NCT ID: NCT03912948 Recruiting - Breast Cancer Clinical Trials

Chronic Pain and Minor Breast Cancer Surgery

Start date: April 1, 2019
Study type: Observational

Breast cancer is the most frequent in women. Early diagnosis and recent treatments have improved overall mortality. However, chronic pain (pain lasting more than 3 months after surgery) remains a public health problem with impact on quality of life for these patients. The incidence of pain has been reported up to 25 to 60% of patients in the literature, even many years after a radical mastectomy (Gartner et al. JAMA 2009;302:1985-92). The neuropathic component of the pain is usually underestimated. In a prospective cohort study we have demonstrated that 43% of patient needed on average 5mg of morphine intravenously in the recovery room after a conservative breast cancer surgery, despite a multimodal regimen of analgesic drugs (Fuzier et al. J Anesth 2017;31:246-54). In the same study, 40% of patients reported persistent pain 3 months after the surgery. To improve the analgesia in such a population, we decided to introduce regional analgesia technique (serratus block) systematically. This became our gold standard in our daily practice. We would like to assess the efficacy of such regional analgesia techniques on opioids consumption in the recovery room and the incidence of pain 3 months after conservative breast cancer surgery.

NCT ID: NCT03910595 Recruiting - Breast Cancer Clinical Trials

Efficacy Study of Mepitel Film the Prophylaxis of Radiation-Induced Skin Reactions in Breast Cancer Patients

Start date: March 14, 2019
Phase: Phase 2
Study type: Interventional

In patients undergoing adjuvant radiotherapy for breast cancer, radiation-induced skin toxicities are a common occurrence and adversely impact patients' quality of life (QOL). In the last decade, there have been no significant advances in preventing or treating radiation-induced skin toxicities. Recently, a phase III randomized trial by Herst et al. (n=78) in New Zealand showed that the prophylactic use of Mepitel Film reduced skin reaction severity by 92% compared to skin treated only with aqueous cream. Mepitel film has not been widely adopted in North America. To validate the efficacy of the film and guide the development of a larger multi-centre phase II study, a pilot study testing the efficacy of the film is proposed. In the study, 30 patients will have the film applied on their breast for the duration of radiation treatment and their skin reactions will be assessed throughout the treatment and after the treatment. The investigators hypothesize that the severity and incidence rates of skin reactions for patients using Mepitel film will be lower when compared to real world data from our centre, and that cosmetic outcomes will be improved with the film.

NCT ID: NCT03908528 Recruiting - Breast Cancer Clinical Trials

Alpha-Lipoic Acid in Breast Cancer Patients

Start date: March 1, 2019
Phase: N/A
Study type: Interventional

• Investigate the ability of alpha lipoic acid to counter act anthracycline associated cardiotoxicity and cumulative taxens-related PN in patients with breast cancer.

NCT ID: NCT03907098 Recruiting - Breast Cancer Clinical Trials

Endostar in Combination With Chemotherapy in HER-2 Negative Advanced Breast Cancer

Start date: June 30, 2016
Phase: Phase 2
Study type: Interventional

This research study is studying endostar in combination with chemotherapy as a possible treatment for HER-2 negative advanced breast cancer.

NCT ID: NCT03904173 Recruiting - Breast Cancer Clinical Trials

Establishment of Molecular Profiling for Individual Clinical Routine Treatment Decision in Early Breast Cancer

Start date: October 29, 2018
Study type: Observational

The present project focuses on how to reduce both over- and under-treatment with adjuvant chemotherapy to a large number of breast cancer patients in Norway. A set of primary tumor prognostic factors can be analysed for potential achievement of this. Furthermore, multi-parameter tests, including detailed molecular analysis of the primary tumors might further improve the selection of patients among the lymph node negative. The study seeks to advance the development of personalised treatment of patients with early breast cancer without lymph node metastasis, by the evaluation of multi-parameter analysis as a means of identifying those patients who are likely to benefit from chemotherapy whilst sparing those who are unlikely to do so from an unnecessary and unpleasant treatment.

