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

Overview

The study aims to test for the presence or absence of primary tumor-specific tumor markers in ovarian tissue. Therefore, there will be a first phase in which pathology-specific markers will be identified in the patients' diagnostic pathological material by histological, immunohistochemical, and molecular analysis; then, tumor markers will be sought in cryopreserved ovarian tissue.

Detailed description

Standardized strategies for detecting neoplastic cells in ovarian tissue of patients with prior sarcomas or oncohematologic malignancies are not available. To increase the safety of ovarian tissue transplantation, the use of advanced and highly sensitive molecular approaches could greatly improve the detection of malignant cells in ovarian tissue.

The study aims to test for the presence or absence of primary tumor-specific tumor markers in ovarian tissue. Therefore, there will be a first phase in which pathology-specific markers will be identified in the patients' diagnostic pathological material by histological, immunohistochemical, and molecular analysis; then, tumor markers will be sought in cryopreserved ovarian tissue.

Identifying highly sensitive molecular tests would lead to increased safety of transplantation in patients cured of sarcomas and oncohematologic diseases. Overall, applications of the techniques under study would increase the chances of resolving infertility, which often reduces the quality of life of these patients, by offering them the chance to procreate and have biological children. The hope of motherhood is an important psychological support and can greatly help patients cope with the difficult treatment process while minimizing social/psychological support. In the long journey of treatment to defeat the disease, being able to offer an option to at least combat the fear of losing endocrine and reproductive function can have a profound impact not only on the patients themselves, but on the entire family and non-family environment.
