22/06/2017Globally, more than 2 billion children and adults suffer from health problems related to being overweight or obese, and an increasing percentage of people die from these health conditions, according to a new study.
21/06/2017Ultrasound-sensitive nanoparticle aggregates target toxic doses of chemotherapy drugs to tumors while minimizing systemic toxicity.
15/06/2017Young adults who had chemotherapy as a child have decreased cognitive flexibility and a weaker short-term memory. Their ability to concentrate and long-term memory are largely unaffected. Researchers from KU Leuven (University of Leuven) and University Hospitals Leuven present these findings in the Journal of the National Cancer Institute.
14/06/2017Radiation therapy (RT) using high-energy particles, like x-rays or electron beams, is a common and critical component in successfully treating patients with brain tumors, but it is also associated with significant adverse effects, such as neuronal loss in adjacent healthy tissues.
26/05/2017Difficulties in initiating or maintaining sleep at middle-age are associated with an increased risk of dementia, according to a new study from the University of Eastern Finland. The 20-year follow-up study was conducted among 2,682 men participating the Kuopio Ischaemic Heart Disease Study.
25/05/2017Once hailed as a breakthrough in cancer treatment, immunotherapies are now raising concerns as doctors note new side effects like severe allergic reactions, acute-onset diabetes and heart damage.
25/05/2017Most women diagnosed with ovarian cancer undergo surgery to remove as many of the tumors as possible. However, it is usually impossible to eliminate all of the cancer cells because they have spread throughout the abdomen. Surgery is therefore followed by 18 weeks of chemotherapy.
23/05/2017Earlier discovery of cancer and greater precision in the treatment process are the objectives of a new method developed by researchers at Sahlgrenska Academy and Boston University. Investments are now being made to roll out this innovation across healthcare and broaden the scope of the research in this field.
18/05/2017For women who miss a breast screening appointment, giving a fixed date and time for a new appointment could improve poor attendance and be a cost-effective way to shift national participation trends, according to an analysis led by Queen Mary University of London (QMUL).
17/05/2017New diagnoses for two types of skin cancer increased in recent years, according to a Mayo Clinic-led team of researchers. Their paper, published in "Mayo Clinic Proceedings", uses medical records from the Rochester Epidemiology Project to compare diagnoses of basal cell carcinoma and squamous cell carcinoma - both nonmelanoma skin cancers - between 2000 and 2010 to diagnoses in prior years.
12/05/2017The fight against skin cancer just got a new weapon. For years, melanoma researchers have studied samples that were considered uniform in size and color, making them easier to examine by more conventional means. But melanomas do not always come in the same shape and hue; often, melanomas are irregular and dark, making them difficult to investigate.
11/05/2017It is not often that a fall saves someone's life. Helen Powell, 74, says that was the case for her. A computerized tomography scan that followed her fall revealed a cancerous brain tumor that led her to Mayo Clinic and surgery using first-in-the-world technology. Brain magnetic resonance elastography (MRE) imaging, showed the precise firmness of her tumor.
04/05/2017Identification and functional validation of proteins involved in tumorigenesis are essential steps toward advancing cancer precision medicine. In The Journal of Clinical Investigation researchers now report the important role for FES in the initiation and progression of melanoma.
02/05/2017Researchers hope to use stem cells to heal burns, patch damaged heart tissue, even grow kidneys and other transplantable organs from scratch. This dream edges closer to reality, but one of the enduring puzzles for stem cell researchers is how these remarkable cells know when it's time for them to expand in numbers and transform into mature, adult cells in order to renew injured or aging tissue.
01/05/2017A collaborative Cleveland Clinic, University of Oxford and Moffitt Cancer Center team of researchers has proven the theory that, while resistance to targeted treatment in cancer is truly a moving target, there are opportunities to overcome the resistance that develops.
28/04/2017Traditional toxicological investigations performed on animals (in vivo) are expensive, time-consuming and may cause animal suffering. But research from Umeå University demonstrates that a neuronal cell model, derived from mouse, can be used to evaluate the neurotoxic effect of chemicals.
