Oncology Physicians' Perspectives on Practices and Barriers to Fertility Preservation and the Feasibility of a Prospective Study of Pregnancy After Breast Cancer

Oncofertility and Pregnancy in Adolescent and Young Adult Cancers: Physicians' Knowledge and Preferences in India

PURPOSE

The treatment outcomes of adolescent and young adult (AYA) cancers have improved with advanced oncology care. Hence, fertility preservation (FP) and post-therapy pregnancies (PTPs) become vital issues.

MATERIALS AND METHODS

An online survey link with 17 questions regarding oncofertility and PTPs was circulated among oncologists to assess the knowledge, understand the oncofertility care patterns, and seek suggestions to improve oncofertility services.

RESULTS

The median age of 179 respondents, predominantly medical oncologists (68.7%), was 37 years (IQR, 10; range, 29-74), working in academic centers (39%) having a median experience of 4 years (IQR, 4; range, 1-42); 23 (12.8%) had dedicated AYA cancer units. Although a quarter (19%-24%) of respondents discussed fertility issues in >90% of AYA patients with cancer, only a tenth (8%-11%) refer >90% for FP, with significantly higher (P < .05) discussions and referrals in males and by more experienced oncologists (P < .05). Forty-six (25.6%) were not well versed with international guidelines for FP. Most (122, 68.1%) oncologists knew about the referral path for semen cryopreservation; however, only 46% were knowledgeable about additional complex procedures. One hundred and ten (61.5%) oncologists never or rarely altered the systemic treatment for FP. Prominent barriers to FP were ignorance, lack of collaboration, and fear of delaying cancer treatment. Lead thrust areas identified to improve FP practices are education, and enhanced and affordable access to FP facilities. Seventy-four (41.3%) respondents knew about international guidelines for PTPs; however, only half (20%) of them often monitored fertility outcomes in survivors. Oncologists have conflicting opinions and uncertainties regarding pregnancy safety, assisted reproductive techniques, breastfeeding, and pregnancy outcomes among survivors.

CONCLUSION

Oncologists are uncertain about the guidelines, FP practices, referral pathways, and PTPs. Multipronged approaches to improve awareness and provision for affordable oncofertility facilities are needed to enhance AYA cancer outcomes in India, which will be applicable to other low- and middle-income countries too.

Reproduction in life and death: should cancer patients with a poor prognosis be offered fertility preservation interventions?

In the context of a cancer diagnosis, fertility preservation interventions are used to mitigate the potential impact of gonadotoxic cancer treatment upon fertility. They provide patients with cancer the option to freeze their reproductive material to have their own biological child following treatment. The evidence suggests some clinicians are less likely to have fertility preservation discussions with patients who have an aggressive or metastatic cancer which has a poor prognosis. Although this is contrary to current policy recommendations, there is a lack of guidance relating to offering fertility preservation in the context of a poor prognosis to support clinicians. Controversy surrounds posthumous reproduction, and whether the wishes of the cancer patient, when living and deceased should take precedence over others' wellbeing. We consider the question of whether cancer patients with a poor prognosis should be offered FP from an ethics perspective. We structure the paper around key arguments to which multiple ethical principles might pertain, first establishing a central argument in favour of offering fertility preservation based on respect for autonomy, before exploring counterarguments. We conclude by proposing that a defeasible assumption should be adopted in favour of offering fertility preservation to all cancer patients who might benefit from it. It is important to recognise that patients could benefit from fertility preservation in many ways, and these are not limited to having a parenting experience. The burden of proof rests on the clinician in collaboration with their multi-disciplinary team, to show that there are good grounds for withholding the offer.

Fertility Preservation in Young Women With Breast Cancer: A Review

Fertility preservation is a major concern in young patients diagnosed with breast cancer and planning to receive multimodality treatment, including gonadotoxic chemotherapy with or without age-related decline through long-term endocrine therapy. Most breast cancer patients undergo multimodality treatments; many short-term and long-term side effects arise during these therapies. One of the most detrimental side effects is reduced fertility due to gonadotoxic treatments with resultant psychosocial stress. Cryopreservation of oocytes, embryos, and ovarian tissue are currently available fertility preservation methods for these patients. As an adjunct to these methods, in vitro maturation or gonadotropin-releasing hormone agonist could also be considered. It is also essential to communicate well with patients in the decision-making process on fertility preservation. It is essential to refer patients diagnosed with breast cancer on time to fertility specialists for individualized treatment, which may lead to desirable outcomes. To do so, a multimodal team-based approach and in-depth discussion on the treatment of breast cancer and fertility preservation is crucial. This review aims to summarize infertility risk related to currently available breast cancer treatment, options for fertility preservation and its details, barriers to oncofertility counseling, and psychosocial issues.

