Shared decision making in breast cancer: national practice patterns of surgeons.

BACKGROUND: The purpose of this study was to assess national practices of surgeons who treat breast cancer in order to identify opportunities to improve patient education. METHODS: In June 2012, the membership of the American Society of Breast Surgeons (ASBrS) (n = 2,818) was surveyed via email questionnaire to evaluate their current practice of shared decision making and informed consent for breast cancer patients. RESULTS: A total of 737 members (26 %) responded, including 384 breast surgeons and 306 general surgeons, 13 midlevel providers, and 25 other specialists. It was found that 90 % of surgeons spent more than 30 min meeting with a new cancer patient, and of these, 30 % spent more than an hour. Surgeons who spent more than 1 h face-to-face with a new cancer patient reported higher levels of overall patient knowledge compared with those who spent less (mean = 3.80 vs. 3.64 of 5; p = 0.001). Also, 89 % of respondents reported using educational tools, of whom more than 90 % used written tools. In addition, 65 % of members stated an interest in a free online educational tool if available and indicated a preference for a flexible tool that could be used by the patient alone or with a nurse. CONCLUSIONS: While practice patterns may vary, our results reveal that one-third of surgeons spend at least 1 h in consultation with a new breast cancer patient. More time spent translated to a higher perceived patient understanding of their disease and treatment options. Although the majority of surgeons currently use written materials, there was clear support for a free online educational tool.

Correlation of lymphoscintigraphy with the number of sentinel lymph nodes identified intraoperatively in patients with breast cancer.

BACKGROUND: Numerous studies have evaluated the benefit of performing lymphoscintigraphy for the sentinel lymph node procedure in breast cancer patients. The purpose of this study is to determine if lymphoscintigraphy accurately predicts the number of radioactive sentinel lymph nodes (SLNs) identified during surgery for breast cancer patients. METHODS: From October 2001 to June 2004, SLN biopsy was attempted in 112 patients with breast cancer using a combination of blue dye and radioisotope. Lymphoscintigraphy was performed in 98 of the patients. A lymph node was considered an SLN when it was stained with blue dye, had a blue lymphatic afferent, had increased radioactivity, or was abnormal by palpation. RESULTS: Lymphoscintigraphy accurately predicted the number of radioactive SLN identified intraoperatively in 47 patients. In 44 of the patients who did not have concordance, there were more SLN identified intraoperatively than were seen on lymphoscintigraphy. In the other 8 patients, there were fewer SLN identified intraoperatively than seen on lymphoscintigraphy. CONCLUSIONS: Lymphoscintigraphy accurately predicted the number of SLN identified intraoperatively in only 47% of the patients in this study. In a majority of the patients in whom the lymphoscintigraphy was not concordant, the number of SLN identified intraoperatively was underestimated. Thus, although lymphoscintigraphy is beneficial in showing that at least 1 radioactive SLN will be identified intraoperatively, it does not accurately predict the number.

Axillary lymph node metastases in patients with a final diagnosis of ductal carcinoma in situ.

BACKGROUND: Recent studies report the incidence of axillary metastases in patients with ductal carcinoma in-situ (DCIS) approaches 13%. The purpose of this study was to define the incidence of axillary micrometastases in patients with pure DCIS before and after the introduction of sentinel lymph node biopsy. METHODS: Patients with a final diagnosis of DCIS form the basis of this study. Data were entered prospectively into an Institutional Review Board approved Oracle database from January 1997 through July 2002. RESULTS: One hundred and thirty-four patients had lymph nodes evaluated. Ninety-eight percent of patients had no evidence of metastatic disease and 2% were found to have micrometastases. This was consistent in those who had level I or II lymph node sampling or both and those who had lymphatic mapping and a sentinel lymph node biopsy procedure. CONCLUSIONS: These data do not support axillary lymph node removal of any type in patients with pure DCIS.

Evaluation of intraoperative scrape cytology for sentinel lymph node biopsy in patients with breast cancer.

The techniques for intraoperative evaluation of sentinel lymph nodes (SLNs) vary. The most common methods include frozen section, imprint cytology/touch preparation cytology, and scrape cytology (SC). The purpose of this study was to evaluate whether there is concordance between the intraoperative SC and the final pathology of SLNs in patients with breast cancer. From October 2001 to June 2005, sentinel lymph node biopsies were attempted in 181 patients with breast cancer using a combination of blue dye and radioisotope. A lymph node was considered an SLN when it was stained with blue dye, had a blue lymphatic afferent, had increased radioactivity, or was abnormal by palpation. SLNs were successfully identified in 180 patients, for an identification rate of 99.4%. Forty-five patients had positive SLNs. In 16 (35%) of those patients, the SLNs were negative intraoperatively by SC. All of the false negatives occurred in SLNs with micrometastases. Thus, SC is an excellent method for identifying macrometastases intraoperatively, but less successful for micrometastases.
