title: How many cases are enough for accreditation in sentinel lymph node biopsy in breast cancer?
abstract: BACKGROUND
  There is considerable argument concerning the number of sentinel node biopsy cases with axillary dissection that surgeons should perform before they are eligible on abandoning axillary dissection in negative sentinel node patients.
  
  
  METHODS
  Papers that (1) address directly or indirectly the subject of credentialing or of learning curve, (2) report on a surgeon's performance, (3) are reported as feasibility or learning curve studies, or both, (4) discuss the learning curve issue, and (5) express an expert's opinion on the learning curve.
  
  
  CONCLUSIONS
  The number of procedures of the learning curve can not be fixed for all surgeons. Only surgeons in specialized breast cancer centers can succeed in meeting current recommendations with 20 to 30 cases. Surgeons from affiliated community hospitals will need more than 30 cases, whereas broad-based surgeons might need as many as 60 cases with their current caseload. Not all surgeons will be able to offer the procedure to their patients by the current recommendations.
