2003 JUN 5 - (NewsRx.com & NewsRx.net) -- Researchers say there appears to be evidence of racial differences in treatment of breast cancer among women under 50, since survival rates by stage-at-diagnosis for younger black women are lower than for white women.
In the study, published in the June 1, 2003, issue of Cancer, the authors observed that 6-year survival rates were significantly lower for black women <50 years old for identical stage and estrogen receptor (ER) status cancers. No significant racial differences in the stage-specific survival rates were found for women>65 years, suggesting that Medicare may help alleviate racial disparities in cancer treatment. Black women of all ages were diagnosed at later stages of breast cancer compared to white women, indicating the need for more early diagnosis for black women of all ages.
The difference in survival among black women with breast cancer and later stage at diagnosis implicate racial differences in access to healthcare resources. The authors concluded, "The structural barriers may be overcome by offering health insurance" to provide equal access to treatment "and by providing information to physicians and patients" about effective screening and treatment options.
Racial differences in breast cancer survival are often studied but not well understood. Repeated analyses have shown that black women are diagnosed at a more advanced stage than white women, resulting in lower long-term survival rates. Some studies point to race being an independent prognostic factor even after adjustment for clinical and socioeconomic factors. However, disparities in screening and treatment may be a more significant contributing factor.
Previous studies have shown that black women were less likely to receive screening mammograms and less likely to receive the same treatment as white women, such as surgery or radiation, for the same stage and ER-type cancer. When racial cancer management differences are addressed, clinical trials show equal stage-specific survival rates for black and white women with breast cancer.
To identify racial differences in treatment, Chu et al. examined differences in black and white stage-specific survival rates, which are affected by postdiagnosis factors such as treatment, and their relationship with ER status, which ...
