Active clinical trials for "Neoplasms"

Radiotherapy plays an important role in multidisciplinary treatment of esophageal cancer. However, about half patients received radiotherapy occurred relapse. Once relapse occurred, there is no better treatment strategy. Genomic study of relapsed esophageal cancer is seldom. So the investigators attempt to collect relapsed tissue to conduct with whole exome sequencing in order to investigate the genome landscape of recurrence esophageal cancer.

The purpose of this trial is to study the relationship between the angiogenic response to surgical aggression, determined through the serum levels of vascular endothelial growth factor (VEGF) on postoperative day four, and the tumor recurrence in patients with colon cancer operated with a curative intention.

Skull base tumors are a type of tumor that grow in the area of several skulls behind the cranial cavity. The incidence rate is 2 to 18 per 100,000 people per year; males and females are likely to have a proportional difference in the types of skull base tumors. Cerebellopontine angle (CPA) tumors are the most common neoplasms in the posterior skull base,accounting for 5-10% of skull base tumors.Some different kinds of tumors can grow in cerebellopontine angle. The tumors are more likely to cause some symptoms when they grow large enough to put pressure on the brain. A common traditional treatment for skull base tumors is neurosurgery-craniotomy. However, after the operation, brain may be injured with hematoma, and the instruments used are in contact with the brain. It is still inevitable that there will have complications of minor and major nerve damages, such as facial paralysis,trigeminal neuralgia, tinnitus, sports disorders (ataxia) and so on. Acupuncture has a unique effect on the treatment of the human nervous system. Aim of the study is used acupuncture to improve the complications of the surgery of Cerebellopontine angle tumors in skull base.

This study was a prospective, single-arm, multi-channel, multicenter, non-interventional real-world study to evaluate the safety and efficacy of Toripalimab injection in the treatment of unresectable or metastatic melanoma with previously systemic failure . The study population currently included only in the melanoma cohort-unresectable or metastatic melanoma patients who had previously failed systemic therapy. If new indications are approved during the implementation of the project, patients with new indications using Toripalimab injection will also be included in this study as a new cohort.This study uses offline (physical hospital) and online (DTP pharmacy and Lingke (Yinchuan) Internet hospital) to collect data and information, relying on Lingke technology (Beijing) Co., Ltd. EDC (Medical Research Cloud) database for data collection and processing. The classification of adverse events was based on the general toxicity evaluation standard NCI CTCAE 5.0 of the National Institute of Oncology (Chinese version).

PubMed, ScienceDirect, Cochrane Database of Systematic Reviews will be used to search for articles published from January 1965 to July 2019 using the key words "renal cancer", "lymphocyte to monocyte ratio" and "prognosis". No restrictions to date, language, or article type will be applied. Cohort or observational studies in patients with non-metastatic renal cell carcinoma histopathologically confirmed, with hazard ratios (HR) and corresponding 95% confidence intervals (CI) that assessed association between LMR and overall survival (OS), cancer-specific survival (CSS), recurrence-free survival (RFS), and disease-free survival (DFS) will be analyzed.

Combination treatment with antiangiogenic agents and anti-programmed cell death protein 1 (PD-1) antibodies have shown high anti-tumor efficacy for patients with unresectable or advanced hepatocellular carcinoma (uHCC). In this single-center cohort study, we are aiming to (1) evaluate the clinical effectiveness in real-world patients, especially for Chinese patients, most of whom were with hepatitis B virus infection; (2) predict clinical effectiveness with clinicopathological features; (3) predict clinical effectiveness with histologic features and blood samples.