Fertility discussions and concerns in childhood cancer survivors, a systematic review for updated practice

PURPOSE

To provide ways to improve the clinical practice of fertility preservation (FP) for children, adolescents, and young adults (AYA) with cancer.

DESIGN

A systematic research of online databases was undertaken in March 2020 following the PRISMA criteria, including Medline and Web of Science.

RESULTS

Fifty-nine articles were included. Surveys, interviews, and focus groups were used to collect data from patients, parents, and health care providers (HCPs). Four themes worth exploring emerged: (a) what do patients and professionals think of and know about FP? (b) what makes the fertility discussion happen or not? (c) what, retrospectively, led to FP being pursued or not? and (d) how do patients and HCPs feel about fertility issues?

CONCLUSION

A minority of AYAs preserve their fertility (banking assay for 45% of boys and 23% of girls). Yet fertility concerns have a significant impact on the quality of life of young cancer survivors. Although recommendations and guidelines regarding FP are available internationally, there are no specific guidelines as to how to conduct fertility counseling for children and adolescents. Some barriers are not removable, such as a poor prognosis of an obvious severe disease, time constraints for starting treatment, and cultural and religious beliefs. In response to aspects hindering patients and families to be receptive to any discussion at the time of diagnosis, psychological support could reduce the level of emotional distress and help restore a degree of open-mindedness to open a window for discussion. Moreover, as the lack of knowledge of professionals about fertility is frequently pointed out as a limiting factor for fertility discussion, reinforcing professional training regarding FP could be proposed to promote fertility discussion and eventually referral for FP.

Knowledge, attitudes, and behaviors toward fertility preservation in patients with breast cancer: A cross-sectional survey of physicians

Background

Fertility is an important issue for young women with breast cancer, but studies about physicians' knowledge, attitudes, and practices toward fertility preservation (FP) are largely based on Western populations and do not reflect recent international guidelines for FP. In this international study, we aimed to assess the knowledge, attitudes, and practices of physicians from South Korea, other Asian countries, and Latin America toward FP in young women with breast cancer, and identify the related barriers.

Methods

The survey was conducted anonymously among physicians from South Korea, other Asian countries, and Latin America involved in breast cancer care between November 2020 and July 2021. Topics included knowledge, attitudes, and perceptions toward FP; practice behaviors; barriers; and participant demographics. We grouped related questions around two main themes-discussion with patients about FP, and consultation and referral to a reproductive endocrinologist. We analyzed the relationships between main questions and other survey items.

Results

A total of 151 physicians completed the survey. Most participants' overall knowledge about FP was good. More than half of the participants answered that they discussed FP with their patients in most cases, but that personnel to facilitate discussions about FP and the provision of educational materials were limited. A major barrier was time constraints in the clinic (52.6%). Discussion, consultations, and referrals were more likely to be performed by surgeons who primarily treated patients with operable breast cancer (FP discussion odds ratio [OR]: 2.90; 95% confidence interval [CI]: 1.24-6.79; FP consultation and referral OR: 2.98; 95% CI: 1.14-7.74). Participants' knowledge and attitudes about FP were significantly associated with discussion, consultations, and referrals.

Conclusion

Physicians from South Korea, other Asian countries, and Latin America are knowledgeable about FP and most perform practice behaviors toward FP well. Physicians' knowledge and favorable attitudes are significantly related to discussion with patients, as well as consultation with and referral to reproductive endocrinologists. However, there are also barriers, such as limitations to human resources and materials, suggesting a need for a systematic approach to improve FP for young women with breast cancer.

Prognostic effect of subsequent childbirth after the diagnosis of breast cancer using propensity score matching analysis

BACKGROUND

Among younger patients, one of the important concerns is whether they can give birth safely. Although previous studies have investigated this topic, many aspects remain unclear owing to potential biases. We aimed to evaluate the prognostic effect of subsequent childbirth after the diagnosis using propensity score matching.

