Treatment breakthrough for advanced bladder cancer

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…

Potential predictive biomarker for response to PD-L1 checkpoint blocker found

The antibody drug, known as MPDL3280A, inhibits the brake protein, PD-L1, reviving the response by immune killer T cells, which target and destroy the cancer cells. In recent clinical trials, the PD-L1 checkpoint blocker caused impressive shrinkage of kidney, melanoma, and lung tumors. But, as with other immunotherapy drugs, many patients saw no benefit. …

Trial shows new imaging system may cut X-ray exposure for liver cancer patients

In a report prepared for presentation Dec. 3 at the 100th annual meeting of the Radiological Society of North America in Chicago (abstract #SSM24-02), the researchers described the results of a clinical trial of the imaging system AlluraClarity, made by Philips Healthcare, on 50 patients with liver cancer. …

Genetic testing could improve breast cancer prevention — ScienceDaily

Their study showed that prevention strategies could be improved by testing not only as currently for major cancer predisposition genes such as BRCA1 and BRCA2 — which identify a small percentage of women at very high risk — but also by factoring in data on multiple gene variants that individually have only a small effect on risk, but are more common in the population. The research was carried out by researchers at The Institute of Cancer Research, London, and the National Cancer Institute in Bethesda, US — and is published in the Journal of the National Cancer Institute. The study received funding from The Institute of Cancer Research (ICR), Breakthrough Breast Cancer and the National Cancer Institute. Researchers stressed that their study was a computer modelling analysis and would need to be confirmed by further research aimed at validating the models they used and assessing real-life prevention approaches…

Hedgehog signaling pathway for breast cancer identified — ScienceDaily

Scientists at The University of Texas MD Anderson Cancer Center report that hedgehog, a unique cell signaling pathway known to contribute to many types of cancer, may be behind breast cancer metastasis. This molecular message service works with the lncRNA known as BCAR4 giving the genetic green light for tumor growth. “Our study of BCAR4 and the hedgehog signaling pathway has provided evidence for lncRNAs’ regulator roles in aggressive breast cancers progression,” said Liuqing Yang, Ph.D., assistant professor of molecular and cellular oncology, whose findings are published in this month’s issue of Cell…

Cheap malaria drug could treat colorectal cancer effectively too, say experts

A pilot study by researchers at St George’s, University of London, has found the drug artesunate, which is a widely used anti-malaria medicine, had a promising effect on reducing the multiplication of tumour cells in colorectal cancer patients who were already going to have their cancer surgically removed. Colorectal cancer (CRC) makes up about 10 percent of the annual 746,000 global cancer cases in men and 614,000 cases in women. …

Establishment of induced pluripotent stem cells from Werner syndrome fibroblasts

Werner syndrome is characterized by the premature appearance of features associated with normal aging and cancer predisposition. This syndrome occurs frequently in Japan, affecting 1 in 20,000 to 1 in 40,000 people. The therapeutic methods for this disease are very limited and it is expected that iPS cells can be used for the development of innovative therapies…
