General
=========================================================================

● Secondary pancreatic tumors usually occur by direct extension, not metastatic spread
● Primary site of metastases most commonly lung and GI tract (Virchows Arch 2004;444:527)
● Metastases usually are multifocal and lack fibrosis
● Excise metastasis if patient has low surgical risk and curative resection is possible (J Korean Surg Soc 2011;80:278)
