The incidence of pancreatic neuroendocrine neoplasms (PanNENs) has been increasing worldwide due to improved disease recognition and advances in diagnostic modalities such as computed tomography and endoscopic ultrasound. The number of older adult patients with PanNENs is expected to increase in Japan's rapidly aging society. Therefore, it is important to establish treatment strategies for older adult patients. The only curative treatment for PanNENs is surgical resection, which can be safely performed in older adult patients when selected appropriately. Depending on age, comorbidities, and tumor size, nonsurgical management, such as observation and systemic therapy, should also be considered. Systemic therapies, including somatostatin analogs, targeted therapies, cytotoxic chemotherapy, and peptide receptor radionuclide therapy, are available for patients with unresectable or metastatic pancreatic neuroendocrine tumors (PanNETs). When administering these therapies to older adult patients with PanNETs, it is important to balance the treatment, and the adverse events which can be linked to it, with the patient's comorbidities and cognitive function. Further studies on older adult patients with PanNETs are warranted to establish an optimal treatment strategy.
