Clinical Report: Evaluating the Prognostic Value of Nutrition-Based Indices in Breast Cancer

Overview

This systematic review and meta-analysis evaluated the prognostic value of the Prognostic Nutritional Index (PNI) and Controlling Nutritional Status (CONUT) score in breast cancer. Higher PNI was associated with improved overall survival (OS) and disease-free survival (DFS), while higher CONUT correlated with poorer OS and DFS.

Background

Breast cancer remains the leading malignancy among women, with significant mortality rates. Prognostic stratification is crucial for treatment planning, yet existing methods can be costly and complex. Nutrition and inflammation markers like PNI and CONUT may offer accessible prognostic insights, potentially guiding clinical decisions.

Data Highlights

IndexOutcomeHR/OR95% CIP-value
PNIOverall Survival0.490.39-0.61<0.00001
PNIDisease-Free Survival0.690.58-0.81<0.00001
CONUTOverall Survival1.771.29-2.440.0005
CONUTDisease-Free Survival2.081.75-2.47<0.00001

Key Findings

  • Higher PNI is linked to improved overall survival (OS) and disease-free survival (DFS).
  • Higher CONUT scores correspond to poorer OS and DFS outcomes.
  • PNI and CONUT may serve as candidate prognostic indicators in breast cancer.
  • Substantial between-study variability was noted in the prediction intervals for both indices.
  • The evidence for PNI's association with pathological complete response (pCR) was inconclusive.

Clinical Implications

Clinicians may consider incorporating PNI and CONUT scores into their prognostic assessments for breast cancer patients. These indices could aid in identifying patients at higher risk for poor outcomes, potentially guiding more personalized treatment strategies.

Conclusion

The findings suggest that PNI and CONUT are valuable prognostic tools in breast cancer, with implications for patient management and treatment planning. Further research is warranted to clarify their roles in clinical practice.
