Motivation for giving birth after breast cancer

Pregnancy in a Young Patient with Metastatic HER2-Positive Breast Cancer-Between Fear of Recurrence and Desire to Procreate

Breast cancer is the most frequent neoplasm among women and the second leading cause of death by cancer. It is the most frequent cancer diagnosed during pregnancy. Pregnancy-associated breast cancer is defined as breast cancer that is diagnosed during pregnancy and/or in the postpartum period. Data about young women with metastatic HER2-positive cancer who desire a pregnancy are scarce. The medical attitude in these clinical situations is difficult and nonstandardized. We present the case of a 31-year-old premenopausal woman diagnosed in December 2016 with a stage IV Luminal HER2-positive metastatic breast cancer (pT2 N0 M1 hep). The patient was initially treated by surgery in a conservative manner. Postoperatively, the presence of liver metastases was found by CT investigation. Consequently, line I treatment (docetaxel l75 mg/m² iv; trastuzumab 600 mg/5 mL sq) and ovarian drug suppression (Goserelin 3.6 mg sq at 28 days) was administered. After nine cycles of treatment, the patient's liver metastases had a partial response to the therapy. Despite having a favorable disease evolution and a strong desire to procreate, the patient vehemently refused to continue any oncological treatment. The psychiatric consult highlighted an anxious and depressive reaction for which individual and couple psychotherapy sessions were recommended. After 10 months from the interruption of the oncological treatment, the patient appeared with an evolving pregnancy of 15 weeks. An abdominal ultrasound revealed the presence of multiple liver metastases. Knowing all the possible effects, the patient consciously decided to postpone the proposed second-line treatment. In August 2018, the patient was admitted in the emergency department with malaise, diffuse abdominal pain and hepatic failure. Abdominal ultrasound found a 21-week-old pregnancy which had stopped in evolution, multiple liver metastases and ascites in large quantity. She was transferred to the ICU department where she perished just a few hours later. Conclusions/Discussion: From a psychological standpoint, the patient had an emotional hardship to make the transition from the status of a healthy person to the status of a sick person. Consequently, she entered a process of emotional protection of the positive cognitive distortion type, which favored the decision to abandon treatment and try to complete the pregnancy to the detriment of her own survival. The patient delayed the initiation of oncological treatment in pregnancy until it was too late. The consequence of this delay in treatment led to the death of the mother and fetus. A multidisciplinary team worked to provide this patient with the best medical care and psychological assistance throughout the course of the disease.

Oncologists’ Knowledge, Practice and Attitude toward Fertility Preservation: A National Survey

Background: Improved chemotherapy and radiotherapy treatment protocols, fortunately, increased the rates of cancer survivors over the years. However, these treatments may result in infertility or subfertility. Oncologists are considered the gateway for knowledge about cancer and its treatments’ effects. Several studies showed that many oncologists do not discuss fertility preservation with their patients. This study aimed to explore the perspective of oncologists in Oman on fertility preservation. Methods: A cross-sectional study of physicians and surgeons dealing with patients with cancer was conducted from June 2021 to December 2021. A standardized and validated questionnaire was used to collect data. Results: Participants reported that they are knowledgeable about sperm cryopreservation and gonadotropin-releasing hormone agonists use but not other methods of fertility preservation. About 94% of the participants reported that they need more knowledge about fertility preservation. More than half of the participants had never encountered cancer patients who used ovarian cryopreservation, testicular tissue cryopreservation, in vitro fertilization with embryo cryopreservation and oocyte cryopreservation. The majority (78%) agreed that discussing fertility preservation with newly diagnosed cancer patients is a high priority. Conclusions: Oncologists in Oman are supportive of fertility preservation. The lack of knowledge and unavailability of well-structured fertility preservation services in Oman hinders the initiation of fertility preservation discussions.

