Active clinical trials for "Neoplasm Metastasis"

Clinical results on intra-arterial adjuvant chemotherapy for prevention of liver metastasis following curative resection of pancreatic cancer

The great promise of PET/MR for assessment of skeletal metastatic involvement is derived from the extensive experience with stand- alone MR, but initial data on the use of PET/MR for assessment of bone pathology indicate that PET/MR introduces unique issues that should be addressed when determining its role in this clinical scenario. In this study cohort includes 150 patients 18 years or older, having metastatic skeletal involvement on baseline PET/CT prior to treatment. Baseline studies and follow up studies of the patients referred post treatment, will be reviewed. The main goal of the study is to asses the accuracy of PET/MR in detection and monitoring response of bone metastases.

This is a nationwide cohort study on real-world patients (n≈30,000) surviving a first myocardial infarction (MI) 2006-2013 and alive to attend a routine 1-year follow-up. Associations between Socioeconomic Status (SES) and secondary preventive actions (SPAs) throughout the first year is studied and assessed as possible mechanisms underlying the increased risk of a first recurrent hard cardiocvascular (CV) outcome, recurrent atherosclerotic cardiovascular disease (rASCVD), in patients with low Socioeconomic Status during long-term follow-up (2006-2018).

The aim of the present study was to quantitatively assess the risk factors that may affect the re-occurrence of a CVD event and the use of a commercially available mobile application Samsung Health for the assessment of parameters of exercise tolerance and the ECG M-Trace Base II application for the assessment of cardiological parameters.

To establish and validate a suitable and practical nomogram for primary hospitals to predict the risk of central lymph node metastasis (CLNM) among thyroid papillary carcinoma (PTC) patients based on clinical and ultrasound characteristics among Chinese population，1000 PTC patients were retrospectively reviewed who underwent bilateral thyroidectomy or lobectomy plus central lymph node dissection（CLND） between June 2014 and September 2019 in Sun Yat-sen Memorial Hospital (Guangzhou, South China), and then LASSO regression analysis was performed to screen out the possible predictors. Another 200 PTC patients from the First Affiliated Hospital of Zhengzhou University (Zhengzhou, North China) who underwent bilateral thyroidectomy or lobectomy plus CLND between March 2019 and November 2020 were enrolled to construct the nomogram. The area under the receiver operating characteristic (ROC) curves (AUC), calibration curves and decision curve analysis (DCA) were used to evaluate the nomogram.

Contrast-enhanced intraoperative ultrasound (CE-IOUS) plays an increasingly important role in the surgical therapy planning of primary liver lesions as well as liver metastases. The present study was designed to evaluate the significance of CE-IOUS by specificity and sensitivity and particularly the impact it exerts on the surgical strategy. A secondary aim was assessing the outcome relevance of surgeries influenced by CE-IOUS.

Indocyanine green (ICG) is a water-soluble organic dye that is cleared totally through the hepatobiliary system. It has a half-life of 3-4 mins, which allows repeated applications. Near-infrared (NIR) fluorescence imaging with indocyanine green (ICG) imaging has been recently introduced, and has been suggested as a useful tool for the identification and preservation of the parathyroid glands (PGs) during total thyroidectomy (TT). ICG can also be used for sentinel lymph node (SLN) biopsy to predict the micrometastases in central lymph nodes (CLN) in thyroid carcinoma, and central lymph node dissection can reduce local recurrence.

This study will be conducted to evaluate the clinical performance and validity of both light-induced fluorescence intraoral camera and laser-induced fluorescence device in comparison to visual-tactile assessment method in detection of secondary caries around margins of resin composite restorations.

The number of metastases in a patient with primary or recurrent prostate cancer has major prognostic implication. The purpose is to compare, in a pilot study, the diagnostic performance of 18F-NaF-PET/MR with respect to the results of the scintigraphy 99mTc-MDP-SPECT/CT (routine exam) for determining the presence or absence of bone lesions in prostate cancer patient, with up to five metastases (oligo-bone metastatic) based on scintigraphy 99mTc-MDP-SPECT/CT. The gold standard will be a combination of clinical follow-up, additional imaging and biopsy, as indicated by the multidisciplinary discussion at the tumor board. The findings from whole-body 99mTc-MDP-SPECT/CT, 18F-NaF-PET/MR, and the combination of the 2 modalities will be categorized by 2 teams of 2 readers as benign or probably benign, equivocal, or malignant or probably malignant and compared with the results of follow-up for JAFROC and ROC analysis.

The aim is to identify in patients with brain metastases the predictive factors of overall survival, survival without local recurrence and survival with progression-free brain metastases after complementary whole brain radiotherapy.