METHODS

A single-center retrospective cohort study was conducted. This study included patients aged ≤ 45 years, diagnosed with breast cancer between 2005 and 2014. Patients with and without subsequent childbirth were assigned to the childbirth and non-childbirth cohorts, respectively. Relapse-free survival (RFS) and overall survival (OS) of the childbirth cohort were compared with those of the non-childbirth cohort. The covariates in the propensity score model included age, tumor size, node status, number of preceding childbirths before the diagnosis, estrogen receptor, and human epidermal growth factor receptor 2 status.

RESULTS

104 patients with childbirth and 2250 without childbirth were assigned to the respective cohorts. At a median follow-up of 82 months, the childbirth cohort showed a significantly longer RFS than the non-childbirth cohort (HR = 0.469 [0.221-0.992]; p = 0.047). There was no significant difference in the OS (HR = 0.208 [0.029-1.494]; p = 0.119). After matching, subsequent childbirth was not significantly associated with RFS (HR = 0.436 [0.163-1.164], p = 0.098) and OS (HR = 0.372 [0.033-4.134], p = 0.402).

CONCLUSIONS

Subsequent childbirth was not associated with an increased risk of relapse and mortality. It is important to make younger patients aware of these novel findings and aid them in their decision-making.

Relapse Rates and Disease-Specific Mortality Following Procedures for Fertility Preservation at Time of Breast Cancer Diagnosis

Question

Is fertility preservation at time of breast cancer diagnosis associated with any increased risk of disease-specific relapse or mortality?

Findings

In this population-based Swedish nationwide cohort study that included 1275 women with breast cancer, fertility preservation at time of breast cancer diagnosis was not statistically significantly associated with any increased risk of disease-specific mortality or relapse.

Meaning

Findings of this study support the safety of fertility preservation in women with breast cancer, which is highly relevant for reproductive counseling of women with breast cancer diagnosed at a young age.

Importance

Breast cancer (BC) is the most common indication for fertility preservation (FP) in women of reproductive age. Procedures for FP often include hormonal stimulation, but current data are scarce regarding whether using hormonal stimulation for FP is associated with any deterioration in BC prognosis.

Objective

To investigate the risk of disease-specific mortality and relapse in women who underwent FP with or without hormonal stimulation compared with women who did not at time of BC diagnosis.

Design, Setting, and Participants

This Swedish nationwide prospective cohort study was conducted to assess the safety of hormonal and nonhormonal FP procedures indicated by BC in Sweden from January 1, 1994, through June 30, 2017. Women were identified from any of the regional FP programs located at Swedish university hospitals. A total of 425 women were found to have undergone FP, and 850 population comparators who had not undergone FP were sampled from regional BC registers and matched on age, calendar period of diagnosis, and region. Relapse-free survival was assessed in a subcohort of 241 women who underwent FP and 482 women who had not, with complete data. Nationwide demographic and health care registers provided data on outcome, disease- and treatment-related variables, and socioeconomic characteristics. Data analyses were performed between November 2021 and March 2022 and completed in June 2022.

Main Outcomes and Measures

Relapse and disease-specific mortality after a diagnosis of BC.

Results

The final study population included 1275 women (mean [SD] age, 32.9 [3.8] years) at the time of BC diagnosis. After stratification by the matching variables age, calendar period, and region, and adjustment for country of birth, education, parity at diagnosis, tumor size, number of lymph node metastases, and estrogen receptor status, disease-specific mortality was similar in women who underwent hormonal FP (adjusted hazard ratio [aHR], 0.59; 95% CI, 0.32-1.09), women who underwent nonhormonal FP (aHR, 0.51; 95% CI, 0.20-1.29), and women who were not exposed to FP (reference). In a subcohort with detailed data on relapse, adjusted rate of disease-specific mortality and relapse were also similar among the groups who underwent hormonal FP (aHR, 0.81; 95% CI, 0.49-1.37), underwent nonhormonal FP (aHR, 0.75; 95% CI, 0.35-1.62), and were not exposed to FP (reference).

Conclusions and Relevance

In this cohort study, FP with or without hormonal stimulation was not associated with any increased risk of relapse or disease-specific mortality in women with BC. Results of this study provide much needed additional evidence on the safety of FP procedures in women with BC and may influence current health care practice to the benefit of young women with BC who wish to preserve their fertility.

