Sarcomatoid features can be seen in all types of RCC and do not constitute a separate histologic type. Background: 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. 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 renal cell carcinoma: a case report and ... Renal cell carcinomas (RCCs), which originate within the renal cortex, constitute 80 to 85 percent of primary renal neoplasms. Sarcomatoid Renal Cell Carcinoma: A Comprehensive Review ... Among 118 sarcomatoid RCC patients and 92 non-sarcomatoid clear cell renal cell carcinoma patients, Kawakami et al. The treatment plan was a combination of chemotherapy drugs, Ifosfamide and Adriamycin for 4 to 6 treatments. Study Identifies Three New Independent Prognostic ... The tumour consisted of typical clear cells of renal cell carcinoma and spindle cells compatible with malignant fibrous histiocytoma (MFH). An immunohistochemical study of 18 cases. Sarcomatoid renal cell carcinoma: an examination of underlying histologic subtype and an analysis of associations with patient outcome. The aim of this paper is to present a rare case of a 45-year-old male patient with SRCC. Fig. Sarcomatoid renal cell carcinoma | Urology News A high grade carcinoma of the kidney. Though there are multiple areas suspicious for sarcomatoid renal cell carcinoma, part C is most suspicious as this shows a more whitish, fleshy cut surface that appears to be different from the surrounding tumor. Sarcomatoid renal cell carcinoma is a form not to ignore despite its rarity. "Renal" means "kidney." "Carcinoma" is a word for cancers that begin in cells lining the internal organs. Renal cell carcinoma (RCC) with sarcomatoid differentiation belongs to the most aggressive clinicopathologic phenotypes of RCC. Sorafenib after combination therapy with gemcitabine plus doxorubicine in patients with sarcomatoid renal cell carcinoma: a prospective evaluation M Staehler and others European Journal of Medical Research, 2010. It is characterized by a high propensity for primary metastasis and limited therapeutic options due to its relative resistance to established systemic targeted therapy. The most common metastatic site was the lung (67%), followed by lymph nodes (LN) (62% . Both the patients were disease-free for first 2 years of follow-up; one patient . Sarcomatoid chromophobe renal cell carcinoma with heterologous sarcomatoid elements. Although an epithelial membrane antigen was demonstrated in the clear cells, this was not detected in the MFH-like spindle cells. A median survival time is only 4-9 months after diagnosis. In . Two patients had a smooth intraoperative course and the final biopsy revealed a clear-cell carcinoma with a sarcomatoid variant. Long-term survival is poor and the durable responses to systemic therapy are infrequent. Sarcomatoid chromophobe renal cell carcinoma with heterologous sarcomatoid elements. Sarcomatoid transformation is a microscopically identified feature of RCC accounting for 5% of all RCCs [2]. 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. Recent studies looking into the genomic and molecular characterization of sRCCs have provided … 141,142 Nevertheless, more tumors are being identified at a lower stage and these patients may have a . A, Axial unenhanced (A), axial contrast-enhanced (B), and coronal contrast-enhanced (C) CT images show large heterogeneous mass in upper pole of right kidney with invasion of lateral conal fascia (arrow, A and B) and renal sinus (solid arrow, C). 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. Sarcomatoid renal cell carcinomas (sRCC) may develop when one of the more common histologic subtypes of renal cell carcinoma degenerates into a sarcoma. Sarcomatoid renal cell carcinoma (sRCC) components are often large and can appear as dense grey or white areas within the tumour architecture and typically reveal a firm and fleshy cut surface . The incidence of renal cell carcinoma (RCC), the most frequent kidney tumor in adults, is progressively increasing worldwide [1, 2].Clear cell histology accounts for 75-85% of all RCC cases [].Sarcomatoid differentiation occurs in 10-15% of RCC and is associated with poor prognosis [].It has been shown that the epithelial to mesenchymal transition process orchestrates the sarcomatoid . It is Sarcomatoid Renal Cell Carcinoma. [ 1] If the results of contrast-enhanced computed tomography (CT) are indeterminate, use non-ionizing modalities, including magnetic resonance imaging (MRI) and contrast-enhanced . Keywords: Sarcomatoid renal cell carcinoma, Imaging features, Targeted therapies Background Sarcomatoid renal cell carcinoma (SRCC) is a form of dedifferentiated renal cell carcinoma (RCC) with aggres-sive behavior. Molina AM, Tickoo SK, Ishill N, et al. 2015 Oct 1;121(19):3435-43. Mainly symptomatic and discovered at an advanced stage, it has a poor prognosis, requiring multidisciplinary management quickly and correctly. Less common organs of metastasis include the brain, intestines, and bladder. Materials and methods: For this meta-analysis, we searched MEDLINE . Case Discussion. Volume 23, issue 7, pages 430-7. Phase 2 trial of sunitinib and gemcitabine in patients with sarcomatoid and/or poor-risk metastatic renal cell carcinoma. A sarcomatoid component can occur in all histologic subtypes of renal cell carcinoma (RCC) and indicates an aggressive tumor. Sarcomatoid Renal Cell Carcinoma listed as SRCC. On imaging, they are generally large masses, with irregular contours, and malignant-appearing, but do not have specific imaging features. 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). Cancer 12, 251-255 (2014).
