The incidence of malignant melanoma worldwide continues to grow despite the enormous advances in topical and systemic therapy. This increase is recorded regularly even in countries where, as a result of public health campaigns, dermatological examination and subsequent treatment have become more frequent. However, there have been reports of a stable or even decreasing mortality rate that seem to contradict the objective increase in its incidence. The well-known risk factors for malignant melanoma include sunburns and occasional sunbathing, whereas regular sunbathing is associated with a lower incidence...

Obese and overweight women have an increased risk of breast cancer and worse outcomes at the time of diagnosis. Women tend to gain weight after breast cancer diagnosis and during chemotherapy for early-stage disease, which may in turn increase risk for worse outcomes. We examined if weight gained during adjuvant chemotherapy was associated with worse survival outcomes. We queried our database for data on patients who received adjuvant third-generation chemotherapy for early-stage breast cancer. Univariate and multivariate analyses by Cox regression were performed for survival outcomes across three categories according to BMI variation from start to end of chemotherapy: >0...

Doxorubicin is a broad-spectrum antibiotic and anticancer drug used to treat a variety of human malignancies like breast cancer and leukaemia. Unfortunately, a dose-dependent side effect of this drug is common, representing a major obstacle to its use despite its therapeutic efficacy. Photodynamic therapy is an emerging non-invasive potential adjuvant for conventional cancer treatment. In an attempt to circumvent the dose-limiting effect of doxorubicin, this study aimed to investigate cellular anticancer activity of doxorubicin and sulfonated zinc phthalocyanine-mediated photodynamic therapy on MCF-7 cells alone and in combination...

BACKGROUND: Cost-effectiveness analysis is an important aspect of healthcare, including in Japan, where preventive measures for BRCA1/2 mutation carriers are not covered by health insurance. METHODS: We developed Markov models in a simulated cohort of women aged 35-70 years, and compared outcomes of surveillance with risk-reducing mastectomy (RRM) at age 35, risk-reducing salpingo-oophorectomy (RRSO) at age 45, and both (RRM&RRSO). We used breast and ovarian cancer incidences and adverse event rates from the previous studies, adjuvant chemotherapy, and hormonal therapy rates from the Hereditary Breast and Ovarian Cancer Registration 2015 in Japan, mortality rates from the National Cancer Center Hospital, Japan Society of Clinical Oncology, and Ministry of Health, Labour and Welfare, and direct costs from St...

Oncogenic microRNAs (oncomiRs) accumulate in serum due to their increased stability and thus serve as biomarkers in breast cancer (BC) pathogenesis. Four oncogenic microRNAs (miR-155, miR-19a, miR-181b, and miR-24) and one tumor suppressor microRNA (let-7a) were shown to differentiate between high- and low-risk early breast cancer (EBC) and reflect the surgical tumor removal and adjuvant therapy. Here we applied the longitudinal multivariate data analyses to stochastically model the serum levels of each of the oncomiRs using the RT-PCR measurements in the EBC patients (N = 133) that were followed up 4 years after diagnosis...

PURPOSE: Despite a paucity of evidence, prevention guidelines typically advise avoidance of heavy lifting in an effort to protect against breast cancer-related lymphedema. This study compared acute responses in arm swelling and related symptoms after low- and heavy-load resistance exercise among women at risk of lymphedema while receiving adjuvant taxane-based chemotherapy. METHODS: This is a randomized, cross-over equivalence trial. Women receiving adjuvant taxane-based chemotherapy for breast cancer who had undergone axillary lymph node dissection (n=21) participated in low- (60-65% 1 repetition maximum (RM), two sets of 15-20 repetitions) and heavy-load (85-90% 1RM, three sets of 5-8 repetition) upper-extremity resistance exercise separated by a one-week wash-out period...

PURPOSE: Although axillary lymph node status has traditionally been a key factor in informing adjuvant breast cancer therapy recommendations, this information may be less relevant as our focus shifts more towards tumor biology, particularly in older patients where comorbidity influences treatment decisions and nodal staging and/or surgery may not improve outcomes. We examined patterns of axillary surgery and associations between axillary surgery and receipt of adjuvant treatment in older breast cancer patients...

