Sarcomatoid renal cell carcinoma (sRCC) is not currently thought to represent a distinct histologic subtype of renal cell carcinoma (RCC), but represents a "final common dedifferentiation pathway." It occurs in ~16% of advanced RCCs. Sarcomatoid and rhabdoid (S/R) renal cell carcinoma (RCC) are among the most aggressive forms of kidney cancer 1,2.Sarcomatoid and rhabdoid features represent forms of dedifferentiation of RCC . Epub 2015 Jun 8. link to original article PubMed NCT00556049
Preoperative identification of the subtype and prognostic factors of SRCC would be of great clinical significance. Sarcomatoid Renal Cell Carcinoma: SNOMED CT: Renal cell carcinoma, spindle cell (128668003); Renal cell carcinoma, sarcomatoid (128668003) Definition. Several efforts have been conducted to break down the molecular profile of sarcomatoid RCC and investigate different targeted therapeutic approaches. Materials and methods: For this meta-analysis, we searched MEDLINE . On imaging, they are generally large masses, with irregular contours, and malignant-appearing, but do not have specific imaging features. Many of these tumors are unresectable at presentation, and are thus potential candidates for FNA. Preoperative identification of the subtype and prognostic factors of SRCC would be of great clin-ical significance. sRCC develops out of advanced RCC and typically presents as a large necrotic mass with >50% having metastatic disease at presentation. Sarcomatoid and rhabdoid (S/R) renal cell carcinoma (RCC) are among the most aggressive forms of kidney cancer 1,2.Sarcomatoid and rhabdoid features represent forms of dedifferentiation of RCC . Among 118 sarcomatoid RCC patients and 92 non-sarcomatoid clear cell renal cell carcinoma patients, Kawakami et al. However, little is known about the outcomes of patients with brain metastasis (BrM) treated with I+N. Although once a separate histologic category, sarcomatoid renal cell carcinoma is no longer considered a separate tumor type because it can occur with all histologic subtypes.
The bone scan was clear, but the lung scans showed metastatic sarcomatoid renal cell carcinoma in both lungs. 141,142 Nevertheless, more tumors are being identified at a lower stage and these patients may have a . Choueiri TK, Heng DYC, Lee JL et al. Renal cell carcinoma of any type exhibiting at least focal sarcomatoid/spindle cell differentiation; Alternate/Historical Names. Computed tomographic (CT) and angiographic findings in 14 patients (eight men, six women, aged 30-72 years) with sarcomatoid renal cell carcinoma (SRCC) and various types of renal sarcoma are described. It is an adenocarcinoma making up 85% of all renal malignancies. Use TNM staging for all renal carcinomas at present Remember that it is based predominantly on clear cell carcinomas 2015 Oct 1;121(19):3435-43. Renal cell carcinoma (RCC) is responsible for 2-3% of all adult malignancies and is one of the fatal tumors of the renal system. Sarcomatoid renal cell carcinoma (SRCC) is a form of dedifferentiated renal cell carcinoma (RCC) with aggressive behavior. Clin Genitourin Cancer. I was to receive chemotherapy as an in patient with the drip to last 18 hours per day for 4 days per cycle. Sarcomatoid renal cell carcinoma. These tumours are not recognized as a distinct type of renal cell carcinoma; they are classified by the non-sarcomatous component. A sarcomatoid component can occur in all histologic subtypes of renal cell carcinoma (RCC) and indicates an aggressive tumor.
Sarcomatoid Renal Cell Carcinoma: Biologic Behavior, Prognosis, and Response to Combined Surgical Resection and Immunotherapy By Thomas Cangiano, Joseph Liao, John Naitoh, Frederick Dorey, Robert Figlin, and Arie Belldegrun Purpose: Sarcomatoid variants of renal cell carci-noma (RCC) are aggressive tumors that respond poorly to immunotherapy. The aim of this paper is to present a rare case of a 45-year-old male patient with SRCC. Mainly symptomatic and discovered at an advanced stage, it has a poor prognosis, requiring multidisciplinary management quickly and correctly.
This study showed that the PD-L1 H-score of sarcomatoid RCC (mean, 3.7; range, 0-192 .
Sarcomatoid transformation is a microscopically identified feature of RCC accounting for 5% of all RCCs [2]. An immunohistochemical study of 18 cases.
Carcinoma, Renal Cell Preferred Term. Of 920 patients with histologically confirmed renal cell carcinoma (RCC) seen at University of Texas M. D. Anderson Hospital over a 10-year period, 44 (4.8%) had the sarcomatoid variant. Sarcomatoid renal cell carcinoma can occur in the setting of all histological subtypes of kidney cancer. It is considered to be an aggressive variant with average survival of less than 12 months.

