Groundbreaking Study: Immunotherapy Extends Survival for Head & Neck Cancer Patients
In an urgent update from the world of oncological research, a monumental international study has shown that the immunotherapy drug pembrolizumab significantly extends disease-free survival for patients with locally advanced, operable squamous epithelial carcinoma in the head and neck area. The findings, published in the prestigious journal “The New England Journal of Medicine,” are expected to set a new standard for cancer treatment.
Study Highlights and Findings
The clinical phase III study involved patients receiving pembrolizumab both pre- and postoperatively in addition to the standard therapy, which includes surgery and subsequent radiation or chemoradiotherapy. Pembrolizumab is an immune checkpoint inhibitor designed to disable mechanisms within the immune system that hinder the body’s ability to combat cancer cells.
The study, conducted at 192 medical centers worldwide, including MedUni Vienna and AKH Vienna, enrolled 714 participants. The results were remarkable: patients in the pembrolizumab group saw their disease-free survival jump from an average of 26.9 months to 59.7 months. According to Thorsten Füreder, a key researcher involved with the study, this effectively doubles the time until relapse or tumor progression.
The Importance of Immunotherapy in Cancer Treatment
Head and neck squamous cell carcinoma (HNSCC) is a particularly challenging form of cancer, often treated with a combination of surgery, radiation, or chemoradiotherapy. Matthias Preusser, head of oncology at MedUni Vienna and AKH Vienna, underscores that these treatments have remained largely unchanged over two decades, making the new findings a significant breakthrough.
“Immunotherapy with pembrolizumab has been used primarily in recurrent or metastatic stages,” Preusser notes. “However, this study confirms its effectiveness before and after surgery, potentially defining a new standard for head and neck tumor treatment.”
Future Implications and Expectations
The researchers anticipate approval for the new therapy in Europe within the next three to four months. This could bring a renewed hope for thousands of patients globally, ushering in a new era in cancer care.
