Effects of intrapericardial administration after catheter drainage on malignant pericardial effusion in non‐small cell lung cancer: A real‐world study
Abstract
Abstract Background Malignant pericardial effusion (MPE) is a serious complication of cancer that can be potentially deadly. It usually occurs in advanced or terminal stages of the disease, and as a result, patients with MPE often have a poor prognosis. There is a limited amount of research available that directly compares the effectiveness and safety of intrapericardial drug administration following pericardial drainage versus catheter drainage alone in non‐small cell lung cancer (NSCLC) patients who have MPE. Methods We retrospectively included 86 patients with NSCLC with MPE at Zhejiang Cancer Hospital. Survival and recurrence estimates were determined with the Kaplan–Meier method. Results We divided the 86 patients with NSCLC into two groups: a pericardial drainage group (34 out of 86, 39.5%) and an intrapericardial administration group (52 out of 86, 60.5%). The response rates were 70.6% and 76.9% (p = 0.510), respectively. The median OS was 132.0 and 234.0 days (p = 0.579), respectively. The median time to recurrent drainage was 43.0 and 104.0 days (p = 0.170), respectively. The incidence of adverse events (AEs) was 44.1% and 61.5% (p = 0.113), respectively. The most frequent AEs were pain (27.9%) and fever (24.4%). Additionally, two patients in the intrapericardial administration group died of cardiac arrest. Conclusions Compared with catheter drainage alone, intrapericardial medication infusion during catheter drainage did not have significantly different effects. AEs require close monitoring and management.
