  1. Fulltext Endobronchial metastasis from resected renal cell carcinoma causing total lung collapse
    Poh ME, Liam CK, Pang YK, Chua KT
    Respirol Case Rep, 2013 Dec;1(2):26-7.
    PMID: 25473534 DOI: 10.1002/rcr2.16
    We report a man presenting with dyspnea, cough, and hemoptysis due to left lung collapse from an endobronchial tumor obstructing the left main bronchus. Endobronchial biopsy of the tumor showed renal cell carcinoma, identical to a previous specimen of renal cell carcinoma removed by a radical left nephrectomy five years ago. The endobronchial tumor was removed by snare diathermy through a flexible bronchoscope, following which his symptoms resolved and the left lung re-expanded. Endobronchial metastasis from renal cell carcinoma is rare and can mimic obstruction from other endobronchial etiologies, such as bronchogenic carcinoma. Total lung collapse as a result is even more uncommon, although atelectasis is well described. Endobronchial techniques, such as snare diathermy, can relieve obstruction, providing symptom palliation even in advanced disease.

  2. Fulltext Endogenous HIF2A reporter systems for high-throughput functional screening
    Zaini MN, Patel SA, Syafruddin SE, Rodrigues P, Vanharanta S
    Sci Rep, 2018 08 13;8(1):12063.

    Tissue-specific transcriptional programs control most biological phenotypes, including disease states such as cancer. However, the molecular details underlying transcriptional specificity is largely unknown, hindering the development of therapeutic approaches. Here, we describe novel experimental reporter systems that allow interrogation of the endogenous expression of HIF2A, a critical driver of renal oncogenesis. Using a focused CRISPR-Cas9 library targeting chromatin regulators, we provide evidence that these reporter systems are compatible with high-throughput screening. Our data also suggests redundancy in the control of cancer type-specific transcriptional traits. Reporter systems such as those described here could facilitate large-scale mechanistic dissection of transcriptional programmes underlying cancer phenotypes, thus paving the way for novel therapeutic approaches.

  3. Establishment of epithelial and fibroblast cell cultures and cell lines from primary renal cancer nephrectomies
    Yap NY, Ong TA, Morais C, Pailoor J, Gobe GC, Rajandram R
    Cell Biol Int, 2019 Jun;43(6):715-725.
    PMID: 31062478 DOI: 10.1002/cbin.11150
    Renal cell carcinoma (RCC) is one of the most lethal urogenital cancers and effective treatment of metastatic RCC remains an elusive target. Cell lines enable the in vitro investigation of molecular and genetic changes leading to renal carcinogenesis and are important for evaluating cellular drug response or toxicity. This study details a fast and easy protocol of establishing epithelial and fibroblast cell cultures or cell lines concurrently from renal cancer nephrectomy tissue. The protocol involves mechanical disaggregation, collagenase digestion and cell sieving for establishing epithelial cells while fibroblast cells were grown from explants. This protocol has been modified from previous published reports with additional antibiotics and washing steps added to eliminate microbial contamination from the surgical source. Cell characterisation was carried out using immunofluorescence and quantitative polymerase chain reaction. Eleven stable epithelial renal tumour cell lines of various subtypes, including rare subtypes, were established with a spontaneous immortalisation rate of 21.6% using this protocol. Eight fibroblast cell cultures grew successfully but did not achieve spontaneous immortalisation. Cells of epithelial origin expressed higher expressions of epithelial markers such as pan-cytokeratin, cytokeratin 8 and E-cadherin whereas fibroblast cells expressed high α-smooth muscle actin. Further mutational analysis is needed to evaluate the genetic or molecular characteristics of the cell lines.

