Abstract
Background
This study aimed to collect the factors underlying the metastasis of breast cancer and sentinel lymph node, and to screen and analyze the risk factors of sentinel lymph node metastasis, so as to provide reference and basis for clinical work.
Methods
A total of 100 patients with breast cancer were enrolled in the study. These patients received treatment in our hospital from May 2017 to May 2020. The general information, the characteristics of the color Doppler echocardiography, molybdenum, conventional pathology and molecular pathology of the patients were collected. The influencing factors of sentinel lymph node metastasis in breast cancer patients were retrospectively analyzed.
Results
In this study, age, tumor diameter and BI-RADS category, pathology type, expression profiles of CK5/6, EGFR, and CK19, and TP53 and BRAC1/2 mutations were independent risk factors for sentinel lymph node metastasis in breast cancer (P<0.05). The number and locations of tumors, the quadrant of tumors, the regularity of tumor margins, the presence of blood flow signals, the presence of posterior echo attenuation, the presence of calcification, histological grade, molecular typing, and mutations of BRAF, ATM and PALB2 were irrelevant factors (P>0.05).
Conclusions
In conclusion, age, tumor diameter, Bi-rads category, invasive type, expression of CK5/6, EGFR and CK19, and mutations of TP53 and BRAC1/2 were positively correlated with sentinel lymph node metastasis. They are independent risk factors that should be paid more attention in clinical studies, to strengthen the management and control of sentinel lymph node metastasis of high-risk breast cancer, and support early chemotherapy or targeted therapy.
