08/12/2016A study headed by Salvador Aznar Benitah, ICREA researcher at the Institute for Research in Biomedicine (IRB Barcelona), and published today in Nature identifies metastasis-initiating cells through a specific marker, namely the protein CD36. This protein, which is found in the membranes of tumour cells, is responsible for taking up fatty acids.
05/12/2016A large analysis of current research shows that people who eat at least 20g of nuts a day have a lower risk of heart disease, cancer and other diseases.
02/12/2016An optical fiber probe can distinguish cancer tissue and normal tissue at the margins of a tumor being excised, in real time, by detecting the difference in pH between the two types of tissue. This has the potential to help surgeons avoid removing too much healthy tissue during surgery and also avoid performing additional surgeries later to remove any cancer tissue left behind.
30/11/2016Massachusetts General Hospital (MGH) investigators have developed new methods for mapping and measuring solid stress - the force exerted by solid and elastic components - within tumors, an accomplishment that may lead to improved understanding of those forces and their consequences and to novel treatment strategies.
25/11/2016Recognizing the reasons people worry about a potential cancer diagnosis could help ease concern and encourage people with possible cancer symptoms to see their doctor earlier.
24/11/2016A team of Norwegian, French and Australian researchers is the first in the world to succeed in quantifying the effects of radiation on individual cancer cells. This means that radiation therapies can now be tailored to individual tumors and thus be more effective.
15/11/2016Despite steady progress in detection and treatment in recent decades, cancer remains the second leading cause of death in the United States, cutting short the lives of approximately 500,000 people each year.
04/11/2016A team headed by scientists from the Department of Biosystems at ETH Zurich in Basel has developed a cell culture technology platform for testing interactions between chemical and pharmaceutical compounds and three-dimensional body tissue samples.
03/11/2016Inflammatory bowel disease (IBD) is a complex condition that requires a lifetime of care and increases a person's cancer risk. But its origins are still a mystery. Now, a team of researchers have created a new culture model of the human intestine where living tissue from a patient biopsy can be preserved and studied for days.
21/10/2016Bottom Line: Among Japanese patients with esophageal cancer, those whose cancer tested positive for DNA from the bacterium Fusobacterium nucleatum had shorter cancer-specific survival compared with those whose cancer had no DNA from the bacterium.
20/10/2016A diagnosis of pancreatic cancer is often a death sentence because chemotherapy and radiation have little impact on the disease. In the U.S. this year, some 53,000 new cases will be diagnosed, and 42,000 patients will die of the disease. But research now being reported in ACS Nano could eventually lead to a new type of treatment based on gold nanoparticles.
19/10/2016Washington State University researchers have developed a low-cost, portable laboratory on a smartphone that can analyze several samples at once to catch a cancer biomarker, producing lab quality results.
17/10/2016A new imaging technique is under development with the aim of detecting and characterizing early cancerous changes in the gastrointestinal (GI) tract
10/10/2016Over 5000 patients with metastatic melanoma in Europe are denied access to new, life saving drugs every year, according to a survey presented at the ESMO 2016 Congress in Copenhagen.
05/10/2016The fight against cancer is a marathon, fought step by step, inch by inch. While breakthroughs may be rare, a new study from the Faculty of Medicine & Dentistry is giving greater insight into the growth of cancer cells and bringing researchers one step closer to the finish line.
26/09/2016A clinical trial for types of advanced cancer is the first of its kind to show that precision medicine - or tailoring treatment for individual people - can slow down the time it takes for a tumor to grow back, according to research presented at the Molecular Analysis for Personalized Therapy (MAP) conference.
22/09/2016Deaths from ovarian cancer fell worldwide between 2002 and 2012 and are predicted to continue to decline in the USA, European Union (EU) and, though to a smaller degree, in Japan by 2020, according to new research published in the leading cancer journal Annals of Oncology.
19/09/2016Jumping genes, so-called transposons, reproduce as parasites in the genome. This selfish behavior can be an evolutionary advantage for the organism or harm it. There is still a debate about the factors controlling the activity of transposons.
16/09/2016Researchers at the National Cancer Institute in the USA and the Babraham Institute, UK, have discovered how a mineral ion leaked from tumour tissue as it dies acts to stop the work of anti-tumour immune cells. This discovery provides a new approach in the development of treatments to engage the immune system in the fight against cancer.
13/09/2016Specifically training oncologists and their patients to have high-quality discussions improves communication, but troubling gaps still exist between the two groups, according to a new study in "JAMA Oncology".
12/09/2016Individual cells within a tumor are not all the same. This may sound like a modern medical truism, but it wasn't very long ago that oncologists assumed that taking a single biopsy from a patient's tumor would be an accurate reflection of the physiological and genetic make-up of the entire mass.
09/09/2016Researchers at the University of Adelaide have shown how a complex mix of plant compounds derived from ancient clinical practice in China – a Traditional Chinese Medicine – works to kill cancer cells.
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
01/10/2015A 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.
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.
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.
01/06/2015A 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.
01/06/2015Can 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.
01/06/2015When 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.
04/05/2015There 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.
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.
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.
03/02/2014Shortening 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.
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.
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.
