Cancer of the Rectum
نویسنده
چکیده
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 seat of election in the large bowel) at the other, must undergo more active reproduction and be more subject to irritation and mechanical injury than that of the small intestine.

The effects of volumetric changes on radiation doses of the rectum and bladder during radiotherapy in patients with prostate cancer
Background: In prostate radiotherapy, changes in the volume of the bladder and rectum can influence dose delivery. In this study, cone-beam computerised tomography (CBCT) imaging was used to assess volumetric, and corresponding radiation dosimetric changes, for the bladder and rectum in patients with prostate cancer treated using VMAT. Materials and Methods: Treatment planning computed tomograp...

Background and Aim: Increased mortality rate�due to prostate cancer shows the growth of this disease.Prostate cancer is the second most widespread malignancy after lung cancer in men.It is important to use new methods in the radiation therapy of prostate cancer that are associated with lower exposure of the normal tissues. Nowadays, in most of the radiotherapy centers in our country, the Co-60 ...
متن کاملThe effect of Rectal Retractor, a rectal protector on rectal dose in radical prostate radiotherapy
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...

Introduction: The aim of this retrospective study was to evaluate the variations in delivered dose to the bladder, rectum, and femoral heads of prostate cancer patients during a course of treatment by image-guided radiation therapy (IGRT). Materials and Methods: Overall, 15 patients with prostate cancer were selected and. Each week, for each patient five consecutive cone beam computed tomograph...
متن کاملProstate IMRT: Two-dimensional model of rectal NTCP employing the variability of rectal motion and rectum wall thickness
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...
متن کاملA Dosimetric Evaluation of Organs at Risk in Prostate Radiation Therapy using a MAGIC Gel Dosimeter
Introduction: Multiple fields and presence of heterogeneities create complex dose distributions that need three dimensional dosimetry. In this work, we investigated MR-based MAGIC gel dosimetry as a three-dimensional dosimetry technique to measure the delivered dose to bladder and rectum in prostate radiation therapy. Materials and Methods: A heterogeneous slab phantom including bones was made....
