Computed Tomography (CT) Reconstruction for Axillary Lymph Node Structure

Computed Tomography (CT) Reconstruction for Axillary Lymph Node Structure: a Prospective Observational Study Evaluating Response in Axillary Lymph Nodes of Breast Cancer After Neoadjuvant Chemotherapy

This is a prospective, single-center, non-randomized, non-controlled observational study.

The negative predictive value of ultrasound for lymph node with neoadjuvant chemotherapy is low, magnetic resonance imaging (MRI) or PET/CT did not significantly improve specificity to axillary lymph node. The aim of this study is to determine performance of computed tomography (CT) reconstruction on evaluation of lymph node status after neoadjuvant chemotherapy in breast cancer patients.

Inclusion Criteria:

• Invasive breast cancer with axillary lymph node metastasis by confirmed by fine needle aspiration (FNA) or core needle biopsy (CNB).
• Underwent computed tomography (CT) reconstruction for assessment of axillary lymph node status before and after neoadjuvant chemotherapy (NAC).
• Attend the study voluntarily, sign the informed consent.

Exclusion Criteria:

• Contradiction for adjuvant chemotherapy.
• Contradiction for proceeding surgery.
