A challenge of fertility preservation in the setting of cervical cancer - a clinical case
Abstract
The issue of fertility preservation in patients with cervical cancer is getting more and more common considering the improved effectiveness of early diagnosis and treatment of cancer. There is a number of evidence-based tactics available to the patients with diagnosed cervical cancer. These tactics have been proved effective and include methods such as ovarian transposition; oocyte, embryo and ovarian tissue cryopreservation. Nonetheless, there are no existing medical algorithms to define the priority of actions that should be taken in such cases of restricted time. The objective of this clinical case report is to highlight an existing concern towards the decision-making process regarding fertility preservation in patients with cervical cancer.In this paper we report a clinical case of fertility preservation tactics in a patient undergone ovarian transposition. We pay attention to particular features of the controlled ovarian stimulation (COS) and oocyte retrieval process typical for such patients. The article discusses the subject of COS and oocyte retrieval effectiveness compared to patients who did not undergo ovarian transposition. The 35-year old patient presented 9 month after ovarian transposition to perform oocyte cryopreservation. As a result of COS 3 oocytes were aspirated, compared to 20 oocytes in another patient of comparable age and medical history, but with no ovarian transposition performed.Regarding particular conditions constraining ovarian stimulation and oocyte retrieval after ovarian transposition, we recommend to consider the possibility of performing oocyte/embryo cryopreservation before ovarian transposition in patients with cervical cancer. Prioritizing oocyte and embryo cryopreservation in case of having sufficient time before treatment could significantly improve possibilities of achieving genetically related offspring in a long-term perspective.
