Prognostic predictive value of Ki-67 in stage I-II triple-negative breast cancer.

Our research aimed to determine an optimal cutoff value and investigate the prognostic predictive function of Ki-67. We retrospectively enrolled 1146 patients diagnosed with stage I-II triple-negative breast cancer. Disease-free and overall survival were analyzed using the Kaplan-Meier method and the Cox regression model.

Treatments and Prognosis of the Breast Ductal Carcinoma In Situ.

Introduction: With progress in treatments, breast ductal carcinoma in situ (DCIS) outcomes have substantially improved. However, as various treatment methods are used in different countries and institutions, consensus on the optimal treatment method is lacking. This study aimed to analyze the prognostic factors and provide a reference for optimizing the clinical treatment of DCIS.