Chromosomal translocation (X;18) analysis returned positive and synovial sarcoma was diagnosed. In this study, we sought to determine the epidemiologic factors and therapeutic interventions affecting survival in this rare disease using a large national database. 2004; 28 :435-441. doi: 10.1097/00000478-200404000-00002. Renal cell carcinoma (RCC), including sarcomatoid RCC, has the ability to metastasize to various locations including the lung, bone, lymph nodes, and liver. In the United States, cancers of the kidney and renal pelvis are the sixth most common type of cancer and an estimated 63,990 new patients will be diagnosed in 2017 .Renal cell carcinoma (RCC) is the most common cancer of the kidney and it consists of multiple histologic subtypes .Sarcomatoid transformation in RCC is characterized by a transformative growth pattern of the epithelial neoplasm . (Figure 2). Delahunt B (1999) Sarcomatoid renal carcinoma: the final common dedifferentiation pathway of renal epithelial malignancies. The yellow background of the tumor is consistent grossly with a clear cell renal cell carcinoma. Sarcomatoid renal cell carcinomas (sRCC) may develop when one of the more common histologic subtypes of renal cell carcinoma degenerates into a sarcoma. The most common metastatic site was the lung (67%), followed by lymph nodes (LN) (62% . Sarcomatoid renal cell carcinoma (sRCC) represents a rare form of renal cell carcinoma marked by an aggressive biology, poor prognosis and little benefit from anti-angiogenic targeted therapy. It is characterized by a high propensity for primary metastasis and limited therapeutic options due to its relative resistance to established systemic targeted therapy. We studied 2381 patients treated with radical nephrectomy for RCC between 1970 and 2000. INTRODUCTION. 60 TABLE 1. No cellular or genetic biomarker for the sarcomatoid variant has yet been discovered. The combination of ipilimumab plus nivolumab (I+N) has greatly improved outcomes in patients with intermediate or poor-risk untreated metastatic renal cell carcinoma (mRCC). Eleven cases of sarcomatoid renal cell carcinoma were studied to determine the relative frequency of various subtypes of renal cell carcinoma that may be associated with sarcomatoid trans-formation. We present here a case of a 68-year-old male with known stage IV sarcomatoid renal cell carcinoma who came to the emergency department (ED) complaining of shortness of breath. At the time point of ICI treatment, 9.6%, 31.9% and 58.5% had one, two and three or more metastatic sites, respectively. of patients Percent Evaluated 920 100 Nonsarcomatoid 8 14 88.5 Sarcomatoid 44 4.8 Second malignancy with 62 6.7 During the period January I, 1973 to December 31, 1982, 1136 patients registered under the diagnosis RCC; 920 patients were (80.9%), evaluated and histologic study confirmed RCC. Renal cell carcinoma (RCC) represents 2-3% of all cancers [1]. Carcinosarcoma; Spindled carcinoma; Diagnostic Criteria. Background: Sarcomatoid Renal Cell Carcinoma (sRCC) is a rare disease found in approximately 5% of all RCCs.

Sarcomatoid renal cell carcinoma arising from a clear cell renal cell carcinoma (lower left). . Case Discussion. A search was performed to retrospectively identify all patients with mRCC treated with I+N in the Duke Cancer Institute . 1 It is not a distinct histologic entity; rather, it can be observed across all RCC subtypes, including clear-cell, papillary, chromophobe, unclassified, and collecting-duct carcinomas. Sarcomatoid transformation in renal cell carcinoma, so called sacromatoid RCC (sRCC), is associated with an aggressive behavior and a poor prognosis. Sarcomatoid features can be seen in all types of RCC and do not constitute a separate histologic type. These tumours are very aggressive and many patients present with disseminated disease. More promising results come from the recent therapeutic strategy based on immune checkpoint inhibitor (ICI) combinations. It is not a distinct clinicopathological entity and includes a diverse group of renal cell carcinomas which have been transformed from a lower to a higher grade. The authors show that, although sarcomatoid RCC has as common denominators with classic RCC in certain epidemiolo …
The tumour consisted of typical clear cells of renal cell carcinoma and spindle cells compatible with malignant fibrous histiocytoma (MFH). Urothelial (transitional cell) carcinomas of the renal pelvis account for approximately 8 percent of kidney tumors, and other parenchymal epithelial tumors, such as oncocytomas, collecting duct tumors, and renal sarcomas, are rare. The epithelial components in these tumors were subcategorized according to established histologic criteria into chromophobe carcinoma (n = 6 cases), clear cell carcinoma (n = 3), papillary . Represents a form of high grade transformation, not a distinct subtype of renal cell carcinoma. . Clear cell RCC (reported 5-8% incidence of sarcomatoid foci, in our experience it is less frequent) Papillary RCC (2-3% incidence) Chromophobe RCC (9% incidence) Collecting duct carcinoma (39% incidence) Staging.
