STUDY QUESTION: Is random start ovarian stimulation associated with delays in initiation of neoadjuvant chemotherapy for breast cancer? SUMMARY ANSWER: Among women who complete fertility preservation (FP) consultation, random start ovarian stimulation is unlikely to delay time to initiation of neoadjuvant chemotherapy start. WHAT IS KNOWN ALREADY: Neoadjuvant chemotherapy is now a widely accepted treatment modality for operable breast cancer and random start ovarian stimulation is an increasingly-utilized modality for FP...

PURPOSE: Reproductive-aged breast cancer survivors (BCS) who have completed initial cancer treatment frequently want to know about their future fertility potential. The purpose of this qualitative study was to assess if the fertility-related content presented in the survivorship care plan prototype met the informational needs of post-treatment BCS and to provide an opportunity for the target audience to review and react to the proposed content and design. METHODS: We conducted and analyzed transcripts from seven focus groups with BCS to evaluate their reactions to the survivorship care plan prototype...

Numerous treatments and protocols have been used to control the reproductive cycle in cattle, with varying effectiveness and many involving the administration of steroid hormones. Steroid hormones, such as estradiol, are perceived as having a negative impact on consumer health. This internationally shared opinion has led to a ban on the use of steroid hormones in food producing animals in many countries (i.e., European Union, New Zealand, and Australia). Letrozole, a non-steroidal aromatase inhibitor, inactivates the aromatase enzyme responsible for the synthesis of estrogens by reversibly binding to the "heme" group of the P450 subunit...

Mucin-4 (Muc4) is a large cell surface glycoprotein implicated in the protection and lubrication of epithelial structures. Previous studies suggest that aberrantly expressed Muc4 can influence the adhesiveness, proliferation, viability and invasiveness of cultured tumor cells, as well as the growth rate and metastatic efficiency of xenografted tumors. Although it has been suggested that one of the major mechanisms by which Muc4 potentiates tumor progression is via its engagement of the ErbB2/HER2 receptor tyrosine kinase, other mechanisms exist and remain to be delineated...

BACKGROUND: The numerous side effects of chemotherapy in patients with breast cancer are well known. However, the precise effects of chemotherapy on ovarian function in premenopausal women are poorly investigated. The patients are at risk of developing sexual hormone deficiency and impaired fertility. This prospective cohort study addresses predictive parameters of ovarian reserve after chemotherapy. METHODS: Fifty-one premenopausal women (28-46 years) with primary breast cancer were included in the trial...

BACKGROUND: Evidence indicates that breast cancer survivors with reproductive concerns have a poorer quality of life than survivors without fertility concerns. There is a lack of reliable and valid assessments of fertility intention among breast cancer survivors. PURPOSE: The aim of this study was to develop and validate the Fertility Intention Scale (FIS) that is sensitive to the fertility intention of women with breast cancer. METHODS: A literature review and a qualitative study were conducted to generate the items in the scale...

Because of the efficacy of systemic therapies, neoplasias which occur in pediatric and adolescent patients and in young adults have high cure rates. This means that fulfilling their wish to have children has become a more pressing concern, particularly among young women with malignant tumors. Premature ovarian failure is also a not insignificant problem as it has a lasting detrimental effect on quality of life. Every oncology patient who may potentially wish to have children should be informed about their options for preserving fertility prior to starting treatment...

Methylenetetrahydrofolate reductase (MTHFR) is a critical enzyme of folate pathway and required for DNA synthesis and methylation. MTHFE C677T polymorphisms is reported as risk factors for various diseases and disorders like birth defects, metabolic, neurological, psychiatric disorders, and cancers. Several studies have investigated association between the MTHFR C677T polymorphism and male infertility. To assess the risk associated with MTHFR C677T polymorphism in Asian population, a meta-analysis was performed...

