Odds Good for Older Women With DCIS, Early Breast Cancer

By Charles Bankhead, Staff Writer, MedPage Today

A diagnosis of ductal carcinoma in-situ (DCIS) or stage I breast cancer does not reduce survival odds for women older than 67, but diagnosis of a higher-stage malignancy does, an NIH database analysis showed.

Women with DCIS or stage I breast cancer had mortality hazards of 0.9 to 1.0 compared with age-matched women who did not have breast cancer, according to Mara A. Schonberg, MD, of Beth Israel Deaconess Medical Center in Boston, and colleagues.

However, the mortality risk increased by 50% compared with controls with a diagnosis of stage II or higher breast cancer, they reported online in the Journal of Clinical Oncology.

"More women age 67 years and older diagnosed with DCIS or stage I breast cancer and women age ≥80 years diagnosed with stage II disease die of cardiovascular disease than breast cancer," Schonberg and colleagues wrote in the discussion of their findings.
