An unexpected discovery that could bring new hope to cancer patients worldwide: Researchers from the University of California San Diego have identified a mechanism that could predict response to immunotherapy. The most effective weapon against the tumors may be handed to the scientists by the cancer cells themselves.
The exchange of a single amino acid building block in a metabolic enzyme can lead to cancer. In addition, it can impair the immune system. It thus blocks the body’s immune response in the battle against the mutant molecule and also impedes immunotherapy against brain cancer. This finding opens new insights into cancer development and progression and it also suggests that rethinking antitumor…
Canadian researchers have found a promising way to stop tumour cells from multiplying. In disrupting the composition of ribosomes, the team from Université de Montréal (UdeM) discovered a direct molecular mechanism to stop cancer cells from proliferating, which is called senescence. Their results have been published in Nature Cell Biology. “Ribosomes are complex machines composed of both…
Babraham Institute researchers have shown that some tumours use not one but two levels of protection against the immune system. Knocking out one level boosted the protective effects of the second and vice versa. The research demonstrates that a two-pronged approach targeting both cell types simultaneously may offer a promising route for the development of new cancer immunotherapies.
Recently, scientists have explored another version of embolization, called gas embolotherapy. During this process, the blood supply is cut off using acoustic droplet vaporization (ADV), which uses microscopic gas bubbles induced by exposure to ultrasonic waves. A team of researchers from China and France has discovered that these bubbles could also be used as potential drug delivery systems.
Menarini Silicon Biosystems announced that a new study has found that using circulating tumor cells (CTCs), a form of liquid biopsy, holds promise as a key tool for developing a staging system that can have a significant impact in the treatment of metastatic breast cancer (MBC). In this study, the largest CTCs pooled analysis study to date, researchers determined that the CTC count could be used…
Making tumour cells glow: Medical physicists at Martin Luther University Halle-Wittenberg (MLU) have developed a new method that can generate detailed three-dimensional images of the body's interior. This can be used to more closely investigate the development of cancer cells in the body. The research group presents its findings in "Communication Physics", a journal published by the…
Cancer is a disease often driven by mutations in genes. As researchers learn more about these genes, and the proteins they code for, they are seeking smarter drugs to target them. The ultimate goal is to find ways to stop cancer cells from multiplying out of control, thereby blocking the growth and spread of tumors. Now researchers from The Scripps Research Institute are reporting an innovative…
Taking a biopsy of a brain tumor is a complicated and invasive surgical process, but a team of researchers at Washington University in St. Louis is developing a way that allows them to detect tumor biomarkers through a simple blood test. Hong Chen, a biomedical engineer, and Eric C. Leuthardt, MD, a neurosurgeon, led a team of engineers, physicians and researchers who have developed a…
A multidisciplinary team of scientists share recent advancements in innovative in-vitro cancer biology methods for screening drug-like molecules in cancer tissue relevant models in a new report published online ahead-of-print at SLAS Discovery. Entitled Advanced Development of Primary Pancreatic Organoid Tumor Models for High-Throughput Phenotypic Drug Screening, the report can be accessed for…
Belly fat affects the odds of women surviving kidney cancer but not men, according to a new study by researchers at Washington University School of Medicine in St. Louis. Half of female kidney cancer patients with substantial abdominal fat at the time of diagnosis died within 3 1/2 years, while more than half of women with little belly fat were still alive 10 years later, the researchers found.…
A new imaging technology to grade tumour biopsies has been developed by a team of scientists led by the Department of Physics and the Department of Surgery and Cancer at Imperial College London. Publishing their results in the journal Convergent Science Physical Oncology, they describe how their new method promises to significantly reduce the subjectivity and variability in grading the severity…
What effect does a particular cancer medicine or radiation therapy have on patients? To find out, physicians use CT images to determine whether a tumor’s size changes during the course of treatment. In the PANTHER project, a joint team of experts aims at gaining further valuable information from these images. In the future, doctors will be able to find out at an early stage whether a cancer…
Testing cancer drugs on miniature replicas of a patient’s tumour could help doctors tell in advance which treatments will work, a major new study reports. The exciting new technique involves growing ‘mini tumours’ from biopsy samples – and could help end reliance on trial and error in selecting cancer treatments for patients where genetic tests are not predictive of response. Researchers…
Scientists at the University of Delaware and the University of Illinois at Chicago have found a new way to kill liver cancer cells and inhibit tumor growth. First, they silence a key cellular enzyme, and then they add a powerful drug. They describe their methods in a new paper published in Nature Communications. This research could accelerate the development of new treatments for liver cancer,…
A new Michigan State University study is helping to answer a pressing question among scientists of just how close mice are to people when it comes to researching cancer. The findings, now published in PLOS Genetics, reveal how mice can actually mimic human breast cancer tissue and its genes, even more so than previously thought, as well as other cancers including lung, oral and esophagus.…
The most common type of tumor found in the kidney is generally quite small (less than 1.5 in). These tumors are usually found by accident when CAT scans are performed for other reasons and the serendipitous finding poses a problem for doctors. Are these tumors malignant and do they need to be surgically removed because they may threaten the patient’s life? Or are they benign and can be left…
Lars Schimmöller MD, associate professor of radiology at Düsseldorf University Hospital, tackled current diagnosis of prostate cancer (PCa) and addressed tumour detection, staging, active surveillance and recurrence during the Medica Academy session on Imaging Update. He also highlighted how MRI helps improve biopsies and avoid unnecessary surgery in PCa.
Cancer therapies including radiation and chemotherapy seek to treat the disease by killing tumor cells. Now a team including researchers at Beth Israel Deaconess Medical Center (BIDMC) have shown that the dead and dying cancer cells generated by chemotherapy and targeted cancer therapy paradoxically trigger inflammation that promotes aggressive tumor growth. In a study published today in the…
Scientists are using their increasing knowledge of the complex interaction between cancer and the immune system to engineer increasingly potent anti-cancer vaccines. Now researchers at the National Institute of Biomedical Imaging and Bioengineering (NIBIB) have developed a synergistic nanovaccine packing DNA and RNA sequences that modulate the immune response, along with anti-tumor antigens, into…
Findings published in Oncotarget offer new hope for children with highly aggressive brain tumors like atypical teratoid/rhabdoid tumor (AT/RT) and medulloblastoma. Previously, the authors of the study have shown that an experimental drug that inhibits polo-like kinase 4 (PLK4) stopped pediatric brain tumor growth in vitro. Now, they have demonstrated its success in an animal model – the drug…
Selective internal radiotherapy (SIRT) is often only looked at from a palliative perspective. However, the procedure is now also increasingly moving into the curative field, as Prof. Dr. Jens Ricke, Chair of Radiology at the Ludwig-Maximilian University Munich and Director of the Clinic and Polyclinic for Radiology at the University Hospital of the LMU reports. “As a locoregionally used…
New navigation imaging and neurophysiological stimulation techniques enable an approach to brain tumours long considered unresectable before and during surgery, but not one does it quite as well as ultrasound, according to a leading Spanish neurosurgeon.
A group of international cancer researchers led by investigators from Mayo Clinic and University of New South Wales Sydney has found that the level of a type of white blood cell, called tumor-infiltrating lymphocytes, present in the tumors of patients with high-grade ovarian cancer may predict a patient’s survival. “We know that a type of tumor-infiltrating lymphocyte called cytotoxic CD8 are…
