    Oral sodium phosphate (OSP), an effective bowel purgative, is available over the counter (OTC) and requires a substantially lower volume than polyethylene glycol-based preparative agents. Rarely, OSP consumption has been associated with acute hypocalcemia and hyperphosphatemia. We describe a case of chronic kidney disease patient developing symptomatic hypocalcemia following OTC OSP.

    PMID: 24632917
    Angiomyolipomas (AML) are the most common mesenchymal renal neoplasms arising in the cortex or medulla. Intra-renal and retroperitoneal hemorrhages have been frequently reported. AML can exceptionally involve the renal vein and inferior vena cava. We report a case with extension into the inferior vena cava.

    PMID: 8838120
    Wilms' tumour (nephroblastoma) has been associated with chromosomal abnormalities at the 11p13, 11p15 and 16q regions. A study into the possibility of mutations occurring within p53, the ubiquitous adult tumour suppressor gene, in Wilms' tumour was carried out. Thirty-eight cases were studied. Of these 36 were categorised into the favourable histology group and two into the unfavourable histology group based on the National Wilms' Tumour Study criteria. Archival formalin-fixed, paraffin-embedded tissue sections from each case were stained with a polyclonal (AB565:Chemicon) and a monoclonal (DO7:Dako) antibody raised against p53 protein using a peroxidase-labelled streptavidin biotin kit (Dako). 'Cure' (disease-free survival of 60 months or longer) was documented in 39% of cases with favourable histology tumours. Eleven percent in this group succumbed to the disease. Both cases with unfavourable histology died. Four out of 36 (11%) tumours with favourable histology demonstrated weak to moderate staining with both AB565 and DO7 in more than 75% of tumour cells. In contrast, p53 protein expression in unfavourable histology tumours was significantly increased compared with the favourable histology group (P = 0.021) with both cases demonstrating immunopositivity in > 75% of tumour cells when stained with AB565 and DO7. The intensity of staining ranged from moderate to strong in both cases. It appears from this preliminary study that the immunohistochemical expression of p53 protein in Wilms' tumour, presumably a result of mutation in the p53 tumour suppressor gene, correlates with histological classification, histological categorisation being one of the useful features in the prognostic assessment of Wilms' tumours.

  4. Malignant rhabdoid tumour of the kidney: report of a case showing focal glomeruloid differentiation
    Jayaram G, Looi LM
    Malays J Pathol, 1994 Jun;16(1):83-7.
    PMID: 16329582
    A five-month-old male baby presented with an abdominal mass which was found on computerised tomography (CT) to be involving the left kidney. Nephrectomy and histopathological study showed morphological featues of a malignant rhabdoid tumour. The tumour cells stained strongly for cytokeratin and epithelial membrane antigen and less intensely for vimentin. Electron microscopy revealed concentric whorled arrays of intermediate filaments within the tumour cell cytoplasm. The child was put on post-operative chemotherapy and radiotherapy but developed bilateral lung metastases and died three months after surgery.

    PMID: 1374551
    Clear cell sarcoma of kidney (CCSK) is a rare but distinct tumor of childhood frequently confused with Wilms' tumor (nephroblastoma). It has a characteristic histology, a marked predilection for metastasis to bone, and an aggressive clinical course with a high relapse rate in spite of surgical excision, chemotherapy and radiotherapy. We report the first histologically proven CCSK in a Malaysian patient. This was an 8-mth-old Malay boy who was clinically diagnosed to have stage I Wilms' tumor. Despite treatment, he developed multiple metastases 10 mths after initial presentation and died soon after. Emphasis is placed on recognizing this entity in view of (1) its naturally aggressive behaviour and (2) the prospect of improving prognosis with currently recommended intensified chemotherapeutic regimes. Its immunohistochemical profile of vimentin-positivity and negativity for epithelial membrane antigen, cytokeratin and Factor-8 related antigen is more in favour of a mesenchymal or glomerular origin than a tubular or vascular origin.

