The Special Interest Group for Rare Endocrine Diseases will host a session focusing on rare but clinically significant malignant tumors. Prof. Jung Soo Lim will introduce clinical approaches to adrenocortical carcinoma, and Prof. Dong-Jun Lim is expected to discuss the complexities and treatment limitations of anaplastic thyroid carcinoma. Finally, Prof. Seiji Fukumoto will explore the intersection of bone metabolism and endocrine diseases through the study of rare malignancies causing TIO. We hope this session serves as a meaningful platform to discuss the future of rare endocrine cancer management.

The landscape of thyroid cancer treatment is shifting toward risk-stratified precision medicine. In this session, we will share multicenter data on serum Tg cut-off levels for post-operative management in low-to-intermediate risk groups and discuss clinical strategies for active surveillance during pregnancy. Additionally, we will delve into the role of the tumor microenvironment in overcoming treatment resistance in advanced stages. We invite you to join us for an insightful overview of the evolving paradigms, spanning the entire spectrum from low-risk management to high-risk therapeutic interventions.