  4. Fulltext Expression of protease activated receptor-2 is reduced in renal cell carcinoma biopsies and cell lines
    Morais C, Rajandram R, Blakeney JS, Iyer A, Suen JY, Johnson DW, et al.
    PLoS One, 2021;16(3):e0248983.
    PMID: 33765016 DOI: 10.1371/journal.pone.0248983
    Expression of the protease sensing receptor, protease activated receptor-2 (PAR2), is elevated in a variety of cancers and has been promoted as a potential therapeutic target. With the development of potent antagonists for this receptor, we hypothesised that they could be used to treat renal cell carcinoma (RCC). The expression of PAR2 was, therefore, examined in human RCC tissues and selected RCC cell lines. Histologically confirmed cases of RCC, together with paired non-involved kidney tissue, were used to produce a tissue microarray (TMA) and to extract total tissue RNA. Immunohistochemistry and qPCR were then used to assess PAR2 expression. In culture, RCC cell lines versus primary human kidney tubular epithelial cells (HTEC) were used to assess PAR2 expression by qPCR, immunocytochemistry and an intracellular calcium mobilization assay. The TMA revealed an 85% decrease in PAR2 expression in tumour tissue compared with normal kidney tissue. Likewise, qPCR showed a striking reduction in PAR2 mRNA in RCC compared with normal kidney. All RCC cell lines showed lower levels of PAR2 expression than HTEC. In conclusion, we found that PAR2 was reduced in RCC compared with normal kidney and is unlikely to be a target of interest in the treatment of this type of cancer.

    MyJurnal
    Fine needle aspiration cytology under radiologic guidance for diagnosis of renal cell carcinoma is well established and is increasingly utilized. This is because renal cell carcinoma displays fairly characteristic cellular features permitting correct cytologic identification. We present a case of a 66-year-old man who had advanced renal cell carcinoma with spread to aortic and cervical lymph nodes, lungs and liver. Fine needle aspiration cytology of the para-aortic mass showed tight clusters of malignant cells with abundant and vacuolated cytoplasm consistent with renal cell carcinoma. Histology of the left cervical lymph nodes together with immunohistochemistry findings were consistent with the cytologic diagnosis of metastatic renal cell carcinoma. The patient succumb to his illness three years after the diagnosis was made.

  7. Fulltext Genetic Variants Related to Longer Telomere Length are Associated with Increased Risk of Renal Cell Carcinoma
    Machiela MJ, Hofmann JN, Carreras-Torres R, Brown KM, Johansson M, Wang Z, et al.
    Eur Urol, 2017 Nov;72(5):747-754.
    PMID: 28797570 DOI: 10.1016/j.eururo.2017.07.015
    BACKGROUND: Relative telomere length in peripheral blood leukocytes has been evaluated as a potential biomarker for renal cell carcinoma (RCC) risk in several studies, with conflicting findings.

    OBJECTIVE: We performed an analysis of genetic variants associated with leukocyte telomere length to assess the relationship between telomere length and RCC risk using Mendelian randomization, an approach unaffected by biases from temporal variability and reverse causation that might have affected earlier investigations.

    DESIGN, SETTING, AND PARTICIPANTS: Genotypes from nine telomere length-associated variants for 10 784 cases and 20 406 cancer-free controls from six genome-wide association studies (GWAS) of RCC were aggregated into a weighted genetic risk score (GRS) predictive of leukocyte telomere length.

    OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Odds ratios (ORs) relating the GRS and RCC risk were computed in individual GWAS datasets and combined by meta-analysis.

    RESULTS AND LIMITATIONS: Longer genetically inferred telomere length was associated with an increased risk of RCC (OR=2.07 per predicted kilobase increase, 95% confidence interval [CI]:=1.70-2.53, p<0.0001). As a sensitivity analysis, we excluded two telomere length variants in linkage disequilibrium (R2>0.5) with GWAS-identified RCC risk variants (rs10936599 and rs9420907) from the telomere length GRS; despite this exclusion, a statistically significant association between the GRS and RCC risk persisted (OR=1.73, 95% CI=1.36-2.21, p<0.0001). Exploratory analyses for individual histologic subtypes suggested comparable associations with the telomere length GRS for clear cell (N=5573, OR=1.93, 95% CI=1.50-2.49, p<0.0001), papillary (N=573, OR=1.96, 95% CI=1.01-3.81, p=0.046), and chromophobe RCC (N=203, OR=2.37, 95% CI=0.78-7.17, p=0.13).

