    Between 1986 and 1992, 10 patients (12 lesions) of advanced breast cancer were treated with multidisciplinary treatment including brachytherapy. The lesions treated included 5 primary breast tumors, 3 metastatic lesions in the contra lateral breast, 2 recurrences after external beam irradiation, 1 metastasis to the axillary lymph node and 1 metastasis to the upper arm skin. The interstitial irradiation techniques used were [sup 192]Ir low dose-rate irradiation for 5 lesions and high dose-rate for 7 lesions (including 3 with mould irradiation). External hyperthermia as performed for 6 lesions and interstitial hyperthermia were performed for 4 lesions. The local response was CR for 3 lesions, PRa for 8 lesions, PRb for 1 lesion with the local response rate being 100%. Excellent local control could be achieved by combination external and interstitial irradiation, indicating that radiotherapy is definitely useful for the treatment of advanced breast cancer.

    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

  1. Breast cancer: Postoperative irradiation and management of locally advanced disease

    International Nuclear Information System (INIS)

    Purpose/Objective: This course will review current indications for postoperative irradiation, present a videotape demonstration of a simulation technique for comprehensive chest wall/nodal irradiation, and discuss multimodality approaches to the difficult problem of locally advanced breast cancer. As part of an expanding role for the radiation oncologist in the treatment of all stages of breast cancer, recent data has inspired a reevaluation of chest wall and nodal irradiation following mastectomy. A decade ago, adjuvant irradiation was considered by many oncologists to be of no survival advantage or perhaps even harmful. Studies leading to this conclusion will be reviewed with special attention to the inadequacies and flawed constructs which biased these studies against adjuvant chest wall/nodal irradiation. The Fischer hypothesis or 'new paradigm' will be challenged. Can improvement in local control result in improved survival? If the goal of treatment is simply to reduce local-regional recurrence, a three-field technique covering the chest wall and supraclavicular nodes may suffice. But if the goal is an improvement in survival based on the treatment of all locoregional sites which may not be sterilized by chemotherapy and mastectomy, a more complex set of fields is required. Based on this premise, we designed a 5-field technique of comprehensive chest wall and nodal irradiation. Simulation of these fields will be demonstrated on videotape. Treatment strategies for both non-inflammatory and inflammatory non-metastatic breast cancer will be presented. Current recommendations include various combinations of chemohormonotherapy, radiation therapy, and mastectomy, but controversies abound regarding the proper sequencing of these modalities, whether breast conservation therapy can be offered to patients who have a dramatic response to systemic therapy, and whether or not any one of these treatment modalities can be dropped under specific clinical scenarios

Neoadjuvant chemotherapy (NACT has made a tremendous impact on the management of LABC. NACT was initiated to institute systemic therapy upfront at the earliest in this group of patients with a high risk of micrometastasis burden. While NACT did not yield a survival advantage, it has however made breast conservation possible in selected group of cases. Large number of studies and many randomised trials have been done in women with LABC in order to improve the therapeutic decisions and also the local control and survival. With this background we have reviewed various treatment options in patients with LABC which should possibly help in guiding the clinicians for optimal management of LABC.

    Breast cancer is one kind of multi-gene related malignancy.Overexpression of some oncogenes such as HER-2(c-erbB-2,Neu),bcl-2/bcl-xL,protein kinase A(PKA),and transferrin receptor gene(TfR gene),etc significantly affect the prognosis of breast cancer.It was shown that specific suppression of the overexpressed genes above resulted in the improvement of the therapy of breast cancer.Antisense interference.one of useful tools for inhibiting the overexpression of specific oncogenes,was involved in the therapy of breast cancer in recent years. Data indicated that antisense oligonucleotides(ON)could inhibit specially the expression of the target genes on mRNA or protein levels in most of cases;some ON candidates showed encouraging therapeutic effects in vitro and in vivo on breast cancer cell lines or xenografts.Furthermore,the combination use of the antisense ON and normal chemotherapeutic agents indicated synergistic antitumor effects,which was probably the best utilization of antisense ON in the treatment of breast cancer.

From 1997 to 2011, 170 patients were treated with NAC and mastectomy at our center; 98 cases (57.6%) underwent PMRT and 72 cases (42.4%) did not receive radiation. At a median follow-up period of 7.7 years (range 2-16) for the whole cohort, median time to locoregional recurrence (LRR) was 3.3 years (range 0.7-12.4). The 5-year and 10-year actuarial LRR rate were 14.5% and 15.9%, respectively. At the multivariate analysis the factors that significantly correlated with survival outcome were ≥ 4 positive nodes (HR 5.0, 1.51-16.52; P = 0.035), extracapsular extension (HR 2.18, 1.37-3.46; P = 0.009), and estrogen receptor positive disease (HR 0.57, 0.36-0.90; P = 0.003). Concerning LRR according to use of radiation, PMRT reduced LRR for patient with clinical T3 staged disease (P = 0.015). Our experience confirmed the impact of pathological nodal involvement on survival outcome. PMRT was found to improve local control in patients presenting with clinical T3 tumors, regardless of the response to chemotherapy. PMID:25045694

    Full Text Available Allan LiptonMilton S. Hershey Medical Center, Pennsylvania State University, Hershey, PA, USAAbstract: Bisphosphonates inhibit osteoclast-mediated bone resorption, thereby inhibiting the release of growth factors necessary to promote cancer cell growth, differentiation, and tumor formation in bone. These agents have demonstrated efficacy for delaying the onset and reducing the incidence of skeletal-related events in the advanced breast cancer setting, and have been shown to prevent cancer therapy-induced bone loss in the early breast cancer setting. Emerging clinical data indicate that the role of bisphosphonates in advanced and early breast cancer is evolving. Retrospective analyses and recent clinical trial data show that zoledronic acid may improve outcomes in some patients with breast cancer. Data from ABCSG-12 and ZO-FAST suggest that zoledronic acid may improve disease-free survival in the adjuvant breast cancer setting in postmenopausal women or women with endocrine therapy-induced menopause, and recent data from a predefined subset of the AZURE trial added to the anticancer story. However, the overall negative AZURE trial also raises questions about the role of bisphosphonates as an anticancer agent in patients with breast cancer. Overall, these data suggest that the addition of zoledronic acid to established anticancer regimens may have potential anticancer benefits in specific patient populations, although more studies are required to define its role.Keywords: anticancer, adjuvant therapy, bone metastasis, skeletal, zoledronic acid

    International Nuclear Information System (INIS)

    Full text of publication follows. Introduction: breast cancer is a solid cancer which can often be complicated by metastatic bone pain, reducing performance status and decreasing the quality of life. Quadramet is a radiopharmaceutical consisting of stable complexes of radioactive Samarium (Sm-153) and tetra-phosphonate chelators (EDTMP), having a high affinity to the skeleton more intense in osteoblastic lesions. It is indicated as a palliative measure for the relief of pain from metastatic lesions that enhance on bone scans. Our aim was to assess the effect of Sm-153 in breast cancer. Methods: the study included 10 patients with breast cancer (mean age 43, 5 years) with multiple bone painful metastases detected by scintigraphy. Each patient received 37 MBq/kg of Sm-153. For assessment of therapy effectiveness; pain relief, a reduction in analgesic requirements and motor activity (Karnofsky scale) were evaluated with a receding of 36 months. Results: palliative therapy using Sm-153 is effective (in 2/3 of cases 'good' and 'moderate' response rate) and we have observed that the analgesic requirements decreased to 40% of dose on average. The motor activity of the points evaluated according to Karnofsky scale increased from 50 to 70. Conclusion: in breast cancer, bone metastasis is a major complication which is most often associated with pain. Bone pain palliation therapy with Sm-153 is a cost-effective systemic therapy to relieve pain from skeletal metastases with a consequent decrease in morbidity and an improvement in quality of life

    Full Text Available Neoadjuvant chemotherapy (NAC is widely used in locally advanced breast cancer (BC treatment. The role of postmastectomy radiotherapy (PMRT after NAC is strongly debated. The aim of our analysis was to identify major prognostic factors in a single-center series, with emphasis on PMRT. From 1997 to 2011, 170 patients were treated with NAC and mastectomy at our center; 98 cases (57.6% underwent PMRT and 72 cases (42.4% did not receive radiation. At a median follow-up period of 7.7 years (range 2–16 for the whole cohort, median time to locoregional recurrence (LRR was 3.3 years (range 0.7–12.4. The 5-year and 10-year actuarial LRR rate were 14.5% and 15.9%, respectively. At the multivariate analysis the factors that significantly correlated with survival outcome were ≥4 positive nodes (HR 5.0, 1.51–16.52; P=0.035, extracapsular extension (HR 2.18, 1.37–3.46; P=0.009, and estrogen receptor positive disease (HR 0.57, 0.36–0.90; P=0.003. Concerning LRR according to use of radiation, PMRT reduced LRR for patient with clinical T3 staged disease (P=0.015. Our experience confirmed the impact of pathological nodal involvement on survival outcome. PMRT was found to improve local control in patients presenting with clinical T3 tumors, regardless of the response to chemotherapy.

    Adjuvant systemic therapy has contributed to a significant improvement of disease-free and overall survival in addition to surgery and irradiation to the local disease. The adjuvant therapy to a patient is determined integrating the information on estimated risk of recurrence, benefit and harm of the therapy and the patient's value. In this review, the state of the art of adjuvant therapy is discussed from several aspects, such as interpretation and evaluation of risk, the best available evidences on adjuvant systemic therapy, the future direction of primary therapy for breast cancer, and patient-oriented decision making.

    Full Text Available Abstract Background Combining gene expression microarrays and high resolution magic angle spinning magnetic resonance spectroscopy (HR MAS MRS of the same tissue samples enables comparison of the transcriptional and metabolic profiles of breast cancer. The aim of this study was to explore the potential of combining these two different types of information. Methods Breast cancer tissue from 46 patients was analyzed by HR MAS MRS followed by gene expression microarrays. Two strategies were used to combine the gene expression and metabolic data; first using multivariate analyses to identify different groups based on gene expression and metabolic data; second correlating levels of specific metabolites to transcripts to suggest new hypotheses of connections between metabolite levels and the underlying biological processes. A parallel study was designed to address experimental issues of combining microarrays and HR MAS MRS. Results In the first strategy, using the microarray data and previously reported molecular classification methods, the majority of samples were classified as luminal A. Three subgroups of luminal A tumors were identified based on hierarchical clustering of the HR MAS MR spectra. The samples in one of the subgroups, designated A2, showed significantly lower glucose and higher alanine levels than the other luminal A samples, suggesting a higher glycolytic activity in these tumors. This group was also enriched for genes annotated with Gene Ontology (GO terms related to cell cycle and DNA repair. In the second strategy, the correlations between concentrations of myo-inositol, glycine, taurine, glycerophosphocholine, phosphocholine, choline and creatine and all transcripts in the filtered microarray data were investigated. GO-terms related to the extracellular matrix were enriched among the genes that correlated the most to myo-inositol and taurine, while cell cycle related GO-terms were enriched for the genes that correlated the most

Paclitaxel and docetaxel have poor solubility and require a complex solvent system for their commercial formulation, Cremophor EL® (CrEL and Tween 80® respectively. Both these biological surfactants have recently been implicated as contributing not only to the hypersensitivity reactions, but also to the degree of peripheral neurotoxicity and myelosuppression, and may antagonize the cytotoxicity. Nab-paclitaxel, or nanoparticle albumin-bound paclitaxel (ABI-007; Abraxane®, is a novel formulation of paclitaxel that does not employ the CrEL solvent system. Nab-paclitaxel demonstrates greater efficacy and a favorable safety profile compared with standard paclitaxel in patients with advanced disease (breast cancer, non-small cell lung cancer, melanoma, ovarian cancer. Clinical studies in breast cancer have shown that nab-paclitaxel is significantly more effective than standard paclitaxel in terms of overall objective response rate (ORR and time to progression. Nab-paclitaxel in combination with gemcitabine, capecitabine or bevacizumab has been shown to be very active in patients with advanced breast cancer. An economic analysis showed that nab-paclitaxel would be an economically reasonable alternative to docetaxel or standard paclitaxel in metastatic breast cancer. Favorable tumor ORR and manageable toxicities have been reported for nab-paclitaxel as monotherapy or in combination treatment in advanced breast cancer.Keywords: breast cancer, nab-paclitaxel, 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.

  15. Early breast cancer

    International Nuclear Information System (INIS)

    Breast cancer remains a common disease throughout the world. Here we review new knowledge about early breast cancer obtained during the past 5 years. The prognosis of early breast cancer is generally favorable. Especially, ductal carcinoma in situ has been regarded as a non-life-threatening disease. Therefore, early diagnosis and early onset of the treatment has been important. Early age at menarche, late age at first birth, and late age at menopause are related to breast cancer risk. Examination by mammography and ultrasonography is still the most effective means of detection for premenopausal and postmenopausal women, respectively. Additionally, there have been important advances in MRI, sentinel lymph node biopsy, breast-conserving surgery, partial breast irradiation, neoadjuvant systemic therapy, and adjuvant systemic therapy. Another approach to keeping the disease under control is the elucidation of breast cancer's molecular biological features. Assessment of potential molecular targets can lead to early diagnosis and molecular targeted treatment. (author)

    More than 20-year follow-up of A-bomb survivors in Hiroshima and Nagasaki has a crucial role in determining the relationship of radiation to the occurrence of breast cancer. In 1967, Wanebo et al have first reported 27 cases of breast cancer during the period 1950-1966 among the Adult Health Study population of A-bomb survivors. Since then, follow-up surveys for breast cancer have been made using the Life Span Study (LSS) cohort, and the incidence of breast cancer has increased year by year; that is breast cancer was identified in 231 cases by the first LSS series (1950-1969), 360 cases by the second LSS series (1950-1974), 564 cases by the third LSS series (1950-1980), and 816 cases in the fourth LSS series (1950-1085). The third LSS series have revealed a high risk for radiation-induced breast cancer in women aged 10 or less at the time of exposure (ATE). Both relative and absolute risks are found to be decreased with increasing ages ATE. Based on the above-mentioned findings and other studies on persons exposed medical radiation, radiation-induced breast cancer is characterized by the following: (1) the incidence of breast cancer is linearly increased with increasing radiation doses; (2) both relative and absolute risks for breast cancer are high in younger persons ATE; (3) age distribution of breast cancer in proximally exposed A-bomb survivors is the same as that in both distally A-bomb survivors and non-exposed persons, and there is no difference in histology between the former and latter groups. Thus, immature mammary gland cells before the age of puberty are found to be most radiosensitive. (N.K.)

    Full Text Available William GradisharRobert H Lurie Comprehensive Cancer Center, Northwestern University Feinberg School of Medicine, Chicago, IL, USAAbstract: Despite the activity of standard chemotherapies in advanced breast cancer, disease progression remains inevitable. Most patients exposed to anthracyclines and taxanes develop resistance and a significant subset shows primary resistance. The increasing use of these agents as adjuvant therapy may result in more anthracycline- and taxane-resistant patients in the metastatic setting; few treatment options are available for patients with metastatic breast cancer (MBC resistant to multiple chemotherapies. The heterogeneity of breast cancer represents another therapeutic challenge. Breast cancers may be classified as luminal, human epidermal growth factor 2 (HER2-positive, or estrogen receptor-, progesterone receptor-, and human epidermal growth factor 2-negative (ER/PR/HER2-negative, triple negative. HER2-positive and ER/PR/HER2-negative tumors are associated with poor prognosis owing to aggressive disease and poor long-term response to therapy. The epothilone B analog ixabepilone has low susceptibility to multiple mechanisms of resistance and has demonstrated activity in patients with MBC resistant to anthracyclines, taxanes, and/or capecitabine. Ixabepilone is the first epothilone to be approved, as monotherapy or in combination with capecitabine, for treatment of resistant/refractory MBC or locally advanced breast cancer. Treatment with ixabepilone is an option for patients with ER/PR/HER2-negative or HER2-positive disease and/or primary resistance to taxanes.Keywords: breast cancer, drug resistance, epothilone, HER2-positive, ixabepilone, ER/PR/HER2-negative (triple negative

    2014-09-01

    Full Text Available For many years, tamoxifen has been the _gold standard_ amongst anti-oestrogen therapies for breast cancer. However, the selective aro- matase inhibitors (AIs, anastrozole, letrozole and exemestane, have demonstrated advantages over tamoxifen as first-line treatments for advanced disease. Anastrozole is also more effective as an adjuvant treatment in early, operable breast cancer and is being increasingly used in the adjuvant setting. Generally, the selective oestrogen receptor modulators (SERMs, such as toremifene, droloxifene, idoxifene, ralox- ifene, and arzoxifene, show minimal activity in tamoxifen-resistant disease and show no superiority over tamoxifen as first-line treatments. In addition to these agents, other treatment options for advanced disease include high-dose oestrogens and progestins. Response rates for high- dose oestrogens and tamoxifen are similar, but the use of oestrogens is limited by their toxicity profile. Consequently, there is a need for new endocrine treatment options for breast cancer, particularly for use in disease that is resistant to tamoxifen or AIs. Fulvestrant (_Faslodex_ is a new type of steroidal oestrogen receptor (ER antagonist that downregulates cellular levels of the ER and progesterone receptor and has no agonist activity. This paper reviews the key efficacy and tolerability data for fulvestrant in postmenopausal women in the context of other endocrine therapies and explores the potential role of fulvestrant within the sequencing of endocrine therapies for advanced breast cancer.

    Full Text Available A need exists for a breast cancer risk identification paradigm that utilizes relevant demographic, clinical, and other readily obtainable patient-specific data in order to provide individualized cancer risk assessment, direct screening efforts, and detect breast cancer at an early disease stage in historically underserved populations, such as younger women (under age 40 and minority populations, who represent a disproportionate number of military beneficiaries. Recognizing this unique need for military beneficiaries, a consensus panel was convened by the USA TATRC to review available evidence for individualized breast cancer risk assessment and screening in young (< 40, ethnically diverse women with an overall goal of improving care for military beneficiaries. In the process of review and discussion, it was determined to publish our findings as the panel believes that our recommendations have the potential to reduce health disparities in risk assessment, health promotion, disease prevention, and early cancer detection within and in other underserved populations outside of the military. This paper aims to provide clinicians with an overview of the clinical factors, evidence and recommendations that are being used to advance risk assessment and screening for breast cancer in the military.

    Purpose: Tumor grading is an important part of breast cancer diagnosis and currently requires biopsy as its standard. Here, the authors investigate quantitative ultrasound parameters in locally advanced breast cancers that can potentially separate tumors from normal breast tissue and differentiate tumor grades. Methods: Ultrasound images and radiofrequency data from 42 locally advanced breast cancer patients were acquired and analyzed. Parameters related to the linear regression of the power spectrum—midband fit, slope, and 0-MHz-intercept—were determined from breast tumors and normal breast tissues. Mean scatterer spacing was estimated from the spectral autocorrelation, and the effective scatterer diameter and effective acoustic concentration were estimated from the Gaussian form factor. Parametric maps of each quantitative ultrasound parameter were constructed from the gated radiofrequency segments in tumor and normal tissue regions of interest. In addition to the mean values of the parametric maps, higher order statistical features, computed from gray-level co-occurrence matrices were also determined and used for characterization. Finally, linear and quadratic discriminant analyses were performed using combinations of quantitative ultrasound parameters to classify breast tissues. Results: Quantitative ultrasound parameters were found to be statistically different between tumor and normal tissue (p < 0.05). The combination of effective acoustic concentration and mean scatterer spacing could separate tumor from normal tissue with 82% accuracy, while the addition of effective scatterer diameter to the combination did not provide significant improvement (83% accuracy). Furthermore, the two advanced parameters, including effective scatterer diameter and mean scatterer spacing, were found to be statistically differentiating among grade I, II, and III tumors (p = 0.014 for scatterer spacing, p = 0.035 for effective scatterer diameter).

  10. Quantitative ultrasound characterization of locally advanced breast cancer by estimation of its scatterer properties

    International Nuclear Information System (INIS)

    Purpose: Tumor grading is an important part of breast cancer diagnosis and currently requires biopsy as its standard. Here, the authors investigate quantitative ultrasound parameters in locally advanced breast cancers that can potentially separate tumors from normal breast tissue and differentiate tumor grades. Methods: Ultrasound images and radiofrequency data from 42 locally advanced breast cancer patients were acquired and analyzed. Parameters related to the linear regression of the power spectrum—midband fit, slope, and 0-MHz-intercept—were determined from breast tumors and normal breast tissues. Mean scatterer spacing was estimated from the spectral autocorrelation, and the effective scatterer diameter and effective acoustic concentration were estimated from the Gaussian form factor. Parametric maps of each quantitative ultrasound parameter were constructed from the gated radiofrequency segments in tumor and normal tissue regions of interest. In addition to the mean values of the parametric maps, higher order statistical features, computed from gray-level co-occurrence matrices were also determined and used for characterization. Finally, linear and quadratic discriminant analyses were performed using combinations of quantitative ultrasound parameters to classify breast tissues. Results: Quantitative ultrasound parameters were found to be statistically different between tumor and normal tissue (p < 0.05). The combination of effective acoustic concentration and mean scatterer spacing could separate tumor from normal tissue with 82% accuracy, while the addition of effective scatterer diameter to the combination did not provide significant improvement (83% accuracy). Furthermore, the two advanced parameters, including effective scatterer diameter and mean scatterer spacing, were found to be statistically differentiating among grade I, II, and III tumors (p = 0.014 for scatterer spacing, p = 0.035 for effective scatterer diameter).

    Full Text Available Abstract Background Neoadjuvant chemotherapy is the standard care for locally advanced breast cancer. Our study aimed at evaluating the feasibility of breast conversation surgery (BCS after neoadjuvant chemotherapy. Patients and methods Forty five patients had stage IIB (except those with T2N1 disease and stage IIIA were selected to 3 cycles taxane-based neoadjuvant chemotherapy. Patient who had tumours ≤5 cm underwent a tentative BCS while patients who had tumour size >5 cm underwent radical surgery. Negative margin is essential for BCS. Adjuvant chemotherapy and 3-D radiotherapy ± hormonal treatment were given to all patients. Results Thirty four patients had BCS. Response to chemotherapy was the only statistically significant factor which influences the BCS. Incidence of local recurrence was 5.9% for patients who had BCS at a median follow up 24 months. Conclusion Breast conservation is feasible in selected cases of locally advanced, non metastatic cancer breast. We recommend that patients who have tumour size ≤4 cm after chemotherapy are the best candidates for BCS.

  14. Anti-EGFR Therapy: Mechanism and Advances in Clinical Efficacy in Breast Cancer

    Directory of Open Access Journals (Sweden)

    John F. Flynn

    2009-01-01

    Full Text Available This review will focus on recent advances in the application of antiepidermal growth factor receptor (anti-EGFR for the treatment of breast cancer. The choice of EGFR, a member of the ErbB tyrosine kinase receptor family, stems from evidence pinpointing its role in various anti-EGFR therapies. Therefore, an increase in our understanding of EGFR mechanism and signaling might reveal novel targets amenable to intervention in the clinic. This knowledge base might also improve existing medical treatment options and identify research gaps in the design of new therapeutic agents. While the approved use of drugs like the dual kinase inhibitor Lapatinib represents significant advances in the clinical management of breast cancer, confirmatory studies must be considered to foster the use of anti-EGFR therapies including safety, pharmacokinetics, and clinical efficacy.

    International Nuclear Information System (INIS)

    To assess the effect of group psychotherapy in the management of the side effects of chemotherapy treatment in advanced breast and lung cancer. One hundred patients treated with chemotherapy for advanced stage (IIIB and IV) breast and lung cancer were selected with ECOG performance status of 0 or 1. All patients received anti-emetic medications half an hour before chemotherapy. All those patients in this category who completed fist line chemotherapy with 6 cycles were included. Fifty were subjected to group discussions with other patients, family members and medical staff. This was labeled group A. The other 50 were not included in group discussion and were labeled group B. Both the group received similar standard chemotherapy and pre-medication for vomiting as per their disease and chemotherapy schedule. Breast and lung cancer patients were 29 and 21 in each arm respectively. At the end of the discharge, grade 2 and above of vomiting, according to common terminology criteria for adverse events (CTCAE) was counted for all patients in both the arms A and B, over full length of treatment for 6 cycles, and then were compared statistically. Mean with standard deviation for adverse event (vomiting) in group A and B was 6.2 + 2.6 and 13.4 + 3.8 respectively per cycle of treatment. It was observed that group psychotherapy had statistically significant effect (p-value <0.05) on the management of vomiting. Group psychotherapy can be used to reduce the incidence of vomiting in advanced breast and lung cancer patients treated with chemotherapy. (author)

    For the patients with breast cancer that are locally advanced or metastatic, treatment to control not only local disease but also distant metastasis is desirable. Hyperthermo-radio-chemotherapy (HRC) combined with surgery was performed for 16 patients with stage III or stage IV breast cancer and the clinical outcomes of this multimodal treatment were analyzed. The size of the primary tumor was significantly reduced after preoperative HRC with the CR rate of 18.8% (3/16) and PR rate of 81.3% (13/16). Three- and 5-year overall survival rates for the stage III patients were 100% and 87.5%, respectively; their 3- and 5- year disease free rates were 78.8% and 52.5%, respectively. One- and 3-year survival rates for the stage IV patients were 80.0% and 20.0%, respectively. No loco-regional recurrence was observed. HRC combined with surgery for advanced breast cancer patients was effective for down-staging of the primary tumor and maintaining local control. (author)

    Full Text Available Breast cancer currently is a major health problem among women worldwide accounting for around 13.7% cancer deaths, nearly 1/3rd of it being due to Locally advanced breast cancer (LABC. Despite progress achieved in diagnosis & therapy of Breast cancer, LABC remains a major clinical challenge and in efforts to increase pCR, CCR & DFS in LABC, Neoadjuvant or primary chemotherapy followed by locoregional therapy and adjuvant systemic CT is well accepted treatment strategy since last 3 decades. Further to address the issue of drug resistance in NACT sequential anthracycline-taxane NACT has been evaluated by many researchers and has resulted in better outcome in terms of overall survival and pCR. In this study we have evaluated 4 cycles of sequential anthracycline-taxane, 2 cycles of Cyclophosphamide, Epirubicin, Fluracil +2 cycles of Docetaxel, Epirubicin (CEF- DE NACT in a series of 10 cases of ER/PR +ve, Her -2 neu negative patients of LABC. 9/10 cases were rendered operable after primary chemotherapy and were subjected to further 4 cycles of adjuvant chemotherapy (1 cycle CEF, 1 cycle DE, 2cycles single agent Docetaxel, followed by locoregional RT. This tailored sequential NACT protocol in our subgroup of patient was well tolerated, well accepted and resulted in substantial increase in operability with CCR & DFS in 6/10 cases on 3 years follow up and pCR in one patient. Sequential NACT needs further validation by more RCT with extensive follow up

  10. Experience in treatment of patients with locally advanced or recurrent breast cancer. Intraarterial infusion chemotherapy combined with radiotherapy

    International Nuclear Information System (INIS)

    For the purpose of local control and breast conservation, intraarterial infusion chemotherapy combined with radiotherapy has been indicated in patients with locally advanced breast cancer both in primary and recurrent cases. The present series, evaluated during the past 4 years, consisted of 15 patients 35-83 years of age, with invasive ductal carcinoma, including 10 with primary breast cancer (stage IIIb: 1, IV: 9) and 5 with postoperative recurrence (stage IIIb: 2, IV: 3). Intraarterial chemotherapy is started, basically infusing ADM 50 mg, MMC 10 mg and CDDP 50 mg into the internal thoracic and/or subclavian artery 1-3 times, followed by reduction surgery (quadrantectomy: 4, wide resection: 2) and radiotherapy to the breast, supraclavicular, parasternal and cervical regions according to tumor extent. Local response after arterial infusion was CR: 2, PR: 10, NC: 3 (response rate: 73% ). The response rate of distant metastases after arterial infusion was 73%. Of 10 patients with primary breast cancer, recurrence was noted in 1. Breast conservation was successful in 8 of 10 patients. One of them, in stage IIIb, has survived for 4.5 years with no evidence of disease and with breast conservation. Five patients with postoperative recurrence showed CR with no recurrence after intraarterial chemotherapy and radiotherapy. Acute skin reaction occurred in 6 patients, and was especially frequent in patients with postoperative recurrence (4 of 5). According to these results, combined therapy affords breast conservation even in patients with locally advanced breast cancer, and improves patient's QOL in stage IV. (author)

  12. Radioresponsiveness of locally advanced breast cancer. Analysis of factors influencing the response to radiation therapy

    International Nuclear Information System (INIS)

    The radioresponsiveness of locally advanced breast cancer was studied in 239 patients treated with primary RT from 1977 to 1985. The response to RT was assessed on clinical and histological bases. For patients with no residual disease or heavily damaged residual disease in the breast and negative axillary lymph nodes after RT, the 5-year probability of local tumour control (LTC) was 90%. Response to RT was mainly affected by the T and N stages. Primary tumour size or RT dose had only a moderate influence on tumour response in this stage of the disease. The 5-year LTC was 37% for N3 and 43% for T4d conditions. Heavy tumour tissue damage was associated with microcapillary lesions, while the microvasculature around the florid tumour growth was in better condition. Microcapillaries have to be regarded as an important target in RT. The oxygen supply may worsen during fractionated RT as a result of vascular damage. Chronically hypoxic cells may be killed earlier than euoxic ones. Findings indicate that the radioresponsiveness of locally advanced breast cancer is more likely to be attributable to the biological nature of the disease than to chronically hypoxic cells present during RT.

