Reproduction beyond cancer: A message of hope for young women

Quantification of follicles in human ovarian tissue using image processing software and trained artificial intelligence†

Cancer survival rates in prepubertal girls and young women have risen in recent decades due to increasingly efficient treatments. However, many such treatments are gonadotoxic, causing premature ovarian insufficiency, loss of fertility, and ovarian endocrine function. Implantation of donor ovarian tissue encapsulated in immune-isolating capsules is a promising method to restore physiological endocrine function without immunosuppression or risk of reintroducing cancer cells harbored by the tissue. The success of this approach is largely determined by follicle density in the implanted ovarian tissue, which is analyzed manually from histologic sections and necessitates specialized, time-consuming labor. To address this limitation, we developed a fully automated method to quantify follicle density that does not require additional coding. We first analyzed ovarian tissue from 12 human donors between 16 and 37 years old using semi-automated image processing with manual follicle annotation and then trained artificial intelligence program based on follicle identification and object classification. One operator manually analyzed 102 whole slide images from serial histologic sections. Of those, 77 images were assessed by a second manual operator, followed with an automated method utilizing artificial intelligence. Of the 1181 follicles the control operator counted, the comparison operator counted 1178, and the artificial intelligence counted 927 follicles with 80% of those being correctly identified as follicles. The three-stage artificial intelligence pipeline finished 33% faster than manual annotation. Collectively, this report supports the use of artificial intelligence and automation to select tissue donors and grafts with the greatest follicle density to ensure graft longevity for premature ovarian insufficiency treatment.

Current limits of conservative treatment in ovarian cancer

PURPOSE OF REVIEW

Fertility-sparing surgery in ovarian cancer is an increasing need in gynecology-oncology clinical practice because of the frequent childbearing delay in developed countries. As the evidence in literature is based on observational studies, this review focuses on summarizing the most recent and relevant evidence for the conservative management of young patients with ovarian cancer.

RECENT FINDINGS

Staging surgery is mandatory in epithelial ovarian tumors. In sex cord-stromal tumors, fertility-sparing surgery is only recommended in FIGO stage IA. Due to its good prognosis, conservative treatment is possible in some cases of advanced disease of germ cell tumors and borderline tumors. Cystectomy is a reasonable option in serous borderline tumors but is not recommended in other tumor subtypes. Successful conception rates after fertility-sparing surgery ranges from 30 to 60%.

SUMMARY

Fertility-sparing surgery is a well tolerated option in young women with early-stage ovarian cancer with acceptable reproductive outcomes.

Incidence and Survival Rates for Female Malignant Germ Cell Tumors: An Institutional Review

Background

Germ cell tumor survival rates have improved over the past few decades. However, there is a lack of data on survival rates and the incidence of female germ cell tumors. This study aims to determine the incidence and survival rates of female germ cell tumors in our institution.

Methodology

This retrospective cross-sectional study was carried out at Shaukat Khanum Memorial Hospital and Research Centre, and the records over 10 years, from January 2010 to December 2020 were examined. The data of 290 females with malignant germ cell tumors were selected from 1387 females with ovarian masses, and their survival records were examined. For statistical analysis, SPSS software (version 24.0; IBM Corp. Armonk, NY) was utilized. The survival analysis was determined using the Kaplan-Meier method.

Results

The mean age of patients was 21.45 ± 9.28 years. The mean duration of diagnosis was 4.53 ± 2.59 years. In 245 (84.5%) patients, ovarian malignancy was involved while uterine malignancy was observed in 44 (15.2%) cases and there was one (0.3%) case of cervical carcinoma. The most common stage at diagnosis of malignancy was IA (96 (33.1%)), followed by IIIC (58 (20.0%)), IV (56 (19.3%)) and IC (26 (9.0%)). Chemotherapy was given in 244 (84.1%) cases. Out of 290 cases, 26 (9.0%) had a recurrence of the tumor while 264 (91.0%) did not have a recurrence of the tumor. Out of 290 cases, 46 (15.9%) died during follow-up, 129 (44.4%) had disease-free survival while 115 (39.7%) were healthy till the end of the study. The mean duration of survival was 3.56 ± 2.33 years. When patients' survival was compared between treatment groups, patients who did not receive chemotherapy fared better than those who did.

Conclusion

Female germ cell tumor patients have a good overall survival rate of more than 20% after 10 years of follow-up with effective adjuvant therapy and conservative surgery. However, more research is needed to determine the long-term effects of chemotherapy on ovarian function.

A review on the relationship between anti-mullerian hormone and fertility in treating young breast cancer patients

Despite the fact that the long-term survival rate of breast cancer patients had been significantly improved owing to the systemic breast cancer therapies, there are still some side effects such as amenorrhea and fertility retention to be resolved, leaving it an important thing to understand the possible side effects on fertility and fertility preservation strategies while undergoing breast cancer treatment, due to the fact that most young patients hope to become pregnant and have children after breast cancer treatment. With anti-müllerian hormone (AMH) being the most sensitive marker for predicting ovarian function in young premenopausal women with breast cancer, this review is aimed to provide the additional guidance for clinical application of AMH by exploring the impacts of AMH on the fertility of young breast cancer patients, the relationship between AMH and metabolism, and the relationship between BRAC gene mutation and fertility protection strategies.

Fertility sparing surgery in malignant ovarian Germ cell tumor (MOGCT): 15 years experiences

Aim

We aim to evaluate the reproductive outcome of fertility-sparing surgery and chemotherapy among young women diagnosed with MOGCT of any stage.

