Task: Answer Verification
Input (English): Question: Is sentinel lymph node biopsy necessary in patients diagnosed with ductal carcinoma in situ of the breast by stereotactic vacuum-assisted biopsy?
Answer: The rate of lymph node metastasis was extremely low (0.62 %), even when invasive carcinoma was identified on excision in patients initially diagnosed with DCIS by stereotactic VAB. Because of the low prevalence of metastatic involvement, the cessation of SLNB is a reasonable consideration in patients initially diagnosed with DCIS by stereotactic VAB.
Output (English): no
