BACKGROUND: Sporadic, nonfunctional @entity788 (NF-PNETs) are diagnosed with increasing frequency. We compared the risk of @entity5 growth, @entity3 , and mortality between @entity1 treated versus those treated expectantly. METHOD: A retrospective study of @entity1 seen at our institution with sporadic NF-PNETs, with >= 12 months of follow-up. Kaplan-Meier analysis was performed. RESULTS: Between 1999 and 2014, 35 @entity1 with an incidentally discovered nonfunctional PNET were identified. Twenty underwent resection and 15 were followed with imaging. In the operative group, 8 had NF-PNETs < 2  cm, while 12 had NF-PNETs >=  2  cm. In the nonoperative expectant management by serial imaging group, 10 had NF-PNETs < 2  cm while 5 had NF-PNETs >=  2  cm. Small NF-PNETs (<2  cm) in either the operative or nonoperative groups demonstrated no evidence of progression or @entity3 (median follow-up of 27.8  months). Morbidity in the operative group was 35% with @entity9007 the most common. CONCLUSION: Incidentally discovered NF-PNETs < 2  cm in size can be observed safely with serial imaging.
