Differential gene expression and AKT targeting in triple negative breast cancer.

Conclusion: Genomic discordance of paired primary and metastatic TNBCs was identified, with significant increase in tumor proliferation pathways seen in metastases. Among the differentially expressed genes, AKT3 can potentially serve as a target for novel combination therapy for treatment of metastatic TNBC. Methods: Paired specimens from 10 patients with TNBCs were identified through an IRB-approved protocol (2002-2015). FoundationOneTM sequencing was performed for genomic profiling, and Affymetrix Human Genechip 2.0st was used for mRNA expression profiling. The similarity among samples was calculated based on Pearson correlation coefficients, which were used to construct hierarchical clustering and heat maps. PMID: 31320990 [PubMed]

Background: Persistent hair disorders resulting from cytotoxic or endocrine agents used in early stages of breast cancer such as alopecia, hirsutism, and madarosis develop in 4-35% of patients, however their impact on quality of life (QoL) has not been reported. The CHANCE study is a prospective, longitudinal study of chemotherapy- and endocrine therapy-induced hair, skin, and nail changes in women with nonmetastatic breast cancer. This preliminary analysis intends to evaluate the impact of permanent hair sequelae of adjuvant breast cancer therapies on patients ’ QoL.

Abstract PURPOSE: To evaluate the use of individualized piano instruction (IPI) for improving cognition among breast cancer survivors. PARTICIPANTS & SETTING: Six participants were included in an eight-week piano program with three data collection time points at baseline, midpoint, and postintervention. Participants were recruited from the breast cancer clinic of a university cancer center in South Florida. METHODOLOGIC APPROACH: Neurocognitive, psychosocial, and self-report assessments were conducted to determine potential benefits and program feasibility, including the NIH Toolbox® Cognition Ba...

Abstract PROBLEM IDENTIFICATION: This review identifies specific cardiotoxicity related to anthracycline chemotherapy, specific risk factors related to increased anthracycline chemotherapy-induced cardiotoxicity, and underlying mechanisms of action of anthracycline chemotherapy-induced cardiotoxicity. LITERATURE SEARCH: PubMed®, CINAHL®, Embase®, and Web of Science were searched in May 2018 using keywords related to heart diseases, anthracycline chemotherapy, and breast cancer. DATA EVALUATION: Data were extracted, and study quality was assessed according to PRISMA (Preferred Reporting Items ...

Metastable phenotypic state transitions in cancer cells can lead to the development of transient adaptive resistance or tolerance to chemotherapy. Here, we report that the acquisition of a phenotype marked by increased abundance of CD44 (CD44Hi) by breast cancer cells as a tolerance response to routinely used cytotoxic drugs, such as taxanes, activated a metabolic switch that conferred tolerance against unrelated standard-of-care chemotherapeutic agents, such as anthracyclines. We characterized the sequence of molecular events that connected the induced CD44Hi phenotype to increased activity of both the glycolytic and oxid...

CONCLUSIONS: The most potential impact of TAILORx findings on practice change is for patients ≤ 50 years of age with RS of 16-25 who did not receive chemotherapy but may benefit. These findings may serve as a baseline for future analysis of practice patterns related to TAILORx. PMID: 31429016 [PubMed - as supplied by publisher]

In conclusion, our data show how oncogenic and tumor-suppressive drivers of cellular senescence act to regulate surveillance processes that can be circumvented to enable SnCs to elude immune recognition but can be reversed by cell surface-targeted interventions to purge the SnCs that persist in vitro and in patients. Since eliminating SnCs can prevent tumor progression, delay the onset of degenerative diseases, and restore fitness; since NKG2D-Ls are not widely expressed in healthy human tissues and NKG2D-L shedding is an evasion mechanism also employed by tumor cells; and since increasing numbers of B cells express NKG2D ...
