Breast CancerThe purpose of this study is to observe clinical outcomes of metastatic breast cancer patients whose tumors overexpress the Her2neu protein and are being treated with trastuzumab (Herceptin)either alone or combination with chemotherapy or hormonal therapy.
Morbidity Following the Diagnosis and Treatment of Patients With Breast Cancer
Breast CancerLymphedema2 moreThis study will examine the frequency and severity of problems in women with breast cancer during the first year after initial medical treatment, including: Physical impairments, such as loss of strength or flexibility, increased weight and swelling Symptom distress, such as pain, fatigue and weakness. Functional limitations and disabilities, such as loss of independence in activities of daily living (e.g., grooming, bathing, dressing, driving a car), work and social and recreational activities. It will identify factors associated with these problems and try to determine their relationship to them. Patients 18 years of age and older with stage I, II, III or IV breast cancer may be eligible for this study. Participants will be drawn from patients referred to the National Naval Medical Center for diagnosis and treatment during 2000-20001. Participants will be interviewed and their medical records reviewed for past medical history, history of the present illness and social and recreational history. They will be seen five times over a 1-year period (initial visit and at 3, 6, 9, and 12 months), for 30-minute visits, which will include the following: Interview about past medical history and present illness, social and recreational activities, functional independence at work and during activities of daily living. Complete health survey and upper limb disability questionnaire; physical activity questionnaire to be completed at 6 and 12 months after medical treatment begins. The questionnaires take about 30 to 40 minutes to complete. Upper body examination, including pain measurement using a 10-point scale, an upper limb lift test, and measures of upper limb volume and girth.
Correlation of 16α-[18F]Fluoro-17β-estradiol PET Imaging With ESR1 Mutation
Breast CancerThe propose of this prospective study focuses on the role of [18F]FES PET imaging in patients with breast cancer who might receive or are receiving hormone therapy. First, we will develop and optimize the radiosynthesis and quality control tests of [18F]FES in conditions that meet good manufacturing practice (GMP) requirements. Secondly, patients with or without metastatic breast cancer will be enrolled for the conduction of human study. [18F]FES PET imaging will be performed on patients before the initiation of hormone therapy to predict the prognosis and therapeutic response to hormone therapy. The [18F]FES PET results will be compared with ER status obtained by immunohistochemical (IHC) staining on surgically obtained specimens. Moreover, in patients with progression of metastatic disease, the [18F]FES PET will be correlated with ESR1 gene mutation, which is one of the mechanisms for resistance to hormone therapy.
ALEXANDRIA Study Egypt
Breast CancerBreast Cancer (BC) is one of the most frequent cancers in women and is the most frequent cause of death in the female population. It represents 18% of all female cancers in the world.1 The incidence varies in different populations with almost half of the cases having their origin in North America and Western Europe. In Egypt, according to the National Population-Based Cancer Registry published in 2014, BC was the most frequent cancer among females representing 32% of all female cancers2 Metastatic disease occurs in approximately 20-50% of patients with early BC history and in 6-10% of newly diagnosed BC cases.3 Since patients with metastatic BC form a heterogeneous population, treatment recommendations ought to be made on an individual basis, considering hormone receptor (HR) and human epidermal growth factor receptor 2 (HER2) status, metastasis-free interval (MFI), response to and cumulative doses of previous therapy, location and extent of metastases and symptoms 4,5. Two thirds of BC patients have HR-positive (HR+) tumors 6, for whom endocrine therapy (ET) is the preferred initial treatment for metastatic disease as recommended in the treatment guidelines, even in the presence of visceral metastases 4, 6, 7. The use of ET is supported by data showing a therapeutic benefit with less toxicity and better quality of life in comparison to chemotherapy (CT) 5,8,9. Nevertheless, it is generally thought that CT is associated with greater and earlier tumor response, especially in the case of high burden of disease. For patients with hormone receptor-positive and HER2+ disease CT plus HER2-targeted therapy was strongly recommended, except for highly selected cases for whom clinicians may offer ET 10. On the contrary, for women with hormone receptor-positive HER2-negative disease who are the scope of this study the question of whether to use CT or ET as first-line treatment for metastatic BC remains, to date, partially unresolved.
Evaluation of NeoNavia® Biopsy System in Axillary Lymph Nodes
Breast CancerThe aim of the study is to document performance characteristics of a biopsy device indicated for use in axillary lymph nodes, to provide basic insights into the complexity of axillary biopsy procedures and generate hypothesis for further larger comparative trials. This is a Sponsor-initiated prospective, multicenter, registry trial. Patients that present with suspicious axillary lymph nodes at the time of breast cancer diagnosis undergo axillary sampling using the NeoNavia biopsy system. This is in accordance with clinical routine and current clinical guidelines. The system incorporates a new mechanism for controllable and precise needle insertion and a newly developed sampling needle for high yield sampling acquisition. It is approved for use in the breast and axillary lymph nodes.