    CONCLUSIONS: Our investigation adds to the growing body of evidence indicating some aspect of longer telomere length is important for RCC risk.

    PATIENT SUMMARY: Telomeres are segments of DNA at chromosome ends that maintain chromosomal stability. Our study investigated the relationship between genetic variants associated with telomere length and renal cell carcinoma risk. We found evidence suggesting individuals with inherited predisposition to longer telomere length are at increased risk of developing renal cell carcinoma.

  8. High-risk human papillomavirus infection in different histological subtypes of renal cell carcinoma
    Farhadi A, Behzad-Behbahani A, Geramizadeh B, Sekawi Z, Rahsaz M, Sharifzadeh S
    J Med Virol, 2014 Jul;86(7):1134-44.
    PMID: 24700118 DOI: 10.1002/jmv.23945
    Limited data exist regarding whether a high-risk human papillomavirus (HR-HPV) infection increases the risk of developing renal cell carcinoma. The aim of this study was to investigate whether HPV infection has a role in the pathogenesis or development of a certain histological subtype of renal cell carcinoma. Formalin-fixed paraffin-embedded (FFPE) specimens of 122 patients with histopathologically proven renal cell carcinoma and their respective peritumoral tissues were examined. The presence of HPV-DNA was determined by a combination of MY/GP+ consensus primers and HPV-16/18 type specific nested PCRs followed by direct sequencing. Catalyzed signal-amplified colorimetric in situ hybridization (CSAC-ISH) technique was applied to determine the physical status of viral genome. The expression of p16INK4a and HPV L1 capsid proteins was evaluated using immunohistochemistry. HPV genome was detected in 37 (30.3%) tumor specimens and their four (4.1%) corresponding peritumoral tissues. HPV-18 was the most common viral type identified followed by HPV-16 and 58. Immunoexpression of p16INK4a was detected in 24 (20.3%) cases. Data analysis showed a significant correlation between p16INK4a expression and the presence of HR-HPV DNA (P renal cell carcinoma. It is proposed that HPV infection in high-grade tumors might precede disease progression in a number of tumors, particularly of the papillary subtype.

  9. Human renal carcinoma cells respond to Newcastle disease virus infection through activation of the p38 MAPK/NF-κB/IκBα pathway
    Ch'ng WC, Abd-Aziz N, Ong MH, Stanbridge EJ, Shafee N
    Cell Oncol (Dordr), 2015 Aug;38(4):279-88.
    PMID: 25930675 DOI: 10.1007/s13402-015-0229-5
    Newcastle disease virus (NDV) is an oncolytic virus that is known to have a higher preference to cancer cells than to normal cells. It has been proposed that this higher preference may be due to defects in the interferon (IFN) responses of cancer cells. The exact mechanism underlying this process, however, remains to be resolved. In the present study, we examined the antiviral response towards NDV infection of clear cell renal cell carcinoma (ccRCC) cells. ccRCC is associated with mutations of the von Hippel-Lindau tumor suppressor gene VHL, whose protein product is important for eliciting cellular responses to changes in oxygen levels. The most common first line treatment strategy of ccRCC includes IFN. Unfortunately, most ccRCC cases are diagnosed at a late stage and often are resistant to IFN-based therapies. Alternative treatment approaches, including virotherapy using oncolytic viruses, are currently being investigated. The present study was designed to investigate the mechanistic pathways underlying the response of ccRCC cells to oncolytic NDV infection.

