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.

On March 23, 2022, the U.S. Food and Drug Administration (FDA) granted approval to the first targeted radioligand therapy against metastatic prostate cancer based on a joint patent of the German Cancer Research Center (DKFZ) and the University of Heidelberg. The agent significantly improves the chances of survival for those affected.

Team involving the University of Freiburg has developed a new analytical method for the basement membrane in human lungs.

So-called silent mutations have no effect on the composition of a protein. They are therefore not considered to promote cancer. However, scientists from the German Consortium for Translational Cancer Research (DKTK), partner site Essen, now describe in a case of kidney cancer an overlooked silent mutation with a major impact on prognosis.

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.

Through the Endeavour Awards, the Mark Foundation supports research projects that bring together scientists from different disciplines to advance the prevention, diagnosis and treatment of cancer. One of the only four Endeavour Awards presented this year goes to a project coordinated by scientists from the German Cancer Research Center (DKFZ).

Predicting the success of cancer treatment - 20/06/2023

Focusing on gut microbiome for CAR T-cell therapy

Cancer immunotherapies use the body's own defences to fight tumour cells. An international consortium of researchers from Germany and the USA led by the DKFZ in Heidelberg has demonstrated that the effectiveness of CAR T-cell therapies greatly depends on the composition of the gut microbiome. The researchers have also developed a model for predicting the long-term response to the treatment.

A new study published in Nature Medicine, July 2023 has identified two novel markers for screening high-grade squamous intraepithelial lesions (HSIL), a precursor to anal cancer, from the anal microbiome of people with HIV (PWH). PWH are at a significantly higher risk of developing anal cancer. Current screening methods, such as anal cytology, have low specificity for detecting HSIL, which hinders the prevention of anal cancer.

Colorectal cancer differs from patient to patient. That is why scientists are looking for characteristic tumors markers that allow to make predictions about the likely response to certain therapies and the individual prognosis. The aim is to identify colorectal cancer subtypes so that these can then be treated in a customized manner.

Scientists from the German Cancer Research Center (DKFZ) and Heidelberg University Hospital (UKHD) have shown that the combination of therapeutic immune cells, known as CAR T cells, and a bispecific antibody could improve the treatment of leukaemia.

Personalised therapies for treating metastasing breast cancer

Breast cancer is characterised by broad genetic diversity. Successful treatment is made even more difficult by the fact that, in advanced breast cancer, the properties of metastases often differ significantly from the primary tumour. The Heidelberg CATCH study is now collecting genetic profiles from patients' metastasis tissue samples, which can be used to tailor therapy to individual requirements.

Christiane Opitz, scientist at the German Cancer Research Center, is being awarded this year's Ita Askonas Prize of the European Federation of Immunological Societies. Opitz has discovered how tumor cells use certain metabolites to protect themselves against the immune system. Her research findings may provide important clues for the development of new therapeutic concepts.

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…

Tumor vaccines can help the body fight cancer. These vaccines alert the patient's immune system to proteins that are harbouring cancer-typical alterations.

Tumour monitoring using liquid biopsy

Liquid biopsy, the analysis of cancer biomarkers and circulating tumour cells in body fluids such as blood, is revolutionising the diagnosis and monitoring of cancer. It has also been possible to expand circulating tumour cells from the blood under laboratory conditions. It is expected that in the future, liquid biopsy will be able to precisely characterise tumour cells at every stage of a cancer.

Current diagnostic methods do not always reliably distinguish between chronic inflammation of the pancreas and pancreatic cancer. About one third of all diagnoses are inconclusive. Scientists from the German Cancer Research (DKFZ) and from Heidelberg University Hospital (UKHD) therefore searched for molecular markers that could specify this diagnosis.

CAR-T cell therapy is a last hope for many patients with blood, bone marrow or lymph gland cancer when other treatments are unsuccessful. A limiting factor of this very effective and safe therapy is that the cells used in the process quickly reach a state of exhaustion. Researchers at the University of Freiburg have now been able to prevent this exhaustion and thus significantly improve the effect of the therapy in a preclinical animal model.

The development of immunotherapies against blood cancer could be more successful if T cells are activated moderately rather than excessively. Scientists from the German Cancer Research Center have now been able to show this in mice: If the researchers blocked a cytokine that slows down the immune system, the T cells became exhausted and failed in the fight against leukemia.

Activated T cells that carry a certain marker protein on their surface are controlled by natural killer cells. In this way, the body presumably curbs destructive immune reactions. Researchers now discovered that NK cells can impair the effect of cancer therapies with immune checkpoint inhibitors in this way. They could also be responsible for the rapid decline of therapeutic CAR-T cells.

He and his team are using organoid models and stem cell-based systems and have succeeded in simultaneously cultivating all three main cell types of the pancreas from pluripotent stem cells.

Artificial intelligence (AI) can help dermatologists to detect skin cancer. However, many dermatologists distrust the algorithms' decisions, which they cannot comprehend. Scientists at the German Cancer Research Center have now developed an AI-based support system for skin cancer diagnostics that explains its decisions.

The International Agency for Research on Cancer (IARC), an agency of the World Health Organization (WHO), will soon publish the first edition of its classification of childhood cancers. The new WHO classification forms the basis of modern, precise cancer diagnostics for physicians and pediatric oncologists worldwide and is based on the latest international research findings.

Depending on whether the cell nucleus of an epithelial cell is located on the outer or inner side of the tissue, the genome is more or less acetylated - genes can therefore be translated easier or harder. Scientists from the German Cancer Research Center (DKFZ) have demonstrated this for the first time in the development of the Drosophila wing.

