Welcome letter

“

It is with great pleasure that we welcome you to the first edition of the «ESTRO meets Asia» conference in Singapore. The «ESTRO meets Asia» conference has the objective to bring radiation oncology collaboration between Europe and Asia to a new level - regarding science, education, technology and professional development, targeting all professionals working in

the discipline (clinicians, medical physicists, RTTs and radiobiologists).

The interactive conference format is designed to enable participants to share experiences on practices/operations from both regions and discuss how to facilitate collaboration. The conference will be a platform where participants will learn from each other by embracing the diversity of clinical practices and exploring the development of common solutions to optimise radiotherapy treatment and care for all patients. The scientific programme, designed in collaboration with FARO and specialists from the Asian region, will be made up of three components: an interdisciplinary component, a radiobiology component and a component focusing on the practice of medical physicists and RTTs. The interdisciplinary component of the conference will offer teaching lectures, symposia and proffered papers on the latest advancements on the topics of:

• Head and Neck (oropharynx) • Rare tumours (lymphoma) • Anal canal / rectal cancer • Pelvic / gynaecological tumours • Thorax (breast and lung cancer)

The radiobiology component will draw from the ESTRO Basic Radiobiology Course and will cover mainly: • A series of basic lectures introducing molecular and clinical radiobiology

• Mechanisms and models or radiation cell killing • The linear-quadratic approach to fractionation • Molecular basis of radiation response • Radiobiology and tolerance of normal tissues to (re)treatment

Programme and Exhibition Guide | GENERAL INFORMATION

• Alternative fractionation schedules in radiotherapy • Tumour hypoxia and the microenvironment • Combined radiotherapy and chemotherapy • The volume and dose-rate effect in radiotherapy • Biological response modifiers (tumours, normal tissues) and molecular approaches to therapy • Protons and other particles in radiotherapy • Radiation-induced malignancies. The third component of the conference is focusing on the practice of medical physicists and RTTs and will cover topics such as: • IGRT, patient positioning and immobilisation • Dosimetry, audit and risk assessment • Brachytherapy The conference will also include round table discussions on the organisation of education, training and certification as well as sessions linked to ongoing projects such as HERO (Health Economics in Radiation Oncology); GTFRCC (Global Task Force on Radiotherapy for Cancer Control) and GIRO (Global impact of radiotherapy in oncology) under the overall umbrella of advocacy.

ESTRO and FARO look forward to your active participation in this conference.

About ESTRO

ESTRO Vision 2030 The governance of ESTRO is pleased to share with you the 2030 vision that has been officially presented at ESTRO 37 in Barcelona last April.

The 2030 vision will set the roadmap to follow for the further development of the discipline of radiation oncology.

ESTROMission Founded in 1980, ESTRO is a non-profit scientific organisation whose role is to foster, in all its aspects, radiation oncology, clinical oncology and related subjects, including physics as applied to radiotherapy, radiation technology and radiobiology. To fulfill its purpose, ESTRO promotes education, science, research and advocate for access to radiotherapy through its teaching courses, workshops, meetings, publications and public affairs activities. ESTRO School The ESTRO School has become an internationally recognised provider of high quality education in radiotherapy and oncology and has developed a wide array of educational activities: • Live teaching courses covering basic and continuing medical educational needs of all professionals working in the field of (radiation) oncology • Pre-meeting teaching courses, workshops, teaching lectures and tumour boards during congresses

GENERAL INFORMATION | Programme and Exhibition Guide

• Live and online workshops courses with FALCON (Fellowship in Anatomic deLineation and CONtouring), the online delineation programme • Hands-on experience through mobility grants programme. The ESTRO School promotes multidisciplinary education in oncology, basic science, physics and technology, imaging, and interdisciplinary oncology, with the objective of standardising knowledge and clinical practice, whilst recognising the diversity of radiation oncology practice in different parts of the world. In 2019, the ESTRO School is organising 41 live courses (33 in Europe and 6 outside Europe) and 2 undergraduate courses. More information on the 2019 course programme on www.estro.org

ESTRO Conferences ESTRO next annual conference: ESTRO 38 26-30 April 2019 | Milan, Italy

About FARO

The Federation of Asian Organizations for Radiation Oncology (FARO) was founded in 2014 as a non-profit and scientific organization. FARO is intended to function as a federation of radiation oncology societies in Asia and aims to foster the role of radiation oncology to improve the basic level of radiotherapy for the benefit of the patients in the Asian region. Asia is a major part of the global community (more than 50% of the world population) and at the same time the most heterogeneous and diverse region. FARO has 12 member societies (the national radiation oncology societies from Bangladesh, China, India, Indonesia, Japan, South-Korea, Malaysia, Philippines, Singapore, Sri Lanka, Thailand and Pakistan) and plans to continue to grow bigger and stronger as time goes by. The mission of FARO is to promote innovation, research, and dissemination of science and technology through its congresses, special meetings, educational courses and publications. The aims and purposes of the Federation are : 1. To promote the co-operation and communication between Radiation Oncology Organizations in the region 2. To develop the standard of education/training and research irradiation oncology and related field in the region 3. To promote the advancement in status and standard of practice of the radiation oncology profession 4. To organize and/or sponsor international conferences, regional and other meetings or courses 5. To collaborate or affiliate with other scientific or professional Organizations.

FARO has organised 3 meetings so far: • Kyoto (JP), 25-27 November 2016 • Bangalore (IN), 9-10 November 2017 • Bali (Indonesia) 6-8 September 2018
