Possibilities for personalized vaccines — ScienceDaily

“One of the biggest hurdles in cancer immunotherapy is the discovery of appropriate cancer targets that can be recognised by T-cells,” said Singh, who is scientific coordinator of the EU-funded GAPVAC phase I trial which is testing personalised vaccines in glioblastoma, the most common and aggressive brain cancer. “In the GAPVAC trial we will treat glioblastoma patients with vaccines that are ideal for each patient because they contain personalised antigens.”1 For all patients in the GAPVAC study, researchers will identify genes expressed in the tumour, peptides presented on the human leukocyte antigen (HLA) receptor (i.e…

New ways to drain cancer’s ‘fuel tank’ discovered — ScienceDaily

Cancer stem cells are particularly difficult to eradicate and are at the heart of why it is so hard to more effectively treat cancer patients, as the post-treatment survival of cancer stem cells drives tumor recurrence, the systemic spread of cancer and, ultimately, treatment failure. The researchers, based at the University’s Institute of Cancer Sciences and the Cancer Research UK Manchester Institute — both part of the Manchester Cancer Research Centre — investigated the role of mitochondria which produce and release energy within cells…

New model of follow up for breast cancer patients — ScienceDaily

International guidelines recommend annual follow-up mammograms for every woman after treatment for early breast cancer, regardless of the risk of her cancer returning. There is also no strong evidence to support annual mammography compared with other possible mammography schedules. …

New insights into breast cancer spread could yield better tests and treatments — ScienceDaily

According to the National Cancer Institute, more than 232,000 American women developed breast cancer last year and nearly 40,000 women died from the disease. It is the most common cancer among women in the United States. Most breast cancer deaths occur because the cancer has spread, or metastasized, which means that cells in the primary tumor have invaded blood vessels and traveled via the bloodstream to form tumors elsewhere in the body…

Pathology specialist contributes to debate on breast cancer gene screening — ScienceDaily

Glenn E. Palomaki, PhD, associate director of the Division of Medical Screening and Special Testing in the Department of Pathology and Laboratory Medicine at Women & Infants Hospital of Rhode Island has recently published an invited commentary in the November issue of Genetics in Medicine…

Quality of biopsy directly linked to survival in patients with bladder cancer — ScienceDaily

The two-year study found that about half of bladder cancer patients who were biopsied had insufficient material — meaning there was no bladder wall muscle retrieved — to accurately stage the cancer. Additionally, the UCLA research team found that a suboptimal biopsy and incorrect tumor staging was associated with a significant increase in deaths from bladder cancer, said study first author Dr…

Treatment breakthrough for advanced bladder cancer — ScienceDaily

Published today in Nature, the study examined an antibody (MPDL3280A) which blocks a protein (PD-L1) thought to help cancer cells evade immune detection. In a phase one, multi-centre international clinical trial, 68 patients with advanced bladder cancer (who had failed all other standard treatments such as chemotherapy) received MPDL3280A, a cancer immunotherapy medicine being developed by Roche. In addition, patients were all tested for the protein PD-L1 and around 30 were identified as having PD-L1 positive tumours. After six weeks of treatment, 43 per cent of PD-L1-positive patients found their tumour had shrunk…
