The relationship between adiposity and breast cancer risk and prognosis is complex, with associations that differ depending on when body size is assessed (e.g., pre- vs. postmenopausal obesity) and when breast cancer is diagnosed (i.e., pre- vs. postmenopausal disease). Further, the impact of obesity on risk differs by tumor hormone receptor status (e.g., estrogen (ER) and progesterone (PR) receptor) and, among postmenopausal women, use of exogenous hormones (i.e., hormone replacement therapy (HRT)). In the context of these complexities, this review focuses on associations between childhood and adolescent adiposity, general adiposity, weight changes (i...

Survival rates have been excellent in patients treated for Hodgkin lymphoma (HL) during childhood and adolescence. Unfortunately, severe treatment related late effects have been observed. It was therefore an important aim of the cooperative pediatric HL therapy studies in Germany to reduce the number of late effects without jeopardizing the excellent treatment results. Progress and relapses of HL were analyzed to obtain important information for the future salvage therapy. All late effects were documented and their etiologies analyzed...

PURPOSE: Adolescents and young adults (AYAs) receiving cancer treatments that may impair fertility should receive counseling about risk of infertility and options for fertility preservation (FP) before treatment and/or during survivorship. Our objective was to define the AYA patient population referred to an on-site fertility consultation service within a comprehensive cancer center and determine factors associated with patients proceeding with FP treatment. METHODS: We conducted a retrospective chart review of AYA women who completed a consultation at the MD Anderson Fertility Preservation and Family Building Service during the first year of service...

BACKGROUND: While the breast cancer risk associated with increasing adult BMI in postmenopausal women can be explained by increases in concentrations of endogenous estrogens the biologic mechanisms behind the inverse association between adolescent BMI and breast cancer risk are still a subject of controversial debate. METHODS: We investigated the association of breast cancer with body size and changes in body size across life time estimated by age-specific BMI Z scores and changes in BMI Z scores from teenage years to middle age in an age-matched population-based case-control study of 2994 Australian women...

BACKGROUND: Gynecomastia is a common finding in male subjects which incidence varies widely in the world population. In adolescents, it is frequently temporary but, if it becomes persistent, it generates considerable embarrassment, inducing the patients to seek surgical consultation. Even in patients with good body contour, gynecomastia creates even greater distress considering the special attention given by these subjects to their physical appearance. The authors present their experience in the treatment of gynecomastia comparing different body types of patients with the aim to investigate dissimilar expectations, needs and surgical outcomes thus optimizing the management of the pathological condition, achieving high levels of agreement and reducing unsatisfied patients arising from cosmetic surgery...

BACKGROUND: Little is known about fish intake throughout the life course and the risk of breast cancer. METHODS: We used data on the first residence of 9,340 women born 1908-1935 in the Reykjavik Study as well as food frequency data for different periods of life from a subgroup of the cohort entering the AGES-Reykjavik Study (n = 2,882). RESULTS: During a mean follow-up of 27.3 years, 744 women were diagnosed with breast cancer in the Reykjavik Study...

Paroxetine, also known by the trade names Aropax, Paxil, Pexeva, Seroxat, Sereupin and Brisdelle, was first marketed in the U.S. in 1992. Effective for major depression and various anxiety disorders, it quickly gained a sizable share of the antidepressant prescription market. By the late 1990s, paroxetine frequently was being associated with serious drug interactions and medication side effects. Most significantly, in a major Canadian epidemiological study examining the relationship between antidepressants and diseases, paroxetine was associated with a 620 percent increase in the rate of breast cancer in women who had taken it over a four-year period...

The menarcheal age of Korean women has been rapidly decreasing for the last 50 years, and the average menarcheal age of women born in the 1990s is approaching 12.6 years. In addition, interest in early puberty has been increasing recently owing to the rapid increase in precocious puberty. Generally, out of concern for short stature and early menarche, idiopathic central precocious puberty in female adolescents is treated with gonadotropin-releasing hormone analogs. Studies to date have described the association between early menarche and psychosocial problems such as delinquency and risky sexual behavior, as well as physical health problems such as obesity, diabetes, cardiovascular diseases, and breast cancer throughout the lifespan of women...

