HRI has been made aware of an investigation into a study published by Frass et al.1 in The Oncologist journal in 2020.

Serious allegations have been made against the research team which are strongly refuted by those involved. It is essential that the authors are given a formal ‘right of reply’ to respond to the charges made against them – something they have been denied as yet. HRI will continue to monitor this ongoing situation closely.
