Among the most compelling studies featured is a large-scale retrospective analysis evaluating the safety of rechallenging metastatic breast cancer patients with trastuzumab-deruxtecan (T-DXd) following episodes of low-grade interstitial lung disease (ILD). T-DXd, an antibody-drug conjugate approved for HER2-positive and HER2-low breast cancers, entails a rare but significant risk of ILD. This study of 712 patients provides robust real-world evidence that carefully managed rechallenge post-ILD resolution is feasible and can confer substantial clinical benefit. Importantly, steroid administration accelerated radiographic ILD improvement, underscoring timely immunomodulatory interventions to mitigate pulmonary toxicity.

City of Hope researchers meticulously gathered detailed data including patient demographics, T-DXd dosing schedules, steroid use, imaging results, and outcomes from rechallenge protocols. Approximately 9% of treated patients developed ILD, with 47 individuals undergoing drug rechallenge primarily after grade 1 (asymptomatic) ILD. Notably, the recurrence of ILD was predominantly low-grade, with no fatal-grade 5 events recorded. Following rechallenge, patients maintained therapy for a median duration exceeding seven months, suggesting durable benefit despite initial pulmonary complications. These findings provide a critical evidence base to inform clinical decision-making in managing T-DXd-associated ILD.

Shifting focus to genitourinary oncology, City of Hope investigators revealed novel insights into the genomic evolution of renal cell carcinoma (RCC) and its recurrence patterns. Despite curative-intent nephrectomy, about one-fifth of RCC patients experience relapse, posing a clinical challenge. Through precision medicine approaches, the team analyzed pretreatment tumor tissue from 754 patients enrolled in the IMmotion010 Phase 3 trial, which assessed the adjuvant efficacy of the monoclonal antibody atezolizumab. While the trial overall did not demonstrate prevention of disease recurrence, genomic profiling delineated molecular subgroups, particularly those with high KIM-1 biomarker expression and enriched tumor effector (Teff) immune cells, who exhibited prolonged disease-free survival with atezolizumab.

This integrative genomic and transcriptomic profiling illuminates the heterogeneity underlying RCC recurrence and response to immunotherapy. Cluster 6 tumors, characterized by stromal and proliferative signatures, represented a distinct subset deriving benefit from adjuvant checkpoint inhibition. Furthermore, longitudinal analysis through whole-transcriptome sequencing at baseline and recurrence revealed dynamic genomic shifts, offering mechanistic explanations for disease progression. These discoveries pave the way for refined biomarker-driven patient selection, enabling personalized immunotherapeutic strategies that may effectively delay or prevent relapse.

In colorectal cancer, a notoriously immunoresistant malignancy due to prevalent microsatellite stability (MSS), City of Hope’s Phase 2 trial of dual checkpoint inhibition showcases encouraging preliminary results. The combination of Vilastobart (XTX101), an investigational immune checkpoint modulator, with atezolizumab demonstrated tumor shrinkage in patients with advanced MSS colorectal cancer—a group traditionally unresponsive to immunotherapy. Approximately 27% of patients without hepatic metastases achieved partial responses, accompanied by notable reductions in circulating tumor DNA levels, bolstering evidence of anti-tumor activity.

This clinical evaluation, involving heavily pretreated patients, advances the frontier of immuno-oncology by overcoming established resistance mechanisms. The favorable safety profile, marked by low occurrences of severe immune complications and minimal treatment discontinuations, further substantiates the regimen’s potential. Vilastobart’s development by Xilio Therapeutics, co-founded by City of Hope scientist Dr. John Williams, exemplifies translational innovation bridging scientific discovery to clinical application. These data may herald a new era of combinatorial immunotherapies tailored for colorectal cancer subsets.

Turning attention to prostate cancer, a comprehensive observational study led by Dr. Alan H. Bryce leveraged extensive real-world data comprising over 68 million U.S. Medicare and Medicaid beneficiaries. This investigation scrutinized cardiovascular outcomes among metastatic castration-resistant prostate cancer (mCRPC) patients treated with either abiraterone acetate or enzalutamide, two primary androgen-targeting agents. Findings reaffirmed clinical trial signals that abiraterone acetate is associated with a significantly elevated risk of cardiovascular events—including myocardial infarction, stroke, and arrhythmias—compared to enzalutamide, especially in patients without prior chemotherapy.

Strikingly, the risk of all-cause mortality was also heightened in the abiraterone cohort regardless of cardiovascular disease history. These real-world insights emphasize the need for vigilant cardiovascular risk stratification and therapeutic selection in this vulnerable population. By integrating large-scale epidemiological data, the study transcends the limitations of controlled clinical trial environments, offering pragmatic guidance for optimizing treatment algorithms that balance oncologic efficacy with cardiovascular safety.

Collectively, City of Hope’s multifaceted research portfolio presented at ASCO 2025 underscores the institution’s leadership in pioneering personalized oncology solutions rooted in rigorous science and clinical pragmatism. Their work exemplifies how combining molecular diagnostics, real-world evidence, and innovative trial designs accelerates the translation of cutting-edge therapies to patient benefit. As the oncology community converges in Chicago and online, these findings promise to reshape therapeutic landscapes, inspire new collaborations, and invigorate efforts to enhance survival and quality of life for cancer patients worldwide.

City of Hope’s ongoing commitment encompasses not only breakthrough treatment modalities but also the integration of supportive care interventions aimed at reducing cancer risk and improving survivorship outcomes. By embracing a holistic research agenda that spans breast, kidney, colorectal, and prostate cancers, the institution advances the broader mission of transforming hope into reality through science-driven innovation. The upcoming ASCO presentations will undoubtedly catalyze further advancements and highlight the critical role of multidisciplinary expertise in confronting cancer’s complexities.
