Induction of the TEAD Coactivator VGLL1 by Estrogen Receptor-Targeted Therapy Drives Resistance in Breast Cancer.

Resistance to endocrine therapies (ET) is common in estrogen receptor (ER)-positive breast cancer, and most relapsed patients die with ET-resistant disease. Although genetic mutations provide explanations for some relapses, mechanisms of resistance remain undefined in many cases. Drug-induced epigenetic reprogramming has been shown to provide possible routes to resistance.

The expression of high mobility group protein 3 () in breast cancer with emphasis on its role in lymphovascular invasion.

Lymphovascular invasion (LVI) is a common phenomenon in breast cancer (BC), and it is correlated to poor outcome. However, the biomarkers that influence the development of LVI remain to be defined. Through rigorous bioinformatics analyses, () was revealed as a driver gene that is associated with the presence of LVI.

Visual histological assessment of morphological features reflects the underlying molecular profile in invasive breast cancer: a morphomolecular study.

Aims: Tumour genotype and phenotype are related and can predict outcome. In this study, we hypothesised that the visual assessment of breast cancer (BC) morphological features can provide valuable insight into underlying molecular profiles.

Methods And Results: The Cancer Genome Atlas (TCGA) BC cohort was used (n = 743) and morphological features, including Nottingham grade and its components and nucleolar prominence, were assessed utilising whole-slide images (WSIs).

A novel prognostic two-gene signature for triple negative breast cancer.

The absence of a robust risk stratification tool for triple negative breast cancer (TNBC) underlies imprecise and nonselective treatment of these patients with cytotoxic chemotherapy. This study aimed to interrogate transcriptomes of TNBC resected samples using next generation sequencing to identify novel biomarkers associated with disease outcomes. A subset of cases (n = 112) from a large, well-characterized cohort of primary TNBC (n = 333) were subjected to RNA-sequencing.

Recurrent mandibular ameloblastoma in soft tissue and rib graft 17 years after initial presentation.

Background: Ameloblastoma is the commonest odontogenic tumour of epithelial origin with a high incidence for developing local recurrence. We present a patient who developed local recurrence in both soft tissue and bone graft 17 years after the initial presentation.

Case Presentation: A 75-year-old female with a previous history of right hemimandibulectomy and rib reconstruction for ameloblastoma in 1999 presented to our centre with a large cystic mouth floor swelling, biopsy from which revealed recurrent ameloblastoma.

Prognostic significance of nucleolar assessment in invasive breast cancer.

Aims: Nucleolar morphometric features have a potential role in the assessment of the aggressiveness of many cancers. However, the role of nucleoli in invasive breast cancer (BC) is still unclear. The aims of this study were to investigate the optimal method for scoring nucleoli in IBC and their prognostic significance, and to refine the grading of breast cancer (BC) by incorporating nucleolar score.

Prognostic significance of KN motif and ankyrin repeat domains 1 (KANK1) in invasive breast cancer.

Background: KN motif and ankyrin repeat domains 1 (KANK1) plays an important role in cytoskeleton maintenance and contributes to the regulation of cell proliferation, adhesion and apoptosis. KANK1 is involved in progression of a variety of solid tumours; however, its role in invasive breast cancer (BC) remains unknown. This study aims to evaluate the clinicopathological and prognostic value of KANK1 expression in operable BC.

Male Breast Huge Malignant Phyllodes.

Phyllodes tumors are rare breast tumors. The best treatment is wide local excision with 1 cm safety margin unless metastatic. The three pathological types (benign, borderline and malignant were reported in men.

A key genomic subtype associated with lymphovascular invasion in invasive breast cancer.

Background: Lymphovascular invasion (LVI) is associated with the development of metastasis in invasive breast cancer (BC). However, the complex molecular mechanisms of LVI, which overlap with other oncogenic pathways, remain unclear. This study, using available large transcriptomic datasets, aims to identify genes associated with LVI in early-stage BC patients.

Small breast Schwannoma in an old female; a case report.

Schwannoma is a usually benign peripheral nerve sheath tumor with rare breast incidence and few reported cases. We report a case which was presented to and managed in the Oncology center, Mansoura University in November 2017.

Utility of ankyrin 3 as a prognostic marker in androgen-receptor-positive breast cancer.

Purpose: Androgen receptor (AR) and AR signaling pathways are thought to play a role in breast cancer (BC) and are potentially related to treatment responses and outcomes. Ankyrin 3 (ANK3) is associated with AR stability in cancer cells. In the present study, we investigated the clinicopathological utility of ANK3 expression with emphasis on AR and its associated signalling pathway at transcriptomic and proteomic phases.

A Totally Laparoendoscopic Approach for Low Rectal Cancer with Inguinal Nodal Metastasis.

Background And Aims: Isolated inguinal nodal metastasis from rectal cancer is rare with better oncological outcome in case of surgical resection.

Methods: We report a rectal cancer case with inguinal nodal metastasis that was operated using a totally endoscopic approach. Laparoscopic intersphincteric resection was done for rectal cancer and video endoscopic inguinal lymphadenectomy (VEIL) for inguinal lymph nodes.
