Fertility and reproductive concerns related to the new generation of cancer drugs and the clinical implication for young individuals undergoing treatments for solid tumors. Eur J Cancer 2024; 202:114010. [PMID: 38520926 DOI: 10.1016/j.ejca.2024.114010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Revised: 03/03/2024] [Accepted: 03/05/2024] [Indexed: 03/25/2024]
Abstract
The treatment landscape of solid tumors has changed markedly in the last years. Molecularly targeted treatments and immunotherapies have been implemented and have, in many cancers, lowered the risk of relapse and prolonged survival. Patients with tumors harboring specific targetable molecular alterations or mutations are often of a younger age, and hence future fertility and family building can be important concerns in this group. However, there are great uncertainties regarding the effect of the new drugs on reproductive functions, including fertility, pregnancy and lactation and how young patients with cancers, both women and men should be advised. The goal with this review is to gather the current knowledge regarding oncofertility and the different novel therapies, including immune checkpoint inhibitors, antibody-drug conjugates, small molecules and monoclonal antibody targeted therapies. The specific circumstances and reproductive concerns in different patient groups where novel treatments have been broadly introduced are also discussed, including those with melanoma, lung, breast, colorectal and gynecological cancers. It is clear, that more awareness is needed regarding potential drug toxicity on reproductive tissues, and it is of essence that individuals are informed based on current expertise and on available fertility preservation methods.

Cancers (Basel) 2023; 15:4170. [PMID: 37627198 PMCID: PMC10453521 DOI: 10.3390/cancers15164170] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 08/16/2023] [Indexed: 08/27/2023] Open
Abstract
PURPOSE To assess the recurrence and birth rates among patients with non-epithelial ovarian cancer. METHODS The study included 146 patients with germ cell (GCT, n = 84) and sex cord-stromal tumors (SCST, n = 62), who underwent fertility-sparing surgery. Adjuvant chemotherapy was administered to 86 (58.9%) patients. Most cases (133 out of 146) were staged FIGO I. RESULTS The 5- and 10-year disease-free survival rates were 91% and 83%, respectively. The recurrence risk was not associated with tumor histology, stage or age. Twenty-four months after the treatment, the rate of recurrence was higher than the rate of childbearing. The childbearing rates kept rising after the treatment and exceeded the rate of recurrence after 2 years. The cumulative incidence rates of birth 36, 60 and 120 months after treatment were 13.24%, 20.75%, and 42.37%, respectively. Chemotherapy was not related to childbearing. The patients' age was related to the chance of childbearing. CONCLUSIONS The prognoses of GCT and SCST are similar. Close follow-ups along with contraception should be offered to women during the first two years after treatment due to the increased risk of recurrence. After this period, relapses are rare and women can safely become pregnant.

Abstract
Female infertility is a significant health issue worldwide with a rising incidence. Anti-cancer therapy is one of the most important reasons for increasing infertility. Although anti-cancer treatment increases the rate of survival, it decreases the quality of life through its side effects. The most substantial side effects are sexual dysfunction and infertility. Breast cancer is the most common cancer. The first-line treatment of breast cancer is chemotherapy by alkylating agents like cyclophosphamide, which leads to infertility. For instance, persistent chemotherapy-induced amenorrhea among breast cancer patients could affect almost half of the patients that undergo such therapy. However, some agents or therapeutic methods can ameliorate these intoxicating effects. Chemotherapy plus gonadotropin-releasing hormone agonist, in breast cancer patients, can not only improve overall survival but also reduce ovarian toxicity. Age plays an essential role in chemotherapy-induced amenorrhea. Chemotherapy at a younger age can reduce the risk of infertility. Gynecological cancers including uterine and ovarian cancer, which have high mortality rates, are the most related cancers to infertility. Surgery is the primary treatment of gynecological cancers. Studies demonstrated that fertility-sparing surgery is a better option than radical surgery. In addition, neoadjuvant chemotherapy is mostly a better option than primary cytoreductive surgery in terms of survival and fertility. Immune checkpoint inhibitors (ICIs) have recently played a major role in treating various cancer types. However, ICIs are associated with hypophysitis, which affects ovaries and can lead to infertility. There are some options for ovarian preservation such as embryo cryopreservation, oocyte cryopreservation, ovarian transposition, ovarian tissue cryopreservation, and ovarian suppression by GnRH agonists. Anti-müllerian hormone level can be utilized to monitor the ovarian reserve. Moreover, to avoid fertility loss, approaches such as using transplantation of human placenta mesenchymal stem cells, administrating anti-inflammatory agents and hormone therapy are under investigation.

