RESUMO

BACKGROUND: Practice guidelines hardly recommend herbal extracts for male lower urinary tract symptoms (LUTS). However, many patients are unsatisfied with first-line synthetic drugs and often prefer herbal medicines because of good tolerability. To improve the decision-making process, which should consider the patients' expectations, it is crucial to reflect on the role of phytotherapy in the treatment of LUTS. We (panel experts) reflected on current guideline recommendations and real practice across various European countries and debated the potential role of plant extracts with a focus on pumpkin seed soft extract investigated over 12 months in two randomised placebo-controlled trials. SUMMARY: Most guidelines give no clear recommendations on phytotherapy due to the heterogeneity of clinically investigated extracts. Nevertheless, plant extracts are prescribed to patients with mild-to-moderate LUTS. Also, self-medicating patients often handle their complaints with herbal products. Many patients aim to avoid synthetic drugs for fear of sexual functional side effects and a negative impact on their quality of life. For the elderly, vasoactive comedications might become an issue. When taking plant extracts, patients experience an acceptable symptomatic relief similar to that achieved with synthetics but without side effects. Key Messages: In shared decision-making for purely symptomatic treatment, a low risk of side effects takes priority. We propose to consider patient preferences in the treatment of mild-to-moderate LUTS in men with a low risk of disease progression. We found a consensus that pumpkin seed soft extract adds to the therapeutic armamentarium for patients who cannot or do not want to apply synthetic drugs.

RESUMO

AIM: To retrospectively analyze patients treated by renal tumor and venous tumor thrombus (VVT) removal and to introduce a less stressful and safer surgical method without thoracotomy in Neves level 3 cases. METHODS: From 2002 to 2011, 33 patients underwent surgery for renal cell cancer combined with tumor thrombus of the inferior vena cava. Preoperative symptoms, tumor-node-metastasis classification of tumors, thrombus extension classified by Neves and Zincke system, types of surgical interventions, complications, postoperative management, and survival results were analyzed. RESULTS: Ten patients had level 1, 17 had level 2, and 6 had level 3 thrombi according to Neves and Zincke. In 5 patients with level 3 thrombi, the liver was mobilized without thoracotomy and in 1 patient endoluminal occlusion was utilized. There was no intraoperative mortality. The median survival time of 10 patients who died during follow-up period was 36.6 months (range, 0-121 months). CONCLUSION: Renal cell cancer complicated with tumor thrombus without metastasis can be curable by performing a complete resection. The thrombus level determines the surgical approach and method. Our results confirm that level 3 caval vein tumor thrombus can be safely surgically treated by laparotomy with liver mobilization. Thoracotomy, use of cardiopulmonal bypass, and hypothermic circulatory arrest can be avoided with adequate liver- and vascular surgery methods.

RESUMO

The primary testicular non-Hodgkin lymphoma, which has been first described in 1866, is a very uncommon type of urological neoplasia occuring mostly in the elderly ages. It only gives 5% of the testicular tumors, 2% of extranodal lymphomas, and barely 1% of all non-Hodgkin diseases. Patients with testicular non-Hodgkin lymphomas need prompt multidisciplinary aid because without treatment the outcome can be unfavorable. The authors discuss the attributes, diagnostic modalities and treatment options of the primary testicular non-Hodgkin lymphoma and present a case of a 68-year-old patient who underwent orchiectomy, chemo- and radiotherapy after having been diagnosed with the tumor. The follow-up PET-CT and cerebrospinal fluid analysis found no further sign of the disease, and complete remission has been achieved.

