The Accuracy of Sentinel Node Biopsy of Breast Cancer With Sonographic Abnormal Axillary Lymph Nodes
Breast Cancer
About this trial
This is an interventional diagnostic trial for Breast Cancer focused on measuring Breast cancer, Sentinel lymph node biopsy, Ultrasonography, Fine needle aspiration
Eligibility Criteria
Inclusion Criteria:
- histologically confirmsed primary breast cancer by core neelde biopsy or excisional biospy
- abnormal axillary lymph node was found by ultrasound examination before SLNB (abnormal nodes were defined as completely hypoechoic node, asymmetric focal hypoechoic node, cortical lobulation and cortical thickness >3mm)
- ultrasound-guided FNA cytology of these nodes were performed
- the result of FNA cytology was negative (no tumour cell was found)
- patient planed to perform SLNB
Exclusion Criteria:
- pathological diagnosed ductal carcinoma in situ by excisional biospy
- abnormal axillary lymph node was found by ultrasound examination but FNA cytology of these nodes were not performed
- the result of FNA cytology was positive (tumour cell was found)
- T4d tumour
- patient has recieved neo-adjuvant system therapy
Sites / Locations
- Breast cancer, Peking University Cancer Hospital & Institute
Arms of the Study
Arm 1
Experimental
negative FNA result of abnormal node
Axillary ultrasound examination was undergone for all breast cancer patients before sentinel lymph node biopsy (SLNB). If abnormal axillary lymph node was found, ultrasound-guided FNA cytology of these nodes were performed. The abnormal nodes were defined as completely hypoechoic node, asymmetric focal hypoechoic node, cortical lobulation and cortical thickness >3mm. Patients with negative results of FNA would undergo SLNB. Technetium-99m-labeled Rituximab was used for lymphatic mapping. Before the SLNB operation, a hookwire was placed at the suspicious axillary lymph node by ultrasound guidance. In the SLNB operation, radioactive nodes and wire-localized nodes were removed and labeled separately for pathological examination.
