Incidence of and risk factors for sentinel lymph node metastasis in patients with a postoperative diagnosis of ductal carcinoma in situ.

摘要

SLN positivity is rare in women with a histopathological diagnosis of pure DCIS. Additional primary tumour assessment may reveal occult invasion in both SLN metastasis-positive and -negative patients. The value of performing SLN biopsy in the setting of a preoperative diagnosis of DCIS was limited, and current Swedish practice should therefore be questioned.