RESUMO

Endostatin, the proteolytic fragment of collagen XVIII, is an inhibitor of angiogenesis and tumor growth. Interestingly, elevated circulating endostatin levels have been found to correlate with poor patients' prognosis in several cancers. The aim of this study was to assess the prognostic value of endostatin in bladder cancer (BC) and to gain insight into the mechanisms involved in its production. This retrospective study included a total of 337 patients with BC and 103 controls. Collagen XVIII gene expression was analyzed using real-time PCR (n = 82). Endostatin tissue localization was assessed by immunohistochemistry (n = 27). Endostatin serum (n = 87) and urine (n = 153) levels were determined by ELISA. In 12 cases, both serum and paraffinized tissue samples from the same patients were available. We found decreased collagen XVIII tissue expression and increased endostatin urine and serum concentration in samples of patients with BC compared to controls. High serum endostatin levels correlated with the presence of lymph node metastases and MMP-7 concentrations and were independently associated with poor metastasis-free and disease-specific survival. Immunohistochemical analysis revealed a strong endostatin staining in the wall of tumor associated blood vessels in superficial but not in muscle-invasive BCs. Based on these, we concluded that elevated endostatin levels in patients with BC are the consequence of enhanced extracellular matrix degradation and are independent from collagen XVIII expression. Furthermore, serum endostatin levels may provide prognostic information independent from histopathological parameters and may therefore help to optimize therapy decisions. Loss of endostatin expression in tumor associated blood vessels might represent an important step supporting tumor-induced angiogenesis.

RESUMO

UNLABELLED: What's known on the subject? and What does the study add? Insulin-like growth factor mRNA-binding protein 3 (IMP3) is an oncofetal protein found to be re-expressed in a series of human cancers including bladder cancer. In vitro analyses showed an invasion and proliferation promoting effect for IMP3. Further in vitro studies suggested that IMP3 is able to bind to the mRNAs of CD44 and insulin-like growth factor 2 (IGF2), enhancing their stability and expression. However, this molecular interaction has not yet been analysed in tumour samples. In the present study, we identified for the first time high IMP3 tissue protein expression as an independent predictor of poor patients' survival in muscle-invasive bladder cancer. Furthermore, there was no correlation between IMP3 and its molecular targets in bladder carcinoma specimens and concluded that the tumour-promoting effect of IMP3 is not related to its regulatory action on IGF2 and CD44. OBJECTIVE: To assess the prognostic value and molecular actions of the oncofetal protein insulin-like growth factor mRNA-binding protein 3 (IMP3) in muscle-invasive bladder cancer (BC). PATIENTS AND METHODS: IMP3 expression was analysed by immunohistochemistry, real-time polymerase chain reaction and Western blot analysis in 224 patients with BC. The molecular targets of IMP3; CD44, insulin-like growth factor 2 (IGF2) and its receptor the IGF1 receptor (IGF1-R) were also investigated. Expression levels were correlated with clinical follow-up data by using both univariate and multivariate Cox regression analyses. RESULTS: IMP3 mRNA and protein levels were significantly elevated in high-stage and high-grade muscle-invasive BC. In muscle-invasive BC IMP3 protein but not gene expression proved to be an independent predictor of disease-specific (hazard ratio [HR] 2.58, 95% confidence interval [CI] 1.28-4.56, P = 0.004) and overall survival (HR 2.07, 95% CI 1.12-3.82, P = 0.020). The expression levels of IGF2 and CD44 showed no correlation with that of IMP3. CONCLUSIONS: High IMP3 protein levels may identify patients with BC at high risk of disease progression and may therefore select patients for a more intensive therapy or for a strict follow-up. Its high expression in high-grade bladder carcinoma cells makes IMP3 for an attractive target for therapy. The tumour promoting effect of IMP3 is independent from its regulatory action on IGF2 and CD44 expression.

RESUMO

Currently, twelve validated genetic variants have been identified that are associated with urinary bladder cancer (UBC) risk. However, those validated variants explain only 5-10% of the overall inherited risk. In addition, there are more than 100 published polymorphisms still awaiting validation or disproval. A particularly promising of the latter unconfirmed polymorphisms is rs2854744 that recently has been published to be associated with UBC risk. The [A] allele of rs2854744 has been reported to be associated with a higher promoter activity of the insulin-like growth factor-binding protein-3 (IGFBP3) gene, which may lead to increased IGFBP-3 plasma levels and cancer risk. Therefore, we investigated the association of rs2854744 with UBC in the IfADo case-control series consisting of 1,450 cases and 1,725 controls from Germany, Hungary, Venezuela and Pakistan. No significant association of rs2854744 with UBC risk was obtained (all study groups combined: unadjusted P = 0.4446; adjusted for age, gender and smoking habits P = 0.6510), besides a small effect of the [A] allele in the Pakistani study group opposed to the original findings (unadjusted P = 0.0508, odds ratio (OR) = 1.43 for the multiplicative model) that diminished after adjustment for age, gender and smoking habits (P = 0.7871; OR = 0.93). Associations of rs2854744 with occupational exposure to urinary bladder carcinogens and smoking habits were also not present. A meta-analysis of all available case-control series including the original discovery study resulted in an OR of 1.00 (P = 0.9562). In conclusion, we could not confirm the recently published hypothesis that rs2854744 in the IGFBP3 gene is associated with UBC risk.