Trends of Mastectomy and Breast-Conserving Surgery in Female Breast Cancer Patients
Breast CancerBreast Neoplasms1 moreBreast cancer is the most common cancer in women across the world, accounting for 25.2% of cancer cases among females and 14.7% of cancer-related deaths among females worldwide. The survival rates are markedly lower in the developing countries compared to developed countries, as well as the age at diagnosis. Core management of breast cancer includes surgical removal of the tumor either by breast-conserving surgery (BCS) or mastectomy (removal of the whole breast). Choosing between these two procedures may be influenced by factors that have yet to be studied in Saudi Arabia. The investigators aimed to determine the prevalence of BCS and mastectomy and the factors that may influence the choice of procedure. This retrospective study was carried out by reviewing the records of female breast cancer patients who underwent BCS or mastectomy at King Abdulaziz University Hospital between 2009 to June 2017, excluding those with metastasis (distant spread of the cancer) or recurrence. Using frequencies for the rate, and multivariate tests, the investigators analyzed different demographic, clinicopathological, and radiological factors to detect correlations with procedure choice.
Comorbidities and Health Care Services Utilisation Among Long-term Breast Cancer Survivors
Breast CancerThe increased likelihood of survival can be explained by numerous factors, such as improvements in breast cancer screening and advances in diagnosis and treatment and aging. This phenomenon is associated with comorbidity due to cancer treatment and external factors like aging or lifestyle. Little is known about how these women follow-up their disease, their pattern of use of health resources and their met and unmet needs. Studying the health needs of these women is a cancer-related priority for Cancer Organizations.The project is aimed at: 1) Describing the comorbidities and patterns of use of primary and specialized care in women who have survived a breast cancer for at least five years; 2) Comparing the comorbidities and patterns of use of long time breast cancer survivors with women without a cancer diagnosis; and 3) Estimating the use of resources in long time survivors of breast cancer adjusted for survival-time and comorbidities.
Pregnant Exposure to Persistent Organic Pollutants
Breast CancerBreast cancer, the first female cancer, affects one in eight women in her lifetime. The increase and uneven distribution of its prevalence throughout the world cannot be fully explained either by the increase in life expectancy, or by genetic factors present in less than 10% of cases, or by early detection, or by the use of hormone therapy for menopause at certain periods of time. Numerous experimental and epidemiological arguments, as well as the increased risk of breast cancer in women after 50 years of age who were exposed in utero to Distilbene prescribed for their mothers in the 1950s to 75's, suggest the involvement of environmental factors involved in early development (nutrition, alcohol, tobacco, chemical pollutants) that may act as endocrine disruptors, estrogenomimetic or intervening on other nuclear receptors such as the However, the formal demonstration of the deleterious physiopathological role of such exposure comes up against methodological difficulties in epidemiological terms: first of all, the fact that correlation is sought at the time of the discovery of breast cancer when there are critical windows of exposure (fetal, perinatal, peripubertal and pregnant) and that persistent organic products or POPs, most often lipids, are present. The objective of this project is to correlate the per-gravidic exposure to POPs (dioxins, dioxinlike, polychlorinated bisphenyls, organochlorine pesticides and flame-retardant polybrominated derivatives) and the development, within 15 years of delivery, of breast cancer, taking into account the confounding factors of classical breast cancer risk (age, reproductive events, etc.). This project benefits on the one hand from a cord blood bank set up between 2002 and 2005 (6,242 samples) carried out at the Nice University Hospital and the Grasse University Hospital, during a PHRC and on the other hand from the cancer observatory / CRISAP of the PACA Corsica region, exhaustive to more than 92% since 2005, registers which will be cross-referenced and whose cancer cases (N) will be compared to controls. The assays will be carried out after purification, using high-resolution mass spectrometry gas chromatography coupling, the quantification being carried out according to the principle of isotopic dilution. They will be carried out by LABERCA in Nantes, the national reference laboratory of the French Health Agencies ANSES and INVS and also involved in various European projects. Concentrations related to blood lipids will be expressed in quartile and analyzed separately or combined with a cumulative score taking into account confounding risk factors for breast cancer and the geolocation of the initial and final residence in relation to the incinerator of the City of Nice (Department of Public Health CHU of Nice).
Prognostic and Predictive Factors for Small Breast Tumors
Breast CancerBecause of mammography screening increasingly more women are diagnosed with centimeter or subcentimeter node-negative breast cancer (i.e., T1abN0); these tumors account for approximately 19% of all newly diagnosed breast cancers in Sweden. Although the long term relapse-free survival rates among patients with such tumors is as high as ≥90%, some reports suggest that certain patient subgroups may have rates <75%. Firmly established prognostic and predictive factors for patients with T1abN0 tumors are, however, lacking. This is a nationwide, register-based cohort study investigating prognostic and predictive factors in women with centimeter or subcentimeter breast cancer. The study hypotheses are: 1) Established prognostic and/or predictive factors in overall breast cancer are prognostic and/or predictive factors also in centimeter or subcentimeter node-negative breast cancer; 2) The established relative reduction in risk of recurrence and death of adjuvant treatment for overall breast cancer are similar in centimeter or subcentimeter node-negative breast cancer.