Fertility preservation decisions in young women with breast cancer: a qualitative study of health care professionals' views and experiences

Fertility preservation (FP) discussions prior to breast cancer treatment are an important aspect of care and considered routine practice. However, studies show that women diagnosed with breast cancer have unmet needs about FP discussions. To better understand them, a qualitative study was conducted to explore the perceptions of healthcare professionals (HCPs) regarding FP for young women diagnosed with breast cancer. Semi-structured interviews were performed in a University teaching hospital to explore the knowledge, attitudes and reported behaviours of HCPs (oncologists, breast surgeons, breast care specialist nurses and fertility specialists) who offer FP discussions (n = 20). Data were analysed thematically. HCPs in this study were aware of the need to discuss FP with patients but were not confident in their knowledge and were unsure of their role in the discussion. Patient characteristics of younger age, nulliparity and ethnicity appeared to influence if and how HCPs discussed FP, in addition to the personal attitudes and knowledge of HCPs. Specialist nurses were identified as having an important role in FP discussions. Raising awareness of the essential components of FP discussions by a checklist or algorithm may help in addressing ambiguity and promoting consistent FP discussions by HCPs.

Psychological Aspects of Pregnancy and Lactation in Patients with Breast Cancer

Young breast cancer patients face numerous challenges during the cancer trajectory. As in the last decade, women tend to delay pregnancies to a later time in life, and clinicians are often faced with young breast cancer patients who want to start a family or complete it. Becoming a mother is a delicate developmental process in which the woman redefines and restructures her identity as she gets prepared for her new role and responsibilities. When there is a history of cancer or cancer diagnosis is communicated during the pregnancy, fears, worries, and concerns emerge and specific support may be necessary. Follow-ups during the post-partum period are also recommended as lactation issues should not be overlooked. In this chapter, we analyze the psychological aspects of cancer survivors and women with pregnancy-associated breast cancer, and the management of these issues.

[Desire for pregnancy and breast cancer]

Breast cancer affects about 3,000 new women of childbearing age each year. The desire for pregnancy is therefore a frequent issue in the management of breast cancer. We reviewed the current state of knowledge and recommendations in high-risk women, on the consideration of this desire for pregnancy in therapeutic management, the way to approach it, the preservation of fertility in the care process and finally on the outcomes of pregnancy after breast cancer. We evaluated the desire for pregnancy, qualitatively and quantitatively, after breast cancer through a literature review.

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.

Motherhood during or after breast cancer diagnosis: A qualitative study

OBJECTIVE

Little is known about the process of becoming a mother in women who experienced a breast cancer diagnosis (BC). In this qualitative study, we investigated maternal representations in pregnant women with experience of BC and those with no oncological history.

METHODS

A total of 38 women were recruited, 19 women who experienced a BC diagnosis and 19 who had not. To explore maternal representations, semi-structured interviews were conducted and analysed through thematic analysis.

RESULTS

Four main themes were identified: fears and worries, meaning of motherhood, mother-foetus relationship and partner support. Across themes, differences between primiparous and multiparous are reported. Women with gestational breast cancer (GBC) described fear for their own and their child's survival. Women with previous BC recall contrasting emotions. All women with experience of BC perceived breastfeeding as fundamental and inability to do so provoked worry. Relationship with the partner was considered central, while healthy women were projected towards the future triadic relationship.

CONCLUSIONS

Finding a mental space during pregnancy for the representation of the future child could be hard for women with GBC. Dissimilarities in the experience of motherhood in cancer patients provide insight into psychological aspects that should be taken into account in clinical practice.

Childbearing across borders: Fertility and parenthood attitudes and decisions among breast cancer survivors in USA and Portugal

OBJECTIVE

To compare fertility and childbearing attitudes and decisions of Portuguese and American female reproductive aged breast cancer survivors.

METHODS

This was a cross-sectional study of 102 young breast cancer survivors (59 from Portugal and 43 from USA). Demographic, clinical and reproductive information were collected. Fertility and parenthood attitudes and decisions were assessed through a self-report questionnaire devised specifically for the study.

