Suggested issues for improvement in sentinel lymph node biopsy quality indicators

Quality indicatorComments/suggestions
Pathologic evaluation protocolPrerequisite, but does not speak of the surgeon’s skill.
Pathologic reporting by AJCC guidelinesPrerequisite, but does not speak of the surgeon’s skill.
Protocol for injection of radiocolloidPrerequisite, but does not speak of the surgeon’s skill.
Proper identification of SLNNo changes necessary.
SLNB performance in eligible patientsTarget rates should be redefined. Preoperative assessment of axilla by MRI and ultrasound can decrease the number of eligible patients. Patients other than those with T1 tumours should be included (e.g., T2, T3).
SLNB concurrent with lumpectomy/mastectomyLack of strong evidence against nonconcurrent breast primary surgery and axillary staging procedure.
Completion ALND for positive SLNBRequires redefinition given the fact there is evidence that ALND can be avoided patients with micrometastasis and isolated tumour cells.
SLNB performance in ineligible patientsBetter definition of ineligible patients is necessary.
Axillary node positivity rateNo changes necessary.
Number of nodes removedRequires an upper limit to the target rate.
Axillary recurrence rate at 5 yearsNo changes necessary.
  • AJCC = American Joint Committee on Cancer; ALND = axillary lymph node dissection; MRI = magnetic resonance imaging; SLN = sentinel lymph node; SLNB = sentinel lymph node biopsy.
