Clinical Scorecard: Creation and assessment of a nomogram for forecasting lymph node metastasis in breast cancer patients undergoing axillary reverse mapping

At a Glance

Key Highlights

• ARM lymph nodes identified in 92.81% of patients with 23.24% showing metastasis.
• Independent predictors of metastasis include menarche age ≤ 12 years and elevated fibrinogen.
• Nomogram demonstrated excellent discrimination (AUC = 0.934) in development cohort.
• Validation cohort showed acceptable discrimination (AUC = 0.826).
• Study supports selective ARM node preservation to reduce lymphedema risk.

Guideline-Based Recommendations

Diagnosis

• Use of a preoperative nomogram to predict ARM lymph node metastasis.

Management

• Consideration of independent predictors in surgical planning.

Monitoring & Follow-up

• Pathological examination of identified ARM lymph nodes.

Risks

• Potential for ARM lymph nodes to harbor metastases.

Patient & Prescribing Data

Patients with stage I-III breast cancer undergoing axillary surgery.

Incorporation of inflammatory and tumor markers, imaging, and ARM anatomy in preoperative assessment.

Clinical Best Practices

• Utilize ARM to protect upper limb lymphatic drainage during surgery.
• Assess risk factors for lymph node metastasis preoperatively.
