Özet

Aim: In this study we evaluated the prognostic value of the lymph node ratio. (LNR: defined as the number of involved nodes divided by the number of the nodes examined). Patients and Methods: In this retrospective study, patients underwent axillary dissection due to breast cancer were examined. We evaluated 348 women underwent axillary dissection for nonmetastatic breast cancer in 9 Eylül University Hospital between 2006 and 2016. LNR were divided into three groups as low, intermediate and high risk (low, ≤0.20; intermediate, 0.21-0.65; high, > 0.65). Overall survival of the patients was estimated by the Kaplan Meier method for LNR. Overall relative mortality risks associated with LNR and pN were calculated by Cox regression. Results: The mean survival was 95.1 months LNR high-risk group, while it was 100 months in N3 group. Even though it was not statistically significant, a lower survival rate of less than 5 months was observed in the LNR high group (P 0.65 HR 3.08; p=0.002). Conclusion: LNR is highly significant in breast cancer and it provides more valuable information rather than TNM in terms of prognosis. Therefore, we think that, LNR can be used as a beneficial tool in breast cancer staging.