Methods

In the current retrospective study we evaluated 79 patients with malignant ovarian germ cell tumors (MOGCT) who visited at Imam Center, Vali-e-asr Hospital, Gynecologic Oncology department during 2001–2016. Reproductive outcomes (menstruation status and childbearing) followed fertility-preserving surgery and adjuvant chemotherapy by filling questionnaires. Statistical analysis was done with SPSS software, Chi-Square Tests were done, and significance was determined at P ≤ 0.05. Results among 79 young women who underwent fertility-sparing treatment, 72 patients followed up for reproductive outcome, and 7 patients excluded because of death (3 cases), XY genotyping (3 cases), and bilateral ovarian involvement (1 case). The mean age at presentation was 23 years. (Range: 19–33 years). The 5 and 10-year disease-free survival rate was 87% and 94.4%, respectively. The overall survival rate (OSR) was 94.4% at 5 and 10 years. Regular menstruation recovered in 60 of 72 patients after treatment (83%). All patients without adjuvant chemotherapy experienced regular menstruation, while normal menstruation was retrieved in 78% in the adjuvant chemotherapy group at the end of treatment. This retrieval of regular menstruation was not dependent on the age or number of chemotherapy cycles. 19 of 26 patients who attempted pregnancy were led to delivery (73%). No one required infertility treatments. The mean of chemotherapy cycles is related to a successful pregnancy.

Conclusion

We showed patients with MOGCT could become pregnant and give birth if they desire. The advanced tumor stage wasn't the convincing factor for avoiding fertility preservation. Fertility sparing surgery with adjuvant chemotherapy is a safe treatment and results in a high fertility rate.

Fresh and cryopreserved ovarian tissue from deceased young donors yields viable follicles

OBJECTIVE

Ovarian tissue cryopreservation is one of the crucial options for fertility preservation. Transplantation of cryopreserved ovarian tissue was proven to restore ovarian endocrine function in patients with premature ovarian insufficiency. Ovaries from deceased donors potentially serve as an excellent and readily available tissue for the translational and basic research. In this study, we used ovaries obtained from 5 deceased donors aged 18-26 years, to evaluate the number and quality of ovarian follicles isolated before and after cryopreservation.

DESIGN

Preclinical.

SETTING

Academic biomedical research laboratory.

PATIENTS

De-identified deceased human donors.

INTERVENTIONS

Slow-freeze cryopreservation and thawing.

MAIN OUTCOME MEASURES

Follicle count, follicle density, follicle viability using immunohistochemical staining (TUNEL).

RESULTS

The follicle density negatively correlated with age in both cryopreserved/thawed and fresh group. A total of 2803 follicles from fresh and 1608 follicles from cryopreserved tissues were classified and analyzed using Hematoxylin and eosin staining. There was no significant difference in the percent of morphologically normal follicles between two groups. TUNEL assay indicated no higher DNA damage in the follicles and the stroma cells after cryopreservation. Morphologically normal preantral follicles were enzymatically isolated from both fresh and cryopreserved tissue with 88.51 ± 5.93% (mean ± SD) of the isolated follicles confirmed viable using LIVE/DEAD evaluation.

CONCLUSIONS

Our results indicate the ovarian tissue from deceased donors maintain high quality after long time extracorporeal circulation and transportation from the hospital to the laboratory. High survival rate of follicles at different developmental stages suggested tolerance to the cryopreservation process. Human ovarian tissues obtained from deceased donors is an ample source tissue and can be applied to promoting research and future clinical applications.

Quality of life and fertility preservation counseling for women with gynecological cancer: an integrated psychological and clinical perspective

Purpose: Relational and sexual problems are frequent in patients with a diagnosis of gynecological cancer, because this disease has a strong negative impact on female identity and sexuality. Psychological and sexual functioning is affected by inauspicious diagnosis. Furthermore, therapies may compromise reproductive function. The aim of this study is to propose a general overview on the impact of gynecological cancer on quality of life and psychological and sexual functioning, as well as on the importance of adequate counseling related to fertility preservation techniques.Materials and methods: We provide a narrative overview of the recent literature about quality of life and fertility preservation counselling in women with gynecological cancer.Results and conclusions: According to recent studies, 75% of women between 18 and 45 years with a diagnosis of cancer wish to have children. When cancer affects the reproductive system, the psychological distress is even stronger because there is a loss of menstrual function and fertility. Currently, fertility preservation techniques in women with gynecological cancer are beneficial and lead to an improvement in the quality of life.

Fertility preservation in women affected by gynaecological cancer: the importance of an integrated gynaecological and psychological approach

Gynaecological cancer treatment significantly affects the fertility of women in reproductive age. Surgery, chemotherapy and radiotherapy are the mainstays of ovarian, cervical and endometrial cancers and anatomically or functionally impact the uterus and ovaries. Moreover, the sexual function and psychological wellbeing of patients are highly weakened after a cancer diagnosis: depression, anxiety and impairment of quality of life represent a relevant concern for patient care. The potential loss of fertility could be more distressing than cancer itself. For this reason, it is of paramount importance to try to preserve fertility in women affected by gynaecological cancers. Recently, tailored fertility preservation therapies have been developed to meet the childbearing demand from more than half of women between 18 and 40 years with a diagnosis of cancer. Currently, fertility preservation techniques play a significant role in improving the quality of life of women with gynaecological cancer. In this scenario, we propose a narrative overview of the recent literature about the importance of a multidisciplinary approach in the management of fertility preservation in the case of gynaecological cancers.

Survival of isolated human preantral follicles after vitrification: Analyses of morphology and Fas ligand and caspase-3 mRNA expression

Objective

This study aimed to examine the effect of vitrification on apoptosis and survival in human preantral follicles after thawing.

Methods

This experimental study was conducted at an acute tertiary care hospital from March 2012 to April 2013. Ovaries were sliced into 5×5×1-mm pieces and divided into the following three groups: preantral follicle isolation, ovarian tissue vitrification-warming followed by follicle isolation, and immunohistochemistry of fresh ovarian tissue. For statistical analyses, the Student t-test, chi-square test, Kruskal-Wallis test, and Kaplan-Meier survival analysis were used.

