Do you believe in meta-analysis?

Niall Boyce welcomes Professor Stuart Pocock, author of two Lancet papers, published 35 years apart: 1991's "Can meta-analyses be trusted?" and 2026's "What makes a meta-analysis believable?" They discuss what makes a trustworthy meta, and how the smart clinician should use the totality of evidence to inform clinical care.

In this episode of The Lancet In Conversation With, editors Niall Boyce and Bea Gómez Pérez-Nievas are joined by three leading researchers to discuss highlights from The Lancet's special issue on neurology. The conversation covers three landmark studies: the PADOVA trial of prasinezumab in early-stage Parkinson's disease, the ORATORIO-HAND study extending ocrelizumab treatment to wheelchair-using patients with progressivemultiple sclerosis, and the HEAD study comparing tau PET tracers in Alzheimer's disease — each representing a significant step forward in the field. The guests also reflect on the broader forces reshaping neurology: the push toward earlier, biomarker-guided intervention, cross-specialty learning between the multiple sclerosis, Alzheimer's, and Parkinson's fields, and emerging platforms such as CAR T-cell therapies and blood-based biomarkers. From the transformative success of spinal muscular atrophy treatment to the prospect of an EBV vaccine preventing MS, the discussion strikes a note of cautious optimism about a specialty that is entering a new therapeutic era.

In Conversation with The Lancet returns with Dr Susannah Stanway, honorary consultant medical oncologist at the Royal Marsden and honorary clinical senior lecturer in Education at the Institute of Cancer Research, reflecting on London Global Cancer Week 2025. This episode goes beyond event highlights to discuss the need for a global oncology agenda rooted in equity, evidence-based care, and value across care settings. Topics span from geriatric oncology to cardio-oncology, nursing workforce resilience, cancer care in conflict zones, and sustainable health financing, showing how multi-stakeholder collaboration can drive policy and practical improvements, especially in low- and middle-income countries. Listeners will take away practical steps for action: integrating geriatric assessment and baseline cardiovascular risk checks, strengthening cancer registries and national audits, and pursuing domestic funding for universal health coverage. The discussion highlights the urgency of addressing cancer globally including context specific solutions sensitive to local settings and emphasises prevention, early diagnosis, and accessible treatment as core priorities.

Ultra-processed foods are on the rise. Despite the emphasis placed on individual responsibility, our deteriorating diets are primarily the result of the sophisticated political tactics of a powerful global ultra-processed food industry. Addressing this urgent threat demands a coordinated response from the global public health community. So argues a 3-paper Series published in The Lancet that examines the evidence, proposes policies to halt and reverse the rise in ultra-processed foods, and illuminates the fundamental political and economic drivers at play. Professor Carlos Monterio, Professor Camila Corvalán, and Professor Phil Baker join host Callam Davidson to discuss this powerful and timely Series.
