Hyperglycemia, symptoms, and symptom clusters in colorectal cancer survivors with type 2 diabetes.

These findings indicate that CRCS with diabetes and hyperglycemia had more symptoms and two distinct symptom clusters compared to those with no hyperglycemia. Prospective research studies are needed to examine the role of hyperglycemia in symptoms among CRCS with diabetes. Understanding hyperglycemia's influence is important as it is a modifiable risk factor towards which prevention and intervention can be directed, potentially mitigating symptoms and symptom clusters and improving outcomes for CRCS with diabetes.
