Stopped: Slow/Insufficient accrual
Background: Mithramycin is a new cancer drug. In another study, people with chest cancer took the drug 6 hours a day for 7 straight days. Many of them had liver damage as a side effect. It was discovered that only people with certain genes got this side effect. Researchers want to test mithramycin in people who do not have those certain genes. Objectives: To find the highest safe dose of mithramycin that can be given to people with chest cancer who have certain genes over 24 hours instead of spread out over a longer period of time. To see if mithramycin given as a 24-hour infusion shrinks tumors. Eligibility: People ages 18 and older who have chest cancer that is not shrinking with known therapies, and whose genes will limit the chance of liver damage from mithramycin Design: Participants will be screened with: * Medical history * Physical exam * Blood and urine tests * Lung and heart function tests * X-rays or scans of their tumor * Liver ultrasound * Tumor biopsy * Participants will be admitted to the hospital overnight. A small plastic tube (catheter) will be inserted in the arm or chest. They will get mithramycin through the catheter over about 24 hours. * If they do not have bad side effects or their cancer does not worsen, they can repeat the treatment every 14 days. * Participants will have multiple visits for each treatment cycle. These include repeats of certain screening tests. * After stopping treatment, participants will have weekly visits until they recover from any side effects.
