How does Immunotherapy work for Mouth Cancer?
Introduction:
Receiving a diagnosis of mouth cancer is challenging, but medical science has advanced significantly. Today, Immunotherapy offers a revolutionary way to treat oral cancer, especially in advanced stages.
Dr. Pratik Patil, a renowned Mouth Cancer Specialist in Pune, is dedicated to bringing these modern treatments to his patients. With 14 years of experience, he is widely trusted as the Best Cancer Specialist for his expertise and compassionate care.
In this blog, we simplify how Immunotherapy works to “wake up” your body’s natural defense system to fight cancer cells effectively.
Why the immune system fails in mouth cancer?
Your immune system is designed to find and destroy abnormal cells. But cancer cells are smart — they hide from the immune system by using a “brake system” called PD-1 / PD-L1.
Mouth cancer cells express PD-L1, which tells immune cells:
- “Don’t attack me – I am normal.”
- This switches off cancer-killing T-cells.
What immunotherapy does?
Immunotherapy drugs remove this brake.
The main drugs used in oral cancer are:
- Pembrolizumab
- Nivolumab
- Serplulimab
- Tislelizumab
They are called PD-1 inhibitors. They:
- Block the PD-1 signal
- Wake up immune T-cells
- Allow them to recognize and kill cancer cells
- So instead of killing cancer directly (like chemotherapy),
- immunotherapy trains your own immune system to do the job.
Why it works especially well in mouth cancer?
Oral cancers usually:
- Are caused by tobacco, alcohol, or HPV
- Have many genetic mutations
These mutations make the cancer look more “foreign” to the immune system —
which makes immunotherapy more effective.
Who benefits the most?
Immunotherapy works best in:
- Advanced or metastatic mouth cancer
- Recurrent disease after chemotherapy
- Tumors with high PD-L1
- HPV-positive oral cancers
Conclusion:
Immunotherapy has transformed the way we treat advanced oral cancer, offering new hope where traditional methods may have limitations. However, every patient’s case is unique, and personalized medical advice is essential.

FAQ's About How Immunotherapy work for Mouth Cancer?
Immunotherapy is highly effective for many patients, with success rates (significant tumor shrinkage) ranging from 15% to 36%. It is known for providing "durable responses," meaning patients who respond often stay cancer-free or stable for much longer than with traditional chemotherapy.
Immunotherapy is now a standard advanced treatment in India, with FDA-approved drugs like Pembrolizumab and Nivolumab widely available. In cities like Pune, it is offered at specialized centers like Jupiter Hospital, Baner, providing world-class care at a fraction of the cost found in Western countries.
It is primarily used for advanced, recurrent, or metastatic mouth cancer that has spread or returned after initial treatment. It is also increasingly used as "neoadjuvant" therapy before surgery to shrink tumors and prime the immune system to prevent future recurrence.
While "cure" is a strong word in oncology, immunotherapy can lead to complete remission (no visible cancer) in some patients. For many others, it successfully turns a life-threatening advanced cancer into a manageable chronic condition, significantly extending life expectancy.