Abstract
Background Malignant 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. Methods The 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. Results We 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. Conclusion It 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.

Abstract
Non-epithelial ovarian cancers (NEOC) are a group of uncommon malignancies that mainly includes germ cell tumours (GCT), sex cord-stromal tumours (SCST), and some extremely rare tumours, such as small cell carcinomas and sarcomas. Each of these classifications encompasses multiple histologic subtypes. The aetiology and molecular origins of each sub-group of NEOC require further investigation, and our understanding on the genetic changes should be optimised. In this article, we provide an update on the clinical presentation, pathology, genetics, treatment and survival of the main histological subtypes of the GCT and the SCST, as well as of ovarian small cell carcinomas. We also discuss miRNA expression profiles of NEOC and report the currently active clinical trials that include NEOC.

Abstract
OBJECTIVE To evaluate the outcomes of the first pregnancy after fertility-sparing surgery in patients treated for early-stage ovarian cancer. METHODS We performed a retrospective study of women aged 18-45 years with a history of stage IA or IC ovarian cancer reported to the California Cancer Registry for the years 2000-2012. These data were linked to the 2000-2012 California Office of Statewide Health Planning and Development birth and discharge data sets to ascertain oncologic characteristics and obstetric outcomes. We included in the case group ovarian cancer patients who conceived at least 3 months after fertility-sparing surgery. The primary outcome was preterm birth, and only the first pregnancy after cancer diagnosis was considered. Secondary outcomes included small-for-gestational-age (SGA) neonates, neonatal morbidity (respiratory support within 72 hours after birth, hypoxic-ischemic encephalopathy, seizures, infection, meconium aspiration syndrome, birth trauma, and intracranial or subgaleal hemorrhage), and severe maternal morbidity as defined by the Centers for Disease Control and Prevention. Propensity scores were used to match women in a 1:2 ratio for the case group and the control group. Wald statistics and logistic regressions were used to evaluate outcomes. RESULTS A total of 153 patients who conceived after fertility-sparing surgery were matched to 306 women in a control group. Histologic types included epithelial (55%), germ-cell (37%), and sex-cord stromal (7%). Treatment for ovarian cancer was not associated with preterm birth before 37 weeks of gestation (13.7% vs 11.4%; odds ratio [OR] 1.23, 95% CI 0.69-2.20), SGA neonates (birth weight less than the 10th percentile: 11.8% vs 12.7%; OR 0.91, 95% CI 0.50-1.66), severe maternal morbidity (2.6% vs 1.3%; OR 2.03, 95% CI 0.50-8.25), or neonatal morbidity (both 5.9% OR 1.00, 95% CI 0.44-2.28). CONCLUSION Patients who conceived at least 3 months after surgery for early-stage ovarian cancer did not have an increased risk of adverse obstetric outcomes.

Abstract
Fertility preservation is a novel clinical discipline aiming to protect the fertility potential of young adults and children at risk of infertility. The field is evolving quickly, enriched by advances in assisted reproductive technologies and cryopreservation methods, in addition to surgical developments. The best-characterized target group for fertility preservation is the patient population diagnosed with cancer at a young age since the bulk of the data indicates that the gonadotoxicity inherent to most cancer treatments induces iatrogenic infertility. Since improvements in cancer therapy have resulted in increasing numbers of long-term survivors, survivorship issues and the negative impact of infertility on the quality of life have come to the front line. These facts are reflected in an increasing number of scientific publications referring to clinical medicine and research in the field of fertility preservation. Cryopreservation of gametes, embryos, and gonadal tissue has achieved quality standards for clinical use, with the retrieval of gonadal tissue for cryopreservation being currently the only method feasible in prepubertal children. Additionally, the indications for fertility preservation beyond cancer are also increasing since a number of benign diseases and chronic conditions either require gonadotoxic treatments or are associated with premature follicle depletion. There are many remaining challenges, and current research encompasses clinical health care and caring sciences, ethics, societal, epidemiological, experimental studies, etc.

