[Title] Renal cell carcinoma and intradural spinal metastasis with cauda equina infiltration: case report--part II.

OBJECTIVE: To describe the diagnosis, pathophysiology, and treatment of a papillary renal cell carcinoma that developed an intradural spinal mass with cauda equina infiltration.

SUMMARY OF BACKGROUND DATA: Cancers that metastasize intradurally to the spinal canal are uncommon, accounting for the 6% of all spinal metastases.

Those from renal cell carcinoma are especially unusual.

Only 3 reports that describe the spread of metastatic renal cell carcinoma to the cauda equina have been published to our knowledge.

METHODS: A female patient had undergone nephrectomy for the treatment of the papillary renal cell carcinoma 2 years before, and only 1 localization (at the genital tract) was previously diagnosed.

CONCLUSIONS: The majority of cauda equina tumors are primary tumors, and metastases are very rare.

To our knowledge, this is the fourth case described of metastasis of renal cell carcinoma at the cauda equina and the first of papillary type.

[Title] Imaging features of von Hippel-Lindau disease.

von Hippel-Lindau (VHL) disease is a rare, autosomal dominantly inherited multisystem disorder characterized by development of a variety of benign and malignant tumors.

The spectrum of clinical manifestations of the disease is broad and includes retinal and central nervous system hemangioblastomas, endolymphatic sac tumors, renal cysts and tumors, pancreatic cysts and tumors, pheochromocytomas, and epididymal cystadenomas.

The most common causes of death in VHL disease patients are renal cell carcinoma and neurologic complications from cerebellar hemangioblastomas.

Screening is important because the lesions in VHL disease are treatable; thus, early detection allows use of more conservative therapy and may enhance the patient's length and quality of life.

A multidisciplinary team approach is important in screening for VHL disease.

[Title] Renal and adrenal tumours in children.

The differential diagnosis of renal and supra-renal masses firstly depends on the age of the child.

Neuroblastoma (NBL) may be seen antenatally or in the newborn period; this tumour has a good prognosis unlike NBL seen in older children (particularly NBL in those aged 2-4 years).

Benign renal masses predominate in early infancy but beyond the first year of life Wilms' tumour is the most common renal malignancy, until adolescence when renal cell carcinoma has similar or increased frequency as children get older.

Adrenal adenomas and carcinomas also occur in childhood; these tumours are indistinguishable on imaging but criteria for the diagnosis of adrenal carcinoma include size larger than 5 cm, a tendency to invade the inferior vena cava and to metastasise.

The most topical dilemmas in the radiological assessment of renal and adrenal tumours are presented.

Topics covered include a proposed revision to the staging of NBL, the problems inherent in distinguishing nephrogenic rests from Wilms' tumour and the current recently altered approach regarding small lung nodules in children with Wilms' tumour.

[Title] Chemokines as therapeutic targets in renal cell carcinoma.

Targeting novel pathways associated with tumor angiogenesis, invasion and immunity, may lead to improvement in patient outcomes for renal cell carcinoma.

Chemokines potentiate tumor growth, metastasis, angiogenesis and immune evasion through interactions with stromal cells and neoplastic cells.

Further understanding of the mechanisms involved in chemokine-mediated angiogenesis and metastasis may lead to improved therapeutic strategies in this disease.

Interactions between chemokine expression and signaling, and the VEGF and hypoxia-inducible factor pathways offer important opportunities to intervene in the process of renal cell carcinoma proliferation, angiogenesis and invasion.

Modulation of the CXCR3/CXCR3-ligand or the CXCR4/CXCL12 biologic axis may be potential therapeutic targets for the treatment of renal cell carcinoma.

Furthermore, combination treatment with agents targeting chemokine signaling with therapies directed at angiogenesis and tumor immunity may lead to improved outcomes in this disease.

[Title] History of treated hypertension and diabetes mellitus and risk of renal cell cancer.

BACKGROUND: An increased risk of renal cell cancer (RCC) has been reported in subjects with hypertension.

Whether this association may vary according to sex, smoking, obesity, or RCC clinical presentation is unclear.

Results on the link between diabetes mellitus and RCC are inconclusive.

PATIENTS AND METHODS: We conducted an Italian multicenter case-control study, including 767 (494 men, 273 women) incident cases of RCC, under 80 years of age, and 1534 hospital controls, frequency-matched to cases.

Multiple logistic regression models, conditioned to center, sex, and age, and adjusted for period of interview, education, smoking, and body mass were used to estimate odds ratios (OR).

RESULTS: Compared with subjects never treated, patients with a history of treated hypertension [OR = 1.7, 95% confidence interval (CI) 1.4-2.1] reported an excess risk of RCC.

This pattern was confirmed in different strata of sex, education, smoking habits, body mass, tumor histological type, stage, or grade.

The attributable risk of RCC for treated hypertension in this population was 16%.

CONCLUSION: A possible causal role of hypertension in renal cell carcinogenesis is supported by the consistency of the direct association.

[Title] Identification of fatty acid binding proteins as markers associated with the initiation and/or progression of renal cell carcinoma.

Renal cell carcinoma (RCC) representing the most common neoplasia of the kidney in Western countries is a histologic diverse disease with an often unpredictable course.

The prognosis of RCC is worsened with the onset of metastasis, and the therapies currently available are of limited success for the treatment of metastatic RCC.

Although gene expression analyses and other methods are promising tools clarifying and standardizing the pathological classification of RCC, novel innovative molecular markers for the diagnosis, prognosis, and for the monitoring of this disease during therapy as well as potential therapeutic targets are urgently needed.

Using proteome-based strategies, a number of RCC-associated markers either over-expressed or down-regulated in tumor lesions in comparison to the normal epithelium have been identified which have been implicated in tumorigenesis, but never linked to the initiation and/or progression of RCC.

These include members of the fatty acid binding protein family, which have the potential to serve as diagnostic or prognostic markers for the screening of RCC patients.

