From: Prognostic value of tumor necrosis based on the evaluation of frequency in invasive breast cancer
A 5-year DFS of patients with IBC stratified by risk of TN in the training set showed that the patients with high-risk TN had worse 5-year DFS than patients with no necrosis, while the patients with low-risk TN had a 5-year DFS comparable to patients with no necrosis. B 5-year DFS of patients with IBC stratified by risk of TN in the validation set also showed the same results as in the training set
