What is Immunotherapy?
Our immune system protects us every day from pathogens like viruses or bacteria. However, cancer cells often escape this defense mechanism – they disguise themselves or specifically suppress the body’s immune response. This is where immunotherapy comes into play: it supports the immune system in recognizing and specifically fighting cancer cells.
Unlike chemotherapy, which attacks all rapidly dividing cells indiscriminately, including healthy ones, immunotherapy is more targeted. It strengthens the body’s own defenses and specifically activates them against tumor cells.
How Does Immunotherapy Work?
Immunotherapy is an umbrella term for various treatment approaches, all pursuing a common goal: to support the body in the fight against cancer.
The type of immunotherapy used depends on several factors – including the type and stage of cancer, as well as the patient’s state of health.
Treatment Forms
Checkpoint Inhibitors
These drugs lift the natural “brakes” in the immune system, which are exploited by cancer cells to stay undetected. By doing so, immune cells can become active again.
CAR-T Cell Therapy
Here, certain immune cells (T cells) are genetically modified so that they can specifically seek out and destroy cancer cells.
Tumor Vaccines (Cancer Vaccines)
These vaccines, currently in development, specifically train the immune system to recognize features of certain tumors – with the goal of triggering a targeted immune response.
Innovation Through Research
Just a few decades ago, cancer was often a death sentence. Today, research and new therapies provide promising opportunities. Immunotherapy is an example of how scientific progress can directly save lives. The Federal Office of Public Health (FOPH/BAG) also emphasizes the importance of personalized medicine – therapies tailored precisely to the individual (2). The Federal Ministry of Education and Research in Germany (BMBF) even calls immunotherapy “one of the most promising fields of modern medicine” and sees it as a fixed part of the national cancer strategy (1).
Successes and Outlook
Many patients with skin cancer, lung cancer, or certain blood cancers already benefit from immunotherapies today. Studies show that some have even been permanently cured – a breakthrough that would have been unthinkable 20 years ago (3).
Research continues: In Germany, Switzerland, and internationally, researchers are working to make immunotherapies even better, safer, and available for more types of cancer.
Why It Concerns Us All
Research is expensive – but the benefit to society is enormous. Every new therapy saves lives, reduces suffering, and ultimately also lowers health care costs. That is why it is important that government institutions like the BMBF in Germany or the State Secretariat for Education, Research and Innovation (SERI)(4) in Switzerland continue to invest in medical research.
Conclusion
Immunotherapy is not a miracle cure – but it is a beacon of hope. Thanks to intensive research, many people today can hope for a longer and healthier life. Every euro invested in research is a step toward the future.
