Early metastasis is one of the important factors for poor prognosis of pancreatic cancer. Early detection of abdominal metastasis can urge patients to undergo neoadjuvant therapy and conversion therapy as soon as possible and avoid unnecessary surgical trauma. This paper reviews the diagnostic efficacy of imaging methods, laboratory methods and combined multi-mode comprehensive evaluation in patients with abdominal metastasis of pancreatic cancer, briefly describing the application of computed tomography, magnetic resonance imaging, ultrasound, tumor markers, microRNA and other methods, and summarizing the use of multi-index comprehensive evaluation to improve the ability of metastasis risk prediction, so as to provide reference for the selection and application of clinical diagnostic methods.
