Significant advances in molecular medicine have made renal cell carcinoma (RCC) the prototype solid organ malignancy for targeted medical cancer treatment. Theseis new options have made it possible to prolong the life of patients with metastatic disease. However, we are far away from thoroughly understanding the molecular processes of RCC development let(More)
PURPOSE Epithelial-mesenchymal transition enhances tumor cell motility and has a critical role in invasion and metastasis in a number of carcinomas. A set of transcription factors acts as a master regulator of the epithelial-mesenchymal transition process. To our knowledge it is unknown whether epithelial-mesenchymal transition is important for clear cell(More)
Anomalies of the fetal urachus are rare. Normally, the postnatal urachus presents as a fibrous band extending from the bladder to the umbilicus. Urachal cysts may occur in postnatal life. Spontaneous perforation of urachal cysts is a very rare condition, which clinically may not be distinguishable from other acute abdominal conditions. We report a case of a(More)
Ovarian type surface epithelial carcinomas of the testis and paratestis are rare. The most frequent form is the serous subtype while only a few cases of the mucinous subtype have been reported in the literature. A 67-year-old patient with a mucinous ovarian type surface carcinoma of the testis is presented. The histopathological and immunohistochemical(More)
The recent developments in the medical treatment of metastatic renal cell carcinoma have raised the question of the neoadjuvant use of targeted therapies in locally advanced renal tumours. Evidence at the level of case reports suggests that down-sizing of large renal carcinomas is feasible and small surgical series have so far shown that later surgical(More)
OBJECTIVE The initial objective of this renal cancer study was to identify gene sets in clear cell renal cell carcinoma (ccRCC) to support grading of ccRCC histopathology. MATERIALS AND METHODS Preselected ccRCC tumor tissues of grade 1 (G1, n = 14) and grade 3 (G3, n = 15) as well es 14 normal kidney tissues thereof were subjected to microarray(More)
INTRODUCTION The regulation proteins retinoblastoma protein (pRb) and p16 play an important role in the cell cycle as tumor suppressors. pRb is the main substrate for the function of cyclin-dependent kinases during the cell cycle in the transition from G(1) to S phase. In this study, the immunohistochemical expression of pRb and p16 in renal cell carcinoma(More)
OBJECTIVE To improve the workflow for standardizing the statistical interpretation provides an opportunity for the analysis of gene expression in clear cell renal cell carcinoma (ccRCC). RCC as a solid tumour entity represents a very suitable tumour model for such investigations. Although it is possible to investigate expression profiles by microarray(More)
Injuries of the penis are uncommon but represent urological emergencies. We report 3 cases of penile trauma illustrating the diversity of penile injury presentation. Radiological investigations are only mandatory if there is any suspicion of a urethral injury. Primary surgical approach is recommended in cases of penile fracture or local wound infection. An(More)
AIM To evaluate the expression and prognostic value of RARRES1 at protein level in renal cell carcinoma (RCC). MATERIALS & METHODS Expression profile of RARRES1 was analyzed in 903 documented RCC followed by clinicopathological correlations and survival analysis. RESULTS RARRES1 expression was seen in 72.5% of RCC. A stronger RARRES1 expression was seen(More)
