Filter by:The goal of this diagnostic test is to prospectively test the performance of pre-developed artificial intelligence (AI) diagnostic model for detecting pathological lymph node metastasis (LNM) of prostate cancer. Investigators had developed this AI model based on deep learning algorithms in preliminary research, and it performed well in retrospective tests. Investigators will compare the diagnostic performance (sensitivity, specificity, etc.) of the AI model and routine pathological report issued by pathologists, to see if the AI model can improve the clinical workflow of pathological evaluation of LNM in prostate cancer in the real world.
The goal of this multi-centre, prospective study is to assess the frequency of asymptomatic brain metastasis in patients with stage II or III Triple Negative or HER2 positive breast cancer. The main questions it aims to answer are: 1. What proportion of patients with stage II or III Triple Negative or HER2 positive breast cancer have asymptomatic brain metastases identified on a screening contrast-enhanced magnetic resonance imaging (or computed tomography when Magnetic resonance is not possible) of the brain? 2. How do patients feel about undergoing brain imaging to screen for asymptomatic Brain metastasis? 3. What clinical and tissue-based biomarkers are associated with asymptomatic detection of Brain metastasis? Participants will undergo a brain imaging, collect one blood sample to perform ctDNA analysis, and fill the Testing Morbidities Index (TMI) after imaging is done. Procedures must take place within one year of initial diagnosis, either prior to or after completion of (neo)-adjuvant systemic therapy.
This study assesses the safety and efficacy of TXA for patients treated for pathological femur fractures using modular prosthetics.
The goal of this single-center prospective randomized controlled trial is to test and compare the safety and effectiveness of autologous blood transfusion in spinal surgery for lung cancer spinal metastases. The main questions it aims to answer are: - Does autologous blood transfusion increase the incidence of new metastases? - Does autologous blood transfusion affect postoperative hemoglobin levels and the number of circulating tumor cells in the blood? - Can autologous blood transfusion reduce the rate of allogeneic transfusion during and after surgery for spinal metastases?
This study aims to evaluate the safety and efficacy of hippocampal-sparing WBRT combined with SRS as first-line treatment for SCLC patients with brain metastases.
This study involved a comprehensive analysis of 256 PTC patients from Sun Yat-sen Memorial Hospital of Sun Yat-sen University (SYSMH) and 499 patients from The Cancer Genome Atlas. DNA-based next-generation sequencing (NGS) and single-cell RNA sequencing (scRNA-seq) were employed to capture genetic alterations and TME heterogeneity. A deep learning multimodal model was developed by incorporating matched histopathology slide images, genomic, transcriptomic, immune cells data to predict LNM and disease-free survival (DFS).
The goal of this interventional phase III clinical trial is to evaluate objective intracranial response rate (iORR) after a treatment with total cranial radiation therapy plus concomitant transdermal nitroglycerin (NTG) addition or total cranial radiation therapy only in patients with stage IV non-small cell lung cancer with brain metastases and EGFR mutation. The main questions it aims to answer are: Determine progression-free survival (PFS) to CNS and overall survival (OS). Evaluate and compare the quality of life (QoL) of patients during and after treatment. Evaluate the cognitive function of patients before, during and after treatment. Evaluate treatment-associated toxicity to grade adverse treatment events Evaluation of HIF1α, VEGF and ROS1 in peripheral blood before and after nitroglycerin treatment. All participants will have laboratory tests at the beginning and end of radiation therapy. Cranial MRI will be performed prior to treatment and 12 weeks after the end of treatment, then every 16 weeks until intracranial progression. Patients in the interventional group will be given 36 mg patches of transdermal nitroglycerin for 24 hours with a 12-hour rest interval during treatment with radiation therapy. The control group will only receive total cranial radiation therapy at the same doses and with the same schedule.
This is a multicenter, single-arm, long-term safety and tolerability trial. A total of 300 subjects with chronic kidney disease on hemodialysis are planned to be enrolled.
The purpose of this non-randomized, prospective study is to assess the feasibility of planning and delivering conventional palliative radiotherapy to bone metastases on previously available diagnostic CT scans (dCT). Objectives:1) dosimetric accuracy of palliative radiotherapy designed on a dCT compared to a CT simulation 2) assess suitability of patient set up using surface landmarks and kilo voltage (kV) imaging 3) determine the proportion of patients who can receive radiotherapy designed on a dCT 4) confirm eligibility criteria for appropriate patients in clinical practice All enrolled patients will undergo a CT simulation with tattoos as per current standard of care.The radiation oncologist will place fields on the dCT and CT simulation. Radiotherapy will be planned on both CT scans and reviewed for quality by both the radiation oncologist and medical physicist.
The goal of this intervention program is to provide the feasibility of a culturally adapted version of the SOLAR program among mental health and psychosocial support (MHPSS) workers who provide psychological or psychosocial support to the survivors of the earthquakes on February 6, 2023, in Türkiye. The main questions it aims to answer are: 1. Will the SOLAR Group Program reduce psychological distress at the post-test and follow-up compared to the pre-test? 2. Will the SOLAR Group Program reduce secondary traumatic stress at the post-test and follow-up compared to the pre-test? 3. Will the SOLAR Group Program reduce anxiety and depressive symptoms at the post-test and follow-up compared to pre-test? Participants will be asked to sign a consent form. Upon accepting it, they will fill out: - a demographic form, - the Kessler Psychological Distress Scale (K10), - Assessment of Suicidal Thoughts for the screening. Before the SOLAR intervention program, participants will be asked to complete: - the Secondary Traumatic Stress Scale (STSS), - Generalized Anxiety Disorder-7 (GAD-7), - the Patient Health Questionnaire (PHQ-9) if they approve participation in these surveys. After collecting their pre-test scores, they will receive the SOLAR intervention program. During the program, they will be asked to participate in each session, lasting 5 weeks. After the program, they will be asked to participate process evaluation interview.
