The 27th EORTC–ESMO–AACR Workshop on Methods in Clinical Cancer Research (MCCR 2027) will take place on June 20–24, 2027, at De Ruwenberg Hotel in Sint-Michielsgestel, Netherlands. The workshop is jointly organized by the European Organisation for Research and Treatment of Cancer (EORTC), European Society for Medical Oncology (ESMO), and American Association for Cancer Research (AACR).

The five-day intensive training programme is designed for early-career clinical investigators seeking to strengthen their expertise in designing and conducting cancer clinical trials. Participants will have opportunities to learn from experienced researchers and gain practical knowledge of clinical research methodology, study design, and the development of scientifically rigorous trial protocols.

Established in 1999, the workshop has trained more than 2,000 investigators from around the world and continues to support the next generation of oncology research leaders. The programme encourages mentorship, international collaboration, and the development of high-quality clinical research projects that can contribute to advances in cancer treatment and patient care.
