Active clinical trials for "Neoplasm Metastasis"

To compare increasing doses and different treatment schedules of stereotactic body radiation therapy (SBRT) against standard treatment scheduling.

Every professional working in the medical field may encounter medical errors and patient safety issues during their careers. Wu, et al. He coined the term 'second victim', which was used for the first time in 2000. In a patient safety incident, the patient is the first to be affected, while the second to be affected are the healthcare professionals (physicians, assistants, nurses, and medical staff) who are the potential causes of the incident and who are adversely affected by the consequences of this incident. That is, secondary victims are characterized as healthcare professionals who are involved in unexpected adverse patient events and experience occupational or psychological difficulties. Almost half of healthcare professionals have been reported to experience the second victim phenomenon during their professional careers. Medical errors or adverse events can deeply affect healthcare professionals and have long-term effects, leading to permanent consequences. In the medical field, identifying the origins of errors plays a vital role in preventing future errors. Second victims can encourage constructive change by not only criticizing the healthcare system but also contributing to the improvement of healthcare institutions. Burlison and his team developed and validated a tool they called the "Second Victim Experience and Support Tool" (SVEST) to understand the coping process of second victims and identify necessary support resources. Koca and colleagues conducted a validation study of the translation and psychometric evaluation of the SVEST (T-SVEST) in Turkey. Our study aims to evaluate the secondary victim experience of anesthesiologists and the quality of support resources.

Research has found that patients with microsatellite instability (dMMR/MSI-H) type colorectal cancer can achieve long-term survival through immune checkpoint inhibitors (ICIs) treatment, but currently accounting for about 95% of MSS type mCRC, the benefits from immune checkpoint inhibitors are very limited. REGONIVO is a Phase Ib study to explore the efficacy and safety of regorafenib in combination with nivolumab in the treatment of gastric cancer and colorectal cancer with MSS. The study enrolled 50 patients with advanced disease, including 25 cases of gastric cancer, 25 cases of colorectal cancer, except for one case of colorectal cancer with MSI-H, and others were MSS type. The results of the study showed that patients with colorectal cancer had an objective response rate (ORR) of 36%.The ORR of liver matestasis vs. lung matestasis is 8.7% vs. 50%. In this study, pMMR /MSS type patients with refractory advanced colorectal cancer without liver metastasis were selected as the subjects. Regorafenib, Sintilimab and Celecoxib were used to evaluate the maximum tolerable dose, objective response rate (ORR), total survival time (OS), progression free survival time (PFS), disease control rate (DCR), response duration (DoR) and safety of the subjects.

This study is a prospective, multicenter, randomized controlled clinical trial to evaluate the safety and efficacy of polyvinyl alcohol sodium acrylate embolization microspheres and HepaSphere Microspheres loaded with irinotecan for the treatment of colorectal cancer with hepatic metastases through arterial chemoembolization.

Cerebrospinal fluid was obtained from the cerebrospinal cavity of non-small cell lung cancer patients with central nervous system metastasis, blood was obtained from veins, and metastatic lung cancer tumor tissue was obtained from surgically resected brain tumors or meningeal tumors. Then comprehensively analyze the exosomes contained in the aforementioned samples, and compare and analyze the clinical data of the patients, so as to explore whether the cancer cell-related substances contained in the cerebrospinal fluid, blood and tumor tissue can be used to predict lung cancer metastasis and Bioindicators of treatment effect.

This is a prospective, single-center, randomized study directly comparing outcomes after MR guided high intensity focused ultrasound (MR HIFU) or external beam radiation therapy (EBRT) treatment of painful bone metastases.

The proposed research consists of engagements with terminal cancer patients and their friends and family as they engage in end-of-life planning.

In oncology, therapeutic progress has allowed a significant increase in life-expectancy: a growing number of cancer survivors live to more advanced metastatic stages. Consequently, the prevalence of secondary bone lesions is increasing, which are frequent and disabling. They are responsible for pain and a high risk of pathological fractures. The average prevalence of pain in cancer represents 53% for all stages combined and 64% for metastatic stages. Analgesics, radiotherapy and surgery are widely used in this context, but are not without side effects. Cementoplasty is an interventional radiology procedure that has improved the palliative management of bone lesions. It consists of a percutaneous injection of polymethylmethacrylate-based cement, whose physical and chemical properties provide resistance to compressive stress during weight-bearing activities. However, one of the main disadvantages of cement is its low resistance to torsional stress, as evidenced notably in vitro tests. Thus, cementoplasty alone is very effective at the spinal level (compressive forces) to reduce pain and risk of fracture, but much less effective at the level of other bones that are subjected to torsional stresses, notably the pelvis and femur (40% fracture rate at one year after cementoplasty alone of femoral metastasis). Fixation using a combination of metal screws and cement provides resistance to torsional and compressive stress. In addition, it has been shown that there is a significant risk of secondary screw displacement if screws are not combined with cement in secondary bone lesions. Combination of percutaneous screw fixation and cementoplasty is a mini-invasive procedure which allows limiting complications and the duration of treatment: early standing up, almost no blood loss, reduced risk of venous thromboembolism (VTE), rapid healing.

This study will carry out a prospective cohort study to study the effect of different primary leison treatment modes on disease control, quality of life, economic cost and survival period of patients with bone metastases from breast cancer and lung cancer by giving radiotherapy or palliative surgery or not giving local treatment for the primary lesion in patients with bone metastases from breast cancer or lung cancer

Intermittent Ramadan fasting was associated with a risk of complications in patients with adrenal insufficiency. A risk stratification with recommendations (lifestyle and drug adjustment) for fasting in these patients has been recently published. So, this prospective interventional study was carried out to evaluated these recommendations. Patients with secondary adrenal insufficiency and willing to fast Ramadan were included. Before Ramadan, patients underwent a clinical examination and were educated for lifestyle measures and the schedule of glucocorticoid replacement therapy was adjusted. The occurrence of complications and the number of fasted days during the month of Ramadan 2023 were reported and compared with those of Ramadan 2022.
