In the stomach and large intestine we meet only too frequently with the same type of malignant disease, whereas in the small intestine carcinoma is very rare. The explanation may be that the stomach and large gut are constantly dealing with solid matter which moves on slowly and the small gut with fluids quickly passing on. The surface epithelium of the stomach at one end, and the rectum (the s...
Introduction: The close proximity of the rectum tissue to the prostate gland results in rectal toxicity during prostate radiotherapy. Rectal Retractor (RR) is a rectal displacement technique that inserts into the rectum, as a result, the lateral and dorsal part of the rectal wall push away from high dose areas. The aim of this study was to investigate the dosimetric consequence...
background: considering the importance of updating information about incidence and mortality of common or fatal cancers and the need for studying the effectiveness of changes in the iranian cancer registration system from pathological based to population based since 2007, the aim of this study was to provide updated population based information on incidence and mortality rates...
Background and Objectives: Cancer is the third cause of death in Iran. Gender is an important covariate for incidence of most cancers. So, epidemiological data on Gender differences related to common cancers provide good evidence in control of cancers. The aim of this study was providing population-based information on the gender differences in incidence rates and epidemiology of esophagus, s...
Background: Brachytherapy treatment planning in cervix carcinoma patients using two dimensional (2D) orthogonal images provides only point dose estimates while CT-based planning provides volumetric dose assessment helping in understanding the correlation between morbidity and the dose to organs at risk (OARs) and treatment volume. Objective: Aim of present study is to compare Internationa...
The relationship among the lysyl oxidase (LOX) G473A single nucleotide polymorphism (SNP), cigarette smoking and lung, colorectal, colon and rectum cancer susceptibility was studied in 200 cases of lung cancer, 335 cases of colorectal cancer including 130 cases of colon cancer and 205 cases of rectum cancer, and 335 healthy people in Tangshan, China. Peripheral blood DNA samples were collected,...
Cancer has been one of the haunted conditions in the society though there have been treatment methods developed to cure. External Beam Radiation Therapy (EBRT) is one such methods of cancer treatment. During the treatment plan phase, the organs at risk in the respective cancer context need to be segmented from acquired medical image. In this work, rectum is segmented from CT images and segmente...
Introduction: Colorectal carcinoma is primary epithelial malignancy arising in the colorectum areas. 98% of colonic and rectum cancers are adenocarcinomas. The prevalence colorectal cancer has been dramatically growing at an alarming rate globally recent years. Materials methods: This retrospective study Department Pathology B P Koirala Memorial Cancer Hospital effective from 1st January 2018 t...
Purpose:Colorectal cancer studies typically include both colon and rectum tumors as a common entity, though this assumption is controversial andonlyminor differences have been reported at themolecular and epidemiologic level. We conducted a molecular study based on gene expression data of tumors from colon and rectum to assess the degree of similarity between these cancer sites at transcriptomi...
