Renal cell carcinoma (RCC) in a kidney allograft is rare. We report the successful diagnosis and treatment of a de novo RCC in a nonfunctioning kidney transplant 20 years after engraftment. A 54-year-old man received a kidney transplant from his mother when he was 34 years old. After 10 years, chronic rejection resulted in graft failure, and the patient became hemodialysis-dependent. Intravenou...

PURPOSE To evaluate the influence of perinephric fat infiltration and tumor size on survival of patients with renal cell carcinoma (RCC). MATERIALS AND METHODS We have retrospectively reviewed the records of 338 consecutive patients with pT1-3aN0M0 RCC, including 275 pT1-2 and 63 pT3a tumors, who underwent open partial or radical nephrectomy between 1995 and 2008. Univariate and multivariate ...

PURPOSE The aims of this study were to evaluate the clinical significance and potential prognostic value of pregnancy up-regulated non-ubiquitous calmodulin kinase (PNCK) in clear cell renal cell carcinoma (ccRCC) patients. MATERIALS AND METHODS The expression of PNCK mRNA was determined in 24 paired samples of ccRCCs and adjacent normal tissues using real-time RT-PCR. The expression of PNCK ...

BACKGROUND The prognostic significance of preoperative thrombocytosis (TC) in renal cell carcinoma (RCC) is not without some debate. The aim of the present multi-institutional study was to determine the association of preoperative TC with the clinicopathological features and prognosis of localized RCC patients who underwent surgery in a large cohort. METHODS A study involving 8 institutions, ...

The present study aims to evaluate the impact of tumor microRNA-125b (miR-125b) on recurrence and survival of patients with clear-cell renal cell carcinoma (ccRCC) following surgery. We retrospectively enrolled 276 patients (200 in the training cohort and 76 in the validation cohort) with ccRCC undergoing nephrectomy at a single institution. Clinicopathologic features, cancer-specific survival ...

Currently, most renal masses are detected incidentally while still small in size because of the widespread use of radiological imaging, and most pheochromocytomas are localized in the adrenal glands as unilateral lesions. A 5 × 4-cm right adrenal mass and a 19 × 13-mm exophytic left renal mass were synchronously detected by contrast enhancement on computed tomography and magnetic resonance imag...

Renal tumours constitute 2.5% of all malignancies and are among the 10 most common malignancies in the UK. Most of these are renal cell carcinomas (RCC) of various subtypes. Although historically RCC has been shown to be resistant to radiotherapy and chemotherapy, recent data suggest that the use of biological treatments, such as adjuvants, may be beneficial in patients with disease that has pr...

PURPOSE To describe an entirely laparoscopic technique for excising a recurrence of local renal cell carcinoma (RCC). MATERIALS AND METHODS The patient is placed in a full flank position. A 10-mm trocar is inserted using Hasson's technique with three additional ports in the upper abdomen. After lysis of adhesions, the psoas muscle, ureteral and gonadal vein remnants, inferior vena cava or aor...

Aim: We aimed to study the role of CKAP4 in clear cell renal cell carcinoma (ccRCC), which is not reported previously. Method: In silico exploration and validation using immunohistochemistry in ccRCC samples were used to identify the impact of CKAP4 expression on clinicopathological parameters. In vitro and in vivo studies were carried out to recapitulate the role of CKAP4 in ccRCC cell lines a...

PURPOSE To explore the association of body mass index (BMI) and comorbidity with renal function after nephrectomy. MATERIALS AND METHODS We retrospectively analyzed 263 patients submitted to partial or radical nephrectomy from 2000-2013. Variables assessed included BMI, Charlson Comorbidity Index (CCI), race, tobacco use, tumor histology, surgical approach, Fuhrman nuclear grade, and tumor (T...
