Abstract
The sole clinicopathological characteristic is not enough for the prediction of survival of patients with clear cell renal cell carcinoma (ccRCC). However, the survival prediction model constructed by machine learning technology for patients with ccRCC using clinicopathological features is rarely reported yet. In this study, a total of 5878 patients diagnosed as ccRCC from four independent patient cohorts were recruited. The least absolute shrinkage and selection operator analysis was implemented to identify optimal clinicopathological characteristics and calculate each coefficient to construct the prognosis model. In addition, weighted gene co-expression network and gene enrichment analysis associated with risk score were also carried out. Three clinicopathologic features were selected for the construction of the prognosis risk score model as the prognostic factors of ccRCC, including tumor size, tumor grade, and tumor stage. In the CPTAC (Clinical Proteomic Tumor Analysis Consortium) cohort, the General cohort, the SEER (Surveillance, Epidemiology, and End Results) cohort, and the Huashan cohort, patients with high-risk score had worse clinical outcomes than patients with low-risk score (hazard ratio 5.15, 4.64, 3.96, and 5.15, respectively). Further functional enrichment analysis demonstrated that our machine learning-based risk score was significantly connected with some cell proliferation-related pathways, consisting of DNA repair, cell division, and cell cycle. In summary, we developed and validated a machine learning-based prognosis prediction model, which might contribute to clinical decision-making for patients with ccRCC.

Abstract
AIMS Platinum-based chemoradiotherapy (CRT) as bladder conservation therapy has shown promising results for muscle-invasive bladder cancer. However, treatment-related toxicity remains a major consideration in therapeutic planning. Some common polymorphisms in genes involved in DNA repair (encoding enzymes that repair DNA damaged by platinum agents and ionizing radiation) are reported to result in modulation of the repair capacity. We investigated associations between functional genetic polymorphisms involved in DNA repair and acute toxicity of CRT to determine the predictive value of these polymorphisms for toxicity. MATERIALS & METHODS The study group comprised of 101 bladder cancer patients treated with platinum-based CRT, and seven polymorphisms in XPC (Lys939Gln, rs2228001), XPD (Lys751Gln, rs13181), XPG (Asp1104His, rs17655), XRCC1 (Arg399Gln, rs25487), XRCC3 (Thr241Met, rs861539), TP53 (Arg72Pro, rs1042522) and MDM2 (SNP309, T>G, rs2279744) were genotyped. RESULTS More than two total variant alleles in nucleotide excision repair genes, including XPC, XPD and XPG, were significantly associated with grade 3 or 4 neutropenia (adjusted odds ratio [aOR]: 6.8; 95% CI: 2.0-26; p = 0.0026). There were no significant associations between any genotypes and grade 2 or greater nausea/vomiting or diarrhea. Any grade 3 or 4 hematological toxicity was significantly associated with the Gln/Gln or Lys/Gln + Gln/Gln genotypes of XPC compared with Lys/Lys (aOR: 10; 95% CI: 2.0-65; p = 0.0070 or aOR: 6.3; 95% CI: 1.9-29; p = 0.0069; respectively). CONCLUSION These results suggest that nucleotide excision repair gene polymorphisms, especially in XPC, might potentially be predictive factors for acute toxicity of CRT for bladder cancer, helping individual patient selection for bladder conservation therapy. However, further studies with larger sample sizes are needed to draw final conclusions.

Abstract
Prostate cancer is the most commonly diagnosed cancer in men worldwide and is the second leading cause of cancer related mortality. Genetic background may account for the difference in susceptibility of individuals to different diseases and the relationship between genetic polymorphism and some diseases has been extensively studied. There are several common polymorphisms in genes encoding DNA repair enzymes, some of these polymorphisms are reported to result in subtle structural alterations of the repair enzyme and modulation of the repair capacity. The aim of the present study was to analyze the effect of XPG Asp 1104His and XRCC1 Arg309Gln polymorphisms on risk of prostate cancer in north Indian population. Statistically significant increased risk of prostate cancer was observed on individuals that posses His/His genotype of XPG (OR 2.53, 95% CI 0.99-6.56, P = 0.031). In this study 150 prostate cancer diagnosed patients, 150 healthy controls and 150 BPH (benign prostate hyper plasia) were recruited from north Indian population. Moreover, individuals that carried the Gln/Gln genotype of XRCC1 also showed statistically increased risk of prostate cancer (OR 2.06, 95% CI 1.07-4.00, P = 0.033). The Asp/Asp of XPG and Gln/Gln of XRCC1 in combination showed statistically increased risk of prostate cancer in cases (OR 3.29, 95% CI 1.09-10.16, P = 0.032).