Practices, Attitudes, and Knowledge Among Healthcare Providers and Oncologists in China Regarding Male Fertility Preservation

Objective

The purpose of this study was to help to promote a better understanding of the male fertility preservation status in China.

Methods

In this cross-sectional survey, 1,912 healthcare providers and oncologists were surveyed anonymously using 16 questions carried out at community oncology practices in China from September 2018 to April 2021. 16 questions were designed to evaluate their knowledge on male fertility preservation in cancer patients, assess the factors they considered when deciding whether to discuss male fertility preservation with their patients.

Results

Among the 1,912 healthcare providers (42.2% male), 1,713 (89.6%) considered that patients with cancer should be recommended for fertility preservation. 1,264 (66.1%) respondents were aware of male fertility preservation, but only 248 (13.0%) respondents knew the correct institutions. Whether a healthcare provide recommended fertility preservation to their patients depended on the provider's educational background, professional qualifications, hospital grade, area, department, and age. Among the healthcare providers, the three main factors for not recommending fertility preservation for patients with cancer were lack of suitability of the patient for fertility (28.2%), lack of knowledge of fertility preservation (28.6%), and lack of knowledge concerning the institutes that provide fertility preservation (25.4%).

Conclusion

Despite this, healthcare providers and oncologists in China showed a positive attitude toward fertility preservation in patients with cancer. Hence, the education of physicians should include fertility preservation, with the aim of increasing their knowledge and awareness. There should be more collaboration between oncologists and reproductive medicine specialists.

Knowledge, Practice, and Attitudes of Physicians in Low- and Middle-Income Countries on Fertility and Pregnancy-Related Issues in Young Women With Breast Cancer

Fertility and pregnancy-related issues are highly relevant for young (≤ 40 years) patients with breast cancer. Limited evidence exists on knowledge, practice, and attitudes of physicians from low- and middle-income countries (LMICs) regarding these issues.

Oncofertility care: A qualitative study to understand personal perspectives and barriers in the multidisciplinary breast care team in Taiwan

Background:

Previous studies indicate significant gaps exist in current practices and perceptions of oncofertility care.

Objectives:

We aim to understand the clinical experience regarding oncofertility care among health providers in a multidisciplinary breast care team.

Methods:

A qualitative, descriptive study was conducted. Data were collected through in-depth interviews with 16 health care providers who worked in a hospital in Taipei. Verbatim transcriptions were analyzed using constant analysis methods.

Results:

Health care providers’ experiences regarding fertility care for reproductive-age women with breast cancer were divided into two themes: personal perspectives and barriers. Personal perspectives consisted of six subthemes including empathizing with the patient’s suffering during the diagnosis and treatment, safety as a prerequisite, satisfying the women’s needs, respecting the women’s choice, questioning women’s ability to raise children, and returning to family life. There were also six subthemes under barriers. These subthemes were poor communication among the multidisciplinary team, lack of initial screening, insufficient support in the women’s families, treatment considerations, lack of evidence-based information regarding oncofertility, and non-follow-up protocol.

Conclusion:

Nurses should evaluate the fertility needs of women with cancer and identify potential gaps during oncofertility care. Education strategies and tactics should be improved in order to overcome difficulties arising from health care providers’ personal perspectives and barriers to the provision of optimal fertility care in women with cancer.

Attitudes and practices about fertility preservation discussions among young adults with cancer treated at a comprehensive cancer center: patient and oncologist perspectives

BACKGROUND

Young adults (YAs, ages 18-39) diagnosed with cancer face multiple challenges that affect their health-related quality of life, including the potential for cancer-related infertility. Providing information about the risk of infertility and options to maintain fertility is critical for YAs who are newly diagnosed. However, barriers to effective communication exist for oncologists and their patients. The purpose of this study was to interview medical oncologists and YAs from the same cancer center to examine attitudes and practices about fertility preservation.

METHODS

Semi-structured interviews were conducted with medical oncologists (N=12) and YAs within 2 years post-treatment (N=24), representing the most common cancers affecting YAs. Interviews were audio-recorded, transcribed, and coded using qualitative methodologies with the analysis software NVivo 10.

RESULTS

Twelve oncologists (50% female, 67% <50 years) and 24 YAs (67% female, M=29 years) completed interviews. Common themes across oncologist and YA interviews were the roles of cancer type or stage and patient interest or parity in influencing the decision. The most important factor for YAs was to receive accurate, in-depth information. Unique themes for oncologists focused on clinical aspects of their patient's disease. For YAs, they shared about the emotional impact of cancer-related infertility and desire for support from trusted others.