    Breast cancer is the malignant neoplasia with the highest incidence in women worldwide. Chronic oxidative stress and inflammation have been indicated as major mediators during carcinogenesis and cancer progression. Human studies have not considered the complexity of tumor biology during the stages of cancer advance, limiting their clinical application. The purpose of this study was to characterize systemic oxidative stress and immune response parameters in early (ED; TNM I and II) and advanced disease (AD; TNM III and IV) of patients diagnosed with infiltrative ductal carcinoma breast cancer. Oxidative stress parameters were evaluated by plasmatic lipoperoxidation, carbonyl content, thiobarbituric reactive substances (TBARS), nitric oxide levels (NO), total radical antioxidant parameter (TRAP), superoxide dismutase, and catalase activities and GSH levels. Immune evaluation was determined by TNF-α, IL-1β, IL-12, and IL-10 levels and leukocytes oxidative burst evaluation by chemiluminescence. Tissue damage analysis included heart (total CK and CKMB), liver (AST, ALT, GGT), and renal (creatinine, urea, and uric acid) plasmatic markers. C-reactive protein (CRP) and iron metabolism were also evaluated. Analysis of the results verified different oxidative stress statuses occur at distinct cancer stages. ED was characterized by reduction in catalase, 8-isoprostanes, and GSH levels, with enhanced lipid peroxidation and TBARS levels. AD exhibited more pronounced oxidative status, with reduction in catalase activity and TRAP, intense lipid peroxidation and high levels of NO, TBARs, and carbonyl content. ED patients presented a Th2 immune pattern, while AD exhibited Th1 status. CRP levels and ferritin were increased in both stages of disease. Leukocytes burst impairment was observed in both the groups. Plasma iron levels were significantly elevated in AD. The data obtained indicated that oxidative stress enhancement and immune response impairment may be necessary to ensure

  18. Retrospective Analysis of Locally Advanced Noninflammatory Breast Cancer From Chennai, South India, 1990-1999

    International Nuclear Information System (INIS)

    Purpose: This was a retrospective observational study to elicit the outcome of the therapeutic strategy of concurrent neoadjuvant chemoradiotherapy protocol for locally advanced breast cancer. Methods and Materials: A large series of 1,117 consecutive cases of locally advanced breast cancer treated at the Cancer Institute (WIA), in Chennai, South India, between 1990 and 1999 and followed through 2004 formed the basis for this study. Disease-free survival was the main outcome, and nodal and tumor downstaging were the intermediate outcome measures studied. Results: Primary tumor downstaging was observed in 45% and nodal downstaging in 57.5%. The disease-free survival rate of nodal downstaged patients at 5, 10, and 15 years was 75%, 65%, and 58%, respectively. The corresponding rates for pre- and postoperative node-negative patients were 70%, 60%, and 59%. The best survival was seen among those who were tumor and node negative postoperatively. Nodal downstaging halved the risk of disease recurrence and death compared with node positivity, irrespective of tumor sterility. Conclusions: A randomized trial using cyclophosphamide, methotrexate, and 5-fluorouracil vs. an anthracycline-based regimen in the setting of concurrent chemoradiotherapy appears indicated. Additional preoperative chemotherapy to maximize nodal and tumor downstaging should be investigated. A change in postoperative chemotherapy according to nodal status could also be explored

    2016-10-01

    Clinical trials in breast cancer have contributed immensely to the advancements of modern multimodal breast cancer treatment. Due to improved screening methods and more effective biologic-based tailored systemic therapies, the extent of surgery necessary for local and systemic control of disease is decreasing. Sequential trials for ductal carcinoma in situ (DCIS) have changed the management of this disease and are culminating in randomized active surveillance studies in an effort potentially to prevent overtreatment of low- and intermediate-grade disease. For patients with initial node-positive disease, clipping and marking of the biopsy-proven nodal metastases before the start of neoadjuvant chemotherapy can allow for selective node dissection based on the axillary response. With the current advances in primary systemic therapy, feasibility trials are beginning to investigate the potential of nonoperative therapy for invasive cancers with percutaneously documented pathologic complete response. This article presents a review and update on landmark clinical trials related to DCIS, the extent of axillary surgery in node-positive disease, and the integration of systemic therapy with local therapy.

    A proportion of patients with hormone receptor-positive locally advanced or metastatic breast cancer will not have received prior endocrine therapy. However, there are limited clinical data specifically in these patients. We conducted a review of randomized phase II and III clinical studies of anastrozole, letrozole, exemestane, palbociclib, and fulvestrant to determine the evidence base supporting use of specific endocrine therapies in this patient population. From our findings, there is a paucity of clinical studies in patients with endocrine therapy-naïve disease; however, it appears that first-line treatment effects are consistent between patients who have and have not received prior endocrine treatment.

    To assess whether DCE-MRI pharmacokinetic (PK) parameters obtained before and during chemotherapy can predict pathological complete response (pCR) differently for different breast cancer groups. Eighty-four patients who received neoadjuvant chemotherapy for locally advanced breast cancer were retrospectively included. All patients underwent two DCE-MRI examinations, one before (EX1) and one during treatment (EX2). Tumours were classified into different breast cancer groups, namely triple negative (TNBC), HER2+ and ER+/HER2-, and compared with the whole population (WP). PK parameters Ktrans and Ve were extracted using a two-compartment Tofts model. At EX1, Ktrans predicted pCR for WP and TNBC. At EX2, maximum diameter (Dmax) predicted pCR for WP and ER+/HER2-. Both PK parameters predicted pCR in WP and TNBC and only Ktrans for the HER2+. pCR was predicted from relative difference (EX1 - EX2)/EX1 of Dmax and both PK parameters in the WP group and only for Ve in the TNBC group. No PK parameter could predict response for ER+/HER-. ROC comparison between WP and breast cancer groups showed higher but not statistically significant values for TNBC for the prediction of pCR Quantitative DCE-MRI can better predict pCR after neoadjuvant treatment for TNBC but not for the ER+/HER2- group.

    This study presents the results of a secondary analysis of data collected during a trial of reflexology that aimed to improve health-related quality of life (HRQOL) among women with advanced breast cancer in treatment. A comparison of HRQOL (functioning, symptoms, spirituality) of those with (n = 298) and without (n = 87) distant metastasis is presented. Following the intake interview, 385 women were randomised to reflexology, lay foot manipulation or conventional care control, and were interviewed again at weeks 5 and 11. Those with distant metastasis were older, had fewer comorbid conditions, and a smaller proportion were employed. Longitudinal analysis of HRQOL at intake, 5 and 11 weeks revealed that those with distant metastasis had lower functioning and more pain; however, no differences were found on fatigue, nausea, shortness of breath, sleep quality, anxiety, depressive symptoms or spirituality. Despite advanced disease, 56% of all women in this study were below the clinical screening cut-off for depressive symptoms. These findings may indicate that patients with advanced breast cancer have adapted emotionally and spiritually; however, the management of physical symptoms remains a priority. PMID:23252474

    Full Text Available There is substantial epidemiological evidence pointing to an increased incidence of breast cancer and morbidity in obese, prediabetic, and diabetic patients. In vitro studies strongly support metformin, a diabetic medication, in breast cancer therapy. Although metformin has been heralded as an exciting new breast cancer treatment, the principal consideration is whether metformin can be used as a generic treatment for all breast cancer types. Importantly, will metformin be useful as an inexpensive therapy for patients with comorbidity of diabetes and breast cancer? In general, meta-analyses of clinical trial data from retrospective studies in which metformin treatment has been used for patients with diabetes and breast cancer have a positive trend; nevertheless, the supporting clinical data outcomes remain inconclusive. The heterogeneity of breast cancer, confounded by comorbidity of disease in the elderly population, makes it difficult to determine the actual benefits of metformin therapy. Despite the questionable evidence available from observational clinical studies and meta-analyses, randomized phases I–III clinical trials are ongoing to test the efficacy of metformin for breast cancer.

    Full Text Available PURPOSE: The identification of tumor pathologic characteristics is an important part of breast cancer diagnosis, prognosis, and treatment planning but currently requires biopsy as its standard. Here, we investigated a noninvasive quantitative ultrasound method for the characterization of breast tumors in terms of their histologic grade, which can be used with clinical diagnostic ultrasound data. METHODS: Tumors of 57 locally advanced breast cancer patients were analyzed as part of this study. Seven quantitative ultrasound parameters were determined from each tumor region from the radiofrequency data, including mid-band fit, spectral slope, 0-MHz intercept, scatterer spacing, attenuation coefficient estimate, average scatterer diameter, and average acoustic concentration. Parametric maps were generated corresponding to the region of interest, from which four textural features, including contrast, energy, homogeneity, and correlation, were determined as further tumor characterization parameters. Data were examined on the basis of tumor subtypes based on histologic grade (grade I versus grade II to III. RESULTS: Linear discriminant analysis of the means of the parametric maps resulted in classification accuracy of 79%. On the other hand, the linear combination of the texture features of the parametric maps resulted in classification accuracy of 82%. Finally, when both the means and textures of the parametric maps were combined, the best classification accuracy was obtained (86%. CONCLUSIONS: Textural characteristics of quantitative ultrasound spectral parametric maps provided discriminant information about different types of breast tumors. The use of texture features significantly improved the results of ultrasonic tumor characterization compared to conventional mean values. Thus, this study suggests that texture-based quantitative ultrasound analysis of in vivo breast tumors can provide complementary diagnostic information about tumor histologic

    Objective. It is unknown whether advanced imaging (AI) is associated with higher quality breast cancer (BC) care. Materials and Methods. Claims and Surveillance Epidemiology and End Results data were linked for women diagnosed with incident stage I-III BC between 2002 and 2008 in western Washington State. We examined receipt of preoperative breast magnetic resonance imaging (MRI) or AI (defined as computed tomography [CT]/positron emission tomography [PET]/PET/CT) versus mammogram and/or ultrasound (M-US) alone and receipt of guideline concordant care (GCC) using multivariable logistic regression. Results. Of 5247 women, 67% received M-US, 23% MRI, 8% CT, and 3% PET/PET-CT. In 2002, 5% received MRI and 5% AI compared to 45% and 12%, respectively, in 2008. 79% received GCC, but GCC declined over time and was associated with younger age, urban residence, less comorbidity, shorter time from diagnosis to surgery, and earlier year of diagnosis. Breast MRI was associated with GCC for lumpectomy plus radiation therapy (RT) (OR 1.55, 95% CI 1.08–2.26, and p = 0.02) and AI was associated with GCC for adjuvant chemotherapy for estrogen-receptor positive (ER+) BC (OR 1.74, 95% CI 1.17–2.59, and p = 0.01). Conclusion. GCC was associated with prior receipt of breast MRI and AI for lumpectomy plus RT and adjuvant chemotherapy for ER+ BC, respectively. PMID:27525122

    International Nuclear Information System (INIS)

    To correlate the clinical features of women presenting with locally advanced breast cancer with event-free survival (EFS) and overall survival (OS) and to evaluate the patterns of relapse. Methods: A total of 200 patients presenting consecutively over 9 years with Stage III breast cancer were evaluated for age, socio-economic status (SES), tumour size and grade, number of involved lymph nodes, stage III sub-categories, estrogen and progesterone receptor (ER/PR) status, treatment profiles and responses, and sites of relapse. EFS and OS at 5 and 10 years were calculated. Results: Median age was 45 years. Poorly differentiated tumours were found in 127 patients, while 128 had larger tumours (T3 and T4). Eighty women had extensive nodal involvement (N2 and N3), and 86 had Stage IIIA tumours. Chemotherapy was given to 44 patients before surgery and one of these patients achieved pathological complete response. At 5 and 10 years, EFS was 25% and 7%, and OS was 52% and 31%, respectively. By Cox regression analysis, significant predictors of EFS included tumour size (95% CI 1.14-1.72), nodal involvement (95% CI 1.06-1.59) and ER/PR positive tumours (95% CI 1.08-2.29). Predictors of OS included nodal involvement (95% CI 0.98-3.3) and ER/PR positive tumours (95% CI 1.08-2.29). No patient in stage IIIC was alive at 10 years. Loco-regional disease was the most common site of relapse (28.5%). Conclusions: Locally advance breast cancer at our centre is associated with poor survival, and most patients relapsed by 5 years.

    The purpose of this work is to give practical guidelines for radiotherapy of locally advanced, inflammatory and metastatic breast cancer at first presentation. A comprehensive survey of the literature using the search phrases ''locally advanced breast cancer'', ''inflammatory breast cancer'', ''breast cancer and synchronous metastases'', ''de novo stage IV and breast cancer'', and ''metastatic breast cancer'' and ''at first presentation'' restricted to ''clinical trials'', ''randomized trials'', ''meta-analysis'', ''systematic review'', and ''guideline'' was performed and supplemented by using references of the respective publications. Based on the German interdisciplinary S3 guidelines, updated in 2012, this publication addresses indications, sequence to other therapies, target volumes, dose, and fractionation of radiotherapy. International and national guidelines are in agreement that locally advanced, at least if regarded primarily unresectable and inflammatory breast cancer should receive neoadjuvant systemic therapy first, followed by surgery and radiotherapy. If surgery is not amenable after systemic therapy, radiotherapy is the treatment of choice followed by surgery, if possible. Surgery and radiotherapy should be administered independent of response to neoadjuvant systemic treatment. In patients with a de novo diagnosis of breast cancer with synchronous distant metastases, surgery and radiotherapy result in considerably better locoregional tumor control. An improvement in survival has not been consistently proven, but may exist in subgroups of patients. Radiotherapy is an important part in the treatment of locally advanced and inflammatory breast cancer that should be given to all patients regardless to the intensity and effect of

    Nineteen patients with advanced refractory metastatic breast cancer no longer responsive to chemotherapy were treated in the first phase II efficacy trial of recombinant leukocyte A interferon (IFL-rA), a highly purified single molecular species of alpha interferon prepared by recombinant DNA methods. Patients received a previously determined maximum tolerated dose for this agent (50 X 10(6) U/m2 body surface area) by intramuscular injection three times weekly for up to 3 months. The symptoms of toxicity observed in this trial resemble those previously reported for alpha interferons and include fever, chills, fatigue, anorexia, and leukopenia. All patients required dose reductions, most often for reasons of severe fatigue. Of the 17 patients evaluable for tumor response, one patient had stable disease and 16 had evidence of tumor progression. We conclude that IFL-rA is not an active agent in the treatment of advanced, refractory breast cancer when used at a maximum tolerated dose on this treatment schedule. PMID:6342490

    Full Text Available There have been significant technological and technical advances in radiotherapy over the last 20 years. This paper presents the pertinent advances and examines their application in contemporary breast cancer (BC radiotherapy, particularly for reducing the long-term toxicity, using intensity-modulated radiation therapy, image-guided radiation therapy, and management of breathing motion. These modern technologies and techniques enable precise delivery of a highly conformal radiation dose distribution to the target volume in real-time, to optimise tumour control, and minimise treatment toxicity. They have been used for the treatment of BC in selected centres around the world. Although there is insufficient high-level evidence to support their routine application in BC at present, implementation of these technologies has been shown to be feasible, and could result in clinically meaningful long-term benefits for selected patients with BC.

    Medroxyprogesterone acetate (MPA) is one of the most commonly prescribed drugs for endocrine therapy of metastatic breast cancer. In this study, the serum MPA concentration was measured by high-performance liquid chromatography (HPLC) and evaluated for its usefulness in predicting the response in 79 cases of advanced or recurrent breast cancers. Overall, 29 patients (37%) achieved an objective response. The response rate correlated significantly with the oestrogen receptor (ER) status (P = 0.03), proliferative activity determined by DNA polymerase alpha (P = 0.04), the disease-free interval (DFI) (P = 0.05) and the serum MPA concentration (P < 0.001). Patients with ER-positive tumours, lower proliferative activity, a longer (DFI) or a higher serum MPA concentration responded more frequently. The mean serum MPA concentration in the responders with ER-positive tumours (P = 0.01) or tumours with a lower proliferative activity (P = 0.008) were significantly lower than in cases with ER-negative tumours or tumours with a higher proliferative activity, respectively. Cases with soft tissue metastases showed responses at significantly lower MPA concentrations (P = 0.003) than those with bone or visceral metastases. Furthermore, there was a dramatic decrease in the MPA concentration when a responder with a high concentration became unresponsive to the therapy. Thus, the serum MPA concentration is a determining factor for the response to treatment. PMID:9337682

    The efficacy of medroxyprogesterone acetate (MPA) therapy in controlling progressive measurable metastatic breast cancer was assessed in 61 patients. In addition serum MPA concentrations were measured by high performance liquid chromatography (HPLC) and subjective effects of treatment were monitored. Overall 24 patients (39.3%) achieved an objective response(2 complete responses [ CR ] and 22 partial responses [ PR ]). There was no significant relationships between response to therapy and menopausal status, metastatic sites, previous therapy, histological type, or disease-free interval. Patients with estrogen (ER) and progesterone (PgR) receptor-positive tumors responded more frequently. Significant differences in serum MPA concentrations were seen between responders and non-responders, objective tumor shrinkage being seen in patients with serum levels in excess of 55 ng/ml. There were few cases responding to the therapy with serum MPA concentrations lower than 25 ng/ml. The serum MPA levels significantly correlated with an improvement in the performance status and survival. Patients with serum MPA concentrations lower than 25 ng/ml had significantly poorer survival. There was a significant relationship between MPA level and dose per area of boby surface (mg/ m(2)) in cases with CR or PR or no change (NC). However, the serum levels of patients with progressive disease despite therapy were lower than the expected levels based on the body surface area. This study demonstrated that serum MPA concentration is a determining factor for therapeutic benefit in advanced or recurrent breast cancer. PMID:11091543

    Laser immunotherapy (LIT) was developed for the treatment of metastatic tumors. It combines local selective photothermal interaction and active immunological stimulation to induce a long-term, systemic anti-tumor immunity. During the past sixteen years, LIT has been advanced from bench-top to bedside, with promising outcomes. In our pre-clinical and preliminary clinical studies, LIT has demonstrated the capability in inducing immunological responses, which not only can eradicate the treated primary tumors, but also can eliminate untreated metastases at distant sites. Specifically, LIT has been used to treat advanced melanoma and breast cancer patients during the past five years. LIT was shown to be effective in controlling both primary tumors and distant metastases in late-stage patients, who have failed conventional therapies such as surgery, chemotherapy, radiation, and other more advanced approaches. The methodology and the development of LIT are presented in this paper. The patients' responses to LIT are also reported in this paper. The preliminary results obtained in these studies indicated that LIT could be an effective modality for the treatment of patients with late-stage, metastatic cancers, who are facing severely limited options.

    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.

    Objective:To explore and analyze the influences on neoadjuvant chemotherapy for serum tumor markers, invasion and metastasis related indexes of patients with advanced breast cancer.Methods:Patients with advanced breast cancer who had been treated in our hospital from February 2010 to February 2014 were randomly selected as research objects. They were randomly divided into control group (conventional surgical treatment group) and observation group (neoadjuant chemotherapy group). There were 32 cases of each group. Then, the changes of the different periods of serum tumor markers, invasion and metastasis related indexes in pretherapy and post-treatment of patients with advanced breast cancer in the two groups were observed.Results:The postoperative serum tumor markers, invasion and metastasis related indexes in different periods of the observation group were all lower than those of the control group, and the postoperative evaluation indexes of the two groups had significant difference. Conclusions:Neoadjuvant chemotherapy has great influences on serum tumor markers, invasion and metastasis related indexes of patients with advanced breast cancer and possesses high clinical application values.

  13. Breast cancers in elderly women

    International Nuclear Information System (INIS)

    Breast cancer is the most commonly diagnosed cancer and leading cause of cancer mortality in women worldwide. Nearly half of the global total of breast cancer cases occurs in patients > 65 years of age. Advanced age at the diagnosis of breast cancer is associated with more favorable tumor biology, as indicated by increased hormone sensitivity, attenuated HER- 2/neu overexpression, and lower grades and proliferative indices Elderly patients, however, are more likely to present with larger and more advanced tumors, and recent reports suggest that lymph node involvement increases with age. Elderly patients care less likely to be treated according to accepted treatment guidelines and under treatment can, as a consequence, have a strong negative impact on survival.Breast cancer in elderly patients represents a great social problem and is expected to remain one of the most common cancers in the next half century.

  14. Interleukin-19 in Breast Cancer

    Directory of Open Access Journals (Sweden)

    2013-01-01

    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.

    Blanchette, Phillip S; Pritchard, Kathleen I

    2015-01-01

    Bisphosphonates have played an important role in the treatment of breast cancer, mainly in patients with bone metastasis, by reducing the risk of fracture, spinal cord compression, and hypercalcemia. Both oral and intravenous products are available and have strong supporting clinical evidence. Zoledronic acid, the most frequently used intravenous agent, has traditionally been given on a monthly dosing schedule. A novel every-12-weeks maintenance dosing schedule shows clinical equivalence and promises to improve safety, affordability, and quality of care. The Early Breast Cancer Trialists' Collaborative Group has recently helped clarify the controversial benefit of bisphosphonates in the adjuvant setting. Based on their meta-analysis, we now have strong evidence supporting the use of adjuvant bisphosphonates to help prevent the development of bone metastasis in postmenopausal breast cancer patients, which leads to a significant improvement in breast cancer-specific survival. We eagerly await the full publication of this practice-changing study, which continues the incremental advance of the treatment of patients with breast cancer. PMID:25595283

  17. Prediction of sensitivity to anticancer agents for patients with advanced or recurrent breast cancer by Tc-99m sestamibi

    International Nuclear Information System (INIS)

    Tc-99m Sestamibi (99mTc-MIBI) is known to be a substrate of P-glycoprotein (P-gp) that effluxes the drugs out of cancer cells. The overexpression of P-gp involved in multidrug resistance phenomenon in patients with advanced or recurrent breast cancers was shown in the plasma membrane of breast cancer cells. In this study, we examined the usefulness of 99mTc-MIBI scintigraphy for the prediction of sensitivity to anticancer agents in 8 cases with advanced or recurrent breast cancer. The retrospective analysis showed that the sensitivity to the chemotherapy could be evaluated in 3 cases by 99mTc-MIBI scintigraphy, but in the other 5 cases 99mTc-MIBI scintigraphy was not eligible for the prediction of sensitivity. Two out of 3 cases showed over 50% in reduction rate of target tumors (PR) with higher accumulation of 99mTc-MIBI, while another case with PD showed lower. These results suggest that the accumulation of 99mTc-MIBI could be associated with the sensitivity to P-gp-related anticancer agents, and that the functional analysis of P-gp by 99mTc-MIBI might be useful for the prediction of responsiveness of chemotherapy in patients with breast cancer.

    Background Health utilities are increasingly incorporated in health economic evaluations. Different elicitation methods, direct and indirect, have been established in the past. This study examined the evidence on health utility elicitation previously reported in advanced/metastatic breast cancer and aimed to link these results to requirements of reimbursement bodies. Methods Searches were conducted using a detailed search strategy across several electronic databases (MEDLINE, EMBASE, Cochrane Library, and EconLit databases), online sources (Cost-effectiveness Analysis Registry and the Health Economics Research Center), and web sites of health technology assessment (HTA) bodies. Publications were selected based on the search strategy and the overall study objectives. Results A total of 768 publications were identified in the searches, and 26 publications, comprising 18 journal articles and eight submissions to HTA bodies, were included in the evidence review. Most journal articles derived utilities from the European Quality of Life Five-Dimensions questionnaire (EQ-5D). Other utility measures, such as the direct methods standard gamble (SG), time trade-off (TTO), and visual analog scale (VAS), were less frequently used. Several studies described mapping algorithms to generate utilities from disease-specific health-related quality of life (HRQOL) instruments such as European Organization for Research and Treatment of Cancer Quality of Life Questionnaire – Core 30 (EORTC QLQ-C30), European Organization for Research and Treatment of Cancer Quality of Life Questionnaire – Breast Cancer 23 (EORTC QLQ-BR23), Functional Assessment of Cancer Therapy – General questionnaire (FACT-G), and Utility-Based Questionnaire-Cancer (UBQ-C); most used EQ-5D as the reference. Sociodemographic factors that affect health utilities, such as age, sex, income, and education, as well as disease progression, choice of utility elicitation method, and country settings, were identified

  19. Radiation therapy planning with photons and protons for early and advanced breast cancer: an overview

    2006-07-01

    Full Text Available Abstract Postoperative radiation therapy substantially decreases local relapse and moderately reduces breast cancer mortality, but can be associated with increased late mortality due to cardiovascular morbidity and secondary malignancies. Sophistication of breast irradiation techniques, including conformal radiotherapy and intensity modulated radiation therapy, has been shown to markedly reduce cardiac and lung irradiation. The delivery of more conformal treatment can also be achieved with particle beam therapy using protons. Protons have superior dose distributional qualities compared to photons, as dose deposition occurs in a modulated narrow zone, called the Bragg peak. As a result, further dose optimization in breast cancer treatment can be reasonably expected with protons. In this review, we outline the potential indications and benefits of breast cancer radiotherapy with protons. Comparative planning studies and preliminary clinical data are detailed and future developments are considered.

