METHODS: French patients (≤18years) treated for dysgerminoma between 1985 and 2005 in TGM-85, 90, 95 protocols were included. Treatment was based on primary unilateral oophorectomy followed by prophylactic lymph node irradiation (1985-1998) or a wait-and-see strategy (1998-2005) for localised completely resected tumours (pS1) or by platinum-based chemotherapy for advanced diseases. RESULTS: Forty-eight patients (median age 12.8 years) were included. Six patients had gonadal dysgenesis...

Renal angiomyolipoma (AML) is an uncommon renal tumour, generally composed of mature adipose tissue, dysmorphic blood vessels, and smooth muscle. Identification of intratumoural fat on unenhanced CT images (UECT) is the most reliable finding for establishing the diagnosis of renal AML. However, AMLs sometimes exhibit atypical findings, including cystic as well as solid forms; some of these variants overlap with the appearance of other renal tumours. A rare type of AML, the epithelioid type, possesses malignant potential...

Renal cell carcinomas (RCCs) with t(6,11) are very rare tumours. Only a few cases have been reported so far. t(6,11) results in fusion of alpha gene and transcription factor EB (TFEB) gene resulting in the overexpression of TFEB. The specific light and immunohistochemical features help in the diagnosis of this rare type of tumor. We report a case of t(6,11) RCC in a 38-year-old female who was incidentally found to have a right renal mass. We present this case to emphasize the typical light microscopic picture of this extremely rare tumor...

Hypoxia promotes tumour aggressiveness and reduces patient survival. A spectrum of poor outcome among patients with hypoxic tumours suggests that additional factors modulate how tumours respond to hypoxia. PIWI-interacting RNAs (piRNAs) are small non-coding RNAs with a pivotal role in genomic stability and epigenetic regulation of gene expression. We reported that cancer type-specific piRNA signatures vary among patients. However, remarkably homogenous piRNA profiles are detected across patients with renal cell carcinoma, a cancer characterized by constitutive upregulation of hypoxia-related signaling induced by common mutation or loss of von Hippel-Lindau factor (VHL)...

Clear cell renal cell carcinoma (ccRCC) is an heterogeneous tumour at architectural, cellular and molecular level, a reason why the 2014 International Society of Urological Pathology consensus recommended wide sampling of RCC masses to include at least 1 block/cm of tumour together with perpendicular sections of the tumour/perinephric fat interface and the tumour/renal sinus interface. Intratumoural molecular heterogeneity may be a limitation at the moment of defining precision medicine strategies based on gene mutation status...

AIM: To investigate if the early treatment effects of radiofrequency ablation (RFA) on renal cell carcinoma (RCC) can be detected with dynamic contrast enhanced (DCE)-MRI and to correlate RCC perfusion with RFA treatment time. MATERIALS AND METHODS: 20 patients undergoing RFA of their 21 RCCs were evaluated with DCE-MRI before and at one month after RFA treatment. Perfusion was estimated using the maximum slope technique at two independent sittings. Total RCC blood flow was correlated with total RFA treatment time, tumour location, size and histology...

OBJECTIVES: To assess the efficacy of irreversible electroporation (IRE) ablation of pT1a renal-cell carcinoma (RCC) in the first prospective, monocentric Phase 2a pilot ablate-and-resect study (IRENE trial). It has been postulated that focal IRE can bring about complete ablation of soft-tissue tumours with protection of healthy peritumoral tissue and anatomical structures. METHODS: The first seven study patients, with biopsy-proven pT1a RCC (15-39mm) underwent IRE...

Purpose: Clear cell Renal Cell Carcinomas (ccRCC), the largest group of renal tumours, are resistant to classical therapies. The determination of the functional state of actionable biomarkers for the assessment of these adenocarcinomas is essential. The dysregulation of the oncoprotein, PKB/Akt has been linked with poor prognoses in human cancers. Material & methods: We analysed the status of the PKB/Akt pathway in a representative tumour tissue microarray obtained from the primary tumours and their metastases in 60 ccRCC with long term follow up...

Renal angiomyolipoma (AML) are benign tumours composed of fat, muscle, and disorganised blood vessels. Historic treatment algorithms for sporadic AML based on size fail to consider additional risk factors such as tumour vascularity and pseudoaneurysm formation. As AML is now predominantly incidental, rupture is rare and its mortality low. The recent publication of the largest longitudinal series to date also suggest that growth is uncommon, challenging existing surveillance paradigms. The evidence assessing treatment strategies in AML are reviewed, with particular emphasis on incidental sporadic AML...

Carbonic anhydrase (CA, EC 4.2.1.1) IX is regarded as a tumour hypoxia marker and CA inhibitors have been proposed as a new class of antitumor agents, with one such agent in Phase II clinical trials. The expression of some CAs, in particular the isoforms CA IX and CA XII, has been correlated with tumour aggressiveness and progression in several cancers. The aim of this study was to evaluate the possibility that CA IX could represent a marker related to clear cell Renal Cell Carcinoma (ccRCC). Bcl-2 and Bax, and the activity of caspase-3, evaluated in tissue biopsies from patients, were congruent with resistance to apoptosis in ccRCCs with respect to healthy controls, respectively...

The oncogenic mechanisms and tumour biology underpinning Clear Cell Sarcoma of Kidney (CCSK), the second commonest paediatric renal malignancy, are poorly understood and currently therapy depends heavily on doxorubicin with cardiotoxic side-effects. Previously, we characterised the balanced t(10;17)(q22;p13) chromosomal translocation, identified at that time as the only recurrent genetic aberration in CCSK. This translocation results in an in-frame fusion of the genes YWHAE (encoding 14-3-3ε)and NUTM2, with a somatic incidence of 12%...

Precision therapy for clear cell renal cell carcinoma (ccRCC) requires molecular biomarkers ascertaining disease prognosis. In this study, we performed integrated proteomic and transcriptomic screening in all four tumour-node-metastasis stages of ccRCC and adjacent normal tissues (n = 18) to investigate differentially expressed genes. Most identified differentially expressed genes revealed a strong association with transforming growth factor-β level and the epithelial-to-mesenchymal transition process. Of them, Serpin peptidase inhibitor clade H member 1 (SERPINH1) revealed the strongest association with poor prognosis and regulation on the expression levels of epithelial-to-mesenchymal transition markers...

The worldwide incidence of thyroid malignancies has been increasing rapidly. Sensitive imaging modalities and early detection of thyroid lesions have made thyroid cancers the most rapidly increasing cancers in the USA in 2017 (SEER Cancer Facts, 2017). Clinical awareness of potential risk factors, such as inherited thyroid cancers, has allowed earlier recognition of more vulnerable population clusters. Hereditary thyroid neoplasms arising from calcitonin-producing C cells are known as familial medullary thyroid carcinomas (FMTCs), and include well-documented syndromes such as multiple endocrine neoplasia IIA or IIB, and pure familial medullary thyroid carcinoma syndrome...

#18
REVIEW
Anthony J Gill
The succinate dehydrogenase (SDH) complex is a key respiratory enzyme composed of four subunits: SDHA, SDHB, SDHC and SDHD. Remarkably, immunohistochemistry for SDHB becomes negative whenever there is bi-alleic inactivation of any component of SDH, which is very rare in the absence of syndromic disease. Therefore, loss of SDHB immunohistochemistry serves as a marker of syndromic disease, usually germline mutation of one of the SDH subunits. Tumours which show loss of SDHB expression are termed succinate dehydrogenase-deficient...
