Fertility preservation for patients with hematologic malignancies: The Korean Society for Fertility Preservation clinical guidelines

Fertility preservation in hematological cancer patients

Among adolescents and young adults, hematological malignancies are the most common malignancies. Although the survival rate of hematological malignancies in young patients has been dramatically improved, due to the continuous improvement and development of tumor diagnosis and treatment options, cytotoxic therapies can significantly reduce a patient's reproductive capacity and cause irreversible infertility. The most two established solutions are embryo cryopreservation and oocyte cryopreservation which can be considered in single female. Sperm or testicular tissue cryopreservation in adult male are feasible approaches that must be considered before gonadotoxic therapy. A comprehensive consultation with reproductive specialists when once diagnosed is a significantly issue which would help those survivors who want to have children. In this article, we review germ cell toxicity, which happens during the treatment of hematological malignancies, and aims to propose safety, efficacy fertility preservation methods in younger patients with hematological malignancies.

Women's Sexual Dysfunctions Following Stem Cell Transplant and the Impact on Couple Relationship

Stem cell transplant proved its efficacy in increasing the survival rate among young patients diagnosed with hematological malignancies. A transplant conditioning regimen is particularly destructive on the genital system, often determining premature ovarian failure, accompanied by vulvovaginal atrophy and sexual dysfunctions. The aims of the present study were, first, to evaluate sexual dysfunctions among transplanted women, using clinical examination and the female sexual function index (FSFI), and second, to determine their impact on a couple's relationship. A prospective observational comparative study was performed and included 38 patients who underwent allogenic stem cell transplant (SCT) procedures for different hematological malignancies and 38 healthy patients (control group). This study included baseline evaluation, one-year, and three-year follow-up visits. In addition to anamnesis and medically obtained information, FSFI was evaluated to determine the impact of gynecological damage in a subjective manner. In the study group, vulvovaginal atrophy was diagnosed in 76.32%, with subsequent sexual dysfunctions in 92.10% of patients, based on FSFI scoring. Even though the results improved throughout the study, at the last visit, mild vulvovaginal atrophy was diagnosed in 81.58% of patients, and the FSFI score was abnormal for 21.05%. When compared to the control group, both sexual dysfunctions and FSFI results were considerably impaired, with statistical significance. There is a confirmed negative impact of sexual dysfunctions and self-declared FSFI on couple/marital status and couple relationships, with statistical significance, at the last visit. In conclusion, anatomical, functional, and psychological difficulties are a reality of long-term survivors after a stem cell transplant. They should be addressed and assessed equally to other medical conditions, as they may determine serious consequences and impact the sexual quality of life and the couple's relationship.

Fertility preservation immediately after therapeutic abortion results in multiple normal follicular growth with the absence of mature oocytes due to early luteinization: a case report and literature review

Cancer therapy has priority over fertility preservation. The time available for fertility preservation in patients with cancer is often very limited and depends on the condition of the underlying disease. This case report presents the results of two rounds of controlled ovarian stimulations (COSs) performed after an induced abortion. The patient had mixed phenotype acute leukemia diagnosed during early pregnancy and underwent a surgical abortion, followed by ovarian stimulation using urinary follicle-stimulating hormone (uFSH) and gonadotropin-releasing hormone (GnRH) agonists. Oocyte retrieval was subsequently performed for oocyte cryopreservation. Despite good hormonal and ultrasonic follicular growth, no oocytes were obtained. During a second COS performed at a low human chorionic gonadotropin (hCG) level (less than 100 IU/L), several mature oocytes were obtained, suggesting that higher hCG levels during COS induce the absence of mature oocytes during normal follicular growth. It is recommended to start COS post-abortion after confirming a low hCG level while considering the timing of cancer treatment.

Investigation of Each Society for Fertility Preservation in Asia

Fertility preservation (FP) remains a future direction for reproductive medicine. FP development is needed to keep up with advancements in other areas of medicine, such as cancer research that has successfully prolonged patients' survival. The demand for optimum FP is sought by both patients and practitioners alike. The American Society of Clinical Oncology has published and updated several FP guidelines. However, these guidelines need to be optimized for each country due to the nature of FP that interacts with the local policy, social decorum, and economic factors. Furthermore, the availability and success rate for each procedure might differ since there is a requirement for advanced and innovative technologies involved in FP. These guidelines should ideally be supported by the FP society to overcome unique barriers that may arise in each country. Here we try to illustrate the most recent update on the condition of FP practice in several countries in Asia. This hopefully will encourage future FP development and might become a useful reference for other countries, especially in Asia.
