Introduction: Renal cell carcinoma (RCC) involves serosal surfaces in 2%-3% of cases, and thus few papers describe serous fluid cytology (SFC) involvement by RCC. This diagnosis is challenging, given its rarity, nondescript cytomorphologic features and infrequent expression of widely used epithelial markers MOC31 and BerEP4. We describe our institutional experience with RCC in SFC specimens.

To predict the therapeutic response of systemic therapy, comprehensive analyses of the tumor microenvironment in papillary renal cell carcinoma (pRCC) have been conducted previously using immunohistochemistry and RNA sequencing. This study aimed to evaluate the correlation between hematoxylin and eosin-based histological immunophenotypes and gene signatures employed in several clinical trials predicting responsiveness to immune checkpoint inhibitors and tyrosine kinase inhibitors, using data from the Cancer Genome Atlas (TCGA)-KIRP cohort (n = 254). Herein, we evaluated tumor-associated immune cells (TAICs) using three methodologies previously reported in clear cell RCC: a 3-tier immunophenotype (desert, excluded, and inflamed) based on the spatial distribution of TAICs; a 4-tier immunophenotype (cold, immune-low, excluded, and hot) considering both the location and degree of TAICs; and an inflammation score (score 0, 1, and 2) focusing only on the degree of TAICs.

Article Synopsis
  • Renal cell carcinoma (RCC) with sarcomatoid and rhabdoid features exhibits aggressive behavior and poor prognosis, yet is not classified as a separate type in the 2022 WHO classification.
  • Sarcomatoid RCC is characterized by malignant spindle cells, while rhabdoid cells display distinct eccentric nuclei and large inclusions, both showing unique molecular features that indicate a clonal evolution.
  • New immunotherapy treatments targeting PD-1/PD-L1/CTLA-4 have shown promise, highlighting the importance of recognizing these specific tumor features for better management and treatment outcomes.

[2022 WHO classification of renal cell carcinomas: Focus on papillary renal cell carcinoma].

Ann Pathol

September 2024

Service d'anatomie et cytologie pathologiques, CHU de Rennes-Hôpital Pontchaillou, 2, rue Henri-Le-Guilloux, 35033 Rennes cedex 9, France. Electronic address:

Renal cell carcinomas (RCC) represent a group of heterogeneous tumors whose classification has greatly evolved since 1981. The latest update in 2022 classifies all renal cell carcinomas into six categories according to their morphology or the detection of specific molecular alterations. Molecular disassembly of renal cell carcinomas with papillary features has enabled the identification of new entities characterized by a specific molecular alteration, such as Fumarate Hydratase (FH) deficient RCC, TFE3-rearranged RCC or TFEB-altered RCC.

Article Synopsis
  • - This multi-institutional study aimed to investigate the prognostic impact of histomorphological subtyping in patients with nonmetastatic papillary renal cell carcinoma (papRCC) who underwent curative surgery, involving 1,086 patients categorized into two subtypes.
  • - Results showed that patients with type 2 papRCC were generally older, had larger tumors, and exhibited poorer survival rates, with lower 5-year recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) than type 1 patients.
  • - While type 2 was a significant predictor for RFS and CSS, it had no significant impact on OS, highlighting the need for further understanding of how these

  • Succinate dehydrogenase (SDH)-deficient renal cell carcinoma (RCC) is a rare tumor with lower-grade characteristics but can exhibit aggressive features, as shown in a case of a 36-year-old woman who presented with severe symptoms and advanced disease.
  • The patient's tumor displayed a mix of low-grade and high-grade features, including significant rhabdoid and sarcomatoid differentiation, leading to a poor prognosis despite the generally favorable outlook of SDH-deficient RCC.
  • This case underscores the complexities of diagnosing high-grade tumors in SDH-deficient RCC and highlights the need for genetic testing and ongoing surveillance for related neoplasms due to the increased risk of metastasis.

  • The study aimed to identify predictors of aggressive pathology in cT1 solid renal cell carcinoma (RCC) by integrating clinical features and CT scan data to create a nomogram model.
  • In a retrospective analysis of 776 RCC patients, key factors such as neutrophil-to-lymphocyte ratio, tumor characteristics, and CT findings were found to significantly predict aggressive pathology, with 32.2% of patients exhibiting such features.
  • The nomogram developed from these predictors showed strong accuracy, with an area under the curve of 0.854, suggesting its potential utility in clinical decision-making for RCC treatment.

In this review, we highlight and contextualize emerging morphologic prognostic and predictive factors in renal cell carcinoma. We focus on clear cell renal cell carcinoma (ccRCC), the most common histologic subtype. Our understanding of the molecular characterization of ccRCC has dramatically improved in the last decade.

Article Synopsis
  • Metastatic renal cell carcinoma (RCC) with sarcomatoid and/or rhabdoid dedifferentiation shows aggressive behavior but responds better to immune checkpoint therapy (ICT), although outcomes with VEGFR-targeted therapies after ICT progression were previously unclear.

Article Synopsis
  • SETD2 and BAP1 are chromatin remodeling genes that are frequently mutated in clear cell renal cell carcinoma (ccRCC) and play a role in tumor progression and metastasis.
  • A study compared 7 cases of locally advanced ccRCC with SETD2 mutations to 7 cases with BAP1 mutations, finding that SETD2-mutated tumors exhibited aggressive growth with a rhabdoid morphology and significant invasive characteristics.
  • The study emphasizes the importance of molecular testing for SETD2 and BAP1 mutations in ccRCC for better risk assessment and treatment strategies, as their high-grade features can overlap, making it challenging to identify the mutations based solely on tumor appearance.

Article Synopsis
  • - Clear cell renal cell carcinoma (RCC) is the most prevalent type of kidney cancer, making up 60%-70% of adult cases, and is strongly linked to mutations in the von Hippel-Lindau gene on chromosome 3p, found in over 90% of cases.
  • - Other tumor suppressor genes on chromosome 3p also play a role in the development of these tumors, with specific mutations leading to unique histopathological characteristics.
  • - The report details two cases of clear cell RCC with distinct mutations, highlighting aggressive features, including high-grade nuclei, eosinophilic granules, and the presence of rhabdoid and sarcomatoid cells, indicating a severe clinical outcome.

  • The study aims to analyze the surgical treatment, perioperative outcomes, and the impact of aggressive histologic variants (AHV) in patients with renal cell carcinoma (RCC) and inferior vena cava (IVC) thrombus, noting that AHV indicates a poorer prognosis.* -
  • Researchers reviewed data from 403 patients who underwent surgery from 1990 to 2020, finding that 23.3% had AHV and were more likely to show advanced disease stages, but surgery did not lead to worse perioperative outcomes.* -
  • Results indicated that while the median survival was similar for patients with and without AHV, sarcomatoid differentiation significantly worsened overall survival, highlighting the need for careful evaluation in surgical

  • The study examined the role of XB130 expression in three types of renal cell carcinoma (RCC) and its impact on patient outcomes using 101 nephrectomy samples from a Thai hospital.
  • Results indicated that high XB130 levels in clear cell and papillary RCC were linked to poorer prognosis and several adverse clinical features, including higher tumor grades and the presence of metastasis.
  • The findings suggest that XB130 expression serves as an independent risk factor for mortality, highlighting its potential as a prognostic marker in RCC patients.
