    Full Text Available There are many genes which are responsible for developing breast cancer especially, BRCA2 (Breast Cancer 2 and HER2 are extensively involved in developing breast cancer and hence it is the centre of attractions for all the researchers. Nano-particles conjugated with the anti-HER2 monoclonal antibodies are called as “Trastazumab” which directly target the HER2 gene. The major advantage of this technology is that the cells can be prevented before they evolve in to mature stages i.e. metastases production. The BRCA2 gene belongs to the family of tumor suppressor genes and its protein product is responsible for the error free repair mechanisms of DNA. This BRCA2 gene interacts with RAD51 gene to fix the DNA breaks. Mutation in BRCA2 gene such as insertion and deletion leads to breast cancer. More than 800 mutations are found in this gene that lead to increased risk of the breast cancer. Furthermore, BRCA2 gene is also associated with various cancers like prostate, ovarian, fallopian, male breast cancer. Researchers believe that altered products produced due to defects in this gene are unable to interact with the gene RAD51 and cannot repair the DNA. Antisense RNA is the tool which can used to block any RNA or DNA to synthesize its product. In this review we focus in using Antisense RNA against the sense RNA of an altered BRCA2 gene to block the altered affectivity of that gene on the DNA repair mechanism. However, Antisense RNA technique may not help in treating breast cancer, it can better manage the breast cancer to occur.

    Fifteen patients with metastatic breast cancer previously treated with chemotherapy were treated with a regimen consisting of vincristine, Adriamycin, and mitomycin. Eleven patients (73%) responded with three complete and eight partial responses. The median duration of response was eight months. While all four nonresponders died within five months, the median duration of survival of responders was 18 months. Toxicity was significant but tolerable. Thus, this preliminary report suggests that this regimen is active in advanced previously treated breast cancer, providing meaningful remissions with acceptable toxicity.

    Full Text Available Abstract Background Secondary radiation-induced cancers are rare but well-documented as long-term side effects of radiation in large populations of breast cancer survivors. Multiple neoplasms are rare. We report a case of esophageal adenocarcinoma in a patient treated previously for breast cancer and clear cell carcinoma of the kidney. Case presentation A 56 year-old non smoking woman, with no alcohol intake and no familial history of cancer; followed in the National Institute of Oncology of Rabat Morocco since 1999 for breast carcinoma, presented on consultation on January 2011 with dysphagia. Breast cancer was treated with modified radical mastectomy, 6 courses of chemotherapy based on CMF regimen and radiotherapy to breast, inner mammary chain and to pelvis as castration. Less than a year later, a renal right mass was discovered incidentally. Enlarged nephrectomy realized and showed renal cell carcinoma. A local and metastatic breast cancer recurrence occurred in 2007. Patient had 2 lines of chemotherapy and 2 lines of hormonotherapy with Letrozole and Tamoxifen assuring a stable disease. On January 2011, the patient presented dysphagia. Oesogastric endoscopy showed middle esophagus stenosing mass. Biopsy revealed adenocarcinoma. No evidence of metastasis was noticed on computed tomography and breast disease was controlled. Palliative brachytherapy to esophagus was delivered. Patient presented dysphagia due to progressive disease 4 months later. Jejunostomy was proposed but the patient refused any treatment. She died on July 2011. Conclusion We present here a multiple neoplasm in a patient with no known family history of cancers. Esophageal carcinoma is most likely induced by radiation. However the presence of a third malignancy suggests the presence of genetic disorders.

    Cognitive deficits are found in a number of breast-cancer patients who have undergone adjuvant (Cyclophosphamide, Methotrexate, and 5-Fluorouracil (CMF)) chemotherapy, but the underlying mechanisms are still unclear. The objective of this study is to investigate information processing in these patients with concurrent registration of brain activity. Twenty-six breast-cancer patients treated with adjuvant CMF chemotherapy and a control group of 23 stage I breast-cancer patients not treated with chemotherapy were examined. Mean time since treatment for the CMF patients was 5.1 years after the last CMF course, and for the control patients 3.6 years after termination of radiotherapy. An information processing task was administered with concurrent EEG registration. Reaction times and the amplitudes and latencies of an Event Related Potential component (P3) in different task conditions related to input, central, and output processing of information were studied. Significant differences in latency and amplitude of the P3 component were found between the treatment groups with an earlier and reduced P3 in the chemotherapy group. Patients treated with chemotherapy had longer reaction times (although not significantly different) than the control group on all task conditions. Our data provide further evidence for long-term neurocognitive problems in breast-cancer patients treated with adjuvant (CMF) chemotherapy and offer new information regarding abnormalities in brain functioning in these patients.

    OBJECTIVE To study the local recurrence and the role of whole breast radiotherapy for early breast cancer treated by conservative surgery.METHODS From April 1990 to December 2000, 49 patients with early primary breast cancer were treated by conservative surgery in our hospital. The cases were comprised of Stage 0, 1; Stage Ⅰ, 31; and Stage Ⅱa,17. Forty cases underwent quadrantectomy plus axillary lymph node dissection, and the other 9 cases had lumpectomy alone. Irradiation, which was received by 39 patients, was administered by using low tangential half fields with 6 MV X-ray to decrease the pulmonary irradiative volume.The dose to the whole breast was 45 Gy/22~23f/4.5W, then a 15 Gy boost dose was delivered to the tumor bed by an electron beam. The other patients underwent an irradiated regional field according to postoperative pathology.RESULTS All patients were followed-up for 10 years or more. The 10year local recurrence rates, distant metastasis rates and survival rates were 6.1%, 4.1% and 98.0% respectively. All of the 3 patients who had a local recurrence had infiltrative carcinomas and negative lymph nodes.The 10-year local recurrence rate was higher (2.6% vs. 20.0%) with nonpostoperative whole breast radiotherapy, but the statistical difference was not marked because of the low number of cases. All of the recurrent lesions localized within 3 cm of the primary lesion.CONCLUSION Original recurrence of the tumor was the main type of local recurrence. Radiotherapy after conservative surgery is very essential.After conservative surgery it is feasible that irradiation can be delivered alone to the neighboring region of the tumor bed. Partial breast radiotherapy can substitute for whole breast radiotherapy.

    Full Text Available Abstract Background Many studies have reported an increased risk of developing a second primary malignancy (SPM of the breast in women treated for thyroid cancer. In this study, we investigated several potential risk factors for this association. The aim of this retrospective cohort study was to identify a subgroup of women surgically treated for papillary thyroid cancer that may benefit from more careful breast cancer screening. Methods A total of 101 women surgically treated for papillary thyroid cancer from 1996 to 2009 with subsequent follow-up were interviewed by phone regarding personal risk factors and lifestyle habits. Only 75 questionnaires could be evaluated due to a 25.7% rate of patients not retrieved or refusing the interview. Data analysis was performed using a multivariate logistic model. Results The standardised incidence ratio (SIR for breast cancer was 3.58 (95% IC 1.14 - 8.37. Our data suggest a protective effect of multiparity on the development of a SPM of the breast (O.R. 0.15; 95% IC 0.25 - 0.86. Significant associations were not found with other known risk factors including Body Mass Index (BMI, age at first tumour, concurrent metabolic diseases, smoking, physical activity and familiarity. Conclusions This study confirms that a higher incidence of SPM of the breast is observed in women treated for papillary thyroid cancer. Additionally, this risk is increased by nulliparity, thus a strict breast screening program for nulliparous women treated for thyroid cancer may be advisable.

    Breast cancer is the most common cancer among women worldwide and novel therapeutic agents are needed to treat this disease. The plant-based alkaloid berberine has potential therapeutic applications for breast cancer, although a better understanding of the genes and cellular pathways regulated by this compound is needed to define the mechanism of its action in cancer treatment. In this review, the molecular targets of berberine in various cancers, particularly breast cancer, are discussed. Berberine was shown to be effective in inhibiting cell proliferation and promoting apoptosis in various cancerous cells. Some signaling pathways affected by berberine, including the MAP (mitogen-activated protein) kinase and Wnt/β-catenin pathways, are critical for reducing cellular migration and sensitivity to various growth factors. This review will discuss recent studies and consider the application of new prospective approaches based on microRNAs and other crucial regulators for use in future studies to define the action of berberine in cancer. The effects of berberine on cancer cell survival and proliferation are also outlined.

    2015-01-01

    Bone is a hormonally responsive organ. Sex hormones and calcium regulating hormones, including parathyroid hormone, 1-25 dihydroxy vitamin D, and calcitonin, have effects on bone resorption and bone deposition. These hormones affect both bone quality and bone quantity. The sex hormone estrogen inhibits bone resorption, and estrogen therapy has been developed to prevent and treat osteoporosis. Androgens are an important source of estrogen through the action of the enzyme aromatase and may themselves stimulate bone formation. Hence, the sex steroids play a role in bone metabolism. Breast cancer and prostate cancer are frequently hormonally responsive and may be treated with antiestrogens or antiandrogens respectfully. In addition, chemotherapy and supportive medications may alter the patient's endocrine system. In general, the suppression of sex hormones has a predictable affect on bone health, as seen by loss of bone mineral density and increased risk of fragility fractures. The bone toxicity of cancer-directed endocrine therapy can be mitigated through screening, counseling on optimization of calcium and vitamin D intake, exercise, and other lifestyle/behavioral actions, as well as the use of medications when the fracture risk is high. Maintaining bone health in patients who are treated with endocrine therapy for breast and prostate cancer is the focus of this review.

    Full Text Available Abstract Background Prognostic factors in locally advanced breast cancer treated with neoadjuvant chemotherapy differ from those of early breast cancer. The purpose of this study was to identify the clinical significance of potential predictive and prognostic factors in breast cancer patients treated by neoadjuvant chemotherapy. Methods A total of 145 stage II and III breast cancer patients received neoadjuvant docetaxel/doxorubicin chemotherapy were enrolled in this study. We examined the clinical and biological factors (ER, PR, p53, c-erbB2, bcl-2, and Ki-67 by immunohistochemistry. We analyzed clinical outcome and their correlation with clinicopathologic parameters. Results Among the clinicopathologic parameters investigated, none of the marker was correlated with response rate (RR except triple negative phenotype. Patients with triple negative phenotype showed higher RR (83.0% in triple negative vs. 62.2% in non-triple negative, p = 0.012 and pathologic complete RR (17.0% in triple negative vs. 3.1% in non-triple negative, p = 0.005. However, relapse free survival (RFS and overall survival (OS were significantly shorter in triple negative breast cancer patients (p p = 0.021, respectively. Low histologic grade, positive hormone receptors, positive bcl-2 and low level of Ki-67 were associated with prolonged RFS. In addition, positive ER and positive bcl-2 were associated with prolonged OS. In our homogeneous patient population, initial clinical stage reflects RFS and OS more precisely than pathologic stage. In multivariate analysis, initial clinical stage was the only significant independent prognostic factor to impact on OS (hazard ratio 3.597, p = 0.044. Conclusion Several molecular markers provided useful predictive and prognostic information in stage II and III breast cancer patients treated with neoadjuvant docetaxel/doxorubicin chemotherapy. Triple negative phenotype was associated with shorter survival, even though it was associated

    2017-02-01

    Background: Possible targeted therapies for metastatic triple negative breast cancer (TNBC) include cytotoxic chemotherapy that causes interstrand breaks (platinum-based drugs). The excision repair cross-complementation 1 (ERCC1) enzyme plays an essential role in the nucleotide excision repair pathway, removing platinum-induced DNA adducts and contributing to cisplatin resistance. Detecting ERCC1 overexpression is important in considering treatment options for metastatic TNBC, including individualized approaches to therapy, and may facilitate improved responses or reduction of unnecessary toxicity. We hypothesized that assigning cisplatin based on pretreatment ERCC1 expression would improve response and survival. This study was conducted to assess the impact of ERCC1 expression on PFS, OS and response rates in metastatic triple negative breast cancer patients treated with platinum-based chemotherapy. Methods: From June 2012 to November 2013, 52 metastatic triple negative breast cancer patients were enrolled. ERCC1 protein expression was detected from pretreatment biopsies by Immunohistochemistry. All patients received cisplatin plus paclitaxel. The primary end point was the impact of ERCC1 expression on PFS and OS. Results: 34 patients (65.4%) showed positive ERCC1 expression while 18 (34.6%) proved negative. Positive ERCC1 expression was associated with short PFS (median, 5 months vs. 7 months; P = 0.043), short OS (median, 9 months vs. 11 months; P = 0.033) and poor response to cisplatin based chemotherapy (P = 0.046). Conclusions: This prospective study further validated ERCC1 as a reliable biomarker for customized chemotherapy in metastatic triple negative breast cancer patients. High expression of ERCC1 was thereby fond to be significantly associated with poor outcome in patients treated with platinum based chemotherapy.

    Breast cancer is a leading cause of cancer-related deaths in women worldwide. Although tumorectomy, radiotherapy, chemotherapy and hormone replacement therapy have been used for the treatment of breast cancer, there is no effective therapy for patients with invasive and metastatic breast cancer. Immunotherapy may be proved effective in treating patients with advanced breast cancer. Breast cancer immunotherapy includes antibody based immunotherapy, cancer vaccine immunotherapy, adoptive T cell transfer immunotherapy and T cell receptor gene transfer immunotherapy. Antibody based immunotherapy such as the monoclonal antibody against HER-2/neu (trastuzumab) is successfully used in the treatment of breast cancer patients with over-expressed HER-2/neu, however, HER-2/neu is over-expressed only in 25-30% of breast cancer patients. Cancer vaccine immunotherapy is a promising method to treat cancer patients. Cancer vaccines can be used to induce specific anti-tumor immunity in breast cancer patients, but cannot induce objective tumor regression. Adoptive T cell transfer immunotherapy is an effective method in the treatment of melanoma patients. Recent advances in anti-tumor T cell generation ex vivo and limited clinical trial data have made the feasibility of adoptive T cell transfer immunotherapy in the treatment of breast cancer patients. T cell receptor gene transfer can redirect the specificity of T cells. Chimeric receptor, scFv(anti-HER-2/neu)/zeta receptor, was successfully used to redirect cytotoxic T lymphocyte hybridoma cells to obtain anti-HER-2/neu positive tumor cells, suggesting the feasibility of treatment of breast cancer patients with T cell receptor gene transfer immunotherapy. Clinical trials will approve that immunotherapy is an effective method to cure breast cancer disease in the near future. Cellular & Molecular Immunology.

    Aromatase inhibitors (AI), either alone or together with chemotherapy, have become the standard adjuvant treatment for postmenopausal, estrogen receptor-positive (ER+) breast cancer. Although AIs improve overall survival, resistance is still a major clinical problem, thus additional biomarkers...... predictive of outcome of ER+ breast cancer patients treated with AIs are needed. Global gene expression analysis was performed on ER+ primary breast cancers from patients treated with adjuvant AI monotherapy; half experienced recurrence (median follow-up 6.7 years). Gene expression alterations were validated...... by qRT-PCR, and functional studies evaluating the effect of siRNA-mediated gene knockdown on cell growth were performed. Twenty-six genes, including TFF3, DACH1, RGS5, and GHR, were shown to exhibit altered expression in tumors from patients with recurrence versus non-recurrent (fold change ≥1.5, p

    Breast cancer in young women has been shown to have an aggressive behavior and worse prognosis. Studies evaluating young women enrolled in clinical trials of neoadjuvant chemotherapy have shown that age is a determinant factor in the achievement of a pathological complete response (pCR). In this study, we sought to analyze the outcomes of young patients treated with neoadjuvant chemotherapy at a single institution. 1639 patients treated with neoadjuvant chemotherapy were included. 316 patients ≤40 years were compared with 1323 patients aged >40 years regarding the achievement of a pCR (defined as no invasive residual tumor in the breast or lymph nodes). Disease-free survival (DFS) and overall survival were compared between groups according to pCR status and subtype, defined by hormone receptor (HR) and HER2 status. Young women were more likely to have a pCR than their older counterparts (37.4 vs. 26.3 %, P world clinical setting, the achievement of a pCR was an independently significant protective factor for recurrence across all subtypes and ages, except for HR+, HER2- disease in young women.

    Full Text Available BACKGROUND: Data on birth outcome and offspring health after the appearance of breast cancer are limited. The aim of this study was to assess the risk of adverse birth outcomes in women previously treated for invasive breast cancer compared with the general population of mothers. METHODS AND FINDINGS: Of all 2,870,932 singleton births registered in the Swedish Medical Birth Registry during 1973-2002, 331 first births following breast cancer surgery--with a mean time to pregnancy of 37 mo (range 7-163--were identified using linkage with the Swedish Cancer Registry. Logistic regression analysis was used. The estimates were adjusted for maternal age, parity, and year of delivery. Odds ratios (ORs and 95% confidence intervals (CIs were used to estimate infant health and mortality, delivery complications, the risk of preterm birth, and the rates of instrumental delivery and cesarean section. The large majority of births from women previously treated for breast cancer had no adverse events. However, births by women exposed to breast cancer were associated with an increased risk of delivery complications (OR 1.5, 95% CI 1.2-1.9, cesarean section (OR 1.3, 95% CI 1.0-1.7, very preterm birth (<32 wk (OR 3.2, 95% CI 1.7-6.0, and low birth weight (<1500 g (OR 2.9, 95% CI 1.4-5.8. A tendency towards an increased risk of malformations among the infants was seen especially in the later time period (1988-2002 (OR 2.1, 95% CI 1.2-3.7. CONCLUSIONS: It is reassuring that births overall were without adverse events, but our findings indicate that pregnancies in previously treated breast cancer patients should possibly be regarded as higher risk pregnancies, with consequences for their surveillance and management.

    2015-06-01

    Purpose: To report dosimetry and early toxicity data in breast cancer patients treated with postoperative proton radiation therapy. Methods and Materials: From March 2013 to April 2014, 30 patients with nonmetastatic breast cancer and no history of prior radiation were treated with proton therapy at a single proton center. Patient characteristics and dosimetry were obtained through chart review. Patients were seen weekly while on treatment, at 1 month after radiation therapy completion, and at 3- to 6-month intervals thereafter. Toxicity was scored using Common Terminology Criteria for Adverse Events version 4.0. Frequencies of toxicities were tabulated. Results: Median dose delivered was 50.4 Gy (relative biological equivalent [RBE]) in 5 weeks. Target volumes included the breast/chest wall and regional lymph nodes including the internal mammary lymph nodes (in 93%). No patients required a treatment break. Among patients with >3 months of follow-up (n=28), grade 2 dermatitis occurred in 20 patients (71.4%), with 8 (28.6%) experiencing moist desquamation. Grade 2 esophagitis occurred in 8 patients (28.6%). Grade 3 reconstructive complications occurred in 1 patient. The median planning target volume V95 was 96.43% (range, 79.39%-99.60%). The median mean heart dose was 0.88 Gy (RBE) [range, 0.01-3.20 Gy (RBE)] for all patients, and 1.00 Gy (RBE) among patients with left-sided tumors. The median V20 of the ipsilateral lung was 16.50% (range, 6.1%-30.3%). The median contralateral lung V5 was 0.34% (range, 0%-5.30%). The median maximal point dose to the esophagus was 45.65 Gy (RBE) [range, 0-65.4 Gy (RBE)]. The median contralateral breast mean dose was 0.29 Gy (RBE) [range, 0.03-3.50 Gy (RBE)]. Conclusions: Postoperative proton therapy is well tolerated, with acceptable rates of skin toxicity. Proton therapy favorably spares normal tissue without compromising target coverage. Further follow-up is necessary to assess for clinical outcomes and cardiopulmonary

  12. Potential role of pemetrexed in metastatic breast cancer patients pre-treated with anthracycline or taxane

    Institute of Scientific and Technical Information of China (English)

    Li-Yan Zhou; Ye-Hui Shi; Yong-Sheng Jia; Zhong-Sheng Tong

    2015-01-01

    Objectives: This article reviews pharmacology, pharmacokinetic properties, clinical efficacy, and safety in metastatic breast cancer patients, as well as the predictive biomarkers for outcome of treatment with pemetrexed-based regimens. Methods: PubMed, Embase, OVID, and the Cochrane Library databases were searched from the beginning of each database without any limitations to the date of publication. Search terms were‘‘pemetrexed’’ or‘‘LY231514’’ or“Alimta”,“metastatic breast cancer”, and“advanced breast cancer”. Results: There were 15 studies (n ¼ 1002) meeting our criteria for evaluation. Eight single-agent trials (n ¼ 551) and seven using combinations with other agents (n ¼ 451) were identified that evaluated pemetrexed for use in patients with metastatic breast cancer. Response rates to pemetrexed as a single agent varied from 8%to 31%, and with combination therapy have been reported to be between 15.8% and 55.7%. With routine supplementation of patients with folic acid, dexamethasone, and vitamin B12, the toxicity profile of these patients was mild, including dose-limiting neutropenia and thrombocytopenia, as well as lower grades of reversible hepatotoxicity and gastrointestinal toxicity. Expression of thymidylate synthase (TS) and other biomarkers are associated with the prognosis and sensitivity for pemetrexed in breast cancer. Conclusion: Pemetrexed has shown remarkable activity with acceptable toxicities for treatment of metastatic breast cancer patients. Translational research on pemetrexed in breast cancer identified biomarkers as well as additional genes important to its clinical activity and toxicity. Further research is needed to clarify the role of pemetrexed in breast cancer treatment in order to guide oncologists. Copyright © 2015, Chinese Medical Association Production.

    Brain metastasis (BM) is increasingly diagnosed in Her2 positive breast cancer (BC) patients. Lack of effective treatment to breast cancer brain metastases (BCBMs) is probably due to inability of the current therapeutic agents to cross the blood-brain barrier. The central nervous system (CNS) response rate in BCBM patients was reported to improve from 2.6%-6% (lapatinib) to 20%-65% (lapatinib in combination with capecitabine). Lapatinib is a poor brain penetrant. In this study, we evaluated the CNS penetration of capecitabine and hoped to interpret the mechanism of the improved CNS response from the pharmacokinetic (PK) perspective. Capecitabine does not have antiproliferative activity and 5-fluorouracil (5-FU) is the active metabolite. Capecitabine was orally administered to mouse returning an unbound brain-to-blood ratio (Kp,uu,brain) at 0.13 and cerebrospinal fluid (CSF)-to-unbound blood ratio (Kp,uu,CSF) at 0.29 for 5-FU. Neither free brain nor CSF concentration of 5-FU can achieve antiproliferative concentration for 50% of maximal inhibition of cell proliferation of 4.57 µM. BCBM mice were treated with capecitabine monotherapy or in combination with lapatinib. The Kp,uu,brain value of 5-FU increased to 0.17 in the brain tumor in the presence of lapatinib, which is still far below unity. The calculated free concentration of 5-FU and lapatinib in the brain tumor did not reach the antiproliferative potency and neither treatment showed antitumor activity in the BCBM mice. The CNS penetration of 5-FU in human was predicted based on the penetration in preclinical brain tumor, CSF, and human PK and the predicted free CNS concentration was below the antiproliferative potency. These results suggest that CNS penetration of 5-FU and lapatinib are not desirable and development of a true CNS penetrable therapeutic agent will further improve the response rate for BCBM.

    2006-09-01

    Full Text Available Abstract Background Female genital tuberculosis is an uncommon disease that is rarely diagnosed in developed countries. Case presentation A 61-year-old postmenopausal woman who had undergone surgery and treated with adjuvant chemotherapy for infiltrating ductal carcinoma of the breast five years ago, presented with bloody vaginal discharge, fatigue, weight loss, and low grade fevers at night for two months. Histological examination of the endometrium, done based on the suspicion of a second primary cancer due to the tamoxifen therapy, revealed a granulomatous reaction. Liquid and solid mycobacterial cultures of the tissues were performed. Although the acid fast staining was negative, the liquid culture was positive for Mycobacterium tuberculosis. Involvement of other systems was not detected. The patient was treated with a three-drug antituberculosis regimen for 9 months and recovered fully. Conclusion Female genital tuberculosis is a rare but curable disease that should be included in the differential diagnosis of women with menstrual problems. Early diagnosis is important and may prevent unnecessary invasive procedures for the patient.

    This infographic shows the Breast Cancer Subtypes in Women. It’s important for guiding treatment and predicting survival. Know the Science: HR = Hormone receptor. HR+ means tumor cells have receptors for the hormones estrogen or progesterone, which can promote the growth of HR+ tumors. Hormone therapies like tamoxifen can be used to treat HR+ tumors. HER2 = Human epidermal growth Factor receptor, HER2+ means tumor cells overexpress (make high levels of) a protein, called HE2/neu, which has been shown to be associated with certain aggressive types of breast cancer. Trastuzumab and some other therapies can target cells that overexpress HER2. HR+/HER2, aka “LuminalA”. 73% of all breast cancer cases: best prognosis, most common subtype for every race, age, and poverty level. HR-/HER2, aka “Triple Negative”: 13% of all breast cancer cases, Worst prognosis, Non-Hispanic blacks have the highest rate of this subtype at every age and poverty level. HR+/HER2+, aka “Luminal B”, 10% of all breast cancer cases, little geographic variation by state.

    Breast cancer is one of the most common female malignant tumors. According to data statistics, the incidence of breast cancer was 7% to 10% for a variety of malignant tumors, being only lower than that of uterine cancer. The methods of treating breast cancer are given priority over operative treatment and combined with chemotherapy and radiotherapy. However, exosmosis of chemotherapeutic drugs is a common complication of chemotherapy. Exosmosis of drugs can stimulate local organs to induce acute inflammatory reaction and necrosis, which finally lead to wound infection and difficulty in healing. In December 2013, a patient with full-thickness wound (an area of 5 × 3 cm) dehiscence at the completion of the second phase of chemotherapy for left breast cancer after radical operation was admitted to our department. Her wound had healed after radical operation. The patient followed an integrative therapy treatment protocol that consisted of an external application of a phytomedicine called Sanguis Draconis and combined with a series of conventional treatments, including 3M Transparent Dressing moist therapy, increase in nutrition, and prevention therapies for infection. The patient's integrative treatment program resulted in complete wound healing, and the successful completion of the late 6 courses of chemotherapy. The article describes the nursing experiences associated with this case study.

    A significant percentage of breast cancer victims will suffer from metastases indicating that new approaches to preventing breast cancer metastasis are thus needed. Dietary stearate (ST) and chemotherapy have been shown to reduce breast cancer metastasis. We tested the complementary use of dietary ST with a taxol-based chemotherapy which work through separate mechanisms to reduce breast cancer metastasis. We therefore carried out a prevention study in which diets were initiated prior to human MDA-MB-435 cancer cells being injected into the host and a treatment study in which diets were combined with paclitaxel (PTX). Using an orthotopic athymic nude mouse model and three diets [corn oil (CO) control diet, low fat (LF) or ST] the prevention study demonstrated that the ST diet decreased the incidence of lung metastasis by 50 % compared to both the LF and CO diets. The ST diet also reduced the number and size of metastatic lung nodules compared to the LF diet. Results of the treatment study indicated that both the CO and ST diets decreased the number of mice with lung metastasis compared to the LF diet. Both CO and ST also decreased the number of lung metastases per mouse compared to the LF diet however only the ST diet cohort was significant. Histomorphometric analysis of the lung tumor tissue indicated that the ST diet plus PTX decreased angiogenesis compared to the LF diet plus PTX. In conclusion these results support combining diet with chemotherapy in both treatment and prevention settings.

    2005-01-01

    Full Text Available Context: Hypofractionated breast radiotherapy (RT, although convenient for patients and health care systems, could have a negative impact on normal tissues such as lung. Aims: To evaluate radiation-induced lung toxicity in early breast-cancer patients treated by hypofractionated RT. Settings and Design: We have been using the 42.5 Gy/16 fractions RT schedule since May 2003. As large fraction size is related to increased normal tissue toxicity we intended to investigate the possible radiation-induced lung toxicity to these patients, by performing high-resolution computed tomography (HRCT 6 months after the completion of the treatment. Methods and Material: A group of 30 consecutive early breast cancer patients (T1-2N0M0 have been treated by the above-mentioned RT schedule, using a pair of opposing tangential fields. The impact of chemotherapy and hormonotherapy and various breast size-related parameters on HRCT lung changes were investigated. Acute skin and breast tissue reactions were also recorded. Statistical analysis: used Correlation of numerical variables was investigated by Pearson correlation coefficient. Logistic regression analysis was used to investigate correlation between HRCT findings (present vs absent with other variables. Results: Minimal HRCT findings were evident in 15/30 patients. These included small septal lines, linear and subpleural opacities and to a lesser extend, focal-ground glass opacification. The HRCT findings were positively correlated only to field separation (distance between the entrance points of the tangential beams on the breast (H.R.=1.33, 95% CI: 1.013-1.75. Conclusions: The short 16-fraction RT schedule for early breast-cancer patients appears to have a minor effect on the underlying lung parenchyma.

    Hypoxia is a major cause of treatment resistance in breast cancer. Single-walled carbon nanotubes (SWCNTs) exhibit unique properties that make them promising candidates for breast cancer treatment. In the present study, a new functionalized single-walled carbon nanotube carrying oxygen was synthesized; it was determined whether this material could increase chemosensitivity and radiosensitivity of human breast cancer cell lines, and the underlying mechanisms were investigated. MDA-MB-231 cells growing in folic acid (FA) free medium, MDA-MB-231 cells growing in medium containing FA and ZR-75-1 cells were treated with chemotherapy drugs or radiotherapy with or without tombarthite-modified-FA-chitosan (R-O2-FA-CHI)-SWCNTs under hypoxic conditions, and the cell viability was determined by water-soluble tetrazolium salts-1 assay. The cell surviving fractions were determined by colony forming assay. Cell apoptosis induction was monitored by flow cytometry. Expression of B-cell lymphoma 2 (Bcl-2), survivin, hypoxia-inducible factor 1-α (HIF-1α), multidrug resistance-associated protein 1 (MRP-1), P-glycoprotein (P-gp), RAD51 and Ku80 was monitored by western blotting. The novel synthesized R-O2-FA-CHI-SWCNTs were able to significantly enhance the chemosensitivity and radiosensitivity of human breast cancer cell lines and the material exhibited its expected function by downregulating the expression of Bcl-2, survivin, HIF-1α, P-gp, MRP-1, RAD51 and Ku80.

    Few studies have reported reproductive outcomes after breast cancer chemotherapy. The relationship between anti-Müllerian hormone (AMH) concentrations and the occurrence of subsequent pregnancies in women after chemotherapy for breast cancer was investigated. Women aged 18-43 years treated with chemotherapy for invasive breast cancer between May 2005 and January 2011 were retrospectively identified. Exclusion criteria were previous gonadotoxic treatment, oophorectomy or hysterectomy. Measurement of AMH took place before, during chemotherapy and at distant time points after the end of chemotherapy (4 months to 5.5 years). Seventeen out of 134 patients experienced 28 spontaneous pregnancies (median follow-up: 59 months). Neither baseline AMH (divided into quartiles) nor end-of-chemotherapy AMH (detectable versus undetectable) were significantly associated with the occurrence of pregnancy. Chemotherapy regimen with anthracyclines was associated with a greater probability of pregnancy compared with a taxane-containing regimen (hazard ratio 4.75; (95% CI 1.76 to 12.8); P = 0.002). Five-year disease-free survival and overall survival rates were 60% (95% CI: 51 to 70; relapse, n = 48) and 88% (95% CI 82 to 95; deaths, n = 21), respectively. AMH did not predict the occurrence of pregnancy. Additional studies assessing ovarian reserve and reproductive outcomes after breast cancer are required.

    Aromatase inhibitors (AI), either alone or together with chemotherapy, have become the standard adjuvant treatment for postmenopausal, estrogen receptor-positive (ER+) breast cancer. Although AIs improve overall survival, resistance is still a major clinical problem, thus additional biomarkers predictive of outcome of ER+ breast cancer patients treated with AIs are needed. Global gene expression analysis was performed on ER+ primary breast cancers from patients treated with adjuvant AI monotherapy; half experienced recurrence (median follow-up 6.7 years). Gene expression alterations were validated by qRT-PCR, and functional studies evaluating the effect of siRNA-mediated gene knockdown on cell growth were performed. Twenty-six genes, including TFF3, DACH1, RGS5, and GHR, were shown to exhibit altered expression in tumors from patients with recurrence versus non-recurrent (fold change ≥1.5, p proliferation, growth, and development. TFF3, which encodes for trefoil factor 3 and is an estrogen-responsive oncogene shown to play a functional role in tamoxifen resistance and metastasis of ER+ breast cancer, was also shown to be upregulated in an AI-resistant cell line model, and reduction of TFF3 levels using TFF3-specific siRNAs decreased the growth of both the AI-resistant and -sensitive parental cell lines. Moreover, overexpression of TFF3 in parental AI-sensitive MCF-7/S0.5 cells resulted in reduced sensitivity to the AI exemestane, whereas TFF3 overexpression had no effect on growth in the absence of exemestane, indicating that TFF3 mediates growth and survival signals that abrogate the growth inhibitory effect of exemestane. We identified a panel of 26 genes exhibiting altered expression associated with disease recurrence in patients treated with adjuvant AI monotherapy, including TFF3, which was shown to exhibit a growth- and survival-promoting effect in the context of AI treatment.

    Purpose: To investigate whether the expression of p53 binding protein 1 (53BP1) has prognostic significance in a cohort of early-stage breast cancer patients treated with breast-conserving surgery and radiotherapy (BCS+RT). Methods and Materials: A tissue microarray of early-stage breast cancer treated with BCS+RT from a cohort of 514 women was assayed for 53BP1, estrogen receptor, progesterone receptor, and HER2 expression by immunohistochemistry. Through log-rank tests and univariate and multivariate models, the staining profile of each tumor was correlated with clinical endpoints, including ipsilateral breast recurrence-free survival (IBRFS), distant metastasis-free survival (DMFS), cause-specific survival (CSS), recurrence-free survival (RFS), and overall survival (OS). Results: Of the 477 (93%) evaluable tumors, 63 (13%) were scored as low. Low expression of 53BP1 was associated with worse outcomes for all endpoints studied, including 10-year IBRFS (76.8% vs. 90.5%; P=.01), OS (66.4% vs. 81.7%; P=.02), CSS (66.0% vs. 87.4%; P<.01), DMFS (55.9% vs. 87.0%; P<.01), and RFS (45.2% vs. 80.6%; P<.01). Multivariate analysis incorporating various clinico-pathologic markers and 53BP1 expression found that 53BP1 expression was again an independent predictor of all endpoints (IBRFS: P=.0254; OS: P=.0094; CSS: P=.0033; DMFS: P=.0006; RFS: P=.0002). Low 53BP1 expression was also found to correlate with triple-negative (TN) phenotype (P<.01). Furthermore, in subset analysis of all TN breast cancer, negative 53BP1 expression trended for lower IBRFS (72.3% vs. 93.9%; P=.0361) and was significant for worse DMFS (48.2% vs. 86.8%; P=.0035) and RFS (37.8% vs. 83.7%; P=.0014). Conclusion: Our data indicate that low 53BP1 expression is an independent prognostic indicator for local relapse among other endpoints in early-stage breast cancer and TN breast cancer patients treated with BCS+RT. These results should be verified in larger cohorts of patients to validate their clinical

    Full Text Available The purpose of this case report is to show the potential benefit of Korean medicine therapy for treating multiple metastatic breast cancer. A 45-year-old Korean woman was diagnosed with right breast invasive ductal carcinoma in August 2012 but did not receive any treatment until October 2015 when she was diagnosed with stage 4 right breast cancer with multiple liver, bone, mesentery, retroperitoneum, and axillary lymph node metastases. After chemo-port insertion, she was treated with palliative chemotherapy and the first line of trastuzumab and paclitaxel, and the port was removed due to port infection. To treat sepsis, vancomycin and tazoperan were administered, before the third line of trastuzumab and paclitaxel was carried out. However, the patient gave up chemotherapy due to vancomycin-resistant enterococci and general weakness. Later, she received Korean medicine therapy with wild ginseng pharmacopuncture, distilled Soramdan S, Hae, and Jeobgoldan for 8 months, which led to a significant decrease of the multiple metastases. The patient was able to start walking again with the help of a walking stick. However, a new metastatic lesion was found on the right adrenal gland. This case suggests that the combination of chemotherapy and Korean medicine therapy may be valuable. Further research is indicated.

