    Renal dysfunction is encountered in 20-25% of patients with multiple myeloma (MM) at the time of diagnosis. There is often a precipitating event. Several biochemical and clinical correlations with renal failure in MM have been reported. Renal failure in MM is associated with worse outcome of the disease. We retrospectively analyzed the medical records of 64 patients with MM admitted to our institution during the period January 1992 to December 2012. Abnormal renal function was observed in 24 (37.5%) patients and 17 (26.6%) of them had renal failure; 14 of the 17 (82.4%) of patients with renal failure had Stage III MM. Urine Bence- Jones protein was positive in ten (58.8%) patients with renal failure versus ten (21.3%) patients without renal failure (P = 0.004). Potential precipitating factors of renal failure were determined in nine patients. Renal function normalized in 11 patients with simple measures, while six patients required hemodialysis; one remained dialysis dependent till time of death. Early mortality occurred in five (29.4%) patients with renal failure as compared with two (4.3%) patients in the group without renal failure (P = 0.005). In conclusion, renal failure is associated with a higher tumor burden and Bence-Jones proteinuria in patients with MM. It is reversible in the majority of patients; however, early mortality tends to be higher in patients with persistent renal failure.

    Myeloma is a challenging blood cancer characterized by bone destruction, hypercalcaemia, renal insufficiency and anaemia. Although myeloma remains incurable, recent advancements in treatments have resulted in significant improvements in morbidity. The use of immunomodulatory drugs-thalidomide, lenalidomide, pomalidomide (in clinical trials)-and the proteasome inhibitor, bortezomib, in conjunction with conventional chemotherapy and supportive therapies, have resulted in a significant shift in approaches to treatment and an improvement in patients\\' quality of life. Nurses must remain up-to-date with current treatments for myeloma and their related side-effects. In addition, nurses play a key role in the coordination of a multidisciplinary approach to care for myeloma patients.

    The coexistence of two malignancies is rarely seen. A little association between hematologic malignancies especially multiple myeloma and renal cell carcinoma has been reported in the recent past. Several case series revealed a bidirectional association between these two malignancies which may be due to the common risk factors, similar cytokine growth requirements and clinical presentation. Here, we aim to describe a patient who had multiple myeloma and in his work up renal cell carcinoma was found out incidentally. We would like to create awareness among clinicians for the coincidence of Renal cell carcinoma and Multiple myeloma.

    Kidney dysfunction is a common clinical feature of symptomatic multiple myeloma. Some degree of renal insufficiency or renal failure is present at diagnosis or will occur during the course of the disease and, if not reversed, will adversely affect overall survival and quality of life. Chronic insults to the kidneys from other illnesses, treatment, or multiple myeloma itself can further damage renal function and increase the risk for additional complications, such as anemia. Patients with multiple myeloma who have light chain (Bence Jones protein) proteinuria may experience renal failure or progress to end-stage renal disease (ESRD) and require dialysis because of light chain cast nephropathy. Kidney failure in patients with presumed multiple myeloma also may result from amyloidosis, light chain deposition disease, or acute tubular necrosis caused by nephrotoxic agents; therefore, identification of patients at risk for kidney damage is essential. The International Myeloma Foundation's Nurse Leadership Board has developed practice recommendations for screening renal function, identifying positive and negative contributing risk and environmental factors, selecting appropriate therapies and supportive care measures to decrease progression to ESRD, and enacting dialysis to reduce and manage renal complications in patients with multiple myeloma.

    Multiple myeloma (MM) remains incurable despite much progress that has been made in the treatment of the disease. MM cancer stem cell (MMSC), a rare subpopulation of MM cells with the capacity for self-renewal and drug resistance, is considered to lead to disease relapse. Several markers such as side population (SP) and ALDH1+ have been used to identify MMSCs. However, ideally and more precisely, the identification of the MMSCs should rely on MMSCs phenotype. Unfortunately the MMSC phenotype has not been properly defined yet. Drug resistance is the most important property of MMSCs and contributes to disease relapse, but the mechanisms of drug resistance have not been fully understood. The major signaling pathways involved in the regulation of self-renewal and differentiation of MMSCs include Hedgehog (Hh), Wingless (Wnt), Notch and PI3K/Akt/mTOR. However, the precise role of these signaling pathways needs to be clarified. It has been reported that the microRNA profile of MMSCs is remarkably different than that of non-MMSCs. Therefore, the search for targeting MMSCs has also been focused on microRNAs. Complex and mutual interactions between the MMSC and the surrounding bone marrow (BM) microenvironment sustain self-renewal and survival of MMSC. However, the required molecules for the interaction of the MMSC and the surrounding BM microenvironment need to be further identified. In this review, we summarize the current state of knowledge of MMSCs regarding their phenotype, mechanisms of drug resistance, signaling pathways that regulate MMSCs self-renewal and differentiation, abnormal microRNAs expression, and their interactions with the BM microenvironment.

    Full Text Available Multiple Myeloma (MM frequently presents with renal dysfunction apart from other manifestations. Development of renal failure in patients with MM carries a poor prognosis. Bortezo-mib is a new addition to drugs used in MM and has shown good efficacy and safety profiles. Previous trials have shown its efficacy in relapsed and refractory MM as well. Studies have also shown that bortezomib is also effective in patients with MM who present with renal failure. We report here six cases of renal failure secondary to MM treated with bortezomib. All patients had poor performance status of 3-4 on ECOG scale. Five out of six patients showed satisfactory anti-myeloma response to bortezomib. Reversal of renal failure was observed in all six patients. Adverse effects to bortezomib were mild and manageable. Reversal of renal failure persisted despite incomplete response to MM in two cases, and progression of disease in one patient. It appears that bortezomib may have an effect on the kidneys in reversal of renal failure, other than its anti-myeloma effect. In conclusion, borte-zomib appears to be an effective treatment for patients with advanced MM and renal failure irres-pective of performance status and age.

A 45-year-old man on hemodialysis for six months for end-stage kidney disease due to presumed chronic glomerulonephritis developed immediate graft dysfunction post-transplantation. The graft biopsy was diagnostic of myeloma cast nephropathy. Other criteria for lambda light chain multiple myeloma were fulfilled with immunofixation electrophoresis and bone marrow biopsy. He was treated with plasmapheresis, bortezomib and high-dose dexamethasone. However, the patient succumbed to septicemia on the 37 th post-operative day. This is probably the first report of primary renal allograft dysfunction due to myeloma cast nephropathy diagnosed within the first week posttransplanation in a patient with unrecognized multiple myeloma.

    Full Text Available A insuficiência renal (IR é uma complicação freqüente em pacientes com mieloma múltiplo (MM podendo estar presente em 35% dos pacientes ao diagnóstico e em mais de 50% durante a evolução da doença. O mecanismo mais freqüente de IR é o assim chamado "rim do mieloma" decorrente da excreção de cadeias leves provocando um dano tubular. Outros mecanismos de IR são o depósito tissular de cadeias leves e a Síndrome de Fanconi Adquirida. Determinados fatores podem precipitar e agravar a IR tais como a hipercalcemia, hiperuricemia, desidratação, hiperviscosidade e drogas nefrotóxicas. O tratamento de suporte deve ser feito em todos os pacientes e nos casos em que a função renal não possa ser revertida deve ser considerado o tratamento dialítico. O tratamento específico do MM em pacientes com IR tem papel importante e impacto na sobrevida. A quimioterapia inicial mais adequada é VAD ou combinação de ciclofosfamida e dexametasona. Quimioterapia em altas doses e transplante autólogo podem ser considerados para pacientes com idade inferior a 60 anos e um bom performance status (PS.Renal insufficiency is a frequent complication in patients with Multiple Myeloma (MM. It occurs in 35% of newly diagnosed patients and in more than 50% during the evolution of the disease. The most frequent mechanism of renal failure is the so-called "myeloma kidney", which is the renal tubular damage caused by the excretion of light chains. Other mechanisms of renal damage are light chain tissue deposition and acquired Fanconi's syndrome. This renal impairment might be aggravated by precipitating factors such as hypercalcemia, hyperuricemia, dehydration, hyperviscosity, and nephrotoxic drugs. Supportive measures must be taken for all patients; for those with an irreversible renal function, dialysis must be considered. Specific myeloma treatment has an important prognostic value for patients with renal impairment. The recommendation of induction

    Sunitinib is a multiple tyrosine kinase receptors inhibitor that is approved for the treatment of advanced renal cell carcinoma. Amongst its targets are fetal liver tyrosine kinase receptor 3 (FLT 3) and vascular endothelial growth factor receptor (VEGFR). Renal toxicity has not been reported from the trials, but several patients have been reported to develop a pre-eclampsia-like syndrome. We report the first case of acute tubular necrosis in a patient with multiple myeloma following treatment with sunitinib.

    Renal failure is a frequent complication of multiple myeloma (MM). Recently, the combination of lenalidomide-dexamethasone has become one of the cornerstone regimens for the treatment of MM. Impairment of renal function exacerbation is a rare, but potential, complication of lenalidomide therapy in plasma cell dyscrasias. We present two patients who developed exacerbation of renal function during their first cycle of therapy with lenalidomide. In the first case, we present a 76-year-old-male with MM and impaired renal function, who declined two weeks after initiation of second-line therapy with lenalidomide. His renal functions improved after discontinuation of lenalidomide and with supportive care. In the second case, we describe a 61-year-old woman who was started on lenalidomide for relapsed MM and admitted to intensive care unit three weeks later due to severe renal failure. Despite intensive supportive care, her renal function deteriorated even more and she died. We conclude that renal failure is an uncommon, but serious, potential complication of lenalidomide therapy in plasma cell dyscrasias, particularly MM. Close monitoring of renal function is clearly recommended during this treatment.

    2017-09-01

    Full Text Available The article describes a clinical case of multiple myeloma in 78-year-old man, its clinical onset was as an acute attack of gout. The patient was admitted to hospital due to the development of the first acute attack of gout. The attack was characterized by polyarthricular joint lesion of the upper and lower extremities, pronounced inflammatory reaction, insufficient response to the use of non-steroidal anti-inflammatory drugs, and a high level of hyperuricemia. The serum uric acid concentration ranged from 636 to 712 μmol/l. The study of the synovial fluid of the inflamed knee joint made it possible to reveal uric acid crystals and to confirm the diagnosis of acute gouty arthritis. Simultaneously, the patient had significant renal impairment: creatinine was 574 μmol/l, urea — 39.9 mmol/l, glomerular filtration rate according to CKD-EPI — 8 ml/min. The daily proteinuria was 1.8 g. A retrospective assessment of laboratory parameters allowed to reveal completely normal indicators of renal function 6 months ago. Considering the development of acute gouty arthritis, its polyarticular nature, persistent course, rapid involvement of new joints, high uric acid levels during an acute attack exceeding 600 μmol/l (10 mg/dL, rapid development of renal failure within 6 months until the terminal stage, it was suggested the secondary nature of gout on the background of kidney damage by another pathological process. Further clinical, laboratory and instrumental studies allowed verifying multiple myeloma with renal damage. Bence Jones protein in the urine was not detected, there was also no evidence of hyperproteinemia. However, pain in the spine, ribs and chest was the basis for carrying out an X-ray study of the bones of the skeleton. Changes in the skeleton typical for multiple myeloma have been identified. Myelogram showed a high content of plasma cells (21.1 %, electrophoresis of blood proteins showed a high M-gradient (30.42 %, and a cytochemical

    Renal cell carcinoma (RCC) is a common form of urologic tumor that originates from the highly heterogeneous epithelium of renal tubules. Over the last decade, targeting therapies to renal cancer cells have transformed clinical care for RCC. Recently, it was proposed that renal cancer stem cells (CSCs) isolated from renal carcinomas were responsible for driving tumor growth and resistance to conventional chemotherapy and radiotherapy, according to the theory of CSCs; this has provided the rati...

    The increase of the aging population corresponds with the rise of renal cancer in elderly patients. The distinction between functional and chronological age, quality of life, and survival estimate are important issues, among others, that should be considered in the management of renal cancer in elderly patients. We made this review with the purpose of synthesizing the most updated criteria regarding indications and outcomes of the different therapeutic options in the management of elderly patients with renal cancer, beginning from the physiologic considerations that characterize them, their capacity to tolerate different therapeutic possibilities, and the prognosis of the patients' risks and comorbidity assessment.

    Objective: The aim of the study was to investigate the clinic manifestation, diagnosis and treatment on multiple myeloma (MM) with the onset of renal impairment. Methods: The 27 cases of multiple myeloma with the onset of renal impairment were collected in Department of Nephrology, Wuhan General Hospital of Guangzhou Command, China, from January 2007 to January 2011. All cases were divided into the groups with renal dysfunction (n = 16) and normal renal function (n =11). The clinic manifestations, treatments and prognosis of all patients were analyzed. Results: Of all the patients in normal renal function group, 5 suffered nephrotic syndrome, 4 had abnormal results of routine urinalysis (hematuria or proteinuria)which were not caused by nephrotic syndrome, and 1 suffered urinary tract infection. Five pathological specimens of renal biopsy revealed that light chain protein, immunoglobulin and complement C3 were deposited mainly in the glomerular basement membrane and mesangia, tubular basement membrane and arteriolar walls. Two pathological specimens were proved to be renal amyloidosis. Patients with renal dysfunction had poorer prognosis, severer anemia, higher values of serum lactate dehydrogenase (LDH) and β2-microglobulin (β2-MG), worse responses to chemotherapy. Of 16 patients with renal dysfunction, 14 (87.5%) were stage III, which were significantly higher than that in the group of normal renal function [63.6% (7/11)]. Of 16 cases with renal dysfunction, 9 were treated with blood purification, and 5 of 9 cases were treated with plasma exchange.Conclusion: Multiple myeloma with the onset of renal impairment was easily misdiagnosed. Hemodialysis concomitant with chemotherapy could contribute to recovery of renal function.

    Multiple myeloma (MM) is a haematological tumour that is characterised by uncontrolled proliferation of plasma cells and a significant volume of serum free light chains (sFLCs), which can cause acute renal failure due to intratubular precipitation, resulting in cast nephropathy. Acute renal failure is a complication that can arise in more than 20% of patients with multiple myeloma, half of which will require dialysis. We report our experience with 13 patients who were treated with dialysis using high cut off filters (HCO) between July 2011 and February 2015. A total of 6 consecutive 6-hour sessions were performed using a 2.1 m(2) HCO filter (Theralite® by Gambro®). Afterwards, further 6-hour sessions were continued on alternate days. A total of 151 sessions were conducted, with an average of 11.6 sessions per patient (range 6-27). The treatment proved to be effective in removing both kappa and lambda sFLCs, resulting in a 93.7% fall in sFLCs by the end of treatment. The average reduction was 57.7% per dialysis session. 10 out of the 13 cases recovered sufficient renal function to become independent of dialysis. There were no major changes in albumin levels using an infusion protocol of 2 50-mL vials of 20% albumin at the end of the dialysis session. Combination treatment with chemotherapy and long dialysis with HCO filters was effective in reducing the sFLC levels and recovering sufficient renal function in 77% of cases. With HCO filters, significant cost savings are achieved, contrary to what was previously believed. Copyright © 2016 Sociedad Española de Nefrología. Published by Elsevier España, S.L.U.

    Multiple myeloma accounts for 1.6% of all cancer cases and approximately 10% of hematologic malignancies in the United States. In 2015, an estimated 28,850 new cases of multiple myeloma were diagnosed in the United States, and the disease caused more than 11,000 deaths. Patients older than 65 years account for 85% of those diagnosed with multiple myeloma, and there is a twofold increased incidence in blacks compared with whites. Patients may present with bone pain or with symptoms that are often nonspecific, such as nausea, vomiting, malaise, weakness, recurrent infections, and weight loss. Many patients present with only laboratory abnormalities, such as anemia, renal disease, and elevated protein levels. The diagnosis of multiple myeloma requires increased numbers of immature, abnormal, or atypical plasma cells in the bone marrow; a monoclonal protein in the serum or urine; or characteristic bone lesions. The diagnostic workup in a patient with suspected multiple myeloma should include a complete blood count with differential; serum chemistries; creatinine, lactate dehydrogenase, and beta2-microglobulin tests; immunoglobulin studies; skeletal survey; and bone marrow evaluation. Initiation of chemotherapy and assessment of eligibility for autologous stem cell transplantation require referral to an oncologist. Most patients with multiple myeloma will receive thromboprophylaxis, bisphosphonate therapy, and prophylaxis against infection at some point in their treatment. Family physicians play a role in assessing these patients for infection, adverse treatment effects, and renal and thrombotic complications, and in managing issues related to pain, nutrition, and psychosocial support.

    Background Light chain amyloidosis (AL) is a rare deposition disease and is present in 10–15% of patients with myeloma (MM). In contrast to symptomatic AL in MM, presence of bone marrow (BM) amyloid deposits (AD) in MM is not connected to kidney damage. Renal AD but not BM-AD occur mostly in MM with lambda paraprotein (lambda MM). Methods We investigated amyloid presence in BM clots taken at diagnosis in 84 patients with symptomatic MM and compared disease characteristics in MM with kappa paraprotein (kappa MM)/lambda MM with and without BM-AD. Results Lambda MM with BM-AD was compared with kappa MM without BM-AD, kappa MM with BM-AD, and lambda MM without BM-AD: lambda MM with BM-AD patients had a significantly higher mean creatinine level (4.23 mg/dL vs 1.69, 1.14, and 1.28 mg/dL, respectively) and a higher proportion presented with severe kidney failure (6/11 [55%] vs 6/32 [19%], 1/22 [5%], and 3/19 [16%], respectively). Proteinuria was more common in lambda MM with BM-AD patients compared with kappa MM without BM-AD patients (8/11 [73%] vs 5/32 [16%], respectively). Conclusion Kidney damage was more common in lambda MM with BM-AD indicating presence of renal AD. PMID:28293126

    Renal cell carcinoma (RCC) is a common form of urologic tumor that originates from the highly heterogeneous epithelium of renal tubules. Over the last decade, targeting therapies to renal cancer cells have transformed clinical care for RCC. Recently, it was proposed that renal cancer stem cells (CSCs) isolated from renal carcinomas were responsible for driving tumor growth and resistance to conventional chemotherapy and radiotherapy, according to the theory of CSCs; this has provided the rationale for therapies targeting this aggressive cell population. Precise identification of renal CSC populations and the complete cell hierarchy will accurately inform characterization of disease subtypes. This will ultimately contribute to more personalized and targeted therapies. Here, we summarize potential targeting strategies for renal cancer cells and renal CSCs, including tyrosine kinase inhibitors, mammalian target of rapamycin inhibitors (mTOR), interleukins, CSC marker inhibitors, bone morphogenetic protein-2, antibody drug conjugates, and nanomedicine. In conclusion, targeting therapies for RCC represent new directions for exploration and clinical investigation and they plant a seed of hope for advanced clinical care.

    The goal of this investigation was to evaluate the inhibiting effect of high proportion polyethyleneglycol of long-circulating homoharringtonine liposomes on RPMI8226 multiple myeloma cancer stem cells. The CD138(-)CD34(-) multiple myeloma cancer stem cells isolated from RPMI8226 cell line using magnetic activated cell sorting system were, respectively, incubated with the optimized formulation of polyethyleneglycol of long-circulating homoharringtonine liposomes and the homoharringtonine in vitro, and the multiple myeloma cancer stem cell proliferation, colony formation, and cell cycle were analyzed. The inhibition of the multiple myeloma CD138(-)CD34(-) cancer stem cell growth was investigated in non-obese-diabetic/severe-combined-immunodeficiency mice that were implanted with multiple myeloma RPMI 8226 cancer stem cells and treated with the LCL-HHT-H-PEG. The results showed that the polyethyleneglycol of long-circulating homoharringtonine liposomes significantly inhibited MM cancer stem cell proliferation, colony formation, and induced cancer stem cell apoptosis in vitro as well as MM cancer stem cell growth in non-obese-diabetic/severe-combined-immunodeficiency mice compared with the homoharringtonine. In addition, the mouse bone mineral density and the red blood cell count were significantly increased in polyethyleneglycol of long-circulating homoharringtonine liposomes group. In conclusion, the data demonstrated that the developed polyethyleneglycol of long-circulating homoharringtonine liposomes formulation may serve as an efficient therapeutic drug for suppressing CD138(-)CD34(-) multiple myeloma cancer stem cell growth by inducing cancer stem cell apoptosis in non-obese-diabetic/severe-combined-immunodeficiency mouse model. Impact statement Multiple myeloma (MM) remains largely incurable until now. One of the main reasons is that there are cancer stem cells (CSCs) in MM, which are responsible for MM's drug resistance and relapse. In this study, we wanted

    Multiple myeloma (MM) continues to claim the lives of a majority of patients. MM cancer stem cells (CSCs) have been demonstrated to sustain tumor growth. Due to their ability to self-renew and to express detoxifying enzymes and efflux transporters, MM-CSCs are rendered highly resistant to conventional therapies. Therefore, managing MM-CSCs characteristics could have profound clinical implications. Bruceantin (BCT) is a natural product previously demonstrated to inhibit the growth of MM in RPMI 8226 cells-inoculated mouse xenograft models, and to cause regression in already established tumors. The objectives of the present study were to test the inhibitory effects of BCT on MM-CSCs growth derived from a human primary tumor, and to explore a mechanism of action underlying these effects. BCT exhibited potent antiproliferative activity in MM-CSCs starting at 25 nM. BCT induced cell cycle arrest, cell death and apoptosis in MM-CSCs as well as inhibited cell migration and angiogenesis in vitro. Using a qPCR screen, it was found that the gene expression of a number of Notch pathway members was altered. Pretreatment of MM-CSCs with the γ-secretase inhibitor RO4929097, a Notch pathway inhibitor, reversed BCT-induced effects on MM-CSCs proliferation. In this study, BCT was shown to be an effective agent in controlling the proliferation, viability and migration of MM-CSCs as well as angiogenesis in vitro. The effect on MM-CSCs proliferation may be mediated by the Notch pathway. These results warrant further investigation of BCT in a broader set of human-derived MM-CSCs and with in vivo models representative of MM.

    Full Text Available We report a case of coexisting urothelial cancer and renal tuberculosis in the same kidney. The patient is a 72-year-old female with a remote history of treated pulmonary tuberculosis who presented with haematuria, initial investigation of which elucidated no definitive cause. Almost 1 year later, a diagnosis of metastatic urinary tract cancer was made. The patient received chemotherapy for advanced collecting duct type renal cell carcinoma, based on histological features of renal biopsy. Subsequent confirmatory immunostains however led to a revised diagnosis of urothelial cancer, necessitating a change in chemotherapy regimen. A diagnosis of ipsilateral renal tuberculosis was made based on TB-PCR testing of renal biopsy tissue and anti-TB therapy was coadministered with chemotherapy. The patient died 9 months after diagnosis of metastatic urothelial cancer.

    Renal failure commonly complicates multiple myeloma (MM) and is associated with reduced survival. It is not clear whether auto-SCT results in improved renal function or attainment of independence from dialysis in patients with advanced renal impairment due to MM. We conducted a retrospective cohort study of all patients who underwent auto-SCT for MM complicated by advanced renal failure at our institution over a 10-year period (2000-2010). We aimed to assess the association between auto-SCT and renal outcome in patients with serum creatinine (SCr) over 3 mg/dL, attributable to MM, including those who were dialysis dependent. Thirty patients (2.8% of all auto-SCT patients) met inclusion criteria. Fourteen of 15 patients who were dialysis dependent before auto-SCT remained dialysis dependent in the long term despite hematological response (HR). Of the remaining 15 patients with SCr >3 mg/dL, an improvement in glomerular filtration rate (GFR) from 15 to 19.4 mL/min/1.73 m(2) was noted post auto-SCT (P=0.035); however, neither HR post auto-SCT or pre-existing renal function were independently associated with renal outcome. Auto-SCT was not associated with independence from dialysis in patients with renal failure due to MM at our institution. Although auto-SCT was associated with an improvement in GFR in patients with SCr >3 mg/dL, this improvement was not related to HR.

  4. EARLY APPLICATION OF HIGH CUT-OFF HAEMODYALISIS FOR DE-NOVO MYELOMA NEPHROPATHY IS ASSOCIATED WITH LONG-TERM DIALYSIS-INDEPENDENCY AND RENAL RECOVERY

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Background Multiple myeloma (MM is a haematological malignancy associated with kidney injury resulting from cast nephropathy, which can be caused by monoclonal free light chains (FLC. It has been demonstrated that reduction of FLC can lead to a higher proportion of patients recovering renal function with a better outcome, especially if extended high cut-off haemodialysis (HCO-HD combined with chemotherapy is used. Patients and Methods In this study, four cases of MM nephropathy were treated with HCO-HD and chemotherapy at a single institution during the period from August 2009 to August 2011. All of the patients presented with acute renal failure and high serum FLC. All patients underwent a bone marrow biopsy to confirm the diagnosis of MM, according to the WHO criteria. Three patients had de-novo MM and one patient had relapsed light chain myeloma disease. All patients underwent HCO-HD concomitantly with specific myeloma therapy once the diagnosis or relapse of MM was established. Results After a median follow up of 26 months, (range, 13-36 our data showed that all patients had a significant decrease in serum FLC through HCO-HD, proving the effectiveness of HCO-HD in managing MM. De-novo MM patients restored their renal function and achieved low-level FLC early on the treatment and become dialysis-independent. One patient with relapsed myeloma remained dialysis dependant. Conclusion Our study suggests that if myeloma nephropathy associated with light-chain disease, HCO-HD should be initiated as early as possible. At the same time a specific MM treatment should be initiated to gain control of the disease and salvage the kidneys in order to achieve dialysis-independency. Further trials to confirm our results are warranted. Key Words: Multiple myeloma, renal failure, High cut-off haemodialysis, chemotherapy, outcome.

  5. Lenalidomide is effective and safe for the treatment of patients with relapsed multiple myeloma and very severe renal impairment.

    Patients with multiple myeloma (MM) and severe renal impairment (SRI) have shorter survival than MM patients without renal failure. Although lenalidomide is a highly active drug, this immunomodulatory agent is frequently neglected in this context due to its predominant renal clearance and, consequently, an increased risk of toxicity. This risk might be overcome with the proper lenalidomide dose adjustment to renal function. This study evaluates the outcomes of 23 relapsed MM patients with SRI (baseline creatinine clearance (CrCl) lenalidomide-dexamethasone (LenDex), including 56 % (13 patients) under hemodialysis. The median CrCl at start of LenDex was 19 mL/min; an overall response rate (partial response or better) of 56 % was obtained, with a median follow-up from start of LenDex of 52 months (8-79). The median time until maximal response was 4 months, and in 58 % (7/12), the response was longer than 2 years. Nine percent had renal improvement, but all the 13 patients on hemodialysis remained under treatment. LenDex was interrupted in three cases because of adverse events (infections and cutaneous events); 78 % of the patients were on thromboprophylaxis with aspirin. It is important to notice that, after initial dose adjustment of therapy, there should be a continuous process of dose adjustment, taking into account variations in renal function. Furthermore, lenalidomide dose adjustment should be made according to the individual tolerance, even with stable renal function. LenDex dose adjustment, according to these principles, does not negatively impact response and improves treatment tolerance. It has a clear potential to treat this group of patients and to induce long duration of responses [event-free survival (EFS) 20.5 m and overall survival (OS) 42.6 m].

  6. Pathogenesis of Renal Failure in Multiple Myeloma: Any Role of Contrast Media?

    Full Text Available The spectrum of kidney disease-associated monoclonal immunoglobulin and plasma cell malignancies is remarkably broad and encompasses nearly all nephropathologic entities. Multiple myeloma with kidney impairment at presentation is a medical emergency since the recovery of kidney function is associated with survival benefits. In most cases, kidney impairment may be the first clinical manifestation of malignant plasma cell dyscrasias like multiple myeloma and light chain amyloidosis. Multiple myeloma per se cannot be considered a main risk factor for developing acute kidney injury following intravascular administration of iodinated contrast media. The risk is increased by comorbidities such as chronic kidney disease, diabetes, hypercalcemia, dehydration, and use of nephrotoxic drugs. Before the administration of contrast media, the current recommended laboratory tests for assessing kidney function are serum creatinine measurement and the estimation of glomerular filtration rate by using the CKD-EPI equation. The assessment of Bence Jones proteinuria is unnecessary for evaluating the risk of kidney failure in patients with multiple myeloma, since this test cannot be considered a surrogate biomarker of kidney function.

    The International Staging System (ISS) is the most widely used staging system for patients with multiple myeloma (MM). However, serum β2-microglobulin increases in renal impairment (RI) and there have been concerns that ISS-3 stage may include 'up-staged' MM patients in whom elevated β2-microglobulin reflects the degree of renal dysfunction rather than tumor load. In order to assess the impact of RI on the prognostic value of ISS, we analyzed 1516 patients with symptomatic MM and the degree of RI was classified according to the Kidney Disease Outcomes Quality Initiative-Chronic Kidney Disease (CKD) criteria. Forty-eight percent patients had stages 3-5 CKD while 29% of patients had ISS-1, 38% had ISS-2 and 33% ISS-3. The frequency and severity of RI were more common in ISS-3 patients. RI was associated with inferior survival in univariate but not in multivariate analysis. When analyzed separately, ISS-1 and ISS-2 patients with RI had inferior survival in univariate but not in multivariate analysis. In ISS-3 MM patients, RI had no prognostic impact either in univariate or multivariate analysis. Results were similar, when we analyzed only patients with Bence-Jones >200 mg/day. ISS remains unaffected by the degree of RI, even in patients with ISS-3, which includes most patients with renal dysfunction.

    Immunosuppressed patients are known to have an increased incidence of skin cancer. Patients with multiple myeloma (MM) show impaired immune function. In the past, because of poor survival, the incidence of specific secondary primary malignancies such as skin cancer among these patients was difficult to establish. With more effective MM therapies that have emerged in recent years, these patients are living markedly longer, and therefore, it becomes of increasing importance to determine whether their risk of developing other medical problems such as skin cancer is increased. We performed a retrospective cohort study of 205 myeloma patients and 193 age-, race-, and gender-matched control subjects to assess the incidence of skin cancers among patients with MM and determine the specific types of and risk factors for skin cancer. We found that there is an increased occurrence of skin cancer among patients with MM compared to control subjects (26.8% vs. 16.1% in controls; P = 0.009). Among specific types of skin cancer, the proportion of patients with squamous cell carcinoma (SCC) was higher than controls (P = 0.016). In addition to MM diagnosis, older age and Caucasian ethnicity were predictors of skin cancer of any type. Furthermore, older age was also a predictor of SCC. © 2016 John Wiley & Sons A/S.

    Monoclonal gammopathies (MGs) with renal involvement can lead to ESRD caused by myeloma cast nephropathy (MCN), immunoglobulin light chain amyloidosis (ALA), or light-chain deposition disease (LCDD). Few studies have focused on the prognosis of patients with MG on chronic dialysis. We evaluated the outcomes of patients with MG incident on chronic dialysis in France. All incident patients registered in the Renal Epidemiology and Information Network Registry between 2002 and 2011 with ESRD caused by ALA, LCDD, or MCN were included. Patient's survival, censored for renal transplantation, renal recovery, and loss to follow-up, as well as renal outcomes were analyzed and compared with a control group. Risk factors and causes of death were analyzed. We included 1459 patients, comprising 265 (18%) patients with ALA, 334 (23%) patients with LCDD, and 861 (59%) patients with MCN. Median age was 72 years, and 56% were men. Median follow-up was 13.1 months. Renal recovery was observed in 9.1% of patients and more frequent after 2006. Kidney transplantation was rare in this population (2.3%). Among 1272 patients who remained on dialysis, 67% died. Median survival on dialysis was 18.3 months. Main causes of death were malignancies (34.4%), cardiovascular diseases (18%), infections (13.3%), and cachexia (5.2%). Independent risk factors of death were age (hazard ratio [HR], 1.03 per year increase; 95% confidence interval [95% CI], 1.02 to 1.03), frailty (HR, 1.93; 95% CI, 1.58 to 2.36), congestive heart failure (HR, 1.54; 95% CI, 1.23 to 1.93), and dialysis initiation on a central catheter (HR, 1.40; 95% CI, 1.11 to 1.75). Factors associated with a lower risk of death were year of dialysis initiation (HR, 0.95 per year increase; 95% CI, 0.91 to 0.99) and high BP (HR, 0.80; 95% CI, 0.67 to 0.97). Survival of patients with ALA, LCDD, or MCN on chronic dialysis is poor but has improved over time. Progressive malignancy is the main cause of death in this population. Renal recovery

    Full Text Available Chris CoppinBC Cancer Agency and University of British Columbia, Vancouver, CanadaAbstract: Renal cell cancer has been refractory to drug therapy in the large majority of patients. Targeted agents including sunitinib have been intensively evaluated in renal cell cancer over the past 5 years. Sunitinib is an oral small molecule inhibitor of several targets including multiple tyrosine kinase receptors of the angiogenesis pathway. This review surveys the rationale, development, validation, and clinical use of sunitinib that received conditional approval for use in North America and Europe in 2006. In patients with the clear-cell subtype of renal cell cancer and metastatic disease with good or moderate prognostic factors for survival, sunitinib 50 mg for 4 weeks of a 6-week cycle provides superior surrogate and patient-reported outcomes when compared with interferon-alfa, the previous commonly used first-line drug. Overall survival has not yet shown improvement over interferon and is problematic because of patient crossover from the control arm to sunitinib at disease progression. Toxicity is significant but manageable with experienced monitoring. Sunitinib therapy is an important step forward for this condition. High cost and limited efficacy support the ongoing search for further improved therapy.Keywords: renal cell cancer, targeted therapy, sunitinib

    2016-06-01

    Full Text Available Introduction. Although the incidence of malignancy has increased after solid organ transplantation, data on lung cancer in this group of patients is scarce. The aim of this study was to determine clinical characteristics and outcome of patients who developed lung cancer after renal transplantation. Methods. Among a cohort of 1658 patients who received a transplant at our institution and were followedup between 1973 and 2014, five patients developed lung cancer. We analyzed risk factors, transplantation characteristics, treatment options and survival. Results. Lung cancer was diagnosed in 5 patients (0.3%. Time to diagnosis after the transplant procedure ranged from 26 to 156 months (mean 115 months. All of them had a smoking history. Tumors were classified as IIB (20%, IIIA (40%, and IV (40%. Histological types included adenocarcinoma (80% and there was one case of sarcomatoid carcinoma (20%. One patient had concomitant thyroid papillary carcinoma. Radiotherapy was applied in 2 patients, 2 underwent chemotherapy (erlotinib and combination of carboplatinum and etopozide in one patient each, and 2 died within one month after the diagnosis from disseminated malignant disease. Patients with stage IIIA survived 14 and 24 months after the diagnosis. The patient with sarcomatoid cancer underwent thoracotomy with a complete resection, lost his graft function and died 7 months after the diagnosis. Conclusion. Lung cancer is relatively rare malignancy in renal transplant recipients, but associated with high mortality. Smoking is a significant risk factor, thus smoking cessation should be promoted among renal transplant recipients, as well as regular screening for lung cancer.

    Renal cancer occurs more frequently in renal transplanted patients than in the general population, affecting native kidneys in 90% of cases and the graft in 10 %. In addition to general risk factors, malignancy susceptibility may be influenced by immunosuppressive therapy, the use of calcineurin inhibitors (CNI) as compared with mammalian target of rapamycin inhibitors, and the length of dialysis treatment. Acquired cystic kidney disease may increase the risk for renal cancer after transplantation, while autosomal dominant polycystic kidney disease does not seem to predispose to cancer development. Annual ultrasound evaluation seems appropriate in patients with congenital or acquired cystic disease or even a single cyst in native kidneys, and every 2 years in patients older than 60 years if they were on dialysis for more than 5 years before transplantation. Immunosuppression should be lowered in patients who develop renal cancer, by reduction or withdrawal of CNI. Although more evidence is still needed, it seems reasonable to shift patients from CNI to everolimus or sirolimus if not already treated with one of these drugs, with due caution in subjects with chronic allograft nephropathy.

    The galactomannan (GM) test is a useful method for early diagnosis of invasive aspergillosis. Recently, multiple myeloma has newly been suggested to be related to false-positive results of GM. We performed a case-control study to validate this finding. Electronic medical records were reviewed for patients admitted March through June 2014. Patients with false-positive GM results were selected as cases and those with negatives as controls. To verify the results of the four-month analysis, additional analysis was performed in multiple myeloma patients over a three-year period. There were 30 false-positive and 316 negative cases during the four-month period. Among the factors evaluated, multiple myeloma was the only significant factor in the adjusted analysis (OR = 3.59, CI 1.28-10.04). In the three-year analysis of 145 multiple myeloma patients, 25.5% showed false-positive results, which was 3 times higher than overall. GM false-positivity was not related to serum monoclonal protein level or type of immunoglobulin. GM optical density indexes (ODIs) in all false positives were lower than 3.0. Multiple myeloma was a major cause of GM false-positivity in adult cancer patients. GM was false-positive in 25.5% of multiple myeloma patients with GM ODIs lower than 3.0.

    The pharmacokinetics (PK) of carfilzomib have been previously studied in multiple myeloma patients with varying degrees of renal impairment (normal, mild, moderate, severe, and end-stage renal disease [ESRD]) at doses of 15 and 20 mg/m(2). This study evaluated carfilzomib PK at higher doses of 27 and 56 mg/m(2) in normal renal function and ESRD patients. Patients received carfilzomib on two consecutive days/week for 3 weeks every 28-day cycle: 20 mg/m(2) (cycle 1 day 1-2), escalated to 27 mg/m(2) on cycle 1 day 8; if tolerated, 56 mg/m(2) starting cycle 2 day 1. The primary objective was PK assessment with safety/tolerability and response rate as secondary and exploratory objectives, respectively. 26 patients were enrolled (15 normal, 11 ESRD). There was a trend toward higher area under the concentration time curve (AUC) and maximum concentration in ESRD versus normal renal function patients; however, high interpatient PK variability was discerned. Relative to patients with normal renal function, ESRD patients showed 33% higher AUC. Overall response rate was 43% for the normal renal function and 60% for the ESRD groups. Safety findings were generally similar between the two groups and consistent with the known safety profile of carfilzomib in multiple myeloma patients. There were no meaningful differences in PK between patients with normal renal function and ESRD in light of carfilzomib exposure-response relationships. These results continue to support dosing recommendation that no starting dose adjustment of carfilzomib appears warranted in patients with baseline renal impairment.

    2012-01-01

    Full Text Available Cancer/Testis Antigens (CTAs are a promising class of tumor antigens that have a limited expression in somatic tissues (testis, ovary, fetal, and placental cells. Aberrant expression of CTAs in cancer cells may lead to abnormal chromosome segregation and aneuploidy. CTAs are regulated by epigenetic mechanisms (DNA methylation and acetylation of histones and are attractive targets for immunotherapy in cancer because the gonads are immune privileged organs and anti-CTA immune response can be tumor-specific. Multiple myeloma (MM is an incurable hematological malignancy, and several CTAs have been detected in many MM cell lines and patients. Among CTAs expressed in MM we must highlight the MAGE-C1/CT7 located on the X chromosome and expressed specificity in the malignant plasma cells. MAGE-C1/CT7 seems to be related to disease progression and functional studies suggests that this CTA might play a role in cell cycle and mainly in survival of malignant plasma cells, protecting myeloma cells against spontaneous as well as drug-induced apoptosis.

    The p53 pathway is inactivated in the majority of human cancers. Although this perturbation frequently occurs through the mutation or deletion of p53 itself, there are other mechanisms that can attenuate the pathway and contribute to tumorigenesis. For example, overexpression of important p53 negative regulators, such as murine double minute 2 (MDM2) or murine double minute 4 (MDM4), epigenetic deregulation, or even alterations in TP53 mRNA splicing. In this work, we will review the different mechanisms of p53 pathway inhibition in cancer with special focus on multiple myeloma (MM), the second most common hematological malignancy, with low incidence of p53 mutations/deletions but growing evidence of indirect p53 pathway deregulation. Translational implications for MM and cancer prognosis and treatment are also reviewed.

    Renal failure (RF) is a common and severe complication of symptomatic myeloma, associated with significant morbidity and mortality. Such patients are commonly excluded from clinical trials. Bortezomib/dexamethasone (VD)-based regimens are the backbone of the treatment of newly diagnosed MM patients who present with severe RF even those requiring dialysis. We analyzed the outcomes of 83 consecutive bortezomib-treated patients with severe RF (eGFR dialysis. By IMWG renal response criteria, 54 (65%) patients achieved at least MRrenal, including CRrenal in 35% and PRrenal in 12%. Triplet combinations (i.e., VD plus a third agent) versus VD alone were associated with higher rates of renal responses (72 vs. 50%; P = 0.06). Fifteen of the 31 (48%) patients became dialysis independent within a median of 217 days (range 11-724). Triplets were associated with a higher probability of dialysis discontinuation (57 vs. 35%). Serum free light chain (sFLC) level ≥11,550 mg/L was associated with lower rates of major renal response, longer time to major renal response, lower probability, and longer time to dialysis discontinuation. Rapid myeloma response (≥PR within the first month) was also associated with higher rates of renal response. Patients who became dialysis-independent had longer survival than those remaining on dialysis. In conclusion, VD-based triplets are associated with a significant probability of renal response and dialysis discontinuation, improving the survival of patients who became dialysis independent. Rapid disease response is important for renal recovery and sFLCs are predictive of the probability and of the time required for renal response.

    Full Text Available Computational tools and methods play a vital role in handling and analyzing a large volume of genomic data. In cancer research, in silico methods such as computational algorithm and protein databases are indispensable. In this paper, we adopted an in silico approach to analyze oncogenes that cause  renal cancer. Our objective is to identify and analyze the genes which are over expressed in the renal cancer tissues. The identification of oncogenes for renal cancer could provide directions and insights for molecular cancer treatment.

    Renal transplantation is a standard procedure for end-stage renal disease today. Due to immunosuppressive drugs and increasing survival time after renal trans-plantation, patients with transplanted kidneys carry an increased risk of developing malignant tumors. In this case report, 3 patients with advanced rectal can-cer after renal transplantation for renal failure were treated with anterior resection or abdominoperineal resection plus total mesorectal excision, followed by adjuvant chemotherapy. One patient eventually died of metastasized cancer 31 mo after therapy, although his organ grafts functioned well until his death. The other 2 patients were well during the 8 and 21 mo follow-up periods after rectal resection. We therefore strongly argue that patients with advanced rectal cancer should receive standard oncology treatment, including opera-tion and adjuvant treatment after renal transplantation. Colorectal cancer screening in such patients appears justified.

    Since the 1960s, routine ipsilateral adrenalectomy (IA) has been considered an integral step in the removal of renal tumors as a part of a radical nephrectomy. However, recent data from the past decade have narrowed the indications for adrenalectomy and called into question the need for adrenalectomy at all in the treatment of renal cell carcinoma (RCC). We sought to identify the role of adrenalectomy in the treatment of RCC. Specifically, we wanted to answer the following questions: What is the incidence of ipsilateral adrenal involvement by cancer? How reliable is preoperative imaging? What is the rate of ipsilateral and contralateral metachronous recurrence? And finally, what are the potential noncancer sequelae from unnecessary removal of the adrenal gland? A systematic literature search of Embase, PubMed, Cochrane, and Ovid Medline was performed to identify studies evaluating the role of adrenalectomy during RCC surgery. Only articles published in English from the years 2000-2015 were included. Case reports, articles about primary adrenal tumors, letters to the editor, and surgical technique papers were excluded. We found little evidence to suggest that routine IA is associated with a higher risk of short-term surgical or medical complications. We did not find evidence that IA is associated with improved cancer control. Tomographic preoperative imaging of the adrenal gland demonstrating no cancer involvement is rarely wrong (<1% of the time), and the few adrenal lesions missed on imaging can often be identified intraoperatively. Some evidence indicates that IA may be associated with worse long-term survival. Adrenalectomy rates have been decreasing in recent years, reflecting a changing practice pattern. IA at the time of kidney surgery for a renal mass should be performed only if radiographic or intraoperative evidence indicates adrenal gland involvement. We sought to define the role of adrenalectomy in patients with kidney cancer. Although there are not high

    The purpose of this study was to examine the demographic, medical, and social cognitive determinants of exercise intentions in a population-based sample of multiple myeloma cancer survivors. Using a cross-sectional survey, 70 multiple myeloma cancer survivors completed a questionnaire that assessed their medical and demographic characteristics, past exercise behavior, and social cognitive exercise beliefs using the theory of planned behavior. Seventy participants provided valuable data. Descriptive statistics indicated that participants had quite positive instrumental attitude, intentions, and subjective norms and moderate levels of perceived behavioral control and affective attitudes for exercise. Forced entry multiple regression showed that the theory of planned behavior explained 43% of the variance in exercise intentions. Instrumental attitude and perceived behavioral control were both independent predictors of exercise intentions. No demographic or medical variable moderated the association between the theory of planned behavior constructs and exercise intentions. The results of the present investigation support the growing body of evidence confirming the utility of the theory of planned behavior to understand the salient determinants of exercise in cancer survivors. Knowledge gained from this study provides important information to oncology practitioners who are responsible for delivering supportive care interventions, including exercise, to patients diagnosed with multiple myeloma.

