Tumor organoids from undifferentiated primary carcinomas to guide treatment choices

Development of Tumor Organoids From Undifferentiated Primary Carcinomas to Guide Therapeutic Decisions

Centre Francois Baclesse · NCT06612827

This project will grow tumor organoids from patients with undifferentiated primary carcinomas to try to predict which treatments might work best for them.

What this trial studies

This observational project collects tumor and blood samples from adults with histologically confirmed undifferentiated primary carcinoma who are starting first‑line systemic therapy (or have received up to two cycles). Laboratory teams will attempt to establish patient‑derived tumoroids and run functional drug sensitivity tests to compare with patients' clinical responses. The approach aims to create a living biobank and to explore whether tumoroid testing can inform future treatment decisions. The work is conducted at a single center, Centre François Baclesse in Caen, France.

Who should consider this trial

Good fit: Adults with histological and immunohistochemical confirmation of undifferentiated primary carcinoma who are eligible for first‑line systemic treatment, have a life expectancy over three months, and can give informed consent.

Not a fit: People who are pregnant or breastfeeding, legally incapacitated, have a very short life expectancy, or whose tumor samples fail to form organoids are unlikely to gain benefit from the approach.

Why it matters

Potential benefit: If successful, the approach could help clinicians choose more effective therapies by testing drugs on a patient’s own tumor cells before giving treatment.

How similar studies have performed: Organoid‑based testing has shown promising ability to predict drug response in several cancer types in early studies, but it is not yet a standard clinical tool.
