Low Grade Dysplasia Oral Cavity clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Diagnostics for the Treatment of Progressive Mucosal Lesions of the Oral Cavity: a Prospective Study

Start date: n/a
Phase: N/A
Study type: Interventional

Despite improvements in therapy, head and neck carcinomas still have a poor prognosis with a 5-year survival of ~ 50%. Malignancies of the head and neck area are (almost) always preceded by precursor lesions. Treatment of these premalignant mucosal abnormalities is generally limited and not very inconvenient for the patient. If this precursor lesion remain untreated, it may develop into a malignancy of the head and neck. Extensive treatment will be necessary. This means loss of function of the mouth, eg chewing, speaking and swallowing. The hypothesis is that chromosomal instability (CIN) detected by fluorescence is situ hybridization (FISH) is a reliable indicator for progression to malignancy. By intensifying the follow up and treatment in premalignant CIN lesions, the incidence of progression to invasive carcinoma is expected to be significantly reduced. If this hypothesis is justified, there will be a place for CIN detection as a risk indicator in the diagnostic work up of premalignant lesions in the head and neck. The investigators second hypothesis is that loss of heterozygosity (LOH) detected bij DNA markers is a reliable indicator for progression to malignancy. By intensifying the outpatient clinic follow up and treatment in premalignant lesions, the incidence of progression to invasive carcinoma is expected to be significantly reduced. If this hypothesis is justified, there will be a place for CIN and LOH detection as a risk indicator in the diagnostic work up of premalignant lesions in the head and neck.