  10. Fulltext KIM-1 as a Blood-Based Marker for Early Detection of Kidney Cancer: A Prospective Nested Case-Control Study
    Scelo G, Muller DC, Riboli E, Johansson M, Cross AJ, Vineis P, et al.
    Clin Cancer Res, 2018 Nov 15;24(22):5594-5601.
    PMID: 30037816 DOI: 10.1158/1078-0432.CCR-18-1496
    Purpose: Renal cell carcinoma (RCC) has the potential for cure with surgery when diagnosed at an early stage. Kidney injury molecule-1 (KIM-1) has been shown to be elevated in the plasma of RCC patients. We aimed to test whether plasma KIM-1 could represent a means of detecting RCC prior to clinical diagnosis.Experimental Design: KIM-1 concentrations were measured in prediagnostic plasma from 190 RCC cases and 190 controls nested within a population-based prospective cohort study. Cases had entered the cohort up to 5 years before diagnosis, and controls were matched on cases for date of birth, date at blood donation, sex, and country. We applied conditional logistic regression and flexible parametric survival models to evaluate the association between plasma KIM-1 concentrations and RCC risk and survival.Results: The incidence rate ratio (IRR) of RCC for a doubling in KIM-1 concentration was 1.71 [95% confidence interval (CI), 1.44-2.03, P = 4.1 × 10-23], corresponding to an IRR of 63.3 (95% CI, 16.2-246.9) comparing the 80th to the 20th percentiles of the KIM-1 distribution in this sample. Compared with a risk model including known risk factors of RCC (age, sex, country, body mass index, and tobacco smoking status), a risk model additionally including KIM-1 substantially improved discrimination between cases and controls (area under the receiver-operating characteristic curve of 0.8 compared with 0.7). High plasma KIM-1 concentrations were also associated with poorer survival (P = 0.0053).Conclusions: Plasma KIM-1 concentrations could predict RCC incidence up to 5 years prior to diagnosis and were associated with poorer survival.

  11. Leptin and its receptor: can they help to differentiate chromophobe renal cell carcinoma from renal oncocytoma?
    Ng KL, Del Vecchio SJ, Samaratunga H, Morais C, Rajandram R, Vesey DA, et al.
    Pathology, 2018 Aug;50(5):504-510.
    PMID: 29970253 DOI: 10.1016/j.pathol.2018.01.007
    One of the challenges in differentiating chromophobe renal cell carcinoma (chRCC) from benign renal oncocytoma (RO) is overlapping morphology between the two subtypes. The aim of this study was to investigate the usefulness of expression of leptin (Ob) and its receptor (ObR) in discriminating chRCC from RO. Sections from paraffin-embedded, formalin-fixed tumour nephrectomy specimens of 45 patients, made up of 30 chRCC (15 eosinophilic variant and 15 non-eosinophilic variant) and 15 RO, were used in this study. Samples (30) of clear cell RCC (ccRCC), the most common histological subtype, were used to verify staining patterns found by others in our cohort of Australasian patients. Matched morphologically normal non-cancer kidney tissues were included for each specimen. Sections were batch-immunostained using antibodies against Ob and ObR. Stained sections were digitally scanned using Aperio ImageScope, and the expression pattern of Ob and ObR was studied. In this cohort, male to female ratio was 2:1; median age was 64 (45-88 years); and median tumour size was 3.8 cm (range 1.2-18 cm). There were 47 (62.7%) T1, seven T2, 20 T3 and one T4 stage RCC. Two patients with ccRCC presented with metastases. Nuclear expression of Ob was significantly higher in RO compared with chRCC. The increased nuclear expression of Ob in RO compared with chRCC may be a useful aid in the difficult histological differentiation of RO from chRCC, especially eosinophilic variants of chRCC.

