Prophylactic antibiotics like third-generation cephalosporin is recommended for acute gastroesophageal variceal bleeding (GVB). Endoscopic sequential therapy is an option in the secondary prevention of acute gastroesophageal variceal bleeding (GVB). However, the value of prophylactic antibiotics in the endoscopic secondary prevention of GVB is still unclear. It's assumed that the procedure of needle puncture under endoscopy will cause iatrogenic variceal bleeding. Besides, the surface of intraluminal varices is nonsterile, and injection of sclerosing agent or tissue adhesive will put patients at a risk of bacteremia. As a result, it's rational to use antibiotics prophylactically in the endoscopic sequential therapy of GVB. While giving antibotics in all patients might cause abuse of antibiotics. In clinical practice now, the prophylactic administration of antibiotics is quite subjective. We observe that quite a lot of cirrhotic patients had no infection after endoscopic secondary prevention for gastroesophageal variceal bleeding, even they have not been administed prophylactic antibiotics. In this non-inferiority trial, we are aimed to evaluate whether no value of prophylactic antibiotics will increase the postoperative infection or not, in the endoscopic secondary prevention of cirrhotic patients with gastroesophageal variceal bleeding.
Surgical lymph node dissection is the key to advanced gastric cancer. In recent years, after the overall implementation of standard D2 dissection, lymph node dissection for gastric cancer began to explore the direction of D1+ again. Current clinical studies of gastric cancer lymph node dissection based on intraoperative fluorescence navigation show that non-tumor specific lymph node fluorescence navigation surgery can only increase the total number of lymph nodes detected and ensure the completion of the dissection but not the accuracy. The sensitivity and specificity of the tracer metastatic lymph nodes are 56.3% (410/728), respectively. Specificity 46.1% (2669/5785). Tumor specific tracing of positive lymph nodes is the key to achieve accurate lymph node dissection for gastric cancer. Although tumor specific tracers are developing rapidly and related clinical studies are gradually being carried out, there are few reports on specific clinical studies on lymph node metastasis, suggesting that lymph node tracing is still a difficult problem. Previous basic studies have suggested that integrins play an important molecular biological role in the process of tumor lymph node metastasis. In the early stage, 99mTc3PRGD2 SPECT-CT showed good lymph node imaging effect in lung cancer and breast cancer, and 99mTc-oncoFAPI PET-CT also showed good lymph node imaging effect in gastric cancer. Therefore, this study aims to explore the application prospect of 99mTc3PRGD2 and other probes in molecular imaging of gastric cancer metastatic lymph nodes and guidance of lymph node dissection and tracer, so as to accumulate preliminary clinical data for exploring corresponding fluorescent probes for intraoperative tracer of gastric cancer lymph nodes.
The study is being conducted to evaluate the efficacy and safety of SHR6508 among Chinese patients with secondary hyperparathyroidism of chronic kidney disease treated by maintenance hemodialysis.
This phase I study aims to investigate the safety and efficacy of whole brain low dose radiotherapy (WB-LDRT) combined with ICI and intrathecal chemotherapy for treatment of refractory meningeal metastasis of lung cancer.
Treatment of stage IV esophageal cancer is traditionally palliative, but treatment response is usually poor. The role of surgery in the treatment of advanced esophageal cancer remains controversial. We sought to determine whether surgical treatment followed by neoadjuvant chemoradiation therapy might provide survival benefits for these patients. A retrospective review of esophageal cancer patients with M1 disease treated at National Taiwan University Hospital was performed from April 2002 to June 2021. Patient demographics and cancer staging, treatment, and disease recurrence, and time of follow up were included for analysis. Univariate and multivariate analysis was performed for overall survival and progression-free survival analysis. Propensity score matching based on patient age and tumor staging characteristics was also performed for analysis.
Some studies have shown that approximately 15% of patients with advanced hormone receptor (HR) positive breast cancer and 1/3 of triple negative breast cancer will develop brain metastasis. At present, there is no unified drug treatment standard for HER2-negative breast cancer brain metastasis (BCBM). The evidence of single traditional chemotherapy drug as the main treatment of brain metastasis is not sufficient. Some exploratory studies on HER2-negative BCBM have shown that the central nervous system objective response rate (CNS-ORR) of anti-angiogenic drugs combined with chemotherapy is around 55%-80%。 Adebrelimab (a humanized PD-L1 monoclonal antibody) specifically blocks the binding of PD-1 and PD-L1, terminates the immunosuppressive signal produced by T cells, and makes T cells re-recognize tumor cells and kill them, thereby inhibiting tumor growth. In China, Adebelizumab has been approved for using in combination with chemotherapy as a first-line treatment for extensive stage small cell lung cancer. Apatinib (a small molecule VEGFR tyrosine kinase inhibitor) mainly plays an anti-angiogenic effect in the treatment of malignant tumors by inhibiting VEGFR. Apatinib has been approved monotherapy for advanced gastric adenocarcinoma or gastroesophageal junction adenocarcinoma that has progressed or relapsed after at least two systematic chemotherapies, advanced liver cancer that has failed or is intolerable after at least first-line systematic treatment, and first-line treatment in patients with unresectable or metastatic hepatocellular carcinoma combined with camrelizumab. Due to the lack of effective drug therapy for HER2-negative BCBM, a variety of treatment combinations are still being explored. We hypothesized that adebrelimab plus apatinib and etoposide is an explorable and effective treatment for HER2- negative BCBM.
The goal of this project is to develop and validate a reproducible scorecard for the neurological assessment of patients with leptomeningeal metastases that can be used in clinical trials including such patients, as well as in clinical practice.
The purpose of this study is to determine whether cytoreduction of bulky metastatic disease using ultra high dose SBRT in combination with immunotherapy is tolerable and feasible In patients who have exhausted SoC treatment options.
Bone metastasis is a common disease of advanced tumors. It refers to the metastasis of malignant tumors originating in a certain organ to the bones through the blood circulation or lymphatic system. The incidence of bone metastasis in breast and prostate cancer is as high as 65%-75%. Bone metastasis of malignant tumors often leads to severe bone lesions, including bone pain, pathological fractures, spinal cord compression, hypercalcemia and other bone-related events (SRE). SRE caused by bone metastasis of tumors can greatly reduce the quality of life of tumor patients. In severe cases, it can lead to rapid deterioration of the condition or even death, which greatly affects the extension of the patient's survival period. ALMB-0168 is designed to activate Cx43 hemichannels, which release key anti-cancer factors (such as ATP) into the extracellular environment. In several mouse models of breast cancer bone metastasis and orthotopic osteosarcoma, ALMB-0168 dose-dependently inhibited tumor growth and was able to extend the lifespan of tumor-bearing animals, indicating its potential as a therapeutic drug for malignant bone tumors. . Clinical research data from China and Australia show that ALMB-0168 is safe and initially effective in patients with bone metastasis and osteosarcoma;