Results

A total of 161 preantral follicles (70% secondary) were collected from ovarian cortex tissue of six women between 30 and 37 years of age who underwent oophorectomy due to cervical cancer or breast cancer. There were no significant differences in the follicular morphology of fresh preantral follicles and vitrified follicles after thawing. The mean Fas ligand (FasL) mRNA expression level was 0.43±0.20 (relative to β-actin) in fresh preantral follicles versus 0.51±0.20 in vitrified follicles (p=0.22). The mean caspase-3 mRNA expression level in fresh preantral follicles was 0.56±0.49 vs. 0.27±0.21 in vitrified follicles (p=0.233). One vitrified-thawed secondary follicle grew and developed to an antral follicle within 6 days of culture.

Conclusion

Vitrification did not affect preantral follicle morphology or mRNA expression of the apoptosis markers FasL and caspase-3. Further studies are required to establish whether vitrification affects the outcomes of in vitro culture and the maturation of preantral follicles.

Methods of Treatment and Outcome for Ovarian Germ Cell Tumors

Ovarian germ cell tumors account for about 15-20% of all ovarian tumors. They occur mainly in girls, adolescents, and young adults. This study aims to assess the different clinico-pathological factors of ovarian germ cell tumors, treatment methods, and outcome. This is a retrospective observational cohort study including 54 cases with OGCTs which were studied from the period between January 2013 and December 2016. The study was performed at National Cancer Institute (NCI)-Cairo University, Egypt. All cases had cytoreductive surgery in the form of unilateral salpingo-oophorectomy in 42 cases and total abdominal hysterectomy in 12 cases. Complete cytoreduction was achieved in 46 cases while 8 cases had residual disease after surgery. Adjuvant chemotherapy was given in 26 cases (stage II, III, and IV malignant OGCTs). The main treatment of ovarian germ cell tumors is complete cytoreductive surgery which can be achieved in many cases with unilateral salpingo-oophorectomy. Adjuvant chemotherapy is highly recommended in case of malignant ovarian germ cell tumors.

Issues with Fertility in Young Women with Breast Cancer

PURPOSE OF REVIEW

There are competing risks and benefits of cancer therapies and fertility preservation in young women with breast cancer. Here we discuss the impact of therapy on fertility, fertility preservation options, and emerging information in fertility issues for the breast cancer patient.

RECENT FINDINGS

All systemic forms of breast cancer treatment can impact future fertility. Pre-therapy fertility preservation may offer the best opportunity for future fertility. Shared decision making with the individual patient and clinical scenario is important. Early referral to a fertility specialist should be offered to young patients. We find that fertility preservation options for young women diagnosed with breast cancer are currently available, but potentially under-utilized. We conclude that a multidisciplinary approach is necessary, with discussion of potential risks and benefits of fertility preservation options in the context of the patient's clinical disease.

Survivorship needs of adolescent and young adult cancer survivors: a concept mapping analysis

PURPOSE

Adolescents and young adults (AYAs) with cancer are known to have complex medical and psychosocial needs throughout treatment; however, information is lacking about the challenges AYA survivors face after treatment has ended. Focus groups were conducted using a concept mapping framework to better understand the most important issues these patients face in transitioning to survivorship and how prepared they felt to face them.

METHODS

AYAs diagnosed between 18 and 39 years old and at least 2 years post-treatment participated in one of six focus groups based on age group and follow-up status. Using a concept mapping design, participants provided important issues during the transition to survivorship and appraised them on three core areas of interest.

RESULTS

Analyses revealed salient themes shared across age and follow-up group status, particularly related to the psychosocial, emotional, and cognitive effects of treatment. Differential concerns included those related to patients' developmental concerns-namely, finding a new identity, financial burden of treatment, and fertility concerns after treatment.

CONCLUSIONS

AYA cancer survivors continue to have a myriad of issues beyond the immediate treatment phase. Despite a complex list of challenges, these issues largely remained unaddressed by their oncology provider and left patients feeling overwhelmingly ill-prepared to manage their transition to survivorship.

IMPLICATIONS FOR CANCER SURVIVORS

AYA cancer survivors have many unaddressed concerns as they transition out of active cancer treatment, largely related to developmental issues they are facing. Survivorship care for these patients would benefit from care planning that takes these unique concerns into account.

Sarcopenia in Ovarian Cancer Patients, Oncologic Outcomes Revealing the Importance of Clinical Nutrition: Review of Literature

INTRODUCTION

Ovarian cancer is the leading cause of death among gynecological malignancies. Its usual clinical manifestation is at advanced stages, with nutritional impairment, weight loss, and a consequent decline in skeletal muscle mass and strength (defined as sarcopenia). The relationship between sarcopenia and decreased survival was demonstrated not only in ovarian cancer but also in other cancer types, such as hepatocellular, pancreatic, lung, colon, cervical, metastatic breast, and renal cancer. The aim of this study is to review the current evidence regarding the relationship between sarcopenia and the surgical and oncological outcomes in ovarian cancer patients.

METHODS

The systematic search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRSIMA) statement. The terms "SARCOPENIA" AND "OVARIAN CANCER" were systematically used to search PubMed and Scopus databases. Original reports in English language were identified, with the purpose to include all relevant papers regarding the role of sarcopenia and indicators of skeletal muscle quality assessment in gynecological ovarian cancer.

RESULTS

A total of 9 studies were considered eligible for the present review. The strength of recommendation was moderate and the level of evidence was low in all selected articles. No prospective studies were conducted and most of the papers were case-control series comparing ovarian cancer sarcopenic population vs. non sarcopenic population.

