COX2 protein levels and nuclear COX2 expression were correlated with a poor prognosis of CRC patients. COX2 expression was positively associated with HER2 expression. PMID: 29873317
3. In patients with HER2-positive advanced breast cancer who have been heavily pretreated with anti-HER2 agents and cytotoxic chemotherapy, trastuzumab emtansine (T-DM1) is well tolerated and provided a meaningful progression-free survival of 6 months and an overall survival that has not been reached. PMID: 29326401

5. Although ST6GalI overexpression increased HER2 sialylation, corresponding to decreased HER2 phosphorylation, high alpha2,6sialylation enhanced Akt and ERK phosphorylation levels compared to those in the vector cell line; ST6GalI knockdown had the opposite effects.

7. In early breast cancer, PIK3CA mutations seem to identify HER2+ patients who are less likely to reach pCR. The clinical implications of PIK3CA mutations tend to vary between exon 9 and exon 20. This mechanism should be explored in further studies. PMID: 29575819
8. HER2 and HER3 expression was detected in 22.2% and 86.1% of samples, respectively. The frequency of EGFR mutation was 45.7% and was not significantly different between stage 0 and IA1 (40.0% and 48.0%, respectively), suggesting that EGFR mutation does not correlate with cancer progression from stage 0 to IA1.

13. The combination of immunohistochemical expression of BRCA1, ER, PR, and HER-2/neu and clinicopathological details may be helpful in predicting the individuals more likely to carry BRCA1 mutations and thus selecting the candidate and family members for genetic screening for BRCA1 mutations. PMID: 29567881
14. In the current settings, HER2/neu is not found to be a prognostic marker in head-and-neck cancers. PMID: 30004046

24. The Authors reveal a gender difference in the prognostic value of concomitant AIB1 and HER2 copy number gain (CNG) in glioma patients which were barely noticed before. These observations indicated that genetic alterations synergistic with essential respects of sex determination influence glioma biology and patients outcomes. PMID: 30153912
25. The survival rates in this study are equal to the documented global rates; nodal disease burden emerged as the most important prognostic factor. In addition, in EBCs, a lack of hormone receptor expression and in LABC, Her2neu overexpression appear to worsen the outcome. PMID: 30147088

33. In the largest series reported to date, patients with HER2-amplified m17 cancers treated with trastuzumab have outcomes comparable to patients from the large phase III adjuvant trastuzumab trials who were HER2-positive, supporting the critical role of HER2-directed therapy in this patient population. PMID: 28986743

35. Study provides evidence that the hostile environment developed in spheroids has a key role in the acquisition of resistance to Trastuzumab and is associated with an increase in the number of breast cancer stem cells as well as a modulation in HER2 expression. PMID: 28722778
36. A major finding of our study is that one out of five (20%) patients with breast cancer BM had a receptor discrepancy between the primary tumor and the subsequent BM, with loss of hormone receptors (ER and/or PR) expression, and gain of HER2 overexpression as the most commonly observed changes PMID: 28975433
