OBJECTIVE: This study aimed to evaluate the association of different patterns of breast edema and clinical-pathological features and axillary lymph node (ALN) status in early invasive ductal carcinoma (IDC) for simple and readily available assessment and to guide surgeons to perform sentinel lymph node biopsy for selected patients.
MATERIALS AND METHODS: This retrospective analysis involved 207 individuals with clinical T1-T2 stage IDC. The clinical-pathological features of the patients were compared with different breast edema and ALN statuses. Independent risk factors for ALN metastasis were verified using multivariate logistic regression analysis.
RESULTS: ALN metastasis was confirmed in 100 of 207 patients (48.3%) with early-stage IDC. Significant differences were found between different ALN states for tumour size, clinical T stage, and breast edema (P <0.05). The clinical T2 stage (odds ratio-1.882, p=0.043) and moderate to severe edema (odds ratio-10.869, p=0.004) were independent risk factors for ALN metastasis. Moreover, better prognostic factors, including smaller tumour size, lower Ki-67 index and histologic grade, luminal A subtype, and lower incidence of lymph node metastasis, were more frequently found in patients with no breast edema (p<0.05).
CONCLUSION: Breast edema can be considered a promising feature to improve the predictive performance of pathological ALN status in patients with early-stage breast cancer and thus may contribute to preoperative treatment planning.
