Background: Studies have shown the existence of gender- and age-related differences in the incidence and anatomic distribution of colorectal cancers. The purposes of this study were to analyze the distribution characteristics of colorectal cancer patients regarding gender, age, location and tumor size in the course of colonoscopy. Materials and Methods: All colorectal cancer patients who underwent colonoscopy in the First Affiliated Hospital of Guangxi Medical University from 2003 to 2012 were included in our retrospective study. Demographic information (age and gender) and colonoscopy report information (tumor size and location) were collected and analyzed. To compare the gender differences in tumor location and tumor size, as well as the size differences in tumor location, the chi-square test was used. Results: A total of 3, 369 colorectal cancer patients (2, 007 men vs 1, 362 women) were included in our study. Statistical analysis showed there was no gender difference in the anatomic distribution of the tumors (p>0.05). However, there was a gender difference in tumor size (p<0.05). In addition, our study found there was a significant difference in tumor size between rectal and colon tumors (p<0.001). Conclusions: There was no gender difference in the anatomic distribution of colorectal tumors. In addition, tumors observed in men were larger than in women.

Introduction: Design and implementation of screening programs in each country must be based on epidemiological data. Despite the relatively high incidence of CRC, there is no nationwide comprehensive program for screening in Iran. This study was designed to investigate national CRC data and help to determine guidelines for screening. Methods: Incidence data used in this study were obtained from Iranian annual of National Cancer Registration report. Age standardized rates (ASR)were calculated using world standard population and were categorized by age, sex, anatomic subsite and morphology of tumor. Data were analyzed using SPSS.V.13 and Open Source Epidemiologic Statistics for Public Health software (OpenEpi v.2.3.1). Results: A quarter of cases were less than 50 years of age. The majority of tumors were detected in the colon. The overall ASR in the four years period was 38.0 per 100000 and was higher for men compared women (P<0.05). Incidence rate of colorectal cancer increased with age. Conclusion: Results of present study indicated that incidence of colorectal cancer is relatively high in Iran. Incidence of CRC in people under 50 years and in rectum were reported higher than other countries that related etiologic factors should be investigate in further studies. According to the increasing of ASR after age 50 years, it seems that onset of screening at age 50 would be appropriate.

Surgical outcomes of colorectal cancer treatment depend not only on good surgery and tumor biology but also on an optimal perioperative care. The enhanced recovery program (ERP) - a multidisciplinary and multimodal approach, or so called 'fast-track surgery' - has been designed to minimize perioperative and intraoperative stress responses, and to support the recovery of organ function aiming to help patients getting better sooner after surgery. Compared with conventional postoperative care, the enhanced recovery program results in quicker patient recovery, shorter length of hospital stay, faster recovery of gastrointestinal function, and a lower incidence of postoperative complications. Although not firmly established as yet, the enhanced recovery program after surgery could be of oncological benefit in colorectal cancer patients because it can enhance recovery, maintain integrity of the postoperative immune system, increase feasibility of postoperative chemotherapy, and shorten the time interval from surgery to chemotherapy. This commentary summarizes short-term outcomes and potential long-term benefits of enhanced recovery programs in the treatment of colorectal cancer.

Background: Lymphoma is one of the most common malignancies affecting the young Saudi population. This disease has diversified pathologies and clinical stages that necessitate well optimized clinical management. Regular updates of epidemiological behavior of lymphoma from various parts of the world are available but studies from the Kingdom of Saudi Arabia (KSA) in this field are not consistent. Objectives: The aim of this study was to investigate the current trends in presentation and distribution of lymphoma with special reference to incidence and mortality, gender, age, histopathological subtypes, and clinical stages at King Faisal Specialist Hospital and Research Centre (KFSH&RC). Materials and Methods: Our study included lymphoma data from Saudi Cancer Registry, and relative comparison against KFSH&RC tumor registry data, Gulf country data and International Agency for Research on Cancer data. Results: Common tumors in the West (lung, colon, and prostate) were found to be much less frequent in KSA while leukemia, lymphoma and thyroid cancers were more common. Non-Hodgkin Lymphoma (NHL) ranked 3rd most common cancer with age-adjusted incidence of 6/100,000. Estimated age adjusted mortality was 4/100,000 in KSA. There was a peak rise in incidence of lymphoma in 1997-2007. Most common NHL was diffuse large B cell lymphoma at KFSH&RC. A total of 434 cases were diagnosed in 5 years with 55% of them at advanced stage and 35% demonstrating bulky disease and high risk. KFSH&RC registered 35% of Hodgkins and 21% of total NHL identified in entire Saudi Cancer Registry, 2009. Conclusions: Results of this study are very unique, and reveal diverse trends. The findings provide valuable insights in the understanding of current epidemiological features of lymphoma in this part of the world.

본 연구에서는 azoxymethane (AOM)과 dextran sodium sulfate (DSS)로 유도된 대장 발암과정에 대한 셀레늄의 방어 효과를 조사하였다. 셀레늄 결핍(0.02 ppm Se), 정상(0.1 ppm Se), 과다(0.5 ppm Se)사료를 12주간 식이로 급여하여 혈액검사와 대장암 발생의 초기단계인 aberrant crypt foci (ACF)수를 측정했으며, 암 발생율을 조사하였다. ICP-AES를 사용하여 간의 셀레늄 농도를 측정하였으며, 또한 셀레늄포함 항산화효소인 glutathione peroxidase (GPx) 활성을 알아보았다. 또한 TUNEL assay와 PCNA, $\beta$-catenin에 대한 면역조직 염색을 수행하였다. ACF 수 및 종양 발생률에 있어서, 셀레늄과다사료를 급여한 군이 정상셀레늄사료를 급여한 군보다 낮았으며, 셀레늄결핍사료를 급여한 군은 오히려 ACF 수 및 종양 발생률이 높았다. GPx 활성은 셀레늄의 섭취가 과다한 군에서 높게 나타났으며, 이 때, TUNEL에서 apoptotic positive cell이 증가하는 것을 확인했다. 또한 셀레늄의 섭취가 과다한 군에서 PCNA와 $\beta$-catenin의 발현이 감소됨을 볼 수 있었다. 본 마우스 모델실험에서 셀레늄은 여러 기전에 의해 대장암 발생을 억제할 수 있을 것으로 사료된다.

Aberrant DNA methylation plays a critical role in the development and progression of colorectal cancer (CRC), which has high incidence and mortality rates in Korea. Various CRC-associated methylation markers for cancer diagnosis and prognosis have been developed; however, they have not been validated for Korean patients owing to the lack of comprehensive clinical and methylome data. Here, we obtained reliable methylation profiles for 228 tumor, 103 adjacent normal, and two unmatched normal colon tissues from Korean patients with CRC using an Illumina Infinium EPIC array; the data were corrected for biological and experiment biases. A comparative methylome analysis confirmed the previous findings that hypermethylated positions in the tumor were highly enriched in CpG island and promoter, 5' untranslated, and first exon regions. However, hypomethylated positions were enriched in the open-sea regions considerably distant from CpG islands. After applying a CpG island methylator phenotype (CIMP) to the methylome data of tumor samples to stratify the CRC patients, we consolidated the previously established clinicopathological findings that the tumors with high CIMP signatures were significantly enriched in the right colon. The results showed a higher prevalence of microsatellite instability status and MLH1 methylation in tumors with high CMP signatures than in those with low or non-CIMP signatures. Therefore, our methylome analysis and dataset provide insights into applying CRC-associated methylation markers for Korean patients regarding cancer diagnosis and prognosis.
