Cancer patient survival among ethnic groups in the United States

Abstract

Data from the Surveillance, Epidemiology and End Results Program of the National Cancer Institute were used in the evaluation of cancer patient survival experience for 8 racial-ethnic groups in the U.S. population--Anglos, Hispanics, blacks, American Indians, Chinese, Japanese, Filipinos, and Hawaiians. This report contains an actuarial (life table) survival analysis on 402,752 patients with first primary cancer diagnosed in 1973-79 and followed through December 31, 1981. Relative and observed survival rates are shown for each sex separately by primary site. Survival rates for females exceeded those for males for each primary site except for gallbladder and urinary bladder. The primary site having the highest survival rate among each group studied was the thyroid gland with a 5-year relative rate of 91% for all races combined. Rates were uniformly low among each group for cancers of the esophagus, liver, and pancreas. Survival rates for Hispanics were almost identical to those for Anglos; the largest differences were found for bladder (73% for Anglos vs. 64% for Hispanics), Hodgkin's disease (70% for Anglos vs. 61% for Hispanics), and ovary (35% for Anglos vs. 42% for Hispanics). For many primary sites Japanese experienced the highest survival rates and American Indians the lowest. In comparison to Anglos, Japanese had higher survival for cancers of the stomach, colon, prostate gland, and breast. The higher survival for stomach and breast cancers persisted even when controlling for age of patient and stage of disease at diagnosis. Survival rates for blacks were much lower than those for whites for cancers of the corpus uteri and urinary bladder. Survival rates for Chinese and Hawaiians were roughly comparable to those for Anglos, whereas survival rates for Filipinos tended to be similar to those for blacks.
