Filter by:Oxaliplatin is a major antitumor agent but its use is limited by potentially disabling neurotoxicity, characterized by a sensitive defect in the extremities.Mangafodipir is a MRI contrast agent with antioxidant properties. Our previous laboratory works showed that mangafodipir is able to prevent hematologic toxicity of several chemotherapy agents, including oxaliplatin and to increase their antitumor activity. Preliminary clinical data suggested that mangafodipir could prevent oxaliplatin neurotoxicity.The primary purpose of the present study is to assess the protective effect of mangafodipir in patients who have a already moderate oxaliplatin neuropathy and in whom the continuation of this treatment is desirable because of significant antitumor effect.
Different pathophysiologic mechanisms are responsible for the development of chronic pain disorders. Pain pathways are triggered in part by ectopic discharges of voltage-sensitive sodium channels, which are in abundance in both the peripheral and the central nervous systems. Tetrodotoxin (TTX) is a selective blocker of Na+ channels and causes analgesia either by decreasing the propagation of action potentials by Na+ channels and/or by blocking of ectopic discharges associated with chronic pain. TTX is extracted from the puffer fish (fugu). Results from animal pharmacology studies revealed that TTX is a more potent analgesic than standard analgesic agents such as aspirin, morphine or meperidine. At present, the management of severe cancer pain generally includes the use of opiates. This can often result in undesirable side effects, and treatment with this type of medication is not always effective. Because currently available pain-relieving therapy is unsatisfactory for many patients, there is a need for new therapeutic approaches for the management of moderate or severe cancer pain. Recent studies indicate that intramuscular (into a muscle) or subcutaneous (under the skin) injections of tetrodotoxin (TTX) may reduce pain in cancer patients who did not respond to standard therapies. The current proposed study (TEC-006OL) is designed to provide the option for all patients who participated in the TEC-006 study (both tetrodotoxin and placebo-treated) to receive or continue to receive tetrodotoxin treatment.

The current proposed study (TEC-006) is designed to 1) demonstrate in a double-blind, placebo-controlled trial that the subcutaneous 30 μg b.i.d. dose of TTX for 4 days is effective in reducing pain outcome and improving quality of life; 2) characterize the onset and duration of analgesia, and 3) demonstrate that TTX is well tolerated in patients with inadequately controlled cancer-related pain.
The PACT Study (Physical Activity after Cancer Treatment) is a unique study within the field of cancer rehabilitation in Denmark. It differs from other studies mainly due to the intervention itself. A combination of physiological, health educational and therapeutic elements will be tested. These components are incorporated into a one-year training program for mixed groups (i.e. men + women, with varying cancer diagnoses) to encourage them to enhance their well.-being and quality of life. The overall aim of this approach is to place increased focus on the treated cancer patient's introduction to and exploitation of both physiological and psychosocial yields through physical exercise. Whether or not the study results bear a positive effect, they are expected to support new knowledge in rehabilitation for cancer survivors.
The purpose of the study is to determine the Pharmacokinetics of Low Molecular Weight Heparin (LMWH) in Cancer patients, and compare it to the Pharmacokinetics of LMWH in Patients without cancer. We also intend to detect any correlation between heparanase blood and urine levels and the Pharmacokinetics of LMWH.
The purpose of this study is to determine whether an Internet-based program, Sleep Healthy Using the Internet (SHUTi, or "Shut-Eye"), can help to improve the sleep of people who are in remission from cancer and experiencing symptoms of insomnia.
Cancer patients often experience multiple physical, functional and psychosocial symptoms, but have limited support while being at home between treatments and during rehabilitation. WebChoice is a novel Internet support system that extends traditional health services into patients' homes. The system allows patients to monitor symptoms over time, and provides access to evidence-based self-management options tailored to their reported symptoms as well as a communication area where patients can ask questions to a clinical nurse specialist in cancer care and exchange experiences with other cancer patients. This randomized clinical trial: 1. Tests the effects of WebChoice on primary outcomes of symptom distress, quality of life, depression and health service use, and secondary outcomes of self-efficacy, social support . We will also analyze: 2. Relationships between primary and secondary outcomes; 3. How patients' symptom distress varies over time; 4. Patients' preferences for participation in decision making about symptom management 5. How patients use WebChoice, such as frequency of use, duration, most used components; 6. How patients' experience WebChoice's usefulness and ease of use; 7. Patterns and content of patients' communication with the cancer nurse and other patients. 325 cancer patients (189 breast cancer and 136 prostate cancer patients) were recruited from throughout Norway through advertisements and invitation letters and the Norwegian Cancer Registry. Patients were randomly assigned to WebChoice or the control group that received usual care. Patients are being followed with 5 repeated measures over 12 months. Data are being collected through questionnaires, from system logs, and from interviews that were conducted in subset of experimental group patients. The primary hypothesis will be tested with Repeated Measures ANCOVA techniques. The other research questions will be answered using various inferential and descriptive techniques and through content analysis of messages and transcripts of patient interviews. This study can make a significant contribution to reduce unnecessary suffering and improve the quality of life for a large group of cancer patients.
