This prospective, multicentric single arm phase IV study is based on the protocol of the international TARGIT-A and TARGIT-E study. Patients ≥ 50 years with small, low-risk breast cancer who are operated but not irradiated show local relapse rates around 6% after 5 years. With adjuvant whole breast radiotherapy (WBRT) the local relapse rate drops to under 1% after 5 years under Tamoxifen (4). It has been demonstrated (6, 9, 10) that the efficacy of radiation of the tumor bed only in a selected group can be non-inferior to WBRT. The TARGIT C study should confirm the efficacy of a single dose of intraoperative radiotherapy (IORT) in a well selected group of patients with small breast cancer and absence of risk factors. In presence of risk factors postoperative WBRT will be added to complete the radiotherapeutic treatment according to international guidelines. Endpoints are the local relapse rate (within 2 cm of the tumor bed), ipsilateral relapse, cancer-specific and overall survival and contralateral breast cancer as well as documentation of quality of life and cosmetic outcome. The expected local relapse rates are 0.825/1.375% after 3/5 years, respectively. Discontinuation of the trial is scheduled if rates of local relapse rates rise to 1.55/2.4/4% after 1/3/5 years. Power calculations result in 387 patients with a calculated dropout and loss to follow-up rate of 10%, an alpha of 0.05 and a beta of 0.10. There will be only a pre-pathology stratum. It is a pragmatic trial in which each participating centre has the option to modify entry criteria and criteria for WBRT according to this core protocol after consultation with the steering committee and local ethics committee (e.g. size, free margins). Only centers with access to the Intrabeam® system (Carl Zeiss) can recruit patients into the trial.
The investigators want to study whether Vitamin D and melatonin can reduce the growth of cancer cells in women with breast cancer. Studies using cell cultures and animals have shown that Vitamin D can reduce the spread of cancer. Studies in people have shown that exposure to sun and eating foods containing high levels of Vitamin D can protect against cancer. As well, researchers have noticed that an increase in melatonin levels appears to lower the risk of getting cancer. Melatonin is a hormone secreted by the body during the night while sleeping. Women with cancer proven by breast biopsy who are planned for surgery will be included. The investigators want to see if treatment with Vitamin D (2000 IU daily), or melatonin (20 mg daily), or both pills together, reduces the growth of cancer cells when compared to treatment with sugar pills. All women will receive identical appearing pills for approximately four weeks. The investigators will measure a tumour protein called Ki67 in the biopsy and in the tumour removed at surgery. Ki67 provides information on how rapidly the cancer grows. The reduction in Ki67 levels between the biopsy and surgery will be compared between the four groups. Vitamin D and melatonin are inexpensive with few side effects. If a reduction in cancer growth rate is shown then this would provide a strong reason for further large cancer prevention trials with Vitamin D and melatonin.
To compare the kinetics and efficacy of two functionally different diagnostic agents, Lymphoseek (CD206 receptor targeted) and 99mTc-Sulfur Colloid (SC) (Sulfur Colloid non-specific mapping agent) in intraoperative lymphatic mapping (ILM) and Sentinel Lymph Node Biopsy (SLNB).
Some breast cancer cells make a protein called Human Epidermal Growth factor receptor 2 (HER2). Patients with HER2 positive (HER2+) breast cancer receive medicine that attacks HER2, which helps these patients live longer. Some HER2 negative (HER2-) breast cancer patients also benefit from medicines that attack HER2, but we do not know why or which patients will benefit. This study uses a new imaging method, HER2-targeted PET/CT, to identify patients that may benefit from medicines that attack HER2. This is experimental.
This non-interventional prospective study will assess the safety of Herceptin SC (subcutaneous administration) as used in routine clinical practice. Patients with HER2-positive early breast cancer, naive and non-naive of HER2+ treatment who are to be treated in the neoadjuvant and adjuvant setting and scheduled to initiate a treatment with Herceptin SC in routine clinical practice use are eligible to participate. The total study duration is anticipated to be 38 months.
In this study, positron emission tomography (PET/CT) imaging will be used to evaluate sigma-2 (σ2) receptor activity in sites of primary breast cancer using the investigational radiotracer [18F]ISO-1.
Breast cancer is the most common cancer in many countries: in Italy about 48.000 new breast cancers are diagnosed every year and, despite improvements in diagnosis and therapy, about 13.000 women die every year for this disease . About 6-7% of breast cancer patients are metastatic at diagnosis , while the majority of patients with stage IV has a previous history of breast cancer that has already been treated. According to various prognostic factors (tumor size, lymph nodes involvement, grading, hormone receptors status, HER-2 status), in the worst-case scenario, more than 30% of node-negative breast cancer patients and more than 70% of node-positive patients relapse2. The evolution of metastatic breast cancer has changed considerably in the last years with the approval of new drugs. In fact, already in 2003 Giordano et al showed that the prognosis of metastatic breast cancer patients was improved significantly from 1970's to 2000 with a median survival of 15 months in the early 1970's compared with 60 months in the last 1990's. This significant survival gain was obtained with introduction of new drugs as hormonal, chemotherapeutic and biological agents. The greater availability of drugs has led to an increase in number of lines of treatment receiving by metastatic breast cancer patients. However, there are few published data on actual duration of metastatic breast cancer treatments. Moreover, there is no evidence to support a real impact on survival of treatments beyond the second-third line. Recently, a retrospective analysis of about 199 metastatic breast cancer patients treated with chemotherapy showed that tumor subtype is associated with the duration and number of lines of chemotherapy (for example HER positive versus "triple-negative" patients) .
For the specific patient population studied receiving 5-Fluorouracil, epirubicin and cyclophosphamide - Docetaxel sequence (cumulative dose <300 mg / m2), using a cryoprotection has never been assessed. The effectiveness of cryoprotection of onycholysis secondary to Docetaxel is not well established in this population (breast cancer in the adjuvant setting) and is based solely on a publication (Scotté) that does not contain the same therapeutic modalities (dose significantly higher). The few studies available have heterogeneous populations, nonrandomized, retrospective or with a small sample. By extension to what has been observed with higher cumulative doses of docetaxel, some teams offer mittens and booties chilled to their patients, a practice that is not the subject of a national consensus. The investigators wish to accurately assess the effectiveness of mittens and slippers chilled, their tolerance and their observance because of weak data on this specific population in the literature.
The role among metabolic syndrome and breast cancer risk is not well understood and must be further explored. The objective of this study is to evaluate the association between metabolic syndrome and breast cancer in Southern Brazil. In this case-control study, breast cancer patients and controls without malignant disease, matched for age (±5 years) and menopausal status, were interviewed and asked to make a glucose, HDL-cholesterol and triglycerides test. Waist circumference and blood pressure were measured using standardized procedures. Metabolic Syndrome was considered by NCEP ATP III (2001) and IDF (2006) definitions. Cases and controls were compared in relation to the presence of diagnosed MetS (yes/no), number of metabolic abnormalities identified (1 to 5) for each definition, and according to each metabolic abnormality cutoff point.
