[Early Recurrence of Breast Cancer after the Primary Treatment: Analysis of Clinicopathological and Radiological Predictive Factors].

PURPOSE

To evaluate the value of clinicopathologic factors and imaging features of primary breast cancer in predicting early recurrence after the primary treatment.

MATERIALS AND METHODS

We enrolled 480 patients who had been followed-up after breast-conserving surgery and adjuvant therapy from January 2010 to December 2014 at our hospital. Early recurrence was defined as recurrence within 3 years after completion of primary treatment, and univariate and multivariate logistic regression analyses were performed to determine the clinicopathologic and imaging predictive factors of early recurrence.

RESULTS

In the univariate analysis, among the clinicopathologic factors, advanced stage ( = 0.021), high histologic grade ( < 0.001), estrogen receptor negative ( = 0.002), high Ki-67 proliferation index ( = 0.017), and triple-negative breast cancer ( = 0.019), and among the imaging features, multifocality ( < 0.001), vessels in the rim on Doppler ultrasonography (US) ( = 0.012), and rim enhancement ( < 0.001) on magnetic resonance imaging of the breast were significantly associated with early recurrence. In the multivariate analysis, advanced stage [odds ratio (OR) = 3.47; 95% confidence interval (CI) 1.12-10.73; = 0.031] and vessels in the rim on Doppler US (OR = 3.32; 95% CI 1.38-8.02; = 0.008) were the independent predictive factors of early recurrence.

CONCLUSION

Vascular findings in the rim of the primary breast cancer on Doppler US before treatment is a radiologic independent predictive factor of early recurrence after the primary treatment.
