NCT06780059
Breast phyllodes tumors (PT) are rare fibroepithelial neoplasms originating from stromal tissue and account for less than 1% of all breast tumors. The World Health Organization (WHO) classifies PT into benign, borderline, and malignant subtypes based on pathological features such as mitotic activity, cellular atypia, tumor margin invasion, and stromal composition 1. The presence of malignant heterologous elements characterizes the tumor as malignant 2. Surgery is the primary treatment. However, even after R0 resection, borderline phyllodes tumors (BoPT) and malignant phyllodes tumors (MPT) patients remain face a high risk of local recurrence, with rates of 15%-20% and 25%-30%, respectively. Moreover, metastases occur almost merely in MPT, with a distant metastasis rate reaching 22%. Adjuvant radiotherapy has attracted attention for its potential to improve local control and reduce recurrence, but the role after R0 resection in PT patients remains unclear. Radiotherapy significantly reduces local recurrence rates in BoPT and MPT but shows no substantial benefit in benign cases. However, a meta-analysis by Yu et al. found that this effect is limited to MPT. Additionally, the effect of radiotherapy on survival rates in PT remains controversial. Most existing studies are retrospective and face limitations such as small sample sizes. The rarity of PT and conflicting evidence of impact of radiotherapy necessitate further study. While prospective trials are difficult due to limited cases, well-designed retrospective studies can offer valuable insights. In this study, the investigators also analyzed prognostic factors and identified subgroups to provide a clinical reference for the application of postoperative radiotherapy in BoPT and MPT patients.
NCT06172270
The goal of this study is to investigate breast cancer's internal heterogeneity and enhance diagnostic accuracy. The investigators aim to achieve this by utilizing Contrast-Enhanced Ultrasound (CEUS) technology, which provides detailed information about tumor perfusion dynamics. Traditional biopsy methods have limitations due to the invasive nature and complexity of breast cancer heterogeneity. Participants in this study will undergo preoperative breast cancer diagnosis using CEUS technology, which is safe, cost-effective, and convenient. Dynamic CEUS videos will be used to cluster perfusion characteristics at the pixel level within breast tumors, allowing the investigators to divide the tumors into distinct subregions based on these clusters. The investigators will then explore the correlation between these perfusion subregions and the diagnosis of benign or malignant breast tumors. The ultimate aim is to develop diagnostic models that utilize non-invasive imaging data to enhance breast cancer diagnosis. This approach reduces subjective judgments in the diagnostic process, potentially improving diagnostic accuracy. It also provides valuable information for personalized treatment decisions, thus advancing the field of breast cancer treatment.
NCT02004834
The purpose and the goal of this paper is to show whether the application of a combination of two local anesthetics, as opposed to the application of one local anesthetic at paravertebral block changes the hemodynamic variable. It is therefore a prospective randomized double- blind study, where we do a clinical trial in patients ASA(American Society of Anesthesiologists) 1 and 2 statuses between 18 and 80 years of age, using the ultrasound in plane technology.Upon arrival of patients in the unit for preparation procedures for anesthesia we set the ECG(electrocardiograph), noninvasive blood pressure, oxygen saturation, and arterial cannula in the radial artery After sterile washing of the dorsal surface, paravertebral space was identified with ultrasound using 8 Hz(hertz) linear transducer probe then needle position was confirmed with neurostimulation at the level of 2.0 - 5.0 mA(milliampere). When muscle contraction persisted at 0.4mA(milliampere), the anesthetic was applied in levels of Th 2, Th3, and Th 4 (7,0 milliliters per level). We applied the 0.5 % levobupivacaine and 2 % lidocaine, 7,0 milliliters of mixture per level in one group, while only 0.5 % levobupivacaine also 7,0 milliliters. by level in the second one. After that, the invasive hemodynamic monitoring was placed on patients and the induction with 1 % propofol 2-2.5 mg/kg.and Vecuronium 0,08 mg/kg. was performed with the application of supraglottic airway gel of appropriate size. The maintenance of anesthesia and sedation will be conducted with Propofol 1 % continuously ( 25-150 mcg / kg / min.)The measurements will be taken every 5 minutes during the first hour of the application of paravertebral block, then every 15 minutes during the second hour and if the operation takes more than two hours, the measurements are performed every 30 minutes. Postoperatively, invasive hemodynamic monitoring will be removed in post-anesthesia recovery room together with the arterial cannula and the patient will be sent to the hospital ward with non-invasive hemodynamic monitoring (blood pressure, pulse, saturation) until the termination of the blocks.Statistical methods, By comparing two target groups, we analysed the strength of the test with following assumptions: X2 difference