The MASCC/ISOO 2027 Annual Meeting will take place from June 24–26, 2027, in Rotterdam, the Netherlands.

Organized by the Multinational Association of Supportive Care in Cancer (MASCC) in partnership with the International Society of Oral Oncology (ISOO), the meeting is an international and interdisciplinary conference focused on supportive cancer care.

The 2027 meeting will be held under the overarching theme “Optimizing Cancer Care Through Supportive Care for All: From Conceptualization to Implementation.” The programme will address developments across supportive oncology, including digital innovation, patient-centered care, disparities in cancer care, research implementation, biomarkers, and toxicity prediction.

The meeting will bring together clinicians, researchers, trainees, students, patient partners, and industry representatives to exchange knowledge, present research, develop collaborations, and discuss approaches to improving supportive care throughout the cancer journey.
