Radical Pleurectomy/Decortication (PD) and Intensity Modulated Radiotherapy (IMRT)

2014-07-24 14:01:10 | BioPortfolio

Summary

The goal of this clinical research study is to find the highest tolerable dose of radiation that can be given to directly to the pleura (the outer lining of the lungs) using intensity modulated radiation therapy (IMRT) in patients with malignant mesothelioma (MM) who have had a pleurectomy.

Description

IMRT:

IMRT is a technique to deliver radiation that allows the radiation beam to be shaped around the target area.

Radiation Dose Levels:

If you are found to be eligible to take part in this study, you will be assigned to receive one of two doses of radiation therapy based on when you joined the study. If the first dose is tolerated well by the first group of participants in this study, then the next group of participants will receive the second, higher dose of radiation.

Practice Visit:

You will have a practice radiation visit about 6-14 weeks after your surgery. At this visit, you will have a computed tomography (CT) scan that will be used by the study staff to target where you will receive the IMRT.

A mold will also be made around your body and marks will be made on your skin to help position your body correctly for the IMRT. This practice visit should take about 1-2 hours.

IMRT Visits:

Two (2) weeks after the practice radiation visit, you will begin receiving IMRT. At each visit, you will lie down in the mold of your body that was made at the practice visit and you will be lined up for the IMRT using the marks made at the practice visit. The IMRT will then be delivered. You will receive IMRT every weekday (Monday-Friday) for up to 5 weeks. These visits should last about 45-60 minutes.

Study Visits:

The following tests and procedures will be performed 1 time every week for up to 5 weeks while you are on study:

- You will have a physical and skin exam.

- You will have lung function tests.

You will also have a chest x-ray during the last week that you are receiving IMRT.

Length of Study:

You may receive IMRT for up to 5 weeks. The IMRT will be stopped early if the disease gets worse or intolerable side effects occur.

Follow-up Visits:

One (1) month after your last dose of IMRT, you will have a chest x-ray, lung function tests, and physical exam.

Two (2) months after your last dose of IMRT, you will have a chest x-ray and physical exam.

Three (3) months after your last dose of IMRT, you will have a chest x-ray, lung function tests, a physical exam, and a CT scan of your chest.

Long-term Follow-up:

Every 3 months for 2 years, every 6 months for the next 3 years, and 1 time every year after that, you will have lung function tests, a physical exam, and alternating CT and positron emission tomography (PET) scans to check the status of the disease. This means that if you have a CT scan at one visit, you will have a PET scan at the next visit, or vice versa.

This is an investigational study. IMRT given directly to the pleura in patients with MM after a pleurectomy is currently being used for research purposes only.

Up to 22 patients will take part in this study. All will be enrolled at M. D. Anderson.

Medical and Biotech [MESH] Definitions

Tumors or cancer of the LUNG.

Malignant neoplasm arising from the epithelium of the BRONCHI. It represents a large group of epithelial lung malignancies which can be divided into two clinical groups: SMALL CELL LUNG CANCER and NON-SMALL-CELL LUNG CARCINOMA.

Nuclear phosphoprotein encoded by the p53 gene (GENES, P53) whose normal function is to control CELL PROLIFERATION and APOPTOSIS. A mutant or absent p53 protein has been found in LEUKEMIA; OSTEOSARCOMA; LUNG CANCER; and COLORECTAL CANCER.

A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA. They are dealt with collectively because of their shared treatment strategy.

A form of highly malignant lung cancer that is composed of small ovoid cells (SMALL CELL CARCINOMA).