RESULTS

Fertility issues became very important after the diagnosis for most of the women (51%). Few differences existed between USA and Portuguese participants. USA participants were more likely to undergo FP (23% USA vs Portugal 5%, p = 0.01). Portuguese women were more dissatisfied with their physician's explanations about fertility (Portugal: 23% vs USA: 3%; p = 0.01). Overall, women relied on their oncologist for fertility information (70%); only Portuguese women discussed fertility with their family medicine physician (11%). Overall, women showed positive attitudes towards motherhood. Portuguese women were more likely to report their partners placed more value on the family after their illness (Portuguese agree: 55% vs USA agree: 14%; p < 0.001).

CONCLUSIONS

Fertility and childbearing after breast cancer are important issues regardless of culture, background or country's heath care system. Overall, few differences across the USA and Portuguese samples were found on fertility and childbearing attitudes and decisions.

Patient-Physician Communication and Knowledge Regarding Fertility Issues from German Oncologists' Perspective-a Quantitative Survey

Many people diagnosed with haematologic malignancies are of child-bearing age. Typical treatment courses pose a high risk of infertility, and a lot of people affected by this are in the midst of starting or growing their families. Thus, it is crucial that they are well informed about fertility preservation options and can discuss these with an oncologist early on in the development of their treatment plans. Unfortunately, however, this does not always happen. One hundred twenty oncologists from 37 German adult clinical facilities were surveyed regarding their discussions with young patients about fertility, family planning, and fertility preservation. Almost all of them said that they consider fertility preservation to be an important issue. They also reported several factors as having an influence on the likelihood and practicability of discussing these subjects. Most knew about the existence of cryoconservation of germ cells and the use of GnRH analogues (95 %), but only half of them claimed to have a thorough understanding of these options. Many said they would like to learn more about this and that informational brochures could be helpful. Even though many oncologists do have good working knowledge of the subject, patients of reproductive age are not yet consistently given comprehensive information about the options available to them. To improve oncologists' knowledge of reproductive medicine, cooperation with fertility specialists should be facilitated, and informational leaflets should be made available both to patients and their medical care providers.

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.

Fertility outcome of breast cancer and Hodgkin's lymphoma female survivors: a growing clinical challenge for gynecologists and oncologists

The issue of taking into consideration future fertility in young women with breast cancer and Hodgkin's lymphoma [HL] will become more and more common and represent a growing clinical challenge for gynecologists and oncologists. The present paper will review literature data on the attempts of preventing chemotherapy-induced ovarian damage in these women and on their fertility outcome. Gonadotropin-releasing hormone [Gn-RH] agonists have been widely investigated as agents able to prevent ovarian failure in animal models and in humans. The majority of the studies on women with breast cancer and HL have shown a protective effect of Gn-RH agonists. A recent meta-analysis of five randomized trials, including 528 premenopausal breast cancer patients, revealed that relative risk [RR] of developing premature ovarian failure within one year was 0.40 (95% confidence interval [CI] = 0.21-0.75) for the women who received Gn-RH agonists with chemotherapy compared to those who received chemotherapy alone. However, the concurrent administration of Gn-RH agonists during chemotherapy appeared to have no effect on spontaneous pregnancy rates. Limited information are available about pregnancies in breast cancer and HL survivors, but the current literature appears to show no apparent increase in pregnancy complications, spontaneous abortions, or congenital abnormalities compared to general obstetric population.

Fertility preservation in cancer survivors: a national survey of oncologists' current knowledge, practice and attitudes

Background:

Around 1 in 10 of all cancer cases occur in adults of reproductive age. Cancer and its treatments can cause long-term effects, such as loss of fertility, which can lead to poor emotional adjustment. Unmet information needs are associated with higher levels of anxiety. US research suggests that many oncologists do not discuss fertility. Very little research exists about fertility information provision in the United Kingdom. This study aimed to explore current knowledge, practice and attitudes among oncologists in the United Kingdom regarding fertility preservation in patients of child-bearing age.

Methods:

A national online survey of 100 oncologists conducted online via medeconnect, a company which has exclusive access to the doctors.net.uk membership of GMC registered doctors.