    Imaging plays an important role in the clinical management of cancer patients. Hybrid imaging with PET/computed tomography (CT) is having a broad impact in oncology, and in recent years PET/CT is beginning to have an impact in urooncology. In both bladder and renal cancers, there is a need to study the efficacy of other tracers than F-18 fluorodeoxyglucose (FDG), particularly tracers with limited renal excretion. Thus, new tracers are being introduced. This review focuses on the clinical role of FDG and other PET agents in renal, bladder, and testicular cancers.

    A case of synchronous triple urogenital cancer, which was comprised of renal cell carcinoma of the left kidney, transitional cell carcinoma of the urinary bladder, and adenocarcinoma of the prostate, is reported. A 72-year-old Japanese male patient was referred to our outpatient clinic with the complaint of asymptomatic hematuria. At that time, his serum of level of PSA was elevated to 20 ng/ml. Cystourethroscopy showed a papillary bladder tumor and coagula through the left urinary orifice. Ultrasonography, computed tomography and magnetic resonance imaging showed a mass lesion measuring about 6 cm by 5 cm in the left kidney. Angiography showed a hypervascular lesion measuring about 6 cm by 5 cm at the same site. Double cancer, consisting of renal cell carcinoma and transitional cell carcinoma of the urinary bladder, was suspected and we performed left total nephroureterectomy, hilar lymphadenectomy, and transurethral rection of the bladder tumor, one month later. At the same time, we performed a biopsy of the prostate. Histological diagnosis was renal cell carcinoma, clear cell carcinoma and transitional cell carcinoma of urinary bladder. Histological diagnosis of the prostate biopsy was moderately differentiated adenocarcinoma. Since this case fulfilled the criteria of Warren and Gates, it was classified as synchronous triple urogenital cancer. A review of the literature revealed 17 authentic cases of triple urogenital cancer, of which 14 and 10 cases were reported as a combination of renal cancer, bladder cancer and prostatic cancer, in the world and in Japan, respectively. Furthermore, he had been exposed to the atomic bomb explosion in Hiroshima in 1945. This carcinogenic precursor may be related to the development of the triple cancer. (author)

    Full Text Available High-cut-off hemodialysis (HCO-HD can effectively reduce high concentrations of circulating serum free light chains (sFLC in patients with dialysis-dependent acute kidney injury (AKI due to multiple myeloma (MM. Therefore, the aim of this study was to analyze renal recovery in a retrospective single-center cohort of dialysis-dependent MM patients treated with either conventional HD (conv. HD or HCO-HD.The final cohort consisted of 59 patients treated with HCO-HD (n = 42 or conv. HD (n = 17. A sustained sFLC response was detected in a significantly higher proportion of HCO-HD patients (83.3% compared with conv. HD patients (29.4%; p = 0.007. The median duration of sFLC required to reach values <1000 mg/l was 14.5 days in the HCO-HD group and 36 days in the conv. HD group. The corresponding rates of renal recovery were 64.3% and 29.4%, respectively (chi-squared test, p = 0.014. Multivariate regression and decision tree analysis (recursive partitioning revealed HCO-HD (adjusted odds ratio [OR] 6.1 [95% confidence interval (CI 1.5-24.5], p = 0.011 and low initial uric acid values (adjusted OR 1.3 [95%CI 1.0-1.7], p = 0.045 as independent and paramount variables associated with a favorable renal outcome.In summary, the results from this retrospective case-control study suggest in addition to novel agent-based chemotherapy a benefit of HCO-HD in sFLC removal and renal outcome in dialysis-dependent AKI secondary to MM. This finding was especially pertinent in patients with low initial uric acid values, resulting in a promising renal recovery rate of 71.9%. Further prospective studies are warranted.

  14. LMWH in cancer patients with renal impairment - better than warfarin?

    Bauersachs, Rupert M

    2016-04-01

    Venous thromboembolism (VTE) is one of the leading causes of death in cancer patients, which are known to have a 5- to 7-fold increased risk for VTE. The anticoagulant treatment of VTE in cancer patients is less effective with a three-fold increased risk of VTE recurrence compared to non-cancer patients, and it is less safe with more than double rates of major bleeding. Compared to vitamin-K antagonists (VKA), long-term secondary prevention with low molecular weight heparin (LMWH) has been shown to reduce the risk of recurrent VTE in cancer-associated thrombosis (CAT), and therefore, current international guidelines recommend the use of LMWH over VKA. With increasing age, cancer prevalence and VTE incidence increase while renal function decreases. Anti-cancer treatment may impair renal function additionally. Therefore, renal insufficiency is a frequent challenge in CAT patients, which is associated with a higher risk of both bleeding and recurrent VTE. Both VKA and LMWH may be associated with less efficacy and higher bleeding risk in renal insufficiency. Unfortunately, there is a lack of prospective data on renal insufficiency and CAT. A recent sub-analysis from a large randomized controlled trial shows that the bleeding risk in patients with severe renal insufficiency in CAT is not elevated with the use of LMWH compared to VKA while efficacy is maintained. In addition, LMWH treatment has several practical advantages over VKA, particularly in patients with CAT while they are receiving anti-cancer treatment.

    Acute kidney injury (AKI) is frequent in multiple myeloma (MM) patients and strongly affects prognosis, with particularly poor outcomes in patients requiring hemodialysis. Introduction of the novel therapeutic agents to MM therapy has improved myeloma response and renal outcome. This case series reviews the efficacy of combined systemic and extracorporeal therapy to further optimize time to light chain (serum-free light chain (sFLC)) reduction and renal recovery in MM patients with dialysis-dependent AKI (n = 19). High cut-off (HCO) hemodialysis for extracorporeal sFLC removal was initiated in parallel to chemotherapy. Combined therapy resulted in early sFLC response after a median of 13 (range 4-48) days and 6 (3-22) HCO hemodialysis sessions. Time to sFLC response was shorter in patients recovering renal function. Median time to dialysis independence was 15 (4-64) days. By intent-to-treat analysis, sustained renal recovery was achieved in 73.7% (77.8% adjusted for death) of patients. In multivariate analysis, duration of AKI prior to initiation of therapy was an independent predictor of renal functional outcome. Combining HCO hemodialysis for extracorporeal sFLC elimination and effective chemotherapy is a novel treatment strategy allowing for early and sustained sFLC reduction and a high proportion of renal recovery in these patients. Timely diagnosis and onset of therapy is essential for improving renal outcome.

Family history is associated with a two- to four-fold increase in risk, but the major forms of inherited predisposition together account for less than 4% of renal cell cancers. Cigarette smoking, obesity, and hypertension are the most consistently established risk factors. Analgesics have not been convincingly linked with renal cell cancer risk. A reduced risk of renal cell cancer among statin users has been hypothesized but has not been adequately studied. A possible protective effect of fruit and vegetable consumption is the only moderately consistently reported dietary finding, and, with the exception of a positive association with parity, evidence for a role of hormonal or reproductive factors in the etiology of renal cell cancer in humans is limited. A recent hypothesis that moderate levels of alcohol consumption may be protective for renal cell cancer is not strongly supported by epidemiologic results, which are inconsistent with respect to the categories of alcohol consumption and the amount of alcohol intake reportedly associated with decreased risk. For occupational factors, the weight of the evidence does not provide consistent support for the hypotheses that renal cell cancer may be caused by asbestos, gasoline, or trichloroethylene exposure. The established determinants of renal cell cancer, cigarette smoking, obesity, and hypertension, account for less than half of these cancers. Novel epidemiologic approaches

    The authors report an uncommon case of bilateral synchronous adrenal gland metastases from left renal cell carcinoma. The diagnosis was established by abdominal ultrasound and computed tomography. The surgical approach initially consisted of left radical nephrectomy and ipsilateral adrenalectomy. Histologically, the tumor of the left adrenal gland was identical to the left renal cell carcinoma. Subsequent contralateral adrenalectomy showed an adrenal metastasis identical to the left renal cell carcinoma. Patient follow-up was good with no recurrence of the disease after one year. This is an uncommon case for renal cancer. The treatment and prognosis are discussed.

    Renal impairment is associated with poor prognosis in myeloma. This analysis of the pivotal phase 3 FIRST trial examined the impact of renally adapted dosing of lenalidomide and dexamethasone on outcomes of patients with different degrees of renal impairment. Transplant-ineligible patients not requiring dialysis were randomized 1:1:1 to receive continuous lenalidomide and dexamethasone until disease progression (n=535) or for 18 cycles (72 weeks; n=541), or melphalan, prednisone, and thalidomide for 12 cycles (72 weeks; n=547). Follow-up is ongoing. Patients were grouped by baseline creatinine clearance into no (≥ 80 mL/min [n=389]), mild (≥ 50 to < 80 mL/min [n=715]), moderate (≥ 30 to < 50 mL/min [n=372]), and severe impairment (< 30 mL/min [n=147]) subgroups. Continuous lenalidomide and dexamethasone therapy reduced the risk of progression or death in no, mild, and moderate renal impairment subgroups vs. melphalan, prednisone, and thalidomide therapy (HR = 0.67, 0.70, and 0.65, respectively). Overall survival benefits were observed with continuous lenalidomide and dexamethasone treatment vs. melphalan, prednisone, and thalidomide treatment in no or mild renal impairment subgroups. Renal function improved from baseline in 52.6% of lenalidomide and dexamethasone-treated patients. The safety profile of continuous lenalidomide and dexamethasone was consistent across renal subgroups, except for grade 3/4 anemia and rash, which increased with increasing severity of renal impairment. Continuous lenalidomide and dexamethasone treatment, with renally adapted lenalidomide dosing, was effective for most transplant-ineligible patients with myeloma and renal impairment.

    Renal impairment is associated with poor prognosis in myeloma. This analysis of the pivotal phase 3 FIRST trial examined the impact of renally adapted dosing of lenalidomide and dexamethasone on outcomes of patients with different degrees of renal impairment. Transplant-ineligible patients not requiring dialysis were randomized 1:1:1 to receive continuous lenalidomide and dexamethasone until disease progression (n=535) or for 18 cycles (72 weeks; n=541), or melphalan, prednisone, and thalidomide for 12 cycles (72 weeks; n=547). Follow-up is ongoing. Patients were grouped by baseline creatinine clearance into no (≥ 80 mL/min [n=389]), mild (≥ 50 to < 80 mL/min [n=715]), moderate (≥ 30 to < 50 mL/min [n=372]), and severe impairment (< 30 mL/min [n=147]) subgroups. Continuous lenalidomide and dexamethasone therapy reduced the risk of progression or death in no, mild, and moderate renal impairment subgroups vs. melphalan, prednisone, and thalidomide therapy (HR = 0.67, 0.70, and 0.65, respectively). Overall survival benefits were observed with continuous lenalidomide and dexamethasone treatment vs. melphalan, prednisone, and thalidomide treatment in no or mild renal impairment subgroups. Renal function improved from baseline in 52.6% of lenalidomide and dexamethasone–treated patients. The safety profile of continuous lenalidomide and dexamethasone was consistent across renal subgroups, except for grade 3/4 anemia and rash, which increased with increasing severity of renal impairment. Continuous lenalidomide and dexamethasone treatment, with renally adapted lenalidomide dosing, was effective for most transplant-ineligible patients with myeloma and renal impairment. PMID:26659916

    Abstract Introduction We have previously reported that Myeov (MYEloma OVerexpressed gene) expression is enhanced in colorectal cancer (CRC) and that it promotes CRC cell proliferation and invasion. The role of Myeov in CRC migration is unclear. ProstaglandinE2 (PGE 2) is a known factor in promoting CRC carcinogenesis. The role of PGE 2 in modulating Myeov expression has also not been defined. Aim To assess the role of Myeov expression in CRC cell migration and to evaluate the role of PGE 2 in Myeov bioactivity. Methods siRNA mediated Myeov knockdown was achieved in T84 CRC cells. Knockdown was assessed using quantitative real time PCR. The effect of knockdown on CRC cell migration was assessed using a scratch wound healing assay. Separately, T84 cells were treated with PGE 2 (0.00025 μ M, 0.1 μ M and 1 μ M) from 30 min to 3 hours and the effect on Myeov gene expression was assessed using real time PCR. Results Myeov knockdown resulted in a significant reduction in CRC cell migration, observable as early as 12 hours (P < 0.05) with a 39% reduction compared to control at 36 hours (p < 0.01). Myeov expression was enhanced after treatment with PGE 2, with the greatest effect seen at 60 mins for all 3 PGE 2 doses. This response was dose dependent with a 290%, 550% & 1,000% increase in Myeov expression for 0.00025 μ M, 0.1 μ M and 1 μ M PGE 2 respectively. Conclusion In addition to promoting CRC proliferation and invasion, our findings indicate that Myeov stimulates CRC cell migration, and its expression may be PGE 2 dependant.

    Full Text Available Introduction. Multiple myeloma is a hemathological malignancy characterized by the clonal proliferation of plasma cells in the bone the marrow. Extramedullary dissemination of multiple myeloma is uncommon. In several cases only, the multiple myeloma malignant plasma cells had diseminated to the lung parenchyma. Case report. We presented a case of multiple myeloma with lung plasmacytoma, in a 79-year-old patient, hospitalized for febrility and infiltrative mass in the right lung. Two months before the patient was admitted, because of developing terminal renal failure, hemodialysis treatment had started three times a week. Since then, the patient was oliguric, but because of febrility and hemoptysis that appeared, at first he was treated with dual antibiotic therapy which resulted in temporary improvement of his general condition, but pleural effusion remained. After thoracocentesis, followed by myelogram, the multiple myeloma diagnosis was established. Conclusion. In patients of middle and older age, with general weakness, exhaustion, loss of weight, renal failure which progresses to the end stage rapidly, if symptoms of respiratory tract occur, consider this uncommon disease - extramedullary dissemination of multiple myeloma.

    Triiodothyronine plays an important role in the regulation of kidney cell growth, differentiation and metabolism. Patients with renal cell cancer who develop hypothyreosis during tyrosine kinase inhibitor (TKI) treatment have statistically longer survival. In this study, we developed cell based model of triiodothyronine (T3) analysis in RCC and we show the different effects of T3 on renal cell cancer (RCC) cell growth response and expression of the thyroid hormone receptor in human renal cell cancer cell lines from primary and metastatic tumors along with human kidney cancer stem cells. Wild-type thyroid hormone receptor is ubiquitously expressed in human renal cancer cell lines, but normalized against healthy renal proximal tube cell expression its level is upregulated in Caki-2, RCC6, SKRC-42, SKRC-45 cell lines. On the contrary the mRNA level in the 769-P, ACHN, HKCSC, and HEK293 cells is significantly decreased. The TRβ protein was abundant in the cytoplasm of the 786-O, Caki-2, RCC6, and SKRC-45 cells and in the nucleus of SKRC-42, ACHN, 769-P and cancer stem cells. T3 has promoting effect on the cell proliferation of HKCSC, Caki-2, ASE, ACHN, SK-RC-42, SMKT-R2, Caki-1, 786-0, and SK-RC-45 cells. Tyrosine kinase inhibitor, sunitinib, directly inhibits proliferation of RCC cells, while thyroid hormone receptor antagonist 1-850 (CAS 251310‑57-3) has less significant inhibitory impact. T3 stimulation does not abrogate inhibitory effect of sunitinib. Renal cancer tumor cells hypostimulated with T3 may be more responsive to tyrosine kinase inhibition. Moreover, some tumors may be considered as T3-independent and present aggressive phenotype with thyroid hormone receptor activated independently from the ligand. On the contrary proliferation induced by deregulated VHL and or c-Met pathways may transgress normal T3 mediated regulation of the cell cycle.

    Full Text Available Abstract Renal metastasis from non-small cell lung cancer is rather uncommon. The mechanism underlying the occurrence of metastasis in this site is still not well understood. We report a case of a 53-year-old Chinese woman who had moderately differentiated squamous cell carcinoma of the lung. After a ten months post-surgery interval of disease free survival, computed tomography (CT scan found that left renal parenchymal was occupied by a mass, confirmed by kidney biopsy to be a metastasis from squamous cell lung carcinoma. Based on this case, we are warned to be cautious in diagnosis and treatment when renal lesion are detected.

  10. Kidney Disease and Multiple Myeloma

    Summary Kidney injury is a common complication of multiple myeloma and other plasma cell dyscrasias, and it is associated with increased mortality. Multiple pathogenic mechanisms can contribute to kidney injury in the patient with myeloma, some of which are the result of nephrotoxic monoclonal Ig and some of which are independent of paraprotein deposition. The pathogenic mechanisms that underlie paraprotein-related kidney disease are increasingly well understood. A novel assay allowing the quantification of free light chains in the serum has aided the diagnosis of new onset disease and allowed for the earlier detection of relapse. Novel myeloma agents have shown considerable promise in reversing renal failure in some patients and improving outcomes. Stem cell transplantation remains a mainstay of management for younger patients with myeloma who are suitable candidates for intensive therapy, whereas the role of new drugs, plasma exchange, and kidney transplantation continues to evolve.

    Skin metastases from either prostate adenocarcinoma or multiple myeloma rarely occur. We report the case of a 73-year-old man with multiple myeloma who presented with multiple subcutaneous nodules 3 years after his initial diagnosis. Fluorine-18 fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) imaging was suggestive of a concomitant second primary from the prostate. This case highlights not only a rare initial manifestation of prostate cancer, but also the role of 18F-FDG-PET/CT in detecting a clinically unsuspected second malignancy. It potentially corroborates the possible association of both diseases, as has been reported before.

    The renal cell carcinomas (RCC) denote a diverse set of neoplasias with unique genetic and histological features. The RCCs emanate from the renal tubule, a highly heterogeneous epithelial structure, and depending on which cell is malignified the resulting cancer displays unique characteristics. Notwithstanding this, the cells of origin for the RCC forms are far from established, and only inferred by the accumulated weight of marker similarities, not always providing an unequivocal picture. The tubular epithelium is normally mitotically quiescent, but demonstrates a considerable regenerative capacity upon renal injury. Recently the hypothesis that regeneration is driven by adult stem cells has been added experimental support, providing further complexity to the issue of renal carcinogenesis. Whether these cells are linked to RCC is an open question. In the present review we therefore present the prevailing theories regarding kidney regeneration, since a better understanding of this process might be of relevance when considering the different malignancies that arise from kidney epithelium. Our own results show that papillary renal cell carcinoma displays considerable similarities to proximal tubular progenitor cells and we suggest that this tumor form may develop in a multi-step fashion via benign renal adenomas. The putative connection between renal stem cells and carcinomas is, however, not clarified, since the current understanding of the renal stem cell system is not complete. It is clear that the efforts to isolate and characterize renal progenitor/stem cells suffer from numerous technical limitations and that it remains likely that the kidney harbors different stem cell pools with a restricted differentiation potential.

    This study was designed to analyze the impact of multi-targeted tyrosine kinase inhibitors on the cancer stem cell subpopulation in renal cell cancer. The second objective was to evaluate the effect of tumor growth inhibition related to a tumor niche factor - oxygen deprivation - as hypoxia develops along with the anti-angiogenic activity of tyrosine kinase inhibitors in renal tumors. Cells were treated with tyrosine kinase inhibitors, sunitinib, sorafenib and axitinib, in 2D and 3D culture conditions. Cell proliferation along with drug toxicity were evaluated. It was shown that the proliferation rate of cancer stem cells was decreased by the tyrosine kinase inhibitors. The efficacy of the growth inhibition was limited by hypoxic conditions and 3D intratumoral cell-cell interactions. We conclude that understanding the complex molecular interaction feedback loops between differentiated cancer cells, cancer stem cells and the tumor microenvironment in 3D culture should aid the identification of novel treatment targets and to evalute the efficacy of renal cancer therapies. Cell-cell interaction may represent a critical microenvironmental factor regulating cancer stem cell self-renewal potential, enhancing the stem cell phenotype and limiting drug toxicity. At the same time the role of hypoxia in renal cancer stem cell biology is also significant.

    Metastasis is a process consisting of cells spreading from the primary site of the cancer to distant parts of the body. Our understanding of this spread is limited and molecular mechanisms causing particular characteristics of metastasis are still unknown. There is some evidence that primary renal cell carcinoma (RCC) and metastases of RCC exhibit molecular differences that may effect on the biological characteristics of the tumor. Some authors have detected differences in clear cell and nonclear cell component between these 2 groups of tumors. Investigators have also determined that primary RCC and metastases of RCC diverge in their range of renal-specific markers and other protein expression, gene expression pattern, and microRNA expression. There are also certain proteins that are variously expressed in primary RCCs and their metastases and have effect on clinical outcome, e.g., endothelin receptor type B, phos-S6, and CD44. However, further studies are needed on large cohorts of patients to identify differences representing promising targets for prognostic purposes predicting disease-free survival and the metastatic burden of a patient as well as their suitability as potential therapeutic targets. To sum up, in this review we have attempted to summarize studies connected with differences between primary RCC and its metastases and their influence on the biological characteristics of renal cancer.

    Using target-specific short interfering (si) RNAs, we silenced the tandem endocytic receptors megalin and cubilin genes in cultured human renal proximal tubule epithelial cells. Transfection by siRNA resulted in up to 90% suppression of both megalin and cubilin protein and mRNA expression. In HK-2 cells exposed to kappa-light chain for up to 24 h, light chain endocytosis was reduced in either megalin- or cubilin-silenced cells markedly but incompletely. Simultaneous silencing of both the cubilin and megalin genes, however, resulted in near-complete inhibition of light chain endocytosis, as determined by measuring kappa-light chain protein concentration in cell cytoplasm and by flow cytometry using FITC-labeled kappa-light chain. In these cells, light chain-induced cytokine responses (interleukin-6 and monocyte chemoattractant protein-1) and epithelial-to-mesenchymal transition as well as the associated cellular and morphological alterations were also markedly suppressed. The results demonstrate that light chain endocytosis is predominantly mediated by the megalin-cubilin tandem endocytic receptor and identify endocytosis as a key step in light chain cytotoxicity. Blocking light chain endocytosis prevents its nephrotoxic effects on human kidney proximal tubule cells.

    Globally, renal cell carcinomas (RCCs) represent a major portion of patients suffering from cancer. Temsirolimus is an anti-renal cancer drug that has already been approved in poor-risk metastatic RCC (mRCC) patients. In our present study, we have evaluated the in vitro effect of varying concentrations of temsirolimus on cancerous rat kidney cystatin; renal cancer was induced in rats making use of dimethylnitrosamine (DMN). It has already been reported that cancerous rat kidney cystatin performs its activity in an efficacious manner as compared to normal rat kidney cystatin, so here an attempt was made to see the effect of temsirolimus on this increased activity of cystatin in renal cancers. Anti-papain activity assay was utilized to see this effect and it was found that temsirolimus reduces the increased activity of cancerous rat kidney cystatin similar to that of normal rat kidney cystatin. Further, to have an insight into temsirolimus induced structural alterations in cancerous rat kidney cystatin; various spectroscopic assays viz. UV, Fluorescence, Circular dichroism (CD) and FTIR spectroscopy were employed. UV and Fluorescence spectroscopy shows cancerous rat kidney cystatin transformation to normal form in the presence of temsirolimus. FTIR and CD spectroscopy confirmed the complete structural reversion of cancerous rat kidney cystatin to normal form in the presence of 40μM temsirolimus. Thus, it can said that temsirolimus causes renal cystatin to revert to normal form; the increased activity of renal cystatin observed in incidences of renal cancer is restored back to normal thereby halting the progression of renal cancer.

    Renal cell cancer (RCC) is the common denominator for a heterogeneous group of diseases. The subclassification of these tumours is based on histological type and molecular pathogenesis. Insight into molecular pathogenesis has led to the development of targeted systemic therapies. Genetic susceptibility is the principal cause of RCC in about 2-4% of cases. Hereditary RCC is the umbrella term for about a dozen different conditions, the most frequent of which is von Hippel-Lindau disease . Here, we describe the main hereditary RCC syndromes, consider criteria for referral of RCC patients for clinical genetic assessment and discuss management options for patients with hereditary RCC and their at-risk relatives.

    There were observed 30 patients (32 tumors), to whom preoperatively for renal-cell cancer (ROC) a neoadjuvant target therapy (NATTH) was conducted. In 19 (66.7%) of them a pazopanib (800 mg per os once a day through 2 mo) was applied, and in 10 (33.3%)--sunitinib (50 mg per os once a day through 28 days, the gap--14 days, repeated course--28 days). The indications for the NATTH conduction were: in 7 (21.9%) patients--a locally--spread RCC with the objective to localize a tumor and to search a further possibility of radical surgical intervention performance, and in 25 (78.1%)--the tumor reduction and searching possibility of the organpreserving treatment conduction. The NATTH conduction in the patients, suffering RCC, have guaranteed a primary pathological focus reduction in 90% of observations, and a partial regression in accordance to the RECIST criteria--in 28.1%. A tumor reduction by (22.9 ± 17.8)% at average have permitted to perform a renal resection in 75% of observations, concerning localized RCC, when indication of preservation of enough functioning renal parenchyma was secured.

    Patients with asymptomatic or smoldering multiple myeloma should not be treated but should be observed closely for progression. For symptomatic myeloma, chemotherapy is indicated. Melphalan, the agent of choice, should be given with prednisone for 1 week of every 6 weeks, If melphalan brings no response, or response and then relapse, cyclophosphamide (Cytoxan) should be give intravenously every 4 weeks or orally every day. BCNU, CCNU, and doxorubicin (Adriamycin) have also shown activity in myeloma. Hypercalcemia occurs in one-third of patients and should be countered with hydration, corticosteroids, Neutra-Phos, or mithramycin. Long-term hemodialysis has achieved some success. The combination of sodium flouride and calcium carbonate produces new bone formation; it seems a useful adjunct in treatment for myelomatous bone disease. Radiation should be utilized only for severe, localized pain or for solitary lesions. Survival with multiple myeloma varies, mean durations being 2 to 3 years. Multivariate analysis indicates that serum creatinine and calcium levels are the most significant indicators regarding 2-year survival. We have found monoclonal proteinuria not significantly more frequent with renal insufficiency than with normal renal function, renal insufficiency not significantly more frequent with lambda than with kappa chains, and survival not significantly greater with IgG myeloma than with IgA.

    Traf2- and Nck-interacting kinase (TNIK) is a member of the germinal center kinase family. TNIK was first identified as a kinase that is involved in regulating cytoskeletal organization in many types of cells, and it was recently proposed as a novel therapeutic target in several types of human cancers. Although previous studies suggest that TNIK plays a pivotal role in cancer cell survival and prognosis, its function in hematological cancer cell survival has not been investigated. Here we investigated the relationship between TNIK function and cell viability in multiple myeloma IM-9 cells using TNIK small interfering RNA (siRNA) transfection and dovitinib treatment. Treatment of IM-9 cells with TNIK siRNA and dovitinib treatment reduced cell proliferation. The ATP competing kinase assay and western blot analysis showed that dovitinib strongly inhibited both the interaction of TNIK with ATP (K i, 13 nM) and the activation of Wnt signaling effectors such as β-catenin and TCF4. Dovitinib also induced caspase-dependent apoptosis in IM-9 cells without significant cytotoxicity in PBMCs. Our results provide new evidence that TNIK may be involved in the proliferation of multiple myeloma IM-9 cells and in the anti-cancer activity of dovitinib via inhibition of the endogenous Wnt signaling pathway.

    Renal cell cancer rarely metastasizes to the thyroid gland, and it has been reported to present as a solitary mass. We present a case of diffuse thyroid cancer metastases from renal cell cancer. Bilateral internal jugular vein tumor thrombi were also present. To the best of our knowledge, this is the first description of diffuse thyroid metastases from renal cell cancer in the English literature. Renal cell cancer metastases should be considered in the differential of thyroid imaging abnormalities arising in the setting of known renal cell carcinoma, particularly late in the course of disease. This is frequently associated with internal jugular vein thrombi, which should be evaluated with an abnormal thyroid. Thyroglobulin levels are usually normal in such patients.

    Esophageal cancer-related gene 4 (ECRG4) has been proposed as a putative tumor suppressor gene in several tumors. However, the role and regulation of ECRG4 in the pathogenesis of human renal cancer remain largely unknown. Our current study revealed that expression of ECRG4 is downregulated in renal cell lines and renal cancer tissues. ECRG4 expression was significantly associated with histological grade of tumors (p renal cancer patients. Silencing of ECRG4 expression in renal cell lines was associated with its promoter methylation. Moreover, ectopic expression of ECRG4 markedly inhibited cell proliferation and invasion in renal cancer cell lines. These results indicated that ECRG4 is frequently silenced by the methylation of promoter in renal cell cancers. ECRG4 may be a tumor suppressor in renal cancer and serve as a prognostic marker.

    We assessed efficacy, safety, and reversal of renal impairment (RI) in untreated patients with multiple myeloma given bortezomib-melphalan-prednisone-thalidomide followed by bortezomib-thalidomide (VMPT-VT) maintenance or bortezomib-melphalan-prednisone (VMP). Exclusion criteria included serum creatinine ≥ 2.5 mg/dL. In the VMPT-VT/VMP arms, severe RI (estimated glomerular filtration rate [eGFR] ≤ 30 mL/min), moderate RI (eGFR 31-50 mL/min), and normal renal function (eGFR > 50 mL/min), were 6%/7.9%, 24.1%/24.9%, and 69.8%/67.2%, respectively. Statistically significant improvements in overall response rates and progression-free survival were observed in VMPT-VT versus VMP arms across renal cohorts, except in severe RI patients. In the VMPT group, severe RI reduced overall survival (OS). RI was reversed in 16/63 (25.4%) patients receiving VMPT-VT versus 31/77 (40.3%) receiving VMP. Multivariate analysis showed male sex (P = .022) and moderate RI (P = .003) significantly predicted RI recovery. VMP patients achieving renal response showed longer OS. In both arms, greater rates of severe hematologic adverse events were associated with RI (eGFR < 50 mL/min), however, therapy discontinuation rates were unaffected. VMPT-VT was superior to VMP for cases with normal renal function and moderate RI, whereas VMPT-VT failed to outperform VMP in patients with severe RI, although the relatively low number of cases analyzed preclude drawing definitive conclusions. VMPT-VT had no advantage in terms of RI reversal over VMP.

    Full Text Available Anemia é uma complicação comum em pacientes com mieloma múltiplo (MM e ocorre em mais de 2/3 dos pacientes. Anemia de doença crônica, deficiência de eritropoetina (EPO devido à insuficiência renal e efeito mielossupressivo da quimioterapia são os principais mecanismos patofisiológicos que contribuem para o desenvolvimento de anemia no MM. Nos pacientes que obtêm remissão completa com tratamento quimioterápico, anemia usualmente se normaliza. Nos pacientes que não respondem ou apresentam recaída do mieloma, anemia freqüentemente persiste. As opções de tratamento dos pacientes anêmicos com MM incluem transfusões de hemácias e EPO recombinante humana. Essa proteína é biologicamente equivalente à EPO endógena e sua administração promove aumento dos valores de hemoglobina por tempo mais prolongado sem os riscos das transfusões de sangue. Vários estudos têm relatado melhora significante da eritropoese, redução da necessidade transfusional e melhora da qualidade de vida com o uso da EPO como tratamento a longo prazo da anemia associada ao mieloma. Nesse artigo, propomos o tratamento da anemia do MM baseado nas recomendações propostas pela Sociedade Americana de Hematologia (ASH em conjunto com a Sociedade Americana de Oncologia Clínica (ASCO, pela Organização Européia para Pesquisa e Tratamento do Câncer (EORTC, pelo IMF (Internacional Myeloma Foundation e pelo NCCN (National Comprehensive Cancer Network.Anemia is a common complication in patients with multiple myeloma (MM occurring in more than two thirds of all patients. Anemia of chronic diseases, erythropoietin (EPO deficiency due to renal impairment and the myelosuppressive effect of chemotherapy are the most important pathophysiological mechanisms contributing to the development of anemia in MM. In patients who achieve complete remission after chemotherapy, anemia usually normalizes. Non-responders and relapsing myeloma patients often continue to suffer

  3. Fibroblast growth factor receptor 3 interacts with and activates TGFβ-activated kinase 1 tyrosine phosphorylation and NFκB signaling in multiple myeloma and bladder cancer.

    Directory of Open Access Journals (Sweden)

    Full Text Available Cancer is a major public health problem worldwide. In the United States alone, 1 in 4 deaths is due to cancer and for 2013 a total of 1,660,290 new cancer cases and 580,350 cancer-related deaths are projected. Comprehensive profiling of multiple cancer genomes has revealed a highly complex genetic landscape in which a large number of altered genes, varying from tumor to tumor, impact core biological pathways and processes. This has implications for therapeutic targeting of signaling networks in the development of treatments for specific cancers. The NFκB transcription factor is constitutively active in a number of hematologic and solid tumors, and many signaling pathways implicated in cancer are likely connected to NFκB activation. A critical mediator of NFκB activity is TGFβ-activated kinase 1 (TAK1. Here, we identify TAK1 as a novel interacting protein and target of fibroblast growth factor receptor 3 (FGFR3 tyrosine kinase activity. We further demonstrate that activating mutations in FGFR3 associated with both multiple myeloma and bladder cancer can modulate expression of genes that regulate NFκB signaling, and promote both NFκB transcriptional activity and cell adhesion in a manner dependent on TAK1 expression in both cancer cell types. Our findings suggest TAK1 as a potential therapeutic target for FGFR3-associated cancers, and other malignancies in which TAK1 contributes to constitutive NFκB activation.

    The acronym CRAB summarizes the most typical clinical manifestations of multiple myeloma, these being hypercalcemia, renal failure, anemia, and bone disease. CRAB can be used to distinguish between active, symptomatic multiple myeloma and monoclonal gammopathy of undermined significance or smoldering myeloma. The distinction is relevant not only for classification and diagnosis but also for therapy. CRAB factors influence the prognosis of multiple myeloma. However, it is unclear whether the presence of CRAB factors has an influence on the prognosis of myeloma treated with novel agents. In the current study, patients with hypercalcemia and bone disease showed a significantly worse prognosis, whereas anemia and renal failure showed no difference in survival. Novel agents used for treatment of patients with renal failure suggested a favorable outcome compared with conventional therapy. Bone disease was the most common factor and may have the strongest prognostic value in symptomatic myeloma patients using novel agents. PMID:28286629

    Surgical difficulties of renal transplantation related to prostate cancer (PC) treatment and the results of renal transplantation after radical prostatectomy are currently poorly known, as well as oncological follow-up before and after renal transplantation. We performed a retrospective study including all patients diagnosed with PC before renal transplantation in our department. Nineteen patients were included between August 2003 and December 2013. The mean age at diagnosis of PC was 61.7 years (range 51.4-71.1). PSA mean level at diagnosis was 8.5 ng/ml (range 4.8-20). Fourteen had a retro-pubic and 5 a laparoscopic prostatectomy. Three patients underwent radiotherapy for positive surgical margins or extra-capsular extension. Fourteen patients were transplanted. The mean time lapse between prostatectomy and kidney transplantation was 32.8 months (range 14-71). Seven recipients (50%) were transplanted less than 24 months after prostatectomy. Post-transplantation surgical complications were not significantly related to dissection difficulties (p=0.2). No recurrence of PC was observed after renal transplantation, with a mean follow-up of 38 months (range 6-77.9). Prostate cancer discovered before renal transplantation should be treated by radical prostatectomy to assess recurrence risk. If the PC is at low risk of recurrence, it seems possible to shorten the 2-year period of oncologic follow-up before transplantation called for in current recommendations.

    Full Text Available Multiple myeloma is a malignant proliferation of monoclonal plasma cells leading to clinical features that include hypercalcaemia, renal dysfunction, anaemia, and bone disease (frequently referred to by the acronym CRAB which represent evidence of end organ failure. Recent evidence has revealed myeloma to be a highly heterogeneous disease composed of multiple molecularly-defined subtypes each with varying clinicopathological features and disease outcomes. The major division within myeloma is between hyperdiploid and nonhyperdiploid subtypes. In this division, hyperdiploid myeloma is characterised by trisomies of certain odd numbered chromosomes, namely, 3, 5, 7, 9, 11, 15, 19, and 21 whereas nonhyperdiploid myeloma is characterised by translocations of the immunoglobulin heavy chain alleles at chromosome 14q32 with various partner chromosomes, the most important of which being 4, 6, 11, 16, and 20. Hyperdiploid and nonhyperdiploid changes appear to represent early or even initiating mutagenic events that are subsequently followed by secondary aberrations including copy number abnormalities, additional translocations, mutations, and epigenetic modifications which lead to plasma cell immortalisation and disease progression. The following review provides a comprehensive coverage of the genetic and epigenetic events contributing to the initiation and progression of multiple myeloma and where possible these abnormalities have been linked to disease prognosis.

    Full Text Available Abstract Introduction – Acute renal failure (ARF has a poor prognosis in patients with cancer requiring intensive care unit (ICU admission. Our aim is finding prognostic factors for hospital mortality in patients with cancer with ARF requiring renal replacement therapy (RRT. Methods – In this retrospective study, all patients with cancer with ARF treated with continuous venovenous filtration (CVVHDF in the ICU of the Institut Jules Bordet, between January 1st 2003 and December 31st 2012, were included in the study.Results – 103 patients are assessed: men/women 69/34, median age 62 years, solid/haematologic tumours 68/35, median SAPS II 56. Mortality rate was 63%. Seven patients required chronic renal dialysis. After multivariate analysis, two variables were statistically associated with hospital mortality : more than one organ failure (including kidney (OR 5.918 ; 95% CI 2.184 – 16.038 ; p<0,001 and low albumin level (OR 3.341; 95% CI 1.229 – 9.077; p=0,02. Only minor complications related to CVVHDF have been documented.Conclusions – Despite the poor prognosis associated with ARF, CVVHDF is an effective and tolerable renal replacement technique in patients with cancer admitted to the ICU. Multiple organ failure and hypoalbuminemia, two independent prognostic factors for hospital mortality have to be considered when deciding for introducing RRT.

  10. Delaying Renal Transplant after Radical Prostatectomy for Low-Risk Prostate Cancer.

    To minimize the recurrence of a previously treated neoplasm in organ recipients, a period of 2 to 5 years without recurrence is advocated for most malignancies. However, prostate cancer is different because of its biological properties, diagnosis, and treatment. Most prostate cancers are detected at a low stage and demonstrate slow growth after detection. Definitive treatment with radical prostatectomy affords excellent results. Renal transplant candidates with early-stage prostate cancer have a higher risk of dying on dialysis than dying from prostate cancer; therefore, renal transplant candidates with organ-confined prostate cancer should be immediately considered for transplant.

    Epigenetic inactivation of Ras-associated domain family 1A (RASSF1A) by hyper-methylation of its promoter region has been identified in various cancers. However, the role of RASSF1A in renal cancer has neither been thoroughly investigated nor reviewed. In this study, we reviewed and performed a meta-analysis of 13 published studies reporting correlations between methylation frequency of the RASSF1A promoter region and renal cancer risk. The odds ratios (ORs) of eligible studies and their corresponding 95% confidence intervals (95%CIs) were used to correlate RASSF1A promoter methylation with renal cell cancer risk and clinical or pathological variables, respectively. RASSF1A promoter methylation was significantly associated with the risk of renal cell cancer (OR = 19.35, 95%CI = 9.57-39.13). RASSF1A promoter methylation was significantly associated with pathological tumor grade (OR = 3.32, 95%CI = 1.55-7.12), and a possible positive correlation between RASSF1A promoter methylation status and tumor stage was noted (OR = 1.89, 95%CI = 1.00-3.56, P = 0.051). Overall, this meta-analysis demonstrated that RASSF1A promoter methylation is significantly associated with increased risk of renal cell cancer. RASSF1A promoter methylation frequency was positively correlated with pathological tumor grade, but not the clinical stage. This study showed that RASSF1A promoter methylation could be utilized to predict renal cell cancer prognosis.

    Full Text Available Renal squamous cell cancer is one of the rare primary urothelial tumors with only a handful of cases reported in literature. Because of high grade, advanced and late presentation, they herald a grave prognosis. They are frequently associated with calculus disease, smoking, phenacetin consumption and foci of squamous metaplasia due to chronic irritation. Nephroureterectomy is the treatment of choice for such tumors. We hereby present a case of 59 year old female who presented with squamous cell cancer of renal pelvis. The case presented here is different from what has already been reported in literature, as the patient had no antecedent risk factors for renal squamous cell carcinoma.-------------------------------------------------Cite this article as: Pahwa M, Pahwa AR, Girotra M, Chawla A.

    Full Text Available Multiple myeloma is a disease resulting from clonal proliferation of plasma cells. A disease of the elderly, jaw lesions are seen in 14% of patients affected with myeloma. Rarely the oral and maxillofacial lesions can be the first manifestation of the disease. We report the case of a 75-year-old man who presented with mandibular swelling. Fine-needle aspiration cytology was done from the swelling and smears were suggestive of anaplastic myeloma, which is a rare and aggressive variant of myeloma. The diagnosis of a plasmacytoma was confirmed by biopsy. Further workup of the patient revealed osteolytic lesions in skull, M band in electrophoresis and evidence of renal failure. Peripheral smear and bone marrow findings were also consistent with myeloma.

Current first-line therapeutics for the advanced-stage RCC include antiangiogenic drugs that have yielded high rates of objective clinical response; however, these tend to be transient in nature, with many patients becoming refractory to chronic treatment with these agents. Adjuvant immunotherapies remain viable candidates to sustain disease-free and overall patient survival. In particular, vaccines designed to optimize the activation, maintenance, and recruitment of specific immunity within or into the tumor site continue to evolve. Based on the integration of increasingly refined immunomonitoring systems in both translational models and clinical trials, allowing for the improved understanding of treatment mechanism(s of action, further refined (combinational vaccine protocols are currently being developed and evaluated. This review provides a brief history of RCC vaccine development, discusses the successes and limitations in such approaches, and provides a rationale for developing combinational vaccine approaches that may provide improved clinical benefits to patients with RCC.Keywords: renal cell carcinoma, vaccines, immunotherapy, combinational therapy, cellular immunity

    Liver transplantation is associated with a significantly increased risk of de novo malignancies, but for renal cancer this risk is less clear. We therefore performed a meta-analysis of published studies to determine whether renal cancer risk in liver transplant recipients (LTRs) was increased. To obtain a more precise conclusion, a systematic search was performed in PubMed and Web of Science databases until June 10, 2015. Standardized incidence ratio (SIR) corresponding 95% confidence interval (CI) were used to estimate risk of renal cancer in LTRs. Heterogeneity test, sensitivity analysis, and publishing bias were also performed. We identified 8 eligible studies and performed a meta-analysis on data of 49,654 LTRs with a total follow-up of 121,514.6 patient-years. The SIR for renal cancer was identified a 3.275-fold higher SIR (95% CI: 1.857-5.777; P renal cancer. Such association suggests that yearly routine post-transplant surveillance is need for renal cancer in LTRs.

    Multiple Myeloma(MM)is characterised by the accumulation of malignanat plasma cells in the bone marrow producing a monocolonal immungoglobulin.The standard conventiona therapy in the combination of melphalan and prednisone resulting in a response rate of 40%-60% and in a median survival time of approximately 3 years.In order to improve the therapeutic efficacy va rious combination regimens have been tested.Most randomized trials have frailed to show a significant improvement in survival time when combination chemotherapy is used instead of melphalan with or without prednisone.The benefit of maintenance therapy with interferon-alpha has been demonstrated.The toxicity of interferon-alpha,which may reduce the quality of life,should be considered.Recently,myeloma-treatment has been modified.High-dose chemotherapy accompaniced by hematopoietic stem-cell support via autologous transplant is recommended up to the age of 65-70 years.First results from a French study comparing single versus double autologous transplantaiton have shown a benefit in terms of event-free survival for the sequential approach.Vaccinations as an adoptive immuntherapy to treat minimal residual dsease are umder way.The mortality rate of allogeneic transplantation of hemaatopoietic stem cells has been reduced in the last 5 years.The use of reduced conditioning regimens or the partial depletion of T cells in peripheral blood stem cell transplants in an effort to decrease transplant related mortality are promising approaches.Thalidomide and its derivates are a new class of agents with independent anti-tumour activity in MM.Encouraging results with this antiangiogenic therapy in phase Ⅱ trials have been reported.Supportive therapies,such as the treatment of anaemia with erythropoietin,the management of renal failure and the use of bisphosphonates,improve the life quality of MM patients.

