Active clinical trials for "Neoplasms"

This study is designed to evaluate the efficacy and safety of the combination of Anlotinb and JS001 in EGFR-TKI resistant T790M-negative NSCLC patients.

This study propose to investigate the immune repertoire of MM patients at the time of diagnosis vs. 1st vs. 2nd vs. 3rd relapse. This study will provide insights into the immune status of MM patients before and after disease transformation and help identify patients who will benefit from immunotherapy. It will also allow us to predict the efficacy of these immune-mediated strategies and their associated toxicity. By understanding the immune-microenvironment in MM patients during disease progression, the investigator will be able to better design immunotherapeutic strategies for maximal success.

Background and Rational (Introduction) Differentiated thyroid carcinoma (DTC) have favorable prognosis. Overall 10-year survival is 93% for papillary carcinoma, and 85% for follicular carcinoma(1). After total thyroidectomy followed by radioiodine remnant ablation, DTC patients are screened for recurrence by measuring the levels of both Tg and TgAb and I-131 whole body scan (WBS) in the follow-up (2) It is reported that elevated TgAb may indicate the recurrent and/or metastatic disease and can be used as an alternative of the tumor marker for DTC . The I-131 WBS has high specificity to detect recurrence (50 to 60% in papillary thyroid carcinoma and 64 to 67% in follicular thyroid carcinoma) (3,4). The I-131WBS showed negative finding in 10 to 15% of patients with detectable serum Tg levels(5). Two factors may account for discrepancy between serum Tg and I-131 WBS . First, the tumor size might be too small to be detected by WBS. Second, the tumor cell may lose the ability to trap radioiodine while still able to secret Tg(6,7). It becomes necessary to investigate with other modalities to identify possible residual disease to initiate the appropriate treatment. (8) Positron emission tomography with 2-deoxy-2-[fluorine-18]fluoro- D-glucose integrated with computed tomography (18F-FDG PET/CT) has emerged as a powerful imaging tool for the detection of various cancers. (9) The combined acquisition of PET and CT has synergistic advantages over PET or CT alone and minimizes their individual limitations. (10) It is a valuable tool for staging and re staging of some tumors and has an important role in the detection of recurrence in asymptomatic patients with rising tumor marker levels and patients with negative or equivocal findings on conventional imaging techniques.(11) Aim of the study The aim of this study was to evaluate the diagnostic accuracy of (PET/CT) in patients with suspected thyroid cancer recurrence or metastasis , with differentiated thyroid cancer (DTC) patients who show elevated serum thyroglobulin (Tg) or antithyroglobulin antibody (TgAb) level with negative radioiodine whole body scan (I-WBS).

In France, as in most countries, the incidence of primary liver cancer has increased significantly since the 1980s. In the United States, a study estimating cancer incidence and mortality rates in the coming years predicts that primary liver cancer will become the 3rd leading cause of cancer death from 2030 onwards, behind lung and pancreatic cancer, but ahead of colorectal cancer. This increase in incidence could be explained on the one hand by an increase in the incidence of chronic liver diseases, particularly those related to alcohol and metabolic steatopathies in the West, and on the other hand by improved management of the consequences of cirrhotic disease, which in turn increases the time needed for hepatocellular carcinoma (HCC) to form and develop. The management of a patient with hepatocellular carcinoma is complex because of the underlying cirrhotic disease, which hinders the development of many therapies. Thus, the patient's prognosis depends as much on the tumour extension as on the severity of the underlying chronic liver disease, and the choice of appropriate treatment is based on optimizing the balance between maximum antitumor efficacy and limited liver toxicity. It is in this context that minimally invasive technical acts, whether local or local-regional, have developed significantly in recent years. Percutaneous tumor destruction techniques have become highly diversified with the development of microwave ablatherm, multipolar radiofrequency, or irreversible electroporation. For intra-arterial treatments, hepatic arterial chemoembolization remains the reference treatment for BCLC B stages. Alongside it, Yttrium 90 radio-embolization is booming, although its precise place remains to be defined in the therapeutic arsenal. Surgical techniques have also progressed, with the development of laparoscopic resections and improved liver transplant management. Finally, external radiotherapy is a recourse solution that can make it possible to propose a therapeutic solution in selected patients. This multidisciplinary management of the HCC is in constant evolution and improvement, which justifies regularly carrying out an inventory of the frequency of these various technical acts at the national level. The objective of our study is to analyze the evolution, over the last 10 years and at a national level, of the various technical procedures available in the HCC therapeutic arsenal based on data from the french national PMSI database.

The Institute of Image-Guided Surgery (IHU) of Strasbourg develops new minimally invasive therapies, the benefit of which is maximized by an integrated approach to the care pathway (pre, per and postoperative). Encouraging patient engagement in the process responds to its growing demand for information and consideration, enhances its care experience and clinical outcomes. Medtronic has designed an digital solution for patient engagement (current name: "Get Ready") for scheduled colorectal surgery. The IHU is a pilot experiment site for this solution. This research protocol, of which the IHU is the promoter, aims at evaluating the use and the impact of this solution made available to the patients of the Hepato-Digestive Pole (PHD) of the New Civil Hospital. The solution deployed at the Strasbourg IHU aims to improve the patient's preparation for his colorectal surgery and follow his rehabilitation after surgery, by reinforcing his compliance with existing protocols and enriching it with complementary practices. The solution is not a medical device. It is limited to advice, monitoring and restitution of data declared by the patient; it is not intended to prevent, diagnose or treat the pathology; it is independent of any other medical device. This study aims to assess the pre-operative impact of the solution, in terms of patients' adherence to the pre-operative program and correlations with their physical and psychological condition until their admission to surgery. The secondary purpose of the study is to precise the acceptability of the solution.

This study aims to explore the reliability of the combination of functional magnetic resonance imaging and radiomics for evaluation of the therapeutic efficacy of CyberKnife stereotactic radiosurgery for spinal tumors. Accurate imaging assessment can help clinicians plan personalized therapeutic schedules for patients with spinal tumors .

The CoNoR study aims to assess whether the use of the LiMAx test and the HepaT1ca pre-operative planning magnetic resonance scan impact upon technical resectability decision-making in colorectal liver metastases (CLM).

Prospective registry study of endoscopic submucosal injection of indocyanine green before laparoscopic radical resection for colorectal cancer

Known risk factors inducing squamous cell carcinomas of the head and neck are tabacco and alcohol intake. However, the incidence of human papillomavirus (HPV) related oropharyngeal carcinomas is increasing. It is known that HPV+ and HPV- tumors have a different reaction to (chemo)radiotherapy. The exact mechanisms underlying these differences is not yet known but might be caused by changes in vascularity. Therefore the vasculature is imaged with the help of a study specific Gallium-68-DOTA-(RGD)2 PET/CT scan and a CT perfusion scan.

Lung cancer is the most common cancer in China from both incidence and mortality rate point of view, with significantly lower 5-year survival rate than average. Early detection is the recognized solution. LDCT is more and more popular accepted as an effective screening methodology but leads to numerous indeterminate pulmonary nodules for physicians to distinguish too. The value of autoantibody test in risk assessing of IPNs as well as early detection of lung cancer in high risk population has been demonstrated in clinical practice and trial but mainly in Caucasian. Purpose of this study is to understand the sensitivity, specificity and accuracy of candidate autoantibodies, and consequently explore the autoantibody combination with best clinical performance in Chinese population.
