SCIENCE MARCHES ON: Harvard Teaching Hospital Seeks Retraction of Six Papers by Top Researchers: Dana-Farber Cancer Institute is reviewing more than 50 papers, including work of the hospital’s CEO.

The Dana-Farber Cancer Institute, a Harvard Medical School affiliate, is seeking to retract six studies and correct 31 other papers as part of a probe involving four of its senior cancer researchers and administrators.

More than 50 papers, including four co-authored by Chief Executive and President Dr. Laurie Glimcher, are part of a continuing review, according to Dr. Barrett Rollins, the cancer institute’s research-integrity officer. Some requests for retractions and corrections have already been sent to journals, he said. Others are being prepared. The institute has yet to determine whether misconduct occurred.

Also under investigation are papers co-authored by Chief Operating Officer Dr. William Hahn; Director of the Clinical Investigator Research Program Dr. Irene Ghobrial; and Dr. Kenneth Anderson, program director of the Jerome Lipper Multiple Myeloma Center.

All four researchers have faculty appointments at Harvard Medical School, making it the latest tranche of misconduct allegations leveled at Harvard researchers. Claudine Gay resigned as Harvard University president early this year, facing allegations of plagiarism. Last year, Harvard Business School placed Prof. Francesca Gino on administrative leave after accusations that her work contained falsified data.

Glimcher and the other researchers didn’t respond to requests for comment.

Dana-Farber’s disclosure about its probe arrived after a data sleuth pointed to irregularities in the researchers’ papers.

In early January, molecular biologist Sholto David published a blog post describing what he said were signs of image manipulation in papers by the Dana-Farber researchers. David contacted Dana-Farber and Harvard Medical School with his concerns, submitting a list of papers he said contained problems.

The most serious, he said, had to do with images of experimental results that had signs of copy-and-pasting by software such as Adobe Photoshop. “Those are pixel-perfect matches for the same area, but it’s supposed to be a different sample,” he said.

It’s a bad year for Harvard’s brand.
