THURSDAY, June 27 (HealthDay News) -- Breast cancer patients in rural areas of the United States are less likely than those in cities to receive recommended radiation therapy after having a lumpectomy, a new study finds.
Lumpectomy is a breast-sparing surgery that removes only tumors and surrounding tissue.
"The lumpectomy findings are worrisome because lack of follow-up radiation therapy could lead to recurrence, another surgery, and another time period of concern for the woman and her family," Elizabeth Habermann, associate scientific director of surgical outcomes at the Mayo Clinic Center for the Science of Health Care Delivery, said in a Mayo news release.
The analysis of data from nearly 350,000 California breast cancer patients treated between 1996 and 2008 revealed other differences in diagnosis and treatment between rural and urban patients, the researchers said.
Rural women were less likely to have their estrogen-receptor status tested and their tumor graded, which are two important parts of the diagnostic work-up for breast cancer. Rural women were also more likely to choose mastectomy (complete removal of the breast) rather than lumpectomy.
The findings were presented at the AcademyHealth annual research meeting, held June 23-25 in Baltimore.
"These study results are concerning," Habermann said. "All women should receive guideline-recommended cancer care, regardless of where they live."
She and her colleagues said further research is needed to determine the reasons for the differences between rural and urban breast cancer patients, so that action can be taken to correct them.
Despite the deviation from recommended treatment, no significant difference in death rates was noted between rural and urban breast cancer patients.
The data and conclusions of research presented at meetings should be considered preliminary until published in a peer-reviewed medical journal.
