Resistance of cancer cells against therapeutic agents is a major cause of treatment failure, especially in recurrent diseases. An international team around the biochemists Robert Ahrends from the University of Vienna and Jan Medenbach from the University of Regensburg identified a novel mechanism of chemoresistance which has now been published in "Nature Communications". It is driven by…
Each year almost 80,000 new patients in France alone receive fluoropyrimidines, a group of anti-cancer drugs including 5-FU which is normally administered intravenously to treat digestive, breast and head and neck cancer. However, fluoropyrimidines-based chemotherapies can cause severe toxicities (incidence at around 20%) and sometimes lethal toxicity (incidence between 0.1 and 1%) with part of…
Scientists have determined a new way to protect the hair follicle from chemotherapy in an effort to prevent hair loss as a result of cancer treatments. Researchers based at The University of Manchester have discovered a new strategy for how to protect hair follicles from chemotherapy, which could lead to new treatments that prevent chemotherapy-induced hair loss – arguably one of the most…
Researchers at the University of Helsinki in collaboration with researchers from Åbo Akademi University (Finland) and Huazhong University of Science and Technology (China) have developed a new anti-cancer nanomedicine for targeted cancer chemotherapy. This new nano-tool provides a new approach to use cell-based nanomedicines for efficient cancer chemotherapy. Exosomes contain various molecular…
A drug developed by US physician-scientists and chemists speeds up the regeneration of mouse and human blood stem cells after exposure to radiation. If the results can be replicated in humans, the compound could help people recover quicker from chemotherapy, radiation and bone marrow transplants. The study, published in Nature Communications, also sheds light on the basic biology behind blood…
An anti-inflammatory drug called ketorolac, given before surgery, can promote long-term survival in animal models of cancer metastasis, a team of scientists has found. Furthermore, so-called "pro-resolution" therapies can also trigger the immune system to eliminate metastatic cells. The research also suggests that flanking chemotherapy with anti-inflammatory drugs can unleash anti-tumor…
Fluoropyrimidine-based chemotherapies are widely used, at least in the European area, for treating various types of cancer including digestive, breast, throat and brain cancer. Fluoropyrimidines are a group of anticancer drugs including the well-known 5-FluoroUracil (5-FU) and the prodrug capecitabine.
A novel imaging technique that uses a synthesized form of scorpion venom to light up brain tumors has shown promise in a clinical trial. The imaging system enables neurosurgeons to better see malignant growths that often are difficult to fully eliminate.
A breast cancer test has been found that helps doctors make treatment decisions for some breast cancer patients, following research carried out at Queen Mary University of London and funded by Cancer Research UK. The test was successful in predicting whether chemotherapy would be beneficial for patients with the most common type of breast cancer (oestrogen-receptor positive, HER2-negative),…
Cognitive impairment associated with cancer, also known as “chemobrain”, has gained recognition as a complication of the disease and its treatment, as it can negatively affect the daily lives of cancer patients and survivors. Chemobrain can be subtle yet persistent, with some cancer patients reporting difficulties related to memory and attention even months after completing their treatment.…
Test more accurately identifies four mutations for which FDA-approved drugs exist and offers faster turn-around time between initial testing and commencement of therapy.
Cancer patients who undergo chemotherapy could soon benefit from a new AI that is able to identify and predict the development of different combinations of symptoms – helping to alleviate much of the distress caused by their occurrence and severity. In the first study of its kind, published by Nature Scientific Reports, researchers from the University of Surrey and the University of California…
The selection of a first-line chemotherapy drug to treat many types of cancer is often a clear-cut decision governed by standard-of-care protocols, but what drug should be used next if the first one fails? That’s where Georgia Institute of Technology researchers believe their new open source decision support tool could come in. Using machine learning to analyze RNA expression tied to…
A research team led by Arun Iyer, Ph.D., assistant professor of pharmaceutical sciences in the Eugene Applebaum College of Pharmacy and Health Sciences at Wayne State University, has developed a nanoplatform technology that works in combination with existing chemotherapeutic drugs that may reverse drug-resistance in renal cell carcinoma.
A new method predicts the course of HPV-negative head and neck cancer after radiation chemotherapy. According to a recent article in the journal ‘Clinical Cancer Research’, five microRNAs (miRNAs) can provide the decisive data. The work was conducted at the Helmholtz Zentrum München and the University Hospital of the Ludwig-Maximilians-Universität München (LMU) in close collaboration with…
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.
‘Scalp cooling successfully prevents alopecia in breast cancer patients undergoing anthracycline or taxane-based chemotherapy’, according to the latest clinical data published in The Breast. The paper, written by clinicians from the Berlin Oncology Center, Germany, revealed that 71% of women who took part on the study retained their hair as a result of using the Paxman Scalp Cooler. Scalp…
Blood is the juice of life, as while circulating through the body it delivers vital substances such as oxygen and nutrients to cells and tissues. Chemotherapy, radiotherapy and blood loss in general impoverish the system. A special kind of cells in the bone marrow, called hematopoietic stem cells (HSCs) is able to replenish the impoverished system by giving rise not only to red blood cells, but…
A small study of adults with the most common form of pancreatic cancer adds to evidence that patients with BRCA1 or BRCA2 gene mutations long linked to a high risk of breast cancer have poorer overall survival rates than those without the mutations. The same study also found that those with BRCA1 or BRCA2 had better survival rates with platinum-based chemotherapy, compared with similar patients…
A thin copper wire wrapped around a channel slightly thicker than a strand of hair could be the key to manufacturing a compact electronic device capable of counting white blood cells from the comfort of one’s home, a Kennesaw State University researcher says. Hoseon Lee, an assistant professor of electrical engineering in the Southern Polytechnic College of Engineering and Engineering…
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.
A new optical imaging system developed at Columbia University uses red and near-infrared light to identify breast cancer patients who will respond to chemotherapy. The imaging system may be able to predict response to chemotherapy as early as two weeks after beginning treatment. Findings from a first pilot study of the new imaging system—a noninvasive method of measuring blood flow dynamics in…
Avoidance of side-effects of chemotherapy is particularly important in the elderly, but finding the balance between reduced toxicity and maximum effectiveness is not always easy. A trial carried out by the European Organisation for Research and Treatment of Cancer, published in The Lancet Oncology, shows that, in older patients with HER2 positive metastatic breast cancer (an aggressive breast…
Genentech researchers have identified an enzyme that shifts pancreatic cancer cells to a more aggressive, drug-resistant state by epigenetically modifying the cells’ chromatin. The study, which will be published in the Journal of Cell Biology, suggests that targeting this enzyme could make pancreatic cancer cells more vulnerable to existing therapies that currently have only limited effect…
Cornell researchers have taken a major step toward answering a key question in cancer research: Why is testicular cancer so responsive to chemotherapy, even after it metastasizes? Professional cyclist Lance Armstrong, for example, had testicular cancer that spread to his lung and brain, yet he made a full recovery after conventional chemotherapy. The key to such success appears to lie in the…
