More than 30 years ago, a groundbreaking analysis by famed British researchers, Richard Doll and Richard Peto, calculated that 30 percent of all cancer deaths in the United States were caused by smoking. Since that time, no new estimate of this percentage has been published in the scientific literature. …
Medulloblastoma is the most common brain tumor in children, and its treatment remains inefficient. The work of a team of researchers led by Luca Tiberi and Pierre Vanderhaeghen (Universit� libre de Bruxelles (ULB), WELBIO, IRIBHM and ULB Neuroscience Institute (UNI)) opens new perspectives on the diagnosis and treatment of these brain tumors…
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. …
The data, presented at the 56th annual meeting of the American Society of Hematology, suggest that it may be possible to genomically screen ALL patients for their risk of long-term treatment-related effects on memory, attention and learning and to study potential interventions. …
Targeted therapy with radiopharmaceuticals–radioactive compounds used in nuclear medicine for diagnosis or treatment–has great potential for the treatment of cancer, especially for cancer cells that have migrated from primary tumors to lymph nodes and secondary organs such as bone marrow. These disseminated tumor cells can be difficult to treat with a single targeting agent because there are dramatic differences in the number of targetable receptors on each cell. …
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. …
Researchers behind a study at The University of Texas MD Anderson Cancer Center believe they may have found a molecule-based approach to halting 3q26.2’s destructive nature. …
The study suggests that attacking those subsets with targeted drugs may degrade the disease’s ability to spread throughout the bone marrow of affected patients, the authors say. The discovery was made by developing a mouse model of the disease that enabled researchers to track which of 15 genetic groups — or subclones — of myeloma cells spread beyond their initial site in the animals’ hind legs. By labeling the different subgroups with fluorescent dyes, researchers determined that just one of the subclones was responsible for the disease metastasis. They then compared the pattern of gene abnormalities in the initial myeloma tissue and the metastatic tumors. …
There are concerns the vaccine, which guards against four types of the HPV shown to cause cervical cancer and anogenital warts, may give girls a false sense of security about contracting sexually transmitted infections (STIs) and lead them to engage in riskier sexual activity. “These findings suggest fears of increased risky sexual behaviour following HPV vaccination are unwarranted and should not be a barrier to vaccinating at a young age,” says Dr. Smith, the lead author on the study that was published in the Canadian Medical Association Journal. This study looked at a cohort of 260,493 girls, of whom about half (128,712) were eligible for Ontario’s publicly funded, school-based HPV vaccination program during the first two school years it was offered (2007-08 and 2008-09). …
The researchers also showed that derangement in the methylation process has a direct bearing on the effectiveness of cancer therapy. In patients with chronic lymphocytic leukemia (CLL), they found that treatment produced shorter remissions if the tumor tissue showed signs of highly disorganized methylation. The findings demonstrate that such disorganization can actually benefit tumors and render them less vulnerable to anti-cancer drugs. …
