Filter by:This study will evaluate the clinical response and safety of cone beam computed-tomography guided percutaneous cryoablation in bone metastases from thyroid, adrenal and neuroendocrine tumors in 30 patients.
This is a prospective observation study in patients with non-small cell lung cancer (NSCLC) starting either cytotoxic chemotherapy or radiation therapy. It will assess changes in circulating tumor DNA (ctDNA) in the days following the initiation of treatment, as well as longitudinal monitoring, to assess the dynamics and value of ctDNA in stage III-IV NSCLC.
This study will use a stepped-wedge cluster randomized trial to evaluate the effect of a health system initiative using machine learning algorithms and behavioral nudges to prompt oncologists to have serious illness conversations with patients at high-risk of short-term mortality.
Our objective is to determine if the combination of simple ultrasound features (IOTA simple rules) and a new biomarker (HE4) together with a common tumour marker (CA 125) can accurately predict ovarian cancer in women found to have a pelvic mass on ultrasound. The investigators hypothesize that the use of two biomarkers (HE4 and CA 125) in a mathematical algorithm (Risk of Malignancy Algorithm, ROMA) can be used to predict malignancy in a pelvic mass which has indeterminate ultrasound features. This is a prospective cohort study involving women undergoing operation for a pelvic mass. 720 women scheduled to have an operation to remove a pelvic mass would be recruited from 3 hospitals (QMH, UCH and PYNEH). Pre-operatively, each woman will have an ultrasound assessment using the IOTA simple rules criteria and have blood taken for tumour markers HE4 and CA 125. In women where IOTA ultrasound rules are inconclusive, 2 strategies for prediction will be compared - calculation of risk by ROMA (Strategy A) vs referral for an expert ultrasound (Strategy B). These pre-operative risk predictions will be correlated with the final pathology found at the operations. Main outcome measures include the sensitivity, specificity, positive and negative predictive powers for Strategy A compared to Strategy B. Sensitivity and specificity will be compared using the McNemar test. Area Under the ROC Curve (AUC) will be calculated and compared using the Delong method for the 2 strategies. The investigators expect AUC of both strategies will be similar. This would suggest that ROMA can replace expert ultrasound in the pre-operative prediction of ovarian cancer.
This trial was a single-center, open-label, dose-increasing Phase I clinical study with subjects enrolled in patients with advanced solid tumors who failed standard treatment or who were unable to receive effective treatment. The trial is divided into two stages: dose escalation and dose extension.
This is a 2 part study. Part 1 is to evaluate the efficacy and safety of dostarlimab plus carboplatin-paclitaxel followed by dostarlimab versus placebo plus carboplatin-paclitaxel followed by placebo; and Part 2 is to evaluate the efficacy and safety of dostarlimab plus carboplatin-paclitaxel followed by dostarlimab plus niraparib versus placebo plus carboplatin-paclitaxel followed by placebo in participants with recurrent or primary advanced (Stage III or IV) endometrial cancer.
The goal of this observational study is to collect data on efficacy and safety of microwave ablation (MWA) used to treat subjects with primary and secondary liver malignancies and renal malignancies. The main question it aims to evaluate the short, medium and long-term clinical course of patients treated with MWA. Participants will not alter their normal clinical and therapeutic practice, due to the observational nature of the study, and all data regarding microwave treatments will be collected (including demographic data). follow their normal clinical and therapeutic path
This is a prospective, multi-centre, open label, non-randomized phase II study evaluating the efficacy and safety of nivolumab plus platinum-based chemotherapy in patients with advanced G3 NENs of the GEP tract or of UK origin.
This is a Phase I, open-label study to assess the safety, tolerability, pharmacokinetics and anti-tumor activity of AZD4635 in Japanese patients with advanced solid malignancies. This study consists of 2 cohorts, Cohort1 and Cohort2. At least 3 or up to 6 evaluable Japanese patients with advanced solid malignancies will be enrolled in Cohort1 and 6 evaluable patients will be enrolled in Cohort2.
This trial studies how well new magnetic resonance imaging (MRI) and magnetic resonance spectroscopic imaging (MRSI) software works in improving the image quality of scans in both patients and healthy volunteers. Improving the image quality of MRI and MRSI through new software may lead to implementation of these techniques and better clinical care for patients.