    Infections related to anti-HER2 monoclonal antibodies (mAbs), trastuzumab and pertuzumab, have been reported in clinical trials. It is not yet clear whether these drugs increase an infection risk or not. We performed a systematic review and meta-analysis to assess the risk of infections associated with anti-HER2 mAbs. We searched PubMed and the ASCO online database of meeting abstracts up to January 2014 for relevant clinical trials. Eligible studies included randomized controlled trials of trastuzumab or pertuzumab for breast cancer patients that reported adequate safety data for grade 3-4 infection, febrile neutropenia, neutropenia, or leukopenia. The summary incidence, relative risk (RR), and 95 % confidence intervals (CIs) were calculated. A total of 10,094 patients from 13 trials were included. The use of trastuzumab was associated with an increased risk of high-grade infection (RR 1.21, 95 % CI 1.07-1.37, P = 0.002) and febrile neutropenia (RR 1.28, 95 % CI 1.08-1.52, P = 0.004). The incidence of high-grade infection and febrile neutropenia due to trastuzumab was 8.5 % (95 % CI 4.5-15.4 %) and 12.0 % (95 % CI 8.1-17.4 %), respectively. There was no significant increase in a risk of high-grade neutropenia or leukopenia in patients receiving trastuzumab. Treatment with trastuzumab is associated with a significantly higher risk of high-grade infection and febrile neutropenia. Our findings suggest an importance of close monitoring for any signs of infections in patients treated with trastuzumab.

    Surgical therapy for occult breast cancer has traditionally centered on mastectomy; however, breast conservation with whole breast radiotherapy followed by axillary lymph node dissection has shown equivalent results. Patients with breast cancer in pregnancy can be safely and effectively treated; given a patient's pregnancy trimester and stage of breast cancer, a clinician must be able to guide therapy accordingly. Male breast cancer risk factors show strong association with BRCA2 mutations, as well as Klinefelter syndrome. Several retrospective trials of surgical therapy in stage IV breast cancer have associated a survival advantage with primary site tumor extirpation.

    Male breast cancer is rare, with some pathological and radiological differences from female breast cancer. There is less familiarity with the imaging appearances of male breast cancer, due to its rarity and the more variable use of preoperative imaging. This review will illustrate the commonest imaging appearances of male breast cancer, with emphasis on differences from female breast cancer and potential pitfalls in diagnosis, based on a 10 year experience in our institution.

    Multi-modality diagnosis techniques are more and more replacing traditional medical imaging for breast cancer detection. Newly emerging advances in both intelligent cancer detection systems and lipidomics technologies offer an excellent opportunity to detect tumors and to understand regulation at the molecular level in many diseases such as cancer. In this paper, we present a detailed computer-aided diagnosis (CAD) systems combining motion artefact reduction and automated feature extraction and classification, and a novel data mining approach for visualization of gene therapy leading to apoptosis in U87 MG glioblastoma cells, a secondary tumor of breast cancer. The achieved results show that the CAD system represents a robust and integrative tool for reliable small contrast enhancing lesions. Graph-clustering methods are introduced as powerful correlation networks which enable a simultaneous exploration and visualization of co-regulation in glioblastoma data. These new paradigms are providing unique "fingerprints" by revealing how the intricate interactions at the lipidome level can be employed to induce apoptosis (cell death) and are thus opening a new window to biomedical frontiers.

    Background: Breast cancer survivors make up a growing population facing treatment that poses long-standing adverse effects including chemotherapy-related body function changes and/or pain. There is limited knowledge of patients’ lived experiences of chemotherapy-induced pain (CHIP). Objective: The aim of this study was to explore CHIP and any long-standing pain experiences in the lifeworld of breast cancer survivors. Methods: Fifteen women participated in a follow-up interview a year after having experienced CHIP. They were interviewed from a lifeworld perspective; the interviews were analyzed through guided phenomenology reflection. Results: A past perspective: CHIP is often described in metaphors, leads to changes in a patient’s lifeworld, and impacts lived time. The women become entirely dependent on others but at the same time feel isolated and alone. Existential pain was experienced as increased vulnerability. Present perspective: Pain engages same parts of the body, but at a lower intensity than during CHIP. The pain creates time awareness. Expected normality in relationships/daily life has not yet been achieved, and a painful existence emerges in-between health and illness. Future perspective: There are expectations of pain continuing, and there is insecurity regarding whom to turn to in such cases. A painful awareness emerges about one’s own and others’ fragile existence. Conclusions: Experiencing CHIP can impact the lifeworld of women with a history of breast cancer. After CHIP, there are continued experiences of pain that trigger insecurity about whether one is healthy. Implications for Practice: Cancer survivors would likely benefit from communication and information about and evaluation of CHIP. PMID:26632880

    Full Text Available Breast cancer is currently one of the most common malignant tumors of human race and at the same it is the most frequent cancer of female population. The war and post-war migrations of population have significantlychanged the demographic and age structure in Bosnia and Herzegovina. Absence of a National Cancer Register and a unique database on malignant diseases makes monitoring of breast cancer even more difficult.Theobjectiveof this retrospective study was to analyze the incidence of breast cancer in Zenica-Doboj Canton, to conduct a survey based on the age of patients in the five-year period starting from 1 January 2001 until 30 November 2005 and results of the study have been compared with 1990. All the patients were treated surgically with pre-surgical clinical examination, ultra-sound examination and mamography, and pathohistological verification of cancer and pathologically determined size of tumor. A total of 297 patients were treated out of the series of 583 breast surgeries.During this five-year survey a continuous increase of breast cancers in Zenica-Doboj Canton was noted.Therehas been an increased incidence of breast cancer in women aged 30-45, the average size of tumor has decreased, and there has been no change in the relationship between the pathohistological types of tumors and tendencies in surgical treatments to use breast conserving surgical methods. The program of early detection of breast cancer or screening of healthy women and search for “small” cancers (screening programs will enable a wider use of breast conserving surgical methods and it requires a more active involvement of the state and society.

    Full Text Available Abstract Background This study was aimed 1 to investigate the predictive value of FDG PET/CT (fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography for histopathologic response and 2 to explore the results of FDG PET/CT by molecular phenotypes of breast cancer patients who received neoadjuvant chemotherapy. Methods Seventy-eight stage II or III breast cancer patients who received neoadjuvant docetaxel/doxorubicin chemotherapy were enrolled in this study. FDG PET/CTs were acquired before chemotherapy and after the first cycle of chemotherapy for evaluating early metabolic response. Results The mean pre- and post-chemotherapy standard uptake value (SUV were 7.5 and 3.9, respectively. The early metabolic response provided by FDG PET/CT after one cycle of neoadjuvant chemotherapy was correlated with the histopathologic response after completion of neoadjuvant chemotherapy (P = 0.002. Sensitivity and negative predictive value were 85.7% and 95.1%, respectively. The estrogen receptor negative phenotype had a higher pre-chemotherapy SUV (8.6 vs. 6.4, P = 0.047 and percent change in SUV (48% vs. 30%, P = 0.038. In triple negative breast cancer (TNBC, the pre-chemotherapy SUV was higher than in non-TNBC (9.8 vs. 6.4, P = 0.008. Conclusions The early metabolic response using FDG PET/CT could have a predictive value for the assessment of histopathologic non-response of stage II/III breast cancer treated with neoadjuvant chemotherapy. Our findings suggest that the initial SUV and the decline in SUV differed based on the molecular phenotype. Trial Registration ClinicalTrials.gov: NCT01396655

    Full Text Available The aim of present research was to prepare novel serum stable long circulating polymeric nanoparticles for curcumin with a modification to the well known and novel nanoparticle albumin bound technology. polyethylene glycol-albumin-curcumin nanoparticles were prepared using serum albumin and poly ethylene glycol using desolvation technique. Nanoparticles were characterized for encapsulation efficiency, particle size and surface morphology. Drug excipient compatibility was determined using fourier transform infrared spectroscopy. Physical state of the drug in the formulations was known by differential scanning colorimetry. In vitrorelease and solubility of the drug from nanoparticles were determined. In vivo Drug release, tissue uptake and kupffer cell uptake was determined with optimized nanoformulation in rats after intravenous administration. Cell viability assay was determined using breast cancer cell line MD-MB-231. Entrapment efficiency for prepared nanoparticle was above 95%. The polyethylene glycol-albumin-curcumin nanoparticles exhibited an interesting release profile with small initial burst followed by slower and controlled release. Solubility of the drug from the formulation was increased. A sustained release of drug from nanoparticles was observed for 35 days in both in vitro and in vivo studies with the optimized formulation. Polyethylene glycol-albumin-curcumin nanoparticles showed lesser liver and kupffer cell uptake as compared to that of curcumin-albumin nanoparticles suggesting the bestowment of stealthness to nanoparticles with pegylation. Also, the antiproliferative activity of polyethylene glycol-albumin-curcumin nanoparticle formulation was more as compared to native curcumin. Polyethylene glycol-albumin-curcumin nanoparticles thus developed can be conveniently used in breast cancer with improved efficacy compared to conventional therapies and as an alternate to nanoparticle albumin bound technology which is used in

    Industrialisation, the proximity of factories to cities, and human work activities have led to a disproportionate use of substances containing heavy metals, such as cadmium (Cd), which may have deleterious effects on human health. Carcinogenic effects of Cd and its relationship with breast cancer, among other tumours, have been reported. 5-Fluorouracil (5-FU) is a fluoropyrimidine anticancer drug used to treat solid tumours of the colon, breast, stomach, liver, and pancreas. The purpose of this work was to study the effects of Cd on cell cycle, apoptosis, and gene and protein expression in MCF-7 breast cancer cells treated with 5-FU. Cd altered the cell cycle profile, and its effects were greater when used either alone or in combination with 5-FU compared with 5-FU alone. Cd significantly suppressed apoptosis of MCF-7 cells pre-treated with 5-FU. Regarding gene and protein expression, bcl2 expression was mainly upregulated by all treatments involving Cd. The expression of caspase 8 and caspase 9 was decreased by most of the treatments and at all times evaluated. C-myc expression was increased by all treatments involving Cd, especially 5-FU plus Cd at the half time of treatment. Cd plus 5-FU decreased cyclin D1 and increased cyclin A1 expression. In conclusion, our results indicate that exposure to Cd blocks the anticancer effects of 5-FU in MCF-7 cells. These results could have important clinical implications in patients treated with 5-FU-based therapies and who are exposed to high levels of Cd.

    The study sought to evaluate the quality of life of women treated surgically for breast cancer at the State Oncology Hospital of Reference in São Luís in the State of Maranhão. The quality of life was assessed by the Functional Assessment of Cancer Therapy-Breast (FACT-B). The variables were expressed as mean and standard deviation, and statistical analysis consisted of the ANOVA or Kruskal Wallis test and the Student t or Mann-Whitney test. The level of significance was α < 5%. For statistical tests Stata 9.0 and BioEstat 5.0 were used. 197 women with mean age of 53.0 ± 11.7 years participated. The mean values of the FACT-B revealed a good quality of life trend, though the emotional domain was most prejudiced and the cancer sub-scale the most favorable. The type of surgery influenced the social, emotional and cancer sub-scale domain. Non-conservative surgery revealed the worst quality of life levels. A statistically significant relationship between duration of surgery and the physical, emotional and functional domains and between duration of surgery and the scores of the FACT-B was detected. Adjuvant treatment influenced all domains of FACT-B. Quality of life was relatively good, but was negatively impacted by non-conservative surgery, the shortest time between surgery and the adjuvant therapies.

Value of AgNOR and MIB-1 index were determined using staining and immunohistochemistry staining method respectively from 25 of microscopic slides of breast cancer tissue patients with surgery, and grouped based on degree of differentiation, 3 slides were good degree (G1, 16 slides were medium degree (G2 and 6 slides were poor degree (between G2 and G3. The result shown that the value of AgNOR and MIB-1 index were tended to increase with the increased differentiation degree. There was a positive correlation between the value of AgNOR and index of MIB-1 in all group of differentiation degree (r = 0.21, there is a negative correlation between AgNOR and MIB-1 on G1 (r =-0,97, positive correlation in G2 (r = 0.36 as well as positive correlation between G2 and G3 (r = 0.33. The positive correlation between AgNOR and MIB-1 were associated to the increased of G1, S and G2 phase in the proliferation cell and an increase of cells undergoing mitosis. The negative correlation were caused by the different cell proportion in G1, S and G2 phase, and undergoing mitotis.

    Trastuzumab-based regimens for the adjuvant treatment of HER2-positive early breast cancer significantly prolonged overall survival (OS) and disease free survival (DFS) in large randomized trials, with sustained benefits at four-year follow-up. We assessed long-term survival estimates and predictors in a large cohort of Italian women with early breast cancer treated with trastuzumab in clinical practice. Through a record linkage between five regional healthcare databases, we identified women treated with trastuzumab for early breast cancer in Lombardy (2006-2009). DFS and OS were estimated using the Kaplan-Meier method, and independent predictors were assessed using proportional hazard models. 2046 women received trastuzumab in early breast cancer adjuvant setting. Overall, the proportion of patients surviving free of disease was 93.9% at one year, 85.8% at 2 years, 79.4% at 3 years, and 75.0% at 4 years. OS estimates were 98.7%, 95.4%, 91.5% and 89.4% at 1, 2, 3 and 4 years, respectively. Significant independent predictors of worse survival outcomes were age breast surgery, combination therapy with paclitaxel, having at least one comorbidity (i.e. diabetes, cardiovascular disease), and a trastuzumab-based regimen lasting less than six months. Long term survival rates of women treated with trastuzumab for early breast cancer in clinical practice were consistent with estimates from clinical trials testing the drug in the adjuvant setting.

    The treatment of breast cancer has made significant improvements during the past ten years. For early breast cancer with a clinically negative axilla sentinel node biopsy has become the preferred approach. For endocrine therapy of postmenopausal patients the selective aromatase inhibitors have become standard in metastatic as well as in early breast cancer. Trastuzumab (Herceptin) plays an important role in the treatment of HER2-positive breast cancer in the metastatic and since 2005 also in the adjuvant setting. When chemotherapy is used to treat metastatic breast cancer drug combinations are superior to monotherapy only in terms of response rates. By contrast, in the adjuvant setting combination drug therapy is the standard. New methods of tissue analysis including expression patterns of mRNA and proteins are promising research strategies to further advance the field.

    Background There is an association between postmenopausal tamoxifen therapy and endometrial pathologies. We investigated the usefulness of diagnostic hysteroscopy and transvaginal ultrasonography (TVS) and estimated whether diagnostic hysteroscopy improves detection of endometrial pathologies in postmenopausal breast cancer patients on tamoxifen. Methods Ninety-seven postmenopausal breast cancer patients who had been taking tamoxifen 20 mg/d for ≥6 months went through TVS, diagnostic hysteroscopy, and endometrial biopsy examinations. The presence of endometrial histopathologic features with abnormal TVS and diagnostic hysteroscopic findings were correlated. Results No endometrial cancer was found in any of the 97 patients. Fifty-three patients (54.6%) developed endometrial polyps as diagnosed histopathologically. Fifty-nine patients (60.8%) tested positive in TVS exams, of whom 43 had polyps, four had hyperplasia, and 12 atrophy. Thirty-eight patients (39.2%) tested negative in TVS exams, of whom 10had polyps, three hyperplasia, and 25 atrophy. TVS exams presented 63.6% specificity, 81.8% sensitivity, 72.9%positive-predictive value, and 73.7% negative-predictive value, whereas the corresponding values of diagnostic hysteroscopy were 100%, 98.1%, 100%, and 97.8% respectively. The correct ratio of hysteroscopy was significantly higher than that of TVS (P=0.000). Conclusions In postmenopausal breast cancer patients treated with tamoxifen, TVS alone is not sufficient for the detection of endometrial pathologies. Additional use of diagnostic hysteroscopy considerably improves the detection of polyps, thus significantly reducing the rate of false-negative findings of endometrial pathologies.

    The aim of this study was to investigate how supplementation of diet of female Sprague-Dawley rats with different doses of conjugated linoleic acids and for a varied period of time influences breast cancer risk, fatty acids profile and lipids peroxidation in chemically induced mammary tumors. Animals were divided into nine groups with different modifications of diet (vegetable oil, 1.0 or 2.0% of CLA) and period of supplementation, which lasted after (A), before (B) and before and after (BA) carcinogenic agent--7,12-dimethylbenz[a]anthracene administration at 50th day of life. Mammary adenocarcinomas occurred in all groups, but CLA supplementation decreased the cancer morbidity. Two percent CLA seems to be excessive because of the coexisting cachexia. Two CLA isomers (9-cis, 11-trans and 10-trans, 12-cis) were detected in tumors but content of rumenic acid was higher. Dietary supplementation significantly influenced some unsaturated fatty acids content (C18:2 n-6 trans, C20:1, C20:5 n-3, C22:2), but the anti- or prooxidant properties of CLA were not confirmed. CLA can inhibit chemically induced mammary tumors development in female rats, but their cytotoxic action seems not to be connected with lipids peroxidation. CLA isomers differ with their incorporation into cancerous tissues and they influence the content of some other fatty acids.

    Full Text Available Background. The purpose of our study is to analyze the association between prescribed Chinese herbal products (CHPs containing Ginseng and the risk of endometrial cancer among tamoxifen (TMX users and to identify any possible interactive effects between Ginseng and TMX with respect to preventing the development of subsequent endometrial cancer in an estrogen-dependent breast cancer population in Taiwan. Methods. All patients newly diagnosed with invasive breast cancer receiving tamoxifen treatment from January 1, 1998, to December 31, 2008, were selected from the National Health Insurance Research Database. The usage, frequency of service, and CHP-Ginseng prescribed across the 30,556 TMX-treated breast cancer (BC survivors were evaluated. Logistic regression was employed to estimate the odds ratios (ORs for the utilization of CHP-Ginseng. Cox’s proportional hazard regression was performed to calculate the hazard ratios (HRs for endometrial cancer associated with Ginseng use among the TMX-treated BC cohort. Results. The HR for the development of endometrial cancer among breast cancer survivors who had ever taken Ginseng after TXM treatment was significantly decreased compared to those who never used CHP. Conclusion. A significant inhibitory relationship between Ginseng consumption and subsequent endometrial cancer less than 2 years after TMX treatment was detected among BC survivors.

    Among breast cancer patients, those diagnosed with the triple-negative breast cancer (TNBC) subtype have the worst prog-nosis. TNBC does not express estrogen receptor-alpha, progesterone receptor, or the HER2 oncogene; therefore, TNBC lacks targets for molecularly-guided therapies. The concept that EGFR oncogene inhibitor drugs could be used as targeted treatment against TNBC has been put forth based on estimates that 30–60% of TNBC express high levels of EGFR. However, results from clinical trials testing EGFR inhibitors, alone or in combination with cytotoxic chemotherapy, did not improve patient outcomes. Results herein offer an explanation as to why EGFR inhibitors failed TNBC patients and support how combining a select antioxidant and an EGFR-specific small molecule kinase inhibitor (SMKI) could be an effective, novel therapeutic strategy. Treatment with CAT-SKL—a re-engineered protein form of the antioxidant enzyme catalase—inhibited cancer stem-like cells (CSCs), and treatment with the EGFR-specific SMKI erlotinib inhibited non-CSCs. Thus, combining the antioxidant CAT-SKL with erlotinib targeted both CSCs and bulk cancer cells in cultures of EGFR-expressing TNBC-derived cells. We also report evidence that the mechanism for CAT-SKL inhibition of CSCs may depend on antioxidant-induced downregulation of a short alternative mRNA splicing variant of the methyl-CpG binding domain 2 gene, isoform MBD2c.

NCD was expressed as the immunoreactive area to cytokeratin over the total original neoplastic area and PI was expressed as the number of immunostained tumoural nuclei with MIB1 MoAb over the total of tumoural nuclei. The intraobserver agreement and that between IA and LMA for both indices were estimated by the common (Kw and the jackknife weighted kappa statistic (K˜w. The extent of agreement of each considered category was also assessed by means of the category‐specific kappa statistics (Kcs. The intraobserver agreement within LMA for NCD and PI and that between IA and LMA for PI were both satisfactory. Upon evaluation of the NCD, the agreement between IA and LMA showed unsatisfactory results, especially when the ratio between the residual tumour cells and the background was critical.

  10. Transcriptome analysis of Wnt3a-treated triple-negative breast cancer cells.

    Directory of Open Access Journals (Sweden)

    Sylvie Maubant

    Full Text Available The canonical Wnt/β-catenin pathway is activated in triple-negative breast cancer (TNBC. The activation of this pathway leads to the expression of specific target genes depending on the cell/tissue context. Here, we analyzed the transcriptome of two different TNBC cell lines to define a comprehensive list of Wnt target genes. The treatment of cells with Wnt3a for 6h up-regulated the expression (fold change > 1.3 of 59 genes in MDA-MB-468 cells and 241 genes in HCC38 cells. Thirty genes were common to both cell lines. Beta-catenin may also be a transcriptional repressor and we found that 18 and 166 genes were down-regulated in response to Wnt3a treatment for 6h in MDA-MB-468 and HCC38 cells, respectively, of which six were common to both cell lines. Only half of the activated and the repressed transcripts have been previously described as Wnt target genes. Therefore, our study reveals 137 novel genes that may be positively regulated by Wnt3a and 104 novel genes that may be negatively regulated by Wnt3a. These genes are involved in the Wnt pathway itself, and also in TGFβ, p53 and Hedgehog pathways. Thorough characterization of these novel potential Wnt target genes may reveal new regulators of the canonical Wnt pathway. The comparison of our list of Wnt target genes with those published in other cellular contexts confirms the notion that Wnt target genes are tissue-, cell line- and treatment-specific. Genes up-regulated in Wnt3a-stimulated cell lines were more strongly expressed in TNBC than in luminal A breast cancer samples. These genes were also overexpressed, but to a much lesser extent, in HER2+ and luminal B tumors. We identified 72 Wnt target genes higher expressed in TNBCs (17 with a fold change >1.3 which may reflect the chronic activation of the canonical Wnt pathway that occurs in TNBC tumors.

    The effects of docetaxel treatment on autonomic cardiac function was studied with 24-h ECG recordings in breast cancer patients pretreated with anthracyclines. Twenty-four women were evaluated before docetaxel treatment and after 3-4 courses of docetaxel 100 mg/m(2). The heart rate, cardiac extrasystoles and heart rate variability (HRV) in both the time and frequency domain were assessed from 24-h ECG recordings. The acute effects of docetaxel were calculated from 1-h recordings immediately prior to, during and after infusion. Long-term effects were evaluated from 24-h recordings performed before treatment and after 3-4 courses of docetaxel. There was no increase in the number of cardiac extrasystoles during docetaxel infusion. The number of ventricular extrasystoles decreased from 14 (23) to 7 (14) during and 5 (10) after the first infusion (p=0.02). The heart rate, HRV and extrasystoles were similar before and after 3-4 courses of docetaxel. The treatment did not abolish circadian variability of the heart rate. Docetaxel did not deteriorate autonomic cardiac function. In conclusion, our findings suggest that docetaxel does not have harmful cumulative effects on autonomic control of the heart and is therefore unlikely to be cardiotoxic.

    Full Text Available Most anticancer drugs are greatly limited by the serious side effects that they cause. Doxorubicin (DOX is an antineoplastic agent, commonly used against breast cancer. However, it may lead to irreversible cardiotoxicity, which could even result in congestive heart failure. In order to avoid these harmful side effects to the patients and to improve the therapeutic efficacy of doxorubicin, we developed DOX-loaded polyethylenimine- (PEI- enhanced human serum albumin (HSA nanoparticles. The formed nanoparticles were ~137 nm in size with a surface zeta potential of ~+15 mV, prepared using 20 μg of PEI added per mg of HSA. Cytotoxicity was not observed with empty PEI-enhanced HSA nanoparticles, formed with low-molecular weight (25 kDa PEI, indicating biocompatibility and safety of the nanoparticle formulation. Under optimized transfection conditions, approximately 80% of cells were transfected with HSA nanoparticles containing tetramethylrhodamine-conjugated bovine serum albumin. Conclusively, PEI-enhanced HSA nanoparticles show potential for developing into an effective carrier for anticancer drugs.

    The purpose of this work was to retrospectively evaluate survival and local control rates of triple-negative breast cancer subtypes classified as five marker negative (5NP) and core basal (CB), respectively, after breast-conserving surgery and intraoperative boost radiotherapy with electrons (IOERT) followed by whole breast irradiation. A total of 71 patients with triple-negative breast cancer were enrolled, who were treated with lumpectomy, axillary lymph node dissection, and IOERT with 9.6 Gy (median D{sub max}) followed by normofractionated whole breast irradiation to median total doses of 54 Gy. Chemotherapy was applied in a neoadjuvant (12 %), adjuvant (75 %), or combinational setting (7 %). After a median follow-up of 97 months (range 4-170 months), 5 in-breast recurrences were detected (7.0 %). For all patients, 8-year actuarial rates for local control, metastases-free survival, disease-specific survival, and overall survival amounted to 89, 75, 80, and 69 %, respectively. All local recurrences occurred in grade 3 (G3) tumors irrespective of their specific immunohistochemical phenotype; thus, the local control rate for grades 1/2 (G1/2) was 100 % for both 5NP and CB, while for G3 it was 88 % for 5NP and 90 % for CB (p = 0.65 and 0.82, respectively, n.s.). For disease-specific survival, only the difference of the best-prognosis group 5-NP/G3 vs. the worst-prognosis cohort CB/G1/2 was statistically significant: 90 % vs. 54 % (p = 0.03). Boost-IOERT provides acceptable long-term in-breast control in triple negative breast cancer. The best subgroup in terms of disease-specific survival was represented by 5NP in combination with tumor grading G3. (orig.)

    Mutation of the key tumour suppressor p53 defines a transition in the progression towards aggressive and metastatic breast cancer (BC) with the poorest outcome. Specifically, the p53 mutation frequency exceeds 50% in triple-negative BC. Key regulators of mutant p53 that facilitate its oncogenic functions are potential therapeutic targets. We report here that the MDM4 protein is frequently abundant in the context of mutant p53 in basal-like BC samples. Importantly, we show that MDM4 plays a critical role in the proliferation of these BC cells. We demonstrate that conditional knockdown (KD) of MDM4 provokes growth inhibition across a range of BC subtypes with mutant p53, including luminal, Her2(+) and triple-negative BCs. In vivo, MDM4 was shown to be crucial for the establishment and progression of tumours. This growth inhibition was mediated, at least in part, by the cell cycle inhibitor p27. Depletion of p27 together with MDM4 KD led to recovery of the proliferative capacity of cells that were growth-inhibited by MDM4 KD alone. Consistently, we identified low levels of p27 expression in basal-like tumours corresponding to high levels of MDM4 and p53. This predicts a signature for a subset of tumours that may be amenable to therapies targeted towards MDM4 and mutant p53. The therapeutic potential of MDM4 as a target in BC with mutant p53 was shown in vitro by use of a small-molecule inhibitor. Overall, our study supports MDM4 as a novel therapeutic target for BC expressing mutant p53. Copyright © 2017 Pathological Society of Great Britain and Ireland. Published by John Wiley & Sons, Ltd.

    Full Text Available PURPOSE: The increased practice of traditional Chinese medicine worldwide has raised concerns regarding herb-drug interactions. We analyzed the usage of Chinese herbal products containing dang-qui and investigated whether dang-qui therapy increases endometrial cancer risk among tamoxifen-treated breast cancer survivors in Taiwan. METHODS: All patients newly diagnosed with invasive breast cancer who received tamoxifen treatment from January 1, 1998, to December 31, 2008 were selected from the National Health Insurance Research Database. The usage, frequency of service and type of Chinese herbal products containing dang-qui prescribed across the 31,970 survivors were evaluated. Logistic regression method was employed to estimate the odds ratios for utilization of Chinese herbal products containing dang-qui. Cox proportional hazard regression was performed to calculate the hazard ratio of endometrial cancer associated with dang-qui use within the cohort. RESULTS: Almost one in two study subjects had used dang-qui. Among 31,938 tamoxifen-treated breast cancer survivors, 157 cases of subsequent endometrial cancer were identified. The hazard ratio for development of endometrial cancer among breast cancer survivors aged 20-79 years who had taken dang-qui after tamoxifen treatment was decreased compared to survivors who had never used dang-qui (HR: 0.61, 95%CI: 0.44-0.84. To minimise potential confounding factors, women with breast cancer in the reproductive age were excluded from further analysis, and the negative relationship between dang-qui consumption and subsequent endometrial cancer among breast cancer survivors aged 55-79 years was still observed, although not significantly (HR: 0.74, 95%CI: 0.46-1.17. CONCLUSIONS: Dang-qui consumption is common among breast cancer survivors aged 20-79 years and seems decrease the risk of subsequent endometrial cancer after less than a cumulative dose of 7,500 mg of tamoxifen treatment.

    Background: With the continuing increase in the use of definitive stereotactic radiosurgery (SRS) for patients with limited brain metastases (BM), clinicians need more specific prognostic tools. We investigated clinical predictors of outcomes in patients with limited breast cancer BM treated with SRS alone. Methods and Materials: We identified 136 patients with breast cancer and 1-3 BM who underwent definitive SRS for 186 BM between 2000 and 2012. The Kaplan-Meier method was used to assess overall survival (OS), regional failure (RF), and local failure (LF). Associations between clinical factors and outcomes were tested using Cox regression. A point scoring system was used to stratify patients based on OS, and the predictive power was tested with concordance probability estimate (CPE). Results: The median OS was 17.6 months. The 12-month RF and LF rates were 45% and 10%, respectively. On multivariate analysis, >1 lesion (hazard ratio [HR] = 1.6, P=.02), triple-negative (TN) disease (HR=2.0, P=.006), and active extracranial disease (ED) (HR=2.7, P<.0001) were significantly associated with worse OS. The point score system was defined using proportional simplification of the multivariate Cox proportional hazards regression function. The median OS for patients with 3.0-4.0 points (n=37), 4.5-5.5 points (n=28), 6.0-6.5 points (n=37), and 8-8.5 points (n=34) were 9.2, 15.6, 25.1, and 45.1 months, respectively (P<.0001, CPE = 0.72). Active ED (HR=2.4, P=.0007) was significantly associated with RF. Higher risk for LF was significantly associated with larger BM size (HR=3.1, P=.0001). Conclusion: Patients with >1 BM, active ED, and TN had the highest risk of death after SRS. Active ED is an important prognostic factor for OS and intracranial control.

    Background. The Swedish Insurance Company for Patient Injuries asked the two authors of this report to identify the Swedish women with cancer of the breast who had been injured by radiotherapy with a hypofractionated schedule. The purpose was to provide a basis on which the Company could decide if indemnification could be given. Material and methods. We define hypo-fractionation as any fraction dose exceeding 2.0 gray (Gy) per day. We set the lower limit for the 'late effect' at 53.0 Gy with 2 Gy/fraction. All departments of radiotherapy in Sweden were asked to identify women who had developed brachial plexus neuropathy (BPN). Their medical records were obtained. The clinical picture of their injuries was recorded, and the absorbed dose was calculated or reconstructed. All doses, no matter in what way they were expressed, were recalculated to 'late effect', presented in EQD2Gy (Equalized Total Dose in 2 Gy/fraction). The latency period from therapy to onset of symptoms was also noted. Results. A variety of treatment techniques was used, fractions ranging in size from 2.5 to 6.0 Gy. Absorbed doses up to a Biologically Equivalent Dose (BED) 146 EQD2Gy in late effects were recorded (6 Gyx13). More than 95% of the injured women had a combination of stiff shoulder, paralysis, pain, oedema and atrophy of the muscles to the arm and/or hand. Latency from end of radiotherapy to onset of symptoms could be as long as 30 years. Discussion. Hypofractionated radiotherapy has injured severely numerous patients. The lesions have become a medico-legal issue in some countries. The life of many of these women has been ruined: physically, mentally, socially and economically. Conclusion. Hypofractionated radiotherapy can cause injuries if the target volume is not exact, or the total dose is not adjusted to a tolerable level as compared to conventional treatments employing 2 Gy/day fractions

    Structural texture measures are used to address the aspect of breast cancer risk assessment in screening mammograms. The current study investigates whether texture properties characterized by local Fractal Dimension (FD) and Lacunarity contribute to asses breast cancer risk. FD represents the complexity while the Lacunarity characterize the gappiness of a fractal. Our cross-sectional case-control study includes mammograms of 50 patients diagnosed with breast cancer in the subsequent 2-4 years and 50 matched controls. The longitudinal double blind placebo controlled HRT study includes 39 placebo and 36 HRT treated volunteers for two years. ROIs with same dimension (250*150 pixels) were created behind the nipple region on these radiographs. Box counting method was used to calculate the fractal dimension (FD) and the Lacunarity. Paired t-test and Pearson correlation coefficient were calculated. It was found that there were no differences between cancer and control group for FD (P=0.8) and Lacunarity (P=0.8) in crosssectional study whereas earlier published heterogeneity examination of radiographs (BC-HER) breast cancer risk score separated groups (p=0.002). In the longitudinal study, FD decreased significantly (Pbreast cancer risk, nor show good sensitivity to HRT.

    Breast cancer is the second most common cancer worldwide and the leading cause of cancer death in women, with incidence rates that continue to rise. The heterogeneity of the disease makes breast cancer exceptionally difficult to treat, particularly for those patients with triple-negative disease. To address the therapeutic complexity of these tumours, new strategies for diagnosis and treatment are urgently required. The ability of lactating and malignant breast cells to uptake and transport iodide has led to the hypothesis that radioiodide therapy could be a potentially viable treatment for many breast cancer patients. Understanding how iodide is transported, and the factors regulating the expression and function of the proteins responsible for iodide transport, is critical for translating this hypothesis into reality. This review covers the three known iodide transporters - the sodium iodide symporter, pendrin and the sodium-coupled monocarboxylate transporter - and their role in iodide transport in breast cells, along with efforts to manipulate them to increase the potential for radioiodide therapy as a treatment for breast cancer.

    Glycometabolism is a distinctive aspect of energy metabolism in breast cancer, and key glycometabolism enzymes/pathways (glycolysis, hexosamine biosynthetic pathway, and pentose phosphate pathway) may directly or indirectly affect the clinical features. In this study, we analyzed the particular correlation between the altered glycometabolism and clinical features of breast cancer to instruct research and clinical treatment. Tissue microarrays containing 189 hollow needle aspiration samples and 295 triple-negative breast cancer tissues were used to test the expression of M2 isoform of pyruvate kinase (PKM2), glutamine-fructose-6-phosphate transaminase 1 (GFPT1), glucose-6-phosphate dehydrogenase (G6PD), and p53 by immunohistochemistry and the intensity of these glycometabolism-related protein was evaluated. Chi-square test, Kaplan-Meier estimates, and Cox proportional hazards model were used to analyze the relationship between the expression of these factors and major clinical features. PKM2, GFPT1, and G6PD affect the pathologic complete response rate of neoadjuvant chemotherapy patients in different ways; pyruvate kinase muscle isozyme 2 (PKM2) and G6PD are closely associated with the molecular subtypes, whereas GFPT1 is correlated with cancer size. All these three factors as well as p53 have impacts on the progression-free survival and overall survival of triple-negative breast cancer patients. Cancer size shows significant association with PKM2 and GFPT1 expression, while the pN stage and grade are associated with PKM2 and G6PD expression. Our study support that clinical characteristics are reflections of specific glycometabolism pathways, so their relationships may shed light on the orientation of research or clinical treatment. The expression of PKM2, GFPT1, and G6PD are hazardous factors for prognosis: high expression of these proteins predict worse progression-free survival and overall survival in triple-negative breast cancer, as well as worse pathologic

    In this article, the American Cancer Society provides an overview of female breast cancer statistics in the United States, including trends in incidence, mortality, survival, and screening. Approximately 230,480 new cases of invasive breast cancer and 39,520 breast cancer deaths are expected to occur among US women in 2011. Breast cancer incidence rates were stable among all racial/ethnic groups from 2004 to 2008. Breast cancer death rates have been declining since the early 1990s for all women except American Indians/Alaska Natives, among whom rates have remained stable. Disparities in breast cancer death rates are evident by state, socioeconomic status, and race/ethnicity. While significant declines in mortality rates were observed for 36 states and the District of Columbia over the past 10 years, rates for 14 states remained level. Analyses by county-level poverty rates showed that the decrease in mortality rates began later and was slower among women residing in poor areas. As a result, the highest breast cancer death rates shifted from the affluent areas to the poor areas in the early 1990s. Screening rates continue to be lower in poor women compared with non-poor women, despite much progress in increasing mammography utilization. In 2008, 51.4% of poor women had undergone a screening mammogram in the past 2 years compared with 72.8% of non-poor women. Encouraging patients aged 40 years and older to have annual mammography and a clinical breast examination is the single most important step that clinicians can take to reduce suffering and death from breast cancer. Clinicians should also ensure that patients at high risk of breast cancer are identified and offered appropriate screening and follow-up. Continued progress in the control of breast cancer will require sustained and increased efforts to provide high-quality screening, diagnosis, and treatment to all segments of the population.