RESUMO

Recently, rs11892031[A] has been identified in a genome-wide association study (GWAS) to confer increased risk of urinary bladder cancer (UBC). To confirm this association and additionally study a possible relevance of exposure to urinary bladder carcinogens, we investigated the IfADo UBC study group, consisting of eight case-control series from different regions including 1,805 cases and 2,141 controls. This analysis was supplemented by a meta-analysis of all published data, including 13,395 cases and 54,876 controls. Rs11892031 A/A was significantly associated with UBC risk in the IfADo case-control series adjusted to cigarette smoking, gender, age and ethnicity (OR = 1.18; 95% CI = 1.02-1.37; P = 0.026). In the meta-analysis, a convincing association with UBC risk was obtained (OR = 1.19; 95% Cl = 1.12-1.26; P < 0.0001). Interestingly, the highest odds ratios were obtained for individual case-control series with a high degree of occupational exposure to polycyclic aromatic hydrocarbons and aromatic amines: cases with suspected occupational UBC (OR = 1.41) and cases from the highly industrialized Ruhr area (OR = 1.98) compared with Ruhr area controls (all combined OR = 1.46). Odds ratios were lower for study groups with no or a lower degree of occupational exposure to bladder carcinogens, such as the Hungary (OR = 1.02) or the ongoing West German case-control series (OR = 1.06). However, the possible association of rs11892031[A] with exposure to bladder carcinogens still should be interpreted with caution, because in contrast to the differences between the individual study groups, interview-based data on occupational exposure were not significantly associated with rs11892031. In conclusion, the association of rs11892031[A] with UBC risk could be confirmed in independent study groups.

RESUMO

Elevated matrix metalloproteinase-7 (MMP-7) tissue expression and serum concentration have been shown to be associated with cancer progression and metastasis. The aim of our study was to assess the prognostic value of preoperative circulating MMP-7 levels in serum samples of patients with clinically localized prostate cancer. Furthermore, we compared the serum MMP-7 levels between patients with organ confined and metastatic prostate cancer. MMP-7 levels were measured in 93 patients with localized prostate cancer, 13 patients with distant bone metastasis and in sera of 19 controls using enzyme-linked immunosorbent assay. The results were compared to the clinical follow-up data. We did not find any significant difference in MMP-7 serum levels between patients and controls (p = 0.268). Circulating MMP-7 serum concentration was significantly elevated in patients with distant metastasis (p < 0.001). For the detection of distant prostate cancer metastasis, using a cut-off value of 3.7 ng/ml, a specificity of 69% and a sensitivity of 92% were observed. Multivariate analysis identified high MMP-7 serum concentration as an independent risk factor for prostate cancer-related death both in a preoperative and a postoperative model (p = 0.003 and 0.018, respectively). Furthermore, the evaluation of predictive models revealed that addition of serum MMP-7 levels to the preoperatively available predictors improves prognostic accuracy (the concordance index increased from 0.631 to 0.734 when MMP-7 was included). Based on these, we concluded that MMP-7 is a potential marker to identify patients with metastatic prostate cancer. In clinically localized prostate cancer, MMP-7 may provide independent prognostic information, thereby helping to optimize therapy decisions.

