Impact of Pesticide Exposure on Survival and Tumor Aggressiveness in Patients With Glioblastoma: A Prospective Clinical Study (EXPOGLIO)
This prospective, interventional, monocentric study will aim at investigating the relationship between pesticide exposure and the treatment response of patients with GBM.
The study will be conducted on a population of 120 participants aged over 18 years, diagnosed with IDH wild-type GBM, and who will receive the treatment for GBM (by, where applicable, concomitant radiochemotherapy or chemotherapy in combination with targeted therapy).
The recruitment period will last 2 years. After eligibility is confirmed, study assessments will be performed at the baseline visit (i.e. before GBM treatment initiation). The study specific assessments consist of: biological sample collection (urine, hair and blood) and completion of a self-reported questionnaire.
The questionnaire will entail 2 parts: i- the main part delivered to all participants, ii- an optional part delivered only when a professional pesticide exposure is suspected (based on answers provided in part 1).
Then, the patient will be followed up for about 3 years (or 6 timepoints) for data collection. During this period, data collection will take place twice a year according to the routine visits at the investigator site for clinical benefit assessment to document tumor response, survival status and further anti-cancer treatments if applicable. This data is routinely captured in patient's medical records per SOC and will not require study specific visits.
The follow-up period might differ between patients as it will depend on the routine visit schedule. This schedule will be set up for each patient specifically according to their SOC.

상세 설명
The study assessments entail: biological sample collection and self-reported questionnaire completion.
- After the biological sample (urine and hair) collection, samples will be transfered to the Limoges Hospital for analysis (detection of pesticides residus and metabolites).
- After the optional blood sample collection, samples will be processed (Peripheral Blood Mononuclear Cell isolation) and stored at the sponsor site for constitution of a biobank (plasma and PBMC).
- The data pertaining to the self-reported questionnaires will be transfered to the INSERM team in Bordeaux for epidemiology analysis. The resulting Pesticides Exposure Scores will be integrated in the clinical database. No patient confidential information will be retained by the sub-contracting INSERM team after the end of the study.

At the baseline visit, the following biological sample collection will be carried out:
At the baseline visit, the patient will be handed a blank copy of the questionnaire to be completed at home.
The patient will be asked to return the completed questionnaire within 1 month.
Within two weeks of receipt, a member of the investigator staff will review the questionnaire for completeness and consistency and if necessary will make a follow-up phone call to the patient for clarification.
If, based on the patient answers, a suspicion of occupational pesticide exposure is identified, the patient will be provided with a second part of the questionnaire in order to enhance the granularity of the answers.
The patient will be given one month to return the questionnaire part 2 to the site staff.
Within two weeks of receipt of the second part of the questionnaire, a member of the investigator staff will review it and contact the patient if necessary (see questionnaire part 1) The questionnaire part 1 should take about 1h and the part 2 about 30 minutes to fill out.

PFS is defined as the time from inclusion until progression (according to the investigator's judgment) or death.
Patients alive without documented progression at last-follow-up news will be censored at this date.

OS is defined as the time from inclusion to death from any cause.
At the time of analysis, patients alive will be censored at the date of last follow-up news.

Pesticide Exposure
기간: through study completion, an average of 5 years
|
Exposure to pesticides will be defined using the self-reported standardized questionnaire (derived from CERENAT study).
Three types of exposition will be defined (professional, environmental and domestic) and different metrics will be derived from the questionnaire (probability, intensity…).
