There is evidence of poor prognosis in women with pregnancy-associated breast cancer (PABC) diagnosed during pregnancy or within two years of delivery. Using a large, population-based cohort, we examined clinicopathologic features and survival in women with PABC. A cohort of women diagnosed with invasive breast cancer between 1992 and 2009 at ages 15 to 44 years was identified in the Swedish Cancer Register and the Breast Cancer Quality Registers. Dates of childbirths for each woman were retrieved from the Swedish Multi-Generation Register...

BACKGROUND: Cancer treatment during pregnancy is a growing problem especially now that women delay childbearing. Systemic treatment of these malignancies during pregnancy centers mainly on the anticancer drugs anthracyclines, widely used in treating hematological and breast cancer during pregnancy and sometimes associated with early and late toxicity for the fetus. Owing to concern about their cardiac and neurodevelopmental toxicity more information is needed on which anthracycline to prefer and whether they can safely guarantee a cardiotoxicity-free outcome in the fetus...

Ischaemic stroke is rare in premenopausal women but risk increases with advancing age and doubles in the ten years following the menopause. Up to the age of 75 years men have a 25% higher risk of suffering a stroke compared with women. However, the increased life expectancy of women ultimately results in a higher overall incidence. Twice as many women die from stroke compare with breast cancer. Women with cerebrovascular disease are more likely to present with atypical symptoms than men. Altered mental status (including unresponsiveness, confusion and behavioural change) is the most common nonconventional symptom, and is reported by 23% of women compared with 15% of men...

BACKGROUND: Previous studies have shown that reproductive factors are differentially associated with breast cancer (BC) risk by subtypes. The aim of this study was to investigate associations between reproductive factors and BC subtypes, and whether these vary by age at diagnosis. METHODS: We used pooled data on tumor markers (estrogen and progesterone receptor, human epidermal growth factor receptor-2 (HER2)) and reproductive risk factors (parity, age at first full-time pregnancy (FFTP) and age at menarche) from 28,095 patients with invasive BC from 34 studies participating in the Breast Cancer Association Consortium (BCAC)...

INTRODUCTION: We sought to characterize changes in healthcare spending associated with the onset of 22 endometriosis-related comorbidities. METHODS: Women aged 18-49 years with endometriosis (N = 180,278) were extracted from 2006-2015 de-identified Clinformatics(®) DataMart claims data. For 22 comorbidities, comorbidity patients were identified on the basis of having a first comorbidity diagnosis after their initial endometriosis diagnosis. Controls were identified on the basis of having no comorbidity diagnosis and were matched 1:1 to comorbidity patients on demographics and baseline spending...

Marilita M Moschos, Eirini Nitoda
The aim of this manuscript is to review the action and adverse effects of combined oral contraceptives (COCs) on ocular tissues. The percentage of unwanted pregnancies and the subsequent abortions make contraception crucial worldwide. Over 100 million women around the world use common contraceptive methods, including intrauterine devices, combined estrogen and progestin oral contraceptives, as well as progestin only preparations (oral contraceptives, implants or injections). COCs are widely used for contraception, but they are also indicated in menorrhagia, endometriosis, acne and hirsutism, fibroid uterus and premenstrual syndrome...

Pregnancy-associated breast cancer is defined as invasive breast cancer diagnosed during gestation, within 1 year postpartum, or during lactation. Of particular interest is the treatment of invasive breast cancer during gestation; standard treatment protocols must take into account the health of the fetus. This article reviews the literature and emerging data regarding the treatment of pregnancy-associated breast cancer. Existing staging and treatment practices need slight modification in the setting of pregnancy...

Context: Full-term pregnancy is associated with a transient increase and life-time decrease in maternal breast cancer risk. Estrone (E1), estradiol (E2), and estriol (E3) are in high concentration during the third trimester. E1 and E2 metabolism produces carcinogenic intermediaries, and E3 metabolism does not. Objective: We tested the hypothesis that higher E3 in pregnancy is protective while higher E1 plus E2 increases risk. Design: Prospective case-cohort study (n = 620; 204 cases) nested in a 38-year follow-up of 15,528 pregnant women in the Child Health and Development Studies...

PURPOSE: Germline mutations in the BRCA1 and BRCA2 genes confer increased risks for breast cancers. However, the clinical presentation of breast cancer among women who are carriers of the BRCA1 or BRCA2 (BRCA1/2 carriers) mutations is heterogenous. We aimed to identify the effects of the reproductive histories of women with the BRCA1/2 mutations on the clinical presentation of breast cancer. METHODS: We retrospectively analyzed clinical data on women with proven BRCA1 and BRCA2 mutations who were recruited to the Korean Hereditary Breast Cancer study, from 2007 to 2014...

PURPOSE: Consumption of alcoholic beverages during adolescence and early adulthood has been consistently associated with higher breast cancer risk. The influence of alcohol consumption early in life on mammographic breast density, a marker of breast cancer risk, is inconclusive. This study examined associations of alcohol consumption across the life course with premenopausal mammographic density. METHODS: The study population included 1211 premenopausal women in the Nurses' Health Study II without cancer, who recalled their alcohol consumption at age 15 through enrollment in 1989 (baseline), and had mammograms available...

REVIEW
Michalis Mazonakis, John Damilakis
The appearance of a malignant disease during pregnancy is relatively rare. The use of external-beam radiation therapy is limited to non-pelvic tumors which are usually located above the diaphragm. However, supradiaphragmatic radiotherapy unavoidably exposes the fetus to secondary radiation due to head leakage, scatter from the machine and scatter produced inside the patient. This fetal exposure may be associated with an elevated risk for the development of deterministic harmful effects and/or carcinogenesis...