    Purpose: We previously evaluated the risk of breast cancer-related lymphedema (LE) with the addition of regional lymph node irradiation (RLNR) and found an increased risk when RLNR is used. Here we analyze the association of technical radiation therapy (RT) factors in RLNR patients with the risk of LE development. Methods and Materials: From 2005 to 2012, we prospectively screened 1476 women for LE who underwent surgery for breast cancer. Among 1507 breasts treated, 172 received RLNR and had complete technical data for analysis. RLNR was delivered as supraclavicular (SC) irradiation (69% [118 of 172 patients]) or SC plus posterior axillary boost (PAB) (31% [54 of 172]). Bilateral arm volume measurements were performed pre- and postoperatively. Patients' RT plans were analyzed for SC field lateral border (relative to the humeral head), total dose to SC, RT fraction size, beam energy, and type of tangent (normal vs wide). Cox proportional hazards models were used to analyze associated risk factors for LE. Results: Median postoperative follow-up was 29.3 months (range: 4.9-74.1 months). The 2-year cumulative incidence of LE was 22% (95% confidence interval [CI]: 15%-32%) for SC and 20% (95% CI: 11%-37%) for SC plus PAB (SC+PAB). None of the analyzed variables was significantly associated with LE risk (extent of humeral head: P=.74 for <1/3 vs >2/3, P=.41 for 1/3 to 2/3 vs >2/3; P=.40 for fraction size of 1.8 Gy vs 2.0 Gy; P=.57 for beam energy 6 MV vs 10 MV; P=.74 for tangent type wide vs regular; P=.66 for SC vs SC+PAB). Only pretreatment body mass index (hazard ratio [HR]: 1.09; 95% CI: 1.04-1.15, P=.0007) and the use of axillary lymph node dissection (HR: 7.08, 95% CI: 0.98-51.40, P=.05) were associated with risk of subsequent LE development. Conclusions: Of the RT parameters tested, none was associated with an increased risk of LE development. This study underscores the need for future work investigating alternative RLNR risk factors for LE.

    Hierarchical clustering algorithms, such as Pearson's correlation, Euclidean distance, Euclidean distance harmonic,Spearman rank correlation, Kendall's tau, and City-block distance, were used to find the best way to establish theoretical MAPK/Erk signaling pathway on the basis of breast cancer line MCF-7 gene expressions. The algorithm consttucts a hierarchy from top to bottom on the basis of a self-organizing tree. It dynamically finds the number of clusters at each level. It was found that only Euclidean distance harmonic is fit for the analysis of the cascade composed from a RAF1 (c-Raf), a MKNK1, a MAPKK (MEK1/2) to MAPK (Erk) in breast cancer line MCF-7. The result is consistent with the biological experimental MAP/Erk signaling pathway, and the theoretical MAPK/Erk signaling pathway on breast cancer line MCF-7 is set up.

    Full Text Available The American Society for Radiation Oncology (ASTRO consensus statement (CS provides guidelines for patient selection for accelerated partial breast irradiation (APBI following breast conserving surgery. The purpose of this study was to evaluate recurrence rates based on ASTRO CS groupings. A single institution review of 238 early stage breast cancer patients treated with balloon-based APBI via balloon based brachytherapy demonstrated a 4-year actuarial ipsilateral breast tumor recurrence (IBTR rate of 5.1%. There were no significant differences in the 4-year actuarial IBTR rates between the “suitable,” “cautionary,” and “unsuitable” ASTRO categories (0%, 7.2%, and 4.3%, resp., P=0.28. ER negative tumors had higher rates of IBTR than ER positive tumors. The ASTRO groupings are poor predictors of patient outcomes. Further studies evaluating individual clinicopathologic features are needed to determine the safety of APBI in higher risk patients.

    Breast cancer is the most common cancer in women, and the second most common cause of cancer death after lung cancer. Improvements in the outcome of breast cancer mean that more patients are living longer and are, therefore, at risk of developing a second malignancy. The aim of this review is to present the current understanding of the risk of lung cancer arising in patients previously treated for early stage breast cancer. We review data on the effect of treatment factors (ie, surgery type, radiotherapy technique, and adjuvant chemotherapy) and patient factors (ie, age and smoking) on the risk of developing a subsequent lung cancer. The evidence suggests that older radiotherapy techniques were associated with a substantially increased risk of developing lung cancer in the ipsilateral lung, but there is no clear evidence of an increased risk with modern techniques. Smoking is an important risk factor, and increases the risk of lung cancer in those receiving radiotherapy. Adjuvant chemotherapy is not significantly associated with an increased risk. The risk of developing lung cancer increases with time elapsed since treatment, but any effect of age at treatment is unclear.

METHODOLOGY/PRINCIPAL FINDINGS: Post-menopausal breast cancer patients diagnosed no later than 2002, being ER+ as defined by >1% IHC staining and having a frozen tumor sample with >50% tumor content were included. Tumor samples from 108 patients treated with adjuvant Tamoxifen were analyzed for the expression of 59 genes using quantitative-PCR. End-point was clinically verified recurrence to distant organs or ipsilateral breast. Gene profiles were identified using a model building procedure based on conditional logistic regression and leave-one-out cross-validation, followed by a non-parametric bootstrap (1000x re-sampling. The optimal profiles were further examined in 5 previously-reported datasets containing similar patient populations that were either treated with Tamoxifen or left untreated (n = 623. Three gene signatures were identified, the strongest being a 2-gene combination of BCL2-CDKN1A, exhibiting an accuracy of 75% for prediction of outcome. Independent examination using 4 previously-reported microarray datasets of Tamoxifen-treated patient samples (n = 503 confirmed the potential of BCL2-CDKN1A. The predictive value was further determined by comparing the ability of the genes to predict recurrence in an additional, previously-published, cohort consisting of Tamoxifen-treated (n = 58, p = 0.015 and untreated patients (n = 62, p = 0.25. CONCLUSIONS/SIGNIFICANCE: A novel gene expression signature predictive of outcome of Tamoxifen-treated patients was identified. The validation suggests that BCL2-CDKN1A exhibit promising predictive potential.

    After surgery, breast cancer patients are offered adjuvant chemotherapy to avoid cancer cell spread. During chemotherapy process, neutrophils could fall relatively, and side effects could spike to the peak. Therefore, the medical care personnel should prevent the progression of the side effects. This study aimed to examine the effects of Chan-Chuang qi-gong therapy on complete blood counts in breast cancer patients treated with chemotherapy. This study used a quasi-experimental design. The experiment group (n = 32) received a 21-day Chan-Chuang qi-gong therapy, whereas the control group (n = 35) did not. White blood cells, platelet, and hemoglobin were measured on the day before chemotherapy and on days 8, 15, and 22 during chemotherapy. According to this study, there were significant differences in white blood cells (F = 115.76, P qi-gong therapy may decrease leukopenia in breast cancer patients treated with chemotherapy. It is recommended conducting more studies on qi-gong and then introducing it in clinical nursing practice at an appropriate time to promote quality of nursing care and quality of patient life.

    Purpose: To assess the locoregional failure in patients with Stage I-II breast cancer treated with radical mastectomy and to evaluate whether a subset of these patients might be at sufficiently high risk of locoregional recurrence (LRR) to benefit from postmastectomy irradiation (PMRT). Methods and Materials: Stage I-II breast cancer patients (n = 150) treated with radical mastectomy without adjuvant irradiation between 1999 and 2005 were analyzed. The pattern of LRR was reported. Kaplan-Meier analysis was used to calculate rates of LRR, and Cox proportional hazards methods were used to evaluate potential risk factors. Results: Median follow-up was 75 months. Mean patient age was 56 years. One-hundred forty-three (95%) patients received adjuvant systemic therapy: 85 (57%) hormonal therapy alone, 14 (9%) chemotherapy alone, and 44 (29%) both chemotherapy and hormonal therapy. Statistically significant factors associated with increased risk of LRR were premenopausal status (p = 0.004), estrogen receptor negative cancer (p = 0.02), pathologic grade 3 (p = 0.02), and lymphovascular invasion (p = 0.001). T and N stage were not associated with increased risk of regional recurrence. The 5-year LRR rate for patients with zero or one, two, three, and four risk factors was 1%, 10.3%, 24.2%, and 75%, respectively. Conclusions: A subset of patients with early-stage breast cancer is at high risk of LRR, and therefore PMRT might be beneficial.

    Purpose: Ki-67 is a human nuclear protein whose expression is strongly up-regulated in proliferating cells and can be used to determine the growth fraction in clonal cell populations. Although there are some data to suggest that Ki-67 overexpression may be prognostic for endpoints such as survival or postmastectomy recurrence, further elucidation of its prognostic significance is warranted. Specifically after breast conservation therapy (BCT) (defined in this setting as breast-conserving surgery and adjuvant radiation therapy), whether Ki-67 predicts for locoregional recurrence has not been investigated. The purpose of this study was to assess Ki-67 expression in a cohort of early-stage breast cancer patients to determine whether a significant independent association between Ki-67 and locoregional relapse exists. Methods and Materials: Ki-67 staining was conducted on a tissue microarray of 438 patients previously treated with BCT, and expression was analyzed with clinicopathologic features and outcomes from our database. Results: Ki-67 expression was more prevalent in black patients (37% of black patients vs 17% of white patients, P<.01), younger patients (27% of patients aged ≤50 years vs 15% of patients aged >50 years, P<.01), estrogen receptor (ER)–negative tumors (25% of ER-negative tumors vs 17% of ER-positive tumors, P=.04), human epidermal growth factor receptor 2 (HER2)/neu–positive tumors (35% of HER2-positive tumors vs 18% of HER2-negative tumors, P=.01), and larger tumors (26% of T2 tumors vs 16% of T1 tumors, P=.03). On univariate/multivariate analysis, Ki-67 did not predict for overall survival (74.4% vs 72.6%), cause-specific survival (82.9% vs 82.1%), local relapse-free survival (83.6% vs 88.5%), distant metastasis-free survival (76.1% vs 81.4%), recurrence-free survival (65.5% vs 74.6%), and locoregional recurrence-free survival (81.6% vs 84.7%): P>.05 for all. Conclusions: Ki-67 appears to be a surrogate marker for aggressive disease and

  6. Identification of valid reference genes for the normalization of RT-qPCR expression studies in human breast cancer cell lines treated with and without transient transfection.

    Directory of Open Access Journals (Sweden)

    Lin-Lin Liu

    Full Text Available Reverse transcription-quantitative polymerase chain reaction (RT-qPCR is a powerful technique for examining gene expression changes during tumorigenesis. Target gene expression is generally normalized by a stably expressed endogenous reference gene; however, reference gene expression may differ among tissues under various circumstances. Because no valid reference genes have been documented for human breast cancer cell lines containing different cancer subtypes treated with transient transfection, we identified appropriate and reliable reference genes from thirteen candidates in a panel of 10 normal and cancerous human breast cell lines under experimental conditions with/without transfection treatments with two transfection reagents. Reference gene expression stability was calculated using four algorithms (geNorm, NormFinder, BestKeeper and comparative delta Ct, and the recommended comprehensive ranking was provided using geometric means of the ranking values using the RefFinder tool. GeNorm analysis revealed that two reference genes should be sufficient for all cases in this study. A stability analysis suggests that 18S rRNA-ACTB is the best reference gene combination across all cell lines; ACTB-GAPDH is best for basal breast cancer cell lines; and HSPCB-ACTB is best for ER+ breast cancer cells. After transfection, the stability ranking of the reference gene fluctuated, especially with Lipofectamine 2000 transfection reagent in two subtypes of basal and ER+ breast cell lines. Comparisons of relative target gene (HER2 expression revealed different expressional patterns depending on the reference genes used for normalization. We suggest that identifying the most stable and suitable reference genes is critical for studying specific cell lines under certain circumstances.

    Consumption of cruciferous vegetables has been associated with reduced breast cancer risk mechanistically and in population-based studies, although evidence has been inconsistent. This inconsistency may be related to limitations in quantifying and qualifying cruciferous vegetable exposure using standard instruments for dietary assessment (for example, food-frequency questionnaires, FFQs) or due to low levels of intake demonstrated among U.S. population samples. Cruciferous vegetable intake data are presented from a longitudinal study of a high-vegetable dietary intervention to reduce breast cancer recurrence among breast cancer survivors (n=1,156; 536 intervention and 620 comparison group subjects). Intake was assessed using repeat administration of an FFQ and cross-sectional administration of a cruciferous vegetable-specific FFQ (CVFFQ). Mean intake in the intervention group assessed using the standard FFQ was 37.7 g/day at baseline and increased to 57.1 g/day at 12 mo (P=0.0001) and was sustained through 48 mo. Broccoli and cabbage were the most commonly consumed cruciferous vegetables, regardless of the instrument used to assess intake. Differences in intake by group assignment were shown for raw cruciferous vegetables (30.2 g/day vs. 24.6 g/day, assessed using the CVFFQ), suggesting increased exposure to biologically active, cancer-preventive food constituents. These data suggest that this study population will be the first U.S. population sample to provide ample quantity and variety in cruciferous intake to examine whether these vegetables are protective against breast cancer recurrence.

    BACKGROUND: In parous women preeclampsia has been associated with reduced risk of developing breast cancer. Characteristics of births following preeclamptic pregnancies may help understand mechanisms involved in the breast cancer risk reduction inferred by preeclampsia. METHODS: We conducted...... a register-based cohort study of all Danish women giving birth during 1978-2010 (n = 778,701). The association between preeclampsia and breast cancer was evaluated overall and according to birth characteristics by means of incidence rate ratios (IRR) estimated in Poisson regression models. RESULTS: Compared...... with women with non-preeclamptic pregnancies only, women with one or more preeclamptic pregnancies were 19% significantly less likely to develop breast cancer (IRR = 0.81 [95% CI 0.72-0.93]). We found some indication of greater risk reduction in women with term births, one or more previous births...

    We sought to assess whether a close surgical margin (>0 and <2 mm) after breast-conserving therapy (BCT) confers an increased risk of local recurrence (LR) compared with a widely negative margin (≥2 mm). We studied 906 women with early-stage invasive breast cancer treated with BCT between January 1998 and October 2006; 91 % received adjuvant systemic therapy. Margins were coded as: (1) widely negative (n = 729), (2) close (n = 85), or (3) close (n = 84)/positive (n = 8) but having no additional tissue to remove according to the surgeon. Cumulative incidence of LR and distant failure (DF) were calculated using the Kaplan-Meier method. Gray's competing-risk regression assessed the effect of margin status on LR and Cox proportional hazards regression assessed the effect on DF, controlling for biologic subtype, age, and number of positive lymph nodes (LNs). Three hundred seventy-seven patients (41.6 %) underwent surgical re-excision, of which 63.5 % had no residual disease. With a median follow-up of 87.5 months, the 5-year cumulative incidence of LR was 2.5 %. The 5-year cumulative incidence of LR by margin status was 2.3 % (95 % CI 1.4-3.8 %) for widely negative, 0 % for close, and 6.4 % (95 % CI 2.7-14.6 %) for no additional tissue, p = 0.3. On multivariate analysis, margin status was not associated with LR; however, triple-negative subtype (AHR 3.7; 95 % CI 1.6-8.8; p = 0.003) and increasing number of positive LNs (AHR 1.6; 95 % CI 1.1-2.3; p = 0.025) were associated. In an era of routine adjuvant systemic therapy, close surgical margins and maximally resected close/positive margins were not associated with an increased risk of LR compared to widely negative margins. Additional studies are needed to confirm this finding.

    We compare long-term outcomes in patients with node negative early stage breast cancer treated with breast radiotherapy (RT) without the axillary RT field after sentinel lymph node dissection (SLND) or axillary lymph node dissection (ALND). We hypothesize that though tangential RT was delivered to the breast tissue, it at least partially sterilized occult axillary nodal metastases thus providing low nodal failure rates. Between 1995 and 2001, 265 patients with AJCC stages I-II breast cancer were treated with lumpectomy and either SLND (cohort SLND) or SLND and ALND (cohort ALND). Median follow-up was 9.9 years (range 8.3-15.3 years). RT was administered to the whole breast to the median dose of 48.2 Gy (range 46.0-50.4 Gy) plus boost without axillary RT. Chi-square tests were employed in comparing outcomes of two groups for axillary and supraclavicular failure rates, ipsilateral in-breast tumor recurrence (IBTR), distant metastases (DM), and chronic complications. Progression-free survival (PFS) was compared using log-rank test. There were 136/265 (51%) and 129/265 (49%) patients in the SLND and ALND cohorts, respectively. The median number of axillary lymph nodes assessed was 2 (range 1-5) in cohort SLND and 18 (range 7-36) in cohort ALND (P breast RT and SLND alone, experience low AFR or SFR. Our findings, while awaiting mature long-term data from NSABP B-32, support that in patients with negative axillary nodal status such treatment provides excellent long-term cure rates while avoiding morbidities associated with ALND or addition of axillary RT field.

    Full Text Available The development of molecularly targeted drugs has greatly advanced cancer therapy, despite these drugs being associated with some serious problems. Recently, increasing attention has been paid to the anticancer effects of natural products. α-Mangostin, a xanthone isolated from the pericarp of mangosteen fruit, has been shown to induce apoptosis in various cancer cell lines and to exhibit antitumor activity in a mouse mammary cancer model. In this study, we investigated the influence of α-mangostin on apoptosis and cell cycle in the human breast cancer cell line MDA-MB231 (carrying a p53 mutation, and HER2, ER, and PgR negative in order to elucidate its anticancer mechanisms. In α-mangostin-treated cells, induction of mitochondria-mediated apoptosis was observed. On cell-cycle analysis, G1-phase arrest, increased p21cip1 expression and decreases in cyclins, cdc(s, CDKs and PCNA were observed. In conclusion, α-mangostin may be useful as a therapeutic agent for breast cancer carrying a p53 mutation and having HER2- and hormone receptor-negative subtypes.

    The purpose of this study was to measure the peripheral dose which is the absorbed dose in organs located outside the treatment volume such as the thyroid gland and the breast in patients undergoing radiotherapy, utilising the MOSFET dosemeters, as well as to estimate the probability of secondary cancer. The thyroid gland doses, expressed as a percentage of the prescribed dose (%TD), were measured to be 2.0±0.3 %, in whole brain irradiation, 10.0±8.0 % in mediastinum treatment and 8.0±2.0 and 2.0±0.8 % in breast treatment, with and without the supraclavicular irradiation, respectively, with a corresponding risk of 0.2, 2.0, 1.0 and 0.3 %. The dose to the breast was 7.0±2.0 %, in the mediastinum treatment, and 4.0±1.0 and 2.0±0.8 %, in the breast treatment, with and without supraclavicular irradiation, respectively, with a corresponding risk of 4.0, 2.0 and 1.0 %. Although the results indicate that the risk is not negligible, its significance should be considered in conjunction with the existing pathology and age of the patients.

    High income, high socioeconomic status, and affluence increase breast cancer incidence. Socioeconomic status in USA breast cancer studies has been assessed by block-group socioeconomic measures. A block group is a portion of a census tract with boundaries that segregate, as far as possible, socioeconomic groups. In this study, we used US Census income data instead of block groups to gauge socioeconomic status of breast cancer patients in relationship with incidence, prognostic markers, and survival. US state breast cancer incidence and mortality data are from the U.S. Cancer Statistics Working Group, United States Cancer Statistics: 1999-2011. Three-Year-Average Median Household Income by State, 2010 to 2012, is from the U.S. Census Bureau, Current Population Survey, 2011 to 2013 Annual Social and Economic Supplements. County incomes are from the 2005-2009 American Community Survey of the U.S. Census Bureau. The American Community Survey is an ongoing statistical survey that samples a small percentage of the population yearly. Its purpose is to provide communities the information they need to plan investments and services. Breast cancer county incidence and survival data are from the National Cancer Institute's Surveillance, Epidemiology and End Results Program (SEER) data base. We analyzed SEER data from 198 counties in California, Connecticut, Georgia, Hawaii, Iowa, New Mexico, Utah, and Washington. SEER uses the Collaborative Stage (CS) Data Collection System. We have retained the SEER CS variables. There was a significant relationship of income with breast cancer incidence in 50 USA states and the District of Columbia in White women (r = 0.623, p breast cancer. Income was not correlated with 5-year survival of Black race (p = 0.364) or other races (p = 0.624).

In 2008 and 2012 two identical questionnaires were sent to the women aged 18-70 years treated for unilateral primary...... breast cancer in 2005 and 2006. 2293 women (87%) reported on lymphedema in 2008 and 2012. Overall 37% reported lymphedema in 2008 while 31% reported lymphedema in 2012 and severity of symptoms decreased. 50% of women treated with SLNB and reporting lymphedema in 2008 did not report symptoms by 2012...... in contrast to 30% treated with ALND. However, 19% of women treated with ALND and not reporting lymphedema in 2008 had developed lymphedema by 2012. In conclusion lymphedema remains a frequent problem, years after treatment for breast cancer, though, number of women reporting lymphedema and overall severity...

    This is the first textbook of its kind devoted to describing the biological complexities of breast cancer in a way that is relevant to the radiation oncologist. Radiation Oncology has long treated breast cancer as a single biological entity, with all treatment decisions being based on clinical and pathologic risk factors. We are now beginning to understand that biological subtypes of breast cancer may have different risks of recurrence as well as different intrinsic sensitivity to radiotherapy. Multi-gene arrays that have for years been used to predict the risk of distant recurrence and the value of systemic chemotherapy may also have utility in predicting the risk of local recurrence. Additionally, the targeted agents used to treat breast cancer may interact with radiotherapy in ways that can be beneficial or undesirable. All of these emerging issues are extensively discussed in this book, and practical evidence-based treatment recommendations are presented whenever possible.

    Full Text Available Patients with triple receptor-negative breast cancer often develop aggressive metastatic disease, which also might involve the brain. In many cases, systemic and local treatment is needed. It is important to consider the toxicity of chemo- and radiotherapy, especially when newly approved drugs become available. Randomised studies leading to drug approval often exclude patients with newly diagnosed brain metastases. Here we report our initial experience with eribulin mesylate and whole-brain radiotherapy (WBRT in a heavily pretreated patient with multiple brain, lung, and bone metastases from triple receptor-negative breast cancer. Eribulin mesylate was given after 4 previous lines for metastatic disease. Two weeks after the initial dose, that is, during the first cycle, the patient was diagnosed with 5 brain metastases with a maximum size of approximately 4.5 cm. She continued chemotherapy and received concomitant WBRT with 10 fractions of 3 Gy. After 3 cycles of eribulin mesylate, treatment was discontinued because of newly diagnosed liver metastases and progression in the lungs. No unexpected acute toxicity was observed. The only relevant adverse reactions were haematological events after the third cycle (haemoglobin 9.5 g/dL, leukocytes 3.1×109/L. The patient died from respiratory failure 18.5 months from diagnosis of metastatic disease, and 2.7 months from diagnosis of brain metastases. To the best of our knowledge, this is the first report on combined WBRT and eribulin mesylate.

    Full Text Available Breast conserving surgery (BCS with following external beam radiation therapy (EBRT of the conserved breast has become widely accepted in the last decades for the treatment of early invasive breast cancer. The standard technique of EBRT after BCS is to treat the whole breast up to a total dose of 42.5 to 50 Gy. An additional dose is given to treated volume as a boost to a portion of the breast. In the early stage of breast cancer, research has shown that the area requiring radiation treatment to prevent the cancer from local recurrence is the breast tissue that surrounds the area where the initial cancer was removed. Accelerated partial breast irradiation (APBI is an approach that treats only the lumpectomy bed plus a 1-2 cm margin rather than the whole breast and as a result allows accelerated delivery of the radiation dose in four to five days. There has been a growing interest for APBI and various approaches have been developed under phase I-III clinical studies; these include multicatheter interstitial brachytherapy, balloon catheter brachytherapy, conformal external beam radiation therapy (3D-EBRT and intra-operative radiation therapy (IORT. Balloon-based brachytherapy approaches include MammoSite, Axxent electronic brachytherapy, Contura, hybrid brachytherapy devices. Another indication for breast brachytherapy is reirradiation of local recurrence after mastectomy. Published results of brachytherapy are very promising. We discuss the current status, indications, and technical aspects of breast cancer brachytherapy.

    Timely, comprehensive screening for breast cancer is a major, though often overlooked, component of primary health care for women. This article reviews the scientific rationale for screening and outlines the current recommendations of the American Cancer Society and the U.S. Preventive Services Task Force regarding the use of mammography, clinical breast examination (CBE), and breast self-examination (BSE). Nursing interventions to decrease barriers to effective screening are discussed, and an expanded role of nurses in breast cancer screening is proposed.

    Background Parthenolide has been tested for anti-tumor activities,such as anti-proliferation and pro-apoptosis in recent studies.However,little is known about its role in the process of tumor angiogenesis.This study aims to investigate the effects and potential mechanisms of parthenolide on the proliferation,migration and lumen formation capacity of human umbilical vein endothelial cells.Methods Different concentrations of parthenolide were applied to the human breast cancer cell line MDA-MB-231 cells.After 24-hour incubation,the culture supematants were harvested and used to treat human umbilical vein endothelial cells for 24 hours.Then an inverted fluorescence phase contrast microscope was used to evaluate the human umbilical vein endothelial cells.The secretion of vascular endothelial growth factor (VEGF),interleukin (IL)-8 and matrix metalloproteinases (MMP)-9 in the culture supernatant of the MDA-MB-231 cells was then measured with enzyme-linked immunosorbent assay (ELISA) assays.Results Suppression of proliferation,migration,and the lumen formation capacity of human umbilical vein endothelial cells was observed in the presence of the culture supernatants from the breast cancer cell line treated with different concentrations of parthenolide.Parthenolide decreased the levels of the angiogenic factors MMP-9,VEGF,and IL-8secreted by the MDA-MB-231 cells.Conclusions Parthenolide may suppress angiogenesis through decreasing angiogenic factors secreted by breast cancer cells to interfere with the proliferation,migration and lumen-like structure formation of endothelial cells,thereby inhibiting tumor growth.It is a promising potential anti-angiogenic drug.

    The various risk factors for breast cancer have been recognized for many years. A table lists these established breast cancer risk factors together with the approximate magnitude of the increase in risk associated with them. Breast cancer incidence rates increase with age throughout the life span in Western countries, although the rate of increase is greater up to age 50 years than after 50 years. Breast cancer is more common among women in upper rather than lower social classes, among women who never have been married, among women living in urban areas, among women living in the northern US than in the southern US, and among whites than blacks, at least among those over age 50. Women in North American and Northern European countries have the highest risk for breast cancer, women in Southern European and Latin American countries are at intermediate risk, and women in Africa and Asian countries have the lowest risk. Yet, rapid rates of increase in incident rates have been noted in recent years in many Asian, Central European, and some South American countries. The later the age at which a woman has her 1st full-term pregnancy, the higher her risk for breast cancer; the earlier the age at menarche and the later the age at menopause the higher the risk; and among women who have a premenopausal oophorectomy, the earlier the age at which this occurs the lower the risk. Among postmenopausal women, obesity is associated with an increase in risk. Lactation is negatively associated with subsequent breast cancer risk. Some current research is considering potential risk factors that have not been well studied in the past, including alcohol consumption, cigarette smoking, caffeine consumption, exposure to diethylstilbestrol (DES), emotional stress, exposure to electric power, and lack of physical activity. Other areas of current research reviewed here include radiation, mammographic parenchymal patterns, a high-fat diet, use of oral contraceptives (OCs), use of estrogen

    Full Text Available Abstract Background HER2 and TOP2A parameters (gene status, mRNA and protein expression have individually been associated with the outcome of patients treated with anthracyclines. The aim of this study was to comprehensively evaluate the prognostic/predictive significance of the above parameters in early, high-risk breast cancer patients treated with epirubicin-based, dose-dense sequential adjuvant chemotherapy. Methods In a series of 352 breast carcinoma tissues from patients that had been post-operatively treated with epirubicin-CMF with or without paclitaxel, we assessed HER2 and TOP2A gene status (chromogenic in situ hybridization, mRNA expression (quantitative reverse transcription PCR, as well as HER2 and TopoIIa protein expression (immunohistochemistry. Results HER2 and TOP2A amplification did not share the same effects on their downstream molecules, with consistent patterns observed in HER2 mRNA and protein expression according to HER2 amplification (all parameters strongly inter-related, p values Conclusions This study confirms the favorable prognostic value of HER2/TOP2A co-amplification and the adverse prognostic value of high TOP2A mRNA expression extending it to the adjuvant treatment setting in early high-risk breast cancer. The strong adverse prognostic impact of high HER2/TOP2A mRNA co-expression needs further validation in studies designed to evaluate markers predictive for anthracyclines.

    Bevacizumab may improve outcomes of patients with breast cancer, but the absence of an established biomarker hampers patient selection and researchers´ ability to demonstrate a clear survival benefit. Its putative target, circulating VEGF-A, emerged as the main candidate and we sought to identify the relationship between VEGF-A levels and outcomes through systematic review. We searched electronic databases and meeting proceedings for randomized controlled trials (RCTs) comparing the addition of bevacizumab to standard chemotherapy for breast cancer. RCTs were included if outcomes were presented separately according to VEGF-A plasma levels. Random-effects model were applied to calculate the pooled hazard ratios for progression-free survival, event-free survival (EFS), comprising disease recurrence, progression or any-cause death, and overall survival (OS), with respective confidence intervals (95 % CI). High and low VEGF-A levels subgroups followed each trial definition, and results were compared using the interaction test. Heterogeneity was calculated using χ (2) test (I (2)). Three trials enrolled a total of 3748 patients. 1713 patients had baseline VEGF-A levels in plasma available for assessment and were included. One trial added bevacizumab in the adjuvant setting (N = 2591) and two on first-line metastatic disease with taxane-based therapy (N = 1160) There was no interaction between VEGF-A levels and study setting (adjuvant vs. first line therapy). Bevacizumab improved PFS of patients with above median VEGF-A plasma levels (HR 0.56; 95 % CI 0.43-0.73; P cancer. Further studies have to confirm its surrogacy in overall survival and in other scenarios including other anti-angiogenic therapies.

    Purpose: The safety and efficacy of skin-sparing mastectomy (SSM) with immediate reconstruction (IR) in patients with locally advanced breast cancer are unclear. The purpose of this study is to compare the outcomes of women with noninflammatory Stage III SSM with IR vs. non-SSM-treated women who underwent neoadjuvant chemotherapy and adjuvant radiation therapy (XRT). Methods and Materials: Between October 1997 and March 2010, 100 consecutive patients (40 SSM with IR vs. 60 non-SSM) with Stage III breast cancer received anthracycline- and/or taxane-based neoadjuvant chemotherapy, mastectomy, and adjuvant XRT. Clinical stage (SSM with IR vs. for non-SSM) was IIIA (75% vs. 67%), IIIB (8% vs. 18%), and IIIC (8% vs. 8%). Tumors greater than 5 cm were found in 74% vs. 69%; 97% of patients in both groups were clinically node positive; and 8% vs. 18% had T4b disease. Results: The time from initial biopsy to XRT was prolonged for SSM-IR patients (274 vs. 254 days, p = 0.04), and there was a trend toward XRT delay of more than 8 weeks (52% vs. 31%, p = 0.07) after surgery. The rate of complications requiring surgical intervention was higher in the SSM-IR group (37.5% vs. 5%, p < 0.001). The 2-year actuarial locoregional control, breast cancer-specific survival, and overall survival rates for SSM with IR vs. non-SSM were 94.7% vs. 97.4%, 91.5% vs. 86.3%, and 87.4% vs. 84.8%, respectively (p = not significant). Conclusions: In our small study with limited follow-up, SSM with IR prolonged overall cancer treatment time and trended toward delaying XRT but did not impair oncologic outcomes. Complication rates were significantly higher in this group. Longer follow-up is needed.

    2011-03-01

    We report a case of possible retroperitoneal metastasis of breast cancer successfully treated with oral S-1 and cyclophosphamide therapy after docetaxel and cyclophosphamide (TC) therapy. A 57-year-old woman with a history of bilateral breast cancer showed an increase in tumor markers during treatment with oral anastrozole as postoperative adjuvant therapy 4 years after her second cancer surgery. After careful examination, the patient was diagnosed as having multiple bone metastases and her medication was changed to oral letrozole. After 3 months, the patient developed left back pain and was referred to our hospital. CT scanning showed an enhanced mass in the region from the left perirenal and posterior pararenal spaces to the left psoas major muscle and the anterior aspect of the left iliacus muscle, suggesting retroperitoneal metastasis. TC therapy was performed and, as a result, tumor markers decreased and the mass disappeared on CT imaging. After discontinuation of TC therapy, the tumor markers increased again, following which oral S-1 and cyclophosphamide therapy were administered, and the tumor markers decreased. At the time of this writing, the patient is still undergoing therapy, and no recurrence has been observed. We concluded that oral S-1 and cyclophosphamide therapy were useful in the present case and were associated with few adverse effects.

  11. Effect of transfection with PLP2 antisense oligonucleotides on gene expression of cadmium-treated MDA-MB231 breast cancer cells.

    Longo, Alessandra; Librizzi, Mariangela; Luparello, Claudio

    2013-02-01

    Emerging evidence indicates that cadmium (Cd) is able to regulate gene expression, drastically affecting the pattern of transcriptional activity in human normal and pathological cells. We have already shown that exposure of MDA-MB231 breast cancer cells to 5 μM CdCl(2) for 96 h, apart from significantly affecting mitochondrial metabolism, induces modifications of the expression level of genes coding for members of stress response-, mitochondrial respiration-, MAP kinase-, NF-κB-, and apoptosis-related pathways. In the present study, we have expanded the knowledge on the biological effects of Cd-breast cancer cell interactions, indicating PLP2 (proteolipid protein-2) as a novel member of the list of Cd-upregulated genes by MDA-MB231 cancer cells and, through the application of transfection techniques with specific antisense oligonucleotides, we have demonstrated that such over-expression may be an upstream event to some of the changes of gene expression levels already observed in Cd-treated cells, thus unveiling new possible molecular relationship between PLP2 and genes linked to the stress and apoptotic responses.

