Introduction: Solid pseudopapillary tumors of pancreas (SPTP) is an indolent rare tumor with malignant potential. The prediction of malignancy is an enigma. The aim of this study is to explore the relationship between operative measurements and malignancy prognosis of SPTP patients.
Methods: A cohort of consecutive 102 patients were enrolled in this study. Preoperative measurements and clinical outcomes were analyzed.
Results: Eighteen patients (17.6%) were confirmed as malignant. The malignant SPTP of the optimal cut-off value was 47.9 (p=0.012) for prognostic nutritional index (PNI). The value of PNI≤ 47.9 and incomplete capsule were significantly correlated with malignancy. Univariate analysis showed that the PNI≤ 47.9 (p=0.013) and incomplete capsule (p< 0.001) were predictors of disease-specific survival (DSS). Multivariate analysis identified the PNI≤ 47.9 (p=0.036) and incomplete capsule (p=0.023) as the independent prognostic factors of DSS. The new score of 0,1,2 based on PNI and capsule presence stratified the patients into 3 groups. The patients with low PNI and incomplete capsule achieved the worst prognosis.
Conclusion: The combination test of operative PNI and capsule presence would be a reliable indicator of the aggressive natural history of SPTP.
