This note is from my newsfeed: I have no comments to make, but it seems important.
Zion Levi’s melanoma went into remission thanks to a powerful immunotherapy drug called nivolumab. Then he donated his faeces — and the microbes inside — to help others who had failed to respond to the treatment or whose cancers had become resistant to it. It was a small trial — it involved only 26 people — but one in three of them benefited from the faecal microbial transfer (FMT). Today, at least 30 FMT trials are under way around the world. They hint at a new era of ‘ecological oncology’ and aim to uncover how the gut microbiome influences the progression of distant tumours, the effectiveness of treatments and the organisms that live in tumours themselves.
