title: Sentinel lymph node biopsy in patients with breast ductal carcinomain situ: Chinese experiences.
abstract: The axillary treatment of patients with ductal carcinomain situ(DCIS) remains controversial. The aim of the present study was to evaluate the roles of sentinel lymph node biopsy (SLNB) in patients with breast DCIS. A database containing the data from 262 patients diagnosed with breast DCIS and 100 patients diagnosed with DCIS with microinvasion (DCISM) who received SLNB between January 2002 and July 2014 was retrospectively analyzed. Of the 262 patients with DCIS, 9 presented with SLN metastases (3 macrometastases and 6 micrometastases). Patients with large tumors diagnosed by ultrasound or with tumors of high histological grade had a higher positive rate of SLNs than those without (P=0.037 and P<0.0001, respectively). Of the 100 patients with DCISM, 11 presented with metastases. Younger patients had a higher positive rate of SLNs (P=0.028). According to the results of this study and the systematic review of recent studies, the indications of SLNB for patients with DCIS are as follows: SLNB should be performed in all DCISM patients and in those DCIS patients who received mastectomy, and could be avoided in those who received breast-conserving surgery. However, SLNB should be recommended to patients who have high risks of harboring invasive components. The risk factors include a large, palpable tumor, a mammographic mass or a high histological grade.
