NCT ID: NCT03402529 Recruiting - Breast Cancer Clinical Trials

Added Value of Contrast Enhanced Spectral Mammography, CESM. A Pilot Study.

Start date: November 28, 2017
Phase: N/A
Study type: Interventional

Introduction: To avoid unnecessary mastectomies and reoperations a correct size assessment of malignant lesions in breast is required. Sometimes a supplementary MRI is therefore recommended. However, at our unit MRI is not easily available. Contrast enhanced spectral mammography (CESM) has in smaller studies been shown to be equal to MRI regarding sensitivity and specificity. Size assessment using contrast-based modalities as CESM has also been shown to be significantly more accurate than using mammography. Prospective randomized studies using CESM are lacking. Aim: The aim of the study is to evaluate the added value of CESM in diagnostics of breast cancer and choice of operation; partial mastectomy or mastectomy. A pilot study of 50 patients will be conducted to prepare for a larger prospective randomized study. Method: Patients found with breast cancer after diagnostics with mammography, ultrasound and core biopsy, and whom are recommended primary surgery, will be enrolled in the study. A supplementary examination with CESM will be performed. Preoperative extent of the malignant lesions are estimated with each modality and is later compared with the extent measured in post-operative PAD. Data on weight, length, age at menopaus, use of contraceptive pills, HRT or endocrine therapy, breast volume and density is collected, as well as data of diagnosis (ductal or lobular carcinoma), surrounding DCIS, histological grade, ER, PgR, Her2 expression and Ki67 index. In this pilot study sensitivity and specificity for each modality is calculated. Multivariate analysis will be performed regarding influential factors. Pearson correlation coefficient will be calculated for each modality regarding size assessment of the malignant lesions in comparison with definitive PAD.

NCT ID: NCT03401034 Completed - Breast Cancer Clinical Trials

Influence of Lifestyle, Inflammatory Biomarkers, and Genetic Factors on Long-term Breast Cancer Prognosis

Start date: August 1, 2002
Phase: N/A
Study type: Observational

The MARIEplus study is a prospective cohort of breast cancer patients recruited into the MARIE (Mamma Carcinoma Risk factor InvEstigation) study, a population-based case-control study of breast cancer conducted in two German study regions, Hansestadt Hamburg and Rhine-Neckar-Karlsruhe (RNK) region. Participants were identified through participating clinics and the Hamburg cancer registry between January 1st, 2001 and September 30th, 2005 in Hamburg and between August 1st, 2002 and July 31st, 2005 in the RNK study region. Patients were aged 50-74 years at histologically confirmed primary invasive (stages I to IV) or in situ breast tumor (stage 0). Comprehensive information on demographic, socio-economic, and lifestyle factors was collected at multiple time points: at recruitment by a standardized face-to-face interview and at follow-up median 6 years as well as 11 years later using computer assisted telephone interview. Vital status was assessed in 2009 and again in 2015 via the population registries and causes of death were obtained from death certificates and coded according to the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10). Information on the clinical course was abstracted from medical records to verify clinical events either self-reported in follow-up interviews or reported by treating physicians. The studies were approved by the ethics committee of the University of Heidelberg and the University of Hamburg and conducted in agreement with the Helsinki Declaration. Written informed consent was provided by all participants at baseline and during follow-up. The primary objectives of this study are - To assess the association of modifiable lifestyle factors and personal factors, including BMI, diet, physical activity, tobacco and alcohol use, menopausal hormone therapy, socioeconomic status, with breast cancer survival, overall and according to tumor type, after accounting for established prognostic factors. - To examine the influence of genetic variants on breast cancer relapse and survival - To assess the association of lifestyle factors and their changes in the course of survivorship on subsequent breast cancer prognosis. - To assess the individual and combined association of inflammation/metabolic biomarkers as well as changes in their serum levels with subsequent breast cancer prognosis overall and according to tumor type. - To assess whether and to what extent the associations between breast cancer prognosis and lifestyle factors and/or their changes are mediated by circulating biomarker levels.

A Phase Ib/II Trial of Gedatolisib, Hydroxychloroquine or the Combination for Prevention of Recurrent Breast Cancer ("GLACIER")

GLACIER
Start date: February 2018
Phase: Phase 1/Phase 2
Study type: Interventional

The specific purposes of this study are to: 1) Determine the best dose of gedatolisib (GED) to give in combination with hydroxychloroquine (HCQ, at a fixed dose) to people with disseminated tumor cells detected in their pone marrow. 2)Determine how well these drugs do at reducing the number of disseminated tumor cells in the bone marrow. 3) Determine the type and degree of side effects of these drugs in people who have completed treatment for breast cancer.

Gradient-Echo Spectroscopic Imaging Study of Saturated Fat and Breast Cancer

Start date: June 2018
Phase: N/A
Study type: Interventional

The role of fat in breast cancer development and growth has been studied extensively using body mass index, a measure of whole body fatness, and dietary fat intake in a number of epidemiological studies. However, there is a paucity of studies, on an individual level, to assess the role of breast fat itself in breast cancer due to lack of a non-invasive and fast measurement method. Since breast fibroglandular cells are surrounded by breast fat cells, the characteristics of breast fat may have a stronger relationship with breast cancer development, as supported by recent studies showing that a majority of breast cancer develops at the interface between fibroglandular tissue and adipose tissue. However, it is not trivial to study the role of breast fat, mainly due to the lack of a non-invasive and fast measurement method sensitive enough to important features of breast fat, such as types of fat.Recently, we have developed a rapid MRI method, referred to as Gradient-echo Spectroscopic Imaging (GSI), to measure fatty acid composition during clinical breast MRI exams. GSI can provide map of saturated fat and unsaturated fats in the breast adipose tissue without performing tissue biopsy. Our pilot study found that the postmenopausal women with aggressive breast cancer, known as invasive ductal carcinoma, have a significantly higher percentage of saturated fat in their breast adipose tissue than the postmenopausal women with only benign lesions.

Pilot Study Describing the Early Evolution of the Sexual Function of Patients Receiving Adjuvant Hormone Therapy for Breast Cancer

Start date: January 15, 2018
Phase: N/A
Study type: Observational

The 2014-2019 cancer plan emphasizes the need to "reduce the impact of cancer on personal life". The impact of cancer on sexuality is multifactorial: fatigue, anxiety, impaired body image, chemotherapy treatment. None of these studies specifically assessed the early impact on the quality of sexual life of patients. The purpose of this study is to describe to describe the early evolution of the quality of sexual life of patients receiving adjuvant hormone therapy for breast cancer.
