    Agentic AI Systems May Transform Nutritional Care in Oncology

    BUFFALO, NY – May 11, 2026 – A new #editorial was #published in Volume 17 of Oncotarget on May 4, 2026, titled “Artificial intelligence in nutritional oncology: From isolated screening tools to agentic intervention systems.” The editorial was authored by first author Arnab Sarkar and corresponding author Yashbir Singh-Wolkenhauer, who is affiliated with the Mayo Clinic Department of Radiology. In this editorial, the authors examine how emerging forms of artificial intelligence may help address one of oncology’s most persistent yet underrecognized challenges: cancer-related malnutrition. Although nutritional complications affect a large proportion of cancer patients and are associated with poorer treatment tolerance, prolonged hospitalizations, and reduced survival, access to specialized nutritional care remains severely limited in many healthcare settings. The article focuses on the growing role of “agentic AI,” a new class of autonomous AI systems capable of reasoning across complex clinical information, using external tools, maintaining memory, and adapting to changing patient conditions over time. Unlike conventional AI tools that perform isolated tasks such as malnutrition screening or dietary counseling, agentic AI systems are designed to coordinate multiple functions simultaneously and support ongoing clinical decision-making throughout a patient’s treatment course. “Where a conventional model answers the question “Is this patient malnourished?”, an agentic system pursues the goal ‘Optimize this patient’s nutritional status throughout their treatment course,’ autonomously decomposing that objective into sensing, reasoning, and acting steps.” The authors outline a proposed multi-agent framework for nutritional oncology that includes specialized AI agents responsible for nutritional screening, dietary planning, treatment-nutrition interaction monitoring, and patient engagement. These agents would operate together under a centralized coordination system capable of integrating laboratory data, imaging findings, treatment-related side effects, food preferences, wearable device data, and electronic health records in real time. The proposed architecture is illustrated in Figure 1 of the paper (page 2), which depicts how multiple AI agents could coordinate patient-centered nutritional support across oncology workflows. Importantly, the editorial emphasizes that clinical oversight remains essential. The authors propose a graduated autonomy model in which lower-risk functions, such as recipe recommendations or symptom-triggered dietary advice, may operate with minimal supervision, while higher-risk decisions involving enteral or parenteral nutrition would continue to require direct clinician authorization. The article also highlights several major barriers that must be addressed before widespread clinical implementation becomes possible. These include AI hallucination risk, regulatory uncertainty, privacy concerns involving integrated patient data, and the potential for algorithmic bias when systems are trained predominantly on Western dietary and clinical datasets. The authors further note that no randomized controlled trials have yet evaluated AI-driven nutritional interventions against major oncologic outcomes such as survival or treatment completion. Overall, the editorial presents agentic AI as a potentially important next step in supportive cancer care. By integrating nutritional assessment, personalized dietary planning, and longitudinal patient monitoring into coordinated AI-driven systems, these technologies may help close longstanding gaps in oncology nutrition services while supporting more individualized and responsive patient care.

    Rare Dual-Mutation GIST Responds to Targeted Therapy, Challenging Established Tumor Biology

    BUFFALO, NY – May 6, 2026 – A new #casereport was #published in Volume 17 of Oncotarget on May 4, 2026, titled “Small bowel GIST harboring concurrent KIT exon 9 duplication and SDHC mutation: A case report.” The study was led by first author Cameron B. Speyer from the UCLA David Geffen School of Medicine, and corresponding author Joseph G. Crompton, who holds appointments at both the UCLA David Geffen School of Medicine and the Jonsson Comprehensive Cancer Center. In this report, the authors describe a rare and clinically informative case of a small bowel gastrointestinal stromal tumor (GIST) harboring two genetic alterations that are typically considered mutually exclusive. GISTs are most commonly driven by activating mutations in the KIT or PDGFRA genes, which confer sensitivity to targeted therapies such as imatinib. In contrast, tumors associated with succinate dehydrogenase (SDH) deficiency represent a distinct subgroup that is generally resistant to these treatments. The patient, a 68-year-old man, presented with progressive abdominal pain, bloating, and constipation. Imaging studies revealed a large heterogeneous mass in the lower abdomen measuring up to 18 cm. A biopsy confirmed a spindle cell neoplasm consistent with GIST, with immunohistochemical staining positive for CD117 and DOG1. Genomic analysis identified both a KIT exon 9 duplication (A502_Y503) and a germline SDHC mutation (p.R50C)—a highly unusual combination. Despite the presence of the SDHC mutation, which is typically associated with resistance to therapy, the patient demonstrated a strong response to high-dose imatinib. After six months of neoadjuvant treatment, imaging showed a marked reduction in tumor size and metabolic activity, enabling successful surgical resection. “This case suggests that oncogenic KIT signaling may remain the dominant driver of GIST behavior despite the presence of a germline SDHC mutation and highlights the importance of integrated molecular interpretation in GIST management.” Pathologic examination of the resected tumor revealed significant treatment response, including extensive necrosis and reduced tumor viability. Notably, immunohistochemistry demonstrated retained SDHB expression, indicating preserved SDH complex function despite the identified germline mutation. The case highlights an important clinical insight: not all detected genetic alterations contribute equally to tumor behavior. While SDH-deficient GISTs are typically resistant to imatinib, this tumor behaved in a manner consistent with KIT-driven disease, underscoring the importance of interpreting molecular findings within their clinical and pathological context. Overall, this report emphasizes the need for integrated molecular analysis in cancer diagnosis and treatment. As next-generation sequencing becomes more widely used, clinicians may encounter tumors with multiple coexisting mutations. Determining the dominant oncogenic driver is essential for selecting the most effective therapy and improving patient outcomes.