CONCLUSIONS

Results provide a better understanding of the attitudes and practices about fertility preservation discussions among YAs. Given the common factors affecting fertility preservation decisions, models of shared decision-making may be ideal for YAs and oncologists. Future interventions should explore tailored applications of this approach for YAs newly diagnosed with cancer.

Evidenced-based practice of decision-making process in oncofertility care among registered nurses: A qualitative study

AIM

The purpose of our study was to construct the context of the nursing action/role in oncofertility care.

DESIGN

Qualitative research.

METHODS

We applied grounded theory to guide the qualitative study. Data were collected through in-depth interviews with 12 nurses in Taipei. The data were collected from August 2018 to February 2019.

RESULTS

The core theme that described the role of nurses' decision-making in oncofertility care focused on understanding oncofertility from the self to the other. Care roles or actions in oncofertility that involved the process of psychological cognition were divided into four dimensions: perceiving the patient's changes and needs, triggering the self's emotions, empathizing with patient's situations and introspective care roles. Nurses who had experienced the phase of empathizing with the patient's situations developed more diverse roles and had positive actions toward oncofertility care. Based on the psychological changes for oncofertility decision-making process, implementing contextual training in oncofertility could help nurses create more positive actions in oncofertility care.

The Effect of Subsequent Pregnancy on Prognosis in Young Breast Cancer Patients (≤35 Years Old) According to Hormone Receptor Status

Purpose

We aimed to examine the effect of pregnancy on prognosis in young breast cancer (YBC) patients with hormone receptor (HR) positive after surgery and the safety of interrupting endocrine therapy (ET).

Methods

A retrospective cohort study was performed in patients who became pregnant after BC surgery under the age of 35 and were matched (1:4) to nonpregnant patients from 2006 to 2014. The primary endpoints were disease-free survival (DFS) and overall survival (OS) in HR-positive BC patients, and the secondary endpoints were DFS and OS in HR-negative BC patients and the whole population. Subgroup analyses included the DFS of patients who became pregnant within 5 years after surgery and DFS according to the ET interval time (≤ 30 months v > 30 months) in the pregnant group.

Results

A total of 1323 YBC patients were collected in our study, which included 68 pregnant patients and 264 matched nonpregnant patients. There were no statistically significant differences in DFS and OS among HR-positive patients (P=0.657, P=0.250, respectively) and the whole population (P=0.058, P=0.152, respectively). A BC pregnancy interval ≤ 5 years showed a better DFS (P=0.042), and an ET interval ≤ 30 months had a worse DFS (P = 0.01).

Conclusion

This study did not observe a worse prognosis in patients with HR-positive disease who became pregnant after BC surgery, and an ET interval less than 30 months in pregnant patients led to a worse outcome. Patients were able to become pregnant within 5 years after surgery.

Survey of professionals on breast cancer, fertility preservation and pregnancy in Argentina

Introduction

Medical knowledge regarding preservation of fertility and pregnancy in patients with breast cancer (BC) is of interest. We, therefore, decided to conduct a survey on this issue among professionals involved in the treatment of BC in Argentina.

Materials and methods

A survey was conducted and sent by email to 3,412 contacts in the Argentine Mastology Society (Sociedad Argentina de Mastología, or SAM) database, with responses from 396 physicians. The survey design was based on the Lambertini 2017 survey. To the author's knowledge, it is the first Argentine survey to address this issue.

Results

The frequency with which the impact of cancer treatment on the fertility of young patients was addressed by the respondent and referred to a fertility specialist was 'always' and 'almost always' in 86.8% and 78.5% of cases, respectively.

Conclusions

The level of knowledge is comparable to the data presented by other surveys. Membership in a Mastology Unit was associated with more current treatment. Continued work on the training of professionals is necessary to facilitate communication, information and guidance of patients of childbearing age who are going to have cancer treatment in order to advise them on fertility preservation, as well as the possibility of pregnancy after diagnosis of BC, and to be able to provide better care to those with BC associated with pregnancy.

Does Use of Neoadjuvant Chemotherapy Affect the Decision to Pursue Fertility Preservation Options in Young Women with Breast Cancer?

