Retraction of medical papers reviewed

An international medical journal's retraction of 107 papers by Chinese medical researchers has severely harmed the reputation and integrity of the country's scientific community and revealed a flawed oversight system, according to the Ministry of Science and Technology.

In late April, Tumor Biology, a journal published by Germany-based Springer Nature, announced it had retracted the papers after an investigation showed the peer review process had been compromised.

Nearly all of the 524 authors connected with the papers are clinical cancer doctors at key public hospitals.
