Summary
Dissecting axillary lymph nodes (LNs) levels I and II offers sufficient prognostic data. However, including level III LNs is crucial for preventing recurrence, especially when metastases are present in lower levels.
Area of Science:
- Oncology
- Surgical Pathology
Context:
- Axillary lymph node dissection (ALND) is a standard procedure for breast cancer staging.
- Histological assessment of lymph nodes (LNs) is critical for determining prognosis and guiding treatment.
Purpose:
- To evaluate the prognostic sufficiency and recurrence prevention efficacy of dissecting different levels of axillary lymph nodes (LNs).
Summary:
- A retrospective analysis of 1047 patients undergoing total ALND (levels I-III) found that dissecting only levels I and II missed minimal false negatives (0.2%) and misclassified prognosis in 5% of cases.
- However, metastases in level III were found in 29.5% of node-positive patients, necessitating its inclusion for recurrence prevention.
- Dissection of levels I and II alone provides adequate prognostic information, but level III dissection is recommended unless metastases in levels I and II are definitively excluded intraoperatively.
Impact:
- Dissection of axillary lymph nodes levels I and II provides sufficient prognostic information.
- Inclusion of level III lymph nodes in dissection is essential for preventing axillary recurrences.
- Intraoperative assessment of lymph node metastases in levels I and II could potentially allow for omission of level III dissection.
