In prostate cancer, reliable information about the lymph node status is of great importance for accurate staging and the optimal planning of treatment. Despite recent advances in imaging, the histological detection of metastases, or pelvic lymphadenectomy (PLND), continues to be the most reliable method for lymph node staging in clinically localised prostate cancer, especially as this procedure enables the detection of small or micrometastases. Radioisotope-guided sentinel PLND (sPLND) demonstrates high sensitivity in the detection of lymph node metastases as well as low morbidity in prostate cancer because of the targeted removal of a relatively small number of lymph nodes...

BACKGROUND: Although some studies suggest that breast-conserving therapy (BCT) shows better psychosocial outcomes than mastectomy in patients with primary breast cancer, little is known about the outcomes of these surgical options in recurrent breast cancer. We investigated differences in overall survival and re-recurrence rates as well as psychosocial outcomes among patients who underwent BCT or mastectomy after the diagnosis of recurrent breast cancer in a single-center setting. METHODS: 124 of 186 eligible patients who underwent surgical treatment for breast cancer recurrence completed the questionnaires on quality of life (EORTC QLQ-C30 and -BR23), fear of progression (PA-F-KF), anxiety and depression (HADS), and body image (BIS)...

CONTEXT: Most estrogen-dependent breast cancers occur after menopause despite low levels of circulating estrogens. Breast expression of the estrogen-biosynthetic enzyme, aromatase, is proposed to drive breast cancer development after menopause. However, the effects of menopause on breast aromatase expression are unknown. OBJECTIVE: To determine the effect of menopause on breast aromatase expression in relation to body mass index (BMI), white adipose tissue inflammation (WATi) and systemic markers of metabolic dysfunction...

Yu-Wei Chang, Kamaleshwar P Singh
Chemotherapy is the most common clinical option for treatment of breast cancer. However, the efficacy of chemotherapy depends on the age of breast cancer patients. Breast tissues are estrogen responsive and the levels of ovarian estrogen vary among the breast cancer patients primarily between pre- and post-menopausal age. Whether this age-dependent variation in estrogen levels influences the chemotherapeutic efficacy in breast cancer patients is not known. Therefore, the objective of this study was to evaluate the effects of natural estrogen 17 beta-estradiol (E2) on the efficacy of chemotherapeutic drugs in breast cancer cells...

PURPOSE: Studies have suggested a potential role of patient's co-morbidity in determining the survival outcomes of breast cancer. In this study, we examined the long-term oncologic outcomes in breast cancer patients who underwent curative surgery according to their pre-existing comorbid conditions and analyzed the association between the co-morbidity and the use of adjuvant therapies. METHODS: The medical records of 2,501 patients who underwent surgery for primary breast cancer from June 2006 to June 2010 were reviewed retrospectively...

BACKGROUND: Breast cancer treatment-related lymphedema (BCRL) arises from a mechanical insufficiency following cancer therapies. Early BCRL detection and personalized intervention require an improved understanding of the physiological processes that initiate lymphatic impairment. Here, internal magnetic resonance imaging (MRI) measures of the tissue microenvironment were paired with clinical measures of tissue structure to test fundamental hypotheses regarding structural tissue and muscle changes after the commonly used therapeutic intervention of manual lymphatic drainage (MLD)...

This phenomenological study examined the experiences of men who committed to romantic relationships with women under 50, post breast cancer diagnosis and treatment. Twelve men from throughout the United States, who were dating their partner for at least six months, participated in semi-structured interviews. Findings focused on initial disclosure timing, previous experience/knowledge about the cancer, reacting with acceptance despite concerns, focusing on love/connection, respecting and admiring the survivor, and the ongoing impact of cancer on the relationship...

"Nudge, or nudging, refers to a policy approach inspired by behavioral sciences: it promotes the conducts identified as desirable by regulators without applying prohibition and coercion. This approach has gained a lot of momentum in the domain of health policies. Policy strategies based on behavioral insights appear ideal as to implementing healthier life styles and public health programs while minimizing compliance costs: from organ donation to food choices, from fighting obesity and chronic diseases to screening policies...

Despite ongoing efforts to improve rural healthcare, the health problems facing rural communities persist. The lack of healthcare providers and infrastructure in rural areas has been linked to a number of negative consequences. Among the elderly rural population, the lack of proximal access presents greater barriers because many elderly people are further limited in their ability to travel and pay for services. In the Deep South specifically, rural residents experience limited access to care and overall poor health outcomes...

PURPOSE: The aim of this study was to explore the treatment, patient, and impairment-related risk factors associated with upper limb dysfunctions in breast cancer survivors. METHODS: A cross-sectional study was performed in 274 women treated for breast cancer. The following risk factors were analysed by bivariable and multivariable analysis: 1) treatment-related variables (type of surgery, levels of lymph node dissected, radiotherapy, chemotherapy, hormone therapy and trastuzumab); 2) patient's related variables (age and Body Mass Index); 3) and finally impairment-related variables such as pain (intensity, quality and pressure hypersensitivity, signs of central sensitisation, the degree of pain catastrophizing and vigilance and awareness to pain), active ROM and upper limb strength were investigated...

BACKGROUND: There is accumulating epidemiological and preclinical evidence that estrogen might be a driver of lung cancer. Breast cancer survivors can offer a unique patient cohort to examine the effect of antiestrogen therapy on lung cancer carcinogenesis because many of these women would have received long-term selective estrogen receptor modulators (SERMs) and/or aromatase inhibitors (AIs) as adjuvant treatment. Our hypothesis is that estrogens play a role in lung cancer development, and that antiestrogen therapy would affect the incidence of subsequent lung cancer among breast cancer survivors...

Clinical trial duration may be a concern in clinical research, especially in cancer trials where the endpoint is overall survival. A surrogate endpoint can be used as an auxiliary variable to analyze the treatment effect earlier. At an early time point, the high number of censored observations can be compensated by the imputation of the unobserved deaths times. We propose to use predictions of the risk of death from a joint model for a recurrent event and a terminal event, which account for disease relapse information...

Importance: Primary care clinicians, who are increasingly responsible for caring for the growing population of cancer survivors, may be unfamiliar with appropriate cancer surveillance strategies. Clinical practice guidelines can inform cancer follow-up care and surveillance testing. Vague recommendations and inconsistencies among guidelines can lead to overuse and underuse of health care resources and have a negative impact on cost and quality of survivorship care. Objective: To examine the specificity and consistency of recommendations for surveillance after active treatment across cancer guidelines...

Antiestrogen-resistant and triple-negative breast tumors pose a serious clinical challenge because of limited treatment options. We assessed global gene expression changes in antiestrogen-sensitive compared with antiestrogen-resistant (two tamoxifen resistant and two fulvestrant resistant) MCF-7 breast cancer cell lines. The branched-chain amino acid transaminase 1 (BCAT1), which catalyzes the first step in the breakdown of branched-chain amino acids, was among the most upregulated transcripts in antiestrogen-resistant cells...

We present an updated account of breast cancer treatment and of progress toward "precision" cancer therapy; we focus on new developments in diagnostic molecular pathology and breast cancer that have emerged during the past 2 years. Increasing awareness of new prognostic and predictive methodologies, and introduction of next generation sequencing has increased understanding of both tumor biology and clinical behavior, which offers the possibility of more appropriate therapeutic choices. It remains unclear which of these testing methodologies provides the most informative and cost-effective actionable results for predictive and prognostic pathology...
