简要总结
This study aimed to assess the prevalence of upgrade to invasive breast cancer and axillary lymph node metastasis in patients who were diagnosed with DCIS on biopsy and subsequently underwent mastectomy with axillary surgery to establish the need for SLNB. Furthermore, we explored the clinicopathologic features related to the upgrade to invasive breast cancer and axillary lymph node metastasis.
