Colchicine: an effective treatment for refractory malignant pericardial effusion

We report a patient with AL amyloidosis and chemo-resistant light-chain multiple myeloma who developed a progressive malignant pericardial effusion leading to cardiac tamponade. Despite pericardiocentesis and surgical intervention, the pericardial effusion failed to resolve. The administration of oral colchicine produced symptomatic relief within 5 days, with the resolution of pericardial effusion after 14 days of treatment. As the administration of colchicine is simple and the side-effect is usually minimal, further studies are warranted to establish the feasibility of using colchicine to treat malignant pericardial effusion.