24/04/2017Liver cancer is the fifth most common malignant tumor in the world. The tumor can be removed through surgery or by utilizing thermal ablation techniques. If a treatment with conservative methods is no longer possible, there is an alternative: irreversible electroporation (IRE). The effectiveness of this method was now confirmed by a clinical study.
21/04/2017Second cancers in children and adolescents and young adults (AYA) are far deadlier than they are in older adults and may partially account for the relatively poor outcomes of cancer patients ages 15-39 overall, a new study by UC Davis researchers has found.
19/04/2017A new study by Yusheng Feng, professor of mechanical engineering at The University of Texas at San Antonio (UTSA), describes an algorithm that can predict the growth of cancerous tumors, which could help medical professionals judge the best treatment options for patients.
18/04/2017Researchers at Fred Hutchinson Cancer Research Center have developed biodegradable nanoparticles that can be used to genetically program immune cells to recognize and destroy cancer cells -- while the immune cells are still inside the body.
14/04/2017Most ovarian cancer is diagnosed at such late stages that patients' survival rates are poor. However, if the cancer is detected earlier, five-year survival rates can be greater than 90 percent. Now, MIT engineers have developed a far more sensitive way to reveal ovarian tumors.
06/04/2017A team of investigators has determined that young children participating in a clinical trial to assess the effectiveness of reduced radiotherapy did worse when there were deviations from the treatment protocol.
03/04/2017Genetic testing of tumor and blood fluid samples from people with and without one of the most aggressive forms of skin cancer has shown that two new blood tests can reliably detect previously unidentifiable forms of the disease.
31/03/2017From using fluid in the lungs to better understand the potential of immunotherapy treatments in lung cancer, to tracking circulating tumor cells in prostate cancer, to conducting RNA sequencing of cancer cell clusters from the blood of pancreatic cancer patients, a series of studies from the University of Pennsylvania demonstrate the promise of new diagnostic methods.
02/01/2017Our topic title "pediatric (children’s) oncology" evoked strong emotional reactions from several mothers and fathers of our staff. "This hits too close to home for me, I couldn’t write about it", or "How do people manage to deal with this?". And we are only on the sidelines; physicians, caregivers and nurses at the hospital, hospice or families at home are the ones that have the real tough job.
02/01/2017Treatments for children need to be different from treatment for adults – this also applies in oncology. Having said that, children do not just need new and different treatment concepts that still necessitate research. They also require the support from their families, who need to be nearby during treatment.
22/03/2016Medical apps like diabetes or high blood pressure diaries are becoming increasingly popular with smartphone users. There are many available choices out there but they are not always clear. Added to this is the question of how the data collected by the apps can be sensibly incorporated into treatment.
08/03/2016Pancreatic cancer is one of the deadliest forms of cancer because it is difficult to diagnose and only presents with symptoms in the later stages. In the future, a laboratory test developed at the Greifswald University Medicine could make an early detection of this type of cancer and consequently a faster and better treatment possible.
09/11/2015Interview with Professor Jürgen Weitz, Director of the Clinic and Polyclinic of Visceral, Thoracic, and Vascular Surgery, University Hospital Carl Gustav Carus at the Technical University Dresden
01/10/2015Semiconductor nanoparticles for biomedical applications have been researched for some time now. Not only are they millionths of a millimeter in size, they also offer great potential for cancer diagnostics and therapy, so-called theranostics. They enter cells, are activated by ultrasonic radiation and destroy the cells using the generated vibration.
01/10/2015It is a portmanteau, a mixture of two words. This way it saves us time and trouble while speaking because the human speech apparatus is lazy. And it describes a mixture of procedures: the combination of two procedures that would normally be separate in medicine. We are talking about theranostics.
01/10/2015A proper diagnosis is a part of great therapy. However, it can also be beneficial to be able to quickly respond to changes during a treatment. One example of this is the treatment of uterine myomas. Female patients at the University Hospital Bonn are treated using so-called high-intensity focused ultrasound, HIFU in short. Prof. Holger Strunk explains this procedure.