  12. Progestins and breast cancer.

    Science.gov (United States)

    Pasqualini, Jorge R

    2007-10-01

    Progestins exert their progestational activity by binding to the progesterone receptor (form A, the most active and form B, the less active) and may also interact with other steroid receptors (androgen, glucocorticoid, mineralocorticoid, estrogen). They can have important effects in other tissues besides the endometrium, including the breast, liver, bone and brain. The biological responses of progestins cover a very large domain: lipids, carbohydrates, proteins, water and electrolyte regulation, hemostasis, fibrinolysis, and cardiovascular and immunological systems. At present, more than 200 progestin compounds have been synthesized, but the biological response could be different from one to another depending on their structure, metabolism, receptor affinity, experimental conditions, target tissue or cell line, as well as the biological response considered. There is substantial evidence that mammary cancer tissue contains all the enzymes responsible for the local biosynthesis of estradiol (E(2)) from circulating precursors. Two principal pathways are implicated in the final steps of E(2) formation in breast cancer tissue: the 'aromatase pathway', which transforms androgens into estrogens, and the 'sulfatase pathway', which converts estrone sulfate (E(1)S) into estrone (E(1)) via estrone sulfatase. The final step is the conversion of weak E(1) to the potent biologically active E(2) via reductive 17beta-hydroxysteroid dehydrogenase type 1 activity. It is also well established that steroid sulfotransferases, which convert estrogens into their sulfates, are present in breast cancer tissues. It has been demonstrated that various progestins (e.g. nomegestrol acetate, medrogestone, promegestone) as well as tibolone and their metabolites can block the enzymes involved in E(2) bioformation (sulfatase, 17beta-hydroxysteroid dehydrogenase) in breast cancer cells. These substances can also stimulate the sulfotransferase activity which converts estrogens into the biologically

    Background Screening clinical breast examination (cbe) is controversial; the use of cbe is declining not only as a screening tool, but also as a diagnostic tool. In the present study, we aimed to assess the value of cbe in breast cancer detection in a tertiary care centre for breast diseases. Methods This retrospective study of all breast cancers diagnosed between July 1999 and December 2010 at our centre categorized cases according to the mean of detection (cbe, mammography, or both). A cbe was considered “abnormal” in the presence of a mass, nipple discharge, skin or nipple retraction, edema, erythema, peau d’orange, or ulcers. Results During the study period, a complete dataset was available for 6333 treated primary breast cancers. Cancer types were ductal carcinoma in situ (15.3%), invasive ductal carcinoma (75.7%), invasive lobular carcinoma (9.0%), or others (2.2%). Of the 6333 cancers, 36.5% (n = 2312) were detected by mammography alone, 54.8% (n = 3470) by mammography and cbe, and 8.7% (n = 551) by physician-performed cbe alone (or 5.3% if considering ultrasonography). Invasive tumours diagnosed by cbe alone were more often triple-negative, her2-positive, node-positive, and larger than those diagnosed by mammography alone (p < 0.05). Conclusions A significant number of cancers would have been missed if cbe had not been performed. Compared with cancers detected by mammography alone, those detected by cbe had more aggressive features. Clinical breast examination is a very low-cost test that could improve the detection of breast cancer and could prompt breast ultrasonography in the case of a negative mammogram. PMID:27536182

    In September 2000, a 32-year-old woman presented to our hospital with a right breast mass. In September 2000, she underwent pectoral muscle-preserving mastectomy for the treatment of right breast cancer. Pathologyy results revealed a mucinous carcinoma 27 × 20 × 18 mm in size accompanied by an extensive intraductal component. The tumor was staged as T2 N1M0 stage IIB and found to be estrogen receptor-positive, and 6 cycles of postoperative adjuvant chemotherapy consisting of 5-fluorouracil, epirubicin, and cyclophosphamide were carried out. Goserelin acetate plus tamoxifen was prescribed from April 2001 to March 2005. Since the patient received tamoxifen from April 2005 and eumenorrhea started in June 2006, goserelin acetate plus tamoxifen was started in August 2006. The patient was determined to be 25 weeks pregnant by abdominal ultrasonography in February 2007. This meant that she had been taking goserelin acetate plus tamoxifen for 6 months without realizing she was pregnant. She gave birth to a girl by cesarean section in May 2007. No abnormalities, including anomaly of the genitalia, were seen, and the subsequent growth of the infant was also satisfactory. We here report this case and a brief review of the literature.

  15. Significance of PIK3CA Mutations in Patients with Early Breast Cancer Treated with Adjuvant Chemotherapy: A Hellenic Cooperative Oncology Group (HeCOG Study.

    Full Text Available The PI3K-AKT pathway is frequently activated in breast cancer. PIK3CA mutations are most frequently found in the helical (exon 9 and kinase (exon 20 domains of this protein. The aim of the present study was to examine the role of different types of PIK3CA mutations in combination with molecular biomarkers related to PI3K-AKT signaling in patients with early breast cancer.Tumor tissue samples from 1008 early breast cancer patients treated with adjuvant chemotherapy in two similar randomized trials of HeCOG were examined. Tumors were subtyped with immunohistochemistry (IHC and FISH for ER, PgR, Ki67, HER2 and androgen receptor (AR. PIK3CA mutations were analyzed by Sanger sequencing (exon 20 and qPCR (exon 9 (Sanger/qPCR mutations. In 610 cases, next generation sequencing (NGS PIK3CA mutation data were also available. PIK3CA mutations and PTEN protein expression (IHC were analyzed in luminal tumors (ER and/or PgR positive, molecular apocrine carcinomas (MAC; ER/PgR negative / AR positive and hormone receptor (ER/PgR/AR negative tumors.PIK3CA mutations were detected in 235/1008 tumors (23% with Sanger/qPCR and in 149/610 tumors (24% with NGS. Concordance between the two methods was good with a Kappa coefficient of 0.76 (95% CI 0.69-0.82. Lobular histology, low tumor grade and luminal A tumors were associated with helical domain mutations (PIK3CAhel, while luminal B with kinase domain mutations (PIK3CAkin. The overall incidence of PIK3CA mutations was higher in luminal as compared to MAC and hormone receptor negative tumors (p = 0.004. Disease-free and overall survival did not significantly differ with respect to PIK3CA mutation presence and type. However, a statistically significant interaction between PIK3CA mutation status and PTEN low protein expression with regard to prognosis was identified.The present study did not show any prognostic significance of specific PIK3CA mutations in a large group of predominantly lymph-node positive breast cancer

    Purpose: Postmastectomy radiation therapy (PMRT) has been shown to benefit breast cancer patients with 1 to 3 positive lymph nodes, but it is unclear how modern changes in management have affected the benefits of PMRT. Methods and Materials: We retrospectively analyzed the locoregional recurrence (LRR) rates in 1027 patients with T1,2 breast cancer with 1 to 3 positive lymph nodes treated with mastectomy and adjuvant chemotherapy with or without PMRT during an early era (1978-1997) and a later era (2000-2007). These eras were selected because they represented periods before and after the routine use of sentinel lymph node surgery, taxane chemotherapy, and aromatase inhibitors. Results: 19% of 505 patients treated in the early era and 25% of the 522 patients in the later era received PMRT. Patients who received PMRT had significantly higher-risk disease features. PMRT reduced the rate of LRR in the early era cohort, with 5-year rates of 9.5% without PMRT and 3.4% with PMRT (log-rank P=.028) and 15-year rates 14.5% versus 6.1%, respectively; (Cox regression analysis: adjusted hazard ratio [AHR] 0.37, P=.035). However, PMRT did not appear to benefit patients treated in the later cohort, with 5-year LRR rates of 2.8% without PMRT and 4.2% with PMRT (P=.48; Cox analysis: AHR 1.41, P=.48). The most significant factor predictive of LRR for the patients who did not receive PMRT was the era in which the patient was treated (AHR 0.35 for later era, P<.001). Conclusion: The risk of LRR for patients with T1,2 breast cancer with 1 to 3 positive lymph nodes treated with mastectomy and systemic treatment is highly dependent on the era of treatment. Modern treatment advances and the selected use of PMRT for those with high-risk features have allowed for identification of a cohort at very low risk for LRR without PMRT.

    Lung metastasis is the major cause of death in patients with triple negative breast cancer (TNBC), an aggressive subtype of breast cancer with no effective therapy at present. It has been proposed that dual-targeted therapy, ie, targeting chemotherapeutic agents to both tumor vasculature and cancer cells, may offer some advantages. The present work was aimed to develop a dual-targeted synergistic drug combination nanomedicine for the treatment of lung metastases of TNBC. Thus, Arg-Gly-Asp peptide (RGD)-conjugated, doxorubicin (DOX) and mitomycin C (MMC) co-loaded polymer-lipid hybrid nanoparticles (RGD-DMPLN) were prepared and characterized. The synergism between DOX and MMC and the effect of RGD-DMPLN on cell morphology and cell viability were evaluated in human MDA-MB-231 cells in vitro. The optimal RGD density on nanoparticles (NPs) was identified based on the biodistribution and tumor accumulation of the NPs in a murine lung metastatic model of MDA-MB-231 cells. The microscopic distribution of RGD-conjugated NPs in lung metastases was examined using confocal microscopy. The anticancer efficacy of RGD-DMPLN was investigated in the lung metastatic model. A synergistic ratio of DOX and MMC was found in the MDA-MB-231 human TNBC cells. RGD-DMPLN induced morphological changes and enhanced cytotoxicity in vitro. NPs with a median RGD density showed the highest accumulation in lung metastases by targeting both tumor vasculature and cancer cells. Compared to free drugs, RGD-DMPLN exhibited significantly low toxicity to the host, liver and heart. Compared to non-targeted DMPLN or free drugs, administration of RGD-DMPLN (10 mg/kg, iv) resulted in a 4.7-fold and 31-fold reduction in the burden of lung metastases measured by bioluminescence imaging, a 2.4-fold and 4.0-fold reduction in the lung metastasis area index, and a 35% and 57% longer median survival time, respectively. Dual-targeted RGD-DMPLN, with optimal RGD density, significantly inhibited the progression of

    We recently reported that neoadjuvant 5-FU, epirubicin, and cyclophosphamide (FEC) followed by weekly paclitaxel and/or trastuzumab induced a high pathological complete response (pCR) rate in hormone-negative patients. The present study examined the therapeutic efficacy of neoadjuvant FEC followed by triweekly docetaxel and/or trastuzumab in the treatment of hormone-positive patients. Between February 2012 and December 2013, 16 hormone-positive patients with local breast cancer (luminal A type: six patients; luminal B type: two patients; luminal HER2 type: eight patients) were included in the study. The histological type of the primary cancer was invasive ductal carcinoma in all patients. The cancer stages in the 16 women who received this regimen were stage I in five (31.3%), IIA in four (25.0%), IIB in five (31.3%), IIIB in one (6.3%), and IIIC in one (6.3%). Regarding clinical TNM classification, five patients were T1N0M0, one was T1N1M0, three were T2N0M0, five were T2N1M0, one was T3N2M0, and one was T4N0M0. The pCR was evaluated using resected tissue after neoadjuvant chemotherapy according to the evaluation criteria of the Japanese Breast Cancer Society. Patients were classified into pathologic responders (grade 2: 50.0% of all patients: 2/6 of luminal A type; 6/8 of Luminal HER2 type) and nonresponders (grades 0 and 1: 50.0% of all patients: 4/6 of luminal A type; 2/2 of luminal B type; 2/8 of luminal HER2 type) according to the grade of the tumor. The pCR rate was 0%. Hematologic and nonhematologic toxicity was reversible and manageable. This study demonstrated that neoadjuvant FEC followed by triweekly docetaxel and/or trastuzumab did induce a high pathologic response in luminal HER2 type, but not in luminal A and B types, and did not induce a high pCR rate in the hormone-positive patients.

    Aberrant activation of the hedgehog (Hh) signaling pathway has shown predictive significance for treatment response and prognostic effect for survival in human tumors. However, the associations of the Hh signaling pathway with response to neoadjuvant therapy (NAT) and survival after NAT in breast cancer are unknown. Therefore, we investigated the correlation of pretherapeutic nuclear expression of glioma-associated oncogene homolog 1 (Gli1), a key transcriptional factor of the Hh signaling pathway, with pathological complete response (pCR) and event-free survival (EFS) in HER2-positive breast cancer treated with trastuzumab-based NAT. High nuclear Gli1 expression (OR 0.19; 95 % CI 0.07-0.54; P = 0.002) and positive hormone receptor (HR) status (OR 0.36; 95 % CI 0.14-0.90; P = 0.028) were independent and negative predictors of pCR in multivariate analysis. High nuclear Gli1 expression was significantly associated with lower pCR rates in both HR-positive and HR-negative tumors (P = 0.014 and 0.024, respectively). For survival analyses, multivariate analysis indicated that high nuclear Gli1 expression was the only independent predictor of poorer EFS in both the entire population (hazard ratio 2.97; 95 % CI 1.18-7.44; P = 0.020) and patients with non-pCR (hazard ratio 3.98; 95 % CI 1.35-11.68; P = 0.012). Our study is the first to demonstrate the associations of high nuclear Gli1 expression with resistance to trastuzumab-based NAT and subsequent worse prognosis in HER2-positive disease. These findings suggest that the nuclear Gli1 protein may be a novel target of NAT for HER2-positive breast cancer.

  4. Protein Biomarkers for the Early Detection of Breast Cancer

    Full Text Available Advances in breast cancer control will be greatly aided by early detection so as to diagnose and treat breast cancer in its preinvasive state prior to metastasis. For breast cancer, the second leading cause of cancer-related death among women in the United States, early detection does allow for increased treatment options, including surgical resection, with a corresponding better patient response. Unfortunately, however, many patients' tumors are diagnosed following metastasis, thus making it more difficult to successfully treat the malignancy. There are, at present, no existing validated plasma/serum biomarkers for breast cancer. Only a few biomarkers (such as HER-2/neu, estrogen receptor, and progesterone receptor have utility for diagnosis and prognosis. Thus, there is a great need for new biomarkers for breast cancer. This paper will focus on the identification of new serum protein biomarkers with utility for the early detection of breast cancer.

    Full Text Available Michael Untch1, Christian Jackisch21Interdisciplinary Breast Centre, Helios Klinikum Berlin-Buch, University Charité, Berlin, Germany; 2Department of Gynecology/Obstetrics, Klinikum Offenbach GmbH, Offenbach, GermanyAbstract: The adjuvant treatment of women with endocrine-sensitive early breast cancer has been dominated for the last 40 years by tamoxifen. However, the side-effects associated with this therapy have prompted a search for safer and biochemically more selective endocrine agents and led to the development of the third-generation aromatase inhibitors (AIs anastrozole, letrozole and exemestane. Promising results in advanced disease have paved the way for treating early breast cancer, and AIs are increasingly replacing tamoxifen in the adjuvant setting. Several large, randomized trials with AIs have been completed or are ongoing in women with early-stage breast cancer, documenting the significant impact that these drugs are making on the risk for recurrence of breast cancer. As a result, there is increasing and widespread use of AI therapy for the treatment of early-stage endocrine-responsive breast cancer. This review summarizes the data for exemestane in the adjuvant setting, showing that a switch to exemestane after 2 to 3 years of tamoxifen therapy is associated with a statistically significant survival benefit and is regarded as being sensitive by international and national experts.Keywords: early breast cancer, adjuvant setting, endocrine-sensitive, tamoxifen, aromatase inhibitor, exemestane, switch, IES 31, NSABP B-33, TEAM

    2016-01-01

    Initiation and progression of cancer depend on many factors. Those on the genetic level are often considered crucial. To gain insight into the physical mechanisms of breast cancer, we construct a gene regulatory network (GRN) which reflects both genetic and environmental aspects of breast cancer. The construction of the GRN is based on available experimental data. Three basins of attraction, representing the normal, premalignant and cancer states respectively, were found on the phenotypic landscape. The progression of breast cancer can be seen as switching transitions between different state basins. We quantified the stabilities and kinetic paths of the three state basins to uncover the biological process of breast cancer formation. The gene expression levels at each state were obtained, which can be tested directly in experiments. Furthermore, by performing global sensitivity analysis on the landscape topography, six key genes (HER2, MDM2, TP53, BRCA1, ATM, CDK2) and four regulations (HER2⊣TP53, CDK2⊣BRCA1, ATM→MDM2, TP53→ATM) were identified as being critical for breast cancer. Interestingly, HER2 and MDM2 are the most popular targets for treating breast cancer. BRCA1 and TP53 are the most important oncogene of breast cancer and tumor suppressor gene, respectively. This further validates the feasibility of our model and the reliability of our prediction results. The regulation ATM→MDM2 has been extensive studied on DNA damage but not on breast cancer. We notice the importance of ATM→MDM2 on breast cancer. Previous studies of breast cancer have often focused on individual genes and the anti-cancer drugs are mainly used to target the individual genes. Our results show that the network-based strategy is more effective on treating breast cancer. The landscape approach serves as a new strategy for analyzing breast cancer on both the genetic and epigenetic levels and can help on designing network based medicine for breast cancer.

  15. Beyond Axillary Lymph Node Metastasis, BMI and Menopausal Status Are Prognostic Determinants for Triple-Negative Breast Cancer Treated by Neoadjuvant Chemotherapy.

    Directory of Open Access Journals (Sweden)

    Hélène Bonsang-Kitzis

    Full Text Available Triple-negative breast cancers (TNBC are a specific subtype of breast cancers with a particularly poor prognosis. However, it is a very heterogeneous subgroup in terms of clinical behavior and sensitivity to systemic treatments. Thus, the identification of risk factors specifically associated with those tumors still represents a major challenge. A therapeutic strategy increasingly used for TNBC patients is neoadjuvant chemotherapy (NAC. Only a subset of patients achieves a pathologic complete response (pCR after NAC and have a better outcome than patients with residual disease.The aim of this study is to identify clinical factors associated with the metastatic-free survival in TNBC patients who received NAC.We analyzed 326 cT1-3N1-3M0 patients with ductal infiltrating TNBC treated by NAC. The survival analysis was performed using a Cox proportional hazard model to determine clinical features associated with prognosis on the whole TNBC dataset. In addition, we built a recursive partitioning tree in order to identify additional clinical features associated with prognosis in specific subgroups of TNBC patients.We identified the lymph node involvement after NAC as the only clinical feature significantly associated with a poor prognosis using a Cox multivariate model (HR = 3.89 [2.42-6.25], p<0.0001. Using our recursive partitioning tree, we were able to distinguish 5 subgroups of TNBC patients with different prognosis. For patients without lymph node involvement after NAC, obesity was significantly associated with a poor prognosis (HR = 2.64 [1.28-5.55]. As for patients with lymph node involvement after NAC, the pre-menopausal status in grade III tumors was associated with poor prognosis (HR = 9.68 [5.71-18.31].This study demonstrates that axillary lymph node status after NAC is the major prognostic factor for triple-negative breast cancers. Moreover, we identified body mass index and menopausal status as two other promising prognostic factors in

Recently, molecular breast cancer classification has advanced significantly with the availability of genomic profiling technologies. Proteomic technologies have also advanced from traditional protein assays including enzyme-linked immunosorbent assay, immunoblotting and immunohistochemistry to more comprehensive approaches including mass spectrometry and reverse phase protein lysate arrays (RPPA). The purpose of this manuscript is to review the current protein markers that influence breast cancer prediction and prognosis and to focus on novel advances in proteomic classification of breast cancer.

  20. Estrogens and breast cancer

    Full Text Available In this review, we summarize the epidemiologic evidence for the associations of oral contraceptives and postmenopausal hormones with risk of breast cancer. We also describe the biologic plausibility of these relationships. Overall, there appears to be little, if any, increase in risk with oral contraceptive use in general, even among users for 10 or more years. However, compared to never users, current oral contraceptive users appear to have a modest elevation in risk that subsides within about 10 years after cessation of use. For postmenopausal hormones, the weight of the evidence suggests little or no increase in risk among users of short duration, or for use in the past. However, current longer term use is associated with an increased risk of breast cancer that increases with duration. This increase in risk is large enough, and well enough supported, to be considered along with the other risks and benefits of postmenopausal hormone therapy.

  1. Interleukin-19 in Breast Cancer

    Full Text Available Inflammatory cytokines within the tumor microenvironment are linked to progression in breast cancer. Interleukin- (IL- 19, part of the IL-10 family, contributes to a range of diseases and disorders, such as asthma, endotoxic shock, uremia, psoriasis, and rheumatoid arthritis. IL-19 is expressed in several types of tumor cells, especially in squamous cell carcinoma of the skin, tongue, esophagus, and lung and invasive duct carcinoma of the breast. In breast cancer, IL-19 expression is correlated with increased mitotic figures, advanced tumor stage, higher metastasis, and poor survival. The mechanisms of IL-19 in breast cancer have recently been explored both in vitro and in vivo. IL-19 has an autocrine effect in breast cancer cells. It directly promotes proliferation and migration and indirectly provides a microenvironment for tumor progression, which suggests that IL-19 is a prognostic marker in breast cancer and that antagonizing IL-19 may have therapeutic potential.

    Full Text Available Breast cancer is the most frequently diagnosed neoplastic disease in women around menopause often leading to a significant reduction of these women’s ability to function normally in everyday life. The increased breast cancer incidence observed in epidemiological studies in a group of women actively participating in social and professional life implicates the necessity of conducting multidirectional studies in order to identify risk factors associated with the occurrence of this type of neoplasm. Taking the possibility of influencing the neoplastic transformation process in individuals as a criterion, all the risk factors initiating the process can be divided into two groups. The first group would include inherent factors such as age, sex, race, genetic makeup promoting familial occurrence of the neoplastic disease or the occurrence of benign proliferative lesions of the mammary gland. They all constitute independent parameters and do not undergo simple modification in the course of an individual’s life. The second group would include extrinsic factors conditioned by lifestyle, diet or long-term medical intervention such as using oral hormonal contraceptives or hormonal replacement therapy and their influence on the neoplastic process may be modified to a certain degree. Identification of modifiable factors may contribute to development of prevention strategies decreasing breast cancer incidence.

    Purpose: To examine locoregional and distant recurrence (LRR and DR) in women with pT1-2N0 breast cancer according to approximated subtype and clinicopathologic characteristics. Methods and Materials: Two independent datasets were pooled and analyzed. The study participants were 1994 patients with pT1-2N0M0 breast cancer, treated with mastectomy without radiation therapy. The patients were classified into 1 of 5 subtypes: luminal A (ER+ or PR+/HER 2−/grade 1-2, n=1202); luminal B (ER+ or PR+/HER 2−/grade 3, n=294); luminal HER 2 (ER+ or PR+/HER 2+, n=221); HER 2 (ER−/PR−/HER 2+, n=105) and triple-negative breast cancer (TNBC) (ER−/PR−/HER 2−, n=172). Results: The median follow-up time was 4.3 years. The 5-year Kaplan-Meier (KM) LRR were 1.8% in luminal A, 3.1% in luminal B, 1.7% in luminal HER 2, 1.9% in HER 2, and 1.9% in TNBC cohorts (P=.81). The 5-year KM DR was highest among women with TNBC: 1.8% in luminal A, 5.0% in luminal B, 2.4% in luminal HER 2, 1.1% in HER 2, and 9.6% in TNBC cohorts (P<.001). Among 172 women with TNBC, the 5-year KM LRR were 1.3% with clear margins versus 12.5% with close or positive margins (P=.04). On multivariable analysis, factors that conferred higher LRR risk were tumors >2 cm, lobular histology, and close/positive surgical margins. Conclusions: The 5-year risk of LRR in our pT1-2N0 cohort treated with mastectomy was generally low, with no significant differences observed between approximated subtypes. Among the subtypes, TNBC conferred the highest risk of DR and an elevated risk of LRR in the presence of positive or close margins. Our data suggest that although subtype alone cannot be used as the sole criterion to offer postmastectomy radiation therapy, it may reasonably be considered in conjunction with other clinicopathologic factors including tumor size, histology, and margin status. Larger cohorts and longer follow-up times are needed to define which women with node-negative disease have high postmastectomy LRR

    A 63-year-old male presented with a bilateral breast carcinoma. Both axillae showed metastases. The patient was treated with a bilateral modified breast amputation. Study of the literature shows that synchronous bilateral breast cancer in males is uncommon. Even in a male with changing breast tissue a carcinoma has to be considered. In male breast cancer, adherence to diagnostic and treatment guidelines for female breast cancer is generally advocated. In males, hormonal causes have to be excluded.

    Asian women, including Korean, have a relatively higher incidence of dense breast tissue, compared with western women. Dense breast tissue has a lower sensitivity for the detection of breast cancer and a higher relative risk for breast cancer, compared with fatty breast tissue. Thus, there were limitations in the mammographic screening for women with dense breast tissue, and many studies for the supplemental screening methods. This review included appropriate screening methods for Korean women with dense breasts. We also reviewed the application and limitation of supplemental screening methods, including breast ultrasound, digital breast tomosynthesis, and breast magnetic resonance imaging; and furthermore investigated the guidelines, as well as the study results.

    Circadian clocks respond to environmental time cues to coordinate 24-hour oscillations in almost every tissue of the body. In the breast, circadian clocks regulate the rhythmic expression of numerous genes. Disrupted expression of circadian genes can alter breast biology and may promote cancer. Here we overview circadian mechanisms, and the connection between the molecular clock and breast biology. We describe how disruption of circadian genes contributes to cancer via multiple mechanisms, an...

    2001-10-01

    The aim of the study was to evaluate the importance of young age with regard to local control in a prospective cohort of 1085 women with pathological T1 tumours treated with breast conservative treatment (BCT). Patients were divided into two age groups: 40 years or younger, 7.8%, and older than 40 years, 92.2%. With a median follow-up of 71 months, the local recurrence rate was 10.6% in women 40 years (P=0.0046). A separate analysis showed a significantly decreased LRFS for young women with a positive family history, 75.4% versus 98.4% 5-year LRFS for older women. A worse LRFS for young women with a negative lymph node status was also observed, respectively 84% versus 98% 5-year LRFS (both P<0.001). In a multivariate analysis, taking into account the pre-treatment and treatment factors, age < or =40 years, was the only significant predictor of a decreased LRFS. Thus, young age is an important factor in relation to local control. In a subset analysis, this significant adverse effect of young age on outcome appears to be limited to the node-negative patients and those with a positive family history. To date, there is no evidence that young women with pT1 breast cancer, treated by mastectomy have an improved outcome when compared with those treated with conservative surgery and radiotherapy. Taking into account results from a subset analysis suggests that giving systemic therapy to a subgroup of women who are < or =40 years, node-negative and/or have a positive family history might give a better local control.

    2016-01-01

    Background. Early discontinuation of aromatase inhibitors (AIs) is common and leads to poor outcomes but is challenging to predict. In the Exemestane and Letrozole Pharmacogenetics trial, a high rate of early discontinuation due to intolerance was observed. We hypothesized that early changes in patient-reported outcomes (PROs) predict AI discontinuation and that biochemical factors are associated with changes in PROs. Patients and Methods. Postmenopausal women with early-stage breast cancer enrolled in a prospective randomized trial of exemestane versus letrozole completed questionnaires at baseline and serially over 24 months to assess overall quality of life (EuroQOL Visual Analog Scale [VAS]); mood; and multiple symptoms, including a musculoskeletal symptom cluster. A joint mixed-effects/survival model was used to estimate the effect of the change in PROs on AI discontinuation. Associations between biochemical factors and change in PROs were examined. Results. A total of 490 patients were analyzed. Worsening of EuroQOL VAS and the musculoskeletal cluster were associated with the highest risk for early discontinuation (hazard ratio [HR], 2.77 [95% confidence interval (CI), 2.72–2.81; p = .015]; HR, 4.39 [95% CI, 2.40–8.02; p < .0001], respectively). Pharmacokinetics and estrogen metabolism were not consistently associated with change in PRO measures. No clinically significant differences in any PRO between AIs were observed. Conclusion. Changes in PROs early during AI therapy were associated with treatment discontinuation. Identification of these changes could be used to target interventions in patients at high risk for early discontinuation. Implications for Practice: Early changes in patient-reported outcomes (PROs) can predict nonpersistence to aromatase inhibitor therapy. If used in clinical practice, PROs might identify women at highest risk for early discontinuation and allow for interventions to improve tolerance before significant toxicities develop

    This manifesto was prepared by a European Breast Cancer (EBC) Council working group and launched at the European Breast Cancer Conference in Glasgow on 20 March 2014. It sets out optimal technical and organisational requirements for a breast cancer pathology service, in the light of concerns about variability and lack of patient-centred focus. It is not a guideline about how pathology services should be performed. It is a call for all in the cancer community--pathologists, oncologists, patient advocates, health administrators and policymakers--to check that services are available that serve the needs of patients in a high quality, timely way.

    2015-07-01

    Conclusion: Our study demonstrated that cell viability of MCF-7 cells was decreased after treatment with VPA, probably through a reduction of telomerase activity and an increase in Bax/bcl-2 ratio. Therefore, it could be concluded that VPA is a potent anti-cancer agent for breast cancer cells through inhibition of telomerase activity and induction of apoptosis.

  4. Predictive and prognostic impact of TP53 mutations and MDM2 promoter genotype in primary breast cancer patients treated with epirubicin or paclitaxel.

    Directory of Open Access Journals (Sweden)

    Ranjan Chrisanthar

    Full Text Available BACKGROUND: TP53 mutations have been associated with resistance to anthracyclines but not to taxanes in breast cancer patients. The MDM2 promoter single nucleotide polymorphism (SNP T309G increases MDM2 activity and may reduce wild-type p53 protein activity. Here, we explored the predictive and prognostic value of TP53 and CHEK2 mutation status together with MDM2 SNP309 genotype in stage III breast cancer patients receiving paclitaxel or epirubicin monotherapy. EXPERIMENTAL DESIGN: Each patient was randomly assigned to treatment with epirubicin 90 mg/m(2 (n = 109 or paclitaxel 200 mg/m(2 (n = 114 every 3rd week as monotherapy for 4-6 cycles. Patients obtaining a suboptimal response on first-line treatment requiring further chemotherapy received the opposite regimen. Time from last patient inclusion to follow-up censoring was 69 months. Each patient had snap-frozen tumor tissue specimens collected prior to commencing chemotherapy. PRINCIPAL FINDINGS: While TP53 and CHEK2 mutations predicted resistance to epirubicin, MDM2 status did not. Neither TP53/CHEK2 mutations nor MDM2 status was associated with paclitaxel response. Remarkably, TP53 mutations (p = 0.007 but also MDM2 309TG/GG genotype status (p = 0.012 were associated with a poor disease-specific survival among patients having paclitaxel but not patients having epirubicin first-line. The effect of MDM2 status was observed among individuals harbouring wild-type TP53 (p = 0.039 but not among individuals with TP53 mutated tumors (p>0.5. CONCLUSION: TP53 and CHEK2 mutations were associated with lack of response to epirubicin monotherapy. In contrast, TP53 mutations and MDM2 309G allele status conferred poor disease-specific survival among patients treated with primary paclitaxel but not epirubicin monotherapy.

  5. Aluminium, antiperspirants and breast cancer.

    Science.gov (United States)

    Darbre, P D

    2005-09-01

    Aluminium salts are used as the active antiperspirant agent in underarm cosmetics, but the effects of widespread, long term and increasing use remain unknown, especially in relation to the breast, which is a local area of application. Clinical studies showing a disproportionately high incidence of breast cancer in the upper outer quadrant of the breast together with reports of genomic instability in outer quadrants of the breast provide supporting evidence for a role for locally applied cosmetic chemicals in the development of breast cancer. Aluminium is known to have a genotoxic profile, capable of causing both DNA alterations and epigenetic effects, and this would be consistent with a potential role in breast cancer if such effects occurred in breast cells. Oestrogen is a well established influence in breast cancer and its action, dependent on intracellular receptors which function as ligand-activated zinc finger transcription factors, suggests one possible point of interference from aluminium. Results reported here demonstrate that aluminium in the form of aluminium chloride or aluminium chlorhydrate can interfere with the function of oestrogen receptors of MCF7 human breast cancer cells both in terms of ligand binding and in terms of oestrogen-regulated reporter gene expression. This adds aluminium to the increasing list of metals capable of interfering with oestrogen action and termed metalloestrogens. Further studies are now needed to identify the molecular basis of this action, the longer term effects of aluminium exposure and whether aluminium can cause aberrations to other signalling pathways in breast cells. Given the wide exposure of the human population to antiperspirants, it will be important to establish dermal absorption in the local area of the breast and whether long term low level absorption could play a role in the increasing incidence of breast cancer.

    We evaluate here the redox status in pre- and post-menopausal healthy women and in women with breast cancer in order to understand the consequences of the hormonal alterations of menopause for the oxidative stress status, its modifications with breast cancer and the influence of neoadjuvant chemotherapy (NC). To that, serum oxidative stress parameters (total antioxidant capacity, lipid peroxidation and protein oxidation), non-enzyme antioxidant defenses (total glutathione, uric acid and bilirubin) and enzyme antioxidant defenses (superoxide dismutase, catalase and glutathione peroxidase activities) were measured in healthy women and in women with breast cancer divided according to their menopausal status and that received or not NC. Circulating estradiol, progesterone, FSH and LH were also analyzed. We found that menopause itself modifies the redox status of healthy women, being most of these differences also reflected in women with breast cancer. However, several changes occur as a consequence of the disease. Furthermore, NC increases oxidative damage, decreases antioxidant defenses and eliminates the differences found in menopause. We conclude that the normal redox balance is disrupted by breast cancer but is also affected by the hormonal status promoted by menopause. In fact, NC nullifies the differences found between pre- and postmenopausal women in several antioxidant defense systems.

  9. Epigenetics and Breast Cancers

    Full Text Available Several of the active compounds in foods, poisons, drugs, and industrial chemicals may, by epigenetic mechanisms, increase or decrease the risk of breast cancers. Enzymes that are involved in DNA methylation and histone modifications have been shown to be altered in several types of breast and other cancers resulting in abnormal patterns of methylation and/or acetylation. Hypermethylation at the CpG islands found in estrogen response element (ERE promoters occurs in conjunction with ligand-bonded alpha subunit estrogen receptor (Erα dimers wherein the ligand ERα dimer complex acts as a transcription factor and binds to the ERE promoter. Ligands could be 17-β-estradiol (E2, phytoestrogens, heterocyclic amines, and many other identified food additives and heavy metals. The dimer recruits DNA methyltransferases which catalyze the transfer of methyl groups from S-adenosyl-L-methionine (SAM to 5′-cytosine on CpG islands. Other enzymes are recruited to the region by ligand-ERα dimers which activate DNA demethylases to act simultaneously to increase gene expression of protooncogenes and growth-promoting genes. Ligand-ERα dimers also recruit histone acetyltransferase to the ERE promoter region. Histone demethylases such as JMJD2B and histone methyltransferases are enzymes which demethylate lysine residues on histones H3 and/or H4. This makes the chromatin accessible for transcription factors and enzymes.

    Full Text Available Both diet and nutrition have been studied in relationship with breast cancer risk, as the great variation among different countries in breast cancer incidence could possibly be explained through the inflammatory and immune response, as well as antioxidant intake, among others.To date, no clear association with diet beyond overweight and weight gain has been found, except for alcohol consumption. Nonetheless, the small number of studies done in middle to low income countries where variability of food intake is wider,is beginning to show interesting results.Tanto la dieta como la nutrición han sido estudiadas en relación con el riesgo de cáncer de mama, dada la gran variación de incidencia de cáncer entre países, y la posibilidad de explicarla a través de la respuesta inflamatoria o inmune, así como ingesta de antioxidantes,entre otros.Hasta la fecha, ninguna asociación clara con la dieta ha sido encontrada, excepto para el consumo de alcohol, más allá del sobrepeso y del incremento de peso. Sin embargo, los estudios que se están realizando en países de mediano a bajo nivel de ingresos, con mayor variabilidad de ingesta de alimentos, comienzan a mostrar resultados interesantes.

  13. Behavioral Symptoms after Breast Cancer Treatment: A Biobehavioral Approach

    2015-08-01

    Full Text Available Being diagnosed and treated for breast cancer is emotionally and physically challenging. Breast cancer is the most commonly diagnosed cancer and the second leading cause of death for women in the United States. Accordingly, women with a breast cancer history are the largest group of female cancer survivors. Psychological stress substantially augments adverse autonomic, endocrine, and immune discharge, including enhanced production of proinflammatory cytokines. Importantly, inflammation is a key biological mechanism underlying the symptom cluster of pain, depression, fatigue, and sleep disturbances; there is also good evidence that inflammation contributes to breast cancer recurrence. Stress may exert direct effects on psychological and physiological risk processes. In this review, we take a biobehavioral approach to understanding predictors and mechanisms underlying somatic symptoms in breast cancer survivors.

