Immune and tumor microenvironment biomarkers to guide immunotherapy for advanced digestive and gynecologic cancers

Identification of Innovative Biomarkers Related to the Immune System or Tumor Microenvironment to Promote the Efficacy of Immunotherapies

NA · Centre Hospitalier Universitaire de Besancon · NCT06626269

This project will test whether measuring immune cells and molecules in blood and tumor samples can help predict who with advanced digestive or gynecologic cancers will respond to immunotherapy.

What this trial studies

This interventional protocol collects blood samples and tumor tissue from adults with advanced digestive or gynecologic cancers to profile immune cells, memory lymphocytes, secreted plasma molecules, and features of the tumor microenvironment. Patients are enrolled in cohorts based on cancer type and planned treatment (immunotherapy or chemotherapy/targeted therapy), and samples are analyzed to identify biomarkers that correlate with treatment response or resistance. Analyses include characterization of T cell populations in blood, immunophenotyping of tumor-infiltrating lymphocytes from biopsies or surgical specimens, and measurement of circulating immune-related molecules. Sites include the University Hospital of Besançon and the Georges François Leclerc cancer center in Dijon, France, and findings will be compared with clinical outcomes to identify predictive markers.

Who should consider this trial

Good fit: Adults (≥18) with locally advanced or metastatic digestive or gynecologic cancers who are eligible for immunotherapy or chemo‑immunotherapy, have ECOG 0–2, an investigator-estimated life expectancy >6 months, French social security coverage, and provide informed consent.

Not a fit: Patients without advanced digestive or gynecologic cancers, those not eligible for immunotherapy or chemotherapy as defined by the protocol, or those with poor performance status or very limited life expectancy are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the trial could help clinicians predict which patients will benefit from immunotherapy and tailor treatments to improve outcomes.

How similar studies have performed: Previous studies have identified some predictive immune biomarkers (e.g., PD-L1, TILs, tumor mutational burden) with limited accuracy in various cancers, so this work builds on existing but incomplete evidence.
