The 2025 American Society of Clinical Oncology (ASCO) Annual Meeting, a premier event in cancer research, showcased groundbreaking advancements in cancer treatment and detection. The discussions emphasized a future of more precise interventions, earlier diagnoses, and novel therapeutic approaches, with several studies marking significant milestones.
Exercise: A Prescribed “Drug” in Cancer Care: A particularly impactful finding presented at ASCO 2025 underscored the profound therapeutic role of exercise. A randomized Phase III trial led by Christopher Booth, MD, FRCPC, of Queen’s University in Kingston, Canada, revealed that a structured exercise program for survivors of stage III and high-risk stage II colon cancer significantly reduced the risk of cancer recurrence and improved overall survival. This landmark study, detailed in publications like The ASCO Post and ecancer, suggests that health systems should consider integrating such exercise programs as a standard component of post-treatment care.
Advancing Precision Medicine with Next-Generation SERDs: The conference reaffirmed the crucial shift towards highly personalized cancer care. Among the standout presentations was the Phase III SERENA-6 clinical trial (Abstract LBA4), funded by AstraZeneca, which investigated Camizestrant, a next-generation selective estrogen receptor degrader (SERD). Results showed significant progression-free survival benefits in patients with ER+/HER2- advanced breast cancer, especially those with ESR1 mutations. Experts like Eleonora Teplinsky, MD, Head of Breast and Gynecologic Medical Oncology at Valley-Mount Sinai Comprehensive Cancer Care, and Nick Turner from the Institute of Cancer Research and The Royal Marsden NHS Foundation Trust, highlighted its potential to redefine first-line treatment strategies by allowing early intervention upon detection of resistance mutations.
Immunotherapy Breakthroughs in Solid Tumors: Immunotherapies continue to expand their reach, with exciting new data on their application in challenging solid tumors. A landmark Phase II trial, CT041-ST-01 (NCT04581473), presented as Abstract 4003, showcased an autologous Claudin18.2-specific CAR T-cell therapy (Satri-cel). Led by researchers including Changsong Qi and colleagues in China, this study demonstrated significant improvements in progression-free survival and overall survival for previously treated patients with advanced gastric or gastroesophageal junction cancer, marking the first confirmatory randomized controlled trial of CAR T-therapy in solid tumors.
Promising New Drug Combinations Redefine Treatment Paradigms: Several studies introduced compelling results for novel combination therapies:
- For PIK3CA-mutated, HR-positive, HER2-negative advanced breast cancer, the Phase 3 INAVO120 trial presented final overall survival data. Led by Nicholas C. Turner, MD, PhD, of Royal Marsden Hospital, London, United Kingdom, this study demonstrated that adding inavolisib to palbociclib and fulvestrant significantly extended survival and delayed the need for chemotherapy, establishing a potential new standard of care.
- In BRAF V600E-mutant metastatic colorectal cancer, the Phase 3 BREAKWATER study (NCT04607421) showed unprecedented benefits. Presented by Elena Élez, a Medical Oncologist at Vall d’Hebron University Hospital, and with contributions from co-principal investigators Josep Tabernero and Scott Kopetz, the trial demonstrated that a first-line combination of encorafenib, cetuximab, and mFOLFOX6 chemotherapy significantly improved both progression-free and overall survival, signaling a radical shift in prognosis for this patient population.
Advancing Early Cancer Detection: The meeting also brought encouraging news in the realm of early cancer detection. Harbinger Health showcased the performance of its blood-based multi-cancer early detection (MCED) test, which utilizes circulating tumor DNA (ctDNA) methylation patterns. The data, primarily from the Cancer ORigin Epigenetics-Harbinger Health (CORE-HH) trial, conducted in collaboration with Sarah Cannon Research Institute, underscored the test’s promise in identifying various high-incidence cancers, particularly in at-risk populations.
These collective innovations presented at ASCO 2025 underscore a dynamic period in oncology, moving towards more effective, tailored, and earlier interventions that promise to reshape the future of cancer care globally.
