to treat other indications has found success across medical fields. Such drug repurposing promises faster access of drugs to patients while reducing costs in the long and difficult process of drug development. However, the number of existing drugs and diseases, together with the heterogeneity of patients and diseases, notably including cancers, can make repurposing time consuming and inefficient. The key question we address is how to efficiently repurpose an existing drug to treat a given indication. As drug efficacy rem

Charting the Current Landscape and Future Prospects of Cancer Therapy-Related Cardiovascular Toxicity in Cancer Survivors: From Bench to Bedside.

Cardio-oncology represents an emerging interdisciplinary discipline focusing on optimizing oncologic efficacy while mitigating treatment-related cardiovascular complications. The advent of novel anticancer agents such as targeted therapies, immune checkpoint inhibitors, and endocrine therapies has transformed cancer care, significantly improving survival rates. Nevertheless, prolonged patient survivorship has unmasked clinically significant cardiovascular sequelae, termed cancer therapy-related cardiovascular toxicity (CTR-CVT), which manifests as acute manifestations during therapy and delaye

Canine Multicentric Lymphoma: Diagnostic, Treatment, and Prognostic Insights.

Lymphoma accounts for 24% of all documented canine neoplasms and 85% of hematological malignancies, while multicentric lymphoma corresponds to 84% of all canine lymphomas. Canine lymphomas of B-cell origin account for 60% to 80% of lymphomas. Similar to humans, the histologic grade, architecture, as well as immunophenotype determination, are crucial. These lesions are the most prevalent spontaneous tumors in dogs and this species may be a valuable animal model for the study of human non-Hodgkin's lymphoma. Therefore, it is important to investigate and assess therapeutic responses and to seek p

Cancer, immune suppression and Coronavirus Disease-19 (COVID-19): Need to manage drug safety (French Society for Oncology Pharmacy [SFPO] guidelines).

The Coronavirus disease (COVID-19) pandemic is disrupting our health environment. As expected, studies highlighted the great susceptibility of cancer patients to COVID-19 and more severe complications, leading oncologists to deeply rethink patient cancer care. This review is dedicated to the optimization of care pathways and therapeutics in cancer patients during the pandemic and aims to discuss successive issues. First we focused on the international guidelines proposing adjustments and alternative options to cancer care in order to limit hospital admission and cytopenic treatment in cancer p

The Biogenesis and Functions of piRNAs in Human Diseases.

Piwi-interacting RNAs (piRNAs) are a novel type of small noncoding RNAs, which are 26-30 nt in length and bind to Piwi proteins. These short RNAs were originally discovered in germline cells and are considered as key regulators for germline maintenance. A growing body of evidence has now extended our views into piRNA biological significance showing that they can also regulate gene expression in somatic cells through transposon silencing, epigenetic programming, DNA rearrangements, mRNA turnover, and translational control. Mounting studies have revealed that the dysregulation of piRNAs may caus

Next-generation antibody-based therapeutics in cancer: antibody-drug conjugates bispecific antibodies across hematologic malignancies and solid tumors.

The therapeutic paradigm in oncology is undergoing a profound transformation driven by antibody-drug conjugates (ADCs) and bispecific antibodies (bsAbs). This review comprehensively summarizes recent clinical advances of these platforms across both hematologic malignancies and solid tumors. ADCs such as trastuzumab deruxtecan have expanded the concept of targetable HER2 expression, demonstrating meaningful intracranial activity and redefining standards of care in HER2-low breast cancer and beyond. The landscape continues to broaden with novel ADC targets (TROP2, CLDN18.2, B7-H3, HER3) and bisp
