Contrary to previous studies, African-American women with early-stage breast cancer who have surgery to remove the cancer (lumpectomy) followed by radiation therapy have a higher chance of their cancer coming back in the breast and lymph nodes 10 years after diagnosis, compared to their Caucasian counterparts, according to the largest study of its kind, presented at a scientific session October.
The study also shows that early-stage breast cancer patients who are African-American women who are diagnosed with the disease at a younger age have a higher disease stage at diagnosis (larger tumors and cancer that has spread to the lymph nodes) and more aggressive tumors than Caucasian women who undergo similar treatment.
The cohort study involved 2,382 patients over a 30-year period who underwent a lumpectomy and radiation therapy for early-stage breast cancer. Researchers wanted to find out if there were differences in the outcomes between AfricanAmerican patients and Caucasians. Findings showed that 10 years after treatment with lumpectomy and radiation, 17 percent of African-American women had their breast cancer recur compared with 13 percent of Causcasian patients.
