CNN —A drug used in people in the early stage of the most common kind of breast cancer – HR+/HER2- breast cancer – significantly reduced the risk of the cancer returning after treatment, according to a new study. HR+/HER2- breast cancer has tested positive for progesterone and estrogen receptors and negative for HER2. Endocrine therapy generally works well, but for patients with HR+ or HER- breast cancer, there’s still a 10% to 40% chance that the cancer will come back, some studies show. The new trial found that when Kisqali is added to endocrine therapy, it reduces the risk of recurrence by 25% across a broad population of patients with early breast cancer. About 90% of patients who have breast cancer are diagnosed in the early stages.
