Fig 6. Kaplan-Meier Curves for Patients with PNET in the Intra-abdominal and Retroperitoneal Regions.

All patients (n = 18) (A). The 18 patients were divided into three groups based on different surgical methods: radical resection (n = 5), partial resection (n = 6) or biopsy only (n = 7) (B). Multiple comparisons between the three groups showed no significant differences (p>0.10).
