Colorectal cancer screening programs are currently underutilized in Germany. This also applies to testing for blood in the stool. The immunological stool tests can detect tiny amounts of blood in the stool. Scientists at the German Cancer Research Center (DKFZ) have investigated whether smartphone-based testing could be a meaningful alternative or supplement to traditional laboratory tests.

In a published scientific study, researchers have succeeded in accurately diagnosing common types of brain tumors in children and adolescents based on tumor-derived genetic material in cerebrospinal fluid. Until now, these so-called liquid biopsies were not capable enough for such reliable diagnostics. The international research team has therefore optimized a sequencing technique and developed an AI-based computational method. In a later step,…

The risk of colorectal cancer can be predicted more accurately by determining seven blood-based micro-RNAs (miRNAs) than by using traditional methods - and can be done so many years before a diagnosis is made. In a current study, researchers from the German Cancer Research Center and the National Center for Tumor Diseases (NCT) Heidelberg show that miRNA profiles provide greater predictive accuracy than genetic or lifestyle-based risk…

More and more data from various European countries prove: Vaccination against human papillomavirus not only prevents precancerous lesions, but also reliably protects against cervical cancer. On the occasion of the International HPV Awareness Day on March 4, Nobel laureate Harald zur Hausen hopes that many more parents will recognize this unique opportunity to protect their children from preventable cancers by vaccinating against HPV.

Screening trials for the early detection of rare diseases often fail due to insufficient predictive power of the results. For the rare HPV-related cancer of the pharynx, scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) now relied on the combined detection of antibodies against two different viral proteins in a proof-of concept trial.

With the "Česká Hlava" awards, the Czech government has been honoring the country's most brilliant minds every year since 2002 and recognizing exceptional achievements in research, development and innovation.

The incidence of colorectal cancers in young adults is increasing. At the same time, the proportion of overweight and obese young people is also on the rise. Whether there is a connection between these two observations, however, was not known until now. Scientists at the DKFZ have now shown that the risk of early colorectal cancer is significantly increased in overweight young people compared to normal-weight peers.

After infections or blood loss, the body must compensate for the loss of blood cells as quickly as possible. This has long been considered the task of the hematopoietic stem cells in the bone marrow. But scientists at the German Cancer Research Center (DKFZ) have now discovered in mice that a certain population of progenitor cells takes over this task: This accelerates the regeneration of the blood cells.

A high-fat, high-sugar diet damages the liver in the long term.

Not only actual chronological age, but also individual aging at the molecular level is a key factor in the development of cancer. This was discovered by scientists at the DKFZ and the Saarland Cancer Registry. If the so-called “epigenetic clocks” indicate accelerated biological aging, the likelihood of a cancer diagnosis increases. This finding could help identify at-risk groups and make early detection screenings more targeted

It has long been suspected that endothelial cells play a key role in determining how the body’s immune system responds to tumors.

Brain tumour patients could benefit from heavy ion therapy

Glioblastoma is a malignant brain tumour. It does not respond anywhere near as well to conventional forms of therapy than other tumours because it contains particularly resistant cancer cells. Scientists at the Heidelberg Ion Beam Therapy Center (HIT) at Heidelberg University Hospital and the German Cancer Research Center have shown that heavy ion therapy is effective against these cells.

Genetic alterations that promote the development and spread of tumors are difficult to identify. This is especially true for mutations in the non-protein-coding regions of the genome, which include all important regulatory sequences. Scientists at the German Cancer Research Center have now published an algorithm that detects cancer drivers in both the protein-coding and non-coding regions of the genome.

Scientists from the German Cancer Research Center (DKFZ) and Medical Faculty Mannheim of the Heidelberg University investigated in mice how spreading tumor cells behave at the site of metastasis: Some tumor cells immediately start to form metastases. Others leave the blood vessel and may then enter a long period of dormancy. What determines which path the cancer cells take is their epigenetic status.

Evotec SE announced today the launch of beLAB2122 in the Rhine- Main-Neckar region to efficiently advance first-in-class therapeutic concepts into investable drug discovery projects. Mediated and supported by BioRN, Evotec’s newest BRIDGE brings together the European Molecular Biology Laboratory (“EMBL”), the German Cancer Research Center (“DKFZ”), the Goethe University Frankfurt, Heidelberg University and the University of Tübingen.

Scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have developed antibodies that have two antigen-binding sites and can couple cancer cells with effector cells of the immune system. In laboratory tests, these bridging antibodies, together with an enhancer antibody, were able to specifically mobilize the body's own immune defenses and destroy breast cancer cells.

Why do metastases often only appear after the original tumor has been surgically removed? Scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) and the Mannheim Medical Faculty of Heidelberg University have now published an explanation for this phenomenon. They were able to identify a messenger substance of the cancer cells that locally promotes the growth of the primary tumor.

How can camera images be used during minimally invasive surgeries to assess whether the operated organ is sufficiently perfused with blood? Scientists from the German Cancer Research Center (DKFZ) and the Städtisches Klinikum Karlsruhe have now succeeded in automatic monitoring of ischemia during a kidney surgery using only the optical properties of the tissue and not relying on injection of contrast agent.

Researchers at the German Cancer Research Center (DKFZ) have succeeded in identifying a resistance mechanism that often occurs in a specific targeted therapy against chronic lymphocytic leukemia (CLL). The drug ibrutinib is effective in many cases, but therapy resistance often develops during the course of treatment. In cell culture experiments and in mice, the resistance mechanism was successfully overcome using a second drug.

The cellular environment of a tumor can either support or sabotage recovery. The most comprehensive study to date on the tumor microenvironment in low-grade gliomas, conducted by KiTZ, Jena University Hospital, the DKFZ, and Heidelberg University Hospital, shows what a supportive or obstructive “neighborhood” looks like in childhood brain tumors. The study also provides clues as to how tumor communication might be blocked.

Tumors are not a comfortable place to live: oxygen deficiency, nutrient scarcity, and the accumulation of sometimes harmful metabolic products constantly stress cancer cells. A research team from the DKFZ and the IMP in Vienna has now discovered that the acidic pH value in tumor tissue is a decisive factor in how pancreatic cancer cells adapt their energy metabolism in order to survive under these adverse conditions.

Ependymomas, brain tumors that occur particularly in young children, are especially difficult to treat and more than half of the children affected have an increased risk of relapse. As part of an international consortium, the KiTZ, the DKFZ, the MFHD and UKHD have received a grant of 1.5 million pounds sterling (GBP) from the British organization The Brain Tumor Charity to develop a new type of immunotherapy for ependymoma.

Chemotherapy is often a central component of treatment for advanced colorectal cancer. However, not every therapy is equally effective for every patient. Researchers from the German Cancer Research Center (DKFZ), the HI-STEM* stem cell institute, and the biotech company Xilis in Utrecht, Netherlands, have now developed a new method for selecting the most effective drug before treatment begins.

For the first time, researchers have succeeded in mapping the organization of immune cells in human lymph nodes. The study was led by scientists from Heinrich Heine University Düsseldorf, Düsseldorf University Hospital, the DKFZ, the European Molecular Biology Laboratory (EMBL), and the Max Delbrück Center (MDC) in Berlin. They were able to demonstrate why the architecture of healthy lymph nodes is altered in malignant lymphomas.
