Abstract

The present study was designed to establish a model for the early identification of sentinel lymph node (SLN) metastasis in patients with breast cancer (BC). The SLN metastasis predictive model was established with a retrospective training set of 365 patients with BC and was re‑evaluated using a prospective validation set of 402 patients with BC. The multivariable analysis indicated that the tumor diameter [odds ratio (OR), 1.189; 95% confidence interval (CI), 1.124‑1.257; P<0.001], menopause (OR, 1.011; 95% CI, 0.603‑1.436; P<0.001), estrogen receptor (ER) expression (OR, 3.199; 95% CI, 1.077‑6.567; P=0.043) and contrast‑enhanced ultrasonography (CEUS) type (OR, 10.563; 95% CI, 6.890‑28.372; P<0.001) were independent predictors of SLN status in patients with BC. The SLN metastasis predictive model was as follows: (0.173 x tumor diameter)‑(4.490 x menopause) + (2.322 x ER) + (5.445 x CEUS type)‑1.9521. In the training set, the model was highly sensitive (83.6%) and specific (94.3%) for the early identification of SLN metastasis. Similarly, in the validation set, the model was highly sensitive (70.4%) and specific (89.5%) for the early identification of SLN metastasis in patients with BC. Overall, in the present study, a model was successfully established to predict SLN metastasis in patients with BC that includes tumor diameter, menopausal status, ER expression and CEUS detection.
