Filter by: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 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.
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.
To evaluate the potential usefulness of 68Ga-DOTA/NOTA-FAPI-04 positron emission tomography/computed tomography (PET/CT) for the diagnosis of primary and metastatic lesions in various types of cancer.
To compare the efficacy and safety of megestrol acetate dispersible tablets combined with 5-HT3 receptor antagonist and dexamethasone triple antiemetic regimen and 5-HT3 receptor antagonist and dexamethasone combined antiemetic regimen in the control of CINV induced by hyperemetic chemotherapy.
The FURTHER study aims to evaluate the effectiveness and cost-effectiveness of MR-HIFU (alone or in combination with EBRT) compared to EBRT alone, the standard-of-care, as a palliative treatment option to relieve CIBP. The FURTHER study consists of a multicenter, three-armed randomized controlled trial (FURTHER RCT) and a patient registry arm (FURTHER Registry), which will be performed in six hospitals in four European countries.
Hyperspectral Imaging (HSI) is a contact free method to analyse the from the tissue reflected light in the range of 500-1000nm. Aim of the study is to identify special reflex patterns to identify special tissue
In this study, the characterization of human malignant glioma cell lines is described. After mechanical and enzymatic digestion of glioblastoma human biopsies from Neuromed IRCCS Neurosurgery patients, the investigators analyzed the established cell lines by immunohistochemistry. The investigators have already characterized 10 cell lines and results revealed that not all cell lines are positive for glial fibrillary acidic protein (GFAP), but only one was positive: the so-called COGI cell line. Moreover, the expression of Isocitrate Dehydrogenase 1(IDH1) and alpha thalassemia/mental retardation syndrome X-linked protein (ATRX) was investigated in all established cell lines. COGI cell line was also positive for IDH1R132 mutation and for ATRX. The results of characterization were summarized in table 1.
The Multi-OutcoMe EvaluatioN of radiation Therapy Using the Unity MR-Linac Study (MOMENTUM) is a multi-institutional, international registry facilitating evidenced based implementation of the Unity MR-Linac technology and further technical development of the MR-Linac system with the ultimate purpose to improve patients' survival, local, and regional tumor control and quality of life.
The aim of this study is to evaluate the effect of high-flow nasal cannula oxygen administration on maintenance of oxygenation and removal of carbon dioxide during apnoeic period in pediatric patients undergoing general anesthesia with rigid bronchoscopy
