Cancer breast pregnancy

Ashley S Case
Breast cancer is one of the most common malignancies affecting pregnancy. Pregnancy-associated breast cancer refers to breast cancer that is diagnosed during pregnancy or within the first postpartum year. The incidence is increasing as more women delay childbearing. Breast cancer can be safely diagnosed, staged, and treated during pregnancy while protecting the fetus and mother with excellent outcomes for both. Avoiding diagnostic delays is vital to prognosis. This article provides an overview of the diagnosis, staging, management, and prognosis of pregnancy-associated breast cancer...

BACKGROUND: Internal medicine residents are expected to be able to provide gender-specific care. The objective of this study was to develop a consensus list of core topics and procedural skills in women's health to allow residency program directors to prioritize and standardize educational efforts in women's health. METHODS: We conducted a two-round Delphi of women's health experts. Participants were given a list of topics and asked to: (1) rank each topic based on how important they felt each topic was for internal medicine residents to be proficient in upon graduation, and (2) identify which topics were critical for a women's health curriculum...

BACKGROUND: Type 2 diabetes is associated with breast cancer in epidemiologic studies. Pregnancy also modifies breast cancer risk. We hypothesized that women with a history of gestational diabetes mellitus (GDM), which shares pathogenesis and risk factors with type 2 diabetes, would have greater invasive breast cancer risk than parous women without a history of GDM. METHODS: We conducted a prospective analysis among parous women in the Nurses' Health Study II, with mean age 35 years in 1989...

BACKGROUND: Breast density, the amount of fibroglandular tissue in the adult breast for a women's age and body mass index, is a strong biomarker of susceptibility to breast cancer, which may, like breast cancer risk itself, be influenced by events early in life. In the present study, we investigated the association between pre-natal exposures and breast tissue composition. METHODS: A sample of 500 young, nulliparous women (aged approximately 21 years) from a U...

RAD51, RAD52, and XRCC2 are all involved in DNA homologous recombinational repair, and there are interactions among those genes. Polymorphisms in 3'-UTR of DNA repair genes may change DNA repair capacity by regulating gene expression. However, potential regulatory variants affecting their expression remain largely unexplored. Five miRNA-binding site SNPs (rs7180135 and rs45549040 in RAD51, rs1051669 and rs7963551 in RAD52 and rs3218550 in XRCC2) selected by bioinformatics method were genotyped in 498 breast cancer (BC) patients and 498 matched controls in Chinese population...

BACKGROUND: Malignant phyllodes tumors of the breast are rare biphasic neoplasms. Only few cases related to pregnancy have been reported. CASE REPORT: A 37-year-old woman presented with swelling and pain in her left breast as well as hyperemia on the breast skin, 4 weeks after labor. In her family history, her aunt and maternal cousin had had a breast cancer diagnosis. Clinical evaluation of the patient was consistent with a breast abscess. Therefore, abscess drainage and biopsy from the cavity wall were performed...

Mammary gland regression at the cessation of lactation (involution) is an exquisitely orchestrated process of cell death and tissue remodelling in which Stat3 signalling has an essential role. The involution microenvironment of the mammary gland is considered to be pro-tumourigenic and a proportion of cases of pregnancy-associated breast cancer are suggested to originate in tandem with involution. However, the apparent paradox that STAT3 is required for cell death in normal mammary gland, but is associated with breast cancer cell survival, has not been resolved...

BACKGROUND: Finding a tumor marker to predict the aggressive behavior of molar pregnancy in early stages has yet been a topic for studies. OBJECTIVES: In this survey we planned to study patients with molar pregnancy to 1) assess the p53 and c-erbB-2 expression in trophoblastic tissue, 2) to study the relationship between their expression intensity and progression of a molar pregnancy to gestational trophoblastic neoplasia, and 3) to determine a cut off value for the amount of p53 and c-erbB-2 expression which might correlate with aggressive behavior of molar pregnancy...

OBJECTIVE: Previous meta-analyses have examined the prognosis of women with pregnancy-associated breast cancer (PABC) as well as pregnancy that follows breast cancer diagnosis. Since then, many additional studies have been performed. We conducted an updated meta-analysis to examine the prognosis for women who become pregnant before, during and after a diagnosis of breast cancer. We also performed analyses on the various subgroups within PABC such as pregnancy and postpartum cases, as well as on time periods postpartum...

