Filter by:The immune response against tumors can be highly effective in preventing tumor development, growth and metastasis under certain circumstances. However, tumor associated immune suppression can profoundly limit the impact of natural tumor immunity and also reduce the effectiveness of tumor immunotherapy strategies. A major component of tumor associated immune suppression is mediated by myeloid cells, especially the monocytic subset of myeloid derived suppressor cells (MDSC). In recent studies that were conducted through a CCSRI Innovation grant, the investigators discovered that oral treatment of mice with the commonly used histamine receptor 2 (H2) antagonists ranitidine or famotidine inhibits both primary breast tumor development and metastasis, in three distinct mouse tumor models and reduces the numbers of monocytic MDSC. These findings have enormous potential to aid in effective cancer immunotherapy and may have immediate implications for cancer patients. The objective of this investigation is to determine whether treatment with the H2 receptor antagonist ranitidine alters immune suppression, through modulation of immune cell populations. The investigators will examine peripheral blood monocyte, neutrophil and NK cell numbers, subsets and activation status from healthy volunteers treated for 6 weeks with daily oral ranitidine. Ranitidine is widely available and used over the counter in Canada. These drugs are widely recognized as safe, well tolerated and have very few side effects. It has been suggested that among the general population, over 10% of those over the age of 65 take such medications on a regular basis for relief against gastrointestinal discomfort. The outcome of pre-clinical studies in mice warrant further investigation into transferability to humans. If the outcome of the current proposal proves to be viable, then these drugs could provide a safe method to reduce tumor associated immunosuppression with broad implications, both for current cancer patients and for those at high risk of developing cancer. Further to this, the outcome of our proposal may provide a new strategy for improving the effectiveness of T-cell mediated immunotherapy.
Cancer is the most important acquired risk factor of thromboembolisms. More than 20% of all episodes of venous thromboembolism (VT) or pulmonary thromboembolisms (PT) are cancer related. Cancer patients with VT or PT are treated with low molecular weight heparins (LMWH) during at least 3 months, but nowadays the duration of treatment is not accurately determined. The D-Dimer determination has been used like recurrence predictors after LMWH treatment suspension, but in cancer patients the useful is limited. Phospholipid-dependent microparticles could been used like recurrence predictors in cancer patients and tailored the duration of LMWH treatment for each patient.
This study tested the effects of emotion regulation strategies (reappraisal, reassurance, and empathy) on pain responses in children with cancer. Children with cancer were randomly assigned to one emotion regulation strategy during an experimental pain task (the cold pressor task [CPT]). During the CPT, children rated their pain and provided saliva samples immediately before, after, and then 15 minutes after the CPT. This study examined the influence of emotion regulation on self-reported pain and physiological activity assessed through saliva samples.
Phase 1 study evaluating the safety and tolerability of YS-ON-001 in patients with advanced solid tumors who have limited available treatment options, and exploratory evaluation of the pharmacological effect and efficacy of YS-ON-001. The study will be conducted in two parts: dose escalation and cohort expansion
The aim of this study is to examine whether self-monitoring PA with the RunKeeper app with additional physiotherapy coaching is superior in improving patients' self-reported leisure-time PA compared with usual care in cancer patients after 12 weeks. This is a single-center, prospective, two-armed, randomized controlled trial. Adult cancer patients and cancer survivors are randomized in one of the two study arms, (Group A) RunKeeper app + physiotherapy coaching or (Group B) usual care. Patients assigned to the intervention group will be instructed to use the RunKeeper app for 12 weeks to self-monitor leisure-time PA. In addition, patients will be educated about the health risks of a sedentary lifestyle, inactivity and (when applicable) other unhealthy lifestyle behaviors (e.g. unhealthy diet, overweight or obesity, sun exposure, alcohol intake). Benefits of a behavior change, becoming physically active and pursuing a healthy lifestyle will be explained by a trained physiotherapist who will also coach the patient during the PA program. The biweekly physiotherapy coaching starts at baseline and will follow a structured sequence of strategies to change patients PA behavior which will contribute to the adoption of leisure-time PA in patients daily living, so the program will be optimally tailored to the patients capabilities and preferences. The primary endpoint is to examine the effectiveness of the RunKeeper use with additional physiotherapy coaching in improving patients' leisure-time PA compared with usual care in cancer patients as measured by the PASE subscale leisure-time Sum Score at baseline, 6, 12 and 26 weeks.
Evaluation of the efficacy of the combination of olaparib and trabectedin in adult patients with locally advanced/metastatic solid tumors that failed standard treatment and whose molecular sequencing tumor profiles show homologous recombination repair (HRR) defects. The primary objective is to show superior disease control rate in patients with HRR-deficient tumors treated with olaparib and trabectedin compared to treatment according to current guidelines (physician's choice). This trial aims to establish whether the PARP-dependency of HRR-deficient tumors across entities can be exploited for therapeutic benefit.
This study is a Phase 1-2 open-label dose escalation study of the immuno-activating monoclonal antibody APX005M administered in combination with nivolumab to adult subjects with non-small cell lung cancer or metastatic melanoma. The Phase 1 portion is intended to establish the maximum tolerated dose and the recommended phase 2 dose of APX005M when administered in combination with nivolumab. The Phase 2 portion of the study will evaluate safety and efficacy of the combination.
Fatigue is a troublesome symptom for breast cancer patients, which might be mitigated with exercise. Cancer patients often prefer their oncologist recommend an exercise program, yet a recommendation alone may not be enough to change behavior. Our study will determine whether adding an exercise DVD to an oncologist's recommendation to exercise led to better outcomes than a recommendation alone.
The goal of this study is to reduce preference sensitive, unnecessary daily imaging during radiation treatment in which a pre-planned quality improvement default option for radiation treatment prescriptions will be introduced throughout the network of Penn Radiation Oncology.
This is a Phase I evaluation to determine the usefulness of a new brachytherapy device that utilizes active components (Palladium-103) of standard devices in a novel configuration. This study may benefit resectable pancreatic cancer patients by reducing the radiation dose to adjacent critical structures, while giving a therapeutic dose to diseased tissue, such as at a surgical margin.
