Active clinical trials for "Carcinoma"

The purpose of this observational study is to assess the role of plasma concentration monitoring of treatment drugs for patients with metastatic renal cell carcinoma (mRCC) in terms of efficacy and side effects. Furthermore, the investigators intend to evaluate the role of anti-drug antibodies, amount of bound drug to T lymphocytes and receptor polymorphisms in CTLA-4 and PD-1 receptors in treatment failure among patients with mRCC treated with check point immunotherapy. Moreover, polymorphisms in the UGT1A1 gene will be correlated with the pazopanib treatment dose.

This is a multi-institutional, prospective, observational registry investigating the safety and efficacy of Accelerated Partial Breast Irradiation (APBI) using a Stereotactic Body Radiation Therapy (SBRT) delivery technique that incorporates real-time image guidance, noncoplanar fields, and respiratory tracking. The study will accrue 200 patients who will be treated to a dose of 30 Gy over the course of 5 fractions. These subjects will then have a follow up time of 5 years

Currently, there are few studies on the diagnostic ability of CEUS-LI-RADS in patients with non-high risk factors for liver nodules. Whether this classification is applicable to such patients remains controversial. There are relatively few studies on the diagnostic efficacy of HCC in clinical diagnosis and the consistency between map readers, and the applicable population is only focused on patients with hepatic fibrosis. Therefore, this study explored the application value of CEUS Li-RADS in liver focal lesions in patients with non-high risk factors for hepatocellular carcinoma.

Genetron Uro V1 perform mutation detection of 17 genes and methylation detection of 1 gene by using urine samples and tumor tissue samples. It is a urine liquid biopsy method that has a great supplementary effect on the existing clinical differential diagnosis technology. The main aim of this study is to compare the test results of Genetron Uro V1 with the standard clinical diagnosis results, and analyze the performance of Genetron Uro V1 in the diagnosis and recurrence diagnosis of urothelial carcinoma.

This study is a prospective, randomized controlled, multicenter clinical study. The purpose of this study is to explore the efficacy and safety of hepatic artery infusion chemotherapy (HAIC) combined with second-line regorafenib and immune checkpoint inhibitors in the treatment of transarterial chemoembolization (TACE) combined with first-line molecular targeted drugs and immune checkpoint inhibitors with low response or failure in advanced hepatocellular carcinoma.

This study explores the use of the Hugo platform to involve study participants in their healthcare and treatments. The Hugo platform may allow researchers to collect better and more accurate real-time health data, from other clinics/hospitals, pharmacies and other electronic devices. The purpose of this research is to see if the use of the Hugo platform is consistent, accurate, cost effective, and time efficient, as it collects and transmits important real-time health information from other clinics/hospitals, pharmacies, and other electronic devices.

Primary objective: The 3-years disease-free survival was compared between low-dose group (30 mCi) and high-dose group (100 mCi). Secondary objective: The successful remnant ablation, efficacy, 3-year progression-free survival and safety were compared between low-dose group (30 mCi) and high-dose group (100 mCi). Research Hypothesis：The 3-year disease-free survival of low-dose group (30mci) may not be lower than that of high-dose group (100 mci) in intermediate-risk thyroid papillary carcinoma patients with no structural or functional lesions and stimulated thyroglobulin(ps-Tg)1-20ng/ml. Study design：Single-center, randomized, double-blinded Sample size：254 patients Follow-up：The measurement of serum thyroid function, thyroglobulin/ anti-thyroglobulin antibody(Tg/TgAb) and neck ultrasonography were performed every 3-12 months during the 3 years according to patients' condition, and computerized tomography(CT) scan, positron emission tomography/computed tomography(PET/CT) and diagnostic whole-body 131I scan were added if necessary. Intervention：Randomly allocated into two groups to receive either 30 mCi (low-dose group) or 100 mCi (high-dose group ) radioiodine for post-thyroidectomy ablation therapy. Evaluation index：Primary evaluation index: The 3-year disease-free survival. Secondary evaluation index: Successful remnant ablation, efficacy, the 3-year progression-free survival and safety.

The goal of this study is Utility of abbrevational magnetic resonance imaging as a screening tool for hepatocellular carcinoma in cirrhotic patients. The primary objective of the study is: • HCC detection rate of US vs AMRI in cirrhotic patients The secondary objective of the study are: False referral rate of US vs AMRI: false referral will be defined as lack of HCC on complete MRI despite a positive US or AMRI. Positive predictive value of US vs AMRI: The positive predictive value will be defined as the number of patients with true positive results in patients with positive US/AMRI. Participants will be evaluated by two rounds of screening 6 months apart using paired US and non-enhanced AMRI.

The aim of this study is to the efficacy, prognosis, adverse effects, and factors for predicting therapeutic effects and clinical prognosis of combined therapy of transarterial chemoembolization (TACE), Anti-VEGF antibodies or pan-target anti-angiogenic drugs, and anti-PD-1/ PD-L1 antibody for advanced hepatocellular carcinoma which initially unsuitable for the radical therapy, including resection, transplantation, or ablation.

This is a Phase 2, multicenter, open-label, 2-cohort (Locoregionally Advanced Cohort or Recurrent/Metastatic Cohort) study evaluating RP3 in combination with concurrent chemoradiation therapy (CCRT) followed by nivolumab (for the LA Cohort) or combined with chemotherapy and nivolumab (for the R/M Cohort) in patients with advanced, inoperable squamous cell carcinomas of the head and neck (SCCHN), including of the oral cavity, oropharynx, hypopharynx, larynx, or unknown primary.
