Background: Pancreatic serous cystic tumors are considered to have a benign biological and clinical course with only few malignant cases.
Methods: We retrospectively analyzed data from 26 patients affected by serous cystic tumors consecutively observed in our Pancreas Unit. We explored the different clinical pictures in operated and nonoperated patients.
Results: Eighteen of the 26 patients were female (69%), median age at diagnosis was 61.5 years and 20 patients (77%) underwent surgery. The median diameter of the tumors was greater in patients who underwent surgery than in those who did not (5.5 versus 2.3 cm, p < 0.001). Major pancreatic resections were carried out in 15 of the 20 operated patients (75%). Postoperative morbidity and mortality were 20 and 5%, respectively. During follow-up, there was no observed development of malignancy or any significant increase in the diameter of the lesion among nontreated patients.
Conclusions: In asymptomatic patients with a clear imaging diagnosis of serous cystic tumor a wait and see management should be recommended, with a careful follow-up. Surgery should be suggested in symptomatic patients or when the preoperative diagnosis is doubtful.
