Subareolar and periareolar radioactive colloid injection techniques were associated with SLN identification rates of 99.3% and 95.6%, respectively, with false-negative rates of 8.3% and 8.9%, respectively. Results An SLN biopsy was performed in 3961 patients using blue dye alone or radioactive colloid plus blue dye. Main Outcome Measures The SLN identification and false-negative rates. Most surgeons had little or no experience with SLN biopsy before participation in this study. Injection technique was determined by the preference of each participating surgeon. Interventions All patients underwent attempted SLN biopsy followed by completion axillary dissection. Patients A total of 3961 individuals with clinical stage I and II breast cancer. ![]() Hypothesis Subareolar or periareolar injection of radioactive technetium sulfur colloid is equivalent to other injection techniques for breast cancer sentinel lymph node (SLN) biopsy.ĭesign and Setting Prospective, multicenter clinical trial.
