The provincial health authority reported a high mortality rate from upper GI cancer in the newly established Ardabil Province of northwest Iran. A comprehensive search was undertaken to survey and register all cases of cancer during a 4-year (1996-1999) period among the indigenous population of Ardabil Province, including subjects seeking care in the cities(More)
BACKGROUND & AIMS Helicobacter pylori is the main cause of peptic ulceration and gastric adenocarcinoma. The vacuolating cytotoxin gene, vacA, is a major determinant of virulence. Two naturally polymorphic sites in vacA, the signal region and midregion, are well-characterized determinants of toxicity and markers of pathogenesis. The aim of this study was to(More)
For almost 30 years no population-based cancer statistics have been available with which to estimate the cancer burden in Iran. In 2002 and 2003 two separate reports of population based cancer registries were published from Iran and the cancer incidence rates from these sources have permitted informed estimates of cancer incidence and mortality to be(More)
The Helicobacter pylori duodenal ulcer promoting (dupA) gene has been previously described as a risk marker for duodenal ulcer (DU) development and a protective factor against gastric cancer (GC). Recent studies which have assessed the application of dupA in the prediction of clinical outcomes have been controversial. In the current study, the association(More)
Much is still to be learned about the assessment of simulation-based surgical skills training. However, assessing surgery skills through simulation is a new horizon in medical education. Providing a safe environment for surgical residents to assess their performance rigorously without placing patients in jeopardy is valuable. Using simulators (both warm and(More)
BACKGROUND Attempts for early detection of gastric cancer have recently focused on host's genetic susceptibility factors and gene-environment interactions. We have, herein, studied the association of MTHFR C677T single nucleotide polymorphism (SNP) and its interaction with Helicobacter pylori infection, smoking, age and gender on the risk of gastric cancer(More)
BACKGROUND Health related quality of life (HRQOL) is an important outcome after treatment for upper gastrointestinal carcinoma. This study aimed to compare HRQOL in patients with advanced gastric cancer (GC) receiving either a standard or an experimental treatment. METHODS Seventy-one patients have been treated in Cancer Institute (Tehran, Iran) with(More)
Breast cancer is one of the most frequent malignancies among Iranian women, however; the epidemiological aspects of breast cancer among Iranian patients are uncertain. A literature review of the published articles from January 1998 to December 2005 was conducted using different search engines: MEDLINE, Scientific information data base of Academic Center for(More)
BACKGROUND Breast cancer is the most common female malignancy and a major cause of death in middle-aged women. So far, germline mutations in the BRCA1 and BRCA2 genes in patients with early-onset breast and/or ovarian cancer have not been identified within the Iranian population. METHODS With the collaboration of two main centres for cancer in Iran, we(More)
Kaposi's sarcoma (KS) is the rarest cancer among Iranian. This study was conducted to define the epidemiology of KS in Iran. The data of National Cancer Registry (NCR) reports from 2003-2006, Tehran Population Based Cancer Registry (TCR) from 1998 to 2001, and a literature review of the published articles until Aug. 2007 was conducted, the search strategy(More)