    Renal dysfunction predicts all-cause mortality in general population. However, the prevalence of renal insufficiency and its relationship with mortality in cancer patients are unclear.We retrospectively studied 9465 patients with newly diagnosed cancer from January 2010 to December 2010. Renal insufficiency was defined as an estimated glomerular filtration rate (eGFR) cancer stage in the entire cohort, the corresponding hazard ratios were 1.87 (95% CI, 1.41-2.47) and 1.28 (95% CI, 1.01-1.62) for stage I to III and stage IV, respectively. However, this relationship was not observed after multivariate adjustment. Subgroup analysis found that eGFR cancer (adjusted HR 2.82, 95% CI [1.19-6.70]), but not in those with other cancer. Five hundred fifty-seven patients (6%) had proteinuria. When controlled for potential confounding factors, proteinuria was a risk factor for all-cause mortality among patients in the entire cohort, regardless of cancer stage and eGFR values. When patients were categorized by specific cancer type, the risk of all-cause death was only significant in patients with digestive system cancer (adjusted HR, 1.85 [1.48-2.32]).The prevalence of renal dysfunction was common in patients with newly diagnosed cancer.

    2011-01-01

    Full Text Available Multiple myeloma is an incurable plasma cell malignancy that is often accompanied by renal failure; there are a number of potential causes of this, of which cast nephropathy is the most important. Renal failure is highly significant in myeloma, as patient survival can be stratified by the severity of the renal impairment. Consequently, there is an ongoing focus on the pathological basis of cast nephropathy and the optimal treatment regimens in this setting, including effective chemotherapy regimens to reduce light chain production and emerging extracorporeal techniques to remove circulating light chains. This paper bridges recent advances in the pathogenesis and management of cast nephropathy in multiple myeloma.

    Survival, growth, and response to chemotherapy of cancer cells depends strongly on the interaction of cancer cells with the tumor microenvironment. In multiple myeloma, a cancer of plasma cells that localizes preferentially in the bone marrow, the microenvironment is highly enriched with myeloid cells. The majority of myeloid cells are represented by mature and immature neutrophils. The contribution of the different myeloid cell populations to tumor progression and chemoresistance in multiple myeloma is discussed.

    This International Myeloma Working Group consensus updates the disease definition of multiple myeloma to include validated biomarkers in addition to existing requirements of attributable CRAB features (hypercalcaemia, renal failure, anaemia, and bone lesions). These changes are based on the identification of biomarkers associated with near inevitable development of CRAB features in patients who would otherwise be regarded as having smouldering multiple myeloma. A delay in application of the label of multiple myeloma and postponement of therapy could be detrimental to these patients. In addition to this change, we clarify and update the underlying laboratory and radiographic variables that fulfil the criteria for the presence of myeloma-defining CRAB features, and the histological and monoclonal protein requirements for the disease diagnosis. Finally, we provide specific metrics that new biomarkers should meet for inclusion in the disease definition. The International Myeloma Working Group recommends the implementation of these criteria in routine practice and in future clinical trials, and recommends that future studies analyse any differences in outcome that might occur as a result of the new disease definition.

    The first S3 guidelines on renal cell cancer cover the practical aspects of imaging, diagnostics and therapy as well as the clinical relevance of pathology reporting. This review summarizes the changes in renal tumor classification and the new recommendations for reporting renal cell tumors. The S3 guidelines recommend the 2016 World Health Organization (WHO) classification of renal cell tumors. Novel renal cell tumor entities and provisional or emerging renal cell tumor entities of the 2016 WHO classification of renal tumors are discussed. The S3 guidelines for renal cell cancer also recommend the use of the WHO/International Society of Urologic Pathology (ISUP) grading system for clear cell and for papillary renal cell carcinomas, which replaces the previously used Fuhrman grading system.

    Mass spectrometry-based phosphoproteomics provides a unique unbiased approach to evaluate signaling network in cancer cells. The tyrosine kinase inhibitor sunitinib is registered as treatment for patients with renal cell cancer (RCC). We investigated the effect of sunitinib on tyrosine phosphorylation in RCC tumor cells to get more insight in its mechanism of action and thereby to find potential leads for combination treatment strategies. Sunitinib inhibitory concentrations of proliferation (IC50) of 786-O, 769-p and A498 RCC cells were determined by MTT-assays. Global tyrosine phosphorylation was measured by LC-MS/MS after immunoprecipitation with the antiphosphotyrosine antibody p-TYR-100. Phosphoproteomic profiling of 786-O cells yielded 1519 phosphopeptides, corresponding to 675 unique proteins including 57 different phosphorylated protein kinases. Compared to control, incubation with sunitinib at its IC50 of 2 µM resulted in downregulation of 86 phosphopeptides including CDK5, DYRK3, DYRK4, G6PD, PKM and LDH-A, while 94 phosphopeptides including Axl, FAK, EPHA2 and p38α were upregulated. Axl- (y702), FAK- (y576) and p38α (y182) upregulation was confirmed by Western Blot in 786-O and A498 cells. Subsequent proliferation assays revealed that inhibition of Axl with a small molecule inhibitor (R428) sensitized 786-O RCC cells and immortalized endothelial cells to sunitinib up to 3 fold. In conclusion, incubation with sunitinib of RCC cells causes significant upregulation of multiple phosphopeptides including Axl. Simultaneous inhibition of Axl improves the antitumor activity of sunitinib. We envision that evaluation of phosphoproteomic changes by TKI treatment enables identification of new targets for combination treatment strategies.

    Seventeen nickel compounds were administered to Fischer-344 rats (N = 270) by intrarenal injection (7 mg Ni/rat); the compounds included nickel sulfides, selenides, arsenides, oxide, antimonide, telluride, titanate, ferronickel alloy and metallic nickel dust. Erythrocytosis, as defined by peak hematocrit values that averaged greater than 55% during 1-4 months post-injection, occurred in nine of 17 Ni-treated groups (NiS2, beta NiS, alpha Ni3S2, Ni4FeS4, NiSe, Ni3Se2, NiAsS, NiO, Ni dust). Renal cancers (N = 23) developed within 2 years post-injection in nine of 17 Ni-treated groups (NiS2, beta NiS, alpha Ni3S2, Ni4FeS4, NiSe, Ni3Se2, NiAsS, NiAs, NiFe alloy). The renal cancers included eight fibrosarcomas, five mesangial cell sarcomas, two renal cell carcinomas, two carcinosarcomas, two leiomyosarcomas, two undifferentiated sarcomas, one rhabdomyosarcoma and one nephroblastoma. No erythrocytosis or renal cancers occurred in control rats (N = 97) in three groups treated with the vehicles or metallic iron dust. Rank correlation (p less than 0.0001) was observed between the incidences of erythrocytosis and renal cancers in the 17 Ni-treated groups. Rank correlation (p less than 0.001) was observed between the present incidences of renal cancers and the sarcoma incidences previously reported following intramuscular administration of the 17 nickel compounds to Fischer-344 rats (14 mg Ni/rat). The incidences of renal cancer were not correlated with the mass-fractions of nickel in the 17 compounds, the dissolution half-times of the compounds in rat serum or renal cytosol, or the phagocytic indices of the compounds in rat peritoneal macrophages.

    Full Text Available Renal medullary cancer is a rare malignancy almost exclusively seen in young patients of African ethnicity. These patients often present with the cardinal symptoms of hematuria, flank pain, and an abdominal mass, and this malignancy has been associated with patients carrying sickle cell trait. It is estimated that 300 million people worldwide carry sickle cell trait, and the presence of hematuria in these patients should be treated as a harbinger of a possible malignancy. Notably, this tumor mostly develops on the right side of the body. Patients often present with it at an advanced stage and the prognosis is poor. Therefore, a high index of suspicion in a patient of African descent presenting with a right sided abdominal mass and hematuria may assist in an early diagnosis. Current chemotherapy options are very limited, and early detection may provide a chance for surgical resection. It may also provide a bigger time frame for the initiation of novel chemotherapy regimens in patients who fail current chemotherapy regimens.

    Full Text Available Renal cancer (RC is one of the most frequent diseases in oncological urology; the most common form of RC is the clear cell carcinoma. However, percentage of less-studied non-clear cell RC (nccRC reaches up to 25 % of cases suggesting further studying, improvement of diagnosis and treatment of these tumors. The key events of carcinogenesis are genetic alterations including chromosomal aberrations and point mutations in proto-oncogenes and tumor suppressor genes. This review describes cytogenetic aberrations in the context of nccRC diversity according to the current ISUP classification. Translocation variants of nccRC (MiT-RC were characterized separately as particular cases of the chromosome rearrangements involving MiT gene family (TFE3, TFEB, MITF. In addition, the main nccRC hereditary forms caused by germinal mutations in the genes FLCN, FH, and MET, as well as recent studies of sporadic tumors with using the next generation sequencing techniques were reviewed. These experiments were designed to search for somatic mutations throughout the tumor genome or exom and revealed the different mutational profiles of I/II papillary RC subtypes, chromophobe carcinoma versus oncocytoma. The review may be informative for oncologists, urologists, geneticists and specialists in related sciences.

    Human BCCIP, a protein which interacts with BRCA2 and CDKN1A (Cip1, p21), has been implicated in many cellular processes including cell cycle regulation, DNA recombination and damage repair, telomere maintenance, embryonic development and genomic stability. BCCIP gene expression, which is an important BRCA2 cofactor in tumor suppression, has been identified in some primary cancers. Thus, we investigated the role of BCCIP expression in a large sample of clinically diagnosed primary ovarian cancer, renal cell carcinoma (RCC) and colorectal cancer (CRC) tissues. Using clinically diagnosed frozen primary cancer tissues, quantitative PCR (qPCR), western blot analysis (WB) and immunohistochemical staining (IHC) approaches were used to detect and measure gene expression. Reduced BCCIP gene expression in ovarian cancer, RCC and CRC tissues occurred in 74, 89 and 75% of tissue samples, respectively. qPCR analysis of mRNA expression in 54 ovarian cancer, 50 RCC and 44 CRC samples revealed significant (>2-fold decreased) BCCIP downregulation in 56, 70 and 46% of tissue samples, respectively. Although BCCIP expression in three different tumor tissues decreased, the relationship between BCCIP expression and clinicopathological features of each cancer was distinct. Compared to normal tissues, BCCIP expression in ovarian cancers was significantly downregulated in serous, endometrioid and mucinous carcinomas. Downregulation of BCCIP expression was strongly associated with clear cell RCC (ccRCC) and Fuhrman tumor grading, but significant differences in BCCIP expression between CRC and matched normal tissues occurred only in male CRC tissues (ptissue with a T4 tumor stage (ptissue samples (phuman ovarian cancer, RCC and CRC tissues, suggesting a role for the gene in the pathogenesis of these cancers.

    Silbermann, Rebecca; Roodman, G. David

    2013-01-01

    Multiple myeloma bone disease is marked by severe dysfunction of both bone formation and resorption and serves as a model for understanding the regulation of osteoblasts (OBL) and osteoclasts (OCL) in cancer. Myeloma bone lesions are purely osteolytic and are associated with severe and debilitating bone pain, pathologic fractures, hypercalcemia, and spinal cord compression, as well as increased mortality. Interactions within the bone marrow microenvironment in myeloma are responsible for the abnormal bone remodeling in myeloma bone disease. Myeloma cells drive bone destruction that increases tumor growth, directly stimulates the OCL formation, and induces cells in the marrow microenvironment to produce factors that drive OCL formation and suppress OBL formation. Factors produced by marrow stromal cells and OCL promote tumor growth through direct action on myeloma cells and by increasing angiogenesis. Current therapies targeting MMBD focus on preventing osteoclastic bone destruction; however regulators of OBL inhibition in MMBD have also been identified, and targeted agents with a potential anabolic effect in MMBD are under investigation. This review will discuss the mechanisms responsible for MMBD and therapeutic approaches currently in use and in development for the management of MMBD. PMID:26909272

    Multiple myeloma is incurable once osteolytic lesions have seeded at skeletal sites, but factors mediating this deadly pathogenic advance remain poorly understood. Here, we report evidence of a major role for the cell adhesion molecule CD166, which we discovered to be highly expressed in multiple myeloma cell lines and primary bone marrow cells from patients. CD166(+) multiple myeloma cells homed more efficiently than CD166(-) cells to the bone marrow of engrafted immunodeficient NSG mice. CD166 silencing in multiple myeloma cells enabled longer survival, a smaller tumor burden, and less osteolytic lesions, as compared with mice bearing control cells. CD166 deficiency in multiple myeloma cell lines or CD138(+) bone marrow cells from multiple myeloma patients compromised their ability to induce bone resorption in an ex vivo organ culture system. Furthermore, CD166 deficiency in multiple myeloma cells also reduced the formation of osteolytic disease in vivo after intratibial engraftment. Mechanistic investigation revealed that CD166 expression in multiple myeloma cells inhibited osteoblastogenesis of bone marrow-derived osteoblast progenitors by suppressing Runx2 gene expression. Conversely, CD166 expression in multiple myeloma cells promoted osteoclastogenesis by activating TRAF6-dependent signaling pathways in osteoclast progenitors. Overall, our results define CD166 as a pivotal director in multiple myeloma cell homing to the bone marrow and multiple myeloma progression, rationalizing its further study as a candidate therapeutic target for multiple myeloma treatment.

    Type 1 iodothyronine deiodinase (DIO1) regulates peripheral metabolism of thyroid hormones that control cellular proliferation, differentiation and metabolism. The significance of DIO1 in cancer is unknown. In this study we hypothesized that diminished expression of DIO1, observed in renal cancer, contributes to the carcinogenic process in the kidney. Here, we demonstrate that ectopic expression of DIO1 in renal cancer cells changes the expression of genes controlling cell cycle, including cyclin E1 and E2F5, and results in inhibition of proliferation. The expression of genes encoding collagens (COL1A1, COL4A2, COL5A1), integrins (ITGA4, ITGA5, ITGB3) and transforming growth factor-β-induced (TGFBI) is significantly altered in renal cancer cells with induced expression of DIO1. Finally, we show that overexpression of DIO1 inhibits migration of renal cancer cells. In conclusion, we demonstrate for the first time that loss of DIO1 contributes to renal carcinogenesis and that its induced expression protects cells against cancerous proliferation and migration.

    Renal transplant patients have high risk for bladder cancer. The reactivation of BK virus is common in renal transplant patients especially in the urinary tract. There was some evidence suggesting that the reactivation of BK virus (BKV) in renal transplant patients may associate with the development of bladder cancer. Here we demonstrated that a patient that had persistent elevated BKV viruria (urine BKV DNA concentration more than 10(11) copies/ml) after renal transplantation. Then, bladder cancer was found in 13 months after kidney transplantation. The urine BKV DNA concentration was detected by real-time PCR and the BKV DNA in the bladder tumor was detected by PCR. BKV DNA was found in the marginal and central part of the bladder tumor. After removal of the bladder cancer, the urine BKV viral load in this patients dropped dramatically to <10(2) copies/ml. However, the urine viral load had increased modestly to 10(6) copies/ml in 3 months after surgery. Since there is a close correlation between the urine BK viral load and the presence of bladder cancer, we suggested that there might be a causal relationship between the reactivation of BKV and the development of bladder cancer in renal transplant patient.

    This update provides new insights into the biology, diagnosis, prognosis, and treatment of multiple myeloma (MM) and its complications. In Section I, Drs. John Shaughnessy, Jr., and Bart Barlogie first correlate global gene microarray expression profiling of patient MM samples with normal plasma cells to provide the basis for a developmental stage-based classification of MM. The powerful clinical utility of these analyses is illustrated in delineating mechanism of drug action, identifying novel therapeutic targets, and providing a molecular analysis not only of the tumor cell, but also of the tumor microenvironment, in MM. In Section II, Dr. Jean-Luc Harousseau reviews the rationale and current results of high dose therapy and autologous stem cell transplantation in MM, including optimal patient selection, prognostic factors, conditioning regimens, sources of stem cells, use of tandem transplantation, and maintenance therapy. He then provides an update on the results of allotransplantation approaches in MM, focusing on proposed methods to reduce toxicity and exploit the graft-versus-MM alloimmune effect by transplantation earlier in the disease course, T cell depletion, and nonmyeloablative transplantation. In Section III, Dr. G. David Roodman provides recent insights into the mechanisms of osteoclast activation, interactions between bone and MM cells, adhesive interactions in MM bone disease, and osteoblast suppression. These recent advances not only provide insights into pathogenesis of MM bone disease, but also form the framework for novel therapeutics. In Section IV, Dr. Kenneth Anderson provides an up-to-date discussion of the role of the bone marrow microenvironment in promoting growth, survival, drug resistance, and migration of MM cells and the signaling cascades mediating these sequelae. These studies provide the framework for evaluation of novel therapeutics targeting the MM cell-host interaction in vivo in animal models and in derived clinical trials.

    Anticancer drug efficiency is governed by its bioavailability. In order to increase this parameter, we synthesized several injectable and biodegradable systems based on incorporation of anti-estrogens (AEs) in nanoparticles (NPs) and liposomes were synthesized. Both nanospheres (NS) and nanocapsules (NCs, polymers with an oily core in which AEs were solubilized) incorporated high amounts of 4-hydroxy-tamoxifen (4-HT) or RU 58668 (RU). Physico-chemical and biological parameters of these delivery systems, and coupling of polyethylene-glycol chains on the NP surface revealed to enhance the anti-tumoral activity of trapped AEs in a breast cancer MCF-7 cell xenograft model and to induce apoptosis. These features correlated with an augmentation of p21(Waf-1/Cip1) and of p27(Kip1) and a concomitant decrease of cyclin D1 and E in tumor extracts. Liposomes containing various ratios of lipids enhanced the apoptotic activity of RU in several multiple myeloma (MM) cell lines tested by flow cytometry. MM cell lines expressed both estrogen receptor alpha and beta subtypes except Karpas 620. Karpas 620 cells which did not respond to AEs became responsive following ER cDNA transfection. A new MM xenograft model was generated after s.c. injection of RPMI 8226 cells in nude mice. RU-loaded liposomes, administered i.v. in this model, at a dose of 12mgRU/kg/week, induced the arrest of tumor growth contrary to free RU or to empty liposomes. Thus, the drug delivery of anti-estrogens enhances their ability to arrest the growth of tumors which express estrogen receptors and are of particular interest for estrogen-dependent breast cancer treatment. In addition it represents a new potent therapeutic approach for multiple myeloma.

    Lithium induces proliferation in the epithelium of renal collecting ducts. A recent small-scale cohort study reported a strong association between use of lithium and increased risk of renal neoplasia. We therefore conducted a large-scale pharmacoepidemiologic study of the association between long-term use of lithium and risk of upper urinary tract cancer, including renal cell cancer and cancers of the renal pelvis or ureter. We identified all histologically verified upper urinary tract cancer cases in Denmark between 2000 and 2012 from the Danish Cancer Registry. A total of 6477 cases were matched by age and sex to 259,080 cancer-free controls. Data on lithium use from 1995 to 2012 were obtained from the Danish Prescription Registry. We estimated the association between long-term use of lithium (≥5 years) and risk of upper urinary tract cancer using conditional logistic regression with adjustment for potential confounders. Long-term use of lithium was observed among 0.22% of cases and 0.17% of controls. This yielded an overall nonsignificant adjusted odds ratio (OR) of 1.3 (95% confidence interval [95% CI], 0.8-2.2) for upper urinary tract cancer associated with long-term use of lithium. Analyses stratified by stage and subtype of upper urinary tract cancer revealed slight but nonsignificant increases in the ORs for localized disease (OR, 1.6; 95% CI, 0.8-3.0) and for renal pelvis/ureter cancers (OR, 1.7; 95% CI, 0.5-5.4). In conclusion, in our nationwide case-control study, use of lithium was not associated with an increased risk of upper urinary tract cancer.

    There has been expansion of therapeutic options in the management of metastatic renal cell carcinoma due to a better knowledge of the molecular biology of kidney cancers. There are different tumors grouped under the term renal cell carcinoma, being clear cell cancer the most frequent and accounting for 80% of kidney tumors. Mutations in the Von Hippel-Lindau gene can be identified in up to 80% of sporadic clear cell cancer, linking a genetically inheritable disease where vascular tumors are frequent, with renal cell cancer. Other histologic types present specific alterations in molecular pathways, like c-MET in papillary type I tumors, and Fumarase Hydratase in papillary type II tumors. Identification of the molecular alteration for a specific tumor may offer an opportunity for treatment selection based on biomarkers, and, in the future, for developing an engineering designed genetic treatment.

    Previous studies have demonstrated that the benzo[c]phenanthridine alkaloid chelerythrine chloride (CC) has inhibitory effects on various tumors. However, the anticancer activity of CC and its underlying mechanisms have not been elucidated in renal cancer cells. The present study examined the effects of CC on growth inhibition and apoptosis of renal cancer cells in vitro and in vivo. Flow cytometry and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assays revealed that CC markedly suppressed the growth of HEK-293 and human renal cancer SW-839 cells in a time- and dose-dependent manner. The xenograft mouse model, which was performed in nude mice, exhibited a reduced tumor growth following CC treatment. In addition, the present study revealed that CC significantly decreased the phosphorylation of extracellular signal-regulated kinase (ERK) and Akt, which was accompanied by upregulation of p53, B-cell lymphoma 2 (Bcl-2)-associated X protein, cleaved caspase-3 and cleaved poly (adenosine diphosphate-ribose) polymerase (PARP), and downregulation of Bcl-2, caspase-3 and PARP. Furthermore, the use of PD98059, a specific mitogen-activated protein kinase kinase inhibitor, potentiated the proapoptotic effects of CC, which indicated that CC may induce apoptosis in renal cancer cells partly via inhibition of ERK activity. Overall, the results of the present study demonstrated that CC may be developed as a potential anticancer treatment for patients with renal cancer.

    The expression level of suppressor of cytokine signaling-3(SOCS-3) in human renal carcinoma and its methylation state were investigated. Reverse transcription-polymerase chain reaction(RT-PCR), immuocytochemistry,immunohistochemistry and Western blot were used to detect the expression level of SOCS-3, and the methylation of SOCS gene was investigated by methylation specific PCR in the tissues of i 5 cases of renal carcinoma. Compared to those of the normal renal cell line and specimens, the expression level of SOCS-3 in renal carcinoma was significantly lower or can't be detected(P<0.01). And the methylation of SOCS-3 gene in the tissue of renal carcinoma was significantly higher. The expression of SOCS-3 gene is significantly lower in renal carcinoma and the high methylation of the promoter island of SOCS-3 gene is associated with the lower expression of SOCS-3 gene. It may be one of main mechanisms for the development and progress of renal carcinoma.

    Full Text Available Multiple myeloma is an incurable disease, although patient survival has increased with the availability of novel agents. Both multiple myeloma and its therapies often affect the renal, immune, skeletal, hematologic, and nervous systems. The resulting organ dysfunctions often impair the quality of life of affected patients, complicate and limit subsequent therapies, and may result in significant mortality. Research on the treatment of complications of multiple myeloma has been limited; hence, preventative and management strategies for patients with these complications are heterogeneous and often based on anecdotal experience. In this paper, we review the effects of myeloma and the novel therapies on organ systems and suggest management strategies.

    The treatment of advanced renal cell carcinoma has posed a challenge for decades, in part because of common themes related to intrinsic resistance to cytotoxic chemotherapy and the obscure biology of these cancer types. Forward movement in the treatment of the renal cell carcinomas thus can be approached in 2 ways: by splitting the tumor types along histologic and molecular features, in the hopes of coupling highly precision-focused therapy on a subset of patients who have disease with the most potential for benefit; or by lumping the various biologies and histologies together, to include the rarer renal cell carcinoma types with the more common types. The former strategy satisfies the desire for customized precision in treatment delivery, whereas the latter strategy allows clinicians to offer a wider therapeutic menu in a set of diseases we are continuing to learn about on a physiologic and molecular level.

    This study aimed to explore the invasion and metastasis ability of miR-141 in 786-0 renal cancer tissue cells, as well as identify the key function of endogenous miR-141 in adjustment and control of malignant activities of renal cancer. The renal cancer cell strain with overexpression of miR-141 and its control renal cancer cell line were constructed; methyl thiazolyl tetrazolium (MTT) assay was adopted to measure proliferation of renal cancer cells; Transwell assay was performed to measure the invasion and metastasis ability of cells; MTT assay and fluorescence activated cell sorting (FACS) were used for measurement of cell apoptosis and drug susceptibility. Results indicated that the expression of miR-141 in 786-0 cells could be significantly increased 400-fold by slow viruses that contained miR-141; moreover, c omprehensive functions showed that miR-141 inhibited the invasion and metastasis ability of renal cancer cells to a great extent (p less than 0.001), partially inhibited cell growth (p less than 0.05) and also induced cell cycle to be arrested in G0/G1 as well as reducing the number of cells in S phase (DNA replicative phase). Moreover, miR-141 could not induce morphologic changes of renal cancer cells, had no direct stimulating effect on cell apoptosis and could not improve the drug susceptibility of renal cancer cells to drugs such as cis-Dichlorodiamineplatinum (DDP), 5-fluorouracil (5-FU) and tumor-related apoptosis-inducing ligand (TRAIL). In conclusion, miR-141 can be considered an important cancer suppressor gene of renal cancer by inhibiting proliferation and metastasis of renal cancer cells.

    Computer-aided histological image classification systems are important for making objective and timely cancer diagnostic decisions. These systems use combinations of image features that quantify a variety of image properties. Because researchers tend to validate their diagnostic systems on specific cancer endpoints, it is difficult to predict which image features will perform well given a new cancer endpoint. In this paper, we define a comprehensive set of common image features (consisting of 12 distinct feature subsets) that quantify a variety of image properties. We use a data-mining approach to determine which feature subsets and image properties emerge as part of an "optimal" diagnostic model when applied to specific cancer endpoints. Our goal is to assess the performance of such comprehensive image feature sets for application to a wide variety of diagnostic problems. We perform this study on 12 endpoints including 6 renal tumor subtype endpoints and 6 renal cancer grade endpoints. Keywords-histology, image mining, computer-aided diagnosis.

    Full Text Available Introduction: Multiple myeloma is defined as a malignant proliferation of a single clone of plasma cells typically accompanied by the secretion of monoclonal immunoglobulins that are detectable in the serum or urine. The most common clinical manifestations of symptomatic multiple myeloma are anaemia, infections, lytic or osteopenic bone disease, or renal failure. Renal impairment is present in 50% of patients at diagnosis and its most common cause is cast nephropathy (63 to 87%. The aim of this study is to clarify the clinical, biological and prognosis parameters in patients with renal impairment multiple myeloma, study the different mortality factors and focus on the economic impacts that present these patients within the renal unit and hospital. Material and Methods: This is a retrospective study of MM with renal impairment cases admitted at the nephrology department of the FEZ university hospital in a period extended from January 2010 to December 2011. The diagnosis is based on Southwest Oncology Group criteria (SWOG and CRAB activity criteria. The outcome is evaluated according to the criteria of the International Myeloma Workings Group. Results:32 myeloma patients were enrolled for a total of 1250 admissions during a period of two years with 15 women and 17 men. The mean age is 59 ± 10 years. 81 % had impaired general condition and bone pain. 88% of cases had anemia including 1 patient with neutropenia, the acute kidney injury was found in 71%% of cases, the need for dialysis was required in 25% of patients. The monoclonal peak is observed in all patients who presented in immunofixation: Ig G 57% of cases and Ig A in 28% of cases. Monoclonal plasma cell infiltration>30% occurs in 50% of cases. The cast nephropathy myeloma is sustained in 53%% of cases. The kidney biopsy is performed in 6 patients and concluded for a myeloma tubulopathy in 2 patients and amylosis in 2 patients. All patients enrolled in our series applied for diagnosis

    Cucurbitacin B (CuB), a triterpenoid compound isolated from the stems of Cucumis melo, has long been used to treat hepatitis and hepatoma in China. Although its remarkable anti-cancer activities have been reported, the mechanism by which it achieves this therapeutic activity remains unclear. This study was designed to investigate the molecular mechanisms by which CuB inhibits cancer cell proliferation. Our results indicate that CuB is a novel inhibitor of Aurora A in multiple myeloma (MM) cells, arresting cells in the G2/M phase. CuB also inhibited IL-10-induced STAT3 phosphorylation, synergistically increasing the anti-tumor activity of Adriamycin in vitro. CuB induced dephosphorylation of cofilin, resulting in the loss of mitochondrial membrane potential, release of cytochrome c, and activation of caspase-8. CuB inhibited MM tumor growth in a murine MM model, without host toxicity. In conclusion, these results indicate that CuB interferes with multiple cellular pathways in MM cells. CuB thus represents a promising therapeutic tool for the treatment of MM. PMID:27418139

    2012-01-01

    Multiple myeloma is the second most common hematological malignancy and the most frequent cancer to involve the skeleton. Multiple myeloma bone disease (MMBD) is characterized by abnormal bone remodeling with dysfunction of both bone resorption and bone formation, and thus can be used as a paradigm for other inflammatory bone diseases, and the regulation of osteoclasts and osteoblasts in malignancy. Studies of MMBD have identified novel regulators that increase osteoclastogenesis and osteoclast function, repress osteoblast differentiation, increase angiogenesis, or permanently alter stromal cells. This review will discuss the current understanding of mechanisms of osteoclast and osteoblast regulation in MMBD, and therapeutic approaches currently in use and under development that target mediators of bone destruction and blockade of bone formation for myeloma patients, including new anabolic therapies.

    The renal cell carcinoma is the ninth most common cancer with an increasing occurrence and mortality. Recoverin is the first retina-specific photoreceptor protein that was shown to undergo aberrant expression, due to its promoter demethylation, as a cancer-retina antigen in a number of malignant tumors. In this work, we demonstrated that recoverin is indeed expressed in 68.4 % of patients with different subtypes of renal cell carcinoma, and this expression has tendency to correlate with tumor size. Interestingly, 91.7 % of patients with the benign renal tumor, oncocytoma, express recoverin as well in their tumor. Epigenetic analysis of the recoverin gene promoter revealed a stable mosaic methylation pattern with the predominance of the methylated state, with the exception of -80 and 56 CpG dinucleotides (CpGs). While the recoverin expression does not correlate withoverall survival of the tumor patients, the methylation of the recoverin gene promoter at -80 position is associated with better overall survival of the patients. This work is the first report pointing towards the association of overall survival of renal cell carcinoma (RCC) patients with promoter methylation of a cancer-retina antigen. Taken together, these data allow to consider recoverin as a potential therapeutic target and/or marker for renal tumors.

    Full Text Available The paper gives the results of studying the urinary levels of markers of acute kidney injury (AKI in 46 patients with renal cancer during separate ureteral catheterization before the surgery and 24 hours after laparoscopic partial nephrectomy performed due to elective indications under warm ischemia. The levels of cystatin C, neutrophil gelatinase-associated lipocalin (NGAL, liver-type fatty acid-binding protein (L-FABP, and interleukin-18 were examined by enzyme immunoassay. It has been established that the risk of early postoperative AKI may be predicted from the baseline urinary levels of cystatin C and LFABP in patients with renal cancer resulting from 15-20-min warm ischemia time during the partial nephrectomy. An approach based on estimation of the baseline urinary levels of cystatin C and L-FABP to be incorporated into a preoperative examination scheme is proposed for surgical treatment policy choosing in patients with renal cancer. A scheme for examining patients with renal cancer is also suggested for the risk of complications and the degree of AKI assessing in the early post-operative period.

    Multiple myeloma is the most common cause of death of hematological malignancy worldwide. Cullin 4A has been proposed as oncogene in several types of human cancer, but the expression and function of cullin 4A in multiple myeloma remain unclear. Here, we demonstrate that cullin 4A plays an oncogenic role in multiple myeloma development. The expression of cullin 4A was detected by quantitative real-time polymerase chain reaction in multiple myeloma patients and multiple myeloma cell lines. In addition, silencing of cullin 4A with small interfering RNA was performed in human multiple myeloma cells, and the impact on proliferation, cell cycle, apoptosis, migration, and invasion of the multiple myeloma cells was analyzed. We found that the level of cullin 4A in serum samples was significantly upregulated in patients with multiple myeloma compared with healthy control subjects. Knockdown of cullin 4A via small interfering RNA inhibited the proliferation of the multiple myeloma cell lines by delaying cell-cycle progression and increasing apoptosis. cullin 4A downregulation inhibited multiple myeloma cell migration and invasion in vitro. Our results suggested that cullin 4A could be a promising therapy target in multiple myeloma patients.

    Full Text Available Abstract Background Many adjuvant trials have been undertaken in an attempt to reduce the risk of recurrence among patients who undergo surgical resection for locally advanced renal cancer. However, no clear benefit has been identified to date. This systematic review was conducted to examine the exact role of adjuvant therapy in renal cancer setting. Methods Randomized controlled trials were searched comparing adjuvant therapy (chemotherapy, vaccine, immunotherapy, biochemotherapy versus no active treatment after surgery among renal cell cancer patients. Outcomes were overall survival (OS, disease-free survival (DFS, and severe toxicities. Risk ratios (RR, hazard ratios (HR and 95% confidence intervals were calculated using a fixed-effects meta-analysis. Heterogeneity was measured by I2. Different strategies of adjuvant treatment were evaluated separately. Results Ten studies (2,609 patients were included. Adjuvant therapy provided no benefits in terms of OS (HR 1.07; 95%CI 0.89 to 1.28; P = 0.48 I2 = 0% or DFS (HR 1.03; 95%CI 0.87 to 1.21; P = 0.77 I2 = 15% when compared to no treatment. No subgroup analysis (immunotherapy, vaccines, biochemotherapy and hormone therapy had relevant results. Toxicity evaluation depicted a significantly higher frequency of serious adverse events in the adjuvant group. Conclusions This analysis provided no support for the hypothesis that the agents studied provide any clinical benefit for renal cancer patients although they increase the risk of toxic effects. Randomized trials are underway to test targeted therapies, which might open a new therapeutic frontier. Until these trials yield results, no adjuvant therapy can be recommended for patients who undergo surgical resection for renal cell cancer.

    We aimed to evaluate the cancer detection rates of 6-, 10-, 12-core biopsy regimens and the optimal biopsy protocol for prostate cancer diagnosis in patients with renal failure. A total of 122 consecutive patients with renal failure underwent biopsy with age-specific prostate-specific antigen (PSA) levels up to 20 ng/mL. The 12-core biopsy technique (sextant biopsy + lateral base, lateral mid-zone, lateral apex, bilaterally) performed to all patients. Pathology results were examined separately for each sextant, 10-core that exclude parasagittal mid-zones from 12-cores (10a), 10-core that exclude apex zones from 12-cores (10b) and 12-core biopsy regimens. Of 122 patients, 37 (30.3%) were positive for prostate cancer. The cancer detection rates for sextant, 10a, 10b and 12 cores were 17.2%, 29%, 23.7% and 30.7%, respectively. Biopsy techniques of 10a, 10b and 12 cores increased the cancer detection rates by 40%, 27.5% and 43.2% among the sextant technique, respectively. Biopsy techniques of 10a and 12 cores increased the cancer detection rates by 17.1% and 21.6% among 10b biopsy technique, respectively. There were no statistical differences between 12 core and 10a core about cancer detection rate. Adding lateral cores to sextant biopsy improves the cancer detection rates. In our study, 12-core biopsy technique increases the cancer detection rate by 5.4% among 10a core but that was not statistically different. On the other hand, 12-core biopsy technique includes all biopsy regimens. We therefore suggest 12-core biopsy or minimum 10-core strategy incorporating six peripheral biopsies with elevated age- specific PSA levels up to 20 ng/mL in patients with renal failure.

    Full Text Available Abstract A case of leptomeningeal carcinomatosis in a patient with known brain and lung metastases from renal cell cancer without previous systemic therapy is presented. Neoplastic meningitis (NM developed 31 months after first diagnosis of simultaneous extra- and intracranial recurrence of kidney cancer and surgical resection of a cerebellar metastasis. In spite of local radiotherapy to the macroscopic NM lesions in the cervical and lumbar spine followed by initiation of sunitinib, the patient succumbed to his disease 4 months after the diagnosis of NM. The untreated lung metastases progressed very slowly during almost 3 years of observation. This case illustrates important issues around both biological behaviour and treatment approaches in metastatic renal cell cancer.

    To discuss the curative effects of laparoscopy partial nephrectomy (LPN) combined with laparoscopy cryoablation (LCA) in treating renal cancer. A total of 58 patients that were diagnosed with phase III-IV renal cancer in the Hospital from February 2013 to October 2014 were enrolled in this study. After obtaining the approval of Ethics Committee of the Hospital as well as the informed consent of the patients and their relatives, the patients were randomly divide into two groups: control group consisted of 24 patients, who were treated with LPN + chemo radiotherapy and the observation group consisted of 34 patients, who were treated with LPN in combination of LCA + chemo radiotherapy. The rate of successful operation was significantly higher in the observation group than in control group and the prevalence of per procedural complications in observation group was significantly lower than that of control group, and these differences had statistical significance (p LCA therapy was quite effective in treating with middle and advanced renal cancer. Compared with pure LPN therapy, LPN combined LCA therapy could significantly improve the surgical effects, retain the functions of the renal unit and improve the patients' prognosis.

    In Germany, renal cell cancer counts for 2.5 % of all carcinomas in women and 3.5 % in men. Curative therapy ensures good chances of recovery. But there might be permanent complications like renal insufficiency, pain, incisional hernia, flank muscle relaxation, and paresis. In addition, targeted therapy is associated with several potential side effects. In both therapy groups, severe psychological problems may occur. Still employed patients with these problems must be examined by an expert to estimate the possibilities of returning to working (positive scope of work) and occupations which can not be performed anymore (negative scope of work).

    ASBTARCT Adenoviruses mediated cancer gene therapies are widely investigated and show a promising effect on cancer treatment. However, efficient gene transfer varies among different cancer cell lines based on the expression of coxsakie adenovirus receptor (CAR). Hep27, a member of dehydrogenase/reductase (SDR) family, can bind to Mdm2, resulting in the attenuation of Mdm2-mediated p53 degradation. Here we constructed a fiber chimeric adenovirus carrying hep27 gene (F5/35-ZD55-Hep27), in which the fiber protein of 5-serotype adenovirus (Ad5) was substituted by that of 35-serotype adenovirus (Ad35), aiming to facilitate the infection for renal cancer cells and develop the role of hep27 in cancer therapy. We evaluated the CAR and CD46 (a membrane cofactor protein for Ad35) expression in four kinds of renal cancer cells and assessed the relationship between receptors and infection efficiency. 5/35 fiber-modified adenovirus had a much promising infectivity compared with Ad5-based vector in renal cancer cells. F5/35-ZD55-Hep27 had enhanced antitumor activity against human renal cancer cells compared to the other groups. Further, hep27 mediated p53 and cleaved-PARP upregulation and mdm2 downregulation was involved and caused increased apoptosis. Moreover, F5/35-ZD55-Hep27 significantly suppressed tumor growth in subcutaneous renal cancer cell xenograft models. Our data demonstrated that 5/35 fiber-modified adenovirus F5/35-ZD55-Hep27 transferred into renal cancers efficiently and increased p53 to induce cancer cell apoptosis. Thus 5/35 fiber-modified adenoviral vector F5/35-ZD55-Hep27 might a promising vector and antitumor reagent for renal cancer gene therapy.

    The present study was designed to obtain insights into guideline adherence regarding the use of expensive drugs in The Netherlands in daily practice and into the patients' perspective on the decision-making process. A retrospective review of medical charts regarding the use of trastuzumab in early and metastatic breast cancer (EBC/MBC) and bortezomib in multiple myeloma (MM) was conducted. Prescription according to clinical practice guidelines was assessed. The review was supplemented with patient interviews. Of 702 adjuvant-treated EBC patients, 97% had a documented human epidermal growth factor receptor 2 (HER2) testing (23% HER2 positive). 92% (147/160) of the HER2-positive EBC patients were treated with trastuzumab. Of 594 MBC patients, 81% had a documented HER2 testing (19% HER2 positive). 82% (75/91) of the HER2-positive MBC patients were treated with trastuzumab. Of 68 MM patients, 50% were treated with bortezomib. Reasons not to treat were consistent with the guidelines. Patients were generally satisfied with the decision-making process; improvements in patient education were suggested (e.g., repeating the information given, adding information on side effects). Guidelines were generally well followed with respect to trastuzumab and bortezomib, indicating that funding did not influence the treatment decisions of physicians. In view of the growing numbers of both cancer patients and expensive new anticancer drugs, and increasing budget constraints, it is unclear whether the present-day policies will guarantee a similar level of guideline adherence. Patient involvement in decision-making could be increased by improving the patient education on treatment. © 2016 S. Karger GmbH, Freiburg.

    Renal-cell carcinoma represents 95% of all renal tumours. The Von Hippel-Lindau (VHL) tumor-suppressor gene is mutated or silenced in most clear cell renal carcinomas. pVHL loss results in the stabilization of the heterodimeric transcription factor hypoxia-inducible factor (HIF) and enhanced transactivation of HIF target genes. HIF itself has been difficult to inhibit with drug-like molecules although a number of agents that indirectly inhibit HIF, including mTOR (mammalian target of rapamycin) inhibitors, have been identified. Moreover, a number of drugs have been developed that target HIF-responsive gene products, such as vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF), implicated in tumor angiogenesis. Many of these targeted therapies, especially sunitinib, have demonstrated significant activity in kidney cancer clinical trials and represent a substantive advance in the treatment of this disease.

    Renal cell carcinoma (RCC) is the most common malignancy in the kidney in the world, and the 5-year overall survival for patients remains poor due to the lack of effective treatment strategies. Although ABT-737, as a Bcl-2/Bcl-xL inhibitor, has recently emerged as a novel cancer therapeutic reagent, apoptosis induced by ABT-737 is often blocked in several types of cancer cells. This study investigated whether the combination of the small-molecule BH3 mimetic ABT-737 and the lysosome inhibitor chloroquine was an effective strategy for treating renal cancer cells. We found that the combination of ABT-737 and chloroquine synergistically decreased cell viability when compared to treatment with either single reagent. Cell apoptosis induced by a combined treatment was markedly inhibited by the caspase inhibitors z-DEVD-FMK and z-VAD-FMK. It was also inhibited by cathepsin inhibitor E-64 and CTSI (cathepsin inhibitor), which suggested that apoptosis was dependent on the cascade of caspase activation and cathepsins released from lysosomes. Furthermore, we found that ABT-737 could increase the cell level of ROS, which triggers cathepsin-mediated cell death and augments the role of chloroquine in cell death. So the combination of ABT-737 and chloroquine was an effective strategy for the treatment of renal cancer cells, and this combined strategy may widen the therapeutic window of ABT-737 and chloroquine as well as enhance the clinical efficacy of synergistic drug combinations.

    Glycogen synthase kinase-3 (GSK-3), a constitutively active serine/threonine kinase, is a key regulator of numerous cellular processes ranging from glycogen metabolism to cell cycle regulation and proliferation. Consistent with its involvement in many pathways, it has also been implicated in the pathogenesis of various human diseases including Type II diabetes, Alzheimer's disease, bipolar disorder, inflammation and cancer. Consequently it is recognized as an attractive target for the development of new drugs. In the present study, we investigated the effect of both pharmacological and genetic inhibition of GSK-3 in two different renal cancer cell lines. We have shown potent anti-proliferative activity of 9-ING-41, a maleimide-based GSK-3 inhibitor. The anti-proliferative activity is most likely caused by G0–G1 and G2-M phase arrest as evident from cell cycle analysis. We have established that inhibition of GSK-3 imparted a differentiated phenotype in renal cancer cells. We have also shown that GSK-3 inhibition induced autophagy, likely as a result of imbalanced energy homeostasis caused by impaired glucose metabolism. Additionally, we have demonstrated the antitumor activity of 9-ING-41 in two different subcutaneous xenograft RCC tumor models. To our knowledge, this is the first report describing autophagy induction due to GSK-3 inhibition in renal cancer cells. PMID:24327518

    Epidemiological, clinical, biochemical and genetic research has revealed that renal cell cancer (RCC) etiology is hormone-related. It was shown that hormone receptors are abnormally expressed in RCC cells. Abnormal endocrine stimulation also plays a significant role in RCC pathophysiology. Cellular proliferation, migration, angiogenesis, and drug resistance in RCC is modulated by para- and autocrine hormonal stimulation. In particular, RCC overexpression of gonadotropin-releasing hormone and its receptor was reported. On the contrary, corticotropin releasing hormone was reported to inhibit RCC cell proliferation and regulate angiogenesis. Overexpression of luteinizing hormone also promotes RCC tumor angiogenesis. Estrogen receptor α overexpression increases the transcriptional factor activity of hypoxia inducible factor HIF-1α, but estrogen receptor β has a cancer suppressive role. Glucocorticoid receptors and androgen receptor are markers of indolent RCC and assigned tumor suppressive activity. Proopiomelanocortin is upregulated in VHL-mutated renal cell carcinoma via Nur77 transcription factor signaling. In RCC, follicle-stimulating hormone receptor promotes angiogenesis and metastatic formation via VEGF release. Mineralocorticoid receptor overexpression promotes cell survival and increases RCC cell proliferation. Vitamin D receptor expression is downregulated or absent in RCC and differentiate subtypes of renal cell tumors. RAR-β promotes tumorigenesis but retinoic acid receptor γ expression correlates negatively with the TNM stage at diagnosis. Finally, progesterone receptor expression is negatively correlated with the cancer stage. Molecular data analysis revealed the possibility of renal cancer cell proliferation induction via hormone activated pathways. Inhibition of hormonal signaling may thus play a putative role in supportive therapies against this cancer type.

