Consumption of Food Components of the Mediterranean Diet Decreases the Risk of Breast Cancer in the Makkah Region, Saudi Arabia: A Case-Control Study. Front Nutr 2022; 9:863029. [PMID: 35614977 PMCID: PMC9125785 DOI: 10.3389/fnut.2022.863029] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Accepted: 03/14/2022] [Indexed: 11/25/2022] Open
Abstract
Background Breast cancer is one of the leading causes of death worldwide, it affects both men and women. In Saudi Arabia, breast cancer has been the most prevalent type of cancer in women, for the past few years. Dietary habits and cultural beliefs vary according to region, and further studies are required to demonstrate the relationship between these dietary habits and cultural beliefs and the risk of developing breast cancer. This study is aimed to discover the relationship between preventive dietary factors of the Mediterranean diet and rates of breast cancer among postmenopausal women in the Makkah region of Saudi Arabia. Methods A case-control study was conducted in King Abdulla Medical City Hospital, Makkah, Saudi Arabia and included 432 Saudi female participants: 218 in the control group and 214 breast cancer patients. All participants were postmenopausal, around the same age, and all were ethnically Arab Saudis. Data were obtained using a self-administered validated questionnaire. Results Study results showed that a diet that includes 1-2 servings of legumes weekly, 1-5 servings of fish weekly, 1-5 servings of dairy products daily, 3-5 servings of fruits and vegetables daily, and more than one cup of black tea and coffee per day significantly (p < 0.05) reduces the risk of breast cancer. Conclusion This study demonstrates that consuming a Mediterranean diet, which includes legumes, fish, fruits and vegetables, black tea, coffee, and low intake of dairy products, works as a preventive factor against breast cancer in postmenopausal females from the Makkah region.

Voutsadakis IA. Vitamin D baseline levels at diagnosis of breast cancer: A systematic review and meta-analysis. Hematol Oncol Stem Cell Ther 2020; 14:16-26. [PMID: 33002425 DOI: 10.1016/j.hemonc.2020.08.005] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2020] [Revised: 07/17/2020] [Accepted: 08/14/2020] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Vitamin D is a steroid hormone that exerts its actions through ligation of the vitamin D receptor (VDR), a transcription factor of the nuclear receptor family. VDR has not only physiologic actions in calcium metabolism but also several other cellular effects through extensive binding to the DNA and modification of genome expression. In cancer, it has neoplasia-suppressive effects and various mechanisms of action mediating cancer cell inhibition have been described. Vitamin D deficiency has been linked to increased risk of breast cancer. A role of the vitamin once the disease has been diagnosed is also probable. METHODS A systematic review and meta-analysis of studies that report on vitamin D levels (in the form of its main circulating metabolite, 25-hydroxyvitamin D [25-OHD]) in patients with newly diagnosed breast cancer was performed. Outcomes of interest included the levels of serum 25-OHD in patients with breast cancer, those of matched controlled, in studies that included controls, as well as respective percentages of patients and controls with deficient and insufficient 25-OHD levels. RESULTS A total of 25 studies (10 with controls and 15 without controls) provided data on the outcomes of interest. Populations from all continents, besides Australia, were represented in the studies. The mean level of 25-OHD in patients with breast cancer was 26.88 ng/mL (95% CI 22.8-30.96 ng/mL) and the mean level of 25-OHD in control patients was 31.41 ng/mL (95% CI 19.31-43.5 ng/mL). In the patients with breast cancer group, 45.28% (95% CI 24.37%-53.51%) had levels of 25-OHD below 20 ng/mL, whereas this percentage was 33.71% (95% CI 21.61%-45.82%) in controls. Similarly, 67.44% (95% CI 48.32%-86.55%) of patients with breast cancer had a baseline level of 25-OHD below 30 ng/mL, whereas this percentage was 33.71% (95% CI 21.61%-45.82%) in controls. CONCLUSION A high prevalence of vitamin D insufficiency is observed in patients with newly diagnosed breast cancer and may be linked pathophysiologically with breast cancer development or progression. Therapeutic benefits may be provided by manipulation of the vitamin D pathway in breast cancer.

[PMID: 32355643 PMCID: PMC7186238 DOI: 10.5306/wjco.v11.i4.217] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2019] [Revised: 03/12/2020] [Accepted: 03/26/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND In the six Gulf Cooperation Council countries (GCCCs), Bahrain, Saudi Arabia, Kuwait, Oman, Qatar and the United Arab Emirates, breast cancer (BC) is the greatest cause of cancer incidence and mortality. Obesity and physical inactivity are established risk factors for BC globally and appear to be more of a problem in high income countries like the GCCCs.
AIM To determine whether obesity and physical inactivity are associated with BC incidence in the GCCCs using the United Kingdom as a comparator.
METHODS This systematic review was carried out according to PRISMA guidelines. A cancer registry and a statistical data search was done to identify the BC incidence over the past two decades and the prevalence of obesity and physical inactivity in the GCCCs. Additionally, a systematic search of the databases, MEDLINE, Web of Science, and PubMed between 1999 and 2019 was performed to determine whether obesity and physical inactivity are risk factors for BC in the GCCCs. All papers were critically appraised according to their research methods and were assessed for quality and risk of bias.
RESULTS BC was the top malignancy in each GCC country. Women tended to be diagnosed with BC at a younger age than women in the United Kingdom. The greatest 10-year increase in BC incidence was seen in Saudi Arabia (54.2%), approximately seven times the rate of increase seen in the United Kingdom (7.6%). The prevalence of obesity and physical inactivity was greater in all the GCCCs in comparison to the United Kingdom. A total of 155 full studies were reviewed of which 17 were included. Of those, eight looked at the prevalence of obesity and physical inactivity in the Gulf States and nine looked at these as risk factors for BC. Only one study found an association between BC and obesity (odds ratio = 2.29). No studies looked solely at the link between physical inactivity and BC.
CONCLUSION The prevalence of obesity and physical inactivity was high within the GCCCs, but the majority of the included studies found no positive correlation between obesity or physical inactivity and BC. A high proportion of women in this study were pre-menopausal which could contribute to the negative findings.
