Active clinical trials for "Neoplasm Metastasis"

In renal cell carcinoma (RCC) patients, lymph node metastases detection and treatment are the most critical issues in daily clinical decision-making. Indeed, conversely to other oncological settings, a) nodal status imaging, b) sentinel node technique and c) standard lymphadenectomy have been demonstrated inadequate in the staging and management of RCC patients. A novel, accurate, standardized imaging technique is urgently needed in RCC setting to detect macro and micro nodal invasion, to identify those patients who are at higher risk of having nodal metastases, to accurately plan the best management. Recent studies suggested combining 18F-FAZA PET with CT scanning in the detection of cancer-induced hypoxia.The investigators propose to test 18F-FAZA PET-CT in detecting nodal metastases to improve the management of RCC patients.

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

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 aim of this study is to evaluate the prevalence of secondary hyperparathyroidism among patients with diabetic nephropathy.

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.
