Breast cancer study by UCR medical student could help patients live longer

(University of California - Riverside) A student at the University of California, Riverside, presented research results at the annual meeting of the American Association for Cancer Research, or AACR, in Atlanta showing that surgery is associated with higher survival rates for patients with HER2-positive stage 4 breast cancer compared with those who did not undergo surgery. The protein HER2, or human epidermal growth factor receptor 2, can play a role in the development of breast cancer.

Publication date: Available online 11 October 2019Source: Biosensors and BioelectronicsAuthor(s): Weiqing Xu, Lei Jiao, Huarong Ye, Zhenzhong Guo, Yu Wu, Hongye Yan, Wenling Gu, Dan Du, Yuehe Lin, Chengzhou ZhuAbstractEstrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2) are the three crucial biomarkers for the clinical diagnosis of breast cancer. Sensitive and precise detection of ER, PR, and HER2 is of great significance for the diagnosis of breast cancer. Herein, through a simple solvent-induced self-assembly process, the self-carried allochroic nanoparticles were prepar...

ConclusionThese results indicate that G-875A is a protective factor against BC, especially from luminal-A subtype, but may promote anaplasia in established tumors, consistent with TGF β signaling roles in BC.

ConclusionsThe present study demonstrates that, in plasma-derived exosomes, high  baseline CDK4 mRNA levels are associated with response to palbociclib plus hormonal therapy, while the increase in TK1 and CDK9 mRNA copies/ml is associated with clinical resistance.

Authors: Bae SJ, Ahn SG, Yoon CI, Yang BS, Lee HW, Son EJ, Jeong J Abstract Purpose: We evaluated the clinical value of breast magnetic resonance imaging (MRI) in patients who underwent breast-conserving surgery (BCS). The degree of correlation between pathology size and MRI or ultrasonography (US) size was compared based on breast cancer subtypes. In addition, we investigated the positive margin rates. Methods: Patients with invasive breast cancer who underwent preoperative breast MRI and US between 2011 and 2016 were included in the study. Lin's concordance correlation coefficient was used to measure the corr...

Conclusion: Changes in biomarker status are not rare, and usually occur in an unfavorable direction in breast cancer metastases. Negative conversion of ER status is a predictor of poor prognosis. Thus, it is beneficial to evaluate changes in biomarker status in MBC not only for the purpose of determining treatment options but also for prognostication of patients. PMID: 31598343 [PubMed]

Conclusion: Despite the low pCR rate, the tumor response and BCS conversion rates after NAC of luminal HER2- breast cancer were similar to those of other subtypes. NAC has the potential benefit of reducing the size of breast cancer, thereby increasing the BCS conversion rate in luminal HER2- breast cancer. PMID: 31598341 [PubMed]
