The expression of immunoglobulin-based artificial receptors in normal T lymphocytes provides a means to target lymphocytes to cell surface antigens independently of major histocompatibility complex restriction. Such artificial receptors have been previously shown to confer antigen-specific tumoricidal properties in murine T cells. We constructed a novel(More)
The genetic transfer of antigen receptors provides a means to rapidly generate autologous tumor-reactive T lymphocytes. However, recognition of tumor antigens by cytotoxic T cells is only one step towards effective cancer immunotherapy. Other crucial biological prerequisites must be fulfilled to expand tumor-reactive T cells that retain a functional(More)
BACKGROUND The postcystectomy survival benefit associated with the combination of methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) neoadjuvant chemotherapy (NC) for muscle-invasive bladder cancer has been most evident in patients who achieve a pathologic complete response. The outcome of NC and open radical cystectomy (RC) was evaluated in a(More)
OBJECTIVES The current tumor-node-metastasis (TNM)-staging system for urothelial carcinoma of the bladder (UCB) is based on the number and size of the largest positive lymph node (LN). The aggregate LN metastasis diameter (ALNMD) may better reflect the burden of metastatic disease and improve the ability to predict recurrence-free (RFS) and overall survival(More)
OBJECTIVE To report changes in grade and stage between initial diagnostic and repeat biopsies or resection for urothelial carcinoma (UTUC) and investigate the consequences for endoscopic management. Ureteroscopic management of upper tract UTUC is an alternative to nephroureterectomy, which is less invasive and preserves renal function. However, concerns(More)
PURPOSE Extended lymph node dissection for bladder cancer provides better staging, cancerous node removal and potentially survival. Minimally invasive techniques have been criticized about the ability to adequately perform extended lymph node dissection. We compared the extended lymph node dissection quality of robotic and open cystectomy by assessing node(More)
Tomato and soy products are hypothesized to reduce the risk of prostate cancer or enhance efficacy of therapy. A study was completed to determine if men with active prostate cancer will adhere to a dietary intervention rich in tomato products and a soy protein supplement men (n = 41) with recurrent, asymptomatic prostate cancer were randomized among 2(More)
BACKGROUND The prevalence of chronic kidney disease (CKD) in patients with upper tract urothelial carcinoma (UTUC) is poorly defined, both before and after nephrouretectomy. Although multimodal treatment paradigms for UTUC are under-developed, this has important implications on patients' ability to receive cisplatin-based combination chemotherapy (CBCC). (More)
Relatively little is known about prostate cancer patients' information seeking after diagnosis, how they use such information in making a treatment decision, or what role information plays in adjusting to quality-of-life issues posttreatment. This research sought to explore some of these issues by examining prostate cancer patients' information seeking and(More)
OBJECTIVES To analyze the treatment outcomes of patients with micropapillary bladder cancer (MPBC). MPBC is a rare variant of urothelial carcinoma with aggressive clinical behavior. Radical cystectomy is considered the standard approach for treatment of patients with localized disease; however, the role of perioperative systemic therapy has been poorly(More)
