ObjectiveTo sort out the key evidence-based data and recent advances in the systemic treatment of advanced triple-negative breast carcinoma (TNBC), to summarize the therapeutic strategies so as to provide guidance for clinical practice. MethodsThe key evidence and research progress on immune checkpoint inhibitors, antibody–drug conjugates (ADCs), poly ADP-ribose polymerase (PARP) inhibitors, anti-angiogenic agents, and novel microtubule inhibitors were summarized. ResultsThe treatment landscape for advanced TNBC has shifted from chemotherapy-centric approaches to biomarker-driven, stratified precision therapy. Based on programmed cell death ligand 1 (PD-L1) expression levels, immune therapy combined with chemotherapy is prioritized. For cases with germline breast cancer gene 1/2 (gBRCA1/2) mutations, PARP inhibitors are recommended. ADCs are suggested for second-line treatment, while novel microtubule inhibitors, either alone or in combination with anti-angiogenic agents, are preferred for later-line therapy to extend patient survival. ConclusionDynamic monitoring of molecular biomarkers such as PD-L1 and gBRCA, combined with sequential or combined "targeted–immunotherapy–ADC" regimens in a "chemotherapy-free" approach, has shown promise in improving overall survival in advanced TNBC.
ObjectiveTo explore the clinical application of oncoplastic surgery in breast-conserving surgery after neoadjuvant chemotherapy.MethodsFrom May 2016 to May 2018, 32 breast cancer patients (cT2–3N0–3M0) who were scheduled for neoadjuvant chemotherapy (NAC) and agreed to accept breast-conserving surgery after NAC in the Henan Tumor Hospital were enrolled into the retrospective study. These patients were originally unable to perform traditional breast conserving surgery because of the size or location of the tumor. We observed the success rate, safety and cosmetic effects of breast-conserving therapy, which were applicated of tumor down-staging after neoadjuvant chemotherapy combined with oncoplastic surgery.ResultsIn this study, after neoadjuvant chemotherapy, 31 patients achieved CR or PR, and 1 patient had SD. All 32 patients underwent breast-conserving surgery successfully, 3 patients underwent breast-conserving combined with volume replacement, and 29 patients underwent breast-conserving combined with volume displacement. One patient was not satisfied with the cosmetic effects, the other patients were satisfied or basically satisfied with the cosmetic effects. The median follow-up was 18 months (5–24 months), and no local recurrence or distant metastasis was found in 32 patients.ConclusionsBy tumor down-staging after neoadjuvant chemotherapy combined with oncoplastic surgery, we can make some patients who are originally not suitable for breast conserving due to tumor size and tumor location succeed in breast-conserving therapy, and the safety and cosmetic effect are basically satisfied.