Osteosarcomas are highly aggressive bone tumors that mainly occur in the metaphyses of long bones in children and adolescents. Genetically, they are characterized by complex structural and numerical aberrations with large intra- and interindividual variations which hamper the identification of the initiating and driving events. Sequencing and copy number analyses in a study of 123 pretherapeutic osteosarcoma samples identified mutations in 14 genes as the potential main drivers. Although almost half of all osteosarcomas could be attributed to mutations in TP53 and RB1, no single driver gene could be found that was clearly responsible for the majority of tumors...

BACKGROUND: Breast cancer is one of the most common cancers in female adolescent and young adults (AYA; age 15-39 years). However, few data exist detailing either in situ or invasive breast cancer in male AYAs. METHODS: All male AYA breast cancer cases were identified in the National Cancer Data Base (1998-2010). Demographics, tumor, and treatment predictors of overall survival (OS) were determined for both patients with in situ and invasive tumors. RESULTS: Of 677 male AYAs, 122 patients (18 %) had in situ breast cancer, while 555 patients (82 %) were found to have invasive breast cancer...

BACKGROUND: In animal models, long-term moderate energy restriction (ER) is reported to decelerate carcinogenesis, whereas the effect of severe ER is inconsistent. The impact of early-life ER on cancer risk has never been reviewed systematically and quantitatively based on observational studies in humans. OBJECTIVE: We conducted a systematic review of observational studies and a meta-(regression) analysis on cohort studies to clarify the association between early-life ER and organ site-specific cancer risk...

BACKGROUND: Menarche is a milestone for adolescent girls. The timing of menarche is influenced by genetics, social status and nutritional status (e.g., height, weight and body mass index [BMI]) and impacts future health (e.g., obesity and breast cancer). There have been many studies on trends in age at menarche among adolescent girls in China, but few have investigated associations between growth status and the timing of menarche. This study examined the association between age at menarche and growth status among adolescent girls in Western China...

The pattern of cancer seen in young people changes with increasing age, transitioning from childhood- to adult-type cancer in adolescence and the third decade. The risk factors, presentation and biology of cancer in young adults differ from those in the older adult population. Factors of particular significance in adolescents and young adults (AYAs) include genetic predisposition to adult-type cancer, diagnostic uncertainty, long-term morbidity and considerations of fertility. New systemic therapies are being introduced that can prolong life and even increase the chance of cure, but the impact on AYAs is uncertain, as these patients are often under-represented in clinical trials...

PURPOSE: To report the incidence of cancer in a cohort of adolescent idiopathic scoliosis (AIS) patients treated 25 years previously. METHODS: 215 consecutive AIS patients treated between 1983 and 1990 were identified and requested to return for clinical and radiographic examination. The incidence of cancer was determined through chart review and follow-up interviews. Using the original radiographic log file that included patient position, mAs, kV and the total number of X-rays taken, a radiation physicist calculated the total radiation dose during treatment and follow-up adjusted for BMI and sex...

Height and body size in childhood and young adulthood have been consistently associated with breast cancer risk; whether associations differ across molecular subtypes is unclear. In a pooled analysis of the Nurses' Health Studies, we prospectively examined the association of four exposures: height, body mass index (BMI) at the age of 18 years, childhood and adolescent somatotypes, with breast cancer risk according to molecular subtypes defined by immunohistochemical markers. We used multivariable-adjusted Cox proportional hazards regression to estimate HRs and 95% confidence intervals (CI)...

BACKGROUND: Breast cancer is rare in adolescents. In one study, breast carcinoma accounted for 0.02% of breast masses surgically removed in young women. We report a case of breast cancer in a 19-year-old woman who was found to have Li-Fraumeni Syndrome. CASE: The patient presented with a new, hard, nonmobile lump in the right breast which prompted her to seek medical attention. A biopsy identified invasive ductal carcinoma. Genetic testing showed a p53 mutation associated with Li-Fraumeni syndrome...

REVIEW
David N Danforth
Sporadic breast cancer develops through the accumulation of molecular abnormalities in normal breast tissue, resulting from exposure to estrogens and other carcinogens beginning at adolescence and continuing throughout life. These molecular changes may take a variety of forms, including numerical and structural chromosomal abnormalities, epigenetic changes, and gene expression alterations. To characterize these abnormalities, a review of the literature has been conducted to define the molecular changes in each of the above major genomic categories in normal breast tissue considered to be either at normal risk or at high risk for sporadic breast cancer...