CONCLUSIONS

Sarcopenia appears to have an important role in oncological outcomes of ovarian cancer patients. However, sarcopenia occurrence during disease history and mechanisms underlying the possible impairment in prognosis should be better investigated. Prospective trials are awaited in order to obtain a better insight in this topic.

Early-Onset Breast Cancer: Effect of Diagnosis and Therapy on Fertility Concerns, Endocrine System, and Sexuality of Young Mothers in Germany

Background

The purpose of this study was to analyze the effect of breast cancer therapy on fertility concerns and sexuality of young mothers with breast cancer in Germany.

Methods

During a mother-child rehabilitation program, 1,191 young mothers with locoregional primary breast cancer, treated between 2006 and 2014, were recruited. Data included sociodemographic data, TNM stage, tumor biology, therapies, and patient-reported outcomes such as sexuality and fertility concerns.

Results

The mean age at diagnosis was 40 years. Approximately a quarter of the patients stated that family planning had not been completed at the time of diagnosis. Nearly half of all patients had been informed as to how treatment could affect fertility, but counseling at a specialized fertility center was offered to only 13%. Of all patients, 4% took a consultation and 2% underwent fertility preservation procedures.

Conclusion

Our study indicates that only a minority of patients is referred to fertility centers although family planning is incomplete at the time of diagnosis in about 25% of young women with breast cancer. Thus, these patients should not only be informed about the effects of treatment on fertility and sexuality, but should be referred to a fertility center.

Successful controlled ovarian stimulation and vitrification of oocytes in an adolescent diagnosed with myelodysplastic/pre-malignant clone with monosomy 7

An improvement in long-term outcomes for malignancies and non-malignant conditions, together with a review of the NICE Guideline, has led to a need to provide clinical services to deal with the sequelae of disease, its treatment, and subsequent survival of young people diagnosed with cancer. In this article, we describe fertility preservation in an adolescent female diagnosed with Myelodysplastic/pre-malignant Clone with Monosomy 7 with pathophysiology like that of chronic myeloid leukaemia (CML) with known genetic markers in the tumour cells. We used random start controlled ovarian stimulation (COS) leading to oocyte collection and vitrification of metaphase II oocytes. Despite successful COS and vitrification, there remain numerous ethical considerations that merit more focussed discussion. Not least, in determining best practice for informed consent, but consideration of individualised protocols for ovarian stimulation, monitoring follicular development, together with prevention of ovarian hyperstimulation syndrome (OHSS) when considering most appropriate trigger for oocyte maturation. Random-start controlled ovarian stimulation and oocyte vitrification for adolescent girls diagnosed with cancer can be safely achieved through a collaborative, multidisciplinary and expert team approach. This case study offers a promising approach to fertility preservation, and would minimise the risk of introducing malignant cells after recovery.

Psychological impact of fertility preservation techniques in women with gynaecological cancer

Gynaecological cancer is a very stressful experience for women and treatments can compromise fertility and reproductive capacity. Fertility preservation techniques in women with gynaecological cancer can play an important role in improving the quality of life of these patients but, in many cases, the information about this type of treatment is not adequate. It is important to further investigate this topic in order to reduce the impact of gynaecological cancer on the quality of life of survivors as much as possible.

Pediatric Oncology Nurses' Attitudes Related to Discussing Fertility Preservation With Pediatric Cancer Patients and Their Families

This study explores nurses' attitudes toward the discussion of fertility preservation (FP) with pediatric cancer patients and their families. A cross-sectional survey was administered to attendees of a pediatric oncology conference. Of the 115 nurses who responded and comprised the study sample, most reported discussing risks of infertility or FP ≤ 50% of the time. The 3 attitudinal factors most commonly rated by nurses to influence discussion of FP are the potential of upsetting patients' families, that boys younger than 18 years should not be given erotic materials during semen collection, and difficulty locating FP facilities. The 3 patient factors most likely to encourage the discussion of FP are the patient being recently married or engaged, the patient asking about FP, and availability of patient education materials. While the results indicate that nurses do not regularly discuss FP with their patients, nurses perceive such discussion as being within their scope of practice. Therefore, with appropriate intervention, nurses may play a key role in facilitating discussions regarding FP with patients and families.

Regret around fertility choices is decreased with pre-treatment counseling in gynecologic cancer patients

PURPOSE

Data have demonstrated an association between regret and lack of fertility counseling among patients undergoing treatment for non-gynecologic cancers. We sought to determine if fertility-related regret is reduced with pre-treatment counseling or fertility-sparing surgery (FSS) in patients with gynecologic cancers.

METHODS

A cross-sectional survey was administered to 593 reproductive-age survivors (18-40 years old at diagnosis) of localized cervix, ovarian, or endometrial cancers that were eligible for FSS. A validated decision regret score was used to evaluate regret in patients.

RESULTS

Four hundred seventy women completed the survey. Forty-six percent received pre-treatment counseling about treatment's effects on fertility. Having received counseling (adjusted ß-coefficient of -1.24, 95 % CI = -2.29 to -0.18, p = 0.02), satisfactory counseling (adjusted ß-coefficient of -2.71, 95 % CI = -3.86 to -1.57, p < 0.001), and FSS (adjusted ß-coefficient of -1.26, 95 % CI = -2.39 to -0.14, p = 0.03) were associated with lower regret post-treatment, after adjusting for age. Time since diagnosis, prior parity, socioeconomic status and cancer type were not associated with regret (p > 0.05). While 50 % of women reported desiring more children after diagnosis, desire for children after treatment was associated with increased regret (adjusted ß-coefficient of 3.97, 95 % CI = 2.92-5.02, p < 0.001).

CONCLUSIONS

Though less than half of study participants received counseling about the effect of cancer treatment on future fertility, both fertility counseling and FSS were associated with decreased regret in reproductive-aged women with gynecologic cancers. The desire for more children after treatment was associated with increased regret.

