Filter by:The study of investigators indicated that TMZ can up-regulate dopamine D2 receptor (DRD2) expression, and mediates Ferroptosis inhibition and chemoresistance of GBM. The clinical data also proved that the DRD2 expression in recurrent GBM is significantly higher than that in primary GBM. Moreover, the DRD2 antagonist haloperidol can attenuate the above function of DRD2, and increase the sensitivity of GBM to the TMZ by inducing fatal autophagy and ferroptosis. In xenograft mice, the combined usage of haloperidol and Temozolomide (TMZ) can significantly inhibit tumor growth and increase overall survival. The investigators' findings have been published in Clinical cancer research. Haloperidol known as a butylbenzene antipsychotic drug, has been widely used in several kinds of mental illnesses, such as depression, schizophrenia, and Bipolar disorder. And the safe dosage of the haloperidol is clear so far. So in this study, the investigators will recruit the patients who suffered from recurrent GBM, and evaluate the effectiveness of single TMZ chemotherapy or combined with haloperidol.
Recurrence after endoscopic papillectomy is described in up to 33% of the cases (range 12-33%). This leads to re-interventions, a cumulative risk of adverse events, and the need for long-term follow-up. Recurrences most likely originate from either the biliary orifice or lateral resection margins. Ablative methods such as radiofrequency ablation (RFA) and thermal ablation by cystotome inside the bile duct have been described to treat intraductal extension of which the use of a cystotome seems to have a more favorable safety profile. However, no studies focusing on the preventive use of these ablative methods in patient with papillary adenomas have been performed.
In this study, 60 patients with HER2 overexpression UTUC with high-risk recurrence factors after radical surgery were proposed to be enrolled, and were assigned to Cohort I (receiving adjuvant therapy group) and Cohort II (refusing to receive adjuvant therapy group) according to the subjects' wishes. Cohort I subjects were treated with vedicloxacinumab in combination with radiotherapy, and vedicloxacinumab treatment lasted for 6 months. Cohort II subjects receive close observation and best supportive care. Safety evaluations and efficacy evaluations will be performed during the study period. Safety Evaluations: Safety evaluations will be conducted within 3 days prior to each dose and will continue until 30 days after the last study dose or initiation of new antitumor therapy for subjects who have received at least one dose of study drug. Evaluation of effectiveness: effectiveness evaluations will be conducted every 12 weeks (±3 days) until imaging-confirmed tumor recurrence, subject death, withdrawal of informed consent, loss to follow-up, or study termination, whichever occurs first. Tumor assessment was performed according to the Criteria for Evaluation of Efficacy in Solid Tumors (RECIST v1.1). For subjects with disease progression, postoperative tumor recurrence, or initiation of other antitumor therapy, survival follow-up was performed every 3 months (window period ± 14 days) from the date of notification to collect information on the subject's subsequent antitumor therapy and survival until the subject's death, withdrawal of informed consent, loss of visit, or study termination, whichever occurred first.
A companion platform trial to test novel targeted agents based on the patient's tumor profile.
Veterans with bipolar disorders (BD) experience recurrent and seemingly unpredictable periods of severe impairments in psychosocial functioning, such as participation in social roles and activities. Many effective treatments for BD emphasize early detection of bipolar episodes, in order to make necessary treatment adjustments and prevent psychosocial impairments associated with acute mood episodes. Unfortunately, acute mood episodes in BD are also associated with a decrease in a patient's insight into their own symptoms, which can prevent one's ability to self-report first signs of symptoms and functional declines. Moreover, routine care visits for BD are typically too infrequent to capture and effectively monitor day-to-day changes in a patient's mood and functioning. Objective, low-effort, and continuous methods of tracking symptoms and social participation of Veterans with BD in real-time and in-situ are needed to provide early (i.e., days in advance) warning signs of acute bipolar episodes and functional declines, which in turn would enable well-timed interventions to prevent poor psychosocial outcomes. mHealth refers to the use of mobile and wireless devices as part of patient care and offers many potential opportunities for early detection of and intervention for acute mood states in this population. However, these mHealth approaches have not been investigated in Veterans with BD. In a Small Projects in Rehabilitation Research (SPiRE)-funded pilot study, the investigator team established high feasibility and acceptability of one such innovative passive mHealth approach using a smartphone program, or an app, in a small sample of Veterans with BD to track their smartphone's GPS/location. The pilot study used a priori location context ratings of visited places (e.g., a priori ratings on types of activities usually engaged in at a frequently visited location) to derive unobtrusive measures of social participation (e.g., time spent at work-related locations). The goal of this Merit Review proposal is to establish reliable and valid machine-learning algorithms using the same types of mHealth data to prospectively (days in advance) detect declines in social participation and prospective onset of mania and depression in Veterans with BD. This proposal has three aims: Aim 1. To establish a machine learning algorithm using GPS/location data for predicting prospective declines in social participation in Veterans with BD. Aim 2. To establish machine learning algorithms using GPS/location data for predicting prospective acute BD clinical states. The investigators will explore whether adding more burdensome daily self-report and voice diaries' speech analysis features improves the models' precision using statistical indices of prediction precision or accuracy. Aim 3. To explore clinical implementation of the mHealth-based algorithms in treatment of BD. Focus groups of VA providers and administrators will assess feasibility of algorithms' implementation in clinical care.
A unique approach for cancer treatment employing intratumoral diffusing alpha radiation emitter device for the treatment of Primary and Recurrent Squamous Cell Carcinoma of the Vulva.
This trial compares detethering surgery and spinal column shortening surgery, two treatments for adults with recurrent tethered cord syndrome (TCS), a neurological disorder where the spinal cord becomes abnormally attached to tissue. Detethering surgery carries a higher risk of postoperative complications such as cerebrospinal fluid (CSF) leakage, while spinal column shortening surgery's comparative efficacy is unclear. This study aims to clarify the optimal surgical management for recurrent TCS in adults, assessing postoperative complication rate and improvement of symptoms.
Hepatocellular carcinoma (HCC) is the most common primary liver tumors. Surgical resection remains the first choice of early stage HCC because the result is superior to other treatments and not limited to liver donation. However, liver resection is criticized that tumor recurrent rate is more than 50% in 5 years although the tumors are completely resected. In our large scale study including 1639 patients with liver resection for HCC, the 1-, 3-, and 5-year disease survival were 73.7%, 58.3% and 53.3%, respectively. Currently there are no effective treatment used as adjuvant therapy to prevent HCC recurrence. Dendritic cells (DC) are the most potent professional antigen-presenting cells, and can capture tumor antigens to provoke antigen-specific cytotoxic T-cells. DC pulsed by tumor associated antigens can be used to proceed tumor-specific immunotherapy. Thereafter, DC pulsed HCC tumor-antigens may be used as an adjuvant therapy to prevent HCC recurrence.
Colorectal cancer is prevented by colonoscopy and polypectomy. Failure to recognize the endoscopic resection scar after Endoscopic Mucosal Resection (EMR) risks unrecognized recurrent or residual adenoma (RRA), which may propagate into post-colonoscopy colorectal cancer. Expert series suggest scar recognition and interrogation is well performed with a high negative predictive value of endoscopic imaging vs histopathology. In this study the authors will investigate the performance of endoscopic imaging in detecting RRA at an endoscopic resection scar amongst general endoscopist and the impact of a learning intervention on recognition of RRA.
The purpose of this study is to determine how safe and how well-tolerated the experimental study drug, C134 is when re-administered into the brain where the tumor is located.
