RESUMEN
PURPOSE: The SEOM Future Plan is aimed at identifying the main challenges, trends and needs of the medical oncology speciality over the next years, including potential oncologist workforce shortages, and proposing recommendations to overcome them. METHODS: The estimations of the required medical oncologists workforce are based on an updated Medical Oncologist Register in Spain, Medical Oncology Departments activity data, dedication times and projected cancer incidence. Challenges, needs and future recommendations were drawn from an opinion survey and an advisory board. RESULTS: A shortage of 211 FTE medical oncologist specialists has been established. To maintain an optimal ratio of 158 new cases/FTE, medical oncology workforce should reach 1881 FTE by 2035. CONCLUSIONS: Main recommendations to face the growing demand and complexity of oncology services include a yearly growth of 2.5% of medical oncologist's workforce until 2035, and development and application of more accurate quality indicators for cancer care and health outcomes measure.