[Title] Efficacy and safety of sorafenib in patients with advanced renal cell carcinoma with and without prior cytokine therapy, a subanalysis of TARGET.

Before the development of targeted therapies, administration of cytokines (e.g., interleukin-2, interferon-alpha) was the primary systemic treatment option for advanced renal cell carcinoma.

Sorafenib, an oral targeted, multikinase inhibitor, significantly prolonged progression-free survival and overall survival in the Treatment Approaches in Renal Cancer Global Evaluation Trial (TARGET), a large (N = 903) phase III, double-blind, randomised, placebo-controlled study of patients with advanced renal cell carcinoma resistant to standard therapy.

Sorafenib demonstrated a consistent, significant clinical benefit against advanced renal cell carcinoma, with a twofold improvement in progression-free survival and disease control rate, with similar toxicities in patients with or without prior cytokine treatment.

[Title] [Systemic therapy of metastatic renal cell carcinoma].

Cytokine-based immunotherapy was the only viable option in metastatic, nonresectable renal cell carcinoma (RCC) for many years.

In this context, interleukin-2 (IL-2) and interferon-alpha (IFN-alpha) turned out to be the most effective single agents in RCC.

Such small molecules like tyrosine kinase inhibitors, monoclonal antibodies, or the mTOR inhibitor CCI-779 may dramatically change the established concepts of systemic RCC treatment.

This paper gives an overview of established, current, and evolving concepts of systemic therapy in RCC.

[Title] Stauffer's syndrome with jaundice, a paraneoplastic manifestation of renal cell carcinoma: a case report.

OBJECTIVE: To report an infrequent case of Stauffer's Syndrome with jaundice as a paraneoplastic syndrome of a metastatic renal cancer.

METHODS: We describe the set up of cholestatic jaundice without neoplastic liver infiltration in a patient with a metastatic renal cell carcinoma, which turned back with surgery and systemic treatment.

RESULTS: Proper treatment of baseline disease enables turn back paraneoplastic signs and symptoms of Stauffer's Syndrome.

CONCLUSIONS: Reversible cholestatic jaundice without evidence of hepatic disease is an infrequent form of the Stauffer's syndrome.

This paraneoplastic syndrome is associated particularly with renal carcinoma but was described in lymphoproliferative diseases, prostate cancer and broncogenic tumors.

[Title] Neuroendocrine breast carcinoma metastatic to renal cell carcinoma and ipsilateral adrenal gland.

We report on a 60-year-old woman with neuroendocrine carcinoma of the left breast metastasizing to renal cell carcinoma (RCC) of the left kidney and to adrenal gland.

A yellow, well-circumscribed tumor, 11 cm in largest diameter and limited to the kidney, was found.

Histopathology revealed RCC with foci of neuroendocrine differentiation.

Solid sheets of hyperchromatic epithelioid cells with high mitotic activity were found between typical clear cells of RCC.

These cells were CAM5,2 and E-cadherin focally positive, synaptophysin and NSE weakly positive, CK19 moderately positive, and AE1-AE3 and EMA strongly positive.

The left adrenal gland contained multiple, separate foci of a tumor composed of neuroendocrine components.

Because of the biphasic tumor in the kidney, extensive clinical examination and further analyses were recommended.

Tumor in the left breast was revealed.

The tumor was histologically and immunohistochemically similar to the neuroendocrine component within RCC.

To our knowledge, this is the first case of neuroendocrine breast carcinoma with metastasis to renal cell carcinoma and ipsilateral adrenal gland.

[Title] Preoperative prognostic nomogram (probability table) for renal cell carcinoma based on TNM classification.

PURPOSE: Recently several prognostic nomograms have been developed to predict the prognosis of malignant diseases, including renal cell carcinoma.

However, to our knowledge a preoperative prognostic nomogram that predicts survival in patients with renal cell carcinoma is not available.

We developed a preoperative nomogram based on the TNM classification that predicts cause specific survival in patients with renal cell carcinoma.

MATERIALS AND METHODS: A total of 545 patients with renal cell carcinoma, including metastatic disease, who underwent radical nephrectomy or nephron sparing surgery at our institution were included in the study.

Cases were staged according to the 2002 UICC TNM system, 6th edition.

CONCLUSIONS: The preoperative information shown by this nomogram may be important for obtaining informed consent from patients with renal cell carcinoma who have indications for surgery.

[Title] Dysregulation of kallikrein-related peptidases in renal cell carcinoma: potential targets of miRNAs.

Renal cell carcinoma (RCC) accounts for 3% of all adult malignancies and currently no diagnostic marker exists.

Kallikrein-related peptidases (KLKs) have been implicated in numerous cancers including ovarian, prostate, and breast carcinoma.

KLKs 5, 6, 10, and 11 have decreased expression in RCC when compared to normal kidney tissue.

Our bioinformatic analysis indicated that the KLK 1, 6, and 7 genes have decreased expression in RCC.

We experimentally verified these results and found that decreased expression of KLKs 1 and 3 were significantly associated with the clear cell RCC subtype (p<0.001).

An analysis of miRNAs differentially expressed in RCC showed that 61 of the 117 miRNAs that were reported to be dysregulated in RCC were predicted to target KLKs.

Transfection of miR-224 into HEK-293 cells resulted in decreased KLK1 protein levels.

A luciferase assay demonstrated that hsa-let-7f can target KLK10 in the RCC cell line ACHN.

Our results, showing differential expression of KLKs in RCC, suggest that KLKs could be novel diagnostic markers for RCC and that their dysregulation could be under miRNA control.

[Title] Histologic predictors of renal cell carcinoma response to interleukin-2-based therapy.

The authors examined pathology from patients with renal cancer (RCC) treated with IL-2 to determine response rates for clear cell and variant RCC and to identify histologic features that predict response.

Of 163 primary RCCs, the response rate was 21% (30/146) for patients with clear cell versus 6% (1/17) for patients with variant or indeterminate type RCC (P = 0.20).

