Abstract

Neoadjuvant chemotherapy (NAC) is the standard of care for locally advanced breast cancer, but the response to chemotherapy is unpredictable due to unknown information on the tumor drug sensitivity. Patient-derived organoids (PDOs) have recently been revealed to be a promising platform for assessing drug sensitivity in many cancers. A 46-year-old woman presented to the hospital due to an accidentally discovered mass in the left breast. Based on core-needle biopsies, pathologic examination showed invasive breast cancer in both breasts. In combination with immunohistochemistry, the patient was diagnosed with left breast cancer IIB with axillary lymphatic metastasis and right breast cancer IIA. The NAC with albumin-bound paclitaxel, epirubicin and cyclophosphamide was used. Although partial response was assessed overall, the left tumor did not lessen significantly; thus, organoids from bilateral breasts were cultured. After treatment with PDO-sensitive vinorelbine and carboplatin, partial response was achieved in the left compared with the initial tumor. Meanwhile, bilateral mastectomy was performed successfully, with pathological complete response achieved in the right. This typical case suggests that the PDOs from bilateral primary breast cancers can serve as a powerful tool to identify the sensitivity to NAC, thus providing novel treatment options at the patient-specific level.

期刊介绍: OncoTargets and Therapy is an international, peer-reviewed journal focusing on molecular aspects of cancer research, that is, the molecular diagnosis of and targeted molecular or precision therapy for all types of cancer. The journal is characterized by the rapid reporting of high-quality original research, basic science, reviews and evaluations, expert opinion and commentary that shed novel insight on a cancer or cancer subtype. Specific topics covered by the journal include: -Novel therapeutic targets and innovative agents -Novel therapeutic regimens for improved benefit and/or decreased side effects -Early stage clinical trials Further considerations when submitting to OncoTargets and Therapy: -Studies containing in vivo animal model data will be considered favorably. -Tissue microarray analyses will not be considered except in cases where they are supported by comprehensive biological studies involving multiple cell lines. -Biomarker association studies will be considered only when validated by comprehensive in vitro data and analysis of human tissue samples. -Studies utilizing publicly available data (e.g. GWAS/TCGA/GEO etc.) should add to the body of knowledge about a specific disease or relevant phenotype and must be validated using the authors’ own data through replication in an independent sample set and functional follow-up. -Bioinformatics studies must be validated using the authors’ own data through replication in an independent sample set and functional follow-up. -Single nucleotide polymorphism (SNP) studies will not be considered.
