Studies have demonstrated that black and Hispanic women are less likely to receive recommended breast cancer treatments than white women, but few studies have examined whether these differences in the receipt of breast cancer care are affected by patients' socioeconomic status and health insurance.
Rachel Freedman, MD, MPH, of the Dana-Farber Cancer Institute in Boston led a team that examined recommended breast cancer care (including localized therapy, hormone receptor testing, hormonal therapy, and chemotherapy) received by a large national sample of women with breast cancer. The researchers assessed whether insurance and socioeconomic factors were associated with any observed racial/ethnic differences in care.
The study included information from 662,117 white, black, and Hispanic women who were diagnosed with invasive breast cancer from 1998 to 2005 at National Cancer Data Base (NCDB) hospitals. (The NCDB is a registry that collects patient demographics, tumor characteristics, first course of treatment, and outcomes for cancer patients treated at U.S. hospitals.) Most women were white (86 percent), 10 percent were black, and 4 percent were Hispanic. Most had private insurance (51 percent) or Medicare (41 percent).
Compared with white women, black women had 0.91 times lower odds of receiving recommended local therapy, 0.90 times lower odds of receiving hormonal therapy, and 0.87 times lower odds of receiving chemotherapy. Hispanic women were also less likely than white women to receive hormonal therapy. Hormone receptor testing did not differ by race/ethnicity. These modest racial disparities persisted even after accounting for insurance and socioeconomic status.
Despite efforts to eliminate disparities in cancer care in recent years, this study suggests that modest racial differences in the receipt of recommended breast cancer care still persist even after taking patients' insurance and socioeconomic status into account. "Although health insurance expansion may resolve disparities in treatment by health insurance status, this study suggests that expansion alone is unlikely to have a major impact on disparities in breast cancer care among black women," said Dr. Freedman. She noted that multifaceted efforts are needed to ensure that all women with breast cancer receive effective treatments.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
