Using a new approach called 'reinforced learning', researchers have taught an artificial intelligence (AI) to responsibly choose the right amount of chemo- and radiotherapy for glioblastoma patients. The technique, which is insprired by behavioural psychology, has given the AI the ability to master the tightrope walk between effective tumor shrinkage and the medications' severe side effects.
Monash University’s Biomedicine Discovery Institute (BDI) researchers have identified a new mechanism used by Henipaviruses in infection, and potential new targets for antivirals to treat them. Their findings may also apply to other dangerous viruses.
A new augmented reality system to guide procedures in interventional oncology is currently taking its first steps. A three-step experiment proves this system to be precise and reliable enough to facilitate image guidance critical to the success of interventional oncology procedures. Using a back-face camera and a tablet PC to visualise the patient, the system projects 3D images of body structures…
It doesn’t often happen that army generals switch sides in the middle of a war, but when cancer is attacking, it may cause even a gene that acts as the body’s master defender to change allegiance. Researchers at the Weizmann Institute of Science have discovered that this gene’s betrayal can occur in more ways than previously appreciated – and might even return the renegade cells to their…
Robotic surgery is as effective as traditional open surgery in treating bladder cancer, according to a news study. 350 patients participated in the nationwide trial, who were randomly assigned to undergo robotic surgery or open surgery to remove cancerous bladders.
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…
MRI has developed rapidly over the past decade in Poland, where clinicians are combining MRI with PET and CT to highlight tumour growth or regression and perfusion. ‘The fact that MRI offers new software and programmes means we can diagnose pathologies more precisely and make a diagnosis faster than a few years ago,’ explained Poland’s national advisor on radiology and diagnostic imaging…
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.
Researchers have shown for the first time that a form of artificial intelligence or machine learning known as a deep learning convolutional neural network (CNN) is better than experienced dermatologists at detecting skin cancer. In a study published in the leading cancer journal Annals of Oncology, researchers in Germany, the USA and France trained a CNN to identify skin cancer by showing it more…
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…
Prostate cancer is one of the most common cancers diagnosed nationally among men. The National Cancer Institute estimates 161,000 were diagnosed in 2017. While there are many treatment options for men with prostate cancer, a recent national study published in the Journal of the American Medical Association compared the effectiveness of treatments for high-risk prostate cancer. Said Daniel Krauss,…
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…
Bracco Imaging S.p.A., a global leader in diagnostic imaging, announced a strategic partnership with R.A.W. S.r.l. - an Italian company focused on Augmented Reality Guidance technology in Interventional Oncology procedures - to expand its portfolio of solutions for Interventional Oncology. One of the key challenges clinicians have to face during interventional procedures is the precise…
Engineering researchers at the University of Arkansas have moved closer to developing an alternative method of detecting and possibly treating breast cancer. Terahertz images of breast tumors taken from mice accurately detected cancerous tissue with a high level of specificity.
Conventional chemotherapy in oncology is increasingly yielding to new procedures such as targeted therapy and immunotherapy. This results in changes for radiologists because new procedures require familiarisation with certain imaging to ensure that the treatment process is interpreted correctly.
What beats digital mammography to detect breast cancer in asymptomatic women? Digital breast tomosynthesis (DBT) – was a big discussion at RSNA 2017. Sarah M Friedewald MD, medical director of the Lynn Sage Comprehensive Breast Center of Northwestern Memorial Hospital in Chicago and its division chief of breast and women’s imaging, discussed the clinical implications of DBT for routine…
The development of new procedures to monitor cancer treatments is gathering momentum. One such innovation is liquid biopsy. This new lab technique allows non-invasive identification, characterisation and monitoring of circulating tumour DNA. Thus, liquid biopsy can potentially revolutionise oncological diagnostics – and put a spoke in the wheel of radiology. High time to act, says Professor Dr…
Tumor imaging technique has potential as anti-cancer weapon, mouse study shows.
Machine learning is playing an increasing role in computer-aided diagnosis, and Big Data is beginning to penetrate oncological imaging. However, some time may pass before it truly impacts on clinical practice, according to leading UK-based German researcher Professor Julia Schnabel, who spoke during the last ESMRMB annual meeting. Machine learning techniques are starting to reach levels of human…
Radiation therapy is a popular and effective treatment for many men with prostate cancer, and now a temporary gel offers greater protection for organs at risk during treatments. “Treating prostate cancer with radiation therapy can cause unintended injury to adjacent, healthy tissue, which can lead to bowel and urinary problems, as well as erectile dysfunction,” said Daniel Krauss, M.D., a…
St. Jude Children’s Research Hospital oncologists have discovered the cell type that gives rise to rhabdomyosarcoma, the most prevalent soft tissue cancer in children. Previously, scientists thought the cancer arose from immature muscle cells, because the tumor resembled muscle under the microscope. However, the St. Jude researchers discovered the cancer arises from immature progenitors that…
GE Healthcare has entered into a strategic, long-term partnership with Roche to jointly develop and co-market digital clinical decision support solutions. The partnership will initially focus on products that accelerate and improve individualized treatment options for cancer and critical care patients. The two companies aim to develop an industry-first digital platform, using advanced analytics…
When immune cells invade the tumor, this is usually considered a good sign because the body's own immune system appears to be responding to the cancer. In the case of certain types of breast cancer immune cells, namely so-called tumor-infiltrating lymphocytes (TILs), these can determine survival rates and predict the usefulness of chemotherapy. This was shown by the largest meta study on TIL…
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…
