ReviewClinical applications of sentinel lymph node biopsy in ductal carcinoma in situ of the breast: a dilemma.
Breast cancer is the fifth most common cause of cancer deaths in the world, which often spreads first to the axillary lymph nodes (ALN) from the primary tumor. ALN helps clinician stage breast cancer. In addition, it is one of the key prognostic factors for patients with invasive breast cancer. ⋯ The potential benefit of accurately upstaging patients with DCIS and the minimal invasiveness of SLNB justify use of SLNB in selected high-risk DCIS patients. At least DSIS with microinvasion, have DCIS of sufficient extent on mammography or MRI, or indicated invasive or microinvasive focus by final histological examination, are recommended for SLNB. Moreover, large randomized trials to evaluate the usefulness of SLNB in DCIS patients after long-term follow-up on local control and survival are required for further evaluation.