    Thirty-six evaluable patients with advanced breast cancer who had failed prior CMF therapy [15 (42%) as adjuvant treatment and 21 (58%) for advanced disease] were treated with a combination of vincristine, doxorubicin, and mitomycin (VAM). There was one CR and 10 PR, giving a response rate of 31% (P, 95% confidence interval, 15%-47%). Response was not significantly related to age, performance status, disease-free interval, dominant site of disease, number of sites of disease, or estrogen receptor status. The median duration of response was 5 months for patients attaining CR or PR and 4.6 months for patients with stable disease. The median survival for patients with CR or PR of 7.9 months was not better than for those with stable disease (8.0 months), but both groups had significantly longer survival than those with initial progression. Patients who received VAM after failing adjuvant CMF had a 53% response rate (8 of 15), as against a 14% response rate (3 of 21) in those failing CMF for advanced disease (P less than 0.05). In spite of this difference, the survival distributions for these two groups were not significantly different. Myelosuppression was moderate and no cardiac toxicity was seen. The addition of mitomycin to vincristine and doxorubicin in previously treated patients does not appear to improve the results obtained with vincristine and doxorubicin alone.

    Purpose: Comparison of the amount of irradiated lung tissue volume and mass in patients with breast cancer treated with an optimized tangential-field technique with and without a deep inspiration breath-hold (DIBH) technique and its impact on the normal-tissue complication probability (NTCP). Material and Methods: Computed tomography datasets of 60 patients in normal breathing (NB) and subsequently in DIBH were compared. With a Real-Time Position Management Respiratory Gating System (RPM), anteroposterior movement of the chest wall was monitored and a lower and upper threshold were defined. Ipsilateral lung and a restricted tangential region of the lung were delineated and the mean and maximum doses calculated. Irradiated lung tissue mass was computed based on density values. NTCP for lung was calculated using a modified Lyman-Kutcher-Burman (LKB) model. Results: Mean dose to the ipsilateral lung in DIBH versus NB was significantly reduced by 15%. Mean lung mass calculation in the restricted area receiving {<=} 20 Gy (M{sub 20}) was reduced by 17% in DIBH but associated with an increase in volume. NTCP showed an improvement in DIBH of 20%. The correlation of individual breathing amplitude with NTCP proved to be independent. Conclusion: The delineation of a restricted area provides the lung mass calculation in patients treated with tangential fields. DIBH reduces ipsilateral lung dose by inflation so that less tissue remains in the irradiated region and its efficiency is supported by a decrease of NTCP. (orig.)

    Women who have been treated for breast cancer are at risk for second breast cancers, such as ipsilateral recurrence or contralateral metachronous breast cancer. As the number of breast cancer survivors increases, interest in patient management and surveillance after treatment has also increased. However, post-treatment surveillance programs for patients with breast cancer have not been firmly established. In this review, we focus on the imaging modalities that have been used in post-treatment surveillance for patients with breast cancer, such as mammography, ultrasonography, magnetic resonance imaging, and positron emission tomography, the effectiveness of each modality for detecting recurrence, and how they can be applied to manage patients.

    Response of cancer cells to chemotherapy-induced DNA damage is regulated by the ATM-Chk2 and ATR-Chk1 pathways. We investigated the association between phosphorylated H2AX (γ-H2AX), a marker of DNA double-strand breaks that trigger the ATM-Chk2 cascade, and phosphorylated Chk1 (pChk1), with pathological complete response (pCR) in triple-negative breast cancer (TNBC) patients treated with neoadjuvant chemotherapy. γ-H2AX and pChk1 were retrospectively assessed by immunohistochemistry in a series of pretreatment biopsies related to 66 patients. In fifty-three tumors hormone receptor status was negative in both the diagnostic biopsies and residual cancers, whereas in 13 cases there was a slight hormone receptor expression that changed after chemotherapy. Internal validation was carried out. In the entire cohort elevated levels of γ-H2AX, but not pChk1, were associated with reduced pCR rate (p = 0.009). The association tested significant in both uni- and multivariate logistic regression models (OR 4.51, 95% CI: 1.39-14.66, p = 0.012, and OR 5.07, 95% CI: 1.28-20.09, p = 0.021, respectively). Internal validation supported the predictive value of the model. The predictive ability of γ-H2AX was further confirmed in the multivariate model after exclusion of tumors that underwent changes in hormone receptor status during chemotherapy (OR 7.07, 95% CI: 1.39-36.02, p = 0.018). Finally, in residual diseases a significant decrease of γ-H2AX levels was observed (p predict pCR in TNBC and deserves larger, prospective studies.

    Increasing interest in the role of lipids in cancer cell proliferation or resistance to drug therapies has motivated the need to develop better tools for cellular lipid analysis. Quantification of lipids in cells is typically done by destructive chromatography protocols that do not provide spatial information on lipid distribution and prevent dynamic live cell studies. Methods that allow the analysis of lipid content in live cells is therefore of great importance for research. Using Raman micro-spectroscopy we investigated whether the female hormone medroxyprogesterone acetate (MPA) and the synthetic androgen R1881 affect the lipid expression in breast (T47D) and prostate (LNCaP) cancer cells. Differences were noted in the spectral regions at 830-1800 cm-1 and 2800-3000 cm-1 when comparing different drug treatments. Significant changes were noticed for saturated (1063 - 1125 cm-1, 1295 cm-1 and 1439 cm-1), unsaturated (1262 cm-1 and 1656 cm-1, and 1720 - 1748 cm-1) chemical bonds, suggesting that the composition of the lipid droplets was changed by the hormone treatments. Also, significant differences were observed in the high frequency regions of lipids and proteins at 2851 cm-1 and around 2890 cm-1. Principal component analysis with Linear Discriminant Analysis (PCA-LDA) of the Raman spectra was able to differentiate between cancer cells that were treated with MPA, R1881 or vehicle (P < 0.05). Future work includes analysis to determine exact lipid composition and concentrations as well as development of clinical techniques to characterize differences in patient tumor lipid profiles to determine response to drug treatment and prognosis.

    Full Text Available Erica Jackson, Hatem SolimanUniversity of South Florida/Moffitt Cancer Center and Research Institute, Tampa, FL, USAAbstract: Breast cancer vaccines are being developed to stimulate adaptive antitumor immune responses in patients. These vaccines have the potential to treat breast cancer with minimal side effects and toxicity. However, many obstacles still need to be overcome to fully realize the vaccines' clinical benefit. A review of the literature was conducted to assess the use of vaccines in targeting transformed cells. Four vaccines currently under study were discussed, each summarizing the different vaccine platforms used to introduce target antigen to the patient's immune system. The advantages and disadvantages of each method were discussed, although no one method was found to be superior. Additional issues addressed included overcoming tumor-induced immunosuppression, immune evasion of transformed cells, the use of vaccines in combination therapy, and the challenges of using these vaccines in various clinical settings. Vaccines may be most effective in patients with minimal residual disease, as opposed to using them in the metastatic setting. Also, specific clinical trial design considerations for the use of vaccines in cancer patients, such as time-to-failure end points, were discussed. Understanding these various elements will be important to the translation of breast cancer vaccine therapy into routine clinical practice.Keywords: breast cancer, vaccine, immunotherapy, immune tolerance, peptide vaccine, dendritic cell vaccine

    The relation between breast cancer and selected nonestrogenic drugs was evaluated in the Group Health Cooperative of Puget Sound, Seattle, Washington, a prepaid health care organization with computerized information on diagnoses and outpatient drug use. No important positive associations with breast cancer were found in a follow-up study of 302 women aged 35-74 years. These women were newly diagnosed with breast cancer in 1977-1980 and were studied in relation to exposure in the six months prior to diagnosis to one or more of the following drugs: diazepam, digitalis glycosides, medroxyprogesterone acetate, methyldopa, metronidazole, phenothiazines, tricyclic antidepressants, thiazides, thyroid/levothyroxine sodium, or spironolactone. A modest association between recent reserpine use and breast cancer was present (risk ratio = 1.7, 90% confidence interval 0.9-3.3).

    Full Text Available Abstract Skeletal muscle wasting is a major component of cachectic states found in a variety of disease settings, including cancer. As increasing caloric intake often provides little benefit in combating muscle loss in cachectic patients, a major research focus has been to develop strategies stimulating muscle anabolic pathways - in an attempt to fight the catabolic pathways induced during cachexia. Two recent papers have reported the beneficial effects of blocking the myostatin/activin signalling pathway in mouse models of cancer cachexia. We discuss the implications of their findings both with respect to the role that this signalling pathway may play in the aetiology of cachexia and with respect to the prospects for targeting this pathway as a therapeutic strategy in patients with cachexia.

    Metalloestrogens are metals that activate the estrogen receptor in the absence of estradiol. The metalloestrogens fall into two subclasses: metal/metalloid anions and bivalent cationic metals. The metal/metalloid anions include compounds such as arsenite, nitrite, selenite, and vanadate while the bivalent cations include metals such as cadmium, calcium, cobalt, copper, nickel, chromium, lead, mercury, and tin. The best studied metalloestrogen is cadmium. It is a heavy metal and a prevalent environmental contaminant with no known physiological function. This review addresses our current understanding of the mechanism by which cadmium and the bivalent cationic metals activate estrogen receptor-α. The review also summarizes the in vitro and in vivo evidence that cadmium functions as an estrogen and the potential role of cadmium in breast cancer.

    Purpose We sought to determine whether the combination of ixabepilone plus capecitabine improved overall survival (OS) compared with capecitabine alone in patients with metastatic breast cancer (MBC) previously treated with anthracyclines and taxanes. Patients and Methods A total of 1,221 patients with MBC previously treated with anthracycline and taxanes were randomly assigned to ixabepilone (40 mg/m2 intravenously on day 1) plus capecitabine (2,000 mg/m2 orally on days 1 through 14) or capecitabine alone (2,500 mg/m2 on the same schedule) given every 21 days. The trial was powered to detect a 20% reduction in the hazard ratio (HR) for death. Results There was no significant difference in OS between the combination and capecitabine monotherapy arm, the primary end point (median, 16.4 v 15.6 months; HR = 0.9; 95% CI, 078 to 1.03; P = .1162). The arms were well balanced with the exception of a higher prevalence of impaired performance status (Karnofsky performance status 70% to 80%) in the combination arm (32% v 25%). In a secondary Cox regression analysis adjusted for performance status and other prognostic factors, OS was improved for the combination (HR = 0.85; 95% CI, 0.75 to 0.98; P = .0231). In 79% of patients with measurable disease, the combination significantly improved progression-free survival (PFS; median, 6.2 v 4.2 months; HR = 0.79; P = .0005) and response rate (43% v 29%; P < .0001). Grade 3 to 4 neuropathy occurred in 24% treated with the combination, but was reversible. Conclusion This study confirmed a previous trial demonstrating improved PFS and response for the ixabepilone-capecitabine combination compared with capecitabine alone, although this did not result in improved survival.

    The non-classical human leukocyte antigen G (HLA-G) molecule and its soluble forms exert multiple immune suppressive regulatory functions in malignancy and in stem cells contributing to immune escape mechanisms. HLA-G can be secreted as free soluble HLA-G molecules or via extracellular vesicles (EVs). Here we evaluated these soluble HLA-G forms as prognostic marker for prediction of the clinical outcome of neoadjuvant chemotherapy (NACT) treated breast cancer (BC) patients. Plasma samples of BC patients procured before (n=142) and after (n=154) NACT were quantified for total soluble HLA-G (sHLA-Gtot) and HLA-G levels in ExoQuick™ derived EV fractions (sHLA-GEV) by ELISA. The corresponding increments were specified as free sHLA-G (sHLA-Gfree). Total and free sHLA-G were significantly increased in NACT treated BC patients compared to healthy controls (n=16). High sHLA-Gfree levels were exclusively associated to estrogen receptor expression before NACT. Importantly, high sHLA-GEV levels before NACT were related to disease progression and the detection of stem cell-like circulating tumor cells, but high sHLA-Gfree levels indicated an improved clinical outcome. Thus, this study demonstrates for the first time that the different sHLA-G subcomponents represent dissimilar qualitative prognostic impacts on the clinical outcome of NACT treated BC patients, whereas the total sHLA-G levels without separating into subcomponents are not related to clinical outcome.

    A cohort of 3,090 women with clinical diagnosis of benign breast disease (BBD) was studied. Of these, 1,216 were treated with radiation therapy during 1925-54 (median age 40 years). The mean dose to the breasts was 5.8 Gy (range 0-50 Gy). Among other organs the lung received the highest scattered dose (0.75 Gy; range 0.004-8.98 Gy) and the rectum the lowest (0.008 Gy; range 0-0.06 Gy). A pooled analysis of eight breast cancer incidence cohorts was done, including: tumour registry data on breast cancer incidence among women in the Life Span Study cohort of atomic bomb survivors; women in Massachusetts who received repeated chest fluoroscopic during lung collapse treatment for tuberculosis; women who received x-ray therapy for acute post-partum mastitis; women who were irradiated in infancy for enlarged thymus glands ; two Swedish cohorts of women who received radiation treatments during infancy for skin hemangioma; and the BBD cohort. Together the cohorts included almost 78,000 women (-35,000 were exposed), around 1.8 million woman-years and 1500 cases. The breast cancer incidence rate as a function of breast dose was analysed using linear-quadratic Poisson regression models. Cell-killing effects and other modifying effects were incorporated through additional log-linear terms. Additive (EAR) and multiplicative (ERR) models were compared in estimating the age-at-exposure patterns and time related excess. The carcinogenic risks associated with radiation in mammographic mass screening is evaluated. Assessment was made in terms of breast cancer mortality and years of life. Effects were related to rates not influenced by a mammographic mass screening program and based on a hypothetical cohort of 100,000 40-year old women with no history of breast cancer being followed to 100 years of age. Two radiation risk assumptions were compared. The dose-response relationship is linear with little support in data for an upward curvature at low to medium doses. The competing effect

    Full Text Available Breast cancer is the most frequent malignancy and second leading cause of cancer-related deaths among women. Despite advances in genetic and biochemical analyses, the incidence of breast cancer and its associated mortality remain very high. About 60 - 70% of breast cancers are Estrogen Receptor alpha (ER-α positive and are dependent on estrogen for growth. Selective estrogen receptor modulators (SERMs have therefore provided an effective targeted therapy to treat ER-α positive breast cancer patients. Unfortunately, development of resistance to endocrine therapy is frequent and leads to cancer recurrence. Our understanding of molecular mechanisms involved in the development of ER-α positive tumors and their resistance to ER antagonists is currently limited due to lack of experimental models of ER-α positive breast cancer. In most mouse models of breast cancer, the tumors that form are typically ER-negative and independent of estrogen for their growth. However, in recent years more attention has been given to develop mouse models that develop different subtypes of breast cancers, including ER-positive tumors. In this review, we discuss the currently available mouse models that develop ER-α positive mammary tumors and their potential use to elucidate the molecular mechanisms of ER-α positive breast cancer development and endocrine resistance.

    Full Text Available Vitamin D (VD reduces the risk of breast cancer and improves disease prognoses. Potential VD analogs are being developed as therapeutic agents for breast cancer treatments. The large-conductance Ca2+-activated K+ channel KCa1.1 regulates intracellular Ca2+ signaling pathways and is associated with high grade tumors and poor prognoses. In the present study, we examined the effects of treatments with VD receptor (VDR agonists on the expression and activity of KCa1.1 in human breast cancer MDA-MB-453 cells using real-time PCR, Western blotting, flow cytometry, and voltage-sensitive dye imaging. Treatments with VDR agonists for 72 h markedly decreased the expression levels of KCa1.1 transcripts and proteins in MDA-MB-453 cells, resulting in the significant inhibition of depolarization responses induced by paxilline, a specific KCa1.1 blocker. The specific proteasome inhibitor MG132 suppressed VDR agonist-induced decreases in KCa1.1 protein expression. These results suggest that KCa1.1 is a new downstream target of VDR signaling and the down-regulation of KCa1.1 through the transcriptional repression of KCa1.1 and enhancement of KCa1.1 protein degradation contribute, at least partly, to the antiproliferative effects of VDR agonists in breast cancer cells.

    To retrospectively investigate whether background parenchymal enhancement (BPE) of the contralateral breast on preoperative dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is associated with therapeutic outcomes following neoadjuvant chemotherapy (NAC) in unilateral invasive breast cancer. The institutional review board approved this study, and informed consent was waived. Between 2009 and 2011, 93 women with unilateral invasive breast cancer (43 premenopausal women who performed pre-NAC MRI between days 7 and 20 of the menstrual cycle and 50 postmenopausal women) underwent NAC with pre- and post-NAC DCE-MRI before surgery. MRI features (BPE [minimal, mild, moderate, marked] of the contralateral breast, lesion size and number, lesion kinetics, and changes in lesion size) and clinicopathologic features were analyzed. Patients were grouped according to BPE category (high [moderate or marked] or low [minimal or mild]). Cox regression modeling was used to determine associations between MRI features and recurrence-free survival (RFS) after controlling for clinicopathologic variables. The mean follow-up period was 48.2 months. Twenty-three recurrences occurred (2 ipsilateral breasts, 6 regional, and 15 distant). On multivariate analysis, high BPE on pre-NAC MRI (hazard ratio [HR] = 3.851, P = 0.006) and triple-negative cancer (HR = 3.192, P = 0.002) were independent factors associated with worse RFS. A greater reduction of lesion size on post-NAC MRI (HR = 0.984, P = 0.021) was associated with better RFS. High BPE on pre-NAC MRI is significantly associated with worse RFS in an NAC setting. This study suggests that BPE on pre-NAC DCE-MRI may have potential as a predictor of long-term outcomes in breast cancer patients who undergo NAC.

    This systematic review summarizes research on the use of progestin and breast cancer risk. Although mainly used for contraception, progestin can help treat menstrual disorders, and benign breast, uterine, and ovarian diseases. Breast cancer is the leading site of new, non-skin, cancers in females in the United States, and possible factors that may modulate breast cancer risk need to be identified. ProQuest (Ann Arbor, MI) and PubMed-Medline (US National Library of Medicine, Bethesda MD, USA) databases were used to search for epidemiologic studies from 2000 to 2015 that examined the association between progestin and breast cancer. Search terms included epidemiologic studies + progesterone or progestin or progestogen or contraceptive or contraceptive agents + breast cancer or breast neoplasms. A total of six studies were included in the review. Five of the six studies reported no association between progestin-only formulations (including norethindrone oral contraceptives, depot medroxyprogesterone acetate, injectable, levonorgestrel system users, implantable and intrauterine devices) and breast cancer risk. Duration of use was examined in a few studies with heterogeneous results. Unlike studies of other oral contraceptives, studies indicate that progestin-only formulations do not increase the risk of breast cancer, although the literature is hampered by small sample sizes. Future research is needed to corroborate these findings, as further understanding of synthetic progesterone may initiate new prescription practices or guidelines for women's health.

    Full Text Available : Carcinoma breast is the commonest malignancy of females all over the world and second leading cause of death due to cancer among females. The incidence of breast carcinoma in India is on the rise. The prognosis of tumors depends upon the size of the tumour at presentation, histological type, grade, marginal clearance and lymph node status. The prevalence of hormone receptor-positive breast cancer in Asian countries has been found to be lower than the western world where more than 50% tumours express hormone receptors. The study aims at determining the incidence and prevalence of hormonal receptors and Her-2-neu in various subtypes of breast carcinoma and the distribution of expression among the epidemiological subgroups of patients of different age groups, parity, reproductive status etc. All cases of breast cancers attending the oncology OPD in a tertiary care hospital in South India during a 2 year period (2012-2013 were taken up for our study. The criteria of selection of patients included availability of histopathological diagnosis, hormone receptor studies, Her-2-neu expression status and follow up till the study period. Breast carcinomas tend to occur more frequently in older and post-menopausal females. However the incidence of breast carcinoma in females below 40 is on the rise. Greater awareness regarding self-examination of breast, screening tests like mammogram and ultrasound and fine needle aspiration cytology should be advocated for an early diagnosis and better prognosis. Risk factors of developing carcinoma breast include obesity, diabetes, estrogen exposure and nulliparity. Most tumors belong to Grade III, probably because patients present to the hospital a late stage of cancer. The prevalence of estrogen receptor positivity is 43.3%, progesterone receptor is 30% and Her 2 neu over expression is 56.6%. Hormone receptor status depends on size, histological type and grade of the tumour. In our study we found that there is no

There is therefore a necessity for an adjuvant that maintains the quality of life (QOL and immune function of cancer patients receiving anthracycline-based chemotherapies.Patients and methods: The present study investigated the effectiveness of the concomitant use of Lentinula edodes mycelia extract (LEM, an oral immunomodulator, with FEC75 (5-fluorouracil + epirubicin + cyclophosphamide therapy on host QOL and immune function in breast cancer patients with nodal metastases. Ten breast cancer patients with nodal metastases receiving surgery were enrolled in this study. Treatment with 5-fluorouracil (500 mg/m2, epirubicin (75 mg/m2, and cyclophosphamide (500 mg/m2 was performed every 21 days for two courses, and LEM (1800 mg/day by mouth was administered during the second course.Results: In the first course, hematological toxicity was observed and host QOL and immune function were exacerbated. In the second course, however, the number of white blood cells and lymphocytes did not decrease and host QOL was maintained. Furthermore, the cytotoxic activities of natural killer (NK and lymphokine-activated killer cells and the proportion of activated NK and NK T-cells in lymphocytes were maintained in the second course.Conclusion: It has been suggested that the concomitant use of LEM with FEC75 therapy can maintain host QOL and immune function, and offer important implications for an application of LEM as a useful oral adjuvant to anthracycline-based chemotherapies

    Full Text Available Hyperthermia is potentially an effective method for the treatment of cancer, especially breast cancer tumors. One of the most attractive attributes of hyperthermia is the possibility of providing therapeutic benefit noninvasively, minimizing side effects. To be effective, a hyperthermia treatment must selectively heat the cancerous tissue, elevating the temperature in the tumor without exposing healthy tissue to excessive temperature elevations. In this paper, a suggested simple model of Annular Phased Array (APA using eight half wavelength linear dipoles is presented. New software (COMSOL MULTIPHYSICS is used to calculate the temperature distribution inside a model of a three layered breast (skin, breast tissue, and tumor. In addition, the effect of changing the amplitude and phases of the array elements on the temperature distributions and the conditions on the values of the phases are demonstrated in order to achieve the objective of hyperthermia for breast tumor treatment.

    In prognostic studies for breast cancer patients treated with neoadjuvant chemotherapy (NAC), the ordinary Cox proportional-hazards (PH) model has been often used to identify prognostic factors for disease-free survival (DFS). This model assumes that all patients eventually experience relapse or death. However, a subset of NAC-treated breast cancer patients never experience these events during long-term follow-up (>10 years) and may be considered clinically "cured." Clinical factors associated with cure have not been studied adequately. Because the ordinary Cox PH model cannot be used to identify such clinical factors, we used the Cox PH cure model, a recently developed statistical method. This model includes both a logistic regression component for the cure rate and a Cox regression component for the hazard for uncured patients. The purpose of this study was to identify the clinical factors associated with cure and the variables associated with the time to recurrence or death in NAC-treated breast cancer patients without a pathologic complete response, by using the Cox PH cure model. We found that hormone receptor status, clinical response, human epidermal growth factor receptor 2 status, histological grade, and the number of lymph node metastases were associated with cure.

    Cognitive changes in older women receiving chemotherapy are poorly understood. We examined self-reported cognitive function for older women who received adjuvant chemotherapy on Cancer and Leukemia Group B (CALGB) 49907. CALGB 49907 randomized 633 women aged ≥65 with stage I-III breast cancer to standard adjuvant chemotherapy (cyclophosphamide-methotrexate-5-fluorouracil or doxorubicin-cyclophosphamide) versus capecitabine. We examined self-reported cognitive function in 297 women (CALGB 361002) who enrolled on the quality of life substudy and had no gross impairment on cognitive screening. Women were evaluated using an 18-item instrument at six time points (baseline through 24 months). At each time point for each patient, we calculated a cognitive function score (CFS) defined as the mean response of items 1-18 and defined impairment as a score >1.5 standard deviations above the overall average baseline score. Differences in scores by patient characteristics were evaluated using a Kruskal-Wallis test. A linear mixed-effects model was used to assess CFSs by treatment over time. Among 297 women, the median age was 71.5 (range 65-85) and 73 % had performance status of 0. Baseline depression and fatigue were reported in 6 and 14 % of patients, respectively. The average CFS at baseline was 2.08 (corresponding to "normal ability"), and baseline cognitive function did not differ by treatment regimen (p = 0.350). Over 24 months, women reported minimal changes at each time point and insignificant differences by treatment arm were observed. In a healthy group of older women, chemotherapy was not associated with longitudinal changes in self-reported cognitive function.

    Representing an enormous health care and socioeconomic challenge, breast cancer is the second most common cancer in the world and the second most common cause of cancer-related death. Although many of the challenges associated with preventing, treating, and ultimately curing breast cancer are addressable in the laboratory, successful translation of groundbreaking research to clinical populations remains an important barrier. Particularly when compared with research on other types of solid tumors, breast cancer research is hampered by a lack of tractable in vivo model systems that accurately recapitulate the relevant clinical features of the disease. A primary objective of this article was to provide a generalizable overview of the types of in vivo model systems, with an emphasis primarily on murine models, that are widely deployed in preclinical breast cancer research. Major opportunities to advance precision cancer medicine facilitated by molecular imaging of preclinical breast cancer models are discussed.

    Full Text Available Breast cancer remains a major public health problem, being the second cause of cancer death in women. There is a marked tendency to restrict the extension of surgical gesture, which directly leads to two different attitudes: radical surgery and conservative surgery, to which, at least in our country, there are still some delays. Prospective and retrospective studies have shown that, in 20 years, conservative and radical therapy had about the same rate of survival and disease-free interval, at least for stage I and II breast cancer, the only real counterargument against conservative surgery being that, in principle, the higher rate of recurrence local constraint can be solved by postoperative radiotherapy. Finally, the survival rate is the main parameter of evaluation, assessing the effectiveness of the treatment in breast cancer, and in all its other forms.

    Patients must be followed up closely after primary therapy for invasive breast cancer so that locoregional recurrences can be detected early. Once a recurrence has been detected, a thorough evaluation is indicated to exclude distant metastatic disease. If none is found, the patient may be a candidate for aggressive surgical intervention to render the patient disease-free. If distant disease is found, certain sites, such as the CNS or long bones, may warrant aggressive therapy because failure to treat these sites may lead to excessive morbidity. In most situations, patients with distant disease are treated with palliative measures. In selected instances, however, patients with metastatic breast cancer are candidates for aggressive intervention, including pulmonary or liver resection or high-dose chemotherapy in combination with autologous bone marrow transplantation, to rid the patient of the disease.

    Compared with other fields of medicine, there is hardly an area that has seen such fast development as the world of breast cancer. Indeed, the way we treat breast cancer has changed fundamentally over the past decades. Breast imaging has always been an integral part of this change, and it undergoes constant adjustment to new ways of thinking. This relates not only to the technical tools we use for diagnosing breast cancer but also to the way diagnostic information is used to guide treatment. There is a constant change of concepts for and attitudes toward breast cancer, and a constant flux of new ideas, new treatment approaches, and new insights into the molecular and biological behavior of this disease. Clinical breast radiologists and even more so, clinician scientists, interested in breast imaging need to keep abreast with this rapidly changing world. Diagnostic or treatment approaches that are considered useful today may be abandoned tomorrow. Approaches that seem irrelevant or far too extravagant today may prove clinically useful and adequate next year. Radiologists must constantly question what they do, and align their clinical aims and research objectives with the changing needs of contemporary breast oncology. Moreover, knowledge about the past helps better understand present debates and controversies. Accordingly, in this article, we provide an overview on the evolution of breast imaging and breast cancer treatment, describe current areas of research, and offer an outlook regarding the years to come.

    The purpose of this study was to examine the effect of a whole body exercise programme and dragon boat training on changes in arm volume in breast cancer survivors. A total of 16 female breast cancer survivors with no clinical history of lymphoedema volunteered. The 20-week exercise programme consisted of resistance and aerobic exercise with the addition of dragon boat training at week 8. Arm circumference at two sites (CIRC10, CIRC15), arm volume (VOL), and upper body strength (1-RM) were measured at baseline (T1), week 8 (T2), and week 20 (T3). All statistical tests were two-sided (alpha exercise programme and dragon boat training resulted in a significant increase in upper extremity volume over time. However, the changes were consistent for both arms and the significant gain in upper body muscular strength likely accounted for the increase in arm volume.

    Full Text Available Abstract Background Male breast cancer is a rare but aggressive and devastating disease. This disease presents at a later stage and in a more advanced fashion than its female counterpart. The immunophenotype also appears to be distinct when compared to female breast cancer. Angiogenesis plays a permissive role in the development of a solid tumor and provides an avenue for nutrient exchange and waste removal. Recent scrutiny of angiogenesis in female breast cancer has shown it to be of significant prognostic value. It was hypothesized that this holds true in invasive ductal carcinoma of the male breast. In the context of male breast cancer, we investigated the relationship of survival and other clinico-pathological variables to the microvascular density of the tumor tissue. Methods Seventy-five cases of primary male breast cancer were identified using the records of the Saskatchewan Cancer Agency over a period of 26 years. Forty-seven cases of invasive ductal carcinoma of the male breast had formalin-fixed paraffin-embedded tissue blocks that were suitable for this study. All cases were reviewed. Immunohistochemical staining was performed for the angiogenic markers (cluster designations 31 (CD31, 34 (CD34 and 105 (CD105, von Willebrand factor (VWF, and vascular endothelial growth factor (VEGF. Microvascular density (MVD was determined using average, centre, and highest microvessel counts (AMC, CMC, and HMC, respectively. Statistical analyses compared differences in the distribution of survival times and times to relapse between levels of MVD, tumor size, node status and age at diagnosis. In addition, MVD values were compared within each marker, between each marker, and were also compared to clinico-pathological data. Results Advanced age and tumor size were related to shorter survival times. There were no statistically significant differences in distributions of survival times and times to relapse between levels of MVD variables. There was no

    Bone is the preferred site of metastasis for breast cancer, and presence of skeletal lesions is associated with significant morbidity and poor prognosis. Skeletal-related effects such as pain, pathologic fractures, spinal compression, and hypercalcemia are frequent consequences of skeletal lesions of breast cancer that have debilitating effects on the patients' quality of life. In addition to direct cancer effects on the skeleton, therapies commonly used to treat patients with breast cancer such as chemotherapy and aromatase inhibitors (AI) result in cancer therapy-induced bone loss (CTIBL) which is associated with increased risk of skeletal complications such as fractures. Bisphosphonates are a class of antiresorptive drugs that are now firmly established as the cornerstone of the management of skeletal-related events due to breast cancer. Other novel bone-targeting agents such as the anti-receptor activator of NF-κB ligand (RANKL) monoclonal antibody denosumab are also showing promising activity in the treatment of bone metastasis secondary to breast cancer. Moreover, recent provocative evidence suggests that bisphosphonates might also exhibit antitumor activity via direct and indirect mechanisms. The goal of this review is to summarize the pathophysiology of osteolytic bone lesions secondary to breast cancer, provide clinical evidence of currently available bone-targeted drugs in the treatment of bone metastasis and CTIBL, and explore the antitumor activity of current bone-targeted agents in patients with breast cancer.

    Secretory carcinoma of the breast is a rare tumor initially described in children but occurring equally in adult population. This unusual breast cancer subtype has a generally favorable prognosis, although several cases have been described in adults with increased aggressiveness and a risk of metastases. However, surgery is still considered the most appropriate treatment for this pathology. We describe the case of a 50 -year-old woman who has undergone a breast conservative surgery for a little tumor, preoperatively diagnosticated by a fine needle aspiration biopsy (FNAB) as a well differentiated infiltrating carcinoma.

    Breast cancer can be classified into molecular sub-types that have distinct survival patterns. We evaluated the prognostic significance of breast cancer sub-types in a cohort of women taking part in the NEAT and BR9601 clinical trials comparing cyclophosphamide, methotrexate and fluorouracil (CMF) with ECMF (epirubicin and CMF). Furthermore, we evaluated whether the sub-types were predictive of the added benefit of epirubicin in these trials. Tumour tissue microarrays were stained and scored for ER, PR, HER2, EGFR and CK5/6. These were used to classify the tumours into six intrinsic sub-types. We used Cox regression to compare overall survival (OS), breast cancer-specific survival (BCSS) and relapse-free survival (RFS) in the different sub-groups. We also compared the effect of ECMF with CMF by sub-group. Immunohistochemistry data were available for 1,725 cases of whom 805 were luminal 1-basal negative. Median follow-up time was 7 years. The luminal 1-basal negative tumours were associated with the best prognosis in five years after surgery and the HER2-like tumours were associated with the poorest prognosis. There was little evidence for significant heterogeneity of this effect by tumour sub-type (OS p = 0.40, BCSS p = 0.53 RFS p = 0.50) - the largest additional benefit of epirubicin was in women with tumours of the 5-negative phenotype (OS HR = 0.39 95% CI: 0.21-0.73) and the smallest was in Luminal 1-basal negative tumours (OS HR = 0.86 95% CI: 0.64-1.16). We confirmed that breast cancer sub-types show distinct behaviour with differences in short- and long-term survival. The benefit of ECMF over CMF was statistically similar in all disease sub-types.

    Aim: To study the caspase-3-independent mechanisms in oridonin-induced MCF-7 human breast cancer cell apoptosis in vitro. Methods: The viability of oridonin-treated MCF-7 cells was measured by MTT (thiazole blue) assay. Apoptotic cells with condensed nuclei were visualized by phase contrast microscopy. Nucleoso-mal DNA fragmentation was assayed by agarose gel electrophoresis. The apoptotic ratio was determined by lactate dehydrogenase assay. Cell cycle alternation and mitochondrial membrane potential were measured by flow cytometric analysis. Bax, Bcl-2, caspase-3, caspase-9, heat shock protein (Hsp)90, p53, p-p53, p21, Poly (ADP-ribose) polymerase (PARP), and the inhibitor of caspase-activated Dnase (ICAD) protein expressions were detected by Western blot analysis. Results: Oridonin inhibited cell growth in a time- and dose-dependent manner. Cell cycle was altered through the upregulation of p53 and p21 protein expressions. Pan-caspase inhibitor Z-VAD-fmk and calpain inhibitor Ⅱ both decreased cell death ratio. Nucleosomal DNA fragmentation and the downregulation of △ψmit were detected in oridonin-induced MCF-7 cell apoptosis, which was involved in a postmitochondrial caspase-9-dependent pathway. Decreased Bcl-2 and Hsp90 expression levels and increased Bax and p21 expression levels were positively correlated with elevated levels of phosphorylated p53 phosphorylation. Moreover, PARP was partially cleaved by calpain rather than by capase-3. Conclusion: DNA damage provoked alternations in the mitochondrial and caspase-9 pathways as well as p53-mediated cell cycle arrest, but was not related to caspase-3 activity in oridonin-induced MCF-7 cells.

    A 38-year-old woman with early stage invasive breast cancer was treated with wide excision of the tumor, axillary lymph node dissection, and breast irradiation. Three years later, she gave birth to a normal baby. She attempted breast feeding and had full lactation from the untreated breast. The irradiated breast underwent only minor changes during pregnancy and postpartum but produced small amounts of colostrum and milk for 2 weeks postpartum. There are only a few reports of lactation after breast irradiation. These cases are reviewed, and possible factors affecting breast function after radiotherapy are discussed. Because of scant information available regarding its safety for the infant, nursing from the irradiated breast is not recommended.

