Active clinical trials for "Carcinoma"

A unique approach for cancer treatment employing intratumoral diffusing alpha radiation emitter device (DaRT) as a treatment prior to additional radiation or chemo therapy.

Hepatocellular carcinoma (HCC) is the 7th most common cause of cancer death globally but only 20% are diagnosed in its early stages where cure is possible. Current standard-of-care surveillance of patients at high risk of developing HCC with 6-monthly serum alpha-fetoprotein (AFP) and ultrasound imaging (US) has a sensitivity of approximately 63% for detecting early HCC. There is an urgent need for a more efficacious and convenient modality of surveillance of high-risk patients to diagnose HCC at an early stage. This prospective study aims to address this unmet clinical need by validating a panel of circulating miRNA biomarkers to develop an in-vitro diagnostic (IVD) kit for the detection of early HCC in a cohort of high-risk patients. Additionally, this study also aims to develop a multi-parametric MRI-based AI algorithm to quantify individual risks of developing HCC and to predict the progression of chronic liver disease in this cohort to enable targeted surveillance. Lastly, by identifying changes in the microbiome and metabolites as HCC develops in this cohort enables the establishment of actionable biomarkers that can prevent and predict the development of HCC.

Clinical trial to determine the efficacy (sensitivity and specificity) of Anchordx's urine DNA methylation/somatic mutation assay for detecting upper tract urothelial carcinoma compared to pathology in patients.

This study is a prospective, open label, multicenter, randomized controlled clinical trial. The main purpose of the study is to evaluate the efficacy and safety of nimotuzumab combined with concurrent radiotherapy versus radiotherapy alone in high-risk patients with HNSCC not suitable for cisplatin after surgery. The subjects were randomly divided into study group (nimotuzumab combined with concurrent radiotherapy) and control group (radiotherapy alone) by 1∶1 stratified random method.

SMARCB1-deficient sinonasal carcinoma is very locally advanced malignancy at diagnosis which often precluded upfront radical resection. The investigators are now proposing a phase II single-arm study on tazemetostat in combination with docetaxel, cisplatin and 5-FU (known as TPF regimen) as preoperative therapy for locally advanced non-metastatic SMARCB1 (INI-1)-deficient sinonasal carcinoma, followed by radical resection and/or post-operative radiation therapy (with or without concurrent chemotherapy), and tazemetostat for another 6 months. It is hypothesized that addition of tazemetostat will improve objective response rate, resectability rate, orbit preservation rate after surgery, and hopefully survival outcomes with manageable safety profiles.

This study evaluates a concept called 'Teaching the Teachers' and whether it is helpful in disseminating guidelines on the national and international levels. "Teaching the Teachers" involves teaching the guidelines to experts who later teach the same guidelines to other radiologists, trainees, and physicians to assume the teacher's role and disseminate the guidelines and so on.

The aim of this study is to compare the efficacy of the Sentimag localization system and its tracer Magtrace, superparamagnetic iron oxide nanoparticles, as a tracer in sentinel node biopsy in breast cancer with Tc99 in a single-center prospective study. The other part of the study will be the implantation of the smallest non-radioactive seed, Magseed, in the non-palpable breast cancer lesions. Another part of the study will be the implantation of Magseed in the positive axillary lymph nodes in patients diagnosed with clinically positive lymph nodes that will receive neoadjuvant systemic therapy.

The purpose of this study is to explore the efficacy and safety of a combination of GP chemotherapy and tislelizumab in neoadjuvant therapy combined with tislelizumab in adjuvant therapy of locoregionally advanced nasopharyngeal carcinoma patients.

Background: Despite a favorable prognosis, metastatic cervical lymph nodes (LN), are not uncommon among patients with differentiated thyroid cancer (DTC). Current guidelines recommend that a suspicious cervical LN on neck ultrasound (US) should be investigated with fine needle aspiration biopsy for cytology (FNAC) and for thyroglobulin (Tg) measurement (FNA-Tg), using saline washout of the needle content. Since Tg is a protein produced exclusively by thyroid follicular cells, a positive FNA-Tg result establishes the diagnosis of metastatic DTC. Currently, following LN biopsy, a patient must wait days to weeks to receive results, that directly impacts the treatment plan. This delay may be solved by a point of care assay of the washout Tg (POC-Tg), drawn from a suspicious cervical LN. Another potential novel usage of POC-Tg is the evaluation of suspicious LN found during neck surgery for known or suspicious DTC. Here, the POC-Tg may save the time needed for the completion of 'frozen section'. The study product: POC-Tg is a lateral flow immunoassay for Tg, able to detect within minutes Tg at concentration equal to 5 ng/mL and above (the midrange of the accepted cut-off). Methods: The multi-center validation study will include 100 patients in the FNA clinic, and 150 LN (dissected from 50-150 patients) in the operating room (OR). Each LN will be evaluated using both the formal accepted method (in the FNA clinic, the combination of FNAC and FNA-Tg; and frozen section in the OR), and the novel POC-Tg. Clinical decisions will be made according to the formal evaluation only. In a retrospective analysis, the investigators will estimate the sensitivity and specificity of the POC-Tg and the formal accepted method against the reference ('gold') standard (cytology, histology and follow-up US in the FNA clinic setting, and final histology in the OR setting).

This early phase I trial evaluates blood samples to see if patients undergoing standard of care treatment with either stereotactic body radiation therapy or percutaneous ablation (using radio waves to create heat to destroy the tumor), have an increase in serum immune markers in kidney cancer. Information gained from this study may help doctors make treatment decisions for patients with kidney cancer.
