Background. The prognostic significance of the neutrophil-to-lymphocyte ratio (NLR) in nonmetastatic renal cell carcinoma (non-mRCC) is controversial, although NLR has been established as a prognostic factor in several cancers. The objective of our study was to assess the prognostic significance of preoperative NLR in non-mRCC, based on a large, multicenter cohort analysis. Methods. Totally, 1,284 non-mRCC patients undergoing surgery were enrolled from six institutions between 2000 and 2014. Recurrence-free survival (RFS) and cancer-specific survival (CSS) were calculated, and the prognostic significance of NLR was evaluated...

PURPOSE: To assess the prognostic significance of sarcomatoid differentiation for surgically treated metastatic renal cell carcinoma (mRCC). METHODS: Patients undergoing cytoreductive nephrectomy for mRCC in our center between 2006 and 2014 were included. All enrolled patients were separated into two groups according to the presence of sarcomatoid differentiation. Clinical and pathological variables were recorded. Student's t test or Chi-square test was applied to compare them...

BACKGROUND: VEGF-targeted therapy has become the mainstay of treatment for majority of mRCC patients. For most patients, benefit is short-lived and therefore treatment remains palliative in intent. HD IL2 is an effective immunotherapy treatment capable of durable remission in some patients but its unselected use has been difficult due to its modest response rate and considerable adverse effects. Using set pathology criteria as a selection tool in clinical practice, we have been able to show improved outcomes in our previous report...

We report a 55-year-old man presented with anemia and weakness, history of flank pain, hematuria and nephrotic syndrome. Spiral abdominopelvic computerized tomography (CT) scan showed multiloculated cystic mass (120 ×100 ×80 mm) in lower portion of left kidney with internal enhancing solid components and coarse peripheral calcifications. Radical nephrectomy of left kidney was done and biopsy confirmed renal cell carcinoma (RCC), papillary type, sarcomatoid foci, Fuhrman grade III. We assumed that, presence of nephrotic syndrome and paraneoplastic glomerulopathy leaded to heavy proteinuria in this case...

Clear cell renal cell carcinoma (ccRCC) is an aggressive tumor that is characterized in most cases by inactivation of the tumor suppressor gene VHL. The VHL/HIF/VEGF pathway thus plays a major role in angiogenesis and is currently targeted by anti-angiogenic therapy. The emergence of resistance is leading to the use of targeted immunotherapy against immune checkpoint PD1/PDL1 that restores antitumor immune response. The correlation between VHL status and PD-L1 expression has been little investigated. In this study, we retrospectively reviewed 98 consecutive cases of ccRCC and correlated PD-L1 expression by immunohistochemistry (IHC) with clinical data (up to 10-year follow-up), pathological criteria, VEGF, PAR-3, CAIX and PD-1 expressions by IHC and complete VHL status (deletion, mutation and promoter hypermethylation)...

PURPOSE: Clear cell renal cell cancers frequently harbor Von Hippel-Lindau gene mutations, leading to stabilization of the hypoxia-inducible factors (HIFs) and their target genes. In this study, we investigated the relationship between vascular endotelial growth factor (VEGF), HIF-1α, HIF-2α, p53 positivity, microvessel density, and Ki-67 rates with prognostic histopathologic factors (Fuhrman nuclear grade, stage, and sarcomatoid differentiation) and survival in clear cell renal cell carcinomas...

BACKGROUND: Staghorn calculi are well-established risk factors for recurrent urinary tract infections (UTIs) and subsequent renal deterioration. Less commonly, long-term urothelial irritation from a calculus may also pose a risk of malignant transformation. CASE PRESENTATION: A 77-year-old male with multiple medical comorbidities presented with a chronic right renal pelvic staghorn calculus and findings concerning for emphysematous pyelonephritis. He was subsequently taken to the operating room for a planned laparoscopic right nephrectomy...

A 59-year-old man who had undergone hemodialysis for 13 years was diagnosed with left renal cell carcinoma (RCC),cT1aN0M0,in 2010. He had a laparoscopic left nephrectomy,and the pathological diagnosis at that time was clear cell carcinoma,pT1a (multifocal). At 1 year after surgery,he was diagnosed with a left renal hilar lymph node metastasis and a new right RCC,cT1aN0M0. Consequently,he underwent a right nephrectomy and retroperitoneal lymph node dissection in 2012. Pathologic diagnosis by the current classification of the right renal tumor was acquired cystic disease-associated renal cell carcinoma (ACD-associated RCC),and that of the left hilar lymph node was metastatic RCC with sarcomatoid change...

BACKGROUND: Pazopanib is associated with increased progression-free survival (PFS) in clear-cell renal cell carcinoma (RCC) and has become a standard of care in this disease. The drug is used in metastatic non-clear-cell RCC, but data on outcomes in this setting are limited. PATIENTS AND METHODS: We conducted a retrospective data analysis of records of consecutive metastatic non-clear-cell RCC patients who received pazopanib in front-line and salvage settings between November 2009 and November 2012...

Sarcomatoid transformation, wherein an epithelioid carcinomatous tumour component coexists with a sarcomatoid histology, is a predictor of poor prognosis in clear cell renal cell carcinoma. Our understanding of sarcomatoid change has been hindered by the lack of molecular examination. Thus, we sought to characterize molecularly the biphasic epithelioid and sarcomatoid components of sarcomatoid clear cell renal cell carcinoma and compare them to non-sarcomatoid clear cell renal cell carcinoma. We examined the transcriptome of the epithelioid and sarcomatoid components of advanced stage sarcomatoid clear cell renal cell carcinoma (n=43) and non-sarcomatoid clear cell renal cell carcinoma (n=37) from independent discovery and validation cohorts using the cDNA microarray and RNA-seq platforms...

INTRODUCTION: Clear cell renal cell carcinomas (ccRCCs) are highly metastatic tumors with metastases detected at diagnosis (synchronous) or during follow-up (metachronous). To date, there have been no reports comparing primary ccRCC of patients with synchronous and metachronous metastases, who are different in terms of prognosis. Determining whether there is a phenotypic difference between these 2 groups could have important clinical implications. PATIENTS AND METHODS: In a retrospective consecutive cohort of 98 patients with ccRCC, 48 patients had metastases, including 28 synchronous and 20 metachronous presentations, with a follow-up of 10 years...

Pulmonary sarcomatoid carcinoma (PSC) is a rare malignant cancer composed of sarcoma and sarcoma-like elements with spindle or giant cell features. We report the case of a 60-year-old male with past medical history of right renal cell carcinoma 2 years earlier. Apulmonary nodule was detected in the left upper lobe, 23 months after nephrectomy. Systemic positron emission tomography-computerized tomography (PET-CT) revealed one high metabolic mass shadow in the left upper lobe. Chest CTscan with contrast revealed a left upper lobe mass (2...
