Abstract

Background: Solid pseudopapillary neoplasms (SPPNs) comprise the majority of pediatric pancreatic neoplasms. We queried the National Cancer Database to compare pediatric and adult patients with SSPNs to examine differences in demographics, tumor characteristics, treatment, and overall survival. We aimed to determine if survival differences existed between adult and pediatric patients with SPPN. Methods: The National Cancer Database (2004-2014) was reviewed, and patients were stratified by age at diagnosis: pediatric (≤21 y) and adult (≥22 y). Demographics, comorbidities, tumor characteristics, diagnostic periods, treatments, and survival rates were compared using pooled variance t-tests and chi-square, followed by multivariate Cox proportional hazard model (α = 0.05). Log-rank test was used to compare survival. Results: A total of 468 patients were analyzed and categorized according to age group. Four hundred and fourteen patients were included in the survival analysis. The pediatric patients were primarily female, Caucasian, had no comorbidities, and presented with stage I disease. Race/ethnicity, gender, socioeconomic status, comorbidities, and disease stage at presentation were similar between the groups. There was no difference in time to initiation of therapy or to surgical intervention. No significant difference was found in type of surgical resection, chemotherapy, or radiotherapy utilization. Despite the similarities between groups, comparison of overall survival demonstrated improved survival of pediatric SPPN compared with adult SPPN in every pathologic stage. Conclusions: These results suggest that pediatric and adult SPPNs are similar with regards to demographics, tumor characteristics, and treatment modalities. However, survival was better in children with SPPNs, which may be due to differences in tumor biology and may serve for risk stratification of prognosis.
