Background: The incidence of gastric cancer (GC) is high, and colorectal cancer (CRC) has significantly increased in Asian countries. Aim: To examine the current screening for GC and CRC within East Asia by means of a questionnaire survey. Methods: Representative members of the Committee of the International Gastrointestinal Consensus Symposium provided a questionnaire to physicians in six East Asian countries. Results: A total of 449 physicians participated in this survey. In all countries, more than 70% of physicians started GC screening between 40 and 59 years. The most popular method to screen for GC was endoscopy (92.7%), but combination methods such as Helicobacter pylori (HP) antibody, barium X-ray, and tumor marker with endoscopy differed by country. For HP-positive individuals, most physicians screened every year by endoscopy, and for individuals post-HP eradication, about half of physicians (56.3%) thought there was a need to follow-up with GC screening. Among all physicians, the most common age to start CRC screening was in the 40s (39.8%) and 50s (40.9%). Based on the American Cancer Society Recommendations, a fecal occult blood test every year was the most popular method for CRC screening overall. However, among each country, this test was most popular in only Japan (76.9%) and Indonesia. In other countries, sigmoidoscopy every 5 years and total colonoscopy every 10 years were the most popular methods. Conclusion: There are similarities and differences in the screening of GC and CRC among East Asian countries.

    • "Based on the American Cancer Society recommendations, a fecal occult blood test every year should be performed. However, among East-Asian country, this test was most popular in only Japan (76.9%) and Indonesia, sigmoidoscopy every 5 years and total colonoscopy every 10 years being the most popular methods[96]. In a multi-center study of adults 50 years and older, 27% had undergone previous colorectal cancer testing; the Philippines (69%), and Japan (38%) had the highest participation rates, whereas Malaysia (3%), Indonesia (3%), and Brunei (13.7%) had the lowest rates[97].

    ABSTRACT: Cancer is a major cause of mortality and morbidity throughout the world, including the countries of North-East and South-East Asia. Assessment of burden through cancer registration, determination of risk and protective factors, early detection and screening, clinical practice, interventions for example in vaccination, tobacco cessation efforts and palliative care all should be included in comprehensive cancer control programs. The degree to which this is possible naturally depends on the resources available at local, national and international levels. The present review concerns elements of cancer control programs established in China, Taiwan, Korea, and Japan in North-East Asia, Viet Nam, Thailand, Malaysia, and Indonesia as representative larger countries of South-East Asia for comparison, using the published literature as a guide. While major advances have been made, there are still areas which need more attention, especially in South-East Asia, and international cooperation is essential if standard guidelines are to be generated to allow effective cancer control efforts throughout the Far East.

    ABSTRACT: The aim of this study was to evaluate the necessity of preoperative colonoscopy (CS) in gastric cancer (GC) patients and to assess the outcomes of different treatments in patients with synchronous GC and colorectal neoplasms (CRN). We also determined the risk factors influencing the comorbidity of colorectal cancer (CRC) in patients with GC. This retrospective study included 1891 consecutive GC patients who underwent CS before surgery from January 1, 1999, through June 30, 2012. There was a high prevalence of concurrent CRN (28.4 %) and CRC (3.2 %) in our patients with GC. Sixty-one patients with GC had synchronous CRC. Twenty-three of the 61 tumors were perioperatively treated by endoscopic resection. The other 38 tumors were treated by simultaneous surgery for the GC and CRC. Surgical complications were not found in either the endoscopic or surgical resection group. The multivariate logistic regression analysis indicated that the prevalence of synchronous CRC in patients with GC was significantly associated with the incidence of multiple GCs [P < 0.0001; odds ratio (OR) 15.3], having anemia (P = 0.002; OR 3.0), and having a smoking history (P = 0.021; OR 1.9). We recommend preoperative CS screening for GC patients. In particular, preoperative CS screening is indispensable for patients with multiple GCs. In addition, simultaneous treatments for patients with synchronous GC and CRN are safe and feasible procedures.

    ABSTRACT: This study aimed to determine the correlation between HIF-1α and miR-27a expression and to evaluate the effect of inhibition of HIF-1α expression on miR-27a expression and drug resistance in gastric cancer (GC). In the present study, real time-PCR and Western blot were performed to detect the expression of HIF-1α in GC tissues and cell lines. Then, OCUM-2MD3/L-OHP cells were transfected with HIF-1α-siRNA, a miR-27a mimic or pcDNA-HIF-1α, and cell survival was determined via the MTT assay. The expression of HIF-1α, miR-27a, and MDR-related genes was measured via real time-PCR and Western blot. ChIP and dual luciferase activity assays were performed to assess the transcriptional regulation of HIF-1α and miR-27a. The results revealed that transfection with HIF-1α-siRNA markedly decreased the levels of miR-27a, resulting in dramatically enhanced inhibition of the proliferation rate of OCUM-2MD3/L-OHP cells. Compared to non-transfected cells, the survival rate was significantly reduced in the cells transfected with HIF-1α-siRNA after treatment with L-OHP. The cell survival rate was significantly increased in OCUM-2MD3/L-OHP cells transfected with the miR-27a mimic, whereas HIF-1α overexpression did not result in any clear change in cell survival. The results of the dual luciferase activity assay demonstrated that HIF-1α enhances the transcriptional activity of the miR27a promoter in cells transfected with a reporter plasmid containing the upstream promoter region of miR27a together with pcDNA-HIF-1α. ChIP analysis suggested that HIF-1α directly binds to the promoter region of miR27a. Inhibition of HIF-1α or miR27a expression decreased MDR1/P-gp, LRP, and Bcl-2 expression in OCUM-2MD3/L-OHP cells. Thus, we found that HIF-1α is closely associated with MDR in GC and that HIF-1α may suppress MDR1/P-gp, LRP and Bcl-2 expression by inhibiting miR-27a expression.