For clear cell carcinomas, response to IL-2 was associated with the presence of alveolar features and the absence of papillary and granular features.

Patients with more than 50% alveolar features and no granular or papillary features had a 39% response rate (14/36).

Patients with alveolar and granular features representing less than 50% of the specimen and no papillary features had a 19% response rate (15/77).

Response rates in the three prognostic groups and for patients with non-clear cell cancers were 25% (5/20), 9% (2/22), 0% (0/16), and 0% (0/10), respectively.

Median survivals for all patients with clear cell tumors by risk group were 2.87, 1.36, and 0.87 years, respectively (P < 0.001).

These data suggest that patients with non-clear cell RCC or with clear cell RCC with papillary, no alveolar, and/or more than 50% granular features respond poorly to IL-2 and should be considered for alternative treatments.

Investigation of other tumor-related predictors of IL-2 responsiveness is warranted.

[Title] Adult Xp11 translocation renal cell carcinoma diagnosed by cytogenetics and immunohistochemistry.

PURPOSE: To determine the incidence of Xp11 translocation renal cell carcinoma (RCC) in adult patients using cytogenetics and immunohistochemstry.

EXPERIMENTAL DESIGN: Cytogenetic studies were prospectively done using tumor samples from 443 consecutive adult Japanese patients (ages 15-89 years) who underwent nephrectomy for RCC.

Clinicopathologic characteristics of Xp11 translocation RCC were examined.

RESULTS: Mitotic cells suitable for cytogenetic analysis were obtained in 244 tumor samples (55%); among these, we identified 4 cases (1.6%) of Xp11 translocation RCC.

The median age of the 7 patients was 41 years (range, 15-59 years), and 15% of RCC patients (4 of 26) who were younger than ages 45 years had this type of RCC.

Of the four Xp11 translocation RCC patients whose karyotypes were determined, two had an ASPL-TFE3 gene fusion.

Of these 2, 1 had pulmonary metastasis at presentation, and the other developed liver metastasis 12 months after nephrectomy and died of the disease.

Both had nodal involvement but remained disease free for 3 and 5 years, respectively, after surgical resection of lymph node metastases.

CONCLUSIONS: This is the first report to determine the incidence of Xp11 translocation RCC in adult patients.

We found that this disease is relatively common in young adults.

[Title] [Clinicopathologic study of renal cell carcinoma with rhabdoid features].

OBJECTIVE: To study the clinicopathologic features and biologic behavior of renal cell carcinoma (RCC) with rhabdoid features.

METHODS: Ten cases of RCC with rhabdoid features collected during the period from 1995 to 2005 were enrolled into the study.

Histologically, the rhabdoid foci were characterized by loosely cohesive trabeculae, acini, lobules and clusters of rhabdoid cells in otherwise clear cell RCC (9 cases) or papillary RCC (1 case).

The rhabdoid cells were round to polygonal in shape and contained globular eosinophilic inclusion bodies in the cytoplasm, eccentric nuclei, vesicular chromatin pattern and prominent nucleoli.

Coagulative tumor necrosis was commonly seen.

Immunohistochemical study showed that the rhabdoid cells were diffusely positive for CD10 (10/10), cytokeratin AE1/AE3 (10/10), epithelial membrane antigen (10/10) and vimentin (10/10).

The mean Ki-67 labeling index of the rhabdoid component was higher than that of the non-rhabdoid component (P < 0.05).

While 6 patients are still alive without recurrence, 2 patients died of the disease 6 and 29 months respectively after the operation.

CONCLUSIONS: RCC with rhabdoid elements are mainly observed in clear cell RCC and need to be distinguished from oncocytic renal tumors and malignant rhabdoid tumor of kidney.

[Title] Tuberous sclerosis and the kidney: from mesenchyme to epithelium, and beyond.

The renal manifestations of tuberous sclerosis complex (TSC) are remarkably diverse, including polycystic kidney disease, oncocytomas, renal cell carcinomas, and both benign and malignant angiomyolipomas.

What is particularly unusual about TSC, setting it apart from virtually all other inherited forms of renal disease, is the abnormalities of both mesenchymal cells (angiomyolipomas) and epithelial cells (cysts, oncocytomas, and carcinomas).

Recently, the TSC1/TSC2 protein complex was shown to inhibit the kinase mTOR (mammalian target of rapamycin).

This places TSC1/TSC2 at center stage in signaling pathways that regulate cell growth.

Here, we will address the genetic, cellular and biochemical mechanisms that may contribute to the unusually broad spectrum of renal disease in cells with TSC1 or TSC2 mutations, and consider how the TSC signaling pathways may be linked to other renal diseases such as polycystic kidney disease and renal cell carcinoma.

[Title] Efficacy and safety of TachoSil as haemostatic treatment versus standard suturing in kidney tumour resection: a randomised prospective study.

OBJECTIVE: Elective nephron-sparing surgery (NSS) for renal cell carcinoma (RCC) has gained general acceptance as an alternative to radical nephrectomy.

To achieve haemostasis without risk of local ischaemia and necrosis of kidney parenchyma after standard haemostatic suturing, we investigated TachoSil's efficacy and safety as atraumatic haemostatic treatment after kidney tumour resection.

METHODS: A total of 185 patients scheduled for NSS for small, superficial kidney tumours were included in an open, randomised, prospective, multicentre, parallel-group trial.

CONCLUSION: TachoSil was superior to standard suturing in obtaining intraoperative control of haemorrhage and was as well tolerated as standard haemostatic treatment during NSS.

[Title] Prognostic significance of perinephric fat infiltration and tumor size in renal cell carcinoma.

PURPOSES: It is controversial that perinephric fat infiltration has an impact on survival in patients with renal cell carcinoma.

Therefore, we evaluated the influence of perinephric fat infiltration and tumor size on patient survival.

MATERIALS AND METHODS: We retrospectively reviewed the medical records of 783 and 77 patients with pT1-2 (cN0M0) and pT3a (cN0M0) renal cell carcinoma, respectively.