Abstract
OBJECTIVE To compare reproductive and oncologic outcomes of patients diagnosed with early-stage epithelial ovarian carcinoma, borderline ovarian tumors, or nonepithelial ovarian carcinoma according to receipt of fertility-sparing surgery or conventional surgery. DATA SOURCES PubMed was searched from January 1, 1995, to May 29, 2020. METHODS OF STUDY SELECTION Studies were included if they (1) enrolled women of childbearing age diagnosed with ovarian cancer between the ages of 18 years and 50 years, (2) reported on oncologic and/or reproductive outcomes after fertility-sparing surgery for ovarian cancer, and (3) included at least 20 patients. TABULATION, INTEGRATION, AND RESULTS The initial search identified 995 studies. After duplicates were removed, we abstracted 980 unique citations. Of those screened, 167 publications were identified as potentially relevant, and evaluated for inclusion and exclusion criteria. The final review included 44 studies in epithelial ovarian cancer, 42 in borderline ovarian tumors, and 31 in nonepithelial ovarian carcinoma. The narrative synthesis demonstrated that overall survival does not seem to be compromised in patients undergoing fertility-sparing surgery compared with those undergoing conventional surgery, although long-term data are limited. Areas of controversy include safety of fertility-sparing surgery in the setting of high-risk factors (stage IC, grade 3, and clear cell histology), as well as type of surgery (salpingo-oophorectomy vs cystectomy). It seems that although there may be some fertility compromise after surgery, pregnancy and live-birth rates are encouraging. CONCLUSION Fertility-sparing surgery is safe and feasible in women with early-stage low-risk ovarian cancer. Pregnancy outcomes for these patients also seem to be similar to those of the general population.

Abstract
Although gynecologic cancers usually affect older women, a significant proportion of patients with rare ovarian tumors are of reproductive age. In a young patient who presents with a pelvic mass, a primary consideration should be the probability of a malignancy. If there is any suspicion of a cancer diagnosis, the patient should be referred to a gynecologic oncologist. Key factors in clinical management include assessment of preoperative studies (physical examination, tumor markers, and imaging) to determine the likelihood of a malignancy, appropriate preoperative counseling (including discussion of fertility preservation), choice of surgical approach (minimally invasive vs open), frozen section examination by a gynecologic pathologist, and intraoperative decision making. Fortunately, the clinical features of several rare ovarian tumors are compatible with fertility preservation. These characteristics include a high proportion of stage I disease and unilateral ovarian involvement for most rare histotypes. Once a final diagnosis of a rare ovarian tumor is determined, further clinical management may include the need for further studies, possible referral to a fertility expert, consideration of further surgery (if the initial surgery was incomplete), and recommendations for postoperative therapy. This article reviews the literature on fertility preservation in the context of the treatment of several rare ovarian tumor subtypes, including malignant germ cell tumors, sex cord-stromal tumors, borderline tumors, low grade serous carcinoma, clear cell carcinoma, mucinous carcinoma, and small cell carcinoma of the hypercalcemic type.

Abstract
Approximately 20% of gynecologic malignancies are diagnosed in reproductive-aged women, and standard-of-care surgical treatment often precludes future fertility. In early-stage disease, shared decision making about fertility-sparing medical and surgical approaches may give well-selected patients the opportunity to pursue their family-building goals without compromising long-term survival. Although future fertility is an important consideration for young women with cancer, rates of fertility-sparing procedures remain low. Moreover, because data on pregnancy rates and outcomes after fertility-sparing treatments are limited, it is challenging to counsel patients on realistic expectations. This review examines the critical oncologic outcomes of fertility-sparing approaches in early-stage gynecologic malignancies and highlights pregnancy outcomes in this population.

Abstract
Fertility-sparing management of early-stage gynecologic cancers is becoming more prevalent as increasing evidence demonstrates acceptable oncologic and reproductive outcomes in appropriately selected patients. However, in the absence of randomized controlled trials, most of the commonly used treatment algorithms are based only on observational studies. As women are increasingly postponing childbearing, the need for evidence-based guidance on the optimal selection of appropriate candidates for fertility-sparing therapies is paramount. It is imperative to seriously consider the fertility potential of a given individual prior to making major oncologic treatment decisions that may deviate from the accepted standard of care. It is a disservice to patients to undergo a fertility-sparing procedure in hopes of ultimately achieving a live birth, only to determine later they have poor baseline fertility potential or other substantial barriers to conception including excess financial toxicity. Many women with oncologic diagnoses are of advanced maternal age and their obstetric and neonatal risks must be considered. In the era of advanced assisted reproductive technologies, patients should be provided realistic expectations regarding success rates while understanding the potential oncologic perils. A multidisciplinary approach to the conservative treatment of early-stage gynecologic cancers with early referral to reproductive specialists as well as maternal-fetal medicine specialists is warranted. In this review, we discuss the recommended fertility evaluation for patients with newly diagnosed, early-stage gynecologic cancers who are considering fertility-sparing management.