Patient-provider shared decision making and the inclusion of patients' illness experiences and preferences in patient care are prioritized areas in health care. CHOICE is a computer-based support system for patient-centered symptom management of cancer patients developed for this purpose. In this randomized clinical trial at Rikshospitalet- Radiumhospitalet HF 145 adult stem-cell transplantation and newly diagnosed lymphoma and leukemia patients used CHOICE for assessments of their symptoms, problems and priorities for care at in-and outpatient visits during treatment and rehabilitation. In the experimental group this information was shared with physicians an nurses for subsequent care planning, but not in the control group. This study tested effects of CHOICE on symptom- related patient care and outcomes of symptom relief, patients' needs for care over time and patient satisfaction;(2) analyzed how patients' symptoms, needs for care varied during illness/treatment stages; and (3) evaluated CHOICE' ease of use and user satisfaction. Controlling for gender, age, diagnosis, and type/stage of treatment, education, depression, health related quality of life, and social support, repeated measurement models were used to test differences and variations in outcome variables within and between groups and over time.
This exploratory clinical study is designed to obtain pre-therapeutic imaging assessments using positron emission tomography (PET) imaging in 21 patients with Stage IIIB/IV or recurrent non-small cell lung cancer (NSCLC) and an early post therapy assessment at baseline and at various early time points (2 weeks in 7 patients, 4 weeks in 7 patients, and 6 weeks in 7 patients) after institution of erlotinib (anti-EGFR) (Tarceva) and bevacizumab (anti-VEGF) (Avastin) for first-line treatment of Stage IIIB/IV or recurrent non-squamous NSCLC. The proposed PET imaging and blood derived biomarkers trial is a companion study to an approved therapeutic trial (IRB# 24377). The therapeutic trial of erlotinib (Tarceva) and bevacizumab (Avastin) for first-line treatment of Stage IIIB/IV or recurrent lung cancer with drug costs exceeding $150,000 per patient/year (study drug budget exceeds $5 million) was funded for study at the HCI and the HICCP, statewide trial network. The proposed imaging study has been funded by the University of Utah Synergy Grant Program. The clinical imaging biomarkers will include an assessment of tumor metabolism [Banrasch 1986, Frauwirth 2002, Garber 2006, Kelloff 2005, Pauwels 1998, Semenza 2001, Smith 1999, Smith 2000, Sokoloff 1977, Warburg 1956, Weber 1977A, Weber] (dynamic FDG-PET); tumor proliferation [Rasey 2002,Shields 2001,Shields 1998, Vesselle 2002, Schwartz 2003] (dynamic FLT-PET); tumor blood flow and perfusion( H215O-PET)[Lodge 2000]; and tumor blood volume of distribution ( H215O -PET)[Lodge 2000] in the same patient at baseline and then in the same patient at one of the post therapy time points (2 weeks, 4 weeks, or 6 weeks). The investigators hypothesize that by using a set of imaging derived biomarkers and biomarkers from blood they can predict response, either prior to or at an earlier time point than would normally be determined with standard imaging techniques, in patients with lung cancer receiving combined bevacizumab and erlotinib.
Patients must have had their breast cancer treated at the Huntsman Cancer Institute to be eligible for this trial. OBJECTIVES: To use quantitative FDG-positron emission tomography (PET), functional MRI (fMRI) and co-registered anatomic MRI imaging to better understand the cognitive disorder known as "chemobrain" which effects up to 16 -50% of individuals receiving long-term adjuvant chemotherapy [Tannock 2004, Matsuda 2005]. The study is exploratory to obtain proof of feasibility pilot data to support an eventual submission to the NIH. Neuropsychological Testing A battery of testing will be used to assess the subjective complaints of cognitive impairment in the symptomatic patient cohort. Similarly the same battery of tests will be used to assure that the non-symptomatic patient control group and the age-matched normal controls do not exhibit any cognitive impairment. The following set of clinical tests will be performed to assess the degree of cognitive impairment in all subjects.
