Solid pseudopapillary tumor of the pancreas in male patients: Report of 16 cases

AIM:To investigate the clinical characteristics,surgical strategies and prognosis of solid pseudopapillary tumors(SPTs)of the pancreas in male patients.METHODS:From July 2003 to March 2013,116 patients were diagnosed with SPT of the pancreas in our institution.Of these patients,16 were male.The patients were divided into two groups based on gender:female(group 1)and male(group 2).The groups were compared with regard to demographic characteristics,clinical presentations,surgical strategies,complications and follow-up outcomes.RESULTS:Male patients were older than female patients(43.1±12.3 years vs 33.1±11.5 years,P=0.04).Tumor size,location,and symptoms were comparable between the two groups.All patients,with the exception of one,underwent complete surgical resection.The patients were regularly followed up.Themean follow-up period was 58 mo.Two female patients(1.7%)developed tumor recurrence or metastases and required a second resection,and two female patients(1.7%)died during the follow-up period.CONCLUSION:Male patients with SPT of the pancreas are older than female patients.There are no significant differences between male and female patients regarding surgical strategies and prognosis.
