Filter by: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;
The purpose of this research study is to determine if lattice radiation therapy (LRT) will provide better treatment for bulky (large) tumors than current standard of care radiotherapy.
Patients with symptomatic spinal metatstasis will be prosepectively included in a database after theu signes informed consent. Minimally six months after inclusion the survival status is analyzed. These are correlated with factors that are used in an earlier develloped prediction model
This study was a retrospective observational study. The study included patients with non-small cell lung cancer with ALK-fusion brain metastases or meningeal metastases who received first-line and late-line treatment with the third-generation ALK TKI lorlatinib between June 2022 and June 2023. Data were collected from the electronic medical records database and hospital information system of many hospitals in Sichuan Province. Clinical pathology features including gender, age, ALK mutation status at diagnosis, and clinical stage at diagnosis were collected from the medical records. The physical condition assessed by ECOG-PS before the administration of lorlatinib was recorded. Information on anti-tumor therapy was obtained from the records, including dose and time of ALK-TKI therapy and tumor response, number of prior systemic therapy lines, drug regimen, efficacy, and whether local therapy such as radiotherapy and surgery had been received. In this study, the sample size is not limited, and information is collected according to the maximum number of patients. The study period was from 01 July 2023 to 30 June 2024.
The main objective of this study is to test if adding the mistletoe extract Iscador® Qu to regular cancer treatment with immune checkpoint inhibitors affects: - The immune system's ability to fight cancer - Safety of the treatment - How well the treatment performs against cancer - How the patient feels during treatment Researchers will compare patients treated with immune checkpoint inhibitors plus Iscador® Qu with patients treated with imune checkpoint inhibitors only.
This study is an ambispective cohort study to evaluate the displacement and deformation of large brain metastases (BM) treated with magnetic resonance imaging-guided adaptive radiotherapy (MRIgART)
A complete omentectomy is typically recommended during radical total gastrectomy for gastric cancer, though its impact on survival remains unclear. This study aimed to assess the frequency and risk factors of metastases in the greater omentum in gastric cancer patients undergoing gastrectomy. It will involve a single prospective cohort of consecutive patients who underwent total gastrectomy with complete en bloc omentectomy and modified D2 lymphadenectomy. Post-surgery, the omentum will dissect from the gastrectomy specimen beyond the gastroepiploic vessels and examine separately for pathological assessment. The primary outcome will focus on the detection of omental metastases.
