To date, there has been little research done on the impact of diabetes, and in particular, the impact of poor blood sugar control on advanced breast cancer outcomes. Current studies have mainly focused on patients with early rather than late stage cancer.
Researchers studied 488 patients with metastatic breast cancer. Half have diabetes. The study found that overall 5-year survival was similar between the two groups.
However, among people who survived at least 8 years after being diagnosed with cancer, survival was better for those without diabetes than those with diabetes (87% versus 67% at 10). five).
In these longer survivors, survival was also better in those with good glycemic control than in those with poor glycemic control (83% vs 63% at 10 years).
Linked to diabetes and worse outcomes in breast cancer survivors
“These findings are important because they suggest that diabetes treatment and glycemic goals should be tailored specifically for patients even with advanced cancer based on expected prognosis,” she added. theirs.
“It remains uncertain whether controlling blood sugar levels in patients with diabetes and breast cancer can improve cancer outcomes,” says Cheung.
“In some cases, blood sugar control may not be vigorously pursued by physicians, especially in advanced cases of cancer, and strict diabetes control may be overlooked.” The link between poor blood sugar control and worse cancer outcomes could change the way doctors treat diabetes in patients with late-stage breast cancer.”
