Cancer Grand Challenges Conference: extrachromosomal DNA

REGISTRATION NOW OPEN

About

Date: 11 June, 2025 - 13 June, 2025

Location: The Royal Society, 6-9 Carlton House Terrace, London SW1Y 5AG UK

Join us at the first edition of the Cancer Grand Challenges Conference Series, where we'll be convening researchers around the globe to discuss extrachromosomal DNA (ecDNA) — a field that Cancer Grand Challenges put in the spotlight, setting the extrachromosomal DNA challenge in 2020, and funding team eDyNAmiC, led by Paul Mischel.

Scientific Steering Committee

This conference is being organised by a dedicated steering committee, chaired by:

Dr Paul Mischel

Meet the committee members below.

ecDNA

ecDNA has emerged as one of the most pressing and challenging problems in cancer. ecDNAs, oncogene-containing circular DNA fragments found outside of chromosomes, play a crucial role in cancer development and progression. ecDNAs allow cancer cells to quickly evolve and adapt to changing environments and treatments, and thus are a significant clinical problem, as major contributors to treatment resistance and poor outcome. Conceptually ecDNA biology is fascinating – sitting at the interface of genetics and epigenetics. ecDNA biology is also vitally relevant - being linked to treatment resistance and poor outcome in patients. Understanding and exploiting ecDNA biology promises to transform the fundamental understanding of cancer and potentially revolutionise its treatment.

Although first observed over 50 years ago, the importance of ecDNA in cancer has only recently come to light, with the field undergoing a revolution, making major leaps towards understanding mechanistically how ecDNAs form and function, how they evolve to resist treatment, how they impact the immune system, and critically how they can be effectively targeted therapeutically.

The conference

This first edition of the Cancer Grand Challenges Conference Series aims to convene researchers from diverse backgrounds, from bench to bedside, across and beyond the ecDNA field, to provide an interdisciplinary forum to stimulate discussion around emerging concepts, open questions, what we need to do to answer them, and the future for this exciting field. The tools, datasets, pioneering technologies, and experimental models have now matured to an extent that the field is ripe for innovation as new investigators enter the field. The purpose of this meeting, in addition to sharing cutting edge science, is to further enhance and build upon an open, collaborative, and inclusive community that will advance the science rapidly for the benefit of patients.

Starting from the basic mechanisms of formation, maintenance and function, touching on transcription, replication and inheritance, and discussing where ecDNAs hijack existing processes and where they’ve put new mechanisms in place. Moving to how ecDNAs are involved in different cancers, and their implications for understanding tumour initiation, progression, evolution and resistance to treatment. The conference will also showcase novel technologies to generate, manipulate and study ecDNAs in human and animal tissues, bioinformatic tools to detect ecDNAs, as well as chemical probes as tools to understand and target ecDNA.

Speakers

More to be announced.

Topics

Topics will include: 

  • Exploring how ecDNAs originate 
  • Understanding how ecDNAs function 
  • How ecDNAs contribute to cancer development and evolution? 
  • How do ecDNAs contribute to therapy resistance? 
  • How does ecDNA evade and manipulate the immune system? 
  • Clinical impact of ecDNAs 
  • How can ecDNAs be targeted therapeutically? 
  • What tools are available to study ecDNAs? 

Registration

Registration is now open and will close on 5 May 2025. We encourage you to register early to secure your place, as capacity is limited. 

Please note that registration for this conference is a two-step process:

  1. Through Eventbrite, you will select a ticket and provide your first name, last name, email address and payment. At this point, your registration is still pending
  2. You will receive an email from Eventbrite containing a link to your tickets and a form with additional questions. Within this form you will have an opportunity to submit an abstract if you wish. Once you have filled out this form, your registration will be complete
Fees

Registration includes VAT, a light breakfast, networking lunch and coffee breaks on all days, and a welcome reception on Wednesday 11 June. See fees below:

Student/PhD/Postdoc £150*
Academic/Clinical £300*
Industry£500*

*These prices do not include Eventbrite's ticketing fee. 

Register via Eventbrite below.

Abstract submissions

We are now accepting abstract submissions from those who wish to speak or present a poster at the conference. The deadline is 23:00 GMT on 14 March, 2025. 

You will have the opportunity to submit your abstract at the point of registration via Eventbrite, after you have provided your first name, last name, email address and payment.

Please note that it is not required to submit an abstract to attend the conference.

Abstract evaluation will start after the deadline and may take up to three weeks to complete depending on the number of submissions we receive. Acceptance notifications will go out promptly after that via email. We appreciate your patience.