    2014-02-01

    Full Text Available Background: The finding of a renal mass on imaging is suggestive of metastatic non-small cell lung cancer in the presence of a lung tumor but can also have another origin. Case Report: We describe the case of a patient diagnosed with stage IV lung cancer based on a renal metastasis. A second opinion including review of histopathological data and additional imaging followed by lung surgery and cryoablation of the kidney lesion revealed two tumors of different origins, non-small cell lung cancer and a renal cell carcinoma. Discussion: The presence of a renal mass diagnosed on a CT scan in a patient with lung cancer is not always synonymous with metastatic disease. Confirmation of diagnosis by tissue sampling is mandatory, especially if a synchronous primary tumor is possible.

    Full Text Available Abstract Background Aberrant promoter hypermethylation of cancer-associated genes occurs frequently during carcinogenesis and may serve as a cancer biomarker. In this study we aimed at defining a quantitative gene promoter methylation panel that might identify the most prevalent types of renal cell tumors. Methods A panel of 18 gene promoters was assessed by quantitative methylation-specific PCR (QMSP in 85 primarily resected renal tumors representing the four major histologic subtypes (52 clear cell (ccRCC, 13 papillary (pRCC, 10 chromophobe (chRCC, and 10 oncocytomas and 62 paired normal tissue samples. After genomic DNA isolation and sodium bisulfite modification, methylation levels were determined and correlated with standard clinicopathological parameters. Results Significant differences in methylation levels among the four subtypes of renal tumors were found for CDH1 (p = 0.0007, PTGS2 (p = 0.002, and RASSF1A (p = 0.0001. CDH1 hypermethylation levels were significantly higher in ccRCC compared to chRCC and oncocytoma (p = 0.00016 and p = 0.0034, respectively, whereas PTGS2 methylation levels were significantly higher in ccRCC compared to pRCC (p = 0.004. RASSF1A methylation levels were significantly higher in pRCC than in normal tissue (p = 0.035. In pRCC, CDH1 and RASSF1A methylation levels were inversely correlated with tumor stage (p = 0.031 and nuclear grade (p = 0.022, respectively. Conclusion The major subtypes of renal epithelial neoplasms display differential aberrant CDH1, PTGS2, and RASSF1A promoter methylation levels. This gene panel might contribute to a more accurate discrimination among common renal tumors, improving preoperative assessment and therapeutic decision-making in patients harboring suspicious renal masses.

    Incidence rates of kidney cancer are thought to be highest in places situated at high latitudes and in populations with high intake of energy from animal sources. This suggests that low 25-hydroxyvitamin D status, due to lower levels of UVB irradiance, and energy from animal sources might be involved in etiology. The association of latitude with age-adjusted incidence rates was determined for all 175 countries in a UN cancer database, GLOBOCAN. The independent association of UVB irradiance, cloud cover and intake of calories from animal sources with age-adjusted incidence rates was assessed using multiple regression in 139 countries that provided dietary data. Renal cancer incidence rates were highest in countries situated at the highest latitudes, in men (R(2) = 0.64, p cancer incidence rates (p = 0.0003), while cloud cover (p = 0.003) and intake of calories from animal sources (p cancer.

    Full Text Available Abstract Wegener's granulomatosis (WG is a systemic disorder characterized by necrotizing vasculitis involving the respiratory tract, and in most cases, the kidneys. The most common manifestation of WG in the kidneys is segmental necrotizing glomerulonephritis. The presence of a renal mass as a manifestation of WG is rare. We report a patient with WG in whom a CT scan revealed an infiltrating mass in the lower portion of the left kidney. After surgical exploration, we performed an open radical nephrectomy. Histopathology showed clear cell type renal cell carcinoma (RCC. RCC associated with WG has been reported in only a few cases, and in most of them, the diseases started simultaneously, suggesting common pathogenetic pathways. Long-term immunosuppressive treatment is a known risk factor in the development of malignancies, so occurrence of RCC in WG has been proposed as a side effect of cyclophosphamide treatment. Furthermore, it is important to make a differential diagnosis between RCC and pseudotumors in WG as they cannot be distinguished solely on basis of imaging findings. Due to the higher risk of urologic malignancies, more frequent checkups and screening of WG patients should be considered.

    Radioiodine (RAI) is a cornerstone in the treatment of Differentiated Thyroid Cancer (DTC). In patients on haemodialysis due to End-Stage Renal Disease (ESRD), it must be used cautiously, considering the renal clearance of this radionuclide. Also, the safety of the procedure and subsequent long-term outcome is still not well defined. In 2001, we described a dosimetric method and short-term results in three patients, with a good safety profile. We hypothesize that our method is safe in a long-term scenario without compromising the prognosis of both renal and thyroid disease. Descriptive-retrospective study. A systematic search was carried out using our clinical database from 2000 to 2014. DTC and radioiodine treatment while on haemodialysis. peritoneal dialysis. Final sample n=9 patients (n=5 males), age 48 years (median age 51 years males, 67 years female group); n=8 papillary thyroid cancer, n=1 follicular thyroid cancer; n=5 lymph node invasion; n=1 metastatic disease. Median RAI dose administered on haemodialysis 100mCi. 7.5 years after radioiodine treatment on haemodialysis, n=7 deemed free of thyroid disease, n=1 persistent non-localised disease. No complications related to the procedure or other target organs were registered. After 3.25 years, n=4 patients underwent successful renal transplantation; n=4 patients did not meet transplantation criteria due to other conditions unrelated to the thyroid disease or its treatment. One patient died due to ischemic cardiomyopathy (free of thyroid disease). Radioiodine treatment during haemodialysis is a long-term, safe procedure without worsening prognosis of either renal or thyroid disease. Copyright © 2015 Elsevier España, S.L.U. and SEMNIM.

    Tumour cell–derived heat shock proteins (HSPs) are used as vaccines for immunotherapy of cancer patients. However, it is proposed that the peptide chaperoned on HSPs, not HSPs themselves, elicited a potent immune response. Given that HSPs are highly expressed by most myeloma cells and vital to myeloma cell survival, we reasoned that HSPs themselves might be an ideal myeloma antigen. In the present study, we explored the feasibility of targeting HSPs themselves for treating multiple myeloma. We identified and chose HLA-A*0201-binding peptides from human HSPB1 (HSP27) and HSP90AA1 (HSP90), and confirmed their immunogenicity in HLA-A*0201 transgenic mice. Dendritic cells pulsed with HSPB1 and HSP90AA1 peptides were used to stimulate peripheral blood mononuclear cells from healthy volunteers and myeloma patients to generate HSP peptide-specific cytotoxic T lymphocytes (CTLs). HSP peptide-specific CTLs efficiently lysed HLA-A*0201+ myeloma cells (established cell lines and primary plasma cells) but not HLA-A*0201− myeloma cells in vitro, indicating that myeloma cells naturally express HSP peptides in the context of major histocompatibility complex class I molecules. More importantly, HSP peptide-specific CTLs effectively reduced tumour burden in the xenograft mouse model of myeloma. Our study clearly demonstrated that HSPs might be novel tumour antigens for immunotherapy of myeloma. PMID:24824351

  14. Folliculin contributes to VHL tumor suppressing activity in renal cancer through regulation of autophagy.

    Directory of Open Access Journals (Sweden)

    Prabhat Bastola

    Full Text Available Von Hippel-Lindau tumor suppressor (VHL is lost in the majority of clear cell renal cell carcinomas (ccRCC. Folliculin (FLCN is a tumor suppressor whose function is lost in Birt-Hogg-Dubé syndrome (BHD, a disorder characterized by renal cancer of multiple histological types including clear cell carcinoma, cutaneous fibrofolliculoma, and pneumothorax. Here we explored whether there is connection between VHL and FLCN in clear cell renal carcinoma cell lines and tumors. We demonstrate that VHL regulates expression of FLCN at the mRNA and protein levels in RCC cell lines, and that FLCN protein expression is decreased in human ccRCC tumors with VHL loss, as compared with matched normal kidney tissue. Knockdown of FLCN results in increased formation of tumors by RCC cells with wild-type VHL in orthotopic xenografts in nude mice, an indication that FLCN plays a role in the tumor-suppressing activity of VHL. Interestingly, FLCN, similarly to VHL, is necessary for the activity of LC3C-mediated autophagic program that we have previously characterized as contributing to the tumor suppressing activity of VHL. The results show the existence of functional crosstalk between two major tumor suppressors in renal cancer, VHL and FLCN, converging on regulation of autophagy.

    The aim of this study was to assess the impact of sunitinib treatment in a non-screened group of patients with metastatic renal cell cancer (mRCC) treated by the Brazilian Unified Health System (SUS) at a single reference institution. Retrospective cohort study, which evaluated patients with mRCC who received sunitinib between May 2010 and December 2013. Fifty-eight patients were eligible. Most patients were male 41 (71%), with a median age of 58 years. Nephrectomy was performed in 41 (71%) patients with a median interval of 16 months between the surgery and initiation of sunitinib. The most prevalent histological subtype was clear cell carcinoma, present in 52 (91.2%) patients. In 50 patients (86%), sunitinib was the first line of systemic treatment. The main adverse effects were fatigue (57%), hypothyroidism (43%), mucositis (33%) and diarrhea (29%). Grade 3 and 4 adverse effects were infrequent: fatigue (12%), hypertension (12%), thrombocytopenia (7%), neutropenia (5%) and hand-foot syndrome (5%). Forty percent of patients achieved a partial response and 35% stable disease, with a disease control rate of 75%. Median progression free survival was 7.6 months and median overall survival was 14.1 months. Sunitinib treatment was active in the majority of patients, especially those with low and intermediate risk by MSKCC score, with manageable toxicity. Survival rates were inferior in this non-screened population with mRCC treated in the SUS. Copyright© by the International Brazilian Journal of Urology.

    Vascular endothelial growth factor receptor inhibitors, mammalian target of rapamycin inhibitors, and tyrosine kinase inhibitors are approved for metastatic renal cell cancer. Proteinuria can occur, but there is limited data regarding the incidence, monitoring, and management in metastatic renal cell cancer patients. Our primary objective was to describe the incidence and severity of proteinuria in metastatic renal cell cancer patients treated in the first-line setting with pazopanib, bevacizumab, or everolimus. We conducted a retrospective review of patients with metastatic renal cell cancer enrolled from January 2011-April 2013 in a phase II trial. Baseline and toxicity data were extracted from the electronic medical record. Descriptive statistics were used. In all, 129 patients were eligible for analysis. The overall incidence of proteinuria was 81%, with most events being Grade 1 or 2. The incidence of proteinuria was 80% (n = 35) for pazopanib, 64% (n = 25) for bevacizumab, and 96% (n = 44) for everolimus. At peak proteinuria, 80% (n = 28), 64% (n = 16), and 80% (n = 35) of patients on pazopanib, bevacizumab, and everolimus, respectively, were managed with continued monitoring at the same dose. The overall incidence of Grades 3 and 4 events was 24% (n = 6) and found in the bevacizumab group. A high incidence of proteinuria with minor severity within each class was demonstrated. It may be reasonable to continue therapy at the same dose for Grade 1 or 2 proteinuria. Treatment modification or discontinuation of therapy may be warranted with Grade 3 or 4 proteinuria. © The Author(s) 2014.

    Full Text Available Introduction. The clinical course of renal cancer remains difficult to predict. Attempts to appoint new independent prognostic factors (IPFs and comparisons of already identified ones among populations are inevitable to develop more effective prognostic instruments. The aim of this study was to evaluate IPFs of overall survival in a given population of patients with renal cancer.Materials and methods. Retrospective analysis of 148 patients with renal cancer treated at the Oncological Institute in Cracow from 2000 to 2007 was performed. Mean follow–up was 51 months. Using the log–rang test, a group of clinicopathological and biochemical features was analyzed in respect to their influence on overall survival. Results were presented as Kaplan–Meier curves. Final identification of IPFs was made by multivariate Cox regression analysis.Results. Overall survival rate at 1, 2, and 5–year follow–up was 58.8%, 38.2%, and 21.4%, respectively. The set of identified IPFs consisted of performance status, smoking history, hemoglobin concentration, anatomical staging, tumor grade, and the presence of microvascular invasion. It was confirmed that only nephrectomy increases significantly overall survival.Conclusions. Apart from smoking history, the role of all other IPFs identified in our study is well documented in the literature. Smoking history seems to be a new IPF with strong negative impact on survival in patients with RCC.

    Intraoperative radiotherapy (IORT) refers to the delivery of a single radiation dose to a limited volume of tissue during a surgical procedure. A literature review was performed to analyze the role of IORT in gynaecological and genito-urinary cancer including endometrial, cervical, renal, bladder and prostate cancers.Literature search was performed by Pubmed and Scopus, using the words "intraoperative radiotherapy/IORT", "gynaecological cancer", "uterine/endometrial cancer", "cervical/cervix cancer", "renal/kidney cancer", "bladder cancer" and "prostate cancer". Forty-seven articles were selected from the search databases, analyzed and briefly described.Literature data show that IORT has been used to optimize local control rate in genito-urinary tumours mainly in retrospective studies. The results suggest that IORT could be advantageous in the setting of locally advanced and recurrent disease although further prospective trials are needed to confirm this findings.

    The renal cell carcinomas (RCC), clear cell, papillary, and chromophobe, have recently undergone an unmatched genomic characterization by The Cancer Genome Atlas. This analysis has revealed new insights into each of these malignancies and underscores the unique biology of clear cell, papillary, and chromophobe RCC. Themes that have emerged include distinct mechanisms of metabolic dysregulation and common mutations in chromatin modifier genes. Importantly, the papillary RCC classification encompasses a heterogeneous group of diseases, each with highly distinct genetic and molecular features. In conclusion, this review summarizes RCCs that represent a diverse set of malignancies, each with novel biologic programs that define new paradigms for cancer biology.

    Full Text Available Role of free radicals has been proposed in the pathogenesis of many diseases. Gastric cancer is a common disease worldwide, and leading cause of cancer death in India. Severe oxidative stress produces reactive oxygen species (ROS and induces uncontrolled lipid peroxidation. Albumin, uric acid (UA and Bilirubin are important physiological antioxidants. We aimed to evaluate and assess the role of oxidative stress (OS and physiological antioxidant system in stomach cancer patients. Lipid peroxidation measured as plasma Thio Barbituric Acid Reactive substances (TBARS, was found to be elevated significantly (p=0.001 in stomach cancer compared to controls along with a decrease in plasma physiological antioxidant system. The documented results were due to increased lipid peroxidation and involvement of physiological antioxidants in scavenging free radicals but not because of impaired hepatic and renal functions.

    The treatment of multiple myeloma has changed dramatically in the past decade. The increase in the number of active agents has generated numerous possible drug combinations that can be used in the first-line and relapsed settings. As a result, there is considerable confusion about the choice of regimens for initial therapy, role of transplantation in the era of new drugs, end points for therapy, and the role of maintenance therapy. A hotly debated area is whether treatment approaches should achieve cure or disease control, which impacts greatly on the treatment strategy employed. This article provides an update on the treatment of multiple myeloma, with a focus on recent advances, newly diagnosed disease, role of transplantation and maintenance therapy. A synthesized approach to the treatment of myeloma is presented, along with a discussion of key paradigms that need to be challenged.

    Full Text Available We conducted a case-control study of renal cancer (987 cases and 1298 controls in Central and Eastern Europe and analyzed genomic DNA for 319 tagging single-nucleotide polymorphisms (SNPs in 21 genes involved in cellular growth, differentiation and apoptosis using an Illumina Oligo Pool All (OPA. A haplotype-based method (sliding window analysis of consecutive SNPs was used to identify chromosome regions of interest that remained significant at a false discovery rate of 10%. Subsequently, risk estimates were generated for regions with a high level of signal and individual SNPs by unconditional logistic regression adjusting for age, gender and study center. Three regions containing genes associated with renal cancer were identified: caspase 1/5/4/12(CASP 1/5/4/12, epidermal growth factor receptor (EGFR, and insulin-like growth factor binding protein-3 (IGFBP3. We observed that individuals with CASP1/5/4/12 haplotype (spanning area upstream of CASP1 through exon 2 of CASP5 GGGCTCAGT were at higher risk of renal cancer compared to individuals with the most common haplotype (OR:1.40, 95% CI:1.10-1.78, p-value = 0.007. Analysis of EGFR revealed three strong signals within intron 1, particularly a region centered around rs759158 with a global p = 0.006 (GGG: OR:1.26, 95% CI:1.04-1.53 and ATG: OR:1.55, 95% CI:1.14-2.11. A region in IGFBP3 was also associated with increased risk (global p = 0.04. In addition, the number of statistically significant (p-value<0.05 SNP associations observed within these three genes was higher than would be expected by chance on a gene level. To our knowledge, this is the first study to evaluate these genes in relation to renal cancer and there is need to replicate and extend our findings. The specific regions associated with risk may have particular relevance for gene function and/or carcinogenesis. In conclusion, our evaluation has identified common genetic variants in CASP1, CASP5, EGFR, and IGFBP3 that could be

    Recombinant human erythropoietin (rHuEpo) was introduced into clinical practice more than a decade ago, and has been found to be effective in the treatment of several types of anemia, including anemia of end-stage renal failure and cancer-related anemia. No study has suggested that Epo might have an effect on the biology of the disease, nor any survival advantage to cancer patients treated with Epo for anemia has been reported. Here we report six patients with advanced multiple myeloma (MM) with very poor prognostic features, whose expected survival was cells. We then presented evidence that the mechanism is a new immune-mediated phenomenon, via activation of CD8+ T cells. Furthermore, evidence from the literature supports the antineoplastic effect of Epo. Epo might be used as an adjunct immune treatment in various malignant diseases, in addition to the current regimens and chemotherapeutic protocols. Future trials should determine the role of Epo in myeloma and cancer treatment, besides clarifying concerns about the presence of Epo receptors on some tumor cells.

  13. Should a Study of Monoclonal Gammopathy of Undetermined Significance Be of Clinical Interest to Predict Myeloma Overcome?

    Directory of Open Access Journals (Sweden)

    J Véronique-Baudin

    2016-02-01

    Full Text Available The majority of monoclonal gammopathy of undetermined significance (MGUS are benign forms that require no treatment but can be considered as a pre-cancerous state. Monoclonal gammopathy of undetermined significance is quite frequent, and related to age. The risk of progression to multiple myeloma or another type of malignant lymphoproliferation is estimated at 1% per year. Monoclonal gammopathy of undetermined significance is twice as frequent in patients of African descent, and prevalence is higher for men. Diagnosis of MGUS is made on evidence of a monoclonal component < 30 g/L and no CRAB criteria (hypercalcaemia, renal insufficiency, anaemia, bone lesions. Regular monitoring is required for all MGUS because they can develop into other lymphoproliferative disorders such as multiple myeloma and lymphoma and other haematologic malignancies. In view of the genetic, insular and environmental context specificities of Caribbean populations of African descent, and according to haemophilia trends of the French West Indies cancer registry, it will be interesting to determine incidence and prevalence of MGUS in a country in the Caribbean. No such study has been performed to date. There is a hypothesis for a possible geographic distribution of these blood disorders linked to environmental exposure to pesticides. The expected findings and their potential repercussions will have major public health interest, and should form the basis for a wider prognostic study to determine risk factors for MGUS in the French Caribbean. In a real life exhaustive study, the Martinique Cancer Registry proposes an epidemiological focus on MGUS in Martinique.

    The utility of cancer cell lines is affected by the similarity to endogenous tumour cells. Here we compare genomic data from 65 kidney-derived cell lines from the Cancer Cell Line Encyclopedia and the COSMIC Cell Lines Project to three renal cancer subtypes from The Cancer Genome Atlas: clear cell renal cell carcinoma (ccRCC, also known as kidney renal clear cell carcinoma), papillary (pRCC, also known as kidney papillary) and chromophobe (chRCC, also known as kidney chromophobe) renal cell carcinoma. Clustering copy number alterations shows that most cell lines resemble ccRCC, a few (including some often used as models of ccRCC) resemble pRCC, and none resemble chRCC. Human ccRCC tumours clustering with cell lines display clinical and genomic features of more aggressive disease, suggesting that cell lines best represent aggressive tumours. We stratify mutations and copy number alterations for important kidney cancer genes by the consistency between databases, and classify cell lines into established gene expression-based indolent and aggressive subtypes. Our results could aid investigators in analysing appropriate renal cancer cell lines.

    Full Text Available Abstract Background Secondary radiation-induced cancers are rare but well-documented as long-term side effects of radiation in large populations of breast cancer survivors. Multiple neoplasms are rare. We report a case of esophageal adenocarcinoma in a patient treated previously for breast cancer and clear cell carcinoma of the kidney. Case presentation A 56 year-old non smoking woman, with no alcohol intake and no familial history of cancer; followed in the National Institute of Oncology of Rabat Morocco since 1999 for breast carcinoma, presented on consultation on January 2011 with dysphagia. Breast cancer was treated with modified radical mastectomy, 6 courses of chemotherapy based on CMF regimen and radiotherapy to breast, inner mammary chain and to pelvis as castration. Less than a year later, a renal right mass was discovered incidentally. Enlarged nephrectomy realized and showed renal cell carcinoma. A local and metastatic breast cancer recurrence occurred in 2007. Patient had 2 lines of chemotherapy and 2 lines of hormonotherapy with Letrozole and Tamoxifen assuring a stable disease. On January 2011, the patient presented dysphagia. Oesogastric endoscopy showed middle esophagus stenosing mass. Biopsy revealed adenocarcinoma. No evidence of metastasis was noticed on computed tomography and breast disease was controlled. Palliative brachytherapy to esophagus was delivered. Patient presented dysphagia due to progressive disease 4 months later. Jejunostomy was proposed but the patient refused any treatment. She died on July 2011. Conclusion We present here a multiple neoplasm in a patient with no known family history of cancers. Esophageal carcinoma is most likely induced by radiation. However the presence of a third malignancy suggests the presence of genetic disorders.

    A 64-year-old woman received nephrectomy and lymph expurgation surgery for renal cell carcinoma on Jury 1, 1981. The pathologic diagnosis was adenocarcinoma of the clear cell type at Robson's stage 2. She next visited the Department of Gastroenterology complaining of stomach discomfort on November 5, 1981. Stomach cancer of Borrmann's type IV was identified in the lesser gastric curvature, but only biopsy was performed because it was inoperable. The pathologic diagnosis was undifferentiated adenocarcinoma. On January 23, 1982, there was microscopic hematuria. A cystoscopic examination revealed one soy bean-sized, smooth, pedicle tumor to which coagula were partially adhered in the center of the triangular region. After TUR-Bt performed on March 3 the pathologic diagnosis was adenocarcinoma of the clear cell type with no submucosal infiltration. Based on these findings, the patient was diagnosed as having suffered metastasis of renal cell carcinoma to the bladder. She died of bleeding from stomach cancer on June 15. Based on the fact that the tumor was localized in the bladder mucosa, implantation through the urinary tract was strongly suspected as the metastatic route of the renal cell carcinoma to the bladder.

    Efficient renal clearance is of fundamentally important property of nanoparticles for their in vivo biomedical applications. In this work, we report the successful synthesis of ultra-small Pd nanosheets (SPNS) with an average diameter of 4.4 nm and their application in photothermal cancer therapy using a near infrared laser. The ultra-small Pd nanosheets have strong optical absorption in the NIR region and high photothermal conversion efficiency (52.0%) at 808 nm. After being surface-functionalized with reduced glutathione (GSH), the SPNS-GSH was administered to mice to investigate the biodistribution, photothermal efficacy and tumor ablation in vivo. The in vivo photothermal therapy studies clearly demonstrate that surface modification with GSH allows the nanosheets to exhibit prolonged blood circulation and thus high accumulation in tumors. Upon 808 nm NIR irradiation, the tumors can be completely ablated. More importantly, with the size below the renal filtration limit (photothermal therapy, the unique renal clearance properties make the ultra-small Pd nanosheets promising for practical use in photothermal cancer therapy.

    2013-10-01

    The transcription factor E2F1 has both oncogenic and tumour suppressor properties, depending on the context. Clarifying the function of E2F1 in different types of cancer is relevant because in those situations in which it acts as an oncogene there may be a route for therapeutic interference. Renal cell carcinoma is the most frequent form of kidney cancer in adults and inactivation of the von Hippel-Lindau (VHL) gene underlies most cases. This malignancy represents a challenge for standard therapies due to drug- and radio-resistance, effects that fit well within the scope of functions of E2F1. A new report by Mans et al postulates that up-regulation of E2F1 in VHL-defective renal cell carcinoma induces cell senescence and can thus be considered a good prognostic factor. Here we discuss these findings in a wider context and propose that E2F1 may actually not play a uniform role in renal cell carcinoma but rather an ambiguous one whose deeper understanding could have practical implications.

    We investigated malignancy risk after renal transplantation in patients with and without systemic lupus erythematosus (SLE). Using the United States Renal Data System from 2001 to 2009, 143 652 renal transplant recipients with and without SLE contributed 585 420 patient-years of follow-up to determine incident cancers using Medicare claims codes. We calculated standardised incidence ratios (SIRs) of cancer by group using age, sex, race/ethnicity-specific and calendar year-specific cancer rates compared with the US population. 10 160 cancers occurred at least 3 months after renal transplant. Overall cancer risk was increased in both SLE and non-SLE groups compared with the US general population, SIR 3.5 (95% CI 2.1 to 5.7) and SIR 3.7 (95% CI 2.4 to 5.7), respectively. Lip/oropharyngeal, Kaposi, neuroendocrine, thyroid, renal, cervical, lymphoma, liver, colorectal and breast cancers were increased in both groups, whereas only melanoma was increased in SLE and lung cancer was increased in non-SLE. In Cox regression analysis, SLE status (HR 1.1, 95% CI 0.9 to 1.3) was not associated with increased risk of developing cancer, adjusted for other independent risk factors for developing cancer in renal transplant recipients. We found that smoking (HR 2.2, 95% CI 1.2 to 4.0), cytomegalovirus positivity at time of transplant (HR 1.3, 95% CI 1.2 to 1.4), white race (HR 1.2, 95% CI 1.2 to 1.3) and older recipient age at time of transplantation (HR 1.0 95% CI 1.0 to 1.2) were associated with an increased risk for development of cancer, whereas shorter time on dialysis, Epstein-Barr virus or HIV were associated with a lower risk for development of cancer. Cancer risk in renal transplant recipients appeared similar in SLE and non-SLE subjects, aside from melanoma. Renal transplant recipients may need targeted counselling regarding surveillance and modifiable risk factors.

  1. Inhibition of fatty acid metabolism reduces human myeloma cells proliferation.

    José Manuel Tirado-Vélez

    Full Text Available Multiple myeloma is a haematological malignancy characterized by the clonal proliferation of plasma cells. It has been proposed that targeting cancer cell metabolism would provide a new selective anticancer therapeutic strategy. In this work, we tested the hypothesis that inhibition of β-oxidation and de novo fatty acid synthesis would reduce cell proliferation in human myeloma cells. We evaluated the effect of etomoxir and orlistat on fatty acid metabolism, glucose metabolism, cell cycle distribution, proliferation, cell death and expression of G1/S phase regulatory proteins in myeloma cells. Etomoxir and orlistat inhibited β-oxidation and de novo fatty acid synthesis respectively in myeloma cells, without altering significantly glucose metabolism. These effects were associated with reduced cell viability and cell cycle arrest in G0/G1. Specifically, etomoxir and orlistat reduced by 40-70% myeloma cells proliferation. The combination of etomoxir and orlistat resulted in an additive inhibitory effect on cell proliferation. Orlistat induced apoptosis and sensitized RPMI-8226 cells to apoptosis induction by bortezomib, whereas apoptosis was not altered by etomoxir. Finally, the inhibitory effect of both drugs on cell proliferation was associated with reduced p21 protein levels and phosphorylation levels of retinoblastoma protein. In conclusion, inhibition of fatty acid metabolism represents a potential therapeutic approach to treat human multiple myeloma.

    Full Text Available Raphael E Steiner, Elisabet E Manasanch Department of Lymphoma and Myeloma, The University of Texas MD Anderson Cancer Center, Houston, TX, USA Abstract: Carfilzomib is a proteasome inhibitor that binds selectively and irreversibly to the 20S proteasome, the proteolytic core particle within the 26S proteasome, resulting in the accumulation of proteasome substrates and ultimately growth arrest and apoptosis of tumor cells. The development and ultimate approval of this medication by regulatory agencies has been an important step toward improving clinical outcomes in multiple myeloma. Although initially approved as a single agent for the treatment of multiply relapsed and/or refractory myeloma, in the USA, it is now widely used in the early relapse setting in combination with lenalidomide and dexamethasone. Carfilzomib has also been studied in combination with second-generation immunomodulatory drugs, histone deacetylase inhibitors, alkylating agents and other novel medications. In this review article, we will discuss the efficacy, safety, tolerability and quality of life of carfilzomib-based combination therapies, as well as novel agents, for relapsed multiple myeloma.

    Folliculin-interacting protein 1 and 2 (FNIP1 and FNIP2) play critical roles in preventing renal malignancy through their association with the tumor suppressor FLCN. Mutations in FLCN are associated with Birt-Hogg-Dubé (BHD) syndrome, a rare disorder with increased risk of renal cancer. Recent studies indicated that FNIP1/FNIP2 double knockout mice display enlarged polycystic kidneys and renal carcinoma, which phenocopies FLCN knockout mice, suggesting that these two proteins function together to suppress renal cancer. However, the molecular mechanism functionally linking FNIP1/FNIP2 and FLCN remains largely elusive. Here, we demonstrated that FNIP2 protein is unstable and subjected to proteasome-dependent degradation via β-TRCP and Casein Kinase 1 (CK1)-directed ubiquitination in a nutrition-dependent manner. Degradation of FNIP2 leads to lysosomal dissociation of FLCN and subsequent lysosomal association of mTOR, which in turn promotes the proliferation of renal cancer cells. These results indicate that SCFβ-TRCP negatively regulates the FLCN complex by promoting FNIP degradation and provide molecular insight into the pathogenesis of BHD-associated renal cancer.

    Full Text Available INTRODUCTION: Folate and one-carbon metabolism are linked to cancer risk through their integral role in DNA synthesis and methylation. Variation in one-carbon metabolism genes, particularly MTHFR, has been associated with risk of a number of cancers in epidemiologic studies, but little is known regarding renal cancer. METHODS: Tag single nucleotide polymorphisms (SNPs selected to produce high genomic coverage of 13 gene regions of one-carbon metabolism (ALDH1L1, BHMT, CBS, FOLR1, MTHFR, MTR, MTRR, SHMT1, SLC19A1, TYMS and the closely associated glutathione synthesis pathway (CTH, GGH, GSS were genotyped for 777 renal cell carcinoma (RCC cases and 1,035 controls in the Central and Eastern European Renal Cancer case-control study. Associations of individual SNPs (n = 163 with RCC risk were calculated using unconditional logistic regression adjusted for age, sex and study center. Minimum p-value permutation (Min-P tests were used to identify gene regions associated with risk, and haplotypes were evaluated within these genes. RESULTS: The strongest associations with RCC risk were observed for SLC19A1 (P(min-P = 0.03 and MTHFR (P(min-P = 0.13. A haplotype consisting of four SNPs in SLC19A1 (rs12483553, rs2838950, rs2838951, and rs17004785 was associated with a 37% increased risk (p = 0.02, and exploratory stratified analysis suggested the association was only significant among those in the lowest tertile of vegetable intake. CONCLUSIONS: To our knowledge, this is the first study to comprehensively examine variation in one-carbon metabolism genes in relation to RCC risk. We identified a novel association with SLC19A1, which is important for transport of folate into cells. Replication in other populations is required to confirm these findings.

    OBJECTIVE To investigate the clinical characteristics and laboratory findings of patients with light-chain multiple myeloma. METHODS Fourty-three patients with light chain myeloma over a 13year period were analyzed retrospectively and 43 cases with IgG type myeloma in the same period were used as control. RESULTS Of the 43 patients, 28 were male, 15 were female, with an overall mean age of 57 years (range, 36-71). At the time of onset, the main symptoms were fatigue and dizziness (23 cases, 53.5%) and bone pain (25, 58.1%). The main signs were anemia (28, 65.1%) and bone pressure pain (23, 53.5%). Of 39 patients with determined staging, 38 were in stage Ⅲ and 1 stage Ⅰ. Renal function examinations were performed for 31 patients. Among them, 16 were in stage ⅢB and 15 in ⅡA. Hypercalcemia (≥3 mmol/L) occurred in 2 cases. Of 18 patients, 3 had proteinuria ≥12 g per 24 hours. Osteolytic lesions appeared in 27 of 31 cases. No abnormal globulin peaks were found in the serum protein electrophoretic bands. Serum and urine immunoelectrophoresis showed that 10 cases were kappa light chain, 29 were lambda light chain and 4 were both. Nineteen patients received chemotherapy, of which 8 cases obtained complete remission and 11 had no remission. CONCLUSION Because of poor differentiation, skeletal destruction and renal dysfunction, light chain multiple myeloma patients have meager therapeutical efficacy and poor prognosis.

    2012-02-15

    MicroRNAs are short noncoding RNAS involved in gene expression regulation under physiological and pathological situations. They bind to mRNA of target genes and are potential regulators of gene expression at a post-transcription level through the RNA interference pathway. They are estimated to represent 1% to 2% of the known eukaryotic genome, and it has been demonstrated that they are involved in the pathogenesis of neurodegenerative diseases, cancer, metabolism disorders, and heart disease. MicroRNAs are known to act as tumor suppressors or oncogenes in cancer biology. The authors describe the current knowledge on microRNA involvement in regulatory pathways that characterize multiple myeloma pathogenesis gained from in vitro and in vivo studies. These small molecules interact with important factors such as p53, SOCS1, IGF-1, IGF-1R, vascular endothelial growth factor, NF-κB, and others. As such, microRNAs represent an attractive therapeutic target in the context of multiple myeloma interfering with the myeloma regulatory networks. Further studies are needed to better understand their role in myelomagenesis and their therapeutic potential.

    Renal cell carcinoma (RCC) is the most frequent upper urinary tract cancer in humans and accounts for 80-85% of malignant renal tumors. Eker rat represents a unique animal model to study RCC since these rats develop spontaneous renal tumors and leiomyoma, which may be due to tuberous sclerosis 2 (TSC2) mutation resulting in the activation of the mammalian target of rapamycin (mTOR) pathway. This study examines the role of a lycopene-rich diet in the development of RCC in the TSC2 mutant Eker rat model. Ten-week old female Eker rats (n=90) were assigned in equal numbers to receive 0, 100 or 200mg/kg of lycopene as part of their daily diet. After 18 months the rats were sacrificed and the kidneys were removed. Immunohistochemical staining with antibodies against mTOR, phospho-S6 and EGFR were performed, as well as hematoxylin-eosin staining for histologic examination of the tumors. Tumors were counted and measured in individual kidneys. Presence of tumor decreased from 94% in control animals to 65% in the experimental group, but the difference was not statistically significant (Plycopene-treated rats (Plycopene group, tumor numbers decreased (Plycopene increased from 0 to 200. Control rats fed only basal diet had a greater length of tumors (23.98 mm) than rats fed lycopene supplement groups (12.90 mm and 11.07 mm) (Plycopene increased from 0 to 200mg/kg. All tumors showed strong staining with antibodies against mTOR, phospho-S6 and EGFR. In conclusion, dietary supplementation with lycopene attenuates the development of renal cell cancers in the predisposed TSC2 mutant Eker rat model. These results suggest that lycopene may play a role in the prevention of RCC.

    Isoenzymes of HEX from human renal carcinoma and neighbouring macroscopically normal renal tissue can show different patterns on isoelectrofocusing gels. The aim of our work was to elaborate the method for statistical evaluation of differences. Isoenzymes of N-acetyl-beta-hexosaminidase were separated from renal (control and cancerous) tissues of 15 patients. Isoenzymes were electrofocused in Multiphor II, with ampholine pH 3.5-9.0 (2%) and then evaluated densitometrically and analysed statistically. A similar pattern in activity of isoforms of isoenzymes A and B in normal and cancerous renal tissue was observed. The proposed method of statistical evaluation of differences in isoforms of N-acetyl-beta-glucosaminidase can also be adapted to estimate the isoforms of other enzymes in different tissues.

    Abnormal localization of tumor suppressor proteins is a common feature of renal cancer. Nuclear export of these tumor suppressor proteins is mediated by chromosome region maintenance-1 (CRM1). Here, we investigated the antitumor eff ects of a novel reversible inhibitor of CRM1 on renal cancer cells. We found that S109 inhibits the CRM1-mediated nuclear export of RanBP1 and reduces protein levels of CRM1. Furthermore, the inhibitory eff ect of S109 on CRM1 is reversible. Our data demonstrated that S109 signifi cantly inhibits proliferation and colony formation of renal cancer cells. Cell cycle assay showed that S109 induced G1-phase arrest, followed by the reduction of Cyclin D1 and increased expression of p53 and p21. We also found that S109 induces nuclear accumulation of tumor suppressor proteins, Foxo1 and p27. Most importantly, mutation of CRM1 at Cys528 position abolished the eff ects of S109. Taken together, our results indicate that CRM1 is a therapeutic target in renal cancer and the novel reversible CRM1 inhibitor S109 can act as a promising candidate for renal cancer therapy.

    To compare N-acetyl-beta-hexosaminidase (HEX) activity in the serum and urine of smokers as well as non-smokers with renal cancer, and healthy people. To assess hexosaminidase activity the level of p-nitrophenol released from p-nitrophenol derivatives was measured. The activity of enzyme was significantly higher in cancer group, with the highest activity in non-smokers. Cigarette smoking can inhibit, by the influence on HEX activity, catabolism of oligosaccharide chains in cancer tissues.

    Renal cell cancer (RCC) represents 2-3% of all cancers and is the most lethal of the urologic malignancies, in a minority of cases caused by a genetic predisposition. Birt-Hogg-Dubé syndrome (BHD) is one of the hereditary renal cancer syndromes. As the histological subtype and clinical presentation in BHD are highly variable, this syndrome is easily missed. Lung cysts--mainly under the main carina--are reported to be present in over 90% of all BHD patients and might be an important clue in differentiating between sporadic RCC and BHD associated RCC. We conducted a retrospective study among patients diagnosed with sporadic RCC, wherein we retrospectively scored for the presence of lung cysts on thoracic CT. We performed FLCN mutation analysis in 8 RCC patients with at least one lung cysts under the carina. No mutations were identified. We compared the radiological findings in the FLCN negative patients to those in 4 known BHD patients and found multiple basal lung cysts were present significantly more frequent in FLCN mutation carriers and may be an indication for BHD syndrome in apparent sporadic RCC patients.

    In recent years, an increasing number of TFE3 rearrangement-associated tumors with melanotic features have been reported as primary neoplasm in different anatomical sites, including the kidney. Melanotic Xp11 translocation renal cancer (MXTRC) and Xp11 renal cell carcinoma with melanotic features (XRCCM) have been proposed to be main categories for pigmented lesions in the microophthalmia-associated transcription factor (MiTF/TFE3) family of renal tumors that may show variable degrees of melanocytic differentiation. Herein we report a rare case of TFE3-related pigmented renal tumor showing unusual immunoexpression of cytokeratins (AE1/AE3) and renal cell carcinoma markers (RCC, CD10). Cathepsin-K and Vimentin were diffusely positive whereas melanocytic markers (HMB-45 and Melan-A) displayed weak and patchy expression. We found no labelling for PAX-8, muscle markers (desmin, smooth muscle actin, muscle-specific actin and caldesmon) and S-100. TFE3 fusion was confirmed by break-apart fluorescence in situ hybridization (FISH). This case corroborates previous evidence for overlap in the TFE3-associated cancer family and illustrates that it may not be possible to set a clear cutoff between epithelial (XRCCM) and mesenchymal (MXTRC) subgroups.

    Multiple myeloma remains treatable but incurable. Despite a growing armamentarium of effective agents, choice of therapy, especially in relapse, still relies almost exclusively on clinical acumen. We have developed a system, Ex vivo Mathematical Myeloma Advisor (EMMA), consisting of patient-specific mathematical models parameterized by an ex vivo assay that reverse engineers the intensity and heterogeneity of chemosensitivity of primary cells from multiple myeloma patients, allowing us to predict clinical response to up to 31 drugs within 5 days after bone marrow biopsy. From a cohort of 52 multiple myeloma patients, EMMA correctly classified 96% as responders/nonresponders and correctly classified 79% according to International Myeloma Working Group stratification of level of response. We also observed a significant correlation between predicted and actual tumor burden measurements (Pearson r = 0.5658, P multiple myeloma patient samples, yielded consistent results with recent phase I/II trials, suggesting that EMMA is a feasible platform for estimating clinical efficacy of drugs and inclusion criteria screening. This unique platform, specifically designed to predict therapeutic response in multiple myeloma patients within a clinically actionable time frame, has shown high predictive accuracy in patients treated with combinations of different classes of drugs. The accuracy, reproducibility, short turnaround time, and high-throughput potential of this platform demonstrate EMMA's promise as a decision support system for therapeutic management of multiple myeloma.

    In the era of new and mostly effective therapeutic protocols, multiple myeloma still tends to be a hard-to-treat hematologic cancer. This hallmark of the disease is in fact a sequel to drug resistant phenotypes persisting initially or emerging in the course of treatment. Furthermore, the heterogeneous nature of multiple myeloma makes treating patients with the same drug challenging because finding a drugable oncogenic process common to all patients is not yet feasible, while our current knowledge of genetic/epigenetic basis of multiple myeloma pathogenesis is outstanding. Nonetheless, bone marrow microenvironment components are well known as playing critical roles in myeloma tumor cell survival and environment-mediated drug resistance happening most possibly in all myeloma patients. Generally speaking, however; real mechanisms underlying drug resistance in multiple myeloma are not completely understood. The present review will discuss the latest findings and concepts in this regard. It reviews the association of important chromosomal translocations, oncogenes (e.g. TP53) mutations and deranged signaling pathways (e.g. NFκB) with drug response in clinical and experimental investigations. It will also highlight how bone marrow microenvironment signals (Wnt, Notch) and myeloma cancer stem cells could contribute to drug resistance in multiple myeloma. PMID:24327604

    Renal cancer is rare and its incidence is 1.9 per 100,000 in the Malaysian population, which consists of three major ethnic groups (Malay, Chinese and Indians). A retrospective study was her conducted to identify clinical characteristics and ethnic background influences on presentation. The study included all renal cancer patients from a single medical institution over ten years, with a total of 75 cases. Seventy-three patients underwent surgery while 2 received only radiotherapy or chemotherapy. The male to female ratio was 2.75:1. Incidence was equal among the Malay (49.3%) and Chinese ethnic groups (45.3%). Mean age of patients were 57.1 (18-93) years old. There were 26 (37.4%) patients with Stage I disease, 14 (18.7%) at Stage II, 23 (30.7%) at Stage III and 12 (16%) at Stage IV. The Chinese race presented at mean older age (p= 0.02) and later stage of disease (p= 0.046). Patients above 40 years old had more advanced stage disease (p= 0.023). Tumour histology were clear cell (72%), urothelial cell (13.3%), sarcomatoid cell and nephroblastoma each contributed 2.7%. The mean tumour size was 8.1 (2-20) cm. There was substantial agreement between the pre and post operative staging (kappa 0.691). In conclusion we observed significant influences of age and race in the clinical presentation of renal cancer in our institution based population. There was larger male to female ratio and mean tumour size as compared to previous epidemiology studies.

    Multiple myeloma (MM) is a clonal plasma cell malignancy clinically characterized by osteolytic lesions, immunodeficiency, and renal disease. There are an estimated 750,000 people diagnosed with MM worldwide, with a median overall survival of 3 - 5 years. Besides chromosomal aberrations, translocations, and mutations in essential growth and tumor-suppressor genes, accumulating data strongly highlight the pathophysiologic role of the bone marrow (BM) microenvironment in MM pathogenesis. Based on this knowledge, several novel agents have been identified, and treatment options in MM have fundamentally changed during the last decade. Thalidomide, bortezomib, and lenalidomide have been incorporated into conventional cytotoxic and transplantation regimens, first in relapsed and refractory and now also in newly diagnosed MM. Despite these significant advances, there remains an urgent need for more efficacious and tolerable drugs. Indeed, a plethora of preclinical agents awaits translation from the bench to the bedside. This article reviews the scientific rationale of new therapy regimens and newly identified therapeutic agents - small molecules as well as therapeutic antibodies - that hold promise to further improve outcome in MM.

    To assess the utility of single section cine MR images in evaluation of extrarenal invasion of renal cell cancer. Six patients who subsequently underwent definitive surgery were examined. Sequential twenty FLASH images were acquired in coronal and parasagittal single section during one respiratory cycle. These images were evaluated in cine-loop mode to assess tumoral movement with adjacent structures. Cine MR images showed that the tumor in one patient were fixed to the spleen and the tumors in five patients showed free movement. At pathologic examination, cine MR findings were proved correct in all patients. Cine MR images may be useful for pre-operative evaluation of extrarenal invasion. (author).

