Early gastric cancer is defined as gastric cancer that only invades mucosal or submucosal layer. The 5-year survival rate of gastric cancer can exceed 90% due to appropriate treatment. The most important consideration is whether there is lymph node metastasis. Preoperative examination including gastroscopy, endoscopic ultrasonography (EUS) and CT are not accurate enough to predict lymph node metastasis in early gastric cancer. In a retrospective study, we created a nomogram to predict lymph node metastasis in early gastric cancer. In prospective validation, the sensitivity and specificity of the nomogram was 75% and 91%, respectively. Sentinel lymph node is a promising concept in early gastric cancer. Using carbon nanoparticles as tracer, the sensitivity and specificity of sentinel lymph node predicting lymph node metastasis in early gastric cancer were 90% and 100%. Based on these results, we proposed a new method that combines the Nomogram and sentinel lymph node to predict lymph node metastasis in early gastric cancer. First, the probability of lymph node metastasis of early gastric cancer patients is calculated by the Nomogram. Those with low incidence of lymph node metastasis continue to the sentinel lymph node procedure. A patient will be considered non lymph node metastasis if his/her frozen pathology of the sentinel lymph nodes is negative during the surgery. Then the standard radical gastrectomy is performed with lymphadenectomy. By comparing postoperative pathology and sentinel lymph node frozen pathology, the specificity of Nomogram combining sentinel lymph node predicting lymph node metastasis in early gastric patients is calculated. The primary endpoint of this research is that the specificity of the above-mentioned method is over 95%.
The purpose of this study is to determine if the use of the Prevena™ System decreases the rate of subcutaneous seroma, superficial wound dehiscence and infection.
Metastatic vertebral disease is a major hazard for oncological patients because the performance and life quality will substantially deteriorate if presence of neoplastic compression. And the subsequent treatment and overall survival will be dismal. Restoration of vertebral stability and prevention of neurological deterioration are treatment goal. Surgical treatment is an important and effective method for metastatic spinal disease. For aggressive surgical method, long-term control is better. However, massive bleeding is often encountered in this surgery, and preoperative evaluation is very important for successful operation. Imaging play major role in this tasks. MRI, angiography, and nuclear medicine studies are common modalities, but take longer time and are often suboptimal. Dual-energy CT has the ability to detect contrast medium enhancement in osseous structure. It therefore is a potential optimal tool in the evaluate the metastatic spinal malignancy. It also own advantage of rapid scanning, optimal resolution, and easy reformatting.In this study, we intend to use this tool to establish the imaging biomarker for tumoural vascularity, to compare its performance with other modalities, and to investigate its optimal imaging condition, which will bring valuable information for treatment planning for aggressive spinal surgery before metastatic disease.
This phase I trial studies the side effects and best dose of edetate calcium disodium or succimer in treating patients with acute myeloid leukemia or myelodysplastic syndrome undergoing chemotherapy. Edetate calcium disodium or succimer may help to lower the level of metals found in the bone marrow and blood and may help to control the disease and/or improve response to chemotherapy.
To evaluate the safety and efficacy of treatment with SK-1403 for 52 weeks in patients with secondary hyperparathyroidism on maintenance hemodialysis.
Brain metastases (BM), occurring in 10-30% of adult cancer patients, are an important cause of morbidity and mortality.The prognosis of patients with BM is generally poor, with a median survival time of 2-6 months. Whole-brain radiation therapy (WBRT) has been advocated as the primary treatment for metastatic brain cancer. WBRT injures small cerebral vasculature and neuropil,effects linked to imaging-defined white matter changes. However, information on the neurocognitive function(NCF) impact of WBRT in BM patients is also limited.This study aims to explore and evaluate the impact of NCF in patients with multiple brain metastases receiving WBRT.
This study will evaluate the efficacy and safety of cobimetinib plus atezolizumab in participants with BRAFV600 wild-type melanoma with central nervous system (CNS) metastases and of cobimetinib plus atezolizumab and vemurafenib in BRAFV600 mutation-positive melanoma patients with CNS metastases.
This study compares two umbilical cord clamping times; the early one, up to a minute (ECC) and the late or delayed one, when the cord stop beating (DCC). The additional blood volume delivered to the newborn from the placenta - placental transference - by delaying umbilical cord ligation, increases the contribution of neonatal iron with increased iron stores in the infant, without increasing neonatal morbidity.
In general, brain metastases found after development of neurologic symptoms have poor prognosis. Therefore, the investigators aim to investigate whether regular brain MRI (Magnetic Resonance Imaging) can detect early brain metastases and influence survival through early brain management in HER2-positive and triple negative breast cancer.
