Firstly, the Neuroendocrine tumor teaching units allow to delve into the epidemiology and historical evolution of these tumors, explore their classification, and examine their pathological basis. The participant will then understand the clinical presentation and role of molecular imaging techniques such as PET/CT, as well as to learn about treatment response evaluation to peptide receptor radionuclide therapy (PRRT) using SPECT/CT and the significance of biomarkers. Secondly, in the prostate cancer teaching units, the participants will explore the epidemiology and historical evolution of the disease, examine its tumor classification, and focus on pathology and genomics. This will allow to gain insights into molecular imaging techniques, with a specific focus on PSMA PET/CT, including potential pitfalls, as well as to understand treatment response evaluation to PRRT using SPECT/CT and the significance of PSA as a tumor marker. Systemic therapy guidelines and basic principles of PRRT will be covered for both cancer types above. Finally, radioiodine therapy and its application in thyroid cancer will be introduced.
