Filter by:The purpose of this study is to compare three types of radiation therapy for cancer that has spread to the spine. The two types of radiation therapy used in this trial are External Beam Radiation Therapy (EBRT) and Stereotactic Body Radiation Therapy (SBRT). EBRT delivers tightly targeted radiation beams from outside the body. SBRT is a specialized type of radiation therapy that allows high doses of radiation to small targets. This study will include standard dose SBRT and higher dose SBRT. Each participant will be randomly assigned to either EBRT, standard dose SBRT, or higher dose SBRT.
The goal of this observational study is to learn about the survival benefit of local therapy combination with target therapy in lung cancer brain metastases with EGFR mutation. The main questions it aims to answer are: - Is local therapy performed before or after target therapy would provide survival benefit ? - What kind of local therapy combining with target therapy would provide survival benefit, neurosurgical resection or radiotherapy?
The main purpose of this study is to learn more about the safety, side effects, and effectiveness of LOXO-435. LOXO-435 may be used to treat cancer of the cells that line the urinary system and other solid tumor cancers that have a change in a particular gene (known as the FGFR3 gene). Participation could last up to 30 months (2.5 years) and possibly longer if the disease does not get worse.
The goal of this clinical trial was to assess the diagnostic performance and safety of Sodium Fluoride F-18 Positron Emission Tomography / Computed Tomography (18F-NaF-PET/CT) in bone metastases of malignant tumors compared with Technetium[99mTc] Methylenediphosphonate Bone Scintigraphy ± Single Photon Emission Computed Tomography (99mTc-MDP-BS±SPECT). The enrolled subjects were randomly assigned to two sequences A and B at a ratio of 1:1. Within 7 days, 18F-NaF-PET/CT and 99mTc-MDP-BS±SPECT bone imaging were performed alternately. The sensitivity, specificity, positive and negative predictive value of 18F-NaF-PET/CT and 99mTc-MDP-BS±SPECT were calculated respectively based on the diagnostic data of standard of truth.
Current treatment for patients with secondary antibody deficiency (SAD) is Immunoglobulin replacement therapy (IGRT). There are currently no clinical guidelines for IGRT discontinuation in patients with SAD. This study will examine the IGRT discontinuation success rate and IGRT discontinuation rate in patients.
This study is investigating a new technique for delivering chemotherapy directly into the lungs at the time of surgery. Delivering chemotherapy directly to the lungs could potentially kill any microscopic cancer cells that are present in the lungs at the time of surgery, while sparing other major organs in the body from the side effects of chemotherapy. This technique is called In Vivo Lung Perfusion (IVLP). At the University Health Network, this IVLP technique has been used recently in a Phase I study in patients with sarcoma, and we are now expanding on that experience to include patients with colorectal metastases. The purpose of this study is to test the safety of the IVLP technique and find the dose that seems right in humans. Participants are given oxaliplatin into one lung via IVLP and are watched very closely to see what side effects they have and to make sure the side effects are not severe. If the side effects are not severe, then more participants are asked to join the study and are given a higher dose of oxaliplatin. Participants joining the study later on will get higher doses of oxaliplatin than participants who join earlier. This will continue until a dose is found that causes severe but temporary side effects. Doses higher than that will not be given. The other lung will not be infused with anything, so that we can limit unforeseen toxicity to a single lung and see if one lung does better than the other.
The goal of this observational study is to learn about treatments in brain metastases with poor prognostic factors. The main questions it aims to answer are: - What kind of local treatment provides a survival benefit for patients with poor prognostic factors? - What kind of systemic treatment provides a survival benefit for patients with poor prognostic factors? - Will the combination of local treatment and systemic treatment provide a survival benefit for patients with poor prognostic factors? Participants will be asked to provide personal information about their living status, symptoms, and disease control during the follow-up.
The goal of this observational study is to provide a feasible surgical strategy based on Nagata method for patients who require secondary revision surgeries and to verify its long-term aesthetic outcomes. The main question it aims to answer is: • Whether ear reconstruction surgery based on Nagata method can improve the unsatisfactory outcomes of primary reconstruction surgery? Participants who had accepted secondary ear reconstruction based on Nagata method in our department will be required to received questionnaires in the follow-up and their photographs will be collected for reconstructed ear evaluation of its realness through convolutional neural network (CNN) models we previously developed.
The goal of this phase 1 open label clinical trial is to evaluate the safety and preliminary efficacy of CodaLytic, an intratumorally-administered oncolytic virus, in patients with metastatic or otherwise inoperable breast cancer. The main questions it aims to answer are: - How safe is CodaLytic when administered in escalating dosing groups into targeted lesions? - What is the impact of CodaLytic on lesion response and disease progression? Eligible participants will be enrolled into four (4) escalating dose groups and treated with Codalytic through injection into a selected lesion(s) over twelve (12) weeks and then followed for up to one (1) year after the first dose. A safety committee will review the safety profile of each dosing group before the next dose-escalation. Study procedures will include physical examinations, injection site assessments, biopsies, imaging, and collection of blood/urine to assess safety, the body's immune response, and efficacy.
The objective of the present study is to determine the feasibility and to explore anti-tumor activity of intrathecal double immune checkpoint inhibition for patients with newly diagnosed leptomeningeal metastases from non-small cell lung cancer without driver mutation or melanoma.
