The SWI/SNF chromatin-remodeling complex status in renal cell carcinomas with sarcomatoid or rhabdoid features.

Virchows Arch 2020 May 23. Epub 2020 May 23.

Department of Anatomic Pathology, Graduate School of Medical Sciences, Kyushu University, Maidashi 3-1-1, Higashi-ku, Fukuoka, 812-8582, Japan.

The presence of sarcomatoid or rhabdoid features (which are associated with advanced disease and poor prognosis) is rarely observed in the subtypes of renal cell carcinoma (RCC). The SWI/SNF chromatin-remodeling complex, which is composed of evolutionarily conserved core subunits including SMARCB1/INI1 (SMARCB1), SMARCA4/BRG1 (SMARCA4), SMARCC1/BAF155 (SMARCC1), and SMARCC2/BAF170 (SMARCC2), can be regarded as the prototype of an epigenetic regulator of gene expression that is involved in tumor suppression. We analyzed the histological, immunohistochemical, and clinicopathological status in 72 cases of RCC with sarcomatoid or rhabdoid features, focusing on the expression status of the subunits of SWI/SNF chromatin-remodeling complex proteins.

Grading of renal cell carcinoma.

Histopathology 2019 Jan;74(1):4-17

Aquesta Uropathology, Brisbane, Qld, Australia.

Grading of renal cell carcinoma (RCC) has been recognised as a prognostic factor for almost 100 years. Numerous grading systems have been proposed, initially focusing upon a constellation of cytological features and more recently on nuclear morphology. It has been recommended that grading of RCC should be based upon nucleolar prominence/eosinophilia for grades 1-3, while grade 4 requires nuclear anaplasia (including tumour giant cells, sarcomatoid differentiation and/or rhabdoid morphology).

Renal medullary carcinoma (RMC) is a highly aggressive renal cell carcinoma arising in the collecting system and requiring careful correlation with status of sickle cell trait. A panel of international experts has recently proposed provisional diagnostic terminology, renal cell carcinoma, unclassified, with medullary phenotype, based on encountering an extraordinarily rare tumor with RMC morphology and immunophenotype in an individual proven not to have a hemoglobinopathy. Herein, we extend this observation to a cohort of 5 such tumors, morphologically similar to RMC, lacking SMARCB1 expression by immunohistochemistry, but each without evidence of a hemoglobinopathy.

Institut für Pathologie und Molekularpathologie, UniversitätsSpital Zürich, Schmelzbergstrasse 12, 8091, Zürich, Schweiz.

Histological tumor grading is an accepted prognostic parameter of renal cell carcinoma (RCC). In 2012, the International Society of Urologic Pathologists (ISUP) proposed a novel grading system for RCC, mainly based on the evaluation of nucleoli: grade 1 tumors have nucleoli that are inconspicuous and basophilic at ×400 magnification; grade 2 tumors have nucleoli that are clearly visible at ×400 magnification and eosinophilic; grade 3 tumors have clearly visible nucleoli at ×100 magnification; and grade 4 tumors have extreme pleomorphism or rhabdoid and/or sarcomatoid morphology. This grading system was validated for clear cell renal cell carcinoma and papillary renal cell carcinoma. Read More

Renal Neoplasms With Overlapping Features of Clear Cell Renal Cell Carcinoma and Clear Cell Papillary Renal Cell Carcinoma: A Clinicopathologic Study of 37 Cases From a Single Institution.

Am J Surg Pathol 2016 Feb;40(2):141-54

Robert J Tomsich Pathology and Laboratory Medicine Institute, Cleveland Clinic, Cleveland, OH.

Clear cell papillary renal cell carcinoma (CCPRCC) was recently included in the International Society of Urological Pathology Vancouver Classification of Renal Neoplasia as a subtype of RCC that is morphologically, immunohistochemically, and genetically distinct from both clear cell renal cell carcinoma (CCRCC) and papillary renal cell carcinoma. In our clinical practice we have observed tumors with overlapping histologic features of CCPRCC and CCRCC; therefore, our aim was to describe the morphologic, immunohistochemical, and clinical characteristics of these tumors. We examined a large series of consecutive nephrectomies diagnosed as CCRCC and found 37 tumors with morphologic overlap between CCRCC and CCPRCC, identifying 2 patterns. Read More

Gleason and Fuhrman no longer make the grade.

Histopathology 2016 Mar 16;68(4):475-81. Epub 2015 Nov 16.

Department of Pathology and Molecular Medicine, McMaster University, Hamilton, Ontario, Canada.

