The biological behavior and immunohistochemical features of feline renal cell carcinoma (RCC) have not been well characterized. In the present study, immunohistochemical examinations were performed in 12 feline cases of RCC. The RCC consisted of solid ( n = 2), solid-tubular ( n = 2), tubular ( n = 3), papillary ( n = 2), tubulopapillary ( n = 2), and sarcomatoid ( n = 1) type lesions. Of the cases with RCC, 1 developed metastatic disease and 6 cases had no evidence of recurrence at 80 to 2292 days after surgery...

Programmed death 1 (PD-1) and PD ligand 1 (PD-L1) inhibitors have shown activity in metastatic clear cell renal cell carcinoma (ccRCC). Data on the activity of these agents in patients with non-clear cell RCC (nccRCC) or patients with sarcomatoid/rhabdoid differentiation is limited. In this multicenter analysis, we explored the efficacy of PD-1/PD-L1 inhibitors in patients with nccRCC or sarcomatoid/rhabdoid differentiation. Baseline and follow-up demographic, clinical, treatment, and radiographic data were collected...

Sarcomatoid carcinoma is a highgrade rare malignant tumor with both epithelial and mesenchymal components. Sarcomatoid carcinoma in the upper urinary tract is very rare. We reported here a case of sarcomatoid carcinoma of renal pelvis with osteosarcomatous differentiation, with involvement of the ureter and renal parenchyma in a 68-year-old female. Histologically, predominant pleomorphic spindle cell sarcoma component with osteoid production and urothelial carcinoma component with in situ areas were identified...

Fumarate hydratase-deficient renal cell carcinoma (FH-RCC) is a rare, aggressive RCC type, originally described in the setting of hereditary leiomyomatosis and renal cell carcinoma (HLRCC) syndrome which is defined by germline FH gene inactivation. Inactivation of components of the SWI/SNF chromatin remodelling complex is involved in renal medullary carcinoma (SMARCB1/INI1 loss), clear cell RCC (PBRM1 loss) and in subsets of dedifferentiated RCC of clear cell, chromophobe and papillary types (loss of different SWI/SNF components)...

Renal mucinous tubular and spindle cell carcinoma (MTSCC) is a rare, low-grade renal epithelial neoplasm. MTSCC has a lower malignant potential and shows relatively good prognosis, but can be difficult to distinguish from other renal cell carcinoma (RCC) subtypes. Here, we report two cases of metastatic and recurrent renal MTSCC diagnosed after long-term follow-up. Case 1 was a 79-year-old man with a history of macroscopic hematuria in whom a right kidney mass was detected and diagnosed as RCC (cT3bN0M0). After a radical nephrectomy, microscopic findings showed that the tumor consisted of spindle cells arranged in tubular patterns embedded in sarcomatoid tissues ; we diagnosed it as unclassified RCC with sarcomatoid differentiations (pT3aN0M0)...

BACKGROUND: The treatment of advanced or metastatic renal cell carcinoma (RCC) has drastically changed since the approval of immune checkpoint therapy. Nivolumab is a treatment option for patients with metastatic RCC, previously treated with targeted antiangiogenic therapy. The efficacy of nivolumab for patients with RCC was established by the Checkmate 025 clinical trial. Chromophobe RCC (CRCC) represents around 5% of RCC cases, but non-clear cell RCC (non-ccRCC) subtypes were excluded from the Checkmate 025 clinical trial...

BACKGROUND: The G protein-coupled bile acid receptor (TGR5) is a cell surface receptor which induces the production of intracellular cAMP and promotes epithelial-mesenchymal transition in gastric cancer cell lines. TGR5 is found in a wide variety of tissues including the kidney. However, the patterns of TGR5 expression have not been well characterized in physiologic kidney or renal neoplasms. We explore the expression of TGR5 in benign renal tissue and renal neoplasms and assess its utility as a diagnostic marker...

Sameera Rashid, Mohammed Akhtar
Sarcomatoid variant of urothelial carcinoma (SVUC) of the renal pelvis is a rare entity. To the best of our knowledge, around 25 cases of this neoplasm have been reported in the literature to date, most of which were of high stage. The inferior vena cava tumour thrombus, which is a hallmark of renal cell carcinoma (RCC), may rarely be found in urothelial carcinoma of renal pelvis. In this report, a case of SVUC associated with tumour extension to inferior vena cava is documented. This association has been encountered in only one previously reported case...

