The goal of this observational study is to evaluate disease-free survival (DFS) in patients with malignant gliomas undergoing neurosurgical procedures using 5-aminolevulinic acid (5-ALA)-based photodynamic therapy
The investigators are proposing a study that provides descriptive understanding of patients with High-Grade Gliomas in Ecuador. The primary objective of this pilot study is to lay the foundations for the development of a multicenter registry patients with malignant gliomas undergoing neurosurgical procedures using 5-aminolevulinic acid (5-ALA)-based photodynamic therapy, which will provide high-quality real data and serve as a basis for the application to future projects and elaboration of public policies in the medium and long term.

| 5-Aminolevulinic Acid (5-ALA) Gliolan® | Drug | Gliolan® is presented as a powder for oral solution in 60 ml colorless glass vials and is administered orally three hours (range 2-4 hours) before anaesthesia. One bottle contains 1.17 g of 5-aminolevulinic acid (5-ALA), corresponding to 1.5 g 5-aminolevulinic acid hydrochloride (5-ALA HCl). The recommended dose is 20 mg 5-ALA HCl per kilogram body weight. One ml of reconstituted solution contains 23.4 mg of 5-ALA, corresponding to 30 mg 5-ALA HCl. |

Tumor samples

| Fluorescence-Guided Surgery using 5-aminolevulinic acid (5-ALA) | Procedure | During the surgical exploration of the glioma, the neurosurgeon will attempt to identify the mass. The location of the tumor will be assessed using the blue-light filtered microscope. A biopsy of the fluorescent region will be taken to confirm the glioma subtype. The tumor will then be maximally resected. |
|
The questionnaire provides an additional set of disease-specific questions pertaining to brain neoplasms. It consists of 46 items that refer to general issues of quality of life and specific to tumor location. Possible scores range from 0 to 108, with higher scores indicating better quality of life.
| 36 months |
| Average length of hospital stay (ALOS) | The average length of stay in hospitals is often used as an indicator of efficiency. The ALOS refers to the average number of days that patients spend in hospital after surgery. It is calculated by dividing the number of bed-days by the number of discharges after procedure. Average length of stay range from 1 day to 4.5 days. Longer than average stays are usually a symptom of poor communication, quality of care, and effectiveness of treatment. | 36 months |
