Treatment results for hypopharyngeal cancer by different treatment strategies and its secondary primary- an experience in Taiwan

<p>Abstract</p> <p>Purpose</p> <p>The aim of this study was to evaluate treatment results in our hypopharyngeal cancer patients.</p> <p>Patients and Methods</p> <p>A total of three hundred and ninety five hypopharyngeal cancer patients received radical treatment at our hospital; 96% were male. The majority were habitual smokers (88%), alcohol drinkers (73%) and/or betel quid chewers (51%). All patients received a CT scan or MRI for tumor staging before treatment. The stage distribution was stage I: 2 (0.5%); stage II: 22 (5.6%); stage III: 57 (14.4%) and stage IV: 314 (79.5%). Radical surgery was used first in 81 patients (20.5%), and the remaining patients (79.5%) received organ preservation-intended treatment (OPIT). In the OPIT group, 46 patients received radiotherapy alone, 156 patients received chemotherapy followed by radiotherapy (CT/RT) and 112 patients received concomitant chemo-radiotherapy (CCRT).</p> <p>Results</p> <p>The five-year overall survival rates for stages I/II, III and IV were 49.5%, 47.4% and 18.6%, respectively. There was no significant difference in overall and disease-specific survival rates between patients who received radical surgery first and those who received OPIT. In the OPIT group, CCRT tended to preserve the larynx better (p = 0.088), with three-year larynx preservation rates of 44.8% for CCRT and 27.2% for CT/RT. Thirty-seven patients developed a second malignancy, with an annual incidence of 4.6%.</p> <p>Conclusions</p> <p>There was no survival difference between OPIT and radical surgery in hypopharyngeal cancer patients at our hospital. CCRT may offer better laryngeal preservation than RT alone or CT/RT. However, prospective studies are still needed to confirm this finding. Additionally, second primary cancers are another important issue for hypopharyngeal cancer management.</p

Fine-mapping of prostate cancer susceptibility loci in a large meta-analysis identifies candidate causal variants.

Prostate cancer is a polygenic disease with a large heritable component. A number of common, low-penetrance prostate cancer risk loci have been identified through GWAS. Here we apply the Bayesian multivariate variable selection algorithm JAM to fine-map 84 prostate cancer susceptibility loci, using summary data from a large European ancestry meta-analysis. We observe evidence for multiple independent signals at 12 regions and 99 risk signals overall. Only 15 original GWAS tag SNPs remain among the catalogue of candidate variants identified; the remainder are replaced by more likely candidates. Biological annotation of our credible set of variants indicates significant enrichment within promoter and enhancer elements, and transcription factor-binding sites, including AR, ERG and FOXA1. In 40 regions at least one variant is colocalised with an eQTL in prostate cancer tissue. The refined set of candidate variants substantially increase the proportion of familial relative risk explained by these known susceptibility regions, which highlights the importance of fine-mapping studies and has implications for clinical risk profiling

How do Canadian racialized sport media personalities influence conversations within digital spaces?

My proposed research paper will explore how Canadian racialized personalities within digital sports media are using their platforms as a form of resistance and athlete activism. Firstly, I will examine the sport digital media discourse. Using spatial theory, I plan to focus on the resistance of dominant stereotypes/narratives of racialized groups within digital media spaces. The third part of my research paper is to investigate, using anti-colonial theory and critical race theory, if and how digital media interrupt dominant narratives of sport in Canada. Do Canadian racialized personalities in digital sport media serve as a major catalyst to initiate a new discourse in sport? Do such voices in the digital sport media space influence social change? We have seen some examples of individual acts of athlete activism that has influenced conversations and resulted in significant impact beyond the scoreboard including #notyourmascot, #takeaknee, #likeagirl, #FIBAAllowHijab and #BeBoldForChange. My paper will research how Canadian racialized personalities in the digital sports media space influence people’s attitudes, beliefs and perceptions towards sports? How does the Canadian racialized digital sport media contribute to the movement for equality in sport
