Background: According to the EAU guidelines, a life expectancy of more than 10 years is considered an important factor in the treatment of prostate cancer. The Charlson score is used to predict mortality based on comorbidies.The purpose of this study was to investigate the relationship between age, Charlson score and outcome in patients with cT3a prostate cancer. Materials and Methods: Between ...
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...
PURPOSE To evaluate the characteristics of patients who received primary androgen deprivation therapy (PADT) for prostate cancer and the clinical efficacy of this treatment. MATERIALS AND METHODS Two hundred forty patients treated by PADT were reviewed. These patients could not receive definitive therapy owing to old age, patient need, and medical comorbidity. The patients were divided into t...
Using the Monte Carlo N-Particle computer code (MCNP), doses were calculated for organs of interest such as the stomach, prostate, liver, and kidneys while patients were undergoing prostate brachytherapy. This research is important because the doses delivered to the prostate are extremely high and the organs near the prostate are potentially at risk of receiving high doses of radiation, ...
introduction dose calculation of tumor and surrounding tissues is essential during prostate brachytherapy. three radioisotopes, namely, 125i, 103pd, and 131cs, are extensively used in this method. in this study, we aimed to calculate the received doses by the prostate and critical organs using the aforementioned radioactive seeds and to investigate the effect of scattering contribution for the ...
Background: Some tissues in human body are radiobiologically different from water and these inhomogeneity must be considered in dose calculation in order to achieve an accurate dose delivery. Dose verification in complex radiation therapy techniques, such as intensity‐modulated radiation therapy (IMRT) calls for volumetric, tissue equivalent and energy independent dosimeter. The purpose of this...
conclusions psa, psa density, and gleason score should be considered together in order to more accurately predict the adverse pathologic features of prostate cancer. methods we conducted a cross-sectional study of 105 patients with localized prostate cancer who underwent radical prostatectomy between 2006 and 2013. we recorded gleason scores and psa levels, in addition to the results of patholo...
Background: Benign prostatic hyperplasia (BPH) is a common disease among older men and many patients with prostate cancer (PC) also have BPH. External beam radiation therapy (EBRT) is one of the important treatments for PC, nevertheless, few studies have analyzed the effect of BPH on EBRT. We tried to know the risk of bladder toxicity by analyzing the bladder volume variability in patients with...
background transurethral resection of the prostate (turp) is the most common surgical treatment for benign prostatic hyperplasia. objectives the aim of the present study was to compare the conventional bipolar transurethral resection of prostate (turp) with a modified transurethral resection of the prostate (m-turp) in men with mild to moderate symptoms of benign prostatic hyperplasia. patients...
Introduction: Radical prostatectomy is an effective curative treatment option for organ-confined prostate cancer. There is a recent trend in offering curative treatment to patients with oligometastatic disease. More sensitive imaging modalities can identify oligometastatic disease that is not usually detected by conventional imaging techniques. Case presentation: We present a case in which a s...