  12. Fulltext Management of renal cell carcinoma in von hippel-lindau syndrome: case report and review of literature
    Aroona, S., Shamsuddin, O.
    Journal of Surgical Academia, 2015;5(1):75-78.
    MyJurnal
    Renal cell carcinoma (RCC) is the one of the most common type of of cancer of the kidneys affecting adults. A 35- year-old man, with Von Hippel Lindau (VHL) syndrome was referred for bilateral renal mass in a follow up CT for evaluation. Open partial left nephrectomy was performed and the final histopathological report confirmed the diagnosis. One of the most important genetic and hereditary risk factor for RCC is Von Hippel-Lindau syndrome (VHL). RCC in VHL may occur bilaterally in some cases, so preserving renal parenchymal function is a major therapeutic goal and nephron sparing surgery provides a favorable patient outcome.

    Metastatic disease involving the thyroid gland is uncommon. Solitary thyroid metastases from various primary sites particularly kidney, lung, and breast had been previously described. To the best of our knowledge, metastases from two topographically separate primary malignancies to the thyroid have never been documented hitherto. This is the first reported case of cancer-to-cancer metastasis involving an invasive breast carcinoma metastasized within a metastatic renal cell carcinoma in the nonneoplastic thyroid in a 58-year-old woman. Distinguishing a secondary thyroid metastases from a primary thyroid malignancy is utmost crucial as treatment differs. The possibility of tumor metastases from two separated primaries should always be considered in a tumor exhibiting malignant cell populations with two distinctive histomorphological appearances. The role of immunohistochemistry stains in equivocal cases cannot be overemphasized.

    Cancer metastasis to the thyroid gland from non-thyroid sites is a rare presentation in clinical practice. The most frequent primary cancers that metastasise to the thyroid are renal cell carcinoma, followed by colorectal, lung and breast. We report a case of a 64-year-old Malay lady who presented with anterior neck swelling 4 years after an initial diagnosis of uterine leiomyosarcoma. She had undergone a hysterectomy procedure four years ago. Fine needle aspiration cytology of the thyroid mass suggested undifferentiated thyroid carcinoma. After multi-disciplinary discussion, the patient underwent thyroidectomy and the final histopathological diagnosis was metastatic leiomyosarcoma of the thyroid. The diagnosis was aided by an immunohistochemistry panel of positive myogenic markers, negative epithelial markers as well as the previous medical history of uterine leiomyosarcoma. Metastatic leiomyosarcoma of the thyroid may mimic primary undifferentiated (anaplastic) thyroid carcinoma (UTC) with a sarcomatoid pattern, medullary thyroid carcinoma (MTC) with spindle cells morphology and spindle cell tumour with thymus-like differentiation (SETTLE). Hence, a multidisciplinary approach must be practised by pathologists, surgeons and radiologists to consider metastatic lesions of the thyroid gland, especially when a previous history of cancer exists or is suspected.

  15. Fulltext Multifocal Primary Neoplasms in Kidney Allografts: Evaluation of Two Cases
    Ellis RJ, Ng KL, Samaratunga H, Del Vecchio SJ, Wood ST, Gobe GC
    J Kidney Cancer VHL, 2016;3(2):14-22.
    PMID: 28326280 DOI: 10.15586/jkcvhl.2016.53
    Renal cell carcinoma (RCC) is the fifth most common malignancy in kidney transplant recipients, with increased risk arising due to immunosuppression. De novo RCC occurrence in kidney allografts is much less common when compared with the native kidneys. Multifocal RCC in allograft kidneys is rarely described. In this report, we discuss two cases of de novo multifocal renal neoplasms in allograft kidneys. Case 1 had three distinct neoplastic lesions of >5 mm, and case 2 had four. Using the World Health Organization 2016 classification of adult renal tumours, case 1 had one clear-cell (cc) RCC (grade 3) and two papillary adenomas; all confined to the kidney. Case 2 had a nodular lesion classified as ccRCC (grade 4) with focal rhabdoid differentiation and some infiltration of renal sinus fat; a cc tubulopapillary RCC; a multilocular cystic renal neoplasm of low malignant potential; and a mucinous tubular and spindle cell carcinoma; the last three all confined to the kidney. This is the first report of mucinous tubular and spindle cell carcinoma in a kidney allograft. When considering multifocal RCC with discordant histology, it is likely that these represent independent tumourigenic events.

