    Abstract:
    BACKGROUND/OBJECTIVES: We evaluated the diagnoses and surgical management of solid pseudopapillary tumors of the pancreas (SPTP) in a single center setting. METHODS: Demographic details, clinical presentations, imaging features, surgical strategies, and pathological findings of 97 consecutive patients who underwent surgery for pathologically confirmed SPTP between 2008 and 2016 were analyzed retrospectively. RESULTS: A total of 97 patients with SPTP accounted for 2.15% of total pancreatic surgeries (N = 4508). The mean age at diagnosis was 31.6 ± 13.92 years (range: 7-83 years), and males:females were 85:12. Chief complaints were abdominal pain or discomfort (n = 50). The mean transverse tumor diameter was 53.2 ± 2.76 mm (range: 14-170 mm). Tumors were localized to the pancreatic head (38.1%; 37/97), neck (12.4%; 12/97), body and tail (49.5%; 48/97). There were no significant differences in age of onset, presenting symptoms, and sites between males and females. A significant difference was found in the maximum diameter of SPTP across different age groups. Partial pancreatectomy was performed for patient with tumor ≥ 5 cm, and enucleation was performed when tumor was smaller than 5 cm. Pancreatic fistula was the main complication. Immunohistochemical markers for endocrine, exocrine and epithelial factors were used for a final diagnosis. During a median follow-up of 54 months (range: 7-121 months), 84 patients were alive without evidence of recurrence, and 13 patients were lost to follow-up. CONCLUSION: SPTP surgical resection is a safe procedure with low morbidity and mortality, which is also effective even in the presence of invasiveness and metastases. Accurate initial diagnoses and follow up are essential.