In multiple myeloma, a cancer of the bone marrow, relapse almost always occurs after treatment. Initially, most patients respond well to therapy. However, as the disease progresses, resistant cancer cells spread in the bone marrow, with fatal consequences for the patients.

Cytolytics GmbH - 14/02/2023

Bioinformatics meets medical diagnostics and drug development

The start-up company Cytolytics from Tübingen has developed a robust and user-friendly software platform that uses machine learning for the automated analysis of cells. This is beneficial in areas such as cancer diagnostics and the development of new pharmaceutically active substances.

Because of their highly active metabolism, many tumors are susceptible to a special type of cell death, ferroptosis. Nevertheless, cancer cells often manage to escape this fate. Scientists at the German Cancer Research Center have now discovered a new mechanism by which normal as well as cancer cells protect themselves against ferroptosis.

Cancer genomes are the result of diverse mutation processes. Scientists have analyzed the molecular evolution of tumors after exposure to mutagenic chemicals. DNA lesions that persists unrepaired over several cell generations lead to sequence variations at the site of damage. This enabled the researchers to distinguish the contribution of the triggering lesion from that of the subsequent repair in shaping the mutation pattern.

The working group around Dr. Philipp Rathert at the Institute for Biochemistry and Technical Biochemistry investigates the regulation of epigenetic networks of certain cancers and ways of treating them. The working group published its new findings in April.

Microfluidic platform for the best possible cancer therapy

Every tumour and every patient is different, and there are individual reactions to drugs as well as the problem of resistance. Patient-specific cancer treatments require innovative and cost-effective approaches. The TheraMe! consortium has developed a novel instrument: a combination of microfluidic experiments and mathematical modelling for use in cancer precision medicine to prevent incorrect therapy options.

Toxicologists from the University of Konstanz have found that the protein p53 continuously protects our cells from tumorigenesis by coordinating important metabolic processes that stabilize their genomes.

Pancreatic cancer is one of the deadliest types of cancers in humans. Chemotherapies attack not only the tumor cells but also healthy cells throughout the body. Innovative nanoparticles could be a new approach to treat cancer more precisely. The approach was developed by a research team from the Max Planck Institute (MPI) for Multidisciplinary Sciences, the University Medical Center Göttingen (UMG), and the Karlsruhe Institute of Technology.

Development of anti-tumour agents - 20/03/2023

Targeting the protective shield of cancers

Cancer cells have different mechanisms to help them escape destruction by the immune system. Solid tumours, for example, are often surrounded by a protective layer of lactate, which has a strong immunosuppressive effect. WMT AG from Heidelberg is developing small drug molecules that reduce lactate production and thus make cancer cells vulnerable to immune system attacks.

How do tumors react to a certain therapeutic approach? Knowing this before the start of a therapy would be of enormous value for people suffering from cancer as well as for the doctors treating them. Researchers have now made this very observation possible for the CAR-T cell therapy. This allows us to individually investigate how exactly these tumor cells react to the planned therapy.

Researchers at Heidelberg University Hospital (UKHD), the German Cancer Research Center (DKFZ) and at the National Center for Tumor Diseases (NCT) Heidelberg have demonstrated for the first time that there is a link between the development of colorectal cancer in individuals with Lynch syndrome and the composition of immune cells in the colorectal mucosa.

Certain brain tumors in small children contain cells that develop very similarly to normal brain cells and others that have already developed malignantly, depending on where they are located within the tumor.

Neuroblastoma can spread relentlessly or shrink spontaneously. Scientists from the Hopp Children’s Cancer Center Heidelberg (KiTZ), the German Cancer Research Center (DKFZ), the University of Heidelberg and the National Center for Tumor Diseases (NCT) Heidelberg have shown that some malignant neuroblastomas employ a trick to avoid cell death: they use a special mechanism to lengthen the telomeres at the end of their chromosomes.

Doctors and scientists from the German Cancer Research Center (DKFZ) and from Heidelberg University's Medical Faculty Mannheim have successfully tested a neoantigen-specific transgenic immune cell therapy for malignant brain tumors for the first time using an experimental model in mice.

New method for analysing blood samples - 26/11/2020

It involves personalised monitoring using liquid biopsies in addition to conventional PET/CT examinations. This analysis procedure of blood samples could enable closer monitoring of…

Certain anchor proteins inhibit a key metabolic driver that plays an important role in cancer and developmental brain disorders. Scientists from the German Cancer Research Center (DKFZ) and the University of Innsbruck, together with a Europe-wide research network, discovered this molecular mechanism, which could open up new opportunities for personalized therapies for cancer and neuronal diseases. They published their results in the journal Cell.

Tumor vaccines can help the body fight cancer. Mutations in the tumor genome often lead to protein changes that are typical of cancer. A vaccine can alert the patients' immune system to these mutated proteins. For the first time, physicians and cancer researchers from Heidelberg and Mannheim have now carried out a clinical trial to test a mutation-specific vaccine against malignant brain tumors.

Researchers use epigenetic factors to investigate the role of stress in the development of tumor diseases. Experts believe that stress plays a major role in the development of tumors. One occupational group, for example, that experiences extreme stress over a short period of time is astronauts.

Chronic myeloid leukemia (CML) is a type of blood cancer that arises from malignant changes in blood-forming cells of the bone marrow. It mainly occurs in older individuals and represents about 20 percent of all adult leukemia cases. A research team from the Institute of Molecular Medicine and Cell Research at the University of Freiburg has now demonstrated for the first time that mast cells play a crucial role in the development of CML.
