A Columbia surgeon’s study has been withdrawn. He continued to publish erroneous data.

Stomach cancer study was riddled with suspect data. Identical constellations of cells would represent distinct experiments on entirely different biological lineages. Photos of mice with tumors, used to show that a drug reduced cancer growth, had been featured in two previous papers describing other treatments.

The problems with the study were serious enough. that its editor, after finding that the article violated ethical guidelines, officially withdrew it a few months after its publication in 2021.
