Background: -Malignant ascites or pleural effusions are often seen in patients with solid tumor malignancies. -Malignant ascites is proinflammatory with many cytokines present and acts to promote tumor cell growth. -The cellular composition of malignant ascites consists of lymphocytes, macrophages and monocytes. -Serum monocytes and lymphocytes play a role in the native host anti-tumor immune mediated mechanisms. -A paracentesis or thoracentesis is often done for symptomatic relief from the malignant fluid collection. Primary Objective: -To obtain blood samples and ascites and pleural effusion samples from patients with solid tumor malignancies, with the intent of performing translational studies related to cancer. Eligibility: Patients greater than or equal to 18 years of age. Diagnosis of malignant solid tumor. Patients must be able and willing to provide informed consent. Design: -We will collect approximately 200cc-5L ascites from patients that are undergoing a therapeutic paracentesis or thoracentesis. No thoracentesis or paracentesis will be performed solely for research purposes. -The fluid will be collected during the medical procedure and may be collected at more than one time point. -We will also collect 30ml of peripheral blood. This will be from patients who are being seen in follow up, consultation, or presenting for enrollment on a clinical trial.
