[Malignant pleural mesothelioma: clinical characteristics, prognostic factors and treatment].
Malignant pleural mesothelioma soon leads to death no matter what type of treatment is provided. We discuss the clinical signs, prognostic factors and treatment given in 41 cases managed over the past 13 years in our oncology department. 32% had been exposed to asbestos, 61% were 60 years old or younger, 71% had a Karnofsky's index > or = 80% and 63% were stage I (Butchart). The first symptom leading to diagnosis was pain in 66% and mean time between first symptom and diagnosis was 3 months. Thirty patients never experienced full remission of disease: 15 were treated with palliative chemotherapy (CHT), 1 with palliative radiotherapy (RT), 5 with partial pleurectomy (PP) plus RT and/or CHT. Nine were given symptomatic treatment only. Only 11 (27%) patients experienced full remission after treatment: 7 had had extrapleural pneumonectomy, 2 had been given CHT and RT series and 4 had undergone PP with or without RT and/or CHT follow-up. Only 3 of these patients were still alive with no relapse more than 1 year later. Mean survival was 8 months. Univariate analysis revealed that the prognostic factors influencing survival were age and Karnofsky's index. Patients initially treated with surgery had a higher rate of survival. In conclusion, only Karnofsky's index and age were prognostic factors in our series. The better survival of patients initially treated surgically is probably related to prior screening.
