Background: Gastrointestinal (GI) malignancies are the most common cancers and account for nearly half of all cancer-related deaths in Iran. There was a strong association between human papillomavirus (HPV) infection and urogenital cancers, in particular the cervix. However, there is no clear causal relationship in all types of cancers, including gastrointestinal cancers. Therefore, the present...

introduction: numerous studies have investigated the prevalence, incidence and clinical manifestations of gastrointestinal stromal tumors (gists). however, little is known about gists in iran. this pioneer study focuses on description of 36 patients with gists in iran. methods: a database was created for 36 patients suffering from gist who were treated in loghman medical center and tehran cance...

Gastrointestinal oncology is one of the foremost causes of death: the gastric cancer accounts for 10.4% of cancer deaths worldwide, the pancreatic cancer for 6%, and finally, the colorectal cancer for 9% of all cancer-related deaths. For all these gastrointestinal cancers, surgical tumor resection remains the primary curative treatment, but the overall 5-year survival rate remains poor, ranging...

AIM To assess the association between excess body weight and cancer risk in patients with type 2 diabetes (T2D) who were registered in the Swedish National Diabetes Register (NDR). METHODS This is a cohort study based on 25,268 patients with T2D and baseline BMI≥18.5 kg/m(2) from NDR 1997-1999. Subjects were grouped according to BMI into normal weight (18.5 to 24.9), overweight (25 to 29.9) o...

BACKGROUND Lower gastrointestinal endoscopy can decrease colorectal cancer risk strongly through detection and removal of adenomas. Thus, we aimed to investigate whether utilization of lower gastrointestinal endoscopy modifies the effect of lifetime smoking exposure on colorectal cancer risk in a population-based case-control study. METHODS In this study from Southern Germany including 2,916 ...

The scored Patient-Generated Subjective Global Assessment (PG-SGA) is considered to be the most appropriate tool for detecting malnutrition in cancer patients. In particular, malignant tumours derived from the gastrointestinal tract may impair nutrient intake and absorption and cause malnutrition. We carried out a cross-sectional study to assess the nutritional status and related factors of pat...

Cancer immunotherapy is at dawn of the Renaissance after the Medieval Dark Ages. Recent advances of understanding tumor immunology and molecular drug development are leading us to the epoch of cancer immunotherapy. Some types of immunotherapy have shown to provide survival benefit for patients with solid tumors such as malignant melanoma, renal cell carcinoma, or non-small cell lung cancer. Sev...
