Filter by:In the last 10 years, the treatment of metastatic cutaneous melanoma has changed dramatically. The new systemic treatment with immunotherapy has led to a dramatic improvement in quality of life and overall survival. Systemic treatment means that the patient receives the drug as an infusion into a vein. Unfortunately, we know that immunotherapy is not equally successful in all patients. Recent studies have shown that the success of the treatment is not only influenced by the cellular composition of the metastasis, but also by its surroundings. This is called tumor microenvironment. Depending on the differences in the composition of this microenvironment, some metastases can be described as immunologically hot and others as immunologically cold. Immunologically hot metastases respond better to immunotherapy than immunologically cold metastases. Studies have shown that with some interventions we can change the tumor microenvironment from being immune-cold to being immune-hot. Electrochemotherapy is one of the interventions that might improve the efficacy of immunotherapy in cutaneous melanoma. Electrochemotherapy is an established method for the local treatment of tumors, in which only a certain tumor is treated with special electrodes, to which a weak electric current is applied. We hypothesize that electrochemotherapy stimulates the body's own immune response and enables more effective treatment. Since immunotherapy also stimulates the body's own immune response to cutaneous melanoma cells, the interaction of the two drugs could be even more successful. Recent research results support this assumption. The primary objective is to evaluate the changes in the tumor microenvironment of cutaneous and subcutaneous melanoma metastases induced by electrochemotherapy, based on the histologic analysis of treated and untreated metastases before and after treatment. The secondary aim is to determine whether the changes in the tumor microenvironment differ depending on the chemotherapeutic agent used. The results will help us to better understand the synergistic effects of electrochemotherapy and immunotherapy on cutaneous melanoma metastases. The combination of systemic immunotherapy and electrochemotherapy could become an important treatment method for patients with metastatic melanoma.
The goal of this clinical trial is to compare in newly diagnosed patients with resectable rectal cancer with lateral lymph node metastasis. This study aims to - further verify the safety and efficacy of FOLFOXIRI three-drug regimen - Using multiple omics techniques to identify and confirm specific molecular markers Participants will be treated with FOLFOXIRI three-drug combination regimen. Researchers will compare another group treated with conventional preoperative chemoradiotherapy to see if the experimental group is superior to the control group in terms of 3-year disease free survival, local recurrence rate, lateral lymph node positivity rate, and 5-year overall survival rate.
The goal of this clinical trial is to evaluate the clinical efficacy and safety of Furmonertinib in EGFR mutated NSCLC patients with leptomeningeal metastasis and to explore the feasibility of CSF ctDNA detection for efficacy evaluation. Participants will be treated with 160mg Furmonertinib daily and tumor evaluation will be performed every 6-8 weeks. The participants' blood and cerebrospinal fluid samples will be collected three times during the study for ctDNA detection.
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 aim of this randomized study is to investigate local tumor control,survival outcomes and complications on patients of liver metastasis in small cell lung cancer.
Immunity of cancer patients is an important issue. According to cancer immunity, it can be divided into three phases: clearance phase, equilibrium phase, and escape phase (cancer cells can avoid the recognition of immune cells). Βeta-glucans is extracted from yeast, it can increase immune function and drive of hematopoietic stem cells in animals and clinical trials. Glutamine can increase the repair of oral and intestinal mucosa of patients receiving chemical and radiation therapy and can increase the lymphocytes of patients. Colostrum contains IgA, IgG, IgM, etc., known to protect the baby Cancer patients who are infected with intestinal bacteria and undergo systemic chemotherapy are less immune than normal adults. Investigators will compare β-glucan, glutamine, and colostrum immunoglobulin powder with β-glucan and control group, each group has 30 people, and observe the side effects and blood of patients under standard chemotherapy. The performance of the immune system, such as helpers and cytotoxic T cells and NK cells, and to observe the differences in treatment interruption or delay rates and treatment rates.
Luminal type A breast cancer is a type with good clinical prognosis, and the proportion of lymph node metastasis is low, but a small number of patients have more lymph node metastasis when the primary tumor is very small, and the survival is poor, suggesting that this part of Luminal A breast cancer has the different expression of some genes from that of general Luminal A breast cancer, which affects tumor invasion and participates in the occurrence of tumor metastasis. But the mechanism is not clear, especially in the current tumor microenvironment and immune related mechanisms.We want to investigated the relationship of the transcriptional tumor immune microenvironment with early lymph node metastasis among Luminal A type breast cancer.
Clinical results on intra-arterial adjuvant chemotherapy for prevention of liver metastasis following curative resection of pancreatic cancer
More than 4200 new cases of colorectal cancer (CRC) are diagnosed each year in Denmark, and 30.000 patients live with the diagnosis. Up to 40% of CRC patients will have synchronous liver metastases (LM) at the time of the diagnosis or will develop metachronous LM during the course of their disease. CRC-LM are treated with a combination of chemotherapy and liver surgery, but less than 25% of the referred patients with CRC-LM may be treated with curative intend. If looking at population-based data this figure drops to less than 5%. During pre-operative chemotherapy the treatment response is monitored by CT and MR scans, and the patients are then discussed on multidisciplinary team (MDT) conferences. However, monitoring is inaccurate since the simple measurement of size of the liver lesions cannot provide reliable evidence of the treatment response. The cancer cells may actually have been replaced by scar tissue but without any shrinkage. The question is how may we improve the evaluation of treatment response? With the goal of improving the assessment of the response to chemotherapy, and thereby only treat the patients that will benefit from chemotherapy?
The purpose of the study is to evaluate the long-term safety and tolerability of Brivaracetam (BRV) in focal epilepsy subjects with partial seizures and to evaluate the maintenance of efficacy of BRV over time.
