In regard with increasing use of brachytherapy for treatment of cancer, especially prostate cancer, dosimetry of the organs surrounding prostate is necessary. The received dose by prostate is relatively high and the healthy organs surrounding prostate are potentially at a risk of high dose too. In this paper, the doses delivered to the prostate and organs of interest were calculated by MCNP4C c...

  Background: Prostate cancer is one of the leading causes of cancer deaths among men. New gene expressed in prostate (NGEP), is a prostate-specific gene expressed only in normal prostate and prostate cancer tissue. Because of its selective expression in prostate cancer cell surface, NGEP is a potential immunotherapeutic target. To target the NGEP in prostate cancer, it is essential to investig...

Purpose: Non-cancerous prostate lesions such as prostate calcification, prostate enlargement, and prostate inflammation cause too many problems for men’s health. This research proposes a novel approach, a combination of image processing techniques and deep learning methods for classification and segmentation of the prostate in CT-scan images by considering the experienced physicians’ reports. ...

Prostate cancer is the most common and second leading cause of death among men in the world. Nowadays, radiotherapy has been known as one of the most affecting methods for prostate cancer treatment. Nevertheless, radiotherapy is accompanied by the concern of developing secondary cancers by the scattered radiation to the neighbor  organs at risk. Several studies have shown that secondary cancers...

Background and aim: The distinction between benign and malignant prostate lesions is one of the important issues in pathology. Misdiagnosis in these cases can lead to unnecessary treatments. The purpose of this study was to evaluate the diagnostic value of P504S sputum penetration in diagnosis of prostate cancer. Material and Methods: In this experimental study, 33 benign samples and 33 prosta...

Mestastatic prostate cancer cells (MPCCs) frequently metastasize to bone, which is a “favorite soil” for colonization and proliferation of MPCCs. Prostate cancer bone mestastasis is tightly associated with tumor-induced bone lesions, most commonly caused from the etiological imbalance between osteoblastic bone formation and osteoclastic bone resorption, and from the anti-tumor immune response. ...
