Sophie Hartley (Patient Advocate)
I was diagnosed with Ewings Sarcoma in my right distal femur on 21 April 2005, age 8. I received Euro-Ewings99 treatment protocol and a full knee replacement. I later had leg lengthening surgeries to correct the discrepancy as I grew through puberty, including an illazrov frame. Now, I work for the leading children and young people's cancer charity in the UK in the fundraising team and share my story to help the next generation of childhood cancer patients.

Dr Javier Martin-Broto
Sarcoma Medical Oncologist at the University Hospital Fundacion Jimenez Diaz (Madrid, Spain). I founded and currently lead the Research Group ATBsarc devoted to Sarcoma Research at CITIUS III (Seville, Spain). I studied Medicine between 1982 and 1988, obtaining the official title of Specialist in Medical Oncology in 1994 after successfully passing a national exam. I obtained PhD degree on Molecular Biology in 2010. From 1994 to current I devoted to sarcoma care in different Hospitals (Hospital Son Dureta/Son Espases & Hospiral Universitario Virgen del Rocío). Those Hospital became part of Center of Reference for Sarcoma. Likewise, HUVR is one accredited within ERN (European Network for Rare Diseases) as European Center of Reference in Sarcoma from 2017. I have fought for the activation of the accreditation process in sarcoma centers, systems and reference units (CSUR) of the National Health Service in Spain. During my stay at the HU Virgen del Rocio I worked actively to achieve accreditation for this center.
Since the beginning of my career, my activity has combined clinical care and research (clinical, translational and preclinical) with teaching activities. My preclinical and translational activity has served as a rationale to develop a large number of international academic clinical trials as principal investigator -I've been the PI of the Research Group TERABIS at the Instituto de Biomedicina de Sevilla (IBIS) since 2014 to 2021-. Additionally, I have participated as an investigator in more than 60 clinical trials in sarcomas. All this activity is reflected in more than 134 scientific articles and in my participation in numerous national and international congresses and meetings (an average of more than 50 per year).
Additionally, I am a Founder Member of the Spanish Group for Research on Sarcomas (GEIS) and currently vice-chairman of this group from 2019 (Chairman from 2010 to 2018). Member of ASCO, ESMO (where I am chair of sarcoma track and ESMO Faculty member in Sarcomas from 2010 ), CTOS (member of board directors of CTOS from 2014 to 2018), SEOM and member of Steering committee of EURACAN network.
Currently I combine clinical sarcoma assistance with translational research, leading a basic research team in the lab. Additionally, I am running and designing several trials on sarcoma patients, some of them as coordinator at national and international level. I am leading the consortium SELNET through Horizon 2020 grant; this network involves Latin-American and European countries. My career has always been committed to excellence in healthcare, research and academia.
