Prediction of Recurrence Risk in Solid Pseudopapillary Neoplasm of the Pancreas: Single-Institution Experience

Abstract: Background: Solid pseudopapillary neoplasm (SPN) of the pancreas is a low-grade malignant neoplasm with unpredictable behavior. Factors associated with recurrence were not conclusively identified. The aim of this study is to define the clinicopathological criteria for recurrence risk prediction in SPNs based on the most recent scientific evidence and to present our experience with SPNs.Methods: A retrospective review of patients with SPNs operated on in our institution from June 2012 to June 2018 was completed… Show more

“…According to the current data, 3% of individuals with SPN experience recurrence after resection; most of them occurred within 5 years. 16 In this case, the poor prognostic factors were the residual lymph node of the SMA root area and the large tumor size.…”

“…The precise recurrence rate after complete tumor resection is not well established, but it may be higher in patients who undergo tumor enucleation or incomplete excision, both of which should be avoided [ 3 ]. As the mean time to recurrence was found to be approximately four years, patients treated for SPN should be monitored for at least five years [ 28 ]. Large tumors, exceeding 3.0 cm, typically exhibit rounded shapes, are well-circumscribed, and are encased by a fibrous pseudocapsule, distinctly separated from the pancreatic tissue.…”

“…In the literature, the rate of malignancy is about 10-15% and is highly associated with tumor size larger than 5 cm, lymphovascular invasion, pancreatic parenchymal invasion, a Ki-67 index greater than 3%, or the presence of metastasis at presentation as described in the WHO malignancy criteria [ 6 - 8 , 19 - 22 ]. Both males and females tend to have a low malignancy risk.…”