IMPLICATIONS FOR CANCER SURVIVORS

Inquiring about fertility desires and providing counseling regarding reproductive outcomes following cancer treatment should be implemented as part of the treatment process.

Ectopic pregnancy secondary to in vitro fertilisation-embryo transfer: pathogenic mechanisms and management strategies

BACKGROUND

Ectopic pregnancy (EP) is the leading cause of maternal morbidity and mortality during the first trimester and the incidence increases dramatically with in vitro fertilisation and embryo transfer (IVF-ET). The co-existence of an EP with a viable intrauterine pregnancy (IUP) is known as heterotopic pregnancy (HP) affecting about 1% of patients during assisted conception. EP/HP can cause significant morbidity and occasional mortality and represent diagnostic and therapeutic challenges, particularly during fertility treatment. Many risk factors related to IVF-ET techniques and the cause of infertility have been documented. The combination of transvaginal ultrasound (TVS) and serum human chorionic gonadotrophin (hCG) is the most reliable diagnostic tool, with early diagnosis of EP/HP permitting conservative management. This review describes the risk factors, diagnostic modalities and treatment approaches of EP/HP during IVF-ET and also their impact on subsequent fertility treatment.

METHODS

The scientific literature was searched for studies investigating EP/HP during IVF-ET. Publications in English and within the past 6 years were mostly selected.

RESULTS

A history of tubal infertility, pelvic inflammatory disease and specific aspects of embryo transfer technique are the most significant risk factors for later EP. Early measurement of serum hCG and performance of TVS by an expert operator as early as gestational week 5 can identify cases of possible EP. These women should be closely monitored with repeated ultrasound and hCG measurement until a diagnosis is reached. Treatment must be customised to the clinical condition and future fertility requirements of the patient. In cases of HP, the viable IUP can be preserved in the majority of cases but requires early detection of HP. No apparent negative impact of the different treatment approaches for EP/HP on subsequent IVF-ET, except for risk of recurrence.

CONCLUSIONS

EP/HP are tragic events in a couple's reproductive life, and the earlier the diagnosis the better the prognosis. Due to the increase incidence following IVF-ET, there is a compelling need to develop a diagnostic biomarker/algorithm that can predict pregnancy outcome with high sensitivity and specificity before IVF-ET to prevent and/or properly manage those who are at higher risk of EP/HP.

Incidence of chemotherapy- and chemoradiotherapy-induced amenorrhea in premenopausal women with stage II/III colorectal cancer

BACKGROUND

The incidence rates of colorectal cancer (CRC) in young individuals are increasing. There has been a significant improvement in overall survival in CRC because of advances in adjuvant chemotherapy and chemoradiotherapy over the past decades. However, these procedures may compromise the function of the reproductive system, and ovarian failure and premature menopause may occur. The objective of this analysis was to determine the incidence of long-term amenorrhea (≥ 12 months) in women with CRC aged 40 years and younger after adjuvant treatment.

PATIENTS AND METHODS

The authors identified 162 premenopausal women with CRC aged 40 years or younger who were treated with adjuvant chemotherapy and chemoradiotherapy at Fudan University Shanghai Cancer Center from January 2008 to December 2012. One hundred twenty-three patients met all eligibility criteria and had sufficient follow-up for evaluation. The median age at diagnosis in patients with colon and rectal cancers was, respectively, 36 and 35 years (range, 17-40 and 24-40 years).

RESULTS

All patients had regular menses before treatment; 3 patients with colon cancer (4.2%) experienced long-term amenorrhea, and 48 patients with rectal cancer (94.1%) experienced long-term amenorrhea. The incidence of amenorrhea was significantly lower in patients with colon cancer (4.2%; 3 of 72) than in patients with rectal cancer (94.1%; 48 of 51) (P < .01).

CONCLUSION

In this retrospective series, the incidence of amenorrhea in patients with colon and rectal cancers was 4.2% and 94.1%, respectively. We believe our data support the fact that young female patients with CRC, especially those with rectal cancer who are scheduled to undergo pelvic irradiation, should be counseled regarding fertility preservation options, including ovarian transposition and cryopreservation of ovarian tissue, embryo, or oocyte.

Childbearing attitudes and decisions of young breast cancer survivors: a systematic review

BACKGROUND

Young breast cancer survivors often need to deal with adverse effects of treatments on fertility and complex reproductive decisions. In this systematic review, we highlight what is known about childbearing and parenthood attitudes and decisions of young breast cancer survivors from their own perspective.

METHODS

We conducted manual and electronic searches on Pubmed, PsychInf and CINAHL databases for articles, published in English between 1 January 1990 and 31 October 2012, that assessed childbearing, pregnancy and parenthood attitudes/decisions of female breast cancer survivors (premenopausal and/or <50 years old). Eligible articles were classified into quantitative studies, qualitative studies and mixed methods studies. Data from each study were individually extracted by all the authors, and standardized tables were created and discussed to ensure congruence of the information extracted.

RESULTS

Of the 493 publications identified in PubMed (results are presented for PubMed searches as the other databases did not yield any new relevant papers), 8 met the inclusion criteria, in addition to 2 publications retrieved manually. A total of 10 studies provided information on pregnancy and parenthood attitudes and decisions, in addition to risks and benefits of childbearing after breast cancer. Survivors had mixed attitudes towards the issue. Fear associated with future pregnancy was reported, namely the risk of cancer recurrence. However, for many survivors, pregnancy and parenthood can represent normalcy, happiness and life fulfilment.

CONCLUSIONS

Childbearing after breast cancer is an important issue for survivors. Future larger and prospective studies should be implemented to increase certainty of conclusions of current research. Clinicians may benefit from a deeper understanding of the importance of pregnancy and parenthood to survivors in order to provide the needed educational and psychosocial support services, overcome misinformation and better assist women with their fertility-related decisions.