    Full Text Available Renal cell carcinoma (RCC is one of the most common kidney malignancies. An upgraded comprehension of the molecular biology implicated in the development of cancer has stimulated an increase in research and development of innovative antitumor therapies. The aim of the study was to analyze the medical literature for hypertension and renal toxicities as the adverse events of the vascular endothelial growth factor (VEGF signaling pathway inhibitor (anti-VEGF therapy. Relevant studies were identified in PubMed and ClinicalTrials.gov databases. Eligible studies were phase III and IV prospective clinical trials, meta-analyses and retrospective studies that had described events of hypertension or nephrotoxicity for patients who received anti-VEGF therapy. A total of 48 studies were included in the systematic review. The incidence of any grade hypertension ranged from 17% to 49.6%. Proteinuria and increased creatinine levels were ascertained in 8% to 73% and 5% to 65.6% of patients, respectively. These adverse events are most often mild in severity but may sometimes lead to treatment discontinuation. Nephrotoxicity and hypertension are related to multiple mechanisms; however, one of the main disturbances in those patients is VEGF inhibition. There is a significant risk of developing hypertension and renal dysfunction among patients receiving anti-VEGF treatment; however, there is also some evidence that these side effects may be used as biomarkers of response to antiangiogenic agents.

    Full Text Available Bevacizumab, a monoclonal antibody against vascular endothelial growth factor (VEGF, is employed for treatment of several cancers and retinopathies. Although previous reports of remission of psoriasis with bevacizumab do exist, but its current experience for psoriatic arthritis (PsA is still limited. In this report, we describe a patient with metastatic renal cell cancer, psoriasis and PsA, who experienced a complete remission of psoriasis and PsA during bevacizumab therapy without any other management for psoriasis and PsA. We also found a flare up of his psoriatic disease after switching to other kinase inhibitors like sorafenib or sunitinib. This suggests that bevacizumab might have a promising future in the treatment of psoriasis and PsA.

    Full Text Available Among 792 patients with multiple myeloma treated from 1987 to 2010 and assessed after 18 months, there were 167 patients with complete remission. For those 60 patients treated between 1987–1998 and with long followup, the latest relapse occurred after 11.8 years, so that 13 patients have remained in sustained complete remission for longer than 12 years (range 12–22 years. These results suggest that 3% of all patients treated during that period may be cured of multiple myeloma. In addition to immunofixation, more sensitive techniques for the detection of residual disease should be applied more consistently in patients with apparent complete remission in order to identify those with potential cure.

    To determine whether patient-specific 3D printed renal tumor models change pre-operative planning decisions made by urological surgeons in preparation for complex renal mass surgical procedures. From our ongoing IRB approved study on renal neoplasms, ten renal mass cases were retrospectively selected based on Nephrometry Score greater than 5 (range 6-10). A 3D post-contrast fat-suppressed gradient-echo T1-weighted sequence was used to generate 3D printed models. The cases were evaluated by three experienced urologic oncology surgeons in a randomized fashion using (1) imaging data on PACS alone and (2) 3D printed model in addition to the imaging data. A questionnaire regarding surgical approach and planning was administered. The presumed pre-operative approaches with and without the model were compared. Any change between the presumed approaches and the actual surgical intervention was recorded. There was a change in planned approach with the 3D printed model for all ten cases with the largest impact seen regarding decisions on transperitoneal or retroperitoneal approach and clamping, with changes seen in 30%-50% of cases. Mean parenchymal volume loss for the operated kidney was 21.4%. Volume losses >20% were associated with increased ischemia times and surgeons tended to report a different approach with the use of the 3D model compared to that with imaging alone in these cases. The 3D printed models helped increase confidence regarding the chosen operative procedure in all cases. Pre-operative physical 3D models created from MRI data may influence surgical planning for complex kidney cancer.

  7. New prognostic biomarkers in multiple myeloma

    2016-01-01

    Full Text Available Multiple myeloma is a malignant neoplastic disease, characterized by uncontrolled proliferation and accumulation of plasma cells in the bone marrow, which is usually connected with production of a monoclonal protein. It is the second most common hematologic malignancy. It constitutes approximately 1% of all cancers and 10% of hematological malignancies. Despite the huge progress that has been made in the treatment of multiple myeloma in the past 30 years including the introduction of new immunomodulatory drugs and proteasome inhibitors, it is still an incurable disease. According to current data, the five-year survival rate is 45%. Multiple myeloma is a very heterogeneous disease with a very diverse clinical course, which is expressed by differences in effectiveness of therapeutic strategies and ability to develop chemoresistance. This diversity implies the need to define risk stratification factors that would help to create personalized and optimized therapy and thereby improve treatment outcomes. Prognostic markers that aim to objectively evaluate the risk of a poor outcome, relapse and the patient’s overall outcome are useful for this purpose. The existing, widely used prognostic classifications, such as the Salmon-Durie classification or ISS, do not allow for individualization of treatment. As a result of the development of diagnostic techniques, especially cytogenetics and molecular biology, we were able to discover a lot of new, more sensitive and specific prognostic factors. The paper presents recent reports on the role of molecular, cytogenetic and biochemical alterations in pathogenesis and prognosis of the disease.

    We evaluated 45 cases of multiple myelomas retrospectively confirmed in Severance Hospital from the period of 1983-1989. In order to assess the radiologic features of the multiple myeloma and to assist in possible early diagnosis and treatment. The result were as follows: 1. IgG(41%) was the most common immunoglobulin type secreted followed by light chain(36%). IgA(19%) and IgD(2%). Two percent of the patients had non-secretory type. 89% of patients were in their stage III of the disease. 2. Among the 45 patients, 96% had abnormal plain radiographic findings with average number of 4.5 lesions. Common sites were the spine, rib, skull, pelvis, and humerus in descending orders. The findings were localized or diffuse osteolytic bone destruction(85%). osteoporosis(49%), pathologic fracture and endosteal scalloping(55%). Osteoporosis was more prominent in stage III than stage II. 3. Both plain X-ray and radioisotope study was available for comparison in 28 patients. Concordance between the two studies were 44%, lesions detected only on plain X-ray film were 51%, and lesions detected only on the radioisotope were 5%. The plain radiography was able to detect only 54% of bone lesions confirmed by bone marrow biopsy. With the above results, accurate evaluation of bone lesions in multiple myeloma may be difficult with radiologic studies only. But familiarity with these radiologic findings of the this disease entity is necessary for early suspicion of the disease, thus for early diagnosis and treatment.

    Multiple myeloma is a clonal plasma cell malignancy within the bone marrow associated with bone loss, renal disease and immunodeficiency. Despite new insights into the pathogenesis of multiple myeloma and novel targeted therapies, the median survival remains 3-5 years. It is now well established that the intimate relation between the tumor cells and components of the microenvironment plays a key role in multiple myeloma pathogenesis. Specifically, tumor cells impact the bone marrow and thereby cause immune suppression and lytic bone lesions; conversely, components of the bone marrow provide signals that influence the behavior of multiple myeloma cells, including tumor cell growth, survival, migration and drug resistance. Important contributing effectors are tumor cell-stroma cell and cell-extracellular matrix contacts, the bone marrow vasculature, and a variety of cytokines and growth factors in the bone marrow milieu.

    2003-01-01

    To study the expression of beta-human chorionic gonadotropin (βhCG) genes in renal cellcarcinomas (RCC) and benign renal disease tissues, nested reverse transcription-polymerase chainreaction (RT-PCR) and restriction endonuclease analysis were employed to detect the expression ofβhCG genes in 44 cases of RCC tissues and 24 cases of benign renal disease tissues. It was foundthat 52% RCC samples revealed positive for βhCG mRNA expression. Positive rate in advancedstage and poorly differentiated RCC was higher, but there was no significant difference. The posi-tive rate of βhCG mRNA expression was 54% in 24 cases of benign renal tissues, including 3 casesout of 6 polycystic kidneys, 7 cases out of 13 renal atrophies, 2 cases out of 2 oncocytomas and 1case out of 2 pyonephrotic kidneys. β7 was most frequently transcribed subtype gene independent onthe histology. These findings suggested βhCG gene transcription is not only involved in RCC but al-so in benign renal diseases.

    Great improvements in diagnostics and treatment for malignant disease in childhood have led to a major increase in survival. However, childhood cancer survivors (CCS) are at great risk for developing adverse effects caused by multimodal treatment for their malignancy. Nephrotoxicity is one of these known (acute) side effects of several treatments, including cisplatin, carboplatin, ifosfamide, radiotherapy and nephrectomy, and can cause glomerular filtration rate impairment, proteinuria, tubulopathy and hypertension. However, evidence about the long-term effects of these treatments on renal function remains inconclusive. To reduce the number of (long-term) nephrotoxic events in CCS, it is important to know the risk of, and risk factors for, early and late renal adverse effects, so that ultimately treatment and screening protocols can be adjusted. To evaluate existing evidence on the effects of potentially nephrotoxic treatment modalities on the prevalence of and associated risk factors for renal dysfunction in survivors treated for childhood cancer with a median or mean survival of at least one year after cessation of treatment, where possible in comparison with healthy controls or CCS treated without potentially nephrotoxic treatment. We searched the following electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 4, 2011), MEDLINE/PubMed (from 1945 to December 2011) and EMBASE/Ovid (from 1980 to December 2011). With the exception of case reports, case series and studies including fewer than 20 participants, we included studies with all study designs that reported on renal function (one year or longer after cessation of treatment) in children and adults who were treated for a paediatric malignancy (aged 18 years or younger at diagnosis) with cisplatin, carboplatin, ifosfamide, radiation including the kidney region and/or a nephrectomy.

  14. Destabilization of Akt Promotes the Death of Myeloma Cell Lines

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Constitutive activation of Akt is believed to be an oncogenic signal in multiple myeloma and is associated with poor patient prognosis and resistance to available treatment. The stability of Akt proteins is regulated by phosphorylating the highly conserved turn motif (TM of these proteins and the chaperone protein HSP90. In this study we investigate the antitumor effects of inhibiting mTORC2 plus HSP90 in myeloma cell lines. We show that chronic exposure of cells to rapamycin can inhibit mTORC2 pathway, and AKT will be destabilized by administration of the HSP90 inhibitor 17-allylamino-geldanamycin (17-AAG. Finally, we show that the rapamycin synergizes with 17-AAG and inhibits myeloma cells growth and promotes cell death to a greater extent than either drug alone. Our studies provide a clinical rationale of use mTOR inhibitors and chaperone protein inhibitors in combination regimens for the treatment of human blood cancers.

    A major part of the wineries' wastes is composed of grape stems which are discarded mainly in open fields and cause environmental problems due mainly to their high polyphenolic content. The grape stem extracts' use as a source of high added value polyphenols presents great interest because this combines a profitable venture with environmental protection close to wine-producing zones. In the present study, at first, the Total Polyphenolic Content (TPC) and the polyphenolic composition of grape stem extracts from four different Greek Vitis vinifera varieties were determined by HPLC methods. Afterwards, the grape stem extracts were examined for their ability to inhibit growth of colon (HT29), breast (MCF-7 and MDA-MB-23), renal (786-0 and Caki-1) and thyroid (K1) cancer cells. The cancer cells were exposed to the extracts for 72 h and the effects on cell growth were evaluated using the SRB assay. The results indicated that all extracts inhibited cell proliferation, with IC₅₀ values of 121-230 μg/ml (MCF-7), 121-184 μg/ml (MDA-MD-23), 175-309 μg/ml (HT29), 159-314 μg/ml (K1), 180-225 μg/ml (786-0) and 134->400 μg/ml (Caki-1). This is the first study presenting the inhibitory activity of grape stem extracts against growth of colon, breast, renal and thyroid cancer cells. Copyright © 2014 Elsevier Ireland Ltd.

    Carfilzomib (CFZ), an epoxyketone with specific chymotrypsin-like activity, is a second-generation proteasome inhibitor with significant activity in patients with relapsed and refractory multiple myeloma. On July 20, 2012, the US Food and Drug Administration approved CFZ to treat patients with multiple myeloma who have received at least two prior therapies including bortezomib (BORT) and an immunomodulatory agent and have demonstrated disease progression on or within 60 days of completion of the last therapy. Cytogenetic abnormalities did not appear to have a significant impact on the CFZ activity. Carfilzomib was well tolerated and demonstrated promising efficacy in patients with renal insufficiency. Pomalidomide (POM) (CC-4047) is a novel immunomodulatory derivative (IMID) with a stronger in vitro anti-myeloma effect compared with "older" IMIDs - thalidomide and lenalidomide (LEN). On February 8, 2013, the US Food and Drug Administration approved POM (Pomalyst, Celgene) for the treatment of MM patients who have received at least two prior therapies including LEN and BORT and have demonstrated progression on or within 60 days of completion of the last therapy. Pomalidomide is a novel IMID with significant anti-myeloma activity and manageable toxicity. This compound has shown high efficacy in MM patients who were resistant to prior use of LEN/BORT as well as in patients with a high-risk cytogenetic profile. Carfilzomib and POM have very high efficacy and will be used also in first line therapy in future.

    Surgical treatment was conducted in 81 patients, suffering renocellular cancer (RCC), complicated by a renal vein and vena cava inferior thrombosis. According to the Mayo clinic classification, the level of a tumoral thrombus spread was established: the 0 level--in 37 patients, the level I--in 19, the level II--in 17, the level III --in 6, and the level IV--in 2. There were substantiated the optimal surgical accesses and technique of radical nephrectomy and thrombectomy for RCC, complicated by a renal vein and vena cava inferior thrombosis. It is recommended to apply transabdominal accesses: the extended median laparotomic, bilateral subcostal of a "Chevron" or "Mercedes" type. There was shown, that the access choice depends on the level of the tumoral thrombus localization.

    The incidence and mortality of site-specific cancers in patients with end-stage renal disease (ESRD) on maintenance dialysis have been rarely studied for Asian populations. We tapped Taiwan`s National Health Insurance Research Database to identify and recruit patients starting maintenance dialysis between 1999 and 2004. They were followed from initiation of dialysis until death, discontinuation of dialysis, or the end of 2008. We calculated the survival rate and mortality risk of dialysis patients with cancer. Of 40,833 dialysis patients, 2352 (5.8%) had been newly diagnosed with cancer. Being older, being male, and having chronic liver disease were factors associated with a higher risk for new cancer in ESRD dialysis patients. In men, liver cancer (20.63%) was the most frequent, followed by cancers of the bladder (16.88%) and kidney (11.61%). In women, bladder cancer (25.57%) was the most frequent, followed by cancers of the kidney (16.31%) and breast (11.20%). The 5-year survival rates for kidney and bladder cancer were higher than for other cancers; the survival rates for lung, stomach, and liver cancer were lower. In conclusion, the distribution of site-specific cancer was different between men and women in patients with ESRD on dialysis. More attention should be paid to teaching dialysis patients how to avoid the well-known cancer risks and carcinogens and individualized regular cancer screenings. PMID:28123593

  8. Evolving diagnostic criteria for multiple myeloma.

    Multiple myeloma (MM) is a plasma cell malignancy historically defined by the presence of end-organ damage, specifically, hypercalcemia, renal failure, anemia, and bone lesions (CRAB features) that can be attributed to the neoplastic process. In 2014, the International Myeloma Working Group (IMWG) updated the diagnostic criteria for MM to add specific biomarkers that can be used to make the diagnosis of the disease in patients who did not have CRAB features. In addition, the update allows modern imaging methods including computed tomography (CT) and positron emission tomography-CT to diagnose MM bone disease. These changes enable early diagnosis, and allow the initiation of effective therapy to prevent the development of end-organ damage in patients who are at the highest risk. This article reviews these and several other clarifications and revisions that were made to the diagnostic criteria for MM and related disorders. The updated disease definition for MM also automatically resulted in a revision to the diagnostic criteria for the asymptomatic phase of the disease termed smoldering MM (SMM). Thus the current diagnosis and risk-stratification of SMM is also reviewed in this article. Using specific prognostic factors, it is possible to identify a subset of patients with SMM who have a risk of progression to MM of 25% per year (high-risk SMM). An approach to the management of patients with low- and high-risk SMM is discussed.

    The purpose of this paper is to investigate the feasibility of using a similarity coefficient map (SCM) in improving the morphological evaluation of T2* weighted (T2*W) magnatic resonance imaging (MRI) for renal cancer.Simulation studies and in vivo 12-echo T2*W experiments for renal cancers were performed for this purpose.The results of the first simulation study suggest that an SCM can reveal small structures which are hard to distinguish from the background tissue in T2*W images and the corresponding T2* map.The capability of improving the morphological evaluation is likely due to the improvement in the signal-to-noise ratio (SNR) and the carrier-to-noise ratio (CNR) by using the SCM technique.Compared with T2*W images,an SCM can improve the SNR by a factor ranging from 1.87 to 2.47.Compared with T2* maps,an SCM can improve the SNR by a factor ranging from 3.85 to 33.31.Compared with T2*W images,an SCM can improve the CNR by a factor ranging from 2.09 to 2.43.Compared with T2* maps,an SCM can improve the CNR by a factor ranging from 1.94 to 8.14.For a given noise level,the improvements of the SNR and the CNR depend mainly on the original SNRs and CNRs in T2*W images,respectively.In vivo experiments confirmed the results of the first simulation study.The results of the second simulation study suggest that more echoes are used to generate the SCM,and higher SNRs and CNRs can be achieved in SCMs.In conclusion,an SCM can provide improved morphological evaluation of T2*W MR images for renal cancer by unveiling fine structures which are ambiguous or invisible in the corresponding T2*W MR images and T2* maps.Furthermore,in practical applications,for a fixed total sampling time,one should increase the number of echoes as much as possible to achieve SCMs with better SNRs and CNRs.

    Aims To estimate the incidence of chronic dialysis in patients with a history of cancer and assess how renal replacement therapy is initiated in this population. Methods We merged data from cancer registries and hospital databases in one French region to identify patients with an incident cancer between 2001 and 2008 who started chronic dialysis. Results Mean participation time was 3.4 ± 2.7 years. Males comprised 58.5 % of participants. During the study period, 74 chronic dialysis treatments were initiated. Chronic interstitial nephritis was the leading cause of end-stage renal disease (21.6 %), and 46.6 % of dialysis initiation cases were unplanned. The incidence rate of chronic dialysis initiation in the population of incident cancer patients was 370 per million population/year (74 events/199,809 person-years). After age-adjustment, the standardized incidence ratio was 1.26, 95 % confidence interval 0.98-1.57, p = 0.55. Conclusion Cancer patients are known to be at risk of chronic kidney disease. However, the standardized incidence ratio of chronic dialysis initiation did not differ significantly between cancer patients and the general population. Further studies should be performed to identify the barriers to starting renal replacement therapy in cancer patients.

    Multiple myeloma (MM) is a hematologic malignancy of monoclonal plasma cells which remains incurable despite recent advances in therapies. The presence of cancer stem cells (CSCs) has been demonstrated in many solid and hematologic tumors, so the idea of CSCs has been proposed for MM, even if MM CSCs have not been define yet. The existence of myeloma CSCs with clonotypic B and clonotypic non B cells was postulated by many groups. This review aims to focus on these distinct clonotypic subpopulations and on their ability to develop and sustain MM. The bone marrow microenvironment provides to MM CSCs self-renewal, survival and drug resistance thanks to the presence of normal and cancer stem cell niches. The niches and CSCs interact each other through adhesion molecules and the interplay between ligands and receptors activates stemness signaling (Hedgehog, Wnt and Notch pathways). MM CSCs are also supposed to be responsible for drug resistance that happens in three steps from the initial cancer cell homing microenvironment-mediated to development of microenvironment-independent drug resistance. In this review, we will underline all these aspects of MM CSCs.

    Nonmelanoma skin cancer (NMSC) is the most common malignancy in patients who have received a solid organ transplant. Multiple factors are involved in the onset of posttransplant NMSC. To analyze the relationship between new immunosuppressive drugs and the onset of NMSC in renal transplant recipients. This was a combined retrospective and prospective observational study in which we studied 289 patients who received a kidney transplant between January 1996 and December 2010 at Hospital Universitario Doctor Peset in Valencia, Spain. Seventy-three patients (25.2%) developed 162 NMSCs over a median follow-up of 72 months. There were no statistically significant differences in the onset of NMSC on comparing different induction therapy strategies involving monoclonal and polyclonal antibodies. NMSCs occurred less frequently in patients treated with mammalian target of rapamycin (mTOR) inhibitors than in those treated with other immunosuppressive regimens, although the differences were not statistically significant. Three of 5 patients with recurrent NMSC who were switched from calcineurin inhibitors to mTOR inhibitors developed additional NMSCs despite the change. Induction therapy with monoclonal and polyclonal antibodies in renal transplant recipients is not associated with an increased risk of NMSC. While mTOR inhibitors are associated with a lower risk of posttransplant NMSC, it remains to be determined whether a switch to these drugs is useful in the management of patients who develop multiple NMSCs.

    Full Text Available Introduction. Partial nephrectomy (PN is playing an increasingly important role in localized renal cell carcinoma (RCC as a true alternative to radical nephrectomy. With the greater experience and expertise of surgical teams, it has become an alternative to radical nephrectomy in young patients when the tumor diameter is 4 cm or less in almost all hospitals since cancer-specific survival outcomes are similar to those obtained with radical nephrectomy. Materials and Methods. The authors comment on their own experience and review the literature, reporting current indications and outcomes including complications. The surgical technique of open partial nephrectomy is outlined. Conclusions. Nowadays, open PN is the gold standard technique to treat small renal masses, and all nonablative techniques must pass the test of time to be compared to PN. It is not ethical for patients to undergo radical surgery just because the urologists involved do not have adequate experience with PN. Patients should be involved in the final treatment decision and, when appropriate, referred to specialized centers with experience in open or laparoscopic partial nephrectomies.

    It has been well-characterized that the renin-angiotensin system (RAS) physiologically regulates systemic arterial pressure. However, RAS signaling has also been shown to increase cell proliferation during malignancy, and angiotensin receptor blockers (ARBs) are able to decrease pro-survival signaling by inhibiting anti-apoptotic molecules and suppressing caspase activity. In this study, the apoptotic effects of telmisartan, a type of ARB, was evaluated using a non-cancerous human renal cell line (HEK) and a human renal cell carcinoma (RCC) cell line (786). Both types of cells were treated with telmisartan for 4 h, 24 h, and 48 h, and then were assayed for levels of apoptosis, caspase-3, and Bcl-2 using MTT assays, flow cytometry, and immunostaining studies. Analysis of variance was used to identify significant differences between these data (P telmisartan, a marked inhibition of cell proliferation was observed. 50 µM cisplatin also caused high inhibition of these cells. Moreover, these inhibitions were both concentration- and time-dependent (P telmisartan did not produce an apoptotic effect compared with control cells at the 24 h timepoint (P > 0.05).

    Full Text Available Serine and arginine rich splicing factor 2(SRSF2 belongs to the serine/arginine (SR-rich family of proteins that regulate alternative splicing. Previous studies suggested that SRSF2 can contribute to carcinogenic processes. Clear cell renal cell carcinoma (ccRCC is the most common subtype of kidney cancer, highly aggressive and difficult to treat, mainly due to resistance to apoptosis. In this study we hypothesized that SRSF2 contributes to the regulation of apoptosis in ccRCC. Using tissue samples obtained from ccRCC patients, as well as independent validation on The Cancer Genome Atlas (TCGA data, we demonstrate for the first time that expression of SRSF2 is decreased in ccRCC tumours when compared to non-tumorous control tissues. Furthermore, by employing a panel of ccRCC-derived cell lines with silenced SRSF2 expression and qPCR arrays we show that SRSF2 contributes not only to splicing patterns but also to expression of multiple apoptotic genes, including new SRSF2 targets: DIABLO, BIRC5/survivin, TRAIL, BIM, MCL1, TNFRSF9, TNFRSF1B, CRADD, BCL2L2, BCL2A1, and TP53. We also identified a new splice variant of CFLAR, an inhibitor of caspase activity. These changes culminate in diminished caspase-9 activity and inhibition of apoptosis. In summary, we show for the first time that decreased expression of SRSF2 in ccRCC contributes to protection of cancer cells viability.

  18. Targeting proliferating cell nuclear antigen and its protein interactions induces apoptosis in multiple myeloma cells.

    Directory of Open Access Journals (Sweden)

    Rebekka Müller

    Full Text Available Multiple myeloma is a hematological cancer that is considered incurable despite advances in treatment strategy during the last decade. Therapies targeting single pathways are unlikely to succeed due to the heterogeneous nature of the malignancy. Proliferating cell nuclear antigen (PCNA is a multifunctional protein essential for DNA replication and repair that is often overexpressed in cancer cells. Many proteins involved in the cellular stress response interact with PCNA through the five amino acid sequence AlkB homologue 2 PCNA-interacting motif (APIM. Thus inhibiting PCNA's protein interactions may be a good strategy to target multiple pathways simultaneously. We initially found that overexpression of peptides containing the APIM sequence increases the sensitivity of cancer cells to contemporary therapeutics. Here we have designed a cell-penetrating APIM-containing peptide, ATX-101, that targets PCNA and show that it has anti-myeloma activity. We found that ATX-101 induced apoptosis in multiple myeloma cell lines and primary cancer cells, while bone marrow stromal cells and primary healthy lymphocytes were much less sensitive. ATX-101-induced apoptosis was caspase-dependent and cell cycle phase-independent. ATX-101 also increased multiple myeloma cells' sensitivity against melphalan, a DNA damaging agent commonly used for treatment of multiple myeloma. In a xenograft mouse model, ATX-101 was well tolerated and increased the anti-tumor activity of melphalan. Therefore, targeting PCNA by ATX-101 may be a novel strategy in multiple myeloma treatment.

    Full Text Available Abstract Background Multiple myeloma is an incurable complex disease characterized by clonal proliferation of malignant plasma cells in a hypoxic bone marrow environment. Hypoxia-dependent erythropoietin (EPO-receptor (EPOR signaling is central in various cancers, but the relevance of EPOR signaling in multiple myeloma cells has not yet been thoroughly investigated. Methods Myeloma cell lines and malignant plasma cells isolated from bone marrow of myeloma patients were used in this study. Transcript levels were analysed by quantitative PCR and cell surface levels of EPOR in primary cells by flow cytometry. Knockdown of EPOR by short interfering RNA was used to show specific EPOR signaling in the myeloma cell line INA-6. Flow cytometry was used to assess viability in primary cells treated with EPO in the presence and absence of neutralizing anti-EPOR antibodies. Gene expression data for total therapy 2 (TT2, total therapy 3A (TT3A trials and APEX 039 and 040 were retrieved from NIH GEO omnibus and EBI ArrayExpress. Results We show that the EPOR is expressed in myeloma cell lines and in primary myeloma cells both at the mRNA and protein level. Exposure to recombinant human EPO (rhEPO reduced viability of INA-6 myeloma cell line and of primary myeloma cells. This effect could be partially reversed by neutralizing antibodies against EPOR. In INA-6 cells and primary myeloma cells, janus kinase 2 (JAK-2 and extracellular signal regulated kinase 1 and 2 (ERK-1/2 were phosphorylated by rhEPO treatment. Knockdown of EPOR expression in INA-6 cells reduced rhEPO-induced phospo-JAK-2 and phospho-ERK-1/2. Co-cultures of primary myeloma cells with bone marrow-derived stroma cells did not protect the myeloma cells from rhEPO-induced cell death. In four different clinical trials, survival data linked to gene expression analysis indicated that high levels of EPOR mRNA were associated with better survival. Conclusions Our results demonstrate for the first time

    Targeted therapies have improved survival in patients with metastatic renal cell cancer (RCC); however, expert opinion on the optimal therapeutic strategy is divided. This retrospective study evaluates different sequential schemes of targeted therapies in 310 patients with advanced/metastatic RCC who received different systemic agents - sorafenib, sunitinib, bevacizumab, everolimus, temsirolimus and axitinib - alone or in different sequences, until disease progression or intolerable toxicity (median follow-up: 37 months). The median overall survival (OS) was 22 months and the 5-year OS was 23.4%; differential therapeutic schemes were not associated with differences in OS. A worse performance status, no nephrectomy and a poor-risk classification according to the Motzer criteria was associated with a shorter OS. These findings support the use of targeted therapies in the treatment of RCC, even in a large unselected population from a single institution, and suggest that treatment should be tailored to meet individual circumstances and needs.

    The critical point for successful treatment of cancer is diagnosis at early stages of tumor development. Cancer cell-specific methylated DNA has been found in the blood of cancer patients, indicating that cell-free DNA (cfDNA) circulating in the blood is a convenient tumor-associated DNA marker. Therefore methylated cfDNA can be used as a minimally invasive diagnostic marker. We analysed the concentration of plasma cfDNA and methylation of six tumor suppressor genes in samples of 27 patients with renal cancer and 15 healthy donors as controls. The cfDNA concentrations in samples from cancer patients and healthy donors was measured using two different methods, the SYBR Green I fluorescence test and quantitative real-time PCR. Both methods revealed a statistically significant increase of cfDNA concentrations in cancer patients. Hypermethylation on cfDNA was detected for the LRRC3B (74.1%), APC (51.9%), FHIT (55.6%), and RASSF1 (62.9%) genes in patients with renal cancer. Promoter methylation of VHL and ITGA9 genes was not found on cfDNA. Our results confirmed that the cfDNA level and methylation of CpG islands of RASSF1A, FHIT, and APC genes in blood plasma can be used as noninvasive diagnostic markers of cancer.

    Full Text Available Multiple myeloma survival has significantly improved in latest years, due to a broad spectrum of novel agents available for treatment. The introduction of thalidomide, bortezomib and lenalidomide together with autologous stem cell transplantation has dramatically prolonged complete remissions rate, progression free survivals resulting ultimately in prolonged survivals in myeloma patients. Moreover, novel strategies of treatment such as consolidation and maintenance are being used to implement responses. A number of new drugs such as carfilzomib and pomalidomide are already in clinical practice, and new kids on the block are entering, making the future of myeloma patients brighter.

    Metastatic renal cell carcinoma can be clinically diverse in terms of the pattern of metastatic disease and response to treatment. We studied the impact of metastasis and location on cancer specific survival. The records of 2,017 patients with renal cell cancer and tumor thrombus who underwent radical nephrectomy and tumor thrombectomy from 1971 to 2012 at 22 centers in the United States and Europe were analyzed. Number and location of synchronous metastases were compared with respect to patient cancer specific survival. Multivariable Cox regression models were used to quantify the impact of covariates. Lymph node metastasis (155) or distant metastasis (725) was present in 880 (44%) patients. Of the patients with distant disease 385 (53%) had an isolated metastasis. The 5-year cancer specific survival was 51.3% (95% CI 48.6-53.9) for the entire group. On univariable analysis patients with isolated lymph node metastasis had a significantly worse cancer specific survival than those with a solitary distant metastasis. The location of distant metastasis did not have any significant effect on cancer specific survival. On multivariable analysis the presence of lymph node metastasis, isolated distant metastasis and multiple distant metastases were independently associated with cancer specific survival. Moreover higher tumor thrombus level, papillary histology and the use of postoperative systemic therapy were independently associated with worse cancer specific survival. In our multi-institutional series of patients with renal cell cancer who underwent radical nephrectomy and tumor thrombectomy, almost half of the patients had synchronous lymph node or distant organ metastasis. Survival was superior in patients with solitary distant metastasis compared to isolated lymph node disease. Copyright © 2015 American Urological Association Education and Research, Inc.

    Full Text Available Smoldering multiple myeloma (SMM is an asymptomatic precursor stage of multiple myeloma (MM characterized by clonal bone marrow plasma cells (BMPC ≥ 10% and/or M protein level ≥ 30 g/L in the absence of end organ damage. It represents an intermediate stage between monoclonal gammopathy of undetermined significance (MGUS and symptomatic MM. The risk of progression to symptomatic MM is not uniform, and several parameters have been reported to predict the risk of progression. These include the level of M protein and the percentage of BMPC, the proportion of immunophenotypically aberrant plasma cells, and the presence of immunoparesis, free light-chain (FLC ratio, peripheral blood plasma cells (PBPC, pattern of serum M protein evolution, abnormal magnetic resonance imaging (MRI, cytogenetic abnormalities, IgA isotype, and Bence Jones proteinuria. So far treatment is still not recommended for SMM, because several trials suggested that patients with SMM do not benefit from early treatment. However, the Mateos et al. trial showed a survival benefit after early treatment with lenalidomide plus dexamethasone in patients with high-risk SMM. This trial has prompted a reevaluation of early treatment in an asymptomatic patient population.

    Renal cell cancer is the most frequent malignant tumor of the kidney. Depending on tumor size, extension and general condition, radical or partial nephrectomy, which meanwhile can be performed laparoscopically, is still the therapy of choice. Patients with an increased surgical risk, or suffering from additional renal tumors or tumor in a single kidney, percutaneous tumor ablation is a helpful therapeutical option. Among all thermal ablation procedures, most experiences exist with radiofrequency ablation (RFA). A significant advantage of this technique is the possibility of direct puncture of the tumor without Seldinger technique and track ablation. This helps to reduce the risk of bleeding and tumor seeding within the puncture track. By use of modern ablation probes, lesions of up to 5 cm diameter can be created without repositioning of the probe. Initial superselective particle embolization is recommended in tumors beyond 3 cm in size, because renal cell cancer is often hypervascularized and devasularization helps to reduce ablation time. Furthermore, the tumor location within the kidney is influencing the ablation result. Exophytically growing lesions or tumors within the renal parenchyma can be treated with a safety margin. Tumors in a central location or with broad contact to the collecting system are no candidates for thermal ablation, because of an increased risk of thermal collateral damage. Computed tomography is an optimal imaging modality and crucial to planning, performing and controlling of a successful percutaneous RFA. Based on the previous experiences of 300 published cases, renal RFA results in an over 90% success rate associated with a low complication rate. A randomized controlled study comparing RFA and surgery is necessary to answer the question whether RFA can be considered therapy of first choice even for patients, who are according to the actual evidence surgical candidates.

    Auto-immun events are rare in multiple myeloma (MM). Here, we report one MM case complicated by Evans syndrome (Autoimmun hemolytic anemia (AIHA) associated with thrombocytopenia). A 52-year-old man was admitted in nephrology department with severe anemia, renal insufficiency and hypergamma globulinemia. Laboratory exams showed acute hemolysis due to an IgG warm autoantibody. Serum electrophoresis revealed the presence of a monoclonal IgG protein and urinary M protein was 2g/day. A whole body CT-Scan showed osteolytic lesions of vertebral body of C5, D4, L3, L4 and the left iliac wing. The diagnosis of multiple myeloma and Evan's syndrome was made, we underwent chemotherapy by BTD (bortezomib-thalidomide-dexamethasone) and continuous corticosteroid therapy but unfortunately the patient died secondary of a Lactic acidosis. The relationship between MM and hemolysis remain unclear.

    Purpose: We study CD38 levels in immunosuppressive CD4(+)CD25(high)Foxp3(+) regulatory T cells (Treg) and further define immunomodulating effects of a therapeutic CD38 mAb isatuximab/SAR650984 in multiple myeloma.Experimental Design: We evaluated percentages of CD38-expressing subsets in Tregs from normal donors and multiple myeloma patients. Peripheral blood mononuclear cells (PBMC) were then treated with isatuximab with or without lenalidomide or pomalidomide to identify their impact on the percentage and immunosuppressive activity of Tregs on CD4(+)CD25(-) T cells (Tcons). We investigated the mechanism of increased Tregs in multiple myeloma patients in ex vivo cocultures of multiple myeloma cells with PBMCs or Tcons.Results: CD38 expression is higher on Tregs than Tcons from multiple myeloma patients versus normal donors. CD38 levels and the percentages of CD38(high) Tregs are increased by lenalidomide and pomalidomide. Isatuximab preferentially decreases Treg and increases Tcon frequencies, which is enhanced by pomalidomide/lenalidomide. Isatuximab reduces Foxp3 and IL10 in Tregs and restores proliferation and function of Tcons. It augments multiple myeloma cell lysis by CD8(+) T and natural killer cells. Coculture of multiple myeloma cells with Tcons significantly induces Tregs (iTregs), which express even higher CD38, CD25, and FoxP3 than natural Tregs. This is associated with elevated circulating CD38(+) Tregs in multiple myeloma patients versus normal donors. Conversely, isatuximab decreases multiple myeloma cell- and bone marrow stromal cell-induced iTreg by inhibiting both cell-cell contact and TGFβ/IL10. Finally, CD38 levels correlate with differential inhibition by isatuximab of Tregs from multiple myeloma versus normal donors.Conclusions: Targeting CD38 by isatuximab can preferentially block immunosuppressive Tregs and thereby restore immune effector function against multiple myeloma.

    Full Text Available The authors report a case of a 62-year-old female with history of multiple myeloma who presents with complains of swelling and pain in her right eye. On examination, it was found that she has proptosis, chemosis, and diplopia along with decreased vision. Initial workup and treatment did not yield significant results, eventually she was found to have myelomatous changes in her right orbit on MRI and was diagnosed with multiple myeloma of the orbit which resolved solely with radiation. This case tends to highlight the importance of considering myeloma of the orbit as a very important and early differential diagnosis in a patient with a history of multiple myeloma presenting with a swollen and painful eye.

    Full Text Available Renal infarction is a rare cause of acute kidney injury which could lead to permanent loss of renal function. A prompt diagnosis is necessary in order to achieve a successful revascularization of the occluded artery. Given the rarity of the disease and the paucity of the reported cases in the previous literature a high index of suspicion must be maintained not only in the classical cardiac sources of systemic emboli (atrial fibrillation, dilated cardiomyopathy, or endocarditis, but also in the situations when a hypercoagulable state is presumed. The unspecific presenting symptoms often mask the true etiology of the patient’s complaints. We present here a rare case of renal infarction that occurred in the setting of a hypercoagulable state, in a female patient with a history of breast cancer and documented hepatic metastases.

    Full Text Available Abstract Background Angiostatic/antiinflammatory therapy with COX-II inhibitors and pioglitazone seems to be a well tolerated and promising regimen in patients with metastatic cancer. COX-II inhibitors may have less gastrointestinal side effects than conventional non-steroidal antiinflammatory drugs, but their impact on renal function seems to be similar. Methods 87 patients with metastatic/advanced cancer were treated up to 12 months (mean 19.5 weeks with rofecoxib, pioglitazone and either capecitabine (group A with gastrointestinal and urological cancer, n = 50 or trofosfamide (group B with non-gastrointestinal/non-urological cancer, n = 37 and followed for further 6 months. Results Baseline serum creatinine concentration was 0.81 ± 0.28 mg/dl, and increased by about 0.15 mg/dl during months 1-3. Accordingly estimated glomerular filtration rate (eGFR decreased from 90.3 ml/min ± 3.6 ml/min at baseline by about 10 ml/min during months 1-3. Renal function decreased in 75 patients (86% in the first month (p Conclusions Therapy with rofecoxib in an antiangiogenic/antiinflammatory setting results in a decrease of renal function in nearly every patient.

    In this study, an attempt has been made to identify expression-based gene biomarkers that can discriminate early and late stage of clear cell renal cell carcinoma (ccRCC) patients. We have analyzed the gene expression of 523 samples to identify genes that are differentially expressed in the early and late stage of ccRCC. First, a threshold-based method has been developed, which attained a maximum accuracy of 71.12% with ROC 0.67 using single gene NR3C2. To improve the performance of threshold-based method, we combined two or more genes and achieved maximum accuracy of 70.19% with ROC of 0.74 using eight genes on the validation dataset. These eight genes include four underexpressed (NR3C2, ENAM, DNASE1L3, FRMPD2) and four overexpressed (PLEKHA9, MAP6D1, SMPD4, C11orf73) genes in the late stage of ccRCC. Second, models were developed using state-of-art techniques and achieved maximum accuracy of 72.64% and 0.81 ROC using 64 genes on validation dataset. Similar accuracy was obtained on 38 genes selected from subset of genes, involved in cancer hallmark biological processes. Our analysis further implied a need to develop gender-specific models for stage classification. A web server, CancerCSP, has been developed to predict stage of ccRCC using gene expression data derived from RNAseq experiments. PMID:28349958

    In May and September, 2002, 14 private residential drinking water wells, one dewatering well at a lignite mine, eight surface water sites, and lignite from an active coal mine were sampled in five Parishes of northwestern Louisiana, USA. Using a geographic information system (GIS), wells were selected that were likely to draw water that had been in contact with lignite; control wells were located in areas devoid of lignite deposits. Well water samples were analyzed for pH, conductivity, organic compounds, and nutrient and anion concentrations. All samples were further tested for presence of fungi (cultures maintained for up to 28 days and colonies counted and identified microscopically) and for metal and trace element concentration by inductively-coupled plasma mass spectrometry and atomic emission spectrometry. Surface water samples were tested for dissolved oxygen and presence of pathogenic leptospiral bacteria. The Spearman correlation method was used to assess the association between the endpoints for these field/laboratory analyses and incidence of cancer of the renal pelvis (RPC) based on data obtained from the Louisiana Tumor Registry for the five Parishes included in the study. Significant associations were revealed between the cancer rate and the presence in drinking water of organic compounds, the fungi Zygomycetes, the nutrients PO{sub 4} and NH{sub 3}, and 13 chemical elements. Presence of human pathogenic leptospires was detected in four out of eight (50%) of the surface water sites sampled.

    Autophagy plays an important role in plasma cell ontogeny and in the pathophysiology of multiple myeloma. Autophagy is usually considered a pro-survival mechanism, and cooperates with the ubiquitin proteasome system in maintaining the homeostasis of myeloma cells by degrading excessive and misfolded proteins for energy recycling. Therefore, the inhibition of autophagy could effectively induce death in myeloma cells, and could synergize with proteasome inhibitors. However, the excessive activation of autophagy could also lead to the extreme degradation of the organelles that induce autophagic cell death. Hence, the activation of autophagic cell death might also represent a promising approach for treating myeloma. Recent studies have demonstrated that autophagy also mediates drug resistance in myeloma cells and the complications of myeloma, while the inhibition of autophagy may reverse the response to drugs. In this study, we have mainly reviewed recent research on autophagy in relationship to the therapeutic effect, the reversal of drug resistance, and the mediation of complications. Copyright © 2017.

    Cancer cells are frequently addicted to deregulated oncogenic protein translation. The small molecule 4EG-I selectively inhibits the cap-dependent translation of mRNAs. As multiple myeloma is an incurable disease that requires new therapeutic approaches, we investigated whether targeting the translation initiation pathway could be a target for myeloma therapy. Six myeloma cell lines and primary samples were included in this study. The 4EGI-1 effect was determined by AnnexinV staining and caspase activation. Modification of Bcl-2 protein expression was analysed, and the significance of modified proteins was analysed by knock-down experiments. We demonstrated that 4EGI-1 impaired the assembly of the eIF4F complex and decreased the expression of the eIF4E-regulated proteins in myeloma cells. Furthermore, we showed that 4EGI-1 induced strong apoptosis in five out of six myeloma cell lines. Apoptosis is associated with the activation of the intrinsic mitochondrial pathway. The 4EGI-1 triggered Noxa induction only in cells undergoing apoptosis through endoplasmic reticulum (ER) stress. Furthermore, Noxa silencing prevented myeloma cells from 4EGI-1-induced apoptosis. Finally, Noxa induction led to a disruption of Mcl-1/Bim complexes in parallel to the generation of 'Mcl-1-free Noxa'. Our results suggested that the use of inhibitors that directly target the translation initiation complex eIF4F could represent a potential novel approach for multiple myeloma therapy.

    Highlights: • miR-183 was up-regulated in renal cancer tissues. • Inhibition of endogenous miR-183 suppressed renal cancer cell growth and metastasis. • miR-183 increased cell growth and metastasis. • miR-183 regulated renal cancer cell growth and metastasis via directly targeting tumor suppressor protein phosphatase 2A. - Abstract: The aim of this study was to investigate the function of miR-183 in renal cancer cells and the mechanisms miR-183 regulates this process. In this study, level of miR-183 in clinical renal cancer specimens was detected by quantitative real-time PCR. miR-183 was up- and down-regulated in two renal cancer cell lines ACHN and A498, respectively, and cell proliferation, Caspase 3/7 activity, colony formation, in vitro migration and invasion were measured; and then the mechanisms of miR-183 regulating was analyzed. We found that miR-183 was up-regulated in renal cancer tissues; inhibition of endogenous miR-183 suppressed in vitro cell proliferation, colony formation, migration, and invasion and stimulated Caspase 3/7 activity; up-regulated miR-183 increased cell growth and metastasis and suppressed Caspase 3/7 activity. We also found that miR-183 directly targeted tumor suppressor, specifically the 3′UTR of three subunits of protein phosphatase 2A (PP2A-Cα, PP2A-Cβ, and PP2A-B56-γ) transcripts, inhibiting their expression and regulated the downstream regulators p21, p27, MMP2/3/7 and TIMP1/2/3/4. These results revealed the oncogenes role of miR-183 in renal cancer cells via direct targeting protein phosphatase 2A.

