Filter by:Background: Exercise, or physical activity, is beneficial for all cancer survivors. Despite this knowledge, there is generally a gap between the evidence and practice. And this gap is widened with (a) underserved tumour groups in exercise oncology, such as neuro-oncology patients, or (b) underutilized timelines across the cancer treatment phases to deliver exercise oncology education or programming. Thus, our current work is building a hybrid implementation effectiveness study into the clinical care pathway across Alberta in neuro-oncology - ACE-Neuro. Objectives: The purpose of this study is to assess the impact of an online, tailored exercise oncology program for neuro-oncology patients using a participant-oriented research (POR) approach as well as both quantitative and qualitative research methods. Specifically, the primary outcome of this study is to determine the feasibility of recruitment, referral, triage, adherence, and adverse events. The secondary outcome is to examine the preliminary effectiveness of the neuro-oncology exercise program on patient-reported outcomes and physical function. Methods: Neuro-oncology patients >18 years and able to consent in English will be referred to a study-based Rehabilitation Triage Clinic, where a Physician-Researcher will assess patients on their overall health and functional status, and next triage them to either ACE-Neuro, rehabilitation oncology, or cancer physiatry. Once referred to ACE-Neuro, participants will partake in a 12-week online exercise program, delivered by a Clinical Exercise Physiologist. Participants will complete online assessments of physical function, patient-reported outcomes, and objective physical activity at baseline (pre-program), 12-weeks (post-program completion), 6-months, and 12-months. The exercise program includes weekly one-on-one online exercise delivery, health coaching to support behaviour change, and access to an online group exercise session. Participants will also be invited to a post-program qualitative interview to get perspectives on their experiences participating in ACE-Neuro. Relevance: By working directly with patients, healthcare providers, and community partners, this implementation project will develop a framework that streamlines patient triage, and provides a tailored online exercise program for neuro-oncology patients, thereby advancing exercise oncology research and clinical practice.
Patients with a new diagnosis of high-grade glioma based on MRI, who are considered surgical candidates determined by neurosurgeons or patients with recurrent glioblastoma with the initial diagnosis of glioblastoma (histologic or molecular proof) and recommended for clinically surgical resection may be eligible for this study. Subjects may participate in this study if they are at least 18 years of age. Ferumoxytol-enhanced MRI will be used to quantify tumor-associated macrophages. This is a non-therapeutic trial in that imaging will not be used to direct treatment decisions. The blood draw is being completed to evaluate cell-free circulating tumor DNA (cfDNA) and cell-free tumor DNA (ctDNA).
The objectives of this registry study are to evaluate real-world clinical outcomes and patient reported outcomes that measure the effectiveness and safety of STaRT.
We planned to evaluate the change in tumor dimensions of intraaxial parenchymal tumors after craniotomy by comparing the tumor size on intraoperative ultrasonography (IOUSG) with pre-operative CECT and CEMRI brain.
Surgery for brain gliomas is usually guided by different imaging techniques including neuronavigation MRI and intraoperative ultrasound that do not allow visualization of the low-density peri-lesional tumor infiltration present in gliomas and from which the tumor recurs. Another important aspect in the management of glial tumors is the histological grade. The appearance of new vessels (called neo-angiogenesis) is one of the crucial steps in the life of these tumors, which signifies the transition to anaplasia. This neoangiogenesis is diagnosed during the anatomopathological analysis of the operative specimen, and may be suspected on preoperative MRI on the so-called infusion sequences. The objective of this project is to evaluate the potential of two ultrasound modalities - elastography and ultrasensitive Doppler - in helping the surgical management of brain tumors. Ultrasound elastography measures cerebral elasticity and thus indirectly the degree of tumor infiltration; while ultrasensitive Doppler measures intratumoral vascularization, and could therefore help in the diagnosis of tumor anaplasia.
Many patients with primary brain tumors experience cognitive deficits and cognitive rehabilitation programs aim to alleviate these deficits.The cognitive rehabilitation program developed by the investigators proved effective in a large randomized controlled trial (RCT). To increase its accessibility, it was converted into the iPad-based cognitive rehabilitation program ReMind, which incorporates psychoeducation, strategy training and retraining. A pilot study and a randomized controlled trial are conducted, to evaluate the feasibility of the use of the program and the efficacy of the program in brain tumor patients after resective surgery.
To investigate a computer-based Cognitive Remediation Therapy (CRT) for brain tumor patients at the Massey Cancer Center on measures of cognitive functioning (e.g., working memory, attention, processing speed, language, visuospatial functioning, immediate and delayed memory, or executive functioning) over time.
Primary malignant and non-malignant brain tumors account for an estimated 21.42 cases per 100,000 for a total count of 343,175 incident tumors based on worldwide population estimates [1]. These entities result in variable but disappointing rates of survival, particularly for primary brain tumors (5-year survival rates: anaplastic astrocytoma 27%; glioblastoma multiforme 5%) [2, 3]. Metastatic brain tumors outnumber primary brain tumors (estimates as high as 10:1) as they affect approximately 25% of patients diagnosed with cancer [4-6]. In terms of brain tumor surgery, the extent of surgical resection-a factor that is greatly impacted by a Neurosurgeon's ability to visualize these tumors-is directly associated with patient outcomes and survival [7-9]. Although spinal cord tumors are lower in terms of their incidence [10], data correlating extent-of-resection to outcomes and survival have been demonstrated in patients with intramedullary tumors [11]. Using systemically delivered compounds with a high sensitivity of detection by near-infrared (NIR) fluorescence, it would be possible for us to improve surgical resection thus minimizing chances of recurrence and improving survival. Simply, if the tumor cells will "glow" during surgery, the surgeons are more likely to identify tumor margins and residual disease, and are, therefore more likely to perform a superior cancer operation. By ensuring a negative margin through NIR imagery, it would make it possible to decrease the rates of recurrence and thus improve overall survival. This concept of intraoperative molecular imaging requires two innovations: (i) a fluorescent contrast agent that can be injected systemically into the subject and that selectively accumulates in the tumor tissues, and (ii) an imaging system that can detect and quantify the contrast agent in the tumor tissues.[12, 13] Subjects undergo intraoperative imaging, receiving an injection of indocyanine green and then undergoing intraoperative imaging of the surgery site with a NIR imaging system. The imaging devices allow the operating field to be observed in real-time.
The purpose of this study is to evaluate the safety and efficacy of administering the medication capecitabine along with temozolomide when you start your monthly regimen of oral temozolomide for the treatment of your newly diagnosed glioblastoma multiforme (GBM). Capecitabine is an oral chemotherapy that is given to patients with other types of cancer. The study will evaluate whether the dosage of 1500 mg/m2 of capecitabine is tolerable after radiation, when taken along with temozolomide. It will also try to determine if the medication capecitabine helps patients respond to treatment for a longer period of time compared to just temozolomide alone, which is the standard of care.
Patients having radiotherapy to their head and neck wear an immobilisation shell to prevent patient movement and improve treatment accuracy. These shells tend to cover the face and have the potential to cause anxiety and distress in patients, particularly if they suffer with claustrophobia or a similar fear. The study will use an 'open-face' shell that does not cover the face and compare this with the investigators' current 'closed-face' shell. The investigators will obtain treatment verification x-ray images to assess the daily set-up errors and compare these between the two shell type, and ask both patients and radiographers of their experiences from using the shells. Hypothesis: Open-face immobilisation shells offer equivalent accuracy and efficiency of radiotherapy delivery and are better accepted by patients and radiographers as compared to closed-face immobilisation shells for cranial radiotherapy.