PURPOSE: Adjuvant internal mammary lymph node (IMN) radiation is often delivered with 2-dimensional techniques that use anatomic landmarks and predetermined depths for field placement and dose specification. In contrast, 3-dimensional planning uses the internal mammary vessels (IMVs) to localize the IMNs for planning. Our purpose was to determine if localization of the involved IMN (i-IMN) by (18)F-labeled fluorodeoxyglucose positron emission tomography-computed tomography ((18)F-FDG PET-CT) offers opportunities to improve treatment...

PURPOSE: HER2 copy number by fluorescence in situ hybridization (FISH) is typically reported relative to the centromere enumeration probe 17 (CEP17). HER2/CEP17 ratio could be impacted by alterations in the number of chromosome 17 copies. Monosomy of chromosome 17 (m17) is found in ~ 1900 cases of early-stage HER2-positive breast cancer annually in the United States; however, the efficacy of HER2-directed trastuzumab therapy in these patients is not well characterized. Here, we retrospectively identified HER2-amplified, stage I-III breast cancers with m17 and characterized the impact of trastuzumab treatment...

Although prognostic markers for early estrogen receptor (ER)-positive breast cancer have been extensively developed, predictive markers for adjuvant endocrine therapy are still lacking. Focusing on the mechanisms underlying endocrine resistance, we investigated whether the endocrine sensitivity of ER-positive breast cancer cells was correlated with the expression of aspartate-β-hydroxylase (ASPH), which is involved in the development of hepatocellular carcinoma. ASPH expression in ER-positive and tamoxifen-resistant breast cancer cells was upregulated by the MAPK and phosphoinositide-3 kinase (PI3K) pathways, which both play pivotal roles in endocrine resistance...

BACKGROUND: The Cancer and Leukemia Group B (CALGB) 9343 trial demonstrated that adjuvant radiation therapy (RT) can be omitted in women 70 years or older, with small (≤2 cm), negative lymph nodes, estrogen receptor (ER)-positive breast cancer. We examined whether RT usage following the CALGB publication had decreased over time and evaluated sociodemographic and clinical factors associated with RT omission. MATERIALS AND METHODS: From the National Cancer Data Base, we analyzed a cohort of 120,308 women aged 70 years or older with stage I, ER-positive breast cancer who underwent lumpectomy...

The benefits of five years of adjuvant endocrine therapy for oestrogen receptor (ER)-positive early breast cancer are well established. However, recent evidence suggests that extended endocrine treatment and ovarian suppression in selected groups of patients have significant advantages. In this article, we review the current evidence for adjuvant endocrine therapy in breast cancer with focus on extended adjuvant endocrine therapy and ovarian suppression, and also highlight the advantages and disadvantages of these therapeutic strategies...

Selective estrogen receptor modulators (SERMs) reduce breast cancer risk. Adoption of SERMs as prevention medication remains low. This is the first study to quantify social, cultural, and psychologic factors driving decision making regarding SERM use in women counseled on breast cancer prevention options. A survey study was conducted with women counseled by a health care provider (HCP) about SERMs. A statistical comparison of responses was performed between those who decided to use and those who decided not to use SERMs...

Triple-negative breast cancer is characterized by the absence of estrogen and progesterone receptors and human epidermal growth factor receptor 2, and is associated with a poorer outcome than other subtypes of breast cancer. Moreover, there are no accurate prognostic genes or effective therapeutic targets, thereby necessitating continued intensive investigation. This study analyzed the genetic mutation landscape in 70 patients with triple-negative breast cancer by targeted exome sequencing of tumor and matched normal samples...

Purpose This study examined the lifestyle and clinical risk factors for lymphedema in a cohort of patients who underwent bilateral breast cancer surgery. Patients and Methods Between 2013 and 2016, 327 patients who underwent bilateral breast cancer surgery were prospectively screened for arm lymphedema as quantified by the weight-adjusted volume change (WAC) formula. Arm perometry and subjective data were collected preoperatively and at regular intervals postoperatively. At the time of each measurement, patients completed a risk assessment survey that reported the number of blood draws, injections, blood pressure readings, trauma to the at-risk arm, and number of flights since the previous measurement...