    Breast Cancer, with a life-time prevalence of about 10-12%, is the most common cancer in women. In 2013, the actress Angelina Jolie, by announcing she had a double mastectomy, increased the awareness of a family history of breast and ovarian cancer and the treatment available to reduce the inherited risks. In Germany, each year about 25 out of 100,000 women (age-standardized according to European Standard) die of the disease. The number of newly diagnosed cases is about 72,000 per year. In comparison, many other countries record higher levels. Investing in the development of new therapies has therefore been key for many years. Prevention programs, such as the mammography screening are publicly touted, in both cases with the aim to reduce breast cancer mortality. To accurately assess the risk in underwriting, it is important to know about the risk factors for the development of breast cancer, as well as the latest advances in prevention, therapy and their prognostic classification. The following article provides an overview. PMID:25000626

  3. Sequencing chemotherapy and radiotherapy in locoregional advanced breast cancer patients after mastectomy – a retrospective analysis

    International Nuclear Information System (INIS)

    Combined chemo- and radiotherapy are established in breast cancer treatment. Chemotherapy is recommended prior to radiotherapy but decisive data on the optimal sequence are rare. This retrospective analysis aimed to assess the role of sequencing in patients after mastectomy because of advanced locoregional disease. A total of 212 eligible patients had a stage III breast cancer and had adjuvant chemotherapy and radiotherapy after mastectomy and axillary dissection between 1996 and 2004. According to concerted multi-modality treatment strategies 86 patients were treated sequentially (chemotherapy followed by radiotherapy) (SEQgroup), 70 patients had a sandwich treatment (SW-group) and 56 patients had simultaneous chemoradiation (SIM-group) during that time period. Radiotherapy comprised the thoracic wall and/or regional lymph nodes. The total dose was 45–50.4 Gray. As simultaneous chemoradiation CMF was given in 95.4% of patients while in sequential or sandwich application in 86% and 87.1% of patients an anthracycline-based chemotherapy was given. Concerning the parameters nodal involvement, lymphovascular invasion, extracapsular spread and extension of the irradiated region the three treatment groups were significantly imbalanced. The other parameters, e.g. age, pathological tumor stage, grading and receptor status were homogeneously distributed. Looking on those two groups with an equally effective chemotherapy (EC, FEC), the SEQ- and SW-group, the sole imbalance was the extension of LVI (57.1 vs. 25.6%, p < 0.0001). 5-year overall- and disease free survival were 53.2%/56%, 38.1%/32% and 64.2%/50%, for the sequential, sandwich and simultaneous regime, respectively, which differed significantly in the univariate analysis (p = 0.04 and p = 0.03, log-rank test). Also the 5-year locoregional or distant recurrence free survival showed no significant differences according to the sequence of chemo- and radiotherapy. In the multivariate analyses the sequence had no

    Full Text Available Metastatic breast cancer (BC remains an incurable disease and clinical benefit and prolongation of time to progression are the main end-points in advanced setting. A safe and feasible schedule of administration is the principal option in pre-treated and symptomatic patients, as in the elderly too. Oral vinorelbine represents a good choice for its toxicity profile and activity in anthracycline and taxane-pre-treated BC patients. A 20–30% response rate (RR can be obtained when used as single agent. In phase II trials, involving fit patients, and when oral vinorelbine is used in combination with other agents (e.g., capecitabine a RR of 50-60% has been observed. In HER2-positive BC a combination of oral vinorelbine and trastuzumab has a dramatic activity in first-line therapy and is a reasonable choice in trastuzumab pre-treated patients. In conclusion, oral vinorelbine represents a pivotal choice in advanced and pre-treated BC both as single agent and in combination with others.

  11. Disparities in the Use of Radiation Therapy in Patients With Local-Regionally Advanced Breast Cancer

    International Nuclear Information System (INIS)

    Background: Radiation therapy (RT) is indicated for the treatment of local-regionally advanced breast cancer (BCa). Hypothesis: We hypothesized that black and Hispanic patients with local-regionally advanced BCa would receive lower rates of RT than their white counterparts. Methods: The Surveillance Epidemiology and End Results database was used to identify white, black, Hispanic, and Asian patients with invasive BCa and ≥10 metastatic lymph nodes diagnosed between 1988 and 2005. Univariate and multivariate logistic regression evaluated the relationship of race/ethnicity with use of RT. Multivariate models stratified for those undergoing mastectomy or lumpectomy. Results: Entry criteria were met by 12,653 patients. Approximately half of the patients did not receive RT. Most patients were white (72%); the remainder were Hispanic (10.4%), black (10.3%), and Asian (7.3%). On univariate analysis, Hispanics (odd ratio [OR] 0.89; 95% confidence interval [CI], 0.79-1.00) and blacks (OR 0.79; 95% CI, 0.70-0.89) were less likely to receive RT than whites. On multivariate analysis, blacks (OR 0.76; 95% CI, 0.67-0.86) and Hispanics (OR 0.80; 95% CI, 0.70-0.90) were less likely than whites to receive RT. Disparities persisted for blacks (OR 0.74; 95% CI, 0.64-0.85) and Hispanics (OR 0.77; 95% CI, 0.67-0.89) who received mastectomy, but not for those who received lumpectomy. Conclusions: Many patients with local-regionally advanced BCa do not receive RT. Blacks and Hispanics were less likely than whites to receive RT. This disparity was noted predominately in patients who received mastectomy. Future efforts at improving rates of RT are warranted. Efforts at eliminating racial/ethnic disparities should focus on black and Hispanic candidates for postmastectomy RT.

    Breast cancer is the most common malignancy in women around the world. Breast cancer screening has been recognized as the primary approach to effectively improve the survival of female breast cancer. The most commonly used methods for breast cancer screening in China and other countries include mammography (MAM), ultrasonography (US), clinical breast examination (CBE) and magnetic resonance imaging (MRI). This paper summarizes the advantages and disadvantages of these screening techniques and reviewes the economic efficiency in health care of different screening techniques based on these examination approaches to provide some evidence for developing a breast cancer screening strategy with optimal cost-effectiveness for Chinese women.%乳腺癌是危害全世界女性健康最常见的恶性肿瘤.乳腺癌筛查是公认的能够有效提高女性乳腺癌生存率的主要方法.目前国内外常用的乳腺癌筛查手段包括乳房X线摄影术(钼靶X线摄影)、超声成像、临床乳腺检查和磁共振成像等.本文对这些筛查手段的优缺点进行了比较,并对基于这些手段建立的不同筛查方案在人群中的应用效果和卫生经济学评价进行综述,以期为建立符合中国国情的具有成本-效果的女性乳腺癌筛查策略提供参考和依据.

    Breast cancer is the leading cause of cancer deaths in Ghanaian women.To describes the characteristics of breast cancer patients attending the Komfo Anokye Teaching Hospital in Kumasi, Ghana.The study was conducted at the Komfo Anokye Teaching Hospital. Between July 1st 2004 and June 30th 2009 patients presenting with breast lumps were assessed by clinical examination, imaging studies and pathological examination. Relevant clinical and pathological were recorded prospectively data on all patients with microscopically proven breast cancer. The cancers were graded according to the modified Bloom-Richardson system. Tissue immunoperoxidase stains for oestrogen, progesterone receptors and c-erb2 oncogene were performed with commercially prepared antigens and reagents.Nineteen thousand four hundred and twenty – three (19,423) patients were seen during the study period. There were 330 (1.7%) patients with histologically proven breast cancer. The mean age was 49.1 years. A palpable breast lump was detected in 248 patients (75.2%). Two hundred and eighty –one patients (85.2%) presented with Stages III and IV , 271 (82.1%) invasive and 230 ( 85.2%) high grade carcinomas. Oestrogen and progesterone receptors were positive in 32 and 9 cases respectively. Her2 protein was positive in 11 cases. In Kumasi, as in other parts of Ghana, breast cancer affects mostly young pre-menopausal who present with advanced disease. The cancers have unfavourable prognostic features and are unlikely to respond to hormonal therapy. (au)

    In up to 75% of cases, advanced breast cancer patients eventually develop bone metastases with often debilitating skeletal-related events (SREs). Osteoclast inhibitors are commonly used as therapeutic mainstay with clinical studies showing superiority of denosumab over bisphosphonates (e.g., zoledronate) for the prevention of SREs. The present review discusses the adverse event profile of these agents, and addresses the prevention and management of untoward side effects. Adverse events associated with osteoclast inhibitors comprise osteonecrosis of the jaw and hypocalcemia. Hypocalcemia is more common with denosumab, particularly in severe renal dysfunction. During therapy, the appropriate prevention of these adverse events includes close attention to dental health, avoidance of invasive dental procedures, supplementation with calcium and vitamin D unless patients are hypercalcemic, and regular monitoring of relevant serum values. Relating to the risk of nephrotoxicity, bisphosphonates but not denosumab have been incriminated. Therefore, serum creatinine levels should be checked prior to each dose of zoledronate, and in severe renal dysfunction (creatinine clearance < 30 ml/min) zoledronate is contraindicated anyway. Acute-phase reactions are particularly linked to bisphosphonates. Consequently, if these adverse events predominate, switching to denosumab is recommended. PMID:25759613

    Past examinations of breast cancer treatment barriers have typically included registry, claims-based, and smaller survey studies. We examined treatment barriers using a novel, comprehensive, social media analysis of online, candid discussions about breast cancer. Using an innovative toolset to search postings on social networks, message boards, patient communities, and topical sites, we performed a large-scale qualitative analysis. We examined the sentiments and barriers expressed about breast cancer treatments by Internet users during 1 year (2/1/14-1/31/15). We categorized posts based on thematic patterns and examined trends in discussions by race/ethnicity (white/black/Hispanic) when this information was available. We identified 1,024,041 unique posts related to breast cancer treatment. Overall, 57 % of posts expressed negative sentiments. Using machine learning software, we assigned treatment barriers for 387,238 posts (38 %). Barriers included emotional (23 % of posts), preferences and spiritual/religious beliefs (21 %), physical (18 %), resource (15 %), healthcare perceptions (9 %), treatment processes/duration (7 %), and relationships (7 %). Black and Hispanic (vs. white) users more frequently reported barriers related to healthcare perceptions, beliefs, and pre-diagnosis/diagnosis organizational challenges and fewer emotional barriers. Using a novel analysis of diverse social media users, we observed numerous breast cancer treatment barriers that differed by race/ethnicity. Social media is a powerful tool, allowing use of real-world data for qualitative research, capitalizing on the rich discussions occurring spontaneously online. Future research should focus on how to further employ and learn from this type of social intelligence research across all medical disciplines. PMID:27339067

    Much effort has been made by researchers to elucidate the complex biology of breast cancer stem cells (BCSCs), a small subset of breast tumor cells that display stem cell properties, drive tumor initiation, and growth. In recent years, it has been suggested that BCSCs could be responsible for the process of metastasis and the development of drug resistance. These findings make the need to find the distinguishing blend of markers that can recognize only BCSCs of the utmost importance in order to be able to design new targeted therapies. This review will summarize BCSCs' main features as well as the cell surface markers that are currently used to identify them. PMID:26715540

  3. Clinical implications of recent studies using mTOR inhibitors to treat advanced hormone receptor-positive breast cancer

    International Nuclear Information System (INIS)

    Breast cancer is a leading cause of cancer-related death worldwide. Approximately 75% of breast cancer is hormone receptor-positive (HR+) and is managed with endocrine therapies. However, relapse or disease progression caused by primary or acquired endocrine resistance is frequent. Phosphatidylinositol-3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR)-mediated signaling is one of the molecular mechanisms leading to endocrine resistance. mTOR inhibitors that target the PI3K/Akt/mTOR pathway are the first of the targeted therapies to be evaluated in clinical trials to overcome endocrine resistance. Although the clinical trial with temsirolimus, an mTOR inhibitor, did not show any benefit when compared with endocrine therapy alone, a Phase II clinical trial with sirolimus has been promising. Recently, everolimus was approved in combination with exemestane by the US Food and Drug Administration for treating postmenopausal women with advanced HR+ breast cancer, based on the results of a Phase III trial. Therefore, everolimus represents the first and only targeted agent approved for combating endocrine resistance

    A randomized phase II study using mitomycin (MMC)/cisplatin (DDP) regimen with or without Kanglaite (KLT, a traditional Chinese medicine) as salvage treatment was conducted to exploit KLT's potential effects on patients with advanced breast cancer (ABC). Triweekly regimen consisted of mitomycin (8 mg/m(2)) administered intravenously on day 1, and cisplatin (25 mg/m(2)) intravenously on days 1 to 3. KLT (100 ml) was given intravenously per day on days 1 to 14 every 3 weeks. Between April 2006 and July 2007, 60 patients with a median age of 48 years were randomized into MMC/DDP with or without KLT treatment. In all, the objective response rate (ORR) was 17.5%. There were no significant differences between experimental and control treatments in terms of ORR (14.3% vs. 20.7%, p = 0.730), clinical benefit rates (24.1% vs. 28.6%, p = 0.468), median time to progression (TTP; 3.63 vs. 4.0, p = 0.872), and overall survival (OS; 7.17 vs. not reached, p = 0.120). The median TTP for patients with complete or partial responses was 6.0 months, but only 2.1 months for patients with stable or progressive disease (SD or PD; p = 0.028). While the median OS for patients who obtained clinical benefit from chemotherapy was not reached, that of patients with SD of no more than 6 months or PD was only 7.17 months (p = 0.004). There is no additional benefit when KLT is added to the MMC/DDP doublet in the management of ABC. Patients who obtained clinical benefit from chemotherapy had a longer TTP and OS. PMID:18711764

    Recent advances in genomic technology have led to considerable improvement in our understanding of the molecular basis that underpins breast cancer biology. Through the use of comprehensive whole genome genomic profiling by next-generation sequencing, an unprecedented bulk of data on driver mutations, key genomic rearrangements, and mechanisms on tumor evolution has been generated. These developments have marked the beginning of a new era in oncology called “personalized or precision medicine.” Elucidation of biologic mechanisms that underpin carcinogenetic potential and metastatic behavior has led to an inevitable explosion in the development of effective targeted agents, many of which have gained approval over the past decade. Despite energetic efforts and the enormous support gained within the oncology community, there are many obstacles in the clinical implementation of precision medicine. Other than the well-known biologic markers, such as ER and Her-2/neu, no proven predictive marker exists to determine the responsiveness to a certain biologic agent. One of the major issues in this regard is teasing driver mutations among the background noise within the bulk of coexisting passenger mutations. Improving bioinformatics tools through electronic models, enhanced by improved insight into pathway dependency may be the step forward to overcome this problem. Next, is the puzzle on spatial and temporal tumoral heterogeneity, which remains to be solved by ultra-deep sequencing and optimizing liquid biopsy techniques. Finally, there are multiple logistical and financial issues that have to be meticulously tackled in order to optimize the use of “precision medicine” in the real-life setting. PMID:27547031

    Full Text Available Background: Locally advanced breast cancer (LABC remains major clinical issue with regard to selection and duration of therapy since many years. Neoadjuvant chemotherapy (NACT is multimodality program, established to treat LABC. Many research tasks are ongoing to develop specific neoadjuvant chemotherapy regimen with specific duration to improve long-term control of LABC. Patients and Methods: Forty-seven patients diagnosed with LABC were Included and analyzed to compare the outcomes [pathological complete response (pCR, clinical response, overall response rate (ORR, disease control rate, overall survival and progression-free survival]. These patients treated with either combination of anthracycline and taxane-based chemotherapy or anthracycline-based chemotherapy. Results: There was no any statistical significance with respect to demographic data treated of patients between two arms (P > 0.05. Patients underwent TAC chemotherapy had pCR 20.8% whereas FAC/FEC chemotherapy patients had pCR 13% (P = 0.48. Higher ORR was noted in TAC chemotherapy arm (75% when compared with FAC/FEC chemotherapy arm (60.9% (P = 0.29. The study also shows better disease control rate in TAC chemotherapy arm (95.8% as compared to FAC/FEC chemotherapy arm (82.6%. There was no statistical significance in overall survival (P = 0.31 and progression-free survival (P = 0.51 between two arms. Conclusion: Despite of the superiority of combination of anthracycline and taxane-based chemotherapy over the anthracycline-based chemotherapy in the present study, further pivotal studies should be conducted to confirm the combination of anthracycline and taxane-based chemotherapy as a better neoadjuvant regimen for treatment of LABC tumors.

  9. The curability of breast cancer and the treatment of advanced disease

    International Nuclear Information System (INIS)

    Breast cancer represents a major health problem, with more than 1,000,000 new cases and 370,000 deaths yearly worldwide. In the last decade, in spite of an increasing incidence, breast cancer mortality has been declining in the majority of developed countries. This is the combined result of better education, widespread screening programmes and more efficacious adjuvant treatments. Better knowledge of breast cancer biology now allows the cosmetic, physical and psychological consequences of radical mastectomy to be spared in the majority of breast cancer patients. Use of the sentinel node technique is rapidly expanding and this will further reduce the extent and the consequences of surgery. Several clinico-pathological factors are used to discriminate between patients at low (<10%), average (10-40%) and high risk of relapse. Nodal status, tumour size, tumour grade and age are accepted universally as important factors to define risk categories. Newer factors such as uPA/PAI-1, HERer2-neu, proliferative indices and gene expression profile are promising and will allow better discrimination between patients at different risk. Endocrine manipulation with tamoxifen, ovarian ablation or both is the preferred option in the case of endocrine-responsive tumours. Tamoxifen administered for 5 years is the standard treatment for postmenopausal patients; tamoxifen plus ovarian ablation is more effective than tamoxifen alone for premenopausal women. Recent data demonstrate that, for postmenopausal patients, the aromatase inhibitors are superior to tamoxifen, with a different safety profile. At present, anastrozole can be used in the adjuvant setting in cases of tamoxifen intolerance or toxicity. Chemotherapy is the treatment of choice for steroid receptor-negative tumours. Polychemotherapy is superior to single agents and anthracycline-containing regimens are superior to CMF.

    Full Text Available More than 80% of women with breast cancer are now reported to be using complementary and alternative medicine (CAM therapies during conventional treatment. A randomized clinical trial (RCT of reflexology with late stage breast cancer patients serves as the data source for this article. The purposes were to investigate: (i reasons for refusal to participate in a RCT of reflexology; (ii the differences between those who completed the baseline interview and those who dropped out before baseline; and (iii the utility of the Palliative Prognostic Score (PPS as a prognostic screening tool in minimizing early attrition (before baseline from the trial. Eligible women (N = 400 approached at 12 cancer centers in the Midwest had advanced breast cancer, were on chemotherapy or hormonal therapy, and had a PPS of 11 or less. Comparisons of those who dropped out early (N = 33 to those who stayed in the trial (N = 240 were carried out using Wilcoxon rank, t-, chi-squared and Fisher's exact tests. The reasons of being “too sick” or “overwhelmed” were given by less than 12% of the women who refused to participate. There was a higher early dropout rate among black women compared to other (primarily white women (P = .01. Cancer recurrence and metastasis, age, and the PPS were not predictive of early retention of women. Specialized techniques may be needed to ensure black women remain in the trial once consented. Women with advanced disease were likely to enter and remain in the trial despite deterioration in health.

    Full Text Available Abstract Background Complementary and alternative medicine (CAM use is common among cancer patients. This paper reviews the use of CAM in a series of patients with locally advanced breast cancer (LABC. Methods Women with LABC attending a specialist clinic at a single Canadian cancer centre were identified and approached. Participants completed a self-administered survey regarding CAM usage, beliefs associated with CAM usage, views of their risks of developing recurrent cancer and of dying of breast cancer. Responses were scored and compared between CAM users and non-users. Results Thirty-six patients were approached, 32 completed the questionnaire (response rate 89%. Forty-seven percent of LABC patients were identified as CAM users. CAM users were more likely to be younger, married, in a higher socioeconomic class and of Asian ethnicity than non-users. CAM users were likely to use multiple modalities simultaneously (median 4 with vitamins being the most popular (60%. Motivation for CAM therapy was described as, "assisting their body to heal" (75%, to 'boost the immune system' (56% and to "give a feeling of control with respect to their treatment" (56%. CAM therapy was used concurrently with conventional treatment in 88% of cases, however, 12% of patients felt that CAM could replace their conventional therapy. Psychological evaluation suggests CAM users perceived their risk of dying of breast cancer was similar to that of the non-Cam group (33% vs. 35%, however the CAM group had less severe anxiety and depression. Conclusion The motivation, objectives and benefits of CAM therapy in a selected population of women with LABC are similar to those reported for women diagnosed with early stage breast cancer. CAM users display less anxiety and depression and are less likely to believe they will die of their breast cancer. However the actual benefit to overall and disease free survival has yet to be demonstrated, as well as the possible interactions with

  18. Contralateral breast cancer risk

    International Nuclear Information System (INIS)

    The use of breast-conserving treatment approaches for breast cancer has now become a standard option for early stage disease. Numerous randomized studies have shown medical equivalence when mastectomy is compared to lumpectomy followed by radiotherapy for the local management of this common problem. With an increased emphasis on patient involvement in the therapeutic decision making process, it is important to identify and quantify any unforeseen risks of the conservation approach. One concern that has been raised is the question of radiation- related contralateral breast cancer after breast radiotherapy. Although most studies do not show statistically significant evidence that patients treated with breast radiotherapy are at increased risk of developing contralateral breast cancer when compared to control groups treated with mastectomy alone, there are clear data showing the amount of scattered radiation absorbed by the contralateral breast during a routine course of breast radiotherapy is considerable (several Gy) and is therefore within the range where one might be concerned about radiogenic contralateral tumors. While radiation related risks of contralateral breast cancer appear to be small enough to be statistically insignificant for the majority of patients, there may exist a smaller subset which, for genetic or environmental reasons, is at special risk for scatter related second tumors. If such a group could be predicted, it would seem appropriate to offer either special counselling or special prevention procedures aimed at mitigating this second tumor risk. The use of genetic testing, detailed analysis of breast cancer family history, and the identification of patients who acquired their first breast cancer at a very early age may all be candidate screening procedures useful in identifying such at- risk groups. Since some risk mitigation strategies are convenient and easy to utilize, it makes sense to follow the classic 'ALARA' (as low as reasonably

    For women with hormone receptor-positive advanced breast cancer, endocrine therapies, including the selective estrogen receptor modulator tamoxifen, the aromatase inhibitors anastrozole, letrozole, and exemestane, and the selective estrogen receptor degrader fulvestrant, are recommended in clinical guidelines. The addition of targeted agents such as everolimus or palbociclib to aromatase inhibitors are also recommended as treatment options. Chemotherapy remains an option, although clinical guidelines have recommended these agents be reserved for patients with immediately life-threatening disease or if resistance to endocrine therapy is known or suspected. The present review has consolidated the tolerability profiles of the agents approved for use in the treatment of hormone receptor-positive advanced or metastatic breast cancer based on phase III registration trial data. Endocrine therapies are generally well tolerated, although the addition of targeted therapies to aromatase inhibitors or fulvestrant appears to increase the proportion of patients experiencing adverse events, and palbociclib and chemotherapy appear to be more closely associated with serious adverse events, including neutropenia.

    Full Text Available Cancer metastasis, resistance to therapies and disease recurrence are significant hurdles to successful treatment of breast cancer. Identifying mechanisms by which cancer spreads, survives treatment regimes and regenerates more aggressive tumours are critical to improving patient survival. Substantial evidence gathered over the last 10 years suggests that breast cancer progression and recurrence is supported by cancer stem cells (CSCs. Understanding how CSCs form and how they contribute to the pathology of breast cancer will greatly aid the pursuit of novel therapies targeted at eliminating these cells. This review will summarise what is currently known about the origins of breast CSCs, their role in disease progression and ways in which they may be targeted therapeutically.

  7. Possibility of conservative local treatment after combined chemotherapy and preoperative irradiation for locally advanced noninflammatory breast cancer

    International Nuclear Information System (INIS)

    Purpose: The aims of this prospective study were to evaluate the outcome and the possibility of breast conservation therapy for patients with locally advanced noninflammatory breast cancer after primary chemotherapy followed by external preoperative irradiation. Methods and Materials: Between April 1982 and June 1990, 97 patients with locally advanced nonmetastatic and noninflammatory breast cancer were treated. The median follow-up was 93 months from the beginning of treatment. The induction treatment consisted of four courses of chemotherapy (doxorubicin, vincristine, cyclophosphamide, 5-fluorouracil) followed by preoperative irradiation (45 Gy to the breast and nodal areas). A fifth course of chemotherapy was given after radiation therapy. Three different loco-regional approaches were proposed, depending on the tumoral response. In 37 patients (38%) with residual tumor larger than 3 cm in diameter or located behind the nipple or with bifocal tumors, mastectomy and axillary dissection were performed. Sixty other patients (62%) benefited from conservative treatment: 33 patients (34%) achieved complete remission and no surgery was done but additional radiation boost was given to the initial tumor bed; 27 patients (28%) who had a residual mass less than or equal to 3 cm in diameter were treated by wide excision and axillary dissection followed by a boost to the excision site. After completion of local therapy, all patients received a sixth course of chemotherapy. A maintenance adjuvant chemotherapy regimen without anthracycline was prescribed (12 monthly cycles). Results: The 5-year actuarial loco-regional relapse rate was 16% after radiotherapy alone, 16% following wide excision and radiotherapy, and 5.4% following mastectomy. The 5-year loco-regional relapse rate was significantly higher after conservative local treatment (wide excision and radiotherapy, and radiotherapy alone) than after mastectomy (p = 0.04). After conservative local treatment, the 5-year breast

    International Nuclear Information System (INIS)

    I have read with great interest khafagy et all s article in ENC1 2012:24:91-6 This small series needs explanations for following questions: 1- Thirteen cases with N0 have been operated by a complete axillary dissection. Would it be better to undertake sentinel lymph node biopsy (SLNB) in these cases? 2- The patients with periareolar tumor localization (half of the patients) underwent needlessly a pedicled flap operation instead of an advancement flap or simple rotation flap. They are simple and therefore less time-consuming onco plastic procedures. They do not require whole nippleareola complex excision. Therefore, advancement flaps or periareolar mastopexy [1] were more reasonable. 3- Ten patients with N2 represent locally advanced cancer of breast (Stage III). They should be treated by primary chemotherapy instead of surgery first. It needs explanation. 4- Four cases with N+ have not been given adjuvant chemotherapy. It should be explained. 5- The rates of good cosmetic results were the same for both patients and doctors. But in the literature, the rates of health professionals are nearly always lower than patients [2], It needs explanation. 6- The condition of contralateral breasts has not been presented. Is not there some cases requiring contralateral mastoplasty, reduction or any other cosmetic procedure? Kind regards.

