Intrapleural bleomycin in the treatment of chylothorax.

Chylothorax is an accumulation of thoracic lymph or chyle in the pleural cavity. It is a rare condition and is usually caused by trauma or malignant disease. We present three cases with chylothorax due to malignant non-Hodgkin's lymphoma [high grade malignant (1 case) and low grade malignant (2 cases)] treated with pleurodesis with bleomycin and systemic chemotherapy (CHOP, CNOP, trofosfamide). Complete remissions (CR) were achieved in all three cases. Two patients had a recurrent chylothorax 3 and 12 months after initial treatment. They were treated with a second intrapleural installation of bleomycin and continuing systemic chemotherapy (CNOP, trofosfamide) and are still alive in CR with a follow-up period of 28 and 30 months respectively. One patient died of relapsing non-Hodgkin's lymphoma after 23 months of follow-up. There was no sign of recurrent chylothorax. We conclude that chylothorax caused by lymphoma can be satisfactorily controlled by pleurodesis with bleomycin combined with systemic chemotherapy. Immediate action is necessary to prevent great loss of lipids and proteins. The underlying malignancy must be controlled to achieve a good prognosis.
