Abstract:
Objective To analyze pathologic features, therapeutic strategies and prognosis of patients with metastatic solid pseudopapillary tumor of the pancreas (m-SPTP). Methods Twenty five patients with m-SPTP undergoing radical resection between June 1985 and Dec 2005 were retrospectively analyzed. Kaplan-Meier analysis was used to screen out risk factors of the prognosis of m-SPTP patients.Results Twenty-three postoperative patients were followed up until Dec 2007. The follow-up rate was 92% and the median follow up time was 78 months. The 5-year overall survival rate was 82%. Kaplan-Meier analysis showed that five variables including age, tumor size, pathologic features, number of metastatic lesions and lymphatic metastasis were related to overall survival. Conclusions Solid pseudopapillary tumor of the pancreas is low-grade malignant potential with a favorable prognosis, but not for the m-SPTP.Patients of ≥40 years old, tumor size (≥6 cm), pathologic features (including presence of areas with diffuse growth pattern and tumor necrosis), multiple metastatic lesions and lymphatic metastasis have poor prognosis.