    PMID: 22135565 MyJurnal
    Metastatic renal cell carcinoma (RCC) presenting with multiple deposits in the head and neck region is unusual. It is not uncommon for a RCC to metastasise to a distant site after years of a tumour-free period, but most of it would be expected to have a single site of deposit. We report a rare case of a patient who had a nephrectomy 10 years earlier for RCC and presented with tumours in the frontal sinus and posterior pharyngeal wall. Radiological imaging and histology confirmed metastatic RCC at both sites.

  17. Nuclear factor-kappa B subunits and their prognostic cancer-specific survival value in renal cell carcinoma patients
    Ng KL, Yap NY, Rajandram R, Small D, Pailoor J, Ong TA, et al.
    Pathology, 2018 Aug;50(5):511-518.
    PMID: 29935727 DOI: 10.1016/j.pathol.2018.03.003
    Better characterisation and understanding of renal cell carcinoma (RCC) development and progression lead to better diagnosis and clinical outcomes. In this study, expression of nuclear factor-kappa B (NF-κB) subunits: p65 (RelA), p105/p50, p100/p52, and cRel in RCC tissue were compared with corresponding normal kidney, along with tumour characteristics and survival outcome. Ninety-six cases of RCC with paired normal kidney were analysed. Clinicopathological data, demographics and survival data were available. Immunohistochemistry (IHC) for NF-κB subtypes was analysed using the Aperio digital pathology system for overall cellular expression and localisation. The prognostic cancer-specific survival value of the subunits in RCC patients was analysed. Approximately 50% of patients had clinical stage T1, with 22 patients having metastases at presentation. RCC subtypes were: clear cell (n = 76); papillary (n = 11); chromophobe (n = 5); clear cell tubulopapillary (n = 3); and one multilocular cystic RCC. Median follow up was 54.5 months (0.2-135), with 28 deaths at time of analysis. NF-κB p65 had higher overall and nuclear expressions, with lower overall and nuclear expressions of p50, p52 and cRel in RCC compared with normal kidney. Higher expressions of p65 (nuclear), p52 (overall and nuclear) and p50 (overall) correlated significantly with worse cancer-specific survival. This is the first large series of analysis of expression of NF-κB subunits in RCC. Especially with regards to the less studied subunits (p52, p50, cRel), our results allow a better understanding the role of NF-κB in RCC development and progression, and may pave the way for future targeted NF-κB subunit specific therapies.

    Obesity is a recognized risk factor for renal cell carcinoma (RCC) the commonest form of kidney cancer. Both obesity and RCC are serious diseases with increasing incidence yearly. This review examined certain obesity associated measurements and adipokines as detection/prognostic indicators for RCC. The obesity related measurements such as body mass index (BMI), waist circumstance (WC), waist-hip ratio (WHR) in predicting RCC are valid when used in conjunction with other risk factors such as age and sex or with histological findings. The adipokine adiponectin holds promising outcomes as a predictive marker in assessing the risk of developing RCC. In addition, tissue leptin/leptin receptor may be a distinguishing marker for RCC subtypes. However, circulating leptin may not be a suitable detection or prognostic biomarker for RCC. The other less investigated adipokines; omentin, visfatin, apelin and resistin are also expressed in RCC but their prognostic capabilities are still inconclusive. BMI, WC and adipokines may be useful additions in a nomogram which includes TNM staging and pathological grading system to detect, confirm and follow-up RCC cases.

    PMID: 21939176
    We present a case of a middle-aged man who was incidentally found to have right renal solid mass while investigating for his left eye proptosis. Computerised tomography (CT) scan confirmed the diagnosis of renal cell carcinoma and the tumour was successfully excised via open surgery. The histopathology examination revealed the 10x7x8 cm mass to be a clear cell type renal cell carcinoma. The rare presentation of this metastatic renal cell carcinoma, its diagnosis and management will be discussed.
