Survival was examined by ethnic group for 31,465 incident cancer cases diagnosed from 1969 through 1982 in Hispanic and non-Hispanic whites residing in New Mexico and in American Indians residing in New Mexico and Arizona. In comparison with the 1- and 5-year survival rates following the diagnosis of cancer for non-Hispanic whites, those for American Indians were generally poorer and, to a lesser extent, those for Hispanics were also poorer. The American Indian and Hispanic patients tended to have more advanced disease at the time of diagnosis, although this pattern was not consistent across all sites. For many primary cancer sites, American Indian patients were less likely to receive treatment for their cancer than were non-Hispanic whites. Hispanics were also less likely to be treated for cancers of some sites, although the differences were not as large as for American Indians. However, after adjustment for stage and treatment, American Indians demonstrated significantly poorer survival than non-Hispanic whites for cancers of many sites. After adjustment for stage and treatment, survival in Hispanics was generally comparable to that in non-Hispanic whites.
对1969年至1982年期间在新墨西哥州居住的西班牙裔和非西班牙裔白人以及在新墨西哥州和亚利桑那州居住的美国印第安人中确诊的31465例新发癌症病例，按种族群体对生存率进行了研究。与非西班牙裔白人癌症诊断后的1年和5年生存率相比，美国印第安人的生存率总体较差，西班牙裔的生存率在较小程度上也较差。美国印第安人和西班牙裔患者在诊断时往往病情更严重，尽管这种模式在所有部位并不一致。对于许多原发性癌症部位，美国印第安患者比非西班牙裔白人接受癌症治疗的可能性更小。西班牙裔在某些部位患癌症时接受治疗的可能性也较小，尽管差异不如美国印第安人大。然而，在对分期和治疗进行调整后，美国印第安人在许多部位癌症的生存率明显低于非西班牙裔白人。在对分期和治疗进行调整后，西班牙裔的生存率总体上与非西班牙裔白人相当。