  12. Early Toxicity in Patients Treated With Postoperative Proton Therapy for Locally Advanced Breast Cancer

    International Nuclear Information System (INIS)

    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

    Gemignani; Petrek

    1999-05-01

    BACKGROUND: The issue of pregnancy following the diagnosis and treatment of breast cancer is important because the incidence of breast cancer is increasing in women of childbearing age. The fact that many women are delaying childbearing, whether for educational, professional, or personal reasons, increases the number of women who will undergo breast cancer treatment before completing childbearing. METHODS: Data on pregnancy in breast cancer survivors are limited and consist only of retrospective data. This paper reviews the published literature on the influence of subsequent pregnancy on breast cancer, including three recent large-scale population-based studies. RESULTS: The survival of women with breast carcinoma who subsequently become pregnant is not reported to be decreased in any of the published series. However, several biases may be present that justify the concern regarding the conclusions. CONCLUSIONS: Further research on the safety of subsequent pregnancy after breast carcinoma treatment is needed. To address these issues, patients are currently being accrued for a large, prospective, multicenter study of young breast carcinoma patients. PMID:10758557

  16. Glutathione S-transferase M1 null genotype: lack of association with tumour characteristics and survival in advanced breast cancer

    International Nuclear Information System (INIS)

    Glutathione S-transferase (GST)M1, a member of the μ class GST gene family, has been shown to be polymorphic because of a partial gene deletion. This results in a failure to express the GSTM1 gene in 50-60% of individuals. Several studies have demonstrated a possible link with the GSTM1-null genotype and susceptibility to cancer. Furthermore, a GSTM1 isoenzyme has been positively associated with protective effect against mutagenic drugs, such as alkylating agents and anthracyclines. To determine whether GSTM1 polymorphisms are associated with tumour characteristics and survival in advanced breast cancer patients, and whether it may constitute a prognostic factor. We genotyped 92 patients receiving primary chemotherapy, which included cyclophosphamide, doxorubicine and 5-fluorouracil. The relationships between allelism at GSTM1 and clinicopathological parameters including age, menopausal status, tumour size, grade hormone receptors, involved nodes and p53 gene mutations were analysed. Of the patients with GSTM1-positive genotype, tissue samples obtained before and after treatment were available from 28 cases, allowing RNA extraction and GSTM1 expression by reverse transcription polymerase chain reaction. Relationships with clinical response to chemotherapy, and disease-free and overall survival were also evaluated. The data obtained was analysed using logistic regression to estimate the odds ratio and 95% confidence interval. Of 92 patients, 57.6% (n = 53) were classified as heritably GSTM1-deficient, and 42.4% (n = 39) were of the GSTM1-positive genotype. There were no statistically significant relationships between GSTM1-null genotype and the clinicopathological parameters analysed. No relationship was observed between GSTM1 RNA expression and objective clinical response to chemotherapy. Objective clinical response to chemotherapy was related only to clinical tumour size (P = 0.0177) and to the absence of intraductal carcinoma (P = 0.0013). GSTM1-null genotype

    2003-12-01

    This phase II trial studied the efficacy and toxicity of full dose paclitaxel plus vinorelbine, as salvage chemotherapy in patients with metastatic breast cancer resistant to anthracyclines. Patients received vinorelbine (30 mg/m2) followed 1 hour later by full dose paclitaxel (175 mg/m2) every 3 weeks for a maximum of 8 cycles or until disease progression. Because of the heavy pretreatment of the patients, prophylactic granulocyte-colony stimulating factor (5 microg/kg) was administered daily for 5-10 days. To minimize potentially cumulative neurotoxicity due to both agents, amifostine was given prior to chemotherapy. Thirty-four patients: 8 with tumors primary resistant and 26 with tumors recurring within 3-6 months after anthracycline treatment, were evaluable for efficacy and toxicity. Objective responses occurred in 11 patients [32%; 95% confidence interval (CI): 16.3-47.7%), all partial responses. Responses were observed in lung and liver. The median response duration was 4 months (range 3-7), median time to progression was 5 months (range 3-9) and median overall survival was 8 months (range 4-24). Neutropenia was dose limiting (35% grade 3-4 toxicity). The left ventricular ejection fraction, measured and followed in 18 patients, fell less than 20% below baseline level in 9 patients (50%), but only one patient developed congestive cardiac failure. The paclitaxel-vinorelbine regimen was moderately tolerated and moderately effective in poor prognosis breast cancer patients with visceral metastases and tumors resistant to anthracyclines. The combination at these doses and schedules should be considered in the design of regimens for advanced breast cancer. PMID:14998089

    We investigated the relationship between methylxanthine consumption and breast cancer using data from a case-control study which included 1,510 cases and 1,882 controls identified through a nation-wide breast cancer screening program. There was no evidence of a positive association between methylxanthine consumption and risk of breast cancer. In fact, there was some suggestion of a negative association, particularly in women diagnosed after age 50. In addition, there was no evidence of increased risk with past or recent methylxanthine consumption, or with the consumption of caffeine or specific beverages, most notably brewed or instant caffeinated coffee and tea.

    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.

    International Nuclear Information System (INIS)

    The therapy of early breast cancer has been changing during the last decennium. It requires a multi-disciplinary approach and in each of these disciplines improvements have been implemented. The result is that treatment schedules can now be adapted to specific subgroups. In this review early breast cancer is defined as operable disease, using the criteria set out by Haagensen. Emphasis is given to describing the new developments in prognostic criteria, since these form the basis for creating subgroups for specific treatment schedules. Distinction is made between the factors relating to growth rate and those relating to metastatic potential. Data on screening promises a beneficial effect of the implementation of screening in national health care programs. Important shifts are seen in treatment schedules; the place of postoperative radiotherapy after classic ablative treatment is being challenged, whereas it plays a major role in the new breast conserving therapy schedules. The data mentioned in the review suggest that a large proportion of 'operable' cases can be treated with breast conservation but details in the technique of breast conserving therapy are still under investigation. They form a major part of the coming prospective studies in breast cancer. Improvements in reconstruction techniques, creating better cosmetic results, make reconstruction more competitive with breast conserving therapy. The use of chemotherapy and endocrine manipulation in early breast cancer has now been clearly confirmed by the overview technique by the Peto-group, thanks to all efforts of individual trialists together.

    Objective: The aim of our study was to evaluate the ef icacy of 89Sr combined with Technetium [99Tc] Methylene-diphosphonate Injection (99Tc-MDP) in the treatment of cancer pain in the advanced breast cancers with bone metastases. Methods: A total of 80 patients with various degrees of bone pain due to multiple metastases of breast cancer were treated with 89Sr combined with 99Tc-MDP. 89Sr was given intravenously at 4mCi on day 1 during the 3-month schedule. After 7 days, 99Tc-MDP was given at 22 mg/day on days 1–10 during the 1-month schedule, for 3 to 6 months. Results: The ef ective rate of relieving pain was 83.75%. The ef ective rate of curing bone metastases was 81.25%. So there was a significant improvement in the quality of life of the patients. Conclusion: 89Sr combined with 99Tc-MDP are ef ective in the treatment of cancer pain in the breast cancers with bone metastasis, and can obviously repair the bone destruction caused by metastases, thereby improving the quality of life in advanced breast cancer patients with bone metastases.

    Viruses are the accepted cause of many important cancers including cancers of the cervix and anogenital area, the liver, some lymphomas, head and neck cancers and indirectly human immunodeficiency virus associated cancers. For over 50 years, there have been serious attempts to identify viruses which may have a role in breast cancer. Despite these efforts, the establishment of conclusive evidence for such a role has been elusive. However, the development of extremely sophisticated new experimental techniques has allowed the recent development of evidence that human papilloma virus, Epstein-Barr virus, mouse mammary tumor virus and bovine leukemia virus may each have a role in the causation of human breast cancers.

Incidence and mortality due to cancer, particularly breast cancer has been increasing for last 50 years, even though there is a lacuna in the diagnosis of breast cancer at early stages. According to World Health Organization (WHO) 2012 reports, breast cancer is the leading cause of death in women, accounting 23% of all cancer deaths. In Asia, one in every three women faces the risk of breast cancer in their lifetime as per reports of WHO...

    The BioScan System was developed by OmniCorder Technologies, Inc. at the Jet Propulsion Laboratory. The system is able to locate cancerous lesions by detecting the cancer's ability to recruit a new blood supply. A digital sensor detects infrared energy emitted from the body and identifies the minute differences accompanying the blood flow changes associated with cancerous cells. It also has potential use as a monitoring device during cancer treatment. This technology will reduce the time taken to detect cancerous cells and allow for earlier intervention, therefore increasing the overall survival rates of breast cancer patients.

    Full Text Available Trials with tamoxifen have clearly shown that the risk of developing oestrogen receptor positive breast cancer can be reduced by at least 50% with prophylactic agents. The current challenge is to find new agents which achieve this or better efficacy, but with fewer side effects. Recent results indicate that the SERM raloxifene has similar efficacy to tamoxifen, but leads to fewer endometrial cancers, gynecological symptoms, and thromboembolic events. Results for contralateral tumors in adjuvant trials suggest that aromatase inhibitors may be able to prevent up to 70%–80% of ER-positive breast cancers, and this is currently being investigated in two large prevention trials, one using anastrozole (IBIS-II and the other exemestane (MAP.3. New agents are needed for receptor negative breast cancer and several possibilities are currently under investigation.

    To compare the usefulness of mammography and clinical examination in the evaluation of residual cancer of locally-advanced breast carcinoma treated with neoadjuvant chemotherapy. Among 67 patients with locally advanced breast carcinoma who were treated with neoadjuvant chemotherapy, 18, aged 35-67 (mean, 48) years, underwent mammography before and after this therapy. The 18 sets of mammographs were analyzed retrospectively and compared with the results of clinical examination based on histologic diagnosis. On histologic examinations, 16 of 18 patients (89%) were found to have residual cancer, but in one of these 16, mammography did not show this same result. On mammography, residual cancer was found in 16 patients, but in one of this group, histologic examination did not reveal the same finding. Clinically, a complete response was shown by four patients, and a partial response by 11 ; three showed no response. On histolgogic examination, three of the four patients with complete clinical response were found to have residual cancer. Post-treatment mammographic findings showed that 11 patients had measurable mass ; all of these had residual cancer (positive predictive value : 100%). However, five of seven patients in whom no measurable mass was evident also had residual cancer. Seven of 8 patients in whom microcalcifications were seen on mammography were found to have residual cancer (positive predictive value : 88%). The sensitivity of mammography in predicting residual cancer was greater than that of clinical examination (94% vs 81%), even when microscopic residual cancer was considered as a complete response (92% vs 77%). The specificity of mammography was the same as that of clinical examination(50% vs 50%, 20% vs 20%). In evaluating residual cancer of locally-advanced breast carcinoma after neoadjuvant chemotheragy, mammography is more accurate and informative than clincal examination. In predicting residual cancer, however, it is not accurate enough to replace

    Full Text Available Abstract Background DNA-damage assays, quantifying the initial number of DNA double-strand breaks induced by radiation, have been proposed as a predictive test for radiation-induced toxicity. Determination of radiation-induced apoptosis in peripheral blood lymphocytes by flow cytometry analysis has also been proposed as an approach for predicting normal tissue responses following radiotherapy. The aim of the present study was to explore the association between initial DNA damage, estimated by the number of double-strand breaks induced by a given radiation dose, and the radio-induced apoptosis rates observed. Methods Peripheral blood lymphocytes were taken from 26 consecutive patients with locally advanced breast carcinoma. Radiosensitivity of lymphocytes was quantified as the initial number of DNA double-strand breaks induced per Gy and per DNA unit (200 Mbp. Radio-induced apoptosis at 1, 2 and 8 Gy was measured by flow cytometry using annexin V/propidium iodide. Results Radiation-induced apoptosis increased in order to radiation dose and data fitted to a semi logarithmic mathematical model. A positive correlation was found among radio-induced apoptosis values at different radiation doses: 1, 2 and 8 Gy (p Conclusions An inverse association was observed for the first time between these variables, both considered as predictive factors to radiation toxicity.

Patients and methods: Adult women diagnosed with stage III or IV breast cancer (index date between 2008 and 2012 were identified from MarketScan® databases containing medical and pharmacy claims for >40 million enrollees insured with >100 US health plans. Patients were followed until the earlier of the following: end of enrollment, inpatient death, or December 31, 2012. Study cohorts were women ± HER2-targeted agent use, HER2-targeted agent users' subgroups of stages III and IV, and age group. Pre- and postindex breast cancer treatments were compared among study cohorts. Overall survival was compared using log-rank tests. Cox proportional-hazards models were used to study the predictors of overall survival. Results: Of 30,660 eligible women, 14.4% received HER2-targeted agents. HER2-targeted agent users received more aggressive pre- and postindex cancer treatments compared to those with no HER2-targeted agents. HER2-targeted agents had higher rates of pre- and postindex breast cancer surgery, adjuvant/neoadjuvant chemotherapy, radiation therapy, chemotherapy, and biologics-based therapy. Among HER2-targeted agent users, younger women and those with stage III breast cancer received more aggressive treatments. After adjusting for clinically relevant patient characteristics, women receiving HER2-targeted agents had a 20% reduced risk of death compared to patients not receiving HER2-targeted agents.

    Full Text Available Nestin, an intermediate filament protein, has traditionally been noted for its importance as a neural stem cell marker. However, in recent years, expression of nestin has shown to be associated with general proliferation of progenitor cell populations within neoplasms. There is no reported study addressing nestin expression in T4 breast cancer patients. Thus, the aim of the present study was to investigate, through immunohistochemistry, the expression and distribution of nestin in T4 breast cancer, in order to determine its association with clinical and pathological parameters as well as with patients’ outcome. Nestin was detectable in tumoral cells and in endothelial cells of blood microvessels, and it is significantly expressed in triple-negative and in inflammatory breast cancer (IBC subgroups of T4 breast tumours. The Kaplan-Meier analysis showed that the presence of nestin in tumoral cells significantly predicted poor prognosis at 5-years survival (P=0.02 and with borderline significance at 10-years of survival (P=0.05 in T4 breast cancer patients. On the basis of these observations, we speculate that nestin expression may characterize tumours with an aggressive clinical behavior, suggesting that the presence of nestin in tumoral cells and vessels may be considered an important factor that leads to a poor prognosis. Further studies are awaited to define the biological role of nestin in the etiology of these subgroups of breast cancers.

    Full Text Available BACKGROUND : The response of locally advanced breast cancer (LABC to neoadjuvant chemotherapy (NACT offers these patients previously treated by mastectomy, the chance for breast conservation. AIM : This study aims to assess the feasibility of lumpectomy in patients with LABC treated by NACT, with residual tumor 5 cm. SETTINGS, DESIGN : Single group prospective study from August 2001 to June 2003 in a teaching hospital. MATERIALS AND METHODS : Thirty patients with LABC whose tumors reduced with NACT to 5 cm were included. Simulation lumpectomy was performed on the mastectomy specimens to achieve 1 to 2 cm clearance from tumor and hence margin negativity. Multiple sections of the inked margin were studied. STATISTICAL ANALYSIS : Margin positivity was correlated with patient factors. Chi square test and Fisher′s exact test used as appropriate. P value 0.05 was considered significant. RESULTS AND CONCLUSIONS : After three cycles of NACT, 4 patients (13% had complete clinical response including 2 with complete pathological response. Twenty-two (73% showed partial response and 4, no response. Fourteen out of thirty (47% had tumor involvement of margins. Tumors with post-chemotherapy size> 4 cm were margin positive in 10/13 (77%. Tumors with post-chemotherapy size>3 cm were margin positive in 13/24 (54%. Tumors with post-chemotherapy size 3 cm were margin negative in 5/6 (83%. Pre-chemotherapy tumor size and post-chemotherapy tumor size were significantly associated with margin positivity (P=0.003. Tumors in the subareolar location had significantly higher incidence of residual tumor in the nipple areola complex. (P=0.04. Margin positivity of lumpectomy on downstaged tumors can be reduced by removing the nipple areola complex in subareolar tumors and by limiting breast conservation to tumors with post-chemotherapy size 3 cm.

    Full text: Superficial hyperthermia in combination with radiotherapy represents very effective local treatment of locally recurrent breast cancer. We will present a group of patients treated in our institution since February 2003 to November 2004. The aim of this work is the evaluation of local response to the treatment in our group of patients. Since February 2003 to November 2004 we treated group of 32 women with locally recurrent breast cancer. 24 patients were treated for local recurrence, 5 patients were treated for supraclavicular lymph node metastasis and 3 patients were treated for locally advanced tumor. 27 patients were evaluable for local response and its duration. Hyperthermia was combined with radiotherapy. Radiotherapy was done on 6 MeV linear accelerator, usually using 2 tangential fields with wedges. Dose of radiotherapy was usually 50 Gy/25 fractions (only in the cases of reirradiation with large volume we applied 40 Gy/20 fr). Hyperthermia was done using Lund hyperthermia system for superficial microwave hyperthermia working on 434 MHz and was applied once a week, 5 to 6 applications during the course of radiotherapy, mainly immediately after radiotherapy, for 60 min. The temperature was measured using termistor probes superficially, minimally in the six points. We tried to achieve temperatures in the range from 42 to 43.5oC, but the actually measured temperatures were limited by the tolerance of patients. The anesthetics were not used. We achieved response in 26 from 27 patients. CR on the chest wall or in the supraclavicular region was achieved in 17 cases, PR in 9 cases and in 1 case was seen only stabilization of disease. Duration of response was in range from 3 to 24 months, with median of 9 months. We did not see any serious side effects resulting from hyperthermia treatment, only in the cases of reirradiation we observed slower healing of the post irradiation skin reaction. Superficial hyperthermia represents useful tool for the

    Radiotherapy improves local control in breast cancer (BC) patients which increases overall survival in the long term. Improvements in treatment planning and delivery and a greater understanding of BC behaviour have laid the groundwork for high-precision radiotherapy, which is bound to further improve the therapeutic index. Precise identification of target volumes, better coverage and dose homogeneity have had a positive impact on toxicity and local control. The conformity of treatment dose due to three-dimensional radiotherapy and new techniques such as intensity modulated radiotherapy makes it possible to spare surrounding normal tissue. The widespread use of dose-volume constraints and histograms have increased awareness of toxicity. Real time image guidance has improved geometric precision and accuracy, together with the implementation of quality assurance programs. Advances in the precision of radiotherapy is also based on the choice of the appropriate fractionation and approach. Adaptive radiotherapy is not only a technical concept, but is also a biological concept based on the knowledge that different types of BC have distinctive patterns of locoregional spread. A greater understanding of cancer biology helps in choosing the treatment best suited to a particular situation. Biomarkers predictive of response play a crucial role. The combination of radiotherapy with molecular targeted therapies may enhance radiosensitivity, thus increasing the cytotoxic effects and improving treatment response. The appropriateness of an alternative fractionation, partial breast irradiation, dose escalating/de-escalating approaches, the extent of nodal irradiation have been examined for all the BC subtypes. The broadened concept of adaptive radiotherapy is vital to high-precision treatments. PMID:27542556

  12. Constitutive gene expression profile segregates toxicity in locally advanced breast cancer patients treated with high-dose hyperfractionated radical radiotherapy

    International Nuclear Information System (INIS)

    Breast cancer patients show a wide variation in normal tissue reactions after radiotherapy. The individual sensitivity to x-rays limits the efficiency of the therapy. Prediction of individual sensitivity to radiotherapy could help to select the radiation protocol and to improve treatment results. The aim of this study was to assess the relationship between gene expression profiles of ex vivo un-irradiated and irradiated lymphocytes and the development of toxicity due to high-dose hyperfractionated radiotherapy in patients with locally advanced breast cancer. Raw data from microarray experiments were uploaded to the Gene Expression Omnibus Database http://www.ncbi.nlm.nih.gov/geo/ (GEO accession GSE15341). We obtained a small group of 81 genes significantly regulated by radiotherapy, lumped in 50 relevant pathways. Using ANOVA and t-test statistical tools we found 20 and 26 constitutive genes (0 Gy) that segregate patients with and without acute and late toxicity, respectively. Non-supervised hierarchical clustering was used for the visualization of results. Six and 9 pathways were significantly regulated respectively. Concerning to irradiated lymphocytes (2 Gy), we founded 29 genes that separate patients with acute toxicity and without it. Those genes were gathered in 4 significant pathways. We could not identify a set of genes that segregates patients with and without late toxicity. In conclusion, we have found an association between the constitutive gene expression profile of peripheral blood lymphocytes and the development of acute and late toxicity in consecutive, unselected patients. These observations suggest the possibility of predicting normal tissue response to irradiation in high-dose non-conventional radiation therapy regimens. Prospective studies with higher number of patients are needed to validate these preliminary results

  15. Radiation induced apoptosis and initial DNA damage are inversely related in locally advanced breast cancer patients

    International Nuclear Information System (INIS)

    DNA-damage assays, quantifying the initial number of DNA double-strand breaks induced by radiation, have been proposed as a predictive test for radiation-induced toxicity. Determination of radiation-induced apoptosis in peripheral blood lymphocytes by flow cytometry analysis has also been proposed as an approach for predicting normal tissue responses following radiotherapy. The aim of the present study was to explore the association between initial DNA damage, estimated by the number of double-strand breaks induced by a given radiation dose, and the radio-induced apoptosis rates observed. Peripheral blood lymphocytes were taken from 26 consecutive patients with locally advanced breast carcinoma. Radiosensitivity of lymphocytes was quantified as the initial number of DNA double-strand breaks induced per Gy and per DNA unit (200 Mbp). Radio-induced apoptosis at 1, 2 and 8 Gy was measured by flow cytometry using annexin V/propidium iodide. Radiation-induced apoptosis increased in order to radiation dose and data fitted to a semi logarithmic mathematical model. A positive correlation was found among radio-induced apoptosis values at different radiation doses: 1, 2 and 8 Gy (p < 0.0001 in all cases). Mean DSB/Gy/DNA unit obtained was 1.70 ± 0.83 (range 0.63-4.08; median, 1.46). A statistically significant inverse correlation was found between initial damage to DNA and radio-induced apoptosis at 1 Gy (p = 0.034). A trend toward 2 Gy (p = 0.057) and 8 Gy (p = 0.067) was observed after 24 hours of incubation. An inverse association was observed for the first time between these variables, both considered as predictive factors to radiation toxicity

    Purpose: Previous studies have demonstrated how imaging of the breast with patients lying prone using a supportive positioning device markedly facilitates longitudinal and/or multimodal image registration. In this contribution, the authors’ primary objective was to determine if there are differences in the standardized uptake value (SUV) derived from [{sup 18}F]fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) in breast tumors imaged in the standard supine position and in the prone position using a specialized positioning device. Methods: A custom positioning device was constructed to allow for breast scanning in the prone position. Rigid and nonrigid phantom studies evaluated differences in prone and supine PET. Clinical studies comprised 18F-FDG-PET of 34 patients with locally advanced breast cancer imaged in the prone position (with the custom support) followed by imaging in the supine position (without the support). Mean and maximum values (SUV{sub peak} and SUV{sub max}, respectively) were obtained from tumor regions-of-interest for both positions. Prone and supine SUV were linearly corrected to account for the differences in 18F-FDG uptake time. Correlation, Bland–Altman, and nonparametric analyses were performed on uptake time-corrected and uncorrected data. Results: SUV from the rigid PET breast phantom imaged in the prone position with the support device was 1.9% lower than without the support device. In the nonrigid PET breast phantom, prone SUV with the support device was 5.0% lower than supine SUV without the support device. In patients, the median (range) difference in uptake time between prone and supine scans was 16.4 min (13.4–30.9 min), which was significantly—but not completely—reduced by the linear correction method.

  19. Inheritance of proliferative breast disease in breast cancer kindreds

    International Nuclear Information System (INIS)

    Previous studies have emphasized that genetic susceptibility to breast cancer is rare and is expressed primarily as premenopausal breast cancer, bilateral breast cancer, or both. Proliferative breast disease (PBD) is a significant risk factor for the development of breast cancer and appears to be a precursor lesion. PBD and breast cancer were studied in 103 women from 20 kindreds that were selected for the presence of two first degree relatives with breast cancer and in 31 control women. Physical examination, screening mammography, and four-quadrant fine-needle breast aspirates were performed. Cytologic analysis of breast aspirates revealed PBD in 35% of clinically normal female first degree relatives of breast cancer cases and in 13% of controls. Genetic analysis suggests that genetic susceptibility causes both PBD and breast cancer in these kindreds. This study supports the hypothesis that this susceptibility is responsible for a considerable portion of breast cancer, including unilateral and postmenopausal breast cancer

  20. Advances in breast cancer treatment and prevention: preclinical studies on aromatase inhibitors and new selective estrogen receptor modulators (SERMs)

    International Nuclear Information System (INIS)

    Intensive basic and clinical research over the past 20 years has yielded crucial molecular understanding into how estrogen and the estrogen receptor act to regulate breast cancer and has led to the development of more effective, less toxic, and safer hormonal therapy agents for breast cancer management and prevention. Selective potent aromatase inhibitors are now challenging the hitherto gold standard of hormonal therapy, the selective estrogen-receptor modulator tamoxifen. Furthermore, new selective estrogen-receptor modulators such as arzoxifene, currently under clinical development, offer the possibility of selecting one with a more ideal pharmacological profile for treatment and prevention of breast cancer. Two recent studies in preclinical model systems that evaluate mechanisms of action of these new drugs and suggestions about their optimal clinical use are discussed

    Chemotherapy, endocrine therapy and molecular targeted therapy are vital means in the treatment of metastatic breast cancer (MBC), whose reasonable and standard applications are of great importance to prolong patients’ survival and improve the quality of life. The expressions of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER-2) present signiifcant differences between primary and metastatic breast cancer. However, these differences may affect the selection of MBC patients for therapeutic strategies and judgment on the prognosis. Hence, the relevant researches on variations of hormone receptors and HER-2 in primary and metastatic breast cancer, discordant causes of ER, PR and HER-2 expression in primary and metastatic lesions and clinical value of biopsy to the metastases are reviewed in the study.

  9. Progestins and breast cancer.

    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

Materials and Methods : We retrospectively reviewed the outcome of 141 patients with stage II to stage III carcinoma breast treated at Department of Radiotherapy, PGIMER, Chandigarh from 1998-2002. Mean age of the patients was 46 years, 49% of patients were premenopausal and 51% were postmenopausal. The tumor stage was T2 in 18%; T3 in 61% and T4 in 26% of the patients. NACT regimen given was FAC (5-fluorouracil, adriamycin and cyclophosphamide in 85% and CMF (cyclophosphamide, methotrexate and 5-Fu in 15% patients. Results : After NACT, surgery was possible in 95% patients. Conservative surgery was possible in 23% patients and mastectomy was done in 72% of patients. Pathological complete response (pCR was seen in 18% patients and pathological partial response (pPR in 69% of patients. Stable and progressive disease was seen in 6% and 7% of patients respectively. Adjuvant radiation therapy was given to 86% patients. Six percent patients developed progressive disease and 4% of patients did not turn up for radiation. Five year LRR was 6% and relapse free survival (RFS was 94%. Thirty-two (23% patients developed distant metastasis resulting in distant metastasis free survival of 77%. The factors that correlated positively with LRR on univariate analysis included tumor stage, stage and pathological nodal stage. However, on multivariate analysis, tumor stage and pathological nodal stage were significant. Factors that correlated for distant relapse were tumor stage, response to chemotherapy, type of surgery, extracapsular extension (ECE and tamoxifen therapy. On multivariate analysis only ECE was the significant factor that correlated with distant relapse free survival. Conclusion : Thus, tumor stage and pathological nodal stage remains the most important predictor of LRR

    Since several studies have demonstrated the inadequate diagnostic performance of mammography in high risk women, over the past two decades, different breast imaging tests have been evaluated as additional diagnostic methods to mammography, and the most relevant ones are the techniques that do not imply the use of X-rays, considering the young age of these patients and the higher radio-sensitivity. Breast dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) has risen growing interest not only because of the absence of use of X-rays, but also because it provides morpho-functional features, which may depict biological characteristics of breast tissues, including invasive and in situ cancers. Different multicenter non-randomized prospective studies aimed to evaluate breast DCE-MRI as an integral part of surveillance programs, agreed about the evidence that in high risk women screening with DCE-MRI is more effective than either mammography and/or ultrasound. Moreover, this modality leads to the identifications of cancers at a more favorable stage, allowing a real advantage in terms of tumor size and nodal involvement. The medical community is evaluating to suggest DCE-MRI alone as screening modality in high-risk women, as it was reported that in these cases the sensitivity of MRI plus conventional imaging was not significantly higher than that of MRI alone. Breast MRI is now recommended as part of screening program for high risk women by both European and American guidelines. PMID:26924173

  16. Preliminary report. Concomitant irradiation and paclitaxel as radiosensitizer to increase the operability of unresectable locally advanced breast cancer

    International Nuclear Information System (INIS)

    The objective of this non-randomized, single-arm pilot study was to investigate whether paclitaxel (50 mg/m2 body surface area) concomitantly administered with radiation (2 Gy/fr, total 50 Gy) could increase the operability of unresectable locally advanced breast cancer (LABC). Operability was assessed based on the Haagensen criteria, toxicity based on EORTC criteria, and response to therapy based on WHO criteria. Thus far 13 inoperable LABC patients have participated in the study as subjects in the treatment group, and 12 of the cases have been analyzable. As a result of radiopaclitaxel therapy, 10 of the 12 tumors became operable (>83%), and in 3 of the 10 patients there was no evidence of residual tumor. To date there have been no cases of local relapse in the treatment group. Given these results, the preliminary conclusions of the study are as follows: The results of radiochemotherapy, specifically with radiopaclitaxel, are quite promising as a method of treating inoperable LABC by reducing tumor size until it becomes operable. The efficacy and safety of the 50 mg/m2 body surface area dose of paclitaxel were adequate, allowing use of higher doses with the expectation of better results. The schedule of administration in this study yielded effective results. (K.H.)

