Eunjung Lee, Lihua Liu, Juanjuan Zhang, ie Hwang, Andre Elizabeth. Kim, Ann S. Hamilton, Anna H. Wu, Dennis Deapen; Belly Malignant tumors Disparity certainly one of Korean Us citizens of the Cyst Services: Testing which have Low-Latina Whites, Japanese People in the us, South Koreans, and you will Japanese. Malignant tumors Epidemiol Biography; twenty-six (4): 587–596.


Background: Belly malignant tumors frequency reveals ample racial-ethnic difference in america, that have Korean Us americans experience definitely the greatest chance. We checked tummy disease frequency manner inside Korean People in america by tumor subsite, histology, and you may stage and you can compared all of them with occurrence costs in racial-cultural communities with the second highest speed (Japanese People in the us) and the reduced rate (non-Hispanic whites; NHWs) together with communities for the South Korea and you may Japan.

Methods: We computed age-modified chance costs because of the racial-cultural teams, sex, and you may tumefaction services, with the 1988–2012 Ca Malignant tumors Registry research. Investigation toward Southern area Korea and The japanese was in fact extracted from new books or other tips.

Results: Anywhere between 1988 and you may 2012 when you look at the California, Korean People in america got throughout the five times better chance than NHWs and you will twice compared to Japanese People in america. Tumefaction features differed by ethnic group and intercourse. The latest occurrence during the Korean People in the us has actually rejected during recent years, for both cardia and you can noncardia sites and also for one another intestinal- and you can diffuse-type histology. Even if Korean People in the us have been identified on an earlier phase than other Californians, this new proportion that have local problem (43%) is far smaller than for the Southern Korea (57%), in which inhabitants-created assessment exists.

Conclusions: Tummy malignant tumors occurrence refused throughout the higher chance ethnic groups. Yet not, the chronic disparity between Korean People in the us and other racial-ethnic communities deserves more tricks for prevention and before diagnosis.

Impact: Studies out-of California Cancer tumors Registry research identified an excellent racial-ethnic subgroup having belly disease difference that make use of directed avoidance and you may testing services. Cancer tumors Epidemiol Bio AACR.


Belly cancer tumors try a frequently deadly problem which have an excellent 5-12 months relative survival rates out of less than 30% and has big affect total well being for the enduring clients (1). Regardless of if tummy cancers occurrence provides diminished significantly over the past multiple many years in america, regarding per one hundred,000 for the 1975 so you can eight.0 for each and every one hundred,100 during the 2012 (1), a substantial disparity in the tummy cancer weight is visible across the racial cultural groups (2–4). Korean American people have undoubtedly this new large tummy malignant tumors chance of the many racial/cultural organizations (2–4), which have a beneficial 4- in order to 5-bend highest incidence than non-Hispanic whites (NHW) within the 2003–2008 (5). In lieu of the significant reduced amount of belly malignant tumors frequency in all almost every other racial/ethnic groups, and additionally Asian Western subgroups instance Chinese, Japanese, and you can Vietnamese which tummy cancers is just one of the greatest 5 cancers, new incidence in the Korean Americans don’t rather (3). Which difference the thing is that new high incidence from inside the Southern area Korea. Southern area Korea comes with the large stomach disease price global (from the ten times of the latest incidence within the U.S. whites), followed closely by Japan (6). Whilst the incidence for the Japan has reduced considerably into the current decades (5, 7), the latest incidence inside the Southern Korea keeps decreased absolutely nothing (8, 9).

Etiology off tummy cancer is recognized to disagree by the cyst subsite (cardia versus. noncardia) and you will histology (intestinal vs. diffuse-type; ref. 10). Cardia gastric malignant tumors was of this obesity and you may reflux situation, whereas noncardia gastric cancer tumors are in the Helicobacter pylori problems (10). Intestinal type is primarily associated with H. pylori illness along with environmental things instance sodium or other losing weight factors, while diffuse particular is assumed becoming related to H. pylori and hereditary products (11–14). These types of subsite- and you can histology-dependent tummy cancers subtypes have shown some other frequency manner and racial difference. Instance, compared to the brand new good-sized reduced total of full belly disease incidence in most ethnic communities in the united states, the latest frequency regarding cardia cancer tumors increased certainly boys within 1970s and you will 1980s (15, 16), additionally the frequency out of diffuse-method of belly cancer improved ranging from 1973 and you may 2000 into the people and you may women, whites and you can nonwhites (fifteen, 17). Incidence pricing of most subtypes was high inside nonwhites compared to whites, with the exception of higher occurrence of cardia subtype during the whites (15, 16). Given the differential etiology and epidemiology round the subtypes and you may competition teams (10), it is important to check the frequency pattern and you can ethnic difference from the cyst subtype and phase within diagnosis to plan efficient reduction measures. Although not, such as for example recommendations has not been revealed erican subgroups.
