Objective:

To evaluate the impact of breast cancer treatment on diabetes self-care and management, highlighting its significance for patient outcomes.

Key Findings:
  • Diabetes self-care declined during breast cancer treatment, with reduced adherence to diet, physical activity, glucose monitoring, and medication use, contributing to increased emotional distress.
  • Treatment-related symptoms disrupted established diabetes routines, complicating self-management.
  • 60% of patients reported uncontrolled glucose levels during treatment, with nearly half exceeding 200 mg/dL.
  • Cancer-related post-traumatic stress significantly impacted perceived diabetes control and emotional well-being.
  • Higher symptom burden correlated with poorer diabetes self-management and reduced physical function.
Interpretation:

The findings indicate that breast cancer treatment adversely affects diabetes management, leading to increased emotional distress and potential health complications, underscoring the need for integrated care.

Limitations:
  • Variation in study design, sample size, and outcome measures limited the evidence base, impacting generalizability.
  • Most studies were conducted in the US with small sample sizes.
  • The quasi-experimental study lacked a control group, and cross-sectional studies did not establish causal relationships.
Conclusion:

Diabetes self-care declines during breast cancer treatment, increasing the risk of poorer health outcomes and diabetes-related complications. A personalized diabetes care model showed promise in improving management and warrants further investigation.
