Background: This study was performed to determine if surgeons' performance of sentinel lymph node biopsy (SLNB) for breast cancer varied with time and to devise a method to continuously evaluate that performance.

Methods: We retrospectively examined the SLNB experience of 13 community surgeons performing 765 SLNBs and 579 concomitant axillary dissections. False-negative rates (FNRs) were assessed for individuals and cohorts defined by caseload.

Article Synopsis
  • The study evaluates the practice patterns of sentinel-node biopsy (SNB) for breast cancer in British Columbia, five years after its introduction, focusing on surgeons, pathologists, and nuclear medicine physicians.
  • Surveys revealed that by 2001, only 19% of breast cancer surgeons in the region were performing SNB, with about half of them involved in validation studies and many lacking data management support.
  • Significant inconsistencies were found regarding the definitions, indications, and techniques used for SNB among practitioners, alongside variations in lymphatic mapping protocols across nuclear medicine departments.

Background: Radiofrequency ablation (RFA) is a minimally invasive thermal ablation technique. This study reports the safety and efficacy of RFA as a minimally invasive strategy for breast cancers <3 cm diameter in postmenopausal women.

Methods: Twenty-two postmenopausal women (aged 60 years or older) with clinical T-1N0 core biopsy proven breast cancers were studied.

Background: This study evaluated the outcomes of the first 5 years of sentinel node biopsy (SNB) in British Columbia (BC), Canada, 1996 to 2001.

Methods: There were 547 SNB procedures for breast cancer performed by 29 surgeons at 12 hospitals in BC between October 1996 and July 2001. Identification, accuracy, and false-negative rates were determined and correlated to patient, tumor, and surgical factors with the chi-square test.