    Renal cell carcinoma (RCC) is a rare disease in children and adolescents. This study aimed to review epidemiologic characteristics and survival for pediatric RCC patients using a large, population-based database. The California Cancer Registry (CCR) was reviewed from 1988 to 2004. All cases of RCC in patients younger than 21 years were identified and annual age-adjusted incidence rates were determined for the overall population and subdivided by ethnicity. Tumors were classified by stage and grade, and actuarial mortality rates were calculated. From 1988 to 2004, 43 cases of RCC were identified in patients younger than 21 years, accounting for 4.3% of all renal tumors in this age group. The overall annual age-adjusted incidence was 0.01/100,000 with the tumor more common in non-Hispanic blacks (0.03/100,000) compared to non-Hispanic whites (0.01/100,000), Hispanics (Pacific Islanders (<0.01/100,000). The mean age at presentation was 15.4 years (SD 4.03, SE 0.615). RCC was identified more frequently in females (58.14%). At the time of presentation, 53.49% of tumors were localized, 20.93% were regionally advanced, and 25.58% were metastatic. The observed actuarial survival at 5 and 10 years was 61% (+/-15.7%). Pediatric RCC is an uncommon and aggressive tumor that occurs most frequently in children in the second decade of life, more often in females and blacks. The epidemiological characteristics of this tumor differ from adult RCC and Wilms tumor, suggesting its distinctive biology and potential need for alternative treatment strategies.

    Heparan sulfate-specific endosulfatase-2 (SULF-2) can modulate the signaling of heparan sulfate proteoglycan-binding proteins. The involvement of SULF-2 in cancer growth varies by cancer type. The roles of SULF-2 expression in the progression and prognosis of renal cell carcinomas (RCC) have not yet been fully clarified. In the present study, the expression levels of SULF-2 mRNA and protein in 49 clinical RCC samples were determined by RT-PCR and immunostaining. The existence of RCC with higher SULF-2 expression and lower SULF-2 expression compared to the adjacent normal kidney tissues was suggested. High SULF-2 expression was correlated with an early clinical stage and less invasive pathological factors. Low SULF-2 expression was correlated with an advanced stage and higher invasive factors. Three-year cancer-specific survival (CSS) for high SULF-2 RCC and low SULF-2 RCC were 100% and 71.4%, respectively (log-rank P = 0.0019), with a significantly shorter CSS observed in low SULF-2 RCC patients. The influence of SULF-2 expression level on Wnt/VEGF/FGF signaling, cell viability and invasive properties was examined in three RCC cell lines, Caki-2, ACHN and 786-O, using a SULF-2 suppression model involving siRNA or a SULF-2 overexpression model involving a plasmid vector. High SULF-2 expression enhanced Wnt signaling and Wnt-induced cell viability, but not cell invasion. In contrast, low levels of SULF-2 expression significantly enhanced both cell invasion and viability through the activation of VEGF/FGF pathways. RCC with lower SULF-2 expression might have a higher potential for cell invasion and proliferation, leading to a poorer prognosis via the activation of VEGF and/or FGF signaling.

    Several studies have shown that more than half of cancer patients have unrecognized renal insufficiency (RI), which is a reduced glomerular filtration rate (GFR) with normal serum creatinine. The aim of this study was to determine whether unrecognized RI is associated with an increased risk for chemotherapy-associated adverse effects in breast cancer patients treated with combined doxorubicin and cyclophosphamide treatment. GFR was estimated for 95 breast cancer patients from January 2005 to August 2009 using the Cockcroft-Gault formula. Unrecognized RI was defined as GFR less than 75 ml/min/1.73 m and the patients were grouped according to their estimated GFR. Logistic regression models were used to assess the effect of GFR on clinical outcomes. In total, 49 (52%) patients experienced at least one of the following chemotherapy-associated adverse effects during the course of treatment: an episode of neutropenic fever with hospital admission, a delay in chemotherapy treatment for a medical reason, a need for dose adjustment because of toxicity of the chemotherapeutic drugs, and the need for use of granulocyte colony-stimulating factor. The incidence of these adverse effects occurred more frequently in patients with GFR less than 75 compared with patients with GFR at least 75 (64 vs. 42%, odds ratio 5.29, 95% confidence interval 2.10-13.33) and remained statistically significant after adjustment for age, BMI, and initial doses of chemotherapeutic drugs (odds ratio 3.56, 95% confidence interval 1.08-11.67). Neutropenic fever, dose delay, and dose adjustment as separate outcomes occurred more frequently in the GFR less than 75 group but lost statistical significance after adjustment. Our results demonstrate that unrecognized RI is associated with an increased risk for chemotherapy-associated adverse events in this patient population. Further prospective studies are required to determine whether a dose reduction in patients with unrecognized RI reduces adverse effects

    Multiple myeloma (MM) is an incurable plasma cell malignancy and is the second most common hematological cancer. It is characterized by complex, recurrent genetic and epigenetic abnormalities. Recent publications have linked miRNAs, a novel class of gene regulators to cancer including MM. miRNAs are about 20 nucleotide, single strand, non-coding RNAs that repress gene expression by mRNA degradation or translational repression. Aberrant miRNA expression profiles have been described in MM, and their functional roles in MM pathogenesis are being increasingly recognized. This review summarizes the current literature on the role of miRNAs in MM and offers perspectives on future research and utilization of miRNAs in MM management.

    This report of the Working Group on Stereotactic Radiotherapy of the German Society of Radiation Oncology (DEGRO) aims to provide a literature review and practice recommendations for stereotactic body radiotherapy (SBRT) of primary renal cell cancer and primary pancreatic cancer. A literature search on SBRT for both renal cancer and pancreatic cancer was performed with focus on prospective trials and technical aspects for clinical implementation. Data on renal and pancreatic SBRT are limited, but show promising rates of local control for both treatment sites. For pancreatic cancer, fractionated SBRT should be preferred to single-dose treatment to reduce the risk of gastrointestinal toxicity. Motion-compensation strategies and image guidance are paramount for safe SBRT delivery in both tumor entities. SBRT for renal cancer and pancreatic cancer have been successfully evaluated in phase I and phase II trials. Pancreatic SBRT should be practiced carefully and only within prospective protocols due to the risk of severe gastrointestinal toxicity. SBRT for primary renal cell cancer appears a viable option for medically inoperable patients but future research needs to better define patient selection criteria and the detailed practice of SBRT.

    Full Text Available Abstract Background Renal cell carcinoma (RCC is the most common renal neoplasm. Cancer tissue is often characterized by altered energy regulation. Fatty acid-binding proteins (FABP are involved in the intracellular transport of fatty acids (FA. We examined the level of brain-type (B and liver-type (L FABP mRNA and the protein expression profiles of both FABPs in renal cell carcinoma. Methods Paired tissue samples of cancerous and noncancerous kidney parts were investigated. Quantitative RT-PCR, immunohistochemistry and western blotting were used to determine B- and L-FABP in tumor and normal tissues. The tissue microarray (TMA contained 272 clinico-pathologically characterized renal cell carcinomas of the clear cell, papillary and chromophobe subtype. SPSS 17.0 was used to apply crosstables (χ2-test, correlations and survival analyses. Results B-FABP mRNA was significantly up-regulated in renal cell carcinoma. In normal tissue B-FABP mRNA was very low or often not detectable. RCC with a high tumor grading (G3 + G4 showed significantly lower B-FABP mRNA compared with those with a low grading (G1 + G2. Western blotting analysis detected B-FABP in 78% of the cases with a very strong band but in the corresponding normal tissue it was weak or not detectable. L-FABP showed an inverse relationship for mRNA quantification and western blotting. A strong B-FABP staining was present in 52% of the tumor tissues contained in the TMA. In normal renal tissue, L-FABP showed a moderate to strong immunoreactivity in proximal tubuli. L-FABP was expressed at lower rates compared with the normal tissues in 30.5% of all tumors. There was no correlation between patient survival times and the staining intensity of both FABPs. Conclusion While B-FABP is over expressed in renal cell carcinoma in comparison to normal renal tissues L-FABP appears to be reduced in tumor tissue. Although the expression behavior was not related to the survival outcome of the RCC patients

    2001-01-01

    Full Text Available BACKGROUND: Renal cell cancer (RCC is a chemoresistant disease with no active chemotherapeutic agent achieving objective response rates higher than 15%. Clusterin is a cell survival gene that increases in human renal tubular epithelial cells after various states of injury and disease. Downregulation of clusterin, using antisense oligonucleotides (ASO, has recently been shown to increase chemosensitivity in several prostate cancer models. The objectives in this study were to evaluate clusterin expression levels in human RCC and normal kidney tissue, and to test whether clusterin ASO could also enhance chemosensitivity in human RCC Caki-2 cells both in vitro and in vivo. METHODS: Immunohistochemical staining was used to characterize clusterin expression in 67 RCC and normal kidney tissues obtained from radical nephrectomy specimens. Northern blot analysis was used to assess changes in clusterin mRNA expression after ASO and paclitaxel treatment. The effects of combined clusterin ASO and paclitaxel treatment on Caki-2 cell growth was examined using an MTT assay. Athymic mice bearing Caki-2 tumors were treated with clusterin ASO alone, clusterin ASO plus paclitaxel, and mismatch control oligonucleotides plus paclitaxel, over a period of 28 days with measurement of tumor volumes once weekly over 8 weeks. RESULTS: Immunohistochemistry of normal and malignant kidney tissue sections of 67 patients demonstrated positive clusterin staining for almost all RCC (98% and an overexpression, compared to normal tissue, in a majority of RCC (69%. Clusterin ASO, but not mismatch control oligonucleotides, decreased clusterin mRNA expression in Caki-2 cells in a dosedependent and sequence-specific manner. Pretreatment of Caki-2 cells with clusterin ASO significantly enhanced chemosensitivity to paclitaxel in vitro. Characteristic apoptotic DNA laddering was observed after combined treatment with ASO plus paclitaxel, but not with either agent alone. In vivo

    Two key features of myeloma cells are the deregulation of the cell cycle and the dependency on the expression of the BCL2 family of anti-apoptotic proteins. The cell division cycle 7 (CDC7) is an essential S-phase kinase and emerging CDC7 inhibitors are effective in a variety of preclinical cancer models. These compounds also inhibit CDK9 which is relevant for MCL-1 expression. The activity and mechanism of action of the dual CDC7/CDK9 inhibitor PHA-767491 was assessed in a panel of multiple myeloma cell lines, in primary samples from patients, in the presence of stromal cells and in combination with drugs used in current chemotherapeutic regimens. We report that in all conditions myeloma cells undergo cell death upon PHA-767491 treatment and we report an overall additive effect with melphalan, bortezomib and doxorubicin, thus supporting further assessment of targeting CDC7 and CDK9 in multiple myeloma.

    Multiple myeloma is a plasma cell skeletal malignancy. While therapeutic agents such as bortezomib and lenalidomide have significantly improved overall survival, the disease is currently incurable with the emergence of drug resistance limiting the efficacy of chemotherapeutic strategies. Failure to cure the disease is in part due to the underlying genetic heterogeneity of the cancer. Myeloma progression is critically dependent on the surrounding microenvironment. Defining the interactions between myeloma cells and the more genetically stable hematopoietic and mesenchymal components of the bone microenvironment is critical for the development of new therapeutic targets. In this review, we discuss recent advances in our understanding of how microenvironmental elements contribute to myeloma progression and therapeutically, how those elements can or are currently being targeted in a bid to eradicate the disease.

    Occurrence of cancer after renal transplantation remains a major problem, and the second cause of death. We performed a retrospective analysis of first cancer, first skin cancer, and first organ cancer (including posttransplant lymphoproliferative disease [PTLD]) among 1265 cases from 1979 to 2006. The occurrence of cancer was clearly a time-dependent event justifiying the use of Kaplan-Meier survival and Cox regression methods. The 10-year cumulative incidences of first cancer, first skin cancer, and first organ cancer were 24.6%, 14.5%, and 14.5%, respectively. Recipient age was a major, independent risk factor for the 3 endpoints with a 6% increased relative risk for each year increment (P < .0001). Female gender was also a major, independent risk factor, but only for skin cancer (P = .0002). We could not demonstrate any difference between the immunosuppressive drugs used for induction or maintenance therapy, especially between antithymocyte globulin (ATG) vs anti-CD25, cyclosporine vs tacrolimus, and azathioprine vs mycophenolate mofetil. Large cohorts are needed with strict stratifications for recipient age and gender to detect any difference, if any, among the drugs.

    CD163 is preferentially expressed by monocyte/macrophages; however, recent studies using immunohistochemistry (IHC) have reported that some cancer cells also express CD163. In the present IHC study, we investigated CD163 staining of cancer cells and macrophages in clear cell renal cell carcinoma (ccRCC) tissues and determined the relationship between cancer cell CD163 expression and clinical prognosis in patients with ccRCC. IHC for CD163 was performed in ccRCC tissues from 103 patients. CD163-positive cancer cells were detected in 35% of the patients (36/103); however, the positive signals on cancer cells were significantly lower than those on macrophages. CD163-positive cancer cells were preferentially detected in patients with high T classification, and females, and were significantly associated with shortened progression-free survival and a lower overall survival ratio. Notably, a high intensity of CD163-positive macrophage infiltration was detected in the CD163-positive cancer cell-high tumor areas. Although CD163 mRNA was detected in cultured macrophages, no CD163 mRNA was detected in two cultured RCC cell lines. The detailed mechanism by which a positive signal is detected on cancer cells has not been clarified. Detection of the CD163 antigen on cancer cells might be a useful marker for evaluating the clinical course of patients with ccRCC.

On a cellular level, the disease is characterized by complex interactions between tumor cells and the surrounding bone marrow microenvironment. Understanding of the relationship between malignant plasma cells and the microenvironment has sparked ongoing efforts to develop targeted therapeutic agents for treatment of this disease. The successful development of the first-in-class small-molecule proteasome inhibitor bortezomib occurred as a result of these efforts. This review focuses on the rationale for bortezomib therapy in the treatment of patients with newly diagnosed and relapsed MM, important treatment-related side effects, and future directions for use of bortezomib and other, emerging proteasome inhibitors.Keywords: multiple myeloma, bortezomib, stem cell transplantation, peripheral neuropathy

    Multiple myeloma (MM) is a hematologic malignancy ofmonoclonal plasma cells which remains incurable despiterecent advances in therapies. The presence of cancerstem cells (CSCs) has been demonstrated in many solidand hematologic tumors, so the idea of CSCs has beenproposed for MM, even if MM CSCs have not been defineyet. The existence of myeloma CSCs with clonotypicB and clonotypic non B cells was postulated by manygroups. This review aims to focus on these distinctclonotypic subpopulations and on their ability to developand sustain MM. The bone marrow microenvironmentprovides to MM CSCs self-renewal, survival and drugresistance thanks to the presence of normal and cancerstem cell niches. The niches and CSCs interact each otherthrough adhesion molecules and the interplay betweenligands and receptors activate stemness signaling(Hedgehog, Wnt and Notch pathways). MM CSCs arealso supposed to be responsible for drug resistancethat happens in three steps from the initial cancer cellhoming microenvironment-mediated to development ofmicroenvironment-independent drug resistance. In thisreview, we will underline all these aspects of MM CSCs.

  7. Obesity and Cancer

    Weight, weight gain, and obesity account for approximately 20% of all cancer cases. Evidence on the relation of each to cancer is summarized, including esophageal, thyroid, colon, renal, liver, melanoma, multiple myeloma, rectum, gallbladder, leukemia, lymphoma, and prostate in men; and postmenopausal breast and endometrium in women. Different mechanisms drive etiologic pathways for these cancers. Weight loss, particularly among postmenopausal women, reduces risk for breast cancer. Among cancer patients, data are less robust, but we note a long history of poor outcomes after breast cancer among obese women. While evidence on obesity and outcomes for other cancers is mixed, growing evidence points to benefits of physical activity for breast and colon cancers. Dosing of chemotherapy and radiation therapy among obese patients is discussed and the impact on therapy-related toxicity is noted. Guidelines for counseling patients for weight loss and increased physical activity are presented and supported by strong evidence that increased physical activity leads to improved quality of life among cancer survivors. The “Five A's” model guides clinicians through a counseling session: assess, advise, agree, assist, arrange. The burden of obesity on society continues to increase and warrants closer attention by clinicians for both cancer prevention and improved outcomes after diagnosis. PMID:20507889

    Renal cell carcinoma (RCC) is the fifth most common cancer worldwide, and becomes one of the leading causes of genitourinary cancer-related death in both males and females. Genetic alternations, alcohol consumption, occupationally harmful exposure and even obesity are well-established risk factors of RCC. Omentin-1 is a plasma adipokine synthesized in visceral adipose tissue, and its circulating serum concentration alters not only in conditions associated with insulin resistance such as Polycystic Ovary Syndrome (PCOS), but also in colorectal cancer and prostate cancer. To our best knowledge, the relationship between omentin-1 and RCC has not been clarified previously. Thus, we evaluated serum omentin-1 levels in RCC patients in the current matched case-control study. Forty-one patients newly diagnosed with RCC and forty-two healthy controls confirmed by the comprehensive medical examination were assessed. The omentin-1 concentrations were determined via utilizing enzyme-linked immunosorbent assays (ELISA) in the paired groups, in which the patients and healthy controls had no statistically significant differences in gender, age, systolic blood pressure (SBP), diastolic blood pressure (DBP), waist-hip ratio (WHR), estimate glomerular filtration rate (eGFR), body-mass index (BMI) and biochemical parameters. The omentin-1 levels in healthy people were 9.86±1.44ng/mL and the circulating omentin-1 levels were dramatically decreased to 3.62±0.76ng/mL in RCC patients (p<0.001). Besides, we revealed a negative correlation between omentin-1 with WHR (r=-0.261, p=0.017) and BMI (r=-0.310, p=0.004), further indicating BMI was the main influential factor on omentin-1 levels (p=0.0091). Follow-up studies would be conducted to establish the concrete mechanisms underlying the altered circulating levels of omentin-1 and elucidate the interaction between "RCC complex system" and adipose tissues, which may together provide promising and novel pharmacological insights for RCC

    Full Text Available The objectives of this paper are to discuss a rare cause of laryngeal multiple myeloma, to review unique pathologic findings associated with plasma cell neoplasms, to discuss epidemiology, differential diagnosis, and treatment options for plasma cell neoplasms of the larynx. Laryngeal multiple myeloma, also noted in the literature as “metastatic” multiple myeloma, presenting as a de novo laryngeal mass is extremely rare with few reported cases. Laryngeal involvement of extramedullary tumors is reported to be between 6% and 18% with the epiglottis, glottis, false vocal folds, aryepiglottic folds, and subglottis involved in decreasing the order of frequency. We present the case of a 58-year-old male with a history of IgA smoldering myeloma who presented to a tertiary care laryngological practice with a two-month history of dysphonia, which was found to be laryngeal involvement of multiple myeloma. We review the classification of and differentiation between different plasma cell neoplasms, disease workups, pathologic findings, and treatment options.

    Continued improvement of our understanding of the clinical, histologic, and genetic features of renal cell tumors has progressively evolved renal tumor classification, revealing an expanding array of distinct tumor types with different implications for prognosis, patient counseling, and treatment. Although clear cell renal cell carcinoma is unequivocally the most common adult renal tumor, there is growing evidence that some "clear cell" renal neoplasms, such as exemplified by multilocular cystic clear cell renal neoplasm of low malignant potential (formerly multilocular cystic renal cell carcinoma), do not have the same potential for insidious progression and metastasis, warranting reclassification as low malignant potential tumors or benign neoplasms. Still other novel tumor types such as clear cell papillary renal cell carcinoma have been more recently recognized, which similarly have shown a conspicuous absence of aggressive behavior to date, suggesting that these too may be recategorized as noncancerous or may be premalignant neoplasms. This importance for prognosis is increasingly significant in the modern era, in which renal masses are increasingly found incidentally by imaging techniques at a small tumor size, raising consideration for less aggressive management options guided by renal mass biopsy diagnosis, including imaging surveillance, tumor ablation, or partial nephrectomy.

    Hyporeninemic hypoaldosteronism is an important underlying condition, causing hyperkalemia with hyperchloremic metabolic acidosis, disproportionate to the degree of renal insufficiency present. The principal defect in this syndrome is a reduced level of plasma renin activity, which results in secondary hypoaldosteronism. Diabetes mellitus is usually the primary underlying renal disease, though other causes of renal diseases associated with this syndrome have been described. This case report describes for the first time an elderly patient with multiple myeloma, in remission for more than 11 years, associated with the syndrome of hyporeninemic hypoaldosteronism at the time of diagnosis. The complete resolution of the syndrome after vigorous chemotherapy is an intriguing possibility.

    Epidemiological evidence of a relationship between vitamin D and kidney cancer risk has been inconsistent despite experimental data indicating that vitamin D and its metabolites may inhibit carcinogenesis. Previously we reported an inverse association between renal cell carcinoma (RCC) risk and occupational ultraviolet (UV) exposure among European men. In this study, we examined the association between occupational UV exposure and RCC risk among US residents and investigated whether this association varied by race and sex. Lifetime occupational data for 1,217 RCC cases and 1,235 controls in a population-based case-control study, conducted from 2002 to 2007, were assessed for occupational UV exposure. We evaluated exposure metrics in quartiles based on control exposure levels and calculated associations between RCC risk and occupational UV exposure using unconditional logistic regression adjusted for sex, race, body mass index, smoking, hypertension, center, education, family history of cancer and dietary vitamin D intake. A general pattern of decreasing RCC risk with increasing UV exposure was observed. Cases had significantly lower cumulative occupational UV exposure than controls (fourth quartile vs. first: odds ratio = 0.74 [95% confidence interval = 0.56-0.99], p-trend = 0.03). Similar results were observed for other UV exposure metrics. The association with occupational UV exposure was stronger for women than for men, but did not differ by race. Our findings suggest an inverse association between occupational UV exposure and RCC, particularly among women. Given the sex finding discrepancies in this study versus our previous study, additional research is need to clarify whether the protective effects of occupational UV exposure and RCC risk are real. © 2015 UICC.

    Renal cell cancer (RCC) is characterized by histological and molecular heterogeneity that may account for variable response to targeted therapies. We evaluated retrospectively with a next generation sequencing (NGS) approach using a pre-designed cancer panel the mutation burden of 32 lesions from 22 metastatic RCC patients treated with at least one tyrosine kinase or mTOR inhibitor. We identified mutations in the VHL, PTEN, JAK3, MET, ERBB4, APC, CDKN2A, FGFR3, EGFR, RB1, TP53 genes. Somatic alterations were correlated with response to therapy. Most mutations hit VHL1 (31,8%) followed by PTEN (13,6%), JAK3, FGFR and TP53 (9% each). Eight (36%) patients were wild-type at least for the genes included in the panel. A genotype concordance between primary RCC and its secondary lesion was found in 3/6 cases. Patients were treated with Sorafenib, Sunitinib and Temsirolimus with partial responses in 4 (18,2%) and disease stabilization in 7 (31,8%). Among the 4 partial responders, 1 (25%) was wild-type and 3 (75%) harbored different VHL1 variants. Among the 7 patients with disease stabilization 2 (29%) were wild-type, 2 (29%) PTEN mutated, and single patients (14% each) displayed mutations in VHL1, JAK3 and APC/CDKN2A. Among the 11 non-responders 7 (64%) were wild-type, 2 (18%) were p53 mutated and 2 (18%) VHL1 mutated. No significant associations were found among RCC histotype, mutation variants and response to therapies. In the absence of predictive biomarkers for metastatic RCC treatment, a NGS approach may address single patients to basket clinical trials according to actionable molecular specific alterations.

    In May and September, 2002, 14 private residential drinking water wells, one dewatering well at a lignite mine, eight surface water sites, and lignite from an active coal mine were sampled in five Parishes of northwestern Louisiana, USA. Using a geographic information system (GIS), wells were selected that were likely to draw water that had been in contact with lignite; control wells were located in areas devoid of lignite deposits. Well water samples were analyzed for pH, conductivity, organic compounds, and nutrient and anion concentrations. All samples were further tested for presence of fungi (cultures maintained for up to 28 days and colonies counted and identified microscopically) and for metal and trace element concentration by inductively-coupled plasma mass spectrometry and atomic emission spectrometry. Surface water samples were tested for dissolved oxygen and presence of pathogenic leptospiral bacteria. The Spearman correlation method was used to assess the association between the endpoints for these field/laboratory analyses and incidence of cancer of the renal pelvis (RPC) based on data obtained from the Louisiana Tumor Registry for the five Parishes included in the study. Significant associations were revealed between the cancer rate and the presence in drinking water of organic compounds, the fungi Zygomycetes, the nutrients PO4 and NH3, and 13 chemical elements. Presence of human pathogenic leptospires was detected in four out of eight (50%) of the surface water sites sampled. The present study of a stable rural population examined possible linkages between aquifers containing chemically reactive lignite deposits, hydrologic conditions favorable to the leaching and transport of toxic organic compounds from the lignite into the groundwater, possible microbial contamination, and RPC risk. ??

  18. Pro-Tumorigenic Phosphorylation of p120 Catenin in Renal and Breast Cancer.

    Antonis Kourtidis

    Full Text Available Altered protein expression and phosphorylation are common events during malignant transformation. These perturbations have been widely explored in the context of E-cadherin cell-cell adhesion complexes, which are central in the maintenance of the normal epithelial phenotype. A major component of these complexes is p120 catenin (p120, which binds and stabilizes E-cadherin to promote its adhesive and tumor suppressing function. However, p120 is also an essential mediator of pro-tumorigenic signals driven by oncogenes, such as Src, and can be phosphorylated at multiple sites. Although alterations in p120 expression have been extensively studied by immunohistochemistry (IHC in the context of tumor progression, little is known about the status and role of p120 phosphorylation in cancer. Here we show that tyrosine and threonine phosphorylation of p120 in two sites, Y228 and T916, is elevated in renal and breast tumor tissue samples. We also show that tyrosine phosphorylation of p120 at its N-terminus, including at the Y228 site is required for its pro-tumorigenic potential. In contrast, phosphorylation of p120 at T916 does not affect this p120 function. However, phosphorylation of p120 at T916 interferes with epitope recognition of the most commonly used p120 antibody, namely pp120. As a result, this antibody selectively underrepresents p120 levels in tumor tissues, where p120 is phosphorylated. Overall, our data support a role of p120 phosphorylation as a marker and mediator of tumor transformation. Importantly, they also argue that the level and localization of p120 in human cancer tissues immunostained with pp120 needs to be re-evaluated.

    Full Text Available Metastatic calcification has been associated with multiple-myeloma-induced hypercalcemia. Despite of a relatively high prevalence of metastatic pulmonary calcification in patients with multiple myeloma, only a few cases have been clinically and radiologically detected. A 45-year-old Hispanic male presented to the Emergency Department with complaint of worsening weakness and myalgia. Laboratory findings revealed renal insufficiency and hypercalcemia. CT scan of chest revealed calcified pleural and pulmonary nodule. Technetium (Tc 99 bone scan revealed diffuse activity in the pulmonary parenchyma consistent with metastatic pulmonary calcification. Metastatic pulmonary calcification, despite its high prevalence, remains undetected. This is, in part, due to its radiographic characteristic properties that evade detection by routine imaging studies. We present a case of a metastatic pulmonary calcification in a patient diagnosed with multiple myeloma and chronic kidney disease, as well as a brief literature review including clinical findings and treatment options.

    Background Metformin is a widely used biguanide drug for the treatment of type 2 diabetes. It has been revaluated as a potential anti-cancer drug with promising activity in various tumors. However, the precise mechanisms underlying the suppression of cancer cells by metformin remain not well understood. Material/Methods In this study, human renal cell carcinoma cell line ACHN was used to investigate the anti-proliferation effect of metformin. A cell counting kit-8 assay was used to detect the cell viability. The cell cycle distribution and apoptosis were analyzed by flow cytometry. The expression of cyclin D1 and p27KIP1 was detected by Western blot. The underlying mechanism involving miRNA34a was further investigated by quantitative RT-PCR and transfection with miRNA inhibitor specific for miRNA34a in ACHN, 769-P, and A498 cells. Results Metformin could significantly inhibit the proliferation of ACHN cells in a dose- and time-dependent manner. In addition, the results showed that metformin induced G0/G1 phase arrest and delayed entry into S phase in ACHN cells. It was shown that metformin downregulates the expression of cyclin D1 and increases the p27KIP1 level. Furthermore, metformin increased ACHN cell death. Lastly, miRNA34a was found to be upregulated by metformin in ACHN, 769-P, and A498 cells. Subsequently, it was demonstrated that inhibition of miRNA34a could partially attenuate the suppressive effect of metformin on renal cancer cell proliferation. Conclusions The study data revealed that metformin induced cell growth inhibition and cell cycle arrest partially by upregulating miRNA34a in renal cancer cells. PMID:28045889

    In this prospective study we determined the incidence of intact/fragmented immunoglobulin and Bence Jones protein in urine immunofixation using Sebia reagents and HydrasysTM 2 apparatus and compared the results to concentrations of serum free light chains (FLC) assessed using Siemens BNTM II nephelometer and the immunoassay Freelite (Binding Site) in 289 patients with multiple myeloma at diagnosis. It was found that in one third of IgG, IgA and IgD myeloma patients, intact/fragmented immunoglobulin can be detected in urine and is connected with impaired renal function and reduced survival. Urine immunofixation detects monoclonal protein (FLC and intact/fragmented immunoglobulin) in 66-79% of IgG and IgA myeloma patients while serum FLC immunoassay detect it in 82-94% of IgG and IgA myeloma patients. However, the latter method is inadequate for detection of intact/fragmented immunoglobulin in urine. Serum FLC immunoassay and urine immunofixation are complementary methods in diagnosing and monitoring monoclonal protein in patients with myeloma.

    B-cell maturation antigen is expressed on plasma cells. In this study, we have identified serum B-cell maturation antigen as a novel biomarker that can monitor and predict outcomes for multiple myeloma patients. Compared to healthy donors, patients with multiple myeloma showed elevated serum B-cell maturation antigen levels (Pmultiple myeloma patients (n=243). Specifically, patients with serum B-cell maturation antigen levels above the median level at the time of starting front-line (P=0.0043) or a new salvage therapy (P=0.0044) were found to have shorter progression-free survival. Importantly, serum B-cell maturation antigen levels did not show any dependence on renal function and maintained independent significance when tested against other known prognostic markers for multiple myeloma such as age, serum β2 microglobulin, hemoglobin, and bone disease. These data identify serum B-cell maturation antigen as a new biomarker to manage multiple myeloma patients. Copyright© Ferrata Storti Foundation.

    Melatonin (N-acetyl-5-methoxytryptamine) has recently gained attention as an anticancer agent and for combined cancer therapy. In this study, we investigated the underlying molecular mechanisms of the effects of melatonin on cancer cell death. Treatment with melatonin induced apoptosis and upregulated the expression of the pro-apoptotic protein Bcl-2-interacting mediator of cell death (Bim) in renal cancer Caki cells. Furthermore, downregulation of Bim expression by siRNA markedly reduced melatonin-mediated apoptosis. Melatonin increased Bim mRNA expression through the induction of Sp1 and E2F1 expression and transcriptional activity. We found that melatonin also modulated Bim protein stability through the inhibition of proteasome activity. However, melatonin-induced Bim upregulation was independent of melatonin's antioxidant properties and the melatonin receptor. Taken together, our results suggest that melatonin induces apoptosis through the upregulation of Bim expression at the transcriptional level and at the post-translational level.

    Full Text Available PURPOSE: The increasing incidence of small renal tumors in an aging population with comorbidities has stimulated the development of minimally invasive treatments. This study aimed to assess the efficacy and demonstrate feasibility of multimodality imaging of intratumoral administration of holmium-166 microspheres ((166HoAcAcMS. This new technique locally ablates renal tumors through high-energy beta particles, while the gamma rays allow for nuclear imaging and the paramagnetism of holmium allows for MRI. METHODS: (166HoAcAcMS were administered intratumorally in orthotopic renal tumors (Balb/C mice. Post administration CT, SPECT and MRI was performed. At several time points (2 h, 1, 2, 3, 7 and 14 days after MS administration, tumors were measured and histologically analyzed. Holmium accumulation in organs was measured using inductively coupled plasma mass spectrometry. RESULTS: (166HoAcAcMS were successfully administered to tumor bearing mice. A striking near-complete tumor-control was observed in (166HoAcAcMS treated mice (0.10±0.01 cm(3 vs. 4.15±0.3 cm(3 for control tumors. Focal necrosis and inflammation was present from 24 h following treatment. Renal parenchyma outside the radiated region showed no histological alterations. Post administration CT, MRI and SPECT imaging revealed clear deposits of (166HoAcAcMS in the kidney. CONCLUSIONS: Intratumorally administered (166HoAcAcMS has great potential as a new local treatment of renal tumors for surgically unfit patients. In addition to strong cancer control, it provides powerful multimodality imaging opportunities.

    Multiple myeloma (MM) is an incurable cancer characterized by clonal expansion of malignant plasma cells in the bone marrow and their egress into peripheral blood. The mechanisms of myeloma cells migration/invasion have remained unclear. Herein, we found SH3GL3 was highly expressed in the CD138-negative (CD138-) myeloma cells. The migration/invasion capability of CD138- cells was significantly higher than that in the CD138-positive (CD138+) cells. Silencing SH3GL3 using shRNA reduced myeloma cells migration/invasion. Conversely, overexpression of SH3GL3 increased myeloma cells migration/invasion. Moreover, SH3GL3 is also associated with the stemness and chemo-resistance of CD138- myeloma cells. Elevated expression of stem cell and multi-drug resistant markers were seen in the myeloma cells with overexpressed SH3GL3; while knocking-down SH3GL3 reduced the expression of these markers. A marked increase in p-PI3K and p-FAK was observed in the cells with overexpressed SH3GL3. To test if FAK/PI3K signaling pathway was involved in the SH3GL3-mediated myeloma cells migration, the cells transfected w/wo SH3GL3 cDNA were treated with FAK inhibitor 14 and PI3K inhibitor LY294002. Inhibition of FAK and PI3K attenuated SH3GL3-mediated migration /invasion. Our findings indicate that SH3GL3 plays an important role in myeloma cell migration/invasion, stemness and chemo-resistance. The SH3GL3-mediated myeloma cell migration/invasion is mediated by FAK/PI3K signaling pathway.

    Capon is a ligand protein of nitric oxide synthase 1. Recently, studies have shown that Capon is involved in the development of tumors. It is independent of the regulation of nitric oxide synthase 1 in this process. At the same time, studies have found that nitric oxide synthase 1 is expressed in multiple myeloma, but its role in the development and progression of myeloma remains unclear. In this study, we found that there was a different expression of Capon between the normal multiple myeloma cells and the adherent multiple myeloma cells. In the process of myeloma cell proliferation, the reduced expression of Capon reduces the arrest of the cell cycle in the G1 phase and promotes the proliferation of myeloma cells. Cell adhesion-mediated drug resistance is one of the most important factors, which affect the chemotherapy effect of multiple myeloma. If the expression of Capon is decreased, myeloma cells are adhered to fibronectin or bone marrow stromal cells (bone marrow mesenchymal stem cells). In addition, the sensitivity of the cell line to chemotherapeutic agents was reduced after silencing Capon in the myeloma cell line which was adhered to bone marrow mesenchymal stem cells. We also found that reduced expression of Capon resulted in the activation of the AKT signaling pathway. In conclusion, these results may be helpful in studying the role of Capon in multiple myeloma.

    The authors report the results of a prospective, multi-centre trial involving 87 patients with previously untreated myeloma who were treated by combination chemotherapy consisting of melphalan, cyclophosphamide, CCNU, prednisone and vincristine. 83.1% of patients had a high tumour mass (stage III on Durie and Salmon's classification). The response to treatment could be evaluated in 76 patients and 70% were found to respond. The median actuarial survival of the whole population is 30 months. The survival is significantly longer (p less than 0.001) in responders (median 40 months) than in non-responders (median: 17 months); the survival is significantly shorter (p less than 0.01) in subjects with renal failure (median: 10 months) than in subjects without renal failure (median: 36 months). This treatment is sufficiently well tolerated to be administered on an outpatient basis. One case of acute monoblastic leukaemia was observed. These results are similar to those reported in the literature.

    A review was made of 237 cases of multiple myeloma seen at the Institute of Radiology and Hematology of the Ferrara University from 1984 through 1990. The results showed skeletal involvement of the mandible to be present in 25 patients (10.54%). The diagnosis of multiple myeloma was based on the following criteria: 1) increased number of abnormal, atypical or immature plasma cells in the bone marrow; 2) the presence of a monoclonal protein in the serum or urine; 3) bone lesions consistent with those of myeloma. Symptoms include pain and swelling of the oral cavity, tooth mobility and loss, numbness along the inferior dental nerve, and paresthesia of the lower lip. The typical radiographic appearance is a well-defined "punched-out" lytic defect, solitary or multiple; sometimes, the defect enlarges and appears "bubbly" or septated. Permeative lytic areas, with blurred outlines, are a rare pattern, which is radiologically indistinguishable from skeletal metastases. The involvement of the oral cavity and jaw in multiple myeloma has been often reported in literature: nevertheless, if radiographs of the jaws had been systematically taken in all the cases, its incidence would probably have been much higher than previously suspected.

    Papillary renal-cell carcinoma, which accounts for 15%-20% of renal-cell carcinomas, is a heterogeneous disease that consists of various types of renal cancer, including tumors with indolent, multifocal presentation, and solitary tumors with an aggressive, highly lethal phenotype. Little is known about the genetic basis of sporadic papillary renal-cell carcinoma, and no effective forms of therapy for advanced disease exist. We performed comprehensive molecular characterization of 161 primary papillary renal-cell carcinomas, using whole-exome sequencing, copy-number analysis, messenger RNA and microRNA sequencing, DNA-methylation analysis, and proteomic analysis. Types 1 and 2 papillary renal-cell carcinomas were shown to be different types of renal cancer characterized by specific genetic alterations, with type 2 further classified into 3 individual subgroups on the basis of molecular differences associated with patient survival. Type 1 tumors were associated with MET alterations, whereas type 2 tumors were characterized by CDKN2A silencing, SETD2 mutations, TFE3 fusions, and increased expression of the NRF2-antioxidant response element (ARE) pathway. A CpG island methylator phenotype was observed in a distinct subgroup of type 2 papillary renal-cell carcinomas that was characterized by poor survival and mutation of the gene encoding fumarate hydratase. Types 1 and 2 papillary renal-cell carcinomas were shown to be clinically and biologically distinct. Alterations in the MET pathway were associated with type 1, and activation of the NRF2-ARE pathway was associated with type 2; CDKN2A loss and CpG island methylator phenotype in type 2 conveyed a poor prognosis. Furthermore, type 2 papillary renal-cell carcinoma consisted of at least 3 subtypes based on molecular and phenotypic features. (Funded by the National Institutes of Health.).

    Although myeloma light chains are known to undergo receptor-mediated endocytosis in the kidney, the molecular identity of the receptor has not been characterized. We examined the interaction between cubilin (gp280) and four species of light chains isolated from the urine of patients with multiple myeloma. Four lines of evidence identify cubilin, a giant glycoprotein receptor, which is restricted in distribution to endocytic scavenger pathways and which has potent effects on endosomal trafficking, as a potentially physiologically relevant binding site for light chains: 1) light chains coeluted during immunoaffinity purification of cubilin; 2) polyclonal antisera to cubilin but not control sera, displaced human light chain binding from rat renal brush-border membranes; 3) cubilin bound to multiple species of light chains during surface plasmon resonance; 4) anti-cubilin antiserum interfered with light chain endocytosis by visceral yolk sac epithelial cells. However, both binding of light chains to brush-border membranes and endocytosis of light chains by yolk sac epithelial cells were only partially inhibited by anticubilin antibodies, suggesting presence of additional or alternate binding sites for light chains. Excess light chain had a potent inhibitory effect on endosomal fusion in vitro. Binding showed dose and time-dependent saturability with low-affinity, high-capacity equilibrium binding parameters. These data demonstrate that cubilin plays a role in the endocytosis and trafficking of light chains in renal proximal tubule cells.

    BACKGROUND The American Joint Committee on Cancer’s (AJCC) 7th edition cancer staging manual reflects recent changes in cancer care practices. This report assesses changes from the AJCC 6th to the AJCC 7th edition stage distributions and the quality of site-specific factors (SSFs). METHODS Incidence data for renal parenchyma and pelvis and ureter cancers from 18 Surveillance, Epidemiology, and End Results (SEER) registries were examined, including staging trends during 2004–2010, stage distribution changes between the AJCC 6th and 7th editions, and SSF completeness for cases diagnosed in 2010. RESULTS From 2004 to 2010, the percentage of stage I renal parenchyma cancers increased from 50% to 58%, whereas stage IV and unknown stage cases decreased (18% to 15%, and 10% to 6%, respectively). During this period, the percentage of stage 0a renal pelvis and ureter cancers increased from 21% to 25%, and stage IV and unknown stage tumors decreased (20% to 18%, and 7% to 5%, respectively). Stage distributions under the AJCC 6th and 7th editions were about the same. For renal parenchymal cancers, 71%–90% of cases had known values for 6 required SSFs. For renal pelvis and ureter cancers, 74% of cases were coded as known for SSF1 (WHO/ISUP grade) and 47% as known for SSF2 (depth of renal parenchymal invasion). SSF values were known for larger proportions of cases with reported resections. CONCLUSIONS Stage distributions between the AJCC 6th and 7th editions were similar. SSFs were known for more than two-thirds of cases, providing more detail in the SEER database relevant to prognosis. PMID:25412394

    Increasing evidence revealed that miRNAs, the vital regulators of gene expression, are involved in various cellular processes, including cell growth, differentiation, apoptosis and progression. In addition, miRNAs act as oncogenes and/or tumor suppressors. The present study aimed to verify the potential roles of miR148b in human renal cancer cells. miR‑148b was found to be downregulated in human renal cancel tissues and human renal cancer cell lines. Functional studies demonstrated that plasmid‑mediated overexpression of miR‑148b promoted cell proliferation, increased the S‑phase population of the cell cycle and enhanced apoptosis in the 786‑O and OS‑RC‑2 renal cancer cell lines, while it did not appear to affect the total number of viable cells according to a Cell Counting Kit‑8 assay. Subsequently, a luciferase reporter assay verified that miR148b directly targeted mitogen‑activated protein kinase (MAPK) kinase kinase 9 (MAP3K9), an upstream activator of MAPK kinase/c‑Jun N‑terminal kinase (JNK) signaling, suppressing the protein but not the mRNA levels. Furthermore, western blot analysis indicated that overexpression of miR148b in renal cancer cells inhibited MAPK/JNK signaling by decreasing the expression of phosphorylated (p)JNK. In addition, overexpression of MAP3K9 and pJNK was detected in clinical renal cell carcinoma specimens compared with that in their normal adjacent tissues. The present study therefore suggested that miR‑148b exerts an oncogenic function by enhancing the proliferation and apoptosis of renal cancer cells by inhibiting the MAPK/JNK pathway.

    Recent studies suggest that circulating tumor cells and cell-free DNA may represent powerful non-invasive tools for monitoring disease in patients with solid and hematologic malignancies. Here, we conducted a pilot study in 27 myeloma patients to explore the clonotypic V(D)J rearrangement for monitoring circulating myeloma cells and cell-free myeloma DNA. Next-generation sequencing was used to define the myeloma V(D)J rearrangement and for subsequent peripheral blood tracking after treatment initiation. Positivity for circulating myeloma cells/cell-free myeloma was associated with conventional remission status (P<0.001) and 91% of non-responders/progressors versus 41% of responders had evidence of persistent circulating myeloma cells/cell-free myeloma DNA (P<0.001). About half of the partial responders showed complete clearance of circulating myeloma cells/cell-free myeloma DNA despite persistent M-protein, suggesting that these markers are less inert than the M-protein, rely more on cell turnover and, therefore, decline more rapidly after initiation of effective treatment. Positivity for circulating myeloma cells and for cell-free myeloma DNA were associated with each other (P=0.042), but discordant in 30% of cases. This indicates that cell-free myeloma DNA may not be generated entirely by circulating myeloma cells and may reflect overall tumor burden. Prospective studies need to define the predictive potential of high-sensitivity determination of circulating myeloma cells and DNA in the monitoring of multiple myeloma. PMID:28183851

    Full Text Available Cast nephropathy is the most frequent pattern of renal involvement in multiple myeloma characterized by presence of tubular casts with characteristic morphology that are composed of monotypic (either kappa or lambda light chains as seen by immunofluorescence microscopy. Rarely these casts may show evidence of amyloidogenesis and assume a unique morphology, which needs to be appreciated for arriving at accurate diagnosis. We present the case of an elderly male presenting with features of acute kidney injury and detected with extensive inspissation of intratubular casts with lambda light chain restriction and a unique morphology with spiculated congophilic periphery. Further investigations confirmed the presence of systemic myeloma. Presence of intratubular amyloid casts is a rare occurrence which needs to be recognized by the pathologist and forms a vital element in timely diagnosis of the systemic disease which often presents with renal involvement.

