ESMO stands for the European Society for Medical Oncology, the leading European professional organisation for medical oncology. Founded as a Swiss-registered non-profit organisation headquartered in Lugano, Switzerland, ESMO represents more than 50,000 oncology professionals across more than 170 countries. The society advances oncology research, establishes clinical practice guidelines, administers European medical oncology board certification, and disseminates clinical trial findings through its flagship annual congress and peer-reviewed journals.
What ESMO Is and Who Operates It
The European Society for Medical Oncology (ESMO) operates as a Swiss-registered not-for-profit professional society headquartered at Via Ginevra 4, 6900 Lugano, Switzerland. ESMO is governed by an elected Executive Board and Council representing clinicians, translational researchers, clinical trialists, and allied healthcare professionals across oncology specialisms. Funding for the society’s operational and educational programmes is managed directly through membership subscriptions, educational grants, congress registrations, and publication partnerships.
While cancer care crosses numerous therapeutic domains, oncology practice distinguishes medical oncology—centred on systemic therapies, targeted therapeutics, and immunotherapies—from surgical and radiation disciplines. Researchers comparing disciplinary structures can explore our analysis of oncology vs hematology to understand how solid tumour oncology coordinates with malignant hematology protocols.
What Does ESMO Do? Core Activities and Research Tools
ESMO provides the methodological infrastructure that translates oncological discoveries into standardised clinical practice. Its core operational functions include:
- Clinical Practice Guidelines: ESMO convenes international expert panels to author and regularly update evidence-based clinical practice guidelines across solid tumours and hematological malignancies. These guidelines set European standards for diagnostic staging, biomarker testing, and systemic treatment regimens.
- ESMO Magnitude of Clinical Benefit Scale (ESMO-MCBS): A validated, reproducible grading system designed to evaluate the clinical benefit of new anticancer therapeutics approved in clinical trials. ESMO-MCBS applies distinct forms for curative and non-curative settings, scoring therapies based on overall survival, progression-free survival, quality of life, and treatment toxicity.
- ESMO Scale for Clinical Actionability of molecular Targets (ESCAT): A genomic classification framework ranking tumour genomic alterations (from Tier I to Tier X) according to the strength of clinical evidence supporting targeted therapeutic interventions.
- Annual Scientific Congresses: Organising global and regional oncology meetings, including the flagship ESMO Congress and ESMO Asia, providing platforms for late-breaking clinical trial data disclosures.
Scientific Publishing: Annals of Oncology and ESMO Open
ESMO disseminates oncological science through a portfolio of peer-reviewed journals published in partnership with Elsevier BV. Unlike general medical publications, these journals serve as official dissemination vehicles for practice-changing randomized trials and consensus statements:
- Annals of Oncology (ISSN 0923-7534 / Online 1569-8041): ESMO’s flagship scientific journal, celebrating over 35 years of continuous publication. Led by Editor-in-Chief Thomas Powles (Professor of Urology Cancer at the University of London and Director of Barts Cancer Centre), the journal publishes original oncology research, randomized trial reports adhering to CONSORT flow diagram standards, meta-analyses, and official clinical guidelines. Bibliometric records indexed in OpenAlex record more than 68,000 publications, over 1.15 million citations, and an h-index of 391.
- ESMO Open (ISSN 2059-7029): An open-access peer-reviewed companion journal dedicated to rapid publication of clinical and translational cancer studies, real-world oncology datasets, and health policy analyses, with more than 8,500 indexed publications and over 60,000 citations.
What Is ESMO Certification? The ESMO Examination and MORA
ESMO certification provides an internationally recognised benchmark of core competence for medical oncologists:
- The ESMO Examination: Administered annually by the ESMO Examination & Accreditation Working Group (for example, held on Saturday 24 October 2026 alongside parallel international sessions), this standardised written exam evaluates clinical oncology expertise against European training curricula. Candidates who achieve a passing mark receive formal ESMO certification in medical oncology.
- ESMO-MORA Recertification: ESMO certification is valid for a defined period. To maintain certified status without re-taking the examination, clinicians participate in the Medical Oncologist’s Recertification Approval (ESMO-MORA) programme, which logs continuing medical education (CME) credits across accredited conferences, guideline study, and educational coursework.

How to Become an ESMO Member
Oncology professionals, researchers, and students apply for ESMO membership through a standardised online workflow:
- Create a myESMO Profile: Register on the official portal (esmo.org) with professional contact details and primary institutional affiliation.
- Select Membership Category: Select the applicable professional category based on clinical role, research appointment, or commercial employment.
- Submit Supporting Documentation: Upload verification documents, such as medical diplomas, institutional proof of employment, residency verification, or student enrollment confirmation.

Upon verification by the ESMO Membership Committee, member benefits—including online guideline access, journal subscriptions, and congress discounts—become active.
Annual Conferences and Meetings: Where Is ESMO 2026?
The flagship scientific event is the ESMO Congress, which rotates among major European conference centres. The ESMO Congress 2026 will take place from 23 to 27 October 2026 in Madrid, Spain at IFEMA MADRID, featuring both in-person sessions and interactive access through a dedicated virtual congress platform.
In addition to its European flagship congress, the society hosts regional meetings such as ESMO Asia, specialized disease symposia (covering breast, lung, and gastrointestinal cancers), and collaborative trials workshops. Researchers monitoring translational trial benchmarks can also consult major multi-institutional resources, including cancer research funding programs, public awards from the National Cancer Institute (NCI), population imaging initiatives like the National Lung Screening Trial, and genomic cohorts in The Cancer Genome Atlas (TCGA).