Association Between Reproductive Cancer and Fetal Outcomes: A Systematic Review

Objective

This study aimed to review studies that addressed the impact of previous reproductive cancer diagnosis on selected fetal birth outcomes.

Materials and Methods

We searched PubMed and Web of Knowledge to identify peer-reviewed articles published from January 1992 to December 2012, investigating the association between reproductive cancer and birth outcomes. After applying exclusion criteria, 49 articles were identified for full review, and 36 articles were finally selected for this systematic review. The quality of the studies was assessed by independent reviewers.

Results

We found 13 cervical cancer studies, 16 ovarian cancer studies, and 7 corpus uteri cancers that reported subsequent pregnancies (n = 688 pregnancies in 477 women). Of these, 489 pregnancies reached third trimester. Among viable pregnancies, only 416 pregnancies had information on maturity status based on gestational age and/or birth weight. For those with cervical cancer, the preterm birth (PTB) rate was 48.5%. For those with ovarian cancer, there were no cases of PTB. For those with corpus uteri cancers, the PTB was 7.7%. All studies had small sample sizes, and there was considerable heterogeneity of results. Abortions, ectopic pregnancies, and terminations were also reported.

Conclusions

Reproductive cancers may be associated to subsequent adverse fetal birth outcomes; however, the quality of evidence is still insufficient to infer a relationship between reproductive cancers treated conservatively and adverse fetal birth outcomes in subsequent pregnancies.

Fertility preservation in gynecological cancers

For cancers of reproductive system in women, fertility preservation is complex. Fertility is also affected by therapies, however prevention is possible. Radiotherapy affects gonads, uterus, and subsequent pregnancy outcomes in all ages. However, degree and damage depend on dose, irradiation field, and age at the time of exposure. Ovarian transposition is considered if ovarian involvement is unlikely. Gonadotoxic effects of chemotherapy are related to agent's type, cumulative doses, age, and ovarian reserve. Some agents are highly toxic. Rendering follicular development quiescent by suppression of gonadotropins does reduce the ovarian damage. Simple or radical trachelectomy can be used in early cervical cancer. Fertility saving surgery is possible only in early stage low grade epithelial cancers of the ovary, however, in germ cell tumors even in advanced stages it may be possible to preserve fertility. There are no standard recommendations for endometrial cancer. Embryo, oocyte, and ovarian tissue cryopreservation are possible. The human embryo is very resistant to damage. In view of these possibilities, it is advocated that attention to long term health and quality of life in gonadotoxic therapy must be incorporated into plans as early as possible.

Surgical management of epithelial ovarian cancer

Ovarian cancer affects approximately 21,880 women and accounts for over 13,000 deaths annually in the United States. Although survival rates have improved over the past several decades, directly as a result of advances in chemotherapy and surgery, ovarian cancer continues to have high mortality rates. Understanding the multiple roles of surgery throughout the disease course is the focus of this review.

Impact of environmental exposures on ovarian function and role of xenobiotic metabolism during ovotoxicity

The mammalian ovary is a heterogeneous organ and contains oocyte-containing follicles at varying stages of development. The most immature follicular stage, the primordial follicle, comprises the ovarian reserve and is a finite number, defined at the time of birth. Depletion of all follicles within the ovary leads to reproductive senescence, known as menopause. A number of chemical classes can destroy follicles, thus hastening entry into the menopausal state. The ovarian response to chemical exposure can determine the extent of ovotoxicity that occurs. Enzymes capable of bioactivating as well as detoxifying xenobiotics are expressed in the ovary and their impact on ovotoxicity has been partially characterized for trichloroethylene, 7,12-dimethylbenz[a]anthracene, and 4-vinylcyclohexene. This review will discuss those studies, as well as illustrate where knowledge gaps remain for chemicals that have also been established as ovotoxicants.

Clinical outcomes of fertility-sparing treatments in young patients with epithelial ovarian carcinoma

OBJECTIVE

To assess the clinical outcomes of fertility-sparing treatments in young patients with epithelial ovarian carcinoma (EOC).

METHODS

A retrospective study of young EOC inpatients (≤40 years old) was performed during January 1994 and December 2010 in eight institutions.

RESULTS

Data were analyzed from 94 patients treated with fertility-sparing surgery with a median follow-up time of 58.7 months. As histologic grade increased, overall survival (OS) and disease-free survival (DFS) of patients receiving fertility-sparing surgery declined. Neither staging surgery nor laparoscopy of early stage EOC with conservative surgery had a significant effect on OS or DFS. Normal menstruation recommenced after chemotherapy in 89% of the fertility-sparing group. Seventeen pregnancies among twelve patients were achieved by the end of the follow-ups.

CONCLUSIONS

Fertility-sparing treatment for patients with EOC Stage I Grade 1 could be cautiously considered for young patients. The surgical procedure and surgical route might not significantly influence the prognosis. Standard chemotherapy is not likely to have an evident impact on ovarian function or fertility in young patients.

How confident are young adult cancer survivors in managing their survivorship care? A report from the LIVESTRONG™ Survivorship Center of Excellence Network

INTRODUCTION

This study examined the association between sociodemographic, cancer treatment, and care delivery factors on young adult cancer survivors' confidence in managing their survivorship care.

METHODS

Survivors aged 18-39 years (n = 376) recruited from the LIVESTRONG™ Survivorship Center of Excellence Network sites completed a survey assessing self-reported receipt of survivorship care planning, expectations of their providers, and confidence in managing their survivorship care. Multivariate logistic regression identified characteristics of those reporting low confidence in managing their survivorship care.

