The Education of a Value InvestorAuthor: Guy Spier
I'm a work in progress. This podcast documents my ongoing quest for wealth, wisdom and enlightenment. The episodes are of variable length: When I find an interesting person to talk to - who is willing to have the conversation recorded, I put it up. But I have also found that it is useful to record my own thoughts - in short snippets. Language: en Genres: Business, Investing, Management Contact email: Get it Feed URL: Get it iTunes ID: Get it |

My first clinical Trial: 5-ALA & Glioblastoma re-irradiation
Episode 59
Thursday, 23 April, 2026
For the first time, investor Guy Spier steps outside the world of finance to share a deeply personal conversation—with the doctors who treated him. Recorded at the University Hospital Münster, this discussion with neurosurgeon Dr. Michael Müther and radiation oncologist Dr. Niklas Pepper explores the frontiers of brain cancer treatment, focusing on glioblastoma and a groundbreaking clinical trial combining 5-ALA (Gliolan®) with radiotherapy. Topics covered: What glioblastoma is and why it’s so difficult to treat The Stupp protocol and why recurrence is common How 5-ALA fluorescence surgery helps surgeons “see” tumors The role and evolution of radiotherapy and re-irradiation A new approach: radiodynamic therapy (5-ALA + radiation) How clinical trials work (Phase I, dose escalation, safety focus) Why patient participation is critical to medical progress The conversation also explores the human side of medicine: Should patients deeply engage with their disease—or not? The role of mindset, movement, and psycho-oncology How doctors balance research, clinical care, and uncertainty This is a rare, candid look at how modern medicine advances—from lab to patient—and the people behind it.
