Had a conversation with someone outside of healthcare recently who was shocked by how long it takes to run clinical trials in the U.S (not to mention expensive). I tried to explain—it’s not just the science. It’s the infrastructure. Every site needs dozens of personnel, many of

📊 Are we overestimating success in ph3 oncology trials? 📉 Only 6% of ph3 oncology RCTs show improvement in both OS and QoL. Most “positive” trials rely on surrogate endpoints, often without adjusting QoL for baseline. We must refocus trials on what truly matters to patients.

Middle East and North African countries are underrepresented in oncology clinical trials, with higher participation in observational, late-phase, and industry-funded trials, and greater representation in countries with higher GDP. ja.ma/4jWY8nQ

Wide variation in TNT regimens for rectal cancer in Europe. Variation IMO good, as treatment should be tailored to tumor features & pt preferences – not one size fits all. Reassuring that on matched analyses, no OS difference b/w different regimens. jamanetwork.com/journals/jamao…

Novel cell therapies to treat solids cancers will be a huge challenge to EU health systems; cost, accessibility and clinical expertise will need to be carefully traded off. Here we describe a model to help policymakers do just that. sciencedirect.com/science/articl… ASCO AACR ESMO - Eur. Oncology

A final piece of advice from Holly Butcher - written the day before she passed away from cancer at just 27: “It’s a strange thing knowing you’re going to die young. At 26, I thought I had time… To fall in love. Start a family. Grow old. But cancer doesn’t care about plans.

“It’s a strange thing knowing you’re going to die young.

To fall in love.

Grow old.