  6. Implications of p53 protein expression in clear cell sarcoma of the kidney
    Cheah PL, Looi LM
    Pathology, 1996 Aug;28(3):229-31.
    PMID: 8912350
    Eight histologically-confirmed cases of clear cell sarcoma of the kidney (CCSK) were studied for possible mutations in the p53 tumor suppressor gene by the immunohistochemical demonstration of mutant p53 proteins using a monoclonal (DO7: Dako) and a polyclonal (AB565: Chemicon) antibody to p53 protein. All cases exhibited p53 protein nuclear immunopositivity, although in varying numbers of tumor cells and with different staining intensities. p53 protein (DO7 or AB565) was expressed in < 25% of the tumor cells in four (50%) of the cases, including the one case with a known long term survival of 13 years from the time of diagnosis. The other tumors showed p53 protein immunopositivity in > 25% of the tumor cells when stained with either DO7 or AB565 or both. The intensity of staining, graded on visual impression into weak, moderate or strong, did not correlate well with the ratio of positive staining tumor cells. While this study is unable to clarify the relative prevalence and importance of p53 mutational events in the pathogenesis of this aggressive renal tumor of childhood, it is reasonably suggestive that alterations in the p53 tumor suppressor gene do occur in CCSK.

    Renal cancer is a rare occurrence in all adult malignancies, and renal cell carcinoma (RCC) is the most common type. Due to its aggressive behaviour and high tendency for metastasis, manifestation of RCC varies, often with non-urologic features or symptoms from metastatic sites. Metastatic RCC to the head and neck region is rare particularly to the tongue are extremely rare. We report an elderly lady who presented with recurrent tongue mass metastasis from RCC, a rare cancer with even rarer metastatic site.

  8. Fulltext A retrospective analysis of patients with advanced renal cell carcinoma treated with temsirolimus
    Ng, Christina
    JUMMEC, 2010;13(1):19-23.
    MyJurnal
    The clinical experience of the novel drug temsirolimus on eight patients with metastatic renal cell carcinoma and who were refractory to other forms of treatment is reported. Although none of the patients showed complete or partial response, three patients had stable disease. One patient was prematurely withdrawn due to pneumonitis. Five patients died during the period of observation of twenty months and the median survival time from start of treatment was ten months. Three patients showed no evidence of adverse events (AE). Five patients showed dyslipidemia and two had pneumonitis for which, the drug had to be withdrawn in one of them. None had significant leucopenia. We conclude that temsirolimus has activity even in heavily pretreated patients in advanced renal cell carcinoma and in addition, has the benefits of ease of administration and good tolerability.

    Renal angiomyolipoma, once considered a rare benign renal tumour, is relatively common these days. They account for 0.3-3.0% of all renal masses. Histologically, it is composed of adipose tissue, smooth muscles and blood vessels. Here, we wish to highlight five cases of renal angiomyolipomas which were presented to the University Malaya Medical Centre (UMMC), Kuala Lumpur, Malaysia, over a two-year period between June 2005 and June 2007. This study wish to illustrate its varied clinical presentation and the management undertaken for each underlying condition. These cases were presented in the form of spontaneous perirenal haemorrhage, a large asymptomatic renal mass, a small asymptomatic renal mass, a symptomatic renal angiomyolipoma and a case of renal angiomyolipoma mimicking a renal tumour. Each of these cases varied in its clinical presentation; thus, management has become very challenging to clinicians ranging from conservative management to active intervention, be it operatively or non-operatively.

    Malignancy is a significant long-term complication of successful renal transplantation. Not only the rate is higher but also cases are highly aggressive. We report a case of metastatic, small cell, neuroendocrine tumor in a post-renal transplant patient with progressive left inguinal nodes and right lumbar swellings. He had a remarkably elevated serum lactate dehydrogenase levels with multiple metastatic masses in the left inguinal, left iliac fossa, and right lower abdominal wall on abdominal computed tomography scan. Excisional biopsy of a left inguinal node revealed extensive infiltration with malignant cells in it. Immunohistochemistry staining was positive for synaptophysin, prostatic specific antigen, and CD56. While the primary small cell carcinoma of genitourinary organs is rare, the case illustrates the highly aggressive nature of the disease in a kidney transplant recipient.

  11. 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.

