How many ELNs are optimal for breast cancer patients with more than three PLNs who underwent MRM? A large population-based study

BACKGROUND: Few studies have focused on the optimal threshold of examed lymph nodes (ELNs) for breast cancer patients with more than three positive lymph nodes after modified radical mastectomy. MATERIALS AND METHODS: The X-tile and the minimum P-value models were applied to determine the optimal th...

Sumario:BACKGROUND: Few studies have focused on the optimal threshold of examed lymph nodes (ELNs) for breast cancer patients with more than three positive lymph nodes after modified radical mastectomy. MATERIALS AND METHODS: The X-tile and the minimum P-value models were applied to determine the optimal threshold. Cox proportional hazard analysis was used to analyze the cancer-specific survival and perform subgroup analysis. RESULTS: The results showed that 12 ELNs was the optimal threshold for these patients, and the patients with >12 ELNs had a better cancer-specific survival benefit compared with the patients with <12 ELNs (P<0.001). CONCLUSION: The number 12 can be selected as the optimal threshold of ELNs for breast cancer patients with >3 positive lymph nodes after modified radical mastectomy.