The coexistence of malignant tumour and pregnancy is a state of simultaneous occurrence of two completely contradictory philosophical and biological phenomena - the development of a new life and a life-threatening terminal illness. Finally, a physician - in fact the whole team of doctors - is facing the fight for two lives: of the mother and her unborn child. The incidence of malignant disease in pregnancy is 0.05 to 0.1%. This condition is a major challenge for physicians because there are no randomised studies that could be the basis to choose the therapeutic methods - the medical knowledge merely comes from case reports, registries, and observational studies...

Nausea and vomiting are among the most serious side effects of chemotherapy, in some cases leading to treatment interruption or chemotherapy dose reduction. Ginger has long been known as an antiemetic drug, used for conditions such as motion sickness, nausea-vomiting in pregnancy, and post-operation side effects. One hundred and fifty female patients with breast cancer entered this prospective study and were randomized to receive ginger (500 mg ginger powder, twice a day for 3 days) or placebo. One hundred and nineteen patients completed the study: 57 of them received ginger and 62 received ginger for the frst 3 chemotherapy cycles...

Recent data from The Cancer Genome Atlas analysis have revealed that Aurora kinase A (AURKA) amplification and overexpression characterize a distinct subset of human tumors across multiple cancer types. Although elevated expression of AURKA has been shown to induce oncogenic phenotypes in cells in vitro, findings from transgenic mouse models of Aurora-A overexpression in mammary glands have been distinct depending on the models generated. In the present study, we report that prolonged overexpression of AURKA transgene in mammary epithelium driven by ovine β-lactoglobulin promoter, activated through multiple pregnancy and lactation cycles, results in the development of mammary adenocarcinomas with alterations in cancer-relevant genes and epithelial-to-mesenchymal transition...

This study estimated the fetal dose and risks from radiotherapy for breast cancer with 6 MV X-rays. Breast irradiation was simulated with the MCNP code using two mathematical phantoms corresponding to patients in the early and middle periods of pregnancy. Monte Carlo simulations were performed to determine the appropriate fetal shielding. For a 50-Gy tumor dose, the unshielded fetal dose reached up to 133.1 mGy. Fetal protection with a lead shield of dimensions 30 × 30 × 5 cm(3) placed besides the treatment couch resulted in maximum doses of 22...

The development of a recommendation was intended for the follow-up of breast cancer patients treated with curative intent in Hungary. Follow-up includes the permanent contact with and health education of the patient, the surveillance and control of the adverse effects of oncological therapies or radiotherapy, the screening of metachron cancers, and the comprehensive (physical, psychological and social) rehabilitation of the patient. The early detection of local/regional tumor relapse is essential with careful follow-up, but there is no need for screening of distant metastases by means of imaging studies or tumor marker tests...

Despite the introduction of promising products into the contraceptive market, the rate of unintended pregnancies remains high. Women with underlying medical conditions should have access to safe and effective contraceptive methods for various reasons, including the potential deleterious effect of the disease on the pregnancy or the effect of the pregnancy on the disease process. Healthcare providers are often confronted with cases in which contraception counseling is problematic due to controversial evidence and persistent myths...

A previously healthy, 30-year-old Filipino woman presented to an emergency department with complaints of shortness of breath and mild cough. She denied constitutional symptoms, such as night sweats, fevers, loss of appetite, or weight loss. Additional investigation revealed bilateral pleural and pericardial effusions with no obvious lung lesions or masses. The pericardial fluid was drained and preliminary cytology revealed atypical carcinoma cells. Her past medical history included an embryonic pregnancy and a benign breast cyst that was biopsied in the Philippines...

The hormonal milieu of an early full-term pregnancy induces lobular development, completing the cycle of differentiation of the breast. This process induces a specific genomic signature in the mammary gland that is represented by the stem cell containing a heterochomatin condensed nucleus (HTN). Even though differentiation significantly reduces cell proliferation in the mammary gland, the mammary epithelium remains capable of responding with proliferation to given stimuli, such as a new pregnancy. The stem cell HTN is able to metabolize the carcinogen and repair the induced DNA damage more efficiently than the stem cell containing an euchromatinic structure (EUN), as it has been demonstrated in the rodent experimental system...

There is limited evidence that the gestational age at delivery may influence the risk of maternal breast cancer. While extreme prematurity has been suggested to increase the risk, there seems to be no study available so far that investigates the due effects of a late delivery. This research aimed to identify the impact of both preterm and late deliveries on the risk of maternal breast cancer within a period of 5 years after birth. Our dataset was created by linking data from the Nevada Cancer Registry database (1995-2008) and the birth certificates issued by the Nevada State Health Division (1994-2003)...
