  • Objective: To evaluate the association between tea consumption and the risk of renal cell carcinoma. Methods: We searched PubMed, Web of Science and Scopus between 1970 and November 2012. Two evaluators independently reviewed and selected articles based on predetermined selection criteria. Results: Twelve epidemiological studies (ten case-control studies and two cohort studies) were included in the final analysis. In a meta-analysis of all included studies, when compared with the lowest level of tea consumption, the overall relative risk (RR) of renal cell carcinoma for the highest level of tea consumption was 1.03 (95% confidence interval [CI] 0.89-1.21). In subgroup meta-analyses by study design, there was no significant association between tea consumption and renal cell carcinoma risk in ten case-control studies using adjusted data (RR=1.08, 95% CI 0.84-1.40). Furthermore, there was no significant association in two cohort studies using adjusted data (RR=0.95, 95% CI 0.81-1.12). Conclusion: Our findings do not support the conclusion that tea consumption is related to decreased risk of renal cell carcinoma. Further prospective cohort studies are required.

  • Background: Factors predictive of survival have been identified in Western patients with metastatic clear cell renal cell carcinoma (mCCRCC) treated with sunitinib. Less is known, however, about factors predictive of survival in Japanese patients. This study evaluated factors prognostic of survival in Japanese patients with mCCRCC treated with first-line sunitinib. Materials and Methods: This retrospective study evaluated 46 consecutive Japanese mCCRCC patients treated with sunitinib as first line therapy. Clinical and biochemical markers associated with progression-free survival (PFS) were analyzed, with prognostic factors selected by uniand multivariate Cox regression analyses. Results: Univariate analysis showed that factors significantly associated with poor PFS included Memorial Sloan-Kettering Cancer Center poor risk scores, International Metastatic RCC Database Consortium poor risk and high (>0.5 mg/dl) serum C-reactive protein (CRP) concentrations (p<0.001 each). Multivariate analysis showed that high serum CRP was independently associated with poorer PFS (p=0.040). Six month disease control rate (complete response, partial response and stable disease) in response to sunitinib was significantly higher in patients with normal (${\leq}0.5mg/dl$) than elevated baseline CRP (p<0.001). Conclusions: CRP is a significant independent predictor of PFS for Japanese patients with mCCRCC treated with first-line sunitinib. Pretreatment CRP concentration may be a useful biomarker predicting response to sunitinib treatment.

  • Renal artery pseudoaneurysm after blunt renal trauma is an uncommon complication of delayed hemorrhage, and diagnostic difficulties are experienced due to its rarity. Delayed hemorrhage after renal trauma is a life-threatening complication. Angiography is considered the gold standard to diagnose a traumatic renal artery pseudoaneurysm. We report here a case of delayed bleeding from a renal artery pseudoaneurysm that was diagnosed at 17 days after the injury and that was managed successfully with selective renal artery embolization without medical complication.

  • Purpose: We compared subtypes of papillary renal cell carcinoma (pRCC; types 1 and 2) and clear cell renal cell carcinoma (ccRCC) in patients with T1-stage RCC to analyze the impact of the subtype on oncological outcomes. Materials and Methods: This paper reviewed 75 patients with pRCC and 252 patients with ccRCC at T1-stage from 1998-2012. Thus, we assessed the impact of subtype on oncologic outcomes among patients with T1-stage RCC. We used Kaplan-Meier analysis to estimate the overall survival and recurrence-free survival The median follow-up duration was 95 months (interquartile range, 75.4-119.3 months). Results: The 5-year recurrence-free survivals of pRCC and ccRCC were 95.4% and 97.6%, respectively. pRCC is worse than ccRCC in terms of recurrence-free survival (p=0.008) and there was no significant difference in the overall survival between pRCC and ccRCC (p=0.32). In addition, there was no significant statistical difference between type 1 pRCC and type 2 pRCC in terms of either recurrence-free survival (p=0.526) or overall survival (p=0.701). Age (hazard ratio [HR], 1.069; p<0.001) and recurrence (HR, 4.93; p<0.001) were predictors of overall survival. Only tumor size (HR, 1.071; p=0.004) was predictors in the case of cancer specific survival in the multivariate analysis. Conclusions: Among patients with T1-stage RCC, recurrence after surgery was more common in pRCC than ccRCC. The subtype of pRCC (types 1 and 2) had no impact on the recurrence-free survival or overall survival.

  • In this study we evaluated the frequency of fusion between TMPRSS2 and ETS family members (ERG, ETV1, ETV4) in prostate cancers in patients from northern China in order to explore differences in fusion rates among regions in northern and southern China, other parts of Asia, Europe, and North America. We examined 100 prostate cancer patients, diagnosed by means of prostate biopsy; fluorescence in situ hybridization (FISH) was used to detect the expression of TMPRSS2, ERG, ETV1 and ETV4 in cancer tissue. Differences in gene fusion rates among different ethnics groups were also analyzed. Of the 100 prostate cancer patients, 55 (55%) had the fusion gene. Among the patients with the fusion gene, 46 (83.6%) patients had the TMPRSS2:ERG fusion product, 8 (14.8%) patients had TMPRSS2:ETV1 fusion, 1 (1.6%) patient had TMPRSS2:ETV4.

  • Background: Relationships between smoking and bladder neoplasms, one of the common malignancies, are well-known. Different smoking-related malignancies may occur together. In this study, we evaluated the stage and grade of bladder neoplasms in patients also featuring lung or larynx cancer. Materials and Methods: From January 2006 to February 2012, patients who underwent surgery for bladder neoplasms in our clinic were screened retrospectively. In the evaluation, 5 patients had larynx cancer and 20 patients have lung cancer in addition, all having been smoking for a long time. The bladder tumor stage and grade were investigated in these 25 cases. Results: Mean age of patients was 66.8 (49-78). In the evaulation, all of 5 patients who had larnyx cancer also had high grade urothelial cancer. One had T2 urothelial, and 3 T1 urothelial cancer. In the same way, all of the 20 patients with lung cancer also have high grade urothelial cancer, three T2, and 13 T1. Bladder cancer stage and grade were determined to be significantly increased in patients with concomitant bladder and lung or larynx cancer. Conclusions: In the patients who have smoking releated second malignancy, bladder cancer prognosis appears more aggressive. We now need a larger series and multi-center studies for understanding relevant pathophysiology.

  • Background: Diabetes is a chronic disease characterized by impaired fasting blood glucose that leads to disturbances in various organs. In this study, we evaluated relationships between tumor size and grade in a population of diabetic and non-diabetic patients with renal cell carcinoma. Materials and Methods: Between 2007-2013, in our clinic radical nephrectomy performed to 310 patients for renal tumors and pathology reported renal cell carcinoma cases were enrolled in the study. Patients with and without a history of diabetes regarding fasting glucose and HgA1c levels were evaluated during surgery for tumor size and Fuhrman grade. Results: Diabetes was found in 95 patients. The mean age of the patients with and without diabetes mellitus was 64.3 (40-79) and 58.4 (31-87) years, respectively. In the diabetes group 51% of patients had a tumor size over 7 cm and 54% a tumor grade over Fuhrman 3. The respective figures in the non-diabetes group were 35% and 30% (p<0.05 in both cases). Conclusions: Renal cancer appears more aggressive in patients with diabetes. In this study lifestyle and risk factors with diabetes regulation were observed to be important for renal cancer patients. Multicenter studies are needed in larger series for more accurate results.
