Analyzing long-term survivors of aggressive solid tumors

Analyzing and Solving Exceptional Long-term Survivors in Solid Tumors With Poor Prognosis: A 3 Cohorts Case Control Matched Study

Observational Cure 51 · NCT06160596

This study looks at patients who have survived much longer than expected from aggressive solid tumors to see what makes them different and if it can help develop new treatments.

What this trial studies

This observational study aims to explore the characteristics of exceptional long-term survivors of solid tumors with poor prognosis, including pancreatic adenocarcinoma, glioblastoma IDH-wildtype, and extensive small-cell lung cancer. It will utilize a retrospective, multi-center approach to collect and analyze clinical records, imaging, and multi-omics data from patients who have survived significantly longer than expected. The goal is to identify biomarkers of resistance and survival that could lead to new therapeutic targets. Advanced technologies, including artificial intelligence, will be employed to interpret the complex data generated from these analyses.

Who should consider this trial

Good fit: Ideal candidates are adult patients aged 18 and older who have survived more than 5 years with metastatic pancreatic ductal adenocarcinoma or extensive small-cell lung cancer, or more than 3 years with glioblastoma IDH-wildtype.

Not a fit: Patients who do not meet the long-term survival criteria or those with other types of tumors will likely not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to the discovery of new therapeutic targets that improve treatment outcomes for patients with aggressive solid tumors.

How similar studies have performed: While this approach is innovative, similar studies have shown promise in identifying biomarkers in cancer, suggesting potential for success.

FOR SURVIVORS

* To be eligible the exceptional survivor patients must fulfill the following inclusion criteria:

  1. Adult patient (≥18 years old at diagnosis).
  2. Three distinct cohorts, one of patients harbouring metastatic pancreatic ductal adenocarcinoma, glioblastoma IDHwt, extensive small cell lung cancer.
  3. Long-term survival is defined as an exceptionally long survival ≥ 5 years from stage IV diagnosis for PDAC, extensive SCLC, and ≥ 3 years for GBM-IDHwt.