Sporadic unilocular noncystic renal cell carcinoma was included.

Univariate and multivariate analyses of prognostic factors, including perinephric fat infiltration, on cancer specific and disease-free survival were performed.

RESULTS: Patients with pT1-2 and pT3a tumors had a 5-year cancer specific survival rate of 96.1% and 84.9%, and a 5-year disease-free survival rate of 93.4% and 74.7%, respectively (each p <0.01).

Age, tumor size and Fuhrman nuclear grade were independent prognostic factors for cancer specific and disease-free survival, whereas perinephric fat infiltration was significant only for disease-free survival.

However, perinephric fat infiltration had a significant effect on cancer specific survival in patients with pT3a tumors more than 7 cm (p = 0.001).

In contrast, patients with pT3a tumors 7 cm or less had cancer specific and disease-free survival similar to that of patients with pT2 tumors.

Recurrence of pT3a tumors greater than 7 cm was observed in 44% of patients but in only 14.6% of those with pT3a tumors 7 cm or less (p = 0.029).

In contrast to the recurrence of tumors 7 cm or less, recurrence of pT3a tumors more than 7 cm usually developed at multiple sites with a large tumor burden and it progressed rapidly.

Consequently 85% of patients with recurrence of pT3a tumors larger than 7 cm died of renal cell carcinoma compared with 33% of those with recurrence of pT3a tumors 7 cm or less (p = 0.001).

CONCLUSIONS: In pT3a renal cell carcinoma tumor size was the strongest prognostic factor of disease-free and cancer specific survival.

Perinephric fat infiltration was an independent prognostic factor for disease-free survival but not for cancer specific survival due to the less aggressive behavior of small (7 cm or less) pT3a tumors after recurrence.

Tumor size and perinephric fat infiltration should be included in T3a renal cell carcinoma staging.

[Title] The role of lymph node dissection in renal cell carcinoma: the pendulum swings back.

The incidence of regional lymph node metastases in patients with renal cell carcinoma ranges from 13% to over 30%, and portends a poor prognosis in both locally advanced and metastatic settings.

Patients with small, organ confined tumors are at low risk for regional lymph node metastases and lymph node dissection can be omitted in these patients.

Patients with locally advanced primary tumors but no clinical evidence of lymphadenopathy can be selectively targeted for aggressive lymph node dissection as an adjunct to radical nephrectomy, based on their individual risk of harboring micrometastatic lymph node disease.

Although early identification of micrometastatic nodal disease in this group of patients has not conclusively been shown to improve survival, accurate pathologic nodal staging allows for early implementation of adjuvant systemic therapies in these high-risk patients.

[Title] Long-lasting remission of pulmonary metastases of renal cell cancer under IFN-beta therapy in a patient with multiple sclerosis.

BACKGROUND: Immunomodulary therapy based on interferon (IFN)-a has been shown to be effective in a subset of patients with advanced renal cell carcinoma (RCC).

IFN-Beta has occasionally been reported to induce remissions in RCC, but is well established in the treatment of multiple sclerosis (MS).

There is an ongoing debate whether hyperactivation of the immune system may convey protection against the development of cancer in MS patients.

PATIENTS AND METHODS: A 54-year-old female MS patient underwent tumor nephrectomy for RCC in 1994.

CONCLUSION: To our knowledge, this is the longest remission under IFN-Beta treatment ever reported in an RCC patient.

We conclude that IFN-Beta should be particularly considered as a therapeutic option in the rare occasion of metastatic RCC in patients with MS.

Rutaceline was evaluated for its antiproliferative capacity on the human colorectal adenocarcinoma (Caco-2) and the African green monkey kidney (Vero) cell lines.

The 50% inhibition of cell growth (IC50) obtained after 24 h incubation was similar for both cells lines (110-115 microg/ml, i.e.

269-281 microM), but at 48 h the IC50 value for the Caco-2 cells was lower than for the Vero cells (20 microg/lml, i.e.

220 microM) indicating a higher cell growth inhibitory effect on the colon adenocarcinoma cells.

At the respective IC50 concentrations, Rutaceline did not significantly induce apoptosis but induced cell cycle arrest in the GO/G1 phase, as well as a decrease of cells in S phase.

Rutaceline also induced DNA fragmentation in both cell lines, as revealed by agarose gel electrophoresis, and a dose-dependent clastogenic effect in both cell lines as revealed by the Comet assay.

[Title] Resection of recurrent inferior vena cava tumor after radical nephrectomy for renal cell carcinoma.

Management of recurrent tumor in the inferior vena cava (IVC) after radical nephrectomy is surgically challenging.

We report 3 cases of recurrent renal cell carcinoma within the IVC managed by three different surgical techniques.

One patient was treated with tumor thrombus removal and primary cavotomy closure.

Although technically difficult, repeat resection of IVC tumor recurrence after nephrectomy for renal cell carcinoma is an acceptable method of treatment.

[Title] [Experiences of open transperitoneal radical nephrectomy for large renal masses].

OBJECTIVE: To evaluate the effect of technical improvements of transperitoneal radical nephrectomy on the patients with large renal cell carcinoma.

METHODS: From May 2002 until May 2009, 45 patients with large (> 12 cm) renal cell carcinoma underwent transperitoneal radical nephrectomy.

The modified operative methods included exposing the operative field via a liver retractor and initially ligating renal artery to block the blood supply of kidney and tumor.

The method of tumor-free tissue dissociation was applied.

RESULTS: The tumor diameter was from 12.2 cm to 28.3 cm with a mean of 14.5 cm.

The pathological diagnoses were all of renal cell carcinoma.

The pathological stage included T(2)N(0 approximately 1)M(0 approximately 1)(n = 13), T(3)N(0 approximately 1)M(0 approximately 1)(n = 23), T(4)N(0 approximately 1)M(0 approximately 1)(n = 9).

After a follow-up period of 3 - 63 months, 3 cases of tumor recurrence were found in primary renal clutch.