  17. Prediction of response to chemotherapy in locally advanced breast cancer patients using Tc-99m MIBI scintimammography

    International Nuclear Information System (INIS)

    Locally advanced breast cancer is a common presentation in our part of the world. Down staging of the disease followed by surgery and further therapy has shown to prolong survival in such patients. Early prediction of response to therapy and chemo-resistance is of vital importance to ensure better outcome. The study was done to evaluate the possible role of Tc-99m MIBI scintimammography (MSM) in reliable and early prediction of response to therapy through tracer dynamics of the tumor. Response assessment through clinical criteria and other available modalities was also compared. 16 female patients were evaluated through dynamic and static prone MSM performed before and after two cycles of chemotherapy. Decay corrected washout curves were generated by drawing regions of interest (ROIs) all around the tumor. The tracer washout kinetics of the tumor were studied through half life estimation and tracer retention at 60 minute with reference to peak activity on pre and post therapy studies. Results were subjected to statistical analysis. There was a good correlation between the clinical assessment and dynamic MSM findings in good responders while the dynamic MSM was able to provide better information in poor responders. The results conclude that using tracer kinetics of MSM, early and reliable prediction of response to therapy and chemo-resistance may be possible

    Full Text Available Indigenous Māori women have a 60% higher breast cancer mortality rate compared with European women in New Zealand. We investigated differences in cancer biological characteristics and their impact on breast cancer mortality disparity between Māori and NZ European women.Data on 2849 women with primary invasive breast cancers diagnosed between 1999 and 2012 were extracted from the Waikato Breast Cancer Register. Differences in distribution of cancer biological characteristics between Māori and NZ European women were explored adjusting for age and socioeconomic deprivation in logistic regression models. Impacts of socioeconomic deprivation, stage and cancer biological characteristics on breast cancer mortality disparity between Māori and NZ European women were explored in Cox regression models.Compared with NZ European women (n=2304, Māori women (n=429 had significantly higher rates of advanced and higher grade cancers. Māori women also had non-significantly higher rates of ER/PR negative and HER-2 positive breast cancers. Higher odds of advanced stage and higher grade remained significant for Māori after adjusting for age and deprivation. Māori women had almost a 100% higher age and deprivation adjusted breast cancer mortality hazard compared with NZ European women (HR=1.98, 1.55-2.54. Advanced stage and lower proportion of screen detected cancer in Māori explained a greater portion of the excess breast cancer mortality (HR reduction from 1.98 to 1.38, while the additional contribution through biological differences were minimal (HR reduction from 1.38 to 1.35.More advanced cancer stage at diagnosis has the greatest impact while differences in biological characteristics appear to be a minor contributor for inequities in breast cancer mortality between Māori and NZ European women. Strategies aimed at reducing breast cancer mortality in Māori should focus on earlier diagnosis, which will likely have a greater impact on reducing breast

    2016-01-01

    Although survival rates among patients with breast cancer have improved in recent years, those diagnosed with advanced disease with distant metastasis face a 5-year survival rate of less than 25%, making the management of these patients an area still in significant need of continued research. Selecting the optimal treatment order from among the variety of currently available therapy options presents a relevant challenge for medical oncologists. With the understanding that the majority of patients with breast cancer and those who succumb to this disease have HR-positive disease, this review will focus on treatment options and treatment order in patients with HR-positive advanced breast cancer. While endocrine therapy is considered the preferred treatment for first-line therapy in HR-positive/HER2-negative breast cancer, selection of the specific agent depends on the menopausal status of the patient. Palbociclib, a cyclin-dependent kinase (CDK) 4/6 inhibitor, is also recommended as first-line treatment in patients with ER-positive/HER2-negative disease. In patients with endocrine therapy-resistant disease, specific strategies include sequencing of other antiestrogen receptor agents, or agents that target other molecular pathways. Future treatment strategies for patients with primary or secondary resistance to endocrine therapy for advanced disease are discussed. These strategies include first-line therapy with high-dose fulvestrant or everolimus (in combination with exemestane or letrozole or with other endocrine therapies), use of the PI3K inhibitors (e.g., buparlisib, alpelisib, pictilisib, taselisib), entinostat, CDK 4/6 inhibitors (e.g., palbociclib, ribociclib, abemaciclib), and novel selective estrogen receptor degradation agents that may enhance the targeting of acquired mutations in the ESR1 gene.

    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

  3. Postmastectomy electron-beam-rotation irradiation in locally advanced breast cancer. Prognostic factors of locoregional tumor control

    International Nuclear Information System (INIS)

    Background: Different radiotherapy techniques are used for postmastectomy irradiation. We review the results with the electron-beam-rotation technique in advanced breast cancer patients. Main endpoint was local tumor control. Patients and Methods: From 1990 to 1998 119 patients with adverse pathology features (pT3 17% of patients, pT4 42%, multicentricity 36%, pN≥3 positive nodes and/or pN1biii 81%, close margins 30%) underwent electron-beam-rotation irradiation of the chest wall with daily fractions of 2.0-2.5 Gy per day to 50 Gy total dose after modified radical mastectomy and axillary lymph nodes dissection. A local boost of 10 Gy and/or irradiation of locoregional lymph nodes were applied depending on the completeness of resection and lymph node involvement. Results: After a median follow-up of 73 months for patients at risk the 5-year local tumor control, local tumor control first event, disease-free, and overall survival were 82%, 92%, 57%, and 63% (Kaplan Meier analysis), respectively. Significant predictors of poor local tumor control were maximal tumor diameter ≥5 cm (p=0.01), 'close margins' or residual tumor (p<0.01), four or more involved axillary lymph nodes (p=0.02), two or more involved lymph node levels (p=0.04), negative estrogen receptor status (p=0.03), and high-grade histopathology (GIIb-III, p<0.01). The subgroup analysis showed a high local failure rate of 37% for high-grade (GIIb-III) and estrogen receptor negative tumors, whereas no local recurrence was found in low-grade (GI-IIa) and receptor positive tumors (p=0.01). The multivariate analysis revealed maximal tumor diameter ≥5 cm, four or more involved axillary lymph nodes and high-grade histopathology (GIIb-III) as independent predictors of poor local tumor control. Conclusion: In high-risk breast cancer patients postmastectomy irradiation with the electron-beam-rotation technique is an effective therapy, resulting in a 5-year local failure rate of 8%.

  4. Breast imaging technology: Recent advances in imaging endogenous or transferred gene expression utilizing radionuclide technologies in living subjects - applications to breast cancer

    International Nuclear Information System (INIS)

    A variety of imaging technologies is being investigated as tools for studying gene expression in living subjects. Two technologies that use radiolabeled isotopes are single photon emission computed tomography (SPECT) and positron emission tomography (PET). A relatively high sensitivity, a full quantitative tomographic capability, and the ability to extend small animal imaging assays directly into human applications characterize radionuclide approaches. Various radiolabeled probes (tracers) can be synthesized to target specific molecules present in breast cancer cells. These include antibodies or ligands to target cell surface receptors, substrates for intracellular enzymes, antisense oligodeoxynucleotide probes for targeting mRNA, probes for targeting intracellular receptors, and probes for genes transferred into the cell. We briefly discuss each of these imaging approaches and focus in detail on imaging reporter genes. In a PET reporter gene system for in vivo reporter gene imaging, the protein products of the reporter genes sequester positron emitting reporter probes. PET subsequently measures the PET reporter gene dependent sequestration of the PET reporter probe in living animals. We describe and review reporter gene approaches using the herpes simplex type 1 virus thymidine kinase and the dopamine type 2 receptor genes. Application of the reporter gene approach to animal models for breast cancer is discussed. Prospects for future applications of the transgene imaging technology in human gene therapy are also discussed. Both SPECT and PET provide unique opportunities to study animal models of breast cancer with direct application to human imaging. Continued development of new technology, probes and assays should help in the better understanding of basic breast cancer biology and in the improved management of breast cancer patients

The subjects were divided into two groups, based on the therapeutic regimen: Group A, 18 lesions, received an alternating TAM/MPA plus 5-FU chemotherapy, and Group B, 15 lesions, received this same chemoendocrine therapy combined with radiation (45 to 60 Gy for 4 to 6 weeks). In Group A, 4 out of 18 lesions (22.2%) responsed to the treatment, whereas in Group B, 10 out of 15 (66.7%) responded to the treatment (p=0.0265). Further, in Group A, only 2 lesions (11.1%) achieved a complete remission (CR), whereas in Group B, 9 lesions (60%) achieved a CR (p=0.0094). The incidence of leukopenia, however, was higher in Group B, but this did not affect the continuance of therapy. It was thus concluded that the combined therapy was more effective and contributed to the improvement of a greater number of the advanced and/or recurrent breast cancer cases. (author)

    Tamoxifen is a central component of the treatment of estrogen receptor (ER)-positive breast cancer as a partial agonist of ER. It has been clinically used for the last 30 years and is currently available as a chemopreventive agent in women with high risk for breast cancer. The most challenging issue with tamoxifen use is the development of resistance in an initially responsive breast tumor. This review summarizes the roles of ER as the therapeutic target of tamoxifen in cancer treatment, clin...

    The identification of modifiable lifestyle factors that could reduce the risk of breast cancer is a research priority. Despite the enormous chemo preventive potential of green tea and compelling evidence from animal studies, its role in breast cancer development in humans is still unclear. Part of the uncertainty is related to the relatively small number of epidemiological studies on green tea and breast cancer and that the overall results from case-control studies and prospective cohort stud...

  12. Original P53 status predicts for pathological response in locally advanced breast cancer patients treated preoperatively with continuous infusion 5-fluorouracil and radiation therapy

    International Nuclear Information System (INIS)

    Purpose/Objective: 1) To test feasibility of preoperative continuous infusion (c.i.) 5-Fluorouracil (5-FU) and radiation (RT) in locally advanced breast cancer. 2) To study clinical and pathological response rates of 5-FU and radiation. 3) To attempt preliminary correlations between biological probes and pathological response. Methods and Materials: Previously untreated, locally advanced breast cancer patients were eligible: only patients who presented with T3/T4 tumors that could not be resected with primary wound closure were eligible, while inflammatory breast cancer patients were excluded. The protocol consisted of preoperative c.i. infusion 5-FU, 200 mg/m2/day with radiotherapy, 50 Gy at 2 Gy fractions to the breast and regional nodes. At mastectomy, pathological findings were classified based on persistence of invasive cancer: pathological complete response (pCR) = no residual invasive cells in the breast and axillary contents; pathological partial response (pPR) = presence of microscopic foci of invasive cells in either the breast or nodal specimens; no pathological response (pNR) = pathological persistence of tumor. For each patient pretreatment breast cancer biopsies were analyzed by immunohistochemistry for nuclear grade, ER/PR hormonal receptors, her2/neu and p53 overexpression. Results: Thirty-five women have completed the protocol and are available for analysis. 5-FU was interrupted during radiation in 10 of 35 patients because of oral mucositis in 8 patients, cellulitis in 1, and patient choice in another. Objective clinical response rate before mastectomy was 71% (25 of 35 patients): 4 CR, 21 PR. However, in all 35 patients tumor response was sufficient to make them resectable with primary wound closure. Accordingly, all patients underwent modified radical mastectomy: primary wound closure was achieved in all patients. At mastectomy there were 7 pCR (20%), 5 pPR (14%) and the remaining 23 patients (66%) had pathological persistence of cancer (p

    The systemic therapy of breast cancer has also changed profoundly during the last 60 years, and in this time the integration of treatment modalities involve a major area of investigation. The dosimetry of breast cancer presents different complications which can range from the Physician's handling of the neoplasia up to the simple aspects of physical simulation, contour design, radiation fields, irregular surfaces and computer programs containing mathematical equations which differ little or largely with the reality of the radiation distribution into the volume to be irradiated. We have studied the problem using two types of measurements to determine how the radiation distribution is in irregular surfaces, and designing an easier skill to be used with each patient, in order to optimize the treatment with respect to the simulation and verification process.

    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.

    2013-11-01

    Eribulin mesylate is a synthetic analog of halichondrin B (a polyether macrolide isolated from a marine sponge). It is a nontaxane microtubule dynamics inhibitor with a novel mechanism of action. It is the first drug that has demonstrated an improvement in overall survival as a single agent compared with the physician's choice of currently available treatments in locally advanced or metastatic breast cancer, previously treated with anthracyclines and taxanes. It has shown a good manageable tolerability profile. This drug has been approved by the US FDA and by the EMA for patients with locally advanced or metastatic breast cancer who have received at least two chemotherapeutic regimens for advanced/metastatic disease. Prior therapy should have included an anthracycline and a taxane in either the adjuvant or metastatic setting unless patients were not suitable for these treatments. The aim of this article is to describe the mechanism of action, pharmacokinetics, pharmacodynamics and the most relevant clinical trials in the development of this drug. PMID:24161305

Triple negative breast cancer (TNBC is a recently identified biological variant with aggressive tumor behavior and poor prognosis. Data of hormonal status from the Indian population is scarce due to financial constraints in performing immunohistochemistry evaluation. The present study aims to prospectively analyze receptor status of all breast cancer patients and identify TNBC and compare their clinical profile and short term survival with other non-TNBC group. Materials and methods: All cytologically and histopathologically confirmed cases of carcinoma breast were prospectively enrolled. In a longitudinal study at tertiary care hospital in central India based on the hormonal status, they were further divided into TNBC and other groups. Comparison of risk factors, clinical profile and short-term survival was carried out. Results: A total 85 patients were enrolled and of them 37 (43.7% were TNBC. On comparing risk factors ie, age, age at menarche, total reproductive age, age at first child birth, and menopausal status – no statistical significance was observed between the TNBC and non-TNBC groups. But on comparison of clinical profile TNBC tumors were significantly large with majority of patients presenting as locally advanced breast cancer (83%. No statistical difference was observed in axillary lymph node status between two groups. TNBC tumors were histologically more aggressive (grade 3 compared to other groups. No statistically significant difference was observed in short term overall survival but all three deaths were observed in the TNBC group only and two local recurrences after surgery were observed in the TNBC group. Conclusion: TNBC forms a large proportion of carcinoma breast patients in a central

    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. PMID:26528110

    With mammography firmly established as an integral part of efforts to reduce breast cancer mortality, many believe it is time to concentrate on prevention. Part of the multifaceted approach to preventing and treating this disease is unraveling its molecular, genetic and physiological makeup. Another aspect is ensuring that women have the information they need to make informed decisions about screening and treatment. Studies also point to the influence of nutrition, exercise, medicines and a patient's adherence to screening on cancer risk and recovery. PMID:20445140

    The enumeration of circulating tumor cells (CTCs) provides important prognostic values in patients with metastatic breast cancer. Recent studies indicate that individual CTCs form clusters and these CTC-clusters play an important role in tumor metastasis. We aimed to assess whether quantification of CTC-clusters provides additional prognostic value over quantification of individual CTCs alone. In 115 prospectively enrolled advanced-stage (III and IV) breast cancer patients, CTCs and CTC-clusters were counted in 7.5 ml whole blood using the CellSearch system at baseline before first-line therapy. The individual and joint effects of CTC and CTC cluster counts on patients' progression-free survival (PFS) were analyzed using Cox proportional hazards modeling. Of the 115 patients, 36 (31.3 %) had elevated baseline CTCs (≥5 CTCs/7.5 ml) and 20 (17.4 %) had CTC-clusters (≥2 CTCs/7.5 ml). Patients with elevated CTCs and CTC-clusters both had worse PFS with a hazard ratio (HR) of 2.76 [95 % confidence interval (CI) 1.57-4.86, P log-rank = 0.0005] and 2.83 (1.48-5.39, P log-rank = 0.001), respectively. In joint analysis, compared with patients with IBC), the most aggressive form of breast cancer with the poorest survival. Baseline counts of both individual CTCs and CTC-clusters were associated with PFS in advanced-stage breast cancer patients. CTC-clusters might provide additional prognostic value compared with CTC enumeration alone, in patients with elevated CTCs. PMID:26573830

    Breast cancer in men is a rare disease, accounting for approximately 1% of all breast cancer cases. Although the epidemiologic literature regarding female breast cancer is extensive, relatively little is known about the etiology of male breast cancer (MBC). This review is intended to summarize the existing body of evidence on genetic and epidemiologic risk factors for breast cancer in men. Overall, the epidemiology of MBC presents similarities with the epidemiology of female breast cancer. Major genetic factors associated with an increased risk of breast cancer for men include BRCA2 mutations, which are believed to account for the majority of inherited breast cancer in men, Klinefelter syndrome, and a positive family history. Suspected genetic factors include AR gene mutations, CYP17 polymorphism, Cowden syndrome, and CHEK2. Epidemiologic risk factors for MBC include disorders relating to hormonal imbalances, such as obesity, testicular disorders (e.g., cryptorchidism, mumps orchitis, and orchiectomy), and radiation exposure. Suspected epidemiologic risk factors include prostate cancer,prostate cancer treatment, gynecomastia, occupational exposures (e.g., electromagnetic fields, polycyclic aromatic hydrocarbons, and high temperatures), dietary factors (e.g., meat intake and fruit and vegetable consumption), and alcohol intake.

  4. Breast cancer therapies weighed

    International Nuclear Information System (INIS)

    Even as the National Institutes of Health came under fire last week for giving short shrift to women in the institute's basic and clinical research programs, the report of a recent NIH consensus conference points up the need for more research on how to treat early breast cancer. Although the experts were able to agree on the best surgical treatment for women with early breast cancer, they couldn't resolve the more controversial issue of whether the patients should subsequently receive systemic treatment - chemotherapy or hormone therapy - to prevent recurrence of their disease. The panel reaffirmed that the removal of the lump and nearby lymph nodes, followed by irradiation, is just as effective as a mastectomy. But then came the contentious question: should women with early breast cancer, especially those without detectable lymph node metastases, receive drug therapy to prevent recurrence of the disease? Currently, 70% of such cancers are successfully treated with surgery and radiation alone. For this reason, about 2 years ago, the National Cancer Institute issued a clinical alert saying that addition treatment with drugs or hormones is a credible therapeutic option worthy of careful attention for all early stage patients. This pronouncement engendered a storm of criticism. A consensus panel concluded that in cases where tumors are 1 centimeter or less in diameter and no lymph nodes are affected, the likelihood of recurrence is so small that the benefits of adjuvant therapy would be insignificant. But for the patients with larger tumors, the panel concluded that the decision is an individual one that depends on personal preferences and a variety of prognostic factors that can help to indicate whether a woman is at high risk of having a recurrence and should therefore have adjuvant therapy

AIMS : To evaluate the implication of SDI and identify key drugs for loco-regional response in locally advanced breast cancer (LABC. Settings and design: This retrospective study was based on audit of records of LABC patients who had received neoadjuvant chemotherapy (NACT. MATERIAL AND METHODS : Actual unit dose-intensity (UDI of each drug and corresponding SDI of every doxorubicin (n=116 cycles or non-doxorubicin (n=110 cycles based NACT received by 42 patients of LABC were summated. Cumulative dose-intensity (CDI for individual drugs and cumulative SDI (CSDI for the entire course of NACT were estimated and correlated with quantum of primary tumor, axillary and supraclavicular nodal responses. STATISTICAL ANALYSIS USED : Two-sided chi-square, t-test, step-wise regression was used. RESULTS : Dose-response curve between CSDI and corresponding responses for both primary and lymph nodes were sigmoid in shape for both doxorubicin or non-doxorubicin based NACT. Curves were best fitted using a cubic fit for all patients (r2 = 0.82, 0.84 and 0.93 for primary tumor, axillary and supraclavicular lymph nodes respectively. CSDI emerged as an important prognosticators for both primary (P< 0.001 and nodal (P< 0.001 responses. Individually, CDI of 5-fluorouracil for primary (P< 0.001, CDIs of doxorubicin (P< 0.001 and methotrexate (P=0.006 for axillary nodes and CDI of cyclophosphamide (P=0.001 for supraclavicular nodes were significant. CONCLUSIONS : Loco-regional responses in LABC are dependent on CSDI of NACT regimen. Drugs for high-dose intensification protocols could be identified and chosen based on the impact of CDI of individual drugs in NACT.

    A prospective randomized study was carried out to evaluate the effectiveness of MPA in the treatment of breast cancer by comparing low dose (600 mg/day) with high dose (1,200 mg/day) of MPA. In 35 evaluable cases, the response rate to treatment was 40.0% (8/20) with low dose MPA and 26.7% (4/15) with high dose MPA. There was no significant difference between the two groups. The serum MPA concentration measured by high-performance liquid chromatography (HPLC) assay was 23.2 +/- 17.6 ng/ml in the low-dose group and 89.5 +/- 56.7 ng/ml in the high-dose group. Intrapatient variability in serum MPA concentration was relatively stable, but interpatient variability was large. No correlation was found between the response rate and serum MPA concentration. The above results indicate that a low dose of MPA (600 mg/day) is a useful treatment with high effectiveness and safety in advanced and recurrent breast cancer patients. Though no exact data on the optimal serum concentration could not be obtained, it was obvious that a successful response cannot be expected from a serum MPA concentration of less than 17 ng/ml, which was the average serum concentration in NC and PD patients of the low-dose group.

    Large operable or locally advanced breast cancers (BCs) are usually treated with neoadjuvant chemotherapy (CT) before surgery. However, there is no evidence to support an improvement in efficacy with dose-dense (DD) CT in this setting. We, therefore, carried out a meta-analysis to investigate whether DD-CT was more effective than the reference (every 3 weeks anthracyclines±taxanes) standard-dose CT as neoadjuvant treatment for BC. We searched Pubmed, SCOPUS, EMBASE, the Web of Science, CINAHL, and the Cochrane Central Register of Controlled Trials for randomized trials comparing conventional versus DD neoadjuvant CT for BC. Odds ratios (ORs) for pathologic complete responses (ypT0N0M0: pCR) and hazard ratios (HRs) of death and recurrence [overall survival (OS), and disease-free survival (DFS)] were estimated and pooled. A QUADAS-2 report for all studies included in the final analysis was tabulated for the risk of bias and applicability. A total of six randomized trials fulfilled the inclusion criteria. The pooled rates of the pCR were 13.5 and 9.2% in the experimental and control arms. A significant increase in the pCR [OR=1.55, 95% confidence interval (CI) 1.18-2.02, P=0.001] was noted with neoadjuvant DD-CT. However, the patients who received DD-CT did not have significantly better DFS and OS rates (DFS: HR=0.88, 95% CI 0.76-1.01, P=0.06; OS: HR=0.89, 95% CI 0.78-1.02, P=0.08). Even with the limitation of a relatively short follow-up period, this meta-analysis shows that DD neoadjuvant CT, despite not leading to a significant increase in survival, increases by 46.7% the possibility of achieving a pCR in operable and locally advanced BC. This treatment should thus be considered one of the backbone treatments of choice when neoadjuvant therapy is planned. PMID:27058707

  16. Prognostic value of the 99mTc-Isonitrile washout rate in neoadjuvant chemotherapy in patients with locally advanced breast cancer

    International Nuclear Information System (INIS)

    Full text: Neoadjuvant chemotherapy is the pre-surgical treatment of choice in patients with locally advanced breast tumor for better disease control and breast conservation. Resistance to chemotherapy may be seen in about 18%-51% of the cancers. The term multi drug resistance (MDR) is commonly used to indicate the expression of the transmembrane glycoprotein (P-glycoprotein). This protein removes some very important chemotherapeutic drugs from inside the cell and is responsible for the clinical manifestation of the MDR. The knowledge of MDR before the initiation of chemotherapy can help choosing the best treatment. 99mTc-Isonitrile is a radiotracer largely used in nuclear medicine. It enters cells, is identified by the P-glycoprotein as a substrate and is, therefore, expelled from the neoplastic cell. Various studies have demonstrated direct correlation between the 99mTc-Isonitrile efflux, P-glycoprotein expression and MDR. On the other hand, 99mTc-Isonitrile retention in the tumor suggests chemosensitivity. The objective of this study was to monitor the response to neoadjuvant chemotherapy in breast cancer by the use of 99mTc-Sestamibi scintimammography and its washout rate in a pilot study. Five patients with locally advanced breast cancer were subjected to neoadjuvant chemotherapy. Inclusion criteria were locally advanced tumor, biopsy results, no distant metastasis, and completion of the whole chemotherapy protocol. Exclusion criteria were any previous cancer treatment or other primary tumor. All the patients underwent 99mTc-Sestamibi scintimammography before and after completion of the chemotherapy protocol. For scintimammography, 740MBq of radiotracer was injected in the arm contra lateral to the side of lesion. Planar images were acquired at 10 and 240 minutes, in anterior supine position as well as in both lateral projections in prone position. Regions of interest of same size were drawn over the tumor and in the contra lateral breast to correct for

    OBJECTIVES: When estimating the decline in breast cancer mortality attributable to screening, the challenge is to provide valid comparison groups and to distinguish the screening effect from other effects. In Funen, Denmark, multidisciplinary breast cancer management teams started before screening...... was introduced; both activities came later in the rest of Denmark. Because Denmark had national protocols for breast cancer treatment, but hardly any opportunistic screening, Funen formed a "natural experiment", providing valid comparison groups and enabling the separation of the effect of screening...... from other factors. METHODS: Using Poisson regression we compared the observed breast cancer mortality rate in Funen after implementation of screening with the expected rate without screening. The latter was estimated from breast cancer mortality in the rest of Denmark controlled for historical...

    A review is presented of recent advances in optical imaging and spectroscopy and the use of light for addressing breast cancer issues. Spectroscopic techniques offer the means to characterize tissue components and obtain functional information in real time. Three-dimensional optical imaging of the breast using various illumination and signal collection schemes in combination with image reconstruction algorithms may provide a new tool for cancer detection and monitoring of treatment.

  20. Resolving breast cancer heterogeneity by searching reliable protein cancer biomarkers in the breast fluid secretome

    International Nuclear Information System (INIS)

    One of the major goals in cancer research is to find and evaluate the early presence of biomarkers in human fluids and tissues. To resolve the complex cell heterogeneity of a tumor mass, it will be useful to characterize the intricate biomolecular composition of tumor microenvironment (the so called cancer secretome), validating secreted proteins as early biomarkers of cancer initiation and progression. This approach is not broadly applicable because of the paucity of well validated and FDA-approved biomarkers and because most of the candidate biomarkers are mainly organ-specific rather than tumor-specific. For these reasons, there is an urgent need to identify and validate a panel of biomarker combinations for early detection of human tumors. This is especially important for breast cancer, the cancer spread most worldwide among women. It is well known that patients with early diagnosed breast cancer live longer, require less extensive treatment and fare better than patients with more aggressive and/or advanced disease. In the frame of searching breast cancer biomarkers (especially using nipple aspirate fluid mirroring breast microenvironment), studies have highlighted an optimal combination of well-known biomarkers: uPA + PAI-1 + TF. When individually investigated they did not show perfect accuracy in predicting the presence of breast cancer, whereas the triple combination has been demonstrated to be highly predictive of pre-cancer and/or cancerous conditions, approaching 97-100% accuracy. Despite the heterogeneous composition of breast cancer and the difficulties to find specific breast cancer biomolecules, the noninvasive analysis of the nipple aspirate fluid secretome may significantly improve the discovery of promising biomarkers, helping also the differentiation among benign and invasive breast diseases, opening new frontiers in early oncoproteomics

    Advanced or metastatic breast cancer is an incurable disease with high mortality rate worldwide and about 20% of breast cancers overexpress and amplify the human epidermal growth factor receptor 2 (HER2). Achievements in targeted therapy have benefited people during the past decades. Trastuzumab emtansine (T-DM1), a novel antibody-drug conjugate playing a powerful role in anti-tumor activity, not only blocks the HER2 signaling pathways, but also disturbs the microtubule dynamics. To access the efficacy and safety of T-DM1, we analyzed 9 clinical trials on T-DM1. Results showed that fatigue (0.604, 95% CI 0.551, 0.654), nausea (0.450, 95% CI 0.365, 0.537), increased transaminases (0.425, 95% CI 0.353, 0.500) and thrombocytopenia (0.383, 95% CI 0.322, 0.448) occurred more frequently in participants with single T-DM1. In controlled trials, increased transaminases (OR = 4.040, 95% CI 1.429, 11.427), thrombocytopenia (OR = 8.500, 95% CI 3.964, 18.226) and fatigue (OR = 1.288, 95% CI 1.041, 1.593) were statistically significant. Only thrombocytopenia appeared as severe adverse event (grade ≥ 3) in single-arm and control-arm studies. Meanwhile, T-DM1 stabilized cancer and prolonged life with notable improved progression-free survival (PFS) and overall survival (OS). In conclusion, it is a safe and effective agent in advanced or metastatic breast cancer, but should be carefully applied on patients with severe hepatic and neurological disease. PMID:26979925

  4. Contribution of 18-FDG-PET/TC in the handling of the locally advanced stadiums of breast cancer

    International Nuclear Information System (INIS)

    Conventional imaging modalities provide only morphological details and do not provide information on the metabolic status of a lesion, which is very important in differentiating a benign from a malignant lesion. Early diagnosis and reliable imaging assessment of response to treatment are essential in the clinical management of breast cancer. Positron Emission Tomography (PET) has been widely shown to be highly useful for the diagnosis of palpable masses, for staging, for obtaining long-term prognostic information, and for demonstrating tumour response to chemotherapy at an early phase or after completion of treatment in patient with breast cancer. Twenty-three consecutive female patients with primary breast carcinoma (T3/T4,N2,M0) were prospectively recruited for AT--TDG and tumour 18F-IDG update (standardized update value, SUV was used as a metabolic indicator. There was a positive relationship between tumour metabolic and response to chemotherapy and pathological conditions SUV provides an index of regional tracer uptake and a reduced SUV are indicative of tumour regression.

