In recent years, significant development in the treatment of prostate cancer has taken place. One of the most documented methods of treatment in patients characterised by a high risk of progression is a combination of radiotherapy (RT) with long-term hormone therapy (HT). In this group of patients, neither RT alone nor HT alone allows satisfactory outcomes to be achieved, and therefore as monot...
Prostate cancer radiotherapy: potential applications of metal nanoparticles for imaging and therapy.
Prostate cancer (CaP) is the most commonly diagnosed cancer in males. There have been dramatic technical advances in radiotherapy delivery, enabling higher doses of radiotherapy to primary cancer, involved lymph nodes and oligometastases with acceptable normal tissue toxicity. Despite this, many patients relapse following primary radical therapy, and novel treatment approaches are required. Met...
BACKGROUND Diffuse renal and retroperitoneal metastasis of prostatic origin is an uncommon spread pattern of prostate cancer. CASE PRESENTATION We described a 74-year-old male patient who was admitted because of dysuria and nocturia. Physical examination and imaging study indicated prostate mass, and laboratory analysis revealed elevated prostate specific antigen (PSA). The diagnosis of prost...
Abstract Aim In this retrospective study, we evaluate patient outcomes for patients with localised Gleason 8-10 prostate cancer opting radical prostatectomy. Method A list of men on pre-operative biopsy who underwent prostatectomy (RP) within our tertiary referral unit between 1st January 2002 and 2nd June 2020 were obtained through departmental operative histology records. Electronic record sy...
INTRODUCTION Prostate cancer is now the third most frequent noncutaneous malignancy in Iranian men and the fifth most common cancer worldwide. Measurement of total serum prostate specific antigens (PSAs) has been one of the strongest predictors of biochemical progression and overall survival in determining the efficacy of definitive external beam radiation therapy in patients with localized pro...
Context: In absence of prospective randomized trials determining the optimal management of localized prostate cancer remains undefined. Objective: To develop and disseminate an update on outcome of different treatment modalities, recommendations and guidelines of transperineal prostate brachytherapy. Evidence acquisition: In the past decade, the average number of brachytherapy patients per cent...
PURPOSE Extraprostatic disease will be manifest in a third of men after radical prostatectomy. We present the long-term followup of a randomized clinical trial of radiotherapy to reduce the risk of subsequent metastatic disease and death. MATERIALS AND METHODS A total of 431 men with pT3N0M0 prostate cancer were randomized to 60 to 64 Gy adjuvant radiotherapy or observation. The primary study...
Metastases to pituitary gland are unusual and mostly asymptomatic, presenting with local symptoms in one of ten patients, and only 3%-5% of them are of prostate origin. Here we report and evaluate the effectiveness and safety of multimodal treatment in a patient with pituitary metastasis of a prostate foamy gland carcinoma. A 78-year-old male patient presented with blurred vision and headache w...
OBJECTIVE Cone beam CT (CBCT) enables soft-tissue registration to planning CT for position verification in radiotherapy. The aim of this study was to determine the interobserver error (IOE) in prostate position verification using a standard CBCT protocol, and the effect of reducing CBCT scan length or increasing exposure, compared with standard imaging protocol. METHODS CBCT images were acqui...
PURPOSE Elevated serum prostate specific antigen (PSA) may be the initial and only indication of disease recurrence after prostatectomy for prostate cancer. External beam radiotherapy may be given in this setting in an attempt to eradicate the disease but therapeutic outcomes after this approach require further description. We describe the intermediate term outcome in a large group of patients ...