RESULTS

Mean age was 28 years; mean interval from diagnosis was 9 ± 8 years. Seventy-one percent reported currently attending an oncology survivorship clinic. Regarding survivorship care planning, 33% did not have copies of their cancer-related medical records, 48% did not have a treatment summary, and 55% had not received a survivorship care plan. Seventy percent identified the oncologist as the most important health care provider for decisions regarding test and treatment decisions while 10% reported using a "shared-care model" involving both primary care providers and oncologists. Forty-one percent were classified as having low confidence in managing survivorship care. In multivariate analysis, low confidence was associated with non-white ethnicity and lack of a survivorship care plan (both p < 0.05).

DISCUSSION/CONCLUSIONS

Findings suggest that provision of survivorship care plans for young adult cancer survivors can be used to improve confidence in managing survivorship care, particularly for ethnic minorities.

IMPLICATIONS FOR CANCER SURVIVORS

Survivors should consider advocating for receipt of a survivorship care plan as it may facilitate confidence as a consumer of survivorship care.

Safety of pregnancy after primary breast carcinoma in young women: a meta-analysis to overcome bias of healthy mother effect studies

BACKGROUND

An increased number of women are expected to conceive after the diagnosis of early breast cancer. Most physicians recommend that pregnancy be delayed by 2 to 3 years after diagnosis of early breast cancer, but this recommendation is based on data from trials with small patient cohorts. Furthermore, a healthy mother effect (HME) selection bias may be operative in most of these studies, because women undergoing childbearing after treatment were healthier when compared with the control group.

AIM

To perform a systematic review and meta-analysis of published trials corrected for HME bias so as to assess the effect of pregnancy (at least 10 months after diagnosis) versus no pregnancy on overall survival of primary breast cancer patients less than 45 years.

METHODS

We searched MEDLINE and Thomson Reuters (ISI) Web of Knowledge for eligible studies. From each study we extracted the relative hazard ratio or, if not provided, all the necessary data to impute it. In cases where the duration from diagnosis to pregnancy was not reported, we extracted relevant data to estimate it.

RESULTS

Our electronic search strategy yielded 1623 hits pertaining to 20 potentially eligible studies involving 49,370 premenopausal breast cancer patients. Ten studies were eligible after considering HME potential bias in matching controls. Among these, 9 studies (pregnant 1089, matched-controls 13051) contained data appropriate for analysis. Overall survival was statistically higher among patients who became pregnant compared to controls: fixed effect model estimated pooled hazard ratio for death 0.51 (95% confidence interval: 0.42-0.62). No study heterogeneity was observed: Q = 10.4, P = 0.17; I(2) = 48%.

CONCLUSION

The pooled available evidence indicates that in early breast cancer patients, pregnancy that occurs at least 10 months after diagnosis does not jeopardize prognosis and may actually confer significant survival benefit.

TARGET AUDIENCE

Obstetricians & Gynecologists, Family Physicians.

LEARNING OBJECTIVES

After completing this CME activity, physicians should be better able to assess the effect pregnancy has on long-term survival in primary breast cancer patients under age 45; counsel patients on the safety of pregnancy after breast cancer diagnosis and treatment; and interpret how pregnancy may be associated with improved breast cancer survival.

Xenotransplantation of cryopreserved ovarian tissue from patients with ovarian tumors into SCID mice--no evidence of malignant cell contamination

This study examined the possible presence of malignant cells in ovarian cortex from patients with ovarian tumors after xenografting of the ovarian tissue into severe combined immunodeficiency mice. None of the mice presented symptoms of reintroduced malignancy nor did microscopic and immunohistochemical evaluation of the grafts raise any suspicion of residual malignant disease.

Ultra-conservative fertility-sparing strategy for bilateral borderline ovarian tumours: an 11-year follow-up

BACKGROUND

This is a prospective long-term extension study of a randomized controlled trial aimed to assess the risk-benefit ratio of an ultra-conservative fertility-sparing approach in patients with bilateral borderline ovarian tumours (BOTs).

METHODS

The experimental group (n = 15) was treated with an ultra-conservative surgical approach consisting of bilateral cystectomy, whereas the control group (n = 17) received a less conservative surgery consisting of oophorectomy plus controlateral cystectomy alone. All patients received a complete laparoscopic staging followed by a fertility enhancement programme. Patients who completed childbearing were treated with a non-conservative standard treatment at the first recurrence.

RESULTS

After a follow-up period of 128 (9 interquartile range (IQR); 115-150 range) and 132 (7 IQR; 117-152 range) months for the experimental and control groups, respectively (P = 0.25), the time to first baby-in-arm (P < 0.02) and the relative rate (RR) of baby-in-arm (8.05 [95% confidence interval (CI), 1.20-9.66; P < 0.01]) were significantly lower and higher, respectively, for the experimental compared with the control group. Although the time to first recurrence was significently (P < 0.01) shorter for the experimental group, in the regression analysis the difference did not reach the statistic significance (P = 0.14), and the RR of recurrence (1.23 [95% CI, 0.62-3.17; P = 0.41]) was not significant. Finally the number needed to treat for pregnancy was three, the number needed to harm for radical surgery was only two.

CONCLUSIONS

The ultra-conservative fertility-sparing approach is more effective than the standard approach in terms of reproductive outcomes, but presents a higher oncological risk.

Depression, anxiety and body image after treatment for invasive stage one epithelial ovarian cancer

BACKGROUND

Diagnosis of epithelial ovarian cancer (EOC) in young women has major implications including those to their reproductive potential. We evaluated depression, anxiety and body image in patients with stage I EOC treated with fertility sparing surgery (FSS) or radical surgery (RS). We also investigated fertility outcomes after FSS.

METHODS

A retrospective study was undertaken in which 62 patients completed questionnaires related to anxiety, depression, body image and fertility outcomes. Additional information on adjuvant therapy after FSS and RS and demographic details were abstracted from medical records. Both bi- and multivariate regression models were used to assess the relationship between demographic, clinical and pathological results and scores for anxiety, depression and body image.

