Abstract:
Purpose To explore the correlation between the clinicopathological features and postoperative recurrence or metastasis of solid-pseudopapillary neoplasms of the pancreas (SPN).Method The clinicopathological characteristics of 73 SPNs were summarized,the patients' prognosis were followed up by telephone and then the correlation of clinicopathological characteristics and recurrence or metastasis was analyzed.Results 57 female patients and 16 male patients were included in this study.The age range was 7 to 68 years old with the average of 28 and median age of 27.The mean diameter of the tumors was 6.47 cm (range 0.31～ 14 cm).30 cases of tumors were located in the head of pancreas,9 in the body of pancreas,and 33 in the tail of pancreas.One case was a multiple lesion simultaneously located in the body and the tail.All patients were followed up by telephone for mean time 34.8 months with the range of 12 ～ 99 months.Necrosis,calcification,cholesterol crystal,foamy histiocytes,nuclear atypia,pancreatic parenchymal invasion,and perineural invasion had no statistical significance between non-recurrent/metastatic group and recurrent/metastatic group.However,there was significant difference for extra-pancreatic invasion,angiovascular invasion and Ki-67 proliferation index between non-recurrent/metastatic group and recurrent /metastatic group.Conclusion Extra-pancreatic invasion,angiovascular invasion and Ki-67 proliferation index ≥ 4％ have reference significance for predicting recurrence or metastasis of SPN.
