BACKGROUND Metabolic syndrome plays a potential role in the etiology of prostate cancer and is associated with the increase in prostatic growth rate in patients with benign prostatic hyperplasia. However, the influence of metabolic syndrome on prostate-specific antigen (PSA) level remains unclear. METHODS Data were obtained from 23,601 men ages 40 years(More)
PURPOSE To prospectively evaluate the diagnostic performance of double-echo gradient-echo (GRE) chemical shift magnetic resonance (MR) imaging in the differentiation of angiomyolipoma (AML) with minimal fat from other renal neoplasms, with pathologic examination or follow-up data serving as the reference standard. MATERIALS AND METHODS Institutional(More)
OBJECTIVE The effects of sunitinib in a broad patient population, especially those of Asian ethnicity, have been rarely investigated. Here, we assessed the efficacy and safety of sunitinib in Korean patients with advanced renal cell carcinoma. METHODS Between April 2006 and August 2008, 77 Korean patients with advanced renal cell carcinoma were treated(More)
Postprostatectomy erectile dysfunction (ED) is the major problem for patients with clinically localized prostate cancer. Recently, gene and stem cell-based therapy of the corpus cavernosum has been attempted for postprostatectomy ED, but those therapies are limited by rapid blood flow and disruption of the normal architecture of the corpus cavernosum. In(More)
The abilities of intracavernous injection of autologous stromal vascular fraction (SVF) and adipose-derived stem cells (ADSCs) to facilitate recovery of erectile function in a rat model of cavernous nerve (CN) injury were compared. Forty male Sprague-Dawley rats were randomly divided into four groups: sham and control groups (intracavernous injection of(More)
BACKGROUND This study investigated the efficacy and toxicity of sorafenib and sunitinib as primary treatment for patients with metastatic renal cell carcinoma (mRCC). METHODS We identified 49 and 220 patients treated with sorafenib and sunitinib, respectively, as first-line therapy in the Asan Medical Centre from April 2005 to March 2011. RESULTS(More)
The Toll-like receptor 4 (TLR4) has a wide spectrum of bacteria recognition receptors that may be involved in the signaling of the immune responses in the prostate. A few association studies have assessed the relationship between the risk of prostate cancer (PC) and the polymorphism in the TLR4 gene in European-ancestry populations. To evaluate the(More)
OBJECTIVES We examined whether altered protein expression for 7 potential biomarkers, including p53, pRb, PTEN, Ki-67, p27, FGFR3, and CD9, could predict tumor recurrence and progression in patients treated with bacillus Calmette-Guerin (BCG) therapy for primary stage T1 grade 3 (T1G3) bladder cancer (BC). MATERIALS AND METHODS The study included 61(More)
UNLABELLED Study Type - Therapy (case series) Level of Evidence 4 What's known on the subject? and What does the study add? To date, studies to evaluate clinical significance of prostate cancer detected on repeat biopsy in patients who underwent radical prostatectomy have yielded inconsistent results. The present study confirms that prostate cancer(More)
BACKGROUND We compared periprostatic implantation (PPI) and intracavernosal injection (ICI) of human adipose tissue-derived stem cell (ADSC) to facilitate recovery of erectile function in a rat model of cavernous nerve (CN) injury. METHODS Bilateral CN dissection (BCND) was induced in Sprague-Dawley rats. After BCND 10 rats each were treated with PPI(More)
