Active clinical trials for "Carcinoma"

Specific urine proteases or groups of these enzymes can be reliable biomarkers and an effective gauge of response to therapy in patients with hepatocellular carcinoma.

The principal objective of the study is to evaluate the efficacy and safety of temsirolimus use in patients with Renal Cell Carcinoma and Mantle Cell Lymphoma.

Objective of this study is to increase knowledge about safety, tolerability, quality of life and efficacy under conditions of routine use of sunitinib.

Background: Resistance to cancer chemotherapy develops in patients, rendering certain treatments ineffective. Despite much research, the prevailing cause of drug resistance is not known. One mechanism for drug resistance involves a protein called P-glycoprotein, or Pgp, which reduces the effectiveness of cancer treatments by "pumping" anti-cancer drugs out of tumor cells where they are supposed to work against the disease. Objectives: To identify and evaluate more thoroughly the roles of Pgp and other substances in mediating drug resistance. Eligibility: Patients enrolled in clinical trials of cancer therapies at the Children's Hospital of Pittsburgh; Cancer Centers of Carolinas; Arizona Clinical Research Center; University of Copenhagen; and Herlev Hospital, Copenhagen who have consented to the use of blood, tissue, or tumor samples for laboratory studies. Design: Blood, tumor, and tissue samples are collected from participants and sent to the NCI for various laboratory analyses. ...

In this international non-interventional study safety and clinical data concerning the treatment of patients suffering from Hepatocellular Carcinoma (HCC) will be collected.

Polymorphisms of HSP70 and tumor necrosis factor-alpha promoter in patients with hepatocellular carcinoma, chronic liver disease and healthy controls will be measured by PCR-RFLP or direct sequencing. The clinical relevance of patients will be compared in those with polymorphism and those without.

The goal is to study the impact of functional MRI and CT evaluation of changes in tumor vessels induced by anti-angiogenic treatment in patients with metastatic RCC. The hypothesis is that good responders and poor responders will have different responses induced by anti-angiogenic treatment, and that the detection of theses changes by functional imaging can improve the therapeutic management. Functional CT and MRI will be performed in 200 patients before the beginning of antiangiogenic treatment, 7 days after and every 6 week until tumor progression (as defined by the RECIST criteria). Perfusion and diffusion parameters will be measured using a dedicated software.

Hepatocellular carcinoma (HCC) is the most common malignant tumor of the liver. Transcatheter arterial chemoembolization (TACE) is the traditional method for the palliative management of patients with HCC. Few previous studies had demonstrated that the serum level of anticancer drug from patients treated by TACE was similar to those treated by systemic chemotherapy. The defense ability of the patient treated by TACE may thus be influenced by the leakage of anticancer drug to the systemic circulation. Since more than 80% patients with HCC also have liver cirrhosis, the toxicity for those anticancer drugs with hepatic transformation will be increased caused by the cirrhotic liver. The severity of pancytopenia in cirrhosis will be exacerbated by the effect of bone marrow suppression caused by anticancer drugs. Patients are at high risk for infection and hemorrhage. Therefore, it is of clinical importance to prevent or decrease the leakage of anticancer drugs to systemic circulation in patients treated by TACE. The procedures of TACE performed by previous studies were not constant and the distributions of tumor vessels were not evaluated in detail. The possible risk factors for the leakage of anticancer drug have not been investigated. This project will collect 60 patients with HCC including 30 patients with hepatitis B and 30 patients with hepatitis C. The blood levels of anticancer drugs (epirubicin, mitomycin C and cisplatin) will be determined within one hour and at the third day after TACE.

This randomized phase III trial studies whether changes in diet and physical activity can increase the length of survival without the return of cancer (progression-free survival) compared with usual care in patients with previously treated stage II, III, or IV ovarian, fallopian tube, or primary peritoneal cancer. A healthy diet and physical activity program and counseling may help patients make healthier lifestyle choices. It is not yet known whether changes in diet and exercise may help increase progression-free survival in patients with previously treated cancer.

Primary objective: to increase knowledge about safety, tolerability, quality of life and efficacy under conditions of routine use of SUTENT®. Secondary objectives: treatment response, hypothyroidism prevalence.The efficacy will be assessed using the Objective Response Rate, Time to Progression based on the RECIST criteria and the ECOG performance data.
