The appropriateness of sentinel lymph node biopsy in the management of patients with biopsy diagnoses of ductal carcinoma in situ (DCIS) or DCIS with microinvasion (DCISM) has not been established. Three hundred forty-one patients presented with a biopsy diagnosis of DCIS or DCISM. Two hundred forty (70%) underwent sentinel node biopsy at their definitive(More)
OBJECTIVE The purpose of our study is to further clarify the incidence of ductal carcinoma in situ (DCIS) patients that are upstaged upon final pathology and/or have metastatic disease in the axilla. METHODS All patients were diagnosed with DCIS or DCIS with microinvasion (DCISm) on their diagnostic biopsy and received a sentinel lymph node (SLN) biopsy(More)
BACKGROUND Ipsilateral breast recurrence or second primary breast cancer can develop in patients who have undergone breast conservation and sentinel lymph node biopsy (SLNB). This brings into question the necessity of complete axillary lymph node dissection (CALND) versus a second SLNB (remapping). Our objective is to determine the feasibility of a(More)
BACKGROUND The significance of micrometastatic disease in the sentinel lymph nodes (SLN) of patients with invasive breast cancer has been questioned. The objective of our study was to review the impact of micrometastatic carcinoma detected by SLN biopsy. STUDY DESIGN Between January 1997 and May 2004, 2,408 patients with invasive breast cancer and an SLN(More)
The evaluation of sentinel lymph nodes (SLNs) for the presence of malignant epithelial cells is essential to the staging of breast cancer patients. Recently, increased attention has focused on the possibility that epithelial cells may reach SLNs by benign mechanical means, rather than by metastasis. The purpose of this study was to test the hypothesis that(More)
Age and body mass index (BMI) have been shown to correlate with an increased incidence of failure in identifying a sentinel lymph node (SLN). Mapping senior, overweight adults is common; therefore, the relationship of patient age and BMI on SLN biopsy success is essential. This study examines the mapping failures as they relate to age and BMI. From April(More)
The purpose of this study was to determine whether breast cancer patients who had prior breast augmentation presented at a more advanced stage than nonaugmented breast cancer patients, and to determine the mode of presentation and effectiveness of lymphatic mapping and sentinel lymph node biopsy in this same group of patients. A total of 4186 breast cancer(More)
As more women put off pregnancy until their 30s and beyond, the possibility of pregnancy-associated breast cancer (PABC) will rise. Treatment options for patients with PABC need to consider possible harm to the fetus. The goal of this study is to review our institution's experience with sentinel lymph node (SLN) biopsies in patients with PABC. A(More)
BACKGROUND Frozen section and intraoperative imprint cytology (IIC(N)) are 2 methods used for intraoperative pathologic assessment of sentinel lymph nodes (SLNs). The SLN evaluation of patients with invasive lobular carcinoma (ILC) results in a relatively high number of false-negative results using either of these methods. The purpose of this study was to(More)
BACKGROUND The surgical management of breast cancer has changed markedly with the development of lymphatic mapping and sentinel lymph node (SLN) biopsy. Lymphatic mapping technique varies with respect to injection method, mapping agent, and surgical technique. The decision to pursue the internal mammary nodes (IMN) is another source of controversy.
