PRIMARY OBJECTIVE:
I. To evaluate dyspnea using the visual analog scale (VAS) scale at one week in patients with symptomatic septated malignant neoplasm of the pleural effusion (MPE) and a non-draining/inadequately draining indwelling pleural catheter (IPC).
SECONDARY OBJECTIVE:
I. To evaluate dyspnea using the visual analog scale (VAS) scale at 48 hours (+/-12 hours) after treatment with intrapleural alteplase, in patients with septated MPE and a nondraining/inadequately draining IPC. In addition, complications, quality adjusted survival (calculated using the SF-6D to determine utilities and then integrating utilities over time to arrive at quality-adjusted survival), change in dyspnea (using the Borg score and VAS scale) at 1 week (+/- 1 day), 2 weeks (+/- 2 days) and every 4 weeks (+/- 2 days) after the intervention until IPC removal or death.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive alteplase instilled into the IPC which is capped for 1-2 hours before the catheter is drained.
ARM II: Patients receive placebo instilled into the IPC which is capped for 1-2 hours before the catheter is drained. Beginning 1 week later, patients may receive alteplase as in arm I.
