Determinants of Survival After Emergency Intrapericardial Cisplatin Treatment in Cancer Patients with Recurrent Hemodynamic Instability After Pericardiocentesis.

Background: Pericardial effusion is associated with high mortality in oncology. The etiology of infectious pericarditis and iatrogenic effects of previous radio/chemotherapy may be always suspected, especially when a subsequent episode is observed. Patients and Methods: The study included 17 hemodynamically-unstable patients with cancer due to recurrent pericardial bloody effusion after previous pericardiocentesis and analyzed survival determinants after intrapericardial chemotherapy with cisplatin. Results: The mortality rate was not significantly associated with the level of N-terminal pro-B type natriuretic peptide, low hemoglobin (<12 g/dl), elevated white blood cell account (>10(4)/mu l), large volume (>1500 ml) and long duration (>8 days) of pericardial drainage, cardiac arrhythmias, positive culture test results nor fever occurring during cisplatin administration. Subsequent systemic anticancer therapy was the strongest factor determining a longer survival (hazard ratio(HR)=0.31, 95% confidence interval(CI)=0.11-0.9; p=0.03). Conclusion: Efficacy of rescue intrapericardial chemotherapy with cisplatin is independent of parameters of hemodynamic instability and levels of inflammatory markers in recurrent pericardial effusion.
