Inetetamab Combined With Paclitaxel With/Without Pertuzumab for Previously Treated HER2-positive Advanced Breast Cancer

Официальное название

The Real World Study of First Line Treatment of HER2 Positive Recurrent/Metastatic Breast Cancer With Inetetamab Combined With Paclitaxel With/Without Pertuzumab（INTPOWER）

Обзор

This study is designed to comprehensively evaluate the HER2 positive recurrent/metastatic breast cancer patients in the real world who receive the combination of Inetetamab and Paclitaxel ± Pertuzumab, including basic characteristics, efficacy and safety. The results of this study are helpful to further understand the efficacy and safety of HER2 positive patients with recurrent/metastatic breast cancer who receive the combination of Inetetamab and Paclitaxel ± Pertuzumab in the first line, and help clinical decision-making.
