Congrès SFRO · 2026

Agoris analysis · updated September 2026

Key takeaways

• The SFRO Congress is the annual gathering of the Société Française de Radiothérapie Oncologique (SFRO), the learned society for radiation oncologists. It is a medical congress: scientific sessions, industry symposiums and an integrated professional exhibition, held both in person and remotely.
• Next edition: the 37th, from Wednesday 4 to Friday 6 November 2026, at CNIT Forest, in Paris La Défense. Opening at 2:00pm on Wednesday, closing at 4:00pm on Friday, according to the SFRO's agenda.
• Organiser: the Société Française de Radiothérapie Oncologique (SFRO), a French non-profit association (under the 1901 law). Organisation is entrusted by mandate to the agency MCI group France, which manages registrations, the exhibition and partnerships.
• Annual frequency. In recent years, the congress has alternated between Paris (2022, 2024, 2026) and a regional city (Montpellier in 2023, Bordeaux in 2025).
• Results of the 2025 edition in Bordeaux: 1,400 participants, 272 presentations and 52 partners. For 2026, the organiser announces 70 partners and an exhibition area of 1,800 sqm.

Who exhibits

Typical profile

The organiser presents the exhibition area as an integral part of the congress: a meeting point between medical industry companies and healthcare professionals, housed in the same building as the session rooms. Access to the exhibition is included in congress registration: registered participants pass through between sessions, during breaks and over lunch.

The 2026 exhibition plan outlines two families. On one side, suppliers to the radiotherapy technical platform: equipment, treatment-planning and quality-control software, brachytherapy, and artificial intelligence applied to treatment. On the other, pharmaceutical companies active in oncology, a logical fit for a congress where combining radiotherapy with systemic treatments is among the topics for submitted abstracts. These are joined by players in digital health, hadron therapy and healthcare institutions.

Notable exhibitors

The 2026 exhibition plan lists 52 exhibitors as of late September 2026. On the equipment and software side, these include Accuray, Brainlab, Elekta, IBA, RaySearch Laboratories, Siemens Healthineers, Vision RT, PTW-France, Eckert & Ziegler BEBIG, Orfit Industries, ScandiDos, MIM Software, TheraPanacea and Aquilab By Coexya. On the pharmaceutical side: AstraZeneca, Bayer, MSD, Novartis Pharma, Ipsen, Astellas Pharma, Merck, Johnson & Johnson and Accord Healthcare. The list also includes the Assistance Publique - Hôpitaux de Paris and CYCLHAD.

The 2026 partners page ranks them by tier. Platinum partners: AstraZeneca, Bayer and Varian Medical Systems France. Gold partners: Astellas Pharma, IBA, Ipsen, Johnson & Johnson and MSD. Silver partner: Accuray. Bronze partners: Brainlab, Elekta, Qualimedis, RaySearch Laboratories, SEEmed and Vision RT.

Visitor quality

The audience is that of an entire specialty. The organiser addresses the whole community: radiation oncologists, medical physicists, radiotherapy technologists, quality officers and researchers, with a reduced rate for junior members, medical physicists, technicians, radiotherapy technologists and quality officers, and a dedicated rate for SFjRO members. The SFRO has more than 800 members, and notes that around 175,000 patients are treated by radiotherapy in France each year.

The audience is predominantly French but distinctly French-speaking. Of the 1,400 participants in 2025, 1,051 came from France, 70 from Morocco, 31 from Belgium, 26 from Algeria, 25 from Switzerland, 16 from Canada, 15 from Germany and 13 from Tunisia. These figures are provided by the organiser, with no published third-party audit, and the hybrid format does not allow on-site attendees to be distinguished from remote participants.

Events & community

Conference programme

The 2026 programme, announced by the chair of the scientific council, is built around flagship sessions: a session on re-irradiation as part of the partnership with ESTRO, a session on brachytherapy, a discussion on treatment de-escalation, a session on breast cancer and a joint session with the AFU on bladder cancer. Non-tumoral and rare indications are also announced.

The congress also devotes considerable space to care organisation: a session on billing reform and the PLFSS (the annual social security financing act), a presentation on the demographics of radiotherapy professionals, sessions on inclusion and diversity, carers' mental health and artificial intelligence. The RadioTransNet sessions, the AFPPE and AFQSR workshops, and the young researchers' sessions, including "ma thèse en 180 secondes" ("my thesis in 180 seconds"), are returning.

The formats are described on the website: plenary sessions, symposiums, oral presentations selected by the scientific committee, the Théâtre Forum and social moments. The 2026 abstracts covered 25 topics, from re-irradiation to hypofractionation, from adaptive radiotherapy to stereotactic treatment. The interactive programme is online.

Symposiums and hybrid format

For an industry player, the main lever is the symposium: symposiums are time slots reserved for industrial or institutional partners, integrated into the scientific programme, to present therapeutic innovations or study results.

As in 2025, the 2026 edition is hybrid. On-site registration includes access to the session rooms and the exhibition, replays for three months, and online access to the special issue of the journal "Cancer Radiothérapie". A remote-only registration is also offered, without access to the exhibition.

