PURPOSE: Malignant pericardial effusion, although highly variable, is an
uncommon complication of cancer. It is often associated with symptoms like
dyspnea, chest pain, and cough, which may be severe and disabling. We
analyzed the results of our current treatment policy to evaluate the
effectiveness and tolerance of a new approach for this disorder. PATIENTS
AND METHODS: Patients with malignant pericardial effusions were treated
with intracavitary thiotepa (15 mg on days 1, 3, and 5) through an
indwelling pericardial cannula after extraction of as much pericardial
fluid as possible on day 0. Responses were assessed by clinical
examination, computed tomographic (CT) scan, and echocardiography before
treatment, 1 month after treatment, and every 2 months thereafter.
Twenty-three patients with malignant symptomatic pericardial effusion were
treated and all were assessable for effectiveness and tolerance of the
procedure. RESULTS: Nine patients with breast cancer, 11 with lung cancer,
two with an unknown primary tumor, and one with metastatic melanoma were
treated. In all but three patients, systemic medical treatment was started
after completion of intracavitary therapy. Nineteen patients responded to
treatment (83%; 95% confidence interval, 61% to 95%) with a rapid
improvement of symptoms. The median time to pericardial effusion
progression was 8.9 months (range, 1 to 26). No significant side effects
were registered, except one patient who had transient grade III
thrombocytopenia and leukopenia and one patient who had grade I leukopenia.
CONCLUSION: A short course of intracavitary treatment with thiotepa is
highly effective and well tolerated in the treatment of malignant
pericardial effusion.
