Active clinical trials for "Carcinoma"

Estimation of functional liver reserve in patients with hepatocellular carcinoma (HCC) in cirrhosis is of paramount importance to properly select candidates for surgical resection. Together with the value of bilirubin, the presence/absence of ascites and esophageal varices, and the rate of residual liver volume, which are our current parameters to measure functional liver reserve, the investigators sought to investigate the value of preoperative cholinesterases (CHE) in predict postoperative adverse outcome after hepatic resection for HCC.

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.

The purpose of this study is to estimate and define the mean number, degree of confluence, and depth of penetration of melanocytes in chronically sun exposed skin of the head and neck using Mart-1 immunostains on frozen sections. The study was conducted to confirm whether similar results were found using permanent sections. The present study used hematoxaline and eosin (H&E) staining as well as Mart-1 staining, and included patients from both Mayo Clinic Jacksonville and Rochester.

The purpose of this study is to image skin and skin lesions with a new imaging technology called "multiwavelength and coherence confocal reflectance microscopy". This technology uses low intensity laser to image below the surface of the skin. This technology may provide a new way of looking at skin and skin lesions. The goal of this study is to evaluate the images of your skin taken by this microscope. The techniques being evaluated in this study use multi wavelength and coherence confocal reflectance microscopy invivo. The term "in vivo" means in/on a living subject. In this study you will be the living subject and the multi wave length and coherence confocal microscope will be placed on your skin to look at your skin lesions and your normal skin. The confocal microscope uses a weak laser light and a sophisticated lens to image the individual cells that make up the skin. Your lesion will be photographed with high resolution photography. An area near your skin lesion that is clinically normal will also be imaged in the same manner.

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.

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.

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.

Forty patients with advanced pancreatic cancer, osteosarcoma, soft tissue sarcoma, and breast cancer will receive DeltaRex-G intravenously at a dose of 1-4 x 10e11 colony forming units (cfu) or equivalent 0.6-1.8 x 10e10 RV copies per dose one to three times a week. DeltaRex-G may or may not be given with one or more FDA approved cancer therapies/immunotherapies. Based on previous Phase 1/2 US based clinical studies, DeltaRex-G does not suppress the bone marrow or cause serious organ dysfunction, and enhanced immune cell trafficking in tumors may cause the tumors to appear larger or new lesions to appear on CT, PET or MRI. Further, tumor stabilization/regression/remission may occur later during the treatment period. Therefore, DeltaRex-G will be continued regardless of CT, PET or MRI results if the patient has clinical benefit and does not have symptomatic disease progression.
