Filter by:The purpose of this study is to learn whether our own made predictive algorithm can be used as a clinical practical decision support for patients with NSCLC spinal metastasis. The scoring system consists of the use of EGFR-TKI, KPS, Age, SCC, CA125 and smoking history. By predicting survival doctors could determine which patients are suitable for palliative therapy.
This study investigates the efficacy and the safety of Lanthanum Carbonate for the reduction of urinary oxalate excretion in patients with secondary hyperoxaluria and nephrolithiasis.
This study was undertaken to evaluate bone response in metastatic prostate cancer patients treated with Enzalutamide with or without Zoledronic Acid in combination with luteinizing hormone-releasing hormone (LHRH) analogue with the use of Whole Boby (WB) DW-MRI.
This study investigates the uptake of the radiopharmaceutical 68-GaNOTA-Anti-HER2 VHH1 in brain metastasis using PET/CT imaging. Patients with HER2-positive and HER2-negative cancer will be included and the uptake in their lesions will be compared. Optional 68-GaNOTA-Anti-HER2 VHH1 scans may be performed during or after treatment, at time points 12±6 weeks and 24±9 weeks after the first scan.
Upwards of 40% of cancer patients will develop brain metastases during their illness, most of which become symptomatic. The burden of brain metastases impacts the quality and length of survival. Thus the management of brain metastases is a significant health care problem. Standard treatment options include stereotactic radiosurgery and/or whole brain radiation. There is a great interest in studying the association between the functional characteristics of tumors - such as tumour hypoxia and lactate accumulation - and clinical outcomes in order to guide management. These characteristics may predict future tumor behavior and stratify risk of therapy failure. Hyperpolarized 13C MR imaging is a novel functional imaging technique that uses 13C-labeled molecules, such as pyruvate, and MRS to image in vivo tissue metabolism. There is significant clinical heterogeneity in patients with brain metastasis due to differences in underlying tumour biology. Biochemical differences in tumour metabolism have been shown to correlate with response to therapy. While the significance of tissue hypoxia for radiosensitivity has been established for years, the impact of lactate accumulation on radiosensitivity has only recently been recognized. Studies have shown that tissue lactate levels correlate with radioresistance in several human tumours. Hyperpolarized 13C pyruvate MRS has been shown in numerous pre-clinical studies and a recent clinical study to have great potential as a metabolic imaging tool. Our study seeks to establish the role of hyperpolarized 13C MRS in characterizing the metabolic features of intracranial metastasis. The results of this study will provide insight into intracranial metastatic disease signatures with MR spectroscopy and determine if there is added benefit for incorporation of this new technique into future clinical MRI protocols. If the technique can accurately differentiate between aggressive and indolent tumours based on MR spectroscopic patterns, hyperpolarized 13C MRS may have wide-ranging utility in the future. In the era of personalized medicine, the ability of imaging tests to predict response to therapy would open the door for individualized treatment options specific to each patient's disease biology.
The primary purpose of this study is to determine the non-inferiority of overall survival FOLFIRI with or without Bevacizumab compared with Irinotecan (CPT-11) with or without Bevacizumab as Second-line therapy in Patient with Metastatic Colorectal Cancer.
This is a single-center, open-label, single-arm, non-randomized study designed to evaluate PFS, safety, overall survival (OS), objective response rate (OPR), disease control rate (DCR) and biomarkers of cancer therapy based on Alphacait screening system in subjects with advanced malignant tumor.
This is a comparative study using resected/ biopsied tumors samples collected from renal cell carcinoma and urothelial carcinoma patients who underwent surgical removal of lesions, followed by immune checkpoint blockade (ICB) treatment targting programmed cell death 1 (PD1) but developed new lesions later were also removed and stored in the biosample repository (BSR). The histology and genomic analysis of the pre-treatment and metastatic samples from the same patient would be used to find out the changes that may have lead to metastasis. Also, metastatic samples from ICB naive patients would be collected and compared with those from ICB treated patients to find out if the metastasis in treated patients was due to development of reistance.
In the previous study, the investigator established a predictive model for non-sentinel lymph node involvement in early breast cancer (cT1-2cN0, 1-2 SLNs involvement). To validation the clinical value of the model, the investigator design a prospectively research using the model guiding for further axillary lymph node dissection in SLN-positve early breast cancer.
Primary lung cancer is one of the most common malignancies in China, with 57 percent of patients being diagnosed at advanced stage. At present, advanced lung cancer has entered the era of precise treatment. So it is very important to determine the gene mutation status of the tumor and prescribe drugs at the targets. Liquid biopsy is a suitable alternative when tumor tissues are difficult to obtain. Liquid biopsy technique refers to the use of human body fluid as a sample source to detect the information of related diseases, including blood, urine, saliva and cerebrospinal fluid. It is non-invasive, fast and simple, and can avoid the problem of insufficient sample size and support for repeated sampling to continuously monitor disease. With the increasing incidence of lung cancer and the development of diagnosis and treatment technology, the survival period of patients has been extended, and the incidence and diagnosis rate of the brain metastasis of lung cancer have increased year by year. The brain metastasis of lung cancer is the most common type of brain metastatic tumor. The incidence rate is about 40-50%, and the prognosis is poor——the natural median survival period is about 1-2 months. Because of the impractical intracranial tumor biopsy and very low level of DNA in peripheral blood, cerebrospinal fluid, which makes close contact with brain tumors, becomes potential available samples. Several studies have shown that genetic testing of cerebrospinal fluid is feasible. Therefore, this study aims to test the cerebrospinal fluid, blood and tissue by the latest second-generation sequencing technology at different time points, to dynamically monitor the gene mutation status of cerebrospinal fluid, blood and tissue, to explore the role of cerebrospinal fluid biopsy in the diagnosis and treatment of non-small cell lung cancer with brain metastases.
