The aim of this study was to clinicopathologically evaluation of 40 patients with pleural malignant mesothelioma and the main factors influencing their prognosis.
Methods: In this study patients with definitive diagnosis, who had been followed up for at least three years were studied based on gender, age presenting symptoms, and clinicopathological patterns.
Results: Male to female ratio of the study patients was three to one any the average age of them was 55 years. Chest pain was the most common symptoms in 34(85%) patients. Most of the study patients were in Buchard stage I (37/5%) and the epithelial form was the most common pathological pattern 25(62.5%). 19(47.5%) of cases received only radiotherapy and chemotherapy. Extrapleural pneumonectomy was performed on eight (20%) patients, seven (17.5%) patients underwent decortication and pleurectomy beside adjuvant therapy and 15% of the cases rejected any type of treatment. Surgical mortality occurred in one patient and the most common surgical complication was wound infection. The average survival rate was 12±1.2 months and the main factors influencing it were the patient's physiologic status, pathological form, stage of the disease and the pattern of pleural involvement.
Conclusions: Because the low survival rate after multimodality invasive treatments in mesothelioma, aggressive therapeutic methods were recommended in selected patients
