Solid pseudopapillary tumors of the pancreas are generally considered to be junctional tumors, that is, tumors that are between benign and malignant, or are of low malignancy. These tumors are mainly expansile in growth, but can become cancerous as they grow and can invade, break through the envelope, and infiltrate into surrounding tissues, blood vessels, and organs. This tumor can also metastasize to the liver through the superior mesenteric vein, portal vein, etc. Solid pancreatic pseudopapillary tumors are not very sensitive to radiotherapy and chemotherapy, and surgical resection is the most effective treatment, even for those with liver metastases. The progression of pancreatic solid pseudopapillary tumor is very slow and the prognosis is relatively good. Even if the tumor has metastasized, most patients will survive for more than 5 years.
