Survival differences in nasopharyngeal carcinoma among racial and ethnic minority groups in the United States: A retrospective cohort study.
The literature on nasopharyngeal carcinoma survival in the United States has focused mostly on Whites or Asians and not much is known about survivorship in other minority racial and ethnic groups. We aimed to determine the disease-specific survival rate and prognostic factors for nasopharyngeal carcinoma survival across the minority United States population.
A retrospective cohort study.
The Surveillance, Epidemiology and End Results (SEER) 13 database from 1992 to 2014 was queried for adult cases of nasopharyngeal carcinoma (n = 2549).
Eligible cases were Blacks, Hispanics, Asians/Pacific Islanders, American Indians/Alaska Natives; White patients were excluded.
A multivariable competing risk survival analysis yielded hazard ratios (HR) for competing mortality and was used to identify independent prognostic factors for survival.
Non-Hispanic American Indians/Alaska Natives consistently had the worst cause-specific survival of any group and that non-Hispanic Asians/Pacific Islanders consistently had the best survival (P < 0.001). Even after adjusting for other poor prognostic factors in the study, including older age, keratinising histology, and lack of radiation treatment, non-Hispanic American Indians/Alaska Natives had more than double hazards of death from nasopharyngeal cancer compared with non-Hispanic Asians/Pacific Islanders (aHR = 2.63, 95% CI 1.67, 4.13).
There are disparities in nasopharyngeal carcinoma survival among racial and ethnic minority groups in the United States, with American Indians/Alaskan Natives faring worst. It is critical that future research focuses on nasopharyngeal carcinoma among this population to improve survivorship and mitigate cancer-related health disparities.

Increased risk for colorectal cancer under age 50 in racial and ethnic minorities living in the United States.
Colorectal cancer (CRC) is the second most common cause of cancer death in USA. We analyzed CRC disparities in African Americans, Hispanics, Asians/Pacific Islanders, and American Indians/Alaska Natives compared to non-Hispanic Whites. Current guidelines recommend screening for CRC beginning at age 50. Using SEER (Surveillance, Epidemiology, and End Results) database 1973-2009 and North American Association of Central Cancer Registries (NAACCR) 1995-2009 dataset, we performed frequency and rate analysis on colorectal cancer demographics and incidence based on race/ethnicity. We also used the SEER database to analyze stage, grade, and survival based on race/ethnicity. Utilizing SEER database, the median age of CRC diagnosis is significantly less in Hispanics (66 years), Asians/Pacific Islanders (68 years), American Indians/Alaska Natives (64 years), and African Americans (64 years) compared to non-Hispanic whites (72 years). Twelve percent of Asians/Pacific Islanders, 15.4% Hispanics, 16.5% American Indians/Alaska Natives, and 11.9% African Americans with CRC are diagnosed at age <50 years compared to only 6.7% in non-Hispanic Whites (P < 0.0001). Minority groups have more advanced stages at diagnosis compared to non-Hispanic Whites. Trend analysis showed age-adjusted incidence rates of CRC diagnosed under the age of 50 years have significantly increased in all racial and ethnic groups but are stable in African Americans. These results were confirmed through analysis of NAACCR 1995-2009 dataset covering nearly the entire USA. A significantly higher proportion of minority groups in USA with CRC are diagnosed before age 50 compared to non-Hispanic Whites, documenting that these minority groups are at higher risk for early CRC. Further studies are needed to identify the causes and risk factors responsible for young onset CRC among minority groups and to develop intervention strategies including earlier CRC screening, among others.

Changes in midlife death rates across racial and ethnic groups in the United States: systematic analysis of vital statistics.
To systematically compare midlife mortality patterns in the United States across racial and ethnic groups during 1999-2016, documenting causes of death and their relative contribution to excess deaths.
Trend analysis of US vital statistics among racial and ethnic groups.
United States, 1999-2016.
US adults aged 25-64 years (midlife).
Absolute changes in mortality measured as average year-to-year change during 1999-2016 and 2012-16; excess deaths attributable to increasing mortality; and relative changes in mortality measured as relative difference between mortality in 1999 versus 2016 and the nadir year versus 2016, and the slope of modeled mortality trends for 1999-2016 and for intervals between joinpoints.
During 1999-2016, all cause mortality in midlife increased not only among non-Hispanic (NH) whites but also among NH American Indians and Alaskan Natives. Although all cause mortality initially decreased among NH blacks, Hispanics, and NH Asians and Pacific Islanders, this trend ended in 2009-11. Drug overdoses were the leading cause of increased mortality in midlife in each population, but mortality also increased for alcohol related conditions, suicides, and organ diseases involving multiple body systems. Although midlife mortality among NH whites increased across a multitude of conditions, a similar trend affected non-white populations. Absolute (year-to-year) increases in midlife mortality among non-white populationsoften matched or exceeded those of NH whites, especially in 2012-16, when the rate of increase intensified for many causes of death. During 1999-2016, NH American Indians and Alaskan Natives experienced large increases in midlife mortality from 12 causes, not only drug overdoses (411.4%) but also hypertensive diseases (269.3%), liver cancer (115.1%), viral hepatitis (112.1%), and diseases of the nervous system (99.8%). NH blacks experienced increased midlife mortality from 17 causes, including drug overdoses (149.6%), homicides (21.4%), hypertensive diseases (15.5%), obesity (120.7%), and liver cancer (49.5%). NH blacks also experienced retrogression: after a period of stable or declining midlife mortality early in 1999-2016, death rates increased for alcohol related liver disease, chronic lower respiratory tract disease, suicides, diabetes, and pancreatic cancer. Among Hispanics, midlife mortality increased across 12 causes, including drug overdoses (80.0%), hypertensive diseases (40.6%), liver cancer (41.8%), suicides (21.9%), obesity (106.6%), and metabolic disorders (60.0%). Retrogression also occurred in this population; after a period of declining mortality, death rates increased for alcohol related liver disease, mental and behavioral disorders involving psychoactive substances, and homicides. NH Asians and Pacific Islanders were least affected by this trend but also experienced increases in midlife mortality from drug overdoses (300.6%), alcohol related liver disease (62.9%), hypertensive diseases (28.3%), and brain cancer (56.6%). The suicide rate in this group increased by 29.7% after 2001. The relative increase in US midlife mortality differed by sex and geography. For example, the relative increase in fatal drug overdoses was greater among women than among men. Although the relative increase in midlife mortality was generally greater in non-metropolitan (ie, rural) areas, the relative increase in drug overdoses among NH whites and Hispanics was greatest in suburban fringe areas of large cities, and among NH blacks was greatest in small cities.
Mortality in midlife in the US has increased across racial-ethnic populations for a variety of conditions, especially in recent years, offsetting years of progress in lowering mortality rates. This reversal carries added consequences for racial groups with high baseline mortality rates, such as for NH blacks and NH American Indians and Alaskan Natives. That death rates are increasing throughout the US population for dozens of conditions signals a systemic cause and warrants prompt action by policy makers to tackle the factors responsible for declining health in the US.
