Transplanting cryopreserved ovarian tissue in cancer survivors

Safety Assessment Of Cryopreserved Ovarian Tissue Transplantation In Patients Who Have Survived Sarcomas And Hematological Tumors

Not applicable Interventional IRCCS Azienda Ospedaliero-Universitaria di Bologna · NCT06829654

This study is testing whether ovarian tissue from cancer survivors is safe to transplant by checking for any leftover cancer cells, which could help restore their fertility.

What this trial studies

This study investigates the presence of tumor-specific markers in ovarian tissue from patients who have survived sarcomas and hematological malignancies. It involves identifying these markers through advanced histological, immunohistochemical, and molecular analyses of patients' diagnostic materials. The goal is to enhance the safety of ovarian tissue transplantation by ensuring that malignant cells are not present in the cryopreserved tissue. This could ultimately help restore fertility in patients who have undergone cancer treatment.

Who should consider this trial

Good fit: Ideal candidates include patients aged 18 to 38 who have survived specific types of sarcomas or hematological malignancies and have consented to the procedure.

Not a fit: Patients who are older than 38 or those who do not have cryopreserved ovarian tissue may not benefit from this study.

Why it matters

Potential benefit: If successful, this could provide cancer survivors with a safe option to restore fertility and have biological children.

How similar studies have performed: Other studies have shown promise in using similar advanced molecular techniques for detecting malignant cells in ovarian tissue, indicating potential success for this approach.
