摘要
Since solid pseudopapillary tumor of the pancreas(SP-TP) was officially classified by the World Health Org-anization in 1996,SPTP has recently received special attention in the literature.Studies have shown that SPTP is a heterogeneous tumor,with a small percentage of patients harboring aggressive behaviors.However,cri-teria for malignancy grade in SPTP have not been well established.The prognosis of SPTP is generally good,with cases having a chance for long-term survival even with recurrence and/or metastasis after surgical resection.The current American Joint Committee on Cancer/Union for International Cancer Control tumor,node,metastasis staging system is not specific to SPTP.The lack of a pre-dictive staging classification that accurately describes the heterogeneity of this disease hinders meaningful research into optimal individualized therapy.Here we summarize and discuss the associated factors proposed for appraisal of the malignant potential and adverse outcome of SPTP.
