Progress in Cancer Care: A Look at Immunotherapy and Therapeutic Vaccines

Today, 75% of French people believe that the care and treatments offered to patients are of very good quality, reports a survey carried out in May 2025 for the 20th anniversary of the National Cancer Institute. While multiple challenges remain, the mortality rate is decreasing for many locations (breast, prostate, colon and rectum, etc.).Advances in the fight against pathology improve the daily lives of patients and their loved ones.

Immunotherapy: A Revolution at All Stages of the Disease

Lung, kidney, or bladder: indications are increasing for immunotherapy, which helps the immune system track down cancer cells. “we no longer think based on the location of the tumor, but on its molecular target. This allows us to personalize treatments“, specifies Muriel Dahan, director of research at Unicancer. Long reserved for last resorts, immunotherapy is now offered earlier, sometimes even before surgery, when the patient’s defenses are still strong. This results in avoided relapses, prolonged survival, and even words that were once rarely spoken: remission, or even cure. The most widely used strategy is that of “anti-checkpoints” – drugs that “take off the brakes” on the immune system – but others are emerging: vaccines, modified cells, or oncolytic viruses, capable of destroying cancer cells while awakening immunity. A double attack already tested,notably in melanoma.

Therapeutic Vaccine: A New Way to Combat Relapses

What if the immune system learned to recognize a tumor, as it does a virus? This is the challenge of therapeutic vaccines, currently in the experimental stage. They help the body defend itself against a tumor already present. To do this,they stimulate the immune system to identify and destroy cancer cells. These vaccines differ from preventative vaccines (like those for HPV) which aim to prevent cancer from developing in the first place. The goal of therapeutic vaccines is to treat existing cancer, potentially offering a new line of defense against relapses and improving long-term outcomes.

Key Takeaways

• Immunotherapy is becoming more widely used and is now often administered earlier in the treatment process.
• Anti-checkpoint drugs are a key component of immunotherapy, releasing the brakes on the immune system to fight cancer.
• Therapeutic vaccines are an experimental approach aiming to train the immune system to recognize and destroy existing tumors.
• Personalized medicine, focusing on the molecular targets of tumors, is driving advancements in cancer treatment.

The future of cancer treatment is increasingly focused on harnessing the power of the immune system and tailoring therapies to the individual characteristics of each patient’s cancer.Ongoing research into therapeutic vaccines, combined with the continued development of immunotherapy strategies, holds notable promise for further improving survival rates and quality of life for those affected by this disease. We can anticipate even more refined and effective treatments as our understanding of cancer biology deepens.