Results:

Oncologists saw fertility preservation (FP) as mainly a women's issue, and yet only felt knowledgeable about sperm storage, not other methods of FP; 87% expressed a need for more information. Most reported discussing the impact of treatment on fertility with patients, but only 38% reported routinely providing patients with written information, and 1/3 reported they did not usually refer patients who had questions about fertility to a specialist fertility service. Twenty-three per cent had never consulted any FP guidelines. The main barriers to initiating discussions about FP were lack of time, lack of knowledge, perceived poor success rates of FP options, poor patient prognosis and, to a lesser extent, if the patient already had children, was single, or could not afford FP treatment.

Conclusion:

The findings from this study suggest a deficiency in UK oncologist's knowledge about FP options and highlights that the provision of information to patients about FP may be sub-optimal. Oncologists may benefit from further education, and further research is required to establish if patients perceive a need for further information about FP options.

Young breast cancer survivors: their perspectives on treatment decisions and fertility concerns

BACKGROUND

Younger women diagnosed with breast cancer are more likely to have survival concerns related to fertility, which may influence their treatment decisions.

OBJECTIVE

This qualitative study explores how young women make cancer treatment decisions and the role of fertility concerns in that process.

METHODS

We used purposeful sampling to identify a diverse group of 20 young breast cancer survivors, half of whom had a child after breast cancer. We conducted open-ended telephone interviews and used cross-case, inductive analysis to identify themes.

RESULTS

The main themes were (1) "I was young, I wanted to do everything possible to move forward with my life and not to have the cancer come back"; (2) "Fertility concerns are different for every woman"; (3) "My oncologist was great… a huge part of my survivorship"; and (4) "They didn't tell me about my options, and I didn't think about fertility until it was too late."

CONCLUSIONS

Although fertility was important to many participants, treatment decisions were mainly motivated by survival concerns. Fertility concerns depended on life circumstances, and the timing in relation to diagnosis varied. There is a need for improved information regarding the impact of treatment on fertility and fertility preservation options, even if concerns are not expressed at diagnosis.

IMPLICATIONS FOR PRACTICE

It is critical that cancer care providers provide timely information regarding fertility. Oncology nurses are particularly well positioned to serve this role by communicating with patients about their fertility concerns and reproductive planning prior to treatment and throughout the course of survivorship.

Barriers to procreational intentions among cancer survivors 2 years after diagnosis: a French national cross-sectional survey

OBJECTIVES

To determine the procreational intention rates among cancer survivors whose fertility was unimpaired and to identify the factors associated with their procreational intentions.

METHODS

Six thousand nine hundred and fifty-seven adult cancer patients treated between September and October 2002 were randomly selected from the French National Health Insurance Fund's Chronic Disease File. Of the 6957, 4270 responded to a cross-sectional questionnaire 2 years after diagnosis, of whom 959 reported being fertile and responded to a question about their procreational intentions.

RESULTS

Among the 257 male and female survivors aged 20-44, 86 (33.5%) had procreational intentions. After adjusting for age, gender, and already having children, only a high educational level (adjusted odds ratio: 3.1, 95% confidence interval 1.3-7.8) and stable or increasing financial resources (2.4, 1.0-5.7) were independently associated with the respondents' procreational intentions. Neither cancer stage at diagnosis nor the present stage significantly affected their plans in this respect.

CONCLUSIONS

Two years after cancer diagnosis, the reasons why some survivors who are still fertile have no parenthood projects were similar to those earlier given by members of the general population.

Physical and mental health correlates of pregnancy following breast cancer

INTRODUCTION

The safety of pregnancy after breast cancer is an important issue for many younger breast cancer survivors and their health care providers. Current research does not indicate that pregnancy negatively affects survival, but the 'healthy mother bias,' suggesting that survivors who go on to become pregnant are a self-selected healthier group based on their prognosis, has led to cautious interpretation of these findings. No studies have systematically evaluated the potential for this bias.

