title: [Clinicopathological characteristics and prognosis of malignant pleural mesothelioma].
abstract: OBJECTIVE
  To investigate the clinicopathological characteristics and prognosis of malignant pleural mesothelioma.
  
  
  METHODS
  Thirty patients with malignant pleural mesothelioma diagnosed between January 2006 and June 2012 in our hospital were studied retrospectively. Clinical manifestations, radiological characteristics, endoscopic features, histopathology, and survival status were analyzed.
  
  
  RESULTS
  There were 15 males and 15 females, with a median age of 58 years. The commonest clinical symptoms were dyspnea on exertion (26 cases), followed by chest pain (15 cases). The main radiological manifestations were small to large amount of pleural effusions (28 cases), often accompanied by pleural thickening and/or pleural nodules.Of the 30 cases, 25 were diagnosed through medical thoracoscopy and 1 through surgical thoracoscopy. Thoracic lesions manifested as nodules of diffuse distribution on the diaphragmatic pleura and parietal pleura.Some pleural surface was covered with lesions like white tiles.Histopathological examination showed epithelial type in 24 cases, sarcomatoid type in 5 and biphasic type in 1 case.Immonohistological examination showed that the positive rates of calretinin, MC, D2∼40 were 27, 25 and 19 cases respectively.Fifteen patients received chemotherapy, 2 underwent pleurectomy, and 8 were treated with best supportive care. Twenty-four patients were followed for 1 month to 6 years, and 6 patients were lost.Overall survival time was 1-54 months. Those who survived longer than 24 months received chemotherapy with pemetrexed and cisplatin/carboplatin or pleurectomy.
  
  
  CONCLUSIONS
  Clinical manifestations of malignant pleural mesotheliome were nonspecific, medical thoracoscopy can make early diagnosis. The pathological diagnosis of malignant pleural mesothelioma was based on immunohistochemical examination, calretinin, MC and D2-40 had positive diagnostic value. Malignant pleural mesothelioma had poor prognosis, chemotherapy with pemetrexed and cisplatin/carboplatin could prolong the survival time of the patients.
