Sperm cryopreservation: Clinical and fertility outcomes in male oncological patients with germ cell tumors or hematological disorders.

ABSTRACT:

Purpose

There is insufficient understanding of the effects of malignant diseases themselves and chemotherapy on semen quality and final fertility outcomes. Here, the authors focused on the patients with malignant diseases who cryopreserved sperm pre- or post-chemotherapy for future fertility, and revealed how clinical settings can affect semen quality and final outcomes.

Methods

The authors reviewed the records of 257 patients with malignant diseases who cryopreserved sperm. Among 257 cases, 113 men with germ cell tumors (GCTs) and 111 men with hematological disorders (HDs) were included in this study. Twenty-five patients who achieved successful outcomes using cryopreserved sperm were also analyzed.

Results

In the men with GCTs and HDs, respectively, differences were observed in age (28 vs 27 years), sperm concentration (32.6 vs 46.1 million/mL, P < 0.05), motility (42.2% vs 41.0%), and the rate of cryopreservation before chemotherapy (90% vs 59%, P < 0.0001). For successful pregnancies and deliveries, age at cryopreservation (30.0 vs 35.3 years, P < 0.05) and disease type (12/16 vs 3/9, P < 0.05) were significant factors.

Conclusions

Compared to patients with GCTs, those with HDs have a lower pregnancy and delivery rate, even though semen quality is higher. Disease type and age at cryopreservation are significant factors for successful outcomes.

Project description:Progress in oncological treatment has led to an improved long-term survival of young male cancer patients over the last decades. However, standard cancer treatments frequently implicate fertility-damaging potential. Cryopreservation of sperm is the current standard option to preserve patient's fertility after treatment, yet long-term data on usage and reproductive experiences is still limited. Natural fertility after treatment and especially in relation to the type of treatment has been poorly analyzed so far. Therefore, we performed a retrospective survey including male patients with an indication for gonadotoxic treatment who cryopreserved reproductive material at our institution between 1994 and 2017. Study questionnaires regarding treatment, material usage, and reproductive outcomes were sent to eligible patients. Additionally, semen analyses of study participants from the time of cryopreservation were evaluated. A total of 99 patients were included in the study. Respondents' median age was 38.0 years. Most frequent diagnoses were testicular cancer (29.3%) and lymphoma (26.3%). A further 8.1% suffered from autoimmune diseases. Testicular cancer patients had a significantly lower pre-treatment median sperm concentration (18.0 million/ml) compared to non-testicular cancer patients (54.2 million/ml). Until November 2020, the determined sperm usage and cumulative live-birth rate per couple were 17.2% and 58.8%, respectively. Most sperm users received treatments with high (40.0%) or intermediate (33.3%) gonadotoxic potential. 20.7% of all patients reported to had fathered at least one naturally conceived child after treatment, this being the case especially if they had been treated with less or potentially gonadotoxic therapies. In conclusion, our findings emphasize the importance of sperm cryopreservation in the context of male fertility preservation. Furthermore, they indicate that the gonadotoxic potential of patients' treatments could represent a predictive factor for sperm usage.

Project description:BackgroundMalignant ovarian sex-cord stromal tumors (MOSCSTs) are rare neoplasms that account for approximately 5-7% of all ovarian malignancies. The majority (70%) of patients had an early stage; thus, surgery is the predominant treatment. Patients were relatively young at the onset of the tumor. Moreover, the prognosis of patients with this tumor is better than that of malignant epithelial ovarian tumors and tends to recur late with an indolent clinical course. Thus, patients may be more inclined to conservative surgical procedures. There is, however, no objective criterion for selecting a suitable surgical procedure. Clinically, surgical extent depended on the preoperative evaluations, age, and willingness of patients, and gynecologists were relatively subjective when choosing surgery. The prognosis of patients with different surgical extents is still controversial. The review aimed to summarize the impacts of different surgical extents on oncological prognosis and fertility outcomes.MethodsThe literature search was performed in PubMed (https://www.ncbi.nlm.nih.gov/pubmed/), and publications between January 2011 and December 2021 in English including clinical cohort studies and case reports were eligible for inclusion.ResultsWe finally identified 12 large-sample retrospective studies and 18 cases of MOSCSTs. The primary surgical procedures include fertility-spring surgery (FSS), total hysterectomy with unilateral or bilateral salpingo-oophorectomy (TAH-USO/BSO), FSS with complete staging procedure, complete staging surgery (CSS), and debulking surgery. FSS includes cystectomy (CYS), unilateral salpingo-oophorectomy (USO) or bilateral salpingo-oophorectomy (BSO) with uterine preservation that allows for potential future assisted reproductive approaches. Complete staging procedure includes peritoneal cytologic examinations, inspections of peritoneal surfaces, random peritoneal biopsies and omentectomy. FSS with complete staging procedure means surgical procedure with uterine preservation and complete staging procedure. And, generally, CSS means TAH-BSO with complete staging procedure.ConclusionIt can be concluded that USO can be done in young, fertility-desired patients with tumors confined to the ovary but avoid CYS. FSS with complete staging procedure is feasible among stage IC-III patients who have fertility desire. Patients can choose to have a complete surgery once their family is complete or without fertility requirements. CSS is recommended for patients with risk factors such as high stage, poor differentiation, and large tumor size and without fertility desire. A close follow-up is essential.
