Evaluating a new surgical technique for identifying cancer origins in the oropharynx

Evaluation of the Role of Tongue Base MucOsectomy and Step sErial Sectioning in the Management of the Unknown Primary Squamous Cell Cancer in the Head and Neck

Observational Royal Marsden NHS Foundation Trust · NCT04151134

This study is testing a new surgery to see if removing tissue from the back of the tongue can help find the original source of cancer in patients with oropharyngeal squamous cell carcinoma.

What this trial studies

This observational study focuses on patients with squamous cell carcinoma (SCC) of the oropharynx, particularly those with cervical metastases and unknown primary sites. It employs a surgical technique called tongue base mucosectomy (TBM) to remove tissue from the back of the tongue for analysis. The goal is to determine if the primary cancer is contained within this tissue, which could aid in better diagnosis and treatment planning. The study will also utilize step serial sectioning histological processing to examine the removed tissue.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 16 or older with confirmed cervical metastatic SCC who are undergoing TBM.

Not a fit: Patients who have already identified their primary cancer site or have a history of previous head and neck cancers may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved identification of cancer origins, allowing for more targeted and effective treatment options for patients.

How similar studies have performed: While this specific approach is relatively novel, similar studies have shown promise in identifying unknown primary cancers in other regions, suggesting potential for success.
