Filter by:This study is looking at whether patients with cancer that has aggressively spread to the spine can be treated with stereotactic body radiation therapy only and avoid a large spine surgery
The goal of this clinical trial is to use new imaging methods to help in finding out whether the imaging shows that there is a tumor in people with a brain metastasis. The main question it aims to answer is whether positron emission tomography (PET) and magnetic resonance imaging (MRI) find cancerous tissue better than other types of imagining. Participants will undergo a single PET/MRI scan, followed by a separate MRI scan with a tracer. Study participation will last about 3 hours.
This is a two-stage trial consisting of a Part I, dose escalation and dose-finding component to establish the Maximal Tolerated Dose (MTD), if any, and Recommended Part 2 Dose (RP2D) of XON7, followed by a Part II component to investigate anti-tumors efficacy in selected solid tumor types and to further evaluate safety and tolerability of XON7 at RP2D.
This study intends to conduct a small, prospective, single-center clinical study to explore and evaluate the efficacy and safety of pyrrotinib combined with capecitabine and bevacizumab in HER2-positive advanced breast cancer with brain metastases.The overall objective is to provide a new drug regimen for HER2 positive breast cancer patients with brain metastases by balancing survival benefits and patient quality of life.
OLIGAMI trial is a multi-institutional, two-arm, open-label, randomized controlled phase III trial being conducted with the participation of 50 hospitals belonging to Japan Clinical Oncology Group. After the first registration, all patients will be performed in a 12-week, subtype-specific, systemic therapy consisting of CDK4/6 inhibitors with hormonal therapy for luminal BC, docetaxel with trastuzumab and pertuzumab for HER2-positive BC, chemotherapy with immune checkpoint inhibitors for triple-negativeBC expressing PD-L1, and olaparib for cases harboring BRCA mutations. For other triple-negative BC, chemotherapy will be administered. If this 12-week systemic therapy does not cause any progression or complete response, patients proceed to second registration for randomization; arm A continues same systemic therapy alone, and arm B performs MDT followed by same systemic therapy. The MDT will involve either RT or surgery, and RT will involve mainly SBRT and partly conventional RT.
The goal of this observational study is to learn about the the pattern of metastasis of the No.253 lymph node in colorectal cancer. The main questions it aims to answer are: 1. What are the risk factors for metastasis to the No.253 lymph node? 2.What is the prognosis for patients with metastasis to the No.253 lymph node? Patients with descending colon cancer, sigmoid colon cancer, and rectal cancer who undergo curative surgery with dissection of the No.253 lymph node are included in this study
The purpose of this study is to find out whether the combination of cabozantinib, nivolumab, and radiation therapy is a safe and effective treatment that causes few or mild side effects in people with renal cell cancer that has spread to the brain. The researches will also look at how the study treatment affects the quality of life of participants. They will measure the quality of life by having participants complete questionnaires.
This project intends to select cases that meet the research requirements, take secondary hyperparathyroidism, primary hyperparathyroidism and normal human parathyroid tissue, a total of three groups, 4 cases in each group, through the method of single-cell transcription and sequencing, construct a map of human parathyroid function types, reveal the gene structure and gene expression status of cells, and visualize the expression characteristics, intercellular heterogeneity, and heterogeneity of cell subsets of secondary hyperparathyroid cells in a hierarchical manner, draw a single-cell map, and compare the differences between groups. To explore the pathogenesis of secondary hyperparathyroidism. Secondary hyperparathyroidism, parathyroid tissue of primary hyperparathyroidism and normal parathyroid tissue obtained by accident were collected, frozen and preserved, frozen tissue thawed, single-cell suspension was prepared and each cell was specifically labeled by the Mozhuo Genomics system, after oil breaking, polymerase chain reaction amplification, reverse transcription to obtain complementary DNA, and a library of complementary DNA that passed quality inspection was constructed to obtain high-quality data of parathyroid cells. Cell Ranger, R Seurat package, and t-SNE dimensionality reduction diagram were used to reduce the dimensionality, cluster, and visualize the data. In order to construct a single-cell atlas of parathyroid glands, investigators performed cluster analysis of similar cells according to the gene expression profile, and then visualized the data by t-SNE. According to the results of cell clustering, the specific and highly expressed genes in each cell cluster were identified. Cell populations were identified according to the expression of landmark genes, and the differences in cell types and proportions between groups were compared.
The researchers are doing this study to see if one session of high-dose contrast-enhanced MRI-guided SBRT (stereotactic body radiation therapy) is effective for colorectal cancer that has spread to the liver. The researchers will evaluate how well the study treatment can prevent the liver metastasis from growing and spreading. In addition, they will see whether it causes any side effects and whether there are any characteristics of the research MRI images that can predict response to treatment.
The primary objective of this interventional study is determine if the future liver remnant can be optimized by improving liver function pre-operatively in patients who are scheduled for major hepatectomy. The main questions it aims to answer are: 1. Does high-dose insulin therapy improve liver function in the pre-operative setting? 2. What is the effect of high-dose insulin therapy on liver function and liver regeneration after a liver venous deprivation (LVD) procedure? 3. What is the relationship between volume hypertrophy and function in the regenerating liver? Participants will receive a 6-hour infusion of insulin and dextrose to maintain a hyperinsulinemic-normoglycemic state in the weeks prior to planned liver surgery to assess its effect on liver function measured by 99m-Tc-Mebrofenin hepatobiliary scintigraphy.
