Introduction : Phylloides tumours (PTs) are rare fibroepithelial neoplasms that account for 0.3⁻0.9% of all breast tumours. These tumours typically occur in women aged 30⁻70 years. The occurrence of these tumours in older children and adolescents poses particular diagnostic and therapeutic problems. However, early diagnosis is mandatory because although most of the cases of PTs in children are benign, the borderline and malignant cases with potential negative outcomes cannot be excluded. Case presentation : A 12-year-old girl presented at the Paediatric Emergency Department for hyperaemia and warmth of the left breast that occurred a few days prior without fever...

BACKGROUND: Many studies have examined long-term outcomes after childhood cancer, but few address outcomes for adolescent and young adult (AYA; those aged 15-39 years) cancer survivors. Conditional survival reflects changing mortality risk with time since cancer diagnosis and is a useful measure for planning long-term follow-up care. METHODS: Using the Surveillance, Epidemiology, and End Results registry 9 database, the authors identified a cohort of AYA patients diagnosed with a first malignant cancer between 1973 and 2009 and followed through 2014...

Breast cancer (BC) is the most frequent malignancy in both pre- and postmenopausal women. However, it is exceedingly rare in very young patients, and especially in adolescents. Herein, we report a case of an 18-year-old female diagnosed with invasive BC. The proband had been found to be negative for BC in close family members. A common BC genetic screening test for the Polish population did not detect any known founder mutations in the BRCA1 gene. Further evaluation identified a p.Ile157Thr (I157T) mutation in the CHEK2 gene, a p...

Background: Carcinogenic exposure in early life may be critical for subsequent breast cancer risk. Dairy consumption was examined during adolescence and early adulthood in relation to incident breast cancer in the Nurses' Health Study II cohort. Methods: For the analyses of early adulthood dairy consumption, we included 90,503 premenopausal women ages 27 to 44 years in 1991 who reported dairy consumption using a validated food-frequency questionnaire. From 1991 to 2013, 3,191 invasive breast cancer cases were identified...

BACKGROUND: The age of menarche has been associated with metabolic and cardiovascular disease, as well as cancer risk. The decline in menarcheal age over the past century may be partially attributable to increased exposure to endocrine disrupting chemicals (EDCs). METHODS: We assessed the influence of 26 phenol and phthalate biomarkers on the timing of menarche in a longitudinal cohort of Chilean girls. These EDCs were quantified in urine collected prior to the onset of breast development (Tanner 1; B1), and during adolescence (Tanner 4; B4)...

INTRODUCTION: Adolescents and young adults (AYAs) diagnosed with cancer between ages 15-39 years may harbour germline variants associated with cancer predisposition. Such variants represent putative therapeutic targets, as may somatic variants in the tumour. Germline and tumour molecular profiling is increasingly utilised to facilitate personalisation of cancer treatment in such individuals. AIM: Considering AYAs with advanced solid tumours managed in a specialist drug development unit (DDU), the aims of this study were to investigate the use and impact of: 1...

OBJECTIVE: The negative impact of malignant disease on sexual and relational functioning is well-documented among adults, but scarcely investigated among adolescents and young adults. This study explored the body image, self-perceived attractiveness and sexual/romantic experiences of Danes diagnosed with cancer at the age of 15-29 years. It also aimed to clarify whether self-perceived needs for counseling were in fact met by health-care providers. METHODS: All Danes who had been diagnosed with cancer at the age of 15-29 years during the period 2009-2013 were included in a cross-sectional nationwide questionnaire study...

There has been little improvement in the prognosis for adolescent and young adult (AYA) tumor patients. Hence, there is an urgent need to understand the etiology of tumor development and identify actionable gene aberrations to improve prevention and therapy. Here, 76 sporadic tumors (48 breast, 22 ovarian, and six uterine) from 76 AYA females (age range, 25-39 years) were subjected to whole exome and RNA sequencing to determine their mutational signatures and actionable gene profiles. Two individuals with breast cancer (4...

BACKGROUND: Physical activity is inversely associated with the risk of breast cancer among women in the general population. It is not clear whether or not physical activity is associated with the risk of BRCA-associated breast cancer. METHODS: We conducted a case-control study of 443 matched pairs of BRCA mutation carriers to evaluate the association between physical activity and breast cancer risk. Moderate and vigorous physical activities at ages 12-13, ages 14-17, ages 18-22, ages 23-29 and ages 30-34 were determined using the Nurses' Health Study II Physical Activity Questionnaire...

BACKGROUND: Although it has been well-documented that obesity is associated with decreased risk of premenopausal breast cancer and increased risk of postmenopausal breast cancer, it is unclear whether these associations differ among breast cancer subtypes defined by the tumor protein expression status of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). METHODS: We evaluated the associations of body mass index (BMI) at age 18 years and recent BMI in relation to risk of breast cancer overall and ER/PR/HER2-defined subtypes, in 6320 women (3934 case-patient participants, 2386 control participants) aged 35-64 years, who participated in one of three population-based case-control studies...

INTRODUCTION: The American College of Radiology's Breast Imaging Reporting and Data System (BI-RADS) was developed to guide imaging-based surgical treatment in patients with breast cancer. Studies confirming the BI-RADS did not include adolescents. To evaluate the validity of this classification system in adolescents, we aim to investigate the relationship between the BI-RADS and pathology findings in adolescents. METHODS: The medical data of 67 female adolescent patients, aged 12 to 18, referred to our clinic for breast-related complaints between 2013 and 2016 were reviewed retrospectively for demographic data and the results of radiologic and surgical pathologies...

AIMS: New Zealand currently defines the adolescent and young adult (AYA) group for cancer services as young people 12-24 years of age, while other countries favour a designation of 15-29 years. This study was undertaken to compare cancer incidence and survival among 25-29 year olds to New Zealand's younger AYA population and to assess survival for our 15-29 year population against international benchmarks. METHODS: Diagnostic and demographic information for cancer registrations between 2000 and 2009 for 25-29 year olds was obtained from the New Zealand Cancer Registry...

PURPOSE: Multiple studies have examined the role of anthropometric characteristics in ovarian cancer risk and survival; however, their results have been conflicting. We investigated the associations between weight change, height and height change and risk and outcome of ovarian cancer using data from a large population-based case-control study. METHODS: Data from 699 ovarian cancer cases and 1,802 controls who participated in the HOPE study were included. We used unconditional logistic regression adjusted for age, race, number of pregnancies, use of oral contraceptives, and family history of breast or ovarian cancer to examine the associations between self-reported height and weight and height change with ovarian cancer risk...

Epigenetic age is an indicator of biological aging, capturing the impact of environmental and behavioral influences across time on cellular function. Deviance between epigenetic age and chronological age (AgeAccel) is a predictor of health. Pubertal timing has similarly been associated with cancer risk and mortality rate among females. We examined the association between AgeAccel and pubertal timing and adolescent breast composition in the longitudinal Growth and Obesity Cohort Study. AgeAccel was estimated in whole blood using the Horvath method at breast Tanner 2 (B2) and 4 (B4)...