METHODS

This nested case-control study includes 81 younger participants from the Women's Healthy Eating and Living (WHEL) study (N=3088). Our sample includes 27 cases who had children after breast cancer and 54 controls, matched on age and stage at diagnosis. We used hierarchical linear modeling to accommodate longitudinal data with individuals nested within matched sets (cases and controls). The primary aim was to evaluate the association between summary scores of health and childbearing after breast cancer. Covariates were added for adjustment and to improve model precision.

RESULTS

Controlling for other variables in the model, physical health scores were not different between cases and controls (B=0.14, p=0.96). Mental health scores were marginally higher among cases (B=6.40, p=0.08), as compared with controls, a difference considered clinically significant.

CONCLUSION

This preliminary study did not find evidence of a healthy mother bias based on physical health. However, mental health was 6 points higher (p=0.08) among those who had children, indicating that the role of mental health needs evaluation in future research. Larger studies are needed to verify these findings.

Depressive symptoms among young breast cancer survivors: the importance of reproductive concerns

Breast cancer diagnosis and treatment can negatively impact fertility in premenopausal women and influence reproductive planning. This study investigates whether concerns about reproduction after breast cancer treatment were associated with long-term depressive symptoms. Participants include 131 women diagnosed with early-stage breast cancer at age 40 or younger participating in the Women's Healthy Eating and Living (WHEL) Survivorship Study. Participants were enrolled an average of 1.5 years postdiagnosis and depressive symptoms were monitored 6 times throughout the average additional 10 year follow-up period. Detailed recall of reproductive concerns after treatment was collected an average of 12 years postdiagnosis. Multilevel regression was used to evaluate whether mean long-term depressive symptoms differed as a function of reproductive concerns and significant covariates. Multilevel regression identified greater recalled reproductive concerns as an independent predictor of consistent depressive symptoms after controlling for both social support and physical health (B = 0.02, SE = 0.01, P = 0.04). In bivariate analyses, being nulliparous at diagnosis and reporting treatment-related ovarian damage were both strongly associated with higher reproductive concerns and with depressive symptoms. Reported reproductive concerns after breast cancer treatment were a significant contributor to consistent depressive symptoms. Younger survivors would benefit from additional information and support related to reproductive issues.

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.

Successful pregnancy after breast cancer therapy: dream or reality?

Background

Nowadays, more breast cancer patients want to have children after the diagnosis of cancer. The purpose of this study is to review the possibility and risks of giving birth among women with breast cancer previously treated by chemotherapy.

Case presentation

Two young women aged 28 and 34 respectively, were treated in our clinic for breast cancer, the first (negative hormonal receptors) by surgery, chemotherapy and radiotherapy and the second (positive hormonal receptors) by surgery, radiotherapy and tamoxifen. They both became pregnant, 1 and 8 years after completion of the therapy respectively.

Results

Laboratory testing during pregnancy was negative in both cases and after an uneventful course each woman gave birth to a perfectly healthy child. The first patient breastfed her baby for three months, while the second one did not breastfeed her baby at all.

Conclusion

Women undergoing chemotherapy for breast cancer can maintain their fertility and get pregnant. Previous chemotherapy for breast cancer does not present any supplementary risks for the child's mental or physical health.

Pregnancy after treatment of breast cancer--a population-based study on behalf of Danish Breast Cancer Cooperative Group

BACKGROUND

Estrogen is an established growth factor in breast cancer and it has been hypothesized that pregnancy associated estrogens may increase the risk of recurrence of breast cancer. In 1997 we published a population-based Danish study indicating no negative prognostic effect of pregnancy after breast cancer treatment. The present study is a ten-year update.

MATERIAL AND METHODS

Danish Breast Cancer Cooperative Group has since 1977 collected population-based data on tumour characteristics, treatment regimes, and follow-up status on Danish women with breast cancer. Pregnancy history was added from the Danish Civil Registration System, the National Birth Registry, and the National Induced Abortion registry. Cox regression was used to estimate the risk ratio of dying among women with a pregnancy after breast cancer treatment compared with women without such experience.

