Nanomedicines are currently being developed in the treatment of cancer due to their pharmacological advantages over traditional formulations; they provide a shorter infusion time and lower risks of hypersensitivity reactions associated with commonly used solvents. Nab-paclitaxel is a nanoparticle albumin-bound particle form of paclitaxel that is thought to exploit natural albumin pathways to enhance the selective uptake and accumulation of paclitaxel at the site of the tumour, thus reducing its diffusion to normal tissues. Nab-paclitaxel has been approved for the treatment of metastatic breast cancer patients who have failed first-line treatment for metastatic disease and for whom standard, anthracycline-containing therapy is not indicated. SPARC is a cysteine rich acid protein that is overexpressed in a broad proportion of solid tumours. Expression of this protein could sensitize tumour cells to antitumor activity of Nab-paclitaxel, due to its union through albumin-binding to this protein. First-line clinical trials have been developed with different Nab-paclitaxel regimens and also in combination with different chemotherapies and trastuzumab, showing a high level of efficacy. Toxicity profile of Nab-paclitaxel is well characterized with significantly less haematological toxicities compared with conventional paclitaxel. Nab-paclitaxel derived grade III neuropathy is short-lasting and more reversible than conventional paclitaxel-derived neuropathy, probably due to absence of Cremophor solvent, or due to paclitaxel itself. However there is still a lack of clinical and physiological characterisation of Nab-paclitaxel induced neuropathy. The current used tools for early detection and continuous evaluation of neurotoxicity are not optimal. Most used toxicity scales are limited, as they do not provide a detailed information of the severity of the neuropathy, its impact on quality of life, or physiopathology mechanisms. In addition, an inter-individual variability exists in terms of neurotoxicity predisposition when taxanes are used; it could be related to polymorphic differences in genes implicated in transport and metabolism of these drugs.
Establishment of a tumor bank, consisting of blood samples of tumor patients and healthy people as controls. The blood samples will be collected systematically together with the corresponding clinical data. The biological samples, the clinical date together with prospective experimental date constitute the entity of the tumor bank.
To evaluate the effectiveness of preventing Grade II or greater radiation dermatitis induced by adjuvant radiation therapy in women with breast cancer.
The purpose of this study is to look at the rates of acute and long term adverse events of postoperative proton radiotherapy for complex loco-regional irradiation in women with loco-regionally advanced breast cancer. This study specifically includes longitudinal follow up to assess the incidence of cardiac mortality and second malignant neoplasms at 10 and 15 years following proton therapy(PT).
Helical tomotherapy nowadays provides the most precise data on radiotherapy (RT) dose delivered to each region of the heart in left-sided breast cancer therapy, which allows greater sparing of the heart from doses associated with increased complications. However, heart disease shows a wide spectrum of pathologies, and multiple risk factors related. The damage of the myocytes may lead to not only myocardial perfusion defects, but also in functional deterioration, or even in biomarkers. In this study, we will monitor cardiovascular (CV) risk factors, metabolism, biomarkers, myocardial perfusion defect patterns, and cardiac functional parameters, in order to delineate of RT-related effects and clinical impacts. Objective: The pilot study aims to investigate the correlation of post-tomotherapy cardiovascular effects with myocardial perfusion and cardiac functional studies. Methods: The study plans to enroll female breast cancer patients who will undergo local RT after their surgery. Patients will receive global risk scoring assessment (Framingham Risk Score, FRS), blood sampling for basic biochemistry, inflammatory biomarker, and myocardial perfusion image (MPI) at the time points of before and after RT. The results of MPI will be analyzed in qualitative visual interpretation of perfusion patterns, and functional quantitative data for cardiac functional parameters as well. The patients will be regular followed-up in CV OPD. The association between baseline and follow-up MPI, biomarker and clinical presentation will be further investigated.
To see the impact of obesity on the efficacy of adjuvant endocrine therapy with aromatase inhibitors in postmenopausal patients with early breast cancer in terms of: i) Locoregional recurrence ii) Distant metastases iii) Disease-free survival iv) Overall survival
This randomized phase II trial studies the effects of erismodegib (LDE225) on disseminated tumor cells (DTCs) in patients with stage III-III estrogen receptor (ER)-negative and human epidermal growth factor receptor 2 (HER2)-negative breast cancer. The presence of DTCs after completing treatment for breast cancer may be linked to recurrence of the disease. LDE225 may eliminate DTCs in bone marrow and reduce the risk of recurrence.
The investigators will assess changes in breast appearance, graft retention and quality of life over one year in patients who have received direct autologous adipose tissue injection for the treatment of objectionable post-surgical breast deformities. These patients have undergone the resection of breast tissue to treat either benign or malignant breast disease.
This pilot clinical trial studies light-scattering spectroscopy in finding disease in patients with stage II-III breast cancer. Diagnostic procedures, such as light-scattering spectroscopy, may help find and diagnose breast cancer
