Filter by:The purpose of this study is to: 1) identify the palliative care needs of Emergency Department patients with advanced cancer, and determine if these needs can be rapidly assessed in the ED; 2) determine whether early palliative care consultation improves survival, quality of life and other burdensome symptoms and decreases utilization as compared to usual care.
The aim of the study is to evaluate whether tamoxifen at a low dose of 5mg/d reduces in the long term the incidence of invasive breast cancer and ductal carcinoma in situ, DCIS (DIN 1c, 2, 3) of the breast, in woman operated for lobular intraepithelial neoplasia (LIN1, 2 and 3) or ER-positive ductal intraepithelial neoplasia (DIN 1b, DIN2, DIN3, 1a excluded) of the breast. To improve the risk-benefit ratio, the use of lower doses of the drug has been proposed. Biomarker trials revealed that 5 mg/d was noninferior to 20 mg/d in inhibiting proliferation of breast cancer and normal endometrial tissue. By contrast, the risk of endometrial cancer si dose-dependent, and the dose reduction can lead a substantial decrease. Morover a dose of 5 mg/day is associated with an overall decrease of the estrogenic activity of tamoxifen on insulin like growth factor (IGF-I), sex hormone-binding globulin (SHBG) and antithrombin-III, with a decrease of venous thromboembolic events. Moreover, tamoxifen exhibits a high tissue distribution, so that a dose of 5 mg/day attains at the breast tissue level a concentration 10 times higher than that needed to inhibit cell growth in vitro. A prospective cohort study also showed that 10 mg on alternate days halves recurrence of DCIS in postmenopausal women. It has been shown that the treatment of dysplasia or pre-cancer drives the reduction of the invasive neoplasms onset. This is a chemoprevention trial designed to validatate the low-dose Tamoxifen in women with diseases at high evolutionary risk. The demonstration of efficacy and safety of such a treatment for the prevention of the invasive breast cancer would lead improvements in term of survival and quality of life for the patients at increased risk.
EUS-guided FNA has been proved to be a safe and useful method for tissue sampling of gastrointestinal track lesions and other organ lesions including mediastinal and intra-abdominal lymph nodes, pancreas and hepatobiliary tree. The usefulness of EUS-FNA depends on several factors. For example, experience of the endosonographers, adequate sampling, sample preparing, accurate interpretation by the cytopathologist and on-site cytopathology interpretation. However, in many hospitals, no cytopathologist can be present during EUS-FNA. Therefore, determining appropriate methods to obtain and prepare EUS-guided FNA are important to make correct a diagnosis without on-site cytopathologist. Suction with a self-retracting 10-mL syringe will likely bring in more cellularity but also more blood. Some endosonographers use no suction, others use constant suction. Usually specimen is expelled from a needle with pushing the stylet into the needle. But use of the stylet during EUS-FNA is difficult and time consuming process. Injecting air was not recommended, because of spraying out uncontrollably, increasing risk of air artifact and specimen clotting. However, there is no further study which one is the appropriate, suction or no suction and pushing the stylet or injecting air until now. The hypothesis and aim of the prospective randomized controlled trials are as follows: First hypothesis: There was no difference in the adequacy, cellularity, bloodiness, contamination, air artifact in specimen obtained by each methods, suction or no suction and pushing the stylet or injecting air. Aim #1 : To compare the adequacy, cellularity, bloodiness, contamination, air artifact in specimen obtained by each methods, suction or no suction and pushing the stylet or injecting air. Second hypothesis: There was no difference in sensitivity, specificity, diagnostic accuracy, positive predictive value, negative predictive value and statistical agreement in specimen obtained by each methods, suction or no suction and pushing the stylet or injecting air. Aim #2 : To compare the sensitivity, specificity, diagnostic accuracy, positive predictive value, negative predictive value and statistical agreement in specimen obtained by each methods, suction or no suction and pushing the stylet or injecting air.
The purpose of this study is to assess the safety, tolerability, pharmacokinetics and preliminary anti-tumour activity of ascending doses of AZD5363 under adaptable dosing schedules in Japanese patients with advanced solid malignancies.
The main purpose of this first human study with CC-115 is to assess the safety and action of a new class of experimental drug (dual DNA-PK and TOR kinase inhibitors) in patients with advanced tumors unresponsive to standard therapies and to determine the appropriate dose and tumor types for later-stage clinical trials. The bioavailability of tablet and capsule formulations under fasting and fed conditions will also be evaluated in some patients.
Radiosurgery is precisely delivered high dose radiation. It can be performed using multiple cobalt sources, a modified traditional gantry-based linear accelerator or a robotic linear accelerator. The treatment of brain metastases represents the most common indication for radiosurgery while new indications for this technology are continually being discovered. With the increasing importance of radiosurgery and the resource implications for radiotherapy programs the investigators have proposed the first direct technological comparison of robotic to linear accelerator radiosurgery for brain metastases.
RATIONALE: The identification of gene mutations in young patients with pleuropulmonary blastoma syndrome may allow doctors to better understand the genetic processes involved in the development of some types of cancer, and may also help doctors identify patients who are at risk for cancer. PURPOSE: This research study studies gene mutations in samples from young patients with pleuropulmonary blastoma syndrome at risk for developing cancer.
Background: - Gemcitabine and carboplatin are chemotherapy drugs used to treat several types of cancer, including cancer of the pancreas, bladder, ovaries, and lung. Lenalidomide, a drug that prevents the growth of new blood vessels in tumors, has been approved for treatment of certain blood cancers, but it has not yet been approved for use in combination with gemcitabine and carboplatin. Researchers are interested in determining the safest and most effective dose of this combined form of chemotherapy for solid tumors, particularly for urothelial cancer (tumors of the bladder, urethra, ureter, or renal pelvis). Objectives: - To evaluate the safety and effectiveness of combined lenalidomide, gemcitabine, and carboplatin as a treatment for solid tumor cancers. - To evaluate the safety and effectiveness of combined lenalidomide, gemcitabine, and carboplatin as a treatment for urothelial (bladder) cancer. Eligibility: - Individuals at least 18 years of age who have been diagnosed with solid tumors that have not responded to standard treatments. - Individuals at least 18 years of age who have been diagnosed with urothelial cancer that has not responded to standard treatments. Design: - Participants will be screened with a physical examination, medical history, blood tests, and tumor imaging studies. - Participants with urothelial cancer will receive lenalidomide alone for the first 14 days of a 21-day cycle before starting the first full treatment cycle. - All participants will receive gemcitabine on days 1 and 8, and carboplatin on day 1 only, of every 21-day treatment cycle. Lenalidomide will be taken daily at home for the first 14 days of each cycle. Participants will be asked to take aspirin or other medications to prevent the possibility of blood clots. - Participants may receive up to six cycles of treatment with this combination. If after six cycles the cancer has not grown or has shrunk, participants may continue to take lenalidomide alone for an additional 6 months (total of 12 months of therapy) or until the cancer recurs. - Participants will be monitored with blood samples, physical examinations, and tumor imaging studies through the cycles of treatment. - After the end of the last treatment cycle, participants will have followup visits every 3 months for the next 18 months, then every 6 months for another 18 months, and then yearly.
This is a multi- center, open-label, dose finding, Phase Ib study to be conducted in two stages: a dose escalation part to determine the maximum tolerated dose (MTD) safety and tolerability of concurrent administration of MEK162 and RAF265, followed by an expansion part to further assess the safety and preliminary anti-tumor efficacy of this oral combination within two separate patient populations: i) patients with advanced solid tumors harboring BRAFV600E mutations or ii) patients with advanced solid tumors harboring RAS mutations.
