we assessed the lower urinary tract symptoms (luts) in prostatic cancer patients and investigated the sensitivity and specificity of international prostate symptom score (ipss) in the screening of these patients. a total number of 132 prostatic cancer patients as the case group who were confirmed by the pathologists and 101 noncancerous men as the control group, aged 50 or older, responded to a...

PURPOSE Diffusion MRI is used frequently to assess prostate cancer. The prostate consists of cellular tissue surrounding fluid filled ducts. Here, the diffusion properties of the ductal fluid alone were studied. Monte Carlo simulations were used to investigate ductal residence times to determine whether ducts can be regarded as forming a separate compartment and whether ductal radius could dete...

Low dose rate brachytherapy is a widely used modality for the treatment of prostate cancer. Most clinical treatment planning systems currently in use approximate all tissue to water, neglecting the existence of inhomogeneities, such as calcifications. The presence of prostatic calcifications may perturb the dose due to the higher photoelectric effect cross section in comparison to water. This s...

This study aimed to calculate and compare the estimated organ absorption dose, risk of cancer due exposure, dose received by gonads for women men in radio diagnostic examinations with different projections. Radiographic examination abdomen (with anterior-posterior (AP) posterior-anterior (PA) projections) lumbar vertebrae projection (AP), Right oblique (RPO), Left (LPO)), were performed. Softwa...

The genetic factors underlying many complex traits are not well understood. The Genetic Analysis Workshop 15 Problem 1 data present the opportunity to explore whether gene expression data from microarrays can be utilized to define useful phenotypes for linkage analysis in complex diseases. We utilize expression profiles for multiple genes that have been associated with a disease to develop a co...

Patients who were previously treated for prostate cancer with radiation therapy are monitored at regular intervals using a laboratory test called Prostate Specific Antigen (PSA). If the value of the PSA test starts to rise, this is an indication that the prostate cancer is more likely to recur, and the patient may wish to initiate new treatments. Such patients could be helped in making medical ...

results like other cancers, prostate cancer is caused by an accumulation of genetic alterations in a cell that drives it to malignant growth. specific genes and gene alterations have been suggested to play a role in its development and progression. aneuploidy, loss of heterozygosity, gene mutations, hypermethylation and inactivation of specific tumour suppressor genes such as gstpi, apc, mdr1, ...

Background In radiotherapy, especially when treating children, minimising exposure of healthy tissue can prevent the development adverse outcomes, including second cancers. this study we propose a validated Monte Carlo framework to evaluate complete patient during paediatric brain cancer treatment. Materials and methods Organ doses were calculated for treatment diffuse midline glioma (50.4 Gy w...

this paper investigates the radiative absorptivity of a spherical cavity by using monte carlo techniques. several parameters such as the angle of incoming radiation which inters the cavity for both diffuse wall cavity and specular wall cavity has been  investigated. the absorptivity of a spherical cavity has been calculated and compared with the exact values when the angle of incoming radiation...

background & aim : prostate cancer is one of the most common cancers in males and the second leading cause of cancer-related deaths in palestine. although, many studies were conducted in de- veloped countries to evaluate quality of life (qol) in survivors of prostate cancer, the researchers could not find any study that was conducted in a developing country including palestine. therefore, the p...
