[Change in Therapy for Malignant Pleural Mesothelioma at Our Hospital].

When molecular target drug began to be used for chemotherapy to treat malignant pleural mesothelioma in 2014, we introduced this treatment strategy for 61 patients who were diagnosed and were being treated in our hospital. Chemotherapy was performed on 37 patients, while 12 patients underwent surgical remedy and best supportive care was provided to another 12 patients. Molecular target drug was used as the primary chemotherapy treatment in 14 cases, while it was the secondary treatment in 22 others. Pleural decortication was performed as the operative method for all the 12 cases requiring surgical remedy, and 2 of these cases were shifted to extrapleural pneumonectomy. By the chemotherapy, there were many cases of PS≥2, non‒epithelial type, advanced stage, LMR<2.74 of the biomarker. When we compared surgical remedy with the chemotherapy clinicopathologically. In the prognostic examination, in median survival time of all cases, as for 23 months, the chemotherapy, 31 months, the surgical remedy was not reached. Prognostic improvement of stage ⅢA was determined according to the stage of the chemotherapy. A multivariate variable analysis revealed that only a non‒sarcomatous type was a good prognostic factor, and surgery remedy was not.
