Clinical Aspects of Microsatellite Instability Testing in Colorectal Cancer---85

Background: Microsatellite instability (MSI) is a molecular hallmark for some colorectal cancers (CRCs) in which short tandem repeats are prone to mutations along with DNA sequences. It is due to DNA‑mismatch‑repair system deficiency because of a germline/somatic mutation in mismatch‑repair (MMR) genes. The germline mutations lead to Lynch syndrome (LS) while epigenetic gene silencing results in sporadic CRC tumors.

Familial Colorectal Cancer Type X in Central Iran: A New Clinic pathologic Description---105

Background: Familial colorectal cancer type X (FCCX) is a subtype of mismatchrepair (MMR)-proficient colorectal cancerin whichthe patients are clinicallyat risk for Lynch syndrome (LS), a common hereditary cancer predisposing syndrome.In this study, we describeda new clinicopathological feature of the condition in central Iran.

Diagnostic value of alarm symptoms for upper GI malignancy in patients referred to GI clinic: A 7 years cross sectional study---106

Background: Early upper gastrointestinal (UGI) cancer detection had led to organ‑preserving endoscopic therapy. Endoscopy is a suitable method of early diagnosis of UGI malignancies. In Iran, exclusion of malignancy is the most important indication for endoscopy.

Simplified microsatellite instability detection protocol provides equivalent sensitivity to robust detection strategies in Lynch syndrome patients---107

Background: Germline mutations in mismatch repair (MMR) genes cause Lynch syndrome (LS). LS is an inherited disease, and an important consequence of MMR deficiency is microsatellite instability (MSI) phenotype. MSI phenotype influences the efficacy of 5 fluorouracil (5-FU) chemotherapy.

Evaluation of MT1XT20 Single Quasi-Monomorphic Mononucleotide Marker for Characterizing Microsatellite Instability in Persian Lynch Syndrome Patients---277

Background: Colorectal malignancies with high microsatellite instability (MSI-H), either hereditary (Lynch syndrome) or sporadic, demonstrate better prognosis and altered response to 5FU chemotherapy. It is now recommended to perform MSI testing for all new cases of colorectal cancer regardless of being categorized as hereditary or sporadic. For MSI detection, immunohistochemistry or PCR-based protocols using a cohort of various sets of STR markers are recommended. Here we aimed to evaluate a simplified protocol using just a single STR marker, MT1XT20 mononucleotide repeat, for detection of MSI in Lynch syndrome patients. A Promega five-marker MSI testing panel and immunohistochemistry (IHC) were used as the gold standard in conjunction with MT1XT20.

Effects of Physical Activity on Risk of Colorectal Cancer: A Case–control Study---108

Background: The prevalence of colorectal cancer (CRC) is rapidly increasing in Iran. It holds the most prevalent cancer after skin, breast, and gastric cancers among the Iranian population. The current study was designed to investigate the effects of leisure time, occupational and household physical activity as well as exercise on the risk of CRC in the Iranian population.

Tumor microsatellite instability and clinicopathologic features in Iranian colorectal cancer patients at risk for Lynch syndrome---119

 Background:  Microsatellite instability (MSI) is a mutational signature that is the hallmark of Lynch syndrome, and MSI testing is a cost-effective method to screen the disease. Since there is no enough data about MSI status and associated clinicopathologic features of hereditary nonpolyposis colorectal cancer (HNPCC) in Iran, our study is a new trial to describe them in center of Iran (Isfahan).

Vitamin D Deficiency Is Associated With the Severity of Radiation-Induced Proctitis in Cancer Patients---122

Background: Radiation-induced injury to normal tissues is a common complication of radiation therapy in cancer patients. Considering the role of vitamin D in mucosal barrier hemostasis and inflammatory responses, we investigated whether vitamin D deficiency is associated with the severity of radiation-induced acute proctitis in cancer patients.

Molecular Analysis of Iranian Colorectal Cancer Patients at Risk for Lynch Syndrome: a New Molecular,Clinicopathological Feature---124

Background: Microsatellite instability (MSI) and mismatch repair (MMR) gene expression present a hallmark mutational signature of Lynch syndrome as a common hereditary cancer predisposing condition. Since there is not enough data of molecular and clinicopathological aspects of the disease in Iranian populations, this article is a new description in Central Iran.

MT1XT20 Single Quasi-Monomorphic Mononucleotide Marker for Detection of Microsatellite Instability in Iranian Patients with Hereditary Nonpolyposis Colorectal Cancer (HNPCC). ---125

Background: Colorectal malignancies with high microsatellite instability (MSI-H), either hereditary or sporadic, demonstrate better prognosis, altered response to fluorouracil (5FU) chemotherapy and altered operative approach. It is now recommended to perform MSI testing for all new cases of colorectal cancers regardless of being categorized as hereditary or sporadic. This study aimed to evaluate MT1XT20 mononucleotide marker in Iranian patients with hereditary nonpolyposis colorectal cancer (HNPCC). The samples were further characterized using Promega five-marker MSI testing panel and immunohistochemical (IHC) technique.

The status of lead and cadmium in soils of high prevalenct gastrointestinal cancer region of Isfahan---127

Background: Cadmium and lead compounds are classified as human carcinogens by several regulatory agencies. Twenty five percent of all cancer‑related deaths are attributed to gastrointestinal cancers (GI Ca). We investigated the levels of 2 different heavy metals (Cd and Pb) in the soils of the Lenjanat region, Isfahan province, Central Iran where intensive agriculture is surrounded by different industries like steel and cement‑making factories and mining and gastrointestinal cancers are very common in this province.

New interpretation for diagnostic yield of ileoscopy: a prospective study and a brief review---133

Background: Lower digestive endoscopy is mostly limited to the cecum without any attempt to penetrate the ileum. One of the probable reasons is the expectation of a low diagnostic yield. This study aimed to examine the feasibility of ileoscopy during colonoscopy and its diagnostic yield
