Summary

This study allows head and neck cancer surgeons to specifically visualize cancerous cells apart from normal healthy tissue. 5-aminolevulinic acid (5-ALA) is a safe and effective FDA-approved agent successfully used by neurosurgeons for FGS of different brain tumors is given to the patients preoperatively. Using specific wavelengths of light as well as specialized magnified lenses the surgeons use this technique to assist in tumor resection.

Conditions

Interventions

DRUG

5-Aminolevulinic acid Hydrochloride

The closure consists of colorless glass vial (Type II, Ph Eur) and bromobutyl-rubber stopper ø 20 mm (Type I, Ph Eur) and flip cap. The powder for oral solution is intended for single (partial) use. To prepare the ready-to-use solution the content of one vial is dissolved in 50 ml of water or apple juice. The concentration of the reconstituted solution is 3%. Gleolan® is administered orally to patients prior to tumor removal by surgery (20 mg/kg BW). The reconstituted solution may be prepared up to 24 hours prior to use if protected from light. It should be given 3 hours (range 3-5 hours) prior to planned induction of anesthesia for surgery, although its effect is present for up to 8-12 hours. This step is critical for an optimal visualization of tumor tissue due to pharmacokinetic properties of Gleolan®.
