The therapeutic options for patients with metastatic renal cell carcinoma (mRCC) have completely changed during the last ten years. With the sequential use of targeted therapies, median overall survival has increased in daily practice and now it is not uncommon to see patients surviving kidney cancer for more than four to five years. Once treatment fails with the first line targeted therapy, head to head comparisons have shown that cabozantinib, nivolumab and the combination of lenvatinib plus everolimus are more effective than everolimus alone and that axitinib is more active than sorafenib...

OBJECTIVES: Approximately 1 % of all malignant solid tumours of the head and neck area are metastases from primary tumours beneath the clavicles. The aim of this study was to analyse the distribution of primary tumours since meta-analyses might have been biased due to the usually extraordinary character of case reports. MATERIALS AND METHODS: All patient files from 1970 to 2012 from the Oral and Maxillofacial Surgery unit at a University Hospital were analysed regarding the existence of metastases to the head and neck area from distant primaries...

A 78-year-old man was treated with laparoscopic partial nephrectomy for a 4 cm tumour in the lower pole of the left kidney. The patient was discharged 2 days postoperatively. Preoperatively there was no sign of metastasis; the pathology indicated complete removal of the tumour, a renal cell carcinoma. 53 days postoperatively the patient had acute onset of rectal bleeding. A colonoscopy revealed necrosis and three clips on the wall of the colon corresponding to where the descending colon passes over the left kidney...

A 65-year-old female presented to clinic requesting follow up for a history of right robotic partial nephrectomy done at an outside institution 2 years prior. Initial pathology demonstrated a grade 2/4 3.4 cm clear cell renal cell carcinoma with negative margins. There was no tumor necrosis, sarcomatoid differentiation, or lymphovascular invasion. High quality follow up imaging initially revealed a pseudoaneurysm in the central portion of the right kidney. The patient was sent to interventional radiology for angioembolization...

Horseshoe kidney is the most common renal fusion anomaly found in about 0.15% to 0.25% of the population. Renal cell carcinoma associated with a horseshoe kidney has been described in fewer than 200 cases. Its incidence and prognosis seems to be not different from those of the general population, but surgical management may be challenging due to unique anatomic features of horseshoe kidneys, such as highly variable vasculature. We report a case of a 69-year-old male with an incidental 48-mm solid mass in the left moiety of a horseshoe kidney, successfully treated by retroperitoneoscopic partial nephrectomy...

A 68-year-old woman presented with visible haematuria. Ultrasonography and triphasic CT revealed a 2.6 cm mass in the lower pole of the left kidney. A biopsy suggested low-grade renal cell carcinoma. Radical nephrectomy was performed and revealed an epithelioid angiomyolipoma. At year 3, the patient developed ductal carcinoma of the right breast and underwent a wide local excision and sentinel lymph node biopsy followed by chemotherapy and radiotherapy. 4 months later, she was noted to have a 1.6 cm nodule in the middle lobe of her right lung...

OBJECTIVE: To identify miRNA characteristic of metastatic clear cell renal cell carcinoma (ccRCC) and those indicative of cancer specific survival in nephrectomy and biopsy specimens. We also sought to determine if a miRNA panel could differentiate benign from ccRCC tissue. MATERIALS AND METHODS: RNA was isolated from nephrectomy and kidney biopsy specimens (n=156; n=46 respectively). Samples were grouped: benign, non-progressive and progressive ccRCC. MiRNA were profiled by microarray and validated by qRT-PCR...

In the past few years, metastatic renal cell carcinoma prognosis was improved by the development of molecular targeted therapies (TTs). At the metastatic stage, the tolerance to treatment is a major concern, not only because of the challenge of the efficacy/toxicity ratio improvement but also because of the importance of an optimal adherence to oral treatments. The present case series relates the issues of dealing with uncommon and sometimes never described side effects of sunitinib and sorafenib. The first case report deals with grade 3 vomiting during hemodialysis with concurrent administration of sunitinib...

Clear cell renal cell carcinomas (ccRCC) show a broad range of clinical behavior, and prognostic biomarkers are needed to stratify patients for appropriate management. We sought to determine whether long intergenic non-coding RNAs (lincRNAs) might predict patient survival. Candidate prognostic lincRNAs were identified by mining The Cancer Genome Atlas (TCGA) transcriptome (RNA-seq) data on 466 ccRCC cases (randomized into discovery and validation sets) annotated for ~21,000 lncRNAs. A previously uncharacterized lincRNA, SLINKY (Survival-predictive LINcRNA in KidneY cancer), was the top-ranked prognostic lincRNA, and validated in an independent University of Tokyo cohort (P=0...

