Scientists hunt for immune clues in rare salivary gland cancers
NCT ID NCT06047236
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is for 300 people with salivary gland tumors (both cancerous and non-cancerous) to learn how the immune system reacts to these rare cancers. Researchers will collect tumor tissue and blood samples before and after treatment to find immune markers that might predict how the disease will progress. The goal is to better understand the disease and pave the way for future immunotherapy treatments.

Inclusion Criteria: 1. Observational group * Initial diagnosis of a primary salivary gland carcinoma in the head and neck region (no squamous cell carcinomas) * Specimen collection from the center of the tumor when the primary tumor is sufficiently large without that the pathological assessment is impaired 2. Control group 1 * Initial diagnosis of a benign salivary gland tumor in the head and neck region * Specimen collection from the center of the tumor when the primary tumor is sufficiently large without that the pathological assessment is impaired 3. Control group 2 * functional diseases of the nose or ear (patients with the indication for functional ear surgery and rhinoplasty) * Specimen collection with sufficiently large resectate during a functional nose surgery for all groups: * Willingness of patients to collect blood, saliva and stool and consent to the preservation of all samples for study purposes. * Age ≥ 18 years * sufficient cognitive ability of the patients to understand the purpose of the study and to understand the purpose of the study and agree to it Exclusion Criteria: * Distant metastasis at the time of diagnosis and simultaneous second cancers, i.e. at study inclusion * Malignancy in the last 5 years regardless of location (except basal cell carcinoma or cis of the uterine cervix) * Carcinomas for which specimen collection is not possible or likely without compromising the compromise the pathological evaluation * Persistent drug or medication abuse * Patients who are unable or unwilling to comply with protocol and to be treated * Patients who are represented by a legal guardian * Patients who are not suitable for participation in the study due to a language barrier
