ConclusionsNeoadjuvant versus adjuvant with standard anthracycline- and taxane-containing regimens results in similar disease-free survival and overall survival among patients with stage I and II triple-negative breast cancer regardless of BRCA status. Further studies are needed to evaluate whether similar results are observed with newer agents.

ConclusionAlthough the study was terminated owing to the altered liver function, it showed that there was a trend to greater shrinkage of tumor in the combination group for ER-positive, HER2-negative postmenopausal breast cancer.

ConclusionThe presence of microcalcifications on imaging and DCIS on initial CNB are associated with residual disease after neoadjuvant chemotherapy in TNBC. These variables can aid in identifying patients with TNBC suitable for inclusion in trials evaluating non‐surgical management after neoadjuvant chemotherapy.

Chemotherapy-induced peripheral neuropathy (CIPN) is a frequent adverse reaction caused by chemotherapeutic agents, especially the taxanes. CIPN can persist from months to years after completion of chemotherapy, decreasing quality of life for cancer survivors. The aim of this study was to explore the incidence and risk factors of persistent CIPN among women with breast cancer receiving neoadjuvant chemotherapy.

CONCLUSIONS: we identified capecitabine as efficient chemotherapy in TNBC PDX models established from residual disease and resistant to anthracyclines, taxanes and platins. RB positivity and high expression of TYMP were significantly associated with capecitabine response. PMID: 29463559 [PubMed - as supplied by publisher]

We report the largest series of IMCs treated with NAC, and report a characteristic, but not well recognised, pattern of pathological response. Methods and resultsOur series included seven patients with IMC treated with NAC. Three patients presented with locally advanced disease, three patients had tumours that were HER‐2/neu‐positive, and four patients had tumours with admixed mucinous and micropapillary features. Clinical and imaging assessment of response showed persistent and, in some cases, progressive disease, despite evidence of significant pathological response in these cases. Pathological assessment after NAC d...

CONCLUSIONS: This study confirmed the therapeutic impact of lapatinib, trastuzumab, and paclitaxel therapy for each ER- and ER+ subgroup of HER2+ patients. Development of further strategies and tools is required, particularly for luminal HER2 disease. PMID: 29445928 [PubMed - as supplied by publisher]

ConclusionPatients that achieved a pCR appeared less likely to present with skeletal metastases and more frequently presented with CNS metastases as first site of distant relapse, even after adjustment for molecular subtypes.

ConclusionsBoth CTCs and DTCs are detectable after NACT. As we could not show a significant relationship between CTC detection, DTC detection and pCR, all three methods may provide independent information regarding treatment response. Since we were unable to show a significant impact on survival, larger prospective studies that include CTCs and DTCs are needed. These trials should include the molecular characterization of primary tumor tissue, CTCs and DTCs to determine whether these cells are independent subpopulations of malignant cell clones.
