Interventions to Promote Cancer Awareness and Early Presentation: Systematic Review
Low cancer awareness contributes to delay in presentation for cancer symptoms and may lead to delay in cancer diagnosis. The aim of this study was to review the evidence for the effectiveness of interventions to raise cancer awareness and promote early presentation in cancer to inform policy and future research. We searched bibliographic databases and reference lists for randomised controlled trials of interventions delivered to individuals, and controlled or uncontrolled studies of interventions delivered to communities. We found some evidence that interventions delivered to individuals modestly increase cancer awareness in the short term and insufficient evidence that they promote early presentation. We found limited evidence that public education campaigns reduce stage at presentation of breast cancer, malignant melanoma and retinoblastoma
Somatic mutations of KIT in familial testicular germ cell tumours
Somatic mutations of the KIT gene have been reported in mast cell diseases and gastrointestinal stromal tumours. Recently, they have also been found in mediastinal and testicular germ cell tumours (TGCTs), particularly in cases with bilateral disease. We screened the KIT coding sequence (except exon 1) for germline mutations in 240 pedigrees with two or more cases of TGCT. No germline mutations were found. Exons 10, 11 and 17 of KIT were examined for somatic mutations in 123 TGCT from 93 multiple-case testicular cancer families. Five somatic mutations were identified; four were missense amino acid substitutions in exon 17 and one was a 12bp in-frame deletion in exon 11. Two of seven TGCT from cases with bilateral disease carried KIT mutations compared with 3 out 116 unilateral cases (p = 0.026). The results indicate that somatic KIT mutations are implicated in the development of a minority of familial as well as sporadic TGCT. They also lend support to the hypothesis that KIT mutations primarily take place during embryogenesis such that primordial germ cells with KIT mutations are distributed to both testes
Genome-wide linkage screen for testicular germ cell tumour susceptibility loci
A family history of disease is a strong risk factor for testicular germ cell tumour (TGCT). In order to identify the location of putative TGCT susceptibility gene(s) we conducted a linkage search in 237 pedigrees with two or more cases of TGCT. One hundred and seventy-nine pedigrees were evaluated genome-wide with an average inter-marker distance of 10 cM. An additional 58 pedigrees were used to more intensively investigate several genomic regions of interest. Genetic linkage analysis was performed with the ALLEGRO software using two model-based parametric analyses and a non-parametric analysis. Six genomic regions on chromosomes 2p23, 3p12, 3q26, 12p13-q21, 18q21-q23 and Xq27 showed heterogeneity LOD (HLOD) scores of greater than 1, with a maximum HLOD of 1.94 at 3q26. Genome-wide simulation studies indicate that the observed number of HLOD peaks greater than one does not differ significantly from that expected by chance. A TGCT locus at Xq27 has been previously reported. Of the 237 pedigrees examined in this study, 66 were previously unstudied at Xq27, no evidence for linkage to this region was observed in this new pedigree set. Overall, the results indicate that no single major locus can account for the majority of the familial aggregation of TGCT, and suggests that multiple susceptibility loci with weak effects contribute to the diseas
Ramucirumab plus docetaxel versus placebo plus docetaxel in patients with locally advanced or metastatic urothelial carcinoma after platinum-based therapy (RANGE): a randomised, double-blind, phase 3 trial
Few treatments with a distinct mechanism of action are available for patients with platinum-refractory advanced or metastatic urothelial carcinoma. We assessed the efficacy and safety of treatment with docetaxel plus either ramucirumab-a human IgG1 VEGFR-2 antagonist-or placebo in this patient population

Az enzalutamid klinikai hatásossága és biztonságossága metasztatikus, kasztrációrezisztens prosztatarákban: szisztematikus irodalomkeresés és metaanalÃzis
Enzalutamide, abiraterone-acetate, and cabazitaxel are licensed post-docetaxel treatments of metastatic castration-resistant prostate cancer (mCRPC) in Hungary. The objectives of the study were to assess the efficacy and safety of post-docetaxel enzalutamide treatment and to compare it with abiraterone and with cabazitaxel, using Medline-based systematic literature search, and meta-analysis of randomised controlled trials (RCT). Overall 3 RCTs were included, one for each substance. Compared to placebo, enzalutamide proved significant efficacy in each primary and secondary endpoint. Enzalutamide extended median overall survival by 4.8 months. Due to lack of a common comparator in the cabazitaxel trial, only enzalutamide and abiraterone were involved in an indirect comparison. No significant difference was identified either in the primary endpoint (overall survival) (HR: 0.97, 95% CI: 0.75-1.25) or in frequencies of adverse events between these two treatments. However, enzalutamide was significantly more efficacious than abiraterone in 3 secondary endpoints: time to prostate-specific antigen (PSA) progression (HR: 0.43, 95% CI: 0.31-0.59), radiographic progression-free survival (HR: 0.6, 95% CI: 0.5-0.72), and PSA response rate (RR: 7.48, 95% CI: 2.83-19.72). Enzalutamide therapy proved clinical efficacy and safety in patients with post-docetaxel mCRPC. In the indirect comparison, efficacy and safety of abiraterone and enzalutamide were found to be similar
