This issue marks the end of an era for Clinical & Experimental Metastasis with the retirement of Professor Sue Eccles from the position of Editor-in-Chief (Europe). Sue was a founding editor of the journal, launched in 1983 and she has served the journal admirably in this capacity for 32 years. Sue is Head of Tumour Biology and Metastasis Research at The Institute of Cancer Research in London, UK. She is well recognized for her research developing and testing compounds emerging from her Institute’s drug discovery program in preclinical models of progressive disease and has received numerous awards for her research over the years.

Clinical & Experimental Metastasis, the official journal of the Metastasis Research Society was launched a year before the first official meeting of this Society organized by Sue in London, along with the other founding editors of the journal, Professors Kurt Hellman, Garth Nicholson and Luka Milas. Kurt Hellman retired from editorship in 1985 and the editors were later joined by the current Editor-in-Chief (Asia), Professor Tatsuro Irimura. Following Garth Nicholson’s retirement in 2000, Professor Danny Welch joined as Editor-in-Chief (USA), handing over the reins to Professor Robin Anderson in 2010. Throughout this time, Sue has guided the journal to the strong position that it holds today as the leading journal in the metastasis research field. Personally I have consulted her on many occasions on issues related to the journal, authors or reviewers and have always received a sensible and measured response.

On behalf of the Metastasis Research Society and the other editors, I would like to take this opportunity to thank Sue for the time, effort and enthusiasm she has put into the development of the journal over more than three decades.

I am pleased to welcome Professor Jonathan Sleeman from the Universitätsmedizin Mannheim, University of Heidelberg, Germany, who has been appointed to take over as Editor-in-Chief (Europe) commencing with this issue.
