Malignant pleural mesothelioma surgery

Malignant pleural mesothelioma (MPM) is an aggressively growing tumor that originates in the pleura (pleura). If left untreated, the tumor leads to death within a few months. Around 80 percent of cases can be linked to contact with asbestos. Although the use of asbestos has been banned in Switzerland since the 1990s, it is expected that the peak of new MPM cases has not yet been reached, as it takes an average of 40 years from contact with asbestos to the outbreak of the disease.

Treatment

There is no globally accepted, standardized guideline for the treatment of MPM that is adapted to the tumor stage – however, it is generally accepted that monotherapy alone is not sufficient for this aggressive tumor. According to current international guidelines (1-4), macroscopic complete resection in a multimodal treatment concept is the consensus recommendation. Most centers currently combine macroscopically complete resection with neoadjuvant (before surgery) or adjuvant (after surgery) chemotherapy. The combination of cisplatin and pemetrexed is considered to be the gold standard, as it offers the best chances of survival (on average twelve months with a response rate of 40%) and the best quality of life. Gemcitabine has comparable activity, but is less well tolerated.

Operational procedures

Pleurectomy/decortication or extrapleural pneumonectomy

A macroscopically complete resection can be achieved with a lung-preserving, extended pleurectomy/decortication (P/D) or an extrapleural pneumonectomy (EPP). In EPP, the pleura (= pleura), one lung, the pericardium (= pericardial sac) and the diaphragm (= diaphragm) are removed. In P/D, the same operation is performed with the difference that the lung tissue is almost completely preserved.