BACKGROUND

The American Society of Clinical Oncology guidelines recommend early referral to reproductive endocrinology and infertility (REI) specialists for young women diagnosed with breast cancer. Current practice patterns demonstrate an increased utilization of neoadjuvant chemotherapy (NAC). We evaluated premenopausal women with breast cancer after consultation with a Fertility Nurse Specialist (FNS) and determine factors associated with referral to REI specialists.

METHODS

This retrospective review included all premenopausal women diagnosed at our institution with stage 0-III unilateral breast cancers between 2009 and 2015 who completed an FNS consultation. Clinicopathologic features and factors associated with referral to REI after FNS consultation were analyzed.

RESULTS

A total of 334 women were identified. Median age was 35 years (interquartile range 32-38). The majority of women were single (n = 198, 59.3%) and nulliparous (n = 239, 71.6%). REI referrals were common (n = 237, 71.0%). The Breast Surgery service was the most frequent referring service (n = 194, 58.1%), with significantly more REI referrals compared to Breast Medicine and Genetics services (p = 0.002). Nulliparity was associated with REI referral (p < 0.0001). Adjuvant chemotherapy (p = 0.003) was associated with pursuing REI referral, whereas NAC (p < 0.001) was associated with declining REI referral.

CONCLUSIONS

Most women elected to consult with an REI specialist, confirming strong interest in fertility preservation among premenopausal women with breast cancer. However, women receiving NAC more frequently declined referral to REI, suggesting that the need to start NAC may influence decisions regarding fertility preservation. With increasing utilization of NAC, our study supports the need for further counseling and education regarding fertility preservation for women undergoing NAC.

A Survey Study Reveals the Positive Impact of Oncofertility Knowledge and Attitude on Oncofertility Practice Among Oncologists in China

Purpose: The advances of early cancer diagnoses and treatment methods allow many adolescent and young adult-aged cancer patients to live long lives after having cancer. There is a rising concern regarding cancer treatment-induced reproductive toxicities and infertility. Oncologists are the first line of medical professionals interacting with cancer patients and playing essential roles in oncofertility practice. This study aimed to assess the oncofertility knowledge, attitude, and practice of oncologists in China. Methods: We created an online questionnaire survey to examine 927 Chinese oncologists' demographics, knowledge, attitude, experience, and practice regarding young female cancer patients' infertility risk and fertility preservation. Results: Results showed that there is an inadequate oncofertility knowledge among surveyed oncologists, which was affected by oncologists' demographic background of education level, clinical title, and working experience. The majority of surveyed oncologists (84.8%-88.7%) held a positive attitude on young female cancer patients' infertility risk and their fertility preservation demand, but their attitude was impacted by marriage status and patients risk of cancer recurrence. Only 11.8% of surveyed oncologists often referred their patients for fertility preservation, while 66.3% and 21.9% of them have referred once or never, respectively. The oncologists' oncofertility practice was not correlated with their demographic background but was significantly influenced by their oncofertility knowledge and attitude. Conclusion: Our study demonstrates that there is an urgent unmet need to improve oncologists' oncofertility knowledge, attitude, and practice in China as well as remove the communication barrier between oncologists and fertility specialists.

Estimation of historical control rate for a single arm de-escalation study - Application to the POSITIVE trial

BACKGROUND

Although randomized controlled clinical trials are optimal to evaluate the effect of an experimental therapy, single-arm trials are required whenever randomization is unethical or not feasible, such as de-escalation studies. We propose using prospectively identified historical controls to place results of single-arm, de-escalation trials into context.

METHODS

POSITIVE is a prospective, single-arm study in young women with hormone-receptor-positive early breast cancer to determine if temporarily interrupting adjuvant endocrine therapy in order to become pregnant increases the risk of a breast cancer event. After 272 women enrolled in POSITIVE, we identified a cohort of 1499 SOFT/TEXT patients potentially eligible to enroll in POSITIVE who did not interrupt endocrine therapy. Method I used the SOFT/TEXT cohort to calculate annualized hazard rates by a piecewise exponential model. Method II used the SOFT/TEXT cohort to group-match SOFT/TEXT patients to POSITIVE patients; sample sets of SOFT/TEXT patients were randomly drawn 5000 times to obtain sets having patient, disease, and treatment characteristics more balanced with POSITIVE participants.