Abstract
Apurinic/apyrimidinic endonuclease 1 (APE1) is a DNA repair protein, which plays important roles in the base excision repair (BER) pathway. Genetic variations of APE1 have been shown to influence an individual's susceptibility to carcinogenesis. We hypothesized the genetic polymorphisms of APE1 are associated with the risk of renal cell carcinoma (RCC). In a case-control study of 612 RCC patients and 632 age and sex matched healthy controls, we genotyped two APE1 functional polymorphisms (-656 T>G, rs1760944 and 1349 T>G, rs1130409) and assessed their associations with risk of RCC. We found that, compared with 1349 TT/TG genotypes, the variant genotype 1349 GG had a significantly increased RCC risk [adjusted odds ratio (OR) = 1.47, 95% confidence interval (CI) = 1.10-1.95], particularly among subgroups of BMI > 23 kg/m(2) (OR = 1.54, 95% CI = 1.06-2.22), male (OR = 1.70, 95% CI = 1.17-2.46), never smokers (OR = 1.56, 95% CI = 1.11-2.21), light smokers (OR = 2.01, 95%CI = 1.02-3.95), and drinkers (OR = 2.00, 95% CI = 1.13-3.54). Furthermore, the polymorphism was significantly associated with risk of developing localized stage RCC. No altered RCC risk was associated with the -656 T>G polymorphism, but we found individuals who were homozygous for both risk alleles of the two SNPs had a 2.17-fold increased risk for RCC, compared to individuals with 0 risk alleles. Our results suggest that polymorphisms of APE1 may confer susceptibility to RCC.

Abstract
OBJECTIVE To determine if the two common polymorphisms in the methylenetetrahydrofolate reductase (MTHFR) gene, C677T and A1298C, affect tumour aggressiveness or prognosis of clear cell renal cell carcinoma (CCRCC) in Japanese patients. PATIENTS AND METHODS MTHFR C677T and A1298C polymorphisms have been reported to cause decreased enzyme activity, which reduces the quantity of methyl groups available for DNA methylation and leads to mis-incorporation of uracil into DNA, resulting in single-strand DNA breaks. These effects might induce the accumulation of several genetic changes, leading to the development and progression of CCRCC. Therefore, we investigated the associations between MTHFR genotypes and haplotypes and the clinicopathological characteristics and survival rates in 240 Japanese patients with histopathologically confirmed CCRCC. MTHFR C677T and A1298C were genotyped and haplotypes were analysed using appropriate software. RESULTS The variant genotypes of MTHFR A1298C were significantly associated with some advanced characteristics of CCRCC in all patients, and these associations were stronger among men. However, among women, the variant genotypes of MTHFR C677T were associated with some advanced characteristics of CCRCC and the C677T variant genotypes or the 677T-1298A haplotype was significantly associated with decreased overall survival (P = 0.007 and P = 0.009, respectively). CONCLUSION To our knowledge, this is the first report on the association between MTHFR polymorphisms and CCRCC aggressiveness or prognosis. These results suggest that the MTHFR genotypes and haplotype might be useful, in a gender-specific manner, as predictive factors for the clinical course of CCRCC. Furthermore, these findings will contribute to the understanding of the mechanisms underlying CCRCC progression.

Abstract
Platinum-based chemoradiotherapy (CRT) as bladder conservation therapy has shown promising results for muscle-invasive bladder cancer. However, CRT might diminish survival as a result of the delay in cystectomy for some patients with non-responding bladder tumors. Because the p53 tumor suppression pathway, including its MDM2 counterpart, is important in chemotherapy- and radiotherapy-associated effects, functional polymorphisms in the TP53 and MDM2 genes could influence the response to treatment and the prognosis following CRT. We investigated associations between two such polymorphisms, and p53 overexpression, and response or survival in bladder cancer patients treated with CRT. The study group comprised 96 patients who underwent CRT for transitional cell carcinoma of the bladder. Single nucleotide polymorphisms (SNPs) in TP53 (codon 72, arginine > proline) and MDM2 (SNP309, T > G) were genotyped using PCR-RFLP, and nuclear expression levels of p53 were examined using immunohistochemistry. None of the genotypes or p53 overexpression was significantly associated with response to CRT. However, patients with MDM2 T / G + G / G genotypes had improved cancer-specific survival rates after CRT (P = 0.009). In multivariate analysis, the MDM2 T / G + G / G genotypes, and more than two of total variant alleles in TP53 and MDM2, were independently associated with improved cancer-specific survival (P = 0.031 and P = 0.015, respectively). In addition, MDM2 genotypes were significantly associated with cystectomy-free survival (P = 0.030). These results suggest that the TP53 and MDM2 genotypes might be useful prognostic factors following CRT in bladder cancer, helping patient selection for bladder conservation therapy.

