Active clinical trials for "Breast Neoplasms"

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.

This randomized phase II trial compared pathologic response rates (pCR) of early breast cancer following neoadjuvant fluorouracil-epirubicin-cyclophosphamide(FEC) and capecitabine-epirubicin-cyclophosphamide (XEC).

The purpose of this study is to compare the efficacy of a novel schedule of an oral anticancer drug, capecitabine, in patients with metastatic breast cancer. Mathematical models have predicted that 7 days of capecitabine followed by 7 days of rest is an optimal dosing schedule for this drug and previous studies done al Memorial Sloan Kettering Cancer Center support the tolerability of this scheme. This definitive, randomized trial comparing the efficacy of the new dosage with the conventional dosing schedule in patients with metastatic breast cancer is necessary and we hypothesize it will be superior in terms of efficacy. Dosing schedules based on mathematical predictions for optimal drug delivery based on efficacy rather than toxicity could facilitate more rapid and economical drug development. This trial is a proof of principle trial of the highest priority.

Most women with early breast cancer are treated with breast conserving therapy (BCT), consisting of breast conserving surgery (surgery to remove the cancer itself) followed by radiation to the breast. This treatment can take time and is associated with its own side effect profile. An innovative radiation technique called stereotactic body radiotherapy (SBRT) can deliver large doses of radiation precisely to the tumour while avoiding critical organs, therefore destroying the cancer and avoiding surgery altogether. SBRT has been successfully used for a number of cancers and it is proposed that it could be used to eradicate breast cancer. This feasibility study will investigate the feasibility and safety of treatment using SBRT in women with early stage breast cancer. Thirty-two women age 70 years or older with early breast cancer will be treated with SBRT (5 treatments) followed by breast conserving surgery and hormonal therapy. An MRI and breast conserving surgery will be performed at 8-12 weeks after radiation to assess response to treatment. The primary outcome of the study will be feasibility, meaning the ability to deliver radiation treatment as planned. Secondary outcomes will include treatment related toxicity and pathological response. If this study shows that SBRT can be used to treat patients primarily, it will lead to further evaluation of SBRT for early breast cancer.

Nimotuzumab is an IgG1 humanized monoclonal antibody that recognized an epitope located in the extra cellular domain of the human epidermal growth factor receptor (EGFR), inhibiting tyrosine kinase activation. This is a randomized, controlled, open-Label, multicenter, phase Ⅱ clinical trial of nimotuzumab plus Docetaxel and Capecitabine（TX）versus Docetaxel and Capecitabine（TX）as first-line treatment in patients with recurrent/metastatic triple negative breast cancer.

This 2 arms study will assess the efficacy and safety of the Vinorelbine-Docetaxel combination given as an initial upfront treatment (first line) to all metastatic breast cancer patients enrolled. Patients having a disease control following initial treatment, will be randomized to either oral Vinorelbine maintenance arm or Observation arm. The trial will also compare the efficacy and safety of maintenance oral Vinorelbine versus Observation.

The primary objective is to compare the phenotype and genotype of the primary tumor with those of its metastases in order to optimize the treatment of metastatic disease, in patients presenting with first metastatic progression of breast cancer.

The purpose of this study is to determine whether accelerated treatment with custom-made compression sleeve is more effective than standard procedure in the treatment of mild and moderate arm lymphedema secondary to primary cancer treatment.

Select the postmenopausal patients with breast cancer who is confirmed by core needle biopsy and at the clinical stage T2-4N0-2M0.Treat them with 4 cycles of TAC as neoadjuvant chemotherapy (Docetaxel was 75mg/m2, the EPI 60mg/m2 and the CTX 600mg/m2,21day/cycle).At the same time give daily oral exemestane 25mg for 12 weeks.Then assess the efficacy and safety of TAC and Exemestane.

Select 60 cases of women with breast cancer at clinical stage of T1-4N0-2M0. Then treat them with 4 cycles of TAC (Abraxane 260mg/m2,EPI 60 mg/m2 ,CTX 500 mg/m2, 21day/cycle) as neoadjuvant chemotherapy. Finally the investigators assess the efficacy and safety of Albumin-bound Paclitaxel.
