Integrating PARP inhibitors into the management of breast cancer: where are we?

During the last 2 decades, extensive research has focused on the molecular functions of BRCA1 and BRCA2 genes. This has led to the development of Poly(ADP-ribose) polymerase inhibitors (PARPi), as effective target therapies, based on their preferential cytotoxicity in tumor cells harboring germline BRCA1 and BRCA2 mutations. At the present time, 2 PARPi (Olaparib and Talazoparib) are approved as single agent for the treatment of patients with metastatic HER2-ve breast cancer, who have BRCA germline mutations.

Adjuvant ovarian function suppression and tamoxifen in premenopausal breast cancer patients: A meta-analysis.

Background: The benefit of adding ovarian function suppression (OFS) to tamoxifen in the adjuvant treatment of premenopausal women with breast cancer is uncertain. We conducted a meta-analysis of randomized controlled trials that addressed this question.

Methods: Systematic search of PubMed, the web of science, and the meeting library of ASCO, ESMO, and SABCS was conducted using the following keywords: tamoxifen, ovarian suppression, and breast cancer.

Personalized treatment in metastatic triple-negative breast cancer: The outlook in 2020.

Compared with other breast cancer subtypes, patients with triple-negative breast cancer (TNBC), and irrespective to their disease stage, were always recognized to have the worst overall survival data. Although this does not seem different at the present time, yet the last few years have witnessed many breakthrough genomic and molecular findings, that could dramatically improve our understanding of the biological complexity of TNBC. Based on genomic analyses, it was consistently evident that TNBC comprises a heterogeneous group of cancers, which have numerous diverse molecular aberrations.

Understanding the benefits and challenges of first-line cyclin-dependent kinases 4 and 6 inhibitors in advanced breast cancer among postmenopausal women.

Endocrine therapy (ET) has been regarded for many years as the standard treatment for patients with hormone receptor-positive (ER+), HER2-negative (HER2-) advanced breast cancer (ABC) without visceral crisis. However, the efficacy of single-agent ET is constrained by the development of resistance, attributed to alterations in several intracellular signaling pathways, including those related to cell cycle dysregulation. The cyclin-dependent kinases 4 and 6 (CDK4/6) are principal regulators of cell cycle progression from the G1-phase into the DNA synthesis (S)-phase.

Analysis of PI3K/mTOR Pathway Biomarkers and Their Prognostic Value in Women with Hormone Receptor-Positive, HER2-Negative Early Breast Cancer.

Background: The PI3K/AKT/mTOR pathway alterations have been shown to play significant roles in the development, progression, and metastatic spread of breast cancer. Furthermore, they have been implicated in the process of drug resistance, especially endocrinal therapies. In this study, we aimed to define the correlation between the PI3K mutations and the expression of the phosphorylated forms of different downstream molecules in women with estrogen receptor (ER)-positive, human epidermal growth factor receptor 2-negative (luminal) early breast cancer treated at Cairo university hospitals.

TNMF versus TNM in staging of colorectal cancer.

Aim: TNM staging and histological grading of rectal cancer has undergone no or minimal changes during the past 20 years despite their major impact on planning, reporting and outcome of the disease. The addition of category 'F' to the 'TNM' staging of colorectal cancer, which becomes TNMF will accommodate the expanding list of risk factors that may affect the management and thus avoid squeezing them into the TNM categories.

Methods: Reporting of the following risk factors was traced in 730 (664 retrospective and 66 prospective) cases of colorectal cancer: age, Tumor location, preoperative CEA, intraoperative tumor perforation and blood transfusion, quality of TME, tumor grade, non nodal T.
