Cancer cells need constant supplies of lipids to survive and grow. Lipid dependence has been observed in various types of cancer, including high-grade serous ovarian carcinomas (HGSOC), which is a lethal form of gynecological malignancy. ANGPTL3, PCSK9, and Apo CIII are pivotal lipid-modulating factors, and therapeutic antibodies have been developed against each one (Evinacumab, Evolocumab and Volanesorsen, respectively).

Recent evidence suggests that genetic and epigenetic mechanisms might be associated with acquired resistance to cancer therapies. The aim of this study was to assess the association of genome-wide genetic and epigenetic alterations with the response to anti-HER2 agents in HER2-positive breast cancer patients. PubMed was screened for articles published until March 2021 on observational studies investigating the association of genome-wide genetic and epigenetic alterations, measured in breast cancer tissues or blood, with the response to targeted treatment in HER2-positive breast cancer patients.

Background / Synopsis: Cholesterol and lipids play an important role in sustaining tumor growth and metastasis in a large variety of cancers. ANGPTL3 and PCSK9 modify circulating cholesterol levels, thus availability of lipids to peripheral cells. Little is known on the role, if any, of circulating lipid-related factors such as PCSK9, ANGPTL3 and lipoprotein (a) in cancers.

Article Synopsis
  • * The study looked at how hospitals care for patients with insomnia and found that doctors often don't talk about sleep issues, usually giving medications instead.
  • * For better treatment, using a web-based therapy called CBT-I could work, but it needs training for staff and support to succeed in hospitals.

Article Synopsis
  • The NSABP B-36 trial compared the effectiveness of 6 cycles of epirubicin-based chemotherapy (FEC-100) to 4 cycles of doxorubicin-based chemotherapy (AC) in women with node-negative invasive breast cancer.
  • Results showed no significant improvement in disease-free survival (DFS) with FEC-100 over AC, despite higher toxicity reported in the FEC-100 group.
  • Additionally, the treatment's effectiveness varied by hormone receptor status, with FEC-100 performing better in receptor-positive patients, but overall, the findings do not support using prolonged anthracycline regimens for this patient group.

Background: Daily adjuvant endocrine therapy (AET) for 5 or 10 years is the standard of care for women diagnosed with non-metastatic hormone receptor-positive breast cancer. However, many women experience AET-related issues that may hamper quality of life and adherence. Here, we aimed to describe women's perceptions of motivational interviewing (MI)-guided consultations delivered by a trained nurse navigator over the telephone to enhance AET adherence.

As most erb-b2 receptor tyrosine kinase 2 (HER2)-positive breast cancer (BC) patients currently receive dual HER2-targeting added to neoadjuvant chemotherapy, improved methods for identifying individual response, and assisting postsurgical salvage therapy, are needed. Herein, we evaluated the 41-gene classifier trastuzumab advantage risk model (TRAR) as a predictive marker for patients enrolled in the NeoSphere trial. TRAR scores were computed from RNA of 350 pre- and 166 post-treatment tumor specimens.

Gene expression profiling tests such as the Oncotype DX (ODX) 21-gene recurrence score (RS) assay is increasingly used in clinical practice to predict the risk of recurrence and support treatment planning for early-stage breast cancer (BC). However, this test has some disadvantages such as a high cost and a long turnaround time to get results, which may lead to disparities in access. We aim to identify clinicopathological factors associated with ODX RS in women with early-stage BC.

TBC1D9: An Important Modulator of Tumorigenesis in Breast Cancer.

Cancers (Basel)

July 2021

Département de Médecine Moléculaire, Faculté de Médecine, Université Laval, Québec City, QC G1T 1C2, Canada.

Triple-negative breast cancer (TNBC) is a major concern among the different subtypes of breast cancer (BC) due to the lack of effective treatment. In a previous study by our group aimed at understanding the difference between TNBC and non-TNBC tumors, we identified the gene TBC1 domain family member 9 (), the expression of which was lower in TNBC as compared to non-TNBC tumors. In the present study, analysis of TBC1D9 expression in TNBC ( = 58) and non-TNBC ( = 25) patient tumor samples validated that TBC1D9 expression can differentiate TNBC (low) from non-TNBC (high) samples and that expression of TBC1D9 was inversely correlated with grade and proliferative index.

Is Carboxypeptidase B1 a Prognostic Marker for Ductal Carcinoma In Situ?

Cancers (Basel)

April 2021

Département de Médecine Moléculaire, Faculté de Médecine, Université Laval, Québec City, QC G1T 1C2, Canada.

Ductal carcinoma in situ (DCIS) is considered a non-obligatory precursor for invasive ductal carcinoma (IDC). Around 70% of women with atypical ductal hyperplasia (ADH) undergo unnecessary surgery due to the difficulty in differentiating ADH from low-grade DCIS. If untreated, 14-60% of DCIS progress to IDC, highlighting the importance of identifying a DCIS gene signature.