RESULTS

Thirty-nine patients underwent RS and the rest, FSS. The percentage of patients reporting elevated anxiety and depression (subscores > or = 11) were 27% and 5% respectively. The median (interquartile range) score for Body Image Scale (BIS) was 6 (3-15). None of the demographic or clinical factors examined showed significant association with anxiety and BIS with the exception of 'time since diagnosis'. For depression, post-menopausal status was the only independent predictor. Among those 23 patients treated by FSS, 14 patients tried to conceive (seven successful), resulting in seven live births, one termination of pregnancy and one miscarriage.

CONCLUSION

This study shows that psychological issues are common in women treated for stage I EOC. Reproduction after FSS is feasible and led to the birth of healthy babies in about half of patients who wished to have another child. Further prospective studies with standardised instruments are required.

Surviving childhood and reproductive-age malignancy: effects on fertility and future parenthood

Annually, more than 50,000 cancer diagnoses are made in the USA in patients under the age of 35 years. Despite this staggering statistic, medical advancements have substantially improved survival rates. Thus, for both male and female patients with cancer, quality-of-life issues, such as fertility preservation and parenthood, have become an essential component of treatment. Unfortunately, many of the treatments to eradicate malignant processes can also compromise reproductive function. In these cases, fertility preservation should be discussed and initiated with early treatment planning, to allow the best chance for future parenthood, when appropriate. The effects of cancer and cancer treatments on fertility and future parenthood, including health risks for patients, their gametes, and offspring are discussed.

Psychological aspects of fertility preservation in men and women affected by cancer and other life-threatening diseases

BACKGROUND

With advances in treatment, the number of young cancer survivors who may benefit from fertility preservation is growing. The aim of this study was to review the literature investigating psychological aspects of fertility issues and fertility preservation in patients undergoing fertility-compromising therapy for cancer or other life-threatening diseases, previous to or during their reproductive lifespan.

METHODS

Articles were identified in PubMed, Embase and PsycLIT as well as manually retrieved from literature citations for the time period from 1999 to 2008. Inclusion criteria were (i) qualitative or quantitative design, (ii) focus on patients previous to or during their reproductive lifespan and (iii) dealing with aspects such as (1) impact of fertility issues in cancer patients or (2) health professionals' and/or patients' attitudes towards fertility preservation or (3) counselling.

RESULTS

Twenty-four studies were identified. According to the studies on aspect (1), fertility is an important issue for cancer patients. Health professionals as well as patients and parents consider fertility preservation as an important option for young cancer patients; all parties involved, however, were noted to have knowledge and information deficits. Patients recalling counselling about the impact of cancer treatment on fertility ranged from 34% to 72%. Counselling is far from being offered globally to all patients at risk, and providing information seems to be selective.

CONCLUSIONS

The existing literature demonstrates the need for and the limits of current counselling. Future research should target the means to facilitate the decision-making process for patients and health professionals.

Medical and psychosocial aspects of fertility after cancer

Survival for cancer has improved significantly in the last 25 years with excellent overall 5- and 10-year survival rates. Hence, the majority of young women diagnosed with cancer can expect to live for decades, making quality of life issues such as fertility increasingly important. Risks of infertility vary based on the chemotherapy and treatments employed, as well as a woman's age. In general, younger women are less likely to experience permanent amenorrhea than older women, but even women who continue to menstruate have a greatly increased risk of premature menopause. Options for patients with cancer entering chemotherapy treatment, who wish to preserve fertility range from clinically well-established techniques such as embryo cryopreservation to more experimental techniques such as ovarian tissue cryopreservation. Pregnancy does not appear to increase the risk of cancer recurrence. Discussions of fertility issues in premenopausal women diagnosed with cancer present important challenges to the provider and to the patient. However, failure to discuss these options adequately can have lasting negative consequences on a woman's quality of life. Physician education interventions should seek to improve the knowledge of fertility preservations options, and of locally and nationally available resources.

Cancer and fertility preservation in females: where we stand and where we are heading

It is estimated that, in 2010, one in every 250 adults will be a childhood cancer survivor. This review discusses the impact of current cancer treatment on fertility potential and the assisted-reproduction innovations available today for the most common cancers in young women. As the emerging discipline of fertility preservation is steadily attracting increasing interest, developments in the near future promise to be very exciting. However, in everyday routine work, better interdisciplinary cooperation between gynecological and pediatric oncologists, surgeons, immunologists and endocrinologists is necessary so that individualized options for fertility preservation can be offered in advance of surgical procedures or cancer treatments.

Fertility drugs and risk of ovarian cancer: dispelling the myth

PURPOSE OF REVIEW

Worldwide 50-80 million people suffer from infertility. Assisted reproductive technology has provided a way of overcoming infertility and childlessness. The current article will focus on data linking infertility and its treatment to ovarian cancer.

RECENT FINDINGS

Ovarian cancer risks associated with fertility drug treatment are encouraging, but not decisive. In view of the limited ability to evaluate drug effects on borderline tumors, given their rare occurrence, studies involving patient reports of prior drug exposures have noted an elevated risk of borderline tumors associated with fertility drugs. Nevertheless, the risk of invasive ovarian cancer appears to be restricted to those women who remain childless despite the infertility treatment.

SUMMARY

As long as doubt persists, it might be advisable to reflect on a few clinical recommendations: identify high-risk infertile patients for ovarian cancer, investigate preexisting cancer before fertility treatment, inform patients regarding potential risks, obtain an informed consent, avoid exposure to long periods of ovulation induction cycles that are given before patients are referred for in-vitro fertilization and embryo transfer for women at greater risk and monitor women who have been treated with these drugs, especially those who failed to conceive, regularly and thoroughly.