CONCLUSION: Improved radical nephrectomy is feasible for large renal cell carcinoma.

[Title] Tuberin haploinsufficiency is associated with the loss of OGG1 in rat kidney tumors.

BACKGROUND: Tuberous sclerosis complex (TSC) is caused by defects in one of two tumor suppressor genes, TSC-1 or TSC-2.

TSC-2 gene encodes tuberin, a protein involved in the pathogenesis of kidney tumors.

Loss of heterozygosity (LOH) at the TSC2 locus has been detected in TSC-associated renal cell carcinoma (RCC) and in RCC in the Eker rat.

Tuberin downregulates the DNA repair enzyme 8-oxoguanine DNA-glycosylase (OGG1) with important functional consequences, compromising the ability of cells to repair damaged DNA resulting in the accumulation of the mutagenic oxidized DNA, 8-oxo-dG.

Loss of function mutations of OGG1 also occurs in human kidney clear cell carcinoma and may contribute to tumorgenesis.

We investigated the distribution of protein expression and the activity of OGG1 and 8-oxo-dG and correlated it with the expression of tuberin in kidneys of wild type and Eker rats and tumor from Eker rat.

RESULTS: Tuberin expression, OGG1 protein expression and activity were higher in kidney cortex than in medulla or papilla in both wild type and Eker rats.

In kidney tumors from Eker rats, the loss of the second TSC2 allele is associated with loss of OGG1 expression.

Immunostaining of kidney tissue shows localization of tuberin and OGG1 mainly in the cortex.

CONCLUSION: These results demonstrate that OGG1 localizes with tuberin preferentially in kidney cortex.

In addition, the predominant expression of OGG1 in the cortex and its decreased expression and activity in the Eker rat may account for the predominant cortical localization of renal cell carcinoma.

[Title] Ubiquitin COOH-terminal hydrolase 1: a biomarker of renal cell carcinoma associated with enhanced tumor cell proliferation and migration.

PURPOSE: Renal cell carcinoma (RCC) accounts for 2% to 3% of all malignancies.

It represents one of the most radiation- and chemotherapy-resistant tumors and surgical resections are only effective in organ-defined disease.

However, RCC is an immunogenic tumor with response rates to immunotherapies between 10% and 20% of the treated patients.

Due to the currently inefficient therapies and the low 5-year survival rates of RCC patients, novel diagnostic, prognostic, and therapeutic markers are urgently needed for this disease.

EXPERIMENTAL DESIGN: Proteome-based approaches were used to identify (a) differentially expressed proteins in RCC compared with normal kidney epithelium and (b) proteins that are able to induce an antibody response in RCC patients.

RESULTS: The ubiquitin COOH-terminal hydrolase L1 (UCHL1) was found to be differentially expressed in both RCC lesions and RCC cell lines and immunoreactive using patients' sera.

UCHL1 expression was often down-regulated in primary RCC when compared with normal kidney epithelium but dependent on the RCC subtype, the von Hippel-Lindau phenotype, and the tumor grading.

Moreover, the frequency and the level of UCHL1 expression were higher in metastases when compared with primary RCC lesions.

Gain-of-function transfectants exhibited a significant higher proliferation and migration rate than UCHL1-negative RCC cells.

CONCLUSIONS: UCHL1 expression seems to be associated with the metastatic phenotype of RCC and therefore might serve as potential biomarker for the diagnosis and prognosis of RCC patients.

[Title] [Pathological prognostic indicators in renal cell carcinoma].

[Transliterated title] Indicadores pronósticos anatomopatológicos del cáncer de riñón.

OBJECTIVE: To analyze histological factors not routinely assessed as potential prognostic factors in renal cell carcinoma, such as tumor necrosis, microscopic vascular invasion, and sinus fat invasion.

MATERIALS AND METHODS: A retrospective, analytical study was conducted of surgical specimens from 139 patients with localized renal cell carcinoma who underwent nephrectomy from 1993 to 2005.

Tumor necrosis, microscopic vascular invasion, and sinus fat invasion were analyzed and compared to the classical factors: TNM classification, Fuhrman grade, and tumor size.

For statistical analysis, variables analyzed were categorized as pT1, 2 vs pT3, 4; Fuhrman grade 1, 2 vs 3, 4; tumor size < 7 cm vs >or= 7cm; tumor necrosis vs no tumor necrosis; microvascular invasion of sinus fat vs no invasion.

Cancer-specific survival probability and disease-free survival were calculated.

Dependent variables were used to analyze cancer-specific survival rates.

Disease-free survival was estimated using a Cox regression model and Kaplan-Meier curves.

RESULTS: In the univariate analysis, all variables analyzed had a significant influence on death for renal cell carcinoma.

The variables significantly influencing disease-free survival, estimated by the Cox method, were the pT stage (p = 0.038) and Fuhrman grade (p = 0.048).

CONCLUSIONS: In patients with clinically localized renal cell carcinoma undergoing nephrectomy, pT stage and Fuhrman grade are the most important prognostic factors for survival and disease-free survival.

Tumor necrosis, microscopic vascular invasion, and sinus fat invasion are prognostic factors for death from renal carcinoma which are associated to TNM classification, Fuhrman grade, and tumor size.

[Title] Renal oncocytoma with bilateral synchronous renal cell carcinoma in a patient undergoing long-term hemodialysis.

We report a case of bilateral synchronous renal cell carcinoma and renal oncocytoma in a 56-year-old male who had been treated with hemodialysis for 32 years.

Because anemia gradually worsened, computed tomography and magnetic resonance imaging were carried out and revealed bilateral renal tumors within acquired cystic disease of the kidney.

Bilateral nephrectomy was carried out, and the patient was diagnosed with multiple renal cell carcinomas and a single renal oncocytoma.

To our knowledge, this is the first reported case of renal oncocytoma with synchronous renal cell carcinoma in a patient undergoing long-term hemodialysis.

[Title] Overexpression of the myc target gene Mina53 in advanced renal cell carcinoma.

