Irish Sarcoma Group

About ISG

The Irish Sarcoma Group is the association of specialist clinicians, nurses and supporting professionals who treat people with sarcoma on the island of Ireland.

The ISG was founded in 2014 and holds its annual meeting in November/December

The first patient-focused event was held in December 2015. This gave the general public, patients and their friends and family an opportunity to meet each other and the experts involved in managing this disease.

This website has been developed by Dr Charles Gillham co-founder of the Irish Sarcoma Group. Funding for this website was made available by the friends and family of the late Dara Byrne.

The aim of this website is to help inform the public about sarcoma. Health care professionals will also find some useful information here and guidelines for referral.

The aims of the Irish Sarcoma Group are:

  • To help develop and strengthen national sarcoma services
  • To raise awareness amongst the public and medical professionals about this rare group of diseases
  • To provide education, training and identification of best practice for all professionals treating people with sarcoma
  • To promote excellence in care and treatment of people with sarcoma through identification and sharing of best practice
  • To promote and support research and the development of more effective treatment and care

Professor O’Sullivan is a consultant paediatric pathologist working at CHI at Crumlin (formerly OLCHC), which houses the national paediatric oncology-haematology unit. Her specific interest is in paediatric solid tumours and, in the research setting, the genetics, epigenetics and biology of these tumours. Professor O’Sullivan’s group particularly focuses on sarcomas and paediatric renal tumours. They have characterised several novel chromosomal translocations and studied the biological impact these have on cell biology. The work has benefits in terms of diagnosis, prognosis, biological understanding and novel therapeutic development for these rare cancers, which are all too often neglected despite their aggressive behaviour.

Dr Heather McCarthy Clinical Oncology Belfast

Dr Heather McCarthyDr McCarty completed her clinical oncology training in Belfast and then spend 6 months with the paediatric and sarcoma team in Birmingham before a further 2 year clinical fellowship in Princess Margaret Hospital, Toronto. In 2010 she returned to the UK to take up consultant post in Belfast. Since then she has sought to develop the regional sarcoma service building on the established orthopaedic led practise with greater integration of plastic surgical and retroperitoneal surgical teams. Her involvement with the paediatric oncology service has helped in development of the regional teenage and young adult service. Much progress has been made but there’s still some way to go to ensure her goal is met that every patient with ‘query sarcoma’ has timely access to appropriate care by informed professionals. Being involved in the Irish Sarcoma Group is a great opportunity to advance this and collaborate with colleagues across the country with a similar aim.
