AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for girls and young women with cancer, or with another illness or treatment that may harm their fertility. Ovarian tissue is frozen to preserve fertility.

Age
The registry lists 12 Years to 18 Years, while the criteria text says 0-35 years old.
Sex
Female only.
Disease stage
Diagnosed with cancer, for example leukaemia, lymphoma, bone tumours, neurological neoplasms or sarcoma; or an illness or treatment that may cause irreversible damage to fertility.

Main reasons for not taking part

  • No anticipated oncologic therapies
  • Pregnant
  • Children with one ovary
  • Children deemed high risk for perioperative complications
  • Unable to provide consent or assent

Who can take part

  • Patients aged from 0-35 years old and diagnosed with cancer e.g., leukaemia, myeloproliferative or myelodysplastic diseases, lymphoma, bone tumours, neurological neoplasms and sarcoma, Paediatric bone marrow transplant patients
  • Patients with any illness or who will undergo any type of treatment that may cause irreversible damage to their fertility, such as extensive abdominal surgery, high toxicity medication and treatments
  • Patients suffering from hormone-sensitive malignancies who will undergo medical treatment, such as radiotherapy and chemotherapy that is liable to damage their ovaries and deter them from conception in the future

Who cannot take part

  • Patients with no anticipated oncologic therapies Patients who are pregnant Children with one ovary Children deemed high risk for perioperative complications Patients unable to provide consent/assent (i.e. significant psychiatric problems/cognitive delay)

About the trial

What the trial wants to find out

Ovarian tissue freezing is an ideal option for these patients as it can be performed immediately and does not need any time for ovarian stimulation. We hope we can develop this service in our locality to allow more young female cancer patients to have their fertility preserved.

The group in the trial

  • ovarian tissue freezing and subsequent auto-transplantation after thawingTreatment being tested

    Removal of the ovarian tissue will be retrieved via laparoscopic surgery under general anesthesia. The ovarian cortical tissue obtained will be transferred on ice to the laboratory for cryopreservation. After medical treatment, if the patient would like to start a family but has experienced premature ovarian failure, she will have ovarian tissue auto-transplantation after thawing.
