The surrogacy value of distant disease-free survival for overall survival has not been validated in neoadjuvant randomised controlled trials (RCTs) for early breast cancer. Here, we assess the trial-level surrogacy value of distant disease-free survival for overall survival.

The efficacy of resection in IDH-mutant grade 2 gliomas remain controversial since terminology for the extent of resection has been inconsistently applied across studies. We aimed to establish a standardised classification for the extent of resection and assess the association between supramaximal resection and survival across molecular subtypes.

Rectal surgery after total neoadjuvant therapy is a standard of care for proficient mismatch repair or microsatellite stable (pMMR/MSS) stage II-III rectal cancer. In patients who have clinical complete response, non-operative management (avoidance or delay of surgery and intensive surveillance) offers a patient-centred opportunity. However, its effect on metastatic recurrence remains uncertain. This study aimed to determine whether non-operative management compromises distant relapse-free survival in patients with clinical complete response after total neoadjuvant therapy.

Pembrolizumab (anti-PD-1 antibody) plus lenvatinib (multityrosine kinase inhibitor) showed high clinical activity in PEMMELA cohort 1 in patients with pleural mesothelioma pre-treated with platinum-based chemotherapy. This study (cohort 2) aimed to investigate the clinical activity of this combination in patients with pleural mesothelioma who progressed after first-line nivolumab plus ipilimumab.

Brain-infiltrating tumour cells from high-grade glioma remain shielded from drug treatments by the blood-brain barrier, leading to inevitable recurrence. Microbubble-enhanced transcranial focused ultrasound (MB-FUS) enables controlled blood-brain barrier opening (BBBO), permitting localised drug delivery. We aimed to assess safety and feasibility of MB-FUS plus standard-of-care chemotherapy for individuals with high-grade glioma.

The Lucerne Toolbox 3 initiative addresses the pressing need for evidence-based integration of digital health and artificial intelligence (AI) technologies in early breast cancer care. The multidisciplinary consortium identified and prioritised 15 crucial medical knowledge gaps across the patient journey, from diagnosis to treatment and survivorship, using a modified Delphi consensus process with 112 unique members from 27 countries and 16 medical societies, trial groups, and patient organisations. The knowledge gaps include AI-based mammography screening, personalised screening strategies, digital knowledge databases, AI-driven treatment optimisation, and digitally delivered monitoring and supportive care. The consortium developed 13 trial designs in the Population, Intervention, Comparison, and Outcome format to address these gaps, achieving consensus or majority vote in 98% of statements. The recommendations emphasise precision medicine, patient-centred care, and interdisciplinary collaboration to improve outcomes, efficiency, and equity in breast cancer care. By presenting a roadmap for actionable trials, Lucerne Toolbox 3 sets a foundation for advancing digital health in breast cancer care.

Patient-reported outcome measure (PROM) surveillance and collaborative care improve cancer symptom control. However, human resource requirements constrain their implementation and reach. Electronic health record (EHR) facilitation reduces resource needs and might allow population-level scaling. We aimed to assess the effect of EHR facilitation of PROM-directed collaborative care on clinical and health services outcomes.

Multimodality therapy, including surgery, radiotherapy, and systemic therapy, has significantly improved overall survival for patients with brain metastases. However, treatment-related neurocognitive sequelae remain a major challenge in survivorship. Although advances in radiotherapy delivery techniques have reduced toxicity, the potential interaction with chemotherapy, targeted therapy, and immunotherapy, and the consequent effect on neurocognitive outcomes is poorly characterised. We conducted a systematic review of clinical trials reporting neurocognitive endpoints in patients with brain metastases receiving radiotherapy with or without other concurrent systemic therapies. Neurocognitive outcomes were manually extracted from published reports. 39 studies from 1997 to 2024 involving 6617 patients met inclusion criteria (n=27 whole-brain radiotherapy; n=12 radiosurgery), including six studies evaluating combined-modality therapy. Baseline neurocognitive disability was frequently observed, and the majority of randomised trials evaluating advanced radiotherapy delivery techniques (hippocampal avoidance and radiosurgery) compared with whole-brain radiotherapy reported reduced cognitive decline and improved quality of life. There was no signal for increased toxicity with combined-modality therapy, including radiotherapy with concurrent systemic therapy, although evaluable trials were few in number. Given improvements in survival for patients with brain metastases, characterisation of long-term neurocognitive outcomes is growing in importance. There is an urgent need for targeted research to resolve evidence gaps around modality-specific neurocognitive toxicity and optimal sequencing of therapies. Systemic issues, such as integration of routine neuropsychological screening or assessment and incorporation of rehabilitation strategies into neuro-oncology care pathways, warrant evaluation. Exploration of emerging strategies, ranging from neuroprotectants to dose-sparing radiotherapy techniques, could further mitigate long-term adverse effects.

Standardising the implementation of patient-reported outcomes (PROs) in clinical trials is crucial for evaluating the benefits and risks of cancer treatments. The Setting International Standards in Analysing Patient-Reported Outcomes and Quality of Life Endpoints in Cancer Clinical Trials-Innovative Medicines Initiative (SISAQOL-IMI) has developed 146 consensus-based recommendations for designing, analysing, interpreting, and presenting PROs in cancer clinical trials. This initiative, undertaken from 2021 to 2025, involved experts, including statisticians, PRO measurement experts, clinicians, and patient representatives from 41 organisations representing regulatory agencies, academia, the pharmaceutical industry, health-technology assessment bodies, and patient advocates. SISAQOL-IMI provides guidance on the implementation of PROs in randomised controlled trials and single-arm trials, terminology, definitions and the selection of PRO score interpretation thresholds, and for visualising PRO results for different audiences. To facilitate the implementation of these standards, in addition to this Policy Review, four key outputs are available: an interactive table, a guidebook, plain language materials, and a glossary.

The phase 3 CARES-310 trial showed significant improvements in progression-free survival (primary analysis) and overall survival (interim analysis) with the anti-PD-1 antibody camrelizumab plus the oral vascular endothelial growth factor receptor 2 inhibitor rivoceranib versus sorafenib as first-line treatment for unresectable hepatocellular carcinoma. Here, we present the final analysis of overall survival, and updated data on progression-free survival, secondary efficacy endpoints, and safety.