    HER-2/ErbB2/Neu(HER-2), a member of the epidermal growth factor receptor family, is specifically overexpressed on the surface of breast cancer cells and serves a therapeutic target for breast cancer. In this study, we aimed to isolate DNA aptamer (Ap) that specifically bind to a HER-2 overexpressing SK-BR-3 human breast cancer cell line, using SELEX strategy. We developed a novel multifunctional composite micelle with surface modification of Ap for targeted delivery of paclitaxel. This binary mixed system consisting of Ap modified pluronic®F127 and chitosan could enhance PTX loading capacity and increase micelle stability. Polymeric micelles had a spherical shape and were self-assemblies of block copolymers of approximately 86.22 ± 1.45 nm diameter. PTX could be loaded with high encapsulation efficiency (83.28 ± 0.13%) and loading capacity (9.12 ± 0.34%). The release profile were 29%-35% in the first 12 h and 85%-93% after 12 d at pH 7.5 of receiving media. The IC50 doses by MTT assay showed the greater activity of nanoparticles loaded paclitaxel over free paclitaxel and killed cells up to 95% after 6 h. These results demonstrated unique assembly with the capacity to function as an efficient detection and delivery vehicle in the biological living system.

    Turning to faith in God or a higher spiritual power is a common way of coping with life-threatening disease such as cancer. Little, however, is known about religious faith among cancer patients in secular societies. The present study aimed at exploring the prevalence of religious faith among Danish breast cancer patients and at identifying whether socio-demographic, pre-cancer health status, clinical, and health behavior characteristics, including their use of complementary and alternative medicine (CAM), were associated with their degree of faith. Information on faith in God or a higher spiritual power and use of CAM was provided by a nationwide sample of 3,128 recurrence-free Danish women who had received surgery for early-stage breast cancer 15-16 months earlier. Socio-demographic, clinical, and health status variables were obtained from national longitudinal registries, and health behaviors had been assessed at 3-4 months post-surgery. Of the women, 47.3% reported a high degree of faith (unambiguous believers), 35.9% some degree of faith (ambiguous believers), while the remaining 16.8% were non-believers. Unambiguous believers were more likely than ambiguous believers to experience their faith as having a positive impact on their disease and their disease-related quality-of-life. When compared to non-believers, unambiguous believers were also older, had poorer physical function, and were more frequent users of CAM, and more inclined to believe that their use of CAM would have a beneficial influence on their cancer. Disease- and treatment-related variables were unrelated to faith. While overall religious faith appears equally prevalent among Danish and US breast cancer patients, the majority of Danish breast cancer patients experienced ambiguous faith, whereas the majority of US patients have been found to express unambiguous faith. Our results suggest that future studies may benefit from exploring the role of faith for health behaviors, adherence to

    Full Text Available Abstract Background Breast cancer is one of the leading causes of cancer morbidity and mortality worldwide. In Cameroon, breast cancer causes as many as 10.7 deaths per 100,000 women making it the second cause of cancer mortality. Better documenting women’s knowledge and practices on breast cancer and breast self-exam (BSE would be useful in the design of interventions aimed at preventing breast cancer. This study sought to 1. describe Cameroonian women’s knowledge of breast self-examination (BSE; 2. assess their impression on the practice of BSE and 3. describe their perceptions on the causes, risk factors and prevention of breast cancer. Methods A cross-sectional survey was conducted in a volunteer sample of 120 consenting women in Buea, Cameroon. Data were collected using a structured questionnaire self-administered by study participants. Results The sample was fairly educated with close to three quarters (70.83% having completed high school. Nearly three quarters (74.17% of participants had previously heard about BSE, however as many as 40% had never done a BSE. Although 95% of participants believed that breast cancer could be prevented, only 36.67% recognized breast examination as a prevention method. A substantial 13.33% thought that breast cancer could be prevented with a vaccine while 45% thought that dieting or exercising would prevent breast cancer. Similarly, 70% of participants thought that breast cancer could be treated, with 35.83% thinking that it could be treated medically while 34.17% thought it could be treated traditionally or spiritually. Conclusions The practice of BSE while perceived as being important is not frequent in these women in Buea, Cameroon. Health education campaigns are imperative to elucidate the public on the causes, risk factors and prevention of breast cancer. Further studies need to explore what interventions could be best used to improve the uptake and practice of BSE.

    Inflammatory breast cancer (IBC) is the most aggressive entity of breast cancer. Management involves coordination of multidisciplinary management and usually includes neoadjuvant chemotherapy, ablative surgery if a tumor-free resection margin is expected and locoregional radiotherapy. This multimodal therapeutic approach has significantly improved patient survival. However, the median overall survival among women with IBC is still poor. By elucidating the biologic characteristics of IBC, new treatment options may become available. We performed a comprehensive review of the English-language literature on IBC through computerized literature searches. The objective of the current review is to present an overview of the literature related to the biology, imaging and multidisciplinary treatment of inflammatory breast cancer.

    Breast cancer is a disease many will experience. Depending on the size of the cancer, the size of the host breast, and whether it is multi-focal, a mastectomy may be recommended as part of the treatment. If this is the case, an immediate breast reconstruction may be offered. This article will describe the three main types of breast reconstruction and discuss pertinent issues regarding this, including complications, surgery to the other (contraleteral) breast and potential psychological implications of this surgery.

    Breast cancer is a multifactorial disease and the most commonly diagnosed cancer in women. Traditional risk factors for breast cancer include reproductive status, genetic mutations, family history and lifestyle. However, increasing evidence has identified an association between breast cancer and occupational factors, including environmental stimuli. Epidemiological and experimental studies demonstrated that ionizing and non-ionizing radiation exposure, night-shift work, pesticides, polycyclic aromatic hydrocarbons and metals are defined environmental factors for breast cancer, particularly at young ages. However, the mechanisms by which occupational factors can promote breast cancer initiation and progression remains to be elucidated. Furthermore, the evaluation of occupational factors for breast cancer, particularly in the workplace, also remains to be explained. The present review summarizes the occupational risk factors and the associated mechanisms involved in breast cancer development, in order to highlight new environmental exposures that could be correlated to breast cancer and to provide new insights for breast cancer prevention in the occupational settings. Furthermore, this review suggests that there is a requirement to include, through multidisciplinary approaches, different occupational exposure risks among those associated with breast cancer development. Finally, the design of new epigenetic biomarkers may be useful to identify the workers that are more susceptible to develop breast cancer.

    There are many questions that have to be answered concerning the role of radiotherapy in the management of primary breast cancer. Hopefully, prospective clinical trials will provide some answers, but more basic research into the biology of breast cancer and the host-tumor relationship will be needed. There are indications that radiotherapy alone, or following minimal extirpative surgery in selected cases, may be as effective for control of breast cancer as conventional mastectomies. The role of radiotherapy following segmental mastectomy, with or without axillary dissection, needs to be clarified. The possibility exists that high LET (linear energy transfer) radiation such as neutron or pi meson beams may provide better local control than conventional radiation. Thus, it may be possible to treat effectively all primary breast cancers with such radiations and obviate the need for any type of mastectomy. It remains to be demonstrated whether adjuvant chemotherapy is as effective as radiotherapy in preventing chest wall and regional node recurrences. If it is not, there may be a place for both adjuvant chemotherapy and radiotherapy in the treatment of operable cancer of the breast. Likewise, effective chemotherapy combined with radiotherapy may increase the local and regional control achieved with radiotherapy alone and make more primary lesions suitable for treatment without mastectomy. Meyer (1970) recently called attention to the leukopenia and cellualr immune deficiency produced by irradiation to the thorax and mediastinum. Further study is necessary to define exactly how much immunosuppression results from radiotherapy, its clinical significance and what can be done to avoid or counter it. If Stjervsward's thesis (1974) concerning the deleterious effects of radiotherapy on survival is correct, then it is of great importance to identify those patients most likely to be adversely affected by radiotherapy. Conversely, it may be possible in the future to identify a

    Breast cancer is the most common malignancy among women in the Western society. Over the past decades it has become apparent that breast cancer incidence rates are increasing steadily, whereas the mortality rates for breast cancer have remained relatively constant. Information through the media on this rising number of cases has increased breast health awareness but has also introduced anxiety in the female population. This combination of factors has made the need for prevention of breast cancer an urgent matter. Breast cancer does not seem to be a single disease entity. A specific etiologic factor may therefore have more influence on one form may therefore have more influence on one form of breast cancer than another. So far though, as shown in their summary of current knowledge on established and dubious risk factors, no risk factors have been identified that can explain a major part of the incidence. Efforts to identify other ways for primary prevention have also been discouraging, even though breast cancer is one of the most investigated tumours world-wide. Thus, at this point i time, the most important strategy to reduce breast cancer mortality is early detection through individual counselling and organised breast screening programs. The recent isolation of breast cancer susceptibility genes may introduce new ways to reduce the risk of breast cancer in a small subset of women.

    Highlights: • The addition of supplemental US to mammography depicted additional 5.0 cancers per 1000 postoperative women. • Positive biopsy rate of mammography-detected lesions was 66.7% (4 of 6) and that of US-detected lesions was 40.0% (6 of 15). • US can be helpful to detect mammographically occult breast cancer in the contralateral breast in women with previous history of cancer and dense breast. - Abstract: Objective: To determine whether supplemental screening ultrasound (US) to mammography could improve cancer detection rate of the contralateral breast in patients with a personal history of breast cancer and dense breasts. Materials and methods: During a one-year study period, 1314 screening patients with a personal history of breast cancer and dense breasts simultaneously underwent mammography and breast US. BI-RADS categories were given for mammography or US-detected lesions in the contralateral breast. The reference standard was histology and/or 1-year imaging follow-up, and the cancer rate according to BI-RADS categories and cancer detection rate and positive biopsy rate according to detection modality were analyzed. Results: Of 1314 patients, 84 patients (6.4%) were categorized as category 3 with one interval cancer and one cancer which was upgraded to category 4A after 6-month follow-up US (2.5% cancer rate, 95% CIs 1.5–9.1%). Fifteen patients (1.1%) had category 4A or 4B lesions in the contralateral breast. Four lesions were detected on mammography (two lesions were also visible on US) and 11 lesions were detected on US and 5 cancers were confirmed (33.3%, 95% CIs 15.0–58.5%). Six patients (0.5%) had category 4C lesions, 2 detected on mammography and 4 on US and 4 cancers were confirmed (66.7%, 95% CIs 29.6–90.8%). No lesions were categorized as category 5 in the contralateral breast. Cancer detection rate by mammography was 3.3 per 1000 patients and that by US was 5.0 per 1000 patients, therefore overall cancer detection rate by

    Full Text Available Abstract Introduction Pregnancy-associated breast cancer refers to breast cancer diagnosed during pregnancy, lactation, or within twelve months postpartum. Recent studies suggest that, when matched for age and stage, the prognosis of pregnancy-associated breast cancer is comparable to non-pregnancy-associated breast cancer. However, the risk for breast cancer recurrence associated with subsequent pregnancies in this population is not clear. Case presentation We describe the case of a Caucasian woman who was initially treated for pregnancy-associated breast cancer at age 23, three months after the birth of her third child. She underwent a total mastectomy with axillary node dissection, followed by chemotherapy and hormonal therapy. Ten years later, when the patient was 24 weeks pregnant with her fourth child, she presented with an ipsilateral chest wall recurrence of breast cancer. To the best of our knowledge, this represents the first reported case of a pregnancy-associated recurrence in a patient previously treated for pregnancy-associated breast cancer. Conclusion The case described here is the first report of a second occurrence of pregnancy-associated breast cancer. This case raises the possibility that pregnancy may represent a unique trigger for breast malignancy in a specific cohort of women. Although there is data showing no increase in the risk of recurrence for women who become pregnant after breast cancer treatment, pregnancy-associated breast cancer may be a distinct clinical category where subsequent pregnancies after treatment may confer an increased risk of recurrent disease.

    Full Text Available Abstract Background NUCKS (Nuclear, Casein Kinase and Cyclin-dependent Kinase Substrate is a nuclear, DNA-binding and highly phosphorylated protein. A number of reports show that NUCKS is highly expressed on the level of mRNA in several human cancers, including breast cancer. In this work, NUCKS expression on both RNA and protein levels was studied in breast tissue biopsies consisted of invasive carcinomas, intraductal proliferative lesions, benign epithelial proliferations and fibroadenomas, as well as in primary cultures derived from the above biopsies. Specifically, in order to evaluate the level of NUCKS protein in correlation with the histopathological features of breast disease, immunohistochemistry was employed on paraffin sections of breast biopsies of the above types. In addition, NUCKS expression was studied by means of Reverse Transcription PCR (RT-PCR, real-time PCR (qRT-PCR and Western immunoblot analyses in the primary cell cultures developed from the same biopsies. Results The immunohistochemical Results showed intense NUCKS staining mostly in grade I and II breast carcinomas compared to normal tissues. Furthermore, NUCKS was moderate expressed in benign epithelial proliferations, such as adenosis and sclerosing adenosis, and highly expressed in intraductal lesions, specifically in ductal carcinomas in situ (DCIS. It is worth noting that all the fibroadenoma tissues examined were negative for NUCKS staining. RT-PCR and qRT-PCR showed an increase of NUCKS expression in cells derived from primary cultures of proliferative lesions and cancerous tissues compared to the ones derived from normal breast tissues and fibroadenomas. This increase was also confirmed by Western immunoblot analysis. Although NUCKS is a cell cycle related protein, its expression does not correlate with Ki67 expression, neither in tissue sections nor in primary cell cultures. Conclusion The results show overexpression of the NUCKS protein in a number of non

    A 69-year old woman was admitted to our hospital because of dyspnea and pain in her left breast. Computed tomography revealed a massive quantity of left pleural effusion, a tumor in the left breast(5 cm in diameter), left cervical and supraclavicular lymph node metastasis, and a large left axillary metastatic mass. Based on a core needle biopsy, her breast tumor was diagnosed pathologically as scirrhous carcinoma, which was positive for estrogen receptor/progesterone receptor and negative for HER2 using the FISH assay, and left pleural metastasis was diagnosed cytologically. The carcinomatous pleural effusion was successfully controlled using pleural instillations of pirarubicin HCl and OK-432 after pleural drainage. A near clinical complete response was achieved by EC systemic chemotherapy(6 months)followed by endocrine therapy(letrozole), but 3 months later she was diagnosed cytologically with carcinomatous cardiac tamponade. After operative pericardial drainage, intrapericardial instillations of cisplatin and OK-432 successfully prevented re-accumulation of pericardial effusion. Systemic chemotherapy(weekly paclitaxel)for 11 months and endocrine therapy(letrozole)resulted in a clinical complete response. One year and 10 months after pericardial drainage, she underwent surgery(mastectomy and axillary lymph node dissection level II)because of two small tumors in the left breast which were found to be malignant using PET-CT. One tumor(diameter 1.6 cm)was found pathologically to consist of degenerated cancer cells, and another tumor(diameter 2 cm)was diagnosed as recurrent cancer. There was no lymph node metastasis in the axilla except for a single mass(1.4×0.7×0.3 cm), which was composed of extremely degenerative and necrotic non-lymphoid cancerous tissue. Since having the surgery, she has not experienced recurrence on hormone therapy with fulvestrant, and to date she is still alive, 3 years and 5 months since the left pleural metastasis episode.

Methods: From March 2011 to June 2015, female patients with operable breast cancer who had received docetaxel- or paclitaxel-containing adjuvant chemotherapy were included in this study. All patients were treated with single-agent paclitaxel intravenously (IV 175 mg/m2 every 3 weeks for four cycles, or IV 80 mg/m2 weekly for 12 cycles, and IV 100 mg/m2 docetaxel for four cycles as adjuvant treatment. We evaluated the relationship between neurotoxicity of taxanes and single-nucleotide polymorphisms of ABCB1, CYP3A4, ERCC1, ERCC2, FGFR4, TP53, ERBB2, and CYP2C8 genes. Taxane-induced neurotoxicity during the treatment was evaluated according to the National Cancer Institute Common Toxicity Criteria version 4.03 prior to each cycle. Chi-squared tests were used to compare the two groups, and multivariate binary logistic regression models were used for determining possible risk factors of neuropathy. Results: Pharmacogenetic analysis was performed in 219 females. ABCB1 3435 TT genotype had significantly higher risk for grade ≥2 neurotoxicity (odds ratio [OR]: 2.759, 95% confidence interval [CI]: 1.172–6.493, P: 0.017 compared to TC and CC genotype, and also CYP3A4 392 AA and AG genotype had significantly higher risk for grade ≥2 neurotoxicity (OR: 2.259, 95% CI: 1.033–4.941, P: 0.038 compared to GG genotype.

    Full Text Available Nifedipine is widely used as a calcium channel blocker (CCB to treat angina and hypertension,but it is controversial with respect the risk of stimulation of cancers. In this study, we demonstrated that nifedipine promoted the proliferation and migration of breast cancer cells both invivo and invitro. However, verapamil, another calcium channel blocker, didn't exert the similar effects. Nifedipine and high concentration KCl failed to alter the [Ca2+]i in MDA-MB-231 cells, suggesting that such nifedipine effect was not related with calcium channel. Moreover, nifedipine decreased miRNA-524-5p, resulting in the up-regulation of brain protein I3 (BRI3. Erk pathway was consequently activated and led to the proliferation and migration of breast cancer cells. Silencing BRI3 reversed the promoting effect of nifedipine on the breast cancer. In a summary, nifedipine stimulated the proliferation and migration of breast cancer cells via the axis of miRNA-524-5p-BRI3-Erk pathway independently of its calcium channel-blocking activity. Our findings highlight that nifedipine but not verapamil is conducive for breast cancer growth and metastasis, urging that the caution should be taken in clinic to prescribe nifedipine to women who suffering both hypertension and breast cancer, and hypertension with a tendency in breast cancers.

    Docetaxel is an antineoplastic drug from the taxane family that inhibits tubulin polymerization. Its brand name is Taxotere. In mid-2010, the formulation of Taxotere changed from a two-vial preparation needing a predilution (T2V) to a one-vial ready-to-use preparation (T1V). The aim of this study was to compare the toxicity profile of these two formulations. This retrospective observational and monocentric study included all patients who received Taxotere-based chemotherapy (100 mg/m) as an adjuvant or a neoadjuvant treatment for localized breast cancer, following initial treatment with anthracycline-based chemotherapy. Patients received either T2V or T1V Taxotere depending on the period of treatment. The main endpoint was the ratio of the dose of Taxotere received to that scheduled (R=docetaxel dose received/docetaxel dose scheduled). The secondary endpoint was tolerance. A total of 97 patients were included: 39 in the T2V group and 58 in the T1V group. The ratio of docetaxel received/docetaxel scheduled was significantly lower in the T1V than in the T2V group (0.83 vs. 0.95, respectively; P=0.028). A higher proportion of patients did not receive the totality of the scheduled dose in the T1V than in the T2V group (28 vs. 8%, respectively; P=0.03). Furthermore, the proportion of patients experiencing cutaneous toxicity was significantly higher in the T1V than in the T2V group (50 vs. 15%, respectively; P<0.001) as well as for neurological toxicity (31 vs. 15%, respectively; P=0.03). The frequency of grade 3 toxicities was higher in the T1V than in the T2V group (50 vs. 8%, P=0.016). The frequency of idiosyncratic toxicities was not affected by the change of formulation (4.7 vs. 5.4%, P=0.98). This study shows that patients treated with the T1V formulation received a significantly smaller dose of Taxotere than patients treated with T2V. In this small retrospective study, no conclusions can be drawn as to why a change in formulation would be associated with

    Full Text Available Second to the cardiovascular disease, cancer is the main cause of death in Iran. In this study some of the risk factors of breast cancer; especially the ones related to breastfeeding have been assessed. The study was a retrospective study of 100 women with breast cancer. The most important risk factors in breast cancer were number of children, age of mother on the first pregnancy. The result showed that the increase of breast cancer was related to women who stopped breastfeeding before age 24 months. Breastfeeding for more than 12 months will reduce the incidence of breast cancer by 25%. In general there was a reverse relationship between duration of breastfeeding and risk of cancer in premonopausal, but not in postmenopausal women.

    Full Text Available Purpose: Human papillomaviruses (HPV may have a role in some breast cancers. The purpose of this study is to fill important gaps in the evidence. These gaps are: (i confirmation of the presence of high risk for cancer HPVs in breast cancers, (ii evidence of HPV infections in benign breast tissues prior to the development of HPV positive breast cancer in the same patients, (iii evidence that HPVs are biologically active and not harmless passengers in breast cancer.Methods: RNA-seq data from The Cancer Genome Atlas (TCGA was used to identify HPV RNA sequences in breast cancers. We also conducted a retrospective cohort study based on polymerase chain reaction (PCR analyses to identify HPVs in archival specimens from Australian women with benign breast biopsies who later developed breast cancer. To assess whether HPVs in breast cancer were biologically active, the expression of the oncogenic protein HPV E7 was assessed by immunohistochemistry (IHC.Results: Thirty (3.5% low risk and 20 (2.3% high risk HPV types were identified in 855 breast cancers from the TCGA data base. The high risk types were HPV 18 (48%, HPV 113 (24%, HPV 16 (10%, HPV 52 (10%. Data from the PCR cohort study, indicated that HPV type 18 was the most common type identified in breast cancer specimens (55% of 40 breast cancer specimens followed by HPV 16 (13%. The same HPV type was identified in both the benign and subsequent breast cancer in 15 patients. HPV E7 proteins were identified in 72% of benign breast specimens and 59% of invasive breast cancer specimens.Conclusions: There were 4 observations of particular interest: (i confirmation by both NGS and PCR of the presence of high risk HPV gene sequences in breast cancers, (ii a correlation between high risk HPV in benign breast specimens and subsequent HPV positive breast cancer in the same patient, (iii HPVs in breast cancer are likely to be biologically active (as shown by transcription of HPV DNA to RNA plus the expression of

    Full Text Available The thyroid is an unusual site to find cancer metastasis. When it does occur, such cancer spread is often manifested in multiple metastases and generally suggests a poor prognosis. We presented here a 49-year-old woman recently diagnosed with thyroid cancer, who had been treated for stage IIA breast cancer 8 years ago. After radical right thyroidectomy and left subtotal thyroidectomy, her pathological report showed papillary thyroid carcinoma, right thyroid, with concomitant metastatic breast carcinoma. This is the first case of which we are aware involving coexisting thyroid cancer and metastatic breast cancer in the ipsilateral lobe. Moreover, the circumstances of this case show a very unique clinical course compared with previous studies. Given the unusual circumstances of our case, we further discuss the relationship between thyroid cancer and breast cancer.

    The Fiber Hypothesis which had its origins in the work of Burkitt and others in the early 1970's, focussed largely on fiber's beneficial effects on colon cancer and disorders of the gastric intestinal tract. In the 1980's it was proposed that fiber may also have beneficial effects on breast cancer and a rational for this was proposed involving modulation, by fiber, of the enterohepatic recirculation of estrogens. In the following the evidence from epidemiology, clinical interventions and animal model studies, supporting a role for fiber in breast cancer is critically reviewed. Evidence from animal model studies support the notion that supplementary fiber inhibits chemically-induced mammary tumorigenesis but do not support an estrogen-based mechanism. Some studies in human populations suggest modulation by estrogens and some do not. The aggregate data point to minor constituents present in fiber, such as isoflavones and phytate as the biologically active components of fiber which may be responsible for its anti cancer effects.

    Background Many researches suggested that obesity increased the risk of breast cancer, but the mechanism was currently unknown. Adipocytokines might mediate the relationship. Our study was aimed to investigate the relationship between serum levels of resistin, adiponectin and leptin and the onset, invasion and metastasis of breast cancer.Methods Blood samples were collected from 80 newly diagnosed, histologically confirmed breast cancer patients and 50 age-matched healthy controls. Serum levels of resistin, adiponectin and leptin were determined by enzyme-linked immunosorbent assays (ELISA); fasting blood glucose (FBG), lipids, body mass index (BMI), and waist circumference (WC) were assayed simultaneously.Results Serum levels of adiponectin ((8.60±2.92) mg/L vs (10.37±2.81) mg/L, P=0.001) and HDL-c were significantly decreased in breast cancer patients in comparison to controls. Serum levels of resistin ((26.35±5.36) μg/L vs (23.32±4.75)μg/L, P=0.000), leptin ((1.35±0.42) μg/L vs (1.06±0.39) μg/L, P=0.003), FBG and triglyceride (TG) in breast cancer patients were increased in contrast to controls, respectively. However, we did not find the significant difference of the serum levels of resistin, adiponectin and leptin between premenopausal breast cancer patients and healthy controls (P=0.091, 0.109 and 0.084, respectively). The serum levels of resistin, adiponectin and leptin were significantly different between patients with lymph node metastasis (LNM) and those without LNM (P=0.001, 0.000 and 0.006, respectively).The stepwise regression analysis indicated that the tumor size had the close correlation with leptin (R2=0.414, P=0.000)and FBG (R2=0.602, P=0.000). Logistic regression analysis showed that reduced serum levels of adiponectin (OR:0.805;95%CI: 0.704-0.921; P=0.001), HDL (OR: 0.087; 95%CI: 0.011-0.691, P=0.021), elevated leptin (OR:2.235;95%CI:1.898-4.526; P=0.004) and resistin (OR: 1.335; 95%CI: 1.114-2.354; P=0.012) increased the risk for

METHODS: transversal study with 110 women treated for breast cancer, for at least one year in the Centro de Atenção Integral à Saúde da Mulher of UNICAMP. The quality of life was assessed by the WHOQOL-bref questionnaire, and the issues on sexuality, by a specific questionnaire in which Cronbach's Alpha coefficient was used to validate the concordance of responses (alpha=0.72 and the technique of factor analysis, with the criterion of self value and variance maximum rotation, resulting in two components: intrinsic or intimacy ( how the woman sees herself sexually and extrinsic or attractiveness (how the woman believes the others see her sexually. Sociodemographic variables have been assessed according to the WHO questionnaire, and the sexuality components, through the Kruskal-Wallis followed by the Mann-Whitney's test and Spearman correlation test. RESULTS: age, schooling, type of surgery and lapse of time from the surgery did not influence the quality of life concerning physical, environmental, and psychological aspects, as well as the social relationships. Women with a stable marital relationship got higher scores in the psychological area (p=0.04 and in the area of social relationships (p=0.02.

    Background Breast cancer is one of the most common cancers diagnosed during pregnancy. Pregnancy-associated breast cancer (PABC) is defined as breast cancer diagnosed during pregnancy or within 12 months of delivery. Nowadays PABC can be safely diagnosed, staged, and treated during pregnancy with good outcomes for both the mother and the fetus. Recent studies suggest that prognosis of women diagnosed during postpartum seems to be worse. In order to gain a better understanding of the PABC, we reviewed our centre’s experience. Patients and methods We assessed the clinicopathological parameters, evolution, and outcome of patients treated in the Fundación Instituto Valenciano de Oncología of Valencia, Spain, from October 1990 to October 2013, and compared the results of patients diagnosed during pregnancy (group ‘A’) and patients diagnosed within one year of delivery (group ‘B’). Of 12,000 cases of breast cancer registered in our database, 35 cases of PABC were identified. We included 11 patients in group ‘A’ and 24 in group ‘B’. Results In our group the median age was 35 years (range 29–42), of which ten (28%) patients had family history (first grade) of breast cancer, four patients were BRCA 1 mutation carriers. Axillary node compromise was found in 19 patients (53.5%), 24 patients were stage II or III at diagnosis (68.5%), 22 (62.8%) were ER positive, and nine (25.7%) were HER-2 positive. In group A (n = 11), five patients diagnosed before 18th week decided that a therapeutic abortion be performed before treatment, two patients were treated during pregnancy, one with chemotherapy without treatment associated complications during delivery. Four women diagnosed after 28th week decided to delay the treatment until delivery. After a follow up of 172 months, the relapse free survival (RFS) was 69% at five years and 45% at ten years. Overall survival (OS) at five years was 90.8% and 74.2% at ten years for all patients. For group ‘A’ OS was higher

  15. Resistance to Trastuzumab in Breast Cancer.

    Pohlmann, Paula R; Mayer, Ingrid A; Mernaugh, Ray

    2009-12-15

    HER2 is a transmembrane oncoprotein encoded by the HER2/neu gene and is overexpressed in approximately 20 to 25% of invasive breast cancers. It can be therapeutically targeted by trastuzumab, a humanized IgG1 kappa light chain monoclonal antibody. Although trastuzumab is currently considered one of the most effective treatments in oncology, a significant number of patients with HER2-overexpressing breast cancer do not benefit from it. Understanding the mechanisms of action and resistance to trastuzumab is therefore crucial for the development of new therapeutic strategies. This review discusses proposed trastuzumab mode of action as well as proposed mechanisms for resistance. Mechanisms for resistance are grouped into four main categories: (1) obstacles preventing trastuzumab binding to HER2; (2) upregulation of HER2 downstream signaling pathways; (3) signaling through alternate pathways; and (4) failure to trigger an immune-mediated mechanism to destroy tumor cells. These potential mechanisms through which trastuzumab resistance may arise have been used as a guide to develop drugs, presently in clinical trials, to overcome resistance. The mechanisms conferring trastuzumab resistance, when completely understood, will provide insight on how best to treat HER2-overexpressing breast cancer. The understanding of each mechanism of resistance is therefore critical for the educated development of strategies to overcome it, as well as for the development of tools that would allow definitive and efficient patient selection for each therapy.

    Full Text Available Surgery and irradiation for breast cancer may interfere with conventional pathways of spread, leading to bizarre patterns of dissemination through lymphatics or through hematogenous route. Lymphoscintigraphic studies may help identify nodal involvement. Other possible reasons could be occurrence of primary breast cancer in accessory breast tissue retained in the vulva following involution of milk line. We describe a case of triple negative breast cancer, who developed contralateral breast cancer during treatment. Three years later, she developed isolated inguinal nodal metastases, which responded to local radiotherapy and chemotherapy. However, the patient relapsed after 2 years and could not be salvaged thereafter.

    An early diagnostic biomarker for breast cancer is essential to improve outcome. High precision isotopic analysis, originating in Earth sciences, can detect very small shifts in metal pathways. For the first time, the natural intrinsic Zn isotopic compositions of various tissues in breast cancer patients and controls were determined. Breast cancer tumours were found to have a significantly lighter Zn isotopic composition than the blood, serum and healthy breast tissue in both groups. The Zn isotopic lightness in tumours suggests that sulphur rich metallothionein dominates the isotopic selectivity of a breast tissue cell, rather than Zn-specific proteins. This reveals a possible mechanism of Zn delivery to Zn-sequestering vesicles by metallothionein, and is supported by a similar signature observed in the copper isotopic compositions of one breast cancer patient. This change in intrinsic isotopic compositions due to cancer has the potential to provide a novel early biomarker for breast cancer.

    2015-01-01

    Objective The aim of the study was to investigate the inhibitory ef ects of dendritic cel s (DCs) loaded with resistant breast cancer antigens on breast cancer in nude mice. Methods A single-cel suspension was prepared from a primary breast cancer and chemotherapeutic drugs were screened using the ATP-PCA susceptibility testing system. Cancer cel s were treated with 1/10 × IC50, 1/5 × IC50, 1/2 × IC50, 1 × IC50, and 2 × IC50 medium until their growth became steady in the 2 × IC50 medium. Peripheral blood mononuclear cel s (PBMCs) were obtained from the peripheral blood of patients with leukapheresis. The obtained adherent cel s were induced by granulocyte-macrophage colony-stimu-lating factor (GM-CSF) and interleukin-4 (IL-4) to generate DCs, which carried resistant strain cel lysis compounds or non-treated cancer cel lysis compounds. The former mature DCs carried resistant breast tumor antigens. A breast tumor-bearing nude mouse model was established with these resistant strains and the mice were randomly divided in three groups. The mice in the treatment group were injected with DCs loaded with resistant breast cancer antigens. The control group consisted of mice injected with DCs loaded with primary tumor cel antigens and the blank group consisted of mice injected with the same volume of normal saline. Changes in the cancers were observed. Results After treatment with the ef ector cel s, the cancer volume and weight were significantly dif erent to those before treatment in every group of mice (P Conclusion DCs loaded with resistant breast cancer antigens demonstrated a significant inhibition ef ect on the cancers of breast tumor-bearing nude mice.

    The purpose of this study was to examine the relationship between self-reported exercise behavior, cardiorespiratory fitness (CRF), and cognitive function in early breast cancer patients. Thirty-seven breast cancer patients following completion of chemotherapy (median 16 months) and 14 controls were studied. Cognitive function was assessed using the Central Nervous System (CNS) Vital Signs software (CNS Vital Signs, LLC, Morrisville, N.C., USA), a computerized test battery consisting of 9 cognitive subtests. Exercise behavior was evaluated using the Godin Leisure Time Exercise Questionnaire, and CRF was assessed via a cardiopulmonary exercise test to assess peak oxygen consumption. Patients' mean total exercise was 184 ± 141 min·week(-1) compared with 442 ± 315 min·week(-1) in controls (p exercise guidelines (i.e., ≥150 min of moderate-intensity or vigorous exercise per week) compared with 57% of controls (p = 0.014). Patients' peak oxygen consumption averaged 23.5 ± 6.3 mL·kg(-1)·min(-1) compared with 30.6 ± 7.0 mL·kg(-1)·min(-1) in controls (p exercise, peak oxygen consumption, and the majority of cognitive subdomain scores; however, there was a significant positive correlation between exercise and visual memory (r = 0.47, p = 0.004). In conclusion, breast cancer patients following the completion of primary adjuvant chemotherapy exhibit, in general, worse cognitive performance than healthy women from the general population, and such performance may be related to their level of exercise behavior.

    Protein kinases are arguably the most tractable candidates for development of new therapies to treat cancer.Deep sequencing of breast cancer cell lines indicates each express 375or so kinases,representing nearly 75% of the kinome.A rich network both downstream and upstream from key oncogenic kinases includes both tyrosine and serine/threonine kinases,giving plasticity and resiliency to the cancer cell kinome. Protein kinases have proven to be highly tractable candidates for development of new cancer therapies with over 130 kinase-specific inhibitors currently in Phase 1-3 clinical trials [ 1].Approximately 518 protein kinases are encoded by the human genome,collectively referred to as the kinome.

    The introduction of cisplatin in cancer treatment represents an important achievement in the oncologic field. Many types of cancers are now treated with this drug, and in testicular cancer patients major results are reached. Since 1965, other compounds were disovered and among them carboplatin and oxaliplatin are the main Cisplatin analogues showing similar clinical efficacy with a safer toxicity profile. Lipoplatin is a new liposomal cisplatin formulation which seems to have these characteristics. Lipoplatin was shown to be effective in NSCLC both in phase 2 and phase 3 trials, with the same response rate of Cisplatin, a comparable overall survival but less toxicity. A new protocol aiming to elucidate the double capacity of Lipoplatin to act as a chemotherapeutic and angiogenetic agent in triple-negative breast cancer patients is upcoming.

    The relapse of cancer is mostly due to the proliferation of cancer stem cells which could not be eliminated by a standard chemotherapy. A new kind of all-trans retinoic acid stealth liposomes was developed for preventing the relapse of breast cancer and for treating the cancer in combination with a cytotoxic agent, vinorelbine stealth liposomes. In vitro studies were performed on the human breast cancer MCF-7 and MDA-MB-231 cells. In vivo evaluations were performed on the newly established relapse model with breast cancer stem cells. Results showed that the particle size of all-trans retinoic acid stealth liposomes was approximately 80nm, and the encapsulation efficiency was >90%. Breast cancer stem cells were identified with the CD44(+)/CD24(-) phenotype and characterized with properties: resistant to cytotoxic agent, stronger capability of proliferation, and stronger capability of differentiation. Inhibitory effect of all-trans retinoic acid stealth liposomes was more potent in cancer stem cells than in cancer cells. The mechanisms were defined to be two aspects: arresting breast cancer stem cells at the G(0)/G(1) phase in mitosis, and inducing the differentiation of breast cancer stem cells. The cancer relapse model was successfully established by xenografting breast cancer stem cells into NOD/SCID mice, and the formation and growth of the xenografted tumors were significantly inhibited by all-trans retinoic acid stealth liposomes. The combination therapy of all-trans retinoic acid stealth liposomes with vinorelbine stealth liposomes produced the strongest inhibitory effect to the relapse tumor model. It could be concluded that all-trans retinoic acid stealth liposomes could be used for preventing the relapse of breast cancer by differentiating cancer stem cells and arresting the cell-cycle, and for treating breast cancer as a co-therapy, thus providing a novel strategy for treating breast cancer and preventing relapse derived from breast cancer stem cells.

