In a remarkable stride toward advancing treatments for life-threatening diseases, the City of Hope research community has unveiled a series of influential scientific findings that have the potential to reshape therapeutic strategies across oncology and immunology. Anchored in cutting-edge research, these discoveries span diverse areas from prostate and pancreatic cancers to immune system restoration and targeted drug design, illustrating the institution’s commitment to transforming patient care through innovation.
One of the pivotal studies, led by Dr. Abhishek Tripathi, reveals that incorporating docetaxel chemotherapy alongside conventional hormone therapy significantly enhances long-term survival rates for men battling advanced prostate cancer. This investigation, published in the Annals of Oncology, elucidates how monitoring prostate-specific antigen (PSA) levels after six months of treatment can effectively predict patient outcomes. Such insights empower clinicians to tailor treatment regimens by escalating or de-escalating therapy intensity, potentially minimizing toxicity without compromising efficacy.
Further illuminating immune recovery mechanisms, researchers including Drs. Andri Lemarquis and Marcel van den Brink have identified the role of interleukin-18 (IL-18) in post-injury thymic function. Their findings indicate that IL-18 signaling stimulates natural killer (NK) cells to inhibit thymic regeneration, thereby delaying immune reconstitution after acute insults such as bone marrow transplantation. Intriguingly, their Nature Immunology publication describes how blockade of IL-18 or NK cell activation facilitates faster thymic repair, suggesting novel therapeutic avenues to bolster immune resilience and enhance infection resistance in immunocompromised patients.
Meanwhile, breakthroughs in pancreatic cancer research have centered on the protein STN1, a facilitator for DNA repair that enables tumor cell survival under genotoxic stress. Professor Terence Williams and his team demonstrated in Nucleic Acids Research that elevated STN1 levels, driven by the prevalent oncogene KRAS, confer radioresistance to pancreatic cancer cells. Disruption of STN1 sensitizes these cells to radiation therapy independently of their traditional complex partners, marking STN1 as a promising molecular target for improving therapeutic responses in KRAS-mutated malignancies.
Advances in drug discovery are also highlighted by the innovative work of Professor Nagarajan Vaidehi and assistant research professor Ning Ma, who introduced the concept of “protein frustration” as a predictive metric for the efficacy of PROTACs—bifunctional molecules designed to degrade pathologic proteins. Their investigation, detailed in Nature Communications, reveals that quantifying intramolecular tension within protein complexes can guide the rational design of these targeted degraders, expediting the development of precision medicines for diseases characterized by aberrant protein activity.
On the front of genomic stability, Professors Li Zheng and Binghui Shen elucidated novel cellular mechanisms that resolve complex DNA secondary structures known as G-quadruplexes (G4s). Their publication in Nature Communications highlights how the DNA helicase/nuclease DNA2 and the mismatch repair protein MSH2 cooperate to dismantle G4s formed at telomeric ends. This intricate maintenance is essential for preventing chromosomal instability, a hallmark of oncogenesis. Additionally, environmental mutagens exacerbating G4 formation underscore the pressing need for therapeutic strategies to safeguard genome integrity in cancer prevention and treatment.
In the realm of precision oncology, a City of Hope study spearheaded by Drs. Joanne Mortimer and Stephen Gruber advocates for universal BRCA1/2 genetic testing in all breast cancer patients, irrespective of age or ethnicity. Published in JAMA Network Open, this research uncovers a disproportionate prevalence of BRCA1 mutations in Hispanic women and a notable incidence of pathogenic variants in patients over 60. By challenging traditional risk-based screening paradigms, these findings champion broader molecular diagnostics to enhance individualized patient management and improve outcomes.
Confirming the real-world performance of CDK4/6 inhibitors, Professor Hope Rugo’s comprehensive study involving over 9,000 patients affirms comparable efficacy among palbociclib, ribociclib, and abemaciclib when paired with hormone therapy for hormone receptor-positive advanced breast cancer. Documented in ESMO Open, these results substantiate flexible therapeutic choices for clinicians and patients, reinforcing that treatment selection can be guided by factors beyond efficacy, including tolerability and patient preference.
Addressing supportive care, the work of Professor William Dale introduces GAIN-S, a telehealth-based program delivering geriatric assessment and supportive interventions for older adults with advanced cancer. Published in Cancer, the program’s impact extends beyond symptom management, enhancing emotional preparedness, spiritual well-being, and functional capacity, thereby enriching the quality of life even amid incurable diagnoses. This telehealth approach signals a promising model to extend specialized supportive care to resource-limited settings.
Harnessing the potential of artificial intelligence, a team led by Drs. Kun-Han (Tom) Lu and Sina Mehdinia has developed an advanced AI model trained on an expansive dataset of oncology clinical notes. This bespoke system employs deep learning to rapidly extract clinically relevant information from electronic health records, forming the basis for HopeLLM—a suite of generative AI tools integrated within City of Hope to streamline clinical decision-making and accelerate research data retrieval. Though still preclinical, as reported in JCO Clinical Cancer Informatics, this technology exemplifies the transformative promise of AI in personalized cancer care.
Alongside these scientific triumphs, City of Hope celebrated significant professional recognitions. Dr. Ravi Salgia was honored as a 2025 My SoCal Hospital Hero for his exceptional dedication and leadership in medical oncology, while Dr. John Carpten received the Cancer Health Equity Award from the Association of American Cancer Institutes for his pioneering work addressing disparities in cancer outcomes. These accolades underscore the institution’s unwavering commitment to scientific excellence and equitable patient care.
City of Hope’s integrated ecosystem, encompassing its National Cancer Institute-designated comprehensive cancer center, the Beckman Research Institute, and affiliated entities such as the Translational Genomics Research Institute, continues to serve as a beacon of innovation. Through its multidisciplinary approach bridging fundamental science and clinical application, City of Hope persistently pioneers breakthroughs that bring hope and healing to patients confronting complex diseases.
