Filter by:This exploratory study investigates how an imaging technique called 68Ga-FAPi-46 PET/CT can determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulates in normal and cancer tissues in patients with cancer. Because some cancers take up 68Ga-FAPi-46 it can be seen with PET. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors (cancer associated fibroblasts). The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers.
This study will investigate the effects of atezolizumab on select cancer types in people whose analysis of tumour DNA and RNA indicates they may be sensitive to atezolizumab. This study aims to determine if the information from the cancer genome analysis corresponds with the effects of atezolizumab on individuals and their cancer. This is a Phase 2 study, which is undertaken after preliminary safety testing on a drug is completed, and will involve approximately 200 participants. Participants are assigned to one of 8 cohorts based on their primary tumour type: breast, lung, gastrointestinal (GI), primary unknown, genitourinary (GU), sarcoma, gynecological, and 'other' cancer types. Participants in all cohorts will receive the same dose of atezolizumab (1200 mg every 3 weeks). In the first stage for each cohort, 8 participants will be enrolled and if no participants respond to treatment, enrollment to that cohort will be closed. If 1 or more participants respond to treatment, up to 16 additional participants will be enrolled to that cohort. Participants continue on treatment until they no longer may benefit from the treatment or they decide to stop treatment.

This study is to collect and validate regulatory-grade real-world data (RWD) in oncology using the novel, Master Observational Trial construct. This data can be then used in real-world evidence (RWE) generation. It will also create reusable infrastructure to allow creation or affiliation with many additional RWD/RWE efforts both prospective and retrospective in nature.
Patients with suspected cancer (SCAN) and cancer of unknown primary tumor (CUP) are vulnerable because the investigation is difficult and expensive and have poor prognosis because few effective established curative treatments are available. Great progress has been made, for example through highly qualified and systematic clinical investigations not least within the framework of the standardized care processes. However, there is a need for faster, less invasive and more cost-effective tests to confirm or exclude the diagnosis of carcinoma (epithelial cancer), primarily for SCAN and secondly for CUP, and partly to receive suggestions for localization of the primary tumor for primarily CUP and secondly SCAN. There is also a need for prediction of molecularly targeted therapies. New research provides opportunities for using a blood test to acquire detailed and updated information about the individual patient's disease and thus also open new opportunities for faster, less invasive and more cost-effective diagnosis and prediction of molecularly targeted treatments based on individualized sampling and molecular stratification. It is important that these opportunities are tested in a timely fashion in practical health care, so the new opportunities can be taken advantage of and developed in the best way. The aim is to establish a new "best practice" for these hard-to-study and difficult-to-treat patients. Samples will be taken of epithelial cells circulating in the blood, and of the free circulating DNA. As a reference, germ-line DNA will also be sampled, also from regular blood samples. The analyses will show whether the cellular and molecular tests can work in the existing standardized care processes for SCAN and CUP, or if adaptations in routines, training or equipment need to be introduced. The analyses will also give an indication of whether the cellular and molecular sample analyses provide practically useful information for confirming or refuting the diagnosis of cancer, suggesting from which organ the cancer originated and for predicting individualized therapies, and whether adaptations in routines, training or technology need to be introduced.
The PIONEER Initiative stands for Precision Insights On N-of-1 Ex vivo Effectiveness Research. The PIONEER Initiative is designed to provide access to functional precision medicine to any cancer patient with any tumor at any medical facility. Tumor tissue is saved at time of biopsy or surgery in multiple formats, including fresh and cryopreserved as a living biospecimen. SpeciCare assists with access to clinical records in order to provide information back to the patient and the patient's clinical care team. The biospecimen tumor tissue is stored in a bio-storage facility and can be shipped anywhere the patient and the clinical team require for further testing. Additionally, the cryopreservation of the biospecimen allows for decisions about testing to be made at a later date. It also facilitates participation in clinical trials. The ability to return research information from this repository back to the patient is the primary end point of the study. The secondary end point is the subjective assessment by the patient and his or her physician as to the potential benefit that this additional information provides over standard of care. Overall the goal of PIONEER is to enable best in class functional precision testing of a patient's tumor tissue to help guide optimal therapy (to date this type of analysis includes organoid drug screening approaches in addition to traditional genomic profiling).
Substantial progress has been made in the treatment of cancer through the use of targeted therapies, but what works for one patient might not work for another patient. Certain drugs are now being developed that target specific molecules in the body that are believed to be part of the disease. Biomarkers are specific characteristics of the cancer that may help provide prognostic information (e.g. how well patients will be regardless of the treatments given) or help predict sensitivity or resistance to a specific treatment. The study will collect archival tumor samples (previously collected biopsy or surgical tumor samples) to provide biomarker data about a patient's cancer, which may help their physicians to identify which clinical trials of new drug treatments may be most appropriate for the patient in the future and may also guide the use of approved treatments that may potentially benefit the patient. Another goal of this study is to develop a province-wide registry of targeted gene sequencing testing results that will be made available to cancer researchers. Additional tumour tissue and blood samples collected from all study participants will also be stored in a biobank at the Ontario Institute for Cancer Research for future research. The study will also look at linking data from this study to other health care databases to further collect information about the health care the patients received, including medical tests, clinic visits, or procedures both before and after participating in this study. Having more information about patient health to relate to the DNA sequences may provide new insights into cancer and its treatment.
The purpose of this study is to compare the diagnosis accuracy of modified wet suction technique and 5ml dry suction technique on solid occupying lesions.
The optimal treatment of HNCUP remains controversial and lacks evidence from prospective randomized trials. The management of these patients relies primarily on surgery and radiotherapy. The role of radiotherapy in sterilizing putative mucosal sites remains controversial. The main debate concerns the extent of the radiation field. Although pan-mucosal irradiation from the nasopharynx to the hypopharynx and bilateral neck nodes reduces the risk of emergence of a mucosal primary or a nodal relapse, it has been associated with significant toxicity and long-term morbidity (mostly xerostomia and dysphagia). Most single institution retrospective studies have not shown any advantage for more extensive irradiation.Therefore, elective mucosal irradiation may might be appropriate only for these patients.