Abstract
BACKGROUND In Scandinavia, there is a strong tradition for research and quality monitoring based on registry data. In Denmark, Norway and Sweden, 63 clinical registries collect data on disease characteristics, treatment and outcome of various cancer diagnoses and groups based on process-related and outcome-related variables. AIM We describe the cancer-related clinical registries, compare organizational structures and quality indicators and provide examples of how these registries have been used to monitor clinical performance, develop prediction models, assess outcome and provide quality benchmarks. Further, we define unmet needs such as inclusion of patient-reported outcome variables, harmonization of variables and barriers for data sharing. RESULTS AND CONCLUSIONS The clinical registry framework provides an empirical basis for evidence-based development of high-quality and equitable cancer care. The registries can be used to follow implementation of new treatment principles and monitor patterns of care across geographical areas and patient groups. At the same time, the lessons learnt suggest that further developments and coordination are needed to utilize the full potential of the registry initiative in cancer care.

A Swedish Nationwide prospective study of oncological and reproductive outcome following fertility-sparing surgery for treatment of early stage epithelial ovarian cancer in young women. BMC Cancer 2020; 20:1009. [PMID: 33076846 PMCID: PMC7574478 DOI: 10.1186/s12885-020-07511-y] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2020] [Accepted: 10/07/2020] [Indexed: 12/21/2022] Open
Abstract
Background Epithelial ovarian cancer (EOC) is rare in women of reproductive age and fertility-sparing surgery (FSS) may be applied in early stages. The purpose of this study was to investigate the safety and efficacy of FSS for treatment of EOC. Methods The Swedish nationwide population-based Quality Register for Gynecological Cancer was used to identify all women 18–40 years of age diagnosed with stage I EOC between 2008 and 2015. Detailed data on surgery, staging, histopathology, and follow-up were extracted and reviewed. Cross-linking of individuals to population-based registries allowed retrieval of data on obstetrical and reproductive outcomes after FSS. Disease-free survival (DFS) and overall survival (OS) rates were compared (Kaplan-Meier method) between women who underwent FSS vs. radical surgery (RS). Results In total 83 women were identified; 36 who had FSS performed and 47 RS. The 5-year OS rate was 92% and no statistical differences between DFS or OS were found between women treated by FSS or RS. The recurrence rate after RS was 13% compared to 6% after FSS. Recurrences were more frequently found in women with stage IC tumor or with histologic subtypes with more aggressive behavior. In the FSS cohort, nine women gave birth to 12 healthy children, all delivered at fullterm. Only one women had received assisted reproductive technology treatment. Conclusion In this nationwide population-based cohort study natural fertility was maintained after FSS. Specific histologic subtypes showed greater prognostic impact on the oncological outcome than the use of FSS. Recurrences occurred after FSS, but none in the uterus, which questions the need of hysterectomy in young women with EOC. Trial registration This article reports the results of a healthcare intervention using the data prospectively registered in the Swedish population-based registries including the Quality Register for Gynecological Cancer, the National Death Register, the Swedish Medical Birth Register, and the National Quality Register for Assisted Reproduction.

Abstract
MOGCTs (malignant ovarian germ cell tumors) are rare tumors that mainly affect patients of reproductive age. The aim of this study was to evaluate the fertility and survival outcomes in young women with MOCGTs treated with fertility-sparing surgery (FSS).From 2000 to 2018, data from 28 patients of reproductive age with a diagnosis of MOGCT at the University of Bari were collected. Most received FSS, and in patients treated conservatively, the reproductive outcome and survival were investigated. Data of patient demographics, clinical presentation, oncology marker dosage, staging, type of surgery, histological examination, survival, and reproductive outcome were collected from hospital and office charts. All informed consent was obtained from all patients. The median age was 24 (range: 9-45 years). The majority of the patients had stage IIIC. Twenty-four woman received FSS consisting of unilateral ovariectomy and omentectomy, whereas only 4 women, based on their stage (IIIC), received a radical surgery (hysterectomy with bilateral adnexectomy, lymphadenectomy, and omentectomy). Our study shows that FSS in MOGCTs can produce good results both on reproductive outcomes and on survival. Indeed, in our group, there was only 1 case of exitus as result of recurrence. Furthermore, patients after FSS maintained normal ovarian function and 5 of 5 women who tried to get pregnant succeeded spontaneously. The median follow-up was 90 months (range 3-159).Conservative surgery for MOGCTs should be considered for women of reproductive age who wish to preserve fertility.

