Abstract:
Objective To investigate the diagnosis and treatment of solid-pseudopapillary tumor of pancreas (SPTP). Methods The clinical manifestations, imaging findings, treatment and prognosis of 36 patients with SPTP from September 2005 to December 2015 were retrospectively analyzed. Results All patients were female, with the average age of 30.5 years. There were 11 cases of abdominal mass and 15 cases of abdominal tenderness. Thirty-three patients underwent ultrasonography, which showed pancreatic solid heterogeneous hypoechoic, echogenic light clusters or cystic mixed echogenic masses;the tumors boundary were clear, and some tumors were separated in the center; most tumors were not accompanied by pancreatic duct and bile duct dilatation. CT plain scan showed that most tumors were single circular mixed density shadow with clear capsule;CT enhanced scan showed that the arterial phase of the cyst wall and solid area was mild or moderately enhanced, and the portal phase and the delayed phase continued to strengthen, and the cystic part was not strengthened in each period. All patients underwent surgical treatment. Postoperative pancreatic fistula occurred in 8 cases, edematous pancreatitis in 6 cases, incision infection in 2 cases, all of which were cured after symptomatic treatment. The patients were followed up for 5 to 120 months with an average of 56 months. All patients were not treated with postoperative radiotherapy or chemotherapy. Thirty-four patients had a good prognosis and no signs oftumor recurrence and metastasis;1 patient died of acute leukemia 2 months after discharge, and 1 patient was lost in follow-up after 1 year of postoperative liver metastasis. Conclusions The main patient group of SPTP is young women. The clinical symptoms are mostly abdominal mass and tenderness. Preoperative diagnosis is difficult. Imaging examination is great significance for the preoperative diagnosis of SPTP. Surgical resection is the only effective treatment. The choice of surgery should be based on the location of the tumor, the invasion tendency of the tumor seen during surgery, and the rapid pathology of the operation. Most patients with SPTP have a good prognosis, and the recurrence rate and metastasis rate are low.