    PURPOSE AND METHODS Our secondary analyses compared survival with eribulin versus capecitabine in various patient subgroups from a phase 3, open-label, randomized study. Eligible women aged ≥18 years with advanced/metastatic breast cancer and ≤3 prior chemotherapies (≤2 for advanced/metastatic disease), including an anthracycline and taxane, were randomized 1:1 to intravenous eribulin mesylate 1.4 mg/m2 on days 1 and 8 or twice-daily oral capecitabine 1250 mg/m2 on days 1–14 (21-day cycles). RESULTS In the intent-to-treat population (eribulin 554 and capecitabine 548), overall survival appeared longer with eribulin than capecitabine in various subgroups, including patients with human epidermal growth factor receptor 2-negative (15.9 versus 13.5 months, respectively), estrogen receptor-negative (14.4 versus 10.5 months, respectively), and triple-negative (14.4 versus 9.4 months, respectively) disease. Progression-free survival was similar between the treatment arms. CONCLUSIONS Patients with advanced/metastatic breast cancer and human epidermal growth factor receptor 2-, estrogen receptor-, or triple-negative disease may gain particular benefit from eribulin as first-, second-, and third-line chemotherapies. TRIAL REGISTRATION (PRIMARY STUDY) This study reports the subgroup analyses of eribulin versus capecitabine from a phase 3, open-label, randomized study (www.clinicaltrials.gov; ClinicalTrials.gov identifier: NCT00337103).

  8. Aluminium, antiperspirants and breast cancer.

    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.

    Adjuvant therapies for breast cancer have achieved great success in recent years and early breast cancer is now a curable or chronic disease. Targeted therapies, including endocrine therapy and human epidermal growth factor receptor-2 targeted therapy, marked a new era of breast cancer treatment. However, except for chemotherapy, an efficient drug treatment to improve the overall survival of breast cancer patients is still lacking for triple negative breast cancer. Furthermore, a certain proportion of breast cancer patients present with resistance to drug therapy, making it much more difficult to control the deterioration of the disease. Recently, altered energy metabolism has become one of the hallmarks of cancer, including breast cancer, and it may be linked to drug resistance. Targeting cellular metabolism is becoming a promising strategy to overcome drug resistance in cancer therapy. This review discusses metabolic reprogramming in breast cancer and the possible complex mechanism of modulation. We also summarize the recent advances in metabolic therapy targeted glycolysis, glutaminolysis and fatty acids synthesis in breast cancer. PMID:26862496

  10. Breast Cancer Chemoprevention: Old and New Approaches

    Full Text Available In 1976, Sporn has defined chemoprevention as “the use of pharmacologic or natural agents that inhibit the development of invasive breast cancer either by blocking the DNA damage that initiates carcinogenesis, or by arresting or reversing the progression of premalignant cells in which such damage has already occurred.” Although the precise mechanism or mechanisms that promote a breast cancer are not completely established, the success of several recent clinical trials in preventive settings in selected high-risk populations suggests that chemoprevention is a rational and an appealing strategy. Breast cancer chemoprevention has focused heavily on endocrine intervention using selective estrogen receptor modulators (SERMs and aromatase inhibitors (AIs. Achieving much success in this particular setting and new approaches as low-dose administration are actually under investigations in several topics. Unfortunately, these drugs are active in prevention of endocrine responsive lesions only and have no effect in reducing the risk of estrogen-negative breast cancer. Thus, recently new pathways, biomarkers, and agents likely are to be effective in this subgroup of cancers and were put under investigation. Moreover, the identification of new potential molecular targets and the development of agents aimed at these targets within cancer have already had a significant impact on advanced cancer therapy and provide a wealth of opportunities for chemoprevention. This paper will highlight current clinical research in both ER-positive and ER-negative breast cancer chemoprevention, explaining the biologic effect of the various agents on carcinogenesis and precancerous lesions, and finally presenting an excursus on the state-of-the-art about new molecular targets under investigations in breast cancer settings.

    Introduction MicroRNAs (miRNAs) are small non-coding RNA that plays a vital role in cancer progression. Neo-adjuvant chemotherapy (NAC) has become the standard of care for locally advanced breast cancer. The aim of this study was to evaluate miRNA alterations during NAC using multiple samples of tissue and serum to correlate miRNA expression with clinico-pathological features and patient outcomes. Methods Tissue and serum samples were collected from patients with locally advanced breast cancer undergoing NAC at four time points: time of diagnosis, after the first and fourth cycle of doxorubicin/cyclophosphamide treatment, and after the fourth cycle of docetaxel administration. First, we evaluated the miRNA expression profiles in tissue and correlated expression with clinico-pathological features. Then, a panel of four miRNAs (miR-451, miR-3200, miR-21, and miR-205) in serum samples was further validated using quantitative reverse-transcription polymerase chain reaction (RT-qPCR). The alterations in serum levels of miRNA, associations with clinical and pathological responses, correlation with clinico-pathological features, and survival outcomes were studied using Friedman, Mann-Whitney U, and Spearman, Wilcoxon signed-ranks tests. P≤0.05 was considered statistically significant. Results We analyzed 72 tissue samples and 108 serum samples from 9 patients and 27 patients, respectively. MicroRNA expression profiling of tumor versus normal tissue revealed more than 100 differentially expressed miRNAs. Serum miR-451 levels were significantly decreased during treatment, and higher serum levels were associated with improved clinical and pathological responses and disease-free survival. This is one of the early reports on miR-3200 in response to treatment in breast cancer, as serum levels of miR-3200 found to decline during NAC, and higher serum levels were associated with lower residual breast cancer burden and relapse rates at time of diagnosis.

    2016-01-01

    Breast cancer, one of the most common cancers in women, has various treatment modalities. Neoadjuvant therapy (NAT) has been used in many clinical trials because it is easy to evaluate the treatment response to therapeutic agents in a short time period; consequently, NAT is currently a standard treatment modality for large-sized and locally advanced breast cancers, and its use in early-stage breast cancer is becoming more common. Thus, chances to encounter breast tissue from patients treated with NAT is increasing. However, systems for handling and evaluating such specimens have not been established. Several evaluation systems emphasize a multidisciplinary approach to increase the accuracy of breast cancer assessment. Thus, detailed and systematic evaluation of clinical, radiologic, and pathologic findings is important. In this review, we compare the major problems of each evaluation system and discuss important points for handling and evaluating NAT-treated breast specimens. PMID:27068026

  19. Accuracy of MRI for estimating residual tumor size after neoadjuvant chemotherapy in locally advanced breast cancer: Relation to response patterns on MRI

    International Nuclear Information System (INIS)

    Background. This study evaluated the accuracy of magnetic resonance imaging (MRI) for estimating residual tumor size after neoadjuvant chemotherapy in patients with locally advanced breast cancer and assessed whether the tumor pattern on MRI after chemotherapy influenced the accuracy of the MRI measurement of the residual tumor size. Patients and methods. Fifty patients who received neoadjuvant chemotherapy with doxorubicin and docetaxel for locally advanced breast cancer were evaluated with MRI before and after chemotherapy. We compared the residual tumor size measured by MRI with the pathologically determined size and investigated the influence of the residual tumor pattern on MRI (shrinkage, nest or rim, and mixed) and pathologic characteristics on the accuracy of the MRI measurement. Results. The correlation coefficient between the residual tumor sizes determined by MRI and by pathology was 0.645. The MRI measurement agreed with the pathologically determined size in 36 patients (72%) and disagreed in 14 patients (28%), overestimating the size in 13 (26%) and underestimating the size in one (2%). Disagreement appeared to be more frequent in the cases showing a nest or rim pattern than in those exhibiting a shrinkage pattern, although this was not statistically significant (p=0.119). Conclusions. MRI is an accurate method for predicting the extent of residual tumor after neoadjuvant chemotherapy; however, it may overestimate the residual disease, especially in cases showing a nest or rim tumor pattern and in those having combined lesions with ductal carcinoma in situ or multiple scattered nodules after neoadjuvant chemotherapy

The metabolic syndrome (MS) is a constellation of biochemical abnormalities including visceral adiposity, hyperglycemia, hyperinsulinemia, dyslipidemia and high blood pressure. The components of the MS have all been related to late-stage disease and even to a poor prognosis of breast cancer through multiple interacting mechanisms. In this review, we aim to present a summary of recent advances in the understanding of the contribution of the MS to breast cancer with the emphasis on the role of biomarkers of the MS in the prognosis of breast cancer.

    Objective: To evaluate clinical effects of Shenqi Fuzheng Injection (参芪抉正注射液) in the neoadjuvant chemotherapy for local advanced breast cancer and the effects on T-lymphocyte subsets. Methods: During the period from 2000 to 2005, 126 patients with local advanced breast cancer were treated with the neoadjuvant chemotherapy. They were randomly divided into the following two groups: a control group of 61 cases treated by chemotherapy alone and a study group of 65 cases treated by chemotherapy plus Shenqi Fuzheng Injection. All the cases of both groups were given the CEF (CTX 500 mg/m2, d1, 8; EPI 40 mg/m2, d1, 8; and 5-Fu 500 mg/m2, d1,8) regimen. The clinical effects, the effects on T-lymphocyte subgroup and NK cells, and the toxic side effects were observed. Results: All the patients completed two cycles of the chemotherapy, and the efficacy and the toxic side effects were evaluated. For the primary tumor in the breast, the total effective rate was 69.2% (45/65) in the study group and 49.2% (30/61) in the control group with a statistically significant difference in the intergroup comparison (χ2=5.251, P=0.022, < 0.05). There was no progression of the disease in both the groups, and there were no grade IV toxic side effects in the two groups. The major toxic responses were myelosuppression and gastrointestinal reaction, which were milder in the study group than the control group, and with a shorter recovery course in the former than the latter. Besides, an obvious rise of the T-lymphocyte subgroup and NK cells was found in the study group after the neoadjuvant chemotherapy, with a very significant difference from the controls (P<0.01). Conclusions: Shenqi Fuzheng Injection can improve and regulate immune function of the patients with local advanced breast cancer given the neoadjuvant chemotherapy, and therefore it can enhance the curative effect and reduce the side effect as well.

    Male breast cancer (MaleBC) is a rare disease, accounting for development; low-penetrance gene mutations (i.e. CHEK-2) are more common but involve a lower risk increase. About 90% of all male breast tumors have proved to be invasive ductal carcinomas, expressing high levels of hormone receptors with evident therapeutic returns. The most common clinical sign of BC onset in men is a painless palpable retroareolar lump, which should be evaluated by means of mammography, ultrasonography and core biopsy or fine needle aspiration (FNA). To date, there are no published data from prospective randomized trials supporting a specific therapeutic approach in MaleBC. Tumor size together with the number of axillary nodes involved are the main prognostic factors and should guide the treatment choice. Locoregional approaches include surgery and radiotherapy (RT), depending upon the initial clinical presentation. When systemic treatment (adjuvant, neoadjuvant and metastatic) is delivered, the choice between hormonal and or chemotherapy (CT) should depend upon the clinical and biological features, according to the FBC management guidelines. However great caution is required because of high rates of age-related comorbidities. PMID:19427229

    Full Text Available Background. Tumour characteristics are the most important prognostic factors in breast cancer. Patient-related factors such as young age at diagnosis, obesity, and smoking behaviour may also modify disease outcome. Due to the absence of a unique definition for “young age breast cancer” and the resulting variation in disease management, findings on the association between young age and prognosis of breast cancer are controversial. Methods. This study included 1500 patients with a primary diagnosis of breast cancer in six Iranian hospitals from 5 provinces. We modelled the relative excess risk (RER of breast cancer death to age at diagnosis and tumour characteristics. Results. Excess risks of death were observed for stage IV disease and poorly differentiated tumours: RER of 4.3 (95% CI: 1.05–17.65 and 3.4 (95% CI: 1.17–9.87, respectively. “Older” patients, particularly those aged 50 and over, presented more often with advanced and poorly differentiated tumours (P=0.001. After adjustment for stage, histological grade, Her-2 expression, estrogen and progesterone receptors, and place of residency, breast cancer mortality was not significantly different across age groups. Conclusion. We conclude that there is no prognostic effect of age at diagnosis of breast cancer among breast cancer patients treated at cancer centres in different parts of Iran; young and relatively old women have similar risks of dying from breast cancer.

    Full Text Available Breast cancer accounts for more than 20% Indian women in India. The mortality is still higher than the cervix cancer even though the descriptive etiology, early diagnosis tools and best therapies are available for the breast cancer. As for as Indian women concerns, most of them are not aware about the myths and facts of hidden anatomy of breast, cause, diagnosis followed by the treatment required to cure the evil disease i.e. breast cancer. This review mainly focuses on etiology of breast cancer, types of breast cancers i.e. Ductal carcinoma in situ (DCIS, Invasive ductal carcinoma, Lobular carcinoma in situ (LCIC, Invasive lobular carcinoma, Inflammatory breast disease, various diagnostic tools used to characterize the type of diseases, various methods to detect the stages of cancers, advanced imaging techniques (Ultrasound, MRI,CT Scan, PET Scan etc. and other biopsy tests required to assess the breast cancer followed by the better treatment to improve the morbidity. The extensive literature review done on this topic and this literature review would be helpful to the community updating about the breast cancer, how one can diagnose the evil disease on time and get the best therapy available to live life happily.

    Full Text Available Malgorzata Banys,1,2 Andreas D Hartkopf,1 Natalia Krawczyk,1 Tatjana Kaiser,1 Franziska Meier-Stiegen,1 Tanja Fehm,1 Hans Neubauer11Department of Obstetrics and Gynecology, University of Tuebingen, Tuebingen, Germany; 2Department of Obstetrics and Gynecology, Marienkrankenhaus Hamburg, Hamburg, GermanyAbstract: Tumor dormancy describes a prolonged quiescent state in which tumor cells are present, but disease progression is not yet clinically apparent. Breast cancer is especially known for long asymptomatic periods, up to 25 years, with no evidence of the disease, followed by a relapse. Factors that determine the cell's decision to enter a dormant state and that control its duration remain unclear. In recent years, considerable progress has been made in understanding how tumor cells circulating in the blood interact and extravasate into secondary sites and which factors might determine whether these cells survive, remain dormant, or become macrometastases. The mechanisms of tumor cell dormancy are still not clear. Two different hypotheses are currently discussed: tumor cells persist either by completely withdrawing from the cell cycle or by continuing to proliferate at a slow rate that is counterbalanced by cell death. Because dormant disseminated tumor cells may be the founders of metastasis, one hypothesis is that dormant tumor cells, or at least a fraction of them, share stem cell-like characteristics that may be responsible for their long half-lives and their suggested resistance to standard chemotherapy. Therefore, knowledge of the biology of tumor cell dormancy may be the basis from which to develop innovative targeted therapies to control or eliminate this tumor cell fraction. In this review, we discuss biological mechanisms and clinical implications of tumor dormancy in breast cancer patients.Keywords: tumor dormancy, disseminated tumor cell, circulating tumor cell, targeted therapy

    International Nuclear Information System (INIS)

    Three patients developed bilateral breast cancer at 10 to 24 years after mantle irradiation for locally or systemically advanced Hodgkin's disease (HD). Four of the six cancers in the three patients were detected only by mammography. Pathologically, five of the cancers were intraductal carcinomas (four with an invasive component) with one being a lobular carcinoma. Five of the six lesions were Stage I pathologically without evidence of axillary nodal involvement. It is recommended that female patients with Hodgkin's disease who have received mantle irradiation as part of the therapy for their Hodgkin's disease and who are observed for 10 or more years after completion of mantle irradiation be considered at risk for the development of breast cancer. Such patients should be monitored appropriately by routine bilateral mammograms to increase the early detection of early stage lesions

    Full Text Available Abstract Background Young breast cancer patients have a lower rate of survival than old breast cancer patients due to being diagnosed at advanced stages. Breast self-examination makes women more "breast aware", which in turn may lead to an earlier diagnosis of breast cancer. The purpose of this study was to investigate knowledge and practice of breast self-examination and to determine knowledge of risk factors for breast cancer among high school students. Methods This is a descriptive and cross-sectional study. It was conducted in a high school in Manisa, Turkey. The study sample included 718 female high school students. A socio-demographic characteristics data form, knowledge of breast self examination and risk factors for breast cancer form and breast self examination practice form were used to collect data. Results The female high school students had insufficient knowledge about breast self-examination and a low percentage of students reported that they had performed breast self examination monthly. The most common reason for not doing breast self- examination was "not knowing how to perform breast self-examination" (98.5%. Most of the students had little knowledge of the risk factors for breast cancer. The most widely known risk factor by the students was personal history of breast cancer (68.7%. There was a significant relation between breast self-examination practice and age, school grade, knowledge about breast cancer and knowledge about breast self- examination. Conclusion There is a need to increase knowledge of adolescent females about the risks of breast cancer and benefits of early detection. In fact, health care professionals can develop effective breast health care programs and help young women to acquire good health habits.

  10. Response to Letter to Editor: Advancement flaps are enough in most cases as onco plastic technique for breast cancer even with central or periareolar localization

    International Nuclear Information System (INIS)

    (1)Thirteen cases with N0 have been operated by a complete axillary dissection. Would it be better to undertake sentinel lymph node biopsy (SLNB) in these cases? Answer: Our treatment guidelines do not include SLNB, although it is very much acceptable, but our breast cancer patients are not candidates for such technique. However, previous studies at NCI found an incidence of LN metastasis in T1 tumors of about 70%. (2) The patients with periareolar tumor localization (half of the patients) underwent needlessly a pedicled flap operation instead of an advancement flap or simple rotation flap. They are simple and therefore less time-consuming oncoplastic procedures. They do not require whole mpple areola complex. Therefore, advancement flaps or periareolar mastopexy (1) was more reasonable. Answer: We believe that the proposed technique (advancement flaps) will result in nipple areola complex shift and bad cosmetic outcome, that is why our described technique, although the number of cases is limited, will allow for centralization of the NAC and better cosmcsis. (3) Ten patients with N2 represent locally advanced cancer of breast (Stage III). They should be treated primarily by systemic therapy instead of surgery first. It needs explanation. Answer: Now, in our treatment protocols, patients with advanced disease, or nodal disease would receive CT primarily N2 regarding the number of lymph nodes. (4) Four cases with N+ have not been given adjuvant chemotherapy. It should be explained. Answer: They refused to receive CT. (5) The rates of good cosmetic results were the same for both patients and doctors. But in the literature, the rates of health professionals are nearly always lower than patients (2) . It needs explanation. Answer: We do not think it needs explanation. This is a subjective way for analysis of cosmetic appearance. Moreover, according to the literature, patient expectations usually lead to a lower acceptance than surgeons. (6) The condition of

  11. Recent advances in technologies for the detection of occult metastatic cells in bone marrow of breast cancer patients

    International Nuclear Information System (INIS)

    Approximately half of breast cancer patients with stage I–III disease will suffer metastatic disease despite resection with tumour-free margins. In 30–40% of these patients, individual carcinoma cells can already be detected at the time of primary therapy in cytological bone marrow preparations using immunocytochemistry. Numerous prospective clinical studies have shown that the presence of occult metastatic cells in bone marrow is prognostically relevant to patient survival. Only a few studies failed to do so, thus stimulating a critical discussion on the methodology and clinical value of bone marrow analysis. The potential for obtaining improved prognostic information on patient outcome, for monitoring tumour cell eradication during adjuvant and palliative systemic therapy, and for specifically targeting tumour biological therapies are intriguing clinical opportunities that may be afforded by bone marrow analysis. Standardized and robust methodology is a prerequisite for clinical application of these techniques, however

    Case Study Amy is a 44-year-old woman with severe autism. She lives with her sister Susan, who is her caregiver and guardian. Amy is ambulatory and able to dress and feed herself. She is a healthy individual with no other significant comorbidities. She walks daily and enjoys her sister's company. Amy's life expectancy is greater than 10 years. However, she is difficult to care for medically, as she will not allow a physical examination and strikes out when strangers try to touch her. She is nonverbal and unable to participate in decision-making. INITIAL DIAGNOSIS Amy has a history of breast cancer diagnosed 2 years ago, originally presenting as a stage I lesion (T2N0) that was palpated by her caregiver while bathing. She underwent right simple mastectomy with sentinel lymph node resection. Susan recalls that the mastectomy was a very challenging ordeal, as Amy kept pulling out IV lines, drains, and dressings. Susan felt that Amy withdrew from her after the procedure as she most likely associated Susan with the cause of the pain, making her role as caregiver more difficult. Pathology confirmed an invasive ductal carcinoma, moderately differentiated, 2.4 cm, estrogen/progesterone receptor negative, HER2/neu negative, with negative surgical margins. Two right axillary sentinel lymph nodes were negative for disease. The standard of care for a patient with these tumor features is surgery plus adjuvant chemotherapy (National Comprehensive Cancer Network [NCCN], 2012). According to the Adjuvant Online! database (2012), Amy's risk for relapse was approximately 40% without adjuvant treatment; her risk for mortality was approximately 29%. After meeting with a medical oncologist, Amy did not receive adjuvant chemotherapy. According to Susan, she was not offered the choice, and the decision was not explained to them. She was simply told that it was not necessary. Aside from pathology, previous records were unavailable for review. Medical assessment of Amy's level of autism

Place and Duration of Study: This study was carried out at People's Medical College Hospital (PMCH) Nawabshah from June 1995 to May, 2000 for a period of five years. Subjects and Methods: Fifty patients having carcinoma breast and admitted to surgical department ware included in study. Results: Eighty four percent of these patients presented in advanced stage of the disease. Well established predisposing factors like early menarche, age at first pregnancy, breast feeding and number of children did not contribute to the risk of developing breast cancer in our patients. Conclusion: Majority of breast cancer patients present in advance stage of the disease, hence can not be benefited from modern methods of treatment. The reasons for this delayed presentation are multi fold and are discussed here. (author)

Seven women with BrE-3 antigen-positive, metastatic breast carcinoma underwent (111)In huBrE-3 infusion (5 mCi; 50 mg), followed by serial gamma camera imaging and plasma sampling. Region of interest analysis of images was used to make radiation absorbed dose estimates for (111)In huBrE-3. Data were extrapolated to 90Y huBrE-3. Human anti-human antibody (HAHA) response was measured in serum samples obtained up to 3 months after infusion. Patients tolerated infusions well. Seventy-six percent of 105 known sites of disease were identified on planar and single-photon emission computed tomography scans. For six of seven patients, a biexponential model fit the plasma time-activity curve best with an average T1/2alpha=10.6+/-8.5 (SD) h and average T1/2beta=114.2+/-39.2 h. Radiation absorbed dose estimates for (111)In huBrE-3 for whole body averaged 0.53+/-.08 rads/mCi. Dose estimates for 90Y huBrE-3 for marrow averaged 8.4+/-11.9 rads/mCi, and for tumors, 70+/-31.5 rads/mCi. Liver radioactivity uptake averaged 19.7+/-8.8% injected dose at 24 h after infusion, translating into an average radiation absorbed dose 21.1+/-12 rads/90Y mCi administered. Only one of seven patients demonstrated a low level of HAHA response. Although the plasma half-lives are longer and marrow dose higher for radiolabeled huBrE-3 compared with the murine construct, the excellent tumor localization, good tumor dosimetry, and low immunogenicity support the use of 90Y-huBrE-3 antibody for radioimmunotherapy of breast cancer.

    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.

    The prognostic value of tumor infiltrating lymphocytes in breast cancer has long been recognized by histopathologists. These observations were reaffirmed by recent immunohistochemistry and gene expression profiling studies that also revealed an association between greater chemotherapy sensitivity and extensive lymphocytic infiltration in early stage breast cancers treated with neoadjuvant chemotherapy. These results suggest that local anti-tumor immune response can at least partially control cancer growth and may mediate the antitumor effects of chemotherapy. However, until recently, there was no direct clinical evidence to demonstrate that enhancing anti-tumor immune response could lead to clinical benefit in breast cancer patients. The recent development of clinically effective immune checkpoint inhibitors made it possible to test the therapeutic impact of augmenting the local anti-tumor immune response. Two Phase I clinical trials using single agent anti-PD-1 (MK-3475, pembrolizumab) and anti-PD-L1 (MPDL3280A, atezolizumab) antibodies demonstrated close to 20% tumor response rates in heavily pretreated, metastatic, triple negative breast cancers. The most remarkable feature of the responses was their long duration. Several patients had disease control close to a year, or longer, which has not previously been seen with chemotherapy regimens in this patient population. A large number of clinical trials are currently underway with these and similar drugs in the neoadjuvant, adjuvant and metastatic settings to define the role of this new treatment modality in breast cancer.

    Background. For patients with locally advanced breast cancer (LABC) undergoing neoadjuvant chemotherapy (NACT), the European Guidelines for Breast Imaging recommends magnetic resonance imaging (MRI) to be performed before start of NACT, when half of the NACT has been administered and prior to surgery. This is the first study addressing the value of flow-insensitive apparent diffusion coefficients (ADCs) obtained from diffusion-weighted (DW) MRI at the recommended time points for pretreatment prediction and monitoring of treatment response. Materials and methods. Twenty-five LABC patients were included in this prospective study. DW MRI was performed using single-shot spin-echo echo-planar imaging with b-values of 100, 250 and 800 s/mm2 prior to NACT, after four cycles of NACT and at the conclusion of therapy using a 1.5 T MR scanner. ADC in the breast tumor was calculated from each assessment. The strength of correlation between pretreatment ADC, ADC changes and tumor volume changes were examined using Spearman's rho correlation test. Results. Mean pretreatment ADC was 1.11 +- 0.21 x 10-3 mm2/s. After 4 cycles of NACT, ADC was significantly increased (1.39 +- 0.36 x 10-3 mm2/s; p=0.018). There was no correlation between individual pretreatment breast tumor ADC and MR response measured after four cycles of NACT (p=0.816) or prior to surgery (p=0.620). Conclusion. Pretreatment tumor ADC does not predict treatment response for patients with LABC undergoing NACT. Furthermore, ADC increase observed mid-way in the course of NACT does not correlate with tumor volume changes.

    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.

