Sentinel lymph node biopsy in breast cancer.
1Department of Surgery, St Vincents University Hospital, Dublin 4, Ireland.
Summary
Sentinel lymph node (SLN) biopsy accurately stages breast cancer patients with minimal invasiveness. This technique offers lower morbidity compared to traditional lymph node dissection for screen-detected cancers.
Area of Science:
- Oncology
- Surgical Pathology
- Breast Cancer Research
Background:
- The sentinel lymph node (SLN) is the primary site for lymphatic drainage from a tumor.
- Traditional axillary lymph node dissection carries significant morbidity.
- Approximately 20% of screen-detected breast cancers involve axillary lymph nodes.
Purpose of the Study:
- To evaluate the utility of sentinel node biopsy in staging breast cancer.
- To assess the minimally invasive nature of SLN biopsy compared to axillary dissection.
Main Methods:
- Identification of the sentinel lymph node, the first node receiving lymphatic drainage from the tumor.
- Biopsy of the identified sentinel node for staging purposes.
Main Results:
- Sentinel node biopsy is a minimally invasive procedure.
- This technique results in lower patient morbidity than traditional axillary lymph node dissection.
Conclusions:
- Sentinel node biopsy provides accurate staging for breast cancer patients.
- It is a preferred minimally invasive alternative to axillary lymph node dissection for screen-detected cancers.