STUDY QUESTION: Can supplementation of medium with prolactin (PRL), epidermal growth factor (EGF) and 4-hydroxyestradiol (4-OH-E2) prior to embryo transfer improve implantation potential in mouse blastocysts derived from IVF? SUMMARY ANSWER: Combined treatment with PRL, EGF and 4-OH-E2 improves mouse blastocyst implantation rates, while alone, each factor is ineffective. WHAT IS KNOWN ALREADY: Blastocyst dormancy during delayed implantation caused by ovariectomy is maintained by continued progesterone treatment in mice, and estrogen injection rapidly activates blastocysts to implantation-induced status in vivo...

Improvements in local and systemic treatment, along with earlier diagnoses through breast awareness and screening, have led to increases in survival and a decline in breast cancer (BC) recurrence. To the best of our knowledge, no meta-analysis has yet focused on pregnancy outcomes after BC treatment. Hence, our research group explored the reproductive outcomes (pregnancy, miscarriage, termination of pregnancy, live births) after BC treatment. The Embase, MEDLINE, PubMed, and Scopus databases were searched. Studies were included that reported on pregnancy and reproductive outcomes after treatment of BC...

Despite the high rates of breast cancer among young Mexican women, their special needs and concerns have not been systematically addressed. To fulfill these unsatisfied demands, we have developed "Joven & Fuerte: Program for Young Women with Breast Cancer in Mexico," the first program dedicated to the care of young breast cancer patients in Latin America, which is taking place at the National Cancer Institute of Mexico and the two medical facilities of the Instituto Tecnológico y de Estudios Superiores de Monterrey...

Young women with breast cancer have age-specific concerns regarding changes in sexuality, fertility, and body image. However, the psychological impact of BC and its treatments is not exclusive to young patients and it also affects their social context, especially their partners, as they experience higher illness intrusiveness than the partners of older women. In young BC patients, relationships, body image, and sexual problems are related to most quality of life domains. While BC treatment is being planned, all women should be informed about the possible side-effects of treatment on sexuality, fertility, and body image...

Fertility and pregnancy-related issues represent one of the main areas of concerns for young women with breast cancer. Carrying a germline deleterious BRCA mutation adds additional burden on this regard due to the specific issues that should be considered during the oncofertility counseling of this special patient group. Despite the availability of a growing amount of data in the general breast cancer population on the feasibility and safety of fertility preservation and pregnancy after diagnosis, numerous challenges remain for BRCA-mutated breast cancer patients in whom very limited studies have been performed so far...

Triple-negative breast cancers (TNBCs) have poor prognosis, and chemotherapy remains the mainstay of therapy because of lack of discovered possible target. MYC were found overexpressed in TNBCs compared with other subtypes and especially in those resistant to chemotherapy, but the inhibition has been challenging to achieve. Recently, the cooperation of PIM1 and MYC was identified involved in cell proliferation, migration and apoptosis of TNBCs, which has been reported in hematological malignancy and prostatic cancer...

BACKGROUND: Chemotherapy for breast cancer may have a negative impact on reproductive function due to gonadotoxicity. Fertility preservation via banking of oocytes or embryos after ovarian stimulation with FSH can increase the likelihood of a future live birth. It has been hypothesized that elevated serum estrogen levels during ovarian stimulation may induce breast tumour growth. This has led to the use of alternative stimulation protocols with addition of tamoxifen or letrozole. The effectiveness of these stimulation protocols in terms of oocyte yield is unknown...

INTRODUCTION: In the last decades, long-term outcomes of young women with breast cancer have greatly improved, raising several new survivorship needs which include fertility preservation and pregnancy. The prejudice against pregnancy after breast cancer is still alive among different healthcare providers (e.g. gynecologists, oncologists, general practitioners) and women are often confused and left alone in their family decision planning. EVIDENCE ACQUISITION AND SYNTHESIS: All the available retrospective data confirm pregnancy after breast cancer is safe both for the mother and the offspring, also in women with hormone receptor positive disease...
