Active clinical trials for "Carcinoma"

The purpose of this registry is to record information of therapy reality of metastatic or locally advanced Renal Cell Carcinoma by office-based medical oncologists in Germany.

In this study, renal cell carcinoma (RCC) related miRNA and the target genes of related miRNA will be examined in order to investigate the role of miRNA in the formation of RCC and look for the biomarker of RCC.

This is a multicentric feasibility study aimed to evaluate the Oncoral® test. The study includes 2 steps. The first one aims to validate the algorithm defined at the time when the test was developed in patients with different tumour stages. Patients will be enrolled before any treatment. They will immediately undergo the test. No follow-up will be realized. In total, 100 patients will be included in this first step. The estimated period of inclusion is 6 months. If the algorithm is validated, the second step of the study will start. The purpose is to determine the characteristics of the test. Enrollment will concern smokers and alcohol drinkers at high risk of developing an epidermoid carcinoma of the upper aerodigestive tract. Patient follow-up will vary with both the result of the test and the biopsy, up to a maximum of one year. In total, 385 patients will be enrolled in this step during an estimated period of 18 months.

Results of liver transplantation, the best theoretical treatment for HCC, are limited by tumor recurrence. In order to limit this risk Milan criteria was proposed in 1996. However, these criteria are to restrictive and approximately 40% of patients denied by Milan criteria may be cured by liver transplantation. The purpose of this study was thus to prospectively evaluate factors predicting tumor recurrence after liver transplantation for HCC and then to reassess criteria for liver transplantation.

Background: Esophageal cancer is the sixth leading cause of cancer deaths worldwide. Two primary cell types, squamous cell carcinoma and adenocarcinoma, account for most cases. Of the two, esophageal squamous cell carcinoma (ESCC) accounts for more than 80 percent of all deaths from esophageal cancer. Many cases occur in certain areas with defined geographic boundaries, including parts of Kenya. Studies of ESCC in developed countries (such as the United States) suggest that heavy tobacco and alcohol use, poor diet, and low socioeconomic status are the primary risk factors. Males and African Americans are also at higher risk. However, these risk factors do not fully explain the prevalence of cases in several of the identified geographic areas. ESCC is the most common cancer seen at Tenwek Hospital in western Kenya, and a notable number of patients are 30 years of age or younger. Objectives: To test the feasibility of a new protocol by recruiting visitors to Tenwek Hospital and volunteers from the general population for study purposes. To use the new protocol to obtain blood and urine samples from ESCC cases in Tenwek Hospital and from nonpatient volunteers. Eligibility: Hospital patients and volunteers who live within 50 kilometers of Tenwek Hospital in western Kenya. Design: All participants will complete a questionnaire and provide blood and urine samples for testing. The questionnaire will include questions about individual and family medical history, living conditions, lifestyle, habits, and diet. Blood and urine samples will be collected from all participants after the questionnaire. Biological samples will be shipped to the United States for further testing. Treatment will not be offered as part of this study.

To explore biomarkers predictive of clinical response to sorafenib in unresectable hepatocellular carcinoma using the Prometheus Platform To analyze expression and activation status of receptor tyrosine kinases in signal transduction pathways in FNA samples and circulating tumor cells. To identify negative predictive markers to sorafenib. To elucidate signal transduction pathway attributable to sorafenib resistance. To monitor changes in the RTK activation status during sorafenib treatment using circulating tumor cells. To analyze correlation between the quantity of circulating tumor cells and circulating endothelial cell precursors and treatment response to sorafenib.

This is a single arm study with axitinib in patients with advanced kidney cancer (clear cell variant), who have failed first line therapy. The study will recruit a maximum of 30 patients from 2 countries including Australia and Canada. Patients will be followed up for efficacy, safety and health related outcomes.

This is an open-label, exploratory, biomarker study of intravenous temsirolimus given once weekly for 3 weeks to newly diagnosed, advanced stage head and neck cancer subjects prior to beginning their standard therapy for their specific disease. The primary objective of this study is to identify biomarkers of temsirolimus activity.

The purpose of this study is to learn more about the metabolic properties of lung cancer cells.

Hepatocellular carcinoma (HCC) is the most common form of liver cancer and its incidence is increasing including in regions where hepatitis infection rates are low. This trend may be the result of increases in 'unhealthy lifestyle' factors. The main aim of this study is to identify metabolic signatures associated with healthy lifestyle behaviours and to relate these signatures to risk of developing HCC to investigate whether the metabolites were of predictive utility for HCC beyond data procured from questionnaires. To address this question, we exploited data from a large European cohort (EPIC) which includes detailed questionnaire-based data as well as metabolomic data.