Grading is an important prognostic parameter for prostate adenocarcinoma and renal cell carcinoma (RCC); however, the most frequently used classifications fail to account for advances in our understanding of the diagnostic features, classification and/or behaviour of these tumours. In 2005 and 2014, the International Society of Urological Pathology (ISUP) proposed changes to Gleason scoring with the adoption of the ISUP grading for prostate cancer in 2014 (grade 1, score 3 + 3; grade 2, score 3 + 4; grade 3, score 4 + 3; grade 4, score 8; grade 5, score 9-10). Internationally the Fuhrman grading system is widely employed despite criticisms related to its application, validity, and reproducibility. Read More

Rhabdoid morphology in renal cell carcinoma (RCC) may, like sarcomatoid change, be perceived as a type of dedifferentiation, and is a poor prognostic factor. Histologically, rhabdoid neoplastic cells are round to polygonal cells with globular eosinophilic cytoplasmic inclusions and eccentric vesicular nuclei and enlarged nucleoli. All types of RCC, including clear cell, papillary, chromophobe, collecting duct carcinoma, renal medullary carcinoma, acquired cystic disease-associated RCC, ALK-positive renal cancer and unclassified RCC, may display a variably prominent rhabdoid phenotype.

Outcome prediction for patients with renal cell carcinoma.

Semin Diagn Pathol 2015 Mar 7;32(2):172-83. Epub 2015 Feb 7.

Department of Laboratory Medicine and Pathology, Mayo Clinic, 200 First St, Southwest Rochester, Minnesota 55905. Electronic address:

Outcome assessment for renal cell carcinoma is somewhat controversial. Despite numerous studies, a very limited variety of features have been recognized as having prognostic significance in clinical practice. In this review, tumor features considered to be of importance in outcome prediction for surgically treated patients with the 3 most commonly encountered morphotypes of renal cell carcinoma (clear cell, papillary, and chromophobe renal cell carcinoma) are evaluated.

Adult renal cell carcinoma with rhabdoid differentiation: incidence and clinicopathologic features in Chinese patients.

Ann Diagn Pathol 2015 Apr 2;19(2):57-63. Epub 2015 Feb 2.

Department of Urology, Peking University First Hospital, Institute of Urology, Peking University, Beijing, China.

Renal cell carcinoma (RCC) with rhabdoid differentiation is a recently described variant of RCC, which has seldom been reported in China. This form of differentiation has been generally associated with a poor prognosis and is often present in tumors with a poorly differentiated morphology. The development of a rhabdoid morphology appears to represent a common dedifferentiation pathway for renal parenchymal malignancies. Read More

Impact of Rhabdoid Differentiation on Prognosis for Patients with Grade 4 Renal Cell Carcinoma.

Eur Urol 2015 Jul 28;68(1):5-7. Epub 2015 Jan 28.

Department of Oncology, Mayo Clinic, Rochester, MN, USA. Electronic address:

Renal cell carcinoma (RCC) with rhabdoid differentiation is thought to portend a poor prognosis, similar to RCC with sarcomatoid differentiation. Both features are currently classified as grade 4 RCC based on the most recent International Society of Urological Pathology (ISUP) grading system. We reviewed a large series of patients with grade 4 RCC to determine the differential effects of rhabdoid and sarcomatoid differentiation on patient outcome. Read More

[Vancouver classification of renal tumors: Recommendations of the 2012 consensus conference of the International Society of Urological Pathology (ISUP)].

Pathologe 2015 May;36(3):310-6

Institut für Pathologie, Universitätsklinikum Bonn, Sigmund-Freud-Str. 25, 53127, Bonn, Deutschland,

The 2012 consensus conference of the International Society of Urological Pathology (ISUP) has formulated recommendations on classification, prognostic factors and staging as well as immunohistochemistry and molecular pathology of renal tumors. Agreement was reached on the recognition of five new tumor entities: tubulocystic renal cell carcinoma (RCC), acquired cystic kidney disease-associated RCC, clear cell (tubulo) papillary RCC, microphthalmia transcription factor family RCC, in particular t(6;11) RCC and hereditary leiomyomatosis-associated RCC. In addition three rare forms of carcinoma were considered as emerging or provisional entities: thyroid-like follicular RCC, succinate dehydrogenase B deficiency-associated RCC and anaplastic lymphoma kinase (ALK) translocation RCC.

Renal cell carcinoma with rhabdoid and sarcomatoid features presented as a metastatic thigh mass with an unusual immunohistochemical profile.

Rare Tumors 2014 Jan 18;6(1):5037. Epub 2014 Mar 18.

Department of Pathology, Faculty of Medicine, Menofiya University , Shebein Elkom, Egypt.

