A User Guide to Cancer Immunotherapy is a practical one-day meeting focused on the recognition and management of immune-mediated toxicities. The Royal Marsden describes a strong clinical emphasis, with guidance intended for daily practice. The audience includes doctors, nurses, pharmacists and physician associates working in oncology, acute medicine, emergency medicine, other medical specialties and general practice, so the content is potentially useful to resident doctors who encounter patients receiving immunotherapy outside specialist oncology services. The official page currently says the programme is to be published soon and links a PDF carrying the event information; no detailed timetable or named faculty is yet available from the rendered page. No abstract-submission route, attendee presentation type or publication outcome is advertised. The full-delegate fee is £200 and the trainee/CNS rate is £150, with no student fee, early-bird period or registration deadline stated. Royal College of Physicians CPD points have been applied for but are not yet confirmed. The meeting runs from 09:00 to 17:00 at the Royal Marsden Education and Conference Centre in Chelsea, with a Tito booking page confirming the date and venue.
