Sažetak
Summary
Malignant pleural mesothelioma (MPM) is an aggressive tumor that develops from the mesothelial cells lining the pleural cavity. The most relevant risk factor is asbestos exposure. Despite therapy the median survival is poor ranging from four to 18 months. The aims and objectives of this study were to assess the clinical characteristics and survival of patients with MPM treated at UHC Zagreb. This study included 101 patients diagnosed and treated for MPM at UHC Zagreb from September 1999 to September 2012. We analyzed the overall survival (OS), progression free survival (PFS) and OS depending on histological subtype, clinical stage, age, treatment method and pleurodesis performed using the Kaplan-Meier method. Eighty-nine patients were male and 12 female with the median age of 62 years. Using the TNM staging system, 69.3% were stage IV, 26.73% were stage III and 3.96% were stage II. 73.26% of MPM were epitheloid, 4.95% sarcomatous and 20.79% were NOS (non otherwise specified) histological subtype. 14.85% of patients had surgery, 55.44% of patients received chemotherapy and 9.9% radiotherapy. Median OS was 11 months and PFS was ten months. OS by histological subtype was 11 months for epitheloid, 12.5 months for NOS and 5.5 months for sarcomatous MPM. OS by TNM stage was seven months for stage II, 17.5 months for stage III and 11 months for stage IV disease. Median OS was longer for patients younger than 65 (12 vs. 8.5 months, p=0.28), patients treated with pleurodesis (13 vs. 7.5 months, p=0.06) and patients who received chemotherapy (12.5 vs. 7.5 months, p=0.10). The overall survival and prognosis of patients with malignant pleural mesothelioma in Croatia is poor in accordance with the literature. The studied treatment methods offer only a modest survival benefit to our patients.