    Objective Considering the increasing number of treatment options for metastatic breast cancer (MBC), it is important to develop high-quality methods to assess the cost-effectiveness of new anti-cancer drugs. This study aims to develop a global economic model that could be used as a benchmark for the economic evaluation of new therapies for MBC. Methods The Global Pharmacoeconomics of Metastatic Breast Cancer (GPMBC) model is a Markov model that was constructed to estimate the incremental cost per quality-adjusted life years (QALY) of new treatments for MBC from a Canadian healthcare system perspective over a lifetime horizon. Specific parameters included in the model are cost of drug treatment, survival outcomes, and incidence of treatment-related adverse events (AEs). Global parameters are patient characteristics, health states utilities, disutilities, and costs associated with treatment-related AEs, as well as costs associated with drug administration, medical follow-up, and end-of-life care. The GPMBC model was tested and validated in a specific context, by assessing the cost-effectiveness of lapatinib plus letrozole compared with other widely used first-line therapies for post-menopausal women with hormone receptor-positive (HR+) and epidermal growth factor receptor 2-positive (HER2+) MBC. Results When tested, the GPMBC model led to incremental cost-utility ratios of CA$131 811 per QALY, CA$56 211 per QALY, and CA$102 477 per QALY for the comparison of lapatinib plus letrozole vs letrozole alone, trastuzumab plus anastrozole, and anastrozole alone, respectively. Results of the model testing were quite similar to those obtained by Delea et al., who also assessed the cost-effectiveness of lapatinib in combination with letrozole in HR+/HER2 + MBC in Canada, thus suggesting that the GPMBC model can replicate results of well-conducted economic evaluations. Conclusions The GPMBC model can be very valuable as it allows a quick and valid assessment of the cost

    Primary chemotherapy is a useful strategy for the treatment of locally advanced breast cancer and therefore allows in vivo evaluation of the action of cytotoxic drugs and the possibility of accomplishing conservative breast surgeries, as well as the early treatment of metastasis. Mechanisms of resistance to the drugs include the action of protein associated with the efflux of drugs from the intracellular environment hindering their activity; one of the most studied proteins is P-glycoprotein codified by the MDR-1 gene. The presence of polymorphisms can determine different physiological actions of these proteins, intervening with the response of the drug's action. We evaluated the presence of single nucleotide polymorphism (SNP) C3435T of the MDR-1 gene and its correlation with the response to primary chemotherapy using the RECIST criteria. Forty-one Brazilian women with stages II and III breast cancer using the PCR-RFLP analysis were evaluated. Thirty-three patients with the SNP genotype (TT and CT) and eight patients with the wild genotype (CC) were found; there was no statistically significant correlation between the diverse genotypes and the clinical and pathological responses according to the Cramer correlation coefficient (V = 0.14). The parameters: nuclear and histological degree, and estrogens, progesterone and c-erb B2 receptors did not demonstrate a statistical correlation with the SNP C3435T. Patients with complete pathological response (12.5%) showed only the polymorphic genotype and not the wild genotype. The characteristics of miscegenation in our population could explain the absence of the characterization of a sub-group of individuals where the presence of the polymorphic genotype influenced the response to the primary chemotherapy.

  19. Gene aberrations of RRM1 and RRM2B and outcome of advanced breast cancer after treatment with docetaxel with or without gemcitabine

    International Nuclear Information System (INIS)

    The purpose of the present study was to retrospectively evaluate whether copy number changes of the genes encoding the ribonucleotide reductase subunit M1 (RRM1) and/or subunit M2B (RRM2B) predict sensitivity to gemcitabine administered in combination with docetaxel compared to single agent docetaxel in advanced breast cancer patients. Primary tumor samples from patients randomly assigned to gemcitabine plus docetaxel or docetaxel alone were analyzed for RRM1 and RRM2B copy number changes using Fluorescence In Situ Hybridization (FISH) technology with probes covering respectively RRM1 at 11p15.5 and a reference probe covering the centromere of chromosome 11 (CEN-11), and RRM2B at 8q22.3 and a reference probe covering the centromere of chromosome 8 (CEN-8). The assays were validated in a material of 60 normal breast samples. Time to progression (TTP) was the primary endpoint. Overall survival (OS) and response rate (RR) were secondary endpoints. Associations between RRM1/CEN-11 and/or RRM2B/CEN-8 ratios and time-to-event endpoints were analyzed by unadjusted and adjusted Cox proportional hazards regression models. Heterogeneity of treatment effects on TTP and OS according to gene status were investigated by subgroup analyses, and the Wald test was applied. All statistical tests were two-sided. FISH analysis for both RRM1 and RRM2B was successful in 251 patients. RRM1 and RRM2B aberrations (deletions and amplifications) were observed in 15.9% and 13.6% of patients, respectively. RRM1 aberrations were associated with a decreased OS in the time interval 1.5-7.4 years (hazard ratio = 1.72, 95% confidence interval = 1.05-2.79, P = 0.03). RRM2B aberrations alone or in combination with RRM1 aberrations had no prognostic impact in terms of TTP or OS. RR was not different by gene status. No significant differences were detected in TTP or OS within subgroups according to gene status and chemotherapy regimen. This study demonstrated the presence of RRM1 and RRM2B copy number

  3. Combining chemotherapy with radiation in breast cancer

    International Nuclear Information System (INIS)

    Breast cancer is one of the most important global health problems. Over the last years introduction of mammography screening and increased efficacy of adjuvant therapies resulted in the reduction of mortality in this malignancy. A proportion of patients with breast cancer has indications for adjuvant radiotherapy and chemotherapy, however optimal schedules of combining these two modalities remain controversial. In clinical practice typically chemotherapy and radiotherapy are used sequentially, but this strategy is not supported by the results of large clinical trials. There is theoretical rationale for the concomitant use of both modalities, but increased cardiotoxicity and skin reactions of anthracycline-based regimens do not allow for this strategy. Further investigations are essential to determine the safety of taxane-based schedules combined with radiotherapy, particularly with regard to pneumotoxicity. Concurrent chemo-radiotherapy with the use of selected schemes may be considered in patients with locally advanced cancer, but this strategy still should be verified in large randomized studies.

    In recent years there have been major advances in the treatment of breast cancer. However, taking the prescribed medication for a sufficient period of time is crucial to the success of any therapy. Thus far, no database-based studies have been published in German-speaking countries empirically examining the influence of the physician on the compliance of patients. The aim of this study is to investigate, quantify, and critically discuss the effect treating physicians have on the compliance of their breast cancer patients. Patients with a confirmed breast cancer diagnosis who started therapy (tamoxifen or aromatase inhibitors) between January 2001 and December 2011 were selected from the representative IMS Disease Analyzer database and analyzed with regard to their compliance. Practices were grouped into two categories concerning the compliance of all treated patients. A regression model showed that a breast cancer patient who is treated in a practice with a trend toward poor compliance has a nearly 60% higher risk for treatment discontinuation than would be the case in a practice with good compliance. It shows how important it is to motivate physicians to strive toward good compliance rates. PMID:24454275

    Full Text Available Purpose : Staging of breast tumor has important implications for treatment and prognosis. This study aims at pinpointing the frequency of each stage among familial and nonfamilial breast cancers. Materials and Methods : Ninety-nine Jordanian females diagnosed with familial and nonfamilial breast cancer between 2000 and 2002 were enrolled in this study All breast cancer cases were staged according to the TNM classification into in situ, early invasive, advanced invasive and metastatic. Results : Forty-three cases were familial breast cancer and 56 were nonfamilial. One female breast cancer was diagnosed with ductal carcinoma in situ (DCIS cancer. Fifty cases were diagnosed in early stages of invasive breast cancer, of which 31 cases were familial, 29 cases were classified as advanced invasive, where 21 cases were nonfamilial and 19 cases were metastatic stage of breast cancer, with 16 nonfamilial cases. Stage 2b was the most common stage of early invasive cases and represented 48% of the early stage of breast cancer. On the other hand, among cases diagnosed with advanced invasive breast cancer, stage 3a was the most common stage and represented 89.6% of the advanced stage. Interestingly, all cases of stage 3a belonged to TNM stages of T2N2M0 and T3N1M0. The tumor size in all cases of Jordanian females diagnosed with advanced invasive breast cancer exceeded 2 cm in size due to selection bias from symptomatic women in our study. Conclusion : The incidence of nonfamilial breast cancer was slightly higher than that of the familial type amongst studied the Jordanian females studied. The early invasive stage of breast cancer was more common in the familial while the advanced invasive and metastatic breast cancer cases were encountered more often in the nonfamilial type. Our study was based on a small sample and symptomatic women. Therefore, more research with larger population samples is needed to confirm this conclusion.

    Wilcoxon analysis and the Cox-analysis were performed to evaluate time to progression (TTP) in relation to marker expression. RESULTS: Aromatase expression was associated with ER, but not with PR or COX-2 expression in carcinoma cells. Measurements of aromatase in WS were not comparable to results from...... TMAs. Expression of COX-2 and aromatase did not predict response to endocrine therapy. Aromatase in combination with high PR expression may select letrozole treated patients with a longer TTP. CONCLUSION: TMAs are not suitable for IHC analysis of in situ aromatase expression and we did not find COX-2...... estrogen synthesis may not be the major source of intratumoral estrogen. However, aromatase expression in combination with high PR expression may select letrozole treated patients with longer TTP. TRIAL REGISTRATION: Sub-study of trial P025 for advanced breast cancer....

  15. Dermatologic radiotherapy and breast cancer

    International Nuclear Information System (INIS)

    This study was set up to provide quantitative data to evaluate unsubstantiated claims that improper dermatologic radiation techniques may cause breast cancer. A thin mylar window ionization rate meter placed at the location of the right breast of an Alderson-RANDO anthropomorphic phantom was used to measure direct and scatter radiation reaching the female breast during radiotherapy of the facial region (as given for acne). The results indicate that scatter doses are very small; they are influenced by radiation quality and the use or nonuse of a treatment cone. Quantitative risk estimates show that the very small risk of breast cancer induction can be reduced even further by the use of proper radiation protection measures. (orig.)

    Breast cancer is the leading type of malignancy and the leading cause of cancer-related deaths in women worldwide. The screening programs and advances in the treatment of patients with breast cancer have led to an increase in overall survival. Cancer registry systems play an important role in providing basic data for research and the monitoring of the cancer status. In this study, the results of the 10-year national cancer registry (NCR) of Iran in breast cancer are reviewed. NCR database records were searched for primary breast cancer records according to ICD-O-3 coding and the cases were reviewed. A total of 52,068 cases were found with the coding of primary breast cancer. Females constituted 97.1% of the cases. Breast cancer was the leading type of cancer in Iranian females, accounting for 24.6% of all cancers. The mean age of the women with breast cancer was 49.6 years (95%CI 49.5-49.6). Most of the cases (95.7%) were registered as having invasive pathologies (behavior code 3). The most common morphology of primary breast cancer was invasive ductal carcinoma (ICD-O 8500/3) followed by invasive lobular carcinoma (ICD-O 8520/3) with relative frequencies of 77.8% and 5.2%, respectively. The average annual crude incidence of primary breast cancer in females was 22.6 (95%CI 22.1-23.1) per 100,000 females, with an age-standardized rate (ASR) of 27.4 (95%CI 22.5-35.9). There were no data on survival, staging or immunohistochemical marker(s) of the breast-cancer-registered cases. The incidence of breast cancer in Iran is lower than in low-middle-income neighboring countries. The NCR data registry of breast cancer is not accurate in monitoring the effect of screening programs or determining the current status of breast cancer in Iran. Screening programs of breast cancer in Iran have failed to enhance the detection of the patients with in situ lesion detection. A quality breast cancer registry and a screening program for breast cancer are both needed. PMID:26070507

    Objective: Taking tamoxifen orally is the main endocrine therapy of the premenopausal breast cancer with positive hormone receptor, but numerous patients developed to be advanced refractory breast cancer because of drug resistance.Our study investigated a role of the combination of bilateral oophorectomy and exemestane in the management of advanced refractory breast cancer. Methods: The bilateral oophorectomy was carried out in 17 patients. One week after the operation,exemestane was taken orally (25 mg/d). The median time to progression (TTP), the median survival time and the survival rate were calculated using Kaplan-Meier methods. Results: Seventeen patients age ranged from 26 to 44 years (median, 36 years) were treated with an overall response rate of 64.70%, TTP was 8 months and the median survival time was 31 months.The survival rate of 1-year, 3 years and 5 years was 88.24%, 64.71%, 29.41%, respectively. There have no grade Ⅲ/Ⅳ side effects appeared. Conclusion: Bilateral oophorectomy combined with exemestane is safe and effective for advanced refractory premenopausal breast cancer with positive hormone receptor and it is well-tolerated.

    Full Text Available Background: Primary synchronous bilateral breast cancer (PSBBC is a rare clinical entity. The reported incidence ranges between 0.3% and 12%. There are several controversial issues regarding PSBBC pertaining to the diagnostic criteria, nomenclature, and management policies. Materials and Methods: Fourteen cases of PSBBC treated between 2001 to 2010 at our institute were retrospectively analysed in regards to demographic data, management and follow up. Results: PSBBC constituted 0.19% of total breast cancer patients at our institute. Age ranged from 28 to 78 years. PSBBC were detected by clinical examination in eight cases and by mammography in six cases. Twelve patients underwent bilateral modified radical mastectomy, one had unilateral mastectomy on one side and breast conservation on the other side and one patient has bilateral breast conservation. Majority of patients belonged to stage 2 and stage 3. All patients were found to have invasive ductal carcinoma. Five cases were ER/PR positive and 8 patients were triple hormone receptor negative. Eight patients received unilateral and six received bilateral adjuvant radiotherapy. Nine patients received adjuvant chemotherapy. 5 patients received adjuvant hormonal therapy. Median follow up of patients was 15.4 months. Conclusion: PSBBC is a rare event warranting awareness and screening of the contralateral breast in patients with unilateral breast cancer. These patients require individualized treatment planning based on the tumor factors of the index lesion. Further multi institutional prospective studies are needed for adequate understanding of management of PSBBC.

    Full Text Available Male breast cancer is an uncommon disease accounting for only 1% of all breast cancers. We present the evaluation, treatment and outcome of male patients seen with breast cancer in our institution. Male patients that had histological diagnosis of breast cancer from 2001 to 2010 were retrospectively evaluated. After evaluation patients were treated with modified radical mastectomy. Combination chemotherapy was given to patients with positive axillary lymph nodes. Radiotherapy and hormonal therapy were also employed. There were 57 male patients with breast cancer which accounted for 9% of all breast cancers seen during the study period. Their mean age was 59 ± 2.3 years. The mean tumor diameter was 13 ± 2.5 cm. Fifty three (93% patients presented with advanced disease including 15 with distant metastasis. Four patients with stage II disease were treated with modified radical mastectomy, chemotherapy and tamoxifen. Of the 30 patients with sage III disease that had modified radical mastectomy, complete axillary clearance and tumor free margins were achieved in 25. Overall 21 (36.8% patients were tumor free at one year. Overall 5-year survival was 22.8%. In conclusion, male patients with breast cancer present with advanced disease which is associated with poor outcome of treatment.

    Metastatic breast cancer is a disease of early breast cancer that usually occurs several years after the early breast cancer. Breast cancer is the most common cancer among Iranian women. According to the new statistics in Iran 6 160 breast cancers are diagnosed in the country each year and 1 063 cases lead to death. In this paper, epidemiology, diagnosis and treatment have been investigated. In this study, case-control clinical trials and open studies with adequate data were collected. Due to the higher risk of age group 40-49 years and the advent of advanced breast cancer in Iranian women, the early diagnosis and determination of the exact size of the tumor before surgery is important in choosing a therapy plan. The decision on the therapy of invasive breast cancer depends on several factors such as cancer stage, tumor size and type, pathological and cytological status of the tumor, the patient’s opinion, the presence or absence of estrogen and progesterone receptors in the cytoplasm of tumor cells and so on.

    Breast cancer is the most frequent cancer of women in western countries. There are one million new cases per year in the world which represents 22% of all female cancers, and more than 370.000 deaths due to breast cancer per year (14% of cancer mortality). More than half of breast cancers are associated with axillary nodal involvement. Post-operative radiation therapy (XRT) is a crucial part of locoregional treatment in axillary nodal involvement breast cancer owing to a 15-years risk reduction of locoregional recurrence of 70% and to a 5.4% risk reduction of specific mortality. In 3D-conformal irradiation in such breast cancers, target volumes are chest wall when mastectomy was performed or breast and boost of tumor bed in case of breast conservative surgery, and supra-clavicular and/or axillary and/or internal mammary node areas. The main organs at risk are ipsilateral lung, heart and brachial plexus. The aim of this article is to describe epidemiologic, radio anatomic and prognostic features of axillary nodal involvement breast cancer and to propose guidelines for 3D-conformal treatment planning in locally advanced breast cancers. This review is illustrated by a case report. (authors)

    International Nuclear Information System (INIS)

    Neoadjuvant chemotherapy (NACT) is an essential part of multi-disciplinary management of locally advanced breast cancer (LABC). In this study, we aimed at evaluating the role of 99mTc-Sestamibi scinti-mammography in assessing response to NACT in patients with LABC. A total of 42 patients of histologically proven LABC were enrolled in this prospective study. Imaging was performed according to pre-defined protocol at 10 min and 4 h after injection of tracer before the start of chemotherapy, 48 h after start of chemotherapy and at the end of chemotherapy. Quantitative parameters were obtained by calculating the ratio of activity in a region of interest (ROI) drawn over the tumor and the same sized ROI drawn in corresponding location in contra lateral breast. Early response assessment in patients with LABC to NACT with 99mTc-Sestamibi scintimammography is feasible and if confirmed by further studies can find routine clinical application in differentiating responders from non-responders.

    International Nuclear Information System (INIS)

    declared disease free 30 months later. The third case was a 32-year-old Saudi female who has been lactating for 5 months presented with a month history of a right breast lump. There was no history of nipple discharge or past history of any benign breast diseases. There was no family history of breast carcinoma. Clinically, there was an irregular right breast mass (5x3 cm) in the upper inner quadrant with palpable right axillary lymph nodes. She underwent right simple mastectomy and axillary clearance. Histology showed grade II infiltrating ductal carcinoma with 15/18 lymph nodes were positive. Postoperative adjuvant therapy was given but was lost to follow up 6 months after surgery. Chest wall radiation for cancers detected in the second or third trimester is delayed until after delivery to avoid fetal growth retardation and still births.3,4 The risk of abortion and fetal malformations is highest during embryogenesis in the first trimester and varies with the choice of chemotherapeutic agents. Recent evidence suggests that the risk of fetal malformations associated with administration of chemotherapeutic agents after the first trimester is not greater than the background control.6 The decision on postoperative adjuvant chemoradiation therapy in all the cases was made easy by the fact that CS was performed at the time of mastectomy in case one who gave birth to a healthy baby and that cases 2 and 3 were postpartum and were only lactating. Termination of pregnancy is considered in females presenting early in pregnancy with advanced or metastatic cancer necessitating chemotherapy and radiation

  1. Locally advanced non inflammatory breast cancer treated by combined chemotherapy and preoperative irradiation: updated results in a series of 120 patients

    International Nuclear Information System (INIS)

    Purpose. - To evaluate our updated data concerning survival and locoregional control in a study of locally advanced non inflammatory breast cancer after primary chemotherapy followed by external preoperative irradiation. Patients and methods. - Between 1982 and 1998, 120 patients (75 stage IIIA, 41 stage IIIB, and 4 stage IIIC according to AJCC staging system 2002) were consecutively treated by four courses of induction chemotherapy with anthracycline-containing combinations followed by preoperative irradiation (45 Gy to the breast and nodal areas) and a fifth course of chemotherapy. Three different locoregional approaches were proposed, depending on tumour characteristics and tumour response. After completion of local therapy, all patients received a sixth course of chemotherapy and a maintenance adjuvant chemotherapy regimen without anthracycline. The median follow-up from the beginning of treatment was 140 months. Results. - Mastectomy and axillary dissection were performed in 49 patients (with residual tumour larger than 3 cm in diameter or located behind the nipple or with bifocal tumour), and conservative treatment in 71 patients (39 achieved clinical complete response or partial response >90% and received additional radiation boost to initial tumour bed; 32 had residual mass ≤3 cm in diameter and were treated by wide excision and axillary dissection followed by a boost to the excision site). Ten-year actuarial local failure rate was 13% after irradiation alone, 23% after wide excision and irradiation, and 4% after mastectomy (p =0.1). After multivariate analysis, possibility of breast-conserving therapy was related to initial tumour size (<6 vs. ≥6 cm in diameter, p =0.002). Ten-year overall metastatic disease-free survival rate was 61%. After multivariate analysis, metastatic disease-free survival rates were significantly influenced by clinical stage (stage IIIA-B vs. IIIC, p =0.0003), N-stage (N0 vs. N1-2a, and 3c, p = 0.017), initial tumour size (<6

    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

    Gradually, FDG-PET/CT has been strengthening within the diagnostic algorithms of oncological diseases. In many of these, PET/CT has shown to be useful at different stages of the disease: diagnosis, staging or re-staging, treatment response assessment, and recurrence. Some of the advantages of this imaging modality versus CT, MRI, bone scan, mammography, or ultrasound, are based on its great diagnostic capacity since, according to the radiopharmaceutical used, it reflects metabolic changes that often occur before morphological changes and therefore allows us to stage at diagnosis. Moreover, another advantage of this technique is that it allows us to evaluate the whole body so it can be very useful for the detection of distant disease. With regard to breast cancer, FDG-PET/CT has proven to be important when recurrence is suspected or in the evaluation of treatment response. The technological advancement of PET equipment through the development of new detectors and equipment designed specifically for breast imaging, and the development of more specific radiopharmaceuticals for the study of the different biological processes of breast cancer, will allow progress not only in making the diagnosis of the disease at an early stage but also in enabling personalized therapy for patients with breast cancer.

Some of the advantages of this imaging modality versus CT, MRI, bone scan, mammography, or ultrasound, are based on its great diagnostic capacity since, according to the radiopharmaceutical used, it reflects metabolic changes that often occur before morphological changes and therefore allows us to stage at diagnosis. Moreover, another advantage of this technique is that it allows us to evaluate the whole body so it can be very useful for the detection of distant disease. With regard to breast cancer, FDG-PET/CT has proven to be important when recurrence is suspected or in the evaluation of treatment response. The technological advancement of PET equipment through the development of new detectors and equipment designed specifically for breast imaging, and the development of more specific radiopharmaceuticals for the study of the different biological processes of breast cancer, will allow progress not only in making the diagnosis of the disease at an early stage but also in enabling personalized therapy for patients with breast cancer.

  5. Breast cancer epidemiology and risk factors

    International Nuclear Information System (INIS)

    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

    Expression of proliferating cell nuclear antigen (PCNA) has been shown to be of prognostic value in patients with certain types of cancer. The aim of this study was to determine if the abundance of PCNA is inversely correlated with survival of patients with breast cancer. Paraffin blocks were available from 68 patients, all of whom had been followed clinically for at least 5 years. Sections from 20 patients showed no reactivity to PCNA and were excluded from the study because it was not possible to distinguish between true negatives and false negatives (those due to poor fixation of the original specimens). The PCNA index (the number of stained cancer cells as a percentage of the total number of cancer cells present) was calculated for the remaining 48 patients. Results were analysed by Wilcoxon's rank sum test (two tailed) and Pearson's correlation coefficient. There was no statistical difference between the PCNA indices of those patients dead from their disease within 5 years of diagnosis compared with those alive and without signs of breast cancer at 5 years. There was also no correlation between PCNA index and size of the cancer, involvement of axillary lymph nodes, time to recurrence or time to death. There was, however, a significant correlation between PCNA index and histological grade (P = 0.029). It appears that PCNA staining of stored paraffin sections is of little prognostic value in patients with breast cancer. PMID:8101708

  17. Breast cancer seeking agents: Basic approach

    International Nuclear Information System (INIS)

    The knowledge of biochemical and physiological mechanisms involved in tissue localization is important so as to understand the information given by diagnostic nuclear medicine imaging, and eventually to design new radiopharmaceuticals. The cellular mechanisms which permit a high cancer uptake involve the perfusion and metabolism within the tumour. All these phenomena can contribute to a high concentration of particular radiotracers in cancer and can create a favourable tumour/background ratio uptake sufficient for cancer imaging. Those molecules might be also powerful tools for reaching and advanced understanding of neoplastic and even ''normal'' cell biology. During these last years, some radiotracer specifically designed for different applications proved to be promising radiopharmaceuticals for breast cancer imaging. This is the case of monoclonal antibodies (Mabs) developed in the past against membrane cancer antigens. Other tracers, originally proposed for the study of vascular perfusion have also revealed a capacity to be taken up by cancer cells. The radiopharmaceuticals mostly used as tumour seeking agents today (Radiothallium, Sestamibi, Tetrophosmin) were generated with other applications in mind. In this paper whey review the mechanisms of uptake of the most relevant agents currently proposed for breast cancer imaging, including 18F-fluorodeoxyglucose (FDG). The radiotracers will be examined on the basis of the available scientific evidence regarding their cellular uptake and release. Moreover, they report their preliminary studies on the cellular uptake and release of these and other compounds recently introduced in clinical trials

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%.

    2016-08-01

    BARD1 (BRCA1 associated RING domain protein 1), as an important animal tumor suppressor gene associated with many kinds of cancers, has been intensively studied for decades. Surprisingly, homolog of BARD1 was found in plants and it was renamed AtROW1 (repressor of Wuschel-1) according to its extremely important function with regard to plant stem cell homeostasis. Although great advances have been made in human BARD1, the function of this animal tumor-suppressor like gene in plant is not well studied and need to be further elucidated. Here, we review and summarize past and present work regarding this protein. Apart from its previously proposed role in DNA repair, recently it is found essential for shoot and root stem cell development and differentiation in plants. The study of AtROW1 in plant may provide an ideal model for further elucidating the functional mechanism of BARD1 in mammals. PMID:27502904

  8. The role of 18F-FDG PET/CT in evaluation of early response to neoadjuvant chemotherapy in patients with locally advanced breast cancer

    International Nuclear Information System (INIS)

    We evaluated the role of 18F-FDG PET/CT for the assessment of response after two cycles of neo-adjuvant chemotherapy (NACT) for breast cancer. Twenty-three women with locally advanced breast cancer were included in this study. Early response to NACT was evaluated after two cycles using clinical examination, CT, and 18F-FDG PET/CT. Final histopathology following surgery after six cycles of NACT served as reference. Baseline PET/CT demonstrated a total of 26 lesions in 23 patients. The size of the primary tumor ranged from 1.90 cm to 11.60 cm, and the maximum value of the standardized uptake value of FDG (SUVmax) ranged from 3.6 to 38.6 (mean, 11.7). Post-chemotherapy PET/CT examinations were done after two cycles of NACT. The size of the primary tumor on follow-up PET/CT examinations ranged from 0.0 cm to 7.6 cm, and SUVmax ranged from 0.0 to 12.0 (mean, 3.96). On clinical, CT, and PET/CT examinations, 50% reduction in the parameters was taken as the cutoff value to differentiate between responders and non-responders. Post-NACT PET/CT demonstrated that 16 patients were responders and 7 non-responders. Among 16 responders on PET/CT scan, 14 were true positive and 2 were false positive when compared with histopathology. Among seven non-responder patients, six were true negative, and one was false negative. The sensitivity, specificity, and accuracy of PET/CT in detecting responders were 93%, 75%, and 87%, respectively. In conclusion, 18F-FDG PET/CT can differentiate responders from non-responders with high accuracy after two cycles of NACT in patients with LABC. (orig.)

