Filter by:Bone metastasis causes bone destruction and skeletal related events (SRE) including compression fracture, hypercalcemia, and spinal cord compression. Therefore, palliative treatments for pain control and local control have become important and multidisciplinary multimodality approach is needed for treatment of bone metastasis. The efficacy of radiotherapy (RT) for bone metastasis is well known. And the results that bisphosphonate decreases SRE in patients with solid tumor and multiple myeloma reported. In previous retrospective reports, the combination of local RT and systemic bisphosphonate was more effective than RT alone. Therefore, Investigators designed a phase II study to evaluate the efficacy of RT in combination with zoledronic acid on pain relief and the safety of RT in bone metastasis patients with gastrointestinal tumors.
The main objective of our study is to determine if the evaluation of ingesta of cancer patients by VAS (on the day of hospitalization) is able to predict the actual ingesta of patients during hospitalization (for patients malnourished, at risk of malnutrition or risk free).
Endodrill is a new instrument for biopsy sampling in the GI-channel. The purpose of this study is as follows: - Compare EUS-guided Endodrill biopsies with endoscopic ultrasound guided fine needle aspiration (EUS-FNA) in terms of ability to establish the correct diagnosis of submucosal tumors in the upper GI tract.
This phase II clinical trial studies how well thermal ablation and spine stereotactic radiosurgery work in treating patients with cancer that has spread to the spine (spine metastases) and is at risk for compressing the spinal cord. Thermal ablation uses a laser to heat tumor tissue and helps to shrink the tumor by destroying tumor cells. Stereotactic radiosurgery delivers a large dose of radiation in a short time precisely to the tumor, sparing healthy surrounding tissue. Combining thermal ablation with stereotactic radiosurgery may be a better way to control cancer that has spread to the spine and is at risk for compressing the spinal cord.
The aim of the project is to study the role of minimally invasive imaging methods, such as magnification endoscopy with narrow-band imaging (M-NBI) combined with confocal laser endomicroscopy (CLE), in correlation with immunohistochemical analysis, for assessing the angiogenesis status of patients with gastrointestinal tumors, in particular with colorectal and gastric cancer. Angiogenesis, i.e. the process of forming new blood vessels, represents an essential event for tumor growth and metastasis and the importance of its understanding stems from potential applications for diagnosis, prognosis stratification and mainly from the possibility of developing and improving targeted therapies. While current methods for evaluating tumor vascularity are based on immunohistochemistry techniques with microvascular density (MVD) calculations, these imply repeated tissue sampling and are not feasible in the context of clinical practice. Imaging techniques might overcome limitations associated with MDV measuring, obtaining both functional and morphological information and enabling repeated evaluations that are necessary for the assessment of a dynamic process as angiogenesis during follow-up of targeted therapies. NBI is a digitally enhanced endoscopic imaging technique that uses optical filters to illuminate tissue with light at blue and green wavelengths. These are selectively absorbed by hemoglobin and, as a result superficial vascular networks are highlighted and morphological changes in capillary patterns can be described for different lesions. CLE represents a revolutionary technology that enables endoscopists to collect real-time in vivo histological images or "virtual biopsies" of the gastrointestinal mucosa during endoscopy, and has raised significant interest for the potential clinical applications and numerous research possibilities. After intravenous administration of fluorescein as a contrast agent, CLE enables real-time visualization of the tumor vasculature, which is structurally and functionally altered compared to the normal vascular networks. Therefore M-NBI will be used for enhanced visualization of morphological changes of the superficial capillaries, while CLE will be directed towards vascular regions of interest for characterization of these changes at the microscopic level. Furthermore, imaging studies will be backed by MVD calculation using immunohistochemical methods, based on tissue samples harvested during endoscopic procedures.
This phase I trial is to investigate the safety and the possible side effects of bi-specific antibody armed T-cell therapy when given together with low-dose IL-2 in treating patients with Her2-positive neoplasms of digestive system. Expanded autologues T cells that have been coated with bi-specific antibodies, such as anti-CD3 and anti-human epidermal growth factor receptor 2 (HER2), may stimulate the immune system in different ways and stop tumor cells from growing. Interleukin-2 may stimulate white blood cells to kill tumor cells.
This study evaluates the safety and efficacy of D-CIK immune cells combined with chemotherapy after resection of esophageal cancer
The purpose of this study is to see if an experimental drug, called copanlisib is effective and safe in treating adult participants with cholangiocarcinoma, when used in combination with gemcitabine and cisplatin.
Tenatumomab is a Sigma-Tau developed new anti-Tenascin antibody. It is a murine monoclonal antibody directed towards Tenascin-C. By means of this antibody, Tenascin-C expression was studied on a commercial tissue array slides each carrying malignant breast, colorectal, lung, ovarian or B and T cell Non-Hodgkin Limphoma tissue sections. All these cancers type showed positivity to Tenascin-C between the 64% and 13.3%. Consequently, Sigma-tau is exploring the use of the 131I-labeled Tenatumomab for anti-cancer radioimmunotherapy.
To assess the feasibility of a creative writing intervention in an advanced cancer population. Given it is a relatively simple intervention delivered by a non-clinician, the investigators are interested in better understanding its pattern of effect on patient psychological adjustment. The investigators aim to assess its feasibility in this study in order to inform a future larger study that will utilize a control arm.
