A team led by Oluwaseun Ayoade at Yale examined treatment choices and outcomes for patients with breast cancer. Their analysis of the National Cancer Database, which captures about 70% of newly diagnosed US patients, included more than two million people and appears in JAMA Network Open.
About 98% of women received traditional therapies such as surgery, chemotherapy, endocrine therapy, or radiation. Patients treated only with complementary and alternative medicine had a 3.7-fold higher mortality, meaning they were nearly four times more likely to die within five years. Outcomes for the CAM-only group were similar to patients who received no treatment.
Patients who combined CAM and traditional treatments had 1.4 times higher mortality than those who used only traditional care. Further analysis suggested the combined group often skipped radiation and endocrine therapies, which likely reduced survival. The authors urged open discussion between patients and medical teams about all treatments.