test, the expected difference in variances in stroke volume between groups of 60%, α significance level of 0.05, and the minimum statistical test strength of 85%. The required total sample should include at least 80 patients, that is, 40 per group.Data will be presented in tables and graphs. Descriptive statistics of examined variables with appropriate measures of central tendency will be made. Smirnov -Kolmogorov test will assess the normality of data distribution. According to the received results, the appropriate parametric and / or nonparametric tests will be used. Comparisons of quantitative values between the two groups will be analyzed using the independent t-test or Mann-Whitney U test. Dependent values within each group will be analyzed using analysis of variance for repeated measures or Friedman test. Differences in categorical values will be analyzed by X2 test. The appropriate regression model will be made in order to predict the variability of stroke volume in which the dependent variable will be a variation of the stroke volume, while relevant clinical values will be taken as predictor variables. All P values smaller than 0.05 will be considered significant. This research is to present the main results - the existence of the significant change in Stroke Volume Variation (SVV) between groups using invasive hemodynamic monitoring, the changes of Stroke Volume Variation(SVV) depending on the time from the application within groups, differences in volume compensation of crystalloids and colloids and the need for the application of vasoactive drugs. Furthermore, as a secondary results we will present the time to maximal block development, the duration of post operative analgesia, patient satisfaction and time needed for the full recovery from the block.
NCT02187991
The goal of this clinical research study is to learn if the study drug, alisertib (MLN8237), in combination with chemotherapy (paclitaxel), can shrink or slow tumor growth in women with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative or HR-negative, HER2-negative (triple negative) locally recurrent or metastatic breast cancer (MBC). The safety of alisertib in combination with paclitaxel will also be studied. The physical state of the patient, symptoms, changes in the size of the tumor, and laboratory findings obtained while on-study will help the research team decide if alisertib plus paclitaxel is safe and effective in patients with this type of breast cancer. Alisertib belongs to a group of drugs called Aurora kinase inhibitors. Alisertib blocks the activity of Aurora A kinase, a protein that is involved in tumor cell multiplication and survival. Aurora A kinase is expressed at higher than normal levels in many types of cancer, including breast cancer, and preclinical studies suggest that blocking the activity of this protein can lead to the death of cancer cells. Paclitaxel is a chemotherapy drug commonly used to treat many different kinds of cancer, including metastatic breast cancer. The reason to combine alisertib and paclitaxel is that in cancer therapy, combinations of drugs are often more effective as a treatment than either of the same drugs used alone.
NCT06471673
This is an open-label Phase 1/2a study. Once the safety of the BC1 cell line alone has been demonstrated in Phase 1, in Phase 2, patients will be treated with the Bria-OTS regimen (see below) and a clinically available check point inhibitor (CPI). During the monotherapy phase of Phase 1, one patient will be treated intradermally every 2 weeks for 6 weeks (4 doses) with an initial dose of the BC1 cell line. If this dose is tolerated, the next patient will receive an increased dose of BC1. If once again tolerated, the third patient will receive a further dose increase of the BC1. Once at least 3 patients have been safely treated with the BC1 cell line, with no dose-limiting toxicity (DLT), the combinational phase of the study will commence. Following the monotherapy phase, patients will be treated with BC1 and the Bria-OTS regimen (see below) every 3 weeks, plus a CPI at the FDA approved labelled dose and schedule. There will be at least a 2-week spacing between enrollment of each of the first three subjects in the study in order to assess for any early unanticipated risk(s). During the Phase 1 combination and Phase 2 expansion phases, all patients will be treated with BC1 cells as part of the Bria-OTS regimen, which includes cyclophosphamide 300 mg/m2 2-3 days prior to BC1 cell inoculation, and peginterferon alpha-2a administered on the same day, following BC1 cell inoculation.
NCT00639171
Magnetic Resonance Spectroscopy (MRS) is a novel imaging technique for noninvasive probing of biochemical properties of tissue. While MRS does not generate images of tumor per se it allows biochemical spectroscopic data to be obtained in vivo from user defined region-of-interest. In this manner, biochemical information elucidated by MRS can be interpreted in relation to detailed anatomy and images of metabolite distribution can be created. The aim of MRS is to identify presence and concentration of metabolites characteristic for normal and abnormal (tumor) cellular activities hence allow differential normal tissue from pathological tissue, as well as allow differentiating malignant from benign tumors.
