Behind the Headlines' Top Five of Top Fives 2015

In this study, researchers wanted to see why this is and if there could be any human applications.Researchers collected white blood cells from African and Asian elephants. They found that elephants have at least 20 copies of a gene called TP53. TP53 is known to encourage cell "suicide" when DNA is damaged, stopping any potential cancer in its tracks. In contrast, humans are thought to have only a single copy of the TP53 gene.Of course the big question – the elephant in the room, if you will – is how we can boost TP53 activity in humans to stimulate a similar protective effect. The simple answer is: we don't know. Yet. Researchers 'a step closer' to universal flu vaccineIt's just like buses. You wait years for a potential universal flu vaccine, then two come along at once. In August, two studies were published, both on the possibility of creating a "one-size jab" for flu.The flu virus is shaped like a ball, with many "spikes" sticking out of its surface made of a chemical called haemagglutinin. The "stem" part of this spike does not change as much as its tip or other parts of the virus, so both of these studies aimed to develop a vaccine that targeted the stem. Targeting these areas may help keep the vaccines effective, even if new strains come along.Both vaccines were able to protect mice against what would usually be a lethal dose of flu, and one vaccine reduced fever symptoms in monkeys.While the results were encouraging, ...

Authors: Qiu S, Pellino G, Warren OJ, Mills S, Goldin R, Kontovounisios C, Tekkis PP Abstract Mixed adenoneuroendocrine carcinoma (MANEC) are rare cancers of the gastrointestinal (GI) and pancreatobiliary tract. They are characterized by the presence of a combination of epithelial and neuroendocrine elements, where each component represents at least 30% of the tumour. Review of literature and consolidation of clinicopathological data. Sixty-one cases of colorectal MANEC have been reported in literature and one seen in this centre. The median age of the patients affected was 61.9 ± 12.4 years (2...

CONCLUSIONS: β-Eudesmol may serve as a potential anti-CCA candidate particularly when used in combination with conventional chemotherapeutics. The mechanisms involved may be mediated via NQO1 suppression-related apoptosis pathway. PMID: 29914576 [PubMed - in process]

CONCLUSIONS: This current analysis showed no significant difference in stent thrombosis with the addition of cilostazol to the standard dual antiplatelet therapy during any follow-up time period after PCI. PMID: 29914573 [PubMed - in process]

Conclusion: Factors including a larger tumor size (diameter> 5cm), lymphovascular invasion, lymph node metastasis, synchronous metastasis and positive margin may increase the risk of recurrences of resected pancreatic SPTs. All SPTs should be excised and patients with high-risk features should undergo a long-term follow-up.

Oral cavity cancer is a type of head and neck squamous cell carcinoma (HNSCC) and contributes to significant morbidity and mortality each year. An epigenetic pathway of transcriptional inactivation for many genes has been described in various cancers, including HNSCC. For our study, we selected genes for which silencing caused by hypermethylation can promote cancer development. In 75 primary HNSCC tumours and paired surgical margins, we investigated the methylation status of the p16, APC, MGMT, TIMP3 and CDH1 gene promoters by methylation-specific PCR after bisulphite treatment. The promoter methylation rates of p16, APC, ...

Conclusions: Genomic and epigenetic signatures were validated in a larger and geographically separate cohort, from TCGA database, which reinforce their clinical applicability. Noninvasive methodologies for detection of these signatures require further studies before translation in to clinical practice.

This study was a retrospective analysis of the data related to 229 patients with newly diagnosed cervical cancer. The potential prognostic factors were evaluated by univariate and multivariate survival analysis. The correlation between CRP/Alb ratio and other prognostic factors were analyzed by Chi-Square or Fisher's exact test.Results: Multivariate analyses showed that CRP/Alb ratio was an independent predictor of overall survival (OS) in cervical squamous cell carcinoma (SCC) (HR, hazard ratio = 2.529; p = 0.045), but not in all cases of cervical cancer. However, NLR was a prognostic factor in the whole cervical cancer (...

This study examined the role of marital status on survival outcome of nasopharyngeal carcinoma (NPC) patients using a population-based cancer registry.Methods: Patients with primary NPC diagnosed between 2004 and 2013 were included using the Surveillance, Epidemiology and End Results program. Patient demographic, clinicopathologic features, management, and survival outcomes were compared according to marital status. Cause-specific survival (CSS, NPC-related death) for marital status was analyzed.Results: The data of 3018 patients were included, with 61.4%, 11.1%, 21.8, and 5.6% of patients married, divorced (or separated),...
