ABSTRACT

Objective To summarize the experience of diagnosis and treatment of solid-pseudopapillary tumor of pancreas (SPTP).Methods The clinical data of 15 patients with SPTP who were treated in our hospital from March,2003 to March,2006 were analyzed retrospectively.Results The 15 cases were all women, and the average age was 29.4 years.The chief manifestations were abdominal mass, abdominal pain or other abdominal discomfort. None of the 15 cases had history of pancreatitis or abdominal trauma, and no long history of drinking or smoking. Six cases were negative for CEA,CA50,CA199,CA125 and other tumor markers.Solid and solid-cystic masses in pancreas or solid and solid-cystic tumors in retroperitoneum were found both by B-mode ultrasonography and CT examinations. Preoperative fasting blood sugar was within normal limits. The tumor in 8 cases was located in the pancreatic head, in 6 cases was in the body and tail of pancreas, and in 1 case was in the neck of pancreas. The diameter of the tumors was 2.5-10 cm. No metastasis was found in the abdominal cavity or liver. Local excision was performed in 6 cases, distal pancreatectomy was performed in 5 cases, including 2 cases combined with splenectomy, and pancreaticoduodenectomy was performed in 3 cases, segmental pancreatectomy was performed in one patient with tumor in the neck of pancreas. The 15 cases showed typical pathologic manifestation of SPTP by microscopy. At followed up for 16-52 months, no evidence of recurrence or metastasis in these cases was found.Conclusions Solid-pseudopapillary tumor of pancreas primarily affects young women, and it may be located in any part of pancreas. Surgical resection is recommended as the treatment of choice, and the prognosis is good.
