Circulating tumor cells (CTCs) are associated with cancer progression, aggressiveness and metastasis. However, the frequency and predictive value of CTCs in patients remains unknown. If circulating cells are involved in tumor aggressiveness and metastasis, then cell levels should decline upon tumor removal in localized cancer patients, but remain high in(More)
BACKGROUND The use of prostate-specific antigen (PSA) thresholds (<0.2 ng/ml) below currently accepted biochemical recurrence (BCR) definitions for patients treated with radical prostatectomy may be useful in the identification of candidates for early salvage therapy with improved outcome; however, the practice risks overtreatment, as the risk of subsequent(More)
The aim of our report was to describe the feasibility of robotic retroperitoneal lymph node dissection in the contemporary era. We suggest the linear port location and 90° robotic docking as the main key to minimizing instrument clashing and improving the range of surgical accessibility.
High-grade prostatic intraepithelial neoplasia (HGPIN) has been established as a precursor to prostatic adenocarcinoma. HGPIN shares many morphological, genetic, and molecular signatures with prostate cancer. Its predictive value for the development of future adenocarcinoma during the prostate-specific antigen screening era has decreased, mostly owing to(More)
Adrenocortical carcinoma (ACC) is a rare and clinically aggressive cancer. Previous studies reported increased recurrence rates associated with laparoscopic adrenalectomy (LA). We evaluated a single-center experience of LA versus open adrenalectomy (OA) for the management of ACC. Between 1993 and 2011, 44 consecutive patients with primary ACC were treated(More)
OBJECTIVE To assess the outcomes of robotic partial nephrectomy in patients with pre-existing chronic kidney disease (CKD). MATERIALS AND METHODS Patients who underwent robotic partial nephrectomy for renal tumors between 2007 and 2011 were identified from our prospectively maintained institutional database. Perioperative as well as short-term oncological(More)
BACKGROUND Cholesterol-lowering drugs known as statins have been reported to have significant anti-inflammatory properties. Given that inflammation may contribute to prostate cancer progression and that statins may reduce the risk for advanced prostate cancer, we investigated whether statin use was associated with reduced intratumoral inflammation in(More)
OBJECTIVE To determine whether presurgical sunitinib reduces primary renal cell carcinoma (RCC) size and facilitates partial nephrectomy (PN). METHODS Data from potential candidates for PN treated with sunitinib with primary RCC in situ were reviewed retrospectively. Primary outcome was reduction in tumor bidirectional area. RESULTS Included were 72(More)
Inflammation may play a role in the development and progression of many cancers, including prostate cancer. We sought to test whether histological inflammation within prostate cancer was associated with more aggressive disease. The slides of prostatectomy specimens were reviewed by a board-certified pathologist on 287 men from a Veterans Affairs Medical(More)
BACKGROUND Resveratrol increases lifespan and decreases the risk of many cancers. We hypothesized resveratrol will slow the growth of human prostate cancer xenografts. METHODS SCID mice were fed Western diet (40% fat, 44% carbohydrate, 16% protein by kcal). One week later, human prostate cancer cells, either LAPC-4 (151 mice) or LNCaP (94 mice) were(More)
