[Expert consensus on clinical application of next-generation sequencing in advanced breast cancer (2024 edition)].

Breast cancer is the most common malignant tumor among women in the world. According to data from the World Health Organization, in 2020, there were approximately 2.26 million new breast cancer cases worldwide, accounting for 11.7% of all new cancer cases. In recent years, with the rapid development of molecular biology and gene detection technology, the research on advanced breast cancer continues to deepen, and the treatment methods are constantly enriched. Gene targeted therapy significantly prolongs the survival period of patients with advanced breast cancer, which is of great significance for molecular pathological diagnosis, targeted drug selection and treatment mode optimization of patients with advanced breast cancer. Based on the development of literature and clinical research, the consensus expert committee formulated the "Expert consensus on clinical application of next-generation sequencing in advanced breast cancer (2024 edition)". Compared with the "Chinese Expert Consensus on Hot Issues of Gene Testing for Advanced breast cancer (2021)", the 2024 consensus adopts new evidence-based medical evidence, aiming to provide more comprehensive gene testing information for patients with advanced breast cancer, so as to develop more accurate treatment strategies.
