It is relatively difficult to have preoperative diagnosis due to the lack of specific tumor markers and pre-operative images.Methods: In the present study, database of the pancreas center in the First Affiliated Hospital of Nanjing Medical University was retrospectively screened. A total of thirteen cases diagnosed as undifferentiated carcinoma of pancreas with osteoclast-like giant cells were included. Their clinical data and treatments were collected.Results: Thirteen patients include eight males and five females, and the median age was 67 (60– 72) years old. The lesions were found in more than half patients through health examination with no symptoms. NSE was elevated in eight cases (66%). CT scan revealed that cystic and solid lesions often had thick (4/5), contrast-enhanced (5/5) wall with smooth edges (5/5) and the boundary of lesions mainly with solid composition (4/10) is not well demarcated with normal pancreatic parenchyma. All patients received surgical resection. Eight patients had adjuvant chemotherapy and only one patient had adjuvant radiotherapy. The median survival time was 13 months. Five patients had postoperative metastasis or recurrence of tumor and four of them had died of this disease during follow-up.Conclusion: Our data showed that elevated level of NSE and characteristic pre-operative images might provide aid with the pre-operative diagnosis for undifferentiated carcinoma of pancreas with osteoclast-like giant cells. Patients with suspected diagnosis should receive surgical intervention as soon as possible, supplemented with postoperative chemotherapy, in order to prolong the survival of patients.Keywords: pancreatic cancer, undifferentiated carcinoma of pancreas, osteoclast-like giant cells, retrospective, pre-operative image