Community & networks

The SFRO works with the societies neighbouring its specialty: ESTRO, of which SFRO members are also members, the AFU for the 2026 joint session, the AFPPE and AFQSR for the workshops, the RadioTransNet network, and the SFjRO, with which the SFRO developed the Radiosync app. The learned society also draws up the specialty's professional recommendations, published in its journal "Cancer Radiothérapie".

The congress evening event takes place on Thursday 5 November 2026 at 8:15pm, at the Hôtel Le Marois, avenue Franklin Delano Roosevelt in Paris, around a dinner cocktail. Rates: €80 incl. VAT for participants, €30 incl. VAT for SFjRO members, €120 incl. VAT for exhibiting partners and sponsors.

The SFRO was founded in 1990 out of the need to bring together professionals whose training and practice differ from those of medical oncologists and radiologists: medical imaging has its own event, the JFR.

On site: what you need to know

The congress is held at CNIT Forest, 2 place de la Défense, in Puteaux, at the heart of the La Défense business district. Access by public transport is via the La Défense - Grande Arche stop, exit 4 Parvis Esplanade: metro line 1, RER A, tramway T2 and Transilien lines L and U. From the main Paris stations, the RER A goes directly to La Défense.

By car, parking at CNIT Forest is charged at €4.40 an hour. From Charles-de-Gaulle airport, allow 30 minutes by taxi, or take the RER B then the RER A; from Orly, 40 minutes by taxi, or Orlyval, RER B then RER A. Several Vélib stations are nearby.

CNIT Forest is 100% accessible to people with reduced mobility, including session rooms and exhibition spaces. Pre-registered attendees collect their badge at self-service kiosks using the QR code received by email; counters welcome new registrations throughout the congress. For accommodation, Revolugo is the official partner agency for individual bookings, and the congress secretariat handles group bookings from ten people upwards.

How much it costs to exhibit

Preparing your visit

For exhibitors

• Request the commercial brochure via the partners form: this is the only entry point to stand and symposium rates.
• Plan ahead: sales for the 2026 edition opened on 15 September 2025, even before the Bordeaux edition. On a learned-society congress, the best spaces and symposium slots sell out early.
• Check the compliance framework: the 2026 congress is declared compliant with the MedTech Europe code under number EMT-25-07666, which matters for medical device companies subject to the Conference Vetting System.
• Prepare materials in French: abstracts submitted in French are favoured and the audience is primarily French-speaking.
• Budget for additional badges, at €104.50 incl. VAT per person.

For decision-making visitors

• Register before 26 October 2026: €305 incl. VAT for an SFRO member, €550 incl. VAT for a non-member. From 27 October, the rate rises to €325 and €605 incl. VAT.
• Choose between on-site and remote attendance: only on-site registration gives access to the exhibition and to industry exhibitors.
• Plan your route using the interactive programme, and identify the symposiums of suppliers whose solutions you are evaluating.
• Lunches on Thursday and Friday are included in on-site registration, leaving time for the exhibition area.

CSR policy & initiatives

The documented commitment sits at the level of the organising agency. On the congress's CSR page, MCI group France states that it has been ISO 20121 certified since 2022 and applies a responsible purchasing policy. For the congress, it announces actions to reduce the carbon footprint through logistics and digital tools, the choice of committed suppliers, and inclusion and diversity initiatives.

Concrete measures are specified: the final programme is not printed and stays online, no posters or flyers are printed, and conference bags were dropped in 2026. The same page details the approaches of the selected service providers, including Viparis, ISO 20121 certified since 2014 with its Better Events - Viparis 2030 programme, and the printer ICA, PEFC and FSC certified.

On the venue side, CNIT Forest was renovated using materials from responsible supply chains, is 100% LED-equipped, has removed single-use plastic from its listed caterers, and offers empty-packaging management for exhibitors as well as consolidated logistics to limit freight. According to the same page, its location at the heart of La Défense's transport hub favours active and low-carbon travel.

This agency- and venue-level commitment should be distinguished from a certification specific to the event itself: no ISO 20121 certification of the congress itself is displayed. The environmental question has, however, fed into the scientific programme: in 2023, under the theme "Innover durablement" ("Innovating sustainably"), the Montpellier congress devoted a session to the energy sobriety of radiotherapy departments, in partnership with The Shift Project.

How the congress has evolved

Trajectory analysis

The SFRO, founded in 1990, brings its community together every year, and the 2026 edition is the 37th. Since 2022, the calendar has followed a discernible pattern: Paris in even years, at the Palais des Congrès de Paris in 2022 then at CNIT La Défense in 2024 and 2026, and a regional city in odd years, at Corum de Montpellier in 2023 and at the Palais des Congrès de Bordeaux in 2025. The organiser does not present this as a rule, but spoke in 2025 of a choice made once again in favour of the regions.

The only published set of figures is from 2025: 1,400 participants, 272 presentations and 52 partners. The 70 partners expected in 2026 are an announced target, not a result, and the exhibition plan counts 52 just over five weeks before opening.

The congress's content is also shifting from the purely technical towards care organisation: billing, workforce demographics, carers' mental health, artificial intelligence. For an industry player, this is a useful signal: the programme speaks as much to department heads as to treatment-technique specialists.

The venue and dates for the 2027 edition had not been announced at the time of writing.
