Malignant Neoplasm of Bone and Articular Cartilage

Any time the words "you," "your," "I," or "me" appear, it is meant to apply to the potential participant. The goal of this clinical research study is to find the highest tolerable dose of gemcitabine that can be given by inhalation (breathing it as a mist) to patients with solid tumors that have spread to the lungs from other parts of the body. The safety and side effects of this drug will also be studied. This is an investigational study. Gemcitabine is FDA approved and commercially available for the treatment of pancreatic and lung cancer, and other solid tumors. Its administration by inhalation is investigational. The study doctor can explain how the study drug is designed to work. Up to 44 participants will be enrolled in this study. All will take part at MD Anderson.