Abstract
OBJECTIVE To assess the efficacy of fertility-sparing surgery (FSS) in terms of reproductive outcomes by following FSS for borderline ovarian tumors (BOTs) and comparing the safety of FSS versus radical surgery (RS). DESIGN Nationwide cohort study based on prospectively recorded data. SETTING Sweden. PATIENT (S) All women of reproductive age (18-40 years) treated in Sweden for stage I BOT with the use of FSS or RS from 2008 to 2015, identified in the Swedish Quality Registry for Gynecologic Cancer (SQRGC). INTERVENTIONS (S) FSS or RS. MAIN OUTCOME MEASURE (S) Reproductive outcomes: natural conception, use of assisted reproductive technology (ART), live birth and obstetrical outcomes. Safety outcome: overall survival (OS) rates, comparing women undergoing FSS versus RS. The FSS cohort was linked to the Swedish Medical Birth Register to identify all women who had given birth after FSS and to obtain detailed obstetrical data. For information on ART treatment, the National Quality Registry for Assisted Reproduction was consulted. OS rate comparisons were conducted by means of Kaplan-Meier estimates. RESULT (S) Of the 277 women with BOTs, 213 (77%) underwent FSS, 183 (86%) unilateral salpingo-oophorectomy, and 30 (14%) cystectomy. Following FSS, 50 women gave birth to 62 healthy children, 8% of which were preterm. Only 20 (9%) of the women underwent ART treatment. OS was similar in women treated with FSS and RS. CONCLUSION (S) Natural fertility was maintained after FSS; only 9% required ART treatment. FSS was also deemed to be equivalent to RS regarding survival outcome.

Abstract
Ovarian diffuse large B-cell lymphoma (DLBCL) is rare. DLBCL is a complex type of lymphoma. The ovarian DLBCL usually harbor a favorable prognosis. We report a case of ovarian DLBCL that presented as an ovarian mass with lower abdominal pain and was managed using laparoscopic staging surgery. A 29-year-old female (gravida 2, para 0, abortion 2) with a history of polycystic ovarian syndrome with irregular medication control visited our clinic due to lower abdominal pain. Transvaginal ultrasound revealed a heterogeneous, septated mass over the left adnexa with a diameter of approximately 6 cm × 8 cm. The tumor marker CA 19-9 was elevated (65.77 IU/mL); CA125 and carcinoembryonic antigen were not elevated. Laparoscopic surgery with left salpingo-oophorectomy was first performed. Frozen section indicated dysgerminoma. Then, we continued staging surgery through bilateral pelvic lymph node dissection, para-aortic lymph node dissection, omentectomy, right ovary and peritoneum biopsy, and washing cytology. Ovarian tumor and para-aortic lymph nodes were positive for lymphoma. The tumor cells were positive staining for CD20, CD5, ki67, BCL-6, and MUM-1, which was associated with DLBCL. The patient was then consulted for oocyte preservation and referred to hematology for further chemotherapy. In conclusion, an ovarian lymphoma is a rare event. The presence of an enlarged ovarian tumor should raise the suspicion of ovarian lymphoma. To differentiate ovarian lymphoma from dysgerminoma, immunohistochemistry is useful. Fertility preservation should be considered before chemotherapy. Ovarian tissue or oocyte preservation or gonadotropin-releasing hormone agonist injection before chemotherapy can be performed for fertility preservation.

Abstract
Adolescents and young adults (AYA) patients with cancer show specific biological, sociodemographic and behavioral features, with lower survival rates than younger group. Gynecologic malignancies that occur among AYA requires a multidisciplinary management and a tailored model of care, in order to enhance the early diagnosis, the adherence to the treatment, the enrollment in clinical trials, the rate of survival and the quality of life (QoL). In this article, we review the main gynecological tumors that may occur in AYA, with a focus on the clinical signs at the diagnosis and the modality of treatment. In addition, we proposed a model of multidisciplinary and personalized care for AYA with gynecological tumors, which can help the clinicians to manage the specific gynecologic concerns, such as ovarian failure, contraception, fertility, late psychosocial effects.
