Active clinical trials for "Carcinoma"

This is a non-interventional study to observe the safety and efficiency of chemotherapy for potentially resectable locally advanced esophagogastric junction

The purpose of this study is to observe predictors of pituitary tumor recurrence and markers of persistent disease activity through computerized collection of comprehensive demographic, therapeutic, pathologic and outcome information on patients harboring pituitary mass lesions of all types.

The purpose of this study is to establish molecular subtyping of HCC.

The purpose of this research study is to examine the relationship between the microbiota (microscopic organisms) in the gut and the activity of the immune system during skin cancer immunotherapy.

Hepatocellular carcinoma (HCC) is the most common type of liver cancer, its survival rate ranks only second to lung cancer and it is a severe threat to human health. In Egypt, HCC constitutes a significant public health problem. Where it is responsible for 33.63% and 13.54% of all cancers in males and females respectively. It has a poor prognosis after discovery, which is usually at a late stage of disease. This had been strongly linked to the hepatitis C virus epidemic that affected around 10-15% of the Egyptian population during the last 3 decades, and was reported as the highest prevalence of HCV in the world. However, the pathophysiological mechanisms involved remain unclear. The occurrence of HCC is a complicated process involving multiple genes and steps. Imbalances in cellular signal transduction pathways, deficiencies in DNA repair regulating genes, activation of protooncogenes, inactivation of tumor suppressor genes and epigenetic modifications all promote the occurrence of liver cancer.

It is a a single arm, observational clinical trial to evaluate the efficacy and safety of combination treatment with sintilimab injection plus endostar in untreated locally advanced or metastatic hepatocellular carcinoma.

Hypoxia imaging has not been studied extensively by combining PET and MRI data. Few studies performed the double imaging and none associated anatomopathology with it . This study will use a rigorous methodology through the production of PET/MRI images at the same time by transferring the patient directly from PET to MRI. In addition, the population, unlike other studies, will include preoperative patients with 24-hour surgery for hypoxia imaging by obtaining additional data through specific immunohistochemical analysis of hypoxia.

It is proposed to undertake a study to determine the diagnostic utility of using RCM for the diagnosis of Basal Cell Carcinoma (BCC) in a tertiary referral centre as outlined by the recent NICE report (Nov 2015). This will allow an assessment of the potential to avoid diagnostic biopsy within the treatment pathway.

This project is a pilot study to interrogate the potential of LMS as a predictive tool for the selection of therapy for HCC patients. The reliability of LMS to predict patients' response following HCC therapy will leverage on an algorithm that is built from the pool of MRI scans from HCC patients pre- and post-treatment. In the study, MRI scans of 30 HCC and metastatic colorectal cancer (CM) patients (ratio of 4:1) will be analysed. CM cancer patients include patients whose cancers metastasized from colorectal cancer or primary liver cancer. These patients will either receive one of the treatment, surgical resection, Y90 or systemic therapy. A total of 4 MRI scans will be taken for each patient; the first MRI scan will be taken within a month before treatment initiation and the remaining MRI scans will be taken at the 1st, 3rd and 9th month post-initiation of treatment.

The investigators retrospective collect the clinical data of patients diagnosed with lymphoepithelioma-like carcinoma, including primary site, gender, age, smoking history, tumor stage, time of initial treatment, EBV-DNA copy number, first-line treatment and survival status.
