Although cisplatin-based chemotherapy is the standard of care for advanced transitional cell carcinoma, tolerability is a challenging issue in unfit patients. This study was conducted to evaluate the efficacy, toxicity, and tolerability of the combination of gemcitabine and carboplatin in unfit patients with advanced transitional cell carcinoma. Thirty-one(More)
PURPOSE The study was to compare the oncologic and functional outcomes of partial nephrectomy (PN) and radical nephrectomy (RN) for pathologically proven T1b renal cell carcinoma using pair-matched groups. MATERIALS AND METHODS We reviewed our prospectively maintained database for RN and PN in T1b renal tumors surgically treated between 1999 and 2011 at(More)
OBJECTIVES To assess the characteristics of pseudocapsule (PC) in localized renal cell carcinoma (RCC) by analyzing the rates of completeness of PC and pseudocapsular invasion and clinical and pathological risk factors of it. MATERIALS AND METHODS Between February 2013 and September 2015, data were gathered prospectively from 180 consecutive patients who(More)
PURPOSE We analyzed a series of patients who had undergone laparoscopic partial nephrectomies (LPNs) and open partial nephrectomies (OPNs) to compare outcomes of the two procedures in patients with pathologic T1a renal cell carcinomas (RCCs). MATERIALS AND METHODS From January 1998 to May 2009, 417 LPNs and 345 OPNs were performed on patients with small(More)
PURPOSE The aim of this study was to determine the effect of preoperative chronic kidney disease (CKD) on the prognosis of patients with upper urinary tract urothelial carcinoma (UTUC) who had undergone radical nephroureterectomy (RNU). RESULTS The median follow-up period was 31.1 months (interquartile range: 16.2-55.7 months). Among the study patients,(More)
BACKGROUND The survival benefits of adrenalectomy (ADx) in the setting of metastatic cancer and prognostic factors for recurrence-free (RFS) and overall survival (OS) after adrenalectomy for metastatic carcinoma are still under debate. We evaluated the impact of clinicopathological variables on RFS and OS after ADx for metastatic carcinoma in patients with(More)
Recently, several studies have shown that the De Ritis ratio (aspartate transaminase/alanine transaminase) can be a useful prognostic biomarker for certain types of malignant tumors. However, the prognostic value of the De Ritis ratio in patients with upper tract urothelial carcinoma remains largely unknown. The aim of the present study was to evaluate the(More)
PURPOSE The incidence of single positive core prostate cancer at the time of biopsy appears to be increasing in the prostate-specific antigen (PSA) era. To determine the clinical implication of this disease, we analyzed surgical and pathological characteristics in comparison with multiple positive core disease. MATERIALS AND METHODS Among 108 consecutive(More)
OBJECTIVE To investigate the practice patterns of urologists in managing Korean men aged 40 years or younger with high serum prostate-specific antigen (PSA). MATERIALS AND METHODS Data were collected from general health screenings conducted at 4 university hospitals between 2004 and 2012. Eligibility criteria were Korean men aged≤40 years who were seen by(More)
PURPOSE There is no established standard second-line chemotherapy for patients with advanced or metastatic urothelial carcinoma (UC) who failed gemcitabine and cisplatin (GC) chemotherapy. This study was conducted in order to investigate the efficacy and toxicity of modified methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) in patients with(More)