    Full Text Available Abstract Background Breast cancer is one of the major public health problems among women worldwide. A number of epidemiological studies have been carried out to find the role of dietary fat and the risk of breast cancer. The main objective of the present communication is to summarize the evidence from various case-control and cohort studies on the consumption of fat and its subtypes and their effect on the development of breast cancer. Methods A Pubmed search for literature on the consumption of dietary fat and risk of breast cancer published from January 1990 through December 2003 was carried out. Results Increased consumption of total fat and saturated fat were found to be positively associated with the development of breast cancer. Even though an equivocal association was observed for the consumption of total monounsaturated fatty acids (MUFA and the risk of breast cancer, there exists an inverse association in the case of oleic acid, the most abundant MUFA. A moderate inverse association between consumption of n-3 fatty acids and breast cancer risk and a moderate positive association between n-6 fatty acids and breast cancer risk were observed. Conclusion Even though all epidemiological studies do not provide a strong positive association between the consumption of certain types of dietary fat and breast cancer risk, at least a moderate association does seem to exist and this has a number of implications in view of the fact that breast cancer is an increasing public health concern.

    There is limited data on co-expression of FGFR/FGR amplifications and PI3K/ AKT/mTOR alterations in breast cancer. Tumors from patients with metastatic breast cancer referred to our Phase I Program were analyzed by next generation sequencing (NGS). Genomic libraries were selected for all exons of 236 (or 182) cancer-related genes sequenced to average depth of >500× in a CLIA laboratory (Foundation Medicine, Cambridge, MA, USA) and analyzed for all classes of genomic alterations. We report genomic profiles of 112 patients with metastatic breast cancer, median age 55 years (range, 27-78). Twenty-four patients (21%) had at least one amplified FGFR or FGF. Fifteen of the 24 patients (63%) also had an alteration in the PI3K/ AKT/mTOR pathway. There was no association between alterations in FGFR/FGF and PI3K/AKT/mTOR (P=0.49). Patients with simultaneous amplification in FGFR/FGF signaling and the PI3K/AKT/mTOR pathway had a higher rate of SD≥6 months/PR/ CR when treated with therapies targeting the PI3K/AKT/mTOR pathway than patients with only alterations in the PI3K/AKT/mTOR pathway (73% vs. 34%; P=0.0376) and remained on treatment longer (6.8 vs. 3.7 months; P=0.053). Higher response rates were seen in patients with simultaneous amplification in FGFR/FGF signaling and alterations in the PI3K/AKT/mTOR pathway who were treated with inhibitors of that pathway.

    Aim: Resistance to trastuzumab (which is a standard therapy for breast cancer patients with HER2 overexpression) is associated with higher risk of progression or cancer death, and might be related to activation of signalling cascades (PI3K/AKT/mTOR, Ras/Raf/MAPK) and decreased level of their inhibitors. Material and methods: Formalin-fixed paraffin-embedded tumour specimens from 118 HER2-overexpressing breast cancer patients treated with radical local therapy and trastuzumab in adjuvant setting were used for the assessment of: (1) PIK3CA gene mutations (p.H1047R and p.E545K) by qPCR, and (2) expression of Ki-67, EGFR, MUC4, HER3 and PTEN by immunohistochemistry. Results: Lower Ki-67LI was observed in EGFR-immunonegative and in PTEN-immunopositive tumours. MUC4-immunonegative tumours more frequently were PTEN- and HER3-immunonegative. Favourable metastasis-free survival was observed in patients with tumours characterized by Ki-67LI≤50% (p=0.027), HER3 immunonegativity or PTEN immunopositivity (vs. tumours with HER3 expression and lack of PTEN expression, p=0.043), additionally, the trend was observed for patients with pN0+pN1 pathological tumour stage (vs. pN2+pN3) (p=0.086). Cox model revealed that independent negative prognostic factors were: (i) Ki-67LI>50% (p=0.014, RR=4.6, 95% CI 1.4-15.4), (ii) HER3 immunopositivity together with PTEN immunonegativity (p=0.034, RR=3.7, 95% CI 1.1-12.5). Conclusion: The results of our study suggest that combined analysis of HER3 and PTEN expression might bring information on trastuzumab sensitivity in the group of HER2-positive breast cancer patients treated with trastuzumab in adjuvant setting.

    Breast cancer is the most common malignant tumor-affecting women during the child bearing period. With the rising trend in delaying pregnancy later in life, the issue of subsequent pregnancy and lactation following breast cancer diagnosis has been more frequently encountered. In this context, data is scarce particularly those addressing the issue of lactation. In this review, we discussed different endocrinal, clinical and biological aspects dealing with breast-feeding after breast cancer in an attempt to determine how safe and feasible this approach is.

    Purpose: Postmastectomy radiation therapy (PMRT) remains controversial for patients with 1-3 positive lymph nodes (LN+). Methods and Materials: We conducted a retrospective review of all 369 breast cancer patients with 1-3 LN+ who underwent mastectomy without neoadjuvant systemic therapy between 2000 and 2007 at Cleveland Clinic. Results: We identified 271 patients with 1-3 LN+ who did not receive PMRT and 98 who did receive PMRT. The median follow-up time was 5.2 years, and the median number of LN dissected was 11. Of those not treated with PMRT, 79% received adjuvant chemotherapy (of whom 70% received a taxane), 79% received hormonal therapy, and 5% had no systemic therapy. Of the Her2/neu amplified tumors, 42% received trastuzumab. The 5-year rate of locoregional recurrence (LRR) was 8.9% without PMRT vs 0% with PMRT (P=.004). For patients who did not receive PMRT, univariate analysis showed 6 risk factors significantly (P<.05) correlated with LRR: estrogen receptor/progesterone receptor negative (hazard ratio [HR] 2.6), lymphovascular invasion (HR 2.4), 2-3 LN+ (HR 2.6), nodal ratio >25% (HR 2.7), extracapsular extension (ECE) (HR 3.7), and Bloom-Richardson grade III (HR 3.1). The 5-year LRR rate was 3.4% (95% confidence interval [CI], 0.1%-6.8%] for patients with 0-1 risk factor vs 14.6% [95% CI, 8.4%-20.9%] for patients with {>=}2 risk factors (P=.0006), respectively. On multivariate analysis, ECE (HR 4.3, P=.0006) and grade III (HR 3.6, P=.004) remained significant risk factors for LRR. The 5-year LRR was 4.1% in patients with neither grade III nor ECE, 8.1% with either grade III or ECE, and 50.4% in patients with both grade III and ECE (P<.0001); the corresponding 5-year distant metastasis-free survival rates were 91.8%, 85.4%, and 59.1% (P=.0004), respectively. Conclusions: PMRT offers excellent control for patients with 1-3 LN+, with no locoregional failures to date. Patients with 1-3 LN+ who have grade III disease and/or ECE should be strongly considered

    2014-01-01

    Hypercholesterolemia is a risk factor for estrogen receptor (ER) positive breast cancers and is associated with a decreased response of tumors to endocrine therapies. Here we show that 27-Hydroxycholesterol (27HC), a primary metabolite of cholesterol and an ER and Liver X receptor (LXR) ligand, increases ER-dependent growth and LXR-dependent metastasis in mouse models of breast cancer. The effects of cholesterol on tumor pathology required its conversion to 27HC by the cytochrome P450 oxidase CYP27A1, and were attenuated by treatment with CYP27A1 inhibitors. In human breast cancer specimens, CYP27A1 expression levels correlated with tumor grade. In high-grade tumors, both tumor cells and tumor-associated macrophages exhibited high expression levels of the enzyme. Thus, lowering circulating cholesterol levels or interfering with its conversion to 27HC may be a useful strategy to prevent and/or treat breast cancer. PMID:24288332

    2015-03-01

    All known cases of breast cancer in patients with a diagnosis consistent with transgender identification were identified in the Veterans Health Administration (1996-2013). Ten cases were confirmed: seven birth sex females and three birth sex males. Of the three birth sex males, two identified as gender dysphoric male-to-female and one identified as transgender with transvestic fetishism. The birth sex males all presented with late-stage disease that proved fatal, whereas most of the birth sex female transgender veterans presented with earlier stage disease that could be treated. These cases support the importance of screening for breast cancer using standard guidelines in birth sex males and females. Family history of breast cancer should be obtained from transgender people as part of routine care. This report expands the known cases of breast cancer in transgender persons from 5 to 12 (female-to-male) and from 10 to 13 (male-to-female).

    Objective: This study was performed to exam the relativeship between mammographic calcifications and breast cancer. Methods: All of the 184 patients with breast diseases underwent mammography before either an open biopsy or a mastectomy. The presence,morphology, and distribution of calcifications visualized on mammograms for breast cancer were compared with the controls who remained cancer free. Statistical comparisons were made by using the x2 test. Results:Of the 184 patients with breast diaeases, 93 malignant and 91 benign lesions were histologically confirmed.Calcifications were visualized on mammograms in 60(64%) of 93 breast cancers and 26 (28%) of 91 non breast cancers. The estimated odds ratio (OR) of breast cancer was 4.5 in women with calcifications seen on mammograms, compared with those having none (P<0.01). Of the 60 breast carcinomas having mammographic calcifications, 28 (47%) were infiltrating ductal carcinomas.There were only 8 (24%) cases with infiltrating ductal cancers in the group of without calcifications seen on the mammograms (P<0.05). Conclusion: Our finding suggests that mammographic calcification appears to be a risk factor for breast cancer. The granular and linear cast type calcification provide clues to the presence of breast cancer, especially when the carcinomas without associated masses were seen on mammograms.

    Men with a BRCA2 mutation face substantial lifetime risks for the development of both breast and prostate cancer. A male who was initially diagnosed with breast cancer at the age of 32 was subsequently diagnosed at age 77 with both contralateral breast cancer and prostate cancer. He was found to be BRCA2 mutation carrier. The patient was treated with contralateral mastectomy, breast irradiation, prostate irradiation and adjuvant endocrine therapy. At age 83 he died of metastatic prostate cancer. Our case underscores the observation that BRCA2 mutation carriers are at risk for multiple cancers, including contralateral breast cancer, and illustrates the need for current practice recommendations for the early detection of breast and prostate cancer in men with BRCA2 mutations.

    2010-01-01

    Breast cancer is the commonest malignancy among Singapore women, accounting for 29.7% of all female cancers, with an age-standardized rate of 54.9 per 100,000 per year. It has been the most frequent cancer in Singapore women for the last 30 years, with the highest rates previously reported in those aged between 45 and 49 years, but with a more recent observation of a change in peak age group to women in their late 50s. About 1,100 new cases are diagnosed annually and approximately 270 women die in Singapore each year from breast cancer. In the multiethnic population of Singapore, it has been noted that rising breast cancer incidence is consistent across all three ethnic groups (Chinese, Malays, and Indians). Singapore has among the highest breast cancer incidence in Asia. Possible explanations include rapid urbanization, improvement in socio-economic status, and adoption of a western lifestyle. Our experience with the Singapore breast screening pilot project (1994-1997) and the national breast-screening program (BreastScreen Singapore) has led to increased understanding of this disease in the country. Data from the pilot project showed that breast screening is just as effective in a predominantly Asian population as in the west. Early breast cancer accounted for most breast cancers detected, with pre-invasive ductal carcinoma in situ (DCIS) comprising 26% of all screen-detected cancers in the pilot study. In the currently on-going BreastScreen Singapore, DCIS forms >30% of all breast cancers among pre-menopausal women, a relatively high proportion probably accounted for partially by the greater participation of women aged between 40 and 49 years. Despite the ready availability of subsidized mammographic screening, there are still women in Singapore who present with locally advanced breast cancer. Clinical management of an increasing number of women with breast cancer embraces a multidisciplinary team-based approach, with regular discussions of therapeutic

    BACKGROUND: Preclinical studies have demonstrated that propranolol inhibits several pathways involved in breast cancer progression and metastasis. We investigated whether breast cancer patients who used propranolol, or other non-selective beta-blockers, had reduced breast cancer-specific or all......-cause mortality in eight European cohorts. METHODS: Incident breast cancer patients were identified from eight cancer registries and compiled through the European Cancer Pharmacoepidemiology Network. Propranolol and non-selective beta-blocker use was ascertained for each patient. Breast cancer-specific and all......-cause mortality were available for five and eight cohorts, respectively. Cox regression models were used to calculate hazard ratios (HR) and 95% confidence intervals (CIs) for cancer-specific and all-cause mortality by propranolol and non-selective beta-blocker use.

    There is substantial evidence indicating that the WNT signaling pathway is activated in various cancer cell types including breast cancer. Previous studies reported that FH535, a small molecule inhibitor of the WNT signaling pathway, decreased growth of cancer cells but not normal fibroblasts, suggesting this pathway plays a role in tumor progression and metastasis. In this study, we tested FH535 as a potential inhibitor for malignant phenotypes of breast cancer cells including migration, invasion, and growth. FH535 significantly inhibited growth, migration, and invasion of triple negative (TN) breast cancer cell lines (MDA-MB231 and HCC38) in vitro. We demonstrate that FH535 was a potent growth inhibitor for TN breast cancer cell lines (HCC38 and MDA-MB-231) but not for other, non-TN breast cancer cell lines (MCF-7, T47D or SK-Br3) when cultured in three dimensional (3D) type I collagen gels. Western blotting analyses suggest that treatment of MDA-MB-231 cells with FH535 markedly inhibited the expression of NEDD9 but not activations of FAK, Src, or downstream targets such as p38 and Erk1/2. We demonstrated that NEDD9 was specifically associated with CSPG4 but not with β1 integrin or CD44 in MDA-MB-231 cells. Analyses of gene expression profiles in breast cancer tissues suggest that CSPG4 expression is higher in Basal-type breast cancers, many of which are TN, than any other subtypes. These results suggest not only a mechanism for migration and invasion involving the canonical WNT-signaling pathways but also novel strategies for treating patients who develop TN breast cancer.

    Breast cancer is the most prevalent women's cancer, with an age-adjusted incidence of 122.9 per 100,000 US women. Cadmium, a ubiquitous carcinogenic pollutant with multiple biological effects, has been reported to be associated with breast cancer in one US regional case-control study. We examined the association of breast cancer with urinary cadmium (UCd), in a case-control sample of women living on Long Island (LI), NY (100 with breast cancer and 98 without), a region with an especially high rate of breast cancer (142.7 per 100,000 in Suffolk County) and in a representative sample of US women (NHANES 1999-2008, 92 with breast cancer and 2,884 without). In a multivariable logistic model, both samples showed a significant trend for increased odds of breast cancer across increasing UCd quartiles (NHANES, p=0.039 and LI, p=0.023). Compared to those in the lowest quartile, LI women in the highest quartile had increased risk for breast cancer (OR=2.69; 95% CI=1.07, 6.78) and US women in the two highest quartiles had increased risk (OR=2.50; 95% CI=1.11, 5.63 and OR=2.22; 95% CI=.89, 5.52, respectively). Further research is warranted on the impact of environmental cadmium on breast cancer risk in specific populations and on identifying the underlying molecular mechanisms.

    Full Text Available Brendan Corkery1,2, Norma O’Donovan2, John Crown1,21St. Vincent’s University Hospital, Dublin, Ireland; 2National Institute for Cellular Biotechnology, Dublin City University, Dublin, IrelandAbstract: Improved molecular understanding of breast cancer in recent years has led to the discovery of important drug targets such as HER-2 and EGFR. Lapatinib is a potent dual inhibitor of HER-2 and EGFR. Preclinical and phase I studies have shown activity with lapatinib in a number of cancers, including breast cancer, and the drug is well tolerated. The main known drug interactions are with paclitaxel and irinotecan. The most significant side-effects of lapatinib are diarrhea and adverse skin events. Rates of cardiotoxicity compare favorably with trastuzumab, a monoclonal antibody against HER-2. This paper focuses on lapatinib in advanced and metastatic breast cancer, which remains an important therapeutic challenge. Phase II and III studies show activity as monotherapy, and in combination with chemotherapy or hormonal agents. Results from these studies suggest that the main benefit from lapatinib is in the HER-2 positive breast cancer population. Combinations of lapatinib and trastuzumab are also being studied and show encouraging results, particularly in trastuzumab-refractory metastatic breast cancer. Lapatinib may have a specific role in treating HER-2 positive CNS metastases. The role of lapatinib as neoadjuvant therapy and in early breast cancer is also being evaluated.Keywords: HER-2, EGFR, erbB, lapatinib, Tykerb®, tyrosine kinase

    p53 mutation remains the most common genetic change identified in human neoplasia. In breast cancer, p53 mutation is associated with more aggressive disease and worse overall survival. The frequency of mutation in p53 is, however, lower in breast cancer than in other solid tumours. Changes, both genetic and epigenetic, have been identified in regulators of p53 activity and in some downstream transcriptional targets of p53 in breast cancers that express wild-type p53.

    The aim of our study was to estimate oxidative stress (by using different biomarkers of lipid peroxidation--isoprostanes and thiobarbituric acid reactive substances (TBARS)) in patients with invasive breast cancer, patients with benign breast diseases and in a control group. We observed a statistically increased level of TBARS in plasma and isoprostanes in urine of patients with invasive breast cancer in comparison with a control group. The concentration of tested biomarkers in plasma or urine from patients with invasive breast cancer was also higher than in patients with benign breast diseases. Moreover, the levels of tested markers in patients with benign breast diseases and in a control group did not differ. Considering the data presented in this study, we suggest that free radicals induce peroxidation of unsaturated fatty acid in patients with breast cancer.

    The relationship between diazepam and breast cancer was evaluated using data from a case-control study of breast cancer, in which 1075 cases and 1146 controls who were participants in a breast cancer screening program were interviewed. Diazepam use was negatively associated with extent of disease and lymph node involvement, and this effect seemed greatest for long-term users of diazepam. It is not certain to what extent these data reflect an ascertainment bias, an association with the reasons for which the drug was prescribed, or chance. Whatever the explanation, the findings do not support a previous contention that diazepam promotes or accelerates breast cancer growth.

    2011-12-01

    Full Text Available Breast cancer is the most frequent cancer among women and the leading cause of death among middle-aged women. Early detection by mammography screening and improvement of therapeutic options have increased breast cancer survival rates, with the consequence that late side effects of cancer treatment become increasingly important. In particular, patients treated with adjuvant chemotherapy regimens, commonly including alkylating agents and anthracyclines, are at increased risk of developing leukemia, further enhanced by the use of radiotherapy. In the last few years also the use of growth factors seems to increase the risk of secondary leukemia. The purpose of this review is to update epidemiology of therapy-related myeloid neoplasms occurring in breast cancer patients

  12. Counterview: Pre-operative breast MRI (magnetic resonance imaging) is not recommended for all patients with newly diagnosed breast cancer.

    Solin, Lawrence J

    2010-02-01

    For the woman with a newly diagnosed early stage breast cancer, the routine use of pre-operative breast MRI (magnetic resonance imaging) is not indicated beyond conventional breast imaging (i.e., mammography with correlation ultrasound as indicated). There is no consistent evidence that a pre-operative breast MRI confers a benefit to the patient by improving clinical outcomes or surgical procedures. In a meta-analysis of studies reporting on the use of pre-operative breast MRI for the patient with an established index cancer, multifocal or multicentric disease was found on breast MRI in 16% of the patients, a rate substantially higher than the rate of local recurrence after breast conserving surgery plus definitive radiation treatment. In the largest retrospective study of patients treated with breast conserving surgery plus radiation, no gain was found for adding a breast MRI to conventional breast imaging. No randomized clinical trial has been designed to evaluate long term clinical outcomes associated with adding a pre-operative breast MRI. Adding pre-operative breast MRI can alter clinical management in ways that are potentially harmful to patients, for example, increased ipsilateral mastectomies, increased contralateral prophylactic mastectomies, increased work-ups, and delay to definitive surgery. In summary, the routine use of pre-operative breast MRI is not warranted for the typical patient with a newly diagnosed early stage breast cancer.

  13. Breast cancer management: Past, present and evolving

    2012-01-01

    Full Text Available Breast cancer is known from ancient time,and the treatment strategy evolved as our understanding of the disease changed with time. In 460 BC Hippocrates described breast cancer as a humoral disease and presently after a lot of studies breast cancer is considered as a local disease with systemic roots. For most of the twentieth century Halsted radical mastectomy was the "established and standardized operation for cancer of the breast in all stages, early or late". New information about tumor biology and its behavior suggested that less radical surgery might be just as effective as the more extensive one. Eventually, with the use of adjuvant therapy likeradiation and systemic therapy, the extent of surgical resection in the breast and axilla got reduced further and led to an era of breast conservation. The radiation treatment of breast cancer has evolved from 2D to 3D Conformal and to accelarated partial breast irradiation, aiming to reduce normal tissue toxicity and overall treatment time. Systemic therapy in the form of hormone therapy, chemotherapy and biological agents is now a well-established modality in treatment of breast cancer. The current perspective of breast cancer management is based on the rapidly evolving and increasingly integrated study on the genetic, molecular , biochemical and cellular basis of disease. The challenge for the future is to take advantage of this knowledge for the prediction of therapeutic outcome and develop therapies and rapidly apply more novel biologic therapeutics.

    Full Text Available Ectopic or accessory breast tissue is most commonly located in the axilla, though it may be present anywhere along the milk line. Development is hormone dependent, similar to normal breast tissue. These lesions do not warrant any intervention unless they produce discomfort, thus their identification and distinction from other breast pathologies, both benign and malignant, is essential. We report a case with locally advanced breast cancer who presented with an ipsilateral axillary mass following surgery, radiotherapy, and chemotherapy. Subsequent evaluation with excision biopsy showed duct ectasia in axillary breast tissue and the patient was continued on hormone therapy with tamoxifen.

    Treatment options as well as the characteristics for therapeutic decisions in patients with primary and advanced breast cancer are increasing in number and variety. New targeted therapies in combination with established chemotherapy schemes are broadening the spectrum, however potentially promising combinations do not always achieve a better result. New data from the field of pharmacogenomics point to prognostic and predictive factors that take not only the properties of the tumour but also inherited genetic properties of the patient into consideration. Current therapeutic decision-making is thus based on a combination of classical clinical and modern molecular biomarkers. Also health-economic aspects are more frequently being taken into consideration so that health-economic considerations may also play a part. This review is based on information from the recent annual congresses. The latest of these are the 34th San Antonio Breast Cancer Symposium 2011 and the ASCO Annual Meeting 2012. Among their highlights are the clinically significant results from the CLEOPATRA, BOLERO-2, EMILIA and SWOG S0226 trials on the therapy for metastatic breast cancer as well as further state-of-the-art data on the adjuvant use of bisphosphonates within the framework of the ABCSG-12, ZO-FAST, NSABP-B34 and GAIN trials.

  16. [THE EFFECT OF PREGNANCY ON BREAST CANCER].

    2015-08-01

    Cancer and pregnancy coincide in about one in 1,000 pregnancies. One of the most common malignancies associated with pregnancy is breast cancer. Women with pregnancy-associated breast cancer (PABC) have a higher likelihood of being diagnosed with metastatic disease and estrogen receptor (ER) negative tumors than do non-pregnant women. Controversies exist regarding the effect of pregnancy on breast cancer prognosis. Some researchers suggest that pregnancy does not affect breast cancer prognosis, whereas others claim the opposite. Although PABC is usually discovered in an advanced stage, breast cancer metastasis on the placenta is a rare event. During cancer progression, the surrounding microenvironment co-evolves into an activated state through continuous communication with the malignant cells, thereby promoting tumor growth. The effect of pregnancy and placental environment on breast cancer biology is the issue of this review. Placental and cancer cells implantation processes share similar molecular pathways. This suggests that placental factors may affect breast cancer cells biology. Previously, we analyzed the effect of first trimester human placenta on breast cancer cells. Breast cancer cells were co-cultured with placental explants during their implantation on matrigel substrate. We found that the placenta reduced ER expression on the cancer cells and induced their migration and invasion abilities. As a result of it, breast cancer cells migrated away from the placental implantation sites. Hormonal pathways were involved in these phenomena. These results may explain the high incidence of metastases during pregnancy in on the one hand and the rarity of metastases on the placenta on the other hand.

    Full Text Available Steven Lehrer, Sheryl Green, John A Martignetti, Kenneth E Rosenzweig Departments of Radiation Oncology and Genetics and Genomic Sciences, Icahn School of Medicine at Mount Sinai, New York, NY, USA Background: The risk of thyroid cancer is known to be slightly increased in women after treatment for breast cancer. In the current study, we analyzed the incidence of thyroid cancer and breast cancer in 50 US states and in the District of Columbia to ascertain how often these two diseases are associated. Methods: Data on the incidence of thyroid cancer were obtained from the Centers for Disease Control and Prevention and the National Cancer Institute and data on the incidence of breast cancer were from the American Cancer Society. Data on the average number of children per family with children and mean household income were sourced from the US Bureau of the Census and prevalence of obesity by state is determined from a paper published in 2010 on state-specific obesity prevalence among US adults by the Centers for Disease Control and Prevention. Results: There was a significant association between breast and thyroid cancer (P=0.002. Since the incidence of breast cancer increases with increasing income and obesity, while decreasing with parity, multiple linear regression was performed. Breast cancer incidence was significantly related to thyroid cancer incidence (β=0.271, P=0.039, inversely related to average number of children per family with children (β=-0.271, P=0.039, unrelated to adult obesity (β=0.134, P=0.369, and significantly related to family income (β=0.642, P<0.001. Conclusion: This study identifies an association between breast and thyroid cancer. The association suggests that unexplored breast-thyroid cancer susceptibility loci exist and warrant further study.

    Breast cancer is the leading cause of cancer among women worldwide and the most common cancer in China. Many factors influence the treatment strategy for metastatic breast cancer (MBC). Chemotherapy should be administered to patients with hormone receptor-negative tumors, symptomatic visceral metastasis, and a short disease-free interval. Sequential single-agent chemotherapy has similar efficacy as combination agents in terms of overall survival and quality of life. Anthracyclines are the cornerstone of first-line treatment for MBC, and taxanes represent the second treatment option after resistance. When progression or intolerable toxicity occurs after optimal treatment, the alternative treatments include capecitabine, vinorel-bine, and gemcitabine. Ixabepilone and eribulin are relatively new effective single agents. A combination of cytotoxic agents for patients with rapid clinical progression can further improve the overall response rate and time to progression compared to single-agent treatment. For patients with MBC who were pretreated with anthracyclines in the neoadjuvant/adjuvant setting, a taxane-containing regimen such as docetaxel plus capecitabine or gemcitabine plus paclitaxel should be administered. Platinum-based therapies such as cisplatin or carboplatin have a role in the treatment of triple-negative breast cancer. Meanwhile, the efficacy of the addition of targeted drugs such as iniparib, bevacizumab, and cetuximab to chemotherapy remains unproven. Maintenance chemotherapy is routinely recommended in clinical practice at present. Patients who were previously treated with paclitaxel and gemcitabine have better progression-free and overall survival with maintenance chemotherapy according to a Korean phase Ⅲ clinical trial. Sequential maintenance treatment with capecitabine monotherapy after capecitabine-based combination chemotherapy (X-based X) appears favorable based on a series of domestic studies.

    biological functions of TIMP-1 such as growth-stimulating functions, as well as anti-apoptotic and pro-angiogenetic effects, may in part explain this paradox. The purpose of this review is to give an update on the current status of TIMP-1 in breast cancer, emphasizing the prognostic utility of the inhibitor......Whether patients diagnosed with primary breast cancer are offered adjuvant systemic therapy following surgical removal of the tumor is based on prognosis. Prognosis is estimated in every patient using established prognostic variables. Unfortunately, when using the currently available prognostic...... parameters a significant proportion of patients are over-treated. Thus, in order to improve stratification of breast cancer patients, additional prognostic factors need to be identified.

    Hormonal dependent breast cancer is a heterogeneous disease from a molecular and clinical perspective. The relapse risk of early breast cancer patients treated with adjuvant hormonal therapy varies. Validated predictive markers concerning adjuvant cytotoxic treatment are still lacking in ER+/ HER2-  breast cancer, which has a good prognosis in general. This can lead to the inefficient chemotherapy indication. Molecular classification of breast cancer reports evidence about the heterogeneity of hormonal dependent breast cancer and its stratification to different groups with different characteristics. Multigene assays work on the molecular level, and their aim is to provide patients risk stratification and therapy efficacy prediction. The position of multigene assays in clinical practice is not stabile yet. Non uniform level of evidence connected to patients prognosis interpretations and difficult comparison of tests are the key problems, which prevent their wide clinical use. The article is a summary of some of the most important multigene assays in breast cancer and their current position in oncology practice.

  4. Apoptotic effect of noscapine in breast cancer cell lines.

    Quisbert-Valenzuela, Edwin O; Calaf, Gloria M

    2016-06-01

    Cancer is a public health problem in the world and breast cancer is the most frequently cancer in women. Approximately 15% of the breast cancers are triple-negative. Apoptosis regulates normal growth, homeostasis, development, embryogenesis and appropriate strategy to treat cancer. Bax is a protein pro-apoptotic enhancer of apoptosis in contrast to Bcl-2 with antiapoptotic properties. Initiator caspase-9 and caspase-8 are features of intrinsic and extrinsic apoptosis pathway, respectively. NF-κB is a transcription factor known to be involved in the initiation and progression of breast cancer. Noscapine, an alkaloid derived from opium is used as antitussive and showed antitumor properties that induced apoptosis in cancer cell lines. The aim of the present study was to determine the apoptotic effect of noscapine in breast cancer cell lines compared to breast normal cell line. Three cell lines were used: i) a control breast cell line MCF-10F; ii) a luminal-like adenocarcinoma triple-positive breast cell line MCF-7; iii) breast cancer triple-negative cell line MDA-MB-231. Our results showed that noscapine had lower toxicity in normal cells and was an effective anticancer agent that induced apoptosis in breast cancer cells because it increases Bax gene and protein expression in three cell lines, while decreases Bcl-xL gene expression, and Bcl-2 protein expression decreased in breast cancer cell lines. Therefore, Bax/Bcl-2 ratio increased in the three cell lines. This drug increased caspase-9 gene expression in breast cancer cell lines and caspase-8 gene expression increased in MCF-10F and MDA-MB-231. Furthermore, it increased cleavage of caspase-8, suggesting that noscapine-induced apoptosis is probably due to the involvement of extrinsic and intrinsic apoptosis pathways. Antiapoptotic gene and protein expression diminished and proapoptotic gene and protein expression increased noscapine-induced expression, probably due to decrease in NF-κB gene and protein expression

    Murakami, Masao [Tenri Hospital, Nara (Japan)

    2000-10-01

    This paper summarizes the treatment of locally advanced breast cancer, inflammatory breast cancer, and locally recurrent breast cancer. A multidisciplinary approach considering subclinical distant metastases is needed to treat these types of breast cancer. Subclinical distant metastasis is observed in about 80% of case of locally advanced cancer, and treatment of subclinical distant metastases, e.g., by endocrinotherapy and chemotherapy, is therefore essential to improving the prognosis. The standard therapy for unresectable locally advanced breast cancer consists of induction chemotherapy with anthracyclines and local treatment with mastectomy or irradiation. Previous reports have stated that induction chemotherapy was effective in 60-80% of the primary lesions or lymph node metastasis, and the CR rates were in the 10-20% range. Combination therapy with induction chemotherapy clearly improved the outcome over local treatment alone. The usual irradiation dose is 50 to 60 Gy/5 to 7 weeks to the whole breast or the thoracic wall. Boost irradiation at a dose of 10 to 25 Gy is performed in unresectable cases. The boost irradiation dose to the lymph node area is usually 45 to 50 Gy/5 to 6 weeks in cases without gross lesions and 10 to 15 Gy in cases with gross lesions. Combination therapy consisting of conservative pectoral mastectomy and postoperative adjuvant chemo- endocrino-therapy (i.e., adjuvant therapy) has become the standard regimen for treating resectable locally advanced breast cancer, because it significantly improves the recurrence rate and survival rate compared to local treatment alone. Some clinical have studies indicated that neoadjuvant therapy (i.e., induction chemotherapy + surgery/radiation therapy) is comparable or superior to adjuvant therapy in terms of improving the prognosis. However, the efficacy and most appropriate method of breast-conserving therapy after induction chemotherapy are still unclear. More clinical trials are needed. It has been

    2016-09-01

    We evaluated individual grain-containing foods and whole and refined grain intake during adolescence, early adulthood, and premenopausal years in relation to breast cancer risk in the Nurses' Health Study II. Grain-containing food intakes were reported on a baseline dietary questionnaire (1991) and every 4 years thereafter. Among 90,516 premenopausal women aged 27-44 years, we prospectively identified 3235 invasive breast cancer cases during follow-up to 2013. 44,263 women reported their diet during high school, and from 1998 to 2013, 1347 breast cancer cases were identified among these women. Cox proportional hazards regression was used to estimate relative risks (RR) and 95 % confidence intervals (95 % CI) of breast cancer for individual, whole and refined grain foods. After adjusting for known breast cancer risk factors, adult intake of whole grain foods was associated with lower premenopausal breast cancer risk (highest vs. lowest quintile: RR 0.82; 95 % CI 0.70-0.97; P trend = 0.03), but not postmenopausal breast cancer. This association was no longer significant after further adjustment for fiber intake. The average of adolescent and early adulthood whole grain food intake was suggestively associated with lower premenopausal breast cancer risk (highest vs lowest quintile: RR 0.74; 95 % CI 0.56-0.99; P trend = 0.09). Total refined grain food intake was not associated with risk of breast cancer. Most individual grain-containing foods were not associated with breast cancer risk. The exceptions were adult brown rice which was associated with lower risk of overall and premenopausal breast cancer (for each 2 servings/week: RR 0.94; 95 % CI 0.89-0.99 and RR 0.91; 95 % CI 0.85-0.99, respectively) and adult white bread intake which was associated with increased overall breast cancer risk (for each 2 servings/week: RR 1.02; 95 % CI 1.01-1.04), as well as breast cancer before and after menopause. Further, pasta intake was inversely associated with

    Full Text Available The response of single breast cancer cells (cell line T‐47D to 17β‐estradiol (E2 under different concentrations was studied by using an instrument that allows to combine far‐field light microscopy with high resolution scanning near‐field (AFM/SNOM microscopy on the same cell. Different concentrations of E2 induce clearly different effects as well on cellular shape (in classical bright‐field imaging as on surface topography (atomic force imaging and absorbance (near‐field light transmission imaging. The differences range from a polygonal shape at zero via a roughly spherical shape at physiological up to a spindle‐like shape at un‐physiologically high concentrations. The surface topography of untreated control cells was found to be regular and smooth with small overall height modulations. At physiological E2 concentrations the surfaces became increasingly jagged as detected by an increase in membrane height. After application of the un‐physiological high E2 concentration the cell surface structures appeared to be smoother again with an irregular fine structure. The general behaviour of dose dependent differences was also found in the near‐field light transmission images. In order to quantify the treatment effects, line scans through the normalised topography images were drawn and a rate of co‐localisation between high topography and high transmission areas was calculated. The cell biological aspects of these observations are, so far, not studied in detail but measurements on single cells offer new perspectives to be empirically used in diagnosis and therapy control of breast cancers.