Abstract
We analyzed renal cell cancer incidence patterns in the United States and reviewed recent epidemiologic evidence with regard to environmental and host genetic determinants of renal cell cancer risk. Renal cell cancer incidence rates continued to rise among all racial/ethnic groups in the United States, across all age groups, and for all tumor sizes, with the most rapid increases for localized stage disease and small tumors. Recent cohort studies confirmed the association of smoking, excess body weight, and hypertension with an elevated risk of renal cell cancer, and suggested that these factors can be modified to reduce the risk. There is increasing evidence for an inverse association between renal cell cancer risk and physical activity and moderate intake of alcohol. Occupational exposure to trichloroethylene has been positively associated with renal cell cancer risk in several recent studies, but its link with somatic mutations of the von Hippel-Lindau gene has not been confirmed. Studies of genetic polymorphisms in relation to renal cell cancer risk have produced mixed results, but genome-wide association studies with larger sample size and a more comprehensive approach are underway. Few epidemiologic studies have evaluated risk factors by subtypes of renal cell cancer defined by somatic mutations and other tumor markers.

Abstract
In this population-based case-control study with 325 Caucasian renal cell carcinoma (RCC) patients and 335 controls matched to cases by age, gender and county of residence, we evaluated the associations between 13 potential functional polymorphisms in nine major nucleotide excision repair (NER) genes and RCC risk. In individual single nucleotide polymorphism analysis, after adjustment for multiple comparisons, a significantly decreased RCC risk was observed for the heterozygous genotype of XPD Asp312Asn [odds ratio (OR) = 0.62; 95% confidence interval (CI): 0.43-0.90] and for the heterozygous and homozygous variant genotypes combined in a dominant model (OR = 0.64; 95% CI: 0.46-0.89). The heterozygous AG genotype of XPA 5'untranslated region was at 1.78-fold increased risk (95% CI: 1.18-2.69) and the risk reached 2.43-fold (95% CI: 1.57-3.75) for the homozygous variant GG genotype; the risk was significant both in the dominant model and in the recessive model. In joint analysis, compared with individuals with fewer than five adverse alleles, individuals with five (OR = 1.17; 95% CI: 0.71-1.93), six (OR = 1.66; 95% CI: 1.03-2.67), seven or more (OR = 1.85; 95% CI: 1.16-2.95) exhibited a progressively increased risk of RCC (P for trend = 0.004). Further, there were significant interactions between NER pathway genes and sex, hypertension and obesity (all P for interaction <0.05). Our results strongly support that common sequence variants of the NER pathway genes predispose susceptible individuals to increased risk of RCC and that the association may be modified by gender, history of hypertension and obesity. These results need to be replicated in larger studies.

Abstract
Upper urinary tract transitional cell carcinoma (UUT-TCC) is quite an uncommon disease, and its prognosis differs among individuals irrespective of tumor stage. DNA repair gene polymorphisms are reported to result in the modulation of the repair capacity and might influence the prognosis of UUT-TCC. We examined the associations between functional polymorphisms in five DNA repair genes, and the prognosis of UUT-TCC in 103 UUT-TCC patients. Variant alleles in xeroderma pigmentosum complementation group C, more than three total variant alleles in all DNA repair genes studied and more than two total variant alleles in three nucleotide excision repair genes were independently associated with improved overall and disease-specific survival of UUT-TCC patients in multivariate analysis (P = .0063 and P = .0005 for xeroderma pigmentosum complementation group C, P = .016 and P = .0016 for all genes, and P = .0053 and P = .018 for nucleotide excision repair genes, respectively). These results suggest that some DNA repair gene polymorphisms may preoperatively be valuable as prognostic factors for UUT-TCC beyond tumor stage and grade, helping to provide optimal treatment strategies for individual patients.
