Though associated with substantially prolonged survival, the favourable results of Sugarbaker's trimodality treatment for malignant pleural mesothelioma are controversial and have yet to be extensively reproduced. The aim was to evaluate the prospective medium-term (3-year) reproducibility of the results of trimodality treatment in a significant group of patients staged using the international IMIG classification. Forty-three patients with malignant pleural mesothelioma were candidates for extended pleuropneumonectomy, followed by chemo- and radiotherapy. At thoracotomy, 33 of the 43 surgical candidates underwent extended pleuropneumonectomy and 71% of the 30 evaluable operated patients completed the scheduled course of adjuvant chemotherapy. The perioperative mortality rate was 6% and the major morbidity rate 36%. At 3 years the overall survival of the 30 evaluable patients was 30% and the disease-free survival rate was 25%, with a prevalence of epithelial pI and pII IMIG stages. Clinical understaging was appreciable. Survival was less favourable for stage pIII and for mixed tumours. Most of the disease recurrences were due to incomplete local postsurgical monitoring. This series confirms the reproducibility of trimodality treatment for malignant pleural mesothelioma. The treatment is associated with prolonged survival in the case of early-stage tumours and has an acceptable complication rate. Early diagnosis, accurate staging, preoperative induction and better local monitoring are avenues to be explored when seeking to achieve curability of malignant pleural mesothelioma.
