AIM: To present our experiences in studying the clinicopathological features of small nonfunctioning pancreatic @entity5 (NF-pNETs). METHODS: The subjects included 9 @entity1 with NF-pNETs who underwent pancreatectomy between April 1996 and September 2012. The surgical procedure, histopathological findings, and prognosis were assessed. RESULTS: All @entity5 were incidentally detected by computed tomography. The median diameter was 10 mm (5-32 mm). One @entity1 was diagnosed with @entity280 , and the others were sporadic cases. For the histopathological findings, 7 @entity1 were G1; 1 @entity1 was G2; and 1 @entity1 , whose @entity5 was 22 mm, had @entity3270 ( @entity3270 ). One @entity1 who had a @entity5 that was 32 mm had direct invasion to a regional lymph node and 1 @entity1 with @entity3270 , had regional lymph node @entity3 . Six of the 7 @entity1 with sporadic NF-pNETs, excluding the @entity1 with @entity3270 , had @entity5 that were smaller than 10 mm. @entity5 smaller than 10 mm showed no @entity5 and lacked lymph node @entity3 . CONCLUSION: Sporadic NF-pNETs smaller than 10 mm tend to have less malignant potential. These findings suggest that lymphadenectomy may be omitted for small NF-pNETs after further investigation.
