Poorer Women More Likely to Die From Breast Cancer

 Less-affluent women now face a greater risk of dying from breast cancer than wealthier patients, a new American Cancer Society report finds.
The trend represents a reversal of a previous trend, in which women with greater means had been at a greater risk for dying from the disease.
"In general, progress in reducing breast cancer death rates is being seen across races/ethnicities, socioeconomic status and across the U.S.," said Dr. Otis Brawley, chief medical officer for the American Cancer Society, in a society news release. "However, not all women have benefited equally."
"Poor women," he noted, "are now at greater risk for breast cancer death because of less access to screening and better treatments. This continued disparity is impeding real progress against breast cancer, and will require renewed efforts to ensure that all women have access to high-quality prevention, detection and treatment services."
The report, "Breast Cancer Statistics, 2011" is in the current issue of CA: A Cancer Journal for Clinicians.
More than 230,000 women will face a breast cancer diagnosis this year, and nearly 40,000 will die. The disease is the most common cancer among American women, after skin cancer, according to the report.
However, the overall U.S. breast cancer death rate has been on a steady decline for more than two decades. For women under 50, fatalities fell roughly 3% per year since 1990. For patients over 50, the drop was about 2% per year.
Death rates have gone down in 36 states and the District of Columbia between 1998 and 2007.
Yet the new report finds that death rates have not fallen at the same pace across all racial and socioeconomic lines, with the remaining 14 states experiencing little to no drop-off.
Until the early 1990s, women living in more-affluent areas had a higher death rate than those in poorer neighborhoods. But in the ensuing years, a relatively slow drop in death rates among poorer women has reversed the situation, so that today it is the less- affluent who are burdened with the highest death risk.
Dr. Rachel A. Freedman, a Boston-based medical oncologist with the Dana Farber Cancer Institute, said that less-affluent breast cancer patients face a "perfect storm" when it comes to mortality risk.
"Women from lower economic status have less access to resources, have suboptimal insurance coverage, may receive substandard care and often present with more advanced cancer at diagnosis," she noted. "So it's not surprising that they often face a substandard outcome."
"So it's a really complicated situation ... and that will mean that complicated interventions will be required to tackle this problem," she added. "But unfortunately, I don't see anything happening right now that's going to turn this around in the near term."

Death Rate Higher in Minorities With Acute Leukemia


Death Rate Higher in Minorities With Acute Leukemia

A new study finds that blacks and Hispanics are less likely to develop acute leukemia than whites. But if they do become ill, they're much more likely to die.
"We don't know the reason for the disparity, but now that we know it exists we can investigate why it occurs," said study lead researcher Dr. Manali I. Patel, postdoctoral fellow in hematology/oncology at the Stanford Cancer Institute in Stanford, Calif., in a statement provided by the American Association for Cancer Research. "Like all disparities in cancer, there could be any combination of influences; however, we believe that socioeconomic factors and access to care may be playing an important role."
After studying medical records of nearly 41,000 patients with acute leukemia between 1998 and 2008, the researchers found that blacks had a 17% higher risk of dying of acute leukemia than whites, and Hispanics had a 12% higher risk.
Acute leukemia comes in two forms, acute lymphoblastic leukemia and acute myelogenous leukemia. One of them -- the former -- revealed a much higher difference in mortality. Blacks and Hispanics with acute lymphoblastic leukemia faced about a 45% and 46% higher risk, respectively, of dying than whites. For acute myelogenous leukemia, the added risk was 12% for blacks and 6% for Hispanics.
"These data tell us that the disparity in overall survival in acute leukemia is driven by higher death rates in [acute lymphoblastic leukemia]," Patel said.
Leukemia isn't the only cancer which minorities have a lower risk of getting but a higher risk of dying from, researchers said. "This paradox is seen in other solid tumors, such as breast cancer. It occurs less frequently in black women, but mortality rates, stage for stage, are higher," Patel said. "Now that we have taken the crucial first step to document this disparity in acute leukemia, we need to understand the factors behind it so we can address and correct it."
The study was scheduled to be released at the American Association for Cancer Research Conference on The Science of Cancer Health Disparities in Washington D.C.
Research presented at a medical meeting should be considered preliminary until published in a peer-reviewd journal.
