Indentification of breast cancer subtypes sensitive to HCQ-induced autophagy inhibition

ConclusionTo conclude, basal-like breast cancer represented by SUM-190 cells may be most sensitive to HCQ induced autophagy inhibition and the mechanism might be relative to Ras/Raf/ERK signaling pathway.

Authors: Yu F, Wang L, Zhang B Abstract Long non-coding RNA (lncRNA) downregulated in hepatocellular carcinoma (DRHC) is a tumor suppressor in liver cancer. However, the role of this lncRNA in breast cancer has not been investigated. The present study revealed that lncRNA DRHC was downregulated and lncRNA Hox transcript antisense RNA (HOTAIR) was upregulated in tumor tissues compared with adjacent healthy tissues in patients with triple negative breast cancer (TNBC). Expression levels of lncRNA DRHC and lncRNA HOTAIR were negatively correlated in tumor tissues but not in adjacent healthy tissues. The lncRNA DRHC ex...

AbstractPurposeNuclear grade is an important indicator of the biological behaviour of ductal carcinoma in situ (DCIS). De-escalation of treatment has been suggested for low-grade DCIS. Our aim is to estimate the relative rate of progression of DCIS by nuclear grade by analysing the distribution of nuclear grade by detection at initial or subsequent screening.MethodsWe asked International Cancer Screening Network sites to complete, based on their screening and clinical databases, an aggregated data file on DCIS detection, diagnosis and treatment.ResultsEleven screening programs reported 5068 screen-detected pure DCIS in nea...

ConclusionsThere is modest correlation in continuous gene expression, as measured by the RS and single-gene results for ER, PR, and HER2 between paired primary tumors and synchronous nodal metastases. RS testing for ER+ breast cancer should continue to be based on analysis of primary tumors.

Conclusion High values of AUC, sensitivity, specificity, NPV and PPV encourage utilization of PET/CT for locoregional staging of nonmetastatic breast carcinoma. The significant correlation between the primary tumor SUVmax value and grade, ER status, PR status and Ki-67 level increases the prognostic predictive value of the preoperative PET/CT.

Objective To evaluate metabolic and volume-based parameters of 18-Fluorodeoxyglucose positron emission tomography/computed tomography ((18F)FDG PET/CT) for primary mass and axillary lymph node (ALN) metastasis in relation to molecular subtype, and immunohistochemistry and inflammatory markers in patients with invasive ductal carcinoma. Methods A total of 129 patients (mean±SD age: 49.2±13.0 years) with invasive ductal breast cancer who had (18F)FDG PET/CT imaging prior to chemotherapy or surgery were included in this single-center retrospective study. Data on patient age, molecular subtype, ALN metastasi...

ConclusionsThe combination of belinostat 2000  mg/m2 days 1 –5 and 13-cRA 100 mg/m2 days 1 –14, every 21 days, was well-tolerated and an MTD was not reached despite doubling the established single-agent MTD of belinostat.

CONCLUSIONS In brief, the withaferin-A molecule has great potential as an anticancer agent against drug-resistant breast cancer, and as such needs to be further studied in detail. PMID: 31512681 [PubMed - in process]
