Revolutionary study: New hope in the fight against melanoma!

On May 9, 2025, scientists from the Medical Faculty of the University of Duisburg-Essen will intensively examine relapses in patients suffering from melanoma after immunotherapy. This research project is led by Prof. Dr. Florian Rambow and Dr. Georg Lodde and was recently funded by the German Cancer Aid with 530,000 euros over two years, starting in March 2025. The overall aim of the study is to better understand the risk of recurrences (return of melanoma), especially with regard to the histological and molecular environment of the primary tumor.

What is particularly noteworthy is that in an initial study, patients suffered earlier relapses despite receiving immunotherapy than was reported in clinical studies. These findings come from a comprehensive analysis of a large group of patients who were followed for more than four years at various skin tumor centers in Germany. The research team is now carrying out high-resolution single-cell analyzes on treatment-naïve tissue from both primary tumors and metastases. This combination of clinical data and tumor tissue makes the study cohort unique worldwide.

Aims of the research

The central goals of this research are to identify new drug targets to overcome resistance to PD-1 inhibitors. PD-1 inhibitors are crucial for supporting the immune system because they block the protective mechanism of cancer cells. However, despite their great potential, it is necessary to further develop the effectiveness of these inhibitors so that they can become even more effective in clinical treatment. Immunotherapy is increasingly recognized as the fourth pillar of cancer treatment, alongside surgery, chemotherapy and radiation therapy reports the US National Library of Medicine.

Research on anti-PD-1 drugs has established itself as a promising new field of development and aims to provide new insights into the role and mechanism of PD-1 combination therapy in tumor control. One goal of the current studies is to promote clinical application in anti-tumor immunotherapy. To this end, the mechanisms through which PD-1 and its ligand PD-L1 act must be further researched in order to successfully overcome tumor immunosuppression.

In the long term, research should make a significant contribution to making melanoma therapy more effective and significantly increasing the chances of success for affected patients.

In summary, the study provides a comprehensive look at relapses in melanoma under immunotherapy and promises innovative approaches to improving treatment options announces the University of Duisburg-Essen. These developments could revolutionize not only the research community but also clinical practice.