    Metastases, the spread of cancer cells to distant organs, cause the majority of cancer-related deaths. Few metastasis-specific driver mutations have been identified, suggesting aberrant gene regulation as a source of metastatic traits. However, how metastatic gene expression programs arise is poorly understood. Here, using human-derived metastasis models of renal cancer, we identify transcriptional enhancers that promote metastatic carcinoma progression. Specific enhancers and enhancer clusters are activated in metastatic cancer cell populations, and the associated gene expression patterns are predictive of poor patient outcome in clinical samples. We find that the renal cancer metastasis-associated enhancer complement consists of multiple coactivated tissue-specific enhancer modules. Specifically, we identify and functionally characterize a coregulatory enhancer cluster, activated by the renal cancer driver HIF2A and an NF-κB-driven lymphoid element, as a mediator of metastasis in vivo We conclude that oncogenic pathways can acquire metastatic phenotypes through cross-lineage co-option of physiologic epigenetic enhancer states.Significance: Renal cancer is associated with significant mortality due to metastasis. We show that in metastatic renal cancer, functionally important metastasis genes are activated via co-option of gene regulatory enhancer modules from distant developmental lineages, thus providing clues to the origins of metastatic cancer.

  14. 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.

  15. Multiphase renal CT in the evaluation of renal masses: is the nephrographic phase necessary?
    Songib NA, Nazri M, Yaakup NA, Nor HM, Sun Z
    Clin Imaging, 2013 Nov-Dec;37(6):1037-42.
    PMID: 24035803 DOI: 10.1016/j.clinimag.2013.08.005
    The aim of this study is to investigate the feasibility of eliminating the nephrographic phase from the four-phase renal computed tomography (CT) imaging to a three-phase protocol without affecting its diagnostic value. Thirty patients undergoing four-phase renal CT scans for assessment of renal lesions (>10 mm) were included in the study. A three-phase renal CT, without nephrographic phase, had similar diagnostic ability to a four-phase renal CT in the detection and characterization of renal lesions. A three-phase CT (plain, corticomedullary, and excretory phase) is therefore adequate in the clinical diagnosis of renal lesions.

    Renal angiomyolipomas are innocuous benign tumours which rarely behave aggressively. This is a case of a 48 year old Malay lady presenting with right sided abdominal pain associated with a large right sided abdominal mass. She was diagnosed with renal angiomyolipoma of the right kidney complicated by inferior vena caval tumour thrombosis. She successfully underwent a radical nephrectomy and inferior vena caval thrombectomy using cardiopulmonary bypass and deep hypothermic circulatory arrest.

    Malays J Pathol, 1992 Dec;14(2):111-5.
    PMID: 1338998
    Formerly thought to have a constant incidence rate throughout the world, Wilms' tumour (nephroblastoma) has been shown to be less common among Asian children. A retrospective demographic and morphological study of Wilms' tumour histologically diagnosed over a 22-year period at the Department of Pathology, University Hospital, Kuala Lumpur was conducted to assess for inherent demographic and morphological differences between tumours in Malaysian children and those of Western populations. Thirty-seven cases of histologically proven Wilms' tumour qualified for inclusion in this study. 19 patients were Chinese, 13 Malay, 4 Indian and 1 Anglo-asian. 21 were male and 16 were female (M:F ratio = 1.3:1). Their ages ranged from 1 month to 4 years. 70.3% of the patients were below 2 years of age. 36 cases had unilateral and 1 bilateral tumours. Of unilateral tumours, 19 involved the left kidney and 17 the right. Histological assessment, based on criteria of the National Wilms' Tumor Study Group, revealed 20 (52.6%) tumours with a mixed pattern while 8 (21.1%) showed epithelial, 7 (18.4%) blastemal and 3 (7.8%) stromal-predominant patterns. Anaplasia was observed in only 2 tumours (5.3%). There was no obvious difference in age range and sex distribution, laterality of tumours and incidence of anaplasia between this and Western studies. No ethnic predilection was observed. A notably larger percentage of cases were below 2 years of age. Also, a larger proportion of epithelial-predominant and a lower proportion of blastemal-predominant tumours was observed compared with patterns reported from Western populations.

