Fig. 3From: Risk factors associated with the progression and metastases of hindgut neuroendocrine tumors: a retrospective studyDifferences in the maximum tumor between tumors with and without lymph node metastasis. The maximum tumor diameter in patients with lymph node metastasis was significantly larger compared with that in those without lymph node invasion. The maximum tumor diameter was a significant risk factor for lymph node invasion in hindgut neuroendocrine tumorsBack to article page