    2016-01-01

    Male breast cancer (MBC) is an uncommon and poorly understood disease. Recent molecular studies have shown important differences from female breast cancer which are likely to influence treatment strategies from the current female-based management towards a more tailored approach. Significantly more MBCs than female breast cancers arise with an underlying germline cancer predisposition, and display a vastly different penetrance compared with females. Furthermore, the genophenotypical association of basal-like cancer with BRCA1 present in female breast cancer is not observed in male breast cancer. Differences in somatic changes between male and female breast cancer have also been reported, with particular enrichment of PIK3CA mutations and a paucity of TP53 mutations. In general, chromosomal-based changes, in particular regions of gains, are seen more frequently in male than female breast cancer and methylation is seen less frequently. Clinically, several molecular subtypes with prognostic relevance have been described, including chromosomal complex high and methylation high groups, and subgroups with profiling signatures pertaining to epithelial mesenchymal transition and hormonal therapy insensitivity. As with female breast cancer, attention to male specific multicentre trials based on the individual characteristics are needed, together with establishment of reliable preclinical models to understand more clearly the pathogenesis of male breast cancer and improve the general poor outcome of this disease.

  12. Interleukin-8 in breast cancer progression.

    Todorović-Raković, Nataša; Milovanović, Jelena

    2013-10-01

    Interleukin-8 (IL-8) is a chemokine that has an autocrine and/or paracrine tumor-promoting role and significant potential as a prognostic and/or predictive cancer biomarker. In breast cancer, which is mostly determined by expression of estrogen receptor (ER) and human epidermal growth factor receptor 2 (HER2), IL-8 could play a specific role. IL-8 is highly expressed in ER- breast cancers, but it increases invasiveness and metastatic potential of both ER- and ER+ breast cancer cells. It is also highly expressed in HER2+ breast cancers. Because of the complex crosstalk between these receptors and IL-8, its role is mainly determined by delicate balance in their signaling pathways. Therefore, the main point of this review was to analyze the possible influence of IL-8 in breast cancer progression related to its interaction with ER and HER2 and the consequent therapeutic implications of these relations.

    Because cancer of the male breast is rare knowledge about its biology and behavior is essentially due to a compilation of pooled experiences. Hence, a continued report of cases appears to be important. Therefore a retrospective review of patients suffering from male breast cancer was carried out. Twenty-four evaluable cases were analyzed. Eight patients (1 patient with bilateral Stage I carcinoma was included) were in Stage I, 7 in Stage II, 2 in Stage IIIa, 4 in Stage IIIb, and 3 in Stage IV. Of 23 patients who were treated with mastectomy, 22 had modified radical mastectomy and postoperative irradiation to the chest wall as well as to the peripheral lymphatic areas in most cases. One patient underwent radical mastectomy. Another patient had an excision biopsy only, followed by irradiation. One of 24 patients received tamoxifen; another received cyclophosphamide, methotrexate, 5-fluorouracil, prednisone (CMF) regimen in an adjuvant setting. Local recurrence developed in one of 23 (4%) patients treated with mastectomy and radiation therapy to the chest wall and peripheral lymphatics. Four (17%) patients developed distant metastases. The 5-year overall survival (Kaplan-Maier) was 90% for the entire group, 100% for patients in Stage I-III disease, and 60% in Stage IV disease (P = < 0.005). As observed in former reports the stage of disease at initial presentation seems to be a parameter that significantly contributes to survival in male breast cancer patients. To what extent improved local control by adequate local therapy, such as surgery and postoperative radiotherapy, may improve overall survival remains to be discussed. (orig.)

  1. Field cancerization in mammary carcinogenesis - Implications for prevention and treatment of breast cancer.

    Science.gov (United States)

    Rivenbark, Ashley G; Coleman, William B

    2012-12-01

    The natural history of breast cancer unfolds with the development of ductal carcinoma in situ (DCIS) in normal breast tissue, and evolution of this pre-invasive neoplasm into invasive cancer. The mechanisms that drive these processes are poorly understood, but evidence from the literature suggests that mammary carcinogenesis may occur through the process of field cancerization. Clinical observations are consistent with the idea that (i) DCIS may arise in a field of altered breast epithelium, (ii) narrow surgical margins do not remove the entire altered field (contributing to recurrence and/or disease progression), and (iii) whole-breast radiation therapy is effective in elimination of the residual field of altered cells adjacent to the resected DCIS. Molecular studies suggest that the field of altered breast epithelial cells may carry cancer-promoting genetic mutations (or other molecular alterations) or cancer promoting epimutations (oncogenic alterations in the epigenome). In fact, most breast cancers develop through a succession of molecular events involving both genetic mutations and epimutations. Hence, in hereditary forms of breast cancer, the altered field reflects the entire breast tissue which is composed of cells with a predisposing molecular lesion (such as a BRCA1 mutation). In the example of a BRCA1-mutant patient, it is evident that local resection of a DCIS lesion or localized but invasive cancer will not result in elimination of the altered field. In sporadic breast cancer patients, the mechanistic basis for the altered field may not be so easily recognized. Nonetheless, identification of the nature of field cancerization in a given patient may guide clinical intervention. Thus, patients with DCIS that develops in response to an epigenetic lesion (such as a hypermethylation defect affecting the expression of tumor suppressor genes) might be treated with epigenetic therapy to normalize the altered field and reduce the risk of secondary occurrence of

    2015-01-01

    Full Text Available Morphine is considered a highly potent analgesic agent used to relieve suffering of patients with cancer. Several in vitro and in vivo studies showed that morphine also modulates angiogenesis and regulates tumour cell growth. Unfortunately, the results obtained by these studies are still contradictory. In order to better dissect the role of morphine in cancer cell growth and angiogenesis we performed in vitro studies on ER-negative human breast carcinoma cells, MDA.MB231 and in vivo studies on heterotopic mouse model of human triple negative breast cancer, TNBC. We demonstrated that morphine in vitro enhanced the proliferation and inhibited the apoptosis of MDA.MB231 cells. In vivo studies performed on xenograft mouse model of TNBC revealed that tumours of mice treated with morphine were larger than those observed in other groups. Moreover, morphine was able to enhance the neoangiogenesis. Our data showed that morphine at clinical relevant doses promotes angiogenesis and increases breast cancer progression.

    Despite the initial benefits of treating HER2-amplified breast cancer patients with the tyrosine kinase inhibitor lapatinib, resistance inevitably develops. Here we report that lapatinib induces the degradation of the nuclear receptor ERRα, a master regulator of cellular metabolism, and that the expression of ERRα is restored in lapatinib-resistant breast cancer cells through reactivation of mTOR signalling. Re-expression of ERRα in resistant cells triggers metabolic adaptations favouring mitochondrial energy metabolism through increased glutamine metabolism, as well as ROS detoxification required for cell survival under therapeutic stress conditions. An ERRα inverse agonist counteracts these metabolic adaptations and overcomes lapatinib resistance in a HER2-induced mammary tumour mouse model. This work reveals a molecular mechanism by which ERRα-induced metabolic reprogramming promotes survival of lapatinib-resistant cancer cells and demonstrates the potential of ERRα inhibition as an effective adjuvant therapy in poor outcome HER2-positive breast cancer.

    1988-08-01

    A prognostic classification for thermographic staging of breast cancer has been applied to a cohort of 70 patients from 5040 screenees enrolled in the Albert Einstein Medical Center (AEMC) Breast Cancer Detection Demonstration Project (BCDDP). A diagnosis of breast cancer was established in each case before December 31, 1980. None of the patients have been lost to follow-up which extended from a minimum of 6 to a maximum of 13 years. Survival rates for those with favorable, equivocal, and poor thermographic factors are compared with each other and with results in accordance with tumor-node-metastasis (TNM) classification. As of December 31, 1986, there have been 22 (31.4%) deaths, all attributed to breast cancer. The thermographic scoring system clearly shows shorter survival for patients with poor thermographic prognostic factors, 30% surviving at 5 years and only 20% at 10 years compared with overall survival of 80% at 5 years and 70% at 10 years.

  15. The potential role of breast ductoscopy in breast cancer screening.

    2005-01-01

    Breast cancer remains the most common malignancy among women in the Western world. Mammography, which is currently the main screening modality for early detection, has a low positive predictive value of only 25%, especially in young women with very dense breasts. Therefore, new screening approaches are needed for the early detection of breast cancer in all age groups. Mammary ductoscopy (MD) is a newly developed endoscopic technique that allows direct visualization and biopsy of the mammary ductal epithelium where most cancers originate. The procedure can be performed under local anesthesia in the office setting. At present, MD is used as a diagnostic adjunct in patients with pathological nipple discharge and to guide duct excision surgery. This article focuses on the potential of this technique in breast cancer screening and highlights its limitations in this context.

    Purpose: Exercise decreases breast cancer risk and disease recurrence, but the underlying mechanisms are unknown. Training adaptations in systemic factors have been suggested as mediating causes. We aimed to examine if systemic adaptations to training over time, or acute exercise responses......, in breast cancer survivors could regulate breast cancer cell viability in vitro. Methods: Blood samples were collected from breast cancer survivors, partaking in either a 6-month training intervention or across a 2 h acute exercise session. Changes in training parameters and systemic factors were evaluated...... and pre/post exercise-conditioned sera from both studies were used to stimulate breast cancer cell lines (MCF-7, MDA-MB-231) in vitro. Results: Six months of training increased VO2peak (16.4 %, p

    Papa, V; Costantino, A; Belfiore, A

    1997-10-01

    It is commonly believed that the insulin receptor mainly mediates the metabolic effects of insulin, whereas the closely related IGF-I receptor is considered a major factor for the regulation of cell proliferation. Experimental and epidemiological evidence indicates, however, that insulin and insulin receptors may play an important role in breast cancer. This article reviews evidence indicating that (a) insulin receptors are overexpressed in human breast cancer, (b) insulin stimulates growth in breast cancer cells, (c) cells transfected with human insulin receptor may acquire a ligand-dependent transformed phenotype, and (d) breast cancer is associated with insulin resistance and hyperinsulinemia. These findings may open new possibilities in breast cancer prevention, prognosis assessment, and therapy. (Trends Endocrinol Metab 1997; 8:306-312). (c) 1997, Elsevier Science Inc.

    BACKGROUND: A variety of estimates of the benefits and harms of mammographic screening for breast cancer have been published and national policies vary. OBJECTIVES: To assess the effect of screening for breast cancer with mammography on mortality and morbidity. SEARCH STRATEGY: We searched Pub...... excluded a biased trial and included 600,000 women in the analyses. Three trials with adequate randomisation did not show a significant reduction in breast cancer mortality at 13 years (relative risk (RR) 0.90, 95% confidence interval (CI) 0.79 to 1.02); four trials with suboptimal randomisation showed...... a significant reduction in breast cancer mortality with an RR of 0.75 (95% CI 0.67 to 0.83). The RR for all seven trials combined was 0.81 (95% CI 0.74 to 0.87). We found that breast cancer mortality was an unreliable outcome that was biased in favour of screening, mainly because of differential...

  20. Role of KCNMA1 in breast cancer.

    Full Text Available KCNMA1 encodes the α-subunit of the large conductance, voltage and Ca(2+-activated (BK potassium channel and has been reported as a target gene of genomic amplification at 10q22 in prostate cancer. To investigate the prevalence of the amplification in other human cancers, the copy number of KCNMA1 was analyzed by fluorescence-in-situ-hybridization (FISH in 2,445 tumors across 118 different tumor types. Amplification of KCNMA1 was restricted to a small but distinct fraction of breast, ovarian and endometrial cancer with the highest prevalence in invasive ductal breast cancers and serous carcinoma of ovary and endometrium (3-7%. We performed an extensive analysis on breast cancer tissue microarrays (TMA of 1,200 tumors linked to prognosis. KCNMA1 amplification was significantly associated with high tumor stage, high grade, high tumor cell proliferation, and poor prognosis. Immunofluorescence revealed moderate or strong KCNMA1 protein expression in 8 out of 9 human breast cancers and in the breast cancer cell line MFM223. KCNMA1-function in breast cancer cell lines was confirmed by whole-cell patch clamp recordings and proliferation assays, using siRNA-knockdown, BK channel activators such as 17ß-estradiol and the BK-channel blocker paxilline. Our findings revealed that enhanced expression of KCNMA1 correlates with and contributes to high proliferation rate and malignancy of breast cancer.

    Cadmium is a known human lung carcinogen, although some studies indicate a link between cadmium exposure and human breast cancer. The objective of this study was to assess cadmium concentration in breast tissue samples of patients with breast cancer and benign breast tumor. MATERIAL AND METHODS. The concentration of cadmium was determined in breast tissue samples of 21 breast cancer and 19 benign tumor patients. Two samples of breast tissue from each patient, i.e. tumor and normal tissue close to tumor, were taken for the analysis. Cadmium was determined by atomic absorption spectrometry (Perkin-Elmer, Zeeman 3030). RESULTS. In patients with breast cancer, the mean cadmium concentration was 33.1 ng/g (95% CI, 21.9-44.4) in malignant breast tissue and 10.4 ng/g (95% CI, 5.6-15.2) in normal breast tissue (P=0.002). In patients with benign tumor, the corresponding values were 17.5 ng/g (95% CI, 8.4-26.5) and 11.8 ng/g (95% CI, 5.1-18.5) (P=0.3144). There was a statistically significant difference in cadmium concentration between malignant and benign breast tissues (P=0.009). CONCLUSION. The data obtained show that cadmium concentration is significantly higher in malignant breast tissue as compared with normal breast tissue of the same women or benign breast tissue. Further studies are necessary to determine the association between cadmium concentration in malignant breast tissue and estrogen receptor level, and smoking.

    Our goal was to design a prone breast shield for the contralateral breast and study its efficacy in decreasing scatter radiation to the contralateral breast in a prone breast phantom setup receiving radiation therapy designed for breast cancer. We constructed a prone breast phantom setup consisting of (1) A thermoplastic mask with a left-sided depression created by a water balloon for a breast shape; (2) 2 plastic bags to hold water in the thermoplastic mask depression; (3) 2000 mL of water to fill the thermoplastic mask depression to create a water-based false breast; (4) 1-cm thick bolus placed in the contralateral breast holder; (5) 2 lead (Pb) sheets, each 0.1-cm thick for blocking scatter radiation in the contralateral bolus-based false breast; (6) a prone breast board to hold the thermoplastic mask, water, bolus, and lead; (7) 9 cm solid water on top of the breast board to simulate body; (8) a diode was used to verify dose for each treatment field of the treated water-based breast; (9) metal–oxide–semiconductor-field effect transistor (MOSFET) dosimeters to measure dose to the contralateral bolus-based breast. The phantom prone breast setup was CT simulated and treatment was designed with 95% isodose line covering the treated breast. The maximum dose was 107.1%. Megavoltage (MV) port images ensured accurate setup. Measurements were done using diodes on the treated water-based breast and MOSFET dosimeters at the medial and lateral sides of the contralateral bolus-based breast without and with the Pb shield. Five treatments were done for each of the 3 data sets and recorded individually for statistical purposes. All treatments were completed with 6 MV photons at 200 cGy per treatment. The dose contributions from each of the 3 data sets including 15 treatments total without and with the prone lead shield to the medial and lateral portions of contralateral bolus-based breast were averaged individually. Unshielded dose means were 37.11 and 2.94 cGy, and

    2012-04-01

    Full Text Available Introduction: Breast cancer is the most common cancer in women, and if diagnosed on time, the chance of treatment will increase. There is limited information about the knowledge and practice of Iranian women about early detection of breast cancer and in this study we aimed to investigate it in Kerman. Methods: This was a cross-sectional study done on 120 women; from 6 randomly selected maternal and childcare centers spread around Kerman, women were questioned about the primary signs of breast cancer and the screening methods. Results: The results show that 70% of women thought that with on time detection, breast cancer can be successfully treated, but 47% had no idea about any screening method. The most common breast cancer sign mentioned by women was a painless lump. Breast self examination as the easiest and cheapest screening method was never done in 51% of women. The most common reason for not performing screening tests in the participants, was not knowing anything about it. Conclusion: Although breast cancer when diagnosed on time is treatable, the knowledge and attitude of Iranian women about breast cancer screening and the signs of breast cancer are very low. Educational programs to increase women's knowledge about breast cancer should be foreseen and performed

    Women who develop bilateral breast cancer at an early age are likely to harbour germline mutations in breast cancer susceptibility genes. The aim of this study was to test for concordant genetic changes in left and right breast cancer of young women (age < 50) with bilateral breast cancer that may suggest an inherited breast cancer predisposition. Microsatellite markers were used to test for loss of heterozygosity (LOH) in left and right tumours for 31 women with premenopausal bilateral breast cancer. Markers adjacent to or within candidate genes on 17p (p53), 17q (BRCA1), 13q (BRCA2), 11q (Ataxia Telangiectasia-ATM) and 3p (FHIT) were chosen. Mutational testing for BRCA1 and BRCA2 was performed for cases where blood was available. Concordant LOH in both left and right tumours was demonstrated for at least one of the markers tested in 16/31(54%) cases. Where allelic loss was demonstrated for both left and right breast cancer, the same allele was lost on each occasion. This may suggest a common mutational event. Four cases showed concordant loss of alleles in both left and right breast cancer at D17S791 (BRCA1). BRCA1 mutations were identified in two of these cases where blood was available. Four cases showed concordant LOH at D13S155 (BRCA2). Concordant LOH was further demonstrated in seven cases for D11S1778 (ATM) and four cases for D3S1300 (which maps to the FHIT gene), suggesting a possible role for these tumour suppressor genes in this subgroup of breast cancer patients. No concordant allelic loss was demonstrated for D17S786 suggesting that germline mutations in p53 are unlikely in such cases of bilateral breast cancer.

    Male breast cancer (male BC) accounts for Klinefelter syndrome) and a positive family history for breast cancer. About 90% of male BC are invasive ductal carcinomas. Standard treatment for localized cancer is surgical removal. Adjuvant radiation and systemic therapy are the same as in women with breast cancer. Male BC expresses hormone receptors in about 90% of cases; therefore, tamoxifen is a therapeutic option. A future challenge for the urologist or andrologist is to diagnose the disease at an early stage to improve prognosis.

    Purpose: Postoperative radiotherapy decreases breast cancer mortality. However, studies have revealed a long-lasting breast pain among some women after radiotherapy. The purpose of this study was to identify risk factors that contribute to breast pain after breast cancer radiotherapy. Methods and Materials: We identified 1,027 recurrence-free women in two cohorts of Swedish women treated for breast cancer. The women had breast-conserving surgery and postoperative radiotherapy, the breast was treated to 48 Gy in 2.4-Gy fractions or to 50 Gy in 2.0-Gy fractions. Young women received a boost of up to 16 Gy. Women with more than three lymph node metastases had locoregional radiotherapy. Systemic treatments were given according to health-care guidelines. Three to 17 years after radiotherapy, we collected data using a study-specific questionnaire. We investigated the relation between breast pain and potential risk modifiers: age at treatment, time since treatment, chemotherapy, photon energy, fractionation size, boost, loco-regional radiotherapy, axillary surgery, overweight, and smoking. Results: Eight hundred seventy-seven women (85%) returned the questionnaires. Among women up to 39 years of age at treatment, 23.1% had breast pain, compared with 8.7% among women older than 60 years (RR 2.66; 95% CI 1.33-5.36). Higher age at treatment (RR 0.96; 95% CI 0.94-0.98, annual decrease) and longer time since treatment (RR 0.93; 95% CI 0.88-0.98, annual decrease) were related to a lower occurrence of breast pain. Chemotherapy increased the occurrence of breast pain (RR 1.72; 95% CI 1.19-2.47). In the multivariable model only age and time since treatment were statistically significantly related to the occurrence of breast pain. We found no statistically significant relation between breast pain and the other potential risk modifiers. Conclusions: Younger women having undergone breast-conserving surgery with postoperative radiotherapy report a higher occurrence of long

  17. Breast cancer and possible mechanisms of therapy resistance

    Directory of Open Access Journals (Sweden)

    Ana-Maria Florea

    2013-03-01

    Full Text Available Breast cancer represents one of the most common cancers in women and is a major life threatening illness found all over the world. Therapy approaches include irradiation and surgery, with chemotherapy considered an important strategy to treat breast cancer. Platinum based anticancer drugs, such as cisplatin (cis-di-amino-dichloride-platin, CDDP, carboplatin, orthoplatin, etc., have been successfully used in breast cancer therapy because they activate multiple mechanisms to induce apoptosis in tumor cells. Nevertheless, during chemotherapy, drug resistance frequently develops; this impairs the successful treatment of breast cancer and often leads to patients’ decease. While combinations of anticancer drugs used in chemotherapy regimens reduced the occurrence of drug resistance (e.g. doxorubicin + docetaxel, doxorubicin + cyclophosphamide, docetaxel + herceptin + carboplatin the molecular mechanism of those effects are not completely understood. Here we review possible mechanisms related to breast cancer treatment and resistance to current therapies as well as possible new therapeutic targets (e.g. calcium signaling which could be used in the future.

    Breast MRI is being used more frequently for advanced screening for breast cancer. Patients may be at increased risk, or are symptomatic, with nonsuspicious mammograms. There is little data regarding the likelihood of a recommendation for biopsy, or for detecting a malignancy, in this population. We intended to determine the malignancy rate, number needed to treat, and positive predictive value for patients receiving adjunctive MRI at our institution. A retrospective review of all breast MRIs from 2008 to 2010 was done. Patients with any prior diagnosis of breast cancer, or BRCA+ were excluded. There were 324 patients. Most common reasons for ordering the breast MRI included: abnormal test result 130 (44%), palpable mass 74 (23%), family history 58 (18%), breast pain 47 (15%), and nipple discharge 45 (14%). Breast Imaging-Reporting and Data System score (BIRADS) was 1 or 2 in 36 per cent, 4 or 5 in 18 per cent, 3 in 26 per cent, 0 in 10 per cent, and not given in 9 per cent. Biopsy was recommended in 77 (24%), with biopsy actually performed in 57 (18%). Of the eight cancers identified, four (1.2%) were ductal carcinoma in situ (DCIS) and four (1.2%) were invasive cancer, yielding a true-positive rate of 2.5 per cent. Number needed to treat was 40. Positive predictive value was 14 per cent with a false-positive rate of 86 per cent. In this group of generally higher risk women, typically prescreened with mammography, 1.2 per cent had an invasive cancer, and another 1.2 per cent had DCIS. Those who undergo biopsy are 6.1 times more likely to have benign pathology. The efficacy of adjunctive breast MRI could be improved through refinements in indication, test interpretation, or alternative screening strategies.

    2016-01-01

    Objective To offer FPs a summary of evidence-based recommendations to guide their follow-up survivorship care of women treated for breast cancer. Quality of evidence A literature search was conducted in MEDLINE from 2000 to 2016 using the search words breast cancer, survivorship, follow-up care, aftercare, guidelines, and survivorship care plans, with a focus on review of recent guidelines published by national cancer organizations. Evidence ranges from level I to level III. Main message Survivorship care involves 4 main tasks: surveillance and screening, management of long-term effects, health promotion, and care coordination. Surveillance for recurrence involves only annual mammography, and screening for other cancers should be done according to population guidelines. Management of the long-term effects of cancer and its treatment addresses common issues of pain, fatigue, lymphedema, distress, and medication side effects, as well as longer-term concerns for cardiac and bone health. Health promotion emphasizes the benefits of active lifestyle change in cancer survivors, with an emphasis on physical activity. Survivorship care is enhanced by the involvement of various health professionals and services, and FPs play an important role in care coordination. Conclusion Family physicians are increasingly the main providers of follow-up care after breast cancer treatment. Breast cancer should be viewed as a chronic medical condition even in women who remain disease free, and patients benefit from the approach afforded other chronic conditions in primary care.

    Full Text Available This is a literature review on the aetiology and pathogenesis of breast cancer, which is the most common cancer worldwide, and the second leading cause of cancer death, especially in Western countries. Several aetiological factors have been implicated in its pathogenesis, and include age, genetics, family history, diet, alcohol, obesity, lifestyle, physical inactivity, as well as endocrine factors. These factors act separately or together in the causation of breast cancer. More recently, triple negative breast cancer has been described in certain categories of patients and is associated with poorer prognosis and earlier recurrence compared with the conventional breast cancer. Therefore, adequate knowledge of these factors is important in identifying high risk groups and individuals, which will help in screening, early detection and follow-up. This will help to decrease the morbidity and mortality from this life-threatening disease.

    Full Text Available Fungal species are not frequently encountered in an immunocompetent host. Invasive aspergillosis typically occurs in severely immunocompromised patient. Aspergillus infection of breast and chest wall are rarely encountered in an immunocompetent as well as in immunocompromised host. Till date only 13 cases of fungal infection of breast and chest wall have been reported in the literature. This report presents a case of aspergillosis of bilateral breast and chest wall in an immunocompetent male, clinically mimicking breast cancer. Diagnosis was achieved by fine-needle aspiration cytology and subsequently Aspergillus flavus was identified on fungal culture. The patient was successfully treated with voriconazole. Prompt diagnosis by cytology and appropriate treatment is necessary to prevent adverse outcome. Here, we present this rare case of fungal infection of breast and chest wall with relevant review of the literature.

Silimilar results statistically differences were reported on taste, juiciness and tenterness.

  5. Estimation of volumetric breast density for breast cancer risk prediction

    2000-04-01

    Mammographic density (MD) has been shown to be a strong risk predictor for breast cancer. Compared to subjective assessment by a radiologist, computer-aided analysis of digitized mammograms provides a quantitative and more reproducible method for assessing breast density. However, the current methods of estimating breast density based on the area of bright signal in a mammogram do not reflect the true, volumetric quantity of dense tissue in the breast. A computerized method to estimate the amount of radiographically dense tissue in the overall volume of the breast has been developed to provide an automatic, user-independent tool for breast cancer risk assessment. The procedure for volumetric density estimation consists of first correcting the image for inhomogeneity, then performing a volume density calculation. First, optical sensitometry is used to convert all images to the logarithm of relative exposure (LRE), in order to simplify the image correction operations. The field non-uniformity correction, which takes into account heel effect, inverse square law, path obliquity and intrinsic field and grid non- uniformity is obtained by imaging a spherical section PMMA phantom. The processed LRE image of the phantom is then used as a correction offset for actual mammograms. From information about the thickness and placement of the breast, as well as the parameters of a breast-like calibration step wedge placed in the mammogram, MD of the breast is calculated. Post processing and a simple calibration phantom enable user- independent, reliable and repeatable volumetric estimation of density in breast-equivalent phantoms. Initial results obtained on known density phantoms show the estimation to vary less than 5% in MD from the actual value. This can be compared to estimated mammographic density differences of 30% between the true and non-corrected values. Since a more simplistic breast density measurement based on the projected area has been shown to be a strong indicator

    2016-01-01

    Full Text Available Breast cancer is the most common cancer in women and distant site metastasis is the main cause of death in breast cancer patients. There is increasing evidence supporting the role of epithelial-mesenchymal transition (EMT in tumor cell progression, invasion, and metastasis. During the process of EMT, epithelial cancer cells acquire molecular alternations that facilitate the loss of epithelial features and gain of mesenchymal phenotype. Such transformation promotes cancer cell migration and invasion. Moreover, emerging evidence suggests that EMT is associated with the increased enrichment of cancer stem-like cells (CSCs and these CSCs display mesenchymal characteristics that are resistant to chemotherapy and target therapy. However, the clinical relevance of EMT in human cancer is still under debate. This review will provide an overview of current evidence of EMT from studies using clinical human breast cancer tissues and its associated challenges.

    2014-07-13

    The active form of vitamin D, in conjunction with his own receptor, affect a multitude of biological processes in the cell (inter alia it influences the expression of oncogenes and tumor suppressor genes). There is an increasing volume of scientific publications examining the relationships between serum vitamin D levels, vitamin D supplementation and malignant diseases. Some articles suggest inverse relationship between the low serum levels of vitamin D and the breast cancer risk and mortality, whilst other publications do not support this view. Thus the present opinion is conflicted. Vitamin D can exert a beneficial influence on the symptoms and outcomes of a large number of ailments, but its role in affecting cancer is still not completely clear.

    OBJECTIVE Discussion of diagnosis, treatment and prognosis of nonpalpable TO breast cancer.METHODS Between 1978 and 1997, 9,980 female patients with operable breast cancer were treated surgically, of which 276 were determined to have TO breast cancer. Most TO breast cancers could be detected promptly with careful examination of presenting symptoms, such as nipple discharge, local thickening of the breast, nipple erosion, nipple retraction and postmenopausal mastalgia, while 12 cases were detected by routine mammography of the contralateral breast.RESULTS All patients were treated surgically and their tissue subjected to histopathological examination. Most cases (73.0%) were noninvasive or early invasive carcinoma. Axillary lymph nodes metastases were found in 7.69% of 234 mastectomy cases.CONCLUSION The survival rate was significantly increased if the tumor was in an early stage. The 5-, 10-, 15-years survival rates were 98.1%,94.6% and 90.3%, respectively.

    Background: Brain metastases (BM) are frequently diagnosed in patients with HER-2-positive metastatic breast cancer; in addition, an increasing incidence was reported for triple-negative tumours. We aimed to compare brain metastases free survival (BMFS) of breast cancer subtypes in patients treated between 1996 until 2010. Methods: Brain metastases free survival was measured as the interval from diagnosis of extracranial breast cancer metastases until diagnosis of BM. HER-2 status was analysed by immunohistochemistry and reanalysed by fluorescent in situ hybridisation if a score of 2+ was gained. Oestrogen-receptor (ER) and progesterone-receptor (PgR) status was analysed by immunohistochemistry. Brain metastases free survival curves were estimated with the Kaplan–Meier method and compared with the log-rank test. Results: Data of 213 patients (46 luminal/124 HER-2/43 triple-negative subtype) with BM from breast cancer were available for the analysis. Brain metastases free survival differed significantly between breast cancer subtypes. Median BMFS in triple-negative tumours was 14 months (95% CI: 11.34–16.66) compared with 18 months (95% CI: 14.46–21.54) in HER-2-positive tumours (P=0.001) and 34 months (95% CI: 23.71–44.29) in luminal tumours (P=0.001), respectively. In HER-2-positive patients, co-positivity for ER and HER-2 prolonged BMFS (26 vs 15 m; P=0.033); in luminal tumours, co-expression of ER and PgR was not significantly associated with BMFS. Brain metastases free survival in patients with lung metastases was significantly shorter (17 vs 21 months; P=0.014). Conclusion: Brain metastases free survival in triple-negative breast cancer, as well as in HER-2-positive/ER-negative, is significantly shorter compared with HER-2/ER co-positive or luminal tumours, mirroring the aggressiveness of these breast cancer subtypes.

    1976-11-01

    The hallmark of the normal breast thermogram is relative symmetry of vascular configuration and thermal content with preservation of the breast contour. Accepted criteria of abnormality are predicated upon graphic and thermal asymmetry with emphasis placed upon elevated temperature, an increase in the number of discernible vessels, and distorted vascular patterns. The association of a confirmed breast cancer and an avascular thermogram has been labeled a false negative. Avascularity ("cold" breast), particularly in the lower half, with normal vessels in the same location of the opposite breast is suggested as an additional characteristic of abnormality. Illustrative cases are presented.

    A functional DNA repair system has been identified as important in the prevention of tumour development. Previous studies have hypothesized that common polymorphisms in DNA repair genes could play a role in breast cancer risk and also identified the potential for interactions between these polymorphisms and established breast cancer risk factors such as physical activity. Associations with breast cancer risk for 99 single nucleotide polymorphisms (SNPs) from genes in ten DNA repair pathways were examined in a case-control study including both Europeans (644 cases, 809 controls) and East Asians (299 cases, 160 controls). Odds ratios in both additive and dominant genetic models were calculated separately for participants of European and East Asian ancestry using multivariate logistic regression. The impact of multiple comparisons was assessed by correcting for the false discovery rate within each DNA repair pathway. Interactions between several breast cancer risk factors and DNA repair SNPs were also evaluated. One SNP (rs3213282) in the gene XRCC1 was associated with an increased risk of breast cancer in the dominant model of inheritance following adjustment for the false discovery rate (P breast cancer risk or their modification by breast cancer risk factors were observed.

  17. GLUT 5 is not over-expressed in breast cancer cells and patient breast cancer tissues.

    Gayatri Gowrishankar

    Full Text Available F18 2-Fluoro 2-deoxyglucose (FDG has been the gold standard in positron emission tomography (PET oncologic imaging since its introduction into the clinics several years ago. Seeking to complement FDG in the diagnosis of breast cancer using radio labeled fructose based analogs, we investigated the expression of the chief fructose transporter-GLUT 5 in breast cancer cells and human tissues. Our results indicate that GLUT 5 is not over-expressed in breast cancer tissues as assessed by an extensive immunohistochemistry study. RT-PCR studies showed that the GLUT 5 mRNA was present at minimal amounts in breast cancer cell lines. Further knocking down the expression of GLUT 5 in breast cancer cells using RNA interference did not affect the fructose uptake in these cell lines. Taken together these results are consistent with GLUT 5 not being essential for fructose uptake in breast cancer cells and tissues.

    Common variation on 14q24.1, close to RAD51B, has been associated with breast cancer: rs999737 and rs2588809 with the risk of female breast cancer and rs1314913 with the risk of male breast cancer. The aim of this study was to investigate the role of RAD51B variants in breast cancer predisposition, particularly in the context of familial breast cancer in Finland. We sequenced the coding region of RAD51B in 168 Finnish breast cancer patients from the Helsinki region for identification of possible recurrent founder mutations. In addition, we studied the known rs999737, rs2588809, and rs1314913 SNPs and RAD51B haplotypes in 44,791 breast cancer cases and 43,583 controls from 40 studies participating in the Breast Cancer Association Consortium (BCAC) that were genotyped on a custom chip (iCOGS). We identified one putatively pathogenic missense mutation c.541C>T among the Finnish cancer patients and subsequently genotyped the mutation in additional breast cancer cases (n = 5259) and population controls (n = 3586) from Finland and Belarus. No significant association with breast cancer risk was seen in the meta-analysis of the Finnish datasets or in the large BCAC dataset. The association with previously identified risk variants rs999737, rs2588809, and rs1314913 was replicated among all breast cancer cases and also among familial cases in the BCAC dataset. The most significant association was observed for the haplotype carrying the risk-alleles of all the three SNPs both among all cases (odds ratio (OR): 1.15, 95% confidence interval (CI): 1.11–1.19, P = 8.88 x 10−16) and among familial cases (OR: 1.24, 95% CI: 1.16–1.32, P = 6.19 x 10−11), compared to the haplotype with the respective protective alleles. Our results suggest that loss-of-function mutations in RAD51B are rare, but common variation at the RAD51B region is significantly associated with familial breast cancer risk. PMID:27149063

    2014-03-01

    The increased use of mammography and introduction of breast screening programmes have resulted in a rise in clinically-occult breast cancer, with one-third of all breast carcinomata diagnosed being non-palpable. These types of cancer have a unique natural history and biology compared to symptomatic breast cancer and this needs to be taken into account when considering surgery and adjuvant treatment. The majority of studies demonstrating efficacy of adjuvant treatments are largely based on patients with symptomatic breast cancer. The current evidence for the role of surgery and adjuvant therapy for screen-detected breast cancer was reviewed in light of their improved prognosis, compared to symptomatic breast cancer.

    Objective: To study the biological characteristics, the therapeutic procedure and the prognosis of male breast cancer.Methods: 34 patients with male breast cancer were retrospectively analyzed, who were diagnosed and treated in the First Hospital of Jilin University between 1980 and March 2005. Results: Clinical TNM stage of the patients were stage Ⅰ, 6patients, stage Ⅱ, 24 patients and stage Ⅲ, 4 patients. Positive lymph nodes were found in 35.3% of the patients. All these patients received modified radical mastectomy. The 5-year survival rate was 65.3%. Postoperation recurrence rate was 11.8%.Conclusions: Patients with male breast cancer should receive surgical treatment, assisted with adjuvant treatment, such as radiotherapy, chemotherapy, endocrine therapy and so on. TNM stage and expression of hormone receptor may be the main factors affecting the prognosis.