    Histopathology, 1992 Oct;21(4):365-9.
    PMID: 1328018
    Eight cases of clear cell sarcoma of kidney were seen in the Department of Pathology, University Hospital, Kuala Lumpur, Malaysia over the 16-year period from 1973 to 1989. Five of the patients were males. Six patients were Malay, one Chinese and one Indian. The patients' ages ranged from 8 months to 3 years. Clear cell sarcoma was the original diagnosis in two patients while six were diagnosed as blastemal-predominant Wilms' tumours at presentation. Metastases developed in five patients. Metastatic sites included the thoracic vertebra, skull, orbit, humerus, radius, ulna, shoulder, lung and liver. The prolonged survival, of 9 years and 9 months, seen in one patient despite omission of Adriamycin (doxorubicin) from the chemotherapeutic protocol is highlighted. We also emphasise the histological factors which are of help in differentiating clear cell sarcoma from Wilms' tumour.

    PMID: 30580362
    INTRODUCTION: Cyclooxygenase-2 (COX-2) promotes carcinogenesis by inducing proliferation and angiogenesis while decreasing apoptosis and immunosuppressive activity. It is overexpressed in many malignancies including renal cell carcinoma (RCC). The aim of this study was to investigate COX-2 expression in clear cell RCC and its association with tumour grades and demographic parameters.

    MATERIALS AND METHODS: Thirty-six clear cell RCC cases were selected. There were 21 (58.3%) men and 15 (41.7%) women with median age of 56.6 years (range: 16-74 years). Chinese constituted 16 (44.4%) of the cases; Malays 14 (38.9%) cases and Indian 6 (16.7%) cases. There were 6 (16.7%) grade 1, 20 (55.6%) grade 2, 10 (27.8%) grade 3 and none was grade 4. The paraffin embedded tissues were cut at 4 μm thick and stained with COX-2 monoclonal antibody.

    RESULTS: Eighteen (50%) of the RCC cases were immunopositive, of which all showed strong positivity. The immunopositive cases showed cytoplasmic membrane positivity.

    CONCLUSION: There was no significant association between COX-2 expression with grade, age, sex and ethnicity (p=0.457, p=0.054, p=0.389 and p=0.568 respectively). Strong positivity of COX-2 suggest that COX-2 may play a role in cell proliferation and in carcinogenesis.

  20. An immunohistochemical study comparing clear cell sarcoma of the kidney and Wilms' tumor
    Looi LM, Cheah PL
    Pathology, 1993 Apr;25(2):106-9.
    PMID: 8396229
    This study explores immunohistochemical characteristics that may be of diagnostic value in differentiating clear cell sarcoma of the kidney (CCSK) from Wilms' tumor (WT) and may provide some insight into the histogenesis of CCSK. Formalin-fixed, paraffin-embedded sections of 8 CCSK and 9 WT were stained, using the standard avidin-biotin peroxidase complex method, for vimentin (VIM), Factor-8 related antigen (F8A), epithelial membrane antigen (EMA), desmin (DES), S-100 protein and Mac 387. CCSK cells consistently exhibited moderate to strong diffuse cytoplasmic positivity for VIM and were negative for F8A, EMA, DES, S-100 and Mac 387. In contrast, only patchy groups of stromal cells and primitive glomeruloid structures in WT exhibited VIM-positivity. Blastemal cells were VIM-negative. Stromal cells with rhabdomyomatous differentiation exhibited cytoplasmic positivity for DES. Epithelial cells of maturing tubular structures showed EMA-positivity whereas immature tubular structures were EMA-negative. Neither blastemal, stromal nor epithelial elements in WT were positive for F8A, S-100 or Mac 387. Podocytes and mesangial cells of glomeruli in 3 mid-trimester human abortuses (controls) exhibited moderate to strong VIM-positivity. The importance of differentiating CCSK from WT has been repeatedly emphasized because of its poorer prognosis and the necessity of adding Adriamycin to the chemotherapeutic regime. The consistent VIM-positivity of CCSK cells can be a useful feature in differentiating it from "blastemal-predominant" WT, with which it is often confused. Although vimentin expression by CCSK cells is consistent with a mesenchymal character, the possibility of a histogenetic link with glomerular podocytes or mesangial cells should also be considered.
