Malignant pleuraleffusion (MPE) refers to the pleural effusion caused by the involvement of pleural or pleural primary tumors in lung cancer or other malignant tumors and is a common complication of advanced malignancies. It is generally believed that MPE accounts for about 25% of the total pleural effusion. It is estimated that 75% of MPE is caused by lung cancer and breast cancer while the remaining 25% is caused by other neoplastic diseases [1].
