*Metastases were confirmed by the comprehensive consideration of imaging findings and pathologic results.
↵^†Metastases at uncommon sites.
IS = initial staging; PDAC = poorly differentiated adenocarcinoma; PM = peritoneal metastasis; LNM = lymph node metastasis; OM = ovarian metastasis; SRCC = Signet ring cell carcinoma; LM = liver metastasis; BM = bone metastasis; RD = recurrence detection; PD = progression of disease.