RESULTS

In all, 10 236 women with primary breast cancer aged 45 years or less at the time of diagnosis were followed for 95 616 person years. Among these, 371 women experienced pregnancy after treatment of breast cancer. In a multivariate analysis that included age at diagnosis, stage of disease, and pregnancy history prior to diagnosis, women who had a full-term pregnancy subsequent to breast cancer treatment were found to have a reduced risk of dying (relative risk: 0.73; 95% confidence interval: 0.54-0.99) compared with other women with breast cancer. The effect was not significantly modified by age at diagnosis, tumour size, nodal status, or pregnancy history before diagnosis of breast cancer. Neither spontaneous abortions nor induced abortions subsequent to breast cancer treatment had a negative impact on prognosis.

CONCLUSION

In line with our previous study, but based on more than twice the patient material, we found no evidence that a pregnancy after treatment of breast cancer has a negative influence the prognosis.

Ovarian function and childbearing issues in breast cancer survivors

The increasing number of breast cancer survivors makes the issues of ovarian dysfunction and childbearing ability more and more relevant for the quality of life of these patients. The incidence of ovarian dysfunction is related to patient age, the specific agents used and the total dose administered, especially the dose of alkylating agents such as cyclophosphamide. Amenorrhea rates following combination chemotherapy consisting of cyclophosphamide + methotrexate + 5-flurouracil (CMF regimen) range from 21 to 71% in women aged 40 years and younger, and from 40 to 100% in older ones. In most series anthracycline-based adjuvant chemotherapy regimens appear to have a lower incidence of amenorrhea, which is probably due to the lower cumulative cyclophosphamide dose administered compared with that given in the CMF regimen. Few data are currently available regarding ovarian function in women treated with taxane-based chemotherapy. In a recent retrospective study on 191 patients, the amenorrhea rate was 64% for women who received doxorubicin + cyclophosphamide (AC regimen) followed by a taxane, compared with 55% (p = 0.05) for those treated with AC alone. Forty percent of women aged 40 years or younger resumed menstruation, whereas the amenorrhea was more likely to be irreversible in older women; however, the addition of a taxane did not change the reversibility rate. Ovarian reserve can be tested with serum assays of follicle-stimulating hormone, inhibin B, estradiol and anti-Müllerian hormone, as well as by ultrasound assessment of antral follicle count. A review of literature data failed to show that a subsequent pregnancy increases the risk of recurrence and death in breast cancer survivors, and some series have even detected longer survival for patients who get pregnant after breast cancer treatment. This apparent survival benefit, probably due to a selection bias called the 'healthy mother effect', suggests that breast cancer survivors who subsequently conceive are a self-selecting group of women with better prognosis. The little available information appears to show no increase in the incidence of prematurity, stillbirth or congenital malformations in their babies. In conclusion, future pregnancy is a viable option for a woman treated for early-stage breast cancer and does not appear to be detrimental to either the mother or her offspring.

Current controversies in the management of early breast cancer

Medical professionals in general, and medical oncologists in particular, have highly stressful practices because they are under constant pressure to have the highest-quality, up-to-date evidence available in order to make the right decision for each individual patient. From a practical point of view, being updated on oncological and other medical specialties may seem an insurmountable task because the number of scientific publications has increased dramatically. The use of systematic reviews of randomised controlled trials or the application of results obtained from high-quality randomised controlled trials are some of the most common ways to address this need. Unfortunately, they do not cover all complex clinical situations that the majority of medical oncologists face in their outpatient consultations. In this review, we report the conclusions achieved in a multiexpert meeting where five important controversies in the treatment of breast cancer were analysed. Five highly experienced medical oncologists were required to defend an affirmative answer and another five were required to defend a negative answer for each of the clinical questions. After that, a one-day meeting was organised to debate each clinical question and to reach a consensus. We report here the content of this multi-expert meeting along with the conclusions drawn.
