19/09/2017Looking at cell metabolism instead of histology, EPFL scientists have identified new biomarkers that could help more accurately classify the two main subtypes of hepatoblastoma, a children liver cancer. Hepatoblastoma is a rare pediatric liver cancer, usually diagnosed in the first three years of life.
19/09/2017To fight infections cells in the immune system play a dangerous game with their own genes. Damaging genes allows B cells to make antibodies that are specifically equipped to target to specific causes of illness, but damaging genes also puts them at risk of becoming cancerous.
13/09/2017Liver cancer is the second-leading cause of cancer-related death and represents the fastest rising cancer worldwide. In most cases, the tumor develops in patients with chronic liver disease. Such diseases include chronic infections with hepatitis viruses or a so-called fatty liver due to nutritional or genetically caused lipometabolic disorders or an excessive consumption of alcohol.
11/09/2017IBS biologists discovered a key regulator of normal as well as pathological formation of new blood vessels.
11/09/2017Patients with head and neck squamous cell carcinoma who are positive for human papilloma virus (HPV-positive) have been observed to respond significantly better to chemo-radiotherapy than HPV-negative patients. This observation is surprising because HPV infection leads to an increased risk of developing oropharyngeal cancer. To date, the reason for this dichotomy has not been well understood.
06/09/2017Ground breaking research could reduce the recurrence of prostate cancer in males, a new study in the journal Nature Communications reports.
05/09/2017Researchers are moving closer to realizing the clinical potential of drugs that have previously been shown to support healthy aging in animals.
01/09/2017Many people are affected by heart disease today because - among other reasons- our modern unhealthy lifestyle is taking a toll on our hearts. A reliable diagnosis and treatment are crucial for patients with heart disease since all other organs depend on the pumping of our vital organ. Modern imaging techniques are a key to understanding the heart.
31/08/2017UT Southwestern Medical Center researchers report for the first time that tumors stressed by cancer immunotherapy release their mitochondrial DNA into nearby immune cells, triggering a host alert system.
25/08/2017According to the current doctrine, cancer cells develop due to mutations in genomic DNA. But could it be also caused also by faulty RNA molecules? A number of clues are pointing to this surprising hypothesis.
24/08/2017Being able to predict the resistance or sensitivity of a tumour cell to a drug is a key success-factor of cancer precision therapy. But such a prediction is made difficult by the fact that genetic alterations in tumours change dynamically over time and are often interdependent, following a pattern that is poorly understood.
24/08/2017The discovery of a new biological pathway involved in pain processing offers hope of using existing cancer drugs to replace the use of opioids in chronic pain treatment, according to scientists at McGill University.
23/08/2017There may be no silver bullet for treating liver cancer or fatty liver disease, but knowing the right targets will help science develop the most effective treatments. Researchers in Sweden have just identified a number of drug targets that can be used in the development of new efficient treatment strategies with minimum side effects.
22/08/2017Physics has always supported medical science, especially when it comes to practical implementation. Now physicists and health professionals join in collaborative research at an interdisciplinary Center in Erlangen and incorporate fundamental principles of theoretical physics in their studies of diseases.
18/08/2017The most aggressive variant of brain tumour – glioblastoma – has an average survival rate of 15 months. There is therefore an urgent need for new treatment strategies for this group of patients. A research team from Lund University in Sweden has now identified new factors which may affect the tumour cells’ ability to resist treatment.
16/08/2017Scientists from the University of Würzburg have synthesized a complex sugar molecule which specifically binds to the tumor protein Galectin-1. This could help to recognize tumors at an early stage and to combat them in a targeted manner
14/08/2017Every year, just over 1000 people are diagnosed with kidney cancer in Sweden. The three most common variants are clear cell, papillary and chromophobe renal cancer. Researchers compare the gene expression in tumour cells from a kidney cancer patient with cells from healthy tissue to figure out in which part of the kidney the cancer began and what went wrong in these cells.
10/08/2017In their final year of life, on average men cause more healthcare costs than women. Dying is more expensive in the French- and Italian-speaking parts of Switzerland than in the German-speaking part. These are the findings of an analysis of health insurance data that was conducted as part of the National Research Programme "End of life" (NRP 67).
27/07/2017How well cancer patients fared after chemotherapy was affected by their social interaction with other patients during treatment, according to a new study by researchers at the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health, and the University of Oxford in the United Kingdom.
19/07/2017Fanconi anemia is a rare genetic disease characterized by high cancer risk. Researchers of the University of Würzburg now have revealed a new Fanconi anemia gene that is involved in complex DNA repair processes and may also play a relevant role in cancer prevention.
10/07/2017Radiation therapies are an essential component of today’s oncology because they enable the treatment of localized tumors. Yet they have one major drawback: radiation damages not just tumor cells but also healthy tissue. One solution to solve this problem could be proton minibeam therapy, which uses finely focused beams.
07/07/2017At the end of May, the Joint Committee of the German Research Foundation (DFG) decided on the funding for Collaborative Research Centers (Sonderforschungsbereiche, SFBs). The Helmholtz Zentrum München is participating in three of the selected projects. A total of around 5.3 million euros will be distributed to the participating institutes over a period of four years starting on July 1.
06/07/2017Lung cancer screening is likely to be cost-effective, particularly if it also identifies other tobacco-related conditions in high-risk people, suggests new research published in the Journal of Thoracic Oncology (JTO).
05/07/2017Over millions of years of evolution, cells have developed myriad ways of regulating the processes that enable them to thrive. Especially useful tools have been saved, or "conserved," over the eons, so that today we can find them in a broad spectrum of life forms, from the very primitive to the most complex. New research sheds light on how one such conserved mechanism works.
03/07/2017Elastography, sometimes referred as seismology of the human body, is an emerging technology used to enhance medical ultrasound imaging. It does this by measuring the elasticity of biological tissue to diagnose cancer or liver and thyroid disease more accurately and at the earliest stages.
03/07/2017Not all lasers are the same – especially in the surgical field, it all depends on what’s inside: the different operational wavelengths of laser light also affect human tissue in different ways. This is why a single laser for a variety of applications drastically simplifies the job of physicians.
03/07/2017The scalpel is considered the classic surgical instrument and as such, has remained unchanged for quite some time. However, today’s technology opens up a world of new possibilities for cutting tissue. Next to high-frequency electrosurgical scalpels that work with electric power, surgeons also use a variety of different lasers. They promise great usability and better treatment.
03/07/2017Photodynamic therapy is often used to treat brain tumors because of its specificity - it can target very small regions containing cancerous cells while sparing the normal cells around it from damage. It works by injecting a drug called a photosensitizer into the bloodstream, where it gathers in cells, and then exposing the drug-filled cells to light.
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.
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.
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.
