Chromosomal losses resulting in a marked hypodiploidy are a specificity of chromophobe renal cell carcinoma (ChRCC), the third most frequent type of kidney cancer. Its detection is useful in challenging cases. However some ChRCC, especially the eosinophilic variant, do not exhibit hypodiploidy and deserve to be better explored.

Metastatic clear cell renal cell carcinomas (mRCC) over-express the vascular endothelial growth factor (VEGF). Hence, the anti-VEGF antibody bevacizumab/Avastin (BVZ) combined with interferon alpha (IFN) was approved for the treatment of mRCC. However, approval was lost in July 2016 due to the absence of sustained efficacy.

A 72-year-old Caucasian man incurring a prostate hypertrophy presented with a right forearm nodule, the growth of which appeared to parallel the rise in his blood prostate-specific antigen (PSA) level. Echographic examination was consistent with a median-nerve schwannoma, and was confirmed upon magnetic resonance imaging (MRI). Excision of the nodule was readily performed without significant neural damage, and its schwannoma nature was confirmed upon immunohistochemistry analysis.

Article Synopsis
  • The study compared outcomes of dual kidney transplantation (DKT) and single kidney transplantation (SKT) using grafts from expanded criteria donors in patients aged 65 and older, focusing on surgical complications.
  • The analysis included 39 DKT and 155 SKT cases, revealing no significant difference in early surgical revisions, but a higher incidence of venous graft thrombosis after DKT.
  • Additionally, DKT patients had a significantly higher glomerular filtration rate (GFR) 24 months post-transplant, suggesting that DKT can be an effective option for addressing kidney graft shortages in elderly recipients despite the increased risk of certain complications.

Introduction: Cancer Committee of the French Association of Urology (CCAFU) conducted a literature review concerning the follow-up of urothelial carcinomas and provides recommendations for monitoring.

Material And Methods: A bibliographic research in French and English using PubMed was carried out from 1990 to 2014 using the keywords "urothelial carcinoma", "follow-up", "prognosis", and "recurrence".

Results: Rhythm and tools of follow-up (cytology, endoscopy, CT-urography) for non muscle invasive bladder cancer (NMIBC) have to be adjusted to the recurrence and progression risk defined by the EORTC tables.

Urothelial bladder cancer (UBC) is rare in young patients and as a result little information as to tumor type and clinical course are available. We present clinicopathological data of a large series of patients less than 40 years with bladder carcinoma. We included in this retrospective study covering the period from 1992 to 2013 patients less than 40 years with a first diagnosis of bladder cancer.

Introduction: Due to its technical ease and greater precision Robotic Assisted Laparoscopic radical Prostatectomy (RALP) allows a better preservation of the neurovascular bundles, thereby improving functional outcomes. The intrafascial dissection has been proposed to allow a more complete preservation of these bundles. However, this technique harbors a high rate of positive surgical margins, justifying another trend: the interfascial approach.

Article Synopsis
  • The study examined the occurrence and characteristics of prostate cancer (PCa) found incidentally in patients who underwent radical cystoprostatectomy (RCP) for bladder cancer, analyzing data from 4,299 male patients from 1996 to 2012.
  • Among the patients, 21.7% were found to have PCa, with the majority being at an early stage (90.1% organ-confined).
  • During follow-up, only 1.9% experienced a recurrence of PCa, and no patients died from it, highlighting a low risk associated with incidental PCa diagnosis in this context.
