About Us

Dear friends of EHTG,
We have been quite silent in 2020 and apologize for this.

As you may know, the Mallorca Group was the European successor to the International Collaborative Group on Hereditary Non-Polypposis ColorectalCololorectal Cancer (ICG-HNPCC) which had been set up earlier, to identify the genes causing HNPCC.

InSiGHT was created by merger with international research groups that had identified other GI cancer predisposition genes and the European core members of ICG-HNPCC also decided to continue their European collaboration: in 2006 they met for this purpose in Mallorca and the Mallorca group was born.

In 2012 the Prospective Lynch Syndrome Database was established to examine the risk for cancer in carriers of pathogenic variants of the MMR genes and effects of interventions. The Mallorca group was formalized in 2016 with Gabriela Möslein as chair/trustee together with John Burn, Julian Sampson and Pål Møller as trustees and it was incorporated as the European Hereditary Tumour Group - EHTG.

It was established as an open forum and all interested individuals were free to join. While the primary focus was on inherited gastrointestinal tumours, the intention was to evolve and embrace other inherited cancer syndromes.

EHTG has defined its aims as:

  • To conduct collaborative studies
  • To establish guidelines
  • To set up databases to increase our understanding of hereditary tumour syndromes

We welcome everybody interested to get actively involved and join us in these efforts to improving our knowledge in the field of hereditary predisposition to cancer and to implement this knowledge for improved clinical care. This effort embraces all clinical disciplines!

An interactive working group format was tried and was well-received during the first meeting of the EHTG in Mallorca in 2016.

In 2017, we teamed up with InSiGHT at a wonderful meeting in Florence, Italy (Chairpersons Maurizio Genuardi and Luigi Ricciardello) and hosted a one day meeting on 5 July.

In 2018, we held the 3rd meeting of the European Hereditary Tumour group on Sunday 23 to Tuesday 25 September 2018 in Nice, France, with an additional joint EHTG/ESCP symposium at ESCP on Wednesday 26 September.

In 2019, we hosted the 4th meeting of the European Hereditary Tumour Group in Barcelona, Spain on Wednesday 17 – Saturday 19 October ahead of UEG Week that was also being hosted in the city.