RESUMO

Genotyping N-acetyltransferase 2 (NAT2) is of high relevance for individualized dosing of antituberculosis drugs and bladder cancer epidemiology. In this study we compared a recently published tagging single nucleotide polymorphism (SNP) (rs1495741) to the conventional 7-SNP genotype (G191A, C282T, T341C, C481T, G590A, A803G and G857A haplotype pairs) and systematically analysed if novel SNP combinations outperform the latter. For this purpose, we studied 3177 individuals by PCR and phenotyped 344 individuals by the caffeine test. Although the tagSNP and the 7-SNP genotype showed a high degree of correlation (R=0.933, P<0.0001) the 7-SNP genotype nevertheless outperformed the tagging SNP with respect to specificity (1.0 vs. 0.9444, P=0.0065). Considering all possible SNP combinations in a receiver operating characteristic analysis we identified a 2-SNP genotype (C282T, T341C) that outperformed the tagging SNP and was equivalent to the 7-SNP genotype. The 2-SNP genotype predicted the correct phenotype with a sensitivity of 0.8643 and a specificity of 1.0. In addition, it predicted the 7-SNP genotype with sensitivity and specificity of 0.9993 and 0.9880, respectively. The prediction of the NAT2 genotype by the 2-SNP genotype performed similar in populations of Caucasian, Venezuelan and Pakistani background. A 2-SNP genotype predicts NAT2 phenotypes with similar sensitivity and specificity as the conventional 7-SNP genotype. This procedure represents a facilitation in individualized dosing of NAT2 substrates without losing sensitivity or specificity.

RESUMO

OBJECTIVE: • To assess the presence of matrix metalloproteinase (MMP)-7 in urine samples of patients with bladder cancer and to investigate the correlation between MMP-7 urine concentration and clinicopathological variables. PATIENTS AND METHODS: • The presence of MMP-7 in the urine of patients with bladder cancer was tested in 32 representative cases using immunoprecipitation followed by western blot analysis. • Urinary MMP-7 concentration levels were analyzed in 132 patients with bladder cancer and 96 controls using an enzyme-linked immunosorbent assay. RESULTS: • MMP-7 levels did not differ significantly between patients with localized bladder cancer and controls (P= 0.174). On the other hand, we detected a fourfold, significantly elevated MMP-7 concentration in urine samples of patients with bladder cancer with regional or distant metastasis (P= 0.003). • Using a threshold value of 6.88 ng/ml, determined by receiver-operating characteristic curve analysis, a specificity of 82% and a sensitivity of 78% were observed. • Western blot analysis revealed that the 55-kDa tissue inhibitor of metalloproteinase 1 complexed MMP-7 is the dominant form of urinary matrilysin. CONCLUSIONS: • MMP-7 is present in detectable amounts in the urine of patients with bladder cancer. Its concentrations are significantly elevated in patients with metastatic disease. • Determination of urinary matrilysin level could help to detect bladder cancer metastasis, and may therefore provide a more reliable prognosis and influence therapy decisions.

RESUMO

INTRODUCTION: Hypospadias is the most common penis malformation, and there exist a variety of surgical approaches used to correct the abnormal position of the meatus. Although the long-term outcomes of surgery are considered important for psychosexual development, only a few attempts have been made to evaluate patient satisfaction. AIM: The aim of our study was to evaluate surgical results and psychosocial adaptations in a homogeneous group of subjects with severe penile hypospadias who underwent the same types of surgical repairs during childhood and compare the results to data obtained from age-matched healthy controls. METHODS: In this cross-sectional study, 104 men (between 24 and 42 years old) who underwent an uncomplicated two-stage hypospadias repair in their childhood and 63 age-matched healthy men without genital malformations completed the questionnaire. MAIN OUTCOME MEASURES: Difference in self-perception assessed by a 15-item questionnaire regarding psychosexual well-being and penile appearance between subjects with corrected hypospadias and healthy participants. RESULTS: On average, subjects with a hypospadias repair were less satisfied with their genital appearance; however, they were more satisfied with their sex lives compared to healthy controls. The meatus distance was approximately 1.5 cm from the tip of the penis after surgical correction. None of the postoperative surgical results correlated with patient satisfaction. Furthermore, the small percentage of patients (11%) who were very unsatisfied with their surgical outcomes had no significant differences in surgical outcomes compared to satisfied patients. However, there was a significant difference between the two groups in almost all psychological outcome measures. CONCLUSIONS: In adults who underwent an uncomplicated ventral repair of a severe penile hypospadias 20-30 years earlier, healthy psychosexual development was achieved despite the lack of a glanular meatus. Early identification of unsatisfied patients is important for appropriate long-term follow-up and counseling.

