title: Tetracycline and quinacrine in the control of malignant pleural effusions. A randomized trial.
abstract: Eighteen patients with advanced metastatic malignancy who had 21 pleural effusions requiring sclerosis for control were randomly allocated to intrapleural therapy with tetracycline or quinacrine. Tetracycline produced partial or complete control of the effusion in ten of 12 trials for a median duration of 6 months (range 1.5 to 22 months). Partial or complete control was obtained in nine of ten trials with quinacrine, for a median duration of 3 months (range 1 to 13 months). All complete responders who died achieved control of their effusions until their terminal admissions despite clinical evidence of overt systemic tumor progression in the intervening period. Single-dose tetracycline therapy was accompanied by less fever (p less than 0.04) and less pleuritic pain (p = 0.09) than quinacrine. Tetracycline is effective, well tolerated, easily administered, and should be considered as the initial therapy for malignant pleural effusions requiring pleural sclerosis.
