376 Background: The prognostic value of pathologic variables is not consistent for gastroenteropancreatic neuroendocrine tumors (GEP-NETs). We previously demonstrated a limited prognostic role of lymph node (LN) positivity in small bowel NETs (SBNET) compared to pancreatic NETs (panNET). Although minority race is often associated with worse cancer outcomes, the interaction of race with pathologic and oncologic outcomes of pts with GEP-NETS is not known. Methods: Pts with GEP-NETs who underwent curative intent resection at eight institutions of the US NET Study Group from 2000-16 were included. Given few pts of other races, only Black and White race pts were analyzed. Results: Of 2,182 pts, 1,143 met inclusion criteria. Median age was 58 yrs, median follow up was 3 yrs, 48% were male, 14% (n = 157) were Black, and 86% (n = 986) were White. Black pts were more likely uninsured (7 vs 2%, p = 0.005), had symptomatic bleeding (13 vs 7%, p = 0.006), required emergency surgery (7 vs 3%, p = 0.003), and had LN positive disease (47 vs 36%, p = 0.016). Despite this, Black pts had improved 5 yr recurrence free survival (RFS) compared to White pts (90 vs 80%, p = 0.008). The quality of care received was comparable between both groups, demonstrated by similar LN yield at surgery, neg margin resection rate, post-op complications, and need for reoperation or readmission (all p > 0.05). Black pts were more likely to have SBNET (22 vs 13%) and less likely to have panNET (43 vs 68%) compared to White pts (p < 0.001). Consistent with prior data, pts with LN pos panNET had decreased 5yr RFS (67 vs 83%, p = 0.001); however, for SBNET, LN involvement was not prognostic (77 vs 96%, p = 0.08). The prognostic value of LN pos disease was similar between Black and White pts in both SBNET (p = 0.34) and panNET (p = 0.95). Conclusions: Black pts with GEP-NET present with more advanced disease, including higher LN positivity. Despite this, Black pts have improved RFS compared to White pts. Although there may be delays in seeking or reaching care, Black pts received similar quality of care compared to White pts. The improved RFS seen in Black pts may be attributed to the epidemiologic differences in the site of presentation of GEP-NETs and variable prognostic value of LN pos disease.