RESUMO

INTRODUCTION: Prostate cancer is the second leading cause of cancer death among men in developed countries. Estrogen receptor-alpha (ER-α), vitamin D receptor (VDR), and the calcium-sensing receptor (CaSR), partly through their effects on calcium levels are implicated in the proliferation and carcinogenesis in the prostate gland. VDR, ER-α and CaSR genes show polymorphisms in humans that appear to have clinical significance in many pathological conditions, such as prostate cancer. Our aim was to evaluate the role of ER-α (PvuII, XbaI), VDR (BsmI) and CaSR (A986S) gene polymorphisms and serum calcium levels in the pathogenesis of prostate cancer. MATERIAL AND METHODS: Two hundred four patients with prostate cancer and 102 healthy controls were recruited into a hospital-based case control study. After genotyping, the relationship between the individual genotypes and prostate cancer was investigated. RESULTS: Both the ER-α XbaI and the VDR BsmI polymorphisms were significantly related to the risk of prostate cancer. An age adjusted logistic regression limited to controls and patients not receiving bisphosphonate therapy showed that higher corrected serum calcium and the VDR Bb/BB genotypes independently increased the risk of prostate cancer. CONCLUSIONS: ER-α XbaI and VDR BsmI genetic polymorphisms had a significant association with the risk of prostate cancer. Both VDR BsmI genotypes and serum calcium levels were independently related to the risk of prostate cancer, suggesting an influence of VDR on the development of this malignancy.

RESUMO

OBJECTIVE: To investigate the safety and efficacy of a special terpene combination in the treatment of patients with urolithiasis after extracorporeal shockwave lithotripsy (ESWL). PATIENTS AND METHODS: 222 patients with clinically stable kidney or ureter stones of 0.3-2.0 cm undergoing complication-free ESWL were randomised to receive a special terpene combination (Rowatinex®; 3 × 2 capsules/day) or placebo. The study consisted of a 12-week active treatment phase and a 2-week follow-up phase. All patients had a physical examination, and diagnosis of kidney stones was made by X-ray, intravenous pyelogram or ultrasound at weeks 1, 4, 8 and 12 as well as after 2 weeks of follow-up. Stone-free status was defined as obviously successful expulsion of calculi/fragments, being without any stone. RESULTS: In all, when compared to placebo, significantly more patients receiving the terpene combination treatment in the intent-to-treat (ITT) group [72 (67.9%) vs. 49 (50.0%); p = 0.0009] and the per-protocol (PP) group [69 (78.4%) vs. 48 (52.2%); p = 0.0004] were stone-free at the end of the study. Treatment with the terpene combination was also more effective when analysed with respect to the size of the treated stone. In addition, treatment with the terpene combination significantly reduced the median time to stone-free status from 85.0 to 56.0 days (p = 0.0061) and from 85.0 to 49.5 days (p = 0.0028) in the ITT and PP populations, respectively. Nine mild-to-moderate adverse events (AE; terpene combination group: 7 AE in 4 patients; placebo group: 2 AE in 2 patients) were assessed as drug-related. CONCLUSIONS: Treatment with the terpene combination is well tolerated and safe. The terpene combination was found to be an efficacious treatment in eliminating calculi fragments generated by ESWL as compared to placebo. The pharmacodynamic properties of the terpene combination (antilithogenic, antibacterial, antiinflammatory, spasmolytic and analgesic effects), which have been also confirmed in preclinical studies, represent a valuable alternative to the different drugs used in the treatment of urolithiasis.

