Filter by:Recent pre-clinical studies strongly suggest that due to dysfunctional vasculature and blunted sympathetic constriction in the tumor, tumor blood flow is increased even by 200% compared to resting values. However, to the best of our knowledge these blood flow aspects have never been addressed clinically. Therefore, this research aims at investigating tumor blood flow response to exercise in human cancer patients. To address this goal, in total twenty (20) newly diagnosed breast cancer and eight (8) lymphoma patients will be recruited for the present acute exercise and tumor perfusion clinical trial. To study the effect of acute physical exercise on tumor blood flow and its heterogeneity, 30 minute bicycle exercise will be used to exercise these patients. Tumor blood flow will be measured by positron emission tomography at rest before and after the exercise. If the hypothesis of increased blood flow in response to exercise will be detected, this project has the potential to increase the basic physiological and mechanistic understanding of tumor microvasculature function in humans, which is also clinically highly relevant and can have long-lasting influences in the field in the future. Thus, the results from the project can be a breakthrough for cancer treatment, its mechanistic arguments, and thus renewal of evidence-based medicine and patient care.
The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics of the new formulation SHR-1316 in subjects with advanced tumors.
Upper Urinary Tract Urothelial Carcinomas are rare, aggressive tumors, accounting for 5 to 10% of all urothelial tumors. These include tumors which develop in the renal cavities (renal pelvis, calices) and ureteral tumors. Nephro-ureterectomy is the standard treatment but 80% of patients will have a relapse within 2 years. Only one trial has (Birtle et al. 2020), has shown the interest of postoperative chemotherapy. Neoadjuvant systemic treatment seems particularly interesting for a population which is going to undergo a nephronic loss and therefore reduction in kidney function which is likely to make patients ineligible for cisplatin. In favor of additional immunotherapy, it has been described that upper excretory tract tumors have a high immunogenic potential with a high rate of microsatellite instability. From surgical samples of patient tumors obtained after nephroureterectomy or biopsy material collected before treatment, we are going to generate patient-derived cell lines and xenograft models in the mouse. A recent publication has demonstrated the feasibility of this approach by specifying that the capture rate of tumor cells is 50% for patient-derived xenografts and 25% for patient-derived cells (Coleman et al. 2020). As tumors harvested from biopsies do not grow in patient-derived xenografts,we plan to graft the biopsies onto chorioallantoic chicken embryo membranes, a model which has never been used for this indication and which is one of the original features of our approach. These three concomitant approaches will allow us to increase our chances of obtaining stable upper urinary tract urothelial carcinoma lines to be used for the screening and identification of new treatments or new combinations of molecules that would benefit patients with upper urinary tract urothelial carcinomas, knowing that very few studies dedicated to this type of cancer have been conducted or published due to the rarity of the disease and the lack of existing models published on the subject of these particular tumors. .
This study will address medical devices manufactured by Biomet Microfixation (d.b.a. Zimmer Biomet) designed for fixation and stabilization of the facial and mandibular skeleton.
This is a post-market clinical follow-up study that use questionnaires such as Visual Analog Scale (VAS), the Neck Disability Index (NDI), or the Oswestry Disability Index (ODI) to compare the clinical improvement effects before and after surgery.
The purpose of this randomized controlled trial is to evaluate whether a trained community health worker (CHW) who engages with newly diagnosed patients after a diagnosis of cancer can effectively improve knowledge and receipt of evidence-based precision medicine cancer care services among low-income and minority patients.
The primary aim is to develop a software algorithm that has the capacity to detect the normal 18 anatomical structures of the lung by using the position of the scope during the bronchoscopy procedure and using existing bronchoscopy technology.
Cancer patients are considered vulnerable to COVID-19 infection. During the pandemic, cancer patients may need to continue their regular treatment of chemotherapy and / or radiotherapy and therefore must visit a hospital unit. As such, they may be at risk for SARS-CoV-2 infection by means of close contact to other patients and health care workers. Hospitals may implement policies to identify symptomatic subjects and limit their access to the chemotherapy / radiotherapy unit. However, asymptomatic COVID-19 positive patients may escape these filters and potentially be contagious to other patients and their health-related workers that care for other several patients. Therefore, there is a real risk of an outbreak that affects a particularly fragile patient population. Patients and their doctors need to know what is the risk associated to visiting a chemotherapy unit in order to decide if the risk outweighs the benefits of cancer treatment in their particular case. To date, this risk is unknown. The study will test patients and health care workers for COVID-19 infection during the peak of the pandemic in a chemotherapy unit in Mexico in order to determine this risk.
To evaluate the potential usefulness of 68Ga-BNU-PSMA positron emission tomography/computed tomography (PET/CT) for the diagnosis of primary and metastatic lesions in various types of cancer.
The neurotrophic protein S100B has been promoted as a neuromarker for decades, and to reflect the severity of brain injury. On the other hand, S100B is a tumor marker. The interpretation of its serum levels may be altered by a contribution from extracerebral sources and its renal elimination. In the present study we investigate the relevance of S100B as a prognostic factor, as well as the correlation with different CT classifications in a large cohort of patients with and without brain injury. Furthermore, we examine whether S100B is elevated in brain tumors.
