Analysis Of The Value Of Ultrasound Combined With Molybdenum Target To Avoid Sentinel Lymph Node Biopsy For Early Invasive Breast Cancer

Objective:To analyze the value of ultrasound combined with molybdenum target in early invasive breast cancer patients with tumor diameter T ≤ 2cm to avoid sentinel lymph node biopsy(SLNB).Methods:A retrospective study was conducted on 122 early invasive breast cancer patients with tumor diameter T ≤ 2 cm and SLNB was performed on them during the operation in the First Affiliated Hospital of Chongqing Medical University from January 2018 to June 2019.The results of ultrasound,molybdenum target,magnetic resonance imaging(MRI)and SLNB were collected and compared with the results of postoperative axillary lymph node biopsy.Results:Of the early invasive breast cancer patients with tumor diameter T ≤2cm,29 patients showed positive results of postoperative axillary lymph node biopsy.In the Kappa consistency test of SLNB,ultrasound,MRI and molybdenum target with gold standard,the Kappa value was 0.721,0.668,0.620,0.422,respectively,and the difference was statistically significant(p< 0.05).In the kappa test of ultrasound,molybdenum target and MRI in parallel or in parallel with gold standard,the Kappa value of ultrasonic parallel molybdenum target was the highest(Kappa=0.702,p < 0.05).ConclusionThe result of ultrasonic parallel mammography in the diagnosis of axillary lymph node metastasis is highly consistent with the gold standard,which provides strong evidence support for the early invasive breast cancer patients with tumor diameter T ≤ 2cm to avoid SLNB.
