Extra-gain of HER2
Positive cases through HER2 reassessment in primary and metastatic sites in advanced gastric cancer with initially HER2-negative primary tumours: Results of GASTric cancer HER2 reassessment study 1 (GASTHER1)
MicroRNA expression profiling identifies decreased expression of miR-205 in inflammatory breast cancer
Inflammatory breast cancer is the most aggressive form of breast cancer. Identifying new biomarkers to be used as therapeutic targets is in urgent need. Messenger RNA expression profiling studies have indicated that inflammatory breast cancer is a transcriptionally heterogeneous disease, and specific molecular targets for inflammatory breast cancer have not been well established. We performed microRNA expression profiling in inflammatory breast cancer in comparison with locally advanced noninflammatory breast cancer in this study. Although many microRNAs were differentially expressed between…
Digital image analysis outperforms manual biomarker assessment in breast cancer
In the spectrum of breast cancers, categorization according to the four gene expression-based subtypes ‘Luminal A,’ ‘Luminal B,’ ‘HER2-enriched,’ and ‘Basal-like’ is the method of choice for prognostic and predictive value. As gene expression assays are not yet universally available, routine immunohistochemical stains act as surrogate markers for these subtypes. Thus, congruence of surrogate markers and gene expression tests is of utmost importance. In this study, 3 cohorts of primary breast cancer specimens (total n = 436) with up to…