    Dicer and Drosha are key enzymes in the miRNA-processing pathway which is altered in many human cancers. We analyzed Dicer and Drosha expression levels by quantitative PCR in 151 patients with monoclonal gammopathies: 102 symptomatic myeloma patients, 23 smoldering myelomas and 26 monoclonal gammopathy of undetermined significance. We found that Dicer expression values were significantly higher in monoclonal gammopathy of undetermined significance than in smoldering myelomas and symptomatic myeloma (mean ± SD, 0.84 ± 0.36 vs. 0.60 ± 0.23 and 0.62 ± 0.51; P<0.01). Moreover, the median progression-free survival was significantly longer in symptomatic myeloma patients with high expression of Dicer (not reached vs. 23.6 months; P=0.02). By contrast, no differences in the expression of Drosha among these groups of patients were observed. Our data suggest that Dicer expression may play an important role in the progression and prognosis of monoclonal gammopathies.

    2015-01-01

    Full Text Available Metastatic renal cell cancer is associated with poor prognosis and survival and is resistant to conventional chemotherapy. Therapeutic targeting of molecular pathways for tumor angiogenesis and other specific activation mechanisms offers improved tumor response and prolonged survival. A 48-year-old, female patient presented with large right renal mass with features suggesting of renal cell cancer without metastasis on contrast enhanced computed tomography (CT. Right radical nephrectomy was done. After 9 months of surgery, she got metastasis in lung, liver and ovary. The patient received sunitinib via an expanded access program. After eight 6-week cycles of sunitinib, a reassessment CT scan confirmed an excellent partial response with the almost complete disappearance (90% of liver and lung metastasis but the adnexal mass had increased in size (>10 times and the possibility was thought of second malignancy. Excision of the mass performed. Histopathology of the mass depicted metastatic renal cell cancer. There is possibility of a ′site-specific anti-angiogenic potentiation mechanism′ of malignancy in relation to sunitinib based upon the preclinical studies, in reference to the index case. Regression of one site with concurrent progression is possible. The exact mechanism of site-specific response, especially organ specific progression by vascular endothelial growth factor inhibitors in metastatic renal cell cancer warrants further study.

    Diagnostic procedures performed on patients with multiple myeloma typically reveal lytic bone lesions, osteopenia or osteoporosis, bone marrow infiltration by plasma cells as well as overproduction of immunoglobulin or light chains in the serum or urine. Skeletal manifestations are extremely variable and the unusual forms have been described extensively. Extramedullary plasma-cell tumours (plasmocytoma) are found in about 5% of newly diagnosed patients with multiple myelomas. In this paper we present eight patients with atypical forms of multiple myeloma.

    There is increasing evidence that some cancer therapies can promote tumor immunogenicity to boost the endogenous antitumor immune response. In this study, we used the novel combination of agonistic anti-TRAIL-R1 antibody (mapatumumab, Mapa) with low dose bortezomib (LDB) for this purpose. The combination induced profound myeloma cell apoptosis, greatly enhanced the uptake of myeloma cell apoptotic bodies by dendritic cell (DC) and induced anti-myeloma cytotoxicity by both CD8(+) T cells and NK cells. Cytotoxic lymphocyte expansion was detected within 24 h of commencing therapy and was maximized when myeloma-pulsed DC were co-treated with low dose bortezomib and mapatumumab (LDB+Mapa) in the presence of NK cells. This study shows that Mapa has two distinct but connected modes of action against multiple myeloma (MM). First, when combined with LDB, Mapa produced powerful myeloma cell apoptosis; secondly, it promoted DC priming and an NK cell-mediated expansion of anti-myeloma cytotoxic lymphocyte (CTL). Overall, this study indicates that Mapa can be used to drive potent anti-MM immune responses.

    Autologous stem cell transplantation (ASCT) and novel therapies have improved overall survival of patients with multiple myeloma; however, most patients relapse and eventually succumb to their disease. Evidence indicates that residual cancer cells contaminate autologous grafts and may contribute to early relapses after ASCT. Here, we demonstrate that ex vivo treatment with an oncolytic poxvirus called myxoma virus results in specific elimination of human myeloma cells by inducing rapid cellular apoptosis while fully sparing normal hematopoietic stem and progenitor cells (HSPCs). The specificity of this elimination is based on strong binding of the virus to myeloma cells coupled with an inability of the virus to bind or infect CD34+ HSPCs. These two features allow myxoma to readily identify and distinguish even low levels of myeloma cells in complex mixtures. This ex vivo MYXV treatment also effectively inhibits systemic in vivo engraftment of human myeloma cells into immunodeficient mice and results in efficient elimination of primary CD138+ myeloma cells contaminating patient hematopoietic cell products. We conclude that ex vivo myxoma treatment represents a safe and effective method to selectively eliminate myeloma cells from hematopoietic autografts prior to reinfusion. PMID:22516053

    Background: Increased expression of the tetraspanin TSPAN7 has been observed in a number of cancers; however, it is unclear how TSPAN7 plays a role in cancer progression. Methods: We investigated the expression of TSPAN7 in the haematological malignancy multiple myleoma (MM) and assessed the consequences of TSPAN7 expression in the adhesion, migration and growth of MM plasma cells (PC) in vitro and in bone marrow (BM) homing and tumour growth in vivo. Finally, we characterised the association of TSPAN7 with cell surface partner molecules in vitro. Results: TSPAN7 was found to be highly expressed at the RNA and protein level in CD138{sup +} MM PC from approximately 50% of MM patients. TSPAN7 overexpression in the murine myeloma cell line 5TGM1 significantly reduced tumour burden in 5TGM1/KaLwRij mice 4 weeks after intravenous adminstration of 5TGM1 cells. While TSPAN7 overexpression did not affect cell proliferation in vitro, TSPAN7 increased 5TGM1 cell adhesion to BM stromal cells and transendothelial migration. In addition, TSPAN7 was found to associate with the molecular chaperone calnexin on the cell surface. Conclusion: These results suggest that elevated TSPAN7 may be associated with better outcomes for up to 50% of MM patients. - Highlights: • TSPAN7 expression is upregulated in newly-diagnosed patients with active multiple myeloma. • Overexpression of TSPAN7 inhibits myeloma tumour development in vivo. • TSPAN7 interacts with calnexin at the plasma membrane in a myeloma cell line.

    Clear cell renal cell carcinoma is by far the most common form of kidney cancer; however, a number of histologically similar tumors are now recognized and considered distinct entities. The Cancer Genome Atlas published data set was queried (http://cbioportal.org) for clear cell renal cell carcinoma tumors lacking VHL gene mutation and chromosome 3p loss, for which whole-slide images were reviewed. Of the 418 tumors in the published Cancer Genome Atlas clear cell renal cell carcinoma database, 387 had VHL mutation, copy number loss for chromosome 3p, or both (93%). Of the remaining, 27/31 had whole-slide images for review. One had 3p loss based on karyotype but not sequencing, and three demonstrated VHL promoter hypermethylation. Nine could be reclassified as distinct or emerging entities: translocation renal cell carcinoma (n=3), TCEB1 mutant renal cell carcinoma (n=3), papillary renal cell carcinoma (n=2), and clear cell papillary renal cell carcinoma (n=1). Of the remaining, 6 had other clear cell renal cell carcinoma-associated gene alterations (PBRM1, SMARCA4, BAP1, SETD2), leaving 11 specimens, including 2 high-grade or sarcomatoid renal cell carcinomas and 2 with prominent fibromuscular stroma (not TCEB1 mutant). One of the remaining tumors exhibited gain of chromosome 7 but lacked histological features of papillary renal cell carcinoma. Two tumors previously reported to harbor TFE3 gene fusions also exhibited VHL mutation, chromosome 3p loss, and morphology indistinguishable from clear cell renal cell carcinoma, the significance of which is uncertain. In summary, almost all clear cell renal cell carcinomas harbor VHL mutation, 3p copy number loss, or both. Of tumors with clear cell histology that lack these alterations, a subset can now be reclassified as other entities. Further study will determine whether additional entities exist, based on distinct genetic pathways that may have implications for treatment.Modern Pathology advance online publication, 21

    Multiple myeloma remains incurable with conventional treatments. However, new active drugs, including the immunomodulatory agents, thalidomide and lenalidomide,and the proteasome inhibitors bortezomib and NPI-0052, and other targeted therapies, have shown promising anti-myeloma activity. These agents represent a new generation of treatments for multiple myeloma that affect both specific intracellular signaling pathways and the tumor microenvironment. This review therefore focuses on the extensive clinical data available from studies of these drugs in the treatment of newly diagnosed, refractory and relapsed multiple myeloma.

    Despite improved outcomes in newly diagnosed multiple myeloma, virtually all patients relapse and ultimately develop drug-resistant disease. Aberrant RAS/MAPK signaling is activated in the majority of relapsed/refractory multiple myeloma patients, but its biological consequences are not fully understood. Self-renewal, as defined by the long-term maintenance of clonogenic growth, is essential for disease relapse, and we examined the role of RAS/MAPK activation on multiple myeloma self-renewal by targeting IQ motif-containing GTPase-activating protein 1 (IQGAP1), an intracellular scaffold protein required for mutant RAS signaling. We found that loss of IQGAP1 expression decreased MAPK signaling, cell-cycle progression, and tumor colony formation. Similarly, a peptide mimicking the WW domain of IQGAP1 that interacts with ERK inhibited the clonogenic growth and self-renewal of multiple myeloma cell lines and primary clinical specimens in vitro as well as tumor-initiating cell frequency in immunodeficient mice. During multiple myeloma progression, self-renewal may be enhanced by aberrant RAS/MAPK signaling and inhibited by targeting IQGAP1.

    Constitutive activation of the transcription factor STAT3 contributes to the pathogenesis of many cancers, including multiple myeloma (MM). Since STAT3 is dispensable in most normal tissue, targeted inhibition of STAT3 is an attractive therapy for patients with these cancers. To identify STAT3 inhibitors, we developed a transcriptionally based assay and screened a library of compounds known to be safe in humans. We found the drug nifuroxazide to be an effective inhibitor of STAT3 function. Nifuroxazide inhibits the constitutive phosphorylation of STAT3 in MM cells by reducing Jak kinase autophosphorylation, and leads to down-regulation of the STAT3 target gene Mcl-1. Nifuroxazide causes a decrease in viability of primary myeloma cells and myeloma cell lines containing STAT3 activation, but not normal peripheral blood mononuclear cells. Although bone marrow stromal cells provide survival signals to myeloma cells, nifuroxazide can overcome this survival advantage. Reflecting the interaction of STAT3 with other cellular pathways, nifuroxazide shows enhanced cytotoxicity when combined with either the histone deacetylase inhibitor depsipeptide or the MEK inhibitor UO126. Therefore, using a mechanistic-based screen, we identified the clinically relevant drug nifuroxazide as a potent inhibitor of STAT signaling that shows cytotoxicity against myeloma cells that depend on STAT3 for survival.

  20. Nonreciprocal chromosomal translocations in renal cancer involve multiple DSBs and NHEJ associated with breakpoint inversion but not necessarily with transcription.

    Chromosomal translocations and other abnormalities are central to the initiation of cancer in all cell types. Understanding the mechanism is therefore important to evaluate the evolution of cancer from the cancer initiating events to overt disease. Recent work has concentrated on model systems to develop an understanding of the molecular mechanisms of translocations but naturally occurring events are more ideal case studies since biological selection is absent from model systems. In solid tumours, nonreciprocal translocations are most commonly found, and accordingly we have investigated the recurrent nonreciprocal t(3;5) chromosomal translocations in renal carcinoma to better understand the mechanism of these naturally occurring translocations in cancer. Unexpectedly, the junctions of these translocations can be associated with site-specific, intrachromosomal inversion involving at least two double strand breaks (DSB) in cis and rejoining by nonhomologous end joining or micro-homology end joining. However, these translocations are not necessarily associated with transcribed regions questioning accessibility per se in controlling these events. In addition, intrachromosomal deletions also occur. We conclude these naturally occurring, nonreciprocal t(3;5) chromosomal translocations occur after complex and multiple unresolved intrachromosomal DSBs leading to aberrant joining with concurrent interstitial inversion and that clonal selection of cells is the critical element in cancer development emerging from a plethora of DSBs that may not always be pathogenic.

    Plasma cell myeloma is a clinically heterogeneous malignancy accounting for approximately one to 2% of newly diagnosed cases of cancer worldwide. Treatment options, in addition to long-established cytotoxic drugs, include autologous stem cell transplant, immune modulators, proteasome inhibitors and monoclonal antibodies, plus further targeted therapies currently in clinical trials. Whilst treatment decisions are mostly based on a patient’s age, fitness, including the presence of co-morbidities, and tumour burden, significant scope exists for better risk stratification, sub-classification of disease, and predictors of response to specific therapies. Clinical staging, recurring acquired cytogenetic aberrations, and serum biomarkers such as β-2 microglobulin, and free light chains are in widespread use but often fail to predict the disease progression or inform treatment decision making. Recent scientific advances have provided considerable insight into the biology of myeloma. For example, gene expression profiling is already making a contribution to enhanced understanding of the biology of the disease whilst Next Generation Sequencing has revealed great genomic complexity and heterogeneity. Pathways involved in the oncogenesis, proliferation of the tumour and its resistance to apoptosis are being unravelled. Furthermore, knowledge of the tumour cell surface and its interactions with bystander cells and the bone marrow stroma enhance this understanding and provide novel targets for cell and antibody-based therapies. This review will discuss the development in understanding of the biology of the tumour cell and its environment in the bone marrow, the implementation of new therapeutic options contributing to significantly improved outcomes, and the progression towards more personalised medicine in this disorder.

    Full Text Available Pazopanib is an oral angiogenesis inhibitor, currently approved for treatment of metastatic renal cell carcinoma (mRCC and soft tissue sarcoma. The present study analyzed the outcomes of pazopanib in first-line treatment of mRCC, in a single Italian cancer center. In the light of the retrospective, observational nature and the unselected population, our experience can be defined a real-world study. The medical records of 38 mRCC patients treated with front-line pazopanib were retrospectively reviewed and analyzed. The progression free survival (PFS and the overall survival (OS were the primary endpoints, while secondary objectives included Objective Response Rate (ORR, Disease Control Rate (DCR, and treatment tolerability. Pazopanib achieved a median PFS (mPFS of 12.7 months (95% CI, 6.9-18.5 months. The median OS (mOS was 26.2 months (95% CI, 12.6-39.9 months; the observed ORR and DCR were 30.3% and 72.7%, respectively, with a median duration of response of 11 weeks. mPFS appeared not to be influenced by number of co-morbidities (3, gender, Fuhrman grade and age. Conversely, the ORR and the DCR positively affect the mPFS (HR=0.05 [95% CI, 0.05-055], p=0.01; HR=0.10 [95% CI, 0.02-0.43], p=0.002 respectively. A worse outcome was associated with a lower mPFS in patients with liver metastases (p= 0.2 and with a high tumor burden (number of metastatic sites 6 (p= 0.08. Worst OS was observed in patients age >70 years old (HR=6.91 [95% CI, 1.49-31.91], p=0.01. The treatment was well tolerated: no grade 4 adverse events, nor discontinuation due to toxicities was reported. Grade 3 hypertension affected positively the OS reaching the statistical significance (HR=0.22 [95% CI, 0.05-0.8], p=0.03 and thyroid dysfunction (hypo and hyperthyroidism seems to correlate with better outcome in terms of a longer mPFS (HR=0.12 [95% CI, 0.02-0.78], p=0.02. Our results are consistent with those reported in prospective phase III trials and the published retrospective

    As rapidly developing patient-derived xenografts (PDX) could represent potential sources of cancer stem cells (CSC), we selected and characterized non-cultured PDX cell suspensions from four different renal carcinomas (RCC). Only the cell suspensions from the serial xenografts (PDX-1 and PDX-2) of an undifferentiated RCC (RCC-41) adapted to the selective CSC medium. The cell suspension derived from the original tumor specimen (RCC-41-P-0) did not adapt to the selective medium and strongly expressed CSC-like markers (CD133 and CD105) together with the non-CSC tumor marker E-cadherin. In comparison, PDX-1 and PDX-2 cells exhibited evolution in their phenotype since PDX-1 cells were CD133high/CD105-/Ecadlow and PDX-2 cells were CD133low/CD105-/Ecad-. Both PDX subsets expressed additional stem cell markers (CD146/CD29/OCT4/NANOG/Nestin) but still contained non-CSC tumor cells. Therefore, using different cell sorting strategies, we characterized 3 different putative CSC subsets (RCC-41-PDX-1/CD132+, RCC-41-PDX-2/CD133-/EpCAMlow and RCC-41-PDX-2/CD133+/EpCAMbright). In addition, transcriptomic analysis showed that RCC-41-PDX-2/CD133− over-expressed the pluripotency gene ERBB4, while RCC-41-PDX-2/CD133+ over-expressed several tumor suppressor genes. These three CSC subsets displayed ALDH activity, formed serial spheroids and developed serial tumors in SCID mice, although RCC-41-PDX-1/CD132+ and RCC-41-PDX-2/CD133+ displayed less efficiently the above CSC properties. RCC-41-PDX-1/CD132+ tumors showed vessels of human origin with CSC displaying peri-vascular distribution. By contrast, RCC-41-PDX-2 originated tumors exhibiting only vessels of mouse origin without CSC peri-vascular distribution. Altogether, our results indicate that PDX murine microenvironment promotes a continuous redesign of CSC phenotype, unmasking CSC subsets potentially present in a single RCC or generating ex novo different CSC-like subsets.

    There has been little information about metastatic behavior of renal cell carcinoma (RCC) cells because human cancers metastasize only rarely in immunodeficient mice. Moreover, it is difficult to know the effect of host immunity on RCC metastasis due to lack of such RCC cells as transplantable in not only xenograft models but also counterparts with intact immunity. Therefore, we scrutinized in vivo metastasis of RCC cells to seek for the optimal preclinical model to study metastatic behavior. The luciferase-expressing three representative human RCC cell lines (Caki-1, A498, and 786-O) and rat ACI-RCC cell which were established in our laboratory were transplanted into nonobese diabetic/severe combined immunodeficient (NOD/SCID) mice or immunocompetent ACI rats by intracardiac injection as well as orthotopic inoculation. Metastasis was monitored using a bioluminescent imaging technique. Metastasis was rare in the three human RCC cells even when they were directly disseminated into systemic circulation under the condition least susceptible to host immune attack in NOD/SCID mice. In contrast, ACI-RCC cells spontaneously metastasized to pulmonary tissue from orthotopic tumor sites and systemically spread via intracardiac route. Metastases were more extensive when the cells were inoculated into an immunodeficient host, implying suppressive effect of host immunity on colonization of RCC cells. These results suggest that the representative human RCC cells are not adequate resource to study metastasis but that the luciferase-labeled ACI-RCC cell characterized by its luminescent stability, enhanced tumorigenicity, and widespread metastatic potential provides a useful in vivo model for preclinical assessment of cancer progression and potential therapies against RCC.

    Discoidin domain receptor I (DDR1) is confirmed as a receptor tyrosine kinase (RTK), which plays a consequential role in a variety of cancers. Nevertheless, the influence of DDR1 expression and development in renal clear cell carcinoma (RCCC) are still not well corroborated. In our research, we firstly discovered that the expression level of DDR1 was remarkable related to TNM stage (p = 0.032), depth of tumor invasion (p = 0.047), and lymph node metastasis (p = 0.034) in 119 RCCC tissue samples using tissue microarray. The function of DDR1 was then evaluated in vitro using collagen I and DDR1 small interfering RNA (siRNA) to regulate the expression of DDR1 in OS-RC-2 and ACHN renal cancer cells (RCC). DDR1 expression correlated with increased RCC cell migration, invasion, and angiogenesis. Further study revealed that high expression of DDR1 can result in epithelial to mesenchymal transition (EMT) activation. Western blot assay showed that the N-cadherin protein and vimentin were induced while E-cadherin was reduced after DDR1 over expression. Our results suggest that DDR1 is both a prognostic marker for RCCC and a potential functional target for therapy.

    Multiple myeloma is a hematologic disorder characterized by the infiltration and proliferation of monoclonal plasma cells mainly in the bone marrow. The main symptoms are hypercalcemia, renal impairment, cytopenia/anemia and bone disease - summarized as CRAB-criteria. Symptomatic multiple myeloma is consistently preceded by asymptomatic premalignant stages called monoclonal gammopathy of undetermined significance and smoldering multiple myeloma. Staging of multiple myeloma is based on the measurement of the monoclonal protein in serum and urine as well as the assessment of impairment of hematopoiesis, renal function and mineralized bone. In the last decade the development of novel therapeutic agents has led to an increase in response rates and survival time of patients with multiple myeloma, which further stresses the value of response assessment by imaging. Cross sectional imaging like MRI and CT is currently replacing conventional radiological surveys in the initial work-up and follow-up of patients with monoclonal plasma cell diseases. The added value of MRI is to improve initial staging by unraveling a diffuse infiltration of bone marrow by plasma cells, a focal pattern or a combination of both. Furthermore, a complete remission of myeloma confirmed by MRI and CT goes along with a better prognosis compared to a complete response based only on serological parameters.

    Recent advancement in cancer research has shown that tumors are highly heterogeneous, and multiple phenotypically different cell populations are found in a single tumor. Cancer development and tumor growth are driven by specific types of cells-stem cell-like cancer cells (SCLCCs)-which are also responsible for metastatic spread and drug resistance. This research was designed to verify the presence of SCLCCs in renal cell cancer cell lines. Subsequently, we aimed to characterize phenotype and cell biology of CD105+ cells, defined previously as renal cell carcinoma tumor-initiating cells. The main goal of the project was to describe the gene-expression profile of stem cell-like cancer cells of primary tumor and metastatic origin. Real-time PCR analysis of stemness genes (Oct-4, Nanog and Ncam) and soft agar colony formation assay were conducted to check the stemness properties of renal cell carcinoma (RCC) cell lines. FACS analysis of CD105+ and CD133+ cells was performed on RCC cells. Isolated CD105+ cells were verified for expression of mesenchymal markers-CD24, CD146, CD90, CD73, CD44, CD11b, CD19, CD34, CD45, HLA-DR and alkaline phosphatase. Hanging drop assay was used to investigate CD105+ cell-cell cohesion. Analysis of free-floating 3D spheres formed by isolated CD105+ was verified, as spheres have been hypothesized to contain undifferentiated multipotent progenitor cells. Finally, CD105+ cells were sorted from primary (Caki-2) and metastatic (ACHN) renal cell cancer cell lines. Gene-expression profiling of sorted CD105+ cells was performed with Agilent's human GE 4x44K v2 microarrays. Differentially expressed genes were further categorized into canonical pathways. Network analysis and downstream analysis were performed with Ingenuity Pathway Analysis. Metastatic RCC cell lines (ACHN and Caki-1) demonstrated higher colony-forming ability in comparison to primary RCC cell lines. Metastatic RCC cell lines harbor numerous CD105+ cell subpopulations and have

    Full Text Available BACKGROUND: More than 200 clinical trials have been performed using dendritic cells (DC as cellular adjuvants in cancer. Yet the key question whether there is a link between immune and clinical response remains unanswered. Prostate and renal cell cancer (RCC have been extensively studied for DC-based immunotherapeutic interventions and were therefore chosen to address the above question by means of a systematic review and meta-analysis. METHODOLOGY/PRINCIPAL FINDINGS: Data was obtained after a systematic literature search from clinical trials that enrolled at least 6 patients. Individual patient data meta-analysis was performed by means of conditional logistic regression grouped by study. Twenty nine trials involving a total of 906 patients were identified in prostate cancer (17 and RCC (12. Objective response rates were 7.7% in prostate cancer and 12.7% in RCC. The combined percentages of objective responses and stable diseases (SD amounted to a clinical benefit rate (CBR of 54% in prostate cancer and 48% in RCC. Meta-analysis of individual patient data (n = 403 revealed the cellular immune response to have a significant influence on CBR, both in prostate cancer (OR 10.6, 95% CI 2.5-44.1 and in RCC (OR 8.4, 95% CI 1.3-53.0. Furthermore, DC dose was found to have a significant influence on CBR in both entities. Finally, for the larger cohort of prostate cancer patients, an influence of DC maturity and DC subtype (density enriched versus monocyte derived DC as well as access to draining lymph nodes on clinical outcome could be demonstrated. CONCLUSIONS/SIGNIFICANCE: As a 'proof of principle' a statistically significant effect of DC-mediated cellular immune response and of DC dose on CBR could be demonstrated. Further findings concerning vaccine composition, quality control, and the effect of DC maturation status are relevant for the immunological development of DC-based vaccines.

    ERG expression has been described as a frequent event in prostate cancer indicating poor prognosis and promoting oncogenesis. It has also been demonstrated in Ewing's sarcoma, acute myeloid leukemia and acute T-lymphoblastic leukemia but could not be found in other epithelial tumors, Hodgkin's or Non-Hodgkin's lymphoma. We aimed to analyze ERG expression in multiple myeloma, following an index case of a patient with metastases of unknown origin in the spine strongly expressing ERG, which were thought to be of prostatic origin but turned out to be plasmacytic lesions. We subsequently selected 12 formalin-fixed, paraffin-embedded tissue samples of multiple myeloma from our archives and performed immunohistochemical staining for ERG. All 12 analyzed cases showed strong nuclear expression of ERG in >90% of tumor cells (myeloma cells). This report highlights a potential and critical diagnostic pitfall in biopsy specimens where morphology is only of limited assistance in reaching the correct diagnosis. It urges pathologists to exercise caution in cases where strong ERG-positivity implicates the presence of a prostatic neoplasia and illustrates the need for further immunohistochemical examination.

    Von Hippel-Lindau (VHL) disease is an autosomal dominant inherited syndrome occurring in one out of 36,000 live births. Diagnosis could be a challenge in patients with no familial VHL history. Renal cancer (RCC) represents one of the most important manifestations. RCC is usually recurrent and multifocal. Actually treating RCC in VHL patients represent a clinical dilemma: the oncological outcomes must be balanced against renal function preservation. A young man with a negative familial history was referred to our department with seven misdiagnosed renal masses. VHL disease was determined through genetic test. The multiple RCCs were treated by surgery and percutaneous thermal ablation by radiofrequency ablation (RFA) with complete control of RCC and no impairment of renal function. This case history confirms that VHL disease has to be suspected in young patients with evidence of synchronous multiple renal masses and in presence of specific clinical criteria.RFA appears to be safe in terms of oncological radicalism and in renal function preservation.In hereditary RCC, we should purpose, whenever it is possible, minimally invasive treatment in terms of low hospital stay and a minimal loss of renal tissue.

    The consistent appearance of specific chromosomal translocations in multiple myeloma has suggested that the positioning of chromosomes in the interphase nucleus might play a role in the occurrence of particular chromosomal rearrangements associated with malignant transformation. Using fluorescence in situ hybridization, we have determined the positions of selected chromosome pairs (18 and 19, 9 and 22, 4 and 14, 14 and 16, 11 and 14) in interphase nuclei of myeloma cells compared to normal lymphocytes of treatment-naïve patients. All chromosome pairs were arranged in a nonrandom pattern. Chromosomes commonly involved in myeloma-associated translocations (4 and 14, 14 and 16, 11 and 14) were found in close spatial proximity, and this is correlated with the occurrence of overlapping chromosome territories. The spatial distribution of chromosomes may increase the possibility of chromosomal translocations in multiple myeloma. © 2016 The Authors International Journal of Cancer published by John Wiley & Sons Ltd on behalf of UICC.

    In the USA at the beginning of this century, the average overall survival in patients with multiple myeloma was about 3 years. Around that time, three drugs (bortezomib, lenalidomide and thalidomide) were introduced for the treatment of multiple myeloma and, in 2012, carfilzomib received accelerated approval by the US Food and Drug Administration (FDA). Driven by access to better drugs, median overall survival in younger patients (aged 10 years by 2014. The FDA approved 14 new drugs for the treatment of cancer in 2015; four of these were approved for the treatment of myeloma (panobinostat, daratumumab, elotuzumab and ixazomib). In 2015 and 2016, expanded label indications were approved by the FDA for lenalidomide and carfilzomib, respectively. The recent increase in approved, highly effective combination therapies for patients with multiple myeloma has led the way to redefining the goals of therapy. Here, we review and provide a clinical perspective on the treatment goals and management of multiple myeloma in the era of modern therapy. Recent meta-analyses show that minimal residual disease (MRD) negativity is associated with longer progression-free and overall survival in patients with multiple myeloma. With the use of modern combination therapy, large proportions (>60-70%) of newly diagnosed multiple myeloma patients achieve complete responses and MRD negativity. Modern combination therapies induce rapid, deep and sustainable responses (including MRD negativity), supporting a treatment paradigm shift away from palliative two-drug combinations towards the use of modern, potent, three- or four-drug combination regimens in early lines of therapy. Data support the use of modern therapy upfront rather than reserving it for later stages of the disease. As survival time increases with modern combination therapies, development of early reliable surrogate end-points for survival, such as MRD negativity, are needed for expedited read-out of future randomized clinical

    Full Text Available A 53–year-old man underwent right nephrectomy for a locally advanced renal cell carcinoma with concomitant resection of a solitary metastasis in the right lung. Ten years later, he presented with haematochezia caused by a tumour in the tail of pancreas, invading the transverse colon and the greater curvature of the stomach. The tumour was radically resected, and histological examination revealed a solitary metastasis of the previous renal cell carcinoma. This case illustrates a rare indication for pancreatic resection because of pancreatic metastasis.

    Full Text Available We report unexpectedly high efficacy of temsirolimus as third-line treatment in a patient with metastatic chromophobe renal cell carcinoma. After failure of two sequentially administered tyrosine kinase inhibitors, treatment with temsirolimus resulted in a prolonged partial remission of 14 months, and the response is still continuing. Up to now, no data from randomized clinical studies have been published addressing the question of efficacy of temsirolimus as third-line treatment after failure of tyrosine kinase inhibitors. The case presented here implies that temsirolimus could be a viable option for patients with metastatic chromophobe renal cell carcinoma.

    Multiple myeloma (MM) is a hematological malignancy, which remains incurable because most patients eventually relapse or become refractory to current treatments. Due to heterogeneity within the cancer cell microenvironment, cancer cell populations employ a dynamic survival strategy to chemotherapeutic treatments, which frequently results in a rapid acquisition of therapy resistance. Besides resistance-conferring genetic alterations within a tumor cell population selected during drug treatment, recent findings also reveal non-mutational mechanisms of drug resistance, involving a small population of "cancer stem cells" (CSCs) which are intrinsically more refractory to the effects of a variety of anticancer drugs. Other studies have implicated epigenetic mechanisms in reversible drug tolerance to protect the population from eradication by potentially lethal exposures, suggesting that acquired drug resistance does not necessarily require a stable heritable genetic alteration. Clonal evolution of MM cells and the bone marrow microenvironment changes contribute to drug resistance. MM-CSCs may not be a static population and survive as phenotypically and functionally different cell types via the transition between stem-like and non-stem-like states in local microenvironments, as observed in other types of cancers. Targeting MM-CSCs is clinically relevant, and different approaches have been suggested to target molecular, metabolic and epigenetic signatures, and the self-renewal signaling characteristic of MM CSC-like cells. Here, we summarize epigenetic strategies to reverse drug resistance in heterogeneous multiple myeloma.

    2 cases of multiple myeloma, both with IgG kappa, are reported in a man and his daughter. 33 other cases of myeloma involving two or more first degree relatives have been reported in the literature. Reported cases showed no major specific characteristics of the myelomas involved. Monoclonal protein family members were rarely identical. Our observation of identical monoclonal protein in two family members has only been found in 4 other reports. Occurrence of several cases of myeloma in one family is unlikely to be due to chance alone and the possibility of familial myeloma must be considered. Reports of benign monoclonal gammapathy in other members of the family of a patient with myeloma is also in favor of genetic factors. HLA-typing has shown an increase in frequency of the 4c complex and HLA-A9 in myeloma, and the latter was present in our patients. A genetic predisposition is further supported by experimental observations in mice. Finally, the short delay between onsets of myeloma in family members, less than 5 years in 20 families out of 27, and 4 years in our case, suggests a possible role of environmental factors.

    Birt-Hogg-Dubé (BHD) is a rare autosomal dominant inherited syndrome that is characterized by the presence of fibrofolliculomas and/or trichodiscomas, pulmonary cysts, spontaneous pneumothorax, and renal tumors. Here, the 2 patients we reported with renal cell carcinomas and dermatological features were suspected to be suffering from BHD syndrome. Blood samples of these patients were sent for whole exon sequencing performed by Sanger sequencing. Eight mutations, including 5 mutations, which were mapped in noncoding region, 1 synonymous mutation, and 2 missense mutations, were detected in the FLCN gene in both patients. The 2 missense mutations, predicted to be disease-causing mutation or affecting protein function by MutationTaster and SIFT, confirmed the diagnosis. In addition, the 2 patients were also affected with papillary thyroid cancer. Total thyroidectomy and prophylactic bilateral central lymph node dissection were performed for them and the BHD-2 also received lateral lymph node dissection. Pathology reports showed that the patients had lymph node metastasis in spite of small size of thyroid lesions.The 2 missense mutations, not reported previously, expand the mutation spectrum of FLCN gene associated with BHD syndrome. For the thyroid cancer patients with BHD syndrome, total thyroidectomy and prophylactic bilateral central lymph node dissection may be suitable and the neck ultrasound may benefit BHD patients and their family members.

    A 36 year old male presented to the emergency department with severe epigastric pain, nausea, vomiting without hematemesis, diarrhea and anorexia. He presented with respiratory distress, shock and fever at the emergency. He was intubated and shifted to the intensive care unit with the diagnosis of acute pancreatitis with hypercalcemia and an elevated amylase and lipase's well as thrombocytopenia and elevated creatinine. CT scan of abdomen was done which showed lytic bone lesions in the spine and necrosis of the pancrease. He was evaluated for multiple myeloma and it was confirmed in a bone marrow biopsy. Multiple myeloma usually is seen in patients aged more than 60 yrs. The typical presentation of multiple myeloma is anemia, back pain, and an elevated sedimentation rate. Patients with multiple myeloma have hypercalcemia but it's rarely manifested as acute pancreatitis. This case shows a rare presentation of multiple myeloma as acute pancreatitis in a younger adult.

    Pazopanib is an oral angiogenesis inhibitor, currently approved for treatment of metastatic renal cell carcinoma (mRCC) and soft tissue sarcoma. The present study analyzed the outcomes of pazopanib in first-line treatment of mRCC, in a single Italian cancer center. In the light of the retrospective, observational nature and the unselected population, our experience can be defined a “real-world” study. The medical records of 38 mRCC patients treated with front-line pazopanib were retrospectively reviewed and analyzed. The progression free survival (PFS) and the overall survival (OS) were the primary endpoints, while secondary objectives included objective response rate (ORR), disease control rate (DCR), and treatment tolerability. Pazopanib achieved a median PFS (mPFS) of 12.7 months (95% CI, 6.9–18.5 months). The median OS (mOS) was 26.2 months (95% CI, 12.6–39.9 months); the observed ORR and DCR were 30.3 and 72.7%, respectively, with a median duration of response of 11 weeks. mPFS appeared not to be influenced by number of co-morbidities (< 3 vs. ≥3), gender, Fuhrman grade and age. Conversely, the ORR and the DCR positively affect the mPFS (HR = 0.05 [95% CI, 0.05–0.55], p = 0.01; HR = 0.10 [95% CI, 0.02–0.43], p = 0.002, respectively). A worse outcome was associated with a lower mPFS in patients with liver metastases (p = 0.2) and with a high tumor burden (number of metastatic sites < 6 vs. ≥6) (p = 0.08). Worst OS was observed in patients aged ≥70 years old (HR = 6.91 [95% CI, 1.49–31.91], p = 0.01). The treatment was well-tolerated: no grade 4 adverse events, nor discontinuation due to toxicities was reported. Grade 3 hypertension affected positively the OS reaching the statistical significance (HR = 0.22 [95% CI, 0.05–0.8], p = 0.03). Thyroid dysfunction (hypo and hyperthyroidism) seems to correlate with better outcome in terms of a longer mPFS (HR = 0.12 [95% CI, 0.02–0.78], p = 0.02). Our results are consistent with those reported in

    Treatment for multiple myeloma (MM) has significantly advanced in the last decade with the introduction of proteasome inhibitors and immunomodulatory therapies. Unfortunately, MM continues to cause significant morbidity and most patients eventually succumb to the disease. As in other areas of cancer, immunotherapy in MM has also evolved and holds promise to deliver long-lasting remissions or even cure. The signaling lymphocyte activation molecules (SLAM) family of surface proteins represents a group of potential targets for immunotherapy in MM as some of the family members are expressed consistently on plasma cells and also on myeloma propagating pre-plasma cells. Here, we review the SLAM family members in detail, describe their tissue distribution, biologic pathways, as well as relevant pre-clinical studies and clinical trials in MM. Our review demonstrates the value of SLAM family receptors as potential targets for anti-myeloma immunotherapies and outlines how immunotherapeutic approaches can be developed.

    Despite recent progress in novel and targeted therapies, multiple myeloma (MM) remains a therapeutically challenging incurable disease. The regulation of important cellular processes and its link to cancer presented Src as an attractive target for MM. We suggest a novel strategy to improve the treatment of MM and overcome the drug resistance for the current therapeutic agents by specific inhibition of Src in MM cells by Tris (Dibenzylideneacetone) dipalladium (Tris DBA). Tris DBA reduces proliferation, induces G1 arrest and apoptosis in MM cells. Tris DBA showed additive effect with proteasome inhibitors reducing proliferation, cell cycle signaling, and increasing apoptosis more than each drug alone. Tris DBA overcame hypoxia-induced effects such as enhanced chemotaxis or drug resistance to proteasome inhibitors by inhibition of HIF1α expression. Moreover, we found that Tris DBA is an effective anti-myeloma agent alone or in combination with other targeted drugs and that it reverses hypoxia-induced drug resistance in myeloma.

    Renal cancer with lymph nodal mass on the investigation is clinically suggestive of an advanced tumor. Small renal cancers are not commonly associated with lymph nodal metastasis. Association of renal cell carcinoma with renal tuberculosis (TB) in the same kidney is also rare. We report here a case of small renal cancer with multiple hilar and paraaortic lymph nodes who underwent radical nephrectomy, and histopathology report showed renal and lymph nodal TB too.

    To investigate associations between imaging features and mutational status of clear cell renal cell carcinoma (ccRCC). This multi-institutional, multi-reader study included 103 patients (77 men; median age 59 years, range 34-79) with ccRCC examined with CT in 81 patients, MRI in 19, and both CT and MRI in three; images were downloaded from The Cancer Imaging Archive, an NCI-funded project for genome-mapping and analyses. Imaging features [size (mm), margin (well-defined or ill-defined), composition (solid or cystic), necrosis (for solid tumors: 0%, 1%-33%, 34%-66% or >66%), growth pattern (endophytic, <50% exophytic, or ≥50% exophytic), and calcification (present, absent, or indeterminate)] were reviewed independently by three readers blinded to mutational data. The association of imaging features with mutational status (VHL, BAP1, PBRM1, SETD2, KDM5C, and MUC4) was assessed. Median tumor size was 49 mm (range 14-162 mm), 73 (71%) tumors had well-defined margins, 98 (95%) tumors were solid, 95 (92%) showed presence of necrosis, 46 (45%) had ≥50% exophytic component, and 18 (19.8%) had calcification. VHL (n = 52) and PBRM1 (n = 24) were the most common mutations. BAP1 mutation was associated with ill-defined margin and presence of calcification (p = 0.02 and 0.002, respectively, Pearson's χ (2) test); MUC4 mutation was associated with an exophytic growth pattern (p = 0.002, Mann-Whitney U test). BAP1 mutation was associated with ill-defined tumor margins and presence of calcification; MUC4 mutation was associated with exophytic growth. Given the known prognostic implications of BAP1 and MUC4 mutations, these results support using radiogenomics to aid in prognostication and management.

    Epigenetic abnormalities are common in hematologic malignancies, including multiple myeloma, and their effects can be efficiently counteracted by a class of tumor suppressor miRNAs, named epi-miRNAs. Given the oncogenic role of histone deacetylases (HDAC) in multiple myeloma, we investigated whether their activity could be antagonized by miR-29b, a well-established epi-miRNA. We demonstrated here that miR-29b specifically targets HDAC4 and highlighted that both molecules are involved in a functional loop. In fact, silencing of HDAC4 by shRNAs inhibited multiple myeloma cell survival and migration and triggered apoptosis and autophagy, along with the induction of miR-29b expression by promoter hyperacetylation, leading to the downregulation of prosurvival miR-29b targets (SP1, MCL-1). Moreover, treatment with the pan-HDAC inhibitor SAHA upregulated miR-29b, overcoming the negative control exerted by HDAC4. Importantly, overexpression or inhibition of miR-29b, respectively, potentiated or antagonized SAHA activity on multiple myeloma cells, as also shown in vivo by a strong synergism between miR-29b synthetic mimics and SAHA in a murine xenograft model of human multiple myeloma. Altogether, our results shed light on a novel epigenetic circuitry regulating multiple myeloma cell growth and survival and open new avenues for miR-29b-based epi-therapeutic approaches in the treatment of this malignancy.

    Full Text Available Treatment of metastatic renal cell cancer (mRCC currently focuses on inhibition of the vascular endothelial growth factor pathway and the mammalian target of rapamycin (mTOR pathway. Obesity confers a higher risk of RCC. However, the influence of obesity on clinical outcomes in mRCC in the era of targeted therapy is less clear. This review focuses on the impact of body composition on targeted therapy outcomes in mRCC. The International Metastatic Renal Cell Carcinoma Database Consortium database has the largest series of patients evaluating the impact of body mass index (BMI on outcomes in mRCC patients treated with targeted therapy. Overall survival was significantly improved in overweight patients (BMI ≥ 25 kg/m2, and this observation was externally validated in patients who participated in Pfizer trials. In contrast, sarcopenia is consistently associated with increased toxicity to inhibitors of angiogenesis and mTOR. Strengthening patients with mRCC and sarcopenia, through a structured exercise program and dietary intervention, may improve outcomes in mRCC treated with targeted therapies. At the same time, the paradox of obesity being a risk factor for RCC while offering a better overall survival in response to targeted therapy needs to be further evaluated.

    The drugs used in chemotherapy treatments have little specificity, attack tumor cells, and also injure proliferative tissues. Knowledge of the functions of micronutrients has greatly increased, especially of Selenium (Se) that presents immunomodulatory and antitumor functions. The present study evaluated the health-related quality of life of patients undergoing chemotherapy for the treatment of leukemias and lymphomas (LL) and solid tumors (ST) while receiving Selenium (Se) supplementation. This is a randomized, double-blind, crossover study that evaluated the quality of life (EORTC-QLQ-C30 questionnaire), renal and liver functions of patients supplemented with Se. There was no statistically significant alteration in LL patients. However, the fatigue and nausea scores after 30 days did decrease in this group as well as in the ST group. After 1 year supplementation with Selenium, a more noticeable decrease in the scores concerning fatigue and nausea could be observed in the ST group, when compared with the beginning of the study. The LL patients also presented a decrease in the fatigue scores and physical functions. The kidney function as well as liver function has improved after Selenium supplementation when compared with the placebo intake in LL and ST patients, more remarkably in the LL group. Supplementation with Selenium promotes the reduction of chemotherapy side effects in cancer patients, especially by improving the conditions of patients with fatigue, nausea, and impaired physical function. Renal and liver functions have also improved.

    Renal cell carcinoma forming a venous tumor thrombus (VTT) in the inferior vena cava (IVC) has a poor prognosis. Recent investigations have been focused on prognostic markers of survival. Thrombus consistency (TC) has been proposed to be of significant value but yet there are conflicting data. The aim of this study is to test the effect of IVC VTT consistency on cancer specific survival (CSS) in a multi-institutional cohort. The records of 413 patients collected by the International Renal Cell Carcinoma-Venous Thrombus Consortium were retrospectively analyzed. All patients underwent radical nephrectomy and tumor thrombectomy. Kaplan-Meier estimate and Cox regression analyses investigated the impact of TC on CSS in addition to established clinicopathological predictors. VTT was solid in 225 patients and friable in 188 patients. Median CSS was 50 months in solid and 45 months in friable VTT. TC showed no significant association with metastatic spread, pT stage, perinephric fat invasion, and higher Fuhrman grade. Survival analysis and Cox regression rejected TC as prognostic marker for CSS. In the largest cohort published so far, TC seems not to be independently associated with survival in RCC patients and should therefore not be included in risk stratification models. J. Surg.

    We examined the population-based rates of cancer-specific survival in patients with metastatic renal cell carcinoma (MRCC) treated with either partial (PN) or radical cytoreductive nephrectomy (RN). Patients diagnosed with MRCC and treated with either PN or RN were identified within nine SEER cancer registries. Matched and unmatched Kaplan-Meier survival analyses, as well as multivariable Cox regression models compared the effect of RN (n = 1997, 97.8%) vs. PN (n = 46, 2.2%) on cancer-specific survival (CSS). Covariates consisted of age, gender, community type (rural vs urban), race, Surveillance, Epidemiology, and End Results (SEER) registry, tumor size and year of diagnosis. In multivariable unmatched Cox regression analyses, no statistically significantly difference was found in CSS between the two groups (hazard ratio [HR] 1.40, P = .16). Similarly, no difference in CSS was found in the matched analyses (HR 1.35, log rank P = .34). Cytoreductive PN does not appear to undermine survival in patients with MRCC.

