Researchers out of the United Kingdom have reported on their 30-year surgical experience with malignant pleural mesothelioma, finding multimodality therapy combining surgery, chemotherapy and radiation to be most effective at prolonging mesothelioma prognosis.
During the period of the study, a total of 139 patients underwent surgical treatment and their progress was followed. The mean age of the participants was 58.9 years and 87% were males. Two-thirds of the participants exhibited disease on the right side of the body, which is common in pleural malignant mesothelioma.
The surgical procedures included extra-pleural pneumonectomy (EPP) for Butchart stage I patients or pleurectomy/decortication (PD) for patients with more advanced stage diagnosis. Following surgery, some participants underwent post-operative adjuvant therapy. This therapy included either chemotherapy, radiotherapy or both.
The longest survival median of 26 months occurred in the patients who received a pleurectomy/decortication and post-operative therapy with both chemotherapy and radiotherapy. Patients who underwent EPP experienced the most post-operative complications, particularly immediate post-operative infections and broncho-pleural fistulas.
Researchers noted that the EPP surgical procedure “whether or not combined with adjuvant therapy provided no significant survival advantage in comparison to pleurectomy/decortication.” And after univariate analysis (analysis that explores each variable separately), the strongest predictor of prolonged survival was the treatment approach combining pleurectomy/decortication, chemotherapy and radiation.
Patients with an epithelial mesothelioma diagnosis also experienced better survival. Results showed the stage at diagnosis did not influence long-term survival in this particular study.
Upon analyzing the results, the researchers concluded that “cytoreductive surgery combined with post-operative adjuvant therapy provided better survival despite either advanced disease or surgically less fit patients. Thus, pleurectomy/decortication may be the procedure of choice, given that neither surgical procedure (EPP or PD) is not curative.”
