New Clues to Why Blacks Fare Worse With Colon Cancer

Robert Preidt
MONDAY, June 23, 2014 (HealthDay News) -- Blacks with colon cancer are about half as likely as whites to get a type of colon cancer that has a better chance of survival, a new study says.

This may be one of the reasons why blacks are more likely to die of colon cancer than whites, the researchers said.

Researchers analyzed information from 503 patients in the North Carolina Colon Cancer Study. They found that 7 percent of blacks and 14 percent of whites had cancer with a genetic marker called microsatellite instability (MSI).

MSI colon cancer is known to be resistant to a chemotherapy drug. However, even without chemotherapy, patients with MSI colon cancer tend to have better outcomes than those without the genetic marker.

Older cancer survivors in rural areas are more likely than those in urban areas to forgo medical and dental care because they can't afford it, a new study finds. Researchers analyzed data from more than 7,800 cancer survivors -- 1,642 from rural areas and 6,162 from urban areas -- who took part in the U.S. National Health Interview Surveys between 2006 and 2010.

Obese women might be able to eliminate their increased risk for postmenopausal breast cancer by taking measures during perimenopause to prevent weight gain and to therapeutically control the metabolic effects of their obesity, according to the results of a preclinical study in an animal model from the University of Colorado Anschutz Health and Wellness Center, published in Cancer Research, a journal of the American Association for Cancer Research. The University of Colorado is home to the University of Colorado Cancer Center. (More...)

Human immunodeficiency virus (HIV) infection contributes substantially to the epidemic of anal cancer in men, but not women in the United States, according to new research from NCI. Anal cancer is rare, with an estimated 6,230 cases in 2012 but incidence rates in the U.S. have risen steadily over the past several decades. This new study documents that among men, half of this increase is explained by cases occurring in those who are HIV-positive. (More...)

Changing the Face of Clinical Trials: "Overall, only about 5 to 10 percent of cancer patients participate in clinical trials. And when it comes to African-American cancer patients, the figures are even lower: 2 to 4 percent. This low participation makes it difficult for researchers to get answers to critical questions: Why are African-Americans more likely to develop certain cancers than other racial and ethnic groups and have higher death rates for some types of the disease? Is it lifestyle? Genetics? Treatment response? Access to health care? No one yet knows. But researchers believe that increasing the number of African-Americans in cancer trials will help them find out. So that can happen, more efforts are under way to identify the reasons that so few African-American cancer patients join clinical trials?and to implement programs that can put them on the clinical trials track."

Vanderbilt study finds diverse genetic alterations in triple-negative breast cancers: Most triple-negative breast cancer patients who were treated with chemotherapy to shrink the tumor prior to surgery still had multiple genetic mutations in their tumor cells, according to a study by Vanderbilt-Ingram Cancer Center (VICC) investigators. Finding multiple mutations instead of just one primary mutation that can be targeted for therapy sheds more light on the challenges of treating triple-negative breast cancer. (More...)