The myc target gene Mina53 was reported to be overexpressed in esophageal cancer with a poor prognosis.

The purpose of the present study was to examined Mina53 expression and its relationship to clinicopathological parameters in human renal cell carcinoma (RCC).

Mina53 and Ki-67 expression was examined on immunohistochemistry for 64 surgically resected RCC and non-cancerous tissue.

In addition, the relationship between Mina53 expression and clinicopathological prognostic factors of RCC such as age, stage, microvenous invasion (MVI), histological subtype, Ki-67 labeling index (LI), and prognosis, was examined.

Mina53 was expressed in the nuclei of tumor cells and tubular nuclei of normal renal tissue.

The expression level of Mina53 was significantly higher in patients with poor prognostic factors (stage IV, MVI-positive, and sarcomatoid RCC, and high Ki-67 LI).

The prognosis of high Mina53-expressing tumors was significantly poorer than that of non-Mina53-high tumors (P < 0.0001).

In conclusion, Mina53 is overexpressed in RCC tissue from patients with poor prognostic factors, suggesting that Mina53 overexpression is one of the factors for poor prognosis in RCC.

[Title] [Outcome of surgical management of renal cell carcinoma with renal vein or inferior vena cava tumor thrombus].

OBJECTIVE: To investigate the prognosis of surgical treatment for renal cell carcinoma with renal vein or inferior vena cava tumor thrombus.

METHODS: Between August 1994 and July 2004, 33 patients with renal cell carcinoma with renal vein or inferior vena cava tumor thrombus underwent radical nephrectomy and thrombectomy.

Level of tumor thrombus was renal vein in 15 patients, infrahepatic (level I) in 9, intrahepatic (level II) in 5, suprahepatic (level III) in 1, and right atrial extension (level IV) in 3.

The mean survival time of patients with renal vein involvement [(49.9 +/- 9.8) months] versus level I [(16.7 +/- 1.9) months] was significantly different (P < 0.05).

CONCLUSIONS: Radical nephrectomy plus thrombectomy is a valuable method for the treatment of renal cell carcinoma with renal vein or inferior vena cava involvement.

Patients with renal vein tumor thrombus appear to have better survival compared to patients with inferior vena cava tumor thrombus.

[Title] Critical role of fine needle aspiration cytology and immunocytochemistry in preoperative diagnosis of pediatric renal tumors.

OBJECTIVE: To evaluate accuracy and role of immunocytochemistry (ICC) in cytologic diagnosis of pediatric renal tumors.

STUDY DESIGN: Fine needle aspirates from 75 cases of pediatric renal tumors were studied.

Smears were screened without the knowledge of final histologic diagnosis.

Subsequently, clinical details, final histology and diagnosis rendered by the original cytologist were noted to judge accuracy of diagnosis by a sensitized cytologist.

Five neuroblastomas that entered close differentials for Wilms tumor were also evaluated.

RESULTS: Of 58 Wilms tumors, 5 were misdiagnosed; 3 renal rhabdoid tumors and 1 clear cell sarcoma were missed on cytology.

Non-Hodgkin's lymphomas presenting as renal masses were accurately diagnosed on cytology, but primitive neuroectodermal tumors (n = 3) and renal cell carcinomas (n = 2) were not accurately diagnosed.

Accuracy rate improved from 65% to 92% on review by a cytologist aware of cytologic features of pediatric renal tumors.

CONCLUSION: A good accuracy rate of diagnosis of pediatric renal tumors can be achieved by priming pathologists to typical features of tumors.

Immunocytochemistry plays a supportive role in cases with atypical morphology or unusual presentations.

[Title] Von Hippel-Lindau gene product modulates TIS11B expression in renal cell carcinoma: impact on vascular endothelial growth factor expression in hypoxia.

TIS11B has been shown to regulate vascular endothelial growth factor (VEGF) mRNA stability in adrenocorticotropic hormone-stimulated primary adrenocortical cells.

TIS11B has also been documented as a negative regulator of VEGF during development, but nothing has yet been reported in the context of human cancers.

The Von Hippel-Lindau (VHL) tumor suppressor protein regulates VEGF gene expression at both the transcriptional and post-transcriptional levels in normoxia.

Here, we report a unique regulatory function of VHL in VEGF expression in hypoxia that is mediated through modulation of TIS11B protein levels in renal cancer cells.

In normoxia, we detected increased expression of the microRNA hsa-miR-29b in the VHL-overexpressing renal cancer cell line 786-O.

In contrast, in hypoxia, increased TIS11B expression paralleled an increased TIS11B mRNA stability in VHL-overexpressing 786-O cells.

This VHL-mediated TIS11B up-regulation in hypoxia may be important for TIS11B-regulated gene expression: we observed a down-regulation of VEGF mRNA in hypoxia in VHL-overexpressing cells compared with parental 786-O cells, and this effect was reversible by silencing TIS11B expression.

[Title] Chromophobe renal cell carcinoma with sarcomatoid transformation in a dog.

An abdominal ultrasonographic examination revealed a left renal tumor measuring 8 cm in diameter, and a nephrectomy was performed.

The resected kidney contained a cavitated tumor with a white solid region.

Histologically, this tumor was composed of large polygonal cells with abundant and cloudy cytoplasm and focal sarcomatoid change.

The neoplastic epithelial cells were reactive with colloidal iron staining; Dolichos biflorus agglutinin, peanut agglutinin, and Ulex europaeus agglutinin I lectins; and cluster of differentiation 10 and c-KIT antigens but not for periodic acid-Schiff or vimentin stain.

Neoplastic sarcomatoid cells stained positive for vimentin.

Because these histopathologic features are identical to those of human chromophobe renal cell carcinoma, the present case was diagnosed as canine chromophobe renal cell carcinoma.

[Title] Transcriptional program associated with IFN-alpha response of renal cell carcinoma.

Metastatic renal cell carcinoma (RCC) is refractory to therapy; however, 10%-20% of patients respond favorably with interferon-alpha (IFN-alpha) treatment.

