PURPOSE To evaluate the prognostic value of prostate-specific antigen nadir (nPSA) after high-dose-rate (HDR) brachytherapy in clinically non-metastatic high-risk prostate cancer patients. MATERIAL AND METHODS Data from 216 patients with high-risk or locally advanced prostate cancer who underwent HDR brachytherapy and external beam radiation therapy with long-term androgen deprivation therapy...
To cite: Arora A, Jaiswal R, Anand N, et al. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2016218384 DESCRIPTION A 58-year-old man presented with history of irritative lower urinary tract symptoms (daytime frequency and nocturia) for 3 months. Digital rectal examination revealed grade 2 prostatomegaly and consistency was hard. Serum prostate-specific antigen (P...
Gleason pattern 5 (GP5), including tertiary GP5, at radical prostatectomy has reportedly been associated with poorer clinical outcome. However, it is undetermined how tertiary GP5 is handled in the new Gleason grade grouping starting in 2016, and its prognostic value in patients undergoing salvage treatment for postoperative biochemical recurrence (BCR) remains unclear. We retrospectively revie...
BACKGROUND The prognostic factors for the recurrence of lymph node (LN) metastasis after dose-escalated radiotherapy (RT) in prostate cancer patients have not been well investigated. We report the prognostic factors and outcomes in patients receiving salvage treatment for LN recurrence after high-dose intensity-modulated RT (IMRT). METHODS We studied a cohort of 419 patients with localized pr...
امروزه, گازهای خالص در صنعت و پزشکی, کاربردهای فراوانی دارد و با توجه به کاربرد روز افزون این گازها, روش های متفاوتی برای خالص سازی آن ها وجود دارد که یکی از این روش ها ، روش جذب تناوبی فشار (pressure swing adsorption یا psa )است. در این پروژه, هدف شبیه سازی عددی فرآیند جداسازی اکسیژن از هوا در بستر فشرده، و همچنین بررسی تأثیر فشار ورودی بر میزان جذب است. شبیه سازی جذب در بستر فشرده, قدم اول در...
abstract background: regarding the variety of tests present for detecting and also screening prostate cancer and also bearing in mind the advantages and disadvantages of these tests we decided to re-evaluate these tests (total prostate specific antigen and all of its modifications) in detecting prostate cancer in men with intermediate serum psalevels. methods: following a cross sectional st...
QUESTIONS UNDER STUDY/PRINCIPLES A retrospective assessment of long-term results on a single centre, single author experience in treating prostate cancer with high dose curative radiotherapy (RT) with or without androgen deprivation (AD). METHODS Between 1991 and 2004, 408 patients with clinically localised prostate cancer were treated with RT (+/-AD) at the University Hospital of Geneva. RT ...
BACKGROUND The optimal timing of salvage androgen deprivation therapy (ADT) for biochemical recurrence after radical prostatectomy is controversial. We compared the outcomes of ultra-early versus early salvage ADT. METHODS Among 855 patients undergoing radical prostatectomy at our institution between 2000 and 2012, we identified 121 with adjuvant-treatment-naïve pT2-4N0M0 prostate cancer who ...
OBJECTIVE To evaluate the relationship between two year PSA nadir (PSAn) after brachytherapy and biochemical recurrence rates in prostate cancer patients. MATERIALS AND METHODS In the period from January 1998 to August 2007, 120 patients were treated with iodine-125 brachytherapy alone. The results analysis was based on the definition of biochemical recurrence according to the Phoenix Consens...