03/08/2015Endoradiotherapy can be very unpleasant for cancer patients, since it does not only harm tumor cells, but also healthy ones. Sometimes, patients even need to stop therapy because of the side effects. Physicians and researchers are thus continuously searching for ways to transport radiopharmaceuticals directly and exclusively to their target.
22/06/2015Bladder tumors have different growth characteristics. In most cases, they are limited to the inner wall of the bladder and thus well resectable. Unlike carcinoma in situ, which becomes muscle invasive after a certain amount of time. To be able to completely remove the tumor during resection, photodynamic diagnostics (PDD) can make sense.
01/06/2015Can liquid biopsies become the new trend in cancer diagnostics? The medical world has asked this question for quite some time. The first globally approved liquid biopsy-based test for lung cancer shows that this can work. Yet further findings and research are still required to establish this less invasive method in diagnostics.
01/06/2015A tumor is as unique as the person who is affected by it. For a long time, it was assumed this would make treatment more difficult since cancer drugs are not able to be one hundred percent effective in targeting the affected cells. In this interview with MEDICA.de, Professor Ugur Sahin explains why it is precisely these individual mutations that make him hopeful for a new type of therapy.
01/06/2015When cancer is diagnosed, the terms tumor markers or biomarkers keep popping up. They describe characteristics that are not found in healthy persons. The classic tumor markers can be easily detected in blood samples or other body fluids. Other analysis methods require more effort. Yet they all share one thing in common: biomarkers indicate a potential tumor.
04/05/2015Whether it is a mammogram, colonoscopy or a skin cancer screening – after a certain age, we are subject to various early cancer detection screenings. Yet many of us don’t know that these screening tests are also associated with risks. This is something what Dr. Sylvia Sänger from the University Medical Center Hamburg-Eppendorf discovered in a study.
04/05/2015Since the end of April 2015, the long-awaited evaluation report on the skin cancer screening programs offered by German health insurance providers is now finally available. We spoke with Dr. Ralph von Kiedrowski, Board Member of the German Dermatologist Association (German: Berufsverband Deutscher Dermatologen) on what the screening can accomplish and his take on the G-BA report.
04/05/2015There are many decisions to be made in an adult life; among them are cancer prevention screenings. They are voluntary and many people deliberate whether they should go or not and if they would actually want to know the results. Science, politics and health care professionals also ponder with each new preventive service whether it is beneficial and who should end up paying for it.
02/02/2015Only projects with a solid foundation are successful in the long run. This is also true for science. Biobanks are the most important component of this foundation when it comes to fundamental biomedical research: Only high quality tissue samples that are stored there make conclusive research possible - for example in search of the causes of tumorigenesis.
03/11/2014As an imaging procedure, magnetic resonance tomography has become essential in clinical practice, since it can easily make organs and tissue visible. However, until now abnormal cancer cells or small centers of inflammation remained almost invisible. Now cell biologists from Berlin, Germany, have succeeded in fixing this problem with xenon magnetic resonance imaging.
03/02/2014Differentiating tumor tissue from healthy tissue isn’t always easy for surgeons. Scattered cancer cells and early cancer are often hard to detect with the naked eye. A special camera now makes even the tiniest remainder of a tumor visible during surgery.
03/02/2014Shortening a time-consuming procedure from four hours to five minutes and automate it at the same time sounds like a dream come true for employees in all fields and industry sectors. This dream could soon become a reality for radiologists. Software could take away the tedious processing of CT images, which is required before cancer radiation therapy.
03/02/2014Radiologists usually do their work after oncologists when it comes to cancer treatment. Yet modern radiology also provides treatments at this point. MEDICA.de spoke with Professor Stefan Schönberg, Director of the Institute of Clinical Radiology and Nuclear Medicine at the University Medical Center Mannheim, Germany, about the use of a new computer tomograph and its benefits for patients.
05/01/2014Eventually, all adults need to see a physician for colon cancer prevention. While the exam goes by quickly thanks to sedation, it sometimes leads to a follow-up procedure if a growth in the colon could not be removed with the endoscope and requires open surgery.
