There are presented results of surgical treatment of 347 patients with colorectal cancer. Based on the retrospective analysis a comparative study of results of surgical treatment for colorectal cancer using laparoscopic technologies and “open” access was carried out. Predictive factors that correlate with the risk of postoperative complications with laparoscopic and “open” access at the surgical stage of treatment for colorectal cancer were determined.

Abstract Background Colorectal cancer (CRC) is one of the leading causes of mortality and morbidity in the world. It is the third most common malignancy after lung & breast and the fourth leading cause of cancer-related deaths worldwide, accounting for approximately 1,400,000 new cases and about 700,000 deaths worldwide. Objectives The aim of this retrospective study is to compare the epidemiology, clinicopathologic features, different treatment modalities and outcomes regarding disease free survival (DFS), progression free survival (PFS) & overall survival (OS) of colorectal cancer disease between cases presented to Ain shams university hospital & to Luxor international hospital in 3 consecutive years. Patients and Methods The study is retrospective comparative study. Clinical oncology department in Ain Shams University Hospital and Luxor International Hospital. The data Collected from January 2013 to December 2015. This study analyzed hospital records of patients who diagnosed with colorectal cancer (CRC) and allocated into two groups: Group A: CRC patients presented to Ain-Shams University Hospital from January 2013 to December 2015, group B: CRC patients presented to Luxor International Hospital from January 2013 to December 2015. Results There was no statistically significant difference regarding age parameter in LIH when compared to ASU, but the study was consistent with higher incidence in patients who were aged more than forty- accounted about 70.5% in all CRC cases. Cases less than 40 years old, in group A were 35.2%, while in Group B were 23.5%. Even there was no statistically significant difference but it may be attributable to more westernization in Lower Egypt. Other explanation may be due to decreased low socioeconomic status and different lifestyle factors in more developing region what increase risk of colorectal cancer. Among our cases, there is no statistically significant difference regarding gender between the two hospitals. Both sexes almost were affected equally, females appeared to be at a slightly higher risk of developing CRC cancer with current prevalence 1.3:1 in ASU group, and 1.1:1 in LIH group. Conclusion The need to increase awareness about CRC in Egypt especially upper Egypt, is recommended. An awareness campaign should be performed to promote detection of CRC at its earliest and most curable stage by recognizing early symptoms and enabling early referrals for colonoscopy. Those at higher risk should be offered more intensive surveillance. Similarity of the data from different centers suggests that this is the picture of colorectal cancer typical of Egypt.

Colorectal cancer (CRC) is a major cause of morbidity and mortality throughout the world and is the second most common cause of Canadian cancer-related deaths in men and the third most common in women. Most CRC appears to arise from the gradual development and advancement of colonic adenomatous polyps to cancerous tissue. This developmental process of CRC is the rationale for screening programs which aim to reduce CRC-related morbidity and mortality by early detection and removal of adenomatous polyps, specifically advanced adenomas. Although both the gFOBT and FIT function to detect occult bleeding in asymptomatic patients at average risk for CRC development, the mechanisms of these screening tests are distinct. gFOBT works by detecting the peroxidase activity of heme whereas FIT selectively detects human hemoglobin. The sensitivity in detecting CRC is higher for the FIT, with sensitivity of 0.79 compared to gFOBT with sensitivity of 0.36, they have similar specificities of 0.94 and 0.96, respectively. Currently, both the gFOBT and FIT are strongly recommended across Canada, with all provinces using the FIT, apart from Ontario and Manitoba which currently use the gFOBT to screen asymptomatic patients for CRC. A newer test, the sDNA test, identifies mutations in DNA that are shed by both adenomatous polyps and CRC cells. The sDNA test is more sensitive (0.92 95% CI 0.83-0.98) than both the gFOBT and FIT, however, is less specific and more expensive. Further data surrounding the sDNA test will be required prior to its implementation and recommendation for population based CRC screening in Canada.

Abstract Background: Tumor pyruvate kinase M2 isoform (tM2-PK), which is an isoform of PK-glycolytic enzyme and appears on the surface of cancerous proliferating cells, has been used as a diagnostic biomarker for colorectal cancer (CRC). The aim of this study was to evaluate the tM2-PK measurement test for the diagnosis of CRCs and adenomatous polyps in plasma and stool samples in an Iranian population. Methods: In this prospective study, a total of 226 stool and 178 plasma samples were received from patients referred to colonoscopy units. tM2-PK enzyme was measured using two separate ScheBo-Biotech-AG ELISA kits for stool and plasma samples. Results: At the cut-off value of 4 U/ml, in tumor group, the sensitivity of fecal tM2-PK test was 100% and the specificity was 68%, and in polyp group, the sensitivity and specificity were 87% and 68%, respectively. At the cut-off value of 15 U/ml in tumor group, the sensitivity of plasma tM2-PK test was 98% and specificity was 74% and in polyp group the sensitivity and specificity were 98% and 74%, respectively. Based on our results, a cut-off range of 4.8-8 U/ml and >8 U/ml could be used to detect polyp and tumor in stool samples, respectively. Similarly, a cut-off range of 19-25 U/ml and >25 U/ml is recommended in plasma samples for polyp and tumor detection, respectively. Conclusions: This study revealed a high specificity and sensitivity of tM2-PK test for stool and plasma samples in patients with CRC and polyps suggesting it as a non-invasive assay to diagnose CRC and adenomatous polyps.
