Landmark abstracts across localized and advanced prostate cancer presented at ASCO 2026 addressed treatment intensification, biomarker-driven therapy, radiotherapy modality comparisons, and novel radioligand strategies. In this piece we examine four studies that reflect important shifts in prostate cancer management, influencing both near-term treatment pathways and future: PROTEUS, TALAPRO-3, COMPPARE and ProstACT Global.

Several late-breaking gastrointestinal oncology studies presented at ASCO 2026 highlighted how treatment selection is continuing to evolve across colorectal, hepatobiliary, gastric, and esophageal cancers, with new data on ctDNA-guided adjuvant therapy, earlier integration of targeted agents, and intensified perioperative strategies. In this round-up, we have selected six of the most important late-breakers, and examine the latest data from CIRCULATE, BREAKWATER, EMERALD-3, Neo-CRAG, SCIENCE, and RC48-C027.

New ASCENT-04 data presented at ASCO 2026 suggest that first-line sacituzumab govitecan plus pembrolizumab may provide sustained clinical benefit beyond first progression in patients with previously untreated PD-L1-positive metastatic triple-negative breast cancer. The exploratory post-hoc analysis showed improved PFS2 versus chemotherapy plus pembrolizumab, despite high crossover to sacituzumab govitecan in the control arm.

Dr Rupert Bartsch (University of Vienna, Austria) highlighted six important studies across the breast cancer landscape presented at ASCO 2026. The studies below discuss interesting and strategic developments in genomic risk stratification in early disease, supportive care optimization, HER2-positive metastatic strategies and novel antibody–drug conjugates in triple-negative breast cancer.

At ASCO 2026 several neuro-oncology presentations focused less on introducing entirely new paradigms and more on defining where existing and emerging therapies may best fit. Across brain metastases and glioma, phase 3 data addressed longstanding practical questions around radiation delivery, chemotherapy duration, and local therapies, while updated targeted therapy data in IDH-mutant glioma continued to mature. In this piece, Dr Rimas Lukas highlights four main abstracts from ASCO 2026, discussing their take-aways and considering their potential relevance for clinical practice.

ASCO 2026 showed that thoracic oncology is moving beyond promising signals and increasingly closer to practice-changing evidence across multiple fields — from bispecific antibodies and ADC-based combinations to targeted therapy in both metastatic and peri-operative settings. In this piece, Dr Federico Monaca breaks down eight major abstracts from ASCO26, highlighting their take-aways and considering their potential relevance for clinical practice.

The five selected Plenary late-breaking abstracts at the ASCO 2026 Annual Meeting in Chicago showcased some of the meeting’s most practice-influencing data. Across prostate cancer, sarcoma, lung cancer and pancreatic cancer, these phase 3 studies demonstrated meaningful improvements in survival outcomes, highlighting the growing impact of perioperative intensification, precision oncology and novel targeted therapies in difficult-to-treat disease settings.

At the 7th SIOP Europe Annual Meeting, Anita Kienesberger (Chair, Childhood Cancer International Europe [CCI Europe]), discusses the evolving landscape of paediatric oncology advocacy. She shares insights on the critical importance of psychosocial support, the necessity of collaborative research and the ongoing challenge of health inequalities across Europe. As CCI Europe transitions into an independent legal entity, Anita Kienesberger highlights the organisation's strategic shift toward empowering survivors and standardising long-term care.

The 38th Annual Congress of the European Association of Nuclear Medicine (EANM) in Barcelona brought together over 9,400 participants, marking a major milestone. The meeting highlighted major advances in oncologic imaging and theranostics, with a strong emphasis on precision medicine and combination treatment strategies. Across plenary sessions, debates, and late-breaking discussions, the meeting underscored how nuclear medicine is increasingly central to cancer diagnosis, treatment selection, and therapeutic delivery.