    Mapping the Hidden Structure of Glioma Research: What Are We Missing?

    Glioma research has evolved rapidly over the past decade, driven by breakthroughs in molecular biology, imaging technologies, and computational tools. Today, clinicians can classify tumors with far greater precision than ever before, using genetic mutations, epigenetic markers, and advanced diagnostic frameworks. Yet, despite this progress, an important question remains: are we truly capturing the full picture of what shapes patient outcomes? Traditionally, glioma classification has focused on what can be measured in the tumor itself—its histology, molecular profile, and biological behavior. While these factors are undeniably critical, they may not fully explain why patients with similar tumors can experience very different clinical trajectories. Increasingly, researchers are beginning to recognize that broader influences—particularly social and environmental factors—may also play a role. Understanding how these different layers of information connect is becoming an important challenge in neuro-oncology. A review was published in Volume 17 of Oncotarget on March 31, 2026, titled “Bibliometric mapping of glioma classification research through main path, key route, and K-core analyses.” The study was led by first and corresponding author Kayode Ahmed from The University of Texas MD Anderson Cancer Center, in collaboration with Juan E. Núñez-Ríos from Universidad Panamericana.

    Targeted Therapies Drive Long-Term Decline in Multiple Myeloma Mortality in the U.S.

    BUFFALO, NY – April 29, 2026 – A new #research paper was #published in Volume 17 of Oncotarget on April 28, 2026, titled “Targeted therapeutics and U.S. population-level mortality trends in multiple myeloma: A SEER-based analysis from 1975 to 2023.” The study was led by first and corresponding author Navkirat Kahlon from the Mass General Cancer Center at Wentworth-Douglass Hospital, in collaboration with researchers from multiple U.S. institutions. In this study, the researchers examined how mortality trends in multiple myeloma have changed in the United States over nearly five decades, using population-level data from the SEER database. Multiple myeloma, a cancer of plasma cells, has historically been associated with poor survival outcomes, but treatment options have evolved dramatically over time. The analysis revealed a clear shift in mortality trends that closely parallels major therapeutic advances. Between 1975 and the mid-1990s, mortality rates steadily increased, reflecting the limited effectiveness of early treatments such as alkylating agents and corticosteroids. A turning point emerged in the 1990s with the introduction of autologous stem cell transplantation, which marked the first meaningful improvement in survival outcomes. Over the following years, the development of targeted therapies—including immunomodulatory drugs and proteasome inhibitors—was associated with a more pronounced decline in mortality. These treatments introduced new mechanisms of action, such as immune modulation and enhanced cancer cell apoptosis, significantly improving disease control. More recent years have seen further progress with the introduction of monoclonal antibodies, maintenance therapies, and combination treatment strategies. Notably, the steepest decline in mortality occurred between 2021 and 2023, coinciding with the clinical adoption of advanced immunotherapies such as CAR T-cell therapies and bispecific antibodies. These treatments have shown the ability to induce deep and durable responses, even in heavily pretreated patients. “Our findings highlight the real-world impact of targeted therapies on population-level outcomes and underscore the urgent need for care models that ensure accessibility, affordability, and long-term sustainability in the era of precision oncology.” Importantly, while these therapeutic advances have improved survival, they have also introduced new challenges. Many patients now require long-term treatment, which can be associated with cumulative toxicities and a significant financial burden. In addition, access to these therapies remains uneven, influenced by geographic, socioeconomic, and healthcare system factors. Overall, this study provides a comprehensive, real-world view of how advances in cancer treatment have translated into measurable improvements in survival at the population level. At the same time, it highlights the need to ensure that these benefits are both sustainable and accessible to all patients as the field continues to evolve.

