          Abstract

          Einleitung

          Die Retransplantation von kryokonserviertem Ovarialgewebe ist eine etablierte Methode zur Wiederherstellung der autologen Hormonproduktion und Rekonstitution der Fertilität nach Strahlen- und/oder Chemotherapie bei Frauen im fertilen Alter und führte weltweit bisher zu mehr als 170 Geburten.

          Falldarstellung

          Die 31-jährige Patientin erkrankte im Jahr 2013 an einem Adenokarzinom der Cervix uteri, pT1b1V0L0. Im Jänner 2014 erfolgte die erweiterte Hysterektomie mit Lymphknotendissektion und Adnexektomie beidseits, auf Wunsch der Patientin wurde zuvor Ovarialgewebe per Laparoskopie entnommen und kryokonserviert. Bei Rezidivfreiheit von 5 Jahren unter laufender Hormonersatztherapie (HRT) wurde im November 2019 auf Wunsch der Patientin die Retransplantation von 2 Ovargewebestücken entlang der Fascia brachialis des linken Unterarms durchgeführt. Einen Monat nach Retransplantation beendete die Patientin die Einnahme der HRT, 3 Monate danach durch Überprüfung der Gonadotropine und E2-Spiegel eine regelrechte Funktion des retransplantierten Gewebes nachgewiesen werden. Es trat eine deutliche Schwellung im Bereich der Retransplantationsstelle auf, bei einer Ultraschallkontrolle im Mai 2020 konnten 3 vitale Follikel dargestellt werden.

          Schlussfolgerung

          Dies ist die erste erfolgreiche Retransplantation von kryokonserviertem Ovarialgewebe zur Rekonstituierung der autologen Hormonproduktion bei einer Zervixkarzinompatientin in Österreich. Durch Blut‑, Ultraschall- und zytologische Untersuchung, nicht zuletzt aber aufgrund des persönlichen Wohlbefindens der Patientin konnte der Nachweis der Funktionalität des retransplantierten Gewebes auch 6 Monate nach dem Eingriff erbracht werden. Zuletzt möchten wir auf die Wichtigkeit der Information und Beratung junger Patientinnen mit Tumorerkrankungen bezüglich einer Fertilitätsprotektion hinweisen.

          Introduction

          Retransplantation of cryopreserved ovarian tissue has become an established method of restoring autologous hormone production and fertility after radiotherapy and/or chemotherapy for underlying oncological disease in women of reproductive age and has so far led to more than 170 births worldwide.

          Case presentation and course

          In 2013, the 31-year-old patient developed adenocarcinoma of the uterine cervix, pT1b1V0L0. In January 2014, an extended hysterectomy with lymph node dissection and bilateral adnexectomy were performed. At the patient’s request, ovarian tissue was cryopreserved 2 days previously. In November 2019, the retransplantation of two ovarian tissue pieces along the brachial fascia of the left forearm was performed, with no recurrence for 5 years under ongoing hormone replacement therapy (HRT). At 1 month following retransplantation, the patient stopped taking HRT, and 3 months later proper function of the retransplanted tissue could be demonstrated by checking gonadotropins and E2 levels. There was a clear swelling in the area of the retransplantation site, and three vital follicles could be visualized during an ultrasound examination in May 2020.

          Conclusion

          This is the first successful retransplantation of cryopreserved ovarian tissue to restore autologous hormone production in a cervical cancer patient in Austria. Based on blood, ultrasound and cytological examinations, not to mention the patient’s personal well-being, functionality of the retransplanted tissue could be demonstrated even at 6 months after the procedure. Finally, the authors would like to highlight the importance of informing and consulting young patients with tumor diseases on the various possibilities of fertility preservation.

            American Society of Clinical Oncology recommendations on fertility preservation in cancer patients.

            To develop guidance to practicing oncologists about available fertility preservation methods and related issues in people treated for cancer. An expert panel and a writing committee were formed. The questions to be addressed by the guideline were determined, and a systematic review of the literature from 1987 to 2005 was performed, and included a search of online databases and consultation with content experts. The literature review found many cohort studies, case series, and case reports, but relatively few randomized or definitive trials examining the success and impact of fertility preservation methods in people with cancer. Fertility preservation methods are used infrequently in people with cancer. As part of education and informed consent before cancer therapy, oncologists should address the possibility of infertility with patients treated during their reproductive years and be prepared to discuss possible fertility preservation options or refer appropriate and interested patients to reproductive specialists. Clinician judgment should be employed in the timing of raising this issue, but discussion at the earliest possible opportunity is encouraged. Sperm and embryo cryopreservation are considered standard practice and are widely available; other available fertility preservation methods should be considered investigational and be performed in centers with the necessary expertise. Fertility preservation is often possible in people undergoing treatment for cancer. To preserve the full range of options, fertility preservation approaches should be considered as early as possible during treatment planning.

              Cancer and fertility preservation: international recommendations from an expert meeting

              In the last years, thanks to the improvement in the prognosis of cancer patients, a growing attention has been given to the fertility issues. International guidelines on fertility preservation in cancer patients recommend that physicians discuss, as early as possible, with all patients of reproductive age their risk of infertility from the disease and/or treatment and their interest in having children after cancer, and help with informed fertility preservation decisions. As recommended by the American Society of Clinical Oncology and the European Society for Medical Oncology, sperm cryopreservation and embryo/oocyte cryopreservation are standard strategies for fertility preservations in male and female patients, respectively; other strategies (e.g. pharmacological protection of the gonads and gonadal tissue cryopreservation) are considered experimental techniques. However, since then, new data have become available, and several issues in this field are still controversial and should be addressed by both patients and their treating physicians. In April 2015, physicians with expertise in the field of fertility preservation in cancer patients from several European countries were invited in Genova (Italy) to participate in a workshop on the topic of “cancer and fertility preservation”. A total of ten controversial issues were discussed at the conference. Experts were asked to present an up-to-date review of the literature published on these topics and the presentation of own unpublished data was encouraged. On the basis of the data presented, as well as the expertise of the invited speakers, a total of ten recommendations were discussed and prepared with the aim to help physicians in counseling their young patients interested in fertility preservation. Although there is a great interest in this field, due to the lack of large prospective cohort studies and randomized trials on these topics, the level of evidence is not higher than 3 for most of the recommendations highlighting the need of further research efforts in many areas of this field. The participation to the ongoing registries and prospective studies is crucial to acquire more robust information in order to provide evidence-based recommendations.
