Metastasi ossee nei tumori neuroendocrini: epidemiologia, presentazione clinica e risvolti terapeutici
摘要
Neuroendocrine tumours (NEN) are an heterogeneous group of rare and tendentially indolent neoplasms. Metastases from neuroendocrine tumours often transcend their sites of origin. The most frequent sites are liver, lymph nodes, lungs and bone. Bone metastases (BM), which were once thought to be extremely rare, have now increased thanks to improved imaging techniques, including PET Ga 68. Usually indolent, they can however lead to pain, pathological fractures and spinal cord compression. The presence of MO at diagnosis worsens the disease prognosis. Management requires an integrated approach with systemic therapies, radiotherapy, PRRT and anti-resorptive agents. Although specific guidelines are lacking, increased awareness among experts and targeted screening strategies are crucial for improved management.
