Loophole for cancer cells

Many cancers only become a mortal danger if they form metastases elsewhere in the body. Such secondary tumours are formed when individual cells break away from the main tumour and travel through the bloodstream to distant areas of the body. To do so, they have to pass through the walls of small blood vessels. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim and…

How tumors adapt to become more aggressive

One of the many reasons tumors are so difficult to treat is that they are able to adapt whenever they are exposed to unfavorable conditions. Hypoxia, or a lack of oxygen, is one example of a phenomenon that should weaken the tumor, but instead, the malignant cells are able to compensate and drive more aggressive disease behavior.

Breast tumors evolve in response to hormone therapy

Many breast tumors grow in response to female hormones, especially estrogen. Drugs that reduce estrogen levels in the body often are effective in reducing tumor size and preventing recurrence of the cancer. But some tumors become resistant to these therapies and continue to grow and spread.

New Biomarker for cancer immunotherapy?

The Ligand PD-L1 is one of the most important targets for cancer immunotherapy with checkpoint inhibitors. But not all tumors have sufficient quantities of PD-L1 ligands on their surface. Scientists from the German Cancer Consortium (DKTK) have now shown that different types of cancer possess different quantities of PD-L1-Gen copies. Genetic analysis of the PD-L1 gene may in the future help to…

3D printed kidney helps save woman's organ

Doctors and scientists at Intermountain Medical Center in Salt Lake City printed and used a 3D kidney to help save a patient's organ during a complicated tumor-removal procedural. The 3D-printed model allowed doctors to study the patient's kidney in 3D to determine how to best remove the tumor as it was located in a precarious location adjacent to vital arteries and veins. Thanks to the model of…

Molecular sub-groups in early stages of bladder cancer

Bladder cancer is a frequent disease affecting approximately 1,900 persons in Denmark annually. A high number of these patients only have superficial tumours in the bladder when the disease is diagnosed. For many years, this patient group will be examined frequently and during this time many get new tumours; some cases develop aggressively making it necessary to remove the bladder or receive…

Promising treatment prospects for invasive breast cancer

Scientists from the University of Zurich have been able to understand for the first time why many cancer cells adapt relatively quickly to the treatment with therapeutic antibodies in invasive forms of breast cancer. Instead of dying off, they are merely rendered inactive. The researchers have now developed an active substance that kills the cancer cells very effectively without harming healthy…

How printing a 3-D skull helped save a real one

What started as a stuffy-nose and mild cold symptoms for 15-year-old Parker Turchan led to a far more serious diagnosis: a rare type of tumor in his nose and sinuses that extended through his skull near his brain. “He had always been a healthy kid, so we never imagined he had a tumor,” said Parker’s father, Karl. “We didn’t even know you could get a tumor in the back of your nose.”

The story of the silent killer

Pancreatic cancer: Enzyme renders tumors resistant

Scientists at the German Cancer Research Center (DKFZ) and the Stem Cell Institute HI-STEM in Heidelberg have discovered the reason why some pancreatic tumors are so resistant to treatment. They have found that these tumor cells produce larger quantities of an enzyme that usually occurs in the liver and degrades many drugs. If this enzyme is blocked, the cancer cells become sensitive towards…

Stopping tumour cells killing surrounding tissue

Tumours kill off surrounding cells to make room to grow, according to new research from the University of Cambridge. Although the study was carried out using fruit flies, its findings suggest that drugs to prevent, rather than encourage, cell death might be effective at fighting cancer – contrary to how many of the current chemotherapy drugs work.

Imaging 'toolkit' to help identify new brain tumor drug targets

Stopping the growth of blood vessels in tumours is a key target for glioblastoma therapies, and imaging methods are essential for initial diagnosis and monitoring the effects of treatments. While mapping vessels in tumours has proven a challenge, researchers have now developed a combined magnetic resonance imaging (MRI) and ultramicroscopy 'toolkit' to study vessel growth in glioma models in more…

Cancer cells poised for growth when opportunity knocks

Researchers have identified a mechanism that allows cancer cells to respond and grow rapidly when levels of sugar in the blood rise. This may help to explain why people who develop conditions in which they have chronically high sugar levels in their blood, such as obesity, also have an increased risk of developing certain types of cancer.

Injectable agent illuminates cancer during surgery

Doctors at the Duke University School of Medicine have tested a new injectable agent that causes cancer cells in a tumor to fluoresce, potentially increasing a surgeon’s ability to locate and remove all of a cancerous tumor on the first attempt. The imaging technology was developed through collaboration with scientists at Duke, the Massachusetts Institute of Technology (MIT) and Lumicell Inc.

Gene variation promotes uncontrolled cell division

Mom’s eyes and dad’s tumor? Cancer is due to genetic defects, some of which can be hereditary. The gene variant rs351855, for example, occurs in one in two cancer patients. A team headed by Axel Ullrich from the Max Planck Institute of Biochemistry in Martinsried identified the gene variant a decade ago. Now, they succeeded for the first time in showing that the variation exposes an otherwise…
