BACKGROUND The recent development of multiple targeted agents for metastatic renal cell carcinoma (mRCC) has changed the treatment paradigm; hence the benefit and optimal timing of cytoreductive nephrectomy is being reevaluated. OBJECTIVE To determine primary tumor response to treatment with targeted agents in patients with mRCC. DESIGN, SETTING, AND(More)
BACKGROUND In metastatic renal cell carcinoma (mRCC) patients treated with targeted agents and their primary tumor (PT) in situ, early PT decrease in size correlates with improved overall PT response, but the effect on overall survival (OS) is unknown. OBJECTIVE To evaluate whether early PT size reduction is associated with improved OS in patients with(More)
BACKGROUND While perioperative blood transfusion (BT) has been associated with adverse outcomes in multiple malignancies, the importance of BT timing has not been established. OBJECTIVE The objective of this study was to evaluate whether intraoperative BT is associated with worse cancer outcomes in bladder cancer patients treated with radical cystectomy(More)
BACKGROUND Surgery for renal cell carcinoma (RCC) patients with inferior vena cava (IVC) thrombus above the hepatic veins is technically complex and associated with an increased risk of perioperative morbidity and mortality. However, minimal data exist that describe contemporary perioperative outcomes at major referral centers or the prognostic factors(More)
Metastatic renal cell carcinoma (RCC) has traditionally been associated with a poor prognosis with few effective treatments. In the multimodal treatment of metastatic RCC, cytoreductive nephrectomy (CN) became the standard of care after two randomized trials demonstrated a benefit in overall survival in patients who received CN prior to treatment with(More)
BACKGROUND Many patients with low-risk prostate cancer (PC) who are diagnosed with Gleason score 6 at biopsy are ultimately found to harbor higher grade PC (Gleason ≥ 7) at radical prostatectomy. This finding increases risk of recurrence and cancer-specific mortality. Validated clinical tools that are available preoperatively are needed to improve the(More)
OBJECTIVE To evaluate the ability of preoperative neutrophil-lymphocyte ratio (NLR) to predict pathologic upstaging and nonorgan-confined (NOC) (≥pT3) disease. METHODS AND MATERIALS After institutional review board approval, the records of consecutive patients undergoing radical cystectomy (RC) for urothelial carcinoma from 2002 to 2012 at the University(More)
The increased use of abdominal imaging has led to identification of more patients with incidental renal masses, and renal mass biopsy (RMB) has become a popular method to evaluate unknown renal masses prior to definitive treatment. Pathologic data obtained from biopsy may be used to guide decisions for treatment and may include the presence or absence of(More)
PURPOSE Percutaneous radiofrequency ablation and cryoablation are accepted alternative treatments for small renal cell carcinomas (RCC) in high-risk patients. The recent development of high-powered microwave (MW) ablation offers theoretical advantages over existing ablation systems, including higher tissue temperatures, more reproducible ablation zones, and(More)
PURPOSE As treatment options evolve for metastatic renal cell carcinoma, there is a need for predictive information to help guide therapy. We assessed the accuracy of percutaneous primary tumor biopsy for metastatic renal cell carcinoma by comparing biopsy findings to final nephrectomy pathology in patients undergoing cytoreductive nephrectomy.