    Full Text Available Abstract Background Sentinel lymph node biopsy (SLNB is now considered a standard of care in early breast cancers with N0 axillae; however, its role in locally advanced breast cancer (LABC after neo-adjuvant chemotherapy (NACT is still being debated. The present study assessed the feasibility, efficacy and accuracy of sentinel lymph node biopsy (SLNB using "dye alone" (methylene blue method in patients with LABC following NACT. Materials and methods Thirty, biopsy proven cases of LABC that had received three cycles of neo-adjuvant chemotherapy (cyclophosphamide, adriamycin, 5-fluorouracil were subjected to SLNB (using methylene blue dye followed by complete axillary lymph node dissection (levels I-III. The sentinel node(s was/were and the axilla were individually assessed histologically. The SLN accuracy parameters were calculated employing standard definitions. The SLN identification rate in the present study was 100%. The sensitivity of SLNB was 86.6% while the accuracy was 93.3%, which were comparable with other studies done using dual lymphatic mapping method. The SLN was found at level I in all cases and no untoward reaction to methylene blue dye was observed. Conclusions This study confirms that SLNB using methylene blue dye as a sole mapping agent is reasonably safe and almost as accurate as dual agent mapping method. It is likely that in the near future, SLNB may become the standard of care and provide a less morbid alternative to routine axillary lymph node dissection even in patients with LABC that have received NACT.

    2012-02-01

    Full Text Available Background: Clinical experiences have revealed that patients with breast cancer experience various sexual problems following their treatment. Breast cancer negatively impacts the sexual life of the afflicted couples, and as a traumatic event can influence women’s psychosexual functioning and intimate relationship. This review focuses on sexuality after breast cancer and on a growing need for bio-psycho-social guidelines for breast cancer treatment. Methods: This study aims to review the literature on management, psychological outcomes and sexual dysfunction in patients with breast cancer. Results: Although the benefits of the current treatment strategies are well established, many cancer survivors are at risk for developing psycho physiological symptoms including sexual dysfunction. Cancer and treatment-related factors can influence sexual functioning. We review current treatment -related side effects on sexual functioning such as desire, arousal and orgasm in breast cancer patients. Despite the impact of medical treatment on survival of patients with breast cancer, no satisfactory steps have been taken towards improving sexual functioning of these patients. Conclusion: Breast cancer affects many aspects of sexuality, including changes in physical functioning and in the perception of feminity. Sexual dysfunction following breast cancer should be diagnosed and managed as a systematic approach with multidisciplinary inputs. Healthcare professionals should assess the effects of medical and surgical treatment on the sexuality of breast cancer survivors.

    Overexpression of human epidermal growth factor receptor-2 (HER2) in metastatic breast cancer (MBC) is associated with poor prognosis. This single-arm open-label trial (EGF109491; NCT00508274) was designed to confirm the efficacy and safety of lapatinib in combination with capecitabine in 52 heavily pretreated Chinese patients with HER2-positive MBC. The primary endpoint was clinical benefit rate (CBR). Secondary endpoints included progression-free survival (PFS), time to response (TTR), duration of response (DoR), central nervous system (CNS) as first site of relapse, and safety. The results showed that there were 23 patients with partial responses and 7 patients with stable disease, resulting in a CBR of 57.7%. The median PFS was 6.34 months (95% confidence interval, 4.93-9.82 months). The median TTR and DoR were 4.07 months (range, 0.03-14.78 months) and 6.93 months (range, 1.45-9.72 months), respectively. Thirteen (25.0%) patients had new lesions as disease progression. Among them, 2 (3.8%) patients had CNS disease reported as the first relapse. The most common toxicities were palmar-plantar erythrodysesthesia (59.6%), diarrhea (48.1%), rash (48.1%), hyperbilirubinemia (34.6%), and fatigue (30.8%). Exploratory analyses of oncogenic mutations of PIK3CA suggested that of 38 patients providing a tumor sample, baseline PIK3CA mutation status was not associated with CBR (P = 0.639) or PFS (P = 0.989). These data confirm that the lapatinib plus capecitabine combination is an effective and well-tolerated treatment option for Chinese women with heavily pretreated MBC, irrespective of PIK3CA status.

    One hundred and three patients previously treated with chemotherapy including an anthracycline were entered in a VMMC protocol study: vindesine (Eldisine), mitoxantrone (Novantrone) and mitomycin C (Ametycine). Group A consisted of 41 women who received the protocol published by Belpomme: vindesine (2.5 mg/m2 day 1 and 8) and mitoxantrone (12 mg/m2/day) every 4 weeks, and mitomycin C (8 mg/m2) every 8 weeks. Group B consisted of 62 patients who were treated with a modified protocol: vindesine (2.5 mg/m2) and mitoxantrone (12 mg/m2) every 3 weeks on day 1, and mitomycin C (8 mg/m2) every 6 weeks. Tolerance was acceptable with 79% of patients complaining of weakness. There was a 66% incidence of gastro-intestinal toxicity, a 10.7%-incidence of neurotoxicity (reversible dysethesias), and a 5.8% incidence of cardiotoxicity. There was considerable hematotoxicity of grade 2, 3 and 4: neutropenia 16.6%, thrombocytopenia 7.7%, anemia 21.4%. There was a 19.2% overall objective response rate (CR and PR) (95% confidence interval: 12-30) (CR: 3.2%). The median duration of the response was 39 weeks. There was no significant difference in response rates whether or not the patients (19 cases) were undergoing simultaneous hormonal therapy and no difference according to the protocol used. Similarly, neither menopause nor a previous response to anthracyclines had any effect on the response rate. The 19.2% response in this protocol is similar to other breast cancer salvage chemotherapy protocols for patients who have failed to respond to anthracyclines (< 20%). PMID:1392155

    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

    International Nuclear Information System (INIS)

    To explore the relationship between basal 18F-FDG PET/CT information in breast tumours and survival in locally advanced breast cancer (LABC). This prospective, multicentre study included 198 women diagnosed with LABC. All patients underwent 18F-FDG PET/CT prior to treatment. The maximum standardized uptake value (SUVmax) in tumor (T), lymph nodes (N) and the N/T ratio was obtained in all cases. Stage according to PET/CT imaging (metabolic stage) and conventional imaging techniques (clinical stage) was established. During follow-up, patient status was established (disease free status or not). The relationship between all the variables and overall survival (OS) and disease-free survival (DFS) was analysed using the Kaplan-Meier and Cox regression methods. A ROC analysis was performed to obtain a cut-off value of SUVmax that was useful in the prediction of outcome. The mean SUVmax ± SD values in the primary tumour, lymph nodes and the SUVmax N/T index were 7.40 ± 5.57, 4.17 ± 4.74 and 0.73 ± 1.20, respectively. Higher semiquantitative metabolic values were found in more advanced metabolic and clinical stages. During follow-up, 78.4 % of patients were free of disease. Significant relationships were observed between SUVT and SUVN and patient status. With respect to OS and DFS, significant differences were detected for the metabolic stage. Kaplan-Meier analysis revealed that using the cut-off values, a primary-tumour SUVmax ≥ 6.05 or a nodal SUVmax ≥2.25 were significantly correlated with DFS and OS. PET imaging with 18F-FDG offers prognostic information for LABC that can be obtained preoperatively and noninvasively. (orig.)

  2. Expression of LRP and MDR1 in locally advanced breast cancer predicts axillary node invasion at the time of rescue mastectomy after induction chemotherapy

    International Nuclear Information System (INIS)

    Axillary node status after induction chemotherapy for locally advanced breast cancer has been shown on multivariate analysis to be an independent predictor of relapse. However, it has been postulated that responders to induction chemotherapy with a clinically negative axilla could be spared the burden of lymphadenectomy, because most of them will not show histological nodal invasion. P-glycoprotein expression in the rescue mastectomy specimen has finally been identified as a significant predictor of patient survival. We studied the expression of the genes encoding multidrug resistance associated protein (MDR1) and lung cancer associated resistance protein (LRP) in formalin-fixed, paraffin-embedded tumor samples from 52 patients treated for locally advanced breast cancer by means of induction chemotherapy followed by rescue mastectomy. P-glycoprotein expression was assessed by means of immunohistochemistry before treatment in 23 cases, and by means of reverse-transcriptase-mediated polymerase chain reaction (RT-PCR) after treatment in 46 (6 failed). LRP expression was detected by means of immunohistochemistry, with the LRP-56 monoclonal antibody, in 31 cases before treatment. Immunohistochemistry for detecting the expression of c-erb-B2, p53, Ki67, estrogen receptor and progesterone receptor are routinely performed in our laboratory in every case, and the results obtained were included in the study. All patients had received between two and six cycles of standard 5-fluorouracil, doxorubicin and cyclophosphamide (FAC) chemotherapy, with two exceptions [one patient received four cycles of a docetaxel-adriamycin combination, and the other four cycles of standard cyclophosphamide-methotrexate-5-fluorouracil (CMF) polychemotherapy]. Response was assessed in accordance with the Response Evaluation Criteria In Solid Tumors (RECIST). By these, 2 patients achieved a complete clinical response, 37 a partial response, and the remaining 13 showed stable disease. This makes a

  4. Mutation analysis of breast cancer gene BRCA among breast cancer Jordanian females

    International Nuclear Information System (INIS)

    To screen mutations of the tumor suppressor breast cancer susceptibility gene 1 (BRCA1) within 3 exons among Jordanian breast cancer females. A total of 135 Jordanian breast cancer females were genetically analyzed by denaturing gradient electrophoresis (DGGE) for mutation detection in 3 BRCA1 exons (2, 11 and 20) between 2000-2002 in Al-Basheer Hospital, Amman, Jordan. Of the studied patients 50 had a family history of breast cancer, 28 had a family history of cancer other than breast cancer, and 57 had no family history of any cancer. Five germline mutations were detected among breast cancer females with a family history of breast cancers (one in exon 2 and 4 mutations in exon 11). Another germline mutation (within exon 11) was detected among breast cancer females with family history of cancer other than breast cancer, and no mutation was detected among breast cancer females with no family history of any cancer or among normal control females. Screening mutations within exon 2, exon 11 and exon 20 showed that most screened mutations were within BRCA1 exon 11 among breast cancer Jordanian families with a family history of breast cancer.

  5. Primary chemotherapy and preoperative-dose irradiation for patients with stage II larger than 3 CM or locally advanced non inflammatory breast cancer

    International Nuclear Information System (INIS)

    Purpose: The aims of this prospective study were to evaluate the outcome and the possibility of breast conserving treatment for patients with stage II larger than 3 cm or locally advanced non inflammatory breast cancer, after primary chemotherapy followed by external preoperative-dose irradiation. Materials and methods: Between April 1982 and June 1990, 147 consecutive patients with large breast cancer (stage II > 3 cm [n=50], stage IIIA [n=58], stage IIIB [n=35] and stage IV with isolated clinical supraclavicular or sub-clavicular node involvement [n=4] were treated. The median age was 49 years. Mean tumor size was 6 cm (range 1 - 16 cm). Sixty percent (n=88) of the patients were postmenopausal. Histological classification was : 120 infiltrating ductal carcinomas, 21 infiltrating lobular carcinomas, 4 medullary carcinomas and 2 mucosecreting carcinomas. Grade distribution according to Scarff, Bloom and Richardson was : 14 grade 1, 72 grade 2, 30 grade 3 and 31 non classified. Median follow-up was 94 months from the beginning of the treatment. The induction treatment consisted of 4 courses of chemotherapy (doxorubicin, vincristine, cyclophosphamide, 5-fluorouracil) every 4 weeks followed by preoperative irradiation (45 Gy to the breast and nodal areas) using 60Co in 141 patients and 6 MV photons in 6 patients. A fifth course of chemotherapy was given after radiation therapy and three different locoregional approaches were proposed depending on the tumoral response. In 52 patients (35%) with residual tumor larger than 3 cm in diameter or located behind the nipple or with bifocal tumors, mastectomy and axillary dissection were performed. Ninety-five other patients (65%) benefited from conservative treatment : 48 patients (33%) achieved complete remission and received a booster dose of 25 to 30 Gy to the initial tumor bed by external photon beam or by iridium 192 implant ; 47 patients (32%) who had a residual mass less than or equal to 3 cm in diameter were treated by

Pharmacogenomics (PG has the potential to provide personalized therapy based on individual genetic variability in an effort to maximize efficacy and reduce adverse effects. The benefits of PG include improved therapeutic index, improved dose regimen, and selection of optimal types of drug for an individual or set of individuals. Advanced or metastatic breast cancer is typically treated with single or multiple combinations of chemotherapy regimens including anthracyclines, taxanes, antimetabolites, alkylating agents, platinum drugs, vinca alkaloids, and others. In this review, the PG of breast cancer therapeutics, including tamoxifen, which is the most widely used therapeutic for the treatment of hormone-dependent breast cancer, is reviewed. The pharmacological activity of tamoxifen depends on its conversion by cytochrome P450 2D6 (CYP2D6 to its abundant active metabolite, endoxifen. Patients with reduced CYP2D6 activity, as a result of either their genotype or induction by the coadministration of other drugs that inhibit CYP2D6 function, produce little endoxifen and hence derive limited therapeutic benefit from tamoxifen; the same can be said about the different classes of therapeutics in breast cancer. PG studies of breast cancer therapeutics should provide patients with breast cancer with optimal and personalized therapy.Keywords: pharmacogenomics, genetic, pharmacokinetic, pharmacodynamic, personalized medicine, pharmacotherapy, anticancer drugs, efficacy, safety

    To evaluate the mammographic and clinical features of bilateral breast cancer. We retrospectively reviewed clinical records(n=23) and mammograms (n=15) of 23 patients with bilateral breast cancer. Patients' age, location of the tumor and pathologic staging were determined from clinical records. Mammographic features were classified as spiculated mass, nonspiculated mass, mass with microcalcification, microcalcification only, asymmetric density, and normal. Of the 23 cases of bilateral breast cancer, 8(34.8%) were synchronous and 15(65.2%) were metachronous. Age at diagnosis of cancer in the first breast was between 27 and 59(mean 43) years ; there was no statistically significant difference in mean age between patients with synchronous and metachronous cancer. The mean interval between the diagnosis of each lesion of the metachronous pairs was 9.1 years. In 11 of 23 cases(48%), tumors were locaated in the same quadrant, and in the other 12 cases(52%), they were in different quadrant. At mammography, five of 15 metachronous cancers(33%) were similar in appearance and 10 pairs(67%) were different. In 4 of 23 cases(17%), cancer in the first breast was at stage 0 and stage 1, and in 13 of 23(57%), cancer in the second breast was at this same stage. In bilateral breast cancer, the two breasts frequently show different mammographic features. Cancer of the second breast was at an early stage; this suggest that regular examination and mammography are important and can allow early detection of contralateral breast cancer.

  13. Risk of Subclinical Micrometastatic Disease in the Supraclavicular Nodal Bed According to the Anatomic Distribution in Patients With Advanced Breast Cancer

    International Nuclear Information System (INIS)

    Purpose: To determine the anatomic distribution of gross supraclavicular nodes within the supraclavicular fossa using 2-deoxy-2-[F-18] fluoro-d-glucose (FDG) positron emission tomography/computed tomography (PET/CT) scans, and to evaluate likely coverage of specific regions of the supraclavicular fossa using standard radiation fields. Methods and Materials: We identified 33 patients with advanced or metastatic breast cancer who had a PET/CT scan demonstrating hypermetabolic supraclavicular lymph nodes in 2005. The locations of the involved lymph nodes were mapped onto a single CT set of images of the supraclavicular fossa. These lymph nodes were also mapped onto the treatment-planning CT dataset of 4 patients treated in our institution (2 patients with biopsy-proven supraclavicular nodes and 2 patients with clinically negative supraclavicular nodes). Results: We were able to determine the distribution of 52 supraclavicular lymph nodes in 32 patients. Of 32 patients, 28 (87%) had a history of metastatic disease, and 2 patients had isolated nodal recurrences. Five patients had supraclavicular nodes posterior to the vertebral body transverse process, and several lymph nodes were in close proximity to the medial field border, raising the possibility of geographic miss in these areas. Conclusions: In patients with locally advanced disease, increased coverage of the supraclavicular fossa medially and posteriorly may be warranted

  16. Primary breast cancer: European radiotherapy trials

    International Nuclear Information System (INIS)

    For many years in Europe, surgically operable breast carcinomas have been treated by conservative treatments. There are two methods of conservative treatment: limited surgery with or without auxiliary dissection followed by irradiation and irradiation as the primary treatment. Depending on the size of the primary tumor and clinical findings in the axillae, patients were referred to either of the two treatment alternatives. Generally, limited surgery and irradiation was performed in patients with early breast carcinomas, while irradiation as the primary treatment was used for more locally advanced cancers. Since 1960, conservative treatments with megavoltage for patients with invasive breast carcinomas have been used more and more frequently. These conservation methods have been used hoping to achieve long-term survival comparable to that obtained by mastectomy and breast preservation with good cosmetic results. This chapter reviews results at 5 and 10 years obtained in Europe by several authors concerning early breast infiltration carcinomas treated by limited surgery or without axillary dissection followed by irradiation

    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.

    Breast cancer is the most common cancer diagnosed in women. Each year, thousands die either because of disease progression or failure of treatment. Breast cancer is classified into different subtypes based on the molecular expression of estrogen receptor (ER), progesterone receptor, and/or human epidermal growth factor receptor 2 (HER2). These receptors represent important therapeutic targets either through monoclonal antibodies or through small-molecule inhibitors directed toward them. However, up to 40% of patients develop either a primary or a secondary resistance to the current treatments. Therefore, there is an urgent need for investigating new targets in order to overcome the resistance and/or enhance the current therapies. Cell cycle is altered in many human cancers, especially in breast cancer. Cyclin-dependent kinases (CDKs), especially CDK4 and CDK6, play a pivotal role in cell cycle progression that makes them potential targets for new promising therapies. CDK inhibition has shown strong antitumor activities, ranging from cytostatic antiproliferative effects to synergistic effects in combination with other antitumor drugs. In order to overcome the drawbacks of the first-generation CDK inhibitors, recently, new CDK inhibitors have emerged that are more selective to CDK4 and CDK6 such as palbociclib, which is the most advanced CDK4/6 inhibitor in trials. In preclinical studies, palbociclib has shown a very promising antitumor activity, especially against ERα+ breast cancer subtype. Palbociclib has gained world attention, and US the Food and Drug Administration has accelerated its approval for first-line treatment in combination with letrozole for the first-line systematic treatment of postmenopausal women with ERα+/HER2− locally advanced or metastatic breast cancer. In this review, we discuss the potential role of CDK inhibition in breast cancer treatment, and focus on palbociclib progress from preclinical studies to clinical trials with mentioning the

    2002-07-01

    Full Text Available Breast Cancer Susceptibility Gene1 (BRCA1 is a tumor suppressor gene for breast and ovarian cancers. The gene locates at chromosome 17q21 and encodes for 1863 amino acids protein. It is believed that BRCA1 protein is involved in many functions such as DNA repair, centrosome replication, cell cycle checkpoint and replication of other genes. More than 800 mutations have been found in the population with an increased risk of cancer incidence in their families. Germ-line mutation of BRCA1 accounts for 5-10 percent of all breast cancer cases. Epigenetic modifications also reduce the function of normal BRCA1 gene. Several methods are used for laboratory diagnosis of cancer-related mutations. The development of breast cancer in carriers at risk with BRCA1 mutations may be prevented by suitable prevention plans such as breast cancer screening, ovarian cancer screening, surgery and cancer chemotherapy.

    International Nuclear Information System (INIS)

    Fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) has been used successfully for the staging and re-staging of breast cancer. Another significant indication is the evaluation of therapy response. Only limited data are available on the use of FDG-PET in breast cancer after radiation therapy. The same holds true for chemotherapy. Only the therapy response in locally advanced breast cancer after chemotherapy has been investigated thoroughly. Histopathological response could be predicted with an accuracy of 88-91% after the first and second courses of therapy. A quantitative evaluation is, of course, a prerequisite when FDG-PET is used for therapy monitoring. Only a small number of studies have focussed on hormone therapy. In this context, a flare phenomenon with increasing standardised uptake values after initiation of tamoxifen therapy has been observed. More prospective multicentre trials will be needed to make FDG-PET a powerful tool in monitoring chemotherapy in breast cancer. (orig.)

    Full Text Available According to the experience of the researcher, an oncology nurse, women living in the rural areas of Thulamela municipality in the Limpopo Province, have many different perceptions of breast cancer. Perceptions are based on previous disease experiences. As with previous illnesses, changes in the breast caused by breast cancer are self-managed and treated. When these women seek medical advice for breast cancer related problems, they already have advanced cancer. The purpose of the study was to investigate if women are knowledgeable of the signs and symptoms of breast cancer, breast self-examination, as well as appropriate health care to take responsibility to prevent admission with advanced breast cancer. The research study was an exploratory and contextual survey. The sampling method was convenient (n=200. Data were gathered during a structured interview using a checklist. Data analysis was done by means of descriptive statistics. The results of the study indicated a low level of knowledge regarding the signs and symptoms of breast cancer. The average level of knowledge for the signs and symptoms of breast cancer was less than 10% (n=20. With regards to breast self-examination the results varied between 8.5% (n=17 and 13% (n=26. Biomedical medicine was the preferred treatment choice for the majority of the respondents. The study provided evidence that women were unable to take responsibility for their breast health. Their lack of knowledge of the signs and symptoms of breast cancer and breast self-examination would not enable them to prevent presenting with advanced disease. A breast health care strategy for women living in Thulamela should be designed, implemented and evaluated to prevent presentation with advanced breast cancer.

    Although more widespread screening and routine adjuvant therapy has improved the outcome for breast cancer patients in recent years, there remains considerable scope for improving the efficacy, safety and tolerability of adjuvant therapy in the early stage disease and the treatment of advanced disease. Toremifene is a selective estrogen receptor modifier (SERM) that has been widely used for decades in hormone receptor positive breast cancer both in early and late stage disease. Its efficacy has been well established in nine prospective randomized phase III trials compared to tamoxifen involving more than 5500 patients, as well as in several large uncontrolled and non-randomized studies. Although most studies show therapeutic equivalence between the two SERMs, some show an advantage for toremifene. Several meta-analyses have also confirmed that the efficacy of toremifene is at least as good as that of tamoxifen. In terms of safety and tolerability toremifene is broadly similar to tamoxifen although there is some evidence that toremifene is less likely to cause uterine neoplasms, serious vascular events and it has a more positive effect on serum lipids than does tamoxifen. Toremifene is therefore effective and safe in the treatment of breast cancer. It provides not only a useful therapeutic alternative to tamoxifen, but may bring specific benefits. PMID:25114854

    Despite recent advances in treatment, breast cancer remains a serious health threat for women. Traditional chemotherapies are limited by a lack of specificity for tumor cells and the cell cycle dependence of many chemotherapeutic agents. Here we report a novel strategy to help overcome these limitations. Using triplex-forming oligonucleotides (TFOs) to direct DNA damage site-specifically to oncogenes overexpressed in human breast cancer cells, we show that the effectiveness of the anticancer nucleoside analogue gemcitabine can be improved significantly. TFOs targeted to the promoter region of c-myc directly inhibited gene expression by approximately 40%. When used in combination, specific TFOs increased the incorporation of gemcitabine at the targeted site approximately 4-fold, presumably due to induction of replication-independent DNA synthesis. Cells treated with TFOs and gemcitabine in combination showed a reduction in both cell survival and capacity for anchorage-independent growth (approximately 19% of untreated cells). This combination affected the tumorigenic potential of these cancer cells to a significantly greater extent than either treatment alone. This novel strategy may be used to increase the range of effectiveness of antitumor nucleosides in any tumor which overexpresses a targetable oncogene. Multifaceted chemotherapeutic approaches such as this, coupled with triplex-directed gene targeting, may lead to more than incremental improvements in nonsurgical treatment of breast tumors.

    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.

    The mammalian transcriptome has recently been revealed to encompass a large number of noncoding RNAs (ncRNAs) that play a variety of important regulatory roles in gene expression and other biological processes. MicroRNAs (miRNAs), the best studied of the short noncoding RNAs (sncRNAs), have been extensively characterized with regard to their biogenesis, function and importance in tumorigenesis. Another class of sncRNAs called piwi-interacting RNAs (piRNAs) has also gained attention recently in cancer research owing to their critical role in stem cell regulation. Long noncoding RNAs (lncRNAs) of >200 nucleotides in length have recently emerged as key regulators of developmental processes, including mammary gland development. lncRNA dysregulation has also been implicated in the development of various cancers, including breast cancer. In this review, we describe and discuss the roles of sncRNAs (including miRNAs and piRNAs) and lncRNAs in the initiation and progression of breast tumorigenesis, with a focus on outlining the molecular mechanisms of oncogenic and tumor-suppressor ncRNAs. Moreover, the current and potential future applications of ncRNAs to clinical breast cancer research are also discussed, with an emphasis on ncRNA-based diagnosis, prognosis and future therapeutics.

    The aim of this study was to investigate the potential of texture analysis, applied to dynamic contrast-enhanced MRI (DCE-MRI), to predict the clinical and pathological response to neoadjuvant chemotherapy (NAC) in patients with locally advanced breast cancer (LABC) before NAC is started. Fifty-eight patients with LABC were classified on the basis of their clinical response according to the Response Evaluation Criteria in Solid Tumors (RECIST) guidelines after four cycles of NAC, and according to their pathological response after surgery. T1 -weighted DCE-MRI with a temporal resolution of 1 min was acquired on a 3-T Siemens Trio scanner using a dedicated four-channel breast coil before the onset of treatment. Each lesion was segmented semi-automatically using the 2-min post-contrast subtracted image. Sixteen texture features were obtained at each non-subtracted post-contrast time point using a gray level co-occurrence matrix. Appropriate statistical analyses were performed and false discovery rate-based q values were reported to correct for multiple comparisons. Statistically significant results were found at 1-3 min post-contrast for various texture features for the prediction of both the clinical and pathological response. In particular, eight texture features were found to be statistically significant at 2 min post-contrast, the most significant feature yielding an area under the curve (AUC) of 0.77 for response prediction for stable disease versus complete responders after four cycles of NAC. In addition, four texture features were found to be significant at the same time point, with an AUC of 0.69 for response prediction using the most significant feature for classification based on the pathological response. Our results suggest that texture analysis could provide clinicians with additional information to increase the accuracy of prediction of an individual response before NAC is started. PMID:24840393

    Purpose: To assess the diagnostic performance of pretreatment {sup 18}F-fluorodeoxyglucose positron emission tomography/computed tomography ({sup 18}F-FDG PET/CT) and its impact on radiation therapy treatment decisions in patients with locally advanced breast cancer (LABC). Methods and Materials: Patients with LABC with Eastern Cooperative Oncology Group performance status <2 and no contraindication to neoadjuvant chemotherapy, surgery, and adjuvant radiation therapy were enrolled on a prospective trial. All patients had pretreatment conventional imaging (CI) performed, including bilateral breast mammography and ultrasound, bone scan, and CT chest, abdomen, and pelvis scans performed. Informed consent was obtained before enrolment. Pretreatment whole-body {sup 18}F-FDG PET/CT scans were performed on all patients, and results were compared with CI findings. Results: A total of 154 patients with LABC with no clinical or radiologic evidence of distant metastases on CI were enrolled. Median age was 49 years (range, 26-70 years). Imaging with PET/CT detected distant metastatic disease and/or locoregional disease not visualized on CI in 32 patients (20.8%). Distant metastatic disease was detected in 17 patients (11.0%): 6 had bony metastases, 5 had intrathoracic metastases (pulmonary/mediastinal), 2 had distant nodal metastases, 2 had liver metastases, 1 had pulmonary and bony metastases, and 1 had mediastinal and distant nodal metastases. Of the remaining 139 patients, nodal disease outside conventional radiation therapy fields was detected on PET/CT in 15 patients (10.8%), with involvement of ipsilateral internal mammary nodes in 13 and ipsilateral level 5 cervical nodes in 2. Conclusions: Imaging with PET/CT provides superior diagnostic and staging information in patients with LABC compared with CI, which has significant therapeutic implications with respect to radiation therapy management. Imaging with PET/CT should be considered in all patients undergoing primary