NCT ID: NCT03896958 Recruiting - Breast Cancer Clinical Trials

The PIONEER Initiative: Precision Insights On N-of-1 Ex Vivo Effectiveness Research Based on Individual Tumor Ownership (Precision Oncology)

Start date: March 21, 2019
Study type: Observational

The PIONEER Initiative stands for Precision Insights On N-of-1 Ex vivo Effectiveness Research. The PIONEER Initiative is designed to provide access to functional precision medicine to any cancer patient with any tumor at any medical facility. Tumor tissue is saved at time of biopsy or surgery in multiple formats, including fresh and cryopreserved as a living biospecimen. SpeciCare assists with access to clinical records in order to provide information back to the patient and the patient's clinical care team. The biospecimen tumor tissue is stored in a bio-storage facility and can be shipped anywhere the patient and the clinical team require for further testing. Additionally, the cryopreservation of the biospecimen allows for decisions about testing to be made at a later date. It also facilitates participation in clinical trials. The ability to return research information from this repository back to the patient is the primary end point of the study. The secondary end point is the subjective assessment by the patient and his or her physician as to the potential benefit that this additional information provides over standard of care. Overall the goal of PIONEER is to enable best in class functional precision testing of a patient's tumor tissue to help guide optimal therapy (to date this type of analysis includes organoid drug screening approaches in addition to traditional genomic profiling).

NCT ID: NCT03887598 Recruiting - Breast Cancer Clinical Trials

Application of Ultrasound Artificial Intelligence and Elastography in Differential Diagnosis of Breast Nodules

Start date: January 18, 2019
Study type: Observational

The application of computer-aided diagnosis (CAD) technology "S-Detect" enables qualitative and quantitative automated analysis of ultrasound images to obtain objective, repeatable and more accurate diagnostic results. The Elastic Contrast Index (ECI) technique, unlike conventional strain-elastic imaging techniques, can evaluate the elastic distribution in the region of interest. The purpose of the study was to evaluate the differential diagnosis value of ultrasound S-Detect technology for benign and malignant breast nodules and evaluate the differential diagnosis consistency of the ultrasound S-Detect technique and the examiner for benign and malignant breast nodules and explore the differential diagnosis value of Samsung ultrasound elastic contrast Index (ECI) technique for benign and malignant breast nodules.

NCT ID: NCT03885648 Recruiting - Breast Cancer Clinical Trials

Breast Cancer and Its Relationship With the Microbiota

Start date: January 1, 2018
Study type: Observational

Breast cancer ranks first in women, and is the second cause of death in this gender. In addition to genetics, the environment contributes to the development of the disease, although the factors involved are not well known. Among the latter is the influence of microorganisms and, therefore, attention is recently being paid to the mammary microbiota. The hypothesis of this study is that the risk of breast cancer could be associated with the composition and functionality of the mammary/gut microbiota, and that exposure to environmental contaminants (endocrine disruptors, EDCs) might contribute to alter the microbiota. This is a case-control clinical study that will be performed in women between 25 and 70 years of age. Cases will be women diagnosed and surgically intervened of breast cancer (stages I and II). Women with antecedents of cancer or advanced tumor stage (metastasis), or who have received antibiotic treatment within 3 months prior to recruitment, or any neoadjuvant therapy, will be excluded. Controls will be women surgically intervened of breast augmentation or reduction. Women with oncological, gynecological or endocrine history, and those who have received antibiotic treatment within 3 months prior to recruitment will also be excluded. Blood, urine, breast tissue and stool samples will be collected. Data regarding anthropometric, sociodemographic, reproductive history, tumor features and dietary habits will be gathered. Metabolomic studies will be carried out in stool and breast tissue samples. Metagenomic studies will also be performed in stool and breast tissue samples to ascertain the viral, fungal, bacterial and archaea populations of the microbiota. Quantitation of estrogens, estrogen metabolites and EDCs in samples of serum, urine and breast tissue will also be performed. This is the first time that the contribution of bacteria, archaea, viruses and fungi together with their alteration by environmental contaminants to the risk of breast cancer will be evaluated in the same study. Results obtained could contribute to elucidate risk factors, improve the prognosis, as well as to propose novel intervention studies in this disease.