RESUMO

AIM: Follow-up and review of patients who underwent surgery for renal cell cancer combined with tumor thrombus of the inferior vena cava at the Department of Urology Semmelweis University, Budapest, Hungary. MATERIAL AND METHODS: From l998 to 2010 twenty one patients underwent surgery for renal cell cancer combined with tumor thrombus of the inferior caval vein. Preoperative symptoms, TNM classification of the tumors, types of surgical interventions, complications, postoperative management and survival results were involved in the analysis. Mean follow-up period was 39 months, ranging from 3 to 101 months. RESULTS: In five cases of level 3 thrombi the liver was mobilized without thoracotomy, and endoluminar occlusion was applied in one case. Intraoperative mortality was 9,5%. Survival time of patients with distant metastases was 12.1 months (3-9). Three patients without metastases died in the follow up period, their survival time was 26.7 months ranging from 22 to 31 months. Eight patients (73%) were alive at the time of the last follow-up. The mean survival time was 5.6 years ranging from 39 to 101 months. CONCLUSION: Our results support that level 3 caval vein tumor thrombus can be removed by less aggressive surgical approach and underline the benefit of the surgical intervention without thoracotomy.

RESUMO

Matrix metalloproteinases (MMPs) play an important role in tumor progression and metastasis. Here, we investigated the prognostic relevance of MMP-7 in urinary bladder cancer. MMP-7 gene expression was measured in tissue samples of 101 patients using quantitative real-time PCR. Circulating MMP-7 serum levels of 98 individuals (79 patients and 19 controls) were analyzed by enzyme-linked immunosorbent assay. The results were compared with the clinical follow-up data, performing Kaplan-Meier log-rank test as well as univariate and multivariate Cox analysis. In representative cases, immunohistochemical analysis for MMP-7 was performed. We detected significantly elevated MMP-7 levels both in tissue and serum samples of patients with metastatic disease (P = 0.001 and P = 0.002). Multivariate analysis revealed that high MMP-7 tissue expression and serum concentration are stage- and grade-independent predictors of both metastasis-free (hazard ratio [HR] = 3.80, 95% confidence interval [CI], 1.29-11.23, P = 0.016, and HR = 2.53, 95% CI, 1.01-6.37, P = 0.048) and disease-specific survival (HR = 1.89, 95% CI, 1.00-3.55, P = 0.050 and HR = 1.95, 95% CI, 1.03-3.71, P = 0.041). Based on these findings, we conclude that MMP-7 is a promising marker to detect present and to predict future metastasis. Serum MMP-7 analysis provides information about the risk of metastasis before surgery which could help to optimize therapeutic procedures. Furthermore, high MMP-7 tissue and/or serum levels could identify patients most likely to benefit from early adjuvant chemotherapy.

RESUMO

INTRODUCTION: While adjuvant immunotherapy with Bacille Calmette Guérin (BCG) is effective in non-muscle-invasive bladder cancer (BC), adverse events (AEs) are considerable. Monocyte-derived activated killer cells (MAK) are discussed as essential in antitumoural immunoresponse, but their application may imply risks. The present trial compared autologous intravesical macrophage cell therapy (BEXIDEM) to BCG in patients after transurethral resection (TURB) of BC. MATERIALS AND METHODS: This open-label trial included 137 eligible patients with TaG1-3, T1G1-2 plurifocal or unifocal tumours and >or=2 occurrences within 24 months and was conducted from June 2004 to March 2007. Median follow-up for patients without recurrence was 12 months. Patients were randomized to BCG or mononuclear cells collected by apheresis after ex vivo cell processing and activation (BEXIDEM). Either arm treatment consisted of 6 weekly instillations and 2 cycles of 3 weekly instillations at months 3 and 6. Toxicity profile (primary endpoint) and prophylactic effects (secondary endpoint) were assessed. RESULTS: Patient characteristics were evenly distributed. Of 73 treated with BCG and 64 with BEXIDEM, 85% vs. 45% experienced AEs and 26% vs. 14% serious AEs (SAE), respectively (p<0.001). Recurrence occurred significantly less frequent with BCG than with BEXIDEM (12% vs. 38%; p<0.001). DISCUSSION: This initial report of autologous intravesical macrophage cell therapy in BC demonstrates BEXIDEM treatment to be safe. Recurrence rates were significantly lower with BCG however. As the efficacy of BEXIDEM remains uncertain, further data, e.g. marker lesions studies, are warranted. TRIAL REGISTRATION: The trial has been registered in the ISRCTN registry http://isrctn.org under the registration number ISRCTN35881130.

