The results of a study published recently in The Journal of Thoracic and Cardiovascular Surgery supports the use of extrapleural pneumonectomy-based multimodal therapy in carefully selected patients with malignant pleural mesothelioma. The Journal is published by The American Association for Thoracic Surgery.
According to the research summary, the objective of the study was to evaluate the perioperative and long-term outcomes associated with extrapleural pneumonectomy for patients with malignant pleural mesothelioma. Pleural mesothelioma affects the lining of the chest cavity and lungs. Other forms of mesothelioma include pericardial, which affects the lining of the heart and is extremely rare; and peritoneal, which affects the lining of the abdomen. Mesothelioma is atributed almost exclusively to asbestos exposure.
According to the Multimedia Manual of Cardiothoracic Surgery, extrapleural pneumonectomy was introduced in the 1940s for the treatment of extensive infections of the lung and pleural space. Over the past 20 years, the extrapleural pneumonectomy technique has been modified and applied to the treatment of locally advanced malignant pleural mesothelioma, achieving substantial reductions in mortality. The surgery involves the removal of the lung with visceral and parietal pleurae, pericardium and diaphragm.
Researchers selected 70 patients between October 1994 and April 2008 to undergo the procedure. Prognostic factors included age, gender, side of disease, asbestos exposure, histology, positron emission tomography, date of surgery, neoadjuvant chemotherapy, completeness of cytoreduction, lymph node involvement, peioperative morbidity, adjuvant radiotherapy and pemetrexed-based chemotherapy.
The mean age of patients was 55 years. The median survival was 20 months, with a 3-year survival of 30 percent. Analyses showed improved survival for patients with asbestos exposure, negative lymph node involvement, and receipt of adjuvant radiation or postoperative pemetrexed-based chemotherapy.
The study was conducted by physicians from the University of Sydney, Department of Cardiothoracic Surgery, Royal Prince Alfred Hospital; The Baird Institute for Applied Heart and Lung Surgical; Department of Medical Oncology, Sydney Cancer Center, Royal Prince Alfred Hospital; and Department of Radiation Oncology, Sydney Cancer Center, Royal Prince Alfred Hospital; all in Sydney, Australia.