Renal cell carcinoma (RCC) may metastasize anywhere in the body and sometimes the primary tumor is missing and necessitates extensive investigations to detect. In this report, we describe a case of RCC metastasizing to the thigh in a 70 year old male with a highly pleomorphic morphology suggesting a high grade sarcoma that showed unequivocal positivity for desmin directing the diagnosis for pleomorphic rhabdomyosarcoma. After completion of 33 cycles of radiotherapy, the patient developed large intraabdominal mass that showed conventional areas of RCC with immunoreactivity for CD10, CK, EMA, carbonic anhydrase IX and vimentin.

Hereditary leiomyomatosis and renal cell carcinoma (HLRCC): a rapid autopsy report of metastatic renal cell carcinoma.

Am J Surg Pathol 2014 Apr;38(4):567-77

Departments of *Pathology #Urology †Internal Medicine, Division of Hematology and Oncology ‡Comprehensive Cancer Center, University of Michigan Health System ∥Michigan Center for Translational Pathology ¶Howard Hughes Medical Institute, Ann Arbor, MI §Department of Pathology, Memorial Sloan-Kettering Cancer Center, New York, NY.

Rapid ("warm") autopsies of patients with advanced metastatic cancer provide invaluable insight into the natural history, pathobiology, and morphology of advanced and treatment-resistant tumors. Here, we report a rapid autopsy case of a hereditary leiomyomatosis and renal cell carcinoma (HLRCC) patient with advanced metastatic renal cell carcinoma (RCC)-the first such case described for either a primary renal tumor or HLRCC-related cancer. Mutations in the fumarate hydratase (FH) gene underlie HLRCC, a rare syndrome involving cutaneous and uterine leiomyomata and aggressive kidney tumors. Read More

The International Society of Urological Pathology 2012 Consensus Conference made recommendations regarding classification, prognostic factors, staging, and immunohistochemical and molecular assessment of adult renal tumors. Issues relating to prognostic factors were coordinated by a workgroup who identified tumor morphotype, sarcomatoid/rhabdoid differentiation, tumor necrosis, grading, and microvascular invasion as potential prognostic parameters. There was consensus that the main morphotypes of renal cell carcinoma (RCC) were of prognostic significance, that subtyping of papillary RCC (types 1 and 2) provided additional prognostic information, and that clear cell tubulopapillary RCC was associated with a more favorable outcome.

A novel grading system for clear cell renal cell carcinoma incorporating tumor necrosis.

Am J Surg Pathol 2013 Mar;37(3):311-22

Department of Pathology and Molecular Medicine, Wellington School of Medicine and Health Sciences, University of Otago, Wellington, New Zealand.

Grading of renal cell carcinoma (RCC) has prognostic significance, and there is recent consensus by the International Society of Urological Pathology (ISUP) that for clear cell and papillary RCC, grading should primarily be based on nucleolar prominence. Microscopic tumor necrosis also predicts outcome independent of tumor grading. This study was undertaken to assess whether the incorporation of microscopic tumor necrosis into the ISUP grading system provides survival information superior to ISUP grading alone. Read More

Identification of anaplastic lymphoma kinase fusions in renal cancer: large-scale immunohistochemical screening by the intercalated antibody-enhanced polymer method.

Cancer 2012 Sep 17;118(18):4427-36. Epub 2012 Jan 17.

Japanese Foundation for Cancer Research, Tokyo, Japan.

Background: Several promising molecular-targeted drugs are used for advanced renal cancers. However, complete remission is rarely achieved, because none of the drugs targets a key molecule that is specific to the cancer, or is associated with "oncogene addiction" (dependence on one or a few oncogenes for cell survival) of renal cancer. Recently, an anaplastic lymphoma kinase (ALK) fusion, vinculin-ALK, has been reported in pediatric renal cell carcinoma (RCC) cases who have a history of sickle cell trait. Read More

Adult renal cell carcinoma with rhabdoid morphology represents a neoplastic dedifferentiation analogous to sarcomatoid carcinoma.

Ann Diagn Pathol 2011 Oct 12;15(5):333-7. Epub 2011 Jun 12.

Department of Pathology, University of Miami Miller School of Medicine, Sylvester Comprehensive Cancer Center, FL 33138, USA.

Renal cell carcinoma (RCC) with rhabdoid morphology (RCC-RM) is a recently described variant of RCC, which has an aggressive biologic behavior and poor prognosis, akin to sarcomatoid RCC. The current World Health Organization classification of RCC does not include the rhabdoid phenotype as a distinct histologic entity. The aim of this study is to investigate whether RCC-RM represents a dedifferentiation of a classifiable-type World Health Organization RCC or a carcinosarcoma with muscle differentiation. Read More