    SCD1 Inhibition Strategy Shows Potent Synergy with Regorafenib and Metformin in Tumor Cell Killing

    Cancer has long been understood through a variety of biological frameworks, including genetic mutations, dysregulated signaling pathways, and uncontrolled cell proliferation. Yet, these models often capture the visible consequences of disease rather than the deeper metabolic dependencies that sustain tumor survival. Despite major advances in targeted therapies, a central challenge remains: what underlying mechanisms make cancer cells vulnerable to treatment, and how can these vulnerabilities be exploited more effectively? Increasing attention has shifted toward cellular metabolism—particularly lipid regulation and energy-sensing pathways such as AMPK—as critical determinants of tumor behavior. Scientists are now taking a closer look at how metabolism works together with stress responses like autophagy—and how this connection could be used to develop better cancer treatments. A new research paper was published in Volume 17 of Oncotarget, titled “The SCD1 inhibitor aramchol interacts with regorafenib and metformin to kill tumor cells.” The study was led by first author Michael R. Booth and corresponding author Paul Dent from Virginia Commonwealth University, in collaboration with Laurence Booth and Jane L. Roberts from Virginia Commonwealth University and John M. Kirkwood from the University of Pittsburgh Cancer Institute.

    Epigenetic Dysregulation of PDX1 Drives Prostate Cancer Progression

    BUFFALO, NY – April 15, 2026 – A new #research paper was #published in Volume 17 of Oncotarget on March 31, 2026, titled “Epigenetic dysregulation and biological function of PDX1 in prostate cancer.” The study was led by first author Tayo A. Adeyika and corresponding author Bernard Kwabi-Addo from Howard University, Washington, DC. The team explored the role of the pancreatic and duodenal homeobox 1 (PDX1) gene in prostate cancer, with a focus on its epigenetic regulation and biological function. Their analysis identified PDX1 as differentially hypermethylated in prostate cancer tissues compared to normal prostate samples, alongside a paradoxical increase in protein expression in tumor tissues. Experiments in prostate cancer cell lines showed that PDX1 overexpression significantly enhanced cell proliferation and migration, while knockdown of PDX1 suppressed these tumor-associated behaviors. These findings point to a clear role for PDX1 in promoting aggressive cancer phenotypes. The work further shows that PDX1 regulates key metabolic, inflammatory, and epithelial–mesenchymal transition (EMT) pathways, including genes such as INSR, IGF1R, TWIST1, and SNAI1. Notably, these effects were more pronounced under high-glucose conditions, suggesting a link between metabolic state and prostate cancer progression. “Overall, our findings suggest that PDX1 plays a tumor-promoting role in human PCa cells by influencing expression of metabolites in insulin, inflammatory, and epithelial-mesenchymal transition (EMT) signaling pathways.” The authors conclude that PDX1 may represent a potential therapeutic target, particularly in the context of metabolic disorders such as obesity and diabetes, which are known to influence prostate cancer risk and progression. Their findings provide new insight into the interplay between epigenetics, metabolism, and tumor biology in prostate cancer.

    Cancer Care in Conflict Zones Remains Critically Neglected

    BUFFALO, NY – April 13, 2026 – A new #review was #published in Volume 17 of Oncotarget on March 31, 2026, titled “Cancer without borders: Policy frameworks for oncology care in humanitarian and conflict settings.” The study—led by corresponding author Pragnesh Parmar, along with Gunvanti Rathod from AIIMS Bibinagar, Telangana, India—brings together evidence from peer-reviewed studies, global health reports, and case examples from regions such as Gaza, Sudan, and Ukraine to examine the structural, ethical, and policy barriers limiting access to cancer care in humanitarian settings. Their findings show that oncology services are often excluded from emergency health priorities, resulting in delayed diagnosis, treatment interruptions, and reduced access to palliative care. The review further highlights that disrupted infrastructure, legal constraints, and fragmented policies disproportionately impact vulnerable populations—including women, children, and the elderly—who often present with advanced disease stages due to delays in care. “Addressing cancer in humanitarian contexts is not merely a technical challenge but a moral imperative.” The authors conclude that integrating oncology into humanitarian response frameworks is essential to ensure equitable access to care and improve outcomes for displaced populations. They emphasize the need for coordinated global strategies, including cross-border care models, tele-oncology, and policy reform, to address this critical gap in global health systems.

    Oncotarget Editorial Highlights Advances in Scientific Integrity and Publishing Transparency

    BUFFALO, NY – April 10, 2026 – A new #editorial perspective was #published in Volume 17 of Oncotarget on April 8, 2026, titled “Oncotarget: Past, Present and Future: Trends in the publishing industry.” Authored by the Scientific Integrity Office at Oncotarget, the editorial comprehensively analyzes the journal’s evolving approach to scientific integrity. It addresses historical challenges in scholarly publishing and discusses the necessity of modern image forensics tools to meet the most rigorous standards of scientific integrity. The Scientific Integrity Office describes how advances in digital technologies—particularly image forensics tools such as ImageTwin and analytical platforms like Argos—have transformed the ability to detect problematic data and analyze the quality of published research. The editorial emphasizes that the lack of adequate image tools in the “pre-tools” era limited journals’ ability to detect image-related issues, underscoring the importance of recent technological advancements. It also highlights that Argos provides a good opportunity to obtain a more objective picture across different journals in both the pre- and post-tools era. Looking forward, Oncotarget advocates indexes for broader adoption of independent analytical and AI-based tools in journal evaluation. In the public interest, it also encourages open discussion of how indexes select, deselect, and reevaluate journals.