To understand the molecular basis of response to IFN-alpha therapy, we performed global gene expression analysis of sensitive and resistant RCC cell lines in the absence and in the presence of IFN-alpha, using high-density oligonucleotide arrays to detect differentially expressed genes.

In the absence of IFN-alpha, no significant differences in gene expression were observed between six sensitive and six resistant cell lines.

Gene expression analysis following a time course of IFN-alpha2b treatment in one sensitive (SK-RC-17) and one resistant (SK-RC-12) cell line revealed that 484 and 354 transcripts, respectively, were modulated.

A considerable number of these transcripts were similarly modulated between the two cell types that included several known targets of IFN signaling associated with antiviral and immunomodulatory activity.

A further analysis of gene expression pattern in response to IFN revealed that several transcripts associated with proapoptotic function were upregulated in the sensitive cells.

In the resistant cells, transcripts associated with cell survival and proliferation were induced, and key apoptotic molecules were suppressed.

This study suggests that the IFN-alpha response of individual RCC tumors is determined by the expression pattern of genes in the apoptosis vs. survival and proliferation pathways rather than by alterations in expression of one or more individual genes.

[Title] Nephron-sparing surgery for de novo renal cell carcinoma in allograft kidneys.

Renal cell carcinomas account for 4.6% of post-transplant cancers, 10% of which occur in allograft kidneys.

We report three such cases among kidney grafts that were performed or followed from 1970 to 2004.

In all patients, we performed a partial allograft nephrectomy after consideration of the tumor size, location, and absence of metastases and local extension.

Renal function has remained stable, and there has been no sign of graft rejection, tumor recurrence or metastases.

The lateral, peripherally located tumor allowed excision without renal hilar dissection or entry into the collecting system.

In agreement with data emerging from the literature, the present cases confirm that even in the setting of long-standing immunosuppression, de novo RCC of the kidney graft warrants a minimally invasive approach to spare patients graft loss and return to hemodialysis.

[Title] A prospective study of body mass index, hypertension, and smoking and the risk of renal cell carcinoma (United States).

OBJECTIVE: We prospectively investigated the independent association of hypertension, thiazide use, body mass index, weight change, and smoking with the risk of renal cell carcinoma among men and women using biennial mailed questionnaires.

RESULTS: During 24 years of follow-up for women and 12 years for men, 155 and 110 incident cases of renal cell carcinoma were confirmed, respectively.

After adjusting for age, updated BMI and smoking, an updated diagnosis of hypertension was associated with renal cell carcinoma (RCC); the relative risk (RR) was 1.9 (95% CI 1.4-2.7) for women and 1.8 (95% CI 1.2-2.7) for men.

Based on limited data regarding the use of thiazide diuretics, we did not observe a risk associated with their use, independent of the diagnosis of hypertension.

CONCLUSIONS: Diagnosis of hypertension, higher BMI, and increasing pack-years of smoking appear to independently increase the risk of renal cell carcinoma.

[Title] Characterization and gene expression analysis of novel matched primary and metastatic renal cell carcinoma cell lines.

Despite recent advances in molecular biology that have clarified the mechanisms involved in the metastasis of several types of cancer, the molecular mechanism underlying the metastasis of renal cell carcinoma (RCC) remains unclear.

Two RCC cell lines were successfully established from the surgical specimens of a matched primary tumor and adrenal metastasis from the same RCC patient, and were designated as TMK-1P and TMK-1M, respectively.

DNA microarray analysis showed a large differential expression of genes related to cell adhesion and the extracellular matrix molecules of which hexabrachion (tenascin-C), epidermal growth factor receptor, cadherin-6, and beta1-catenin were down-regulated, and the 67 kDa laminin receptor 1 and transforming growth factor-beta-induced 68 kDa protein (betaig-h3) were up-regulated in TMK-1M.

Real-time RT-PCR analysis confirmed this differential gene expression between the two cell lines.

The RCC cell lines may be useful in studying tumor invasion and screening markers for metastasis.

[Title] Renal cell carcinoma presenting with paraneoplastic hypercalcemic coma: a case report and review of the literature.

We report a case of a 62-year-old woman with renal cell carcinoma (RCC) presenting with a hypercalcemia-induced coma.

Initial imaging was negative, but PET scan identified a mass in the upper pole of the left kidney.

Our patient underwent partial nephrectomy, and the mass was identified as RCC on final pathology.

This case report describes a patient with RCC with the unusual presentation of hypercalcemic coma.

We review the differential diagnosis of malignant hypercalcemia and the evaluation of hypercalcemia occurring with RCC.

[Title] Comparison of laparoscopic and open partial nephrectomies in t1a renal cell carcinoma: a korean multicenter experience.

PURPOSE: We analyzed a series of patients who had undergone laparoscopic partial nephrectomies (LPNs) and open partial nephrectomies (OPNs) to compare outcomes of the two procedures in patients with pathologic T1a renal cell carcinomas (RCCs).

MATERIALS AND METHODS: From January 1998 to May 2009, 417 LPNs and 345 OPNs were performed on patients with small renal tumors in 15 institutions in Korea.

Of the patients, 273 and 279 patients, respectively, were confirmed to have pT1a RCC.

Although the tumor location was more exophytic (51% vs. 44%, p=0.047) and smaller (2.1 cm vs. 2.3 cm, p=0.026) in the LPN cohort, the OPN cohort demonstrated shorter ischemia times (23.4 min vs. 33.3 min, p<0.001).

The LPN may be an acceptable surgical option in patients with small RCC in Korea.

[Title] Clear cell hidradenoma: a mimic of metastatic clear cell tumors.

Clear cell hidradenoma is a benign skin appendage tumor that may mimic conventional-type renal cell carcinoma.

Histologically, clear cell hidradenoma contains small ductular lumens, focal apocrine and squamoid change, and a less prominent vascular pattern than renal cell carcinoma.

