Survival analysis for patients with resected pancreatic neuroendocrine neoplasms with or without lymph node metastasis. a Overall survival showed PNEN patients without lymph node metastasis had a more favorable prognosis than those with positive lymph node metastasis. b Recurrence-free survival also showed PNEN patients without lymph node metastasis had more favorable outcomes than those with positive lymph node metastasis.
