Abstract

The prognosis of malignant pleural mesothelioma is poor, but selected patients might benefit from multimodality treatment. To establish the means that are available to predict the variable course of the disease in malignant pleural mesothelioma patients, we retrospectively investigated the correlation of clinico-pathological features of 54 patients with survival. Twenty-three patients received treatment, while 31 were referred to supportive care only. The median survival of the entire group was 8.6 months. The 1-year survival was 33.2%. Univariate analysis of subgroups showed that age over 70 years, non-epithelial histologic type, patients treated with supportive care only, and delayed diagnosis were individually associated with lower survival. The European Organization for Research and Treatment of Cancer (EORTC) score showed a significant correlation with survival (P = 0.0146). The median survival of patients with an EORTC score of over 1.27 was 3.5 months, compared to 10.5 months for patients with an EORTC score of 1.27 or less. Tumor necrosis (TN) was a poor prognostic factor on univariate analysis (P = 0.0077). Patients with TN had a median survival of 7.0 months vs 15.5 months in negative cases. On multivariate analysis, TN was determined as an independent prognostic factor (P = 0.0349). EORTC prognostic scoring systems successfully stratify survival for a general hospital population, and TN might play an important role in poor outcome in malignant pleural mesothelioma.
