Global health experts call into question sub-Saharan cancer data

Cancer data compiled by the World Health Organisation’s (WHO) GLOBOCAN project has huge global influence and is used by Governments and international NGOs to determine health and funding priorities in sub-Saharan Africa. However, no independent evaluation of the data has ever been undertaken. For the first time, experts from Queen Mary University of London have critically evaluated all publically available information on the quality of cancer registration systems in sub-Saharan Africa. …

Zinc test could help diagnose breast cancer early

In a world-first the researchers were able to show that changes in the isotopic composition of zinc, which can be detected in a person’s breast tissue, could make it possible to identify a ‘biomarker’ (a measurable indicator) of early breast cancer. A report of the research by the Oxford University-led team, which included researchers from Imperial College London and the Natural History Museum, London, is published in the Royal Society of Chemistry journal Metallomics. The pilot study analysed zinc in the blood and blood serum of ten subjects (five breast cancer patients and five healthy controls) alongside a range of breast tissue samples from breast cancer patients…

Improved treatment for cancer patients: Topical steroid cream

Radiotherapy uses X-rays to destroy cancer cells but this can often lead to a severe skin reaction involving redness, pain and blistering similar to sunburn. The trial of this cream — mometasone furoate–was so successful that the patients in the research will now be offered this instead of the existing treatment. Breast cancer patients were recruited from hospitals all over the North West for the trial, based at the Rosemere Cancer Centre at the Royal Preston Hospital. Dr Andrew Hindley of Rosemere Cancer Centre: “We believe that this treatment should be considered the standard of care when a radiation therapy schedule is administered to an anatomical site where severe dermatitis would be predicted.” The patients were offered either diprobase cream or mometasone furoate to be administered daily from the start of radiation therapy for 5 weeks and for at least a fortnight afterwards. …

Trial results reveal first targeted treatment to boost survival for esophageal cancer

Up to one in six patients with esophageal cancer were found to have EGFR duplication in their tumor cells and taking the drug gefitinib, which targets this fault, boosted their survival by up to six months, and sometimes beyond. This is the first treatment for advanced esophageal cancer shown to improve survival in patients whose initial course of chemotherapy treatment has failed. It is also the first time a targeted treatment of any kind has proved effective in this disease, although chemotherapy and some targeted drugs have shown benefit in the second line treatment of other cancers of the digestive system including stomach cancer…

Decoding the emergence of metastatic cancer stem cells

“Cells have genetic circuits that are used to switch certain behaviors on and off,” said biophysicist Eshel Ben-Jacob, a senior investigator at Rice’s Center for Theoretical Biological Physics and co-author of a new study in the Journal of the Royal Society Interface. “Though some of the circuits for metastasis have been mapped, this is the first study to examine how cancer uses two of those circuits, in concert, to produce not just cancer stem cells, but also dangerous packs of hybrid stem-like-cells that travel in groups to colonize other parts of the body.” Metastasis — the spread of cancer between organs — causes more than 90 percent of cancer deaths, but not all tumor cells can metastasize…

More than 70% of young oncologists in Europe suffer symptoms of burnout

“Oncology is an exceptionally rewarding career, but it can be demanding and stressful at times,” said Dr Susana Banerjee, lead author of the study and a consultant medical oncologist at The Royal Marsden NHS Trust in London, UK. “Oncologists make complex decisions about cancer management, supervise the use of toxic therapies, work long hours, and continually face patients suffering and dying,” she said…

Why we should vaccinate boys against HPV as well as girls

Gillian Prue, from the School of Nursing and Midwifery at Queen’s University of Belfast, says that the human papillomavirus (HPV) infection is common in men and can lead to genital warts and the development of some head and neck, anal or penile cancers. She says incidence of this has increased in the past two decades with HPV causing 5% of all human cancers. …

Potential ‘universal’ blood test for cancer discovered

The test will enable doctors to rule out cancer in patients presenting with certain symptoms, saving time and preventing costly and unnecessary invasive procedures such as colonoscopies and biopsies being carried out. Alternatively, it could be a useful aid for investigating patients who are suspected of having a cancer that is currently hard to diagnose. Early results have shown the method gives a high degree of accuracy diagnosing cancer and pre-cancerous conditions from the blood of patients with melanoma, colon cancer and lung cancer. …