Inflammation-based prognostic scores are useful for predicting survival in various cancers. Here, we aimed to determine the most useful inflammation-based prognostic score for predicting survival in patients with metastatic renal cell carcinoma undergoing cytoreductive nephrectomy. We retrospectively analyzed the data of 152 patients who underwent cytoreductive nephrectomy for metastatic renal cell carcinoma between 1986 and 2015. In the multivariate stepwise analysis, the combination of age, Memorial Sloan-Kettering Cancer Center score, histology, sarcomatoid change, clinical nodal stage, brain metastasis, and liver metastasis was a significant predictor for survival (Harrell's concordance index [c-index]: 0...

Occasionally, renal cell carcinoma (RCC) with renal vein extension spreads against the flow of blood within vein branches into the kidney, forming multifocal nodules throughout the renal parenchyma. These foci are not regarded as multiple tumors but rather reverse spread of tumor along the venous system. This intravascular spread has previously been reported in clear cell RCC and RCC unclassified. However, to our knowledge, this has never been reported in chromophobe RCC. Chromophobe RCC is a unique histologic subtype of renal cancer, generally thought to have less aggressive behavior...

BACKGROUND: Clear-cell renal-cell carcinoma (ccRCC) is characterized by loss of a functional Von Hippel-Lindau (VHL) protein. We investigated the potential of 3 single nucleotide polymorphisms (SNPs) in VHL as biomarkers in metastatic ccRCC (m-ccRCC) patients treated with vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors (TKIs). PATIENTS AND METHODS: We genotyped 3 VHL SNPs in 199 m-ccRCC patients: rs1642742 T > C, rs1642743 A > G, and rs1678607 C > A...

We report the case of a 49-year-old white man with a chromophobe renal cell carcinoma associated with sarcomatoid differentiation, an uncommon yet an aggressive form of dedifferentiated renal cell carcinoma. In opposite to the conventional renal cell carcinoma, which may not always demonstrate avid FDG activity, the sarcomatoid differentiated chromophobe renal cell carcinoma shows intense FDG uptake on PET. This case highlights the role of FDG PET/CT in staging and restaging this type of rare renal cell carcinoma...

Objective: Renal cell carcinomas (RCCs) include about 2% of adult neoplasms and 90-95% of all renal tumors. Mostly, it is possible to distinguish RCC subtypes using hematoxylin-eosin staining. However, overlapping morphologic features cause some difficulties in making a precise diagnosis. In order to render an accurate diagnosis, additional methods such as immunohistochemical staining for c-kit have been recommended. In this study, we aimed to investigate c-kit gene expression in various subtypes of RCC...

Hereditary leiomyomatosis and renal cell carcinoma syndrome is characterized by an increased risk of agressive renal cell carcinoma, often of type 2 papillary histology, and is caused by FH germline mutations. A prominent eosinophilic macronucleolus with a perinucleolar clear halo is distinctive of hereditary leiomyomatosis and renal cell carcinoma syndrome-associated renal cell carcinoma according to the 2012 ISUP and 2016 WHO kidney tumor classification. From an immunohistochemistry perspective, tumors are often FH-negative and S-(2-succino)-cysteine (2SC) positive...

INTRODUCTION: Metastatic renal cell carcinoma (RCC) with a sarcomatoid component is a rare disease associated with a poor prognosis. We report the outcomes of 47 patients with metastatic sarcomatoid RCC (SRCC) treated with different modalities including chemotherapy, tyrosine kinase inhibitors, or immunotherapy over 2 decades in a French cancer center. Furthermore, we assessed the validity of prognostic scores in this subset of RCC. PATIENTS AND METHODS: Patients were retrospectively identified from the database of the pathology department of the University Hospital of Strasbourg...

We developed and validated an architecture-based grading for clear cell renal cell carcinoma (ccRCC) in an observational retrospective cohort study including 506 tumors (principal cohort, n=254; validation cohort, n=252). Study endpoints were disease-free survival (DFS) and cancer-specific survival (CSS). Relationships with outcome were analyzed using Harrell concordance index, time-dependent receiver operating characteristic curve, area under curve, and Cox regression model. An architecture-based grading was devised on positive likelihood ratio (LR+) for DFS at 50 months as follows: grade 1 (LR+<0...

Sarcomatoid renal cell carcinoma (sRCC) is a highly aggressive form of dedifferentiated renal cell carcinoma. We report a 62-year-old man who presented with respiratory symptoms and a lung mass on chest computed tomography (CT). The patient underwent positron emission tomography/computed tomography (PET/CT) with 18 F-fluorodeoxyglucose (18 F-FDG) and was found to have extensive metastatic disease. Based on the history and imaging findings, there were possible primary malignancies, including bronchogenic carcinoma, melanoma, or an aggressive lymphoma...
