Se trata del primer caso de nacimiento con vida tras el éxito del trasplante de un fragmento de ovarios tomados de la paciente y luego congelados, antes del inicio de la quimioterapia, según un procedimiento denominado "autotrasplante ortotópico".
Según el principal autor, el profesor Jacques Donnez, de la Universidad Católica de Lovaina (Bélgica), este resultado "abre nuevas perspectivas para las jóvenes pacientes que enfrentan una insuficiencia ovárica precoz", o menopausia precoz, producto de una quimioterapia o radioterapia, que anula toda posibilidad de embarazo.
"La crioconservación deberá ser propuesta a todas las mujeres jóvenes a las que se les diagnostique un cáncer, junto con las otras opciones factibles para preservar su fertilidad", añadió.
La paciente pudo tener su hijo siete años después de la puesta en conservación de sus tejidos ováricos, antes de comenzar el tratamiento para un linfoma de Hodgkin. Así, pese a que la terapia anticancerosa la volvió infértil, la paciente pudo tener de nuevo ciclos menstruales, con ovulación, cinco meses después del transplante. Once meses después del autotransplante, quedó encinta por fecundación natural.
