One hundred three patients with invasive breast cancer exhibiting negative frozen section evaluation of their sentinel node, but later found to have isolated tumor cells (n = 46), micrometastasis (n = 46), or metastases (n = 11) in their sentinel node by permanent sections or immunohistochemistry, were enrolled in this prospective cohort study and underwent completion axillary dissection.
There is much yet to be learned, and it is likely that axillary dissection in every case with micrometastases will constitute overtreatment for some patients.
However, axillary dissection was subsequently performed in the last group if involvement of axillary nodes was detected during follow-up.
For patients who have access to an experienced team and have node-negative axilla, the recommendation is for sentinel node mapping; only if the sentinel node is positive or could not be identified would the woman then go on to formal axillary dissection, he said.
If they are found to contain tumour, an axillary dissection is performed.
She must then undergo additional surgery and anesthesia in order to have an axillary dissection, which can be financially costly, as well as psychologically burdensome for the patient.
Few long-term follow-up studies prove sentinel lymph node biopsy (SLNB) effectively stages breast cancer without the further evaluation of a completion axillary dissection.
Older women who had breast-conserving surgery without axillary dissection were almost twice as likely to die from their breast cancer within 7 years as women who received either axillary dissection, radiotherapy, or both in a large retrospective cohort study
They were asked whether they were performing SLNB as part of an organized protocol and whether an axillary dissection followed SLNB.
The RIGS technology study will involve women who have biopsy-proven breast cancer and who will undergo a partial or total mastectomy and an axillary dissection.
