BackgroundBreast cancer patients are increasingly seeking Complementary and Alternative Medicine (CAM) therapies with the hope of alleviating the burden of the disease and improving their quality of life (QOL). The objective of this study was to assess the prevalence, types, socio-demographic and disease-related correlates as well as characteristics of CAM use (including disclosure to treating physicians) among breast cancer patients in Beirut, Lebanon. A secondary objective was to evaluate the association between CAM use and QOL.MethodsA cross-sectional survey was conducted on breast cancer patients recruited from two major referral centers in Beirut: a philanthropic hospital and a private academic medical center. In face-to-face interviews, participants completed a questionnaire of three sections: socio-demographic and lifestyle characteristics, breast cancer condition, and CAM use. Three to four weeks following these interviews, the secondary QOL assessment was carried out via telephone using the Arabic version of the Functional Assessment of Cancer Therapy-Breast questionnaire. The main outcome in this study, CAM use, was defined as using CAM at least once after breast cancer diagnosis.ResultsA total of 180 breast cancer patients completed the survey (response rate: 94.6 %). Prevalence of CAM use was 40 %. Using multivariate logistic regression, CAM use was negatively associated with age (OR: 0.96, CI: 0.92-0.99), treatment at the philanthropic hospital (OR: 0.13, CI: 0.05-0.35) and was positively associated with an advanced stage of the disease (OR: 4.20, CI: 1.65-10.69). Among study participants recruited from both sites, the most commonly used CAM was ‘special food’ followed by ‘herbal teas’, ‘diet supplements’ and ‘Spiritual healing’. Only 4 % of CAM users cited health professionals as influencing their choice of CAM and only one in four patients disclosed CAM use to their treating physician. There was no significant association between CAM use and QOL.ConclusionsThe findings of this study revealed a prevalent CAM use among Lebanese breast cancer patients. Furthermore, physicians’ role in orienting CAM use was found to be marginal as patients relied mainly on family and media for their choice of CAM and were less likely to disclose CAM use to their treating physicians.Electronic supplementary materialThe online version of this article (doi:10.1186/s12906-015-0969-9) contains supplementary material, which is available to authorized users.
Breast cancer is commonest cancer in women worldwide. Elucidation of underlying biology and molecular pathways is necessary for improving therapeutic options and clinical outcomes. Molecular alterations in breast cancer are complex and involve cross-talk between multiple signaling pathways. The aim of this study is to extract a unique mRNA fingerprint of breast cancer in Lebanese women using microarray technologies. Gene-expression profiles of 94 fresh breast tissue samples (84 cancerous/10 non-tumor adjacent samples) were analyzed using GeneChip Human Genome U133 Plus 2.0 arrays. Quantitative real-time PCR was employed to validate candidate genes. Differentially expressed genes between breast cancer and non-tumor tissues were screened. Significant differences in gene expression were established for COL11A1/COL10A1/MMP1/COL6A6/DLK1/S100P/CXCL11/SOX11/LEP/ADIPOQ/OXTR/FOSL1/ACSBG1 and C21orf37. Pathways/diseases representing these genes were retrieved and linked using PANTHER®/Pathway Studio®. Many of the deregulated genes are associated with extracellular matrix, inflammation, angiogenesis, metastasis, differentiation, cell proliferation and tumorigenesis. Characteristics of breast cancers in Lebanese were compared to those of women from Western populations to explain why breast cancer is more aggressive and presents a decade earlier in Lebanese victims. Delineating molecular mechanisms of breast cancer in Lebanese women led to key genes which could serve as potential biomarkers and/or novel drug targets for breast cancer.
BackgroundAnthracycline adjuvant therapy has taken a particular role in the treatment of early stage breast cancer with an associated decrease in rates of both relapse and death. Their success however has been limited by their myelosuppression and their well-established risk of cardiac dysfunction. Guidelines have emerged that would limit the maximum lifetime dose of anthracyclines and make a baseline assessment and periodic monitoring of cardiac function part of the routine practice, which could be cumbersome, and may condemn the patient to an unwarranted modification of his/her regimen. Our study aimed at assessing the incidence of abnormal baseline echocardiography in asymptomatic women with breast cancer prior to anthracycline therapy and establishing risk criteria associated with abnormal echocardiograms at baseline.Methods220 Patients seen at AUBMC (American University of Beirut Medical Center) who had non- metastatic breast cancer, and had an echocardiography performed before starting anthracycline chemotherapy were chosen. Data about demographic characteristics, tumor characteristics, baseline echocardiography results, and change in clinical decision was collected. Patients with suboptimal (less than 50%) ejection fraction (EF) on baseline echocardiography were analyzed for the prevalence of cardiac risk factors. Results were compared to those among the overall study group using Fisher’s Exact test. A p- value of = < 0.05 was used as reference for statistical significance.ResultsAll 220 of our patients had received a baseline echo prior to initiation of anthracycline therapy. 6.7% of these patients had already some abnormality in wall motion but only 2.7% had a suboptimal ejection fraction. 1.3% had a change in chemotherapy regimen based on ejection fraction. The patients with depressed EF had higher rates of CAD (coronary artery disease), diabetes, hypertension and dyslipidemia than the overall study group but without statistical significance.ConclusionsOur study, as well as the previous contingent studies raise the question about routine echocardiography prior to anthracycline therapy and might eventually lead to a modification of current practice guidelines.
