Précis: Total number of lymph nodes predicts outcome of node-negative breast cancer
IntroductionThe histologic status of axillary lymph nodes is one of the most important prognostic indicators in patients with breast cancer. However, for patients with negative axillary lymph nodes, the relationship between the total number of lymph nodes removed at the time of surgery and clinical outcome remains unknown. In this study, the researchers investigated this specific issue.
MethodThe number of lymph nodes in 290 patients with node-negative breast carcinoma who underwent axillary dissection was assessed. The patients were followed for a median period of 103 months.
- Patients with 20 lymph nodes or more were 4.33 times more likely than those with fewer lymph nodes to die of metastatic breast carcinoma within 5 years.
- The 5-year survival rate was 84.7% for patients with 20 or more lymph nodes and 95.3% for those with fewer.