RESULTS

Compared with SOFT/TEXT, POSITIVE participants were younger, less likely to be overweight/obese, had fewer positive nodes, and fewer received aromatase inhibitor or chemotherapy. The estimated 3-year breast cancer free interval event rates were 9.5% (95% CI: 7.9%,11.1%) for Method I and 9.4% (95% CI: 7.8%,10.9%) for Method II, compared with 5.8% initially assumed when POSITIVE was designed.

CONCLUSION

External control datasets should be identified before launching single-arm, de-escalation trials and methods applied during their conduct to provide context for interim monitoring and interpretation of the final analysis.

COVID-19 and assisted reproductive technology services: repercussions for patients and proposal for individualized clinical management

The prolonged lockdown of health services providing high-complexity fertility treatments -as currently recommended by many reproductive medicine entities- is detrimental for society as a whole, and infertility patients in particular. Globally, approximately 0.3% of all infants born every year are conceived using assisted reproductive technology (ART) treatments. By contrast, the total number of COVID-19 deaths reported so far represents approximately 1.0% of the total deaths expected to occur worldwide over the first three months of the current year. It seems, therefore, that the number of infants expected to be conceived and born -but who will not be so due to the lockdown of infertility services- might be as significant as the total number of deaths attributed to the COVID-19 pandemic. We herein propose remedies that include a prognostic-stratification of more vulnerable infertility cases in order to plan a progressive restart of worldwide fertility treatments. At a time when preventing complications and limiting burdens for national health systems represent relevant issues, our viewpoint might help competent authorities and health care providers to identify patients who should be prioritized for the continuation of fertility care in a safe environment.

Fertility preservation in breast cancer with case-based examples for guidance

With more young breast cancer survivors, a trend toward having children later in life, and improvements in assisted reproductive technology (ART), fertility preserving techniques are of growing importance prior to initiation of gonadotoxic treatments. The American Society for Clinical Oncology (ASCO) updated their Fertility Preservation in Patients with Cancer guidelines in April of 2018. ASCO continues to recognize oocyte and embryo cryopreservation as standard practice for women interested in preserving fertility and sperm cryopreservation as standard practice for men. ASCO has clarified their statement on ovarian suppression during chemotherapy as an option when standard methods are unavailable but should not be used as the sole method of fertility preservation (FP) due to conflicting evidence. ASCO also updated their statement on ovarian tissue cryopreservation, which is still labeled experimental but ASCO acknowledges that it can restore global ovarian function and could be of use in specific patients. The NCCN's Version 1.2018 Clinical Practice Guidelines® for treatment of breast cancer include fertility counseling as part of their work-up in all types of breast cancer for premenopausal women.The purpose of this review is to explain the indications and evidence for the different methods of FP for young breast cancer patients in accordance with ASCO and NCCN guidelines. The guidance will then be applied to three theoretical clinical cases in order to highlight actual use in clinical practice.

Infant feeding among women with a history of breast cancer

PURPOSE

Health professional organizations recommend exclusive breastfeeding for 6 months, but there are mothers, such as those with a history of breast cancer, who are unable to exclusively provide their milk for their infants. Minimal research has been published on mothers' experience with lactation, breastfeeding, and bottle-feeding after breast cancer. This study explored mothers' perspectives of infant feeding after a history of breast cancer.

METHODS

Qualitative interviews were completed with 20 mothers who had experience with infant feeding after breast cancer, including exclusive breastfeeding, partial provision of human milk with formula supplementation, and exclusive formula feeding.

RESULTS

Mothers shared their perceptions, barriers, and experiences of infant feeding. Four themes were identified: miracle of motherhood after breast cancer, medical misinformation or no available information contributing to the exacerbation of mothers' worries, post-breast-cancer feeding challenges, and desire for infant-feeding support rather than pressure.

CONCLUSIONS

Mothers who have had breast cancer and have since given birth face specific challenges to infant feeding which are compounded by limited resources and knowledge among healthcare providers. Findings of the study highlight the importance of healthcare professionals becoming more educated to provide adequate support and evidence-based information on lactation and infant feeding for women with a history of breast cancer.

IMPLICATIONS FOR CANCER SURVIVORS

Understanding the experiences of women who have given birth after breast cancer can help women in similar situations know that they are not alone, identify resources, access peer support, and seek evidence-based infant feeding advice from healthcare providers involved in their care.

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.
