Transitional bladder carcinoma (BCa) is prevalent in developed countries, particularly among men. Given that these tumors frequently recur or progress, the early detection and subsequent monitoring of BCa at different stages is critical. Current BCa diagnostic biomarkers are not sufficiently sensitive for substituting or complementing invasive cystoscopy.(More)
PURPOSE The prognostic significance of perineural invasion by prostate cancer is debated. We investigated the association between perineural invasion and clinicopathological factors and the effect of perineural invasion on survival in patients with prostate cancer. MATERIALS AND METHODS A total of 361 patients with prostate cancer without any neoadjuvant(More)
A 71-year-old man was referred for painless hematuria and a bladder tumor. Cystoscopy and computed tomography revealed a 3-cm oval nodular mass on the left lateral side of the bladder. The patient underwent a complete transurethral resection of the lesion and histology showed a proliferation of atypical spindle cells with inflammation consistent with a(More)
Phosphatidylinositol 3-kinase (PI3K) is essential for both G protein-coupled receptor (GPCR)- and receptor tyrosine kinase (RTK)-mediated cancer cell migration. Here, we have shown that maximum migration is achieved by full activation of phosphatidylinositol 3,4,5-trisphosphate-dependent Rac exchanger 1 (P-Rex1) in the presence of Gβγ and PI3K signaling(More)
Although prostate-specific antigen (PSA) is a very useful screening tool, prostate biopsy is still necessary to confirm prostate cancer (PCA). However, it is reported that PSA is associated with a high false-positive rate and prostate biopsy also has various procedure-related complications. Therefore, the authors have devised a nomogram, which can be used(More)
PURPOSE We present our initial experience and surgical outcomes for the most recent refinement of bilateral intrafascial nerve-sparing extraperitoneal laparoscopic radical prostatectomy (nsELRP). MATERIALS AND METHODS Among 62 patients who underwent laparoscopic radical prostatectomy, 50 patients underwent intrafascial nsELRP by a single surgeon at Pusan(More)
A 26-year-old man complained of a vague low abdominal discomfort for the previous 2 months. Radiologic evaluations demonstrated that there was tubular structure connected with the right side wall of the bladder, suggesting Meckel's diverticulum with fistula formation to the bladder as well as a mass-like bladder wall thickening. With an impression of(More)
PURPOSE To evaluate the oncologic outcomes between adjuvant radiotherapy (ART) and salvage radiotherapy (SRT) in patients with locally advanced prostate cancer or with adverse pathologic factors including positive surgical margin and high Gleason score. MATERIALS AND METHODS We searched the literature published from January 2000 until December 2014 at(More)
PURPOSE To investigate the efficacy of androgen deprivation treatment (ADT) between continuous and intermittent ADT. MATERIALS AND METHODS Between January 2006 and May 2015, 603 patients were selected and divided into continuous ADT (CADT) (n=175) and intermittent ADT (IADT) (n=428) groups. The median follow-up in this study was 48.19 (1.0-114.0) months.(More)
Androgen receptor (AR) signaling is important for prostate cancer (PCa) cell proliferation. Here, we showed that proliferation of hormone-sensitive prostate cancer cells such as LNCaP was significantly enhanced by testosterone stimulation whereas hormone-insensitive prostate cancer cells such as PC3 and VCaP did not respond to testosterone stimulation.(More)
