background: considering the ease of administration of capecitabne instead of infusional 5fu for concurrent radiochemotherapy (rct) of rectal cancer, the use of capecitabine has increased significantly in our radiation oncology department in the past years. thus we decided to compare the safety and survival with these 2 drugs by a retrospective review. methods: files of all patients receiving r...
Background & objectives: Competing risk data is one of the multivarite survival data. Competing risk data can be modelled using copula function. In this study we propose a bayesian modelling approach of competing risk data using the copula function.Methods: We used the data from colorectal cancer registyrarty in Tehran. After constructing likelihood function using Clayton copula by choosing app...
BACKGROUND The implementation of preoperative chemoradiation combined with total mesorectal excision has reduced local recurrence rates in rectal cancer. However, the use of both types of treatment in upper rectal cancer is controversial. OBJECTIVE The purpose of this work was to assess oncological results after radical resection of upper rectal cancers compared with sigmoid, middle, and lowe...
INTRODUCTION Rectal cancer is a common cancer worldwide. Low rectal cancer exhibits a tendency for recurrence. Surgical resection is an important treatment for rectal cancer. Cylindrical abdominal-perineal resection is suitable for patients with low rectal cancer and has helped improve the prognosis of these patients. However, there are some difficulties during the operation. Especially the per...
The aims of this study were to simultaneously evaluate the expression of Y-box binding protein-1 (YB-1) in non-neoplastic rectal tissue and rectal cancer tissue, and to collect clinical follow-up data for individual patients. Additionally, we aimed to investigate the developmental functions and prognostic value of YB-1 in rectal cancer. We performed immunohistochemical studies to examine YB-1 e...
background: in order to improve the evaluation of possible rectal toxicity based on the rectal normal tissue complication probability (ntcp), we consider the fractional dependence of the ntcp on the wall thickness (tw) and rectal displacement (rm). materials and methods: the two-dimensional ntcp model (ntcp2d) was developed using radiotherapy plans of ten randomly selected patients with prostat...
BACKGROUND Rectal cancer patients have a higher incidence of pulmonary metastases than those with colon cancer. This study aimed to examine the effects of rectal cancer level on recurrence patterns in rectal cancer patients. METHODS Patients with T3/T4 rectal cancers who underwent surgery between 2002 and 2006 were recruited in this study. All the patients were followed up on until death. Rec...
BACKGROUND Associations between colon and rectal cancer and intakes of vegetables, other plant foods, and fiber have stimulated much debate. OBJECTIVE We examined the association between rectal cancer and plant food and fiber intakes. DESIGN Data from 952 incident cases of rectal cancer were compared with data from 1205 population-based controls living in Utah or enrolled in the Kaiser Perm...
Cancer of the colon and rectum are two distinct entities, which require different treatment strategies and separate treatment. MicroRNAs (miRNAs) act as critical regulators of genes involved in several biological processes. Aberrant alterations of miRNAs have been found in several types of cancer, including colon cancer and rectal cancer. Extensive catalogues of downregulated miRNAs have been i...
Pathologic T1-2N0 rectal cancer shows an excellent prognosis without preoperative or postoperative chemoradiation. However, oncologic outcome of ypT1-2N0 remains unclear and undetermined. Thus, the aim of this study was to compare the survival of ypT1-2 and pT1-2 rectal cancer patients after radical resection and identify risk factors of ypT1-2 rectal cancer in Surveillance, Epidemiology, and E...
