Summary |
Introduction |
Malignant pericardial effusion is a severe complication of lung and breast cancer. The median survival is less than 4 months and recurrences occurs in about 40% of cases. Systemic chemotherapy and/or local treatments are necessary, even if there is no consensus.
Methods |
We collected data from patients in our center from 1997 to 2016 who received at least one intrapericardial instillation of bleomycin (60mg). At the same time, we conducted a review of the relevant literature on the subject.
Results |
We included 46 patients in the analysis. Median survival was 2.6 months [95% CI: 1.7; 4.7]. Overall survival was 49% [33%; 63%] at 3 months and 28% [15%; 42%] at 6 months. In the lung cancer subgroup, overall survival was 18% [3%; 44%] at 3 months. In the breast cancer subgroup, overall survival was 73% [44%; 89%] at 3 months and 46% [21%; 69%] at 6 months.
Discussion |
The best response rates in the literature are obtained with local instillation of bleomycin or cisplatin. Malignant pericardial effusions in breast cancer patients had a better prognosis. This is certainly related to the prognosis of the underlying disease. We have not found an increase in overall survival with intrapericardial chemotherapy injections, but preventing recurrence of malignant pericardial effusions is a benefit in itself, thus avoiding a lethal complication.
