Reducing radicality in fertility-sparing surgery is associated with improved in vitro fertilization outcome in early-stage cervical cancer: A national retrospective study.

OBJECTIVE: Fertility-sparing surgery (FSS) aims to achieve oncological outcomes that are non-inferior to radical treatment while preserving fertility and optimizing reproductive results. This study assesses in vitro fertilization (IVF) outcomes in early-stage cervical cancer survivors following FSS, comparing radical and non-radical approaches. METHODS: This retrospective analysis used data from Hungary's National Health Insurance Fund (2004-2022) on patients who underwent IVF treatment following FSS for early-stage cervical cancer at ten Hungarian fertility clinics. Patients were classified into radical and non-radical surgical groups, with the uterine arteries being spared in the non-radical procedures. RStudio (R software version: 4.2.2) was used for statistical analysis. Student's t-test was used to compare group means, and Fisher's exact test was applied to assess independence and distributions between categorical variables, and to estimate odds. RESULTS: The study analyzed data from 122 IVF treatment cycles involving 36 patients. The non-radical group had a significantly higher live birth rate (83%, 5/6 compared to the radical group (17%, 5/30). Additionally, the non-radical group had a significantly higher implantation rate and cumulative live birth rate per oocyte retrieval (37%, 7/19 and 55%, 6/11 respectively) compared to the radical group (8%, 12/148 and 6%, 5/80 respectively). CONCLUSION: This is the largest study to evaluate IVF outcomes in young cervical cancer survivors who have undergone FSS. The findings suggest that less radical procedures are associated with significantly better IVF outcomes. These results emphasize the importance of considering oncological safety and reproductive outcomes together when choosing FSS for early-stage cervical cancer patients. It also highlights the reproductive benefits of performing less radical surgery.

In Hungary, an average of 2066 women under the age of 40 are diagnosed with cancer each year according to data from the National Cancer Registry. Approximately two-thirds of these patients require gonadotoxic treatment for their disease, which could potentially reduce their chances of future conception and childbirth. Currently, there are no professional guidelines on fertility preservation in Hungary, however, it is important to inform patients about their options. In our previous paper, we presented the gonadotoxic effects of oncotherapies and the currently available fertility preservation techniques. This second paper provides current treatment methods and recommends fertility preservation techniques in different cancer types. The success of an oncofertility program relies heavily on the effective communication and collaboration between oncologists and reproductive specialists involved in fertility preservation. This paper may be the first step in elaborating a guideline towards improving access to oncofertility services and ultimately improving the quality of life for young cancer survivors in Hungary.

The incidence of cancer increases with age and as family planning is being delayed, there is a growing number of cancer patients whose fertility may be affected by oncological treatments. International guidelines recommend that all reproductive age cancer patients, including adolescent patients, should be referred for fertility preservation consultation, and if necessary, fertility preservation procedures should be performed. Fertility preservation enables cancer survivors to offer a chance for biological parenthood after recovery. In this review, the gonadotoxic effects of oncological therapies and the fertility preservation possibilities for female cancer patients based on international recommendations and literature are discussed. Our next review will provide detailed information on the special fertility preservation possibilities for different cancer types. The two reviews may help to elaborate a national guidance.

Introduction: Fertility preservation or oncofertility is a relatively new interdisciplinary field dealing with the preservation of female and male reproductive functions before the administration of gonadotoxic therapy. Despite recommendations from different international scientific bodies, Hungary still does not have a national fertility preservation network, patient referral is unorganised. Objective: As the first step towards establishing a national fertility preservation program, a study was designed to evaluate the Hungarian oncologists' knowledge, attitudes and practice in the field of oncofertility. Method: A national online survey was sent to the physician members of the Hungarian Society of Clinical Oncology between November 2020 and February 2021. The survey was completed by 94 physicians and the results were analysed statistically. Results: The majority of the oncologists (77%) discusses reproductive health issues before starting gonadotoxic therapy. However, almost half of these physicians do not refer patients for fertility preservation consultation or treatment. Physicians report lack of organised fertility preservation network, lack of knowledge and clinical practice guidelines as major barriers in referring their patients for fertility preservation. The majority (86%) proposes that a better col-laboration between cancer and fertility centers needs to be organized in Hungary. Conclusion: This study is the first nationwide survey to assess oncologists' attitude, knowledge and practice in the field of oncofertility in Hungary. It highlights the need for more education and increased collaboration between oncologists and reproductive specialists. This is an important step towards the establishment of a national fertility preservation network which is our ultimate goal.

Live births after in vitro maturation of oocytes in women who had suffered adnexal torsion and unilateral oophorectomy following conventional ovarian stimulation.

PURPOSE: To report the first successful application of in vitro maturation (IVM) of oocytes resulting in live births in two anovulatory women who had suffered oophorectomy following ovarian torsion after stimulation with gonadotropins. METHODS: Data abstraction was performed from medical records of two subfertile women with excessive functional ovarian reserve. Both women had previously received gonadotropins for ovulation induction or ovarian stimulation, resulting in ovarian torsion. They were offered IVM of oocytes retrieved from antral follicles after mild ovarian stimulation, insemination of mature oocytes using ICSI, and embryo transfer. Outcome measures were the incidence of complications and live birth after fertility treatment. RESULTS: Transvaginal retrieval of cumulus-oocyte complexes from a unique ovary was conducted. One patient had a singleton live birth after vitrified-warmed embryo transfer in the second IVM cycle. The other patient had a singleton live birth after transfer of a fresh blastocyst in her first IVM cycle. CONCLUSIONS: Although approaches have been developed to prevent ovarian hyperstimulation syndrome (OHSS) and to increase the safety profile of fertility treatment in predicted high responders, women with an excessive functional ovarian reserve may have a non-negligible risk of ovarian torsion. For these patients, IVM should be considered as a safer alternative approach.
