Race Influences Stage-specific Survival in XXXX .

@entity1 @entity356 @entity1349 @entity66
UNASSIGNED: @entity356 studies show improved survival for Asians but have not reported stage-specific @entity1349 ( @entity1349 ) or @entity66 ( @entity66 ) by race. The Surveillance, Epidemiology and End Results database was queried for cases of @entity356 between 1998 and 2008. We evaluated @entity1349 and @entity66 by race and stage. Number of assessed lymph nodes was compared among surgical @entity1 . Of 49,058 @entity1 with complete staging data, 35,300 were white, 7709 were Asian, and 6049 were black. Asians had significantly better @entity1349 for all stages (P < 0.001) and significantly better @entity66 for Stages I (P < 0.0001) and II (P = 0.0006). As compared with blacks, whites had significantly better @entity66 for Stages I (P < 0.0001), II (P = 0.0055), III (P = 0.0165), and IV (P < 0.0001). Among the 28,133 (57%) surgical @entity1 , average number of evaluated lymph nodes was highest for Asians (P < 0.0001). Among surgical @entity1 with 15 or more nodes evaluated, @entity66 was worse in blacks with Stage I disease (P < 0.05). Blacks with @entity356 have a worse @entity66 , which disappears when surgical treatment includes adequate lymphadenectomy. Race-associated survival differences for @entity356 might simply reflect variations in surgical staging techniques and socioeconomic factors.