    Addison's disease is a rare condition. Its onset of symptoms most often is nonspecific contributing to a diagnostic and therapeutic delay. Acute renal failure can be the first manifestation of this disease. We report the case of a patient with Addison's disease who was initially treated for acute renal failure due to multiple myeloma and whose diagnosis was adjusted thereafter. Patient's condition dramatically improved after treatment with intravenous rehydration; injectable hydrocortisone.

    Cancer chemotherapy resistance is always a problem that is not clear considering spatial heterogeneity in the tumor microenvironment. We culture multiple myeloma in a gradient from 0 to 20 nM of doxorubicin (genotoxic drug) across 2 mm wide region in a microfluidic device which mimics the tumor microenvironment with a chemotherapy drug gradient and microhabitats. Resistance of the multiple myeloma cells to doxorubicin emerged within two weeks. For the resistant cells evolved from the devices, the doxorubicin concentration that inhibits 50% of the controlled population increased by 16-fold than the parental cells. Whole transcriptome sequencing revealed that 39% of newly acquired mutational hotspots (the genes with more than 3 non-synonymous point mutation) of the resistant cells are involved in apoptosis and DNA repair. On the other hand, 40% of the non-mutated genes that are abnormally regulated in the resistant cells, are involved in metabolism, biosynthesis, and biomolecular transport. Among them, metabolic drug efflux pumps and oxidative stress scavengers are up-regulated to reduce the cytotoxicity of doxorubicin and further result in the resistance. The roles of the spatial drug gradients and microhabitats in rapid emergence of cancer resistance will be discussed. The project described was supported by the National Science Foundation and the National Cancer Institute.

    The patient was 68-year-old who underwent left upper lobectomy and lymph node dissection. On the 4th postoperative day, he developed vomiting and lumbar pain. On 5th postoperative day, he complained of pain, sensory paralysis and cold sensation of the right lower extremity. Computed tomography(CT)examination revealed left renal infarction and acute arterial obstruction of the right common iliac artery. Emergency thrombectomy of the right lower extremity was performed. Postoperatively, he received anticoagulant therapy and was able to leave the hospital on the 20th postoperative day. Attention should be paid to the infarction of abdominal organs when developing abdominal symptoms after lung cancer surgery in elderly patients.

    Hepatocellular carcinoma (HCC) and renal cell cancer (RCC) are malignancies, which are chemotherapy resistant and fatal at the advanced stages. Previously developed tyrosine kinase inhibitors are used in the treatment of advanced stage disease. In the present case study, a patient using sunitinib for stage IV RCC presented with HCC following 2 years of treatment. A patient who exhibited Child-Pugh class C cirrhosis initially, exhibited a marked improvement of hepatocellular parenchyma findings following treatment with sunitinib. Sunitinib is suggested to have preventive effects on the pathogenesis of liver fibrosis and cirrhosis in vitro, via an anti-vascular endothelial growth factor and anti-platelet-derived growth factor mechanism. However, no clinical supportive study has been performed until now. Improvement of liver functions may be explained in this manner. Therefore, investigations are required with different doses of sunitinib and other tyrosine kinase inhibitors in order to evaluate the efficacy on treatment of cirrhosis progression. PMID:26893877

    8000 cases of renal cancer are diagnosed each year in the UK, with a five-year survival rate of 50%. Treatment options are limited; a potential therapeutic target is the Src family kinases (SFKs). SFKs have roles in multiple oncogenic processes and promote metastases in solid tumours. The aim of this study was to investigate SFKs as potential therapeutic targets for clear cell renal cell carcinoma (ccRCC). SFKs expression was assessed in a tissue microarray consisting of 192 ccRCC patients with full clinical follow-up. SFK inhibitors, dasatinib and saracatinib, were assessed in early ccRCC cell lines, 786-O and 769-P and a metastatic ccRCC cell line, ACHN (± Src) for effects on protein expression, apoptosis, proliferation and wound healing. High nuclear expression of Lyn and the downstream marker of activation, paxillin, were associated with decreased patient survival. Conversely, high cytoplasmic expression of other SFK members and downstream marker of activation, focal adhesion kinase (FAK) were associated with increased patient survival. Treatment of non-metastatic 786-O and 769-P cells with dasatinib, dose dependently reduced SFK activation, shown via SFK (Y(419)) and FAK (Y(861)) phosphorylation, with no effect in metastatic ACHN cells. Dasatinib also increased apoptosis, while decreasing proliferation and migration in 786-O and 769-P cell lines, both in the presence and absence of Src protein. Our data suggests that nuclear Lyn is a potential therapeutic target for ccRCC and dasatinib affects cellular functions associated with cancer progression via a Src kinase independent mechanism.

    Hyperlipidemic myeloma is a rare and poorly understood variant of multiple myeloma. We report the case of a 53-year-old woman with hyperlipidemic myeloma, skin xanthomas and hyperviscosity syndrome who underwent allogeneic bone marrow transplantation. A comprehensive literature search identified 52 additional cases with plasma cell disease and hyperlipidemia. A detailed analysis revealed several characteristics of these patients as compared to multiple myeloma with normal lipid status: (1) IgA paraprotein was present in the majority (53% vs. 21% in classical multiple myeloma). (2) Skin xanthomas, especially in the palmar creases, elbows, and knees were common (70%). (3) Hyperviscosity syndrome occurred more often (26% vs. 2-6%). While conventional lipid-lowering therapy had only marginal effects, successful anti-myeloma therapy also reduced hyperlipidemia. Analyses of the mechanisms leading to hyperlipidemia documented complexes of paraprotein and lipoprotein in 75% of the 32 cases tested, suggesting an inhibitory role of the paraprotein on lipid degradation. In conclusion, the clinical characteristics, the therapeutic options, and the pathophysiologic mechanisms of hyperlipidemic myeloma are comprehensively reported using the available data from all 53 published cases in the literature.

    Full Text Available Introduction. Immunoglobulin D (IgD myeloma is a rare disease, about 2% of all myelomas, even rarer when accompanied with another multiple myeloma in biclonal gammopathy. We presented a case of biclonal gammopathy - associated manifestation of IgD myeloma and light chain disease in a patient who initially had renal failure. Case report. 37-year-old male approximately one month before hospitalization began to feel malaise and fatigue along with decreased urination. Laboratory analysis revealed azotemia. A dialysis catheter was placed and hemodialysis started. The patient was then admitted to our hospital for further tests and during admission, objective examination revealed pronounced paleness with hepatosplenomegaly and hypertension (170/95 mmHg. Laboratory analysis showed erythrocyte sedimentation rate 122 mm/h, expressed anemic syndrome (Hb 71 g/L and renal failure dialysis rank: creatinine 1,408 μmol/L, urea31.7 mmol/L. There was two M components in serum protein electrophoresis: IgD lambda and free light chain lambda. Proteinuria was nephrotic rank (5.4 g/24 h, whose electrophoresis revealed 2 M components - massive in α 2 fraction of 71%; 7% in the discrete β fraction, beta 2M /serum 110 mg/L, in urine 1.8 mg/L - extremely high; IgL kappa / lambda index 1 : 13 (reference value ratio 2 : 1. The findings pointed to double myeloma disease: IgD myeloma and Bence Jones lambda myeloma. Bone biopsy confirmed IgD myeloma lambda 100% infiltration medulla predominantly plasmablasts. The treatment continued with hemodialysis 3 times per week with chemotherapy protocol bortezomib, doxorubicin, dexamethasone. After 4 cycles of chemotherapy, there was a decrease of IgD, λ - light chains, reduction in proteinuria (1.03 g/24 h, so hemodialysis was reduced to once per week. Six months after treatment initiation the patient underwent autologous bone marrow transplantation. In a 2-year follow-up period double myeloma disease showed complete remission

    Cereblon was identified as a direct target of thalidomide by Prof. H. Handa, and this pioneering work triggered active research on IMiDs (immunomodulatory drugs), which include thalidomide-derivatives, such as lenalidomide and pomalidomide. These small molecules have been shown to bind to cereblon (CRBN) to modulate its activity as a substrate receptor. In addition, structural analyses on CRBN have revealed unique actions of these small agents, by which degradation of transcription factors is controlled in a specific and unique way. I summarize recent progress on CRBN-CRLA ubiquitin ligase and IMiDs, focusing on the therapeutic application of these drugs for treatment of multiple myeloma.

    2008-01-01

    Constitutive activation of the transcription factor STAT3 contributes to the pathogenesis of many cancers, including multiple myeloma (MM). Since STAT3 is dispensable in most normal tissue, targeted inhibition of STAT3 is an attractive therapy for patients with these cancers. To identify STAT3 inhibitors, we developed a transcriptionally based assay and screened a library of compounds known to be safe in humans. We found the drug nifuroxazide to be an effective inhibitor of STAT3 function. Ni...

    Adults with chronic immunosuppressive conditions are at an increased risk for Streptococcus agalactiae endocarditis, which is typically characterized by acute onset, presence of large vegetations, rapid valvular destruction and frequent complications. We report a rare case of a 74 years old man presenting with fever, renal infarction, ischemic stroke and uveitis. Infective endocarditis was diagnosed and Streptococcus agalactiae was isolated in blood cultures. A multiple myeloma Ig G-K was also diagnosed. The infective endocarditis was successfully treated with a course of benzylpenicillin and gentamicin. The authors highlight the severity of vascular embolic disease present in this case and the diagnostic challenge. They also intend to remind about the association between Streptococcus agalactiae endocarditis and chronic diseases, despite its low reported prevalence.

    2009-01-01

    Although plasma cell infiltration is not rare in autopsy of patients with multiple myeloma (MM), it is very rarely detected in living patients. This is because MM rarely causes significant liver dysfunction that requires further evaluation. A 49-year-old man presented with acute renal failure and was diagnosed with kappa light chain MM stage ?B. Thalidomide and dexamethasone were initiated. The patient developed a continuous increase in bilirubin that led to severe cholestasis. A liver biopsy revealed plasma cell infiltration. He then rapidly progressed to liver failure and died. Treatment options are limited in MM with significant liver dysfunction.Despite new drug therapies in MM, those patients with rapidly progressive liver failure appear to have a dismal outcome.

    Full Text Available Multiple myeloma represents a malignant proliferation of plasma cells derived from a single clone. The tumor, its products and the host response to it result in a number of organ dysfunctions and symptoms of bone pain, fracture, anemia, hypercalcemia, susceptibility to infection, neurologic symptoms, clotting abnormalities and manifestations of hyperviscosity. The cause of myeloma remains unexplained but it is associated with few occupations, inflammatory conditions, autoimmune illnesses, viral infections and genetic heterogeneity. Direct interaction between multiple myeloma cells and bone marrow cells activates pleiotropic signalling pathways that mediate growth, survival, migration of multiple myeloma cells and also resistance to chemotherapy. Although myeloma remains incurable, but the use of novel drugs like thalidomide, lenalidomide and bortezomib have resulted in a paradigm change in the therapy of myeloma. Their inclusion in current multiple myeloma treatment regimens have extended median overall survival especially in younger patient population. Recent advances in the molecular genetics have provided opportunities to design highly specific inhibitors of signal transduction pathways that may enhance the efficacy of standard chemotherapy drugs by reducing or altering the pathways associated with cell survival. Despite therapeutic advances, multiple myeloma ultimately relapses and remains an incurable disease. Current research goals are to further increase our knowledge, to identify additional targeted therapies, and to reduce adverse effects and improve response rate. This review focuses on recent clinical advancement in ant myeloma strategies with additional discussion dedicated to emerging drugs that may prove beneficial to patients with this disease.

    Human placenta has emerged as a valuable source of transplantable cells of mesenchymal and hematopoietic origin for multiple cytotherapeutic purposes, including enhanced engraftment of hematopoietic stem cells, modulation of inflammation, bone repair, and cancer. Placenta-derived adherent cells (PDACs) are mesenchymal-like stem cells isolated from postpartum human placenta. Multiple myeloma is closely associated with induction of bone disease and large lytic lesions, which are often not repaired and are usually the sites of relapses. We evaluated the antimyeloma therapeutic potential, in vivo survival, and trafficking of PDACs in the severe combined immunodeficiency (SCID)–rab model of medullary myeloma-associated bone loss. Intrabone injection of PDACs into non-myelomatous and myelomatous implanted bone in SCID-rab mice promoted bone formation by stimulating endogenous osteoblastogenesis, and most PDACs disappeared from bone within 4 weeks. PDACs inhibitory effects on myeloma bone disease and tumor growth were dose-dependent and comparable with those of fetal human mesenchymal stem cells (MSCs). Intrabone, but not subcutaneous, engraftment of PDACs inhibited bone disease and tumor growth in SCID-rab mice. Intratumor injection of PDACs had no effect on subcutaneous growth of myeloma cells. A small number of intravenously injected PDACs trafficked into myelomatous bone. Myeloma cell growth rate in vitro was lower in coculture with PDACs than with MSCs from human fetal bone or myeloma patients. PDACs also promoted apoptosis in osteoclast precursors and inhibited their differentiation. This study suggests that altering the bone marrow microenvironment with PDAC cytotherapy attenuates growth of myeloma and that PDAC cytotherapy is a promising therapeutic approach for myeloma osteolysis.

    2015-03-01

    Full Text Available Acromegaly is a slowly progressing condition resulting from excess growth hormone (GH, generally caused by a GH-secreting pituitary adenoma. Cancer is the third most common cause of mortality in patients with acromegaly, and insulin-like growth factor 1 (IGF-1 is known to influence tumor formation by increasing cell proliferation and inhibiting apoptosis. Multiple myeloma (MM is a plasma cell neoplasm, and previous studies have suggested the possible role of IGF-1 in its development of MM. However, no cases of acromegaly accompanied with MM have been reported in Asia to date. We here report the case of a 58-year-old woman with acromegaly accompanied with MM who presented with longstanding acromegalic manifestations resulting from a GH-secreting pituitary adenoma and also exhibited anemia, a reversed albumin/globulin ratio, and plasmacytosis on bone marrow examination. Because IGF-1 has been suggested to play an important role in the development and progression of MM, the patient promptly underwent surgical removal of the pituitary adenoma via a transsphenoidal approach. Since there is currently no consensus on therapeutic guidelines and suggested prognosis for MM with acromegaly, long-term follow-up of such cases is needed.

    Full Text Available Cytokines are wide-range modifiers of biological reactions. Cytokine regulation provides proliferation, differentiation, cell function, cell-cell and inter-systemic interaction, direction and nature of immune response to invasion of infectious and non-infectious pathogens. There are several distinct groups of cytokines: pro-inflammatory, anti-inflammatory factors, regulators of cellular and humoral immunity etc. A distinct role of cytokines is not excluded for infectious complications accompanying multiple myeloma (MM. Cytokine regulatory effects on immune defense in the organism as a whole, and a balance between proand anti-inflammatory cytokines in blood of MM patients depend on the stage of multiple myeloma progression and possibility of infectious complications. Therefore, the aim of our study was to evaluate proand anti-inflammatory cytokines and cytokine regulation in patients with MM G-immunochemical option. Our study involved 101 patients with MM (IgG-variant, their age ranging between 40 and 76 years. The diagnosis was verified by clinical and laboratory examinations. The G-variant of MM was verified by immunofixation and electrophoresis. The definite diagnosis and disease staging was confirmed by a combination of diagnostic criteria. Heparinized blood samples were taken from the cubital vein in the morning (8 to 9 hours, in fasting state upon admission, prior to the starting a pathogenetic therapy. Dynamic monitoring of patients was carried out over the period of their staying in hospital. All patients were staged according to Durie and Salmon (1975 (stages II, III. At each stage, we discerned two sub-groups: A, without renal disease, B, with renal impairment. The control group consisted of 125 healthy volunteers matched for age and sex with the main group. IL-2, IL-4, IL-8, TNFα, and IFNγ levels in sera of the patients and healthy individuals were determined by enzyme immunoassay kits (JSC “Vector-Best”,Novosibirsk. In the

    Full Text Available Drug reaction with eosinophilia and systemic symptoms (DRESS or drug-induced hypersensitivity is a severe adverse drug-induced reaction. Aromatic anticonvulsants, such as phenytoin, phenobarbital, and carbamazepine, and some drugs, can induce DRESS. Atypical crystalluria can be seen in patients treated with amoxycillin or some drugs and can cause acute renal failure. We describe a 66-year-old man who presented fever and rash and acute renal failure three days after starting amoxycillin. He was also using phenytoin because of cerebral metastatic lung cancer. Investigation revealed eosinophilia and atypical crystalluria. The diagnosis of DRESS syndrome was made, amoxicillin was stopped, and dose of phenytoin was reduced. No systemic corticosteroid therapy was prescribed. Symptoms began to resolve within three to four days. The aim of this paper is to highlight the importance of microscopic examination of urine in a case with acute renal failure and skin lesions to suspect DRESS syndrome.

    2016-01-01

    Full Text Available Multiple myeloma, a plasma cell neoplasm, presents most commonly with anemia, hypercalcemia, renal failure, and bone pain. Only few cases of clinical aggressive presentation associated with bleeding were reported in the medical literature. The reported cases included gastrointestinal bleeding and cardiac tamponade. Spontaneous retroperitoneal haemorrhage as initial presentation has not been so far reported. We hereby report a case of a 64-year-old female who was found to have catastrophic hemorrhage in the retroperitoneal region that extended into intrathecal space causing cord compression. The case posed a significant diagnostic and management dilemma. This case emphasizes the need to think broadly and include multiple myeloma in the diagnosis of unexplained massive retroperitoneal bleeding.

    2015-01-01

    Full Text Available Multiple myeloma is a neoplastic plasma cell disorder. It is characterized by collections of abnormal plasma cells accumulating in the bone marrow, where they interfere with the production of normal blood cells. It usually presents as a multisystemic involvement, whose symptoms and signs vary greatly. Some patients have slowly progressive disease while others have aggressive clinical behavior by extramedullary involvement. In addition to renal failure, anemia, hypercalcemia, lytic bone lesions, and immunodeficiency, it also affects multiple organ system, such as pancreas, adrenal glands, kidney, skin, lung, liver, spleen, lymph nodes, and bone. To raise awareness of the variable presentations of this disease, we report a 53-year-old male patient, with multiple myeloma in his first remission who relapsed with extramedullary plasmacytomas (EMPs involving multiple organs, such as pancreas, adrenal glands, kidney, skin, lung, liver, spleen, and lymph nodes.

    Full Text Available So far six susceptibility loci for renal cell carcinoma (RCC have been discovered by genome-wide association studies (GWAS. To identify additional RCC common risk loci, we performed a meta-analysis of published GWAS (totalling 2,215 cases and 8,566 controls of Western-European background with imputation using 1000 Genomes Project and UK10K Project data as reference panels and followed up the most significant association signals [22 single nucleotide polymorphisms (SNPs and 3 indels in eight genomic regions] in 383 cases and 2,189 controls from The Cancer Genome Atlas (TCGA. A combined analysis identified a promising susceptibility locus mapping to 1q24.1 marked by the imputed SNP rs3845536 (Pcombined =2.30x10-8. Specifically, the signal maps to intron 4 of the ALDH9A1 gene (aldehyde dehydrogenase 9 family, member A1. We further evaluated this potential signal in 2,461 cases and 5,081 controls from the International Agency for Research on Cancer (IARC GWAS of RCC cases and controls from multiple European regions. In contrast to earlier findings no association was shown in the IARC series (P=0.94; Pcombined =2.73x10-5. While variation at 1q24.1 represents a potential risk locus for RCC, future replication analyses are required to substantiate our observation.

    Renal cell cancer (RCC) incidence varies worldwide with a higher incidence in developed countries and lifestyle is likely to contribute to the development of this disease. We examined whether meat and fish consumption were related to the risk of RCC in the European Prospective Investigation into Cancer and Nutrition (EPIC). The analysis included 493,179 EPIC participants, recruited between 1992 and 2000. Until December 2008, 691 RCC cases have been identified. Meat and fish consumption was assessed at baseline using country-specific dietary assessment instruments; 24-hour recalls were applied in an 8% subsample for calibration purposes. Cox proportional hazards regression was used to calculate multivariable-adjusted hazard ratios (HR) and 95% confidence intervals (CI). Women with a high consumption of red meat (HR = 1.36, 95% CI 1.14-1.62; calibrated, per 50 g/day) and processed meat (HR = 1.78, 95% CI 1.05-3.03; calibrated, per 50 g/day) had a higher risk of RCC, while no association existed in men. For processed meat, the association with RCC incidence was prominent in premenopausal women and was lacking in postmenopausal women (p interaction = 0.02). Neither poultry nor fish consumption were statistically significantly associated with the risk of RCC. The results show a distinct association of red and processed meat consumption with incident RCC in women but not in men. A biological explanation for these findings remains unclear.

    Full Text Available Abstract Background Kidney and renal pelvis cancers account for 4% of all new cancer cases in the United States, among which 85% are renal cell carcinomas (RCC. While cigarette smoking is an established risk factor for RCC, little is known about the contribution of environmental tobacco smoke (ETS to RCC incidence. This study assesses the role of smoking and ETS on RCC incidence using a population-based case-control design in Florida and Georgia. Methods Incident cases (n = 335 were identified from hospital records and the Florida cancer registry, and population controls (n = 337 frequency-matched by age (+/- 5 years, gender, and race were identified through random-digit dialing. In-person interviews assessed smoking history and lifetime exposure to ETS at home, work, and public spaces. Home ETS was measured in both years and hours of exposure. Odds ratios and 95% confidence intervals were calculated using logistic regression, controlled for age, gender, race, and BMI. Results Cases were more likely to have smoked 20 or more pack-years, compared with never-smokers (OR: 1.35, 95% CI: 0.93 – 1.95. A protective effect was found for smoking cessation, beginning with 11–20 years of cessation (OR: 0.39, 95% CI: 0.18–0.85 and ending with 51 or more years of cessation (OR: 0.11, 95% CI: 0.03–0.39 in comparison with those having quit for 1–10 years. Among never-smokers, cases were more likely to report home ETS exposure of greater than 20 years, compared with those never exposed to home ETS (OR: 2.18; 95% CI: 1.14–4.18. Home ETS associations were comparable when measured in lifetime hours of exposure, with cases more likely to report 30,000 or more hours of home ETS exposure (OR: 2.37; 95% CI: 1.20–4.69. Highest quartiles of combined home/work ETS exposure among never-smokers, especially with public ETS exposure, increased RCC risk by 2 to 4 times. Conclusion These findings confirm known associations between smoking and RCC and establish a

    This study sought to identify occupations with high incidence of multiple myeloma and to investigate possible excess risk associated with occupational exposure to chemicals and sensitizing agents in Sweden. A historical cohort of 2,992,166 workers was followed up (1971--1989) through record linkage with the National Cancer and Death Registries. For each job category, age and period standardized incidence ratios and age and period adjusted relative risks of multiple myeloma were calculated using Poisson models. Exposure to chemicals and to sensitizing agents was also assessed using two job-exposure matrices. Men and women were analyzed separately. During follow-up, 3,127 and 1,282 myelomas were diagnosed in men and women, respectively. In men, excess risk was detected among working proprietors, agricultural, horticultural and forestry enterprisers, bakers and pastry cooks, dental technicians, stone cutters/carvers, and prison/reformatory officials. In women, this excess was observed among attendants in psychiatric care, metal workers, bakers and pastry cooks, and paper/paperboard product workers. Workers, particularly bakers and pastry cooks, exposed to high molecular weight sensitizing agents registered an excess risk of over 40% across the sexes. Occasional, although intense, exposure to pesticides was also associated with risk of myeloma in our cohort. Our study supports a possible etiologic role for farming and use of pesticides in myeloma risk. The high incidence found in both female and male bakers and pastry cooks has not been described previously. Further research is required to assess the influence of high molecular weight sensitizing agents on risk of multiple myeloma.

    Macrophages play an important role in cancer by suppression of adaptive immunity and promotion of angiogenesis and metastasis. Tumor-associated macrophages strongly express the hemoglobin scavenger receptor CD163, which can also be found as a soluble protein in serum and other body fluids (soluble CD163, sCD163). In this study, we examined serum sCD163 as a biomarker in patients with newly diagnosed multiple myeloma. Peripheral blood (n = 104) and bone marrow (n = 17) levels of sCD163 were measured using an enzyme-linked immunosorbent assay. At diagnosis, high sCD163 was associated with higher stage according to the International Staging System (ISS) and with other known prognostic factors in multiple myeloma (creatinine, C-reactive protein, and beta-2 microglobulin). Soluble CD163 decreased upon high-dose treatment, and in a multivariate survival analysis including the covariates treatment modality and age at diagnosis, higher levels of sCD163 were associated with poor outcome (HR = 1.82; P = 0.010). The prognostic significance of sCD163 was lost when including ISS stage in the model (HR = 1.51; P = 0.085). Soluble CD163 values were significantly higher in bone marrow samples than in the matched blood samples, which indicate a localized production of sCD163 within the bone marrow microenvironment. Soluble CD163 was found to be a prognostic marker in patients with multiple myeloma. This may indicate that macrophages and/or monocytes have an important role in the bone marrow microenvironment of myeloma patients, supporting myeloma cell proliferation and survival. We propose the serum sCD163 value 1.8 mg/L as a cutoff concentration for survival analysis in patients with multiple myeloma, which should be validated in future studies. © 2014 John Wiley & Sons A/S.

    The concept of the myeloma stem cell may have important therapeutic implications, yet its demonstration has been hampered by a lack of consistency in terms and definitions. Here, we summarize the current documentation and propose single-cell in vitro studies for future translational studies....... By the classical approach, a CD19(-)/CD45(low/-)/CD38(high)/CD138(+) malignant plasma cell, but not the CD19(+)/CD38(low/-) memory B cell compartment, is enriched for tumorigenic cells that initiate myeloma in xenografted immunodeficient mice, supporting that myeloma stem cells are present in the malignant PC...... anticipate that further characterization will require single cell geno- and phenotyping combined with clonogenic assays. To implement such technologies, we propose a revision of the concept of a myeloma stem cell by including operational in vitro assays to describe the cellular components of origin...

    Based on their tumor tropism, mesenchymal stem cells (MSCs) have been proposed as carriers of cytotoxic molecules in pioneering strategies of anti-cancer gene therapy. Similar to solid tumors, MSCs, genetically modified to stably express the TNF-related apoptosis-inducing ligand (TRAIL), have been applied to counter-attack multiple myeloma (MM) in vitro and envisioned as a promising strategy for future anti-MM treatments. Accumulating evidence based on the detection of genetic and functional abnormalities in MSCs from MM patients points to the supportive function of MSCs in both the development and progression of MM, driven by chronic interplays with malignant cells within the marrow milieu. In this review, we revisit the function of MSCs in the pathophysiology of MM and explore the pivotal mechanisms of their interaction with myeloma cells. We also discuss the therapeutic significance of novel strategies using TRAIL-engineered MSCs in this cancer model, dissecting their role as new tools for future treatments against MM. A cytotherapy based on TRAIL-engineered MSCs against MM may be successfully combined with either conventional approaches of autologous stem cell transplantation or with novel anti-MM drugs. Intensive preclinical investigations are required to identify the best sources as well as modalities of MSC administration, thus defining the translational suitability of this strategy in the clinical setting.

    Purpose We evaluated the efficacy and toxicity of mammalian target rapamycin inhibitors in Korean patients with metastatic renal cell carcinoma (mRCC) with chronic renal insufficiency not requiring dialysis. Materials and Methods Korean patients with mRCC and chronic renal insufficiency not requiring dialysis treated with everolimus or temsirolimus between January 2008 and December 2014 were included. Patient characteristics, clinical outcomes, and toxicities were evaluated. Overall survival (OS) and progression-free survival (PFS) durations were evaluated according to the degree of renal impairment. Results Eighteen patients were considered eligible for the study (median age, 59 years). The median glomerular filtration rate was 51.5 mL/min/1.73 m2. The best response was partial response in six patients and stable disease in 11 patients. The median PFS and OS durations were 8 months (95% confidence interval [CI], 0 to 20.4) and 32 months (95% CI, 27.5 to 36.5), respectively. The most common non-hematologic and grade 3/4 adverse events included stomatitis, fatigue, flu-like symptoms, and anorexia as well as elevated creatinine level. Conclusion Mammalian target rapamycin inhibitors were efficacious and did not increase toxicity in Korean patients with mRCC and chronic renal insufficiency not requiring dialysis. PMID:26875195

  19. Cancer drug troglitazone stimulates the growth and response of renal cells to hypoxia inducible factors

    Energy Technology Data Exchange (ETDEWEB)

    Taub, Mary, E-mail: biochtau@buffalo.edu

    2016-03-11

    Troglitazone has been used to suppress the growth of a number of tumors through apoptosis and autophagy. However, previous in vitro studies have employed very high concentrations of troglitazone (≥10{sup −5} M) in order to elicit growth inhibitory effects. In this report, when employing lower concentrations of troglitazone in defined medium, troglitazone was observed to stimulate the growth of primary renal proximal tubule (RPT) cells. Rosiglitazone, like troglitazone, is a thiazolidinedione (TZD) that is known to activate Peroxisome Proliferator Activated Receptor Υ (PPARΥ). Notably, rosiglitazone also stimulates RPT cell growth, as does Υ-linolenic acids, another PPARΥ agonist. The PPARΥ antagonist GW9662 inhibited the growth stimulatory effect of troglitazone. In addition, troglitazone stimulated transcription by a PPAR Response Element/Luciferase construct. These results are consistent with the involvement of PPARΥ as a mediator of the growth stimulatory effect of troglitazone. In a number of tumor cells, the expression of hypoxia inducible factor (HIF) is increased, promoting the expression of HIF inducible genes, and vascularization. Troglitazone was observed to stimulate transcription by a HIF/luciferase construct. These observations indicate that troglitazone not only promotes growth, also the survival of RPT cells under conditions of hypoxia. - Highlights: • Troglitazone and rosiglitazone stimulate renal proximal tubule cell growth. • Troglitazone and linolenic acid stimulate growth via PPARϒ. • Linolenic acid stimulates growth in the presence of fatty acid free serum albumin. • Rosiglitazone stimulates transcription by a HRE luciferase construct.

    The diffuse infiltration by plasma cells in the liver is not uncommon in multiple myeloma (MM). However, a MM with hepatic mass is very unusual. We report a case of a 75-year-old male with hepatomegaly and a lesion occupying a voluminous space in the liver. A lambda light chain multiple myeloma was found in the check-up of this hepatic mass. We also provide a literature review.

  1. The FUSE binding proteins FBP1 and FBP3 are potential c-myc regulators in renal, but not in prostate and bladder cancer

    2008-12-01

    Full Text Available Abstract Background The three far-upstream element (FUSE binding proteins (FBP1, FBP2, and FBP3 belong to an ancient family of single-stranded DNA binding proteins which are required for proper regulation of the c-myc proto-oncogene. Whereas it is known that c-myc alterations play a completely different role in various carcinomas of the urogenital tract, the relevance of FBPs is unclear. Methods FBP1, FBP3 and c-myc expression was studied in 105 renal cell, 95 prostate and 112 urinary bladder carcinomas by immunohistochemistry using tissue microarrays. Results High rates of FBP1 and FBP3 expression were observed in all cancer types. There was a concomitant up-regulation of FBP1 and FBP3 in renal cell and prostate carcinomas (p C-myc expression was detectable in 21% of prostate, 30% of renal and 34% of urothelial carcinomas. Interestingly, strong FBP1 and FBP3 expression was associated with c-myc up-regulation in clear cell renal cell carcinomas (p Conclusion The correlation between FBP1/FBP3, c-myc and high proliferation rate in renal cell carcinoma provides strong in vivo support for the suggested role of FBP1 and FBP3 as activators of c-myc. The frequent up-regulation of FBP1 and FBP3 in urothelial and prostate carcinoma suggests that FBPs also have an important function in gene regulation of these tumors.

    Renal cell cancer patients with brain metastatic disease generally have poor prognosis. Treatment options include surgery, radiotherapy, targeted therapy or best supportive care with respect to disease burden, patient preference and performance status. In the present case report the radiotherapy technique combining whole brain radiotherapy with hippocampal sparing (hippocampal avoidance whole brain radiotherapy HA-WBRT) and hypofractionated stereotactic radiotherapy (SRT) of the brain metastases is performed in a patient with metastatic renal cell carcinoma. HA-WBRT was administered to 30 Gy in 10 fractions with sparing of the hippocampal structures and SRT of 21 Gy in 3 fractions to brain metastases which has preceded the HA-WBRT. Two single arc volumetric modulated arc radiotherapy (VMAT) plans were prepared using Monaco planning software. The HA-WBRT treatment plan achieved the following results: D2=33.91 Gy, D98=25.20 Gy, D100=14.18 Gy, D50=31.26 Gy. The homogeneity index was calculated as a deduction of the minimum dose in 2% and 98% of the planning target volume (PTV), divided by the minimum dose in 50% of the PTV. The maximum dose to the hippocampus was 17.50 Gy and mean dose was 11.59 Gy. The following doses to organs at risk (OAR) were achieved: Right opticus Dmax, 31.96 Gy; left opticus Dmax, 30.96 Gy; chiasma D max, 32,76 Gy. The volume of PTV for stereotactic radiotherapy was 3,736 cm3, with coverage D100=20.95 Gy and with only 0.11% of the PTV being irradiated to dose below the prescribed dose. HA-WBRT with SRT represents a feasible technique for radiotherapy of brain metastatic disease, however this technique is considerably demanding on departmental equipment and staff time/experience.

    To our knowledge, the impact of venous tumour thrombus (VTT) consistency in patients affected by renal cell carcinoma (RCC) has never been addressed. To analyse the effect of VTT consistency on cancer-specific survival (CSS). We retrospectively analysed 174 consecutive patients with RCC and renal vein or inferior vena cava (IVC) VTT who underwent surgical treatment between 1989 and 2007 at our institute. All patients underwent radical nephrectomy and thrombectomy. Pathologic specimens were reviewed by a single uropathologist. In addition to traditional pathologic features, the morphologic aspect of the tumour thrombus was evaluated to distinguish solid from friable patterns. The prognostic role of thrombus consistency (solid vs friable) on CSS was assessed by means of Cox regression models. The VTT was solid in 107 patients (61.5%) and friable in 67 patients (38.5%). The presence of a friable VTT increased the risk of having synchronous nodal or distant metastases, higher tumour grade, higher pathologic stage, and simultaneous perinephric fat invasion (all p VTT and 55 mo in patients with a solid VTT (p VTT was an independent predictor of CSS (p = 0.02). The power of our conclusion may be somewhat limited by the relatively small study population and the retrospective nature of the study. In patients with RCC and VTT, the presence of a friable thrombus is an independent predictor of CSS. If our finding is confirmed by further studies, the consistency of the tumour thrombus should be introduced into routine pathologic reports to provide better patient risk stratification.

  4. Human Renal Normal, Tumoral, and Cancer Stem Cells Express Membrane-Bound Interleukin-15 Isoforms Displaying Different Functions

    2015-06-01

    Full Text Available Intrarenal interleukin-15 (IL-15 participates to renal pathophysiology, but the role of its different membrane-bound isoforms remains to be elucidated. In this study, we reassess the biology of membrane-bound IL-15 (mb-IL-15 isoforms by comparing primary cultures of human renal proximal tubular epithelial cells (RPTEC to peritumoral (ptumTEC, tumoral (RCC, and cancer stem cells (CSC/CD105+. RPTEC express a 14 to 16 kDa mb-IL-15, whose existence has been assumed but never formally demonstrated and likely represents the isoform anchored at the cell membrane through the IL-15 receptor α (IL-15Rα chain, because it is sensitive to acidic treatment and is not competent to deliver a reverse signal. By contrast, ptumTEC, RCC, and CSC express a novel N-hyperglycosylated, short-lived transmembrane mb-IL-15 (tmb-IL-15 isoform around 27 kDa, resistant to acidic shock, delivering a reverse signal in response to its soluble receptor (sIL-15Rα. This reverse signal triggers the down-regulation of the tumor suppressor gene E-cadherin in ptumTEC and RCC but not in CSC/CD105+, where it promotes survival. Indeed, through the AKT pathway, tmb-IL-15 protects CSC/CD105+ from non-programmed cell death induced by serum starvation. Finally, both mb-IL-15 and tmb-IL-15 are sensitive to metalloproteases, and the cleaved tmb-IL-15 (25 kDa displays a powerful anti-apoptotic effect on human hematopoietic cells. Overall, our data indicate that both mb-IL-15 and tmb-IL-15 isoforms play a complex role in renal pathophysiology downregulating E-cadherin and favoring cell survival. Moreover, “apparently normal” ptumTEC cells, sharing different properties with RCC, could contribute to organize an enlarged peritumoral “preneoplastic” environment committed to favor tumor progression.

    Combined radiochemotherapy (RCT) for gastric cancer with three-dimensional conformal radiotherapy (3D-CRT) results in ablative doses to the upper left kidney, while image-guided intensity-modulated radiotherapy (IG-IMRT) allows kidney sparing despite improved target coverage. Renal function in long-term gastric cancer survivors was evaluated with 3T functional magnetic resonance imaging (MRI) including diffusion-weighted imaging (DWI) and {sup 23}Na imaging. Five healthy volunteers and 13 patients after radiotherapy were included: 11 x IG-IMRT; 1 x 3D-CRT; 1 x ''positive control'' with stereotactic body radiotherapy (SBRT) of a metastasis between the spleen/left kidney. Radiation doses were documented for the upper/middle/lower kidney subvolumes. Late toxicity was evaluated based on CTC criteria, questionnaire, and creatinine values. Morphological sequences, DWI images, and {sup 23}Na images were acquired using a {sup 1}H/{sup 23}Na-tuned body-coil before/after intravenous water load (WL). Statistics for [{sup 23}Na] (concentration) and apparent diffusion coefficient (ADC) values were calculated for upper/middle/lower renal subvolumes. Corticomedullary [{sup 23}Na] gradients and [{sup 23}Na] differences after WL were determined. No major morphological alteration was detected in any patient. Minor scars were observed in the cranial subvolume of the left kidney of the 3D-CRT and the whole kidney of the control SBRT patient. All participants presented a corticomedullary [{sup 23}Na] gradient. After WL, a significant physiological [{sup 23}Na] gradient decrease (p < 0.001) was observed in all HV and IG-IMRT patients. In the cranial left kidney of the 3D-CRT patient and the positive control SBRT patient, the decrease was nonsignificant (p = 0.01, p = 0.02). ADC values were altered nonsignificantly in all renal subvolumes (all participants). Renal subvolumes with doses ≥ 35 Gy showed a reduced change of the [{sup 23}Na] gradient after WL (p = 0

    In some patients with light chain deposition disease (LCDD) there is also evidence of myeloma cast nephropathy (MCN) on renal biopsy. The purpose of this study was to evaluate the renal and survival outcome of patients with concomitant diagnosis of MCN and LCDD to LCDD and MCN alone. Eighty seven patients were identified and divided into LCDD (n=45), MCN (n=29), and LCDD+ MCN (n=13). Patients with LCDD+ MCN had a worse overall survival (OS) compared to patients with LCDD (p=0.03), but similar to patients with MCN (p=0.4). Death-censored renal survival was no different amongst the groups. Presenting with acute renal failure at time of renal biopsy (HR 7.2, p=0.0002) was an independent poor renal prognostic factor while older age (HR 1.06, p=0.0002), presence of osteolytic lesions (HR 4.4, p<0.0001), and requirement for dialysis or creatinine≥5 mg/dL (HR 3.2, p=0.0006) at time of renal biopsy were independent poor prognostic factors for OS.

O sucesso no tratamento conservador dos pacientes com trauma renal depende de um acurado estadiamento da extensão da lesão, classificado de acordo com a Organ Injury Scaling do Colégio Americano de Cirurgiões. O tratamento conservador não-operatório é seguro e consiste de observação contínua, repouso no leito, hidratação endovenosa adequada e antibioti- coterapia profilática, evitando-se uma exploração cirúrgica desnecessária e possível perda renal. As indicações para exploração cirúrgica imediata são abdome agudo, rápida queda do hematócrito ou lesões associadas determinadas na avaliação radiológica. Quando indicada, a exploração renal após controle vascular prévio é segura, permitindo cuidadosa inspeção do rim e sua reconstrução com sucesso, reduzindo a probabilidade de nefrectomia.We present a revision of the renal trauma with emphasis in the radiographic evaluation, particularly CT scan that it has largely replaced the excretory urogram and arteriogram in the diagnostic worh-up and management of the patient with renal trauma.

However, immunotherapy appears to be effective in 15—20% of cases, with interleukin-2 becoming the standard therapy for this disease. As a consequence of the immune susceptibility of RCC, other avenues of immunotherapy are being explored, such as nonmyeloablative allogeneic stem cell transplantation (NST. A number of trials have shown NST to be effective in varying degrees, causing partial or complete regression. Although nonmyeloablative conditioning is safer than myeloablative conditioning, its role has yet to be clearly proven as many studies have shown variable effect. Alongside this limitation, transplant-related toxicity also forms obstacles. Regardless of the limitation of NST, further refinement of the technique, with appropriate patient selection, may lead to this being an effective therapeutic choice for a significant number of individuals.

    University Medical Center (1998-2012) were classified as clear-cell, papillary, chromophobe and other subtypes. In pairwise comparisons, we used multivariate logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between race, sex, age, end-stage renal...... disease (ESRD) and body mass index at diagnosis according to histological subtype. RESULTS: The RCC subtype distribution was significantly different in black people from that in white people (P people than white...... people (35.7 vs 13.8%). In multivariate analyses, compared with clear-cell RCC, people with papillary RCC were significantly more likely to be black (OR 4.15; 95% CI 2.64-6.52) and less likely to be female (OR 0.60; 95% CI 0.43-0.83). People with chromophobe RCC were significantly more likely...

    为了探讨食管癌术后急性肾衰竭发生的原因及防治经验,回顾性分析13例术后发生急性肾衰竭食管癌患者的临床资料,并总结防治体会.结果显示患者平均年龄67.5岁,体重50.4千克,皆有严重的吞咽梗阻症状,其中8例术前发现低蛋白血症,3例术前有不同程度的肾功能不全;术后3天内出现急性肾衰竭,治疗纠正肾前性病因、利尿和改善肾血流灌注等,其中4例结合血液净化;10例治愈,3例好转自动出院.就此得出结论食管癌患者术前低容量且营养不良状态是术后急性肾衰竭的重要原因;治疗注意纠正肾前性因素和改善肾灌注,必要时结合血液净化治疗,有助于防治食管癌术后急性肾功能衰竭.%To investigate the causes and experience of treatment for acute renal failure following the surgery for esophageal cancer, the clinical data of 13 patients with acute renal failure after surgery for esophageal cancer were retrospectively reviewed. The average age of patients was 67.5, and the mean weight was 50.4 kg. All patients had severe obstructive symptom, 8 of 13 patients with hypoproteinemia and 3 of 13 patients with renal dysfunction were detected preoperatively.Acute renal failure was followed in three days after operation. Treatment included correction of possible prerenal causes,diuretic drugs and improvement of renal perfusion and so on. Four of 13 patients underwent blood purification. Ten cases were cured and 3 cases improved markedly and were discharged. The conclusions include that hypovolemia and malnutrition are the important causes of acute renal failure following the surgery for esophageal cancer, and correction of possible prerenal causes, improvement of renal perfusion and adequate blood purification can contribute to its treatment.

    Bacillus Calmette-Guèrin (BCG) is commonly used not only as an infant vaccination, but also as a treatment of and prophylaxis to prevent recurrence in the management of non-muscle-invasive bladder cancer. However, the use of "live" BCG is sometimes complicated by associated infection. We present a case study of a 77-year-old man who developed bilateral renal masses after intravesical BCG therapy was initiated in November 2013, following transurethral resection of non-muscle-invasive bladder cancer. After four courses of BCG (Japan strain, 80 mg per treatment) instillations, a computed tomography examination for febrile episodes showed multiple bilateral renal masses, accompanied by a histological finding of a granulomatous reaction. An acid fast bacterium was cultured from only urine among blood, urine, and microscopic samples. Using the cultured strain, BCG infection was confirmed by the specific gene deletion pattern based on allele-specific polymerase chain reaction analysis. Anti-tuberculosis treatment, including isoniazid (300 mg/day), rifampicin (600 mg/day), and ethambutol (1,000 mg/day), was started for the BCG-related renal granuloma in February 2014. After 3 months, antibiotic therapy was discontinued owing to severe appetite loss, though the masses remained solid. No rapid growth has been detected after anti-BCG therapy. Intravesical BCG therapy is recommended worldwide as one of standard treatments for non-muscle-invasive bladder cancer. We should closely observe patients undergoing this approach for emerging BCG complications.
