Abstract

Abstract Background Colorectal cancer (CRC) is the first most common cancer in males and the third most common cancer in females in Saudi Arabia. Dietary habits are strongly associated with the inhibition or proliferation of malignancy. Therefore, this study is aiming to investigate the risks and protective benefits of dietary factors affecting CRC in the Mecca region of Saudi Arabia. Methods A case-control study was conducted from June 2014 to March 2015. One hundred thirty-seven patients with colon and/or rectal cancer were recruited in the case group, while 164 healthy participants were recruited in the control group. A questionnaire was completed with the help of trained dietitians to study the effects of several dietary patterns on the risk of CRC. Results Dairy product intake of 1–5 servings/day, legume intake of 3–5 servings/week, leafy vegetables intake of 1–5 servings/week, olive oil intake of 1–5 servings/week, black tea intake of three or more cups/day, and coffee intake of one or more cups/day was found to decrease the risk of CRC in participants. Conclusion This study highlights the importance of changing dietary habits to decrease CRC incidence in the Mecca region.

Abstract

Background: Colorectal cancer (CRC) is a significant healthcare burden worldwide and in the Middle East (ME). KRAS mutation confers resistance to epidermal growth factor receptor (EGFR) inhibitors in the treatment of advanced CRC. Data regarding the rate of KRAS mutation from the ME are scattered and scarce. We aim to collect and review all sizable studies evaluating the frequency of KRAS mutations in CRC patients from the ME. Method: A Pubmed and Google Scholar search was conducted using keywords including KRAS, K-ras, colorectal cancer and Middle East, along with names of each ME country. Studies including over 90 patients were included in the review. Result: Eleven studies containing more than 90 patients were identified. Among all eleven studies, KRAS mutation rate ranged from 13 to 56%. Five studies reported KRAS mutation rate in M1 stage either exclusively or as part of subgroup analysis. In these studies, mutations were found in 8-45% of cases. KRAS mutations were associated with female gender, M1 stage and high CEA in 3, 2, and 1 studies respectively. Conclusion: There is a broad range of variability in KRAS mutation rate reported in different studies from the ME. This may have been due to small number of patients in the studies and lack of centralized testing for KRAS mutations. Larger and more coordinated studies from the ME population are required to ascertain the accuracy of KRAS mutation rate.

Abstract

Background The prognosis of young colorectal cancer (CRC) patients has been addressed by several studies but with contradictory results. The aim of the present study was to evaluate the clinico-pathological features of young Saudi patients with CRC in addition to displaying their survival outcome. Materials and methods In this retrospective study, young CRC patients (≤ 40 years) diagnosed between 2007 and 2011 from 4 centres in western Saudi Arabia, were included. Clinico-pathological features, tumor markers, dates of disease relapse and death were collected. Survival parameters were compared with those of older Saudi patients, reported in previous studies. Results One hundred and sixteen young patients with CRC were identified (32.2% rectal, 67.8% colon). Some 44% were metastatic while 32.7% had stage III at diagnosis. Patients with grade 3 tumors made up 29.4% of the total while 49.5% had positive lymphovascular invasion (LVI), 56% had a lymph node (LN) ratio ≥ 0.2 and 40.2% were K-ras mutant. Median disease-free survival (DFS) and overall survival (OS) in non-metastatic cases were 22.8 and 49.6 months respectively with better median DFS in K-ras wild compared to mutant patients (28.5 vs 20.9 months, p=0.005). In metastatic cases, median OS was 19.5 months. These survival outcomes are inferior compared to those of older Saudi patients reported in prior studies. Conclusions Young CRC patients present more commonly with advanced stage and a high incidence of adverse prognostic factors such as LVI and high LN ratio. Young CRC patients seem to have worse survival compared to older Saudi patients.
