Stability and variability of molecular subtypes: comparative analysis of primary and metastatic triple-negative breast cancer

Cancer Biology & Medicine 2024年第9期21卷 784-798页

作者： Xiuzhi Zhu Xiaohan Ying Yin Liu Yunyi Wang Li Chen Zhiming Shao Xi Jin Yizhou Jiang Zhonghua Wang Key Laboratory of Breast Cancer in Shanghai Shanghai Institute of Infectious Disease and Biosecurity Department of Oncology Shanghai Medical College Fudan University department of Breast Surgery Fudan University Shanghai Cancer Center

Objective: Triple-negative breast cancer(TNBC) is a heterogeneous and aggressive cancer. Although our previous study classified primary TNBC into four subtypes, comprehensive longitudinal investigations are ***: We assembled a large-scale, real-world cohort comprised of 880 TNBC patients [465 early-stage TNBC(e TNBC) and 415 metastatic TNBC(m TNBC) patients] who were treated at Fudan University Shanghai Cancer Center. The longitudinal dynamics of TNBC subtypes during disease progression were elucidated in this patient cohort. Comprehensive analysis was performed to compare primary and metastatic lesions within specific TNBC ***: The recurrence and metastasis rates within 3 years after initial diagnosis in the e TNBC cohort were 10.1%(47/465). The median overall survival(OS) in the m TNBC cohort was 27.2 months [95% confidence interval(CI), 24.4±30.2 months], which indicated a poor prognosis. The prognostic significance of the original molecular subtypes in both e TNBC and m TNBC patients was confirmed. Consistent molecular subtypes were maintained in 77.5% of the patients throughout disease progression with the mesenchymal-like(MES) subtype demonstrating a tendency for subtype transition and brain metastasis. Additionally, a precision treatment strategy based on the metastatic MES subtype of target lesions resulted in improved progression-free survival in the FUTURE ***: Our longitudinal study comprehensively revealed the clinical characteristics and survival of patients with the original TNBC subtypes and validated the consistency of most molecular subtypes throughout disease progression. However, we emphasize the major importance of repeat pathologic confirmation of the MES subtype.
