BACKGROUND AND PURPOSE The roles and criteria for pelvic lymph node dissection (PLND) are not fully evaluated in patients with low-risk prostate cancer who are treated by laparoscopic radical prostatectomy (LRP). In this study, the outcome of PLND was assessed in terms of the biochemical relapse-free survival rates of low-risk prostate cancer patients who(More)
A 53-year-old man presented for further evaluation due to microscopic hematuria and left lumbar pain. Computed tomography revealed a large tumour in the left renal pelvis with multiple metastases. Despite effective systemic chemotherapy, he developed dyspnea, and was diagnosed with cardiac tamponade. Pericardial involvement in an advanced malignancy is(More)
PURPOSE To determine predictive factors for perioperative complications of laparoscopic adrenalectomy (LA) including single-site surgery performed or supervised by experienced laparoscopic surgeons. PATIENTS AND METHODS We retrospectively reviewed 265 consecutive unilateral LAs performed at a single institution from 2001 to 2011. All surgical procedures(More)
OBJECTIVES To report our initial experience with transumbilical laparo-endoscopic single-site adrenalectomy for adrenal tumors by using a single port with a multichannel cannula and bent laparoscopic instrumentation. METHODS Between December 2009 and December 2010, 30 patients underwent transumbilical laparo-endoscopic single-site adrenalectomy at our(More)
LESS (laparoendoscopic single-site) surgery has been developed as a treatment option for adrenal tumors that has less postoperative pain and greater cosmetic benefits. Some reports proposed that patient selection criteria should be stringent, and pheochromocytoma (PHE) should be taken as an advanced indication. The aim of this study is to compare LESS(More)
Conventional laparoscopic adrenalectomy (LA) is the gold standard procedure for benign adrenal tumors. Laparoendoscopic single-site adrenalectomy (LESS-A) has been developed as an extension of standard laparoscopic minimally invasive procedures. This retrospective study compared the first experience of one surgeon with 70 LESS-A to 140 LA cases with respect(More)
OBJECTIVE Paraganglioma (PGL) is a rare type of tumor that arises from the extra-adrenal paraganglia. A PGL tumor hypersecretes catecholamines and causes symptoms identical to those in patients with hyper-functioning adrenal pheochromocytoma (PCC). In this study, we compared the surgical outcome of laparoscopic surgery, including laparoendoscopic(More)
OBJECTIVE To evaluate the suitability of preoperative multiparametric magnetic resonance imaging (MRI) positivity as a predictor of biochemical recurrence after radical prostatectomy (RP). PATIENTS AND METHODS We reviewed the clinical records of patients who underwent either standard RP or laparoscopic RP between January 2005 and December 2009 at our(More)
Thymidylate synthase (TS), a target enzyme of 5-fluorouracil (5-FU), is significantly associated with prognosis in various cancers. Recently, it has been reported that S-1, a novel 5-FU-based agent has an effect on bladder cancer. However, in cells with high TS level, S-1 did not have significant effects. Therefore, we examined whether down-regulation of TS(More)
Axl, which is in the TAM family of receptor tyrosine kinases, and its ligand, growth arrest-specific gene 6 (Gas6), have been associated with worse prognoses after the surgical treatment of some types of cancers. We herein investigated the biological significance of the protein expression of Axl and Gas6 on the outcomes of patients with upper tract(More)