RESUMO

OBJECTIVE: To investigate the patterns of expression of the junctional proteins beta-catenin and claudins in different prognostic groups of patients with prostatic cancer, to determine their value as prognostic markers. PATIENTS AND METHODS: We evaluated the samples of 30 patients who had a radical prostatectomy for organ-confined cancer (pT2N0M0), men with clinically advanced cancer, and a control group with benign prostatic hyperplasia. Using immunohistochemistry applied to tissue microarrays, each group was evaluated for claudin-1, -2, -3, -4, -5, -7, -8 and -10, and beta-catenin expression. RESULTS: There were differences among the three groups in the expression of claudin-1 (P = 0.001), -2 (P = 0.014), -3 (P = 0.027), -4 (P = 0.001), -8 (P = 0.001) and beta-catenin (P = 0.002), regardless of Gleason score. By contrast, claudin-5, -7 and -10 patterns were not significantly different among the groups. Furthermore, claudin-1 (P = 0.014) and -4 (P = 0.004) could be used to distinguish between those patients who had metastases and those who did not. CONCLUSIONS: The pattern of claudin expression could be a novel diagnostic marker in re-classifying adenocarcinomas, and an additional sensitive predictive factor for a clinically poor prognosis. Our results suggest that patients with organ-confined and advanced cancer are subsets with distinct claudin expression profiles, and that claudin-4 is related to cellular differentiation in prostate cancer, which is not only the receptor molecule for the Clostridium perfringens enterotoxin, and thus a theoretical future therapeutic target for prostate cancer, but also a marker of progression.

RESUMO

Single nucleotide polymorphism (SNP) rs710521[A], located near TP63 on chromosome 3q28, was identified to be significantly associated with increased bladder cancer risk. To investigate the association of rs710521[A] and bladder cancer by new data and by meta-analysis including all published data, rs710521 was studied in 1,425 bladder cancer cases and 1,740 controls that had not been included in previous studies. Blood samples were collected from 1995 to 2010 in Germany (n = 948/1,258), Hungary (n = 262/65), Venezuela (n = 112/190) and Pakistan (n = 103/227) supplemented by a meta-analysis of 5,695 cases and 40,187 controls. Detection of a A/G substitution (rs710521) on chromosome 3q28, position 191128627 was done via fast real-time polymerase chain reaction (rt-PCR). Rs710521[A] is associated with increased risk in the unadjusted analysis (OR = 1.21; 95% Cl = 1.04-1.40; P = 0.011) and in the recessive model adjusted for age, gender, smoking habits and ethnicity (OR = 1.23; 95% Cl = 1.05-1.44; P = 0.010). No difference between individuals occupationally exposed versus not occupationally exposed to urinary bladder carcinogens was observed concerning the relevance of rs710521[A]. Similarly, rs710521[A] did not confer different susceptibility in smokers and non-smokers. Performing a meta-analysis of 5,695 cases and 40,187 controls including all published studies on rs710521, a convincing association with bladder cancer risk was obtained (OR = 1.18; 95% Cl = 1.12-1.25; P < 0.0001). However, the odds ratio is relatively small.

RESUMO

CASE REPORT: A renal cell cancer patient with late onset of multiorgan metastases showed an unusually long survival following surgical resection. Femoral metastasis appeared 11 years, and contra lateral kidney and adrenal gland metastasis 19 years after the primary nephrectomy, respectively. Following the resection of the femur and implantation of endoprosthesis and removal of adrenal gland and partial nephrectomy, the patient was disease-free 20 years after the first diagnosis of cancer. CONCLUSION: The long survival and successful treatment underline the importance and efficiency of radical metastasectomy even in the case of late onset multiorgan metastases of renal cell cancer. The life expectancies are better in the late onset of bone metastasis following the nephrectomy. The very late onset of metastases in this case shows however the importance of lifelong follow up.
