AIMS: The American Joint Committee on Cancer staging system for breast carcinomas has been revised. According to this revised staging system, metastasis to infraclavicular lymph nodes and number of positive axillary nodes have prognostic significance and a new stage, stage IIIC, has been introduced. The aim of this study is to investigate the association of positive axillary nodes by level and number with survival and stage migration between the old and the new stages in a large series of mastectomy patients.
METHODS: Data from 1277 consecutive breast cancer patients treated by mastectomy were studied, retrospectively. Prognostic value of number of positive axillary nodes and entirely invasion of apex axillary nodes were analysed. Survival curves were generated by Kaplan-Meier method, and multivariate analysis was performed by Cox proportional hazard model.
RESULTS: Five-year survival rates for metastasis to axillary level III and for stage IIIC breast cancer were 35.4 and 38.2%, respectively. Metastases to apex axillary nodes, 4-9 and 10 or more positive lymph nodes were found to be adverse and independent prognostic factors for survival in lymph node positive patients.
CONCLUSION: Invasion of infraclavicular nodes and 4-9 and > or =10 positive axillary lymph nodes were independent predictors for survival in node positive breast carcinomas in this series. Patients with the new stage IIIC had the worst survival among breast cancer patients.
