The chemokine receptor CXCR4 and CD133, putative stem cell markers, were previously described in renal cancer (RCC). To evaluate the biological and prognostic role of CD133 and CXCR4 in RCC the expression was evaluated through qPCR and immunoblotting in human renal cancer cell lines (786-O, A498, ACHN, CAKI-1, SN12C, TK10, UO31) and patients biopsies. Renal(More)
CXCR4 is a chemokine receptor implicated in the metastatic process. The CXCR4 ligand, CXCL12, was shown to bind also the CXCR7 receptor, a recently deorphanized chemokine receptor whose signalling pathway and function are still controversial. This study was conducted to determine patients clinic-pathological factors and outcome according to the expressions(More)
We report results of intraarterial chemotherapy (IAC) in patients with advanced unresectable (T4, N0-3, MO) squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) of the oral cavity, oropharynx, or facial skin, given through a subcutaneously transposed external carotid artery by a fine gauge needle. Forty patients entered the study and 39 were(More)
Intratumoral injections of a replication-incompetent adenovirus (Ad) expressing melanoma differentiation-associated gene-7/interleukin-24 (Ad.mda-7), a secreted cytokine displaying cancer-selective, apoptosis-inducing properties, profoundly inhibits prostate cancer (PC) growth in immune-incompetent animals. In contrast, Ad.mda-7 is ineffective in PCs(More)
Solitary metastases to the small bones and/or to the soft tissue of the hands and feet (acrometastases) are rare. We report a case of renal cell carcinoma (RCC) with big toe metastasis revealed before the primary tumor became apparent. The best treatment for a single metastasis is always surgical excision, regardless of the lesion being synchronous or(More)
Cadmium, a widespread toxic pollutant of occupational and environmental concern, is a known human carcinogen. The prostate is a potential target for cadmium carcinogenesis, although the underlying mechanisms are still unclear. Furthermore, cadmium may induce cell death by apoptosis in various cell types, and it has been hypothesized that a key factor in(More)
PURPOSE The quest for prognostic molecular markers in prostatic carcinoma is still in progress. Many proteins have already been screened by immunohistochemistry with the aim to find the most reliable indicator of progressive disease. In this study, we evaluated the expression of pRb2/p130, p107, p27(kip1), p53, mdm-2, and Ki-67 (MIB-1) by(More)
OBJECTIVES To prospectively evaluate the outcome of radical retropubic prostatectomy using three different techniques of vesicourethral anastomosis (VUA), with a different number of sutures used during this surgical step. METHODS Three groups of patients who had undergone nerve-sparing radical retropubic prostatectomy were compared. Overall, 90 patients(More)
PURPOSE We determine the value of dynamic sentinel node biopsy for staging squamous cell carcinoma of the penis. MATERIALS AND METHODS During a period of 2 years 17 patients with penile cancer was performed after lymphoscintigraphy pre and intraoperatively with gamma ray detection probe at biopsy of the sentinel node with the aid of perilesional(More)