BACKGROUND: Hepatocellular carcinoma is the fifth most frequent cancer in the world, with a diagnosis of more than 500,000 new cases per year. It is considered the third leading cause of cancer mortality and presents well-defined risk factors. Liver cirrhosis is the main risk factor for developing HCC, therefore screening programs in cirrhotic patients will allow the early diagnosis of this neoplasia. Despite this, most HCCs are diagnosed at a stage in which the application of curative therapies is no longer possible. Hepatic transarterial chemoembolization (TACE) belongs to the arterially directed embolization therapies for the treatment of unresectable early-to-advanced hepatocellular carcinoma (HCC). It is the only therapy that has shown to improve survival in intermediate-stage HCC. Drug-eluting beads (DEB)-TACE has shown to provide slow drug elution, reduced liver and systemic toxicity, increased local drug concentration, and tissue necrosis. Aside from TACE, other transarterial options include bland embolization, or hepatic artery embolization (HAE), and transarterial radioembolization (TARE). All have an acceptable safety profile, and each has its associated procedural and peri-procedural complications. One potential complication that may occur during all embolization procedures is when the embolic material migrates outside of the desired treatment area, leading to non-target embolization (NTE). In fact, when collateral vessels are embolized, there is a risk that these may be feeders of non-target tissue or organs. NTE following TACE in particular may lead to a double-layer problem: dangerous components affecting healthy tissue, one ischemic and one related to cytotoxicity from the chemotherapeutic agent, which may have clinical consequences, and potential incomplete treatment of the lesion (due to beads being "deviated" from target). NTE is highly recognized, but often thought to be uncommon, and although different complications can be caused by it, there may appear to be no evidence of NTE during the intraprocedural imaging. To avoid the complications due to NTE, apart from the importance of the pre-, intra- and post-procedural imaging, and the thorough study of the anatomical picture, the catheters/microcatheters should also be chosen with reason and care. In particular, selective catheterization should be achieved by placing the microcatheter tip as close as possible to the target, through the specific branch/branches supplying it. However, even with the microcatheter selectively positioned in the vessel to be embolized, the risk of NTE might not be eliminated, since it could happen as a result of changes in flow dynamics that occur during embolization, particularly when the endpoint is stasis. These changes could result in reflux into non-target territories and, as such, might be better prevented with the use of microcatheters intended to reduce reflux. To this purpose, the use of a dedicated delivery device should be taken into consideration, in order to optimize and save time during the procedure. Microcatheters are commonly used during most arterial embolization procedures, and as explained above, there is a strong rationale to use a reflux-control microcatheter - like Sequre - for DEB-TACE. The main expectation is to achieve technical success with Sequre in all patients with a reachable target lesion, with the intent not only to minimize potential damage to surrounding tissue, but also to potentially deliver more treatment embolics, as all the beads are (re)directed towards the target. The use of small diameter particles (100 micron-TANDEM ® spheres), induces superior tumor necrosis response (Urbano et al., European Journal of Radiology, 2020); with the synergistic effect of being administered through the SEQURE anti-reflux protection system, there is reason to believe that it will be possible to administer maximum doses of doxorubicin, while avoiding the occlusion of non-target arterial segments (SYNERGIC EFFECT). STUDY PROPOSAL: We propose a prospective observational study with data collection from a single center (Virgen de las Nieves University Hospital-Granada), for a period that ranges October 2020-December 2021.

The aim of the present study is to assess the post-operative outcomes (morbidity and mortality) in relation to preoperative data and the oncological outcomes (overall and disease-free survival) in patients with a locally advanced colon cancer (LACC) with the necessity of a multivisceral resection (MVR).

To evaluate the feasibility and safety of laparoscopic colectomy and anterior resection for patients with colon/upper rectal cancer (CuRC) in day surgery center. Patients with colon or upper rectal cancer who meet the standards of day surgery will be enrolled, and laparoscopic radical resection of tumor will be performed in day surgery center. Perioperative outcomes of these patients and reasons for transferring to inpatient ward will be recorded prospectively.

This study aims to determine if there is any difference in the efficacy of radiotherapy for glioma outcomes in the morning or in the evening. The study team believes that there may be a benefit to taking the radiotherapy at a certain time of day. To test this theory the study asks participants who are already taking radiotherapy for glioma consistently at either the morning or in the evening based on when they currently take their radiotherapy. There will be this study visits where the participant will be asked to fill in questionnaires related to their neurological symptoms, their sleep habits, sleep quality, survival situation, and general health information followed by a blood draw.