The aim of this study was to evaluate intermediate-term results after microwave ablation (MWA) of renal tumours and determine the association of RENAL and modified RENAL (mRENAL) scores with oncological outcomes and complications. In May 2008-September 2014, 58 patients affected by early-stage RCC (renal cell carcinoma; T1a or T1b) were judged unsuitable for surgery and treated with percutaneous MWA. Follow-up was performed with contrast-enhanced computed tomography at 1, 3, 6, 12 and 24 months after the procedure...

Clear cell Renal Cell Carcinoma (ccRCC) causes over 13,000 deaths each year, and about 20,000 new cases/year in Europe. In most cases, the causes are unknown and, most importantly, there are no reliable biomarkers for the diagnosis and prognosis of this disease. The search for sensitive biomarkers for early diagnosis and prognosis of clear cell Renal Cell Carcinoma (ccRCC) is currently a fast growing field. We carried out proteomics analysis of 93 urinary samples of healthy subjects (HS) and patients affected by ccRCC, prostate cancer (PCa) and chronic kidney disease (CKD), that was able to successfully distinguish each group...

Renal cell carcinoma (RCC) management has undergone a major transformation over the past decade; immune checkpoint inhibitors are currently undergoing clinical trials and show promising results. However, the effectiveness of immune checkpoint inhibitors in patients with metastatic RCC (mRCC) is still limited. Lycorine, an alkaloid extracted from plants of the Amaryllidaceae family, is touted as a potential anti-cancer drug because of its demonstrative growth inhibition capacity (induction of cell cycle arrest and inhibition of vasculogenic mimicry formation)...

There have been no recurrences or metastases of clear cell papillary renal cell carcinoma (CCPRCC) in 268 reported cases with follow-up in the English-language literature. We identified all our cases of CCPRCC (1990-2013), reviewing all cases that preceded the formal designation of the entity. Immunohistochemical stains were performed on 32 cases during their initial workup. In addition, stains for carbonic anhydrase IX and cytokeratin 7 were performed on 2 cases, one with atypical follow-up and the other with a more compact morphology, although not performed initially...

Arctigenin (ARG) is famous in its abundant pharmacological activity. However, many researches in it entered the bottleneck period because of its poor water solubility. The derivatives of ARG have been synthesised with five amino acids which have t-Butyloxy carbonyl (BOC) as a protective group. We examined the effects of removing BOC. The results showed that the amino acid derivatives without protective group have better water solubility and nitrite-clearing ability than ARG. Based on these results, ARG6' and ARG9' were selected at a dosage of 40 mg/kg to evaluate their antitumour activity...

PURPOSE: The aim of this study was to determine the effect of preoperative chronic kidney disease (CKD) on the prognosis of patients with upper urinary tract urothelial carcinoma (UTUC) who had undergone radical nephroureterectomy (RNU). RESULTS: The median follow-up period was 31.1 months (interquartile range: 16.2-55.7 months). Among the study patients, 224 patients in the non-CKD group were selected via propensity score matching. The median recurrence-free, cancer-specific, and overall survival were significantly shorter for patients with preoperative CKD than for non-CKD patients (p = 0...

The accuracy of renal mass biopsy to diagnose malignancy can be affected by multiple factors. Here, we investigated the feasibility of Raman spectroscopy to distinguish malignant and benign renal tumors using biopsy specimens. Samples were collected from 63 patients who received radical or partial nephrectomy, mass suspicious of cancer and distal parenchyma were obtained from resected kidney using an 18-gauge biopsy needle. Four Raman spectra were obtained for each sample, and Discriminant Analysis was applied for data analysis...

Renal transplantation has been associated with a significantly increased risk of developing cancer, including bladder neoplasia, with urothelial carcinoma being the most frequent type of bladder cancer. Bladder paraganglioma, also referred to as extra-adrenal pheochromocytoma, is a rare but severe condition that may cause a severe hypertensive crisis during handling and mobilization of the tumor. We herein present the case of a 67-year-old kidney transplant recipient with a bladder polyp consistent with paraganglioma of the bladder...

Cases of renal cell carcinoma (RCC) presenting as a simple cyst are extremely rare. We herein report the case of a patient with RCC diagnosed as a simple renal cyst preoperatively. A 39-year-old female patient presented with abdominal pain for 3 months. Ultrasonography and contrast-enhanced computed tomography revealed a simple cyst in the left kidney. The patient underwent laparoscopic decortication of the renal cyst. Biochemical analysis of the cystic fluid revealed unusually low levels of potassium, sodium, calcium and glucose, and the histological examination of the floor of the cyst indicated malignancy...
