Comprehensive molecular biomarker identification in breast cancer brain metastases.

Background: Breast cancer brain metastases (BCBM) develop in about 20-30% of breast cancer (BC) patients. BCBM are associated with dismal prognosis not at least due to lack of valuable molecular therapeutic targets. The aim of the study was to identify new molecular biomarkers and targets in BCBM by using complementary state-of-the-art techniques.

Low expression of leptin and its association with breast cancer: A transcriptomic study.

The incidence of breast cancer is alarmingly increasing worldwide and also among Saudi women. Obesity is linked with an increased cancer risk and studies have also revealed that leptin may be involved in breast tumorigenesis particularly among obese women. Numerous transcriptomic studies have been carried out worldwide; however, molecular studies among breast cancer patients of diverse ethnic groups from the Arabian Peninsula are scarce.

Frequent methylation of the KLOTHO gene and overexpression of the FGFR4 receptor in invasive ductal carcinoma of the breast.

Invasive ductal carcinoma of the breast is the most common cancer affecting women worldwide. The marked heterogeneity of breast cancer is matched only with the heterogeneity in its associated or causative factors. Breast cancer in Saudi Arabia is apparently an early onset with many of the affected females diagnosed before they reach the age of 50 years.

Characterization of familial breast cancer in Saudi Arabia.

Background: The contribution of genetic factors to the development of breast cancer in the admixed and consanguineous population of the western region of Saudi Arabia is thought to be significant as the disease is early onset. The current protocols of continuous clinical follow-up of relatives of such patients are costly and cause a burden on the usually over-stretched medical resources. Discovering the significant contribution of BRCA1/2 mutations to breast cancer susceptibility allowed for the design of genetic tests that allows the medical practitioner to focus the care for those who need it most.

Transcriptomics profiling study of breast cancer from Kingdom of Saudi Arabia revealed altered expression of Adiponectin and Fatty Acid Binding Protein4: Is lipid metabolism associated with breast cancer?

Background: Breast cancer incidence rates are increasing at an alarming rate among Saudi Arabian females. Most molecular genetic discoveries on breast cancer and other cancers have arisen from studies examining European and American patients. However, possibility of specific changes in molecular signature among cancer patients of diverse ethnic groups remains largely unexplored.

Management of postoperative gastrointestinal leakage with autologous stromal vascular fraction.

To assess the efficacy of using autologous stromal vascular fraction (SVF) to promote healing of controlled fistula tracts in the management of postoperative upper gastrointestinal leakage. This is an experimental study conducted on 10 experimental rabbits. Animal models were divided into the SVF group which received an autologous SVF and the control group which did not receive the implantation.

The desire to utilize postmastectomy breast reconstruction in Saudi Arabian women. Predictors and barriers.

Objectives: To study factors that influence the desire to utilize breast reconstruction after mastectomy, and to investigate the barriers to reconstruction among women in Saudi Arabia.

Methods: We conducted a cross-sectional study at 2 surgical centers in Jeddah, Saudi Arabia. A self-administered questionnaire was distributed to all breast cancer patients attending the surgery clinics for follow-up after mastectomy between January and March 2013.

Primary mucosa-associated lymphoid tissue lymphoma of the esophagus masquerading as a benign tumor.

We report a case of primary esophageal low-grade B-cell lymphoma of MALT type in a 50-year-old Saudi male patient who presented to our hospital with a history of dysphagia and heartburn for more than 2 years. Endoscopy showed a large esophageal mass with an intact mucosa located in the distal esophagus, 28 cm-35 cm from the incisor teeth. Endoscopic ultrasonography (EUS) showed a large well demarcated sub-epithelial lesion 4 cm in width and 10 cm in length arising from the muscularis mucosa with mixed echogenicity consistent with benign leiomyoma.

Expression of matrix metalloproteinases (MMPs) in primary human breast cancer: MMP-9 as a potential biomarker for cancer invasion and metastasis.

Background/aim: Breast cancer (BC) is the most common type of cancer in Saudi women. Matrix metalloproteinases (MMPs) are endopeptidases with the ability to degrade extracellular matrix proteins. In healthy individual tissue disruption is prevented by precised regulation of MMPs; however, in cancer a number of MMPs are overexpressed causing tissue disruption and making tumor cells capable of invasion and metastasis.

Phase II study on the use of intraoperative radiotherapy in early breast cancer.

Objective: To report our early experience using the Intrabeam radiotherapy delivery system for intraoperative radiotherapy (IORT) in early breast cancer.

Methods: This is a prospective phase 2 study carried out at the Department of Surgery and Radiology, King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi Arabia from December 2010 to November 2012. Females eligible for breast-conserving surgery with biopsy-proven invasive duct carcinoma, and with a mass of View Article and Find Full Text PDF

High fibroblast growth factor 19 (FGF19) expression predicts worse prognosis in invasive ductal carcinoma of breast.

Metabolic diseases like diabetes and obesity are major risk factors for breast cancer. Aberrant expression of metabolic effectors such as fibroblast growth factor 19 (FGF19) could be therefore associated with the disease. The expression of FGF19 was examined in 193 archival breast tumor samples by immunohistochemistry and evaluated semi-quantitatively by determining the staining index and correlating it with clinicopathological parameters using Fisher's exact test.

RASSF1A methylation is predictive of poor prognosis in female breast cancer in a background of overall low methylation frequency.

Breast cancer (BC) is the most common cancer worldwide. The Kingdom of Saudi Arabia is no exception, with ever increasing incidence rates. An interesting feature of this disease is the relatively young age of the affected women.

Prognostic value of mitotic counts in breast cancer of Saudi Arabian patients.

Background: Quantitative methods in combination with other objective prognostic criteria can improve the evaluation of a cancer patient's prognosis, and possibly predict response to therapy. One of the important prognostic and predictive markers is the mitotic count, which has proven valuable in many aspects. In this study, the prognostic value of the mitotic count was assessed in breast cancer (BC) patients in Saudi Arabia.

Nuclear morphometry in prognostication of breast cancer in Saudi Arabian patients: comparison with European and African breast cancer.

Background: The role of nuclear morphometry as a prognostic factor in breast cancer is well documented. The aim of this study was to evaluate this role in breast cancer in Saudi patients and to compare it with the experience in some African and European studies.

Patients And Methods: Primary tumors from 135 patients were analyzed using an image overlay drawing system (Prodit Morphometry Program), for the following nuclear features: area, perimeter, diameter, and roundness.
