Active clinical trials for "Carcinoma"

Background: X-ray mammography is the standard method for breast cancer screening. It is a noninvasive test using x-rays to take pictures of breast tissue and detect any abnormalities. The National Institutes of Health (NIH) Clinical Center has a breast imaging unit that has been accredited by the American College of Radiology. To maintain accreditation, the unit must recruit a certain number of women to have clinical mammograms each year in order to maintain a high level of clinical skills and experience for the radiologists and technologists. Objectives: - To create a state-of-the-art mammography unit at the NIH Clinical Center in order to maintain American College of Radiology accreditation of the NIH breast imaging facility. Eligibility: - Women who are eligible for breast cancer screening because of family cancer history, genetic test results, or previous instances of cancer. Participants may not be pregnant or nursing at the time of the screening. Design: Participants will provide a brief medical history on arrival at the NIH breast imaging unit. Each participant will have a standard mammogram performed by a radiology technician. If the study is normal, participants will be told that no further evaluation will be performed. If the results indicate a need for further imaging or tissue biopsy, participants may elect to return to the care of their primary physician or to receive further follow-up at the NIH Clinical Center.

Hepatocellular carcinoma is an aggressive disease with limited therapeutic options. Therefore, new approaches to treat this type of cancer are needed with immunotherapy potentially being one of these. As a first step in the development of novel therapies, expression analysis of specific markers, including tumor antigens will be carried out. This will be done retrospectively using available hepatocellular carcinoma tissue samples.

The purpose of this study is to evaluate 3 imaging techniques and their associations : MRI, CTscanner and enhanced contrast ultrasound for the diagnosis of small (< 3 cm) hepatocellular carcinoma for patients with cirrhosis.

This is an interdisciplinary study that falls into the Humanitarian Use Device category. There are no hypotheses to be tested in this treatment protocol. The study has the following objectives: Provide supervised access to treatment with TheraSphere® to eligible patients with primary cancer to the liver who are not surgical resection candidates. Evaluate patient experience and toxicities associated with TheraSphere® treatment. Measure tumor response rates

This is an epidemiological, prospective, multicenter study designed to identify the pre-treatment clinical, molecular and genetic prognostic factors associated with progression free survival in patients naïve to renal cell carcinoma (RCC) treatment.

The objective of this study is to record recurrence in patients treated for nonmelanoma (basal cell and squamous cell carcinomas) skin cancer using the Xoft Axxent Electronic Brachytherapy System. Additional objectives include evaluate the appearance of the treated area in patients treated for nonmelanoma skin cancer using the Xoft Axxent Electronic Brachytherapy System and record the occurrence of radiation therapy related skin changes in patients treated for nonmelanoma skin cancer.

The objective of the study is to determine whether a specific immune microenvironment in the primary tumor is associated with a favorable clinical course after nephrectomy and in the absence of adjuvant treatment.

A registry of patients with the diagnosis of hepatocellular carcinoma.

To study changes in tumor and normal organ size and/or position which occur during a course of radiation treatments.

This study is to compare the ability of optical biopsy. Research can use light enters the skin, collected, analyzed by the computer, and a picture created for the pathologist to conventional histologic examination compare with the pathologist looking at the piece of tissue through a microscope makes the diagnosis.