Furthermore, immunohistochemical studies can aid in distinguishing the 2 tumors.

Detailed clinical history, physical findings, and ancillary studies are essential for correct diagnosis and categorization of these tumors.

We report the rare case of a patient with renal cell carcinoma who underwent excision of an axillary clear cell hidradenoma, which was clinically suggestive of cutaneous metastatic disease.

[Title] The prognostic value of the width of the surgical margin in the enucleoresection of small renal cell carcinoma: an intermediate-term follow-up.

OBJECTIVES: To assess the prognostic value of the width of a healthy surgical margin in the enucleoresection of small renal cell carcinoma, in which 68% of cases had a margin width of 3.0 mm or less.

METHODS: We retrospectively reviewed 98 consecutive enucleoresections regarding the width of healthy margin and tumor recurrence in 96 patients followed up for more than 3 years after surgery.

RESULTS: The mean tumor size was 2.8 cm (range, 1.0-6.1).

Only 1 patient developed tumor recurrence during follow-up, excluding a patient with von Hippel Lindau disease.

CONCLUSIONS: The width of the surgical margin was not associated with the oncological prognosis in our enucleoresection series of small renal cell carcinoma, in which the width of the margin was 3.0 mm or less in more than two-thirds of the cases.

[Title] Bilateral renal-cell carcinoma associated with an acquired VHL mutation and long-term trichloroethylene exposure.

BACKGROUND/AIMS: The genetic basis for clear-cell renal carcinomas has been established in familial and many sporadic forms.

METHODS: PCR amplification and sequencing of VHL exons 1 - 3 were performed on peripheral blood and tumor tissue.

RESULTS: The tumor alone had a previously undescribed mutation in exon 1 of the VHL gene: deletion of a cytidine residue at position 291 relative to the first ATG start codon of the wild-type sequence.

There is loss of suppressor function when substrates such as hypoxia-inducible factor have impaired degradation: they accumulate and ultimately cause uncontrolled cell turnover.

This association of a proposed occupational cause and occurrence of renal-cell carcinoma emphasizes the availability and use of VHL sequencing for both studying the pathophysiology of malignant transformation and potentially playing a clinical role in genetic counseling or risk assessment.

[Title] Significance of B7-H1 overexpression in kidney cancer.

B7-H1 is a cell surface glycoprotein belonging to the B7 family of costimulatory molecules.

Constitutive protein expression is restricted to a fraction of macrophage-lineage cells, although B7-H1 can be induced on activated T lymphocytes.

In addition, some human tumor cells can acquire the ability to aberrantly express B7-H1.

In vitro studies demonstrate that B7-H1, expressed by tumor cells or activated lymphocytes, impairs T-cell function and survival and enhances apoptosis of activated tumor-specific T cells.

Consistent with this, in vivo monoclonal antibody blockade of B7-H1 has been shown to potentiate antitumor responses in several murine cancer models.

Thus, tumor-associated B7-H1 has recently garnered much attention as a potential inhibitor of host antitumor immunity.

We describe herein the published investigations looking at the role of B7-H1 in renal cell carcinoma (RCC).

Clinical observations demonstrate that B7-H1 is aberrantly expressed in primary and metastatic RCC.

All patients had clear-cell RCC, and pathologic evaluation was performed by a single urologic pathologist.

Their results demonstrated that B7-H1, expressed by tumor cells or lymphocytes, is associated with aggressive pathologic features, including TNM stage, nuclear grade, tumor size, and coagulative necrosis.

With a median clinical follow-up of 11 years, patients with tumor B7-H1 were at significant risk of disease progression, cancer-specific death, and overall mortality even after multivariate analyses.

Five-year cancer-specific survival rates were 42% and 83% for patients with and without tumor B7-H1, respectively.

The basis for these associations could relate to the recognized ability of B7-H1 to inhibit antitumor T-cell-mediated immunity.

Based on the current literature, B7-H1 is an independent predictor of prognosis in RCC and represents a promising target for immune manipulation in this refractory tumor.

We demonstrate that ZONAB/DbpA and symplekin form a complex in kidney and intestinal epithelial cells that can be immunoprecipitated and that exists in the nucleus.

RNAi experiments indicate that symplekin depletion reduces the nuclear accumulation and the transcriptional activity of ZONAB/DbpA in colon adenocarcinoma cells, resulting in inhibition of proliferation and reduced expression of the ZONAB/DbpA-target gene cyclin D1.

[Title] Proposal for revision of the TNM classification system for renal cell carcinoma.

BACKGROUND: The current study defined an optimal tumor size breakpoint to stratify localized renal cell carcinoma (RCC) into groups with significantly different cancer-related outcomes and proposed a revision of the TNM classification system.

METHODS: The authors analyzed the data from 1138 patients who had undergone partial or radical nephrectomy for localized RCC at 7 European urologic centers.

The scatterplot of tumor size versus expected risk of death per patient suggested that an interval of 5-6 cm was appropriate.

A total of 720 (63.3%) and 418 (36.7%) patients had tumors measuring < or = 5.5-cm and tumors measuring > 5.5-cm, respectively.

Significant cancer-specific survival differences between the two groups of patients were reported in the series by all the centers participating in the study.

On univariate analysis, the other variables found to be associated with cancer-specific survival were the patient's age, symptomatic tumor presentation, and the Fuhrman nuclear grade.

On multivariate analysis, the pathologic stage of the primary tumor defined according to the 5.5-cm breakpoint was found to be an independent predictor of cancer-specific survival, as well as age, mode of presentation, and nuclear grade.

1) patients with < or = 5.5-cm incidentally detected RCC;.

2) patients with < or = 5.5-cm symptomatic RCC; and 3) patients with > 5.5-cm RCC.

This cancer-related outcome stratification was valid regardless of the patient's age.

CONCLUSIONS: The 5.5-cm breakpoint was found to be the optimal tumor size breakpoint with which to stratify patients with organ-confined RCC.

The study supported the upgrade of the TNM classification system according to this breakpoint.
