The findings, published in the journal Lancet Oncology, investigated the timing of trastuzumab administration with anthracycline and taxane chemotherapy. "In a previous MD Anderson study concurrent administration of trastuzumab with chemotherapy, including anthracyclines, demonstrated high pathologic complete response rates in breast cancer patients with HER-2-positive disease," Buzdar said. …
"Use of a balloon allows you to stabilize the anatomy. But what we show is that imprecision with balloon placement could reduce radiation dose coverage over the intended area," says Moyed Miften, PhD, FAAPM, investigator at the CU Cancer Center and chief physicist at the University of Colorado School of Medicine Department of Radiation Oncology. Specifically, Miften and colleagues including Bernard Jones, Gregory Gan, and Brian Kavanagh studied the technique known as stereotactic body radiation, in which powerful, precisely-targeted radiation is delivered only to cancerous areas of the prostate with the hope of killing tumor tissue. An endorectal balloon is needed to hold the prostate in place while this high dose is delivered…
"We all have a unique composition of hereditary variants of genes that affects how both our body and the tumor react to cancer treatment," Ola Myklebost tells us. He is Professor of Molecular Biology in the Department of Biosciences at the University of Oslo, and also holds a post at the Institute for Cancer Research at Oslo University Hospital. Professor Myklebost has now received a grant of NOK 75 million from the Research Council of Norway to develop the idea for next generation cancer treatment — personalized cancer therapy, directed specifically towards the various mutation faults in cancerous tumors…
Now, University of Pennsylvania researchers have revealed how a reduction in mitochondrial DNA content leads human breast cancer cells to take on aggressive, metastatic properties. The work, published in the journal Oncogene, breaks new ground in understanding why some cancers progress and spread faster than others and may offer clinicians a biomarker that would distinguish patients with particularly aggressive forms of disease, helping personalize treatment approaches. The study was led by the Penn School of Veterinary Medicine’s Manti Guha, a senior research investigator, and Narayan Avadhani, Harriet Ellison Woodward Professor of Biochemistry in the Department of Animal Biology. Additional Penn Vet collaborators included Satish Srinivasan, Gordon Ruthel, Anna K. …
"Gastric cancer is one of the most common causes of cancer-related mortality worldwide, especially in Asian countries," says Wei-Jung Chen, PhD, of the Department of Biotechnology and Animal Science of National Ilan University, Taiwan Republic of China. "In general, the main curative therapies for gastric cancer are surgery and chemotherapy, which are generally only successful if the cancer is diagnosed at an early stage. Novel treatment strategies to improve prognosis are urgently needed." Investigators evaluated the effects of three peptide fragments derived from lactoferricin B, a peptide in milk that has antimicrobial properties. …

"Two recent phase III trials of another anti-angiogenic drug, bevacizumab, showed no improvement in overall survival for glioblastoma patients, but our study suggests that only a subset of such patients will really benefit from these drugs," explains Tracy Batchelor, MD, director of the Pappas Center for Neuro-Oncology at the MGH Cancer Center and co-lead and corresponding author of the current study. "Our results also verify that normalization of tumor vasculature appears to be the way that anti-angiogenic drugs enhance the activity of chemotherapy and radiation treatment." Anti-angiogenic drugs, which block the action of factors that stimulate the growth of blood vessels, were first introduced for cancer treatment under the theory that they would act by ‘starving’ tumors of their blood supply…
The study, published October 29 in the open access journal PLOS Biology, analyzes how the timing of gene expression is regulated in the notochord, the evolutionary and developmental precursor of the backbone. The notochord is the main feature that sets humans, mice, sea squirts and related animals (collectively known as chordates) apart from flies, worms and mollusks, and is essential for their development. A crucial player in the development of the notochord is the Brachyury gene, which encodes a DNA-binding protein that switches on the expression of numerous notochord genes and ensures their sequential deployment during the formation of this pivotal structure…
A study of nearly eight million Swedes aged 15 and over found that among the 12,669 young people diagnosed with cancer between the age of 15 and 30 there was a 60% increased risk of suicide or attempted suicide. The risk was highest during the first year immediately after diagnosis when suicidal behaviour was 1.5-fold (150%) higher among the cancer patients compared with the cancer-free group. Dr Donghao Lu, a PhD student in the Department of Medical Epidemiology and Biostatistics, Karolinska Institutet (Stockholm, Sweden), said: "We found that there were 22 suicides among the cancer patients versus 14 expected and 136 attempts at suicide versus 80 expected. This equates to an extra 64 instances of suicidal behaviour among the 12,669 young cancer people…
